                               PROSPECTUS SUMMARY
 
  This summary highlights information contained in this prospectus. This
summary is not complete and may not contain all of the information you should
consider before investing in the common stock. You should read the entire
prospectus carefully.
 
                                  THE COMPANY
 
  We design, install and service custom integrated audio, video and data
display, conferencing and networking systems. These systems include state-of-
the-art technology that enhances our clients' ability to present and exchange
information. We also sell a wide range of portable multimedia presentation,
conferencing and networking equipment.
 
  We believe that, based on revenue, we are one of the largest companies in the
highly fragmented multimedia presentation and communication services industry.
Our strategy is to establish a national presence by growing internally
(including opening offices in new geographic markets) and acquiring
complementary businesses. We generated revenue of $41.5 million for the year
ended December 31, 1997, a 36% increase over 1996 revenue of $30.6 million, and
revenue of $26.7 million in the first six months of 1998, a 47% increase over
revenue of $18.2 million in the first six months of 1997. We generated
operating income of $1.7 million for the year ended December 31, 1997, a 197%
increase over 1996 operating income of $562,000, and operating income of
$925,000 in the first six months of 1998, a 135% increase over operating income
of $394,000 in the first six months of 1997. Since June 1, 1998, we have
completed three acquisitions, and we recently entered into non-binding letters
of intent to acquire two additional businesses. See "Business--Recent and
Potential Acquisitions" and "Pro Forma Consolidated Financial Data."
 
  We provide our clients one source for their multimedia presentation and
communication needs by:
 
  . offering sophisticated, "start to finish" design, procurement and
    installation services;
 
  . creating innovative integrated systems through a wide range of technical
    expertise;
 
  . providing high quality post-installation service and support; and
 
  . maintaining strong relationships with suppliers of market-leading
    products.
 
  We provide the extensive expertise necessary to design and integrate
presentation, performance, production, conferencing, networking and portable
systems. A presentation system typically includes video/data projection,
soundtrack and speech audio systems, audio and video source equipment and
remote control systems. A performance system may include public address
systems, stadium-size video displays, special audio and video effects, wide-
screen motion picture film systems, animated displays, automated theatrical
operations, and broadcast and closed-circuit television systems. A production
system may include equipment used for analog and digital video origination,
graphics design and post-production and distribution activities. A conferencing
system typically includes cameras, microphones, codec processing equipment,
television monitors, speakers and remote control equipment. A networking system
typically includes cabling that connects multiple rooms or buildings and the
switching, bridging and routing equipment that allows audio and video signals
to be directed to the proper location.
 
                                       3
<PAGE>
 
 
  The technologies that drive presentation, conferencing and networking
equipment are converging. As a result, businesses, government agencies and
educational institutions are requesting more sophisticated integrated solutions
for their communication needs. We believe that these needs are currently being
met primarily by:
 
  . small, regional firms that provide basic system integration services;
 
  . regional "box houses" (companies that focus on catalog sales of
    presentation and communication equipment); and
 
  . ""staging and rental" businesses (companies that primarily provide
    staging services for trade shows and other corporate events).
 
  We believe that we offer our clients more sophisticated design services
(including feasibility analysis, architectural coordination and technical
engineering) and a larger technically trained workforce than our small,
regional competitors. In addition, unlike most "box houses" and "staging and
rental" companies, we offer our clients a full range of services from initial
consultation to the design, engineering, procurement, fabrication and
installation of custom integrated multimedia communication systems. We also
provide post-installation support, repair, maintenance and on-site staffing and
operations. We believe that our ability to offer a comprehensive range of
services for state-of-the-art multimedia presentation and communication systems
distinguishes us from our competitors. We have completed approximately 1,000
integrated systems projects since January 1996 for clients such as Netscape,
Apple Computer, University of California, Stanford University, NASA-Ames
Research Labs and the U.S. Department of Energy.
 
                                    STRATEGY
 
  Our goal is to enhance our market position in the multimedia presentation and
communication services industry by continuing to grow internally and through
strategic acquisitions. Our strategy to achieve this goal contains the
following key elements:
 
  Serve as a Single Source Provider of Multimedia Communication Solutions. We
seek to become the provider of choice for all of our clients' multimedia
presentation and communication needs. We believe that offering a full spectrum
of state-of-the-art multimedia presentation and communication systems,
equipment and support services gives us a competitive advantage and enables us
to attract new clients and expand our business with existing clients. Although
our equipment maintenance, repair and rental services have not contributed
substantially to our revenue to date, we plan to enhance our efforts to market
those services in the future. We also seek to capitalize on opportunities to
offer new or expanded services tied to advances in the computer, data
communication and telecommunication industries.
 
  Stimulate Internal Growth. We plan to continue to expand domestically by
opening new offices in targeted geographic markets. Our decisions to open
offices in new markets are based on our review of demographic information,
existing client needs, business growth projections and the level of competition
in the area. We recently opened two additional offices in Southern California
and expect to open two offices in the metropolitan New York City area in 1999.
 
                                       4
<PAGE>
 
 
  Make Strategic Acquisitions. We believe that the multimedia presentation and
communication services industry is highly fragmented and consists primarily of
small companies that operate within limited geographical areas. We believe that
our industry offers substantial consolidation opportunities. We have acquired
three businesses since June 1, 1998 and recently entered into non-binding
letters of intent to acquire two additional businesses. We seek to acquire
selected businesses in targeted geographic markets and to expand the operations
of acquired companies through internal growth. We believe that our acquisitions
to date have allowed us to:
 
  . add new clients;
 
  . further develop our relationships with existing clients;
 
  . offer new services and capabilities; and
 
  . acquire experienced personnel.
 
See "Business--Recent and Potential Acquisitions."
 
  Develop and Maintain Strong Supplier Relationships. We currently have
distribution relationships with over 300 suppliers, including leading
communications technology, digital media hardware and software manufacturers
such as InFocus, NEC, Sony and PictureTel. We believe that our strong
relationships with suppliers have enabled us to attract and retain clients by
allowing us to offer a large selection of cutting-edge communications
equipment. We believe that we are able to negotiate attractive pricing and
volume discounts from suppliers because of our size and position in the
industry. We intend to continue to develop relationships and obtain exclusive
distribution agreements with companies that are developing new technologies in
order to ensure that our clients have access to the latest technology at
favorable prices.
 
  Focus on Staff Professional Development. We seek to employ highly qualified
and trained sales and technical personnel in order to provide superior service
to our clients. Our sales staff regularly attends manufacturer and industry
sponsored training to obtain manufacturer certification and expertise in the
features and benefits of the components and systems we sell and install. Our
engineering, project management and installation technicians participate (both
as instructors and students) in manufacturer and industry certification
programs for high-level technical training in system design, installation
procedures, and component applications, service and maintenance. Our personnel
also attend internally developed training programs for design and engineering,
sales skills and presentation and proposal writing.
 
  Our predecessor, Educational Industrial Sales, Inc. ("Educational"), was
incorporated in California in 1976. In October 1998, we changed our name from
Electronic Integrated Solutions ("EIS") to Intellisys Group, Inc. The
"Company," "we," "us" and "our" refer to Intellisys Group, Inc. and our wholly
owned subsidiary, B. Higginbotham Enterprises, Inc., unless we indicate
otherwise. Our executive offices are located at 140 East Dana Street, Mountain
View, California 94041. Our telephone number is (800) 828-6464.

  Unless we indicate otherwise, we have adjusted all information in this
prospectus to reflect our reincorporation in Delaware in October 1998 (the
"Reincorporation") and the mergers of our former wholly owned subsidiaries,
Educational and Alford Media Sales, Inc., into Intellisys Group, Inc. In the
Reincorporation, we converted our issued and outstanding common stock into
3,997,162 shares of Delaware common stock on a 4.047-for-one basis. Also,
unless we indicate otherwise, the information in this prospectus assumes that
the underwriters will not exercise their over-allotment option.

                                  RISK FACTORS
 
  You should consider the following factors carefully before deciding to
purchase common stock. This prospectus contains forward-looking statements.
These statements include words such as "may," "will," "expect," "believe,"
"intend," "anticipate," "estimate" or similar words. These statements are based
on our current beliefs, expectations and assumptions and are subject to a
number of risks and uncertainties. Actual results and events may vary
materially from those discussed in the forward-looking statements. We discuss
risks and uncertainties that might cause such a difference below and elsewhere
in this prospectus.
 
ABILITY TO MANAGE AND SUSTAIN GROWTH
 
  We have experienced rapid growth recently, in part due to our acquisition of
three businesses since June 1, 1998. This rapid growth may place a significant
strain on our resources. In order to continue to grow, we must, among other
things:
 
  . increase the amount of business we obtain from existing clients;
 
  . develop new clients;
 
  . continue to open offices in new geographic markets;
 
  . expand the range of integrated systems, equipment and support services we
    offer to our clients;
 
  . acquire complementary businesses in new and existing markets; and
 
  . retain key employees and recruit and train new employees.
 
  Until recently, most of our clients and operations have been located in the
San Francisco bay area. Through our recent acquisitions and by opening new
offices, we have expanded into other areas of the Western and Southwestern
United States. We plan to expand into additional geographic regions and
markets. We may not be able to translate our experience into success in new
geographic regions or markets. In addition, we cannot guarantee that:
 
  . we will be able to expand our business with current clients;
 
  . we will be able to develop new clients;
 
  . we will have adequate financial and other resources to open new offices
    or enter new markets;
 
  . any new offices will perform in a satisfactory manner;
 
  . we will be able to develop and offer new integrated systems, equipment
    and support services, or that any new integrated systems, equipment and
    support systems will be successful;
 
  . we will be able to identify and finance appropriate future acquisitions
    on favorable terms, or at all;
 
  . we will be able to retain key employees or hire new employees; or
 
  . any future business we may develop or acquire will perform in a
    satisfactory manner.
 
  As a result, we cannot assure you that we will be able to expand our business
or manage any future growth effectively and profitably.

INTEGRATION OF ACQUISITIONS
 
  Since June 1, 1998, we have acquired three businesses. We are currently
pursuing additional acquisitions and recently entered into non-binding letters
of intent to acquire two additional businesses. We may not be able to integrate
our recent or any future acquisitions successfully with existing operations
without substantial costs, delays or other problems. As we integrate acquired
businesses, key employees of the acquired companies could resign and
management's attention could be diverted from our ongoing business concerns. We
may not be able to implement operational improvements in, or exploit potential
synergies with, acquired businesses. Any of these factors could materially
adversely affect our operating results and financial condition. In addition,
any businesses we acquire may not perform as well as we may expect and could be
adversely affected by unforeseen liabilities.
 
ABILITY TO MAKE ADDITIONAL ACQUISITIONS
 
  We intend to pursue opportunities to expand our business through the
acquisition of selected companies in targeted geographic markets. We expect to
finance future acquisitions with proceeds from this offering, cash proceeds of
borrowings from third parties or the issuance of our common stock, promissory
notes or other securities. We cannot guarantee, however, that:
 
  . we will be able to identify appropriate acquisition candidates or
    negotiate acquisitions on favorable terms;
 
  . we will be able to obtain the financing necessary to complete future
    acquisitions; or
 
  . the issuance of our common stock or other securities in connection with
    any future acquisition will not result in a substantial dilution in the
    ownership interests of holders of our common stock.
 
CLIENT CONCENTRATION
 
  Each year a substantial portion of our revenue is derived from sales to a
relatively small number of clients. During 1997 and the first six months of
1998, approximately 19% of our revenue for each period resulted from sales to
our top 10 clients. The identities of our top 10 clients change from period to
period as we complete our contracts with them. If we fail to replace the
completed contracts with new contracts of similar size, our revenue and profits
may be adversely affected.
 
DEPENDENCE ON KEY PERSONNEL
 
  Our future success will depend in part upon the continued service of our key
technical, marketing and management personnel, particularly our Chairman,
President and Chief Financial Officer, Donald J. Esters. We will need to
attract and retain qualified employees, particularly technical personnel such
as design and systems integration engineers and service technicians. The
competition for qualified personnel is intense. We may not be able to retain
key employees or attract additional qualified personnel.
 
  The Company is the beneficiary of a key man insurance policy on the life of
Mr. Esters in the amount of $1,000,000.
 
                                       10

COMPETITION
 
  No firm data exists on the size of the multimedia presentation and
communication services industry and the number and size of competitors within
the industry. However, we believe, based on our experience in the industry,
that the multimedia presentation and communication services industry is highly
competitive and highly fragmented. We compete primarily with small, regional
firms that offer more limited services than ours. However, some participants in
the industry have national, full service businesses and greater capabilities
and financial resources than ours. In addition, non-traditional competitors who
offer more mature and sophisticated products and services (such as
telecommunications, computing and energy management companies) have begun to
add multimedia presentation and communication services and products to their
existing technology products and services. Our primary competitors are:
 
  . audiovisual equipment dealers;
 
  . companies that rent and sell audiovisual equipment, primarily in
    connection with staging services for trade shows and other corporate
    events;
 
  . independent design consulting firms;
 
  . electrical contractors;
 
  . manufacturers' sales and service divisions;
 
  . office superstores and consumer electronics chains; and
 
  . the in-house communications staffs of many clients and potential clients.
 
  We believe that the multimedia presentation and communication services
industry will become more consolidated in the future and, as a result, may
become more competitive. We could be adversely affected if existing competitors
expand their integrated systems businesses, if new competitors with greater
resources than ours enter the industry or if our clients or potential clients
choose to service their multimedia presentation and communication needs
internally.
 
DEPENDENCE ON KEY SUPPLIERS
 
  We rely on outside vendors to supply the components we sell to our clients.
Our future success will depend, in part, on our ability to maintain favorable
pricing, product availability and other supply terms with our current suppliers
and to develop relationships with new suppliers. We cannot assure you that we
will be able to maintain our favorable relationships with current suppliers or
develop new supplier relationships. We do not maintain an inventory large
enough to protect us against an interruption of supply, particularly if we were
required to obtain new products or products from alternative sources. In 1997,
52.6% of our revenue was derived from our sale of products supplied by our 10
largest suppliers, with products supplied by InFocus accounting for
approximately 15.6% of revenue in 1997 and approximately 13.3% of revenue in
the six months ended June 30, 1998.
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
  We may experience quarter-to-quarter fluctuations in our results of
operations as a result of a variety of factors, including:
 
  . our success in replacing completed contracts with new contracts of
    similar size;
 
  . changes in the mix of revenue between integrated systems and portable
    equipment that result in changes in profit margins;
 
                                       11
<PAGE>
 
  . the size and timing of acquisitions, expenses incurred in connection with
    those acquisitions and the integration of acquisitions into our business;
 
  . client demand for our systems and equipment;
 
  . the timing and cost of adding new personnel;
 
  . competitive conditions; and
 
  . general economic conditions.
 
  In reviewing our results of operations, you should not place undue emphasis
on quarter-to-quarter comparisons. Our results in any quarter may not be
indicative of the results we may achieve in any subsequent quarter or for the
full year. Quarterly fluctuations in operating results may result in
volatility in the market price of our common stock. If our results of
operations for any quarter are less favorable than the results expected by the
market, the market price of the common stock held by our stockholders would be
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Selected Quarterly Results of
Operations."
 
EFFECT OF ECONOMIC CONDITIONS
 
  We generate our revenue in large part from clients in the computer hardware
and software industry and other businesses that are cyclical in nature and
subject to changes in national, regional and industry economic conditions. We
could be adversely affected by any national, regional or industry economic
downturn, particularly by a recession in the computer hardware and software
industry, that results in decreased spending on multimedia presentation and
communication systems, equipment and support services.
 
RAPID TECHNOLOGICAL CHANGE
 
  Rapid technological change, including frequent new products, product
obsolescence and changing client needs, characterizes our industry. This rapid
change has contributed to our past growth. In order to succeed in the future,
we will need to continue to:
 
  . track industry developments and trends;
 
  . identify new products in a variety of communication media;
 
  . offer state-of-the-art products to clients;
 
  . integrate new technologies; and
 
  . respond to changing client requirements.
 
  We cannot assure you that rapid technological changes will continue to occur
or that, if they do, we will respond to them successfully.
 
CONTROL BY SINGLE STOCKHOLDER
 
  Immediately following the offering, Donald J. Esters will beneficially own
approximately 39.1% of the outstanding common stock, assuming that we complete
our acquisition of Proline Industries, Inc. and that promissory notes issued
or to be issued in connection with the Aurora Visual Systems and Digital
Networks Corporation acquisitions convert automatically into common stock upon
the closing of this offering. Accordingly, Mr. Esters will be able to
influence significantly any stockholder vote, including any vote on the
election of directors. Mr. Esters' interests could conflict with the interests
of our other stockholders.

MANAGEMENT INFORMATION SYSTEMS; YEAR 2000
 
  Our success depends in part on the accuracy and reliability of the computer
software programs and operating systems we use in our business and the
information generated by these systems. Recently, we have begun to replace and
upgrade our management information systems. We expect to complete this process
in the first quarter of 1999. We cannot assure you that we will be able to
accomplish this transition to new software without disrupting our business,
delaying the integration of newly acquired businesses or incurring higher costs
than expected.
 
  Our new software is designed to be year 2000 compliant, but we cannot assure
you that it contains all necessary data code changes. We have evaluated our
other software programs (such as engineering and design programs), and we
believe that these programs are year 2000 compliant. We expect all of our
critical systems to be year 2000 compliant by December 31, 1999.
 
  Certain products we sell may be affected by year 2000 issues. We plan to
obtain information from our suppliers regarding their products' compliance with
year 2000 issues. We do not have any information that makes us believe that
year 2000 issues relating to our internal systems or to products or systems we
sell to our clients will adversely affect us. At this time, however, we cannot
assure you that:
 
  . all of our systems will be year 2000 compliant by 2000;
 
  . the products or systems we have sold to clients are year 2000 compliant;
 
  . we will not encounter year 2000 compliance issues in any business that we
    acquire; or
 
  . any failure on our part or on the part of our clients or suppliers to
    achieve full year 2000 systems compliance will not adversely affect us.
 
  Although we have not yet formulated a contingency plan for year 2000
compliance, we plan to continue to assess year 2000 risks to determine whether
we need to do so. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Year 2000 Issues."
 
NO PRIOR MARKET FOR COMMON STOCK; DETERMINATION OF PUBLIC OFFERING PRICE
 
  There has been no public market for our common stock. We are applying to list
the common stock for trading on the Nasdaq National Market System. We do not
know whether investor interest in the Company will lead to the development of a
trading market or, if a trading market develops, how liquid that market will
be. We will determine the initial public offering price for the shares of
common stock through our negotiations with the underwriters. You may not be
able to sell your shares at or above the initial public offering price. See
"Underwriting."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of a large number of shares of common stock in the market after the
offering or the perception that sales may occur could cause the market price of
our common stock to drop. 6,162,859 shares of common stock will be outstanding
immediately after the offering, including 43,078 shares of common stock that we
expect to issue in connection with our acquisition of Proline Industries, Inc.
and 122,619 shares of common stock that we expect to issue upon the automatic
conversion of convertible promissory notes issued or to be issued in connection
with the Aurora Visual Systems and Digital Networks Corporation acquisitions.
The 2,000,000 shares sold in this
 
                                       13
<PAGE>
 
offering (plus any shares issued upon exercise of the underwriters' over-
allotment option) will be freely tradable, except for shares held by
"affiliates" of the Company, as that term is defined under Rule 144 under the
Securities Act. Of the remaining shares,     are subject to lock-up agreements
in which the holders of the shares have agreed not to sell any shares for a
period of 180 days after the date of this prospectus without the prior written
consent of the representatives of the underwriters. The shares not subject to
lock-up agreements are "restricted securities" as defined in Rule 144 under the
Securities Act. These shares may be sold in the future without registration
under the Securities Act to the extent permitted by Rule 144 or an exemption
under the Securities Act. See "Shares Eligible for Future Sale."
 
  After this offering, we intend to file a registration statement on Form S-8
under the Securities Act to register the 750,000 shares of common stock that
are available for grant under our 1998 Equity Participation Plan and the
409,916 shares issuable upon exercise of options otherwise outstanding. We
expect the registration statement on Form S-8 to become effective immediately
upon filing. Options to purchase 238,746 shares of Common Stock are either
vested or vest within 60 days of October 1, 1998. Before the offering closes,
we plan to grant stock options to purchase     shares of common stock under our
1998 Equity Participation Plan. After the offering is effective, shares covered
by the registration statement on Form S-8 will be eligible for sale in the
public markets, subject to Rule 144 limitations applicable to affiliates as
well as to the limitations on sale and vesting described above. See
"Management."
 
DILUTION
 
  We expect the initial public offering price to be substantially higher than
the net tangible book value per share of the common stock. Therefore, you will
incur immediate and substantial net tangible book value dilution. You may incur
additional dilution if holders of stock options exercise their options or if
holders of warrants exercise their warrants to purchase common stock. See
"Dilution."
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
  Certain provisions of our Certificate of Incorporation and Bylaws could make
it more difficult for a third party to acquire control of the Company, even if
a change in control would be beneficial to stockholders. These provisions
include a staggered Board of Directors, supermajority voting requirements for
business combinations, a requirement that stockholders act at meetings rather
than by written consent and the authority of our Board of Directors to issue,
without stockholder approval, preferred stock with terms set by the Board of
Directors. See "Description of Capital Stock."
 
PAYMENT OF DIVIDENDS ON COMMON STOCK
 
  We have agreements that limit our ability to pay dividends on our common
stock. We intend to retain any future earnings to fund the operation and
expansion of our business. We do not anticipate paying cash dividends on our
shares in the foreseeable future. See "Description of Capital Stock" and
"Dividend Policy."

<PAGE>
 
                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 2,000,000 shares of
common stock in this offering are estimated to be approximately $17.8 million
based upon an assumed offering price per share of $10, after deducting the
underwriting discount and commissions and estimated offering expenses. The
Company expects to use approximately $4.0 million of the estimated net proceeds
to:
 
  . reduce by approximately $3.5 million outstanding indebtedness under the
    Company's $15 million secured credit facility with Sanwa Business Credit
    Corporation, which bears interest at rates of 0.50% over the prime rate
    or 3.25% over the Euro-Rate, depending on the type and amount of the
    loans; and
 
  . repay outstanding indebtedness in the amount of $500,000 under a
    subordinated promissory note of the Company that is due and payable
    immediately following this offering.
 
  The Company expects to use the remainder of the net proceeds to fund possible
future acquisitions and for working capital. Pending application of the net
proceeds as described above, the net proceeds of the offering will be invested
in interest-bearing or dividend-bearing investment grade securities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
  The Company continues to evaluate potential acquisitions and engage in
discussions with several potential acquisition candidates. The Company entered
into a non-binding letter of intent on August 23, 1998 with Aurora Visual
Systems, a portable systems business, with respect to the Company's acquisition
of substantially all of Aurora's assets in exchange for an aggregate purchase
price of $1.4 million and the Company's assumption of certain liabilities. On
October 5, 1998, the Company entered into a non-binding letter of intent to
acquire all of the outstanding capital stock of Proline Industries, Inc. for an
aggregate purchase price of $6.4 million. Proline is an integrated systems
business with offices in Washington, Oregon and Northern California. A portion
of the purchase prices for the Company's potential acquisitions of Aurora and
Proline will be financed with the proceeds of a private placement of the
Company's preferred stock, which the Company expects to complete prior to the
closing of the offering. The Company is not currently a party to any binding
agreements or commitments with respect to any future acquisitions. There can be
no assurance that any future acquisitions, including the Aurora and Proline
acquisitions, will be consummated on terms favorable to the Company, if at all.
 
                                DIVIDEND POLICY
 
  The Company presently anticipates that it will retain all of its future
earnings to finance the expansion of its business and provide working capital.
Therefore, the Company does not anticipate paying any cash dividends on the
common stock in the foreseeable future. In addition, certain of the Company's
debt instruments contain covenants that restrict the Company's ability to
declare dividends. The Company has not paid any dividends on its common stock
in the past. The Company's Board of Directors has the discretion to determine
whether to declare or pay dividends in the future, and any determination will
be based upon the Company's results of operations, financial condition, capital
requirements, contractual restrictions and other factors the Board of Directors
deems relevant.

  The following table sets forth the capitalization of the Company (i) on an

                                    DILUTION
 
  As of June 30, 1998, the net tangible book value of the Company on a pro
forma basis, after giving effect to the Recent Acquisitions and the Potential
Acquisitions (as defined in "Selected Consolidated Financial Data") and the
issuance of preferred stock in connection with the Potential Acquisitions was
approximately $3.1 million, or $.61 per share of common stock outstanding. See
"Pro Forma Consolidated Financial Data." Net tangible book value per share
represents the amount of total tangible assets less total liabilities divided
by the number of shares of common stock outstanding. After giving effect to the
transactions described above and the sale by the Company of 2,000,000 shares of
common stock in this offering, the application of the net proceeds from this
offering as described in "Use of Proceeds" and the automatic conversion of
convertible promissory notes into 122,619 shares of common stock immediately
following this offering, the pro forma net tangible book value of the Company
at June 30, 1998 would have been $20.8 million, or $2.89 per share. This
represents an immediate increase in net tangible book value of $2.28 per share
to existing shareholders and an immediate dilution of $7.11 per share to new
shareholders purchasing shares at the assumed initial public offering price of
$10.00 per share. The following table illustrates this per share dilution:

SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
  Sales and installation revenue. Sales and installation revenue was $26.7
million in the first six months of 1998 compared to $18.2 million for the same
period in 1997, an increase of 47%. Of the increase, approximately $6.9 million
was primarily attributable to increases in the number of integrated systems
sold and the average integrated system contract size as well as the number of
portable equipment sold. The remaining $1.6 million increase in revenues in the
first six months of 1998 compared to the first six months of 1997 resulted from
revenues attributable to the acquisitions of Higginbotham and Alford on June 1,
1998.
 
  Cost of sales and gross profit. Cost of sales increased to $19.4 million, or
73% of revenue, in the first six months of 1998 compared to $13.6 million, or
75% of revenue, in the same period in 1997. The increase in cost of sales
corresponded to the increase in revenue. The Company's gross margins are
generally higher on sales of integrated systems than on portable equipment
sales. Cost of sales decreased as a percentage of revenue due primarily to an
increase in sales of higher margin integrated systems as a percentage of
revenue and to improved margins on portable equipment sales.

  Selling, general and administrative expenses. Selling, general and
administrative expenses were $6.4 million, or 24% of revenues, in the first six
months of 1998 compared to $4.2 million, or 23% of revenue, for the same period
in 1997. The increase reflected the Company's decision to continue to invest in
its sales and administrative functions, including opening and staffing a new
sales office in Englewood, Colorado in the summer of 1997.
 
  Interest and other income. For the first six months of 1998, interest expense
was $242,000 compared to $185,000 for the same period in 1997. The increase in
interest expense reflected the increase in the Company's aggregate borrowings
for working capital purposes. In the first half of 1998, the Company also
recorded $165,000 of other income to reflect the management fees resulting from
the management of Digital's operations prior to the consummation of the Digital
acquisition.
 
  Income taxes. The Company used an effective income tax rate of 40% for the
six months ended June 30, 1998 and June 30, 1997. Management believes that the
40% tax rate used for the six months ended June 30, 1998 was consistent with
the Company's historical tax provision.
 
YEARS ENDED DECEMBER 31, 1997 AND 1996
 
  Sales and installation revenue. Sales and installation revenue increased 36%
to $41.5 million in 1997 from $30.6 million in 1996, primarily as a result of
increases in the number of integrated systems sold and the average integrated
system contract size as well as the number of portable equipment sold.
 
  Cost of sales and gross profit. Cost of sales was $30.2 million, or 73% of
revenue, in 1997 compared to $23.0 million, or 75% of revenue, in 1996. The
Company's gross margins are generally higher on sales of integrated systems
than on portable equipment sales. The lower cost of sales in 1997 as a
percentage of revenue reflected an increase in sales of higher margin
integrated systems as a percentage of revenue.
 
  Selling, general and administrative expenses. Selling, general and
administrative expenses increased to $9.7 million in 1997 from $7.0 million in
1996. These expenses represented 23% of revenue in each of 1996 and 1997. The
increase in expenses in 1997 was attributable to the addition of employees to
support increased sales, the opening of the Englewood, Colorado office in the
summer of 1997 and expansion of other Company facilities.
 
  Interest expense. In 1997, interest expense was $351,000 compared to $269,000
in 1996. The increase in interest expense reflected the increase in the
Company's aggregate borrowings for working capital and equipment loans.
 
  Income taxes. In 1997, the Company's income tax provision was $523,000
compared to $98,000 in 1996. The increase in tax provision from 1996 to 1997
was proportionate to the increased pre-tax income.

YEARS ENDED DECEMBER 31, 1996 AND 1995
 
  Sales and installation revenue. Sales and installation revenue increased 20%
to $30.6 million in 1996 from $25.5 million in 1995, principally as a result of
an increase in the number of integrated systems and portable equipment sold.
Revenue for 1995 included revenue from a large single integrated system
contract (the "1995 Contract"), which was substantially completed during 1995.
 
  Cost of sales and gross profit. In 1996, cost of sales was $23.0 million, or
75% of revenue, compared to $17.9 million, or 70% of revenue, in 1995. The
Company's gross margins are generally higher on sales of integrated systems
than on portable equipment sales. The increase in cost of sales as a percentage
of revenue in 1996 primarily reflected a decrease in higher margin integrated
systems sales as a percentage of revenue, primarily as a result of the
completion of the 1995 Contract in early 1996.
 
  Selling, general and administrative expenses. In 1996, selling, general and
administrative expenses were $7.0 million compared to $6.2 million in 1995.
These expenses represented 23% of revenue in 1996 and 24% of revenue in 1995.
The increase in expenses reflected the full-year cost of maintaining new
Company sales offices. The Company opened new sales offices in Irvine,
California and Tempe, Arizona in the first quarter of 1995 and in San Francisco
in the fourth quarter of 1995. The increase was also attributable to the
addition of personnel to support increased sales.
 
  Interest expense. In 1996, interest expense was $269,000 compared to $247,000
in 1995. The increase in interest expense reflected the increase in the
Company's aggregate borrowings for working capital purposes.
 
  Income taxes. In 1996, the Company's income tax provision was $98,000
compared to $483,000 in 1995. The lower tax provision in 1996 was in proportion
to a decrease in pre-tax income.

  The Company may experience quarter-to-quarter fluctuations in its results of
operations as a result of a variety of factors, including the Company's success
in replacing completed contracts with new contracts of similar size, changes in
the mix of integrated systems and portable equipment revenue that result in
changes in profit margins, the size and timing of acquisitions, expenses
incurred in connection with those acquisitions and the integration of
acquisitions into the Company's business, client demand for the Company's
systems and equipment, the timing and cost of adding new personnel, competitive
conditions and general economic conditions. The Company sells its systems on a
project-by-project basis, and quarterly results of operations may also be
affected by the timing of the completion of projects and the commencement of
work on new projects. The Company's gross margins are generally higher on sales
of integrated systems than on portable equipment sales. The Company has
experienced and expects to continue to experience variations in gross profit as
a result of quarter-to-quarter changes in the amount of higher margin
integrated systems sales as a percentage of revenue and changes in profit
margins on integrated systems sales and portable equipment sales. The Company
believes that quarter-to-quarter comparisons of its results of operations are
not necessarily meaningful or indicative of the results the Company may achieve
in any subsequent quarter or full year. See "Risk Factors--Fluctuations in
Quarterly Operating Results."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company has financed its operations primarily through internal cash flow
and bank borrowings. Net cash used in operations for the first six months of
1998 was $752,000. The negative cash flow from operations was primarily
attributable to increases in accounts receivable, inventory and accounts
payable. For the first half of 1998, net cash used in investing activities was
$2.7 million, principally for the Recent Acquisitions. For the first six months
of 1998, net cash provided by financing activities was $3.4 million, consisting
of loan proceeds from a lender, equity capital contributed by new investors,
and net borrowings under the Company's credit agreement with Wells Fargo Bank,
N.A. (the "Prior Credit Facility.")
 
  For the year ended December 31, 1997, net cash provided by operating
activities was $238,000. This was primarily due to cash generated by net income
before non-cash expenses for depreciation and amortization. Cash used in
investing activities for 1997 of $507,000 primarily consisted of additions of
equipment. Cash provided by financing activities in 1997 consisted of $349,000,
principally from borrowings under the Company's Prior Credit Facility.
 
  The Company entered into the Prior Credit Facility in June 1997. The Prior
Credit Facility was subsequently amended August 1997 to increase the line of
credit to $7.0 million. The Prior Credit Facility consisted of a $7.0 million
revolving credit line and a term credit facility of $740,000, secured by
substantially all of the Company's assets. The limit on aggregate borrowings
depended on the balance of the Company's eligible accounts receivable and
inventories. Loans from the credit line bore interest at the prime rate or at
2.25% over LIBOR. At June 30, 1998, the Company had aggregate borrowings of
approximately $6.8 million outstanding under the Prior Credit Facility.
 
  In September 1998, the Company entered into a $15.0 million line of credit
(the "Credit Facility") with Sanwa Business Credit Corporation and terminated
and paid all outstanding indebtedness under the Prior Credit Facility. The
Credit Facility is secured by substantially all of the Company's assets. The
Credit Facility includes revolving advances that vary according to the
Company's eligible accounts
 
                                       32
<PAGE>
 
receivable and inventories and bears interest at rates of 0.50% over the prime
rate or 3.25% over the Euro-Rate, depending on the type and amount of the
loans. The Company is required either to maintain a daily average loan amount
of $7.5 million or pay a fee equal to the shortfall multiplied by the
applicable interest rate charged for prime rate-based loans. Amounts borrowed
under the Credit Facility were used to repay borrowings under the Prior Credit
Facility and other bank debt of acquired companies and will be used to finance
the ongoing working capital requirements of the Company as well as potential
acquisitions. At October 1, 1998, the Company had total borrowings of
$12.2 million outstanding under the Credit Facility. The Company intends to
reduce this debt to $7.5 million with a portion of the net proceeds from the
offering. See "Use of Proceeds."
 
  The Company believes that the Credit Facility, together with proceeds from
the offering and funds generated by the Company's operations, will provide the
Company with sufficient liquidity and capital resources to finance the
Company's operations and planned expenditures through 1999.
 
YEAR 2000 ISSUES
 
  The year 2000 issue is the result of computer-controlled systems using two
digits rather than four to define the applicable year. For example, computer
programs that have time-sensitive software may recognize a date ending in "00"
as the year 1900 rather than the year 2000. This could result in system failure
or miscalculations causing disruptions of operations including, among other
things, a temporary inability to process transactions, send invoices, or engage
in similar normal business activities.
 
  In anticipation of potential year 2000 problems, the Company has begun to
replace and upgrade its management information systems with a platform designed
to be year 2000 compliant. The Company expects to complete this process in the
first quarter of 1999. The Company has retained a consulting firm to coordinate
successful system implementation, including testing of year 2000-related
problems. Testing for year 2000 compliance will commence upon system
implementation and will continue throughout 1999. The Company presently
believes that with successful system conversions, the year 2000 issue will not
pose significant operational problems for its systems. However, although the
Company's new software is designed to be year 2000 compliant, there can be no
assurance that it contains all necessary data code changes. If the Company does
not complete its planned conversions in a timely fashion, year 2000 could have
a material impact on the operations of the Company.
 
  The Company expects that assessment, remediation and contingency planning
activities for its internal systems will be ongoing through 1999. The Company
currently expects the total cost for these activities to be approximately
$450,000. This total cost estimate does not include replacement of internal
software and hardware in the normal course of business. The costs of the
project and the date established for completion of year 2000 modifications are
based on management's best estimates, which were derived using numerous
assumptions of future events, including the continued availability of certain
resources, third party modification plans and other factors. However, there can
be no guarantee that these estimates will be achieved, and actual results could
differ materially from those anticipated. Specific factors that might cause
such material differences include, but are not limited to, the availability and
cost of personnel trained in this area, the ability to locate and correct all
relevant computer codes, potential acquisitions and similar uncertainties.
 
  Certain products that the Company sells may be affected by year 2000 issues.
The Company intends to obtain information from its suppliers regarding their
products' year 2000 compliance. The
 
                                       33
<PAGE>
 
Company does not currently have any information that would lead it to believe
that year 2000 issues relating to its internal systems or to products or
systems sold to customers will have a material adverse impact on the Company's
financial condition or overall trends in results of operations. Since third
party year 2000 compliance is not within the Company's control, and since the
Company has not yet obtained compliance information from its suppliers, there
can be no assurance that the failure by a supplier to achieve year 2000
compliance would not adversely affect the Company. Furthermore, the purchasing
patterns of the Company's clients may be affected by year 2000 issues if these
companies spend significant resources on year 2000 compliance or are adversely
affected by failure to address year 2000 issues in a timely manner. These
expenditures could result in reduced funds available for the Company's
services, which could adversely affect the Company. Although the Company has
not formulated a contingency plan to date, it plans to continue to assess year
2000 risks to determine whether it needs to do so. See "Risk Factors--Year 2000
Issues."
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  In 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 130, Reporting Comprehensive
Income, which establishes standards for reporting and displaying comprehensive
income and its components. The statement is effective for fiscal years
beginning after December 15, 1997 and will be adopted by the Company in 1998.
This statement is not expected to have a material impact on the Company's
disclosures within the consolidated financial statements.
 
  In 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information, which establishes standards for the way
that public business enterprises are to report information about operating
segments in the annual financial statements and requires those enterprises to
report selected information about operating segments in interim financial
reports issued to shareholders. The statement is effective for periods
beginning after December 15, 1997, and will be adopted by the Company in 1998.
The Company is currently evaluating what impact this pronouncement will have on
the disclosures within the consolidated financial statements.
 
  In 1998, the FASB issued SFAS No. 133, "Accounting for Derivative Instruments
and Hedging Activities." The SFAS establishes accounting and reporting
standards requiring that every derivative instrument be recorded in the balance
sheet as either an asset or liability measured at its fair value. The SFAS
requires that changes in the derivative's fair value be recognized currently in
earnings unless specific hedge accounting criteria are met. Accounting for
qualifying hedges allows a derivative's gains and losses to offset related
results on the hedged item in the income statement, and requires a company to
formally document, designate, and assess the effectiveness of transactions that
receive hedge accounting. The statement is effective for fiscal years beginning
after June 15, 1999 and early adoption is permitted. This statement is not
expected to have a material impact on the Company's results of operations.
 
  In 1998, the American Institute of Certified Public Accountants ("AICPA")
issued Statement of Position ("SOP") No. 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use." The SOP is effective
for fiscal years beginning after December 15, 1998 and earlier adoption is
permitted. The adoption of SOP No. 98-1 is not expected to have a material
impact on the Company's results of operations.

OVERVIEW
 
  Intellisys Group, Inc. designs, installs and services custom integrated
audio, video and data display, conferencing and networking systems. These
systems include state-of-the-art technology that enhances the Company's
clients' ability to present and exchange information. The Company also sells a
wide range of portable multimedia presentation, conferencing and networking
equipment.
 
  The Company believes that, based on revenue, it is one of the largest
companies in the highly fragmented multimedia presentation and communication
services industry. The Company's strategy is to establish a national presence
by growing internally (including opening offices in new geographic markets) and
acquiring complementary businesses. We generated revenue of $41.5 million for
the year ended December 31, 1997, a 36% increase over 1996 revenue of $30.6
million, and revenue of $26.7 million in the first six months of 1998, a 47%
increase over revenue of $18.2 million in the first six months of 1997. We
generated operating income of $1.7 million for the year ended December 31,
1997, a 197% increase over 1996 operating income of $562,000, and operating
income of $925,000 in the first six months of 1998, a 135% increase over
operating income of $394,000 in the first six months of 1997. Since June 1,
1998, we have completed three acquisitions, and we recently entered into non-
binding letters of intent to acquire two additional businesses. See "--Recent
and Potential Acquisitions" and "Pro Forma Consolidated Financial Data."
 
  The Company provides its clients one source for their multimedia presentation
and communication needs by:
 
  . offering sophisticated, "start to finish" design, procurement and
    installation services;
 
  . creating innovative integrated systems through a wide range of technical
    expertise;
 
  . providing high quality post-installation service and support; and
 
  . maintaining strong relationships with suppliers of market-leading
    products.
 
  The Company provides the extensive expertise necessary to design and
integrate presentation, performance, production, conferencing, networking and
portable systems. A presentation system typically includes video/data
projection, soundtrack and speech audio systems, audio and video source
equipment and remote control systems. A performance system may include public
address systems, stadium-size video displays, special audio and video effects,
wide-screen motion picture film systems, animated displays, automated
theatrical operations, and broadcast and closed-circuit television systems. A
production system may include equipment used for analog and digital video
origination, graphics design and post-production and distribution activities. A
conferencing system typically includes cameras, microphones, codec processing
equipment, television monitors, speakers and remote control equipment. A
networking system typically includes cabling that interconnects multiple rooms
or buildings and the switching, bridging and routing equipment that allows
audio and video signals to be directed to the proper location.
 
                                       35

  The technologies that drive presentation, conferencing and networking
equipment are converging. As a result, businesses, government agencies and
educational institutions are requesting more sophisticated integrated solutions
for their communication needs. The Company believes that these needs are
currently being met primarily by:
 
  . small, regional firms that provide basic system integration services;
 
  . regional "box houses" (companies that focus on catalog sales of
    presentation and communication equipment); and
 
  . ""staging and rental" businesses (companies that primarily provide
    staging services for trade shows and other corporate events).
 
  The Company believes that it offers more sophisticated design services
(including feasibility analysis, architectural coordination and technical
engineering) and a larger technically trained workforce than its small,
regional competitors. Additionally, unlike most "box houses" and "staging and
rental" companies, the Company offers its clients a full range of services from
initial consultation to the design, engineering, procurement, fabrication and
installation of custom integrated multimedia communication systems. The Company
also provides post-installation support, repair, maintenance and on-site
staffing and operations. The Company believes that its ability to offer a
comprehensive range of services for state-of-the-art multimedia presentation
and communication systems distinguishes it from its competitors. The Company
has completed approximately 1,000 integrated systems projects since January
1996 for clients such as Netscape, Apple Computer, University of California,
Stanford University, NASA-Ames Research Labs and the U.S. Department of Energy.
 
INDUSTRY OVERVIEW
 
  Historically, customers of sound systems installation businesses, which
specialized primarily in music and paging systems, also engaged these
businesses to provide multimedia presentation and communication systems. For
the most part, these businesses served a limited geographical area. In the mid-
1980's, as digital imaging, sound processing and control technologies
developed, companies began to offer display devices and videoconferencing and
integrated remote control equipment, in addition to sound systems. Around the
same time, clients began to request more comprehensive services that included
strategic planning, consistent buying power and increased out-sourced services.
To meet these client needs, firms similar to the Company began to employ sales
professionals, engineers and technicians trained in a wide range of multimedia
technologies.
 
  The multimedia presentation and communication services industry includes
firms engaged in the design, installation and maintenance of electronic
systems, which can be combined through networked control devices. Systems
combine optical and video display systems, audio reproduction systems, video
origination, recording and distribution systems, and single and multi-point
remote control systems. Multimedia presentation and communication services
firms provide services and systems to business and industry, education,
government, health services, religious and community agency customers. The
Company believes that the multimedia presentation and communication services
industry is currently highly fragmented, with no clear market leader.
 
                                       36
<PAGE>
 
  The Company believes that there is a trend toward consolidation in the
industry as firms move to establish a national presence through the acquisition
of local or regional firms. In addition, non-traditional competitors, offering
more mature and sophisticated products and services (such as
telecommunications, computing and energy management companies), have begun to
add multimedia presentation and communication services and products to their
existing technology products and services.
 
  The convergence of traditional audiovisual presentation media and computer-
based delivery has generated demand for high-technology presentation,
production and performance products and services. The need for faster access to
people and information and the goal of reduced travel have led to increased
demand for high-quality audio and video conferencing systems. Due to increasing
LAN/WAN network capacity, distribution of real-time audio and video media
content through a network to remote sites (e.g., for distance learning and
network-based conferencing) has become more cost-effective and commonplace.
 
STRATEGY
 
  The Company's goal is to enhance its market position in the multimedia
presentation and communication services industry by continuing to grow
internally and through strategic acquisitions. The Company's strategy to
achieve this goal contains the following key elements:
 
  Serve as a Single Source Provider of Multimedia Communication Solutions. The
Company seeks to become the provider of choice for all of its clients'
multimedia presentation and communication needs. The Company believes that
offering a full spectrum of state-of-the-art multimedia presentation and
communication integrated systems, equipment and support services gives it a
competitive advantage and enables it to attract new clients and expand its
business with existing clients. Although the Company's equipment maintenance,
repair and rental services have not contributed substantially to its revenue to
date, the Company plans to enhance its efforts to market those services in the
future. The Company seeks to capitalize on opportunities to offer new or
expanded services tied to advances in the computer, data communication and
telecommunication industries.
 
  Stimulate Internal Growth. The Company also plans to continue to expand
domestically by opening new offices in targeted geographic markets. The
Company's decisions to open offices in new markets are based on management's
review of demographic information, existing client needs, business growth
projections and the level of competition in the area. The Company recently
opened two additional offices in Southern California and expects to open two
offices in the metropolitan New York City area in 1999.
 
  Make Strategic Acquisitions. The Company believes that the multimedia
presentation and communication services industry is highly fragmented and
consists primarily of small companies that operate within limited geographical
areas. The Company believes that its industry offers substantial consolidation
opportunities. The Company has acquired three businesses since June 1, 1998 and
recently entered into non-binding letters of intent to acquire two additional
businesses. The Company seeks to acquire selected businesses in targeted
geographic markets and to expand the operations of acquired companies through
internal growth. The Company believes that its acquisitions to date have
allowed it to:
 
  . add new clients;
 
  . further develop its relationships with existing clients;
 
                                       37
<PAGE>
 
  . offer new services and capabilities; and
 
  . acquire experienced personnel.
 
See "--Recent and Potential Acquisitions."
 
  Develop and Maintain Strong Supplier Relationships. The Company currently has
distribution relationships with over 300 suppliers, including leading
communications technology, digital media hardware and software manufacturers
such as InFocus, NEC, Sony and PictureTel. The Company believes that its strong
relationships with suppliers have enabled the Company to attract and retain
clients by allowing it to offer a large selection of cutting-edge
communications equipment. The Company believes that it is able to negotiate
attractive pricing and volume discounts from suppliers because of its size and
position in the industry. The Company intends to continue to develop
relationships and obtain exclusive distribution agreements with companies that
are developing new technologies in order to ensure that its clients have access
to the latest technology at favorable prices.
 
  Focus on Staff Professional Development. The Company seeks to employ highly
qualified and trained sales and technical personnel in order to provide
superior service to its clients. The Company's sales staff regularly attends
manufacturer and industry sponsored training to obtain manufacturer
certification and expertise in the features and benefits of the components and
systems the Company sells and installs. The Company's engineering, project
management and installation technicians participate (both as instructors and
students) in manufacturer and industry certification programs for high-level
technical training in system design, installation procedures, and component
applications, service and maintenance. The Company's personnel also attend
internally developed training programs for design and engineering, sales skills
and presentation and proposal writing.
 
RECENT AND POTENTIAL ACQUISITIONS
 
  The Company has acquired three businesses since June 1998 and recently
entered into non-binding letters of intent to acquire two additional
businesses. The Company intends to continue to participate in the consolidation
of the multimedia presentation and communication industry as opportunities
arise.
 
  Recent Acquisitions. In June 1998, the Company acquired all of the
outstanding capital stock of B. Higginbotham Enterprises, Inc. Higginbotham is
an integrated systems business with five offices located in Houston, Dallas,
Irving, El Paso and Fort Worth, Texas. The Higginbotham acquisition enabled the
Company to expand its business into the Texas integrated systems market.
 
  The Company also acquired Alford Media Sales, Inc., an integrated audiovisual
systems business located in Dallas, Texas, in June 1998. The Alford acquisition
has enabled the Company to enhance its technical and service capabilities.
 
  In August 1998, the Company acquired substantially all of the assets of
Digital Networks Corporation, a computer networking equipment and systems
business. Pursuant to the acquisition agreement, the Company assumed management
of Digital's operations effective June 1, 1998. The Digital acquisition has
enabled the Company to expand its services to include computer networking
systems and sales.
 
 
                                       38
<PAGE>
 
  Potential Acquisitions. On August 23, 1998, the Company entered into a non-
binding letter of intent with Aurora Visual Systems with respect to the
Company's acquisition of substantially all of Aurora's assets. Aurora is a
portable systems business with locations in Seattle, Washington and Boise,
Idaho.
 
  On October 5, 1998, the Company entered into a non-binding letter of intent
to acquire all of the outstanding capital stock of Proline Industries, Inc.
Proline is a leading systems integration business with five locations in
Washington, Oregon and Northern California.
 
  Each of the Potential Acquisitions is subject to a number of contingencies,
including the execution of definitive purchase agreements, approval of the
Company's Board of Directors and completion of the sale of preferred stock to
finance the Potential Acquisitions. There can be no assurance that the Company
will be able to consummate these acquisitions on terms favorable to the
Company, or at all.
 
INTEGRATED SYSTEMS, PORTABLE EQUIPMENT AND SUPPORT SERVICES
 
  The Company provides its clients a single source for their multimedia
presentation and communication needs, from consultation through design,
engineering, procurement, installation, service and operations. The Company has
organized its design, engineering, sales, service and support professionals
into project teams to provide targeted expertise, application-specific
solutions and interdisciplinary experience in the key areas of integrated
systems, portable equipment and support services.
 
  Integrated Systems. The Company creates state-of-the-art presentation,
performance, production, conferencing and networked media systems integrated
into architectural environments, as well as portable systems, for business,
education and government clients. The Company works with developers,
contractors, facilities managers, architects, engineers and interior designers
as strategic partners in its clients' project teams.
 
  A typical integrated systems project begins with a consultation with the
Company's sales department. The Company assigns an account manager to the
client, who then meets with the client to determine the client's presentation
and communications needs, analyzes the physical space in which the system is to
be installed, and develops the initial system recommendations. The Company's
account manager works with the integrated systems group's designers, engineers
and project managers to produce a detailed set of plans and schematic layout of
the system. The account manager reviews the layout with the client and works
with the Company's procurement specialists to identify and purchase from major
manufacturers state-of-the-art audio, video, presentation or remote control
technology. The Company's engineering staff works directly with manufacturers
when the system requires a custom product or application. Finally, the
Company's project manager oversees the installation of the integrated system at
the client's site and trains the client to use the system. In most cases, the
client and the Company enter into a post-installation service and support
contract that covers system maintenance and repair.
 
    Presentation. The Company designs, engineers and integrates systems for
small or large group presentation of graphics, video and other data that allow
participants to access and exchange information in an interactive setting.
These systems include large screen display, speech reinforcement,
 
                                       39
<PAGE>
 
soundtrack/stereo playback and remote control operations of room environment
and audiovisual equipment. The Company's clients use these systems for
meetings, training and education, and sales and marketing presentations in
single or multiple locations. The Company designs systems for board rooms,
auditoriums, conference centers, customer briefing and demonstration centers,
classrooms, council chambers, public assembly areas and command and control
centers. For example, in an advanced distance learning application the Company
may create a classroom "studio" that includes audio equipment and cameras that
follow instructors and students, as well as videoconferencing equipment that
enables students in remote locations to participate in classroom activities.
 
    Performance. The Company designs, engineers and integrates audio and video
systems for theatrical, performing arts, sports and entertainment venues. These
systems include public address systems, stadium-size video displays, special
audio and video effects, wide-screen motion picture film systems, animated
displays, automated theatrical operations, and broadcast and closed-circuit
television systems. The Company's performance projects have included museums,
themed urban entertainment centers, virtual reality experiences, children's
interactive playspaces, 3-D theaters and high-end retail display for clients
such as Sony and Disney.
 
    Production. The Company supplies and integrates analog and digital video
origination, graphics design, post-production and distribution equipment and
systems for independent video producers, post-production companies and internal
corporate, government and educational communications departments. Novice or
professional video producers can take their projects from start to finish on a
single integrated system designed and implemented by the Company, whether these
projects involve videotape, CD-ROM, digital video disk (DVD), intranet or
internet applications. The Company believes that the gradual replacement of
conventional analog components with digital on-line broadcast-quality equipment
and non-linear editing systems will continue to create opportunities to
integrate systems with sequencing flexibility for efficient media delivery.
 
    Conferencing Systems. The Company develops conferencing systems that allow
multi-site, real-time interactive exchange of audio, video, document and
computer information. These systems range from simple desktop systems to
integrated conference room systems for meetings to complex business television
and distance learning applications. The Company's conferencing systems include
telephone, audio/graphic, H.320 video, computer data, integrated switched
digital network, H.323 local area network/wide area network or
internet/intranet capabilities. The Company develops conferencing technology
solutions for document and data sharing, business negotiations, planning and
design collaborations, strategic planning meetings, and marketing and sales
presentations.
 
    Networked Media Systems. The Company develops integrated media access and
retrieval systems for electronic delivery of audio and video information across
multi-site television and data networks. The Company's account managers and
engineers work with the client's information technology staff to develop
appropriate fiberoptic or traditional cabling plans for the transmission of
audio, video and digital information. The Company designs, engineers and
installs integrated local area and wide area networks with accompanying
bridging, routing, multiplexing and switching hardware. Media access and
retrieval systems include a media library in which all of the client's
equipment and educational content (whether in video or electronic format) is
located at a central "hub." Instructors or presenters at various sites can
review a catalog of programs in the media library and select programs to
present at their locations at a particular day and time.
 
                                       40
<PAGE>
 
    Portable Systems. The Company's portable systems team provides consulting
and procurement services with respect to small-format computer and video
presentation technology, including flat screen plasma displays, digital
projection systems, liquid crystal display monitors, panels and projectors,
videocassette recorders, speakerphones, carts and cables. The most common
portable systems sold by the Company are compact projecting systems that enable
presenters to make PowerPoint(TM) or other presentations in the office or on
the road directly from a laptop computer.
 
  In addition to custom integrated systems, the Company offers several
predesigned, prepackaged systems that can be delivered and installed quickly,
more efficiently and at favorable prices. These systems include display, audio
and control technologies, as well as audio and video conferencing capabilities.
 
  Portable Equipment. The Company distributes a full-line catalog from which
clients may purchase individual components. The Company's telemarketing staff
helps clients select the equipment that meets their pricing and performance
requirements.
 
  Support Services. The Company provides on-site and off-site maintenance,
repair and support services for integrated and portable display, audio, video,
control and network systems installed by the Company or others. Services
include full system diagnosis, system adjustment, component level electronic
repair and the provision of interim replacement equipment. All of the Company's
systems include a one-year warranty that covers basic system design. A number
of the Company's clients also elect to enter into extended service contracts
with terms from one to three years under which the Company's Service Center
staff provides manufacturer trained and certified maintenance and service. The
Company also provides full-time on-site support personnel who provide training
and orientation and presentation assistance including set-up and operation for
clients such as 3Com, Netscape and Cisco. The Company's support services group
also provides planning, trained technicians and state-of-the-art rental
equipment for short-term presentation needs. Although the Company's equipment
maintenance, repair and rental services have not contributed substantially to
its revenues to date, the Company plans to enhance its efforts to market those
services in the future.
 
RELATIONSHIPS WITH SUPPLIERS
 
  The Company believes that its strong relationships with suppliers have
enabled it to attract and retain clients by allowing it to offer a large
selection of cutting-edge and unique communications equipment. The Company has
distribution relationships with leading communications technology, digital
media hardware and software manufacturers, including:
 
    AMX                          Electrohome                 PictureTel
    Barco                        Extron                      Proxima
    Bose                         InFocus                     Sony
    Crestron                     NEC                         3M
 
  The Company maintains regional exclusive distribution agreements with certain
original equipment manufacturers. The Company is authorized to provide federal
government discounted pricing for Sony, Canon, Kodak, NEC, Panasonic and
PictureTel products, among others, for federal agency clients. Similarly, the
Company provides California, Arizona, Colorado and Texas
 
                                       41
<PAGE>
 
government discounted pricing for state agencies and educational institutions.
The Company's strategy is to continue to develop relationships with firms
developing new technologies to ensure that its clients have access to the
latest in communication technology at favorable prices. Approximately 15.6% of
the Company's revenue in 1997 and approximately 13.3% of the Company's revenue
in the six months ended June 30, 1998 were derived from the sale of products
supplied by InFocus, a leading manufacturer of portable presentation equipment.
However, the Company currently purchases and sells products from over 300
suppliers, including a number of other portable presentation equipment
suppliers.
 
CLIENTS
 
  The Company's business clients include technology, financial services,
telecommunications, consumer goods, manufacturing, energy, utilities, media and
publishing companies. The Company's educational clients include public and
private primary and secondary schools, colleges and universities. The Company
also develops and implements communications solutions for city, state and
federal government agencies, including public assembly, council chambers,
museum and operations control applications.
 
  The Company targets clients that are building new or renovating existing
facilities that will include production, presentation or performance spaces in
business, education and government. Management estimates that the Company
currently has approximately 2,000 clients, ranging from Fortune 500 companies
to sole proprietorships. Each year, a substantial portion of the Company's
revenue is derived from sales to a relatively small number of clients. During
1997 and the first six months of 1998, approximately 19% of the Company's
revenue for each period resulted from sales to our top 10 clients. The
identities of the Company's top clients change from period to period as we
complete our contracts with them. If the Company fails to replace the completed
contracts with new contracts of similar size, the Company's revenue and profits
may be adversely affected.
 
  The Company has completed approximately 1,000 integrated systems projects
since January 1996 for clients such as Netscape, Apple Computer, Cisco Systems,
3Com, Sun Microsystems, Silicon Graphics, Hewlett Packard, Compaq, Oracle,
Andersen Consulting, Fluor Daniel, Nike, Chevron, Franklin Resources, Pacific
Bell, Stanford University, University of California, University of Texas, NASA-
Ames Research Labs and the U.S. Department of Energy.
 
  The Company believes that its clients decide to purchase products and
services from the Company based on a variety of factors, the most important of
which is the Company's ability to provide a full range of consulting, design,
engineering, procurement, installation and support services. The Company's
clients also engage the Company because of its ability to offer a wide array of
state-of-the-art, market-leading products in all communications media.
 
MARKETING AND SALES
 
  Marketing. The Company uses a combination of direct mail, catalog, web
presence, in-house product seminars and demonstrations and participation in
industry trade show events (such as INFOCOMM SM) to raise client awareness of
the Company's products and services. The Company also advertises in the
regional business newspapers and publishes articles in industry publications
 
                                       42
<PAGE>
 
such as Systems Contractor News, Sound & Video Contractor, Sound &
Communication and the Communications Industries Report. The Company has
provided presentations and training for professional associations such as the
American Institute of Architects, the International Interior Design
Association, the Society for Marketing Professional Services, the International
Communications Industries Association and the National Systems Contractors
Association.
 
  Sales Force. The Company's sales force consists of an Executive Vice
President supported by Regional Sales Vice Presidents, Regional Sales Managers,
territory-based Account Managers and local Telemarketers. The Company's sales
force cultivates relationships with client staff in operations, facilities
planning, purchasing and information technology. The sales force also builds
relationships with developers, contractors, facilities managers, purchasing
agents, MIS managers, architects, engineers and interior designers. The
Company's sales force works with clients which have multiple locations to
develop communication standards for multimedia communication facilities and
systems.
 
  Training. The Company encourages and pays for its employees to participate in
self-paced, on-line industry training programs in the areas of sales, design
and installation. The Company is committed to having its entire sales,
operations and technical staff certified by the International Communications
Industries Association certification program. In addition, the Company works
with its suppliers to provide product-specific training and certification for
Company employees, both in the Company's offices and at the manufacturer's
locations. The Company has formulated a standard implementation program to
guide its employees through each integrated systems project. This program
includes needs assessment, conceptual design, infrastructure planning,
system/network design and implementation management. The Company believes that
this program enables its account managers and engineering staff to develop
comprehensive, cost-effective integrated systems for its clients.
 
COMPETITION
 
  No firm data exists on the size of the multimedia presentation and
communication services industry and the number and size of competitors within
the industry. However, the Company's management believes, based on its
experience in the industry, that the multimedia presentation and communication
services industry is highly competitive and highly fragmented. Although the
Company competes primarily with small, regional firms that offer more limited
services, some participants in the industry have national, full service
businesses and greater capabilities and financial resources. In addition, non-
traditional competitors who offer more mature and sophisticated products and
services (such as telecommunications, computing and energy management
companies) have begun to add multimedia presentation and communication services
and products to their existing technology products and services. The Company's
primary competitors are:
 
  . audiovisual equipment dealers;
 
  . companies that rent and sell audiovisual equipment, primarily in
    connection with staging services for trade shows and other corporate
    events;
 
  . independent design consulting firms;
 
  . electrical contractors;
 
  . manufacturers' sales and service divisions;
 
 
                                       43
<PAGE>
 
  . office superstores and consumer electronics chains; and
 
  . the in-house communications staffs of many clients and potential clients.
 
  Although the Company believes that most participants in the multimedia
presentation and communication services industry compete generally on the basis
of bid pricing, the Company promotes its ability to provide value-added
engineering and design services.
 
  The Company believes that the multimedia presentation and communication
services industry will become more consolidated in the future and, as a result,
may become more competitive. The Company could be materially adversely affected
if its competitors expand their integrated systems businesses, if new
competitors with greater resources enter the industry or if the Company's
clients or potential clients choose to service their multimedia presentation
and communication needs internally.
 
EMPLOYEES
 
  As of October 1, 1998, the Company had 325 full-time and 45 part-time and
temporary employees, including 71 in sales and marketing, 174 in engineering
and technical services, and 80 in corporate administration. The Company
believes that its employee relations are satisfactory and has never experienced
a work stoppage.
 
PROPERTIES
 
  The Company's sales and operations, administration and executive offices and
warehouse facilities are located in 15 leased facilities with an aggregate of
approximately 89,800 square feet in the following locations:

that expire on various dates through 2003. Certain of these leases include
renewal options. The Company's aggregate rental expense for the year ended

California, Oregon, Idaho and Washington; the Company anticipates that certain
of these facilities will be consolidated with the Company's existing offices
following the acquisitions. The Company believes that it will need to expand
its corporate headquarters facility to accommodate reasonably expected growth
and that its other facilities are adequate to meet its current needs. The
Company believes that it will be able to obtain suitable additional or
alternative space, as needed, on commercially reasonable terms.
 
LEGAL PROCEEDINGS
 
  The Company is not a party to any legal proceedings other than various claims
and lawsuits arising in the ordinary course of its business. Although the
ultimate legal and financial liability of the Company with respect to these
pending legal proceedings cannot be estimated with certainty, the Company
believes that such ultimate liability will not have a material adverse effect
on its business or financial condition.

                                       47
<PAGE>
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  Historically, the Company has not had a compensation committee or other
committee of the Board of Directors performing a similar function. Accordingly,
decisions concerning compensation of executive officers have been made by the
entire Board. The Board of Directors intends to establish a Compensation
Committee before the closing of this offering.
 
DIRECTOR COMPENSATION
 
  The Company has not historically compensated members of its Board of
Directors for serving as directors. The Company expects that, after this
offering, it will pay its non-employee directors in a manner and at a level
consistent with industry practice.
 
  In particular, the Company will grant non-employee directors non-qualified
stock options under the Company's 1998 Equity Participation Plan. Pursuant to
the terms of the 1998 Equity Participation Plan, the Company will grant to each
person who is a non-employee director as of the date of this offering a non-
qualified stock option to purchase 3,000 shares of common stock. After this
offering is completed, the Company will grant to each non-employee director a
non-qualified stock option to purchase 1,000 shares of common stock on the date
of each annual meeting of stockholders. The Company will grant to each non-
employee director, upon his or her initial appointment to the Board of
Directors, a stock option to purchase 3,000 shares of common stock pursuant to
the 1998 Equity Participation Plan. The price per share for shares subject to
these options will be equal to the fair market value per share of common stock
on the date the option is granted. Each option will have a 10-year term.
Options granted to non-employee directors will become exercisable in cumulative
annual installments of 25% over a four-year period, except that any option
granted to a non-employee director may by its terms become immediately
exercisable in full upon the retirement of the non-employee director in
accordance with Company policy.
 
EXECUTIVE COMPENSATION
 
  The following table sets forth information concerning compensation of the
Chairman, President and Chief Financial Officer of the Company and the other
highly compensated executive officers of the Company whose salary and incentive
compensation exceeded $100,000 for the year ended December 31, 1997 (the "Named
Executive Officers"). Dennis Kushner replaced Frank DiGirolamo as Vice
President, Operations in January 1998.

401(K) PROFIT SHARING PLAN
 
  The Company maintains a savings plan (the "401(k) Plan") qualified under
Section 401(a) and 401(k) of the Internal Revenue Code. Generally, all
employees of the Company who are at least 21 years of age and who have
completed 90 days of service are eligible to participate in the 401(k) Plan.
The Company makes matching contributions equal to 30% of a participant's salary
reductions, provided that the matching contributions made on behalf of
participant shall not exceed $500 for any plan year. The Company does not make
any discretionary profit sharing contributions under the 401(k) Plan.
 
                                       49
<PAGE>
 
  In connection with the Digital Networks Corporation acquisition, the Company
assumed a savings plan (the "Digital 401(k) Plan") qualified under Section
401(a) and 401(k) of the Internal Revenue Code. The Digital 401(k) Plan
generally provides that employees who are at least 19 years of age and who have
completed 90 days of services are eligible to participate in the plan. Matching
contributions are made at a percentage of a participant's salary reductions up
to 100% for any plan year. The Digital 401(k) Plan allows discretionary profit
sharing contributions on behalf of a participant based upon a pay formula that
equals the total amount of discretionary contributions multiplied by the ratio
of a participant's annual pay to the total annual pay to all participants.
 
1998 EQUITY PARTICIPATION PLAN
 
  The 1998 Equity Participation Plan of Intellisys Group, Inc. provides for the
grant to executive officers, other key employees, consultants and non-employee
directors of the Company of stock options, restricted stock, stock appreciation
rights, deferred stock, dividend equivalents, performance awards, stock
payments and other stock related benefits (collectively, the "Awards"). An
aggregate of 750,000 shares of common stock (or the equivalent in other equity
securities) may be issued under the 1998 Equity Participation Plan. The maximum
number of shares which may be subject to Awards granted under the 1998 Equity
Participation Plan to any individual in any year cannot exceed 200,000. Before
the closing of this offering, the Company plans to grant non-qualified stock
options to purchase an aggregate of     shares of common stock to certain
employees of the Company.
 
  Administration. Following the offering, the Compensation Committee of the
Board (the "Committee") will administer the 1998 Equity Participation Plan with
respect to grants to employees or consultants of the Company, and the full
Board will administer the 1998 Equity Participation Plan with respect to non-
qualified stock options granted to non-employee directors. Subject to the terms
and conditions of the 1998 Equity Participation Plan, the Board or Committee
has the authority to select the persons to whom Awards are to be made, to
determine the number of shares to be subject thereto and the terms and
conditions thereof, and to make all other determinations and to take all other
actions necessary or advisable for the administration of the 1998 Equity
Participation Plan.
 
  Nonqualified Stock Options ("NQSOs") provide for the right to purchase common
stock at a specified price which, except with respect to NQSOs intended to
qualify as performance-based compensation under Section 162(m) of the Code, may
be less than fair market value on the date of grant (but not less than par
value), and usually will become exercisable in installments after the grant
date. NQSOs may be granted for any term specified by the Committee.
 
  Incentive Stock Options ("ISOs"), are designed to comply with the provisions
of the Code and are subject to certain requirements contained in the Code,
including exercise prices equal to or exceeding the fair market value of the
common stock on the grant date and expiration ten years after the grant date.
ISOs may be subsequently modified to disqualify them from treatment as ISOs.
 
  Restricted Stock may be sold to participants at various prices (but not below
par value) and made subject to such restrictions as may be determined by the
Committee. Typically, restricted stock may be repurchased by the Company at the
original purchase price if the conditions or restrictions
 
                                       50
<PAGE>
 
are not met. In general, restricted stock may not be sold, or otherwise
transferred or hypothecated, until restrictions are removed or expire.
Purchasers of restricted stock, unlike recipients of options, will have voting
rights and will receive dividends before the time when the restrictions lapse.
 
  Deferred Stock may be awarded to participants, typically without payment of
consideration, but subject to vesting conditions based on continued employment
or on performance criteria established by the Committee. Like restricted stock,
deferred stock may not be sold, or otherwise transferred or hypothecated, until
vesting conditions are removed or expire. Unlike restricted stock, deferred
stock will not be issued until the deferred stock award has vested, and
recipients of deferred stock generally will have no voting or dividend rights
before the time when vesting conditions are satisfied.
 
  Stock Appreciation Rights ("SARs") may be granted in connection with stock
options or other Awards, or separately. SARs granted by the Committee in
connection with stock options or other Awards typically will provide for
payments to the holder based upon increases in the price of the Company's
common stock over the exercise price of the related option or other Awards, but
alternatively may be based upon criteria such as book value. Except as required
by Section 162(m) of the Code with respect to an SAR which is intended to
qualify as performance-based compensation, the Equity Plan does not place any
restrictions on the exercise of SARs or the amount of gain realizable
therefrom, although restrictions may be imposed by the Committee. The Committee
may elect to pay SARs in cash or in common stock or in a combination of both.
 
  Dividend Equivalents represent the value of the dividends per share paid by
the Company, calculated with reference to the number of shares covered by the
stock options, SARs or other Awards held by the participant.
 
  Performance Awards may be granted by the Committee on an individual or group
basis. Generally, these Awards will be based upon specific performance targets
and may be paid in cash or in common stock or in a combination of both.
Performance Awards may include "phantom" stock awards that provide for payments
based upon increases in the price of the Company's common stock over a
predetermined period. Performance Awards may also include bonuses which may be
granted by the Committee on an individual or group basis and which may be
payable in cash or in common stock or in a combination of both.
 
  Stock Payments may be authorized by the Committee in the form of shares of
common stock or an option or other right to purchase common stock as part of a
deferred compensation arrangement in lieu of all or any part of compensation,
including bonuses, that would otherwise be payable in cash to the key employee
or consultant.
 
STOCK OPTION AGREEMENTS
 
  Pursuant to written stock option agreements, the Company has issued options
to purchase an aggregate of 409,916 shares of Common Stock to certain executive
officers of the Company, at exercise prices equal to fair market value at the
date of the grant, as determined by the Board of Directors. Options to purchase
213,658 shares granted to certain executive officers of the Company in

                              CERTAIN TRANSACTIONS
 
  In 1996, the Company loaned $100,000 to Dupuis Group, L.L.C. pursuant to a
promissory note guaranteed by Donald J. Esters, the Company's Chairman,
President and Chief Financial Officer. Dupuis Group is a graphic design firm
that is wholly owned by Mr. Esters. The note is due on demand, and interest
accrues quarterly at the prime rate plus 0.75%. The Company paid Dupuis Group
$74,000 in 1997 and $18,000 for the six months ended June 30, 1998 for graphic
design services.
 
  The Company loaned $60,000 to Durand Communications, Inc. in 1997. Mr. Esters
is a member of the Board of Directors of Durand Communications. The loan has an
interest rate of 10% and is due and payable in December 1998.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have 6,162,859 shares of
common stock outstanding, including 43,078 shares of common stock expected to
be issued in connection with our acquisition of Proline Industries, Inc. and
122,619 shares of common stock to be issued by the Company upon automatic
conversion of subordinated convertible promissory notes issued or to be issued
in connection with the Aurora Visual Systems and Digital Networks Corporation
acquisitions. The shares sold in the offering (2,000,000 shares assuming no
exercise of the underwriters' over-allotment option) will be freely tradable
without restriction under the Securities Act, except for any such shares held
at any time by an "affiliate" of the Company, as such term is defined under
Rule 144 under the Securities Act.
 
  All shares other than the 2,000,000 shares sold in this offering were or will
be issued and sold by the Company in private transactions and may be publicly
sold only if registered under the Securities Act or sold in accordance with an
applicable exemption from registration, such as Rule 144. In general, under
Rule 144, as currently in effect, a person who has beneficially owned shares
for at least one year, including an "affiliate," as that term is defined in
Rule 144, is entitled to sell, within any three-month period, a number of
"restricted" shares that does not exceed the greater of one percent of the then
outstanding shares of Common Stock or the average weekly trading volume during
the four calendar weeks preceding such sale. Sales under Rule 144 are subject
to certain manner of sale limitations, notice requirements and the availability
of current public information about the Company. Rule 144(k) provides that a
person who is not deemed an "affiliate" and who has beneficially owned shares
for at least two years is entitled to sell such shares at any time under Rule
144 without regard to the limitations described above. Of the 4,069,781
remaining shares outstanding, affiliates hold 2,835,823 shares. Of the shares
owned by non-affiliates, 997,070 shares have been held by such non-affiliates
in excess of two years. See "Risk Factors--Shares Eligible for Future Sale."
 
  Any employee, officer, director, advisor or consultant to the Company who
purchased his or her shares pursuant to a written compensatory plan or contract
is entitled to rely on the resale provisions of Rule 701, which permits non-
affiliates to sell their Rule 701 shares without having to comply with the
public information, holding period, volume limitation or notice provisions of
Rule 144 and permits affiliates to sell their Rule 701 shares without having to
comply with Rule 144's holding period restrictions, in each case commencing 90
days after the Company becomes subject to the reporting requirements of Section
13 or 15(d) of the Securities Exchange Act of 1934.

  As of October 1, 1998, there were outstanding stock options to purchase an
aggregate of 409,916 shares of common stock, of which 238,746 were presently
exercisable or exercisable within 60 days. All outstanding stock options are
held by executive officers or employees of the Company. Following the offering,
the Company intends to file a registration statement on Form S-8 covering an
aggregate of 750,000 shares of common stock that have been reserved for
issuance under the Company's 1998 Equity Participation Plan and the 409,916
shares issuable upon exercise of options otherwise outstanding, thus permitting
the resale of such shares in the public market without restriction under the
Securities Act. Currently, no options have been granted under the 1998 Equity
Participation Plan. The Company intends to issue        non-qualified stock
options to purchase shares of common stock under the 1998 Equity Participation
Plan before the closing of this offering.
 
  The Company and certain executive officers and directors of the Company have
agreed with the underwriters, subject to certain exceptions, not to sell or
otherwise dispose of any shares of common stock of the Company for a period of
180 days from the consummation of this offering without the prior written
consent of the representatives of the underwriters.
 
  Before this offering, there has been no public market for the common stock.
The Company is unable to estimate the number of shares that may be sold in the
future by its existing stockholders or the effect, if any, that sales of shares
by such stockholders will have on the market price of the common stock
prevailing from time to time. Sales of substantial amounts of common stock by
existing stockholders could adversely affect prevailing market prices.
 
                          DESCRIPTION OF CAPITAL STOCK
 
  The following descriptions are qualified in their entirety by reference to
the Company's Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws, copies of which have been filed with the Securities and
Exchange Commission. The authorized capital stock of the Company consists of 30
million shares of common stock, $.01 par value per share, and 10 million shares
of preferred stock, $.01 par value per share.
 
COMMON STOCK
 
  Each holder of common stock is entitled to one vote per share in the election
of Directors and for all other purposes. There are no cumulative voting or
preemptive rights applicable to any shares of common stock. All shares of
common stock are entitled to participate pro rata in distributions and in such
dividends as may be declared by the Board of Directors out of funds legally
available therefor, subject to any preferential dividend rights of outstanding
shares of preferred stock. Subject to the prior rights of creditors, all shares
of common stock are entitled in the event of liquidation to participate ratably
in the distribution of all the remaining assets of the Company after
distribution in full of preferential amounts, if any, to be distributed to
holders of preferred stock. The rights, preferences and privileges of holders
of common stock are subject to, and may be adversely affected by, the rights of
any series of preferred stock which the Company may designate and issue in the
future. Each outstanding share of common stock is fully paid and non-
assessable.
 
                                       54
<PAGE>
 
PREFERRED STOCK
 
  The Company's preferred stock is divisible into and issuable in one or more
series. The rights and preferences of the different series may be established
by the Board of Directors without further action by the stockholders. The Board
of Directors is authorized with respect to each series to fix and determine,
among other things, (i) its dividend rate; (ii) its liquidation preference;
(iii) whether or not such shares will be convertible into, or exchangeable for,
any other securities; and (iv) whether or not such shares will have voting
rights, and, if so, the conditions under which such shares will vote as a
separate class.
 
  The Company believes that the Board of Directors' ability to issue preferred
stock on such a wide variety of terms will enable the preferred stock to be
used for important corporate purposes, such as financing acquisitions or
raising additional capital. However, were it inclined to do so, the Board of
Directors could issue all or part of the preferred stock with (among other
things) substantial voting power or advantageous conversion rights. Such stock
could be issued to persons deemed by the Board of Directors likely to support
current management in a contest for control of the Company, either as a
precautionary measure or in response to a specific takeover threat. The Company
expects to issue 1,058,489 shares of preferred stock in a private placement
prior to the closing of the offering.
 
REGISTRATION AND OTHER RIGHTS
 
  The Company entered into a Registration Rights Agreement, dated as of June
24, 1998 (the "Registration Rights Agreement"), with certain investors (each
individually, a "Holder," and collectively, the "Holders"). Pursuant to the
Registration Rights Agreement, if the Company proposes to register any of its
common stock under the Securities Act, the Holders have the right to register
such amount of their shares of common stock as they may request (a "piggyback
registration"), subject to certain limitations, and the Company will pay all
registration expenses in connection with such piggyback registration. Any
Holder's right to a piggyback registration will expire upon an effective
registration of such Holder's shares under the Securities Act or when the
shares of a Holder may be sold and transferred pursuant to Rule 144 or Rule 145
under the Securities Act. In addition, a Holder will lose the right to a
piggyback registration when such Holder ceases to own at least 0.5% of the then
outstanding shares of common stock of the Company. In connection with a Warrant
to Purchase Stock, dated as of June 29, 1998, between the Company and Sand Hill
Capital LLC ("Sand Hill"), the Company granted Sand Hill the same piggyback
registration rights which are subject to the terms of the Registration Rights
Agreement.
 
  Pursuant to an Investor Agreement, dated as of June 24, 1998 (the "Investor
Agreement"), among the Company, Donald Esters (the "Primary Investor") and
certain other investors (collectively, the "Minority Investors," and together
with the "Primary Investor," the "Investors"), the Investors have a preemptive
right to purchase any shares of common stock and securities convertible into
common stock that the Company proposes to sell, other than in connection with
an initial public offering or any subsequent registered public offering. In
addition, the Minority Investors have a right to participate, on the same terms
and conditions, in certain transfers of shares by the Primary Investor. If the
Primary Investor proposes to sell more than 80% of shares of common stock held
by him, then the Primary Investor has the right to require the Minority
Investors to participate in such transfer. The Investor Agreement will
terminate upon the consummation of this offering.
 
                                       55
<PAGE>
 
  The Company and certain of its stockholders are parties to stockholders'
agreements which (i) impose certain restrictions on transfer of shares of the
Company, (ii) require stockholders to offer to sell any shares first to the
Company and then to the other stockholders before offering such shares to a
third party, and (iii) require stockholders to take certain actions upon the
approval of a majority of the stockholders. These stockholders' agreements will
terminate upon completion of the offering.
 
CERTAIN CERTIFICATE OF INCORPORATION, BYLAW AND STATUTORY PROVISIONS AFFECTING
STOCKHOLDERS
 
  The Company's Board of Directors is divided into three classes with terms
expiring at the Company's annual meetings of stockholders in 1999, 2000 and
2001. Before completion of this offering, the Company intends to increase its
authorized number of directors from three to five and appoint two additional
Directors. Under the Delaware General Corporation Law ("DGCL"), directors
serving on a classified board can be removed only for cause.
 
  The Company's Amended and Restated Certificate of Incorporation and Amended
and Restated Bylaws provide that stockholder action can be taken only at an
annual or special meeting of stockholders and cannot be taken by written
consent in lieu of a meeting. The Certificate of Incorporation and Bylaws also
(i) provide that special meetings of the stockholders may be called only by a
resolution adopted by a majority of the Board of Directors of the Company or by
a committee of the Board of Directors which has been duly designated by the
Board of Directors and whose powers and authority include the power to call
such meetings; (ii) establish an advance notice procedure for stockholder
proposals; (iii) require that certain business combinations be approved by
supermajority vote; and (iv) reserve to the Board the exclusive right to change
the number of directors or to fill vacancies on the Board.
 
  The Company is a Delaware corporation and is subject to Section 203 of the
DGCL, which generally prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the time that the person became an interested
stockholder, unless (i) before such time the Board of Directors of the
corporation approved either the business combination or the transaction in
which the person became an interested stockholder; (ii) upon consummation of
the transaction that resulted in the stockholder becoming an interested
stockholder, the interested person owns at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding shares
owned by persons who are directors and also officers of the corporation and by
certain employee stock plans; or (iii) at or after such time the business
combination is approved by the Board of Directors of the corporation and
authorized at an annual or special meeting of stockholders, and not by written
consent, by the affirmative vote of at least 66 2/3% of the outstanding voting
stock of the corporation that is not owned by the interested stockholder. A
"business combination" generally includes mergers, asset sales and similar
transactions between the corporation and the interested stockholder, and other
transactions resulting in a financial benefit to the stockholder. An
"interested stockholder" is a person who, together with affiliates and
associates, owns 15% or more of the corporation's outstanding voting stock or
who is an affiliate or associate of the corporation and, together with his or
her affiliates and associates, has owned 15% or more of the corporation's
outstanding voting stock within three years.

  The provisions of the Certificate of Incorporation, Bylaws and DGCL described
above could make more difficult or discourage a proxy contest or acquisition of
control by a holder of a substantial block of the Company's stock or the
removal of the incumbent Board of Directors. Such provisions could also have
the effect of discouraging an outsider from making a tender offer or otherwise
attempting to obtain control of the Company, even though such an attempt might
be beneficial to the Company and its stockholders.
 
  The Company's Certificate of Incorporation and Bylaws also contain provisions
that (i) eliminate the personal liability of directors for monetary damages
resulting from breaches of fiduciary duty to the extent permitted by the DGCL
and (ii) indemnify directors and officers to the fullest extent permitted by
Section 145 of the DGCL, including in circumstances in which indemnification is
otherwise discretionary. The Company believes that these provisions are
necessary to attract and retain qualified directors and officers. The Company
has entered into indemnification agreements with its executive officers and
directors.
 
OTHER ATTRIBUTES OF THE COMPANY'S SECURITIES
 
  The Company is a corporation organized under the laws of Delaware. Generally,
the laws of the state of incorporation govern the corporate operations of a
corporation and the rights of its stockholders. Certain provisions of the
California Corporations Code become applicable to a corporation incorporated
outside of California, however, if (i) the corporation transacts business in
California and the average of its California property, payroll and sales
factors (as defined in the California Revenue and Taxation Code) with respect
to it is more than 50% during its latest fiscal year, (ii) more than one-half
of its outstanding voting securities are held of record by persons having
addresses in California and (iii) the corporation is not otherwise exempt. An
exemption is provided if the corporation has outstanding securities qualified
for trading as a national market security on the National Association of
Securities Dealers Automated Quotation System ("Nasdaq") if the corporation has
at least 800 record and nominee holders of its equity securities as of the
record date of its most recent annual meeting of stockholders.
 
  The Company has filed an application with the Nasdaq National Market for
quotation of its common stock. At present, most of the Company's activities
occur in California. The Company's existing stockholders with addresses in
California will own approximately 52.0% of the outstanding common stock
following the offering. Certain provisions of California corporate law may
apply to the Company, as described below, unless as a result of the offering
there are more than 800 holders of its equity securities as of the applicable
date.
 
  Except as discussed herein, provisions of California law which could be
applicable to the Company if the Company meets these tests and is not exempt
include, without limitation, those provisions relating to the stockholders'
right to cumulate votes in elections of directors (cumulative voting is
mandatory under California law), the stockholders' right to remove directors
without cause (which under California law is subject to the stockholders' right
to cumulate votes), the right of stockholders to call a special meeting (such
right is mandatory under California law if the requesting stockholder owns at
least 10% of the voting stock) and the Company's ability to indemnify its
officers, directors and employees (which is more limited in California than in
Delaware). Notwithstanding the foregoing, a corporation may provide for a
classified board of directors, or
 
                                       57
<PAGE>
 
eliminate cumulative voting, or both if it is a "listed corporation." A
"listed corporation" means a corporation with outstanding shares listed on the
New York Stock Exchange or the American Stock Exchange, or a corporation with
outstanding securities qualified for trading as a national market security on
Nasdaq if such corporation has at least 800 holders of its equity securities
as of the record date of its most recent annual meeting of stockholders.

  The Representatives have advised the Company that the Underwriters propose
to offer the shares of common stock to the public at the public offering price
set forth on the cover page of this prospectus and to certain dealers at such
price less a concession not in excess of $  per share, of which $  may be
reallowed to other dealers. After the public offering, the public offering
price, concession and reallowance to dealers may be reduced by the
Representatives. No such reduction shall change the amount of proceeds to be
received by the Company as set forth on the cover page of this prospectus.
 
  The Company has granted the Underwriters an option, exercisable during the
45-day period after the date of this prospectus, to purchase up to 300,000
additional shares of common stock at the public offering price, less the
underwriting discounts and commissions set forth on the cover page of this
prospectus. To the extent the Underwriters exercise the option, each of the
Underwriters will have a firm commitment to purchase approximately the same
percentage of such additional shares that the number of shares of common stock
to be purchased by it shown in the above table represents as a percentage of
the common stock offered hereby. If purchased, such additional shares will be
sold by the Underwriters on the same terms as those on which the common stock
offered hereby are being sold.
 
  The Underwriting Agreement contains certain covenants of indemnity among the
Underwriters and the Company against certain civil liabilities, including
liabilities under the Securities Act.

  Pursuant to the terms of the Lock-up Agreements, the executive officers and
directors and certain stockholders of the Company have agreed with the
Representatives that, until 180 days after the consummation of this offering,
they will not, directly or indirectly, sell, contract to sell, make any short
sale, pledge or otherwise dispose of any shares of common stock or securities
exchangeable for or convertible into shares of common stock, exclusive of
securities purchased in connection with this offering or in the public trading
market, without the prior written consent of the Representatives. Subject to
certain exceptions, the Company has also agreed until 180 days after the
closing date of this offering not to issue, offer, sell, purchase or otherwise
dispose of any shares of the Company's common stock or any other securities
convertible into or exchangeable for common stock or any other equity
security, except with the prior written consent of the Representatives. See
"Shares Eligible for Future Sale."
 
  The Representatives have advised the Company that the Underwriters do not
intend to confirm sales to any account over which they exercise discretionary
authority.
 
  At the closing of this offering, the Company will sell to the
Representatives, at a price of $.01 each, warrants to purchase up to 100,000
shares of common stock. Each warrant will be exercisable for a four-year
period, commencing one year from the date of this prospectus, at an exercise
price equal to $   per share (120% of the public offering price of the
shares). The warrants will contain anti-dilution provisions providing for
appropriate adjustments in any recapitalization, reclassification, stock
dividend, stock split or similar transaction by the Company. The warrants do
not entitle the Representatives to any rights as a stockholder of the Company
until the Representatives exercise the warrants.
 
  The Company has granted certain demand and piggyback registration rights for
the Common Stock underlying the warrants. On one occasion, at the
Representatives' request, at any time during the four-year period commencing
one year after the date of this prospectus, the Company will prepare and file
a new registration statement permitting the sale of the warrants and/or
underlying securities and use its best efforts to keep the registration
statement effective under the Securities Act for a nine month period following
the effective date. The Company will bear the cost of such registration
statement. If the Company files an equity offering registration statement
under the Securities Act at any time during the six-year period following the
date of this prospectus, the Company will, subject to certain exceptions,
include in such registration statement all or part of the underlying
securities at the request of the warrant holder. The warrants are not
transferable by the Representatives other than to employees and affiliates of
the Representatives.
 
  During and after the offering, the Underwriters may purchase and sell the
common stock in the open market. These transactions may include overallotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the offering. The Underwriters also may impose a
penalty bid, whereby selling concessions allowed to syndicate members of other
broker-dealers in respect of the shares of common stock sold in the offering
for their account may be reclaimed by the syndicate if such shares are
repurchased by the syndicate in stabilizing or covering transactions. These
activities may stabilize, maintain or otherwise affect the market price of the
common stock which may be higher than the price that might otherwise prevail
in the open market.

  There has been no public market for the common stock. The Public Offering
Price was determined by negotiations between the Company and the
Representatives. Among the factors considered in determining the Public
Offering Price were prevailing market conditions, the market values of publicly
traded companies that the Underwriters believed to be somewhat comparable to
the Company, the demand for the shares and for similar securities of publicly
traded companies that the Underwriters believed to be somewhat comparable to
the Company, the future prospects of the Company and its industry in general,
certain other financial and operating information of the Company in recent
periods, and other factors deemed relevant. There can be no assurance that the
prices at which the shares will sell in the public market after the offering
will not be lower than the Price to Public.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Stockholders Intellisys Group, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Intellisys
Group, Inc. and subsidiary (the Company) as of December 31, 1996 and 1997, and
the related consolidated statements of income, stockholders' equity, and cash
flows for each of the years in the three-year period ended December 31, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Intellisys
Group, Inc. and subsidiary as of December 31, 1996 and 1997, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1997, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       DECEMBER 31, 1995, 1996, AND 1997
                 (ALL AMOUNTS IN THOUSANDS, EXCEPT SHARE DATA)
 (INFORMATION AS OF JUNE 30, 1998, AND FOR THE SIX-MONTH PERIODS ENDED JUNE 30,
                          1997 AND 1998, IS UNAUDITED)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
(a) Description of Business
 
  The accompanying consolidated financial statements include the accounts of
Intellisys Group, Inc., formerly EISI, and its wholly owned subsidiary,
Educational Industrial Sales, Inc. (the Subsidiary), collectively "the
Company." The Company sells, designs, installs, and services multimedia
presentation and communication technology systems to corporations, government
agencies, and educational institutions.
 
  All significant intercompany balances and transactions have been eliminated
in consolidation.
 
(b) Revenue Recognition
 
  The Company recognizes revenue on installation sales using the percentage-of-
completion method. Revenue is recognized based on the percentage that costs to
date bear to total estimated costs. Losses expected to be incurred are recorded
when such losses are known. Product sales are recognized as revenue upon
shipment.
 
  The Company bills customers for services at intervals that coincide with the
completion of certain project phases. As of December 31, 1996 and 1997 and June
30, 1998, accounts receivable included unbilled amounts of $1,824, $2,911, and
$3,820, respectively.
 
  The Company sells maintenance contracts for new and existing multimedia
equipment installations. These contracts cover labor, parts, and materials and
are recognized as revenue using the straight-line method over the life of the
contract. The cost of the maintenance contract depends on the level of service
required by the customer. Revenue from these contracts has not been material.
 
(c) Property and Equipment
 
  Property and equipment are recorded at cost. Depreciation is calculated using
the straight-line method over the estimated useful lives of the assets, which
range from three to seven years. Leasehold improvements are amortized over the
shorter of the lease term or estimated useful life of the asset.
 
(d) Inventories
 
  Inventories consist primarily of finished goods and are valued at the lower
of cost (first in, first out) or market.
 
(e) Intangible Assets
 
  Intangible assets consist primarily of goodwill and covenants not to compete
arising from the application of purchase accounting. Goodwill is amortized on a
straight-line basis over its estimated
 
                                      F-7

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
useful life of 30 to 40 years. Covenants not to compete are amortized on a
straight-line basis over the life of the agreement.
 
(f) Impairment of Long-Lived Assets
 
  The Company periodically reviews its long-lived assets and certain
identifiable intangible assets for impairment. If events or changes indicate
that the carrying amount of an asset is not recoverable from expected
undiscounted cash flows, the Company will reduce the asset to its fair value.
 
(g) Fair Value of Financial Instruments
 
  The fair value of cash, accounts receivable, accounts payable and accrued
expenses approximates carrying value because of the short-term maturity of
those instruments. Although no quoted market prices are available and a portion
is due from a related party, the Company believes the fair value of the notes
receivable approximates the carrying value. The fair value of the Company's
long-term indebtedness is estimated based on the current rates offered to the
Company for debt of the same remaining maturities and approximates carrying
value.
 
(h) Stock-Based Compensation
 
  The Company has elected to follow Accounting Principles Board (APB) Opinion
No. 25, Accounting for Stock Issued to Employees, and related interpretations
in accounting for its employee stock options. Under APB Opinion No. 25, no
compensation expense is recognized when the exercise price of options equals
the fair value market price of the underlying stock on the date of grant. The
Company has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation.
 
(i) Income Taxes
 
  The Company accounts for income taxes using the asset and liability method.
Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
(j) Use of Estimates
 
  The Company's management has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent assets and liabilities to prepare these consolidated financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
(k) Concentration of Credit Risk
 
  The Company grants credit to its customers located in the western United
States, primarily in California. The Company's ability to collect the amounts
due from its customers is affected by economic conditions in its industry and
the geographical area in which it conducts business. Accounts receivable from
the Company's customers are generally due within 30 days and are subject to
credit risk. The Company monitors extensions of credit and records an allowance
for doubtful accounts based on its historical experience and management's
assessment of collectibility of specific accounts.
 
(l) Per Share Data
 
  The Company presents basic and diluted earnings per share (EPS) in the
consolidated statements of income. Basic EPS excludes dilution and is computed
by dividing net income available to common stockholders by the weighted-average
number of shares outstanding for the period. Diluted EPS includes dilution and
is computed using the weighted-average number of common and dilutive potential
common shares outstanding during the period. The dilutive effect of stock
options is calculated using the treasury stock method.
 
(m) Unaudited Balances
 
  The accompanying unaudited financial statements include all adjustments
(consisting of only normal recurring adjustments) that management considers
necessary for a fair presentation of the financial position and results of
operations as of the date and for the periods indicated.
 
(2) EARNINGS PER SHARE
 
  For both basic and diluted earnings per share, net income as reported was
used in the computation. A reconciliation of shares used in the computation for
basic and diluted earnings per share is as follows (in thousands):

  Based on the Company's historical operating earnings, management believes it
is more likely than not that the Company will realize the benefit of the
deferred income tax assets recorded and, accordingly, has established no
valuation allowance. Certain factors beyond management's control can affect
future levels of taxable income and, therefore, no assurances can be given that
sufficient taxable income will be generated to fully realize recorded tax
benefits.
 
(11) PENSION BENEFITS
 
  The Company sponsors a 401(k) savings plan. All full-time employees over the
age of 21 are eligible after 90 days of employment. The Company matches 30% of
an employee's annual contribution up to a maximum of five hundred dollars.
During 1995, 1996 and 1997, the Company contributed $13, $24 and $26,
respectively, to the 401(k) plan.
 
(12) STOCK OPTIONS
 
  During 1996 and 1997, the Board of Directors agreed to issue nonqualified
stock options to certain employees. The exercise price of options granted must
be at least equal to the market value of such shares on the date of grant, as
determined by the Board of Directors. The options vest over 5 years and expire
10 years from the grant date.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company applies APB Opinion No. 25 in accounting for its stock options.
The exercise price for stock options granted to employees in 1996 and 1997
equaled the fair value of the Company's stock at the date of grant.
Accordingly, no compensation cost has been recognized for these stock options.
There were no stock options granted during 1995. Had compensation cost been
determined pursuant to SFAS No. 123, the Company's 1996 and 1997, net income
and earnings per share would have been reduced to the pro forma amounts
indicated below:

purchase method of accounting. The excess of the costs over the fair value of
the acquired assets was recorded as goodwill and is being amortized over 30

(d) Acquisition of Aurora Visual Systems
 
  In August 1998, the Company entered into a non-binding letter of intent to

of the loan agreement, the lender was granted warrants to purchase 45,507
shares of the Company's common stock with an exercise price of $6.72 per share.
The warrants expire on June 28, 2003. The fair value of these warrants of $189

                         NOTES TO FINANCIAL STATEMENTS
 (INFORMATION AS OF MARCH 31, 1998, AND FOR THE NINE-MONTH PERIODS ENDED MARCH
                        31, 1997 AND 1998, IS UNAUDITED)
 
(1) GENERAL INFORMATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
(a) Description of Business
 
  B. Higginbotham Enterprises, Inc. (the Company) operates in all phases of the
audio/visual business, including audio/visual sales, rental, service and
installation. The Company's clients are dispersed among various Fortune 500
corporations, schools, churches and government agencies throughout Texas.
 
(b) Inventories
 
  Inventories generally consist of audio/visual equipment, which are stated at
the lower of average cost or market. As the majority of equipment is ordered
for a specific job, the Company carries very little inventory stock held for
sale.
 
(c) Revenue Recognition
 
  Revenue from product sales is recognized upon delivery of product. Revenue
from audio/visual installation and service is recognized using the percentage
of completion method based on the amount of labor incurred. Rental income is
recognized when earned. Revenue from the sale and installation of products
accounted for approximately 85% of total revenue during the year ended June 30,
1997 and the period ended March 31, 1998 (unaudited), with audio/visual service
and rental revenues accounting for the remainder.
 
(d) Property and Equipment
 
  Property and equipment are stated at cost and are depreciated and amortized
using an accelerated method, which corresponds to the higher use of the assets
in the earlier part of their useful lives, over the following estimated useful
lives of the respective assets:
 
<TABLE>
      <S>                                                          <C>
      Furniture and fixtures......................................     7 years
      Automobile and trucks.......................................     5 years
      Leasehold improvements...................................... 31-39 years
      Equipment...................................................   5-7 years
      Rental equipment............................................     7 years
</TABLE>
 
(e) Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed of
 
  Long-lived assets and certain identifiable intangibles are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured by
the amount by which the carrying amount of the assets exceed the fair value of
the assets. Assets to be disposed of are reported at the lower of the carrying
amount or fair value less costs to sell.

                   NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
(f) Other Assets
 
  Other assets consist primarily of goodwill and deposits. Amortization of
goodwill is calculated using the straight-line method over an estimated useful
life of 15 years. Amortization expense for the year ended June 30, 1997 and the
nine months ended March 31, 1998 was $744 and $700 (unaudited), respectively.
 
(g) Income Taxes
 
  The Company accounts for income taxes under the asset and liability method.
Deferred tax assets and liabilities are recognized for the estimated future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
basis. Deferred tax assets and liabilities are measured using enacted tax rates
in effect for the year in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.
 
(h) Use of Estimates
 
  The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
(i) Marketing and Advertising Costs
 
  Costs related to marketing and advertising have been expensed as incurred.
 
(j) Unaudited Balances
 
  The accompanying unaudited financial statements include all adjustments
(consisting of only normal recurring adjustments) that management considers
necessary for a fair presentation of the financial position and results of
operations as of the date and for the periods indicated.
 
(2) PROPERTY AND EQUIPMENT

months ended March 31, 1998, respectively.
 
  The Company has made non-interest bearing advances to its sole stockholder.
It is expected that the remaining balance of these advances, $2,724 (unaudited)
at March 31, 1998, will be received in fiscal 1998.
 
  Due from (to) the sole stockholder represents non-interest bearing balances
resulting from advances made or received monthly.
 
(7) FAIR MARKET VALUE OF FINANCIAL INSTRUMENTS
 
  For certain of the Company's financial instruments, including receivables,
bank overdraft, accounts payable, and sales and payroll taxes payable, the
carrying values approximates fair values because of their short maturity. The
carrying value of borrowing under the revolving line of credit approximates
fair value because of the variable interest rate. The fair values of borrowings
under notes payable and long-term debt approximate carrying values due to
current interest rates.

(8) EMPLOYEE STOCK OWNERSHIP PLAN
 
  On July 1, 1996, the Company established an Employee Stock Ownership Plan
(ESOP) to enable eligible employees to acquire a proprietary interest in the
stock of the Company. Any employee who has completed six months of service and
is at least 20 and one-half years old is eligible to participate in the ESOP.
The Company accrued a contribution of $152,499 at June 30, 1997 based on a
percentage of eligible wages. The common stock was issued in April 1998.
 
(9) COMMITMENTS
 
  The Company was guarantor of a loan to the sole stockholder of approximately
$100,000 which was used to fund construction of a building which houses the
Company's office facilities. The sole stockholder refinanced the loan in July
1997, and the Company was released from its guarantee.
 
(10) SUBSEQUENT EVENTS
 
  In April 1998, Higginbotham filed a form 3115 with the IRS for an
"Application for Change in Accounting Method" to convert from the cash basis to
the accrual method for income tax purposes.
 
  In June 1998, Higginbotham was acquired by Intellisys Group, Inc. and the
Company filed a resolution to terminate the ESOP plan.

To the Board of Directors
Proline Industries, Inc.
Seattle, Washington
 
  We have audited the accompanying balance sheets of Proline Industries, Inc.
as of December 31, 1997 and 1996, and the related statements of operations,
stockholders' equity, and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Proline Industries, Inc. as of

flows for the years then ended in conformity with generally accepted accounting
principles.

 (INFORMATION AS OF JUNE 30, 1998, AND FOR THE SIX-MONTH PERIODS ENDED JUNE 30,
                          1997 AND 1998, IS UNAUDITED)
 
NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
Organization
 
  Proline Industries, Inc. ("Proline") sells audio-visual, video and computer
projection equipment. The majority of the Company's accounts are businesses
located in the State of Washington. The Company also has offices in Oregon and
California.
 
Revenue Recognition
 
  Product sales are recognized as revenue upon shipment.
 
Estimates
 
  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that effect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
Cash
 
  For purposes of the statements of cash flows, Proline considers all highly
liquid debt instruments purchased with a maturity of three months or less to be
cash equivalents.
 
  Proline had issued checks in excess of bank deposits of $286,521, $465,527,
and $459,644 at December 31, 1996 and 1997, and June 30, 1998, respectively.
These amounts are included with accounts payable.
 
  Cash paid for interest was approximately $455,000 and $335,000 for the years
ended December 31, 1996 and 1997, respectively, and $156,000 and $180,000 for
the six months ended June 30, 1997 and 1998, respectively. Cash paid for income
taxes was approximately $94,000 and $92,000 for the years ended December 31,
1996 and 1997, respectively, and $41,000 and $52,000 for the six months ended
June 30, 1997 and 1998, respectively.
 
  The Company occasionally has cash balances on deposit in excess of FDIC
insurance limits throughout the year.
 
Inventory
 
  Inventories are carried at the lower of cost (first-in, first-out) or market.
Certain vendor accounts payable are secured by inventory.

Income Taxes
 
  Proline accounts for income taxes under the asset and liability approach that
requires the recognition of deferred tax assets and liabilities for expected
future tax consequences of events that have been recognized in the financial
statements or tax returns. In estimating future tax consequences, Proline
generally considers all expected future events other than enactments of changes
in tax laws or rates.
 
Advertising
 
  Advertising costs are charged to operations when the advertising first takes
place. Advertising expense amounted to $117,816 and $77,437 in the years ended
December 31, 1996 and 1997, and $22,506 and $48,383 in the six months ended
June 30, 1997 and 1998, respectively.
 
Unaudited Balances
 
  The accompanying unaudited financial statements include all adjustments
(consisting of only normal recurring adjustments) that management considers
necessary for a fair presentation of the financial position and results of
operations as of the date and for the periods indicated.
 
NOTE 2. CORPORATE REORGANIZATION
 
  On January 1, 1997, the Company reorganized into two corporations: Proline
Industries, Inc. and Proline Audio Visual Rentals, Inc. ("Proline Audio"). The
Board of Directors effected this split by forming Proline Audio and
simultaneously declaring a dividend to Proline shareholders in the form of 500
shares of common stock in the newly formed corporation. This represented all of
the Proline Audio issued stock. Stockholders of record of Proline received one
share of Proline Audio common stock for every 90 shares of Proline stock held.
No gain or loss was recognized on this disposal of a portion of the Company's
business. This transaction has been accounted for as a spin-

January 1, 1997, representing the carrying value of the assets and liabilities
transferred at the spin-off date. Proline Audio consists principally of the
assets and related liabilities that had been used by Proline in its rental
operations. The cost of the rental fixed assets transferred at the time of the
transfer was $1,773,512 with a net book value of $1,227,254. The liabilities
transferred to Proline Audio consisted of a note payable to a bank in the
amount of $410,620 and a loan payable to Proline for $475,750.
 
NOTE 3. LEASE COMMITMENTS
 
  Proline leases office and warehouse space in various locations under
noncancelable leases. Proline's office lease for its headquarters is
cancelable each January 31, but the Company expects to maintain the lease
through its entire five-year term, so it is included in the lease commitment
table below.
 
  Proline Audio reimburses the Company for its allocable share of rental
costs.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
As permitted by Section 145 of the Delaware General Corporation Law (the
"DGCL"), the Company's Amended and Restated Certificate of Incorporation
includes a provision that eliminates the personal liability of its directors
for monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to the Company
or its stockholders; (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of the law; (iii)
pursuant to Section 174 of the DGCL; or (iv) for any transaction from which the
director derived an improper personal benefit.
 
In addition, the Amended and Restated Bylaws of the Company provide that (i)
the Company shall indemnify any person who was or is a party or is threatened
to be made a party to any action, suit or proceeding by reason of the fact that
he or she is or was a director or officer of the Company, or is or was serving
in certain capacities of other enterprises (including, for example,
subsidiaries of the Company) at the Company's request, including those
circumstances in which indemnification would otherwise be discretionary; (ii)
the Company may, in its discretion, indemnify employees and agents in those
circumstances where indemnification is not required by law; (iii) expenses
incurred by a director or officer arising from a threatened or pending action,
suit or proceeding shall be paid by the Company in advance of final disposition
of the action upon receipt of an undertaking by or on behalf of such director
or officer to repay such amount if ultimately he is not entitled to
indemnification; and (iv) the rights conferred in the Bylaws are not exclusive
and the Company is authorized to enter into indemnification agreements with its
directors, officers and employees. The Bylaws permit the Company to maintain
director and officer liability insurance for its directors and officers whether
or not the Company would have the power or the obligation to indemnify them
against such liability under the indemnification provisions of the Bylaws.
 
                                      II-1

indemnify these officers and directors to the fullest extent permitted by the
DGCL.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

ITEM 17. UNDERTAKINGS
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
 
The undersigned registrant hereby undertakes that:
 
  (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
  (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.
 
  (3) It will provide to the Representatives, at the closing specified in the
  underwriting agreement, certificates in such denominations and registered
  in such names as required by the Representatives to permit prompt delivery
  to each purchaser.

                                   ARTICLE IV
                                   ----------

                                AUTHORIZED STOCK

     The total number of shares of all classes of stock which this Corporation
shall have authority to issue is Forty Million (40,000,000), consisting of
Thirty Million (30,000,000) shares of common stock, par value $.01 per share
(the "Common Stock"), and Ten Million (10,000,000) shares of preferred stock,
par value $.01 per share (the "Preferred Stock").

     The Board of Directors is authorized, subject to limitations prescribed by
law and the provisions of this Article IV, to provide for the issuance of the
shares of Preferred Stock in series, and by filing a certificate pursuant to the
applicable law of the State of Delaware, to establish from time to time the
number of shares to be included in each such series, and to fix the designation,
powers, preferences and rights of the shares of each such series and the
qualifications, limitations or restrictions thereof.
<PAGE>
 
     The authority of the Board with respect to each series shall include, but
not be limited to, determination of the following:

     (a) The number of shares constituting that series and the distinctive
designation of that series;

     (b) The dividend rate on the shares of that series, whether dividends shall
be cumulative, and, if so, from which date or dates, and the relative rights of
priority, if any, of payment of dividends on shares of that series;

     (c) Whether that series shall have voting rights, in addition to the voting
rights provided by law, and, if so, the terms of such voting rights;

     (d) Whether that series shall have conversion privileges, and, if so, the
terms and conditions of such conversion, including provision for adjustment of
the conversion rate in such events as the Board of Directors shall determine;

     (e) Whether or not the shares of that series shall be redeemable, and, if
so, the terms and conditions of such redemption, including the date or dates
upon or after which they shall be redeemable, and the amount per share payable
in case of redemption, which amount may vary under different conditions and at
different redemption dates;

     (f) Whether that series shall have a sinking fund for the redemption or
purchase of shares of that series, and, if so, the terms and amount of such
sinking fund;

     (g) The rights of the shares of that series in the event of voluntary or
involuntary liquidation, dissolution or winding up of this Corporation, and the
relative rights of priority, if any, of payment of shares of that series; and

     (h) Any other relative rights, preferences and limitations of that series.

     Dividends on outstanding shares of Preferred Stock shall be paid or
declared and set apart for payment before any dividends shall be paid or
declared and set apart for payment on the common shares with respect to the same
dividend period.

     If upon any voluntary or involuntary liquidation, dissolution or winding up
of this Corporation, the assets available for distribution to holders of shares
of Preferred Stock of all series shall be insufficient to pay such holders the
full preferential amount to which they are entitled, then such assets shall be
distributed ratably among the shares of all series of Preferred Stock in
accordance with the respective preferential amounts (including unpaid cumulative
dividends, if any) payable with respect thereto.

                                   DIRECTORS

                                   SECTION A

                              NUMBER OF DIRECTORS

     The business and affairs of this Corporation shall be managed by or under
the direction of the Board of Directors.  The number of directors shall not be
less than three (3) and the exact number of directors shall be fixed by the
Board of Directors by resolution.  Election of directors need not be by written
ballot.

                                   SECTION B

                          CLASSIFICATION OF THE BOARD

     The Board of Directors shall be and is divided into three classes,
designated Class I, Class II and Class III.  The number of directors in each
class shall be the whole number contained in the quotient arrived at by dividing
the authorized number of directors by three, and if a fraction is also contained
in such quotient then if such fraction is one-third (1/3), the extra directors
shall be a member of Class III and if the fraction is two-thirds (2/3), one of
the extra directors shall be a member of Class III and the other shall be a
member of Class II. Each director shall serve for a term ending on the date of
the third annual meeting following the annual meeting at which such director was
elected; provided, however, that the initial directors of this Corporation shall
each be assigned to a class at the time of their election, and the directors
assigned to Class I shall serve for a term ending on the 1999 annual meeting of
stockholders, directors appointed in Class II shall serve a term ending on the
date of the 2000 annual meeting of stockholders and the directors appointed to
Class III shall serve for a term ending on the date of the 2001 annual meeting
of stockholders.

     In the event of any increase or decrease in the number of directors (a)
each director then serving as such shall nevertheless continue as a director of
the class of which he is a member until the expiration of his current term, or
his prior death, retirement, resignation or removal, and (b) the newly created
or eliminated directorships resulting from such increase or decrease shall be
appointed by the Board of Directors to such class or classes as shall, so far as
possible, bring the number of directors in the respective classes into
conformity with the formula in this Article V, as applied to the new authorized
number of directors.

     Notwithstanding any of the foregoing provisions of this Article V, a
director shall hold office until the annual meeting of stockholders for the year
in which his term expires and until his successor is elected and qualified or
until his death, retirement, resignation or removal.  Should a vacancy occur or
be created, the remaining directors (even though less than a quorum) may fill
the vacancy for the full term of the class in which the vacancy occurs or is
created.

                                   SECTION C

                   NEWLY CREATED DIRECTORSHIPS AND VACANCIES

     Any vacancy on the Board of Directors resulting from death, resignation,
removal, disqualification or other cause, and newly created directorships
resulting from any increase in the number of directors on the Board of
Directors, shall be filled by the affirmative vote of a majority of the
remaining directors then in office (even though less than a quorum) or by the
sole remaining director.  Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the class of
directors in which the vacancy occurred or to which the new directorship is
apportioned, and until such director's successor shall have been elected and
qualified.  No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

                                   SECTION D

                            LIMITATION ON LIABILITY

     1.   Limitation On Liability.

     A director shall not be personally liable to this Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided that this Section shall not eliminate or limit the liability of a
director (i) for any breach of his duty of loyalty to this Corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of the law, (iii) under Section
174 of the General Corporation Law of Delaware, or (iv) for any transaction from
which the director derives an improper personal benefit.

     If the General Corporation Law of Delaware is hereafter amended to
authorize corporate action further limiting or eliminating the personal
liability of directors, then the liability of the director to this Corporation
shall be limited or eliminated to the fullest extent permitted by the General
Corporation Law of Delaware, as so amended from time to time.  Any repeal or
modification of this Section by stockholders of this Corporation shall be
prospective only, and shall not adversely affect any limitation on the personal
liability of a director of this Corporation existing at the time of such repeal
or modification.

     2.   Amendment or Repeal.

     Any repeal or modification of the foregoing provisions of this Section D
shall not adversely affect any right or protection hereunder of any person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

rescind the Bylaws of this Corporation.

                              STOCK NOT ASSESSABLE

liable for the debts, obligations or liabilities of this Corporation.  This
Amended and Restated Certificate of Incorporation shall not be subject to
amendment in this respect.

purposes may be called at any time by the Board of Directors, or by a majority

Directors which has been duly designated by the Board of Directors and whose
powers and authority, as provided in a resolution of the Board of Directors or
in the Bylaws of the Corporation, include the power to call such meetings, but
such special meetings may not be called by any other person or persons;
provided, however, that if and to the extent that any special meeting of
stockholders may be called by any other person or persons specified in any
provisions of the Certificate of Incorporation or any amendment thereto or any
certificate filed under Section 151(g) of the General Corporation Law of
Delaware, then such special meeting may also be called by the person or persons,
in the manner, at the times and for the purposes so specified.

                          ANNUAL AND SPECIAL MEETINGS

     No action required to be taken or which may be taken at any annual meeting
or special meeting of stockholders may be taken without a meeting, and the power
of stockholders to consent in writing, without a meeting, is specifically

of Dover, County of Kent, State of Delaware.

other places both within and without the State of Delaware as the Board of

require.

                            ------------------------

     Section 1.  PLACE OF MEETINGS. Meetings of stockholders shall be held at
any place within or outside the State of Delaware designated by the Board of
Directors. In the absence of any such designation, stockholders' meetings shall
be held at the principal executive office of the corporation.

     Section 2.  ANNUAL MEETING OF STOCKHOLDERS.

     (a) The annual meeting of stockholders shall be held each year on a date
and at a time designated by the Board of Directors.  At each annual meeting, (i)
directors shall be elected from the persons who are nominated in accordance with
the procedures set forth in Section 3.3 below and (ii) any proper business shall
be conducted which has been submitted in accordance with the procedures set
forth in paragraph (c) below.

     (b) Only proper business which has been submitted in accordance with the
following procedures shall be conducted at the annual meeting.  Submissions of
proper business to be conducted at the annual meeting may be made at such
meeting by or at the direction of the Board of Directors, by any committee or
persons appointed by the Board of Directors or by any stockholder of the
corporation who complies with the notice procedures set forth in this paragraph.
Such submissions of proper business by any stockholder shall be made pursuant to
timely notice in writing to the Secretary of the corporation.  To be timely, a
stockholder's notice shall be delivered to, or mailed and received at, the
principal executive offices of the corporation not less than 60 days prior to
the annual meeting; provided, however, that in the event that less than 75 days
notice or prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not
later than the close of business on the fifteenth day following the day on which
such notice of the date of the meeting was mailed or such public disclosure was
made, whichever first occurs.  Such stockholder's notice to the Secretary shall
set forth (i) a description of the proper business submitted for consideration
at the annual meeting and the reasons for conducting such business at the
meeting, and if such business includes a 

                                       1

proposal to amend the bylaws of the bylaws of the corporation, the language of
the proposed amendment, (ii) the name and record address of the stockholder
giving the notice, (iii) the class and number of shares of capital stock of the
corporation which are beneficially owned by the stockholder, and (iv) any
material interest of the stockholder in the business. No proper business shall
be conducted at the annual meeting unless submitted in accordance with the
procedures set forth herein. The Chairman of the Board shall, if the facts
warrant, determine and declare to the meeting that a submission of proper
business was not made in accordance with the foregoing procedure, and if he
should so determine, he shall so declare to the meeting and the defective
submission shall be disregarded.

     Section 3.  QUORUM; ADJOURNED MEETINGS AND NOTICE THEREOF. A majority of
the stock issued and outstanding and entitled to vote at any meeting of
stockholders, the holders of which are present in person or represented by
proxy, shall constitute a quorum for the transaction of business except as
otherwise provided by law, by the Certificate of Incorporation, or by these
Bylaws. A quorum, once established, shall not be broken by the withdrawal of
enough votes to leave less than a quorum and the votes present may continue to
transact business until adjournment. If, however, such quorum shall not be
present or represented at any meeting of the stockholders, a majority of the
voting stock represented in person or by proxy may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
shall be present or represented. The Chairman of the Board (or the President in
the absence of the Chairman of the Board) may adjourn the meeting from time to
time, whether or not there is such a quorum. At such adjourned meeting at which
a quorum shall be present or represented, any business may be transacted which
might have been transacted at the meeting as originally notified. If the
adjournment is for more than thirty days, or if after the adjournment a new
record date is fixed for the adjourned meeting, a notice of the adjourned
meeting shall be given to each stockholder of record entitled to vote thereat.

     Section 4.  VOTING. When a quorum is present at any meeting, the vote of
the holders of a majority of the stock having voting power present in person or
represented by proxy shall decide any question brought before such meeting,
unless the question is one upon which by express provision of the statutes, or
the Certificate of Incorporation, or these Bylaws, a different vote is required
in which case such express provision shall govern and control the decision of
such question.

     Section 5.  PROXIES. At each meeting of the stockholders, each stockholder
having the right to vote may vote in person or may authorize another person or
persons to act for him by proxy appointed by an instrument in writing subscribed
by such stockholder and bearing a date not more than three years prior to said
meeting, unless said instrument provides for a longer period. All proxies must
be filed with the Secretary of the corporation at the beginning of each meeting
in order to be counted in any vote at the meeting. Each stockholder shall have
one vote for each share of stock having voting power, registered in his name on
the books of the corporation on the record date set by the Board of Directors as
provided in Article VII, Section 6 hereof.

     Section 6.  SPECIAL MEETINGS. Special meetings of the stockholders, for any
purpose, or purposes, unless otherwise prescribed by statute or by the
Certificate of Incorporation, may be called at any time by the Board of
Directors, or by a majority of the members of the Board of Directors, or by a
committee of the Board of Directors which has been duly designated by the Board
of Directors and whose powers and authority, as provided in a resolution of the
Board of Directors or in the Bylaws of the corporation, include the power to
call such meetings, but such special meetings may not be called by any other
person or persons; provided, however, that if and to the extent that any special
meeting of stockholders may be called by any other person or persons specified
in any provisions of the Certificate of Incorporation or any amendment thereto
or any certificate filed under Section 151(g) of the 

                                       2
<PAGE>
 
General Corporation Law of Delaware, then such special meeting may also be
called by the person or persons, in the manner, at the times and for the
purposes so specified.

     Section 7.  NOTICE OF STOCKHOLDERS' MEETINGS. Whenever stockholders are
required or permitted to take any action at a meeting, a written notice of the
meeting shall be given which notice shall state the place, date and hour of the
meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called. The written notice of any meeting shall be given to
each stockholder entitled to vote at such meeting not less than ten nor more
than sixty days before the date of the meeting. If mailed, notice is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation.

     Section 8.  MAINTENANCE AND INSPECTION OF STOCKHOLDER LIST. The officer who
has charge of the stock ledger of the corporation shall prepare and make, at
least ten days before every meeting of stockholders, a complete list of the
stockholders entitled to vote at the meeting, arranged in alphabetical order,
and showing the address of each stockholder and the number of shares registered
in the name of each stockholder. Such list shall be open to the examination of
any stockholder, for any purpose germane to the meeting, during ordinary
business hours, for a period of at least ten days prior to the meeting, either
at a place within the city where the meeting is to be held, which place shall be
specified in the notice of the meeting, or, if not so specified, at the place
where the meeting is to be held. The list shall also be produced and kept at the
time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present.

     Section 9.  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING. No
action required to be taken or which may be taken at any annual meeting or
special meeting of the stockholders may be taken without a meeting, and the
power of stockholders to consent in writing, without a meeting, is specifically
denied.

                                  ARTICLE III.

                                   DIRECTORS
                                   ---------

     Section 1.  THE NUMBER OF DIRECTORS. The authorized number of directors
which shall constitute the whole Board shall be not less than three (3) nor more
than seven (7) directors. The exact number shall be determined from time to time
by resolution of the Board. Until otherwise determined by such resolution, the
Board shall consist of five (5) persons. Directors shall be elected at the
annual meeting of stockholders and each director shall serve until such person's
successor is elected and qualified or until such person's death, retirement,
resignation or removal. The directors need not be stockholders. Subject to the
rights, if any, of the holders of shares of Preferred Stock then outstanding, if
any, any director or the entire Board of Directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors except that (i) unless the certificate of
incorporation provides otherwise, if the corporation shall have a classified
board of directors, shareholders may effect such removal only for cause, and
(ii) so long as the corporation shall have cumulative voting in respect of the
election of directors, if less than the entire board is to be removed, no
director may be removed without cause if the votes cast against the removal of
the director would be sufficient to elect that person if then cumulatively voted
at an election of the entire Board of Directors or, if the corporation shall
have classes of directors, at an election of the class of directors of which
that person is a part.

     Section 2.  VACANCIES. Vacancies on the Board of Directors by reason of
death, resignation, retirement, disqualification, removal from office, or
otherwise, and newly created 

                                       3
<PAGE>
 
directorships resulting from any increase in the authorized number of directors
may be filled by a majority of the directors then in office, although less than
a quorum, or by a sole remaining director. The directors so chosen shall hold
office until the next annual election of directors and until their successors
are duly elected and shall qualify, unless sooner displaced. If there are no
directors in office, then an election of directors may be held in the manner
provided by statute. If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole Board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office. No decrease
in the number of directors constituting the Board of Directors shall shorten the
term of any incumbent director.

     Section 3.  NOTIFICATION OF NOMINATION. Subject to the rights, if any, of
the holders of shares of Preferred Stock then outstanding, if any, only persons
who are nominated in accordance with the following procedures shall be eligible
for election as directors. Nominations of persons for election to the Board of
Directors of the corporation may be made at a meeting of stockholders by or at
the direction of the Board of Directors, by any nominating or other committee or
person appointed by the Board, or by any stockholder of the corporation entitled
to vote for the election of directors at the meeting who complies with the
notice procedures set forth in this Section 3.3. Such nominations, other than
those made by or at the direction of the Board or by any nominating or other
committee or person appointed by the Board, shall be made pursuant to timely
notice in writing to the Secretary of the corporation. To be timely, a
stockholder's notice shall be delivered to, or mailed and received at, the
principal executive offices of the corporation not less than 60 days prior to
the meeting; provided, however, that in the event that less than 75 days notice
or prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not
later than the close of business on the fifteenth day following the day on which
such notice of the date of the meeting was mailed or such public disclosure was
made, whichever first occurs. Such stockholder's notice to the Secretary shall
set forth (a) as to each person whom the stockholder proposes to nominate for
election or reelection as a director, (i) the name, age, business address and
residence address of the person, (ii) the principal occupation or employment of
the person and his or her employment history for the most recent five years,
(iii) the class and number of shares of capital stock of the corporation which
are beneficially owned by the person, (iv) the consent of the person to serve as
a Director if so elected and (v) any other information relating to the person
that is required to be disclosed in solicitations for proxies for election of
directors pursuant to the rules and regulations under the Securities Exchange
Act of 1934, as amended; and (b) as to the stockholder giving the notice (i) the
name and record address of the stockholder and (ii) the class and number of
shares of capital stock of the corporation which are beneficially owned by the
stockholder; (iii) a description of all arrangements or understandings between
the stockholder and each nominee and any other person or persons pursuant to
which the nomination or nominations are to be made by the stockholder, (iv) a
representation that the stockholder is a holder of record of stock of the
corporation entitled to vote at such meeting and intends to appear in person or
by proxy at the meeting to nominate the person or persons specified in the
notices. The corporation may require any proposed nominee to furnish such other
information as may reasonably be required by the corporation to determine the
eligibility of such proposed nominee to serve as director of the corporation or
for use in the preparation of materials used for the solicitation of proxies for
the election of directors. The Chairman of the Board shall, if the facts
warrant, determine and declare to the meeting that a nomination was not made in
accordance with the foregoing procedure, and if he should so determine, he shall
so declare to the meeting and the defective nomination shall be disregarded.

     Section 4.  POWERS. The property and business of the corporation shall be

powers and authorities by these Bylaws expressly conferred upon them, the Board

things as are not by statute or by the Certificate of Incorporation or by these
Bylaws directed or required to be exercised or done by the stockholders.

     Section 5.  PLACE OF DIRECTORS' MEETINGS. The directors may hold their

request of two directors unless the Board consists of only one director; in
which case special meetings shall be called by the President or Secretary in
like manner or on like notice on the written request of the sole director.

     Section 8.  QUORUM. At all meetings of the Board of Directors a majority of
the authorized number of directors shall be necessary and sufficient to
constitute a quorum for the transaction of business, and the vote of a majority
of the directors present at any meeting at which there is a quorum, shall be the
act of the Board of Directors, except as may be otherwise specifically provided
by statute, by the Certificate of Incorporation or by these Bylaws. If a quorum
shall not be present at any meeting of the Board of Directors, the directors
present thereat may adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present. If only one
director is authorized, such sole director shall constitute a quorum.

     Section 9.  ACTION WITHOUT MEETING. Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, any action required or permitted
to be taken at any meeting of the Board of Directors or of any committee thereof
may be taken without a meeting, if all members of the Board or committee, as the
case may be, consent thereto in writing, and the writing or writings are filed
with the minutes of proceedings of the Board or committee.

     Section 10.  TELEPHONIC MEETINGS. Unless otherwise restricted by the
Certificate of Incorporation or these Bylaws, members of the Board of Directors,
or any committee designated by the Board of Directors, may participate in a
meeting of the Board of Directors, or any committee, by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and such participation in a
meeting shall constitute presence in person at such meeting.

     Section 11.  COMMITTEES OF DIRECTORS. The Board of Directors may, by
resolution passed by a majority of the whole Board, designate one or more
committees, each such committee to consist of one or more of the directors of
the corporation. The Board may designate one or more directors as alternate
members of any committee, who may replace any absent or disqualified member at
any meeting of the committee. In the absence or disqualification of a member of
a committee, the member or members thereof present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board 

                                       5
<PAGE>
 
of Directors to act at the meeting in the place of any such absent or
disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers
and authority of the Board of Directors in the management of the business and
affairs of the corporation, and may authorize the seal of the corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to amending the Certificate of Incorporation,
adopting an agreement of merger or consolidation, recommending to the
stockholders the sale, lease or exchange of all or substantially all of the

the authority to fix the compensation of directors. The directors may be paid
their expenses, if any, of attendance at each meeting of the Board of Directors
and may be paid a fixed sum for attendance at each meeting of the Board of
Directors or a stated salary as director. No such payment shall preclude any
director from serving the corporation in any other capacity and receiving
compensation therefor. Members of special or standing committees may be allowed
like compensation for attending committee meetings.

     Section 14.  INDEMNIFICATION.

     (a) The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines, ERISA excise taxes and amounts paid or to be paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     (b) The corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no such 

                                       6
<PAGE>
 
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the corporation unless and only to
the extent that the Court of Chancery of Delaware or the court in which such
action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case, such
person is fairly and reasonably entitled to indemnity for such expenses which
such Court of Chancery or such other court shall deem proper.

     (c) To the extent that a director, officer, employee or agent of the
corporation shall be successful on the merits or otherwise in defense, of any
action, suit or proceeding referred to in paragraphs (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

     (d) Any indemnification under paragraphs (a) and (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in paragraphs (a) and (b).  Such determination shall be
made (1) by the Board of Directors by a majority vote of the directors who are
not parties to such action, suit or proceeding, or (2) if there are no such
directors, or if such directors so direct, by independent legal counsel in a
written opinion, or (3) by the stockholders.

     (e) Expenses (including attorneys' fees) incurred in defending a civil,
criminal, administrative or investigative action, suit or proceeding may be paid
by the corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors in the manner provided in
paragraph (d) upon receipt of an undertaking by or on behalf of the director or
officer, employee or agent to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the corporation as
authorized in this Section 3.14.

     (f) The indemnification provided by this Section 3.14 shall not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any statute, provision in the Certificate of Incorporation or these Bylaws,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his official capacity and as to action in another capacity while
holding such office, and shall continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     (g) The Board of Directors may authorize, by a vote of a majority of a
quorum of the Board of Directors, the corporation to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under the provisions of this Section 3.14.

     (h) The corporation shall, to the fullest extent permitted by the General
Corporation Law of the State of Delaware, indemnify its directors, officers,
employees and agents against liabilities incurred in their capacities as such.

     (i) For the purposes of this Section 3.14, references to "the corporation"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would

                                       7
<PAGE>
 
have had power and authority to indemnify its directors, officers, and employees
or agents, so that any person who is or was a director, officer, employee or
agent of such constituent corporation, or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, limited liability company,
trust or other enterprise, shall stand in the same position under the provisions
of this Section with respect to the resulting or surviving corporation as he
would have with respect to such constituent corporation if its separate
existence had continued.

     (j) For purposes of this Section, references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan; and
references to "serving at the request of the corporation" shall include service
as a director, officer, employee or agent of the corporation which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants or beneficiaries; and
a person who acted in good faith and in a manner he reasonably believed to be in
the interest of the participants and beneficiaries of an employee benefit plan
shall be deemed to have acted in a manner "not opposed to the best interests of
the corporation" as referred to in this Section.

                                         --------  -------
to Incentive Stock Options, unless otherwise determined by the Administrator in
its discretion, a leave of absence, change in status from an employee to an
independent contractor or other change in the employee-employer relationship
shall constitute a Termination of Employment if, and to the extent that, such
leave of absence, change in status or other change interrupts employment for the
purposes of Section 422(a)(2) of the Code and the then applicable regulations
and revenue rulings under said Section.

                                  ARTICLE II.

                            SHARES SUBJECT TO PLAN

          2.1.  Shares Subject to Plan.
                ---------------------- 

                (a) The shares of stock subject to Awards shall be Common Stock,
     initially shares of the Company's Common Stock, par value $.01 per share.
     The aggregate number of such shares which may be issued upon exercise of
     such Options or rights or upon any such awards under the Plan shall not
     exceed 750,000 shares.  The shares of Common Stock issuable upon exercise
     of such Options or rights or upon any such awards may be either previously
     authorized but unissued shares or treasury shares.

                (b) The maximum number of shares which may be subject to Awards,

                                       6
<PAGE>
 
     granted under the Plan to any individual in any calendar year shall not
     exceed the Award Limit.  To the extent required by Section 162(m) of the
     Code, shares subject to Options which are canceled continue to be counted
     against the Award Limit.

          2.2.  Add-back of Options and Other Rights. If any Option, or other
                ------------------------------------ 
right to acquire shares of Common Stock under any other Award under the Plan,
expires or is canceled without having been fully exercised, or is exercised in
whole or in part for cash as permitted by the Plan, the number of shares subject
to such Option or other right but as to which such Option or other right was not
exercised prior to its expiration, cancellation or exercise may again be
optioned, granted or awarded hereunder, subject to the limitations of Section
2.1. Furthermore, any shares subject to Awards which are adjusted pursuant to
Section 11.3 and become exercisable with respect to shares of stock of another
corporation shall be considered cancelled and may again be optioned, granted or
awarded hereunder, subject to the limitations of Section 2.1. Shares of Common
Stock which are delivered by the Holder or withheld by the Company upon the
exercise of any Award under the Plan, in payment of the exercise price thereof
or tax withholding thereon, may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1. If any shares of Restricted Stock are
surrendered by the Holder or repurchased by the Company pursuant to Section 7.4
or 7.5 hereof, such shares may again be optioned, granted or awarded hereunder,
subject to the limitations of Section 2.1. Notwithstanding the provisions of
this Section 2.2, no shares of Common Stock may again be optioned, granted or
awarded if such action would cause an Incentive Stock Option to fail to qualify
as an incentive stock option under Section 422 of the Code.

                                 ARTICLE III.

                              GRANTING OF AWARDS

          3.1.  Award Agreement. Each Award shall be evidenced by an Award
                --------------- 
Agreement. Award Agreements evidencing Awards intended to qualify as 
performance-based compensation as described in Section 162(m)(4)(C) of the Code
shall contain such terms and conditions as may be necessary to meet the
applicable provisions of Section 162(m) of the Code. Award Agreements evidencing
Incentive Stock Options shall contain such terms and conditions as may be
necessary to meet the applicable provisions of Section 422 of the Code.

          3.2.  Provisions Applicable to Section 162(m) Participants.
                ---------------------------------------------------- 

                (a) The Committee, in its discretion, may determine whether an
     Award is to qualify as performance-based compensation as described in
     Section 162(m)(4)(C) of the Code.


                (b) Notwithstanding anything in the Plan to the contrary, the
     Committee may grant any Award to a Section 162(m) Participant, including
     Restricted Stock, the restrictions with respect to which lapse upon the
     attainment of performance goals which are related to one or more of the
     Performance Criteria and any performance or incentive award described in
     Article VIII that vests or becomes exercisable or payable upon the
     attainment of performance goals which are related to one or more of the

                                       7
<PAGE>
 
     Performance Criteria.

               (c)  To the extent necessary to comply with the performance-based
     compensation requirements of Section 162(m)(4)(C) of the Code, with respect
     to any Award granted under Articles VII and VIII which may be granted to
     one or more Section 162(m) Participants, no later than ninety (90) days
     following the commencement of any fiscal year in question or any other
     designated fiscal period or period of service (or such other time as may be
     required or permitted by Section 162(m) of the Code), the Committee shall,
     in writing, (i) designate one or more Section 162(m) Participants, (ii)
     select the Performance Criteria applicable to the fiscal year or other
     designated fiscal period or period of service, (iii) establish the various
     performance targets, in terms of an objective formula or standard, and
     amounts of such Awards, as applicable, which may be earned for such fiscal
     year or other designated fiscal period or period of service and (iv)
     specify the relationship between Performance Criteria and the performance
     targets and the amounts of such Awards, as applicable, to be earned by each
     Section 162(m) Participant for such fiscal year or other designated fiscal
     period or period of service.  Following the completion of each fiscal year
     or other designated fiscal period or period of service, the Committee shall
     certify in writing whether the applicable performance targets have been
     achieved for such fiscal year or other designated fiscal period or period
     of service.  In determining the amount earned by a Section 162(m)
     Participant, the Committee shall have the right to reduce (but not to
     increase) the amount payable at a given level of performance to take into
     account additional factors that the Committee may deem relevant to the
     assessment of individual or corporate performance for the fiscal year or
     other designated fiscal period or period of service.

               (d)  Furthermore, notwithstanding any other provision of the
     Plan, any Award which is granted to a Section 162(m) Participant and is
     intended to qualify as performance-based compensation as described in
     Section 162(m)(4)(C) of the Code shall be subject to any additional
     limitations set forth in Section 162(m) of the Code (including any
     amendment to Section 162(m) of the Code) or any regulations or rulings
     issued thereunder that are requirements for qualification as performance-
     based compensation as described in Section 162(m)(4)(C) of the Code, and
     the Plan shall be deemed amended to the extent necessary to conform to such
     requirements.

          3.3.  Limitations Applicable to Section 16 Persons. Notwithstanding
                --------------------------------------------
any other provision of the Plan, the Plan, and any Award granted or awarded to
any individual who is then subject to Section 16 of the Exchange Act, shall be
subject to any additional limitations set forth in any applicable exemptive rule
under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 of
the Exchange Act) that are requirements for the application of such exemptive
rule. To the extent permitted by applicable law, the Plan and Awards granted or
awarded hereunder shall be deemed amended to the extent necessary to conform to
such applicable exemptive rule.

          3.4.  Consideration. In consideration of the granting of an Award
                -------------
under the Plan, the Holder shall agree, in the Award Agreement, to remain in the
employ of (or to consult

                                       8
<PAGE>
 
for or to serve as an Independent Director of, as applicable) the Company or any
Subsidiary for a period of at least one year (or such shorter period as may be
fixed in the Award Agreement or by action of the Administrator following grant
of the Award) after the Award is granted (or, in the case of an Independent
Director, until the next annual meeting of stockholders of the Company).

          3.5.  At-Will Employment. Nothing in the Plan or in any Award
                ------------------
Agreement hereunder shall confer upon any Holder any right to continue in the
employ of, or as a Consultant for, the Company or any Subsidiary, or as a
director of the Company, or shall interfere with or restrict in any way the
rights of the Company and any Subsidiary, which are hereby expressly reserved,
to discharge any Holder at any time for any reason whatsoever, with or without
cause, except to the extent expressly provided otherwise in a written employment
agreement between the Holder and the Company and any Subsidiary.

                                  ARTICLE IV.

                       GRANTING OF OPTIONS TO EMPLOYEES,
                     CONSULTANTS AND INDEPENDENT DIRECTORS

          4.1.  Eligibility. Any Employee or Consultant selected by the
                -----------
Committee pursuant to Section 4.4(a)(i) shall be eligible to be granted an
Option. Each Independent Director of the Company shall be eligible to be granted
Options at the times and in the manner set forth in Section 4.5.

          4.2.  Disqualification for Stock Ownership. No person may be granted
                ------------------------------------
an Incentive Stock Option under the Plan if such person, at the time the
Incentive Stock Option is granted, owns stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the Company
or any then existing Subsidiary or parent corporation (within the meaning of
Section 422 of the Code) unless such Incentive Stock Option conforms to the
applicable provisions of Section 422 of the Code.

          4.3.  Qualification of Incentive Stock Options. No Incentive Stock
                ----------------------------------------
Option shall be granted to any person who is not an Employee.

          4.4.  Granting of Options to Employees and Consultants.
                ------------------------------------------------ 

                (a) The Committee shall from time to time, in its absolute
     discretion, and subject to applicable limitations of the Plan:

                    (i)  Determine which Employees are key Employees and select
          from among the key Employees or Consultants (including Employees or
          Consultants who have previously received Awards under the Plan) such
          of them as in its opinion should be granted Options;

                    (ii) Subject to the Award Limit, determine the number of
          shares to be subject to such Options granted to the selected key
          Employees or Consultants;

                                       9
<PAGE>
 
                    (iii)  Subject to Section 4.3, determine whether such
          Options are to be Incentive Stock Options or Non-Qualified Stock
          Options and whether such Options are to qualify as performance-based
          compensation as described in Section 162(m)(4)(C) of the Code; and

                    (iv)   Determine the terms and conditions of such Options,
          consistent with the Plan; provided, however, that the terms and
                                    --------  -------
          conditions of Options intended to qualify as performance-based
          compensation as described in Section 162(m)(4)(C) of the Code shall
          include, but not be limited to, such terms and conditions as may be
          necessary to meet the applicable provisions of Section 162(m) of the
          Code.

               (b)  Upon the selection of a key Employee or Consultant to be
     granted an Option, the Committee shall instruct the Secretary of the
     Company to issue the Option and may impose such conditions on the grant of
     the Option as it deems appropriate.

               (c)  Any Incentive Stock Option granted under the Plan may be
     modified by the Committee, with the consent of the Holder, to disqualify
     such Option from treatment as an "incentive stock option" under Section 422
     of the Code.

          4.5.  Granting of Options to Independent Directors.
                -------------------------------------------- 

          During the term of the Plan, each person who is an Independent
Director as of the date of the consummation of the initial public offering of
Common Stock automatically shall be granted (i) an Option to purchase three
thousand (3,000) shares of Common Stock (subject to adjustment as provided in
Section 11.3) on the date of such consummation and (ii) an Option to purchase
one thousand (1,000) shares of Common Stock (subject to adjustment as provided
in Section 11.3) on the date of each annual meeting of stockholders after the
consummation of such initial public offering at which the Independent Director
is reelected to the Board.  During the term of the Plan, a person who is
initially elected to the Board after the consummation of the initial public
offering of Common Stock and who is an Independent Director at the time of such
initial election automatically shall be granted (i) an Option to purchase three
thousand (3,000) shares of Common Stock (subject to adjustment as provided in
Section 11.3) on the date of such initial election and (ii) an Option to
purchase one thousand (1,000) shares of Common Stock (subject to adjustment as
provided in Section 11.3) on the date of each annual meeting of stockholders
after such initial election at which the Independent Director is reelected to
the Board.  Members of the Board who are employees of the Company who
subsequently retire from the Company and remain on the Board will not receive an
initial Option grant pursuant to clause (i) of the preceding sentence, but to
the extent that they are otherwise eligible, will receive, after retirement from
employment with the Company, Options as described in clause (ii) of the
preceding sentence.  All of the foregoing Option grants authorized by this
Section 4.5 are subject to stockholder approval of the Plan.

          4.6.  Options in Lieu of Cash Compensation.  Options may be granted
                ------------------------------------                         
under the Plan to Employees and Consultants in lieu of cash bonuses which would
otherwise be payable to

                                       10
<PAGE>
 
such Employees and Consultants and to Independent Directors in lieu of
directors' fees which would otherwise be payable to such Independent Directors,
pursuant to such policies which may be adopted by the Administrator from time to
time.

                                  ARTICLE V.

                               TERMS OF OPTIONS

          5.1. Option Price. The price per share of the shares subject to each
               ------------
Option granted to Employees and Consultants shall be set by the Committee;
provided, however, that such price shall be no less than the par value of a
- --------  -------
share of Common Stock, unless otherwise permitted by applicable state law, and:

               (a) in the case of Options intended to qualify as performance-
     based compensation as described in Section 162(m)(4)(C) of the Code, such
     price shall not be less than 100% of the Fair Market Value of a share of
     Common Stock on the date the Option is granted;

               (b) in the case of Incentive Stock Options such price shall not
     be less than 100% of the Fair Market Value of a share of Common Stock on
     the date the Option is granted (or the date the Option is modified,
     extended or renewed for purposes of Section 424(h) of the Code);

               (c) in the case of Incentive Stock Options granted to an
     individual then owning (within the meaning of Section 424(d) of the Code)
     more than 10% of the total combined voting power of all classes of stock of
     the Company or any Subsidiary or parent corporation thereof (within the
     meaning of Section 422 of the Code), such price shall not be less than 110%
     of the Fair Market Value of a share of Common Stock on the date the Option
     is granted (or the date the Option is modified, extended or renewed for
     purposes of Section 424(h) of the Code).

          5.2. Option Term. The term of an Option granted to an Employee or
               -----------
consultant shall be set by the Committee in its discretion; provided, however,
                                                            --------  -------
that, in the case of Incentive Stock Options, the term shall not be more than
ten (10) years from the date the Incentive Stock Option is granted, or five (5)
years from the date the Incentive Stock Option is granted if the Incentive Stock
Option is granted to an individual then owning (within the meaning of Section
424(d) of the Code) more than 10% of the total combined voting power of all
classes of stock of the Company or any Subsidiary or parent corporation thereof
(within the meaning of Section 422 of the Code). Except as limited by
requirements of Section 422 of the Code and regulations and rulings thereunder
applicable to Incentive Stock Options, the Committee may extend the term of any
outstanding Option in connection with any Termination of Employment or
Termination of Consultancy of the Holder, or amend any other term or condition
of such Option relating to such a termination.

<PAGE>
 
          5.3.  Option Vesting
                --------------

                (a) The period during which the right to exercise, in whole or
     in part, an Option granted to an Employee or a Consultant vests in the
     Holder shall be set by the Committee and the Committee may determine that
     an Option may not be exercised in whole or in part for a specified period
     after it is granted; provided, however, that, unless the Committee
                          --------  ------- 
     otherwise provides in the terms of the Award Agreement or otherwise, no
     Option shall be exercisable by any Holder who is then subject to Section 16
     of the Exchange Act within the period ending six months and one day after
     the date the Option is granted. At any time after grant of an Option, the
     Committee may, in its sole and absolute discretion and subject to whatever
     terms and conditions it selects, accelerate the period during which an
     Option granted to an Employee or Consultant vests.

                (b) No portion of an Option granted to an Employee or Consultant
     which is unexercisable at Termination of Employment or Termination of
     Consultancy, as applicable, shall thereafter become exercisable, except as
     may be otherwise provided by the Committee either in the Award Agreement or
     by action of the Committee following the grant of the Option.

                (c) To the extent that the aggregate Fair Market Value of stock
     with respect to which "incentive stock options" (within the meaning of
     Section 422 of the Code, but without regard to Section 422(d) of the Code)
     are exercisable for the first time by a Holder during any calendar year
     (under the Plan and all other incentive stock option plans of the Company
     and any parent or subsidiary corporation, within the meaning of Section 422
     of the Code) of the Company, exceeds $100,000, such Options shall be
     treated as Non-Qualified Options to the extent required by Section 422 of
     the Code.  The rule set forth in the preceding sentence shall be applied by
     taking Options into account in the order in which they were granted.  For
     purposes of this Section 5.3(c), the Fair Market Value of stock shall be
     determined as of the time the Option with respect to such stock is granted.

          5.4.  Terms of Options Granted to Independent Directors.  The price
                -------------------------------------------------            
per share of the shares subject to each Option granted to an Independent
Director shall equal 100% of the Fair Market Value of a share of Common Stock on
the date the Option is granted; provided, however, that the price of each share
                                --------  -------                              
subject to each Option granted to Independent Directors on the date of the
initial public offering of Common Stock shall equal the initial public offering
price (net of underwriting discounts and commissions) per share of Common Stock.
Options granted to Independent Directors shall become exercisable in cumulative
annual installments of 25% on each of the first, second, third and fourth
anniversaries of the date of Option grant and, subject to Section 6.6, the term
of each Option granted to an Independent Director shall be ten (10) years from
the date the Option is granted, except that any Option granted to an Independent
Director may by its terms become immediately exercisable in full upon the
retirement of the Independent Director in accordance with the Company's
retirement policy applicable to directors.  No portion of an Option which is
unexercisable at Termination of Directorship shall thereafter become
exercisable.

          5.5.  Substitute Awards.
                ----------------- 

          Notwithstanding the foregoing provisions of this Article V to the
contrary, in the case of an Option that is a Substitute Award, the price per
share of the shares subject to such Option may be less than the Fair Market
Value per share on the date of grant, provided, that the excess of:
                                      --------                     

                (a) the aggregate Fair Market Value (as of the date such
     Substitute Award is granted) of the shares subject to the Substitute Award;
     over

                (b) the aggregate exercise price thereof;  does not exceed the
     excess of;

                (c) the aggregate fair market value (as of the time immediately
     preceding the transaction giving rise to the Substitute Award, such fair
     market value to be determined by the Committee) of the shares of the
     predecessor entity that were subject to the grant assumed or substituted
     for by the Company; over

                (d) the aggregate exercise price of such shares.

                                  ARTICLE VI.

                              EXERCISE OF OPTIONS


          6.1.  Partial Exercise. An exercisable Option may be exercised in
                ----------------
whole or in part. However, an Option shall not be exercisable with respect to
fractional shares and the Administrator may require that, by the terms of the
Option, a partial exercise be with respect to a minimum number of shares.

          6.2.  Manner of Exercise. All or a portion of an exercisable Option
                ------------------     
shall be deemed exercised upon delivery of all of the following to the Secretary
of the Company or his or her office:

               (a)  A written notice complying with the applicable rules
     established by the Administrator stating that the Option, or a portion
     thereof, is exercised.  The notice shall be signed by the Holder or other
     person then entitled to exercise the Option or such portion of the Option;

               (b)  Such representations and documents as the Administrator, in
     its absolute discretion, deems necessary or advisable to effect compliance
     with all applicable provisions of the Securities Act and any other federal
     or state securities laws or regulations.  The Administrator may, in its
     absolute discretion, also take whatever additional actions it deems
     appropriate to effect such compliance including, without limitation,
     placing legends on share certificates and issuing stop-transfer notices to
     agents and registrars;

               (c)  In the event that the Option shall be exercised pursuant to
     Section

                                      13
<PAGE>
 
     11.1 by any person or persons other than the Holder, appropriate proof of
     the right of such person or persons to exercise the Option; and

                (d) Full cash payment to the Secretary of the Company for the
     shares with respect to which the Option, or portion thereof, is exercised.
     However, the Administrator, may in its discretion (i) allow a delay in
     payment up to thirty (30) days from the date the Option, or portion
     thereof, is exercised; (ii) allow payment, in whole or in part, through the
     delivery of shares of Common Stock which have been owned by the Holder for
     at least six months, duly endorsed for transfer to the Company with a Fair
     Market Value on the date of delivery equal to the aggregate exercise price
     of the Option or exercised portion thereof; (iii) allow payment, in whole
     or in part, through the surrender of shares of Common Stock then issuable
     upon exercise of the Option having a Fair Market Value on the date of
     Option exercise equal to the aggregate exercise price of the Option or
     exercised portion thereof; (iv) allow payment, in whole or in part, through
     the delivery of property of any kind which constitutes good and valuable
     consideration; (v) allow payment, in whole or in part, through the delivery
     of a full recourse promissory note bearing interest (at no less than such
     rate as shall then preclude the imputation of interest under the Code) and
     payable upon such terms as may be prescribed by the Administrator; (vi)
     allow payment, in whole or in part, through the delivery of a notice that
     the Holder has placed a market sell order with a broker with respect to

     the broker has been directed to pay a sufficient portion of the net
     proceeds of the sale to the Company in satisfaction of the Option exercise
     price, provided that payment of such proceeds is then made to the Company
            --------                                                          
     upon settlement of such sale; or (vii) allow payment through any
     combination of the consideration provided in the foregoing subparagraphs
     (ii), (iii), (iv), (v) and (vi).  In the case of a promissory note, the
     Administrator may also prescribe the form of such note and the security to
     be given for such note.  The Option may not be exercised, however, by
     delivery of a promissory note or by a loan from the Company when or where
     such loan or other extension of credit is prohibited by law.

modified, extended or renewed for purposes of Section 424(h) of the Code) such
Option to such Holder or (b) one year after the transfer of such shares to such
Holder.

          6.6.  Limitations on Exercise of Options Granted to Independent
                ---------------------------------------------------------
Directors. No Option granted to an Independent Director may be exercised to any

          7.3.  Rights as Stockholders. Subject to Section 7.4, upon delivery of
                ----------------------

surrendered to the Company without consideration, upon Termination of Employment
or, if applicable, upon Termination of Consultancy with the Company; provided,
                                                                     --------

Holder and the Company, at a cash price per share equal to the price paid by the
Holder for such Restricted Stock; provided, however, that the Committee in its
                                  --------  -------
sole and absolute discretion may provide that no such right of repurchase shall

ownership or control" (within the meaning of Treasury Regulation Section 1.162-
27(e)(2)(v) or any successor regulation thereto) of the Company or because of
the Holder's death or disability; provided, further, that, except with respect

be placed on certificates representing all shares of Restricted Stock that are
still subject to restrictions under Award Agreements, which legend or legends
shall make appropriate reference to the conditions imposed thereby.

          7.8.  Section 83(b) Election. If a Holder makes an election under
                ----------------------
Section 83(b) of the Code, or any successor section thereto, to be taxed with
respect to the Restricted Stock as of the date of transfer of the Restricted
Stock rather than as of the date or dates upon which the Holder would otherwise
be taxable under Section 83(a) of the Code, the Holder shall deliver a copy of
such election to the Company immediately after filing such election with the
Internal Revenue Service.

determined by the Committee. In making such determinations, the Committee shall
consider (among such other factors as it deems relevant in light of the specific

particular key Employee or Consultant.

                --------------------

                (a) Any key Employee or Consultant selected by the Committee may

     Stock, to be credited as of dividend payment dates, during the period
     between the date a Stock Appreciation Right, Deferred Stock or Performance
     Award is granted, and the date such Stock Appreciation Right, Deferred

                (b) Any Holder of an Option who is an Employee or Consultant

<PAGE>
 
     period between the date an Option is granted, and the date such Option is

     periods, regardless of whether such Option is subsequently exercised.

          8.4.  Stock Payments. Any key Employee or Consultant selected by the
                --------------
Committee may receive Stock Payments in the manner determined from time to time

rights as a Company stockholder with respect to such Deferred Stock until such
time as the Award has vested and the Common Stock underlying the Award has been
issued.

          8.6.  Term. The term of a Performance Award, Dividend Equivalent,

                           STOCK APPRECIATION RIGHTS

          9.1.  Grant of Stock Appreciation Rights. A Stock Appreciation Right
                ----------------------------------
may be granted to any key Employee or Consultant selected by the Committee. A
Stock Appreciation Right may be granted (a) in connection and simultaneously
with the grant of an Option, (b) with respect to a previously granted Option, or
(c) independent of an Option. A Stock Appreciation Right shall be subject to
such terms and conditions not inconsistent with the Plan as the Committee shall
impose and shall be evidenced by an Award Agreement.

          9.2.  Coupled Stock Appreciation Rights.
                ---------------------------------

                (a) A Coupled Stock Appreciation Right ("CSAR") shall be related
     to a particular Option and shall be exercisable only when and to the extent
     the related Option is exercisable.

                (b) A CSAR may be granted to the Holder for no more than the
     number of shares subject to the simultaneously or previously granted Option
     to which it is coupled.

                (c) A CSAR shall entitle the Holder (or other person entitled to
     exercise the Option pursuant to the Plan) to surrender to the Company
     unexercised a portion of the Option to which the CSAR relates (to the
     extent then exercisable pursuant to its terms) and to receive from the
     Company in exchange therefor an amount determined by multiplying the
     difference obtained by subtracting the Option exercise price from the Fair
     Market Value of a share of Common Stock on the date of exercise of the CSAR
     by the number of shares of Common Stock with respect to which the CSAR

                                       20
<PAGE>
 
     shall have been exercised, subject to any limitations the Committee may
     impose.

          9.3.   Independent Stock Appreciation Rights.
                 ------------------------------------- 

                 (a) An Independent Stock Appreciation Right ("ISAR") shall be
     unrelated to any Option and shall have a term set by the Committee.  An
     ISAR shall be exercisable in such installments as the Committee may
     determine.  An ISAR shall cover such number of shares of Common Stock as
     the Committee may determine; provided, however, that unless the Committee
                                  --------  -------                           
     otherwise provides in the terms of the ISAR or otherwise, no ISAR granted
     to a person subject to Section 16 of the Exchange Act shall be exercisable
     until at least six months have elapsed from (but excluding) the date on
     which the Option was granted.  The exercise price per share of Common Stock
     subject to each ISAR shall be set by the Committee.  An ISAR is exercisable
     only while the Holder is an Employee or Consultant; provided that the
     Committee may determine that the ISAR may be exercised subsequent to
     Termination of Employment or Termination of Consultancy without cause, or
     following a Change in Control of the Company, or because of the Holder's
     retirement, death or disability, or otherwise.

                 (b) An ISAR shall entitle the Holder (or other person entitled
     to exercise the ISAR pursuant to the Plan) to exercise all or a specified
     portion of the ISAR (to the extent then exercisable pursuant to its terms)
     and to receive from the Company an amount determined by multiplying the
     difference obtained by subtracting the exercise price per share of the ISAR
     from the Fair Market Value of a share of Common Stock on the date of
     exercise of the ISAR by the number of shares of Common Stock with respect
     to which the ISAR shall have been exercised, subject to any limitations the
     Committee may impose.

          9.4.   Payment and Limitations on Exercise.
                 ----------------------------------- 

                 (a) Payment of the amounts determined under Section 9.2(c) and
     9.3(b) above shall be in cash, in Common Stock (based on its Fair Market
     Value as of the date the Stock Appreciation Right is exercised) or a
     combination of both, as determined by the Committee.  To the extent such
     payment is effected in Common Stock it shall be made subject to
     satisfaction of all provisions of Section 6.3 above pertaining to Options.

                 (b) Holders of Stock Appreciation Rights may be required to
     comply with any timing or other restrictions with respect to the settlement
     or exercise of a Stock Appreciation Right, including a window-period
     limitation, as may be imposed in the discretion of the Committee.

Committee (or another committee or a subcommittee of the Board assuming the
functions of the Committee under the Plan) shall consist solely of two or more
Independent Directors appointed by and holding office at the pleasure of the
Board, each of whom is both a "non-employee director" as defined by Rule 16b-3
and an "outside director" for purposes of Section 162(m) of the Code.

                 ------------------------------
Committee to conduct the general administration of the Plan in accordance with
its provisions. The Committee shall have the power to interpret the Plan and the
Award Agreements, and to adopt such rules for the administration,
interpretation, and application of the Plan as are consistent therewith, to
interpret, amend or revoke any such rules and to amend any Award Agreement
provided that the rights or obligations of the Holder of the Award that is the
subject of any such Award Agreement are not affected adversely. Any such grant
or award under the Plan need not be the same with respect to each Holder. Any
such interpretations and rules with respect to Incentive Stock Options shall be
consistent with the provisions of Section 422 of the Code. In its absolute
discretion, the Board may at any time and from time to time exercise any and all
rights and duties of the Committee under the Plan except with respect to matters
which under Rule 16b-3 or Section 162(m) of the Code, or any regulations or
rules issued thereunder, are required to be determined in the sole discretion of
the Committee. Notwithstanding the foregoing, the full Board, acting by a
majority of its members in office, shall conduct the general administration of
the Plan with respect to Options and Dividend Equivalents granted to Independent
Directors.

          10.3.  Majority Rule; Unanimous Written Consent. The Committee shall
                 ----------------------------------------

the Committee.

          10.4.  Compensation; Professional Assistance; Good Faith Actions.
                 ---------------------------------------------------------
Members of the Committee shall receive such compensation,if any, for their
services as members as may be determined by the Board. All expenses and
liabilities which members of the Committee incur in connection with the
administration of the Plan shall be borne by the Company. The Committee may,
with the approval of the Board, employ attorneys, consultants, accountants,
appraisers, brokers, or other persons. The Committee, the Company and the
Company's officers and Directors shall be entitled to rely upon the advice,
opinions or valuations of any such persons. All actions taken and all
interpretations and determinations made by the Committee or the Board in good
faith shall be final and binding upon all Holders, the Company and all other
interested persons. No members of the Committee or Board shall be personally
liable for any action, determination or interpretation made in good faith with
respect to the Plan or Awards, and all members of the Committee and the Board
shall be fully protected by the Company in respect of any such action,
determination or interpretation.

                           MISCELLANEOUS PROVISIONS

          11.1.  Not Transferable. No Award under the Plan may be sold, pledged,
                 ----------------
assigned or transferred in any manner other than by will or the laws of descent
and distribution or, subject to the consent of the Administrator, pursuant to a
DRO, unless and until such Award has been exercised, or the shares underlying
such Award have been issued, and all restrictions applicable to such shares have
lapsed. No Award or interest or right therein shall be liable for the debts,
contracts or engagements of the Holder or his or her successors in interest or
shall be subject to disposition by transfer, alienation, anticipation, pledge,
encumbrance, assignment or any other means whether such disposition be voluntary
or involuntary or by operation of law by judgment, levy, attachment, garnishment
or any other legal or equitable proceedings (including bankruptcy), and any
attempted disposition thereof shall be null and void and of no effect, except to
the extent that such disposition is permitted by the preceding sentence.

          During the lifetime of the Holder, only he or she may exercise an
Option or other Award (or any portion thereof) granted to him under the Plan,
unless it has been disposed of with the consent of the Administrator pursuant to
a DRO.  After the death of the Holder, any exercisable portion of an Option or
other Award may, prior to the time when such portion becomes unexercisable under
the Plan or the applicable Award Agreement, be exercised by his or her personal
representative or by any person empowered to do so under the deceased Holder's
will or under the then applicable laws of descent and distribution.

          11.2.  Amendment, Suspension or Termination of the Plan. Except as
                 ------------------------------------------------
otherwise provided in this Section 11.2, the Plan may be wholly or partially
amended or otherwise modified, suspended or terminated at any time or from time
to time by the Administrator. However, without approval of the Company's
stockholders given within twelve months before or after the action by the
Administrator, no action of the Administrator may, except as provided in Section
11.3, increase the limits imposed in Section 2.1 on the maximum number of shares
which may be issued under the Plan. No amendment, suspension or termination of
the Plan shall, without the consent of the Holder alter or impair any rights or
obligations under any Award theretofore granted or awarded, unless the Award
itself otherwise expressly so provides. No Awards may be granted or awarded
during any period of suspension or after termination of the Plan, and in no
event may any Incentive Stock Option be granted under the Plan after the first
to occur of the following events:

                 (a) The expiration of ten years from the date the Plan is
     adopted by the Board; or

                 (b) The expiration of ten years from the date the Plan is
     approved by the Company's stockholders under Section 11.4.

          11.3.  Changes in Common Stock or Assets of the Company, Acquisition
                 -------------------------------------------------------------
or Liquidation of the Company and Other Corporate Events.
- -------------------------------------------------------- 

                 (a)  Subject to Section 11.3(d), in the event that any dividend
     or other distribution (whether in the form of cash, Common Stock, other
     securities, or other property), recapitalization, reclassification, stock
     split, reverse stock split, reorganization, merger, consolidation, split-
     up, spin-off, combination, repurchase, liquidation, dissolution, or sale,
     transfer, exchange or other disposition of all or substantially all of the
     assets of the Company, or exchange of Common Stock or other securities of
     the Company, issuance of warrants or other rights to purchase Common Stock
     or other securities of the Company, or other similar corporate transaction
     or event affects the Common Stock such that an adjustment is necessary in
     order to prevent dilution or enlargement of the benefits or potential
     benefits intended to be made available under the Plan or with respect to an
     Award, then the Administrator shall, in such manner as it may deem
     equitable, adjust any or all of:

                      (i)   the number and kind of shares of Common Stock (or
          other securities or property) with respect to which Awards may be
          granted or awarded (including, but not limited to, adjustments of the
          limitations in Section 2.1 on the maximum number and kind of shares
          which may be issued and adjustments of the Award Limit),

                      (ii)  the number and kind of shares of Common Stock (or
          other securities or property) subject to outstanding Awards, and

                      (iii) the grant or exercise price with respect to any
          Award.

                 (b)   Subject to Sections 11.3(b)(vii) and 11.3(d), in the
     event of any transaction or event described in Section 11.3(a) or any
     unusual or nonrecurring transactions or events affecting the Company, any
     affiliate of the Company, or the financial statements of the Company or any
     affiliate, or of changes in applicable laws, regulations, or accounting
     principles, the Administrator, in its sole and absolute discretion, and on
     such terms and conditions as it deems appropriate, either by the terms of
     the Award or by action taken prior to the occurrence of such transaction or
     event and either automatically or upon the Holder's request, is hereby
     authorized to take any one or more of the following actions whenever the
     Administrator determines that such action is appropriate in order to
     prevent dilution or enlargement of the benefits or potential benefits
     intended to be made available under the Plan or with respect to any Award
     under the Plan, to facilitate such transactions or events or to give effect
     to such changes in laws, regulations or principles:

                      (i)   To provide for either the purchase of any such Award
          for an amount of cash equal to the amount that could have been
          attained upon the exercise of such Award or realization of the
          Holder's rights had such Award been currently exercisable or payable
          or fully 

                                       24
<PAGE>
 
          vested or the replacement of such Award with other rights or property
          selected by the Administrator in its sole discretion;

                      (ii)  To provide that the Award cannot vest, be exercised
          or become payable after such event;

                      (iii) To provide that such Award shall be exercisable as
          to all shares covered thereby, notwithstanding anything to the
          contrary in Section 5.3 or 5.4 or the provisions of such Award;

                      (iv)  To provide that such Award be assumed by the
          successor or survivor corporation, or a parent or subsidiary thereof,
          or shall be substituted for by similar options, rights or awards
          covering the stock of the successor or survivor corporation, or a
          parent or subsidiary thereof, with appropriate adjustments as to the
          number and kind of shares and prices;

                      (v)   To make adjustments in the number and type of shares
          of Common Stock (or other securities or property) subject to
          outstanding Awards, and in the number and kind of outstanding
          Restricted Stock or Deferred Stock and/or in the terms and conditions
          of (including the grant or exercise price), and the criteria included
          in, outstanding options, rights and awards and options, rights and
          awards which may be granted in the future;

                      (vi)  To provide that, for a specified period of time
          prior to such event, the restrictions imposed under an Award Agreement
          upon some or all shares of Restricted Stock or Deferred Stock may be
          terminated, and, in the case of Restricted Stock, some or all shares
          of such Restricted Stock may cease to be subject to repurchase under
          Section 7.5 or forfeiture under Section 7.4 after such event; and

                      (vii) Notwithstanding any other provision of the Plan, in
          the event of a Change in Control, each outstanding Award shall, twenty
          (20) days prior to the effective date of the Change in Control,
          automatically become fully exercisable for all of the shares of Common
          Stock at the time subject to such rights and may be exercised for any
          or all of those shares as fully vested shares of Common Stock.

                 (c)  Subject to Sections 11.3(d), 3.2 and 3.3, the
     Administrator may, in its discretion, include such further provisions and
     limitations in any Award, agreement or certificate, as it may deem
     equitable and in the best interests of the Company.

                 (d)  With respect to Awards which are granted to Section 162(m)
     Participants and are intended to qualify as performance-based compensation
     under Section 162(m)(4)(C), no adjustment or action described in this
     Section 11.3 or in any 

                                       25
<PAGE>
 
     other provision of the Plan shall be authorized to the extent that such
     adjustment or action would cause such Award to fail to so qualify under
     Section 162(m)(4)(C), or any successor provisions thereto. No adjustment or
     action described in this Section 11.3 or in any other provision of the Plan
     shall be authorized to the extent that such adjustment or action would
     cause the Plan to violate Section 422(b)(1) of the Code. Furthermore, no
     such adjustment or action shall be authorized to the extent such adjustment
     or action would result in short-swing profits liability under Section 16 or
     violate the exemptive conditions of Rule 16b-3 unless the Administrator
     determines that the Award is not to comply with such exemptive conditions.
     The number of shares of Common Stock subject to any Award shall always be
     rounded to the next whole number.

                 (e)  Notwithstanding the foregoing, in the event that the
     Company becomes a party to a transaction that is intended to qualify for
     "pooling of interests" accounting treatment and, but for one or more of the
     provisions of this Plan or any Award Agreement would so qualify, then this
     Plan and any Award Agreement shall be interpreted so as to preserve such
     accounting treatment, and to the extent that any provision of the Plan or
     any Award Agreement would disqualify the transaction from pooling of
     interests accounting treatment (including, if applicable, an entire Award
     Agreement), then such provision shall be null and void. All determinations
     to be made in connection with the preceding sentence shall be made by the
     independent accounting firm whose opinion with respect to "pooling of
     interests" treatment is required as a condition to the Company's
     consummation of such transaction.

                 (f)  The existence of the Plan, the Award Agreement and the
     Awards granted hereunder shall not affect or restrict in any way the right
     or power of the Company or the shareholders of the Company to make or
     authorize any adjustment, recapitalization, reorganization or other change
     in the Company's capital structure or its business, any merger or
     consolidation of the Company, any issue of stock or of options, warrants or
     rights to purchase stock or of bonds, debentures, preferred or prior
     preference stocks whose rights are superior to or affect the Common Stock
     or the rights thereof or which are convertible into or exchangeable for
     Common Stock, or the dissolution or liquidation of the company, or any sale
     or transfer of all or any part of its assets or business, or any other
     corporate act or proceeding, whether of a similar character or otherwise.

          11.4.  Approval of Plan by Stockholders. The Plan will be submitted
                 --------------------------------
for the approval of the Company's stockholders within twelve months after the
date of the Board's initial adoption of the Plan. Awards may be granted or
awarded prior to such stockholder approval, provided that such Awards shall not
be exercisable nor shall such Awards vest prior to the time when the Plan is
approved by the stockholders, and provided further that if such approval has not
been obtained at the end of said twelve-month period, all Awards previously
granted or awarded under the Plan shall thereupon be canceled and become null
and void. In addition, if the Board determines that Awards other than Options or
Stock Appreciation Rights which may be granted to Section 162(m) Participants
should continue to be eligible to qualify as performance-based compensation
under Section 162(m)(4)(C) of the Code, the Performance 

                                       26
<PAGE>
 
Criteria must be disclosed to and approved by the Company's stockholders no
later than the first stockholder meeting that occurs in the fifth year following
the year in which the Company's stockholders previously approved the Performance
Criteria.

          11.5.  Tax Withholding. The Company shall be entitled to require
                 ---------------
payment in cash or deduction from other compensation payable to each Holder of
any sums required by federal, state or local tax law to be withheld with respect
to the issuance, vesting, exercise or payment of any Award. The Administrator
may in its discretion and in satisfaction of the foregoing requirement allow
such Holder to elect to have the Company withhold shares of Common Stock
otherwise issuable under such Award (or allow the return of shares of Common
Stock) having a Fair Market Value equal to the sums required to be withheld.

          11.6.  Loans. The Committee may, in its discretion, extend one or more
                 -----
loans to key Employees in connection with the exercise or receipt of an Award
granted or awarded under the Plan, or the issuance of Restricted Stock or
Deferred Stock awarded under the Plan. The terms and conditions of any such loan
shall be set by the Committee.

          11.7.  Forfeiture Provisions. Pursuant to its general authority to
                 ---------------------
determine the terms and conditions applicable to Awards under the Plan, the
Administrator shall have the right to provide, in the terms of Awards made under
the Plan, or to require a Holder to agree by separate written instrument, that
(a) (i) any proceeds, gains or other economic benefit actually or constructively
received by the Holder upon any receipt or exercise of the Award, or upon the
receipt or resale of any Common Stock underlying the Award, must be paid to the
Company, and (ii) the Award shall terminate and any unexercised portion of the
Award (whether or not vested) shall be forfeited, if (b)(i) a Termination of
Employment, Termination of Consultancy or Termination of Directorship occurs
prior to a specified date, or within a specified time period following receipt
or exercise of the Award, or (ii) the Holder at any time, or during a specified
time period, engages in any activity in competition with the Company, or which
is inimical, contrary or harmful to the interests of the Company, as further
defined by the Administrator or (iii) the Holder incurs a Termination of
Employment, Termination of Consultancy or Termination of Directorship for cause.

          11.8.  Effect of Plan Upon Options and Compensation Plans. The
                 --------------------------------------------------
adoption of the Plan shall not affect any other compensation or incentive plans
in effect for the Company or any Subsidiary. Nothing in the Plan shall be
construed to limit the right of the Company (a) to establish any other forms of
incentives or compensation for Employees, Directors or Consultants of the
Company or any Subsidiary or (b) to grant or assume options or other rights or
awards otherwise than under the Plan in connection with any proper corporate
purpose including but not by way of limitation, the grant or assumption of
options in connection with the acquisition by purchase, lease, merger,
consolidation or otherwise, of the business, stock or assets of any corporation,
partnership, limited liability company, firm or association.

          11.9.   Compliance with Laws. The Plan, the granting and vesting of
                  --------------------
Awards under the Plan and the issuance and delivery of shares of Common Stock
and the payment of money under the Plan or under Awards granted or awarded
hereunder are subject to compliance with all applicable federal and state laws,
rules and regulations (including but not limited to state and federal securities
law and federal margin requirements) and to such approvals by any listing,
regulatory or governmental authority as may, in the opinion of counsel for the
Company, be necessary or advisable in connection therewith. Any securities
delivered under the Plan shall be subject to such restrictions, and the person
acquiring such securities shall, if requested by the Company, provide such
assurances and representations to the Company as the Company may deem necessary
or desirable to assure compliance with all applicable legal requirements. To the
extent permitted by applicable law, the Plan and Awards granted or awarded
hereunder shall be deemed amended to the extent necessary to conform to such
laws, rules and regulations.

          11.10.  Titles. Titles are provided herein for convenience only and
                  ------
are not to serve as a basis for interpretation or construction of the Plan.

          11.11.  Governing Law. The Plan and any agreements hereunder shall be
                  -------------
administered, interpreted and enforced under the internal laws of the State of
California without regard to conflicts of laws thereof.


                                    *  *  *

Company shall, no later than 45 calendar days prior to the consummation of such
issuance, give written notice to each of the Investors of such proposed issuance
(the "Notice of Issuance"). Such Notice of Issuance shall describe the proposed
issuance, and contain an offer to each such Investor (other than the proposed
purchasers) that in the reasonable judgment of the Company is an Accredited
Investor, or who can provide the Company with an opinion of counsel, reasonably
satisfactory in form and substance to the Company, that the New Securities may
be sold to such Investor without registration under the Act or any state

the New Securities to be sold. Subject to the foregoing, if Common Stock is
being issued with other securities as a unit, each Accredited Offeree who
desires to accept such offer must purchase such unit in order for such
acceptance to be valid. If any such Accredited Offeree fails to accept such
offer by written notice within 30 calendar days after its receipt of the Notice
of Issuance, the Company may proceed with such proposed issuance, free of any
right on the part of such Accredited Offeree under this Section 2.1 in respect
thereof. This Section 2.1 shall not apply to: (a) issuances to employees or
pursuant to employee benefit or stock option plans, up to a maximum of 138,000

distributed or set aside to all holders of Common Stock on a per share
equivalent basis. Each of the parties hereto expressly waives any rights under

fractional shares and any fractional share shall be rounded up or down pursuant

                                         -----------------

proposed sale date and set forth: (i) the name of the Transferee and the number
of shares of Common Stock proposed to be transferred, (ii) the proposed amount

shares of Common Stock that such Tag-Along Stockholder wishes to include in such
Transfer to the Transferee, which number may exceed the total number of shares
proposed to be transferred but which may not exceed the total number of shares
beneficially owned (taking into account shares of Common Stock that may be
acquired

Stockholder. Upon the giving of a Tag-Along Notice, such Tag-Along Stockholder

been complied with in all respects, the Primary Investor shall have the right
for a 60-calendar-day period to Transfer the shares of Common Stock to the
Transferee on the Transferee Terms without further notice to any other party,

additional 60-calendar-day period and (ii) without again giving notice to the
appropriate Minority Investors of the proposed transfer and complying with the
requirements of this Article III.

notwithstanding, the Primary Investor agrees to use its reasonable good faith
efforts to seek to ensure that the applicable Transferee Terms contain (i)
representations, covenants or warranties as to ownership and authority to
sell, free of liens, claims and encumbrances the shares of Common Stock
proposed to be sold and (ii) for several, and not joint, liability, with
respect to the indemnification and comparable obligations contained within
such Transferee Terms.

the Transfer shall deliver certificates evidencing such shares, duly endorsed,

public offering under the Act.

          5.1.  Term.
                -----

                (a)  Unless earlier terminated as expressly provided herein,
this Agreement shall terminate five (5) years from the date of this Agreement.

                (b)  Notwithstanding the foregoing, this Agreement shall in

irreparably damaged and will not have an adequate remedy at law. Any such
Person shall, therefore, be entitled to injunctive relief, including specific

                   ------------------  
Period the Company proposes to file a registration statement under the
Securities Act with respect to a public offering of securities of the same type
as the Registrable Shares pursuant to a firm commitment underwritten offering
solely for cash for its own account (other than a registration statement (i) on
Form S-8 or any successor forms thereto, or (ii) filed solely in connection with
a dividend reinvestment plan or employee benefit plan of the Company or its
Affiliates) or for the

<PAGE>
 
account of any holder of securities of the same type as the Registrable Shares,
then the Company shall give written notice of such proposed filing to the
Holders at least 15 days before the anticipated filing date. Such notice shall
offer the Holders the opportunity to register such amount of Registrable Shares
as they may request (a "Piggyback Registration"). Subject to Section 2(b)
                        ----------------------

Registrable Shares with respect to which the Company has received written

Notwithstanding the foregoing, if the  managing underwriter or underwriters
participating in such offering advises the Holders in writing that the total
amount of securities requested to be included in such Piggyback Registration
exceeds the amount which can be sold in (or during the time of) such offering
without delaying or jeopardizing the success of the offering (including the
price per share of the securities to be sold), then the amount of securities to
be offered for the account of the Holders with respect thereto shall be reduced
(to zero if necessary) pro rata on the basis of the number of common stock
equivalents requested to be registered by each such Holder participating in such
offering.

          (c) Right to Abandon.  Nothing in this Section 2 shall create any
              ----------------                                             
liability on the part of the Company to the Holders if the Company in its sole
discretion should decide not to file a registration statement proposed to be
filed pursuant to Section 2(a) hereof or to withdraw such registration statement
subsequent to its filing and prior to the later of its effectiveness or the
release of the Registrable Shares for public offering by the managing
underwriter, in the case of an underwritten public offering, regardless of any
action whatsoever that a Holder may have taken, whether as a result of the
issuance by the Company of any notice hereunder or otherwise.

     3.   Holdback Agreement.  If (i) the Company shall file a registration
          ------------------                                  
statement with respect to the Common Stock or similar securities or securities
convertible into, or exchangeable or exercisable for, such securities and (ii)
the Company (in the case of a nonunderwritten public offering by the Company
pursuant to such registration statement) advises the Holders in writing that a
public sale or distribution of Registrable Shares would materially adversely
affect such offering or the managing underwriter or underwriters (in the case of
an underwritten public offering by the Company pursuant to such registration
statement) advises the Company in writing (in which case the Company shall
notify the Holders) that a public sale or distribution of Registrable Shares
would have material adverse impact on such offering, then each Holder shall, to
the extent not inconsistent with applicable law, refrain from effecting any
public sale or distribution of Registrable Shares during the 10 days prior to
the effective date of such registration statement and until the earliest of (A)
the abandonment of such offering, (B) 90 days from the effective date of such
registration statement and (C) if such offering is an underwritten offering, the
termination of any "hold back" period obtained by the underwriter or
underwriters 

                                       4
<PAGE>
 
in such offering from the Company in connection therewith (each such period, a
"Hold Back Period"); provided that the Hold Back Period shall not be more than
- ----------------    -------------                               
180 days in the case of an "Initial Public Offering" of the Company's Common
Stock and not more than 90 days in the case of any other public offering.

registration pursuant to Section 3(c) hereof, use commercially reasonable

the Registrable Shares covered by such Registration Statement, make generally
available earnings statements satisfying the provisions of Section 11(a) of the
Securities Act (provided that the Company shall be deemed to have complied with
this clause if it has complied with Rule 158 under the Securities Act), and
cause the related Prospectus as so supplemented to be filed pursuant to Rule 424
under the Securities Act; provided, however, that before filing a Registration
Statement or Prospectus, or any amendments or supplements thereto (other than
reports required to be filed by it under the Exchange Act), the Company shall
furnish to the Holders of Registrable Shares covered by such Registration
Statement and their counsel for review and comment, copies of all documents
required to be filed at least 3 business days prior to filing such documents
with the SEC;

          (d) notify the Holders of any Registrable Shares covered by such
Registration Statement promptly and (if requested) confirm such notice in
writing, (i) when a Prospectus or any Prospectus supplement or post-effective
amendment has been filed, and, with respect to such Registration Statement or
any post-effective amendment, when the same has 

                                       5
<PAGE>
 
become effective, (ii) of any request by the SEC for amendments or supplements
to such Registration Statement or the related Prospectus or for additional
information regarding such Holders, (iii) of the issuance by the SEC of any stop
order suspending the effectiveness of such Registration Statement or the
initiation of any proceedings for that purpose, (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Shares for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, and (v) of the happening of any event that requires the making of any
changes in such Registration Statement, Prospectus or documents incorporated or
deemed to be incorporated therein by reference so that they will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading;

          (e) use commercially reasonable efforts to obtain the withdrawal of
any order suspending the effectiveness of such Registration Statement, or the
lifting of any suspension of the qualification or exemption from qualification
of any Registrable Shares for sale in any jurisdiction in the United States;

Registration Statement, each counsel for such Holders and each managing
underwriter, if any, without charge, one conformed copy each of such
Registration Statement, as declared effective by the SEC, and of each post-
effective amendment thereto, in each case including financial statements and
schedules and all exhibits and reports incorporated or deemed to be incorporated
therein by reference; and deliver, without charge, such number of copies of the
preliminary prospectus, any amended preliminary prospectus, each final

Registrable Shares of such Holder covered by such Registration Statement in
conformity with the requirements of the Securities Act;

          (g) prior to any public offering of Registrable Shares covered by such
Registration Statement, use commercially reasonable efforts to register or
qualify such Registrable Shares for offer and sale under the securities or Blue

reasonably request in writing; provided, however, that the Company shall in no
event be required to qualify generally to do business as a foreign corporation
or as a dealer in any jurisdiction where it is not at the time so qualified or
to execute or file a general consent to service of process in any such
jurisdiction where it has not theretofore done so or to take any action that
would subject it to general service of process or taxation in any such
jurisdiction where it is not then subject;

          (h) upon the occurrence of any event contemplated by paragraph 4(d)(v)
above or as reasonably requested by the Holders, prepare a supplement or post-
effective amendment to such Registration Statement or the related Prospectus or
any document incorporated or deemed to be incorporated therein by reference and

<PAGE>
 
contain an untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading;

          (i) use commercially reasonable efforts to cause all Registrable

or other agent retained by any such Holder or underwriter (collectively, the
"Inspectors"), such financial and other records and other information, pertinent
- -----------

to enable them to exercise their due diligence responsibilities; provided,
however, that the Records that the Company determines, in good faith, to be
confidential and which it notifies the Inspectors in writing are confidential
shall not be disclosed to any Inspector unless such Inspector signs a
confidentiality agreement reasonably satisfactory to the Company, which
agreement shall permit the disclosure of such Records in such Registration
Statement or the related Prospectus if either (i) the disclosure of such Records
is necessary to avoid or correct a misstatement or omission in such Registration
Statement or (ii) the release of such Records is ordered pursuant to a subpoena
or other order from a court of competent jurisdiction; provided however, that
(A) any decision regarding the disclosure of information pursuant to subclause
(i) shall be made only after consultation with counsel for the applicable
Inspectors and the Company and (B) with respect to any release of Records
pursuant to subclause (ii), each Holder of Registrable Shares agrees that it
shall, promptly after learning that disclosure of such Records is sought in a
court having jurisdiction, give notice to the Company so that the Company, at
the Company's expense, may undertake appropriate action to prevent disclosure of
such Records; and

          (m) if such offering is an underwritten offering, enter into such
agreements (including an underwriting agreement in form, scope and substance as
is customary in underwritten offerings) and take all such other appropriate and
reasonable actions requested by the Holders of a majority of the Registrable
Shares being sold in connection therewith (including those reasonably requested
by the managing underwriters) in order to expedite or facilitate the disposition
of such Registrable Shares, and in such connection, (i) use commercially
reasonable 

                                       7
<PAGE>
 
efforts to obtain opinions of counsel to the Company and updates thereof (which
counsel and opinions (in form, scope and substance) shall be reasonably
satisfactory to the managing underwriters and counsel to the Holders of the
Registrable Shares being sold), addressed to each selling Holder of Registrable
Shares covered by such Registration Statement and each of the underwriters as to
the matters customarily covered in opinions requested in underwritten offerings
and such other matters may be reasonably requested by such counsel and
underwriters, (ii) use commercially reasonable efforts to obtain "cold comfort"
letters and updates thereof from the independent certified public accountants of
the Company (and, if necessary, any other independent certified public
accountants of any subsidiary of the Company or of any business acquired by the
Company for which financial statements and financial data are, or are required
to be, included in the Registration Statement), addressed to each selling holder
of Registrable Shares covered by the Registration Statement (unless such
accountants shall be prohibited from so addressing such letters by applicable
standards of the accounting profession) and each of the underwriters, such
letters to be in customary form and covering matters of the type customarily
covered in "cold comfort" letters in connection with underwritten offerings
(iii) if requested and if an underwriting agreement is entered into, provide
indemnification provisions and procedures substantially to the effect set forth
in Section 7 hereof with respect to all parties to be Indemnified pursuant to
said Section. The above shall be done at each closing under such underwriting or
similar agreement, or as and to the extent required thereunder. In addition, the
Company agrees (i) not to effect any public sale or distribution of its Common
Stock or any securities convertible into or exchangeable or exercisable for such
securities, during the 10 days prior to the effective date of any underwritten
Piggyback Registration and until the earliest of (A) the abandonment of such
offering, or (B) the termination of any "hold back" period reasonably requested
by the underwriters (with exceptions for issuances pursuant to outstanding
options, warrants, and convertible or exchangeable securities, pursuant to
employee and dividend reinvestment plans, and such other exceptions as are
customary or agreed with the managing underwriter).

          The Company may require each Holder of Registrable Shares covered by a
Registration Statement to furnish such information regarding such Holder and
such Holder's intended method of disposition of such Registrable Shares as it
may from time to time reasonably request in writing.  If any such information is
not furnished within a reasonable period of time after receipt of such request,
the Company may exclude such Holder's Registrable Shares from such Registration
Statement.

          Each Holder of Registrable Shares covered by a Registration Statement
agrees that, upon receipt of any notice from the Company of the happening of any
event of the kind described in Section 4(d)(ii), 4(d)(iii), 4(d)(iv) or 4(d)(v)
hereof, such Holder shall forthwith discontinue disposition of any Registrable
Shares covered by such Registration Statement or the related Prospectus in any
jurisiction in which such an event has occurred until receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 4(h) hereof, or
until such Holder is advised in writing (the "Advice") by the Company that the
                                              ------                          
use of the applicable Prospectus may be resumed, and has received copies of any
amended or supplemented Prospectus or any additional or supplemental filings
which are incorporated, or deemed to be incorporated, by reference in such
Prospectus (such period during which disposition is discontinued being an

                                       8
<PAGE>
 
"Interruption Period") and, if requested by the Company, the Holder shall
- --------------------                                                     
deliver to the Company (at the expense of the Company) all copies then in its
possession, other than permanent file copies then in such holder's possession,
of the Prospectus covering such Registrable Shares at the time of receipt of
such request.

          Each Holder of Registrable Shares covered by a Registration Statement
further agrees not to utilize any material other than the applicable current
preliminary prospectus or Prospectus in connection with the offering such
Registrable Shares.

     5.   Registration Expenses.  Whether or not any Registration Statement is
          ---------------------                                  
filed or becomes effective, the Company shall pay all costs, fees and expenses

including (i) all registration and filing fees, including NASD filing fees, (ii)
all fees and expenses of compliance with securities or Blue Sky laws, including
reasonable fees and disbursements of counsel in connection therewith, (iii)

counsel for the Company, (vi) fees and disbursements of all independent
certified public accountants of the Company (including expense of any "cold
comfort" letters required in connection with this Agreement) and all other
persons retained by the Company in connection with this Agreement) and all other
persons retained by the Company in connection with such Registration Statement,
and (vii) all other costs, fees and expenses incident to the Company's
performance or compliance with this Agreement. Notwithstanding the foregoing,
any discounts, commissions or brokers' fees or fees of similar securities
industry professionals and any transfer taxes relating to the disposition of the
Registrable Shares by a Holder, will be payable by such Holder and the Company
will have no obligation to pay any such amounts.

     6.   Underwriting Requirements.
          ------------------------- 

          (a) The Company shall have the right to determine whether any public
offering of securities and any accompanying Piggyback Registration shall be an
underwritten offering.

          (b) In the case of any underwritten offering pursuant to a Piggyback
Registration, the Company shall select the institution or institutions that
shall manage or lead such offering.

     7.   Indemnification.
          --------------- 

          (a) Indemnification by the Company.  The Company shall, without
              ------------------------------                             
limitation as to time, indemnify and hold harmless, to the full extent permitted
by law, each Holder of Registrable Shares whose Registrable Shares are covered
by a Registration Statement or Prospectus, the officers, directors and agents
and employees of each of them, each Person who 

                                       9
<PAGE>
 
controls each such Holder (within the meaning of Section 15 of the Securities
Act or Section 20 of the Exchange Act) and the officers, directors, agents and
employees of each such controlling person, to the fullest extent lawful, from
and against any and all losses, claims, damages, liabilities, judgment, costs
(including, without limitation, costs of preparation and reasonable attorneys'
fees) and expenses (collectively, "Losses"), as incurred, arising out of or
                                   ------
based upon any untrue or alleged untrue statement of a material fact contained
in such Registration Statement or Prospectus or in any amendment or supplement
thereto or in any preliminary prospectus, or arising out of or based upon any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as the
same are based upon information furnished in writing to the Company by or on
behalf of such Holder expressly for use therein; provided, however, that the
Company shall not be liable to any such Holder to the extent that any such
Losses arise out of or are based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in any preliminary prospectus if
(i) having previously been furnished by or on behalf of the Company with copies
of the Prospectus, such Holder failed to send or deliver a copy of the
Prospectus with or prior to the delivery of written confirmation of the sale of
Registrable Shares by such Holder to the person asserting the claim from which
such Losses arise and (ii) the Prospectus would have corrected in all material
respects such untrue statement or alleged untrue statement or such omission or
alleged omission; and provided further, however, that the Company shall not be
liable in any such case to the extent that any such Losses arise out of or are
based upon an untrue statement or alleged untrue statement or omission or
alleged omission in the Prospectus, if (x) such untrue statement or alleged
untrue statement, omission or alleged omission is corrected in all material
respects in an amendment or supplement to the Prospectus and (y) having
previously been furnished by or on behalf of the Company with copies of the
Prospectus as so amended or supplemented, such Holder thereafter fails to
deliver such Prospectus as so amended or supplemented, prior to or currently
with the sale of Registrable Shares. In connection with any Underwritten
Offering, the Company will also indemnify underwriters, selling brokers, dealer
managers and similar securities industry professionals participating in the
distribution, their officers and directors and each Person who controls such
Persons (within the meaning of Section 15 of the Securities Act) to the same
extent as provided above with respect to Indemnification of Holders of
Registrable Shares, or on such other terms as are reasonable and customary and
requested by the managing underwriter.

          (b) Indemnification by Holder of Registrable Shares.  In connection
              -----------------------------------------------                
with any Registration Statement in which a Holder is participating, such Holder
shall furnish to the Company in writing such information as the Company
reasonably requests for use in connection with such Registration Statement or
the related Prospectus and agrees to indemnify, to the full extent permitted by
law, the Company, its directors, officers, agents or employees, each Person who
controls the Company (within the meaning of Section 15 of the Securities Act and
Section 20 of the Exchange Act) and the directors, officers, agents or employees
of such controlling Persons, from and against all Losses arising out of or based
upon any untrue or alleged untrue statement of a material fact contained in such
Registration Statement or the related Prospectus or any amendment or supplement
thereto, or any preliminary prospectus, or arising out of or based upon any
omission or alleged omission of a material fact required to be stated 

                                       10
<PAGE>
 
therein or necessary to make the statements therein not misleading, to the
extent, but only to the extent, that such untrue or alleged untrue statement or
omission or alleged omission is based upon any information so furnished in
writing by or on behalf of such Holder to the Company expressly for use in such
Registration Statement or Prospectus.

          (c) If any Person shall be entitled to indemnity hereunder (an
"Indemnified Party"), the Indemnified Party shall give prompt notice to the
- ------------------                                                         
party from which such indemnity is sought (the "Indemnifying Party") of any
                                                ------------------         
claim or of the commencement of any proceeding with respect to which the
Indemnified Party seeks indemnification or contribution pursuant hereto;
provided, however, that the delay or failure to so notify the Indemnifying Party
shall not relieve the Indemnifying Party from any obligation or liability except
to the extent that the Indemnifying Party has been materially prejudiced by such
delay or failure.  The Indemnifying Party shall have the right, exercisable by
giving written notice to an Indemnified Party promptly after the receipt of
written notice from such Indemnified Party of such claim or proceeding, to
assume, at the Indemnifying Party's expense, the defense of any such claim or
proceeding, with counsel reasonably satisfactory to such Indemnified Party;
provided, however, that (i) an Indemnified Party shall have the right to employ
separate counsel in any such claim or proceeding and to participate in the
defense thereof, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party unless: (1) the Indemnifying Party agrees to
pay such fees and expenses; (2) the Indemnifying Party fails promptly to assume
the defense of such claim or proceeding or fails to employ counsel reasonably
satisfactory to such Indemnified Party; or (3) the named parties to any
proceeding (including impleaded parties) include both such Indemnified Party and
the Indemnifying Party, and such Indemnified Party shall have been advised by
counsel that there may be one or more legal defenses available to it that are
inconsistent with those available to the Indemnifying Party or that a conflict
of interest is likely to exist among such Indemnified Party and any other
Indemnified Parties (in which case the Indemnifying Party shall not have the
right to assume the defense of such action on behalf of such Indemnified Party);
and (ii) subject to clause (3) above, the Indemnifying Party shall not, in
connection with any one such claim or proceeding or separate but substantially
similar or related claims or proceedings in the same jurisdiction, arising out
of the same general allegations or circumstances, be liable for the fees and
expenses of more than one firm of attorneys (together with appropriate local
counsel) at any time for all of the Indemnified Parties, or for fees and
expenses that are not reasonable.  Whether or not such defense is assumed by the
Indemnifying Party, such Indemnified Party shall not be subject to any liability
for any settlement made without its consent.  The Indemnifying Party shall not
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release, in form and substance reasonably
satisfactory to the Indemnified Party, from all liability in respect of such
claim or litigation for which such Indemnified Party would be entitled to
indemnification hereunder.

          (d) Contribution.  If the indemnification provided for in this Section
              ------------                                                      
7 is unavailable to an Indemnified Party in respect of any Losses (other than in
accordance with its terms), then each applicable Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnifying Party as a result of such 

                                       11
<PAGE>
 
Losses, in such proportion as is appropriate to reflect the relative fault of
the Indemnifying Party, on the one hand, and such Indemnifying Party, on the
other hand, in connection with the actions, statements or omissions that
resulted in such Losses as well as any other relevant equitable considerations.
The relative fault of such Indemnifying Party, on the one hand, and Indemnified
Party, on the other hand, shall be determined by reference to, among other
things, whether any action in question, including any untrue statement of a
material fact or omission or alleged omission to state a material fact, has been
taken by, or relates to information supplied by, such Indemnifying Party or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent any such action, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include any legal or other fees or expenses incurred by such party
in connection with any investigation or proceeding. The parties hereto agree
that it would not be just and equitable if contribution pursuant to this Section
7(d) were determined by pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in the
immediately preceding paragraph. Notwithstanding the provision of this Section
7(d), an Indemnifying Party that is a Holder shall not be required to contribute
any amount which is in excess of the amount by which the total proceeds received
by such Holder from the sale of the Registrable Shares sold by such Holder (net
of all underwriting discounts and commissions) exceeds the amount of any damages
that such Indemnifying Party has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          8.  Rule 144.  If the Company shall have filed a registration
              --------                                                 
statement pursuant to the requirements of Section 12 of the Securities Exchange
Act or a registration statement pursuant to the requirements of the Securities
Act, the Company covenants that it will timely file the reports required to be
filed by it under the Securities Act or the Exchange Act (including but not
limited to the reports under Sections 13 and 15(d) of the Exchange Act referred
to in subparagraph (c)(1) of Rule 144 adopted by the SEC under the Securities
Act) and the rules and regulations adopted by the SEC thereunder (or if the
Company is not required to file such reports, the Company will, upon the request
of any Holder of Registrable Shares, make publicly available other information),
and will take such further action as any Holder of Registrable Shares may
reasonably request, all to the extent required from time to time to enable such
Holder of Registrable Shares to sell Registrable Shares within the exemption
provided by (i) Rule 144 under the Securities Act, as such Rule may be amended
from time to time, or (ii) any similar rule or regulation hereafter adopted by
the SEC.  Upon the request of any Holder of Registrable Shares, the Company will
deliver to such Holder, a written statement as to whether it has complied with
such requirements.

          9.  Miscellaneous.
              ------------- 

              (a) Termination.  This Agreement and the obligations of the
                  -----------
Company and the Holders hereunder (other than Section 7 hereof) shall terminate
on the first date on which no Registrable Shares remain outstanding.

          (b) Notices.  All notices, requests, demands and other communications
              -------                                                          
which are required or may be given under this Agreement shall be in writing and
shall be deemed to have been duly given when received if personally delivered;
when transmitted if transmitted by telecopy, electronic or digital transmission
method and such transmission is confirmed; the day after it is sent, if sent for
next day delivery to a domestic address by recognized overnight delivery service
(e.g., Federal Express); and upon receipt, if sent by certified or registered
mail, return receipt requested.  In each case notice shall be sent to the
address nest to partys name on the signature page hereto.

          (c) Interpretation.  When a reference is made in this Agreement to
              --------------                                                
Sections, such reference shall be to a Section of this Agreement unless
otherwise indicated.  Headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.  Whenever the word "include", "includes" or "including" are used
in this Agreement, they shall be deemed to be followed by the words "without
limitation".  This Agreement shall not be construed for or against either party
by reason of the authorship or alleged authorship of any provision hereof or by
reason of the status of the respective parties.  All terms defined in this
Agreement in the singular shall have the same comparable meanings when used in
the plural and vice versa, unless otherwise specified.

          (d) Entire Agreement; No Third-Party Beneficiaries.  This Agreement
              ----------------------------------------------                 
constitutes the entire agreement and supersedes all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof and is not intended to confer upon any person other than
the parties hereto any rights or remedies hereunder.

          (e) Governing Law.  This Agreement shall be construed, interpreted and
              -------------                                                     
the rights of the parties determined in accordance with the laws of the State of
California (without reference to the choice of law provisions

          (f) Severability.  Each party agrees that, should any court or other
              ------------                                                    
competent authority hold any provision of this Agreement or part hereof to be
null, void or unenforceable, or order any party to take any action inconsistent
herewith or not to take an action consistent herewith or required hereby, the
validity, legality and enforceability of the remaining provisions and
obligations contained or set forth herein shall not in any way be affected or
impaired thereby.  Upon any such holding that any provision of this Agreement is
null, void or unenforceable, the parties will negotiate in good faith to modify
this Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner to the end that the transactions contemplated
by this Agreement are consummated to the extent possible.  Except as otherwise
contemplated by this Agreement, to the extent that a party hereto took an action
inconsistent herewith or failed to take action consistent herewith or required
hereby pursuant to an order or judgment of a court or other competent authority,
such party shall incur no liability or obligation unless such party did not in
good faith seek to resist or object to the imposition or entering of such order
or judgment.

          (g) Injunctive Relief.  The parties acknowledge that it will be
              -----------------                                          
impossible to measure in money the damages that would be suffered if the parties
fail to comply with any of the obligations herein imposed on them and that in
the event of any such failure, an aggrieved person or entity will be irreparably
damaged and will not have an adequate remedy at law.  Any such person or entity
shall, therefore, be entitled to injunctive relief, including specific
performance, to enforce such obligations, and if any action should be brought in
equity to enforce any of the provisions of this Agreement, none of the parties
shall raise the defense that there is an adequate remedy at law.

          (h) Attorneys' Fees.  If any party to this Agreement brings an action
              ---------------                                                  
to enforce its rights under this Agreement, the prevailing party shall be
entitled to recover its costs and expenses, including without limitation
reasonable attorneys' fees, incurred in connection with such action, including
any appeal of such action.

          (i) Cumulative Remedies.  All rights and remedies of either party
              -------------------                                          
hereto are cumulative of each other and of every other right or remedy such
party may otherwise have at law or in equity, and the exercise of one or more
rights or remedies shall not prejudice or impair the concurrent or subsequent
exercise of other rights or remedies.

          (j) Counterparts.  This Agreement may be executed in two or more
              ------------                                                
counterparts, all of which shall be considered one and the same instrument and
shall become effective when executed and delivered by each of the parties.

          (k) Amendments and Waivers.  Except as otherwise provided herein, the
              ----------------------                                           
provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
unless the Company has obtained the written consent of Holders of at least a
majority in number of the Registrable Shares then outstanding.

          (l) Publicity.  No public release or announcement concerning the
              ---------                                                   
transactions contemplated hereby shall be issued by any party without the prior
consent of the other parties, except to the extent that such party is advised by
counsel that such release or announcement is necessary or advisable under
applicable law or the rules or regulations of any securities exchange, in which
case the party required to make the release or announcement shall to the extent
practicable provide the other party with an opportunity to review and comment on
such release or announcement in advance of its issuance.

          2.5.  Improper Transfer.
                -----------------

                            Rights of First Offer
                            ---------------------

          3.1.  Transfers by a Stockholder.
                -------------------------- 

          (a)  Except for the sale of securities contemplated by Article IV and
transfers permitted by Section 2.2, if any Stockholder shall desire to transfer
any shares of the Company Common Stock owned by it (such Stockholder desiring to
transfer shares of the Company Common Stock being referred to herein as a
"Selling Stockholder"), then such Selling Stockholder shall deliver written
notice of its desire to transfer shares other than to a Permitted Transferee (a
"Notice of Intention"), accompanied by a copy of a proposal relating to such
transfer (the "Sale Proposal"), to the Company and to each of the other
Stockholders setting forth such Selling Stockholder's desire to make such
transfer (which shall be for cash only), the number of shares of the Company
Common Stock proposed to be transferred (the "Offered Shares"), and the cash
price at which such Selling Stockholder proposes to transfer the Offered Shares
(the "Offer Price").

          (b)  Upon receipt of the Notice of Intention, the Company shall have
the right to purchase at the Offer Price all but not less than all of the
Offered Shares, exercisable by the delivery of notice to the Selling Stockholder
(the "Notice of Exercise"), within 30 calendar days from the date of receipt of
the Notice of Intention. The right to purchase pursuant to this Section 3.1(b)
shall terminate if not exercised within 30 calendar days after receipt of the
Notice of Intention.

          In the event that, if applicable, the option of the Company referred
to in the previous paragraph terminates and there are remaining Offered Shares
for which Notices of Exercise have not been received, the Selling Stockholder
shall give notice thereof to the other Stockholders, setting forth the number of
Offered Shares remaining to be sold pursuant to this Section 3.1(b). Such
Stockholders shall then have the right to purchase all but not less than all the
remaining Offered Shares pro rata based on the number of shares of the Company
Common Stock owned by each, by delivery of a Notice of Exercise. The right of
the Stockholders pursuant to Section 3.1(b) shall terminate if not exercised
within 30 calendar days after receipt from the Selling Stockholder of such
notice.

          (c)  In the event that the Company and/or the Stockholders exercise
their rights to purchase all, but not less than all, of the Offered Shares in
accordance with Section 3.1(b), then the Selling Stockholder must sell the
Offered Shares to the Company and/or to such Stockholders after not less than 30
days and not more than 60 calendar days from the date of the delivery of last
Notice of Exercise received by the Selling Stockholder. The Selling Stockholder
shall notify the Company and each such Stockholder of the number of Offered
Shares to be sold to the Company and such Stockholders. Upon the consummation of
such purchase and sale, the Selling Stockholder shall deliver certificates
evidencing the Offered Shares sold duly endorsed, or accompanied by written
instruments of transfer in form satisfactory to the purchaser duly executed, by
the Selling Stockholder, free and clear of any liens (other than those under
this 

                                       4
<PAGE>
 
Agreement), against delivery of the Offer Price payable in accordance with the
notice specified in Section 3.1(a).


          3.2.  Transfer of Offered Shares to Third Parties.
                ------------------------------------------- 

          If all notices required to be given pursuant to Section 3.1 have been
duly given and the Company and/or the Stockholders determine not to exercise
their respective options to purchase the Offered Shares at the Offer Price or
determine to exercise their respective options to purchase less than all of the
Offered Shares then the Selling Stockholder shall have the right, for a period
of 120 calendar days from the earlier of (i) the expiration of the last
applicable option period pursuant to Section 3.1 with respect to such Sale
Proposal or (ii) the date on which such Selling Stockholder receives notice from
all other Stockholders that they will not exercise in whole or in part the
options granted pursuant to Section 3.1, to sell to any Third Party the Offered
Shares remaining unsold at a price not less favorable than the Offer Price and
on terms and conditions as favorable as offered to the Company and the
Stockholders.


          3.3.  Waiting Period with Respect to Subsequent Transfers.
                --------------------------------------------------- 

          In the event that the Company and/or the Stockholders do not exercise
their options to purchase any or all of the Offered Shares, and the Selling
Stockholder shall not have sold the remaining Offered Shares to a Third Party
for any reason before the expiration, as applicable, of the 120-day period
described in Section 3.2, then such Selling Stockholder shall not give another
Notice of Intention pursuant to Section 3.1 for a period of 90 calendar days
from the last day of such 120-day period.


          3.4.  Lapse of Certain Rights of First Offer.
                -------------------------------------- 

          After a Public Distribution, transfers of shares of the Company Common
Stock by a Stockholder shall not be subject to the requirements of this Article
III; provided that such transfers are made in accordance with the exemption
provided by Rule 144 under the Securities Act.


                                 ARTICLE IV.


                  Drag-Along Requirements; Public Offering
                  ----------------------------------------


          4.1.  Drag-Along Right.
                ---------------- 

          If a Third Party makes a bona fide offer for substantially all of the
Company Common Stock, which offer a majority of the Company's Stockholders vote
to accept, then the Stockholders voting in favor of such offer shall have the
right (the "Drag-Along Right") to compel the other Stockholders to sell and all
Stockholders hereby agree to sell all, but not less than all, shares of the
Company Common Stock owned, directly or indirectly, by them to such Third Party;
provided, however, that all Stockholders shall receive identical consideration
- --------  -------                                                             
per share pursuant to such transfer. This Drag-Along Right may be exercised by
the majority Stockholders by providing the other Stockholders with notice (the
"Drag-Along Notice") setting 

                                       5
<PAGE>
 
forth (i) the time and place of the closing of the Drag-Along Right, which
time and place shall not be less than 5 business days after the date of the
Drag-Along Notice and (ii) the expected consideration to be paid at such
closing.


          4.2.  Payment of Drag-Along Purchase Price.
                ------------------------------------ 

          At the closing of the Drag-Along Right, the third party shall remit to
all Stockholders identical consideration (the cash portion of which, if any,
will be in the form of a certified check or similarly available funds) for each
share of the Company Common Stock sold pursuant to the Drag-Along Right, against
delivery by each Stockholder subject to the Drag-Along Right of certificates for
all shares of the Company Common Stock owned by each such Stockholder, duly
endorsed or with duly executed stock powers, warranting as to good and
marketable title, free and clear of any liens, encumbrances and adverse claims,
and the compliance with any other conditions of closing applicable to the other
Stockholders.


                                 ARTICLE V.

violation of this Agreement).


                                 ARTICLE VI.


                                Miscellaneous

          (a)  Except for the sale of securities contemplated by Article IV and

Offered Shares to the Company and/or to such Stockholders after not less than 30
days and not more than 60 calendar days from the date of the delivery of last

          SECTION 5. Optionee Put.  The Company agrees that, in the event that
                     ------------

Final Expiration Date, reserve and keep available, free from preemptive rights,
out of the aggregate of its authorized but unissued Common Stock or its
authorized and issued Common Stock held in its treasury, for the purpose of
enabling it to satisfy any obligation to issue Option Shares upon exercise of
this Option, the maximum number of shares of Common Stock which may then be
deliverable upon the exercise of this Option.

          SECTION 7. Adjustment of Exercise Price and Number of Option Shares
                     --------------------------------------------------------

- --------                                                                       
exercise of each Option are subject to adjustment from time to time upon the
occurrence of the events enumerated in this Section 7.


               (a)  Adjustment for Change in Common Stock.
                    ------------------------------------- 

                    If the Company:

                    (i)   pays a dividend or makes a distribution on its Common
     Stock in shares of its Common Stock;

                    (ii)  subdivides its outstanding shares of Common Stock into
     a greater number of shares;

                    (iii) combines its outstanding shares of Common Stock into a
     smaller number of shares;

then the number of Option Shares and the Exercise Price in effect immediately
prior to such action shall be proportionately adjusted so that, if Employee
thereafter exercises this Option, it may receive the aggregate number and kind
of shares of capital stock of the Company which it would have owned immediately
following such action if this Option had been exercised immediately prior to
such action.

          The adjustment shall become effective immediately after the record
date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision or combination.

               (b)  Notice of Adjustment.
                    -------------------- 

          The Company shall provide Employee with written notice of any of the
foregoing adjustments at least 15 days before the effective date of the
adjustment.

               (c)  Reorganization of Company.
                    ------------------------- 

          If the Company consolidates or merges with or into, or transfers or
leases all or substantially all its assets to, any person, upon consummation of
such transaction the Option 

                                       5
<PAGE>
 
shall automatically become exercisable for the kind and amount of securities,
cash or other assets which the holder of a Option would have owned immediately
after the consolidation, merger, transfer or lease if the holder had exercised
the Option immediately before the effective data of the transaction.
Concurrently with the consummation of such transaction, the Corporation formed
by or surviving any such consolidation or merger if other than the Company, or
the person to which such sale or conveyance shall have been made, shall enter
into a supplemental Option Agreement so providing and further providing for
adjustments which shall be as nearly equivalent as may be practical to the
adjustments provided for in this Section. The successor Company shall mail to
Employee a notice describing the supplemental Option Agreement.

          If the issuer of securities deliverable upon exercise of Options under
the supplemental Option Agreement is an affiliate of the formed, surviving,
transferee or lessee corporation, that issuer shall join in the supplemental
Option Agreement.

          If this subsection (c) applies, subsections (a) and (b) of this
Section 7 do not apply.

          SECTION 8. Notices to Company and Employee.  Unless otherwise provided

     benefit plan of the Company) of all or substantially all of the Company's
     assets or 51% or more of the Company's then outstanding voting stock, or
     the liquidation or dissolution of the Company, unless the Company waives

     such event if the Option has then neither been fully exercised nor become
     unexercisable under this Section 4 (b).

                      ------------

(i) all, but not less than all, of Optionee's rights under this Option
Agreement, in the event Optionee has not exercised the Option; or (ii) all, but
not less than all, of Optionee's Option Shares, in the event Optionee has
exercised the Option.  Optionee shall notify the Company of his intent to
exercise his rights under this Section 5 not more than 60 days after the
effective date of the termination of his employment with the Company. Optionee's
rights under this Section 5 shall be subject to and consummated in compliance

the Employee's willful misconduct or habitual neglect of his duties as an
employee, (y) dishonest or illegal conduct by the Employee or (z) the Employee's

the Company has attempted to accommodate); or (b) a substantial reduction by the
Company in the Employee's compensation from that provided on the date of this
Option Agreement (unless other employees of the Company are subject to a similar
reduction due to the financial condition of the Company).

                      ----------------------------                              
Final Expiration Date, reserve and keep available, free from preemptive rights,
out of the aggregate of its authorized but unissued Common Stock or its
authorized and issued Common Stock held in its treasury, for the purpose of
enabling it to satisfy any obligation to issue Option Shares upon exercise of
this Option, the maximum number of shares of Common Stock which may then be
deliverable upon the exercise of this Option.

          SECTION 7.  Adjustment of Exercise Price and Number of Option Shares
                      --------------------------------------------------------
Issuable.  The Exercise Price and the number of Option Shares issuable upon the
- --------                                                                       
exercise of each Option are subject to adjustment from time to time upon the
occurrence of the events enumerated in this Section 7.


               (a)  Adjustment for Change in Common Stock.
                    ------------------------------------- 

                    If the Company:

                    (i)    pays a dividend or makes a distribution on its
     Common Stock in shares of its Common Stock;

                    (ii)   subdivides its outstanding shares of Common Stock
     into a greater number of shares;

                    (iii)  combines its outstanding shares of Common Stock
     into a smaller number of shares;

then the number of Option Shares and the Exercise Price in effect immediately
prior to such action shall be proportionately adjusted so that, if Employee
thereafter exercises this Option, it may receive the aggregate number and kind
of shares of capital stock of the Company which it would have owned immediately
following such action if this Option had been exercised immediately prior to
such action.

          The adjustment shall become effective immediately after the record
date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision or combination.


               (b)  Notice of Adjustment.
                    -------------------- 

          The Company shall provide Employee with written notice of any of the
foregoing adjustments at least 15 days before the effective date of the
adjustment.


               (c)  Reorganization of Company.
                    ------------------------- 

          If the Company consolidates or merges with or into, or transfers or
leases all or substantially all its assets to, any person, upon consummation of
such transaction the Option 

                                       5
<PAGE>
 
shall automatically become exercisable for the kind and amount of securities,
cash or other assets which the holder of a Option would have owned immediately
after the consolidation, merger, transfer or lease if the holder had exercised
the Option immediately before the effective date of the transaction.
Concurrently with the consummation of such transaction, the Corporation formed
by or surviving any such consolidation or merger if other than the Company, or
the person to which such sale or conveyance shall have been made, shall enter
into a supplemental Option Agreement so providing and further providing for
adjustments which shall be as nearly equivalent as may be practical to the
adjustments provided for in this Section. The successor Company shall mail to
Employee a notice describing the supplemental Option Agreement.

          If the issuer of securities deliverable upon exercise of Options under
the supplemental Option Agreement is an affiliate of the formed, surviving,
transferee or lessee corporation, that issuer shall join in the supplemental
Option Agreement.

          If this subsection (c) applies, subsections (a) and (b) of this
Section 7 do not apply.

          SECTION 8.  Notices to Company and Employee.  Unless otherwise
                      -------------------------------                   
provided herein, all notices, requests, demands and other communications

          SECTION 4.  Exercise and Termination of Option.
                      ---------------------------------- 


          (a)  Exercise.  Employee may exercise this Option in whole or in part
               --------                                                        
at anytime prior to 5:00 p.m. Pacific time, December 31, 2003.  This Option
expires at 5:00 p.m. Pacific time, December 31, 2003 (the "Final Expiration
Date").

          Upon any partial exercise of this Option, this Option shall thereafter
represent the right to purchase only such Option Shares as remain unexercised.

          To exercise the Option, Employee shall deliver to the Company at the
address designated for such purpose in Section 8 hereof the form of Election to
Purchase attached hereto as Exhibit A along with payment of the Exercise Price
in current and immediately available funds for the number of Option Shares which
Employee wishes to purchase hereunder.  The Company will not be obligated to
issue fractions of shares of Common Stock.

          Upon such delivery of the Election to Purchase and payment of the
Exercise Price the Company shall issue and cause to be delivered with all
reasonable dispatch to Employee a certificate or certificates for the number of
Option Shares issuable upon the exercise of such Options.  The Option Shares,
when issued and delivered in accordance with this Agreement, will be duly and
validly authorized and issued, fully paid and nonassessable, and, assuming the
accuracy of Employee's representations set forth in Section 3, issued in
accordance with all applicable state and federal securities laws.  The Company
will pay any documentary stamp taxes attributable to the initial issuance of
Option Shares upon the exercise of Options.


          (b)  Termination.  This Option may not be exercised to any extent by
               -----------

     Optionee's termination of employment for any reason, unless the Optionee
     dies within said three-month period; or

               (iii) The expiration of one year from the date of the Optionee's
     death; or

               (iv)  The effective date of either the merger or consolidation of
     the Company with or into another corporation, or the acquisition by another
     corporation or person (excluding any employee benefit plan of the Company
     or any trustee or other fiduciary holding securities under an employee
     benefit plan of the Company) of all or substantially all of the Company's
     assets or 51% or more of the Company's then outstanding voting stock, or
     the liquidation or dissolution of the Company, unless the Company waives
     this provision in connection with such transaction.  At least ten days
     prior to the effective date of such merger, consolidation, acquisition,
     liquidation or dissolution, the Company shall give the Optionee notice of
     such event if the Option has then neither been fully exercised nor become
     unexercisable under this Section 4 (b).

          SECTION 5.  Optionee Put.  The Company agrees that, in the event that
                      ------------                                             
the Optionee's employment with the Company is terminated by the Company for any
reason other than Good Cause or he resigns his employment for "Good Reason," the
Optionee shall have the right to require the Company to purchase, for $50,000:
(i) all, but not less than all, of Optionee's rights under this Option
Agreement, in the event Optionee has not exercised the Option; or (ii) all, but
not less than all, of Optionee's Option Shares, in the event Optionee has
exercised the Option.  Optionee shall notify the Company of his intent to
exercise his rights under this Section 5 not more than 60 days after the
effective date of the termination of his employment with the Company. Optionee's
rights under this Section 5 shall be subject to and consummated in compliance
with the requirements of applicable laws and regulations, including without
limitation the requirements of the federal securities laws and state securities
or blue sky laws. The parties hereto agree to use all reasonable efforts to
take, or cause to be taken and to do, or cause to be done, all things necessary,
proper or advisable to consummate and make effective as promptly as practicable
the provisions of this Section 5.

          For the purposes of this Option Agreement, "Good Cause" shall mean (x)
the Employee's willful misconduct or habitual neglect of his duties as an
employee, (y) dishonest or illegal conduct by the Employee or (z) the Employee's
conviction of any felony or a misdemeanor involving moral turpitude.  "Good
Reason" shall mean the occurrence of any of the following events without the
Employee's express written consent:(a) the assignment to the Employee of duties
inconsistent with the position and status held by the Employee on the date of
this Option Agreement, or a substantial alteration in, the nature, status or
prestige of the Employee's responsibilities (other than any such alteration
primarily attributable to a medical or physical infirmity of the Executive which
the Company has attempted to accommodate); or (b) a substantial reduction by the
Company in the Employee's compensation from that provided on the date of this
Option Agreement (unless other employees of the Company are subject to a similar
reduction due to the financial condition of the Company).

Final Expiration Date, reserve and keep available, free from preemptive rights,
out of the aggregate of its authorized but unissued Common Stock or its
authorized and issued Common Stock held in its treasury, for the purpose of
enabling it to satisfy any obligation to issue Option Shares upon exercise of
this Option, the maximum number of shares of Common Stock which may then be
deliverable upon the exercise of this Option.

          SECTION 7.  Adjustment of Exercise Price and Number of Option Shares

- --------                                                                       
exercise of each Option are subject to adjustment from time to time upon the
occurrence of the events enumerated in this Section 7.


               (a)  Adjustment for Change in Common Stock.
                    ------------------------------------- 

                    If the Company:

                    (i)   pays a dividend or makes a distribution on its
     Common Stock in shares of its Common Stock;

                    (ii)  subdivides its outstanding shares of Common Stock
     into a greater number of shares;

                    (iii) combines its outstanding shares of Common Stock into
     a smaller number of shares;

then the number of Option Shares and the Exercise Price in effect immediately
prior to such action shall be proportionately adjusted so that, if Employee
thereafter exercises this Option, it may receive the aggregate number and kind
of shares of capital stock of the Company which it would have owned immediately
following such action if this Option had been exercised immediately prior to
such action.

          The adjustment shall become effective immediately after the record
date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision or combination.


               (b)  Notice of Adjustment.
                    -------------------- 

          The Company shall provide Employee with written notice of any of the
foregoing adjustments at least 15 days before the effective date of the
adjustment.


               (c)  Reorganization of Company.
                    ------------------------- 

          If the Company consolidates or merges with or into, or transfers or
leases all or substantially all its assets to, any person, upon consummation of
such transaction the Option 

                                       5
<PAGE>
 
shall automatically become exercisable for the kind and amount of securities,
cash or other assets which the holder of a Option would have owned immediately
after the consolidation, merger, transfer or lease if the holder had exercised
the Option immediately before the effective date of the transaction.
Concurrently with the consummation of such transaction, the Corporation formed
by or surviving any such consolidation or merger if other than the Company, or
the person to which such sale or conveyance shall have been made, shall enter
into a supplemental Option Agreement so providing and further providing for
adjustments which shall be as nearly equivalent as may be practical to the
adjustments provided for in this Section. The successor Company shall mail to
Employee a notice describing the supplemental Option Agreement.

          If the issuer of securities deliverable upon exercise of Options under
the supplemental Option Agreement is an affiliate of the formed, surviving,
transferee or lessee corporation, that issuer shall join in the supplemental
Option Agreement.

          If this subsection (c) applies, subsections (a) and (b) of this
Section 7 do not apply.

          SECTION 8.  Notices to Company and Employee.  Unless otherwise
                      -------------------------------                   
provided herein, all notices, requests, demands and other communications

or into another corporation, or the acquisition by another corporation or person
of all or substantially all of the Company's assets or eighty percent (80%) or
more of the Company's then outstanding voting stock, or the liquidation or
dissolution of the Company, the Company may, in its absolute discretion and upon
such terms and conditions as it deems appropriate, provide prior to such event,
that at some time prior to the effective date of such event this Option shall be
exercisable as to all the shares covered hereby, notwithstanding that this
Option may not yet have become fully exercisable under Section 3.1(a); provided,
however, that this acceleration of exercisability shall not take place if:

               (a)  This Option becomes unexercisable under Section 3.3 prior to
said effective date; or

               (b)  In connection with such an event, provision is made for an
assumption of this Option or a substitution therefor of a new option by an
employer corporation or a parent or subsidiary of such corporation; or

               (c)  The contemplated corporate transaction is not consummated;
and provided, further, that nothing in this Section 3.4 shall make this Option
exercisable if it is otherwise unexercisable by reason of Section 5.6.

                                  ARTICLE IV.
                               EXERCISE OF OPTION

Section 4.1.   Person Eligible to Exercise
               ---------------------------

               During the lifetime of the Optionee, only he may exercise the
Option or any portion thereof. After the death of the Optionee, any exercisable
portion of the Option may, prior to the time when the Option becomes
unexercisable under Section 3.3, be exercised by his personal representative or
by any person empowered to do so under the Optionee's will or under the then
applicable laws of descent and distribution.

Section 4.2.   Partial Exercise
               ----------------

               Any exercisable portion of the Option or the entire Option, if
then wholly exercisable, may be exercised in whole or in part at any time prior
to the time when the Option or portion thereof becomes unexercisable under
Section 3.3; provided, however, that each partial exercise shall be for not less
than ten (10) shares (or the minimum installment set forth in Section 3.1, if a
smaller number of shares) and shall be for whole shares only.

                                       5
<PAGE>
 
Section 4.3.   Manner of Exercise
               ------------------

               The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

               (a)  Notice in writing signed by the Optionee or the other person
then entitled to exercise the Option or portion, stating that the Option or
portion is thereby exercised, such notice complying with all applicable rules
established by the Company; and

               (b)  Full payment (in cash or by check) for the shares with
respect to which such Option or portion is exercised; and

               (c)  A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

               (d)  Full payment to the Company (or other employer corporation)
of all amounts which, under federal, state or local tax law, it is required to
withhold upon exercise of the option; and

               (e)  In the event the Option or portion shall be exercised
pursuant to Section 4.1 by any person or persons other than the Optionee,
appropriate proof of the right of such person or persons to exercise the Option.

Section 4.4.   Conditions to Issuance of Stock Certificates

               The shares of stock deliverable upon the exercise of the Option,
or any portion thereof, may be either previously authorized but unissued shares
or issued shares which have

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

               (a)  The obtaining of any approval or other clearance from any
state or federal governmental agency which the Company shall, in its absolute
discretion, determine to be necessary or advisable; and

               (b)  The payment to the Company (or other employer corporation)
of all amounts which, under federal, state or local tax law, it is required to
withhold upon exercise of the Option; and

               (c)  The lapse of such reasonable period of time following the
exercise of the Option as the Company may from time to time establish for
reasons of administrative convenience.

Section 4.5.   Rights as Shareholder
               ---------------------

purchasable upon the exercise of any part of the Option unless and until
certificates representing such shares shall have been issued by the Company to
such holder.

for any action, determination or interpretation made in good faith with respect
to the Option.

Section 5.2.   Option Not Transferable
               -----------------------

               Neither the Option nor any interest or right therein or part
thereof shall be liable for the debts, contracts or engagements of the Optionee
or his successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable

be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and

5.4, either party may hereafter designate a different address for notices to be
given to him. Any notice which is required to be given to the Optionee shall, if

representative if such representative has previously informed the Company of his
status and address by written notice under this Section 5.4. Any notice shall be
deemed duly given when enclosed in a properly sealed envelope or wrapper

branch post office regularly maintained by the United States Postal Service.

               (a)  There can be no valid transfer (as hereinafter defined) of
any shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

               (1)  Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

               (2)  For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

               (3)  The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

               (4)  If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b)  As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c)  None of the shares of the Company's stock purchased on exercise
of the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock evidencing shares 

                                       9
<PAGE>
 
of stock purchased on exercise of the Option shall bear an appropriate legend
referring to the transfer restrictions imposed by this Section 5.8 and to the
repurchase option provided for in Section 5.8.

that at some time prior to the effective date of such event this Option shall be
exercisable as to all the shares covered hereby, notwithstanding that this

however, that this acceleration of exercisability shall not take place if:

          (a) This Option becomes unexercisable under Section 3.3 prior to said

                              EXERCISE OF OPTION

Section 4.1.  Person Eligible to Exercise
              ---------------------------

          During the lifetime of the Optionee, only he may exercise the Option

empowered to do so under the Optionee's will or under the then applicable laws
of descent and distribution.

Section 4.2.  Partial Exercise
              ----------------

          Any exercisable portion of the Option or the entire Option, if then
wholly exercisable, may be exercised in whole or in part at any time prior to
the time when the Option or portion thereof becomes unexercisable under Section

ten (10) shares (or the minimum installment set forth in Section 3.1, if a

<PAGE>
 
Section 4.3.  Manner of Exercise
              ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

          (a) Notice in writing signed by the Optionee or the other person then
entitled to exercise the Option or portion, stating that the Option or portion
is thereby exercised, such notice complying with all applicable rules
established by the Company; and

          (b) Full payment (in cash or by check) for the shares with respect to
which such Option or portion is exercised; and

          (c) A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

          (d) Full payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (e) In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option.

Section 4.4.  Conditions to Issuance of Stock Certificates
              --------------------------------------------

          The shares of stock deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued shares or
issued shares which have 

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

          (a) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Company shall, in its absolute discretion,
determine to be necessary or advisable; and

          (b) The payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (c) The lapse of such reasonable period of time following the exercise
of the Option as the Company may from time to time establish for reasons of
administrative convenience.

Section 4.5.  Rights as Shareholder
              ---------------------

          The holder of the Option shall not be, nor have any of the rights or

representing such shares shall have been issued by the Company to such holder.

to the Option.

Section 5.2.  Option Not Transferable
              -----------------------

          Neither the Option nor any interest or right therein or part thereof
shall be liable for the debts, contracts or engagements of the Optionee or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and
distribution.

Section 5.8.  Restrictions on Transfer of Shares
              ----------------------------------

          (a) There can be no valid transfer (as hereinafter defined) of any
shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such 

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

              (1) Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

              (2) For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

              (3) The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

              (4) If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b) As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c) None of the shares of the Company's stock purchased on exercise of
the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock evidencing shares 

                                       9
<PAGE>
 
of stock purchased on exercise of the Option shall bear an appropriate legend

that at some time prior to the effective date of such event this Option shall be
exercisable as to all the shares covered hereby, notwithstanding that this
Option may not yet have become fully exercisable under Section 3.1(a); provided,
however, that this acceleration of exercisability shall not take place if:

              (a) This Option becomes unexercisable under Section 3.3 prior to
said effective date; or

              (b) In connection with such an event, provision is made for an
assumption of this Option or a substitution therefor of a new option by an
employer corporation or a parent or subsidiary of such corporation; or

              (c) The contemplated corporate transaction is not consummated; and
provided, further, that nothing in this Section 3.4 shall make this Option

                                  ARTICLE IV.
                              EXERCISE OF OPTION

Section 4.1.  Person Eligible to Exercise
              ---------------------------

              During the lifetime of the Optionee, only he may exercise the

portion of the Option may, prior to the time when the Option becomes

by any person empowered to do so under the Optionee's will or under the then
applicable laws of descent and distribution.

              Any exercisable portion of the Option or the entire Option, if

to the time when the Option or portion thereof becomes unexercisable under

<PAGE>
 
Section 4.3.  Manner of Exercise
              ------------------

              The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

              (a) Notice in writing signed by the Optionee or the other person
then entitled to exercise the Option or portion, stating that the Option or
portion is thereby exercised, such notice complying with all applicable rules
established by the Company; and

              (b) Full payment (in cash or by check) for the shares with respect
to which such Option or portion is exercised; and

              (c) A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

              (d) Full payment to the Company (or other employer corporation) of
all amounts which, under federal, state or local tax law, it is required to
withhold upon exercise of the Option; and

              (e) In the event the Option or portion shall be exercised pursuant
to Section 4.1 by any person or persons other than the Optionee, appropriate
proof of the right of such person or persons to exercise the Option.

Section 4.4.  Conditions to Issuance of Stock Certificates
              --------------------------------------------

              The shares of stock deliverable upon the exercise of the Option,
or any portion thereof, may be either previously authorized but unissued shares
or issued shares which have 

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

              (a) The obtaining of any approval or other clearance from any
state or federal governmental agency which the Company shall, in its absolute
discretion, determine to be necessary or advisable; and

              (b) The payment to the Company (or other employer corporation) of
all amounts which, under federal, state or local tax law, it is required to
withhold upon exercise of the Option; and

              (c) The lapse of such reasonable period of time following the
exercise of the Option as the Company may from time to time establish for
reasons of administrative convenience.

Section 4.5.  Rights as Shareholder
              ---------------------

              The holder of the Option shall not be, nor have any of the rights

purchasable upon the exercise of any part of the Option unless and until
certificates representing such shares shall have been issued by the Company to
such holder.

for any action, determination or interpretation made in good faith with respect
to the Option.

Section 5.2.  Option Not Transferable
              -----------------------

              Neither the Option nor any interest or right therein or part
thereof shall be liable for the debts, contracts or engagements of the Optionee
or his successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and
distribution.

representative if such representative has previously informed the Company of his
status and address by written notice under this Section 5.4. Any notice shall be

Section 5.8.  Restrictions on Transfer of Shares
              ----------------------------------

shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such 

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

               (1) Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

               (2) For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

               (3) The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

               (4) If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b)  As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c)  None of the shares of the Company's stock purchased on exercise
of the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock evidencing shares 

                                       9
<PAGE>
 
of stock purchased on exercise of the Option shall bear an appropriate legend
referring to the transfer restrictions imposed by this Section 5.8 and to the
repurchase option provided for in Section 5.8.

that at some time prior to the effective date of such event this Option shall be
exercisable as to all the shares covered hereby, notwithstanding that this

however, that this acceleration of exercisability shall not take place if:

          (a)  This Option becomes unexercisable under Section 3.3 prior to said

          (b)  In connection with such an event, provision is made for an

                                  ARTICLE IV.

                              EXERCISE OF OPTION

Section 4.1.  Person Eligible to Exercise
              ---------------------------

          During the lifetime of the Optionee, only he may exercise the Option

Section 3.3, be exercised by his personal representative or by any person
empowered to do so under the Optionee's will or under the then applicable laws
of descent and distribution.

Section 4.2.  Partial Exercise
              ----------------

          Any exercisable portion of the Option or the entire Option, if then

ten (10) shares (or the minimum installment set forth in Section 3.1, if a

<PAGE>
 
Section 4.3.  Manner of Exercise
              ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

          (a)  Notice in writing signed by the Optionee or the other person then
entitled to exercise the Option or portion, stating that the Option or portion
is thereby exercised, such notice complying with all applicable rules
established by the Company; and

          (b)  Full payment (in cash or by check) for the shares with respect to
which such Option or portion is exercised; and

          (c)  A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

          (d)  Full payment to the Company (or other employer corporation) of
all amounts which, under federal, state or local tax law, it is required to
withhold upon exercise of the Option; and

          (e)  In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option.

Section 4.4.  Conditions to Issuance of Stock Certificates
              --------------------------------------------

          The shares of stock deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued shares or
issued shares which have 

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

          (a)  The obtaining of any approval or other clearance from any state
or federal governmental agency which the Company shall, in its absolute
discretion, determine to be necessary or advisable; and

          (b)  The payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (c)  The lapse of such reasonable period of time following the
exercise of the Option as the Company may from time to time establish for
reasons of administrative convenience.

Section 4.5.  Rights as Shareholder
              ---------------------

          The holder of the Option shall not be, nor have any of the rights or

representing such shares shall have been issued by the Company to such holder.

for any action, determination or interpretation made in good faith with respect
to the Option.

Section 5.2.  Option Not Transferable
              -----------------------

          Neither the Option nor any interest or right therein or part thereof
shall be liable for the debts, contracts or engagements of the Optionee or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and
distribution.

shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such 

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

               (1) Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

               (2) For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

               (3) The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

               (4) If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b)  As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c)  None of the shares of the Company's stock purchased on exercise
of the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock evidencing shares 

                                       9
<PAGE>
 
of stock purchased on exercise of the Option shall bear an appropriate legend
referring to the transfer restrictions imposed by this Section 5.8 and to the

                              EXERCISE OF OPTION

Section 4.1.  Person Eligible to Exercise
              ---------------------------

          During the lifetime of the Optionee, only he may exercise the Option

empowered to do so under the Optionee's will or under the then applicable laws
of descent and distribution.

Section 4.2.  Partial Exercise
              ----------------

          Any exercisable portion of the Option or the entire Option, if then

ten (10) shares (or the minimum installment set forth in Section 3.1, if a

<PAGE>
 
Section 4.3.  Manner of Exercise
              ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

          (a) Notice in writing signed by the Optionee or the other person then
entitled to exercise the Option or portion, stating that the Option or portion
is thereby exercised, such notice complying with all applicable rules
established by the Company; and

          (b) Full payment (in cash or by check) for the shares with respect to
which such Option or portion is exercised; and

          (c) A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

          (d) Full payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (e) In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option.

Section 4.4.  Conditions to Issuance of Stock Certificates
              --------------------------------------------

          The shares of stock deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued shares or
issued shares which have 

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

          (a) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Company shall, in its absolute discretion,
determine to be necessary or advisable; and

          (b) The payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (c) The lapse of such reasonable period of time following the exercise
of the Option as the Company may from time to time establish for reasons of
administrative convenience.

for any action, determination or interpretation made in good faith with respect
to the Option.

Section 5.2.  Option Not Transferable
              -----------------------

          Neither the Option nor any interest or right therein or part thereof
shall be liable for the debts, contracts or engagements of the Optionee or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and

shares, by any holder of such 

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

               (1) Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

               (2) For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

               (3) The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

               (4) If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b) As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c) None of the shares of the Company's stock purchased on exercise of
the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock 

                                       9
<PAGE>
 
evidencing shares of stock purchased on exercise of the Option shall bear an
appropriate legend referring to the transfer restrictions imposed by this

that at some time prior to the effective date of such event this Option shall be
exercisable as to all the shares covered hereby, notwithstanding that this

however, that this acceleration of exercisability shall not take place if:

          (a) This Option becomes unexercisable under Section 3.3 prior to said

          (b) In connection with such an event, provision is made for an

                              EXERCISE OF OPTION

Section 4.1.  Person Eligible to Exercise
              ---------------------------

          During the lifetime of the Optionee, only he may exercise the Option

Section 3.3, be exercised by his personal representative or by any person
empowered to do so under the Optionee's will or under the then applicable laws
of descent and distribution.

Section 4.2.  Partial Exercise
              ----------------

          Any exercisable portion of the Option or the entire Option, if then
wholly exercisable, may be exercised in whole or in part at any time prior to
the time when the Option or portion thereof becomes unexercisable under Section

ten (10) shares (or the minimum installment set forth in Section 3.1, if a

<PAGE>
 
Section 4.3.  Manner of Exercise
              ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

          (a) Notice in writing signed by the Optionee or the other person then
entitled to exercise the Option or portion, stating that the Option or portion
is thereby exercised, such notice complying with all applicable rules
established by the Company; and

          (b) Full payment (in cash or by check) for the shares with respect to
which such Option or portion is exercised; and

          (c) A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

          (d) Full payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (e) In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option.

Section 4.4.  Conditions to Issuance of Stock Certificates
              --------------------------------------------

          The shares of stock deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued shares or
issued shares which have 

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

          (a) The obtaining of any approval or other clearance from any state or
federal governmental agency which the Company shall, in its absolute discretion,
determine to be necessary or advisable; and

          (b) The payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (c) The lapse of such reasonable period of time following the exercise
of the Option as the Company may from time to time establish for reasons of
administrative convenience.

              ---------------------

for any action, determination or interpretation made in good faith with respect
to the Option.

Section 5.2.  Option Not Transferable
              -----------------------

          Neither the Option nor any interest or right therein or part thereof
shall be liable for the debts, contracts or engagements of the Optionee or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and
distribution.

Section 5.8.  Restrictions on Transfer of Shares
              ----------------------------------

          (a) There can be no valid transfer (as hereinafter defined) of any
shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such 

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

               (1) Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

               (2) For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

               (3) The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

               (4) If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b) As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c) None of the shares of the Company's stock purchased on exercise of
the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock evidencing shares 

                                       9
<PAGE>
 
of stock purchased on exercise of the Option shall bear an appropriate legend
referring to the transfer restrictions imposed by this Section 5.8 and to the

              --------------------------

          The installments provided for in Section 3.1 are cumulative. Each such
installment which becomes exercisable pursuant to Section 3.1 shall remain
exercisable until it becomes unexercisable under Section 3.3.

Section 3.3.  Expiration of Option
              --------------------

          The Option may not be exercised to any extent by anyone after the
first to occur of the following events:

          (a)  The expiration of ten (10) years from the date the Option was
granted; or

          (b)  The time of the Optionee's Termination of Employment unless such
Termination of Employment results from his death, his retirement or his
disability; or

                                       4
<PAGE>
 
          (c)  The expiration of three (3) months from the date of the
Optionee's Termination of Employment by reason of his disability; or

          (d)  The expiration of three (3) months from the date of the
Optionee's death.

Section 3.4.  Acceleration of Exercisability
              ------------------------------

          In the event of the merger or consolidation of the Company with or
into another corporation, or the acquisition by another corporation or person of
all or substantially all of the Company's assets or eighty percent (80%) or more
of the Company's then outstanding voting stock, or the liquidation or
dissolution of the Company, the Company may, in its absolute discretion and upon
such terms and conditions as it deems appropriate, provide prior to such event,
that at some time prior to the effective date of such event this Option shall be
exercisable as to all the shares covered hereby, notwithstanding that this
Option may not yet have become fully exercisable under Section 3.1(a); provided,
however, that this acceleration of exercisability shall not take place if:

          (a)  This Option becomes unexercisable under Section 3.3 prior to said
effective date; or

          (b)  In connection with such an event, provision is made for an
assumption of this Option or a substitution therefor of a new option by an
employer corporation or a parent or subsidiary of such corporation; or

          (c)  The contemplated corporate transaction is not consummated; and
provided, further, that nothing in this Section 3.4 shall make this Option
exercisable if it is otherwise unexercisable by reason of Section 5.6.

                                  ARTICLE IV.
                              EXERCISE OF OPTION

Section 4.1.  Person Eligible to Exercise
              ---------------------------

          During the lifetime of the Optionee, only he may exercise the Option
or any portion thereof. After the death of the Optionee, any exercisable portion
of the Option may, prior to the time when the Option becomes unexercisable under
Section 3.3, be exercised by his personal representative or by any person
empowered to do so under the Optionee's will or under the then applicable laws
of descent and distribution.

Section 4.2.  Partial Exercise
              ----------------

          Any exercisable portion of the Option or the entire Option, if then
wholly exercisable, may be exercised in whole or in part at any time prior to
the time when the Option or portion thereof becomes unexercisable under Section
3.3; provided, however, that each partial exercise shall be for not less than
ten (10) shares (or the minimum installment set forth in Section 3.1, if a
smaller number of shares) and shall be for whole shares only.

                                       5
<PAGE>
 
Section 4.3.  Manner of Exercise
              ------------------

          The Option, or any exercisable portion thereof, may be exercised
solely by delivery to the Chairman or his office of all of the following prior
to the time when the Option or such portion becomes unexercisable under Section
3.3:

          (a)  Notice in writing signed by the Optionee or the other person then
entitled to exercise the Option or portion, stating that the Option or portion
is thereby exercised, such notice complying with all applicable rules
established by the Company; and

          (b)  Full payment (in cash or by check) for the shares with respect to
which such Option or portion is exercised; and

          (c)  A bona fide written representation and agreement, in a form
satisfactory to the Company, signed by the Optionee or other person then
entitled to exercise such Option or portion, stating that the shares of stock
are being acquired for his own account, for investment and without any present
intention of distributing or reselling said shares or any of them except as may
be permitted under the Securities Act and then applicable rules and regulations
thereunder, and that the Optionee or other person then entitled to exercise such
Option or portion will indemnify the Company against and hold it free and
harmless from any loss, damage, expense or liability resulting to the Company if
any sale or distribution of the shares by such person is contrary to the
representation and agreement referred to above. The Company may, in its absolute
discretion, take whatever additional actions it deems appropriate to insure the
observance and performance of such representation and agreement and to effect
compliance with the Securities Act and any other federal or state securities
laws or regulations. Without limiting the generality of the foregoing, the
Company may require an opinion of counsel acceptable to it to the effect that
any subsequent transfer of shares acquired on an Option exercise does not
violate the Securities Act, and may issue stop-transfer orders covering such
shares. Share certificates evidencing stock issued on exercise of this Option
shall bear an appropriate legend referring to the provisions of this subsection
(c) and the agreements herein. The written representation and agreement referred
to in the first sentence of this subsection (c) shall, however, not be required
if the shares to be issued pursuant to such exercise have been registered under
the Securities Act, and such registration is then effective in respect of such
shares; and

          (d)  Full payment to the Company (or other employer corporation) of
all amounts which, under federal, state or local tax law, it is required to
withhold upon exercise of the Option; and

          (e)  In the event the Option or portion shall be exercised pursuant to
Section 4.1 by any person or persons other than the Optionee, appropriate proof
of the right of such person or persons to exercise the Option.

Section 4.4.  Conditions to Issuance of Stock Certificates
              --------------------------------------------

          The shares of stock deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued shares or
issued shares which have 

                                       6
<PAGE>
 
then been reacquired by the Company. Such shares shall be fully paid and
nonassessable. The Company shall not be required to issue or deliver any
certificate or certificates for shares of stock purchased upon the exercise of
the Option or portion thereof prior to fulfillment of all of the following
conditions:

          (a)  The obtaining of any approval or other clearance from any state
or federal governmental agency which the Company shall, in its absolute
discretion, determine to be necessary or advisable; and

          (b)  The payment to the Company (or other employer corporation) of all
amounts which, under federal, state or local tax law, it is required to withhold
upon exercise of the Option; and

          (c)  The lapse of such reasonable period of time following the
exercise of the Option as the Company may from time to time establish for
reasons of administrative convenience.

Section 4.5.  Rights as Shareholder
              ---------------------

          The holder of the Option shall not be, nor have any of the rights or
privileges of, a shareholder of the Company in respect of any shares purchasable
upon the exercise of any part of the Option unless and until certificates
representing such shares shall have been issued by the Company to such holder.

                                  ARTICLE V.
                               OTHER PROVISIONS

Section 5.1.  Administration
              --------------

          The Company shall have the power to interpret this Agreement. All
actions taken and all interpretations and determinations made by the Company in
good faith shall be final and binding upon the Optionee, the Company and all
other interested persons. No member of the Company shall be personally liable
for any action, determination or interpretation made in good faith with respect
to the Option.

Section 5.2.  Option Not Transferable
              -----------------------

          Neither the Option nor any interest or right therein or part thereof
shall be liable for the debts, contracts or engagements of the Optionee or his
successors in interest or shall be subject to disposition by transfer,
alienation, anticipation, pledge, encumbrance, assignment or any other means
whether such disposition be voluntary or involuntary or by operation of law by
judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect; provided, however, that this Section 5.2
shall not prevent transfers by will or by the applicable laws of descent and
distribution.

                                       7

Section 5.3.  Shares to Be Reserved

and keep available such number of shares of stock as will be sufficient to
satisfy the requirements of this Agreement.

Section 5.4.  Notices
              -------

          Any notice to be given under the terms of this Agreement to the
Company shall be addressed to the Company in care of its Chairman, and any
notice to be given to the Optionee shall be addressed to him at the address
given beneath his signature hereto. By a notice given pursuant to this Section
5.4, either party may hereafter designate a different address for notices to be
given to him. Any notice which is required to be given to the Optionee shall, if
the Optionee is then deceased, be given to the Optionee's personal
representative if such representative has previously informed the Company of his
status and address by written notice under this Section 5.4. Any notice shall be
deemed duly given when enclosed in a properly sealed envelope or wrapper
addressed as aforesaid, deposited (with postage prepaid) in a post office or
branch post office regularly maintained by the United States Postal Service.

Section 5.5.  Titles
              ------

          Titles are provided herein for convenience only and are not to serve
as a basis for interpretation or construction of this Agreement.

Section 5.6.  Construction
              ------------

          This Agreement shall be administered, interpreted and enforced under
the laws of the State of California.

Section 5.7.  Conformity to Securities Laws
              -----------------------------

          The Optionee acknowledges that this Agreement is intended to conform
to the extent necessary with all provisions of the Securities Act and the
Exchange Act, the California Corporations Code and any and all regulations and
rules promulgated by the Securities and Exchange Commission and/or the
Corporations Commissioner thereunder, including without limitation Rule 16b-3.
Notwithstanding anything herein to the contrary, this Agreement shall be
administered, and the Option is granted and may be exercised, only in such a
manner as to conform to such laws, rules and regulations. To the extent
permitted by applicable law, this Agreement shall be deemed amended to the
extent necessary to conform to such laws, rules and regulations.

Section 5.8.  Restrictions on Transfer of Shares
              ----------------------------------

          (a)  There can be no valid transfer (as hereinafter defined) of any
shares of stock purchased on exercise of the Option, or any interest in such
shares, by any holder of such 

                                       8
<PAGE>
 
shares or interests unless such transfer is solely for cash consideration and is
made in compliance with the following provisions:

               (1)  Before there can be a valid transfer of any shares or any
     interest therein, the record holder of the shares to be transferred (the
     "Offered Shares") shall give written notice (by registered or certified
     mail) to the Company. Such notice shall specify the identity of the
     proposed transferee, the cash price offered for the Offered Shares by the
     proposed transferee and the other terms and conditions of the proposed
     transfer. The date such notice is mailed shall be hereinafter referred to
     as the "notice date" and the record holder of the Offered Shares shall be
     hereinafter referred to as the "Offeror."

               (2)  For a period of thirty (30) calendar days after the notice
     date, the Company shall have the option to purchase all (but not less than
     all) of the Offered Shares at the purchase price and on the terms set forth
     in subsection (a)(3) of this Section 5.8. This option shall be exercisable
     by the Company by mailing (by registered or certified mail) written notice
     of exercise to the Offeror prior to the end of said thirty (30) days.

               (3)  The price at which the Company may purchase the Offered
     Shares pursuant to the exercise of such option shall be the cash price
     offered for the Offered Shares by the proposed transferee (as set forth in
     the notice required under subsection (a)(1) of this Section 5.8). The
     Company's notice of exercise of such option shall be accompanied by full
     payment for the Offered Shares and, upon such payment by the Company, the
     Company shall acquire full right, title and interest to all of the Offered
     Shares.

               (4)  If, and only if, the option given pursuant to subsection
     (a)(2) of this Section 5.8 is not exercised, the transfer proposed in the
     notice given pursuant to subsection (a)(1) of this Section 5.8 may take
     place; provided, however, that such transfer must, in all respects, be
     exactly as proposed in said notice except that such transfer may not take
     place either before the tenth (10th) calendar day after the expiration of
     said thirty-day option exercise period or after the ninetieth (90th)
     calendar day after the expiration of said thirty-day option exercise
     period, and if such transfer has not taken place prior to said ninetieth
     (90th) day, such transfer may not take place without once again complying
     with subsection (a) of this Section 5.8.

          (b)  As used in this Section 5.8, the term "transfer" means any sale,
encumbrance, pledge, gift or other form of disposition or transfer of shares of
the Company's stock or any legal or equitable interest therein; provided,
however, that the term "transfer" does not include a transfer of such shares or
interests by will or by the applicable laws of descent and distribution or a
gift of such shares if the donee agrees to be bound by the provisions of this
Section 5.8.

          (c)  None of the shares of the Company's stock purchased on exercise
of the Option shall be transferred on the Company's books nor shall the Company
recognize any such transfer of any such shares or any interest therein unless
and until all applicable provisions of this Section 5.8 have been complied with
in all respects. The certificates of stock evidencing shares

                                       9
<PAGE>
 
of stock purchased on exercise of the Option shall bear an appropriate legend
referring to the transfer restrictions imposed by this Section 5.8 and to the
repurchase option provided for in Section 5.8.

Section 5.9.  Complete Agreement

        -----------------------------------

     (a) Basic Transaction.
         --------------------

          (i)  On and subject to the terms and conditions of this Agreement, the
     Buyer agrees to purchase from the Seller, and the Seller agrees to sell,
     transfer, convey and deliver to the Buyer, all of the Acquired Assets on
     the Closing Date for the consideration specified in (S)2(b) below.

          (ii) On and subject to the terms and conditions of this Agreement, the
     Buyer agrees to assume and become responsible for all of the Assumed
     Liabilities on the Closing Date.  The Buyer will not assume or have any
     responsibility, however, with respect to any other obligation or Liability
     of the Seller not included within the definition of Assumed Liabilities.

     (b) Purchase Price. On an subject to the terms and conditions of this
         ---------------                                                  
Agreement, as consideration for the sale of all of the Acquired Assets the Buyer
shall assume the Assumed Liabilities on the Closing Date and shall pay to Seller
the following additional consideration, in the aggregate amounts, at the
following times (the "Purchase Price"):

          (i)  ONE MILLION DOLLARS ($1,000,000.00) (the "Cash") by wire transfer
     or delivery of other immediately available funds on the Closing Date;

          (ii) subordinated promissory notes from the Buyer (the "Buyer Notes")
     on the terms and conditions set forth in and in the form of Exhibits A, B
     and C attached hereto in the aggregate principal amount of FOUR HUNDRED
     THOUSAND DOLLARS ($400,000.00) on the Closing Date;

                                       7
<PAGE>
 
          (iii) subordinated promissory notes from the Buyer convertible into
     shares of Buyer Stock (the "Convertible Notes") on the terms and conditions
     set forth in and in the form of Exhibits D, E and F attached hereto in the
     aggregate principal amount of FIVE HUNDRED THIRTY SEVEN THOUSAND TWO
     HUNDRED FIFTY FIVE DOLLARS AND SEVENTY TWO CENTS  ($537,255.72) on the
     Closing Date; and

          (iv)  an additional sum based on the combined pre-tax income of the
     Seller from January 1, 1998 through the Closing Date and the Digital
     Networks Division from the Closing Date through December 31, 1998 based on
     the formula set forth in (S)2(c) below (the "Earn Out").

     (c) The Earn Out Formula. As part of the Purchase Price, the Buyer shall
         ---------------------                                               
pay to Seller the Earn Out based on the following:

          (i)   If the pre-tax income of the Seller from January 1, 1998 through
     the Closing Date when combined with the pre-tax income of the Digital
     Networks Division from the Closing Date through December 31, 1998 is more
     than THREE HUNDRED THOUSAND DOLLARS ($300,000.00) (the "Threshold Amount"),
     the Buyer shall pay to the Seller an amount equal to TWO DOLLARS AND TEN
     CENTS ($2.10) for each dollar by which the combined pre-tax income exceeds
     the Threshold Amount up to a maximum Earn Out of FIVE HUNDRED THOUSAND
     DOLLARS ($500,000.00). The Earn Out, if any, shall be payable to the Seller
     in three (3) equal installments on May 31, 1999, June 30, 1999 and July 31,
     1999.  If the combined pre-tax income is not greater than the Threshold
     Amount, no Earn Out shall be due or payable to the Seller.

          (ii)  In determining the pre-tax income of the Digital Networks
     Division from the Closing Date through December 31, 1998, the Digital
     Networks Division shall, for accounting purposes, be treated as a separate
     entity and shall not be charged with any overhead or other allocations from
     the Buyer except for those expenses which Seller would have incurred in the
     ordinary course of its business (e.g., rent, payroll, benefits etc.) had
     the transactions contemplated by this Agreement not occurred.

     (d) Other Provisions With Respect to the Notes.
         -------------------------------------------

          (i)   The Buyer Notes shall bear interest at the Applicable Rate and
     be payable to the Seller on or before six (6) months from the Closing Date.

          (ii)  At any time after the Closing Date and prior to December 31,
     1999 (the "Final Conversion Date"), if there has been no Initial Public
     Offering of the Buyer's Stock the Seller shall have the right, on written
     notice to the Buyer, to convert the Convertible Notes into Buyer Stock (the
     "Conversion Option"). If there has been an

                                       8
<PAGE>
 
     Initial Public Offering of the Buyer's Stock prior to the Final Conversion
     Date, the Convertible Notes shall automatically be cancelled and converted
     into Buyer Stock on the date immediately following the Initial Public
     Offering (the "Mandatory Conversion"). If the Seller timely elects the
     Conversion Option or there is a Mandatory Conversion, each Convertible Note
     shall be exchanged for FIVE THOUSAND NINE HUNDRED EIGHTY TWO (5,982) shares
     of Buyer common stock (or 17,946 shares in the aggregate). Any Buyer Stock
     issued pursuant to either conversion shall be subject to the same
     limitations and restrictions as the common stock held by the other
     principal shareholders of the Buyer. If there has been no Initial Public
     Offering of the Buyer's Stock prior to the Final Conversion Date and the
     Seller fails to timely exercise the Conversion Option, the Convertible
     Notes shall be paid in six (6) equal monthly installments commencing on the
     first business day of January 2000. The Convertible Notes shall bear
     interest at the annual rate of seven percent (7%).

          (iii) Buyer expressly reserves against the Seller (and the Seller
     Stockholders to the extent any of the Notes are transferred to Seller
     Stockholders) the right to offset against any and all sums payable under
     any of the Notes an amount equal to any and all damages sustained by the
     Buyer by reason of any default by the Seller or the breach of any
     representations, warranties or covenants of the Seller under this
     Agreement.

     (e) Allocation of Amounts Paid. The Parties agree to allocate the Purchase
         ---------------------------                                           
Price (and all other capitalizable costs) among the Acquired Assets for all
purposes (including financial accounting and tax purposes) based on the book
value of the Acquired Assets as of the Closing Date with the difference between
the book value of the Acquired Assets as of the Closing Date and the aggregate
of the consideration set forth in (S)2(b)(i)-(iv) and the value of the Assumed
Liabilities as of the Closing Date being characterized as "goodwill."  The
parties shall agree on the book value of the Acquired Assets and the Assumed
Liabilities as of the Closing Date within thirty (30) days after the Closing
Date.

     (f) Employment Agreements. As additional consideration for and as a
         ----------------------                                         
condition to the Buyer's payment of  the Purchase Price, each of the Seller
Stockholders shall enter into an Employment Agreement with the Buyer on terms
and conditions satisfactory to the Buyer in the form of Exhibits G-1, G-2 and G-
3 attached hereto.

     (g) Agreement with Seller Stockholders. As further consideration for and as
         -----------------------------------                                    
a condition to the Buyer's payment of the Purchase Price, each of the Seller
Stockholders shall enter into the Agreement with Seller Stockholders with the
Buyer in the form of Exhibit H attached hereto.

Seller Stockholders.  As consideration for its management services, Buyer shall
be entitled to receive all of the net profits earned by the Seller during the
Interim Period (the "Management Fee") subject to the condition that the Buyer
fulfills its obligations under this Agreement.  If Buyer fails to pay the Cash

     reasonably satisfactory to the Indemnified Party so long as (A) the
     Indemnifying Party notifies the Indemnified Party in writing within 30 days
     after the Indemnified Party has given notice of the Third Party Claim that
     the Indemnifying Party will indemnify the Indemnified Party from and
     against the entirety of any Adverse Consequences the Indemnified Party may
     suffer resulting from, arising out of, relating to, in the nature of, or
     caused by the Third Party Claim, (B) the Indemnifying Party provides the
     Indemnified Party with evidence reasonably acceptable to the Indemnified
     Party that the Indemnifying Party will have the financial resources to
     defend against the Third Party Claim and fulfill its indemnification
     obligations hereunder, (C) the Third Party Claim involves only money
     damages and does not seek an injunction or other equitable relief, (D)
     settlement of, or an adverse judgment with respect to, the Third Party
     Claim is not, in the good faith judgment of the Indemnified Party, likely
     to establish a precedential custom or practice [materially] adverse to the
     continuing business interests of the Indemnified Party, and (E) the
     Indemnifying Party conducts the defense of the Third Party Claim actively
     and diligently.

          (iii) So long as the Indemnifying Party is conducting the defense of
     the Third Party Claim in accordance with (S)6 (d)(ii) above, (A) the
     Indemnified Party may retain separate co-counsel at its sole cost and
     expense and participate in the defense of the Third Party Claim, (B) the
     Indemnified Party will not consent to the entry of any judgment or enter
     into any settlement with respect to the Third Party Claim without the prior
     written consent of the Indemnifying Party, and (C) the Indemnifying Party
     will not consent to the entry of any judgment or enter into any settlement
     with respect to the Third Party Claim without the prior written consent of
     the Indemnified Party (not to be withheld unreasonably). In the event any
     of the conditions in (S)6(d)(ii) above is or becomes unsatisfied, however,
     (A) the Indemnified Party may defend against, and consent to the entry of
     any judgment or enter into any settlement with respect to, the Third Party
     Claim in any manner it reasonably may deem appropriate (and the Indemnified
     Party need not consult with, or obtain any consent from, any Indemnifying
     Party in connection therewith), (B) the Indemnifying Parties will reimburse
     the Indemnified Party promptly and periodically for the costs of defending
     against the 

                                       32
<PAGE>
 
     Third Party Claim (including reasonable attorneys' fees and expenses), and
     (C) the Indemnifying Parties will remain responsible for any Adverse
     Consequences the Indemnified Party may suffer resulting from, arising out
     of, relating to, in the nature of, or caused by the Third Party Claim to
     the fullest extent provided in this (S)6.

     (e) Determination of Adverse Consequences. The Parties shall take into
         --------------------------------------                            
account the time cost of money (using the Applicable Rate as the discount rate)
in determining Adverse Consequences for purposes of this (S)4. All
indemnification payments under this (S)6 shall be deemed adjustments to the
Purchase Price.

     (f) Recoupment Under The Notes. The Buyer shall have the option of
         ---------------------------                                   
recouping all or any part of any Adverse Consequences it may suffer (in lieu of
or in addition to seeking any indemnification to which it is entitled under this
(S)6) by notifying the Seller that the Buyer is reducing the principal amount
outstanding under any of the Notes. This shall affect the timing and amount of
payments required under the Notes in the same manner as if the Buyer had made a
permitted prepayment (without premium or penalty) thereunder.

     (g) Other Indemnification Provisions. The foregoing indemnification
         ---------------------------------                              
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of representation,
warranty, or covenant. The Seller hereby agrees that it will not make any claim
for indemnification against any of the Buyer and its Subsidiaries by reason of
the fact that it was an agent of the Seller or was serving at the request of any
such entity as a partner, trustee, director, officer, employee, or agent of
another entity (whether such claim is for judgments, damages, penalties, fines,
costs, amounts paid in settlement, losses, expenses, or otherwise and whether
such claim is pursuant to any statute, charter document, bylaw, agreement, or
otherwise) with respect to any action, suit, proceeding, complaint, claim, or
demand brought by the Buyer against the Seller (whether such action, suit,
proceeding, complaint, claim, or demand is pursuant to this Agreement,
applicable law, or otherwise).

     7. Miscellaneous.

release or make any public announcement relating to the subject matter of this

                                       33
<PAGE>
 
which case the disclosing Party will use its reasonable best efforts to advise
the other Parties prior to making the disclosure).

     (c) No Third-Party Beneficiaries. This Agreement shall not confer any
         -----------------------------                                    
rights or remedies upon any Person other than the Parties and their respective

inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of his
rights, interests, or obligations hereunder without the prior written approval

Any Party may send any notice, request, demand, claim, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,
telecopy, telex, ordinary mail, or electronic mail), but no such notice,
request, demand, claim, or other communication shall be deemed to have been duly
given unless and until it actually is received by the intended recipient. Any
Party may change the address to which notices, requests, demands, claims, and
other communications hereunder are to be delivered by giving the other Parties
notice in the manner herein set forth.

     (i) Governing Law. This Agreement shall be governed by and construed in
         -------------                                                      
accordance with the domestic laws of the State of California without giving
effect to any choice or conflict of law provision or rule (whether of the State
of California or any other jurisdiction) that would cause the application of the
laws of any other jurisdiction.

     (j) Amendments and Waivers. No amendment of any provision of this Agreement
         -----------------------                                                
shall be valid unless the same shall be in writing and signed by the Buyer and
the Seller. No waiver by any Party of any default, misrepresentation, or breach
of warranty or covenant hereunder, whether intentional or not, shall be deemed
to extend to any prior or subsequent default, 

                                       35
<PAGE>
 
misrepresentation, or breach of warranty or covenant hereunder or affect in any
way any rights arising by virtue of any prior or subsequent such occurrence.

     (k) Severability. Any term or provision of this Agreement that is invalid
         -------------                                                        
or unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

     (l) Expenses. Each of the Parties will bear his own costs and expenses
         ---------                                                         
(including legal fees and expenses) incurred in connection with this Agreement
and the transactions contemplated hereby. The Seller also agrees that it has not
paid any amount to any third party, and will not pay any amount to any third
party until after the Closing, with respect to any of the costs and expenses of
the Seller and the Seller Stockholders (including any of their legal fees and
expenses) in connection with this Agreement or any of the transactions
contemplated hereby.

     (m) Construction. The Parties have participated jointly in the negotiation

and drafting of this Agreement. In the event an ambiguity or question of intent
or interpretation arises, this Agreement shall be construed as if drafted
jointly by the Parties and no presumption or burden of proof shall arise
favoring or disfavoring any Party by virtue of the authorship of any of the
provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty, and covenant contained herein shall have
independent significance. If any Party has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there
exists another representation, warranty, or covenant relating to the same
subject matter (regardless of the relative levels of specificity) which the
Party has not breached shall not detract from or mitigate the fact that the
Party is in breach of the first representation, warranty, or covenant.

     (n) Incorporation of Exhibits, Annexes, and Schedules. The Exhibits,
         --------------------------------------------------              
Annexes, and Schedules identified in this Agreement are incorporated herein by

     (o) Specific Performance. Each of the Parties acknowledges and agrees that
         ---------------------                                                 
the other Parties would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Parties shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the
Parties and the matter (subject to 

                                       36
<PAGE>
 
the provisions set forth in (S)7(p) below), in addition to any other remedy to
which they may be entitled, at law or in equity.

     (p) Submission to Jurisdiction. Each of the Parties submits to the

jurisdiction of any state or federal court sitting in Orange County, California,
in any action or proceeding arising out of or relating to this Agreement and
agrees that all claims in respect of the action or proceeding may be heard and
determined in any such court. Each Party also agrees not to bring any action or
proceeding arising out of or relating to this Agreement in any other court. Each
of the Parties waives any defense of inconvenient forum to the maintenance of
any action or proceeding so brought and waives any bond, surety, or other
security that might be required of any other Party with respect thereto.

     (q) Bulk Transfer Laws. The Buyer acknowledges that the Seller will not

comply with the provisions of any bulk transfer laws of any jurisdiction in
connection with the transactions contemplated by this Agreement.

     IN WITNESS WHEREOF, the Parties hereto have executed this Agreement on [as
of] the date first above written.

     Taxes for any period for which Tax Returns have been filed. There is no
     dispute or claim concerning any Tax Liability of the Company either (A)
     claimed or raised by any authority in writing or (B) as to which any of the
     Sellers and the directors and officers (and employees responsible for Tax
     matters) of the Company has Knowledge based upon personal contact with any

     by contract, or otherwise.

          (vi)  The unpaid Taxes of the Company (A) did not, as of the Most
     Recent Fiscal Month End, exceed the reserve for Tax Liability (rather than

None of the Sellers and the directors and officers (and employees with
responsibility for employment matters) of the Company has any Knowledge of any
organizational effort presently being made or threatened by or on behalf of any
labor union with respect to employees of the Company.

     (x) Employee Benefits. The Company does not maintain any Employee Benefit
         ------------------                                                   
Plans. (S)4(x) of the Disclosure Schedule lists each Employee Benefit Plan to
which the Company contributes.
 
     (y) Guaranties. Except as set forth in (S)4(y) of the Disclosure Schedule,
         -----------                                                           
the Company is not a guarantor or otherwise liable for any Liability or

     Without limiting the generality of the preceding sentence, to the Sellers'

     (aa) Disclosure. The representations and warranties contained in this (S)4
          -----------                                                          
do not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements and information
contained in this (S)4 not misleading.

     5. Post-Closing Covenants. The Parties agree as follows with respect to the
        -----------------------                                                 
period following the Closing.

     (a) General. In case at any time after the Closing Date any further action
         --------                                                              
is necessary or desirable to carry out the purposes of this Agreement, each of
the Parties will take such further action (including the execution and delivery
of such further instruments and documents) as any other Party reasonably may
request, all at the sole cost and expense of the requesting Party (unless the
requesting Party is entitled to indemnification therefor under (S)6 below). The
Sellers acknowledge and agree that from and after the Effective Date the Buyer
will be entitled to possession of all documents, books, records (including Tax
records), agreements, and financial data of any sort relating to the Company.
Buyer shall make such books and records available to Sellers for preparation of
the Company's 1997 federal income tax return and 1998 Texas franchise tax return
and otherwise as reasonably requested by Sellers.

     (b) Litigation Support. In the event and for so long as any Party actively
         -------------------                                                   
is contesting or defending against any action, suit, proceeding, hearing,
investigation, charge, complaint, claim, or demand in connection with (i) any
transaction contemplated under this Agreement or (ii) any fact, situation,
circumstance, status, condition, activity, practice, plan, occurrence, event,
incident, action, failure to act, or transaction on or prior to the Effective
Date involving the Company, each of the other Parties will cooperate with him or
it and his or its counsel in the contest or defense, make available their
personnel, and provide such testimony and access to their books and records as
shall be necessary in connection with the contest or defense, all at the sole
cost and expense of the contesting or defending Party (unless the contesting or
defending Party is entitled to indemnification therefor under (S)6 below).

     (c) Transition. None of the Sellers will take any action that is designed
         -----------                                                          
or intended to have the effect of discouraging any lessor, licensor, customer,
supplier, or other business 

                                       19
<PAGE>
 
associate of the Company from maintaining the same business relationships with
the Company after the Closing as it maintained with the Company prior to the
Closing. Each of the Sellers will refer all customer inquiries relating to the
businesses of the Company to the Buyer from and after the Closing.

     (d) Covenant Not to Compete. Sellers each acknowledge and agree that they
         ------------------------                                             
have technical expertise associated with the business of the Company and are
well known in the presentation/communication industry.  In addition, the Sellers
have valuable business contacts with clients and potential clients of the
Company and with professionals in the presentation/communication industry.  The
Company's reputation and good will are an integral part of business success
throughout the areas where it conducts its business.  If Sellers deprive Buyer
of the Company's goodwill or in any manner use their reputation and goodwill in
competition with the Company, Buyer will be deprived of the benefits it has
bargained for pursuant to this Agreement.  Since Sellers have the ability to
compete with the Company in the operation of the Company's business, Buyer,
therefore, desires that the Sellers enter into this covenant not to compete.
But for Sellers' entry into this covenant not to compete, Buyer would not enter
into this Agreement.  It is, therefore, understood and agreed that by the sale
of their Company Stock, the Sellers have transferred to Buyer all of their
business goodwill in the Company. Sellers, therefore, agree that for a period of
three (3) years from the Closing (the "Term"), Sellers shall not, without
Buyer's prior written consent (which may be given or withheld in Buyer's sole
and absolute discretion), directly or indirectly,

          (i)   own, manage, join, operate or control, or participate in the
     ownership, management, operation or control of, or be connected as a
     director, officer, employee, partner, consultant or otherwise with, or
     permit their names to be used by or in connection with, any profit or non-
     profit business or organization which sells, distributes or markets
     products, goods or equipment which, directly or indirectly compete with the
     Company's business, as conducted by the Company immediately prior to the
     Closing (audio-visual systems sales and installation) in the state of
     Texas; provided, however, the following activities shall not be a violation
     of the terms of this non-compete provision: (x) the sale by Alford Media
     Services, Inc. of used rental equipment in customary distribution channels,
     and (y) the sale, merger, consolidation or other business combination
     between Alford Media Services, Inc. and a company which has a division
     which is involved in audio-visual system sales and installation.

          (ii)  call on or solicit or divert or take away from the Company
     and/or the Buyer (including without limitation by divulging to any
     competitor or potential competitor of the Company and/or the Buyer) any
     Person, firm or corporation or other entity who is or which at the Closing
     was a customer of the Company and/or the Buyer or whose identity is known
     to the Sellers at the Closing as one whom the Company and/or the Buyer
     intends to solicit; provided, however, it is acknowledged that Alford Media
     Services, 

                                       20
<PAGE>
 
     Inc. and the Company have common customers and Alford Media Services,
     Inc.'s continued providing of audio-visual equipment rental and staging
     services to such common customers or the solicitation of other customers or
     potential customers of the Company for such services shall not be a
     violation of the terms of this non-compete provision; or

          (iii) hire or offer employment to or seek to hire or offer employment
     to any employee of the Company whose employment is continued by the Company
     after the Closing or any employee of any successor or affiliate of the
     Company, unless Buyer first terminates the employment of such employee or
     gives its written consent to such employment or offer of employment.

Sellers acknowledge that the provisions of this (S)5(d) are reasonable and
necessary to protect legitimate interests of Buyer.  Sellers further acknowledge
that any breach of this (S)5(d) by them will cause irreparable injury to Buyer
and the Company, for which the available remedies at law will not be adequate.
Accordingly, in the event of any such breach or threatened breach of any
provisions of this (S)5(d), in addition to any other remedy provided by law or
in equity, the Buyer and the Company shall be entitled to appropriate injunctive
relief and/or specific performance, in any court of competent jurisdiction,
restraining the Sellers from any such actual or threatened breach of this
section without posting bond or other security.  Sellers stipulate to the entry
against them of any temporary, preliminary or permanent injunction and agree not
to resist the Buyer's and/or the Company's application for such equitable
relief, except on the grounds that the acts or omissions alleged do not violate
any of the provisions of this section.  Sellers shall, in the event that any
injunctive relief or damages shall be granted to the Buyer and/or the Company,
pay all of the Buyer's and/or the Company's reasonable costs and expenses,
including attorneys' fees, incurred in obtaining such relief.  If the final
judgment of a court of competent jurisdiction declares that any term or
provision of this (S)5(d) is invalid or unenforceable, the Parties agree that
the court making the determination of invalidity or unenforceability shall have
the power to reduce the scope, duration, or area of the term or provision, to
delete specific words or phrases, or to replace any invalid or unenforceable
term or provision with a term or provision that is valid and enforceable and
that comes closest to expressing the intention of the invalid or unenforceable
term or provision, and this Agreement shall be enforceable as so modified after
the expiration of the time within which the judgment may be appealed.

     (e) Intellectual Property.  Buyer acknowledges and agrees that following
         ---------------------                                               
the Closing, the Company shall not be entitled to use certain Intellectual
Property previously used by the Company in the operation of its business, except
as herein provided.  Following the Closing, the Company shall not use any
trademark, service mark, trade name or logo previously used by the Company which
includes the name "Alford" or otherwise operate under any name including the
name "Alford;" provided, however, Buyer shall have ninety (90) days following
the Closing to change the name of the Company.  Following the Closing, the
Company shall 

                                       21
<PAGE>
 
have no rights to use the internal bid/processing system (computer software)
previously used by the Company (and licensed by Alford Media Services, Inc. from
a third party).

     (f)  Premises.  It is acknowledged and agreed that the Company shares space
          --------                                                              
with Alford Media Services, Inc. Buyer covenants and agrees to cause the company
to vacate such premises on or before July 1, 1998.

     (g)  Employee Benefit Plans.  It is acknowledged and agreed that the
          ----------------------                                         
Company's employees are covered under the group health insurance plan, and
participate in the 401(k) plan, maintained by Alford Media Services, Inc.  If
requested by Buyer,  Sellers agree to cause Alford Media Services, Inc. to
continue to provide coverage under its group health insurance plan for a period
of up to sixty (60) days following the Closing provided that the company
reimburses Alford Media Services, Inc. for such costs within ten (10) days of an
invoice therefor.  Buyer covenants and agrees to put in place similar employee
benefit plans for the Company's employees within sixty (60) days following
Closing.

     (h)  Future Equipment Purchases.  It is acknowledged and agreed that Alford
          --------------------------                                            
Media Services, Inc. may from time to time seek to purchase audio-visual
equipment from the Company and/or Buyer.  Buyer hereby covenants and agrees to
make such equipment available to Alford Media Services, Inc. for purchase upon
the same price and payment terms as Buyer and/or the Company make available to
its best customers and not to sell any such equipment to another customer for a
price less than that offered to Alford Media Services, Inc.

     6. Remedies for Breaches of This Agreement.
        ----------------------------------------

     (a)  Survival of Representations and Warranties.
          -------------------------------------------

All of the representations and warranties of the Parties contained in this
Agreement shall survive the Closing hereunder and continue in full force and
effect for a period of two (2) years from the Closing Date.

     (b)  Indemnification Provisions for Benefit of the Buyer.
          ----------------------------------------------------

          (i)   In the event any of the Sellers breaches (or in the event any
     third party alleges facts that, if true, would mean any of the Sellers has
     breached) any of their representations, warranties, and covenants contained
     in this Agreement and, if there is an applicable survival period pursuant
     to (S)6(a) above, provided that the Buyer makes a written claim for
     indemnification against any of the Sellers pursuant to (S)8(h) below within
     such survival period, then each of the Sellers agrees to indemnify the
     Buyer from and against the entirety of any Adverse Consequences the Buyer
     may suffer through and after the date of the claim for indemnification
     (including any Adverse 

                                       22
<PAGE>
 
     Consequences the Buyer may suffer after the end of any applicable survival
     period) resulting from, arising out of, relating to, in the nature of, or
     caused by the breach (or the alleged breach).

          (ii)  Each of the Sellers agrees to indemnify the Buyer from and
     against the entirety of any Adverse Consequences the Buyer may suffer
     resulting from, arising out of, relating to, in the nature of, or caused by
     any Liability of the Company (x) for any Taxes of the Company with respect
     to any Tax year or portion thereof ending on or before the Closing Date (or
     for any Tax year beginning before and ending after the Closing Date to the
     extent allocable (determined in a manner consistent with (S)7(c)) to the
     portion of such period beginning before and ending on the Closing Date), to
     the extent such Taxes are not reflected in the reserve for Tax Liability
     (rather than any reserve for deferred Taxes established to reflect timing
     differences between book and Tax income) shown on the face of the Most
     Recent Balance Sheet (rather than in any notes thereto), as such reserve is
     adjusted for the passage of time through the Closing Date in accordance
     with the past custom and practice of the Company in filing their Tax
     Returns, and (y) for the unpaid Taxes of any Person (other than the
     Company) under Reg. (S)1.1502-5 (or any similar provision of state, local,
     or foreign law), as a transferee or successor, by contract, or otherwise.

     (c) Indemnification Provisions for Benefit of the Sellers. In the event the
         ------------------------------------------------------                 
Buyer breaches (or in the event any third party alleges facts that, if true,
would mean the Buyer has breached) any of its representations, warranties, and
covenants contained herein, and, if there is an applicable survival period
pursuant to (S)6(a) above, provided that any of the Sellers makes a written
claim for indemnification against the Buyer pursuant to (S)8(h) below within
such survival period, then the Buyer agrees to indemnify each of the Sellers
from and against the entirety of any Adverse Consequences the Seller may suffer
through and after the date of the claim for indemnification (including any
Adverse Consequences the Seller may suffer after the end of any applicable
survival period) resulting from, arising out of, relating to, in the nature of,
or caused by the breach (or the alleged breach).

     (d) Matters Involving Third Parties.
         --------------------------------

          (i)   If any third party shall notify any Party (the "Indemnified
                                                               ------------
     Party") with respect to any matter (a "Third Party Claim") which may give
                                           -------------------                
     rise to a claim for indemnification against any other Party (the
     "Indemnifying Party") under this (S)6, then the Indemnified Party shall
     --------------------                                                   
     promptly notify each Indemnifying Party thereof in writing; provided,
                                                                 ---------
     however, that no delay on the part of the Indemnified Party in notifying
     -------                                                                 
     any Indemnifying Party shall relieve the Indemnifying Party from any
     obligation hereunder unless (and then solely to the extent) the
     Indemnifying Party thereby is prejudiced.

                                       23
<PAGE>
 
          (ii)  Any Indemnifying Party will have the right to defend the
     Indemnified Party against the Third Party Claim with counsel of its choice
     reasonably satisfactory to the Indemnified Party so long as (A) the
     Indemnifying Party notifies the Indemnified Party in writing within 30 days
     after the Indemnified Party has given notice of the Third Party Claim that
     the Indemnifying Party will indemnify the Indemnified Party from and
     against the entirety of any Adverse Consequences the Indemnified Party may
     suffer resulting from, arising out of, relating to, in the nature of, or
     caused by the Third Party Claim, (B) the Indemnifying Party provides the
     Indemnified Party with evidence reasonably acceptable to the Indemnified
     Party that the Indemnifying Party will have the financial resources to
     defend against the Third Party Claim and fulfill its indemnification
     obligations hereunder, (C) the Third Party Claim involves only money
     damages and does not seek an injunction or other equitable relief, (D)
     settlement of, or an adverse judgment with respect to, the Third Party
     Claim is not, in the good faith judgment of the Indemnified Party, likely
     to establish a precedential custom or practice materially adverse to the
     continuing business interests of the Indemnified Party, and (E) the
     Indemnifying Party conducts the defense of the Third Party Claim actively
     and diligently.

          (iii) So long as the Indemnifying Party is conducting the defense of
     the Third Party Claim in accordance with (S)6 (d)(ii) above, (A) the
     Indemnified Party may retain separate co-counsel at its sole cost and
     expense and participate in the defense of the Third Party Claim, (B) the
     Indemnified Party will not consent to the entry of any judgment or enter
     into any settlement with respect to the Third Party Claim without the prior
     written consent of the Indemnifying Party (not to be withheld
     unreasonably), and (C) the Indemnifying Party will not consent to the entry
     of any judgment or enter into any settlement with respect to the Third
     Party Claim without the prior written consent of the Indemnified Party (not
     to be withheld unreasonably).

          (iv)  In the event any of the conditions in (S)6(d)(ii) above is or
     becomes unsatisfied, however, (A) the Indemnified Party may defend against,
     and consent to the entry of any judgment or enter into any settlement with
     respect to, the Third Party Claim in any manner it reasonably may deem
     appropriate (and the Indemnified Party need not consult with, or obtain any
     consent from, any Indemnifying Party in connection therewith), (B) the
     Indemnifying Parties will reimburse the Indemnified Party promptly and
     periodically for the costs of defending against the Third Party Claim
     (including reasonable attorneys' fees and expenses), and (C) the
     Indemnifying Parties will remain responsible for any Adverse Consequences
     the Indemnified Party may suffer resulting from, arising out of, relating
     to, in the nature of, or caused by the Third Party Claim to the fullest
     extent provided in this (S)6.

     (e) Determination of Adverse Consequences. The Parties shall take into
         --------------------------------------                            
account the time cost of money (using the Applicable Rate as the discount rate)
in determining Adverse 

                                       24
<PAGE>
 
Consequences for purposes of this (S)6. All indemnification payments under this
(S)6 shall be deemed adjustments to the Purchase Price. In determining the
amount of any loss, liability or expense for which any party is entitled to
indemnification under this Agreement, the gross amount thereof will be reduced
by any correlative insurance proceeds realized or to be realized by such party
(or, in the case of the Buyer by the Company) and such correlative insurance
benefit shall be net of any insurance premium which becomes due as a result of
such claim.

     (f)  Other Indemnification Provisions. The foregoing indemnification
          ---------------------------------                              
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of representation,
warranty, or covenant. Each of the Sellers hereby agrees that he or it will not
make any claim for indemnification against the Company  by reason of the fact
that he or it was a director, officer, employee, or agent of any such entity or
was serving at the request of any such entity as a partner, trustee, director,
officer, employee, or agent of another entity (whether such claim is for
judgments, damages, penalties, fines, costs, amounts paid in settlement, losses,
expenses, or otherwise and whether such claim is pursuant to any statute,
charter document, bylaw, agreement, or otherwise) with respect to any action,
suit, proceeding, complaint, claim, or demand brought by the Buyer against such
Seller (whether such action, suit, proceeding, complaint, claim, or demand is
pursuant to this Agreement, applicable law, or otherwise).

     (g)  Limitation of Liability.  Notwithstanding any other provision of this
          -----------------------                                              
Agreement, the aggregate liability of the Sellers for all such breaches and
indemnification shall not exceed the Purchase Price.

     7. Tax Matters. The following provisions shall govern the allocation of
        ------------                                                        
responsibility as between Buyer and Sellers for certain tax matters following
the Closing Date:

     (a)  Section 338(h)(10) Election. Each of Sellers agree, if so directed by
          ----------------------------                                         
the Buyer, to join with Buyer in making an election under Section 338(h)(10) of
the Code (and any corresponding elections under state, local, or foreign tax
law) (collectively, a "Section 338(h)(10) Election") with respect to the
purchase and sale of the stock of the Company hereunder. Buyer will pay any Tax,
including any liability of Company for Tax resulting from the application to it
of Treasury Regulation (S) 1.338(h)(10)-1(f)(5), attributable to the making of
the Section 338(h)(10) Election and will indemnify the Sellers against any
Adverse Consequences arising out of any failure to pay such Tax. Buyer will also
pay any state, local, or foreign Tax (and indemnify the Sellers against any
Adverse Consequences arising out of any failure to pay such Tax) attributable to
an election under state, local or foreign law similar to the election available
under Section 338(g) of the Code (or which results from the making of an
election under Section 338(g) of the Code) with respect to the purchase and sale
of the stock of the Company hereunder.

                                       25
<PAGE>
 
     (b) Tax Periods Ending on or Before the Closing Date. Sellers shall, at
         -------------------------------------------------                  
their sole cost and expense, prepare or cause to be prepared and file or cause
to be filed all Tax Returns for the Company  for all periods ending on or prior
to the Closing Date which are filed after the Closing Date. Sellers shall permit
Company to review and comment on each such Tax Return described in the preceding
sentence prior to filing. Sellers shall reimburse Buyer for Taxes of the Company
with respect to such periods within fifteen (15) days after payment by Buyer or
the Company  of such Taxes to the extent such Taxes are not reflected in the
reserve for Tax Liability (rather than any reserve for deferred Taxes
established to reflect timing differences between book and Tax income) shown on
the face of the Closing Balance Sheet.

     (c) Tax Periods Beginning Before and Ending After the Closing Date. Buyer
         ---------------------------------------------------------------      
shall prepare or cause to be prepared and file or cause to be filed any Tax
Returns of the Company  for Tax periods which begin before the Closing Date and
end after the Closing Date. Sellers shall pay to Buyer within fifteen (15) days
after the date on which Taxes are paid with respect to such periods an amount
equal to the portion of such Taxes which relates to the portion of such Taxable
period ending on the Closing Date to the extent such Taxes are not reflected in
the reserve for Tax Liability (rather than any reserve for deferred Taxes
established to reflect timing differences between book and Tax income) shown on
the face of the Closing Balance Sheet. For purposes of this Section, in the case
of any Taxes that are imposed on a periodic basis and are payable for a Taxable
period that includes (but does not end on) the Closing Date, the portion of such
Tax which relates to the portion of such Taxable period ending on the Closing
Date shall (x) in the case of any Taxes other than Taxes based upon or related
to income or receipts, be deemed to be the amount of such Tax for the entire
Taxable period multiplied by a fraction the numerator of which is the number of
days in the Taxable period ending on the Closing Date and the denominator of
which is the number of days in the entire Taxable period, and (y) in the case of
any Tax based upon or related to income or receipts be deemed equal to the
amount which would be payable if the relevant Taxable period ended on the
Closing Date. Any credits relating to a Taxable period that begins before and
ends after the Closing Date shall be taken into account as though the relevant
Taxable period ended on the Closing Date. All determinations necessary to give
effect to the foregoing allocations shall be made in a manner consistent with
prior practice of the Company .

     (d) Cooperation on Tax Matters.
         ---------------------------

          (i)   Buyer, the Company  and Sellers shall cooperate fully, as and to
     the extent reasonably requested by the other party, in connection with the
     filing of Tax Returns pursuant to this Section and any audit, litigation or
     other proceeding with respect to Taxes. Such cooperation shall include the
     retention and (upon the other party's request) the provision of records and
     information which are reasonably relevant to any such audit, litigation or
     other proceeding and making employees available on a mutually convenient
     basis to provide additional information and explanation of any material
     provided hereunder. The Company and Sellers agree (A) to retain all books
     and 

                                       26
<PAGE>
 
     records with respect to Tax matters pertinent to the Company relating to
     any taxable period beginning before the Closing Date until the expiration
     of the statute of limitations (and, to the extent notified by Buyer or
     Sellers, any extensions thereof) of the respective taxable periods, and to
     abide by all record retention agreements entered into with any taxing
     authority, and (B) to give the other party reasonable written notice prior
     to transferring, destroying or discarding any such books and records and,
     if the other party so requests, the Company or Sellers, as the case may be,
     shall allow the other party to take possession of such books and records.

          (ii)  Buyer and Sellers further agree, upon request, to use their best
     efforts to obtain any certificate or other document from any governmental
     authority or any other Person as may be necessary to mitigate, reduce or
     eliminate any Tax that could be imposed (including, but not limited to,
     with respect to the transactions contemplated hereby).

          (iii) Buyer and Sellers further agree, upon request, to provide the
     other party with all information that either party may be required to
     report pursuant to Section 6043 of the Code and all Treasury Department
     Regulations promulgated thereunder.

     (e) Tax Sharing Agreements. All tax sharing agreements or similar
         -----------------------                                      
agreements with respect to or involving the Company  shall be terminated as of
the Closing Date and, after the Closing Date, the Company  shall not be bound
thereby or have any liability thereunder.

     (f) Certain Taxes. All transfer, documentary, sales, use, stamp,
         --------------                                              
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement (including any New York
State Gains Tax, New York City Transfer Tax and any similar tax imposed in other
states or subdivisions), shall be paid by Sellers when due, and Sellers will, at
their own expense, file all necessary Tax Returns and other documentation with
respect to all such transfer, documentary, sales, use, stamp, registration and
other Taxes and fees, and, if required by applicable law, Buyer will, and will
cause its affiliates to, join in the execution of any such Tax Returns and other
documentation.

     8. Miscellaneous.
        --------------

     (a) Nature of Certain Obligations.
         ------------------------------

          (i)   The covenants of each of the Sellers in (S)2(a) above concerning
     the sale of his Company Shares to the Buyer and the representations and
     warranties of each of the Sellers in (S)3(a) above concerning the
     transaction are several obligations. This means that the particular Seller
     making the representation, warranty, or covenant will be solely responsible
     to the extent provided in (S)6 above for any Adverse Consequences the Buyer
     may suffer as a result of any breach thereof.

                                       27
<PAGE>
 
          (ii)  The remainder of the representations, warranties, and covenants
     in this Agreement are joint and several obligations. This means that each
     Seller will be responsible to the extent provided in (S)6 above for the
     entirety of any Adverse Consequences the Buyer may suffer as a result of
     any breach thereof.

     (b) Press Releases and Public Announcements. No Party shall issue any press
         ----------------------------------------                               
release or make any public announcement relating to the subject matter of this
Agreement prior to the Closing without the prior written approval of the Buyer
and the Requisite Sellers; provided, however, that any Party may make any public
                           -----------------                                    
disclosure it believes in good faith is required by applicable law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the disclosing Party will use its reasonable best efforts to advise the
other Parties prior to making the disclosure).

     (c) No Third-Party Beneficiaries. This Agreement shall not confer any
         -----------------------------                                    
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

     (d) Entire Agreement. This Agreement (including the documents referred to
         -----------------                                                    
herein) constitutes the entire agreement among the Parties and supersedes any
prior understandings, agreements, negotiations or representations by or among
the Parties or their representatives, whether written or oral, to the extent
they related in any way to the subject matter hereof.

     (e) Succession and Assignment. This Agreement shall be binding upon and
         --------------------------                                         
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of his
or its rights, interests, or obligations hereunder without the prior written
approval of the Buyer and the Requisite Sellers; provided, however, that the
                                                 -----------------          
Buyer may (i) assign any or all of its rights and interests hereunder to one or
more of its Affiliates and (ii) designate one or more of its Affiliates to
perform its obligations hereunder (in any or all of which cases the Buyer
nonetheless shall remain responsible for the performance of all of its
obligations hereunder).

     (f) Counterparts. This Agreement may be executed in one or more
         -------------                                              
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

     (g) Headings. The section headings contained in this Agreement are inserted
         ---------                                                              
for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

     (h) Notices. All notices, requests, demands, claims, and other

                         Chairman of the Board            

Any Party may send any notice, request, demand, claim, or other communication
hereunder to the intended recipient at the address set forth above using any
other means (including personal delivery, expedited courier, messenger service,
telecopy, telex, ordinary mail, or electronic mail), but no such notice,
request, demand, claim, or other communication shall be deemed to have been duly
given unless and until it actually is received by the intended recipient. Any
Party may change the address to which notices, requests, demands, claims, and
other communications hereunder are to be delivered by giving the other Parties
notice in the manner herein set forth.

     (i) Governing Law. This Agreement shall be governed by and construed in
         -------------                                                      
accordance with the domestic laws of the State of Texas without giving effect to
any choice or conflict of law provision or rule (whether of the State of Texas
or any other jurisdiction) that would cause the application of the laws of any
other jurisdiction.

     (j) Amendments and Waivers. No amendment of any provision of this Agreement
         -----------------------                                                
shall be valid unless the same shall be in writing and signed by the Buyer and
the Requisite Sellers. No waiver by any Party of any default, misrepresentation,
or breach of warranty or covenant hereunder, whether intentional or not, shall
be deemed to extend to any prior or subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising
by virtue of any prior or subsequent such occurrence.

                                       29
<PAGE>
 
     (k) Severability. Any term or provision of this Agreement that is invalid
         -------------                                                        
or unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

     (l) Expenses. Each of the Parties, the Company,  will bear his or its own
         ---------                                                            
costs and expenses (including legal fees and expenses) incurred in connection
with this Agreement and the transactions contemplated hereby. The Sellers agree
that the Company has not borne or will bear any of the Sellers' costs and
expenses (including any of their legal fees and expenses) in connection with
this Agreement or any of the transactions contemplated hereby.

     (m) Construction. The Parties have participated jointly in the negotiation
         -------------                                                         
and drafting of this Agreement. In the event an ambiguity or question of intent
or interpretation arises, this Agreement shall be construed as if drafted
jointly by the Parties and no presumption or burden of proof shall arise
favoring or disfavoring any Party by virtue of the authorship of any of the
provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty, and covenant contained herein shall have
independent significance. If any Party has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there
exists another representation, warranty, or covenant relating to the same
subject matter (regardless of the relative levels of specificity) which the
Party has not breached shall not detract from or mitigate the fact that the
Party is in breach of the first representation, warranty, or covenant.

     (n) Incorporation of Exhibits, Annexes, and Schedules. The Exhibits,
         --------------------------------------------------              
Annexes, and Schedules identified in this Agreement are incorporated herein by
reference and made a part hereof.

     (o) Specific Performance. Each of the Parties acknowledges and agrees that
         ---------------------                                                 
the other Parties would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Parties shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the
Parties and the matter [(subject to the provisions set forth in (S)10(p)
below)], in addition to any other remedy to which they may be entitled, at law
or in equity.
 
     (p) Submission to Jurisdiction. Each of the Parties submits to the
         ---------------------------                                   
jurisdiction of any state or federal court sitting in Los Angeles County,
California, in any action or proceeding arising out of or relating to this
Agreement and agrees that all claims in respect of the action or 

                                       30
<PAGE>
 
proceeding may be heard and determined in any such court. Each Party also agrees
not to bring any action or proceeding arising out of or relating to this
Agreement in any other court. Each of the Parties waives any defense of
inconvenient forum to the maintenance of any action or proceeding so brought and
waives any bond, surety, or other security that might be required of any other
Party with respect thereto.

                                       31

          Multiemployer Plan) equals or exceeds the present value of all vested
          and nonvested Liabilities thereunder determined in accordance with

          investigation.

                 (C)  The Company has not incurred, and none of the Seller and
          the directors and officers (and employees with responsibility for
          employee benefits matters) of the Company has any reason to expect
          that the Company will incur, any Liability to the PBGC (other than
          PBGC premium payments) or otherwise under Title IV of ERISA (including
          any withdrawal Liability) or under the Code with respect to any such
          Employee Benefit Plan which is an Employee Pension Benefit Plan.

          (iii)  The Company does not contribute to, never has contributed to,

5.  POST-CLOSING COVENANTS. The Parties agree as follows with respect to the
    -----------------------                                                 
period following the Closing.

    (a)  GENERAL. In case at any time after the Effective Date any further
         -------
action is necessary or desirable to carry out the purposes of this Agreement,
each of the Parties will take such further action (including the execution and
delivery of such further instruments and documents) as any other Party
reasonably may request, all at the sole cost and expense of the requesting Party
(unless the requesting Party is entitled to indemnification therefor under
Section 6 below). The Sellers acknowledge and agree that from and after the
Effective Date the Buyer will be entitled to possession of all documents, books,
records (including Tax records), agreements, and financial data of any sort
relating to the Company.

actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, claim, or demand in connection with
(i) any transaction contemplated under this Agreement or (ii) any fact,
situation, circumstance, status, condition, activity, practice, plan,

         ------------------

6.   REMEDIES FOR BREACHES OF THIS AGREEMENT.

     (a)  SURVIVAL OF REPRESENTATIONS AND WARRANTIES.

All of the representations and warranties of the Parties contained in this
Agreement shall survive the Closing hereunder without regard to any

time of Closing) and continue in full force and effect forever thereafter
(subject to any applicable statutes of limitations).

     (b)  INDEMNIFICATION PROVISIONS FOR BENEFIT OF THE BUYER.

          (i)    Subject to the limitations set forth in Section 6(e) below, in
     the event the Sellers breach (or in the event any third party alleges facts

     representations, warranties, and covenants contained herein (other than the
     covenants in Section 2(a) above and the representations and warranties in
     Section 3(a) above), and, if there is an applicable survival period
     pursuant to Section 6(a) above, provided that the Buyer makes a written
     claim for indemnification against the Sellers pursuant to Section 8(h)
     below within such survival period, then the Sellers agree to indemnify the
     Buyer from and against the entirety of any Adverse Consequences the Buyer
     may suffer through and after the date of the claim for indemnification
     (including any Adverse Consequences the Buyer may suffer after the end of
     any applicable survival period) resulting from, arising out of, relating
     to, in the nature of, or caused by the breach (or the alleged breach).

          (ii)   Subject to the limitations set forth in Section 6(e) below, in
     the event the Sellers breach (or in the event any third party alleges facts
     that, if true, would mean any of the Sellers has breached) any of his or
     its covenants in Section 2(a) above or any of his or its representations
     and warranties in Section 3(a) above, and, if there is an applicable
     survival period pursuant to Section 6(a) above, provided that the Buyer
     makes a written claim for indemnification against the Sellers pursuant to
     Section 8(h) below within such survival period, then the Sellers agree to
     indemnify the Buyer from and against the entirety of any Adverse
     Consequences the Buyer may suffer through and after the date of the claim

     to, in the nature of, or caused by the breach (or the alleged breach).

          (iii) Subject to the limitations set forth in Section 6(e) below, the
     Sellers agree to indemnify the Buyer from and against the entirety of any
     Adverse Consequences the Buyer may suffer resulting from, arising out of,

     before and ending after the Closing Date to the extent allocable
     (determined in a manner consistent with Section 8(c)) to the portion of
     such period beginning before and ending on the Closing Date), to the extent
     such Taxes are not reflected in the reserve for Tax Liability (rather than
     any reserve for deferred Taxes established to reflect timing differences
     between book and Tax income) shown on the face of the Most Recent Balance
     Sheet (rather than in any notes thereto)[, as such reserve is adjusted for
     the passage of time through the Closing Date in accordance with the past
     custom and practice of the Company in filing their Tax Returns, and (B) for
     the unpaid Taxes of any Person (other than the Company) under Reg. Section

     transferee or successor, by contract, or otherwise.

limitations set forth in Section 6(e) below, in the event the Buyer breaches (or
in the event any third party alleges facts that, if true, would mean the Buyer
has breached) any of its representations, warranties, and covenants contained
herein, and, if there is an applicable survival period pursuant to Section 6(a)
above, provided that the Sellers make a written claim for indemnification
against the Buyer pursuant to Section 8(h) below within such survival period,
then the Buyer agrees to indemnify each of the Seller from and against the
entirety of any Adverse Consequences the Sellers may suffer through and after
the date of the claim for indemnification (including any Adverse Consequences
the Sellers may suffer after the end of any applicable survival period)
resulting from, arising out of, relating to, in the nature of, or caused by the
breach (or the alleged breach).

     (d)  MATTERS INVOLVING THIRD PARTIES.

          (i)    If any third party shall notify any Party (the "Indemnified 
                                                                ------------
     Party") with respect to any matter (a "Third Party Claim") which may give 
     ------                                -------------------          
     rise to a claim for indemnification against any other Party (the 
                                                                 
     "Indemnifying Party") under this Section 6, then the Indemnified Party
     --------------------
     shall promptly notify each Indemnifying Party thereof in writing; provided,
                                                                       --------
     however, that no delay on the part of the Indemnified Party in notifying
     any Indemnifying Party shall relieve the Indemnifying Party from any
     obligation hereunder unless (and then solely to the extent) the
     Indemnifying Party thereby is prejudiced.

          (ii)   Any Indemnifying Party will have the right to defend the
     Indemnified Party against the Third Party Claim with counsel of its choice
     reasonably satisfactory to the Indemnified Party so long as (A) the
     Indemnifying Party notifies the Indemnified

<PAGE>
 
     Party in writing within 30 days after the Indemnified Party has given
     notice of the Third Party Claim that the Indemnifying Party will indemnify
     the Indemnified Party from and against the entirety of any Adverse
     Consequences the Indemnified Party may suffer resulting from, arising out
     of, relating to, in the nature of, or caused by the Third Party Claim, (B)
     the Indemnifying Party provides the Indemnified Party with evidence
     reasonably acceptable to the Indemnified Party that the Indemnifying Party
     will have the financial resources to defend against the Third Party Claim
     and fulfill its indemnification obligations hereunder, (C) the Third Party
     Claim involves only money damages and does not seek an injunction or other
     equitable relief, (D) settlement of, or an adverse judgment with respect
     to, the Third Party Claim is not, in the good faith judgment of the
     Indemnified Party, likely to establish a precedential custom or practice
     materially adverse to the continuing business interests of the Indemnified
     Party, and (E) the Indemnifying Party conducts the defense of the Third
     Party Claim actively and diligently.

          (iii)  So long as the Indemnifying Party is conducting the defense of
     the Third Party Claim in accordance with Section 6(d)(ii) above, (A) the
     Indemnified Party may retain separate co-counsel at its sole cost and
     expense and participate in the defense of the Third Party Claim, (B) the
     Indemnified Party will not consent to the entry of any judgment or enter
     into any settlement with respect to the Third Party Claim without the prior
     written consent of the Indemnifying Party (not to be withheld
     unreasonably), and (C) the Indemnifying Party will not consent to the entry
     of any judgment or enter into any settlement with respect to the Third
     Party Claim without the prior written consent of the Indemnified Party (not
     to be withheld unreasonably).

          (iv)   In the event any of the conditions in Section 6(d)(ii) above is
     or becomes unsatisfied, however, (A) the Indemnified Party may defend
     against, and consent to the entry of any judgment or enter into any
     settlement with respect to, the Third Party Claim in any manner it
     reasonably may deem appropriate (and the Indemnified Party need not consult
     with, or obtain any consent from, any Indemnifying Party in connection
     therewith), (B) the Indemnifying Parties will reimburse the Indemnified
     Party promptly and periodically for the costs of defending against the
     Third Party Claim (including reasonable attorneys' fees and expenses), and
     (C) the Indemnifying Parties will remain responsible for any Adverse
     Consequences the Indemnified Party may suffer resulting from, arising out
     of, relating to, in the nature of, or caused by the Third Party Claim to
     the fullest extent provided in this Section 6.

     (e) LIMITATIONS. The provisions of this Section 6 notwithstanding, neither
         -----------          
the Buyer nor the Sellers shall be liable to or required to indemnify the other
under Sections 6(b) or (c) until the aggregate amount otherwise due the party to
be indemnified exceeds an accumulated total of Thirty Thousand Dollars
($30,000.00).

     (f)  DETERMINATION OF ADVERSE CONSEQUENCES. The Parties shall take into
          -------------------------------------
account the time cost of money (using the Applicable Rate as the discount rate)
in determining Adverse

<PAGE>
 
Consequences for purposes of this Section 6. All indemnification payments under
this Section 6 shall be deemed adjustments to the Purchase Price.

     (g)  OTHER INDEMNIFICATION PROVISIONS. The foregoing indemnification
          --------------------------------  
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of representation,
warranty, or covenant. The Sellers hereby agree that they will not make any
claim for indemnification against the Company by reason of the fact that he or
it was a director, officer, employee, or agent of any such entity or was serving
at the request of any such entity as a partner, trustee, director, officer,
employee, or agent of another entity (whether such claim is for judgments,
damages, penalties, fines, costs, amounts paid in settlement, losses, expenses,
or otherwise and whether such claim is pursuant to any statute, charter
document, bylaw, agreement, or otherwise) with respect to any action, suit,
proceeding, complaint, claim, or demand brought by the Buyer against such Seller
(whether such action, suit, proceeding, complaint, claim, or demand is pursuant
to this Agreement, applicable law, or otherwise).

7.   TAX MATTERS.  The following provisions shall govern the allocation of
responsibility as between Buyer and Sellers for certain tax matters following
the Closing Date:

     (a)  TAX PERIODS ENDING ON OR BEFORE THE CLOSING DATE. Buyer shall prepare
          ------------------------------------------------
or cause to be prepared and file or cause to be filed all Tax Returns for the
Company for all periods ending on or prior to the Closing Date which are filed
after the Closing. Buyer shall permit Company to review and comment on each such
Tax Return described in the preceding sentence prior to filing. Sellers shall
reimburse Buyer for Taxes of the Company with respect to such periods within
fifteen (15) days after payment by Buyer or the Company of such Taxes to the
extent such Taxes are not reflected in the reserve for Tax Liability (rather
than any reserve for deferred Taxes established to reflect timing differences
between book and Tax income) shown on the face of the Most Recent Balance Sheet
or incurred in the ordinary course of business since that date.

     (b)  TAX PERIODS BEGINNING BEFORE AND ENDING AFTER THE CLOSING DATE. Buyer
          --------------------------------------------------------------
shall prepare or cause to be prepared and file or cause to be filed any Tax
Returns of the Company for Tax periods which begin before the Closing Date and
end after the Closing Date. Seller shall pay to Buyer within fifteen (15) days
after the date on which Taxes are paid with respect to such periods an amount
equal to the portion of such Taxes which relates to the portion of such Taxable
period ending on the Closing Date to the extent such Taxes are not reflected in
the reserve for Tax Liability (rather than any reserve for deferred Taxes
established to reflect timing differences between book and Tax income) shown on
the face of the Closing Balance Sheet. For purposes of this Section, in the case
of any Taxes that are imposed on a periodic basis and are payable for a Taxable
period that includes (but does not end on) the Closing Date, the portion of such
Tax which relates to the portion of such Taxable period ending on the Closing
Date shall (i) in the case of any Taxes other than Taxes based upon or related
to income or receipts, be deemed to be the amount of such Tax for the entire
Taxable period multiplied by a fraction the numerator

<PAGE>
 
of which is the number of days in the Taxable period ending on the Closing Date
and the denominator of which is the number of days in the entire Taxable period,
and (ii) in the case of any Tax based upon or related to income or receipts be
deemed equal to the amount which would be payable if the relevant Taxable period
ended on the Closing Date. Any credits relating to a Taxable period that begins
before and ends after the Closing Date shall be taken into account as though the
relevant Taxable period ended on the Closing Date. All determinations necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of the Company .

     (c)  COOPERATION ON TAX MATTERS.

          (i)    Buyer, the Company and Sellers shall cooperate fully, as and to
     the extent reasonably requested by the other party, in connection with the
     filing of Tax Returns pursuant to this Section and any audit, litigation or
     other proceeding with respect to Taxes. Such cooperation shall include the
     retention and (upon the other party's request) the provision of records and
     information which are reasonably relevant to any such audit, litigation or
     other proceeding and making employees available on a mutually convenient
     basis to provide additional information and explanation of any material
     provided hereunder. The Company and Sellers agree (A) to retain all books
     and records with respect to Tax matters pertinent to the Company relating
     to any taxable period beginning before the Closing Date until the
     expiration of the statute of limitations (and, to the extent notified by
     Buyer or Sellers, any extensions thereof) of the respective taxable
     periods, and to abide by all record retention agreements entered into with
     any taxing authority, and (B) to give the other party reasonable written
     notice prior to transferring, destroying or discarding any such books and
     records and, if the other party so requests, the Company or Sellers, as the
     case may be, shall allow the other party to take possession of such books
     and records.

          (ii)   Buyer and Sellers further agree, upon request, to use their
     best efforts to obtain any certificate or other document from any
     governmental authority or any other Person as may be necessary to mitigate,
     reduce or eliminate any Tax that could be imposed (including, but not
     limited to, with respect to the transactions contemplated hereby).

          (iii)  Buyer and Sellers further agree, upon request, to provide the
     other party with all information that either party may be required to
     report pursuant to Section 6043 of the Code and all Treasury Department
     Regulations promulgated thereunder.

     (d)  TAX SHARING AGREEMENTS. All tax sharing agreements or similar
          ----------------------
agreements with respect to or involving the Company shall be terminated as of
the Closing Date and, after the Closing Date, the Company shall not be bound
thereby or have any liability thereunder.

<PAGE>
 
     (e)  CERTAIN TAXES. All transfer, documentary, sales, use, stamp,
          ------------- 
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement (including any New York
State Gains Tax, New York City Transfer Tax and any similar tax imposed in other
states or subdivisions), shall be paid by Sellers when due, and Seller will, at
their own expense, file all necessary Tax Returns and other documentation with
respect to all such transfer, documentary, sales, use, stamp, registration and
other Taxes and fees, and, if required by applicable law, Buyer will, and will
cause its affiliates to, join in the execution of any such Tax Returns and other
documentation.

8.   MISCELLANEOUS.

     (a)  ARBITRATION. The Parties agree that except with respect to any action
          -----------
for an injunction pursuant to the provisions of the Agreement Not To Compete
(Exhibit D hereto), all disputes among the Parties after the Closing arising out
of or relating to this Agreement, including without limitation the indemnities
provided above or the breach thereof, shall be submitted to the American
Arbitration Association ("AAA") for arbitration before a single arbitrator for
final and binding arbitration in accordance with the rules of AAA then in effect
or such other procedures as the Parties may agree to as the sole and exclusive
remedy for resolving such disputes. The Parties agree that the decision of the
arbitrator shall be final and binding between the Parties thereto, and shall be
enforceable by any court having jurisdiction over the party against whom
enforcement is sought. The Parties agree that any such arbitration shall take
place in Dallas, Texas. The fees and expenses of such arbitration (including
reasonable attorneys' fees) or any action to enforce an arbitration award shall
be paid by the party that does not prevail in such arbitration.

     (b)  WAIVER OF JURY TRIAL.  THE PARTIES EACH ACKNOWLEDGE AND AGREE THAT BY
          --------------------                                                 
SELECTING ARBITRATION AS THE SOLE AND EXCLUSIVE REMEDY FOR RESOLVING ALL
DISPUTES AMONG THEM (OTHER THAN THOSE SET FORTH IN SECTION 5(d)), THEY ARE
WAIVING THEIR RIGHT TO A JURY TRIAL TO WHICH THEY MAY OTHERWISE BE ENTITLED.

     (c)  NATURE OF CERTAIN OBLIGATIONS. The representations, warranties, and
          ------------------------------                                     
covenants in this Agreement are a material inducement to Buyer in entering into
this Agreement. Thus, Sellers ill be responsible to the extent provided in
Section 6 above for the entirety of any Adverse Consequences the Buyer may
suffer as a result of any breach thereof.

     (d)  PRESS RELEASES AND PUBLIC ANNOUNCEMENTS. No Party shall issue any
          ---------------------------------------
press release or make any public announcement relating to the subject matter of
this Agreement prior to the Closing without the prior written approval of the
Buyer and Higginbotham; provided, however, that any Party may make any public
                        --------  ------- 
disclosure it believes in good faith is required by applicable law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the disclosing Party will use its reasonable best efforts to advise the
other Parties prior to making the disclosure).

     (e)  NO THIRD-PARTY BENEFICIARIES. This Agreement shall not confer any
          ----------------------------     
rights or remedies upon any Person other than the Parties and their respective
successors and permitted assigns.

     (f)  ENTIRE AGREEMENT. This Agreement (including the documents referred to
          -----------------                                                    
herein) constitutes the entire agreement among the Parties and supersedes any
prior understandings, agreements, negotiations or representations by or among
the Parties or their representatives, whether written or oral, to the extent
they related in any way to the subject matter hereof.

     (g)  SUCCESSION AND ASSIGNMENT. This Agreement shall be binding upon and
          -------------------------   
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of his
or its rights, interests, or obligations hereunder without the prior written
approval of the Buyer and the Seller; provided, however, that the Buyer may (i)
                                      --------  -------
assign any or all of its rights and interests hereunder to one or more of its
Affiliates and (ii) designate one or more of its Affiliates to perform its
obligations hereunder (in any or all of which cases the Buyer nonetheless shall
remain responsible for the performance of all of its obligations hereunder).

     (h)  COUNTERPARTS. This Agreement may be executed in one or more
          ------------
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

     (i)  HEADINGS. The section headings contained in this Agreement are

     (l)  AMENDMENTS AND WAIVERS. No amendment of any provision of this
          ----------------------
Agreement shall be valid unless the same shall be in writing and signed by the
Buyer and the Sellers. No waiver by any Party of any default, misrepresentation,

     (m)  SEVERABILITY. Any term or provision of this Agreement that is invalid

   Mr. Jeff J. Elston
   Aurora Visual Systems
   1530 First Avenue S.
   Seattle, WA 98134

   Dear Jeff:

   This letter will confirm our Agreement in Principle (the "Agreement in
   Principle") with respect to the acquisition (the "transaction") by Electronic
   Integrated Solutions, Inc. ("Buyer"), a California corporation, of the assets
   subject to the liabilities of Aurora Visual Systems ("Aurora") on the
   following basis:

   1.    It is contemplated that the transaction will be structured as a
         purchase of the net assets and the business of Aurora.

   2.    (A)  The aggregate purchase price (the "purchase price") for the entire
         interest in Aurora will be $1,500,000, as described below, payable
         beginning upon the closing date (the "Closing Date") of the
         transaction.

         (B)  The purchase price will be payable as follows:

              (1) in cash (the "Cash Payment"), an amount equal to $1,000,000;

              (2) in common stock of Electronic Integrated Solutions an amount
                  of shares equivalent to $500,000 when Buyer has its public
                  offering. If no pubic offering for the shares of Buyer occurs
                  within 15 months from the closing, then the shares (or any
                  portion of them) may, at the sole option of the selling
                  shareholders of Aurora, be converted into a demand note
                  payable over six months from that date with interest at the
                  Wells Fargo Bank (or successor) prime rate, payable monthly
                  including principal and interest. All shares issued shall bear
                  legend restrictions upon their sale as is customary for such
                  shares. In addition, if no public offering has occurred within
                  7 months of the closing, the $500,000 will increase in value
                  applying the above prime rate for the period between the 7th
                  month and the 15th month.

   3.    You have previously delivered to Buyer certain financial statements and
         projections of future operating results.  Buyer is relying on the
         accuracy of the information contained therein in proceeding with the
         transaction.  In addition, you have advised Buyer that Aurora has, and
         at the closing will have, no material liabilities, contingent or
         otherwise, except for liabilities disclosed in the financial
         information submitted or incurred subsequent to the date thereof in the
         ordinary course of business, consistent with past practice.

   4.    The transaction is subject to negotiation and execution of a definitive
         Purchase Agreement and related agreements acceptable in form and
         substance to Buyer and Seller containing, among other things, terms,
         representations, warranties, covenants, agreements and conditions
         customary for transactions of this type; and further due diligence by
         Buyer.

   5.    This offer represents a substantial commitment by Buyer of its time,
         effort and financial resources to the transaction rather than to
         alternative acquisition opportunities available to it. Accordingly, you
         have committed to Buyer that, until the earliest to occur of (i)
         consummation of the transaction, (ii) the termination of our
         negotiations, or (iii) October 31, 1998, you will not, and will cause
         Aurora not to solicit, encourage, or initiate any discussions with, or
         provide any information to any person, entity or group, other than
         Buyer and its employees or agents, concerning any merger,
         consolidation, sale of significant or substantial assets or similar
         transaction involving Aurora or any sale of shares of capital stock
         involving Aurora. You will immediately advise Buyer if you receive any
         acquisition proposal from any other person, entity or group.

   6.    It is understood and agreed that this Agreement in Principle
         constitutes only a statement of our mutual intentions with respect to
         the transaction, does not contain all matters upon which agreement must
         be reached in order for the transaction to be consummated and,
         therefore, does not constitute a binding commitment with respect to the
         transaction itself. A binding commitment with respect to the
         transaction itself can result only from execution of definitive
         agreements, subject to the conditions expressed therein.
         Notwithstanding the two preceding sentences of this paragraph 6, it is
         expressly agreed by the parties hereto that the provisions of paragraph
         6 are fully binding upon the execution of this Agreement in Principle.

   7.    Buyer and Seller will pay their own expenses incurred in connection
         with the preparation, negotiations, execution and delivery of this
         Agreement in Principle, the definitive Purchase Agreement and all
         related agreements and the consummation of this transaction.

   If the foregoing accurately summarizes our understanding, we request that you
   execute the enclosed copy of this letter and return it to the undersigned.

Sincerely,

/s/ DONALD J. ESTERS

Paul Peck
Proline Systems
1233 120th Avenue N.E.
Bellevue, WA 98005

Dear Paul:

This communication will serve as our Letter of Intent with respect to the
acquisition (the "transaction") by Electronic Integrated Solutions, Inc.
("Buyer"), a California corporation, of the entire equity interest in Proline
Industries, Inc. ("Proline") on the following basis:

1.  It is contemplated that the transaction will be structured as a purchase of
    the outstanding capital stock of Proline Industries, Inc.

2.  The aggregate purchase price (the "purchase price") for the entire equity
    interest in Proline will be $6,400,000, with the entire amount payable at
    the closing date (the "Closing Date") of the transaction.

3.  As part of the transaction, the Buyer and Paul Peck will negotiate and enter
    into a one year employment contract, which can be extended by mutual
    agreement.

4.  You have previously delivered to Buyer certain financial statements and
    projections of future operating results. Buyer is relying on the accuracy of
    the historical information contained therein in proceeding with the
    transaction. In addition, you have advised Buyer that Proline has, and at
    the closing will have, no material liabilities, contingent or otherwise,
    except for liabilities disclosed in the financial information submitted or
    incurred subsequent to the date thereof in the ordinary course of business,
    consistent with past practice.

5.  The transaction is subject to negotiation and execution of a definitive
    Purchase Agreement and related agreements acceptable in form and substance
    to Buyer and Seller containing, among other things, terms, representations,
    warranties, covenants, agreements and conditions customary for transactions
    of this type; and further due diligence by Buyer.

6.  This offer represents a substantial commitment by Buyer of its time, effort
    and financial resources to the transaction rather than to alternative
    acquisition opportunities available to it. Accordingly, you have committed
    to Buyer that, until the earliest to occur of (i) consummation of the
    transaction, (ii) the termination of our negotiations, or (iii) October 31,
    1998, you will not, and will cause Proline not to solicit, encourage, or
    initiate any discussions with, or provide any information to any person,
    entity or group, other than Buyer and its employees or agents, concerning
    any merger, consolidation, sale of significant or substantial assets or

7.  It is understood and agreed that this Letter of Intent constitutes only a
    statement of our mutual intentions with respect to the transaction, does not
    contain all matters upon which agreement must be reached in order for the
    transaction to be consummated and, therefore, does not constitute a binding
    commitment with respect to the transaction itself. A binding commitment with
    respect to the transaction itself can result only from execution of
    definitive agreements, subject to the conditions expressed therein.
    Notwithstanding the two preceding sentences of this paragraph 7, it is
    expressly agreed by the parties hereto that the provisions of paragraph 6
    are fully binding upon the execution of this Agreement in Principle.

8.  Buyer and Seller will pay their own expenses incurred in connection with the
    preparation, negotiations, execution and delivery of this Agreement in
    Principle, the definitive Purchase Agreement and all related agreements and
    the consummation of this transaction.

If the foregoing accurately summarizes our understanding, we request that you
execute the enclosed copy of this letter and return it to the undersigned.

Sincerely,

and the absence of such qualification could, individually or in the aggregate,
have a material adverse effect on the condition (financial or otherwise),
business, net worth, results of operations, earnings, properties or prospects,
whether or not arising in the ordinary course of business, of EISI and the
Subsidiary considered as a whole.

                (d)  Power and Authority; Effect of Agreement.  EISI has all

contemplated hereby, each of even date herewith (collectively, the "Ancillary
Documents"), and to consummate the transactions contemplated hereby and
thereby. This Agreement has been duly and validly executed and delivered by
EISI and constitutes the valid and binding obligation of EISI, and the
Ancillary Documents, assuming the due execution and delivery hereof by each
Purchaser, upon execution and delivery by EISI, will constitute valid and
binding obligations of EISI, in each case enforceable against EISI in

be limited by (A) bankruptcy, insolvency, reorganization, moratorium (whether
general or specific) or similar laws now or hereafter in effect relating to

          (e)  Such Purchaser is able to bear the economic risk of its
investment in the Shares pursuant to this Agreement and such Purchaser has given
consideration as to whether it can afford to hold its Shares for an indefinite

Shares and that the Shares have not been registered under the Securities Act of

          THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and
for other good and valuable consideration, SAND HILL CAPITAL LLC ("Holder") is
entitled to purchase the number of fully paid and nonassessable shares of Common

(the "Warrant Price") all as set forth above and as adjusted pursuant to Article
2 of this Warrant, subject to the provisions and upon the terms and conditions
set forth in this Warrant.

ARTICLE 1.  EXERCISE.
            -------- 

            1.1.  Method of Exercise.  Holder may exercise this Warrant by
                  ------------------                                      
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company.  Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

            1.2.  Conversion Right.  In lieu of exercising this Warrant as
                  ----------------                                        
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share.  The fair market value of the Shares
shall be determined pursuant to Section 1.4.

            1.3.  No Rights of Shareholders.  This Warrant does not entitle 
                  -------------------------                              
Holder to any voting rights as a shareholder of the Company prior to the
exercise hereof.

            1.4.  Fair Market Value.  If the Shares are traded in a public 
                  -----------------                                  
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day 
<PAGE>
 
immediately before Holder delivers its Notice of Exercise to the Company. If
the Shares are not traded in a public market, the Board of Directors of the
Company shall determine fair market value in its reasonable good faith
judgment. The Directors of the Company shall determine fair market value in
its reasonable good faith judgment. The foregoing notwithstanding, if Holder
advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a
reputable investment banking or public accounting firm to undertake such
valuation. If the valuation of such investment banking firm shall be paid by
the Company. In all other circumstances, such fees and expenses shall be paid
by Holder.

          1.5.  Delivery of Certificate and New Warrant.  Promptly after Holder
                ---------------------------------------                        
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

          1.6.  Replacement of Warrants.  On receipt of evidence reasonably
                -----------------------                                    
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

          1.7.  Repurchase on Sale, Merger, or Consolidation of the Company.
                ----------------------------------------------------------- 

                1.7.1.  "Acquisition".  For the purpose of this Warrant, 
                        -------------                               
"Acquisition" means any sale, license, or other disposition of all or
substantially all of its assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

                1.7.2.  Assumption of Warrant.  Upon the closing of any 
                        ---------------------                         
Acquisition the successor entity shall assume the obligations of this Warrant,
and this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition and subsequent closing. The Warrant Price
shall be adjusted accordingly.

                1.7.3.  Purchase Right.  Notwithstanding the foregoing, at the
                        --------------                                        
election of Holder, the Company shall purchase the unexercised portion of this
Warrant for cash upon the closing of any Acquisition for an amount equal to (a)
the fair market value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES.
            ------------------------- 

            2.1.  Stock Dividends, Splits, Etc.  If the Company declares or 
                  -----------------------------                          
pays a dividend on its common stock payable in common stock, or other
securities, subdivides the outstanding common stock into a greater amount of
common stock, then upon exercise of this Warrant, for each Share acquired,
Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the
Shares of record as of the date the dividend or subdivision occurred.

            2.2.  Reclassification, Exchange or Substitution.  Upon any
                  ------------------------------------------           
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.  The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property.  The new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant.  The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

            2.3.  Adjustments for Combinations, Etc.  If the outstanding Shares
                  ----------------------------------                           
are combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased.

            2.4.  Weighted Average Adjustment.  If the Company issues additional
                  ---------------------------                                   
common shares (including shares of common stock ultimately issuable upon
conversion of a security convertible into common stock) after the date of the
Warrant and the consideration per additional common share is less than the
Warrant Price in effect immediately before such issue, the Warrant Price shall
be reduced, concurrently with such Issue, to a price determined by multiplying
the Warrant Price by a fraction:

                  (a)  the numerator of which is the amount of common stock
outstanding immediately before such Issue plus the amount of common stock that
the aggregate consideration received by the Company for the additional common
shares would purchase at the Warrant Price in effect immediately before such
Issue, and

                  (b)  the denominator of which is the amount of common stock
outstanding immediately before such issue plus the number of such additional
common shares.

Upon each adjustment of the Warrant Price, the number of Shares issuable upon
exercise of the Warrant shall be increased to equal the quotient obtained by
dividing (a) the product resulting from multiplying (i) the number of Shares
issuable upon exercise of the Warrant and (ii) the Warrant Price, in each case
as in effect immediately before such adjustment, by (b) the adjusted Warrant
Price.

            2.5.  No Impairment.  The Company shall not, by amendment of its
                  -------------                                             
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such actions as may be necessary or appropriate
to protect Holder's rights under this Article against impairment.  If the
Company takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares issuable upon
exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

            2.6.  Fractional Shares. No fractional Shares shall be issuable upon
                  -----------------
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder amount computed by
multiplying the fractional interest by the fair market value of a full Share.

            2.7.  Certificate as to Adjustments.  Upon each adjustment of the
                  -----------------------------                              
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial
Officer setting forth such adjustment and the facts upon which such adjustment
is based.  The Company shall, upon written request, furnish Holder a certificate
setting forth the Warrant Price in effect upon the date thereof and the series
of adjustments leading to such Warrant Price.

ARTICLE 3.  REPRESENTATIONS AND COVENANTS OF THE COMPANY.
            -------------------------------------------- 

            3.1.  Representations and Warranties.  The Company hereby represents

times reserve a sufficient number of shares of common stock for issuance upon

above; (2) in the case of the matters referred to in (c) and (d) above at least
20 days prior written notice of the date when the same will take place (and

exchange their common stock for securities or other property deliverable upon
the occurrence of such event); and (3) in the case of the matter referred to in
(e) above, the same notice as is given to the holders of such registration
rights.

            3.3.  Information Rights.  So long as the Holder holds this Warrant
                  ------------------                                           
and/or any of the Shares, the Company shall deliver to the Holder (a) promptly
after mailing, copies of all notices or other written communications to the
shareholders of the Company, (b) within ninety (90) days after the end of each
fiscal year of the Company, the annual financial statements of the Company.

            3.4.  Registration Under Securities Act of 1993, as amended.  The

to the purchasers in the most recently completed issuance of the Company's
equity securities.

                      AGREEMENT WITH SELLER STOCKHOLDERS

          This Agreement with Seller Stockholders dated June 12, 1998 is by and
among  EISI, INC., a California corporation (the "Buyer"), and MICHAEL STAMMIRE,
                                                 -------                        
RICHARD BART MORAN, and CHRIS H. URSETTA (collectively the "Seller Stockholders"
                                                          ----------------------
and each individually referred to herein as a " Seller Stockholder")  who each
                                              ---------------------           
reside in the State of California and who are the stockholders of DIGITAL
NETWORKS CORPORATION, INC., a California corporation (the "Seller"). The Buyer
                                                          --------            
and the Seller Stockholders are referred to collectively herein as the
                                                                      
"Parties." This Agreement shall be effective on and as of the Closing Date.
- ----------                                                                 

                                    RECITALS

          A. The Buyer and the Seller are entering into an Asset Purchase
Agreement concurrently herewith (the "Asset Purchase Agreement"). Certain terms
                                     --------------------------

Agreement.

the Buyer will purchase the Acquired Assets (and accept responsibility for the
Assumed Liabilities) of the Seller in return for cash and other consideration.

          C. The Buyer and the Seller make certain representations, warranties,
and covenants in the Asset Purchase Agreement which will survive the Closing for
purposes of potential indemnification. The Seller Stockholders, however, intend
to cause the Seller to liquidate and dissolve immediately after the Closing. The
Buyer and the Seller Stockholders therefore wish to provide for post-Closing
indemnification against breaches of these representations, warranties, and
covenants and to make certain other covenants among themselves.
 
                                   AGREEMENT

              -----------------

contracts and 

                                       2
<PAGE>

Section 2(h)(i)-(ii) in the Asset Purchase Agreement.

          (c) Investment.  The Seller Stockholder shall not acquire any of the

Buyer Notes or the Convertible Notes (collectively, the "Notes") from the Seller
unless such Seller Stockholder provides a written acknowledgement to the Buyer
that the Seller Stockholder (i) understands the Notes have not been, and will
not be, registered under the Securities Act, or under any state securities laws,
and are being offered and sold in reliance upon federal and state exemptions for
transactions not involving any public offering, (ii) is acquiring the Notes
solely for his own account for investment purposes, and not with a view to the
distribution thereof, (iii) is a sophisticated investor with knowledge and
experience in business and financial matters, (iv) has received certain
information concerning the Buyer and has had the opportunity to obtain

consists of 200,000 shares of "Seller Stock," of which only 60,000 shares are
issued and outstanding and no Seller Stock is held in treasury. Each Seller
Stockholder holds of record 20,000 shares of Seller Stock.

          (e) Seller Representations. All of the representations and warranties
              ----------------------                                           
made by the Seller to the Buyer in the Asset Purchase Agreement are correct and
complete as of the Effective Date.

          3.  Post-Closing Covenants. The Parties agree as follows with respect
              -----------------------                                          
to the period following the Closing.

          (a) General. In case at any time after the Closing any further action
              --------                                                         
is necessary or desirable to carry out the purposes of the Asset Purchase
Agreement, each of the Parties will take such further action (including the
execution and delivery of such further instruments and documents) as any other
Party reasonably may request, all the sole cost and expense of the requesting
Party (unless the requesting Party is entitled to indemnification therefor under
Section 4 below). The Seller Stockholders acknowledge and agree that from and
after the Closing the Buyer will be entitled to possession of all documents,
books, records (including Tax records), agreements, and financial data of any
sort relating to the Seller.

          (b) Litigation Support. In the event and for so long as any Party
              -------------------                                          
actively is contesting or defending against any action, suit, proceeding,
hearing, investigation, charge, complaint, 

                                       3
<PAGE>
 
claim, or demand in connection with (i) any transaction contemplated under the
Asset Purchase Agreement or (ii) any fact, situation, circumstance, status,
condition, activity, practice, plan, occurrence, event, incident, action,
failure to act, or transaction on or prior to the Closing Date involving the
Seller, each of the other Parties will cooperate with the contesting or
defending Party and his counsel in the contest or defense, make available his
personnel, and provide such testimony and access to his books and records as
shall be necessary in connection with the contest or defense, all at the sole
cost and expense of the contesting or defending Party (unless the contesting or
defending Party is entitled to indemnification therefor under Section 4 below).

          (c) Transition. None of the Seller Stockholders will take any action
              -----------                                                     
that is designed or intended to have the effect of discouraging any lessor,
licensor, customer, supplier, or other business associate of the Seller from
maintaining the same business relationships with the Buyer after the Closing as
it maintained with the Seller prior to the Closing. Each of the Seller
Stockholders will refer all customer inquiries relating to the businesses of the
Seller to the Buyer from and after the Closing.

          (d) Confidentiality. Each of the Seller Stockholders will treat and
              ----------------                                               
hold as such all of the Confidential Information, refrain from using any of the
Confidential Information except in connection with this Agreement, and deliver
promptly to the Buyer or destroy, at the request and option of the Buyer, all
tangible embodiments (and all copies) of the Confidential Information which are
in his possession. In the event that any of the Seller Stockholders is requested
or required (by oral question or request for information or documents in any
legal proceeding, interrogatory, subpoena, civil investigative demand, or
similar process) to disclose any Confidential Information, that Seller
Stockholder will notify the Buyer promptly of the request or requirement so that
the Buyer may seek an appropriate protective order or waive compliance with the
provisions of this Section 3(d). If, in the absence of a protective order or the
receipt of a waiver hereunder, any of the Seller Stockholders is, on the advice
of counsel, compelled to disclose any Confidential Information to any tribunal
or else stand liable for contempt, that Seller Stockholder may disclose the
Confidential Information to the tribunal; provided, however, that the disclosing
                                          -----------------                     
Seller Stockholder shall use his best efforts to obtain, at the reasonable
request of the Buyer, an order or other assurance that confidential treatment
will be accorded to such portion of the Confidential Information required to be
disclosed as the Buyer shall designate.

          (e) Covenant Not to Compete. Seller Stockholders each acknowledge and
              ------------------------                                         
agree that they have technical expertise associated with the business of the
Seller and are well known in the presentation/communications industry.  In
addition, the Seller Stockholders have valuable business contacts with clients
and potential clients of the Seller and with professionals in the
presentation/communication industry.  The Seller's reputation and good will are
an integral part of business success throughout the areas where it conducts its
business.  If Seller 

                                       4
<PAGE>
 
Stockholders deprive Buyer of the Seller's goodwill or in any manner use their
reputation and goodwill in competition with the Seller, Buyer will be deprived
of the benefits it has bargained for pursuant to this Agreement. Since Seller
Stockholders have the ability to compete with the Seller in the operation of the
Seller's business, Buyer, therefore, desires that the Seller Stockholders enter
into this covenant not to compete. But for Seller Stockholders' entry into this
covenant not to compete, Buyer would not enter into the Asset Purchase
Agreement. It is, therefore, understood and agreed that by their authorization
of the Seller's entry into the Asset Purchase Agreement, the Seller Stockholders
have transferred to Buyer all of their business goodwill in the Seller as
contemplated by California Business and Professions Code Section 16601. Seller
Stockholders, therefore, agree that for a period of five (5) years from the
Closing (the "Term"), Seller Stockholders shall not, without Buyer's prior
written consent (which may be given or withheld in Buyer's sole and absolute
discretion), directly or indirectly,

          (i)   own, manage, join, operate or control, or participate in the
ownership, management, operation or control of, or be connected as a director,
officer, employee, partner, consultant or otherwise with, or permit their names
to be used by or in connection with, any profit or non-profit business or
organization which produces, designs, conducts research on, provides, sells,
distributes or markets products, goods, equipment or services which, directly or
indirectly compete with the Seller's and/or the Buyer's business, as conducted
by the Seller immediately prior to the Closing and as is proposed to be
conducted by the Buyer after the Closing, in the Counties specified in Exhibit I
attached hereto of the United States, or in any other countries in which the
Seller's and/or the Buyer's business is conducted;

          (ii)  call on or solicit or divert or take away from the Seller and/or
the Buyer (including without limitation by divulging to any competitor or
potential competitor of the Seller and/or the Buyer) any Person, firm or
corporation or other entity who is or which at the Closing was a customer of the
Seller and/or the Buyer or whose identity is known to the Seller Stockholders at
the Closing as one whom the Seller and/or the Buyer intends to solicit;  or

          (iii) hire or offer employment to or seek to hire or offer employment
to any employee of the Seller whose employment is continued by the Seller after
the Closing or any employee of any successor or affiliate of the Seller, unless
Buyer first terminates the employment of such employee or gives its written
consent to such employment or offer of employment.

Seller Stockholders acknowledge that the provisions of this Section 3(e) are
reasonable and necessary to protect legitimate interests of Buyer. Seller
Stockholders further acknowledge that any breach of this Section 3(e) by them
will cause irreparable injury to Buyer, for which the available remedies at law
will not be adequate. Accordingly, in the event of any such breach or threatened
breach of any provisions of this Section 3(e), in addition to any other remedy
provided by law or in equity, the Buyer shall be entitled to appropriate
injunctive relief and/or specific performance, in any court of competent
jurisdiction, restraining the Seller Stockholders from

                                       5
<PAGE>
 
any such actual or threatened breach of this section without posting bond or
other security. Seller Stockholders stipulate to the entry against them of any
temporary, preliminary or permanent injunction and agree not to resist the
Buyer's application for such equitable relief, except on the grounds that the
acts or omissions alleged do not violate any of the provisions of this section.
Seller Stockholders shall, in the event that any injunctive relief or damages
shall be granted to the Buyer, pay all of the Buyer's reasonable costs and
expenses, including attorneys' fees, incurred in obtaining such relief. If the
final judgment of a court of competent jurisdiction declares that any term or
provision of this Section 3(e) is invalid or unenforceable, the Parties agree
that the court making the determination of invalidity or unenforceability shall
have the power to reduce the scope, duration, or area of the term or provision,
to delete specific words or phrases, or to replace any invalid or unenforceable
term or provision with a term or provision that is valid and enforceable and
that comes closest to expressing the intention of the invalid or unenforceable
term or provision, and this Agreement shall be enforceable as so modified after
the expiration of the time within which the judgment may be appealed.

          (f) Personal Guarantees. The Buyer shall, within ninety (90) days
              --------------------                                         
after the date of this Agreement obtain the release of the Seller Stockholders
from any personal guarantees they have given for the indebtedness of the Seller.
The Seller Stockholders have set forth in Schedule 4(f) attached hereto a
complete list of all indebtedness for which they have given a personal guaranty
and have delivered to Buyer correct and complete copies of all documents
evidencing the indebtedness and their personal guarantees.

          (g) Note Legend. Each Note will be imprinted with a legend
              ------------                                          
substantially in the following form:

          THE PAYMENT OF PRINCIPAL AND INTEREST ON THIS NOTE IS SUBJECT TO
          CERTAIN RECOUPMENT AND OFFSET PROVISIONS SET FORTH IN AN AGREEMENT
          WITH SELLER STOCKHOLDERS DATED AS OF JUNE 12, 1998 (THE "AGREEMENT")
          AMONG THE ISSUER OF THIS NOTE AND CERTAIN OTHER PERSONS. THIS NOTE WAS
          ORIGINALLY ISSUED ON ____, 19__, AND HAS NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED. THE TRANSFER OF THIS NOTE IS
          SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN THE AGREEMENT. THE ISSUER
          OF THIS NOTE WILL FURNISH A COPY OF THESE PROVISIONS TO THE HOLDER
          HEREOF WITHOUT CHARGE UPON WRITTEN REQUEST.

Each holder desiring to transfer any Note first must furnish the Buyer with (i)
a written opinion satisfactory to the Buyer in form and substance from counsel
reasonably satisfactory to the Buyer by reason of experience to the effect that
the holder may transfer the Note as desired without registration under the
Securities Act and (ii) a written undertaking executed by the desired transferee
satisfactory to the Buyer in form and substance agreeing to be bound by the
offset and recoupment provisions and the restrictions on transfer contained
herein.

          Liability of the Buyer under any bulk transfer law of any
          jurisdiction, under any common law doctrine of de facto merger or
          successor liability, or otherwise by operation of law);

               (y)   any Liability of any of the Seller for any unpaid Taxes
          with respect to any Tax year or portion thereof ending on or before
          the Closing Date or any Liability of any of the Seller's Subsidiaries
          for the unpaid Taxes of any Person (other than any of the Seller and
          its Subsidiaries) under Reg. Section 1.1502-6 (or any similar
          provision of state, local, or foreign law), as a transferee or
          successor, by contract, or otherwise.

          (iv) The foregoing notwithstanding, the Seller Stockholders shall not
     have any obligation to indemnify the Buyer from and against any Adverse
     Consequences resulting from, arising out of, relating to, in the nature of,
     or caused by the breach (or alleged breach) of any representation or
     warranty of the Seller contained in Section 4(g)-(j) and Section 4(l)-(cc)
     of the Asset Purchase Agreement until the Buyer has suffered Adverse
     Consequences by reason of all such breaches (or alleged breaches) in excess
     of a $20,000 aggregate threshold (at which point the Seller Stockholders
     will be obligated to indemnify the Buyer from and against such further
     Adverse Consequences) and there will be a $1,000,000 aggregate ceiling on
     the obligation of the Seller Stockholders to indemnify the Buyer from and
     against Adverse Consequences.

     (c) Indemnification Provisions for Benefit of the Seller Stockholders. In
         ------------------------------------------------------------------
the event the Buyer breaches (or in the event any third party alleges facts
that, if true, would mean the Buyer has breached) any of its representations,
warranties, and covenants contained in the Asset Purchase Agreement and in this
Agreement, and, if there is an applicable survival period pursuant to Section
4(a) above, provided that any of the Seller Stockholders makes a written claim
for indemnification against the Buyer pursuant to Section 5(h) below within such
survival period, then the Buyer agrees to indemnify each of the Seller
Stockholders from and against any Adverse Consequences the Seller Stockholder
may suffer through and after the date of the claim for indemnification
(including any Adverse Consequences the Seller Stockholder may suffer after the
end of any applicable survival period) resulting from, arising out of, relating
to, in the nature of, or caused by the breach (or the alleged breach).

The Buyer also agrees to indemnify each of the Seller Stockholders from and
against the entirety of any Adverse Consequences the Seller Stockholder may
suffer resulting from, arising out of, relating to, in the nature of, or caused
by any Assumed Liability.

     (d) Matters Involving Third Parties.
         --------------------------------

                                       8

          (i) If any third party shall notify any Party (the "Indemnified
                                                             ------------
     Party") with respect to any matter (a "Third Party Claim") which may give
                                           -------------------                
     rise to a claim for indemnification against any other Party (the
                                                                     
     "Indemnifying Party") under this Section 4, then the Indemnified Party 
     --------------------                                                   
     shall promptly notify each Indemnifying Party thereof in writing; provided,
                                                                       ---------
     however, that no delay on the part of the Indemnified Party in notifying
     -------                                                                 
     any Indemnifying Party shall relieve the Indemnifying Party from any
     obligation hereunder unless (and then solely to the extent) the
     Indemnifying Party thereby is prejudiced.

          (ii)  Any Indemnifying Party will have the right to defend the
     Indemnified Party against the Third Party Claim with counsel of its choice
     reasonably satisfactory to the Indemnified Party so long as (A) the
     Indemnifying Party notifies the Indemnified Party in writing within 30 days
     after the Indemnified Party has given notice of the Third Party Claim that
     the Indemnifying Party will indemnify the Indemnified Party from and
     against the entirety of any Adverse Consequences the Indemnified Party may
     suffer resulting from, arising out of, relating to, in the nature of, or
     caused by the Third Party Claim, (B) the Indemnifying Party provides the
     Indemnified Party with evidence reasonably acceptable to the Indemnified
     Party that the Indemnifying Party will have the financial resources to
     defend against the Third Party Claim and fulfill its indemnification
     obligations hereunder, (C) the Third Party Claim involves only money
     damages and does not seek an injunction or other equitable relief, (D)
     settlement of, or an adverse judgment with respect to, the Third Party
     Claim is not, in the good faith judgment of the Indemnified Party, likely
     to establish a precedential custom or practice [materially] adverse to the
     continuing business interests of the Indemnified Party, and (E) the
     Indemnifying Party conducts the defense of the Third Party Claim actively
     and diligently.

          (iii) So long as the Indemnifying Party is conducting the defense of
     the Third Party Claim in accordance with Section 4 (d)(ii) above, (A) the
     Indemnified Party may retain separate co-counsel at its sole cost and
     expense and participate in the defense of the Third Party Claim, (B) the
     Indemnified Party will not consent to the entry of any judgment or enter
     into any settlement with respect to the Third Party Claim without the prior
     written consent of the Indemnifying Party, and (C) the Indemnifying Party
     will not consent to the entry of any judgment or enter into any settlement
     with respect to the Third Party Claim without the prior written consent of
     the Indemnified Party (not to be withheld unreasonably). In the event any
     of the conditions in Section 4(d)(ii) above is or becomes unsatisfied,
     however, (A) the Indemnified Party may defend against, and consent to the
     entry of any judgment or enter into any settlement with respect to, the
     Third Party Claim in any manner it reasonably may deem appropriate (and the
     Indemnified Party need not consult with, or obtain any consent from, any
     Indemnifying Party in connection therewith), (B) the Indemnifying Parties
     will reimburse the Indemnified Party promptly and periodically for the
     costs of defending against the

                                       9
<PAGE>
 
     Third Party Claim (including reasonable attorneys' fees and expenses), and
     (C) the Indemnifying Parties will remain responsible for any Adverse
     Consequences the Indemnified Party may suffer resulting from, arising out
     of, relating to, in the nature of, or caused by the Third Party Claim to
     the fullest extent provided in this Section 4.

     (e)  Determination of Adverse Consequences. The Parties shall take into
          --------------------------------------              
account the time cost of money (using the Applicable Rate as the discount rate)
in determining Adverse Consequences for purposes of this (S)4. All
indemnification payments under this Section 4 shall be deemed adjustments to the
Purchase Price.

     (f)  Recoupment Under The Notes. The Buyer shall have the option of 
          ---------------------------                                   
recouping all or any part of any Adverse Consequences it may suffer (in lieu of
or in addition to seeking any indemnification to which it is entitled under this
Section 4) by notifying any Seller Stockholder that the Buyer is reducing the
principal amount outstanding under any of the Notes. This shall affect the
timing and amount of payments required under the Notes in the same manner as if
the Buyer had made a permitted prepayment (without premium or penalty)
thereunder.

     (g)  Other Indemnification Provisions. The foregoing indemnification 
          ---------------------------------                              
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy any Party may have for breach of representation,
warranty, or covenant. Each of the Seller Stockholders hereby agrees that he or
it will not make any claim for indemnification against any of the Buyer and its
Subsidiaries by reason of the fact that he or it was a director, officer,
employee, or agent of any of the Seller or was serving at the request of any
such entity as a partner, trustee, director, officer, employee, or agent of
another entity (whether such claim is for judgments, damages, penalties, fines,
costs, amounts paid in settlement, losses, expenses, or otherwise and whether
such claim is pursuant to any statute, charter document, bylaw, agreement, or
otherwise) with respect to any action, suit, proceeding, complaint, claim, or
demand brought by the Buyer against such Seller Stockholder (whether such
action, suit, proceeding, complaint, claim, or demand is pursuant to this
Agreement, applicable law, or otherwise).

     (h)  Buyer's Failure to Make Payments Under The Notes. In the event the
          -------------------------------------------------     
Buyer fails to make any payment under any of the Notes described in the Section
2(b) of the Asset Purchase Agreement or required by the Earn Out and the failure
is not cured within 120 days after written notice to the Buyer pursuant to
Section 5(h) below, the Seller Stockholders shall be relieved of the
restrictions set forth in of Sections 3(d) and (e) of this Agreement.

     5. Miscellaneous.

     (a) Press Releases and Public Announcements.  None of the Seller 
         ----------------------------------------                   
Stockholders shall issue any press release or make any public announcement
relating to the subject matter of the Asset Purchase Agreement without the prior

         ----------------------------

successors and permitted assigns.

hereof.

         --------------------------                                     
inure to the benefit of the Parties named herein and their respective successors
and permitted assigns. No Party may assign either this Agreement or any of his
rights, interests, or obligations hereunder without the prior written approval
of the Buyer and the Requisite Seller Stockholders; provided, however, that the
Buyer may (i) assign any or all of its rights and interests hereunder to one or
more of its Affiliates and (ii) designate one or more of its Affiliates to
perform its obligations hereunder (in any or all of which cases the Buyer
nonetheless shall remain liable and responsible for the performance of all of
its obligations hereunder).

     (e) Counterparts. This Agreement may be executed in one or more 
         -------------                                              
counterparts, each of which shall be deemed an original but all of which
together will constitute one and the same instrument.

     (f) Headings. The section headings contained in this Agreement are inserted
         ---------                                                     
for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

     (g) Notices. All notices, requests, demands, claims, and other
         --------

     (h) Governing Law. This Agreement shall be governed by and construed in

accordance with the domestic laws of the State of California without giving
effect to any choice or conflict of law provision or rule (whether of the State
of California or any other jurisdiction) that would cause the application of the
laws of any other jurisdiction.

     (i) Amendments and Waivers. No amendment of any provision of this Agreement
         -----------------------                                      
shall be valid unless the same shall be in writing and signed by the Buyer and
the Requisite Seller Stockholders. No waiver by any Party of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

     (j) Severability. Any term or provision of this Agreement that is invalid
         -------------                                                
or unenforceable in any situation in any jurisdiction shall not affect the

validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

     (k) Expenses. Each of the Parties will bear his own costs and expenses
         ---------

         -------------                                             
and drafting of this Agreement. In the event an ambiguity or question of intent
or interpretation arises, this Agreement shall be construed as if drafted
jointly by the Parties and no presumption or burden of proof shall arise
favoring or disfavoring any Party by virtue of the authorship of any of the
provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation.

     (m) Incorporation of Exhibits, Annexes and Schedules. The Exhibits, Annexes
         -------------------------------------------------              
and Schedules identified in this Agreement are incorporated herein by reference

     (n) Specific Performance. Each of the Parties acknowledges and agrees that
         ---------------------                                            
the other Parties would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached. Accordingly, each of the Parties agrees that
the other Parties shall be entitled to an injunction or injunctions to prevent
breaches of the provisions of this Agreement and to enforce specifically this

<PAGE>
 
Agreement and the terms and provisions hereof in any action instituted in any
court of the United States or any state thereof having jurisdiction over the
Parties and the matter (subject to the provisions set forth in Section 6(o)
below) in addition to any other remedy to which they may be entitled, at law or
in equity.

     (o) Submission to Jurisdiction. Each of the Parties submits to the
         ---------------------------                                   
jurisdiction of any state or federal court sitting in Orange County, California
in any action or proceeding arising out of or relating to this Agreement and
agrees that all claims in respect of the action or proceeding may be heard and
determined in any such court. Each Party also agrees not to bring any action or
proceeding arising out of or relating to this Agreement in any other court. Each
of the Parties waives any defense of inconvenient forum to the maintenance of
any action or proceeding so brought and waives any bond, surety, or other
security that might be required of any other Party with respect thereto. Each

          NOW, THEREFORE, THE PARTIES AGREE AS FOLLOWS:

                                  ARTICLE 1.
                       DEMISED PREMISES AND COMMON AREAS

1.01.  Lessor does hereby lease to Lessee, and Lessee does hereby rent from

                                  ARTICLE 2.
                                     TERM

2.01.  The term of this Lease shall be a period of Seven (7) years, commencing
on June 1, 1992, and ending on May 31, 1999, unless sooner terminated as
provided herein.

2.02.  If Lessor, for any reason whatsoever, is unable to deliver possession of
the Demised Premises to Lessee on the commencement date specified in Section
2.01 above, Lessor shall not be liable to Lessee for any loss or damage
resulting therefrom, nor shall this Lease be void or voidable, but in such event
Lessee shall not be liable for rent or other sums due Lessor until possession of
the Demised Premises is offered to Lessee. However, if Lessor is unable to
deliver premises by October 1, 1992, this lease shall become voidable at the
option of Lessee. No delay in delivery of possession shall operate to extend the
term hereof unless otherwise stipulated in writing by the parties.

2.03.  Provided that Lessee is not then in default in the performance of any of
Lessee's obligations hereunder, Lessee shall have the option to extend the term
for an additional period of five (5) years. Such option can only be exercised by
Lessee giving written notice thereof to Lessor at least one hundred twenty(120)
days prior to expiration of the initial term of the lease.

                                  ARTICLE 3.
                                     RENT

3.01.  Lessee shall pay to Lessor as Base Rent for the Demised Premises, in
lawful money of the United States, payable in advance on or before the first day
of each calendar month without any deduction, offset or demand, the following
amounts:(a) During the first five (5) years of the lease term, the Base Rent
shall be the sum of EIGHT THOUSAND SIX HUNDRED TWENTY FOUR DOLLARS AND 00/100
($8,624.00).

       (a) The Base Rent shall be increased at the beginning of the 6th year of
this Lease based upon the percentage increase, if any, in the Consumer Price
Index of the Bureau of Labor Statistics, U. S. Department of Labor, for Urban
Wage Earners and Clerical Workers, Oakland-San Francisco Area, All Items
("C.P.I."). The amount of such increase shall be calculated by multiplying the
Base Rent provided in Paragraph (a) of this Section by a fraction, the numerator
of which shall be the C.P.I. for the month in which the adjustment is made, and
the denominator of which shall be the C.P.I. for the calendar month in which the
initial term of this lease commences. The sum so calculated shall be added to
the Base Rent provided in paragraph 3.01 and shall constitute the Adjusted Base
Rent payable during the term pursuant to paragraph 3.01 of this Lease. In no
event shall the Base Rent be reduced below the amount provided in Paragraph 3.01
of this Section. In no event shall the rent increase more than 25% over the base
rent for the one time increase in the 6th year of this lease.

       Pending receipt of the required C.P.I. and determination of the actual
       adjustment, Lessee shall pay an estimated adjusted rental, as reasonably
       determined by Lessor according to C.P.I. information then available. Upon
       notification of the actual adjustment, any overpayment shall be credited
       against the next installment of rent due, and any

                                       2
<PAGE>
 
       underpayment shall be immediately due and payable by Lessee. Lessor's
       failure to request payment of an estimated or actual rent adjustment
       shall not constitute a waiver of the right to any rental adjustment
       provided herein.

       (b) In the event Lessee exercises the option to extend the lease term for
the five (5) year period as provided in Section 2.03, the rent payable during
the extended term shall be pursuant to Article 3.01 (c).

       (c) Lessor grants to Lessee (1) one option to extend the term of this
Lease for (5) five years, beginning on the expiration of the original term of
this Lease at 95% fair market value to be mutually agreed upon and subject to
all other terms covenants and conditions contained herein. However, if Lessor
and Lessee cannot agree on a "fair market value", it will be submitted for
arbitration by choosing three Real Estate appraisers; one by Lessor, one by
lessee and the third by the first two appraisers. Lessee shall give Lessor
written notice at least one hundred twenty (120) days prior to the expiration
date of this Lease of Lessee's intention to exercise said option granted herein.
In order for Lessee to avail itself of said option period, Lessee must have
lived up to and observed the timely performance of all terms covenants and
conditions contained in the Lease Agreement. In no event shall the rent be less
than that rent paid at the end of the original seven (7) year term.

3.02.  If the commencement date is not the first day of a calendar month, or if
the termination date is not the last day of a calendar month, the monthly rental
for the fractional month shall be prorated on the basis of a thirty (30) day
month.

3.03.  Lessee acknowledges that late payment of rent and any other charges
provided herein will cause Lessor to incur costs not contemplated by this Lease,
the exact amount of such costs being extremely difficult and impracticable to
determine. Such costs include, without limitation, processing and accounting
charges, late charges that may be imposed on Lessor by the terms of any
encumbrances against the Industrial Building and penalties on delinquent tax
payments. Lessee therefore agrees that if any installment of rent or other
charge payable by Lessee hereunder is not received by Lessor within ten (10)
days after the same becomes due, Lessor shall be entitled to collect an
additional sum equal to one and one-half percent (1.5%) of the delinquent
payment for each month or fraction thereof that the rent or other charge remains
unpaid. Acceptance of any late charge shall not constitute a waiver of Lessee's
default with respect to the overdue amount, nor prevent Lessor from exercising
any other rights and remedies available to Lessor hereunder or provided by law.

                                  ARTICLE 4.
                               SECURITY DEPOSIT

4.01.  Lessee has deposited with Lessor the sum of($8,624.00) as and for a
security deposit. Upon adjustment of the Base Rent in accordance with Section
3.01, the security deposit shall be increased to an amount equal to the Adjusted
Base Rent for one (1) month and Lessee shall promptly deposit the increase with
Lessor.

                                       3
<PAGE>
 
4.02.  If Lessee defaults with respect to any provision of this Lease, Lessor
may use, apply or retain all or any part of the security deposit to cure such
default or to compensate Lessor for all damages sustained by Lessor resulting
from Lessee's default. If any portion of said deposit is so used or applied,
Lessee shall within ten (10) days after written demand therefor, deposit cash
with Lessor in an amount sufficient to restore the security deposit to its
original amount, and Lessee's failure to do so shall constitute a material
breach of this Lease. Lessor's obligations with respect to the security deposit
are those of a debtor and not a trustee. Lessor shall not be required to
segregate the security deposit as a separate fund and Lessee shall not be
entitled to any interest thereon. If Lessee shall fully and faithfully perform
every provision of this Lease to be performed by Lessee, the security deposit or
any balance thereof shall be returned to Lessee within thirty (30) days after
termination of the Lease.

                                  ARTICLE 5.
                                      USE

5.01.  The Demised Premises shall be used and occupied by Lessee solely for
Office/Warehouse and for no other or additional purpose without the prior
written consent of Lessor.

5.02.  Lessee shall not use the Demised Premises or permit anything to be done
in or about the Demised Premises which is prohibited by or will in any way
conflict with any law, statute, ordinance or governmental rule or regulation now
in force or which may hereafter be in force, or which is prohibited by the
standard form of fire insurance policy, or will in any way increase the existing
rate of any fire or other insurance covering the Industrial Building or any of
its contents, or cause any change or cancellation of such insurance. The
judgment of any court of competent jurisdiction or the admission of Lessee in
any action against Lessee, whether Lessor be a party thereto or not, that Lessee
has violated any law, statute, ordinance or governmental rule, regulation or
requirement,, shall' be conclusive of that fact as between Lessor and Lessee.
Lessee shall not do or permit anything to be done in or about the Demised
Premises which will in any way obstruct or interfere with the rights of other
tenants in the Industrial Building, or injure or annoy them, or use or allow the
Demised Premises to be used for any improper, immoral, unlawful or objectionable
purpose, nor shall Lessee cause, maintain or permit any nuisance in, on or about
the Demised Premises or commit or suffer to be committed any waste in, on or
about the Demised Premises.

                                  ARTICLE 6.
                            LEASEHOLD IMPROVEMENTS

6.01.  Lessor shall perform, at Lessor's own expense, the alterations and
improvements to the Demised Premises as described in "Exhibit A-1," attached
hereto and made a part hereof. Acceptance of the Demised Premises shall
constitute acceptance of any alterations and improvements therein performed by
Lessor and shall further constitute an acknowledgment by Lessee that the Demised
Premises are in good order, condition, and repair. Lessee, however, shall have
30 days from occupancy to submit a written "punch list" to Lessor of items to be
corrected by Lessor At Lessor's expense. Lessor shall have thirty (30) days to
complete items submitted by Lessee for correction.

and Lessor hereby consents to the performance of such work. Lessee may have

the purpose' of installing Lessee's improvements, provided that such work does
not obstruct or interfere with the work being performed therein by Lessor. No
delay by Lessee in the completion of Lessee's work, shall delay commencement of
the lease term on the date specified in Section 2.01, unless such delay was
directly and primarily caused by Lessor. Lessor may submit a bid to Lessee for

                                 CONDEMNATION

13.01.  If all of the Demised Premises or so much thereof is taken by right of
eminent domain, or purchase in lieu thereof, such that the Demised Premises are
no longer reasonably suitable for Lessee's use, this Lease shall terminate as of
the date that possession of the Demised Premises or part thereof is taken.

13.02.  If any part of the Demised Premises is taken and the remaining part
thereof (after reconstruction of the then existing building) is reasonably
suitable for Lessee's use, this Lease shall, as to the part so taken, terminate
as of the date that possession of such part is taken and the rent payable
hereunder shall be reduced in the same proportion that the floor area of the
portion of the Demised Premises so taken (less any addition thereto by reason of
any reconstruction) bears to the original floor area of the Demised Premises
immediately prior to the taking. Lessor shall, at Lessor's expense, make all
necessary repairs or alterations to restore the remaining Demised Premises to a
complete architectural unit.

13.03.  No award for any partial or entire taking shall be apportioned and
Lessee hereby assigns to Lessor all of Lessee's interest therein, except that
Lessee shall be entitled to any portion of the award specifically designated as
compensation for the taking of personal property belonging to Lessee, for the
interruption of Lessee's business, for Lessee's moving costs or loss of goodwill
suffered by Lessee. No temporary taking of the Demised Premises shall terminate
this Lease or give Lessee any right to abatement of rent hereunder; any award
recovered by Lessee for such temporary taking shall belong entirely to Lessee
and Lessor shall have no interest therein. Each party agrees to execute and
deliver to the other all instruments and documents that may be required to
implement the provisions of this Section.

                           ASSIGNMENT AND SUBLETTING

14.01.  Lessee shall not voluntarily or by operation of law assign, transfer,
mortgage, sublet, pledge, hypothecate or encumber all or any part of Lessee's
interest in this Lease or in the Demised Premises or any part thereof, without
Lessor's prior written consent and any attempt to do so without such consent
being first had and obtained shall be wholly void and shall constitute a breach
of this Lease. If Lessee is a corporation or partnership, any transfer of a
controlling interest in the stock of Lessee shall constitute an assignment
hereunder.

14.02.  If Lessee complies with the following conditions, Lessor shall not
unreasonably withhold Lessor's consent to the assignment of this Lease or the
subletting of the Demised Premises or any portion thereof. Lessee shall submit
in writing to Lessor:

        (a) The name and legal composition of the proposed Assignee or
Sublessee;

        (b) The terms and provisions of the proposed Assignment or Sublease; and

                                       10
<PAGE>
 
        (c) Such financial information as Lessor may reasonably request
concerning the proposed Assignee or Sublessee.

14.03.  No consent by Lessor to any assignment or subletting by Lessee shall
relieve Lessee of any obligation to be performed by Lessee under this Lease,
whether occurring before or after such consent, assignment or subletting. The
consent by Lessor to any assignment or subletting shall not relieve Lessee from
the obligation to obtain Lessor's express written consent to any other
assignment or subletting. The acceptance of rent by Lessor from any other person
shall not be deemed to be a waiver by Lessor of any provisions of this Lease or
to be a consent to any assignment, subletting or other transfer. Consent to one
assignment, subletting or other transfer shall not be deemed to constitute
consent to any subsequent assignment, subletting or other transfer.

                                  ARTICLE 15.
                         TRANSFER OF LESSOR'S INTEREST

15.01.  Lessor shall have the right at any time to sell, transfer, assign,
pledge, hypothecate or otherwise dispose of Lessor's interest in the Demised
Premises and in this Lease. In the event of any such sale, transfer, assignment,
pledge, hypothecation or other disposition, all obligations of Lessor hereunder
from and after the date of such transfer shall devolve upon the transferee and
Lessor shall be released and discharged from all further obligation or liability
hereunder; provided, that Lessor shall be responsible for any funds in the hands
of Lessor in which Lessee has an interest until such funds have been delivered
to the transferee. Lessee agrees to attorn to the transferee provided all of
Lessor's obligations hereunder from and after the date of such transfer are
assumed by the transferee in writing for the benefit of Lessee.

                                  ARTICLE 16.
                               MECHANICS' LIENS

16.01.  Lessee shall keep the Demised Premises free and clear of all mechanics'
liens resulting from any construction work done by or for Lessee. Lessee shall
have the right to contest. the correctness or validity of any such lien if,
immediately on demand by Lessor, Lessee procures and records a lien release bond
issued by a corporation authorized to issue surety bonds in California in an
amount equal to one and one-half (1-1/2) times the amount of the claim of lien
or other security satisfactory to Lessor. If used, the bond shall meet the
requirements of Section 3143 of the California Civil Code and shall provide for
the payment of any sum that the claimant may recover on the claim, together with
costs of suit. Should Lessee fail to discharge any such lien or cause the same
to be released within sixty (60) days from the date the lien is filed, Lessor
may, without inquiring into the validity thereof, cause the same to be
discharged and all amounts so expended by Lessor, together with reasonable
attorney's fees and expenses, shall be paid by Lessee to Lessor as additional
rent hereunder, together with interest thereon at the rate of fifteen percent
(15%) per annum. Lessee shall give ten (10) days prior written notice to Lessor
of the date on which any construction work will be commenced so as to afford
Lessor the opportunity to post a notice of nonresponsibility.

inconvenience to or interference with Lessee's business, any-loss of occupancy
or quiet enjoyment of the Demised Premises or any other loss occasioned by
Lessor's entry pursuant to Section 17.01. Lessor shall at all times have and
retain a key with which to unlock all of the doors in, on or about the Demised
Premises (excluding Lessee's vaults, safes and other secured areas designated in
writing by Lessee in advance); and Lessor shall have the right to use any and
all means which Lessor may deem proper to open said doors in an emergency in
order to obtain entry to the Demised Premises, and any entry to the Demised
Premises obtained by Lessor by any of said means, or otherwise, shall not under
any circumstances be construed or deemed to be a forcible or unlawful entry into
or a detainer of the Demised Premises, or an eviction, actual or constructive,
of Lessee from the Demised Premises, or any portion thereof.

                                  ARTICLE 18.

<PAGE>
 
        (a) With (10) ten days written notice from Lessor, any failure by Lessee
to pay any rental or any other sum required to be paid by Lessee hereunder, as
and when the same becomes due and payable.

        (b) Any failure by Lessee to observe and perform any other provision of
this Lease to be observed or performed by Lessee, where such failure continues
for ten (10) days after written notice thereof by Lessor to Lessee; provided,
however, that if the nature of such default is such that it cannot reasonably be
cured within such ten (10) day period, Lessee shall not be deemed to be in
default if Lessee shall within such period commence such cure and thereafter
diligently prosecute the same to completion.

        (c) The making by Lessee of any general assignment or general
arrangement for the benefit of creditors; the filing by or against Lessee of a
petition to have Lessee adjudged a bankrupt or a petition for reorganization or
arrangement under any law relating to bankruptcy (unless, in the case of a
petition filed against Lessee, the same is dismissed within ninety (90) days);
the appointment of a trustee or receiver to take possession of substantially all
of Lessee's interest in this Lease, where possession is not restored to Lessee
within sixty (60) days; or the attachment, execution or other judicial seizure
of substantially all of Lessee's assets located at the Demised Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within
forty-five (45) days.

18.02.  Any notice given under this Article shall specify the Event of Default
and the applicable lease provisions, and shall demand that Lessee perform the
provisions of this Lease, within the applicable period of time. No such notice
shall be deemed a forfeiture or a termination of this Lease provided Lessee
cures the default within the applicable period of time.

                                  ARTICLE 19.
                        LESSOR'S REMEDIES UPON DEFAULT

19.01.  Lessor shall have the following remedies upon the occurrence of an Event
of Default, such remedies being cumulative and not exclusive and in addition to
any other remedies available to Lessor as now or hereafter provided by law:

        (a) Lessor can continue this Lease in full force and effect, and the
Lease will continue in effect as long as Lessor does not terminate Lessee's
right to possession, and Lessor shall have the right to collect rent when due,
irrespective of whether Lessee shall have abandoned the Demised Premises. During
the period Lessee is in default, Lessor can enter the Demised Premises and relet
them, or any part of them, to third parties for Lessee's account. Lessee shall
be liable immediately to Lessor for all costs Lessor incurs in such reletting,
including, without limitation, broker's commissions, expenses of remodeling the
Demised Premises required by reletting, and like costs. Reletting can be for a
period shorter or longer than the remaining term of this Lease. Lessee shall pay
to Lessor the rent specified in this Lease on the dates when the same becomes
due, less the rent Lessor receives from any reletting. No act by Lessor allowed
by this paragraph shall terminate this Lease unless Lessor notifies Lessee that
Lessor elects to terminate this Lease. After Lessee's default and for as long as
Lessor does not terminate Lessee's right to possession of the Demised Premises,
Lessee shall have the right to assign or sublet Lessee's 

                                       13
<PAGE>
 
interest in this Lease pursuant to Article 14, but Lessor's consent may be
conditioned upon all defaults by Lessee being fully cured at the time of
assignment or subletting.

        (b) Lessor can terminate Lessee's right to possession of the Demised
Premises at any time during Lessee's default. No act by Lessor other than giving
written notice to Lessee shall terminate this Lease. Acts of maintenance,
efforts to relet the Demised Premises, or the appointment of a receiver on
Lessor's initiative to protect Lessor's interest under this Lease shall not
constitute a termination of Lessee's right to possession. On termination, Lessor
has the right to recover from Lessee:

            (1) The worth, at the time of the award, of the unpaid rent that has
been earned at the time of termination of this Lease; plus

            (2) The worth, at the time of the award, of the amount by which the
unpaid rent that would have been earned after the date of termination of this
Lease until the time of award exceeds the amount of the loss of rent that Lessee
proves could have been reasonably avoided; plus

            (3) The worth, at the time of the award, of the amount by which the
unpaid rent for the balance of the term after the time of award exceeds the
amount of the loss of rent that Lessee proves could have been reasonably
avoided; and

            (4) Any other amount, and court costs, necessary to compensate
Lessor for all detriment proximately caused by Lessee's default.

            "The worth, at the time of the award," as used in (1) and (2) above,
is to be computed by allowing interest at the rate of ten percent (10%) per
annum from the date of default. "The worth, at the time of the award" as used in
(3) above is to be computed by discounting the amount at the discount rate of
the Federal Reserve Bank of San Francisco at the time of the award, plus one
percent (1%). The term "rent," as used in this Article shall be deemed to
include all monetary sums required to be paid by Lessee pursuant to the terms of
this Lease.

                                  ARTICLE 20.
                        LESSOR'S RIGHT TO CURB DEFAULTS

20.01   If Lessee shall fail to pay any sum of money, other than rent, required
to be paid by Lessee hereunder, or shall fail to perform any other act on
Lessee's part to be performed hereunder, and such failure shall continue for ten
(10) days after notice thereof by Lessor, Lessor may, but shall not be obligated
to do so, and without waiving or releasing Lessee from any obligations of
Lessee, make such payment or perform any such other act on Lessee's part to be
made or performed hereunder. All sums expended by Lessor, including necessary
incidental costs, shall be deemed additional rent hereunder and shall be payable
to Lessor immediately upon demand, together with interest thereon at the rate of
fifteen percent (15%) per annum from the date of expenditure to the date of
reimbursement.

                                 COSTS OF SUIT

21.01.  In the event legal action between Lessor and Lessee shall become
necessary in order to enforce or interpret this Lease, or any provision
contained herein, the prevailing party shall be entitled to recover all costs
and expenses as may be incurred in connection therewith, including reasonable
attorney's fees.

21.02.  Should Lessor, without fault on Lessor's part, be made a party to any
litigation instituted by Lessee or by any third party against Lessee, or by or
against any person holding under or using the Demised Premises by license of
Lessee, or for the foreclosure of any lien for labor or materials furnished to
or for Lessee or any such other person or otherwise arising out of or resulting
from any act or transaction of Lessee or of any such other person, Lessee
covenants to save and hold Lessor harmless from any judgment rendered against
Lessor or the Demised Premises or any part thereof, and all costs and expenses,
including reasonable attorney's fees, incurred by Lessor in connection with such
litigation.

                                  ARTICLE 22.
                                 SUBORDINATION

22.01.  In the event the holder of any deed of trust hereafter to be placed
against the Demised Premises requires that this Lease be subordinate to any such
encumbrance, this Lease shall be subordinate to that encumbrance if Lessor first
obtains from the holder of the deed of trust a written agreement providing that
for so long as Lessee' shall perform all of Lessee's duties and obligations
hereunder, no foreclosure, deed given in lieu of foreclosure or sale under such
deed of trust shall affect Lessee's rights under this Lease. Lessee shall attorn
to any purchaser at any foreclosure sale, or to any grantee or transferee
designated in any deed given in lieu of foreclosure. Lessee shall execute the
written agreement and any other documents required by the holder of the deed of
trust to accomplish the purposes of this Article, and upon Lessee's failure or
refusal to do so within five (5) days after demand, Lessee hereby appoints
Lessor as Lessee's attorney-in-fact to execute such agreement or other documents
for and on behalf of Lessee. The power of attorney granted herein shall be
deemed to be coupled with an interest and to be irrevocable.

                                  ARTICLE 23.
                             ESTOPPEL CERTIFICATE

23.01.  Each party, within ten (10) days after notice from the other, shall
execute and deliver to the other, in recordable form, a certificate stating that
this Lease is unmodified and in full force and effect, or in full force and
effect as modified stating the modifications. The certificate also shall state
the amount of monthly rent, the dates to which the rent has been paid in
advance, the amount of any security deposit or prepaid rent, and shall further
certify that there is no uncured default by the other party under the Lease, or
specify such default, if any is claimed. Failure to deliver the certificate
within the ten (10) days, shall be conclusive upon the party failing to deliver
the certificate for the benefit of the party requesting the certificate, and any
successor to the party requesting the certificate, that this Lease is in full
force and effect and has not been 

                                       15
<PAGE>
 
modified except as may be represented by the party requesting the certificate,
that there are no uncured defaults by the party requesting the certificate and
that not more than one (1) month's rent has been paid in advance.

                                  ARTICLE 24.
                                 HOLDING OVER

24.01.  If Lessee remains in possession of all or any part of the Demised
Premises after the expiration of the term hereof, with the express or implied
consent of Lessor, such tenancy shall be from month to month only, and not a
renewal hereof or an extension for any further term and in such case rent and
other monetary sums due hereunder shall be the amount payable at the expiration
of the term of this Lease and such month to month tenancy shall be subject to
every other term, covenant and agreement contained herein.

                                  ARTICLE 25.
                                   SURRENDER

25.01.  Upon the expiration or earlier termination of this Lease, Lessee shall
surrender the Demised Premises in the same condition as received, ordinary wear
and tear and damage by fire, earthquake, act of God or the elements alone
excepted. Lessee shall remove all of Lessee's personal property and trade
fixtures and shall repair, at Lessee's expense, any damage to the Demised
Premises or the Industrial Building caused by such removal, including, without
limitation, repair of floors and patching and repainting of walls where
required, all to Lessor's reasonable satisfaction. Any personal property or
trade fixtures not removed at the expiration or earlier termination of this
Lease shall be deemed abandoned by Lessee. If Lessor so elects, Lessee shall
also remove any alterations or improvements installed by or for Lessee which
would otherwise remain as part of the Demised Premises and Lessee shall restore
the Demised Premises to their condition prior to such installation.

25.02.  Should Lessee fail to remove any personal property or trade fixtures, or
fail to remove any alterations or improvements as requested by Lessor, Lessee
shall be liable to Lessor for any and all removal costs, transportation and
storage expenses, and the cost of restoring the Demised Premises as required
herein. Lessee shall indemnify Lessor against any loss, damage or liability
resulting from delay by Lessee in so surrendering the Demised Premises,
including, without limitation, any claims made by any succeeding tenants founded
on such delay.

                                  ARTICLE 26.
                                    WAIVER

26.01.  No covenant, term or condition or the breach thereof shall be deemed
waived, except by written consent of the party against whom the waiver is
claimed, and any waiver of any covenant, term or condition shall not be deemed
to be a waiver of any preceding or succeeding breach of the same or any other
covenant, term or condition. Acceptance by Lessor of any performance by Lessee
after the time the same shall have become due shall not constitute a waiver by
Lessor of the breach or default of any covenant, term or condition unless
otherwise 

                                       16
<PAGE>
 
expressly agreed to by Lessor in writing. The receipt and acceptance by Lessor
of delinquent rent shall constitute only a waiver of timely payment for the
particular rent payment involved.

                                  ARTICLE 27.
                                QUIET ENJOYMENT

          Lessor hereby covenants with Lessee that upon payment by Lessee of the
rent as aforesaid and upon observance and performance of the terms of this Lease
by Lessee, Lessee shall peaceably hold and enjoy the Demised Premises for the
term hereby demised without hindrance or interruption by Lessor or any person or
persons lawfully or equitably claiming by, through or under Lessor.

companies acceptable to and approved in writing by Landlord to protect against

commonly known as extended coverage and such other policies or endorsements of
insurance, with insurance companies authorized and licensed to issue such
policies in the State of California, in an amount not less than the full
replacement cost of the Building, excluding from said replacement cost the

Uniform Standard Building Form.  All such policies of insurance shall provide
that the proceeds thereof shall be payable to Landlord.  The one year annual
premium charged during any fiscal/calendar year, less any annual special hazard

determining the Tenant's share of insurance premium increases.  Thereafter,
Landlord shall pay all insurance premiums; provided, however, commencing with
the first annual premium due and payable after the expiration of the annual
policy term, any increase in the annual premium, after deducting all special

20.  ALTERATIONS

Premises nor make any contract therefore without obtaining Landlord's prior
written consent.  As a condition to giving such consent, landlord may require
that Tenant remove any such alterations, improvements or additions at the
expiration of the term of this lease and to restore the Premises to the
condition prior to making same provided that if Landlord does not so requires
such removal then, to the extent not required, all such alterations, additions
or improvements shall, upon the expiration of the term hereof, become the sole
property of Landlord (excepting that in any event Tenant shall be permitted and
shall remove its signs and trade fixtures).

                                       8
<PAGE>
 
          Before commencing any work relating to alterations, additions and
improvements affecting the Premises, Tenant shall notify Landlord in writing of
the expected date of commencement thereof. Landlord shall then have the right at
any time and from time to time to post and maintain on the Premises such notices

agents or contractors in connection with work of any character performed or
claimed to have been performed on the Premises by or at the direction of Tenant.

21.  SIGNS

          Landlord reserves the right to the use of the exterior walls and the
roof of the Premises and the Building.  Tenant shall not inscribe, paint or
affix any signs, advertisements, placards or awnings on the exterior or roof of
the Premises or upon the entrance doors, windows, or the sidewalk on or adjacent
to the Premises without the prior written consent of Landlord.  Any signs so
place in the Premises shall be so placed upon the understanding and agreement
that Tenant, at Tenant's sole cost and expense shall remove same at expiration
or termination of this Lease and will repair any damage or injury to the
premises caused thereby, and if not so removed by Tenant, Landlord may remove it
at Lessee's expense.

          Tenant shall order its Building and/or directory signs through CRI
Properties.  All of the signs must be conforming as to City approved form and
any applicable CC&R's.  If Tenant has ordered its sign and is waiting for the
permanent sign, it may have a temporary sign approved by Landlord until the
permanent sign is installed.  Tenant shall be responsible for the cost of the
signs and installation.

22.  ASSIGNMENT AND SUBLETTING

          Tenant may assign this Lease or an interest therein and may also
sublet the whole of the Premises, provided the written consent of Landlord to
any such assignment or subletting is first obtained by Tenant.  If, during the
term of this Lease, Tenant requests the written consent of Landlord to any such
assignment or subletting, or both, Landlord's consent thereto shall not be
unreasonably withheld.  A consent to one assignment or subletting shall not be
deemed to be a consent to any subsequent assignment or subletting, and any such
subsequent assignment or subletting without Landlord's consent shall be void and
shall, at Landlord's option, terminate this Lease.  This Lease shall not, nor
shall any interest therein, be assignable as to the interest of Tenant by
operation of law without the written consent of Landlord, but such written
consent of Landlord shall not unreasonably be withheld.


     22.1 Options Are Nontransferrable.

          Each option to extend is granted by Landlord to Tenant personally, and
shall not be exercised or assigned, voluntarily or involuntarily, by or to
anyone other than Tenant.  Any 

                                       9
<PAGE>
 
assignment of the option to extend without Landlord's prior written consent
shall be void, and at Landlord's election shall constitute a default hereunder.
After the exercise of each option to extend and the commencement of the option
term, all preferences in this Lease to the term shall be considered to mean the
term as amended. The occurrence of a default as to the obligations of Tenant
hereunder shall automatically terminate and cancel all its existing options.

23.  DESTRUCTION OF PREMISES

          In the event of a total or partial destruction of the Premises from
any cause, Tenant shall give immediate notice thereof to Landlord and Landlord
shall forthwith repair the same, provided such repairs can be made within ninety
(90) days by working in the usual and ordinary manner without overtime or
other premium charges for expedited work or materials and under the laws and
regulations of State, County of Municipal authorities, but such destruction or
damage shall in no way annul or void this Lease.  Landlord's obligation to
repair shall not include the restoration or replacement of Tenant's trade
fixtures, equipment, merchandise or any improvements or alternations made by
Tenant to the Premises.  Tenant shall be required to restore or replace same in
the event of damage.  Tenant shall be entitled to a proportionate deduction of
rent while such repairs are being made (provided the destruction or damage shall
not have been caused by the fault or neglect of Tenant, its agents, servants,
employees or invitees), such proportionate deduction to be based upon the extent
to which the making of such repairs shall interfere with the business carried on
by Tenant in the Premises.  If such repairs cannot be made in said manner in
ninety (90) days, or such repairs cannot be made under such laws and
regulations, this Lease may be terminated at the option of either party.  In
respect to any damage or destruction which Landlord is obligated to repair or
may elect to repair under the terms of this paragraph, the provisions of Section
1932, Subdivision 2, and Section 1933, Subdivision 4, or the Civil Code of the
State of California, are waived by Tenant.  In the event that the Building be
damaged or destroyed to the extent of not less than 33-1/3% of the replacement
cost hereof, Landlord may, at Landlord's sole option, elect to terminate this
Lease, whether the Premises be injured or not.

24.  CONDEMNATION

          The word "condemnation" or "condemned" as used in this Lease shall
mean the exercise or, or intent to exercise the power of eminent domain, and
shall include a voluntary sale by Landlord to any such entity, either under
threat of condemnation or while condemnation proceedings are pending, and
"condemnation" shall occur upon the actual physical taking of possession by the
condemner.  If any part of the Premises shall be taken or condemned for a public
or quasi-public use, and a part thereof remains which is susceptible of
occupation hereunder, this Lease shall, as to the part so taken, terminate as of
the date of condemnation, and rent payable hereunder shall be adjusted so that
the Tenant shall be required to pay for the remainder of the Term only such
portion of such rent as the value of the part remaining after the condemnation
bears to the value of the entire Premises at the date of condemnation.  If all
the Premises, or such part thereof be taken or condemned so that there does not
remain a portion susceptible for occupation hereunder, this Lease shall
terminate as of the date of condemnation.

                                       10
<PAGE>
 
          If a part or all of the Premises be condemned, Landlord shall be
entitled to and shall receive the total amount of any award made with respect
thereto, regardless of whether the award is based on a single award or a
separate award as between Landlord and Tenant, and, if and to the extent that
any such award or awards shall be made to Tenant or to any person, firm, or
corporation claiming through or under Tenant, Tenant hereby irrevocably assigns
any and all such awards. No portion of any such award or awards shall be paid to
Tenant for any so-called bonus or excess value of this Lease by reason of the
relationship between the rental payable under this Lease and the fair rental for
the Premises at the time of condemnation. The foregoing notwithstanding,
landlord shall turn over to Tenant that portion of any such award received by
Landlord hereunder which is expressly attributable under the terms of the award
to Tenant's fixtures and equipment shall be the same proportion of the actual
award as said fixtures and equipment were of the entity's appraisal.

25.  OPERATION OF BUSINESS AND ABANDONMENT

          Tenant shall not vacate or abandon the Premises at any time during the
Term.  In this regard, Tenant shall be deemed to have abandoned the Premises
unless Tenant shall, during the entire Term of this Lease, conduct its business
in the Premises during the regular customary days and hours for such type of
business in the city of trade area in which the Premises is located.

26.  NUISANCE

          Tenant shall not commit or permit to be committed any public or
private nuisance, or any other act or thing prohibited by law or which may
disturb the quiet enjoyment of any tenant in the Building.

Premises at all reasonable times for the purpose of inspecting the same or for
the purpose of maintaining the Building or for the purpose of making repairs,
alterations or additions to any other portion of the Building, including the
erection and maintenance of such scaffolding, canopies, fences and props as may
be required, or for the purpose of posting notices of non-responsibility for
alterations, additions, or repairs, or for the purposes of placing upon the
Premises, the Building or the property in which the premises are located any
usual or ordinary "for sale" signs, without any rebate of rent and without any
liability to Tenant for any loss of occupation of quiet enjoyment of the
Premises, hereby occasioned; and shall permit Landlord and his agents, at any
time within thirty (30) days prior to the expiration of this Lease, to place
upon Premises any usual or ordinary "to let" or "to lease" signs and exhibit the
Premises to prospective tenants at reasonable hours.

28.  OWNER TO BE HELD HARMLESS; WAIVER OF CLAIMS

          Tenant, as a material part of the consideration to be rendered to
Landlord, hereby waives all claims against Landlord for damages to goods, wares,
and merchandise, in upon or about he Premises and for injuries including death
to Tenant, agents or third persons in or about he Premises from any cause
arising at any time, and Tenant will hold Landlord exempt and 

                                       11
<PAGE>
 
harmless from all claims and demands for damage or injury to any person,
including death, or to the goods, wares and merchandise of any person, arising
from the use of the Premises by Tenant, or from the failure of Tenant to keep
the Premises in good condition and repair, as herein provided. Landlord hereby
releases Tenant, and its officers, agents, employees and servants from any and
all claims or demands for damages, loss, expense or injury to the Premises or to
any property of Landlord in, about or upon the Premises, which is caused by or
results from perils, events, or happenings which are the subject of insurance
carried by the Landlord and in force at the time of any such loss; provided,
however, that such waiver shall be effective only to the extent permitted by the
insurance covering such loss and to the extent such insurance is not prejudiced
thereby.

29.  DEFAULT

          In the event of any breach of this Lease by Tenant, then Landlord,
besides other rights and remedies he may have at law or in equity, shall have
the immediate right of re-entry and may remove all persons and property from the
premises.  If Landlord's right of re-entry is exercised following abandonment of
the premises by Tenant, then Landlord may consider any personal property
belonging to Tenant and left on the Premises to also have been abandoned, in
which case Landlord may dispose of all such personal property in any manner
Landlord shall deem proper and is hereby relieved of all liability for doing so.

          Should Tenant breach this Lease and abandon the Premises before the
end of the term hereof or if Tenant's right to possession is terminated by
Landlord because of any breach default, or failure of Tenant hereunder, then in
addition to any other rights or remedies available to Landlord hereunder by law
provided, Landlord shall have all the rights to either terminate the Lease, or
to not terminate the Lease and have said Lease continue in effect, as set forth
in California Civil Code Sections 1951.2 and 1951.4 and may have and recover
from Tenant all those items of damage set forth in either or both of said Code
Sections, in accord with their terms.  In determining the amount of damages
allowable under Paragraph (3) of Subdivision (a) of Civil Code Section 1951.2
the Landlord may recover and include only the worth at the time of award of the
amount by which the unpaid Rent for the balance of the Term after the time of
award exceeds the amount of such rental loss for the same period that Tenant
proves could be reasonably avoided.  In determining the amount of damage
allowable under Paragraph (4) of Subdivision (a) of Civil Code Section 1951.2
said items of detriment proximately caused by Tenant's failure to perform his
obligation under this Lease include, but are not limited to, court costs and
reasonable attorneys' fees for services in recovering possession, all costs and
expenses of any reletting including, without limitation, all costs and expenses
of any reletting including, without limitation, all cost of alterations and
repairs, dividing and subdividing of the Premises in connection therewith, all
brokerage commissions, attorneys' fees or other similar expenses of Landlord in
connection with such reletting.  All amounts due and unpaid from Tenant
hereunder shall bear interest at the rate of ten percent (10%) per annum from
its due date until paid.

against Tenant to take possession of the Premises and/or to collect the rents

Tenant then being carried on in the Premises and may take possession of any
personal property belonging to Tenant and used in the conduct of such business
and may use the same in conducting such business, on the Premises without
compensation to Tenant for such business, and may use the same in conducting
such business, on the Premises without compensation to Tenant for such use.
Neither the application for the appointment of such receiver, nor the
appointment of such receiver, shall be construed as an election on Landlord's
part to terminate this Lease unless a written notice of such intention is given
to Tenant by Landlord.

31.  INSOLVENCY OF TENANT

          Tenant agrees that in the event all or substantially all of its assets
be placed in the hands of a receiver or trustee, and in the event such
receivership or trusteeship continues for a period of ten (10) days, or should
Tenant make an assignment for the benefit of creditors, or be adjudicated a
bankrupt, or should Tenant institute any proceedings under the state or federal
bankruptcy act wherein Tenant seeks to be adjudicated a bankrupt, or seeks to be
discharged of its debts, or seeks an arrangement under Chapter 11 of the Federal
Bankruptcy Act, or should any involuntary proceedings be filed against such
Tenant under such bankruptcy laws and Tenant consents thereto or acquiesces
therein by default, then this Lease or any interest in and to this premises
shall not become an asset in any of such proceedings and in any of such events,
and in addition to any and all rights or remedies of Landlord hereunder or as
provided by law, it shall be lawful for Landlord at his option to declare the
Term hereof ended and re-enter the premises and take possession thereof and
remove all persons therefrom and Tenant shall have no further claim therein or

which may hereafter be in force. The judgment of any court of competent
jurisdiction, or the admission of Tenant in any action or proceeding against
Tenant, whether Landlord be a party thereto or not, that Tenant has violated any
such ordinance or statute in the use of the Premises, shall be conclusive of the
fact as between Landlord and Tenant.

subleases or sub-tenancies.

38.  WAIVER

          The waiver of Landlord of any breach of any term, covenant or
condition herein contained shall not be deemed to be a waiver of such term,
covenant or condition as to any subsequent breach of the same or as to any other
term, covenant or condition herein contained.  The subsequent acceptance of Rent
hereunder by Landlord shall not be deemed to be a waiver of any preceding breach
of Tenant of any term, covenant or condition of this Lease, other than the
failure of Tenant to pay the particular rental so accepted, regardless of
Landlord's knowledge of such preceding breach at the time of acceptance of such
rent.

39.  SUBORDINATION

          A.  Tenant, at its sole cost, shall comply with all laws relating to
the storage, use and disposal of hazardous Materials that Tenant, its agents,
employees, contractors or invited guests bring on the Premises or permit to be
brought on the Premises.  If Tenant does store, use, or dispose of any Hazardous

the Effective Date.

          B.  If the presence of Hazardous Materials on the Leased Premises
caused or permitted by Tenant or its agents, employees, or contractors either
before or after the Effective Date results in contamination or deterioration of
water or soil resulting in a level of permitted contamination greater than the
levels established by any governmental agency having jurisdiction over such
contamination, then Tenant shall promptly take any and all action necessary to
clean up such contamination if required by law or as a condition to the issuance
or continuing effectiveness of any governmental approval which relates to the
use of the Leased Premises or

<PAGE>
 
any part thereof. At any time prior to the expiration of the Lease Term, Tenant

required by law.

or may become contaminated by Hazardous Materials as a result of Tenant's
activities, Landlord may cause testing wells to be installed on or about he
Leased Premises or the Property in locations reasonably approved by Tenant, and
may cause the soils and ground water to be tested to detect the presence of
Hazardous Materials by the use of such tests as are then customarily used for
such purposes. If Tenant so requests, Landlord shall supply Tenant with copies
of such test results. The cost of such tests and of the installation,
maintenance, repair and replacement of such wells shall be paid by Landlord;
provided, however, that such cost shall be paid by Tenant if such tests detect
contamination of the Leased Premises by hazardous Materials which result from
Tenant's activity on the Leased Premises. Tenant shall have the right at any
time during the Lease Term to conduct its own test of the soils and ground water
underlying the Leased Premises or the Property by using such wells so long as
each of the following conditions are satisfied: (i) such tests are conducted by
Tenant at its own expense; (ii) Tenant repairs any damage to the Property or to
such wells caused by such tests; and (iii) Tenant delivers copies of the results
of such tests to Landlord.

          D.  It shall not be unreasonable for Landlord to withhold its consent
to any proposed Assignee or Tenant for Sublet pursuant to paragraph 15 of this
Lease if (i) the proposed Assignee or Tenant for Sublet's anticipated use of the
Leased Premises involves the generation, storage, use, treatment or disposal of
any Hazardous Material; (ii) the proposed Assignee or Tenant for Sublet has been
required by any prior landlord, lender or governmental authority to take
remedial action in connection with Hazardous Material contaminating a property
if the contamination resulted from such Assignee or Tenant for Sublet's actions
or use of the property in question; or (iii) the proposed Assignee or Tenant for
Sublet is subject to an enforcement order issued by any governmental authority
in connection with the use, disposal or storage of a Hazardous Material.

          E.  As used herein, the term "Hazardous Material" means any hazardous
or toxic substance, material or waste which is or becomes regulated by any local
governmental authority, the State of California or the United States Government.
The term "Hazardous Material" includes, without limitation, any material or
substance which is (i) listed under Article 9 or defined as hazardous or
extremely hazardous pursuant to Article II of Title 22 of the California
administrative code, Division 4, Chapter 20, (ii) defined as a "hazardous waste"
pursuant to Section 1004 of the Federal Resource Conservation and Recovery Act,
42 U.S.C. (S) 6901 et seq. (42 U.S.C. (S) 6903), or (iii) defined as a
"hazardous substance" pursuant to Section 

                                       18
<PAGE>
 
101 of the Comprehensive Environmental Response, Compensation and Liability Act,
42 U.S.C. (S) 9601 et seq. (42 U.S.C. (S) 9601).

                            OFFICE LEASE PROVISIONS
                            -----------------------

          This lease (this "Lease") is entered into by Landlord and Tenant as of
the reference date specified in Paragraph 1 of the Summary. All capitalized
terms used in this Lease and not defined in the body of this Lease shall have
the meaning given in the Summary.

          1.   Lease. Landlord hereby leases to Tenant, and Tenant hereby leases
               -----
from Landlord, the Premises described in Paragraph 7 of the Summary on the terms
and conditions set forth below.

          2.   Term. The Term of this Lease shall commence on the Commencement
               ----
Date specified in Paragraph 8 of the Summary and, unless terminated sooner
pursuant to the terms hereof, shall expire on the Expiration Date specified in
Paragraph 8 of the Summary. If Landlord, for any reason, cannot deliver
possession of the Premises to Tenant on the estimated Commencement Date, this
Lease shall not be void, nor shall Landlord be liable to Tenant for any loss
resulting therefrom, but Monthly Rent and other monetary obligations of Tenant
hereunder shall not commence until the Premises are delivered to Tenant.

          3.   Rent. During the Lease Term, Tenant shall pay to Landlord the
               ----
Monthly Rent set forth in Paragraph 9 of the Summary ("Monthly Rent"). Monthly
Rent shall be paid in advance, without deduction or offset, on the first day of
each calendar month and shall be paid at the address of Landlord specified in
Paragraph 3 of the Summary. Monthly Rent payable for any partial month shall be
prorated on the basis of a thirty (30) day month. Monthly Rent, Additional Rent
(as defined in Paragraph 6 below) and other amounts payable to Landlord by
Tenant under this Lease shall constitute "Rent."

          4.   Condition of Premises.
               ---------------------

               (a)  Prior to the commencement of the Lease Term, Landlord shall
cause to be performed in the Premises the improvements specified in Exhibit B
                                                                    ---------
attached hereto. Except as set forth in Exhibit B, Tenant accepts the Premises
                                        ---------
in their "as is" condition. Tenant's taking possession of the Premises shall be
conclusive evidence that the Premises were in good order and satisfactory
condition when Tenant took possession, except as to latent defects. No promise
of Landlord to alter, remodel, repair or improve the Premises or the Building
have been made by Landlord to Tenant, other than as may be contained herein or
in a separate work letter agreement signed by Landlord and Tenant.

               (b)  Tenant recognizes and understands that floors 2 through 5 of
the Building are currently being used for storage facilities by Landlord, and
may, at any time, be made available by Landlord for lease to third parties.
Landlord shall allocate Real Property Taxes and insurance premiums to the office
area as well as the storage floors; however, Landlord 

                                       1
<PAGE>
 
may charge all other categories of Operating Expenses that are reasonably
attributable exclusively to the office area to the tenants of the office area
exclusively. As used in this Lease, the term "office area" shall refer to the
rentable area of the Building made available by Landlord for lease to third-
party office tenants. In the event of an increase or decrease in the rentable
area of the Premises or the office area, Tenant's Prorata Share with respect to
Operating Expenses (other than insurance), as specified in Paragraph 11 of the
Summary, shall be appropriately adjusted. In addition, Tenant recognizes and
understands that the Building is in close proximity to a fire station and that
activities at that station may generate noise from time to time. Tenant agrees
that any such noise shall not constitute a constructive eviction from the
Premises by Landlord.

          5.   Security Deposit. Upon execution of this Lease, Tenant
               ----------------
shall pay to Landlord the Security Deposit set forth in Paragraph 10 of the
Summary as security for Tenant's compliance with the terms of this Lease. No
interest shall accrue on the Security Deposit. In no event shall the Security
Deposit be deemed or treated as prepaid rent for any rental installment due
hereunder whether for the last month installment or otherwise. Upon the
occurrence of an Event of Default (as defined in Paragraph 26(a), below) by
Tenant under this Lease, Landlord may, but shall not be obligated to, apply any
portion of the Security Deposit to cure the Event of Default or to compensate
Landlord for any expense or damage reasonably incurred by Landlord as a result
of the Event of Default. If all or part of the Security Deposit is used, Tenant
shall, immediately upon demand by Landlord, submit to Landlord the sum necessary
to return the Security Deposit to the original amount. Within a reasonable
period of time following the termination of this Lease and surrender of the
Premises by Tenant, Landlord shall return the remaining balance of the Security
Deposit to Tenant.

          6.   Additional Rent.
               ---------------

                         ------------------

               connection with the management, maintenance and repair of the

exceeded Tenant's obligations for the calendar year, Landlord shall, at its
option, either (1) credit the excess to the next succeeding installments of
Monthly Rent and/or estimated Additional Rent or (2) pay the excess to Tenant
within thirty (30) days after delivery of such statement. If the annual
statement shows that Tenant's payments of Additional Rent for such calendar year
pursuant to Paragraph 6(b) hereof were less than Tenant's obligation for the
calendar year, Tenant shall pay the deficiency to Landlord within fifteen (15)
days after delivery of such statement.

               (e)  Proration for Partial Lease Year. If this Lease terminates

the Lease terminates shall be prorated on the basis that the number of days from
the commencement of such calendar year to and including such termination date
bears to three hundred sixty (360).

          7.   Late Charge; Interest.
               ---------------------

               (a)  Late Charge. Tenant acknowledges that Tenant's failure to
                    -----------
pay Rent on time will result in additional accounting and other costs to
Landlord and that such costs are difficult to calculate. Therefore, Tenant
agrees that if Tenant fails to pay Monthly Rent, Additional Rent, or make any
other payment due Landlord under this Lease within ten (10) days of the date
due, Tenant will pay to Landlord a late charge equal to the greater of: (a) five
percent (5%) of the overdue sum; or (b) $150.

               (b)  Interest. If Rent is not received by Landlord within ten
                    --------
(10) days of the date due, interest shall accrue on such amount from the date
due until the date received by Landlord at an annual interest rate (the
"Interest Rate") equal to the lesser of (i) fifteen percent (15%), or (ii) the
highest rate allowed by law.

               (c)  Limitation on Grace Period. Notwithstanding the foregoing,
                    --------------------------
if Tenant fails to pay Rent by the actual date due more than four (4) times
during any twelve (12) month period, then, after such fourth (4th) late payment,
the ten (10) day grace periods provided for in Paragraphs 7 (a) and 7 (b) above
shall no longer apply and the late charge and interest provided for in those
Paragraphs shall commence to accrue on the actual due date until such time as
Tenant has timely made all payments due under this Lease for twelve (12)
consecutive 

                                       5
<PAGE>
 
months. Notwithstanding anything contained in the Lease, the provisions of this
Paragraph shall not be construed to grant Tenant a grace period and shall in no
way relieve Tenant of the obligation to pay any amount of Rent on or before the
date on which they become due, nor do the terms of this Paragraph in any way
affect Landlord's remedies pursuant to Paragraph 26 of the Lease in the event
any Rent remains unpaid after the due date.

          8.   Utilities and Services.
               ----------------------

               (a)  Description of Utilities and Services. Throughout the Lease
                    -------------------------------------
Term, Landlord shall provide to the Premises during the period of 8 A.M. to 5
P.M. ("Business Hours") Monday through Friday (except public holidays)
("Business Days"), and subject to governmental laws or the rules or actions of
the public utility company furnishing the service, the following: (i)
electricity for lighting and power suitable for the use of the Premises for
ordinary general office purposes; (ii) heat, ventilation and air conditioning
("HVAC") required in Landlord's judgment for the comfortable use and occupancy
of the Premises for such purposes; (iii) water for restroom and drinking
purposes; (iv) elevator service by nonattended automatic elevators for general
office pedestrian usage; (v) telecommunications intrabuilding network cabling;
and (vi) janitorial services. If Tenant requires HVAC to the Premises other than
during Business Hours on Business Days, Landlord shall, upon Tenants request
given not later than 3 P.M. of the Business Day on which Tenant requires the
after hour service, and not later than 3 P.M. on the Friday before any Saturday
or Sunday on which Tenant requires such service, and not later than 3 P.M. of
the day before any holiday on which Tenant requires such service, furnish such
HVAC. If Tenant receives such services, then Tenant shall pay, upon demand, an
amount equal to Tenant's proportionate share of the actual direct cost to
Landlord in providing the HVAC to Tenant and all other tenants of the Building
requesting such services outside of Business Hours on Business Days.

               (b)  Interruption of Services. In the event of an interruption in
                    ------------------------
any of the above described services or utilities, such interruption shall not
constitute an eviction of Tenant or impose upon Landlord any liability,
including liability for consequential damages or loss of business by Tenant.
Tenant hereby waives the provisions of California Civil Code Section 1932(1) or
any other applicable existing or future law permitting the termination of this
Lease due to such interruption.

               (c)  Governmental Controls. If any law (as defined in Paragraph
                    ---------------------
10, below) imposes controls or guidelines on Landlord or the Building relating
to the use or conservation of energy or utilities or other Building systems or
the reduction of automobile or other emissions (collectively "Controls"),
Landlord may comply with such Controls and such compliance shall not constitute
an eviction of Tenant or impose any liability upon Landlord.

          9.   Use. The Premises shall be used only for general office purposes
               ---
for the business of Tenant as described in Paragraph 13 of the Summary and for
no other use or purpose without the prior written consent of Landlord. Under no
circumstances shall the Premises or any 

                                       6
<PAGE>
 
portion of the Building be used for residential purposes. Tenant shall not do or
permit anything to be done in the Premises or the Building which would increase
the premium rate of or affect any fire, casualty, liability, rent or other
insurance relating to the Real Property. If any act or omission of Tenant
results in any such increase in premium rates, Tenant shall pay to Landlord upon
demand the amount of such increase. Tenant shall not do or permit anything to be
done in the Premises or the Building which will in any way interfere with the
rights of other occupants of the Building nor shall Tenant cause or permit any
nuisance in the Premises or the Building. Tenant agrees not to handle, store or
dispose of any substance on the Premises which is prohibited by federal, state
or local law or regulation.

          10.  Compliance with Law. Tenant, at its sole cost, shall promptly
               -------------------
comply with all laws, rules, regulations, covenants, conditions and restrictions
now in force or hereafter enacted (collectively, "laws") and with the
requirements of any board of fire underwriters or other similar body now or
hereafter constituted relating to the condition, use or occupancy of the
Premises (excluding structural changes to the Building not related to or
affected by Tenant's Alterations, as defined in Paragraph 12 below, or Tenant's
particular use of the Premises), including the Americans with Disabilities Act
of 1990 and any other laws relating to the accessibility or usability of the
Premises by disabled persons, and any and all laws relating to toxic or
hazardous substances or materials. Tenant shall not do or permit anything to be
done in the Premises or on or about the Real Property which will in any way
conflict with any law. Tenant shall immediately furnish Landlord with any
notices received or required by law to be given by Tenant from any insurance
company or governmental agency regarding any unsafe or unlawful conditions
within the Premises.

          11.  Personal Property and Other Taxes. Tenant shall pay, before
               ---------------------------------
delinquency, any and all taxes, fees and other governmental impositions levied
against Landlord or Tenant (a) upon Tenant's equipment, fixtures, improvements
and other personal property located in the Premises, or (b) by virtue of any
Alterations (as defined below) made by Tenant to the Premises. If any such fee,
charge or other imposition is paid by Landlord, Tenant shall reimburse Landlord
for Landlord's payment upon demand.

          12.  Alterations. Tenant shall not make or permit to be made any
               -----------
alterations or improvements to the Premises, including installation or
alteration of any telecommunications wiring or cabling in or about the Premises
("Alterations"), without the prior written approval of Landlord. All Alterations
shall be made at Tenant's sole cost. Alterations shall be performed by a general
contractor or other service provider designated by Landlord, with subcontractors
approved in advance by Landlord, which approval shall not be unreasonably
withheld, and shall be performed diligently and in a first-class workmanlike
manner and in accordance with plans and specifications reasonably approved by
Landlord. Tenant shall pay Landlord a fee equal to ten percent (10%) of the cost
of the Alterations for its management and supervision of the progress of the
work. Any Alterations, including moveable partitions that are affixed to the
Premises (but excluding moveable, free standing partitions) and all carpeting,
shall at once 

                                       7
<PAGE>
 
become part of the Building and the property of Landlord. Tenant shall give
Landlord not less than ten (10) days prior written notice of the date the
construction of the Alterations is to commence. Landlord may post and record an
appropriate notice of nonresponsibility with respect to any Alteration and
Tenant shall maintain any such notices posted by Landlord in or on the Premises.

          At Landlord's sole election, any or all Alterations made for or by
Tenant shall be removed from the Premises at the expiration or sooner
termination of this Lease, and the Premises shall be restored to their condition
prior to the making of the Alterations, ordinary wear and tear excepted. The
removal of the Alterations and the restoration of the Premises shall be
performed by a general contractor selected by Tenant and reasonably approved by
Landlord, in which event Tenant shall pay the general contractor's fees and
costs in connection with such work. Any separate work letter or other agreement
which is hereafter entered into between Landlord and Tenant pertaining to
Alterations shall be automatically governed by this Paragraph 12, unless
otherwise expressly stated in such work letter or agreement.

          13.  Repair. Subject to the provisions of this Paragraph 13, Tenant,
               ------
at Tenant's sole cost, shall keep the Premises in good condition and repair,
damage by fire, earthquake, act of God or the elements excepted. Tenant waives
all rights to make repairs at the expense of Landlord as provided by any law now
or hereafter in effect. Except as specifically set forth in this Lease, Landlord
has no obligation to alter, remodel, improve, repair, decorate or paint the
Premises or any part thereof. Tenant hereby waives the provisions of California
Civil Code Sections 1932(1), 1941 and 1942 and of any similar law, statute or
ordinance now or hereafter in effect.

          Landlord shall, at Landlord's sole cost, perform those repairs that
are necessitated because of fire, earthquake, act of God or the elements, or by
the negligence or willful misconduct of Landlord. Further, Landlord shall repair
and maintain in good condition the structural portions of the Building, the
exterior and the public and common areas of the Real Property and all Building
systems, including plumbing, HVAC, electrical, telecommunications cabling, life
safety and other systems installed or furnished by Landlord, but excluding (i)
non-Building standard lighting and electrical and telecommunications wiring and
(ii) extraordinary quantities of electrical, telecommunications, plumbing, HVAC
or other Building facilities or distribution thereof, the costs of all of which
shall be operating Expenses. Notwithstanding the foregoing, if the repairs
Landlord is required to make pursuant to this Paragraph are necessitated by the
negligence or deliberate misconduct of Tenant or Tenant's agents, employees or
contractors, then Tenant shall reimburse Landlord for the cost of such repair to
the extent Landlord is not reimbursed therefor by insurance. Landlord shall in
no event be obligated to repair any wear and tear to the Premises.

          14.  Assignment and Subletting. Tenant shall not, either voluntarily
               -------------------------
or by operation of law, assign, mortgage, pledge, encumber or otherwise transfer
all or any portion of 

                                       8
<PAGE>
 
Tenant's interest in this Lease (collectively, an "assignment") nor sublet all
or any portion of the Premises ("sublease") without Landlord's prior written
consent, which consent shall not be unreasonably withheld. Landlord's conditions
to such consent may include requiring that the assignee or subtenant (i) meets
Landlord's credit standards for tenants of the Building and (ii) will use the
Premises for operation of a business consistent with the use of the Building as
a first-class office building. For purposes hereof, a transfer of twenty-five
percent (25%) or more of the ownership interest in Tenant shall be deemed an
assignment.

          Prior to entering into an assignment or sublease, Tenant shall submit
to Landlord for Landlord's reasonable written approval, Tenant's proposed
sublease or assignment agreement (which shall name the proposed assignee or
subtenant), together with a current financial statement, credit references and
business plan of such proposed assignee or subtenant, and such other information
as Landlord may reasonably request. If Tenant enters into an assignment or
subletting without Landlord's prior written approval, or Tenant obtains such
approval but does not deliver to Landlord a copy of the fully executed
assignment or subletting document approved by Landlord, then, at Landlord's
option, such assignment or subletting shall be void and constitute an Event of
Default. Consent by Landlord to an assignment or subletting shall neither
relieve Tenant from the necessity of obtaining consent to any future assignment
or sublease nor release Tenant from any of its obligations under this Lease.

          Tenant shall reimburse Landlord for any and all reasonable costs
incurred by Landlord in processing a proposed assignment or sublease. In the
event of an assignment or sublease, Landlord shall be entitled to receive, as
Rent hereunder, any consideration (including payment for leasehold improvements
owned by Landlord) paid by the assignee or subtenant for the assignment or
sublease and, in the case of a sublease, the excess of the amount of Rent paid
for the sublet space by the subtenant over the total amount of Monthly Rent and
Additional Rent under Paragraph 3 and Paragraph 6 hereof. Upon Landlord's
request, Tenant shall assign to Landlord all amounts to be paid to Tenant by any
such subtenant and assignee and shall direct such subtenant or assignee to pay
the same directly to Landlord.

          15.  Indemnification. Landlord and the holders of any Superior
               ---------------
Interests (as defined in Paragraph 21 hereof) shall not be liable to Tenant and
Tenant hereby waives all claims against such parties for any loss, injury or
other damage to person or property in or about the Premises or the Real Property
from any cause whatsoever, including earth movement, gas, fire, oil, electricity
or leakage of any character from the roof, walls, basement or other portion of
the Premises or the Building, or acts of other tenants of the Building;
provided, however, that the foregoing waiver shall be inapplicable to any loss,
injury or damage resulting directly from Landlord's gross negligence or willful
misconduct.

          Tenant shall hold Landlord and the holders of any Superior Interest,
and the constituent owners thereof (hereinafter collectively called the
"Indemnities") harmless from and indemnify the Indemnitees against any claims,
liability, damages or expenses, including 

                                       9
<PAGE>
 
reasonable attorneys' fees and costs incurred in defending against the same, to
the extent arising from (a) the acts or omissions of Tenant, Tenant's employees,
agents, contractors, licensees, subtenants, customers, guests or invitees in or
about the Real Property, or (b) any breach or Event of Default under this Lease
by Tenant, or (c) any accident, injury or damage, to any person or property,
occurring in or about the Premises or the Real Property; except for such claims,
liability, damages or expenses to the extent they are caused solely and directly
by the negligence or willful acts or omissions of Landlord or its authorized
representatives. In case any action or proceeding be brought against any of the
Indemnitees by reason of any such claim or liability, Tenant, upon notice from
Landlord, covenants to resist and defend at Tenant's sole expense such action or
proceeding by counsel reasonably satisfactory to Landlord. The provisions of
this Paragraph 15 shall survive the termination of this Lease with respect to
any injury, illness, death or damage occurring prior to such termination.

          16.  Insurance.
               ---------

               (a)  Policies. At Tenant's expense, Tenant shall procure, carry
                    --------
and maintain in effect, in a form acceptable to Landlord and with such insurance
companies as are acceptable to Landlord, insurance coverage by the following
policies of insurance:

                    (i)   Liability insurance on an occurrence basis with limits
               in an amount not less than $3,000,000 Combined Single Limits per
               occurrence, and for claims or losses arising out of or resulting
               from personal injury (including bodily injury), death and
               property damage sustained or alleged to have been sustained by
               any person for any reason on the Premises, for liability arising
               out of or resulting from Tenant's covenant in Paragraph 15 to
               indemnify Landlord, its agents and employees, or for contractual
               liability;

                    (ii)  All Risk Replacement Cost insurance covering property
               of every description and kind owned by Tenant and located in the
               Premises and for Tenant's Alterations in an amount equal to 80%
               of the full replacement value thereof; and

                    (iii) Workers' compensation insurance, in accordance with
               law.

               (b)  Increase to Insurance Limits. Not more often than every one
                    ----------------------------
(1) year and upon not less than sixty (60) days prior written notice, Landlord,
in its reasonable discretion, may require Tenant to increase the insurance
limits set forth in Subparagraphs 16(a)(i) and 16(a)(ii), above.

               (c)  Named Insureds. All policies of liability insurance so
                    --------------
obtained and maintained shall name each of Landlord and Transamerica Real Estate
Management Co. as an additional insured, provide that the insurance so endorsed
will be the primary insurance 

                                       10
<PAGE>
 
providing coverage for Landlord, and contain a cross-liability endorsement
stating that the rights of named insureds shall not be prejudiced by one insured
making a claim or commencing an action against another named insured. At
Landlord's election, such policies shall name the holder of any mortgage or deed
of trust on the Real Property as an insured party under a standard mortgagee
endorsement.

               (d)  Landlord's Rights. All such policies shall further provide
                    -----------------
that no cancellation, reduction or modification of coverage will occur without
thirty (30) days prior written notice to Landlord and Transamerica Real Estate
Management Co. Tenant shall deliver certificates of all insurance required
hereunder upon the commencement of the Term of this Lease. In the event Tenant
does not comply with the requirements of this Paragraph 16, Landlord may, at its
option and at Tenant's expense, purchase such insurance coverage to protect
Landlord. The cost of such insurance shall be paid to Landlord by Tenant
immediately upon demand therefor.

          17.  Mutual Waiver of Subrogation. The parties release each other, and
               ----------------------------
their respective authorized representatives, from any claims for loss or damage
that are caused by or result from perils insured under any insurance policies
carried by the parties in force at the time of any such damage. Each party shall
cause each insurance policy obtained by it to provide that the insurer waives
all right of recovery by way of subrogation against either party in connection
with any loss or damage covered by the policy. Neither party shall be liable to
the other for any loss or damage caused by the insured risks under any insurance
policy required by this Lease.

          18.  Damage and Destruction. If all or a part of the Premises or the
               ----------------------
Building are damaged by fire or other casualty, and the damage can, in
Landlord's reasonable opinion, be repaired within sixty (60) days of the damage,
then Landlord shall repair the damage and this Lease shall remain in effect. If
the repairs cannot, in Landlord's reasonable opinion, be made within the sixty
(60)-day period, Landlord at its option exercised by written notice to Tenant
within the sixty (60)-day period, shall either (a) repair the damage, in which
event this Lease shall continue in full force and effect, or (b) terminate this
Lease as of the date specified by Landlord in the notice, which date shall be
not less than thirty (30) days nor more than sixty (60) days after the date such
notice is given, and this Lease shall terminate on the date specified in the
notice.

          If the fire or other casualty damages the Premises or the common areas
of the Building necessary for Tenant's use and occupancy of the Premises, and
the damage does not result from the negligence or willful misconduct of Tenant
or Tenant's agents, employees, contractors, licensees or invitees, then during
the period the Premises or any part thereof are rendered unusable by such damage
and repair, Tenant's Monthly Rent and Additional Rent under Paragraph 3 and
Paragraph 6 hereof shall be proportionately reduced based upon the extent to
which the damage and repair prevents Tenant from conducting its business at the
Premises. Landlord shall not be obligated to repair or replace any of Tenant's
movable furniture, 

                                       11
<PAGE>
 
equipment, trade fixtures and other personal property, nor any Alterations
installed in the Premises by Tenant. A total destruction of the Building shall
automatically terminate this Lease. Tenant hereby waives California Civil Code
Sections 1932(2) and 1933(4), providing for termination of hiring upon
destruction of the thing hired, and Sections 1941 and 1942, providing for
repairs to and of premises.

          19.  Eminent Domain. If all or any part of the Premises is taken by
               --------------
any entity by exercise of the power of eminent domain, this Lease shall
terminate as of the date of such taking. This Lease shall not terminate upon a
temporary taking of the Premises, but Tenant's Monthly Rent and Additional Rent
hereunder shall abate during the period of the taking. Landlord shall be
entitled to all awards and to all purchase money attributable to the Premises or
the unexpired Term of this Lease, except for any part of the award attributable
to Tenant's removable personal property or relocation expenses, which part shall
be payable to Tenant. Landlord and Tenant waive the provisions of California
Code of Civil Procedure Section 1265.130 and any other applicable existing or
future law that allows a party to petition the courts for termination of this
Lease for a partial taking of the Premises.

          20.  Estoppel Certificates. Upon not less than ten (10) days' prior
               ---------------------
notice from Landlord, Tenant shall execute, acknowledge and deliver to Landlord
a statement setting forth and certifying such matters as may be reasonably
requested (e.g., Term of this Lease, Monthly Rent, Additional Rent, Security
Deposit paid, defaults and similar matters). Any such statement given by Tenant
may be conclusively relied upon by a prospective purchaser of the Building or by
a lender obtaining a lien on the Real Property as security.

          21.  Subordination. This Lease is expressly made subject and
               -------------
subordinate to any mortgage, deed of trust, ground lease, underlying lease or
like encumbrance affecting any part of the Building or any interest of Landlord
therein which is now existing or hereafter executed or recorded (any of the
foregoing being a "Superior Interest") without the necessity of any further
documentation evidencing such subordination. Notwithstanding the foregoing,
Tenant shall, upon Landlord's request, execute and deliver to Landlord a
document evidencing the subordination of this Lease to a particular Superior
Interest. If the holder of any Superior Interest should foreclose, judicially or
non-judicially, on its mortgage or deed of trust or, with respect to a ground or
underlying lease, the ground or underlying lease should terminate, then Tenant
shall automatically attorn to and recognize such holder or its assignee,
designee or successor in interest (a "Successor") as the landlord under the
Lease and be in privity of estate and contract with such Successor so long as
such Successor agrees not to disturb Tenant's right of possession under the
Lease except as provided for in the Lease.

          22.  Mortgage Protection. Tenant agrees to give the holder of any
               -------------------
mortgage or deed of trust on the Building ("lender"), by registered or certified
mail, a copy of any notice of default served by Tenant on Landlord, provided
that Tenant has previously been notified in writing of the name and address of
the lender. If Landlord fails to cure the default within thirty 

                                       12
<PAGE>
 
(30) days from the date of Tenant's notice of default, then the lender will have
an additional thirty (30) days to cure the default or if the default cannot
reasonably be cured within that time, then such additional time as may be
reasonably necessary to cure the default, and this Lease will not be terminated
so long as the lender is diligently endeavoring to cure the default.

          23.  Liens. If any mechanic's, materialman's or other liens arising
               -----
out of work performed at the Premises by or on behalf of Tenant is filed against
the Building or Tenant's interest in the Premises, then Tenant shall immediately
upon its notice or actual knowledge of such lien, remove the same of record, by
bonding or otherwise. Landlord shall have the right to post and keep posted on
the Premises any notices which it deems necessary for protection from such
liens. If any such lien is filed and not removed pursuant to the above, Landlord
may, after ten (10) days' written notice to Tenant, without waiving its rights
based on such breach by Tenant, pay and satisfy the same, and in such event the
sums so paid by Landlord shall be due and payable by Tenant immediately upon
demand, with interest at the Interest Rate from the date paid by Landlord
through the date Tenant pays Landlord. Any filing or recordation of this Lease
or any short form or memorandum thereof without the prior written consent of
Landlord shall be deemed a "lien" for purposed of this Paragraph.

          24.  Entry By Landlord. Landlord may, upon reasonable advance notice
               -----------------
(provided that no advance notice need be given if an emergency necessitates an
immediate entry or prior to entry to provide routine janitorial services), enter
the Premises to (a) inspect the same and determine whether Tenant is in
compliance with its obligations hereunder, (b) supply janitorial and any other
service to be provided by Landlord hereunder, (c) show the Premises to
prospective purchasers, mortgagees or tenants, (d) post notices of
nonresponsibility and (e) perform any installation, repair or maintenance
required or permitted to be performed by Landlord. Tenant shall not be entitled
to an abatement of rent, nor shall Landlord be liable to Tenant for any
inconvenience or loss of business resulting from such entry.

          25.  Abandonment. Tenant shall not vacate or abandon the Premises at
               -----------
any time during the Term hereof. If Tenant abandons, vacates or surrenders all
or any part of the Premises or is dispossessed of the Premises by process of
law, or otherwise, any movable furniture, equipment, trade fixtures, or other
personal property belonging to Tenant and left on the Premises shall at the
option of Landlord be deemed to be abandoned and, whether or not the property is
deemed abandoned, Landlord shall have the right to remove such property from the
Premises and charge Tenant for the removal and any restoration of the Premises
as provided in Paragraph 12. Landlord may charge Tenant for the storage of
Tenant's property left on the Premises at such rates as Landlord may from time
to time reasonably determine, or, Landlord may, at its option, store Tenant's
property in a public warehouse at Tenant's expense. Neither the foregoing nor
any other provision of this Lease shall impose upon Landlord any obligation to
care for or preserve any of Tenant's property left upon the Premises, and Tenant
hereby waives and releases Landlord from any claim or liability in connection
with the removal of such 

                                       13
<PAGE>
 
property from the Premises and the storage thereof and specifically waives the
provisions of California Civil Code Section 1542 with respect to such release.

          26.  Default.
               -------

               (a)  Events of Default. The occurrence of any of the following
                    -----------------
shall constitute an "Event of Default" by Tenant:

                    (i)   Tenant fails to pay within ten (10) days of the date
               due Rent hereunder.

                    (ii)  Abandonment of the Premises by Tenant for ten (10)
               consecutive days.

                    (iii) The making by Tenant of any general assignment for the
               benefit of creditors; the filing by or against Tenant of a
               petition to have Tenant adjudged an insolvent or a bankrupt or of
               a petition seeking reorganization, arrangement, composition,
               readjustment, liquidation, dissolution or similar arrangement
               under any bankruptcy law (unless in the case of a petition filed
               against Tenant, the same is dismissed within sixty (60) days);
               the appointment of a trustee or receiver to take possession of
               substantially all of Tenant's assets or of Tenant's interest in
               this Lease where such seizure is not discharged within thirty
               (30) days.

                    (iv)  Tenant fails to perform any other provision of this
               Lease within thirty (30) days of the date required for such
               performance (or if the noncompliance cannot by its nature be
               cured within the 30-day period, if Tenant fails to commence to
               cure such noncompliance within the 30-day period and thereafter
               diligently prosecute such cure to completion).

               (b)  Remedies. Upon the occurrence of an Event of Default,
                    --------
Landlord shall have the following remedies, which shall be cumulative and shall
be in addition to any other remedies allowed by law:

                    (i)   Landlord may terminate Tenant's right to possession of
               the Premises at any time by written notice to Tenant. Tenant
               expressly acknowledges that in the absence of such written notice
               from Landlord, no other act of Landlord, including its re-entry
               into the Premises, its efforts to relet the Premises, its
               reletting of the Premises for Tenant's account, its storage, of
               Tenant's personal property and trade fixtures, its acceptance of
               keys to the Premises from Tenant or its exercise of any other
               rights and remedies under this Paragraph 26, shall constitute an
               acceptance of Tenant's surrender of the Premises or constitute a
               termination of this 

                                       14
<PAGE>
 
               Lease or of Tenant's right to possession of the Premises.

                          Upon such termination in writing of Tenant's right to
               possession of the Premises, this Lease shall terminate and
               Landlord shall be entitled to recover damages from Tenant as
               provided in California Civil Code Section 1951.2 or any other
               applicable existing or future law providing for recovery of
               damages for such breach, including the following:

                          (1) The reasonable cost of recovering the Premises;
                    plus

                          (2) The reasonable cost of removing Tenant's
                    Alterations, trade fixtures and improvements; plus

                          (3) All unpaid Rent due or earned hereunder prior to
                    the date of termination, less the proceeds of any reletting
                    or any rental received from subtenants prior to the date of
                    termination applied as provided in Paragraph 26(b)(ii)
                    below, together with interest at the Interest Rate on such
                    sums from the date such Rent is due and payable until the
                    date of the reward of damages; plus

                          (4) The amount by which the Rent which would be
                    payable by Tenant hereunder, as reasonably estimated by
                    Landlord, from the date of termination until the date of the
                    award of damages, exceeds the amount of such rental loss as
                    Tenant proves could have been reasonably avoided together
                    with interest at the Interest Rate on such sums from the
                    date such rent is due and payable until the date of the
                    award of damages; plus

                          (5) The amount by which the Rent which would be
                    payable by Tenant hereunder, as reasonably estimated by
                    Landlord, for the remainder of the then Term, after the date
                    of the award of damages exceeds the amount such rental loss
                    as Tenant proves could have been reasonably avoided,
                    discounted at the discount rate published by the Federal
                    Reserve Bank of San Francisco for member banks at the time
                    of the award plus one percent (1%); plus

                          (6) Such other amounts in addition to or in lieu of
                    the foregoing as may be permitted from time to time by
                    applicable law.

                    (ii)  Landlord may continue this Lease in full force and 
                    effect 

                                       15
<PAGE>
 
               and may enforce all of its rights under this Lease, including the
               right to recover Rent as it becomes due. During the continuance
               of an Event of Default, Landlord may enter the Premises without
               terminating this Lease and sublet all or any part of the Premises
               for Tenant's account to any person, for such term (which may be a
               period beyond the remaining Term of this Lease), at such rents
               and on such other terms and conditions as Landlord deems
               advisable. In the event of any such subletting, rents received by
               Landlord from such subletting shall be applied (i) first, to the
               payment of the costs of maintaining, altering and preparing the
               Premises for subletting, the other costs of subletting, including
               brokers, commissions, attorneys' fees and expenses of removal of
               Tenant's personal property, trade fixtures and Alterations; (ii)
               second, to the payment of Rent then due and payable hereunder;
               (iii) third, to the payment of future Rent as the same may become
               due and payable hereunder; (iv) fourth, the balance, if any,
               shall be paid to Tenant upon (but not before) expiration of the
               Term of this Lease. If the rents received by Landlord from such
               subletting, after application as provided above, are insufficient
               in any month to pay the Rent due and payable hereunder for such
               month, Tenant shall pay such deficiency to Landlord monthly upon
               demand. Notwithstanding any such subletting for Tenant's account
               without termination, Landlord may at any time thereafter, by
               written notice to Tenant, elect to terminate this Lease by virtue
               of a previous Event of Default.

                          During the continuance of an Event of Default, for so
               long as Landlord does not terminate Tenant's right to possession
               of the Premises, Landlord shall not unreasonably withhold its
               consent to an assignment or sublease of Tenant's interest in the
               Premises or in this Lease.

                    (iii) During the continuance of an Event of Default,
               Landlord may enter the Premises without terminating this Lease
               and remove all Tenant's personal property, Alterations and trade
               fixtures from the Premises and store them at Tenant's risk and
               expense or dispose of them upon compliance by Landlord with
               applicable California law.

                    (iv)  Landlord may require Tenant to remove any and all
               Alterations from the Premises or, if Tenant fails to do so within
               ten (10) days after Landlord's request, Landlord may do so at
               Tenant's expense.

                    (v)   Landlord may cure the Event of Default at Tenant's
               expense. If Landlord pays any sum or incurs any expense in curing
               the 

                                       16
<PAGE>
 
               Event of Default, Tenant shall reimburse Landlord upon demand for
               the amount of such payment or expense with interest at the
               Interest Rate from the date the sum is paid or the expense is
               incurred until Landlord is reimbursed by Tenant. Any amount due
               Landlord under this subsection shall constitute Rent hereunder.

          27.  Surrender; Holding Over.
               -----------------------

               (a)  Surrender. Upon the expiration or other termination of this
                    ---------
Lease, Tenant shall surrender the Premises and all improvements and Alterations
to Landlord broom-clean and in their original condition, except for reasonable
wear and tear. At such time, Tenant shall remove from the Premises all of
Tenant's personal property, trade fixtures and Alterations that Tenant is
required by Landlord to remove under the provisions of this Lease. If such
removal is not completed at the expiration or other termination of this Lease,
Landlord may remove the same at Tenant's expense. Any damage to the Premises or
the Building caused by such removal shall be repaired promptly by Tenant or, if
Tenant fails to do so, Landlord may do so at Tenant's expense. The removal of
Alterations from the Premises shall be governed by Paragraph 12 hereof. Tenant's
obligations under this Paragraph shall survive the expiration or other
termination of this Lease.

               (b)  Holding Over. If Tenant remains in possession of the
                    ------------
Premises after the expiration of this Lease, Tenant's occupancy shall be a 
month-to-month tenancy at a Monthly Rent equal to one hundred fifty percent
(150%) of the Monthly Rent in effect during the month immediately preceding the
expiration of the Lease plus the applicable Additional Rent. Except as provided
in the preceding sentence, the month-to-month tenancy shall be on the terms and
conditions of this Lease. Landlord's acceptance of rent after such holding over
with Landlord's written consent shall not result in any other tenancy or in a
renewal of the original Term hereof.

          28.  Waiver. No provision of this Lease shall be deemed waived
               ------
by Landlord unless such waiver is in writing and signed by Landlord. The waiver
by Landlord of any breach of any provision of this Lease shall not be deemed a
waiver of any subsequent breach of the same or any other provision of this
Lease. Landlord's acceptance of any payments of Rent due under this Lease shall
not be deemed a waiver of any default by Tenant under this Lease (including
Tenant's recurrent failure to timely pay Rent) other than Tenant's nonpayment of
the accepted sums, and no endorsement or statement on any check or accompanying
any check or payment shall be deemed an accord and satisfaction. Landlord's
consent to or approval of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waive or render unnecessary Landlord's consent
to or approval of any subsequent act by Tenant.

          29.  Attorneys' Fees. In any action or proceeding between Landlord and
               ---------------
Tenant (including an action or proceeding between Landlord and the trustee or
debtor in possession while Tenant is a debtor in a proceeding under any
bankruptcy law) to enforce any 

                                       17
<PAGE>
 
provision of this Lease, the losing party shall pay to the prevailing party all
costs and expenses, including reasonable attorneys' fees and expenses, incurred
in such action and in any appeal in connection therewith by such prevailing
party. The "prevailing party" will be determined by the court before whom the
action was brought based upon an assessment of which party's major arguments or
positions taken in the suit or proceeding could fairly be said to have prevailed
over the other party's major arguments or positions on major disputed issues in
the court's decision.

          30.  Time and Applicable Law. Time is of the essence of each provision
               -----------------------
of this Lease. This Lease shall be governed by California law.

          31.  Successors. Subject to the provisions of this Lease, the
               ----------
covenants and conditions hereunder shall be binding upon and inure to the
benefit of the heirs, successors, executors and administrators of the parties
hereto.

          32.  Notices. All notices and demands given by either party to
               -------
the other hereunder shall be in writing and shall be delivered personally, or by
overnight receipted courier or by United States mail, postage prepaid,
registered or certified mail, return receipt requested, addressed to Tenant or
Landlord, as the case may be, at their respective addresses for notices set
forth in the Summary, or such other address as they may from time to time
designate by notice hereunder. Each notice shall be deemed received on the date
of the personal service or three (3) days after the mailing thereof.

          33.  Severability. The invalidity or unenforceability of any one or
               ------------
more provisions of this Lease shall in no way affect any other provision.

          34.  No Offer. Submission of this document for examination and
               --------
signature by Tenant does not constitute a reservation of or option to lease, and
this document is not effective until executed and delivered by both Landlord and
Tenant.

          35.  Directory Board. Landlord shall list Tenant's name on the
               ---------------
directory board in the lobby of the Building at Landlord's cost; provided,
however, any change to the initial listing and any additional listings shall be
at Tenant's cost and expense. Landlord's acceptance of any name for listing on
the directory board shall in no event be, or be deemed to be, nor will it
substitute for, Landlord's consent, required by this Lease, to any sublease,
assignment or other occupancy of the Premises.

          36.  Real Estate Brokers. Landlord and Tenant each represent and
               -------------------
warrant to the other that such party has negotiated this Lease only with the
Real Estate Broker(s), if any, identified in Paragraph 14 of the Summary and has
not authorized or employed any other real estate broker or salesperson to act
for such party in connection with this Lease. Each party shall hold the other
harmless from and indemnify and defend the other against any and all claims by
any real estate broker or salesperson other than the Real Estate Broker(s), if
any, identified in the 

                                       18
<PAGE>
 
Summary for a commission, finder's fee or other compensation as a result of the
inaccuracy of such party's representation above.

          37.  Interpretation. Whenever the context requires, all words used in
               --------------
the singular will be construed to have been used in the plural, and vice versa,
and each gender will include any other gender. The word "include(s)" means
"include(s), without limitation," and the word "including" means "including, but
not limited to."

          38.  Rules and Regulations. Tenant shall comply with the Rules and
               ---------------------
Regulations set forth on Exhibit C, as such Rules and Regulations may be
                         ---------
modified from time to time.

          39.  Limitation of Landlord's Liability. Any liability of Landlord
               ----------------------------------
(including Landlord's partners, shareholders, affiliates, agents and employees)
under this Lease shall be limited to the equity interest of Landlord in the
Real Property, and Tenant agrees to look solely to such interest for the
recovery of any judgment, it being intended that Landlord shall not be
personally liable for any deficiency or judgment.

          40.  Entire Agreement. This Lease (which includes the Exhibits and
               ----------------
Addenda attached hereto) constitutes the entire agreement between Landlord and
Tenant with respect to Tenant's lease of the Premises and supersedes any
previous agreements of the parties with regard thereto. Notwithstanding anything
contained in the Lease, there are no oral agreements between Landlord and Tenant
affecting this Lease. There are no representations between Landlord and Tenant
other than those contained in this Lease and all reliance with respect to any
representation is solely upon the representations contained in this Lease.

          41.  No Merger. The voluntary or other surrender of this Lease by
               ---------
Tenant, or mutual cancellation thereof, shall not work a merger, and shall, at
the option of Landlord, terminate all or any existing subleases or subtenancies,
or may, at the option of Landlord, operate as an assignment to Landlord of any
or all such subleases or tenancies.

          42.  Changes to Building or Common Area. The description of the
               ----------------------------------
premises and the location of any duct work and plumbing within the Premises
shall be subject to such changes as Landlord determines to be necessary or
desirable in the course of the construction of the same, and no such changes
shall invalidate or affect this Lease. Landlord shall have the right at any
time, and from time to time during the term of the Lease, to change the
arrangement, character, use or locations of entrances or passageways, doors and
doorways, corridors, elevators, stairs, landscaping, toilets, or any other parts
of the Building, to change common area to rental space and rental space to
common area, and to change the name, number or designation by which the Building
is commonly known, and none of the foregoing shall be deemed an actual or
constructive eviction of Tenant nor shall entitle Tenant to any reduction of the
rent hereunder or nor shall result in any liability of Landlord to Tenant. Any
diminution or shutting off of the 

                                       19
<PAGE>
 
light, air or view by any structure which may be erected on land adjacent to the
Building shall in no way affect this Lease or impose any liability on Landlord.

          43.  No Partnership. It is expressly understood that Landlord does not
               --------------
in any way or for any purpose become a partner of Tenant in the conduct of
Tenant's business, or otherwise, or joint venturer or member of a joint
enterprise with Tenant.

          44.  Exhibits. The exhibits and addenda, if any, attached to the Lease
               --------
are incorporated herein by this reference and made a part hereof as if fully set
forth herein.

          45.  Lease Summary. At such time as all the Lease terms called for in
               -------------
the Summary attached hereto have been finally determined in accordance with the
provisions of this Lease, the Summary shall be completed and signed by the
parties and shall thereafter be a final and binding agreement of the parties as
to the terms and conditions set forth therein.

          46.  Right to Terminate. Landlord shall have the right to terminate
               ------------------
this Lease at any time provided that all of the following conditions are met:
(i) the purpose of such termination is because Landlord has elected to demolish
the Building, (ii) Landlord has provided Tenant with at least six months' prior
written notice of its intent to terminate the Lease, with the effective date of
such termination either set forth in the notice or with a provision that
Landlord shall provide Tenant with at least sixty (60) days prior written
notice of the effective date of termination, and (iii) Landlord has terminated
or expects to terminate all other leases for space in the Building.

          This Lease is executed by Landlord and Tenant as of the date set
forth above.

                                   EXHIBIT B

          Landlord shall, at its sole cost and expense, furnish and install the
Premises with building standard tenant improvements, utilizing building standard
finishes and materials. Within ten (10) days after the date of this Lease,
Landlord and Tenant shall agree on a space plan and working drawings (the
"Plans") for the design, layout and construction of Tenant's tenant improvements
(the "Tenant Improvements"). Landlord shall pay for the cost of preparing the
space plan and working drawings. Landlord and Tenant agree to work diligently
and in good faith to complete the Plans within this ten (10) day period.

          Once the Plans have been approved in writing by both Landlord and
Tenant, Landlord shall proceed to cause the Tenant Improvements to be built,
using Landlord's general contractor. Landlord shall exercise diligent and
commercially reasonable efforts to cause the build out of the Tenant
Improvements to be undertaken and completed in a prompt manner, subject to force
majeure. Landlord shall provide Tenant with a tenant improvement allowance of
Twenty Thousand Six Hundred Dollars ($20,600) (the "TI Allowance"), to be
applied by Landlord against the cost of constructing the Tenant Improvements as
such Tenant Improvements are being constructed. When the Tenant Improvements are
completed, Landlord shall provide Tenant with a written statement of the total
actual cost of constructing the Tenant Improvements.

          If the actual cost of constructing the Tenant Improvements exceeds
$20,600, then Tenant shall reimburse Landlord for the amount of such excess.
Tenant shall reimburse Landlord for such excess within ten (10) days after
receipt of a bill therefor from Landlord and such excess amount shall constitute
Rent under the Lease.

          If the actual cost of constructing the Tenant Improvements is less
than $20,600, then Tenant shall be entitled to a credit against Monthly Rent
owing under the Lease in an amount equal to the difference between $20,600 and
the actual cost of constructing the Tenant Improvements; provided, however, that
in no event shall the credit exceed Eight Thousand Four Hundred Eleven and
66/100 Dollars ($8,411.66). Tenant may avail itself of this credit by providing
written notice to Landlord of its desire to use the credit, whereupon Landlord
shall apply the credit against the Monthly Rent next owing until the credit is
fully applied. The credit must be applied by Tenant against the Monthly Rent
owing during the first six months of the Lease term. If Tenant fails to provide
written notice to Landlord of its desire to apply the credit during this six
month period, then the credit shall be forfeited. If Tenant provides written
notice to Landlord of its desire to apply the credit at a date such that the
entire credit will not be fully applied against Monthly Rent owing during the
first six months of the Lease term, then any credit that is not applied by the
end of this six month period shall be forfeited.

Sansome Street (the "Building") as thermal pipe insulation throughout the
building; boiler insulation in the basement boiler room; 9" x 9" and 12" x 12"
vinyl asbestos floor tile; joint compounds on partitions; and in roof tar and
felt. Also, the cores of fire-rated doors and all vinyl floor tile in the
Building should be treated as containing ACM until you are notified to the
contrary.

          UNDER THE ASBESTOS MANAGEMENT PLAN, EACH TENANT IN THE BUILDING, OR
ANY PERSON (INCLUDING A CONTRACTOR) ACTING ON A TENANT'S BEHALF, IS REQUIRED:

          1.   To obtain WRITTEN PERMISSION from Building Management's asbestos
site manager ("Site Manager") before the tenant, or any person acting on such
tenant's behalf, performs ANY construction, renovation, maintenance, repair,
alteration, addition, modification, improvement or like work or to the premises
leased.

          2.   To obtain a WORK PERMIT from the Site Manager before the tenant,
or any person acting on such tenant's behalf, engages in (a) any work requiring
the moving or disturbance of thermal pipe insulation throughout the building or
boiler insulation in the basement boiler room, (b) any work which will penetrate
the sheetrock on exterior walls, demising walls or columns or roof tar and felt,
(c) any work on Building floors that involves disturbance of floor tiles or
penetration of the floor slab, (d) any other work which could disturb ACM in the
Building, or (e) such other work as the Site Manager may designate from time to
time. The work permit shall serve as that written permission required by
paragraph 1, but only for work requiring a work permit.

          3.   To request permission from the Site Manager to do the work, and
to describe the scope of the work and the name of the contractor(s), if any, who
will perform the work. The Site Manager shall then determine, based upon the
nature and scope of the work described by the tenant, or a person acting on such
tenant's behalf, whether the work requires a work permit. In the case of all
work requiring a work permit, the Site Manager shall also determine whether such
work also requires the use of the Noncontainment or Containment Procedures
prepared by Building Management and shall determine whether it is appropriate
for the tenant or the tenant's contractor(s) to perform the work.

          4.   To strictly comply with all work permit requirements and
procedures supplied by the Site Manager as well as all directions given by the
Site Manager.

          5.   To immediately report to the Site Manager any and all spills or
other releases of ACM (including the presence of any debris which may contain
asbestos) which the 

                                       28
<PAGE>
 
tenant, or any person acting on such tenant's behalf, observes or suspects, so
that Building Management can respond as appropriate.

          Under no circumstances, shall any tenant, or any person acting on such
tenant's behalf, engage in work involving the disturbance (in any fashion) of
any wall or floor in the leased premises, including the removal of any item or
fixture from any wall or floor in the leased premises, until and unless written
permission is obtained from the Site Manager.

          No tenant, or any person acting on a tenant's behalf, shall touch or
disturb the ACM in the Building, including any debris suspected of containing
asbestos, except as specifically authorized in writing by the Site Manager on a
case-by-case basis.

     6.2  COMPLIANCE WITH LAW.

          (a)  Lessor warrants to Lessee that the Premises, in its state
existing on the date that the Lease term commences, but without regard to the
use for which Lessee will use the 


                                       2
<PAGE>
 
Premises, does not violate any covenants or restrictions of record, or any
applicable building code, regulation or ordinance in effect on such Lease term
commencement date. In the event it is determined that this warranty has been
violated, then it shall be the obligation of the Lessor, after written notice
from Lessee, to promptly, at Lessor's sole cost and expense, rectify any such
violation. In the event Lessee does not give to Lessor written notice of the
violation of this warranty within six months from the date that the Lease term
commences, the correction of same shall be the obligation of the Lessee at
Lessee's sole cost. The warranty contained in this paragraph 6.2(a) shall be of
no force or effect if, prior to the date of this Lease, Lessee was the owner or
occupant of the Premises, and, in such event, Lessee shall correct any such
violation at Lessee's sole cost.

          (b)  Except as provided in paragraph 6.2(a), Lessee shall, at Lessee's
expense, comply promptly with all applicable statutes, ordinances, rules,
regulations, orders, covenants and restrictions of record, and requirements in
effect during the term or any part of the term hereof, regulating the use by
Lessee of the Premises.  Lessee shall not use nor permit the use of the Premises

more than one tenant in the building containing the Premises, shall tend to
disturb such other tenants.

     6.3  CONDITION OF PREMISES.

          (a)  Lessor shall deliver the Premises to Lessee clean and free of
debris on Lease commencement date (unless Lessee is already in possession) and
Lessor further warrants to Lessee that the plumbing, lighting, air conditioning,
heating, and loading doors in the Premises shall be in good operating condition
on the Lease commencement date.  In the event that it is determined that this
warranty has been violated, then it shall be the obligation of Lessor, after
receipt of written notice from Lessee setting forth with specificity the nature
of the violation, to promptly, at Lessor's sole cost, rectify such violation.
Lessee's failure to give such written notice to Lessor within thirty (30) days
after the Lease commencement date shall cause the conclusive presumption that
Lessor has complied with all of Lessor's obligations hereunder.  The warranty
contained in this paragraph 6.3(a) shall be of no force or effect if prior to
the date of this Lease, Lessee was the owner or occupant of the Premises.

          (b)  Except as otherwise provided in this Lease, Lessee hereby accepts
the Premises in their condition existing as of the Lease commencement date or
the date that Lessee takes possession of the Premises, whichever is earlier,
subject to all applicable zoning, municipal, county and state laws, ordinances
and regulations governing and regulating the use of the Premises, and any
covenants or restrictions of record, and accepts this Lease subject thereto and
to all matters disclosed thereby and by any exhibits attached hereto.  Lessee
acknowledges that neither Lessor nor Lessor's agent has made any representation
or warranty as to the present or future suitability of the Premises for the
conduct of Lessee's business.

exterior walls and the exterior roof of the Premises. Lessor shall not, however,

shall have no obligation to make repairs under this Paragraph 7.1 until a
reasonable time after receipt of written notice of the need for such repairs.

Premises in good order, condition and repair.

interior walls and interior surface of exterior walls, ceilings, windows, doors,
plate glass, and skylights, located within the Premises, and all landscaping
driveways, parking lots, fences and signs located in the Premises and all
sidewalks and parkways adjacent to the Premises.  Lessee expressly waives the
benefit of any statute now or hereinafter in effect which would otherwise afford
Lessee the right to make repairs at Lessor's expense or to terminate this Lease
because of Lessor's failure to keep the Premises in good order, condition and
repair.

          (b)  If Lessee fails to perform Lessee's obligations under this
Paragraph 7.2 or under any other paragraph of this Lease, Lessor may at Lessor's
option enter upon the Premises after 10 days prior written notice to Lessee
(except in the case of emergency, in which case no notice shall be required),
perform such obligations on Lessee's behalf and put the Premises in good order,
condition and repair, and the cost thereof together with interest thereon at the
maximum rate than allowable by law shall be due and payable as additional rent
to Lessor together with Lessee's next rental installment.

          (c)  On the last day of the term hereof, or on any sooner termination,
Lessee shall surrender the Premises to Lessor in the same condition as received,
ordinary wear and tear excepted, clean and free of debris.  Lessee shall repair
any damage to the Premises occasioned by the installation or removal of its
trade fixtures, furnishing s and equipment.  Notwithstanding anything to the
contrary otherwise stated in this Lease,  Lessee shall leave the air lines,
power panels, electrical distribution systems, lighting fixtures, space heaters,
air conditioning, plumbing and fencing on the premises in good operating
condition.

     7.3. ALTERATIONS AND ADDITIONS.

          (a)  Lessee shall not, without Lessor's prior written consent make any
alterations, improvements, additions, or Utility Installations in, on or about
the Premises, except for nonstructural alterations not exceeding $2,500 in
cumulative costs during the term of this 


                                       4
<PAGE>
 
Lease. In any event, whether or not in excess of $2,500 in cumulative cost,
Lessee shall make no change or alterationto the exterior of the Premises nor the
exterior of the building(s) on the Premises without Lessor's prior written
consent. As used in this Paragraph 7.3 the term "Utility Installation" shall
mean carpeting, window coverings, air lines, power panels, electrical
distribution systems, lighting fixtures, space heaters, air conditioning,
plumbing, and fencing. Lessor may require that Lessee remove any or all of said
alterations, improvements, additions or Utility Installations at the expiration
of the term, and restore the Premises to their prior condition. Lessor may
require Lessee to provide Lessor, at Lessee's sole cost and expense, a lien and
completion bond in an amount equal to one and one-half times the estimated cost
of such improvements, to insure Lessor against any liability for mechanic's and
materialmen's liens and to insure completion of the work. Should Lessee make any
alterations, improvements, additions or Utility Installations without the prior
approval of Lessor, Lessor may require that Lessee remove any or all of the
same.

          (b)  Any alterations, improvements, additions or Utility Installations
in, or about the Premises that Lessee shall desire to make and which requires
the consent of the Lessor shall be presented to Lessor in written form, with
proposed detailed plans.  If Lessor shall give its consent, the consent shall be
deemed conditioned upon Lessee acquiring a permit to do so from appropriate
governmental agencies, the furnishing of a copy thereof to Lessor prior to the
commencement of the work and the compliance by Lessee of all conditions of said
permit in a prompt and expeditious manner.

          (c)  Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanics' or
materialmen's lien against the Premises or any interest therein.  Lessee shall
give Lessor not less than ten (10) days' notice prior to the commencement of any
work in the Premises, and Lessor shall have the right to post notices of non-
responsibility in or on the Premises as provided by Law.  If Lessee shall, in
good faith, contest the validity of any such lien, claim or demand, then Lessee
shall, at its sole expense defend itself and Lessor against the same and shall
pay and satisfy any such adverse judgment that may be rendered thereon before
the enforcement thereof against the Lessor or the Premises, upon the condition
that if Lessor shall require,  Lessee shall furnish to Lessor a surely bond
satisfactory to Lessor in an amount equal to such contested lien claim or demand
indemnifying Lessor against liability for the same and holding the Premises free
from the effect of such lien or claim.  In addition, Lessor may require Lessee
to pay Lessor's attorneys fees and costs in participating in such action if
Lessor shall decide it is to its best interest to do so.

          (d)  Unless Lessor requires their removal, as set forth in Paragraph
7.3(a), all alterations, improvements, additions and Utility Installations
(whether or not such Utility Installations constitute trade fixtures of Lessee),
which may be made on the Premises, shall become the property of Lessor and
remain upon and be surrendered with the Premises at the expiration of the term.
Notwithstanding the provisions of this Paragraph 7.3(d), Lessee's machinery and
equipment, other than that which is affixed to the Premises so that it cannot be
removed without material damage to the Premises, shall remain the property of
Lessee and may be removed by Lessee subject to the provisions of Paragraph
7.2(c).

8.   ASSURANCE; INDEMNITY.

     8.1  LIABILITY INSURANCE - LESSEE.  Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease a policy of Combined
Single Limit Bodily Injury and Property Damage Insurance insuring Lessee and
Lessor against any liability arising out of the use, occupancy or maintenance of
the Premises and all other areas appurtenant thereto.  Such insurance shall be
in an amount not less than $1,000,000 per occurrence.  The policy shall insure
performance by Lessee of the indemnity provisions of this Paragraph 8.  The
limits of said insurance shall not, however, limit the liability of Lessee
hereunder.

     8.2  LIABILITY INSURANCE - LESSOR.  Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury
and Property Damage Insurance, insuring Lessor, but not Lessee, against any
liability arising out of the ownership, use, occupancy or maintenance of the
Premises and all areas appurtenant thereto in an amount not less than $1,000,000
per occurrence.

     8.3  PROPERTY INSURANCE.  Lessor shall obtain and keep in force during the
term of this Lease a policy or policies of insurance covering loss or damage to
the Premises, but not Lessee's fixtures, equipment or tenant improvements in an
amount not to exceed the full replacement value thereof, as the same may exist
from time to time, providing protection against all perils included within the
classification of fire, extended coverage, vandalism, malicious mischief, flood
(in the event same is required by a lender having a lien on the Premises)
special extended perils ("all risk", as such term is used in the insurance
industry) but not plate glass insurance.  In addition, the Lessor shall obtain
and keep in force, during the term of this Lease, a policy of rental value
insurance covering a period of one year, with loss payable to Lessor, which
insurance shall also cover all real estate taxes and insurance costs for said
period.

     8.4  PAYMENT OF PREMIUM INCREASE.

          (a)  Lessee shall pay to Lessor, during the term hereof, in addition
to the rent, the amount of any increase in premiums for the insurance required
under Paragraphs 8.2 and 8.3 over and above such premiums paid during the Base
Period, as hereinafter defined, whether such premium increase shall be the
result of the nature of Lessee's occupancy, any act or omission of Lessee,
requirements of the holder of a mortgage or deed of trust covering the Premises,
increased valuation of the Premises, or general rate increases.  In the event
that the Premises have been occupied previously, the words "Base Period" shall
mean the last twelve months of the prior occupancy.  In the event that the
Premises have never been previously occupied, the premiums during the "Base
Period" shall be deemed to be the lowest premiums reasonably obtainable for said
insurance assuming the most nominal use of the Premises.  Provided, however, in
lieu of the Base Period, the parties may insert a dollar amount of the end of
this sentence which figure shall be considered as the insurance premium for the
Base Period:  1996 Base Year Budget.  In no event, however, shall Lessee be
responsible for any portion of the premium cost attributable to liability
insurance coverage in excess of $1,000,000 procured under paragraph 8.2.



                                       6
<PAGE>
 
          (b)  Lessee shall pay any such premium increases to Lessor within 30
days after receipt by Lessee of a copy of the premium statement or other
satisfactory evidence of the amount due.  If the insurance policies maintained
hereunder cover other improvements in addition to the Premises, Lessor shall
also deliver to the Lessee a statement of the amount of such increase
attributable to the Premises and showing in reasonable detail, the manner in
which such amount was computed.  If the term of this Lease shall not expire
concurrently with the expiration of the period covered by such insurance,
Lessee's liability for premium increases shall be prorated on an annual basis.

          (c)  If the Premises are part of a larger building, then Lessee shall
not be responsible for paying any increase in the property insurance premium
caused by the acts or omissions of any other tenant of the building of which the
Premises are a part.


     8.5  INSURANCE POLICIES.  Insurance required hereunder shall be in
companies holding a "General Policyholders Rating" of at least B plus, or such
other rating as may be required by a lender having a lien on the Premises, as
set forth in the most current issue of "Best Insurance Guide."  Lessee shall
deliver to Lessor copies of policies of liability insurance required under
Paragraph 8.1 or certificates evidencing the existence and amounts of such
insurance.  No such policy shall be cancellable or subject to reduction of
coverage or other modification except after thirty (30) days' prior written
notice to Lessor.  Lessee shall, at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with renewals or "binders" thereof,
or Lessor may order such insurance and charge the cost thereof to Lessee, which
amount shall be payable by Lessee upon demand.  Lessee shall not do or permit to
be done anything which shall invalidate the insurance policies referred to in
Paragraph 8.3.

     8.6  WAIVER OF SUBROGATION.  Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for lost or damage arising out of or incident to the perils insured against
under paragraphs 8.3 which perils occur in, on or about the Premises, whether
due to the negligence of Lessor or Lessee or their agents, employees,
contractors and/or invitees.  Lessee and Lessor shall, upon obtaining the
policies of insurance required hereunder, give notice to the insurance carrier
or carriers that the foregoing mutual waiver of subrogations is contained in
this Lease.

     8.7  INDEMNITY.  Lessee shall indemnify and hold harmless Lessor from and
against any and all claims arising from Lessee's use of the Premises, or from
the conduct of Lessee's business or from any activity, work or things done,
permitted or suffered by Lessee in or about the Premises or elsewhere and shall
further indemnify and hold harmless Lessor from and against any and all claims
arising from any breach or default in the performance of any obligation on
Lessee's part to be performed under the terms of this Lease, or arising from any
negligence of the Lessee, or any of Lessee's agents, contractors, or employees,
and from and against all costs, attorney's fees, expenses and liabilities
incurred in the defense of any such claim or any action or proceeding brought
thereon, and in case any action or proceeding be brought against Lessor by
reason of any such claim, Lessee upon notice from Lessor shall defend the same
at Lessee's expense by counsel satisfactory to Lessor.  Lessee, as a material
part of the consideration to Lessor, hereby assumes all risk of damage to
property or injury to persons in, upon or about the 



                                       7
<PAGE>
 
Premises arising from any cause and Lessee hereby waives all claims in respect
thereof against Lessor.

     8.8  EXEMPTION OF LESSOR FROM LIABILITY.  Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for damage to the goods, wares, merchandise or other property of
Lessee.  Lessee's employees, invitees, customers, or any other person in or
about the Premises, nor shall Lessor be liable for injury to the person of
Lessee.  Lessee's employees, agents or contractors whether such damage or injury
is caused by or results from fire, steam, electricity, gas, water or rain, or
from the breakage, leakage, obstruction or other defects of pipes, sprinklers,
wires, appliances, plumbing, air conditioning or lighting fixtures, or from any
other cause, whether the  said damage or injury results from conditions arising
upon the Premises or upon other portions of the building of which the Premises
are a part, or from other sources or places and regardless of whether the cause
of such damage or injury or the means of repairing the same is inaccessible to
Lessee.  Lessor shall not be liable for any damages arising from any act or
neglect of any other tenant, if any, of the building in which the Premises are
located.

paragraphs 9.4, 9.5 and 9.6, if at any time during the term of this Lease there

     9.3. PARTIAL DAMAGE -- UNINSURED LOSS.  Subject to the provisions of

which is not an Insured Loss and which falls within the classification of
Premises Partial Damage or Premises Building Partial Damage, unless cause by a
negligent or willful act of Lessee (in which event Lessee shall make the repairs

<PAGE>
 
be abated in proportion to the degree to which Lessee's use of the Premises is
impaired. Except for abatement or rent, if any, Lessee shall have no claim

destruction, repair or restoration.

          (b)  If Lessor shall be obligated to repair or restore the Premises

10.  REAL PROPERTY TAXES.

     10.1.  PAYMENT OF TAX INCREASE.  Lessor shall pay the real property tax, as
defined in paragraph 10.3, applicable to the Premises; provided, however, that
Lessee shall pay, in addition to rent, the amount, if any, by which real
property taxes applicable to the Premises increase over the fiscal real estate
tax year 1996 1997.  Such payment shall be made by Lessee within thirty (30)
days after receipt of Lessor's written statement setting forth the amount of
such increase and the computation thereof.  If the term of this Lease shall not
expire concurrently with the expiration of the tax fiscal year, Lessee's
liability for increased taxes for the last partial lease year shall be prorated
on an annual basis.

     10.2.  ADDITIONAL IMPROVEMENTS.  Notwithstanding paragraph 10.1 hereof,
Lessee shall pay to Lessor upon demand therefor the entirety of any increase in
real property tax if assessed solely by reason of additional improvements placed
upon the Premises by Lessee or at Lessee's request.

     10.3.  DEFINITION OF "REAL PROPERTY TAX".  As used herein, the term "real
property tax" shall include any form of real estate tax or assessment, general,
special, ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Premises by any authority having the direct or
indirect power to tax, including any city, state or federal government, or any
school, agricultural, sanitary, fire, street, drainage or other improvement
district thereof, as against any legal or equitable interest of Lessor in the
Premises or in the real property of which the Premises are a part, as against
Lessor's right to rent or other income therefrom, and as against Lessor's
business of leasing the Premises.  The term "real property tax" shall also
include any tax, fee, levy, assessment or charge (i) in substitution of,
partially or 



                                      10
<PAGE>
 
totally, any tax, fee, levy assessment or charge hereinabove included within the
definition of "real property tax," or (ii) the nature of which was hereinbefore
included within the definition of "real property tax," or (iii) which is imposed
for a service or right not charged prior to June 1, 1978, or, if previously
charged, has been increased since June 1, 1978, or (iv) which is imposed as a
result of a transfer, either partial or total, or Lessor's interest in the
Premises or which is added to a tax or charge hereinabove included within the
definition of real property tax by reason of such transfer, or (v) which is
imposed by reason of this transaction, any modifications or changes hereto, or
any transfers hereof.

     10.4.  JOINT ASSESSMENT.  If the Premises are not separately assessed,
Lessees liability shall be an equitable proportion of the real property taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be determined by Lessor from the respective valuations
assigned in the assessor's work sheets or such other information as may be
reasonably available.  Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

     10.5.  PERSONAL PROPERTY TAXES.

            (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere.  When  possible,
Lessee shall cause said trade fixtures, furnishings, equipment and all other
personal property to be assessed and billed separately from the real property of
Lessor.

            (b) If any of Lessee's paid personal property shall be assessed with
Lessor's real property, Lessee shall pay Lessor the taxes attributable to Lessee
within 10 days after receipt of a written statement setting forth the taxes
applicable to Lessee's property.

11.  UTILITIES. Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon. If any such services are not separately metered to
Lessee, Lessee shall pay a reasonable proportion to be determined by Lessor of
all charges jointly metered with other premises.

12.  ASSIGNMENT AND SUBLETTING.

     12.1.  LESSOR'S CONSENT REQUIRED.  Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all of any part of Lessee's interest in this Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold.  Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance  or
subletting without such consent shall be void, and shall constitute a breach of
this Lease.

     12.2.  LESSEE AFFILIATE.  Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or 



                                      11
<PAGE>
 
entity which acquires all the assets of Lessee as a going concern of the
business that is being conducted on the Premises, provided that said assignee
assumes, in full, the obligations of Lessee under this Lease. Any such
assignment shall not, in any way, affect or limit the liability of Lessee under
the terms of this Lease even if after such assignment or subletting the terms of
this Lease are materially changed or altered without the consent of Lessee, the
consent of whom shall not be necessary.

     12.3.  NO RELEASE OF LESSEE.  Regardless of Lessor's consent, no subletting
or assignment shall release Lessee of Lessee's obligation or alter the primary
liability of Lessee to pay the rent and to perform all other obligations to be
performed by Lessee hereunder.  The acceptance of rent by Lessor from any other
person shall not be deemed to be a waiver by Lessor of any provision hereof.
Consent to one assignment or subletting shall not be deemed consent to any
subsequent assignment or subletting.  In the event of default by any assignee of
Lessee or any successor of Lessee, in the performance of any of the terms
hereof, Lessor may proceed directly against Lessee without the necessity of
exhausting remedies against said  assignee.  Lessor may consent to subsequent
assignments or subletting of this Lease or amendments or modifications to this
Lease with assignees of Lessee, without notifying Lessee, or any successor of
Lessee, and without obtaining its or their consent thereto and such action shall
not relieve Lessee of liability under this Lease.

     12.4.  ATTORNEY'S FEES.  In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting of if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorneys fees incurred in connection
therewith, such attorneys fees not to exceed $350.00 for each such request.

13.  DEFAULTS; REMEDIES.

     13.1.  DEFAULTS.  The occurrence of any one ore more of the following
events shall constitute a material default and breach of this Lease by Lessee:

            (a)  The vacating or abandonment of the Premises by Lessee.

            (b)  The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, where such
failure shall continue for a period of three days after written notice thereof
from Lessor to Lessee.  In the event that Lessor serves Lessee with a Notice to
Pay Rent or Quite pursuant to applicable Unlawful Detainers statutes such Notice
to Pay Rent or Quit shall also constitute the notice required by this
subparagraph.

            (c)  The failure by Lessee to observe or perform any of the
covenants, conditions or provisions of this Lease to be observed or performed by
Lessee, other than described in paragraph (b) above, where such failure shall
continue for a period of 30 days after written notice hereof from Lessor to
Lessee; provided, however, that if the nature of Lessee's default is such that
more than 30 days are reasonably required for its cure, then Lessee shall not be
deemed to be in default if Lessee commenced such cure within said 30-day period
and 



                                      12
<PAGE>
 
thereafter diligently prosecutes such cure to completion.

           (d)  (i)  The making by Lessee of any general arrangement or
assignment for the benefit of creditors, (ii) Lessee becomes a "debtor" as
defined in 11 U.S.C. (S) 101 or any successor statute thereto (unless, in the
case of a petition filed against Lessee, the same is dismissed within 60 days);
(iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within 30
days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within 30 days.
Provided, however, in the event that any provision of this paragraph 13.1(d) is
contrary to any applicable law, such provision shall be of no force or effect.

           (e)  The discovery by Lessor that any financial statement given to
Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any successor
in interest of Lessee or any guarantor of Lessee's obligation hereunder, and any
of them, was materially false.

     13.2. REMEDIES.  In the event of any such material default or breach by
Lessee, Lessor may at any time thereafter, with or without notice or demand and
without limiting Lessor in the exercise of any right or remedy which Lessor may
have by reason of such default or breach:

           (a)  Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease shall terminate and Lessee shall
immediately surrender possession of the Premises to Lessor.  In such event
Lessor shall be entitled to recover from Lessee all damages incurred by Lessor
by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the Premises:  expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorney's fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to Paragraph 15
applicable to the unexpired term of this Lease.

           (b)  Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have abandoned the
Premises.  In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

           (c)  Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located.  Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

     13.3. DEFAULT BY LESSOR.  Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust 



                                      13
<PAGE>
 
covering the Premises whose name and address shall have theretofore been
furnished to Lessee in writing, specifying wherein Lessor has failed to perform
such obligation; provided, however, that if the nature of Lessor's obligations
is such that more than thirty (30) days are required for performance then Lessor
shall not be in default if Lessor commences performance within such 30-day
period and thereafter diligently prosecutes the same to completion.

     13.4.  LATE CHARGES.  Lessee hereby acknowledges that late payment by
Lessee to Lessor of rent and other sums due hereunder will cause Lessor to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain.  Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed on
Lessor by the terms of any mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sue due from Lessee shall
not be received by Lessor or Lessor's designee within ten (10) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to 6% of such overdue amount.  The
parties hereby agree that such late charge represents a fair and reasonable
estimate of the costs Lessor will incur by reason of late payment by Lessee.
Acceptance of such late charge by Lessor shall in no event constitute a waiver
of Lessee's default with respect to such overdue amount, nor prevent Lessor from
exercising any of the other rights and remedies granted hereunder.  In the event
that a late charge is payable hereunder, whether or not collected, for three (3)
consecutive installments of rent, then rent shall automatically become due and
payable quarterly in advance, rather than monthly, notwithstanding paragraph 4
or any other provision of this Lease to the contrary.

     13.5.  IMPOUNDS.  In the event that a late charge is payable hereunder,
whether or not collected for three (3) installments of rent or any other
monetary obligation of Lessee under the terms of this Lease, Lessee shall pay to
Lessor, if Lessor shall so request, in addition to any other payments required
under this Lease, a monthly advance installment, payable at the same time as the
monthly rent, as estimated by Lessor, for real property tax and insurance
expenses on the Premises which are payable by Lessee under the terms of this
Lease.  Such fund shall be established to insure payment due, before deliquency,
of any or all such real property taxes and insured premiums.  If the amounts
paid to Lessor by Lessee under the provisions of this paragraph are insufficient
to discharge the obligations of Lessee to pay such real property taxes and
insurance premiums as the same become due, Lessee shall pay to Lessor, upon
Lessor's demand, such additional sums necessary to pay such obligations.  All
moneys paid to Lessor under this paragraph may be intermingled with other moneys
of Lessor and shall not bear interest.  In the event of a default in the
obligations of Lessee to perform under this Lease, then any balance remaining
from funds paid to Lessor under the provisions of this paragraph may, at the
option of Lessor, be applied to the payment of any monetary default of Lessee in
lieu of being applied to the payment of real property tax and insurance
premiums.



                                      14

14.  CONDEMNATION. If the Premises or any portion thereof are taken under the
power of eminent domain, or sold under the threat of the exercise of said power
(all of which are herein called "condemnation"), this Lease shall terminate as
to the part so taken as of the date the condemning authority takes title or
possession, whichever first occurs. If more than 10% of the floor area of the
building on the Premises, or more than 25% of the land area of the Premises
which is not occupied by any building, is taken by condemnation, Lessee may, at
Lessee's option, to be exercised in writing only within ten (10) days after
Lessor shall have given Lessee written notice of such taking (or in the absence
of such notice, within ten (10) days after the condemning authority shall have
taken possession) terminate this Lease as of the date the condemning authority
takes such possession. If Lessee does not terminate this Lease in accordance
with the foregoing, this Lease shall remain in full force and effect as to the
portion of the Premises remaining, except that the rent shall be reduced in the
proportion that the floor area of the building taken bears to the total floor
area of the building situated on the Premises. No reduction of rent shall occur
if the only area taken is that which does not have a building located thereon.
Any award for the taking of all or any part of the Premises under the power of
eminent domain or any payment made under threat of the exercise of such power
shall be the property of Lessor, whether such award shall be made as
compensation for diminution in value of the leasehold or for the taking of the
fee, or as severance damages; provided, however, that Lessee shall be entitled
to any award for loss of or damage to Lessee's trade fixtures and removable
personal property. In the event that this Lease is not terminated by reason of
such condemnation, Lessor shall to the extent of severance damages received by
Lessor in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Lessee has been reimbursed
therefor by the condemning authority. Lessee shall pay any amount in excess of
such severance damages required to complete such repair.

15.  BROKER'S FEE.

          (a)  Upon execution of this Lease by both parties.  Lessor shall pay
to   NA   Licensed real estate broker(s), a fee as set forth in a separate
     --                                                                   
agreement between Lessor and said broker(s), or in the event there is no
separate agreement between Lessor and said broker(s), the sum of $ per
                                                                   ---
agreement, for brokerage services rendered by said broker(s) to Lessor in this
transaction.

          (b)  Lessor further agrees that if Lessee exercised any Option as
defined in paragraph 39.1 of this Lease, which is granted to Lessee under this
Lease, Lessor shall pay said broker(s) a fee in accordance with the schedule or
said broker(s) in effect at the time of execution of this Lease.

          (c)  Lessor agrees to pay said fee not only on behalf of any person,
corporation, association, or other entity having an ownership interest in said
real property or any party thereof, when such fee is due hereunder.  Any
transferee of Lessor's interest in this Lease, whether such transfer is by
agreement or by operation of law, shall be deemed to have assumed Lessor's
obligation under this Paragraph 15.  Said broker shall be a third party
beneficiary of the provisions of this Paragraph 15.



                                      15

16.  ESTOPPEL CERTIFICATE.

          (a)  Lessee shall at any time upon not less than (10) days' prior
written notice from Lessor execute, acknowledge and deliver to Lessor a
statement in writing (i) certifying that this Lease is unmodified and in full
force and effect (or, if modified, stating the nature of such modification and
certifying that this Lease, as so modified, is in full force and effect) and the
date to which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to Lessee's knowledge, any uncured defaults on
the part of Lessor hereunder, or specifying such defaults if any are claimed.
Any such statement may be conclusively relied upon by any prospective purchaser
or encumbrancer of the Premises.

          (b)  At Lessor's option, Lessee's failure to deliver such statement
within such time shall be a material breach of this Lease or shall be conclusive
upon Lessee (i) that this Lease is in full force and effect, without
modification except as may be represented by Lessor, (ii) that there are no
uncured defaults in Lessor's performance, and (iii) that not more than one
month's rent has been paid in advance or such failure may be considered by
Lessor as a default by Lessee under this Lease.

          (c)  If Lessor desires to finance, refinance, or sell the Premises, or
any part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statements of Lessee as may be reasonably
required by such lender or purchaser.  Such statements shall include the past
three years' financial statements of Lessee.  All such financial statements
shall be received by Lessor and such lender or purchaser in confidence and shall
be used only for the purposes herein set forth.

17. LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
owner or owners at the time in question of the fee title or a lessee's interest
in a ground lease of the Premises, and except as expressly provided in Paragraph
15, in the event of any transfer of such title or interest, Lessor herein named
(and in case of any subsequent transfers then the grantor) shall be relieved
from and after the date of such transfer of all liability as respects Lessor's
obligations thereafter to be performed, provided that any funds in the hands of
Lessor or the then grantor at the time of such transfer, in which Lessee has an
interest, shall be delivered to the grantee. The obligations contained in this
Lease to be performed by Lessor shall, subject as aforesaid, be binding on
Lessor's successors and assigns, only during their respective periods of
ownership.

18.  SEVERABILITY. The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19.  INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease, provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

20.  TIME OF ESSENCE. Time is of the essence.

21.  ADDITIONAL RENT. Any monetary obligations of Lessee to Lessor under the
terms of this Lease shall be deemed to be rent.

22.  INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS. This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
agreements or understanding pertaining to any such matter shall be effective.
This Lease may be modified in writing only, signed by the parties in interest at
the time of the modification. Except as otherwise stated in this Lease, Lessee
hereby acknowledges that neither the real estate broker listed in Paragraph 15
hereof nor any cooperating broker on this transaction nor the Lessor or any
employees or agents of any of said persons has made any oral or written
warranties or representations to Lessee relative to the condition or use by
Lessee of said Premises and Lessee acknowledges that Lessee assumes all
responsibility regarding the Occupational Safety Health Act, the legal use and
adaptability of the Premises and the compliance thereof with all applicable laws
and regulations in effect during the term of this Lease except as otherwise
specifically stated in this Lease.



                                      16
<PAGE>
  
23.  NOTICES. Any notice required or permitted to be given hereunder shall be in
writing and may be given by personal delivery or by certified mail, and if given
personally or by mail, shall be deemed sufficiently given if addressed to Lessee
or to Lessor at the address noted below the signature of the respective parties,
as the case may be. Either party may by notice to the other specify a different
address for notice purposes except that upon Lessee's taking possession of the
Premises, the Premises shall constitute Lessee's address for notice purposes. A
copy of all notices required or permitted to be given to Lessor hereunder shall
be concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by notice to Lessee.

24.  WAIVERS. No waiver by Lessor or any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision. Lessor's consent to, or approval of any act,
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of a any subsequent act by Lessee. The acceptance of rent hereunder
by Lessor shall not be a waiver of any preceding breach by Lessee of any
provision hereof, other than the failure of Lessee to pay the particular rent so
accepted, regardless of Lessor's knowledge of such preceding breach at the time
of acceptance of such rent.

25.  RECORDING. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26.  HOLDING OVER. If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, but all options and rights of
first refusal, if any, granted under the terms of this Lease shall be deemed
terminated and be of no further effect during said month to month tenancy.

27.  CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.  COVENANTS AND CONDITIONS. Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29.  BINDING EFFECT; CHOICE OF LAW. Subject to any provisions hereof restricting
assignment or subletting by Lessee and subject to the provisions of Paragraph
17, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State
wherein the Premises are located.

30.  SUBORDINATION.

          (a)  This Lease, at Lessor's option, shall be subordinate to any
ground lease, mortgage, deed of trust, or any other hypothecation or security
now or hereafter placed upon the real property of which the Premises are a part
and to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not 


                                     17  
<PAGE>
  
be disturbed if Lessee is not in default and so long as Lessee shall pay the
rent and observe and perform all of the provisions of this Lease, unless this
Lease is otherwise terminated pursuant to its terms. If any mortgagee, trustee
or ground lessor shall elect to have this Lease prior to the lien of its
mortgage, deed of trust or ground lease, and shall give written notice thereof
to Lessee, this Lease shall be deemed to prior to such mortgage, deed of trust,
or ground lease, whether this Lease is dated prior or subsequent to the date of
said mortgage, deed of trust or ground lease or the date of recording thereof.

          (b)  Lessee agrees to execute any documents required to effectuate an
attornment, a subordination or to make this Lease prior to the lien of any
mortgage, deed of trust or ground lease, as the case may be.  Lessee's failure
to execute such documents within 10 days after written demand shall constitute a
material default by Lessee hereunder, or, at Lessor's option, Lessor shall
execute such documents on behalf of Lessee as Lessee's attorney-in-fact.  Lessee
does hereby make, constitute and irrevocably appoint Lessor as Lessee's
attorney-in-fact and in Lessee's name, place and stead, to execute such
documents in accordance with this paragraph 30(b).

31.  ATTORNEY'S FEES. If either party or the broker named herein brings an
action to enforce the terms hereof or declare rights hereunder, the prevailing
party in any such action, on trial or appeal, shall be entitled to this
reasonable attorney's fees to be paid by the losing party as fixed by the court.
The provisions of this paragraph shall inure to the benefit of the broker named
herein who seeks to enforce a right hereunder.

32.  LESSOR'S ACCESS. Lessor and Lessor's agents shall have the right to enter
the Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders, or lessees, and making such
alterations, repairs, improvements or additions to the Premises or to the
building of which they are a part as Lessor may deem necessary or desirable.
Lessor may at any time place on or about the Premises any ordinary "For Sale"
signs and Lessor may at any time during the last 120 days of the term hereof
place on or about the Premises any ordinary "For Lease" signs, all without
rebate of rent or liability to Lessee.

33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34.  SIGNS. Lessee shall not place any sign upon the Premises without Lessor's
prior written consent except that Lessee shall have the right, without the prior
permission of Lessor to place ordinary and usual for rent or sublet signs
thereon.

35.  MERGER. The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to Lessor
of any or all of such subtenancies.

36.  CONSENTS. Except for paragraph 33 hereof, wherever in this Lease the
consent of one party is required to an act of the other party, such consent
shall not be unreasonably withheld.

37.  GUARANTOR. In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

38.  QUIET POSSESSION. Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease. The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Premises.

39.  OPTIONS.

defined in paragraph 12.2 of this Lease.  The Options herein granted to Lessee
are not assignable separate and apart from this Lease.

     39.3.  MULTIPLE OPTIONS.  In the event that Lessee has any multiple options
to extend or renew this Lease a later option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised.

     39.4.  EFFECT OF DEFAULT ON OPTIONS.

            (a)  Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i) during
the time commencing from the date Lessor gives to Lessee a notice of default
pursuant to paragraph 13.1(b) or 13.1(c) and continuing until the default
alleged in said notice of default is cured, or (ii) during the period of time
commending on the day after a monetary obligation to Lessor is due from Lessee
and unpaid (without any necessity for notice thereof to Lessee) continuing until
the obligation is paid, or (iii) at any time after an event of default described
in paragraphs 13.1(a), 13.1(d), or 13.1(e) (without any necessity of Lessor to
give notice of such default to Lessee), or (iv) in the event that Lessor has
given to Lessee three or more notices of default under paragraph 13.1(b), where
a late charge becomes payable under paragraph 13.4 for each of such defaults, or
paragraph 13.1(c), whether or not the defaults are cured, during the 12 month
period prior to the time that Lessee intends to exercise the subject Option.

            (b)  The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of paragraph 39.4(a).

            (c)  All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of 30 days after such obligation becomes due (without any necessity
of Lessor to give notice thereof to Lessee), or (ii) Lessee fails to commence to
cure a default specified in paragraph 13.1(c) within 30 days after the date that
Lessor gives notice to Lessee of such default and/or Lessee fails thereafter to

<PAGE>
  
completion, or (iii) Lessee commits a default described in paragraph 13.1(a),
13.1(d) or 13.1(e) (without any necessity of Lessor to give notice of such
default to Lessee), or (iv) Lessor gives to Lessee three or more notices of
default under paragraph 13.1(d), where a late charge becomes payable under
paragraph 13.4 for each default, or paragraph 13.1(c), whether or not the
defaults are cured.

40.  MULTIPLE TENANT BUILDING. In the event that the Premises are part of a
larger building or group of buildings then Lessee agrees that it will abide by,
keep and observe all reasonable rules and regulations which Lessor may take from
time to time for the management, safety, care, and cleanliness of the building
and grounds, the parking of vehicles and the preservation of good order therein
as well as for the convenience of other occupants and tenants of the building.
The violations of any such rules and regulations shall be deemed a material
breach of this Lease by Lessee.

41.  SECURITY MEASURES. Lessee hereby acknowledges that the rental payable to
Lessor hereunder does not include the cost of guard service or other security
measures, and that Lessor shall have no obligation whatsoever to provide same.
Lessee assumes all responsibility for the protection of Lessee, its agents and
invitees from acts of third parties.

42.  EASEMENTS. Lessor reserves to itself the right, from time to time, to grant
such easements, rights and dedications that Lessor deems necessary or desirable,
and to cause the recordation of Parcel Maps and restrictions, so long as such
easements, rights, dedications, Maps and restrictions do not unreasonably
interfere with the use of the Premises by Lessee. Lessee shall sign any of the
aforementioned documents upon request of Lessor and failure to do so shall
constitute a material breach of this Lease.

43.  PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise as to any
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment, and there shall survive the right on the part
of said party to institute suit for recovery of such sum. If it shall be
adjudged that there was no legal obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

44.  AUTHORITY. If Lessee is a corporation, trust, or general or limited
partnership, each individual executing this Lease on behalf of such entity
represents and warrants the he or she is duly authorized to execute and deliver
this Lease on behalf of said entity. If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after execution of this
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

45.  CONFLICT. Any conflict between the printed provisions of this Lease and the
typewritten or handwritten provisions shall be controlled by the typewritten or
handwritten provisions.

46.  ADDENDUM. See Addenda A, B, C, and D and Exhibits A and B.

ANNUAL RENT ADJUSTMENT
- ----------------------

The minimum annual rent and security deposit set forth in Paragraphs 4 and 5 of
this Lease shall be subject to an upward adjustment at the end of each ONE-(1)
YEAR PERIOD of the lease term, including option periods, if any.  The first
adjustment shall take effect beginning with the first of the month following one
(1) year from the commencement date of the Lease.  If the commencement date is
the first day of the month, then the adjustment shall take effect one (1) year
thereafter.  The new rent for each twelve (12) month period shall be determined
by adding to the annual rental for the previous twelve (12) months a sum equal
to any percentage increase that may occur in the Consumer Price Index (all
items) as published by the United States Department of Labor Bureau of Labor
Statistics for the Los Angeles-Long Beach-Riverside Metropolitan Area (1967-100
Base).  If such index is not published for the period for which a rental
adjustment determination is to be based upon, another index generally recognized
as being comparable and authoritative shall be substituted by Lessor.  Inasmuch
as the appropriate index numbers may not be available on the date when any such
adjustment is to be effective, the latest index numbers available shall be used
until such time as the appropriate index numbers become available, at which time
the calculation shall then be made as soon as reasonably possible and the rent
payment and security deposit shall be appropriately adjusted so as to include
both the correctly adjusted monthly rent and any additional amount required to
bring such adjusted monthly rent current from the intended adjustment date.



                                      30
<PAGE>
  

In no event shall said adjustment exceed three percent (3%) per annum.

this Lease are as specified in Paragraph 1.3.

         3.2.  EARLY POSSESSION. If an Early Possession Date is specified in
Paragraph 1.4 and if Lessee totally or partially occupies the Premises after the

Base Rent shall be abated for the period of such early occupancy. All other
terms of this Lease, however (including but limited to the obligations to pay
Lessee's Share of Common Area Operating Expenses and to carry the insurance
required 

                                       5
<PAGE>

shall not affect nor advance the Expiration Date of the Original Term.

         3.3.  DELAY IN POSSESSION. If for any reason Lessor cannot deliver
possession of the Premises to Lessee by the Early Possession Date, if one is
specified in Paragraph 1.4, or if no Early Possession Date is specified, by the
Commencement Date, Lessor shall not be subject to any liability therefor, nor
shall such delay affect the validity of this Lease, or the obligations of Lessee
hereunder, or extend the term hereof, but in such case, Lessee shall not, except
as otherwise provided herein, be obligated to pay rent or perform any other
obligation of Lessee under the terms of this Lease until Lessor delivers
possession of the Premises to Lessee. If possession of the Premises is not
delivered to Lessee within sixty (60) days after the Commencement Date, Lessee
may, at its option, by notice in writing to Lessor within ten (10) days after
the end of said sixty (60) day period, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided further,
however, that if such written notice of Lessee is not received by Lessor within
said ten (10) day period, Lessee's right to cancel this Lease hereunder shall
terminate and be of no further force or effect. Except as may be otherwise
provided, and regardless of when the Original Term actually commences, if
possession is not tendered to Lessee when required by this Lease and Lessee does
not terminate this Lease, as aforesaid, the period free of the obligation to pay
the Base Rent, if any, that Lessee would otherwise have enjoyed shall run from
the date to delivery of possession and continue for a period equal to the period
during which the Lessee would have otherwise enjoyed under the terms hereof, but

time designate in writing to Lessee.

               (b)  Any Common Area Operating Expenses and Real Property Taxes
that are specifically attributable to the Building or to any other building in
the Industrial Center or to the operation, repair and maintenance thereof, shall
be allocated entirely to the Building or to any other building. However, any
Common Area Operating Expenses and Real Property Taxes that are not specifically

buildings in the Industrial Center.

               (c)  The inclusion of the improvements, facilities and services
set forth in Subparagraph 4.2(a) shall not be deemed to impose an obligation
upon Lessor to either have said improvements or facilities or to provide those
services unless the Industrial Center already has the same, Lessor already
provides the services, or Lessor has agreed elsewhere in this Lease to provide
the same or some of them.

               (d)  Lessee's Share of Common Area Operating Expenses shall be
payable by Lessee within ten (10) days after a reasonably detailed statement of
actual expenses is presented to Lessee by Lessor. At Lessor's option, however,

Common Area Operating Expenses and the same shall be 

                                       7
<PAGE>
 
payable monthly or quarterly, as Lessor shall designate, during each 12-month
period of the Lease term, on the same day as the Base Rent is due hereunder.
Lessor shall deliver to Lessee within sixty (60) days after the expiration of
each calendar year a reasonably detailed statement showing Lessee's Share of the
actual Common Area Operating Expenses incurred during the preceding year. If
Lessee's payments under this Paragraph 4.2(d) during said proceeding year exceed
Lessee's Share as indicated on said statement, Lessor shall be credited the
amount of such over-payment against Lessee's Share of Common Area Operating
Expenses next becoming due. If Lessee's payments under this Paragraph 4.2(d)
during said preceding year were less than Lessee's Share as indicated on said
statement, Lessee shall pay to Lessor the amount of the deficiency within ten
(10) days after delivery by Lessor to Lessee of said statement. (subject to the
limitations of paragraph 49).

5.       SECURITY DEPOSIT.

         Lessee shall deposit with Lessor upon Lessee's execution hereof the
Security Deposit set forth in Paragraph 1.7 as security for Lessee's faithful
performance of Lessee's obligations under this Lease. If Lessor fails to pay
Base Rent or other rent or charges due hereunder, or otherwise Defaults under
this Lease(as defined in paragraph 13.1, Lessor may use, apply or retain all or
any portion of said Security Deposit for the payment of any amount due Lessor or
to reimburse or compensate Lessor for any liability, cost, expense, loss or
damage (including attorneys' fees) which Lessor may suffer or incur by reason
thereof. If Lessor uses or applies all or any portion of said Security Deposit,
Lessee shall within ten (10) days after written request thereof deposit monies
with Lessor sufficient to restore said Security Deposit to the full amount
required by this Lease. Any time the Base Rent increases during the term of this
Lease, Lessee shall, upon written request from Lessor, deposit additional monies
with Lessor as an addition to the Security Deposit so that the total amount of
the Security Deposit shall at all times bear the same proportion to the then
current Base Rent as the initial Security Deposit bears to the initial Base Rent
set forth in Paragraph 1.5. Lessor shall not be required to keep all or any part
of the Security Deposit separate from its general accounts. Lessor shall, at the
expiration or earlier termination of the term hereof and after Lessee has
vacated the Premises, return to Lessee (or, at Lessor's option, to the last
assignee, if any, of Lessee's interest herein), that portion of the Security
Deposit not used or applied by Lessor. Unless otherwise expressly agreed in
writing by Lessor, no part of the Security Deposit shall be considered to be
held in trust, to bear interest or other increment of its use, or to be
prepayment for any monies to be paid by Lessee under this Lease.

6.       USE.

         6.1.  PERMITTED USE.

               (a)  Lessee shall use and occupy the Premises only for the
Permitted Use set forth in Paragraph 1.8 or any other legal use which is

permit the use of the Premises in a manner that is unlawful, creates waste or
nuisance, or that disturbs owners and/or occupants of, or causes damage to the
Premises or neighboring premises or properties.

<PAGE>
 
               (b)  Lessor hereby agrees to not unreasonably withhold or delay
its consent to any written request by Lessee, Lessee's assignees or subtenants,
and by prospective assignees and subtenants of Lessee, its assignees and
subtenants, for a modification of said Permitted Use, so long as the same will
not impair the structural integrity of the improvements on the Premises or in
the Building or the mechanical or electrical systems therein, does not conflict
with uses by other lessees, is not significantly more burdensome to the Premises
or the Building and the improvements thereon, and is otherwise permissible
pursuant to this Paragraph 6. If Lessor elects to withhold such consent, Lessor
shall within five (5) business days after such request give a written
notification of same, which notice shall include an explanation of Lessor's
reasonable objections to the change in use.

Substance" as used in this Lease shall mean any product, substance, chemical,
material or waste whose presence, nature, quantity and/or intensity of
existence, use, manufacture, disposal, transportation, spill, release or effect,
either by itself or in combination with other materials expected to be on the
Premises, is either: (i) potentially injurious to the public health, safety or
welfare, the environment, or the Premises; (ii) regulated or monitored by any
governmental authority, or (iii) a basis for potential liability of Lessor to
any governmental agency or third party under any applicable statue or common law
theory. Hazardous Substance shall include, but not be limited to, hydrocarbons,
petroleum, gasoline, crude oil or any products or by-products thereof. Lessee
shall not engage in any activity in or about the Premises which constitutes a
Reportable Use (as hereinafter defined) of Hazardous Substances without the
express prior written consent of Lessor and compliance in a timely manner (at
Lessee's sole cost and expense) with all Applicable Requirements (as defined in
Paragraph 6.3). "Reportable Use" shall mean (i) the installation or use of any
above or below ground storage tank, (ii) the generation, possession, storage,
use, transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with, any governmental authority and (iii) the presence
in, on or about the Premises of a Hazardous Substance with respect to which any
Applicable Laws require that a notice be given to persons entering or occupying
the Premises or neighboring properties. Notwithstanding the foregoing, Lessee
may, without Lessor's prior consent, but upon notice to Lessor and in compliance
with all Applicable Requirements, use any ordinary and customary materials
reasonably required to be used by Lessee in the normal course of the Permitted
Use, so long as such use is not a Reportable Use and does not expose the
Premises or neighboring properties to any meaningful risk of contamination or
damage or expose Lessor to any liability therefor. In addition, Lessor may (but
without any obligation to do so) condition its consent to any Reportable Use of
any Hazardous Substance by Lessee upon Lessee's giving Lessor such additional
assurances as Lessor, in its reasonable discretion, deems necessary to protect
itself, the Public, the Premises, and the environment against damage,
contamination or injury and/or liability therefor, including but not limited to
the installation (and, at Lessor's option, removal on or before Lease expiration
or earlier termination) of reasonably necessary protective modifications to the
Premises (such as concrete encasements) and/or the deposit of an additional
Security Deposit under paragraph 5 hereof.

<PAGE>
 
               (b)  DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable
cause to believe, that a Hazardous Substance has come to be located in, on,
under or about the Premises or the Building, other than as previously consented
to by Lessor, Lessee shall immediately give Lessor written notice thereof,
together with a copy of any statement, report, notice, registration,
application, permit, business plan, license, claim, action, or proceeding given
to, or received from, any governmental authority or private party concerning the
presence, spill, release, discharge of, or exposure to, such Hazardous Substance
including but not limited to such documents as may be involved in any Reportable
Use involving the Premises. Lessee shall not cause or permit any Hazardous
Substance to be spilled or exposed in, on, under or about the Premises
(including, without limitation, through the plumbing or sanitary sewer system).

               (c)  INDEMNIFICATION. Lessee shall indemnify, protect, defend and
hold Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all damages, liabilities, judgments,
costs, claims, liens, expenses, penalties, loss of permits and attorneys' and
consultants' fees arising out of or involving any Hazardous Substance brought
onto the Premises by or for Lessee or by anyone under Lessee's control. Lessee's
obligations under this Paragraph 6.2(c) shall include, but not be limited to,
the effects of any contamination or injury to person, property or the
environment created or suffered by Lessee, and the cost of investigation
(including consultants' and attorneys' fees and testing), removal, remediation,
restoration and/or abatement thereof, or of any contamination therein involved,
and shall survive the expiration or earlier termination of this Lease. No
termination, cancellation or release agreement entered into by Lessor and Lessee
shall release Lessee from its obligations under this Lease with respect to
Hazardous Substances, unless specifically so agreed by Lessor in writing at the
time of such agreement.

         6.3.  LESSEE'S COMPLIANCE WITH REQUIREMENTS. Lessee shall, at Lessee's
sole cost and expense, fully, diligently and in a timely manner, comply with all
"Applicable Requirements," which term is used in this Lease to mean all laws,
rules, regulations, ordinances, directives, covenants, easements and
restrictions of record, permits, the requirements of any applicable fire
insurance underwriter or rating bureau, and the recommendations of Lessor's
engineers and/or consultants, relating in any manner to the Premises (including
but not limited to matters pertaining to (i) industrial hygiene, (ii)
environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions, and (iii) the use, generation, manufacture, production,
installation, maintenance, removal, transportation, storage, spill, or release
of any Hazardous Substance), now in effect or which may hereafter come into
effect. Lessee shall, within five (5) days after receipt of Lessor's written
request, provide Lessor with copies of all documents and information, including
but not limited to permits, registrations, manifests, applications, reports and
certificates, evidencing Lessee's compliance with any Applicable Requirements
specified by Lessor, and shall immediately upon receipt, notify Lessor in
writing (with copies of any documents involved) of any threatened or actual
claim, notice, citation, warning, complaint or report pertaining to or involving
failure by Lessee or the Premises to comply with any Applicable Requirements.

         6.4.  INSPECTION; COMPLIANCE WITH LAW. Lessor, Lessor's agents,
employees, contractors and designated representatives, and the holders of any
mortgages, deeds of trust or 

                                       10
<PAGE>
 
ground leases on the Premises ("Lenders") shall have the right to enter the
Premises at any time in the case of an emergency, and otherwise at reasonable
times, for the purpose of inspecting the condition of the Premises and for
verifying compliance by Lessee with this Lease and all Applicable Requirements
(as defined in Paragraph 6.3), and Lessor shall be entitled to employ experts
and/or consultants in connection therewith to advise Lessor with respect to
Lessee's activities, including but not limited to Lessee's installation,
operation, use, monitoring, maintenance, or removal of any Hazardous Substance
on or from the Premises. The costs and expenses of any such inspections shall be
paid by the party requesting same, unless a Default or Breach of this Lease by
Lessee or a violation of Applicable Requirements or a contamination, caused or
materially contributed to by Lessee, is found to exist or to be imminent, or
unless the inspection is requested or ordered by a governmental authority as the
result of any such existing or imminent violation or contamination. In such
case, Lessee shall upon request reimburse Lessor or Lessor's Lender, as the case
may be, for the costs and expenses of such inspections.

7.       MAINTENANCE, REPAIRS, UTILITY INSTALLATIONS, TRADE FIXTURES AND 
         ALTERATIONS.

         7.1.  LESSEE'S OBLIGATIONS.

               (a)  Subject to the provisions of Paragraphs 2.2 (Condition), 2.3
(Compliance with Covenants, Restrictions and Building Code), 7.2 (Lessor's
Obligations), 9 (Damage or Destruction), and 14 (Condemnation), Lessee shall, at
Lessee's sole cost and expense and at all times, keep the Premises and every
part thereof in good order, condition and repair (whether or not such portion of
the Premises requiring repair, or the means of repairing the same, are
reasonably or readily accessible to Lessee, and whether or not the need for such
repairs occurs as a result of Lessee's use, any prior use, the elements or the
age of such portion of the Premises), including, without limiting the generality
of the foregoing, all equipment or facilities specifically serving the Premises,
such as plumbing, heating, air conditioning, ventilating, electrical, lighting
facilities, boilers, fired or unfired pressure vessels, fire hose connections if
within the Premises, fixtures, interior walls, interior surfaces of exterior
walls, ceilings, floors, windows, doors, plate glass, and skylights, but
excluding any items which are the responsibility of Lessor pursuant to Paragraph
7.2 below. Lessee, in keeping the Premises in good order, condition and repair,
shall exercise and perform good maintenance practices. Lessee's obligations
shall include restorations, replacements or renewals when necessary to keep the
Premises and all improvements thereon or a part thereof in good order, condition
and state of repair.

               (b)  Lessee shall, at Lessee's sole cost and expense, procure and
maintain a contract, with copies to Lessor, in customary form and substance for
and with a contractor specializing and experienced in the inspection,
maintenance and service of the heating, air conditioning and ventilation system
for the Premises. However, Lessor reserves the right, upon notice to Lessee, to
procure and maintain the contract for the heating, air conditioning and
ventilating systems, and if Lessor so elects, Lessee shall reimburse Lessor,
upon demand, for the cost thereof.

               (c)  If Lessee fails to perform Lessee's obligations under
this Paragraph 7.1, Lessor may enter upon the Premises after ten (10) days'
prior written notice to Lessee (except in 

                                       11
<PAGE>
 
the case of an emergency, in which case no notice shall be required), perform
such obligations on Lessee's behalf, and put the Premises in good order,
condition and repair, in accordance with Paragraph 13.2 below.

         7.2.  LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 2.2
(Condition), 2.3 (Compliance with Covenants, Restrictions and Building Code),
4.2 (Common Area Operating Expenses), 6 (Use), 7.1 (Lessee's Obligations), 9
(Damage or Destruction) and 14 (Condemnation), Lessor, subject to reimbursement
pursuant to Paragraph 4.2 shall keep in good order, condition and repair the
foundations, exterior walls, structural condition of interior bearings walls,
exterior roof, fire sprinkler and/or standpipe and hose (if located in the
Common Areas) or other automatic fire extinguishing system including fire alarm
and/or smoke detection systems and equipment, fire hydrants, parking lots,
walkways, parkways, driveways, landscaping, fences, signs and utility systems
serving the Common Areas and all parts thereof, as well as providing the
services for which there is a Common Area Operating Expense pursuant to
Paragraph 4.2. Lessor shall not be obligated to paint the exterior or interior
surfaces of exterior walls nor shall Lessor be obligated to maintain, repair or
replace windows, doors or plate glass of the Premises. Lessee expressly waives
the benefit of any statute now or hereafter in effect which would otherwise
afford Lessee the right to make repairs at Lessor's expense or to terminate this
Lease because of Lessor's failure to keep the Building, Industrial Center or
Common Areas in good order, condition and repair.

         7.3.  UTILITY INSTALLATIONS, TRADE FIXTURES, ALTERATIONS.

               (a)  DEFINITIONS; CONSENT REQUIRED. The term "Utility
Installations" is used in this Lease to refer to all air lines, power panels,
electrical distribution, security, fire protection systems, communications
systems, lighting fixtures, hearing, ventilating and air conditioning equipment,
plumbing, and fencing in, on or about the Premises. The term "Trade Fixtures"
shall mean Lessee's machinery and equipment which can be removed without doing
material damage to the Premises. The term "Alterations" shall mean any
modification of the improvements on the Premises which are provided by Lessor
under the terms of this Lease, other than Utility Installations or Trade
Fixtures. "Lessee-Owned Alterations and/or Utility Installations" are defined as
Alterations and/or Utility Installations made by Lessee that are not yet owned
by Lessor pursuant to Paragraph 7.4(a). Lessee shall not make nor cause to be
made any Alterations or Utility Installations in, on, under or about the
Premises without Lessor's prior written consent. Lessee may, however, make non-
structural Utility Installations to the Interior of the Premises (excluding the
roof) without Lessor's consent but upon notice to Lessor, so long as they are
not visible from the outside of the Premises, do not involve puncturing,
relocating or removing the roof or any existing walls, or changing or
interfering with the fire sprinkler or fire detection systems and the cumulative
cost thereof during the term of this Lease as extended does not exceed
$2,500.00.

               (b)  CONSENT. Any Alterations or Utility Installations that
Lessee shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with detailed plans. All consents given by
Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific consent,
shall be deemed conditioned upon: (i) Lessee's acquiring all 

                                       12
<PAGE>
 
applicable permits required by governmental authorities; (ii) the furnishing of
copies of such permits together with a copy of the plans and specifications for
the Alteration or Utility Installation to Lessor prior to commencement of the
work thereon; and (iii) the compliance by Lessee with all conditions of said
permits in a prompt and expeditious manner. Any Alterations or Utility
Installations by Lessee during the term of this Lease shall be done in a good
and workmanlike manner, with good and sufficient materials, and be in compliance
with all Applicable Requirements. Lessee shall promptly upon completion thereof
furnish Lessor with as-built plans and specifications therefor. Lessor may, (but
without obligation to do so) condition its consent to any requested Alternation
or Utility Installation that costs $2,500.00 or more upon Lessee's providing
Lessor with a lien and completion bond in an amount equal to one and one-half
times the estimated cost of such Alteration or Utility Installation.

               (c)  LIEN PROTECTION. Lessee shall pay when due all claims
for labor or materials furnished or alleged to have been furnished to or for
Lessee at or for use on the Premises, which claims are or may be secured by any
mechanic's or materialmen's lien against the Premises or any interest therein.
Lessee shall give Lessor not less than ten (10) days' notice prior to the
commencement of any work in, on, or about the Premises, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises as
provided by law. If Lessee shall, in good faith, contest the validity of any
such lien, claim or demand, then Lessee shall, at its sole expense, defend and
protect itself, Lessor and the Premises against the same and shall pay and
satisfy any such adverse judgment that may be rendered thereon before the
enforcement thereof against the Lessor or the Premises. If Lessor shall require,
Lessee shall furnish to Lessor a surety bond satisfactory to Lessor in an amount
equal to one and one-half times the amount of such contested lien claim or
demand, indemnifying Lessor against liability for the same, as required by law
for the holding of the Premises free from the effect of such lien or claim. In
addition, Lessor may require Lessee to pay Lessor's attorneys' fees and costs in
participating in such action if Lessor shall decide it is to its best interest
to do so.

         7.4.  OWNERSHIP, REMOVAL, SURRENDER, AND RESTORATION.

               (a)  OWNERSHIP. Subject to Lessor's right to require their
removal and to cause Lessee to become the owner thereof as hereinafter provided
in this Paragraph 7.4, all Alterations and Utility Installations made to the
Premises by Lessee shall be the property of and owned by Lessee, but considered
a part of the Premises. Lessor may, at any time and at its option, elect in
writing to Lessee to be the owner of all or any specified part of the
Lessee-Owned Alterations and Utility Installations. Unless otherwise instructed
per Subparagraph 7.4(b) hereof, all Lessee-Owned Alterations and Utility
Installations shall, at the expiration or earlier termination of this Lease,
become the property of Lessor and remain upon the Premises and be surrendered
with the Premises by Lessee.

               (b)  REMOVAL. Unless otherwise agreed in writing, Lessor may
require that any or all Lessee-Owned Alterations or Utility Installations be
removed by the expiration or earlier termination of this Lease, notwithstanding
that their installation may have been consented to by Lessor. Lessor may require
the removal at any time of all or any part of any Alterations or Utility
Installations made without the required consent of Lessor.

                                       13
<PAGE>
 
               (c)  SURRENDER/RESTORATION. Lessee shall surrender the Premises
by the end of the last day of the Lease term or any earlier termination date,
clean and free of debris and in good operating order, condition and state of
repair, ordinary wear and tear excepted. Ordinary wear and tear shall not
include any damage or deterioration that would have been prevented by good
maintenance practice or by Lessee performing all of its obligations under this
Lease. Except as otherwise agreed or specified herein, the Premises, as
surrendered, shall include the Alterations and Utility Installations. The
obligation of Lessee shall include the repair of any damage occasioned by the
installation, maintenance or removal of Lessee's Trade Fixtures, furnishings,
equipment, and Lessee-Owned Alterations and Utility Installations, as well as
the removal of any storage tank installed by or for Lessee, and the removal,
replacement, or remediation of any soil, material or ground water contaminated
by Lessee, all as may then be required by Applicable Requirements and/or good
practice. Lessee's Trade Fixtures shall remain the property of Lessee and shall
be removed by Lessee subject to its obligation to repair and restore the
Premises per this Lease.

8.       INSURANCE; INDEMNITY.

         8.1.  PAYMENT OF PREMIUMS. The cost of the premiums for the insurance
policies maintained by Lessor under this Paragraph 8 shall be a Common Area
Operating Expense pursuant to Paragraph 4.2 hereof. Premiums for policy periods
commencing prior to, or extending beyond, the term of this Lease shall be
pro-rated to coincide with the corresponding Commencement Date or Expiration
Date.

         8.2.  LIABILITY INSURANCE.

               (a)  CARRIED BY LESSEE. Lessee shall obtain and keep in force
during the term of this Lease a Commercial General Liability policy of insurance
protecting Lessee, Lessor and any Lender(s) whose names have been provided to
Lessee in writing (as additional insurers) against claims for bodily injury,
personal injury and property damage based upon, involving or arising out of the
ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto. Such insurance shall be on an occurrence basis providing
single limit coverage in an amount not less than $1,000,000 per occurrence with
an "Additional Insured-Managers or Lessors of Premises" endorsement and contain
the "Amendment of the Pollution Exclusion" endorsement for damage caused by
heat, smoke or fumes from a hostile fire. The policy shall not contain any
intra-insured exclusions as between insured persons or organizations, but shall
include coverage for liability assumed under this Lease as an "insured contract"
for the performance of Lessee's indemnity obligations under this Lease. The
limits of said insurance required by this Lease or as carried by Lessee shall
not, however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder. All insurance to be carried by Lessee shall be primary to and not
contributory with any similar insurance carried by Lessor, whose insurance shall
be considered excess insurance only.

               (b)  CARRIED BY LESSOR. Lessor shall also maintain liability
insurance described in Paragraph 8.2(a) above. In addition to and not in lieu
of, the insurance required to be maintained by Lessee, Lessee shall not be named
as an additional insured therein.

                                       14
<PAGE>
 
         8.3.     PROPERTY INSURANCE-BUILDING, IMPROVEMENTS AND RENTAL VALUE.

                  (a) BUILDING AND IMPROVEMENTS. Lessor shall obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and to any Lender(s), insuring against loss or
damage to the Premises. Such insurance shall be for full replacement cost, as
the same shall exist from time to time, or the amount required by any Lender(s),
but in no event more than the commercially reasonable and available insurable
value thereof if, by reason of the unique nature or age of the improvements
involved, such latter amount is less than full replacement cost. Lessee-Owned
Alterations and Utility Installations, Trade Fixtures and Lessee's personal
property shall be insured by Lessee pursuant to Paragraph 8.4. If the coverage
is available and commercially appropriate, Lessor's policy or policies shall
insure against all risks of direct physical loss or damage (except the perils of
flood and/or earthquake unless required by a Lender), including coverage for any
additional costs resulting from debris removal and reasonable amounts of
coverage for the enforcement of any ordinance or law regulating the
reconstruction or replacement of any undamaged sections of the Building required
to be demolished or removed by reason of the enforcement of any building,
zoning, safety or land use laws as the result of a covered loss, but not
including plate glass insurance. Said policy or policies shall also contain an
agreed valuation provision in lieu of any co-insurance clause, waiver of
subrogation, and inflation guard protection causing an increase in the annual
property insurance coverage amount by a factor of not less than the adjusted
U.S. Department of Labor Consumer Price Index for All Urban Consumers for the
city nearest to where the Premises are located.

                  (b) RENTAL VALUE. Lessor shall also obtain and keep in force
during the term of this Lease a policy or policies in the name of Lessor, with
loss payable to Lessor and Lender(s), insuring the loss of the full rental and
other charges payable by all lessees of the Building to Lessor for one year
(including all Real Property Taxes, insurance costs, all Common Area Operating
Expenses and any scheduled rental increases). Said insurance may provide that in
the event the Lease is terminated by reason of an insured loss, the period of
indemnity for such coverage shall be extended beyond the date of the completion
of repairs or replacement of the Premises, to provide for one full year's loss
of rental revenues from the date of any such loss. Said insurance shall contain
an agreed valuation provision in lieu of any co-insurance clause, and the amount
of coverage shall be adjusted annually to reflect the projected rental income,
Real Property Taxes, insurance premium costs and other expenses, if any,
otherwise payable, for the next 12-month period. Common Area Operating Expenses
shall include any deductible amount in the event of such loss.

                  (c) ADJACENT PREMISES. Lessee shall pay for an increase in the
premiums for the property insurance of the Building and for the Common Areas or
other buildings in the Industrial Center if said increase is caused by Lessee's
acts, omissions, use or occupancy of the Premises.

                  (d) LESSEE'S IMPROVEMENTS. Since Lessor is the insuring Party,
Lessor shall not be required to insure Lessee-Owned Alternations and Utility
Installations unless the item in question has become the property of Lessor
under the terms of this Lease.

                                       15
<PAGE>
 
         8.4. LESSEE'S PROPERTY INSURANCE. Subject to the requirements of
Paragraph 8.5, Lessee at its cost shall either by separate policy or, at
Lessor's option, by endorsement to a policy already carried, maintain insurance
coverage on all of Lessee's personal property, Trade Fixtures and Lessee-Owned
Alterations and Utility Installations in, on, or about the Premises similar in
coverage to that carried by Lessor as the Insuring Party under Paragraph 8.3(a).
Such insurance shall be full replacement cost coverage with a deductible not to
exceed $1,000 per occurrence. The proceeds from any such insurance shall be used
by Lessee for the replacement of personal property and the restoration of Trade
Fixtures and Lessee-Owned Alterations and Utility Installations. Upon request
from Lessor, Lessee shall provide Lessor with written evidence that such
insurance is in force.

         8.5. INSURANCE POLICIES. Insurance required hereunder shall be in
companies duly licensed to transact business in the state where the Premises are
located, and maintaining during the policy term a "General Policyholders Rating"
of at least B+, V, or such other rating as may be required by a Lender, as set
forth in the most current issue of "Best's Insurance Guide." Lessee shall not do
or permit to be done anything which shall invalidate the insurance policies
referred to in this Paragraph 8, Lessee shall cause to be delivered to Lessor,
within seven (7) days after the earlier of the Early Possession Date or the
Commencement Date, certified copies of, or certificates evidencing the existence
and amounts of, the insurance required under Paragraph 8.2(a) and 8.4. No such
policy shall be cancelable or subject to modification except after thirty (30)
days' prior written notice to Lessor. Lessee shall at least thirty (30) days
prior to the expiration of such policy furnish Lessor with evidence of renewals
or "insurance binders" evidencing renewal thereof, or Lessor may order such
insurance and charge the cost thereof to Lessee, which amount shall be payable
by Lessee to Lessor upon demand.

         8.6. WAIVER OF SUBROGATION. Without affecting any other rights or
remedies, Lessee and Lessor each hereby release and relieve the other, and waive
their entire right to recover damages (whether in contract or in tort) against
the other, for loss or damage to their property arising out of or incident to
the perils required to be insured against under Paragraph 8. The effect of such
releases and waivers of the right to recover damages shall not be limited by the
amount of insurance carried or required, or by any deductibles applicable
thereto. Lesser and Lessee agree to have their respective insurance companies
issuing property damage insurance waive any right to subrogation that such
companies may have against Lessor or Lessee, as the case may be, so long as the
insurance is not invalidated thereby.

         8.7. INDEMNITY. Except for Lessor's negligence and/or breach of express
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, loss of permits, attorneys' and consultants'
fees, expenses and/or liabilities arising out of, involving, or in connection
with, the occupancy of the Premises by Lessee, the conduct of Lessee's business,
any act, omission or neglect of Lessee, its agents, contractors, employees or
invitees, and out of any Default or Breach by Lessee in the performance in a
timely manner of any obligation on Lessee's part to be performed under this
Lease. The foregoing shall include, but not be limited to, the defense or
pursuit of any claim or any action or proceeding involved therein, and whether
or not (in the case 

                                       16
<PAGE>
 
of claims made against Lessor) litigated and/or reduced to judgment. In case any
action or proceeding be brought against Lessor by reason of any of the foregoing
matters, Lessee upon notice from Lessor shall defend the same at Lessee's
expense by counsel reasonably satisfactory to Lessor and Lessor shall cooperate
with Lessee in such defense. Lessor need not have first paid any such claim in
order to be so indemnified.

         8.8. EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinkles, wires,
appliances, plumbing, air conditioning or lighting fixtures, or from any other
cause, whether said injury or damage results from conditions arising upon the
Premises or upon other portions of the Building of which the Premises are a
part, from other sources or places, and regardless of whether the cause of such
damage or injury or the means of repairing the same is accessible or not. Lessor
shall not be liable for any damages arising from any act or neglect of any other
lessee of Lessor nor from the failure by Lessor to enforce the provisions of any
other lease in the Industrial Center. Notwithstanding Lessor's negligence or
breach of this Lease, Lessor shall under no circumstances be liable for injury
to Lessee's business or for any loss of income or profit therefrom.

9.       DAMAGE OR DESTRUCTION.

         9.1.     DEFINITIONS.

                  (a) "PREMISES PARTIAL DAMAGE" shall mean damage or destruction
to the Premises, other than Lessee-Owned Alterations and Utility Installations,
the repair cost of which damage or destruction is less than fifty percent (50%)
of the then Replacement Cost (as defined in Paragraph 9.1(d)) of the Premises
(excluding Lessee-Owned Alterations and Utility Installations and Trade
Fixtures) immediately prior to such damage of destruction.

                  (b) "PREMISES TOTAL DESTRUCTION" shall mean damage or
destruction to the Premises, other than Lessee-Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is fifty percent
(50%) or more of the then Replacement Cost of the Premises (excluding
Lessee-Owned Alterations and Utility Installations and Trade Fixtures)
immediately prior to such damage or destruction. In addition, damage or
destruction to the Building, other than Lessee-Owned Alterations and Utility
Installations and Trade Fixtures of any lessees of the Building, the cost of
which damage or destruction is fifty percent (50%) or more of the then
Replacement Cost (excluding Lessee-Owned Alterations and Utility Installations
and Trade Fixtures of any lessees of the Building) of the Building shall, at the
option of Lessor, be deemed to be Premises Total Destruction.

                  (c) "INSURED LOSS" shall mean damage or destruction to the
Premises, other than Lessee-Owned Alterations and Utility Installations and
Trade Fixtures, which was caused by an event required to be covered by the
insurance described in Paragraph 8.3(a) irrespective of any deductible amounts
or coverage limits involved.

                                       17
<PAGE>
 
                  (d) "REPLACEMENT COST" shall mean the cost to repair or
rebuild the improvements owned by Lessor at the time of the occurrence to their
condition existing immediately prior thereto, including demolition, debris
removal and upgrading required by the operation of applicable building codes,
ordinances or laws, and without deduction for depreciation.

                  (e) "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence
or discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in Paragraph 6.2(a), in or, on, or under the
Premises.

         9.2. PREMISES PARTIAL DAMAGE - INSURED LOSS. If Premises Partial Damage
that is an insured loss occurs, then Lessor shall, at Lessor's expense, repair
such damage (but not Lessee's Trade Fixtures or Lessee-Owned Alterations and
Utility Installations) as soon as reasonably possibly and this Lease shall
continue in full force and effect. In the event, however, that there is a
shortage of insurance proceeds and such shortage is due to the fact that, by
reason of the unique nature of the improvements in the Premises, full
replacement cost insurance coverage was not commercially reasonable and
available, Lessor shall have no obligation to pay for the shortage in insurance
proceeds or to fully restore the unique aspects of the Premises unless Lessee
provides Lessor with the funds to cover same, or adequate assurance thereof,
within said ten (10) days following receipt of written notice of such shortage
and request therefor. If Lessor receives said funds or adequate assurance
thereof within said ten (10) day period, Lessor shall complete them as soon as
reasonably possible and this Lease shall remain in full force and effect. If
Lessor does not receive such funds or assurance within said period, Lessor may
nevertheless elect by written notice to Lessee within ten (10) days thereafter
to make such restoration and repair as is commercially reasonable with Lessor
paying any shortage in proceeds, in which case this Lease shall remain in full
force and effect. If Lessor does not receive such funds or assurance within such
ten (10) day period, and if Lessor does not so elect to restore and repair, then
this Lease shall terminate sixty (60) days following the occurrence of the
damage or destruction. Unless otherwise agreed, Lessee shall in no event have
any right to reimbursement from Lessor for any funds contributed by Lessee to
repair any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to Paragraph 9.3 rather than Paragraph 9.2,
notwithstanding that there may be some insurance coverage, but the net proceeds
of any such insurance shall be made available for the repairs if made by either
Party.

         9.3. PARTIAL DAMAGE - UNINSURED LOSS. If Premises Partial Damage that
is not an insured loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect), Lessor may at Lessor's
option, either (i) repair such damage as soon as reasonably possible at Lessor's
expense, in which event this Lease shall continue in full force and effect, or
(ii) give written notice to Lessee within thirty (30) days after receipt by
Lessor of knowledge of the occurrence of such damage of Lessor's desire to
terminate this Lease as of the date sixty (60) days following the date of such
notice. In the event Lessor elects to give such notice of Lessor's intention to
terminate this Lease, Lessee shall have the right within ten (10) days after the
receipt of such notice to give written notice to Lessor of Lessee's commitment
to pay for the repair of such damage totally at Lessee's expense and without
reimbursement from Lessor. Lessee shall 

                                       18
<PAGE>
 
provide Lessor with the required funds or satisfactory assurance thereof within
thirty (30) days following such commitment from Lessee. In such event this Lease
shall continue to full force and effect, and Lessor shall proceed to make such
repairs as soon as reasonably possible after the required funds are available.
If Lessee does not give such notice and provide the funds or assurance thereof
within the times specified above, this Lease shall terminate as of the date
specified in Lessor's notice of termination.

         9.4. TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or not the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in Paragraph 9.7

         9.5. DAMAGE NEAR END OF TERM. If at any time during the last six (6)
months of the term of this Lease is damage for which the cost to repair exceeds
one month's Base Rent, whether or not an Insured Loss, Lessor may, at Lessor's
option, terminate this Lease effective sixty (60) days following the date of
occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence of such
damage. Provided, however, if Lessee at that time has an exercisable option to
extend this Lease or to purchase the Premises, then Lessee may preserve this
Lease by (a) exercising such option, and (b) providing Lessor with any shortage
in insurance proceeds (or adequate assurance thereof) needed to make the repairs
on or before the earlier of (i) the date which is ten (10) days after Lessee's
receipt of Lessor's written notice purporting to purporting to terminate this
Lease, or (ii) the day prior to the date upon which such option expires. If
Lessee duly exercises such option during such period and provides Lessor with
funds (or adequate assurance thereof) to cover any shortage in insurance
proceeds, Lessor shall, at Lessor's expense repair such damage as soon as
reasonably possible and this Lease shall continue in full force and effect. If
Lessee falls to exercise such option and provide such funds or assurance during
such period, then this Lease shall terminate as of the date set forth in the
first sentence of this Paragraph 9.5.

         9.6.     ABATEMENT OF RENT; LESSEE'S REMEDIES.

                  (a) In the event of (i) Premises Partial Damage or (ii)
Hazardous Substance Condition for which Lessee is not legally responsible, the
Base Rent, Common Area Operating Expenses and other charges, if any, payable by
Lessee hereunder for the period during which such damage or condition, its
repair, remediation or restoration continue, shall be abated in proportion to
the degree to which Lessee's use of the Premises is impaired, but not in excess
of proceeds from insurance required to be carried under Paragraph 8.3(b). Except
for abatement of Base Rent, Common Area Operating Expenses and other charges, if
any, as aforesaid, all other obligations of Lessee hereunder shall be performed
by Lessee, and Lessee shall have no claim against Lessor for any damage suffered
by reason of any such damage, destruction, repair, remediation or restoration.

                                       19
<PAGE>
 
                  (b) If Lessor shall be obligated to repair or restore the
Premises under the provisions of this Paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
ninety (90) days after such obligation shall accrue, Lessee may, at any time
prior the commencement of such repair or restoration, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's election
to terminate the Lease on a date not less than sixty (60) days following the
giving of such notice. If Lessee gives such notice to Lessor and such Lenders
and such repair or restoration is not commenced within thirty (30) days after
receipt of such notice, this Lease shall terminate as specified in said notice.
If Lessor or a Lender commences the repair or restoration of the Premises within
thirty (30) days after the receipt of such notice, this Lease shall continue in
full force and effect. "Commence" as used in this Paragraph 9.6 shall mean
either the unconditional authorization of the preparation of the required plans,
or the beginning of the actual work on the Premises, whichever occurs first.

         9.7. HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance occurs,
unless Lessee is legally responsible therefor (in which case Lessee shall make
the investigation and remediation thereof required by Applicable Requirements
and this Lease shall continue in full force and effect but subject to Lessor's
rights under Paragraph 8.2(c) and Paragraph 13). Lessor may at Lessor's option
either (i) investigate and remediate such Hazardous Substance Condition, if
required, as soon as reasonably possible at Lessor's expense, in which event
this Lease shall continue in full force and effect, or (ii) if the estimated
cost to investigate and remediate such condition exceeds twelve (12) times the
then monthly Base Rent or $100,000 whichever is greater, give written notice to
Lessee within thirty (30) days after receipt by Lessor of knowledge of the
occurrence of such Hazardous Substance Condition of Lessor's desire to terminate
this Lease as of the date sixty (60) days following the date of such notice. In
the event Lessor elects to give such notice of Lessor's intention to terminate
this Lease, Lessee shall have the right within ten (10) days after the receipt
of such notice to give written notice to Lessor of Lessee's commitment to pay
for the excess costs for the investigation and remediation of such Hazardous
Substance Condition to the extent required by Applicable Requirement, over (b)
an amount equal to twelve (12) times the then monthly Base Rent or $100,000,
whichever is greater. Lessee shall provide Lessor with the funds required of
Lessee or satisfactory assurance thereof within thirty (30) days following said
commitment by Lessee. In such event this Lease shall continue in full force and
effect, and Lessor shall proceed to make such investigation and remediation as
soon as reasonably possible after the required funds are available. If Lessee
does not give such notice and provide the required funds or assurance thereof
within the time period specified above, this Lease shall terminate as of the
date specified in Lessor's notice of termination.

         9.8. TERMINATION - ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to this Paragraph 9, Lessor shall return to Lessee any advance payment
made by Lessee to Lessor and so much of Lessee's Security Deposit as has not
been, or is not then required to be, used by Lessor under the terms of this
Lease.

         9.9. WAIVER OF STATUTES. Lessor and Lessee agree that the terms of this
Lease shall govern the effect of any damage to or destruction of the Premises
and the Building with respect 

                                       20
<PAGE>
 
to the termination of this Lease and hereby waive the provisions of any present
or future statute to the extent it is inconsistent herewith.

10.      REAL PROPERTY TAXES.

         10.1. PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, as
defined in Paragraph 10.2, applicable to the Industrial Center, and except as
otherwise provided in provided in Paragraph 10.3, any such amounts shall be
included in the calculation of Common Area Operating Expenses in accordance with
the provisions of Paragraph 4.2

         10.2. REAL PROPERTY TAX DEFINITION. As used herein, the term "Real
Property Taxes" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Industrial Center by any
authority having the direct or indirect power to tax, including any city, state
or federal government, or any school, agricultural, sanitary, fire, street,
drainage, or other improvement district thereof, levied against any legal or
equitable interest of Lessor in the Industrial Center or any portion thereof,
Lessor's right to rent or other income therefrom, and/or Lessor's business of
leasing the Premises. The term "REAL PROPERTY TAXES" shall also include any tax,
fee, levy, assessment or charge, or any increase therein, imposed by reason of
events occurring, or changes in Applicable Law taking effect, during the term of
this Lease, including but not limited to a change in the ownership of the
Industrial Center or in the Improvements thereon, the execution of this Lease,
or any modification, amendment or transfer thereof, and whether or not
contemplated by the Parties. In calculating Real Property Taxes for any calendar
year, the Real Property Taxes for any real estate tax year shall be included in
the calculation of Real Property Taxes for such calendar year based upon the
number of days which such calendar year and tax year have in common.

         10.3. ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses shall not
include Real Property Taxes specified in the tax assessor's records and work
sheets as being caused by additional improvements placed upon the Industrial
Center by other lessees or Lessor for the exclusive enjoyment of such other
lessees. Notwithstanding Paragraph 10.1 hereof, Lessee shall, however, pay to
Lessor at the time Common Area Operating Expenses are payable under Paragraph
4.2, the entirety of any increase in Real Property Taxes if assessed solely by
reason of Alterations, Trade Fixtures or Utility Installations placed upon the
Premises by Lessee or at Lessee's request.

         10.4. JOINT ASSESSMENT. If the Building is not separately assessed,
Real Property Taxes allocated to the Building shall be an equitable proportion
of the Real Property Taxes for all of the land and improvements included within
the tax parcel assessed, such proportion to be determined by Lessor from the
respective valuations assigned in the assessor's work sheets or such other
information as may be reasonably available. Lessor's reasonable determination
thereof, in good faith, shall be conclusive.

         10.5. LESSEE'S PROPERTY TAXES. Lessee shall pay prior to delinquency
all taxes assessed against and levied upon Lessee-Owned Alterations and Utility
Installations, Trade 

                                       21
<PAGE>
 
Fixtures, furnishings, equipment and all personal property of Lessee contained
in the Premises or stored within the Industrial Center. When possible, Lessee
shall cause its Lessee-Owned Alterations and Utility Installations, Trade
Fixtures, furnishings, equipment and all other personal property to be assessed
and billed separately from the real property of Lessor. If any of Lessee's said
property shall be assessed with Lessor's real property, Lessee shall pay Lessor
the taxes attributable to Lessee's property within ten (10) days after receipt
of a written statement setting forth the taxes applicable to Lessee's property.

11.      UTILITIES.

                  Lessee shall pay directly for all utilities and services
supplied to the Premises, including but not limited to electricity, telephone,
security, gas and cleaning of the Premises, together with any taxes thereon. If
any such utilities or services are not separately metered to the Premises or
separately billed to the Premises, Lessee shall pay to Lessor a reasonable
proportion to be determined by Lessor of all such charges jointly metered or
billed with other premises in the Building, in the manner and within the time
periods set forth in Paragraph 4.2(d).

12.      ASSIGNMENT AND SUBLETTING.

         12.1.    LESSOR'S CONSENT REQUIRED.

                  (a) Lessee shall not voluntarily or by operation of law
assign, transfer, mortgage or otherwise transfer or encumber (collectively,
"assign") or sublease any part of Lessee's interests in this Lease or in the
Premises without Lessor's prior written consent given under the subject to the
terms of Paragraph 36.

                  (b) A change in the control of Lessee shall constitute an
assignment requiring Lessor's consent. The transfer, on a cumulative basis, of
twenty-five percent (25%) or more of the voting control of Lessee shall
constitute a change in control for this purpose.

                  (c) The involvement of Lessee or its assets in any
transaction, or series of transactions (by way of merger, sale, acquisition,
financing, refinancing, transfer, leveraged buy-out or otherwise), whether or
not a formal assignment or hypothecation of this Lease or Lessee's assets
occurs, which results or will result in a reduction of the Net Worth of Lessee,
as hereinafter defined, by an amount equal to or greater than twenty-five
percent (25%) of such Net Worth of Lessee as it was represented to Lessor at the
time of full execution and delivery of this Lease or at the time of the most
recent assignment to which Lessor has consented, or as it exists immediately
prior to said transaction or transactions constituting such reduction, at
whichever time said Net Worth of Lessees was or is greater, shall be considered
an assignment of this Lease by Lessee to which Lessor may reasonably withhold
its consent. "Net Worth Of Lessee" for purposes of this Lease shall be the net
worth of Lessee (excluding any Guarantors) established under generally accepted
accounting principles consistently applied.

                  (d) An assignment or subletting of Lessee's interest in this
Lease without Lessor's specific prior written consent shall, at Lessor's option,
be a Default curable after notice per Paragraph 13.1, or a non-curable Breach
without the necessity of any police and grace period. 

                                       22
<PAGE>
 
If Lessor elects to treat such unconsented to assignment or subletting as a non-
curable Breach, Lessor shall have the right to either: (i) terminate this Lease,
or (ii) upon thirty (30) days' written notice ("Lessor's Notice"), increase the
monthly Base Rent for the Premises to the greater of the then fair market rental
value of the Premises, as reasonably determined by Lessor, or one hundred ten
percent (110%) of the Base Rent then in effect. Pending determination of the new
fair market rental value, if disputed by Lessee, Lessee shall pay the amount set
forth in Lessor's Notice, with any overpayment credited against the next
installment(s) of Base Rent coming due, and any underpayment for the period
retroactively to the effective date of the adjustment being due and payable
immediately upon the determination thereof. Further, in the event of such Breach
and rental adjustment, (i) the purchase price of any option to purchase the
Premises hold by Lessee shall be subject to similar adjustment to the then fair
market value as reasonably determined by Lessor (without the Lease being
considered an encumbrance or any deduction for depreciation or obsolescence, and
considering the Premises at its highest and best use and in good condition) or
one hundred ten percent (110%) of the price previously in effect, (ii) any 
index-oriented rental or price adjustment formulas contained in this Lease shall
be adjusted to require that the base index be determined with reference to the
index applicable to the time of such adjustment, and (iii) any fixed rental
adjustments scheduled during the remainder of the Lease term shall be increased
in the same ratio as the new rental bears to the Base Rent in effect immediately
prior to the adjustment specified in Lessor's Notice.

                  (e) Lessee's remedy for any breach of this Paragraph 12.1 by
Lessor shall be limited to compensatory damages and/or injunctive relief.

         12.2.    TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

                  (a) Regardless of Lessor's consent, any assignment or
subletting shall not (i) be effective without the express written assumption by
such assignee or sublessee of the obligations of Lessee under this Lease, (ii)
release Lessee of any obligations hereunder, nor (iii) alter the primary
liability of Lessee for the payment of Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

                  (b) Lessor may accept any rent or performance of Lessee's
obligations from any person other than Lessee pending approval or disapproval of
an assignment. Neither a delay in the approval or disapproval of such assignment
nor the acceptance of any rent for performance shall constitute a waiver or
estoppel of Lessor's right to exercise its remedies for the Default or Breach by
Lessee of any of the terms, covenants or conditions of this Lease.

                  (c) The consent of Lessor to any assignment or subletting
shall not constitute a consent to any subsequent assignment or subletting by
Lessee or to any subsequent or successive assignment or subletting by the
assignee or sublessee. However, Lessor may consent to subsequent sublettings and
assignments of the sublease or any amendments or modifications thereto without
notifying Lessee or anyone else liable under this Lease or the sublease and
without obtaining their consent, and such action shall not relieve such persons
from liability under this Lease or the sublease.

                                       23
<PAGE>
 
                  (d) In the event of any Default or Breach of Lessee's
obligation under this Lease, Lessor may proceed directly against Lessee, any
Guarantors or anyone else responsible for the performance of the Lessee's
obligations under this Lease, including any sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor.

                  (e) Each request for consent to an assignment or subletting
shall be in writing, accompanied by information relevant to Lessor's
determination as to the financial and operational responsibility and
appropriateness of the proposed assignee or sublessee, including but not limited
to the intended use and/or required modification of the Premises, if any,
together with a non-refundable deposit of $1,000 or ten percent (10%) of the
monthly Base Rent applicable to the portion of the Premises which is the subject
of the proposed assignment or sublease, whichever is greater, as reasonable
consideration for Lessor's considering and processing the request for consent.
Lessee agrees to provide Lessor with such other or additional information and/or
documentation as may be reasonably requested by Lessor.

                  (f) Any assignee of, or sublessee under this Lease shall, be
reason of accepting such assignment or entering into such sublease, be deemed,
for the benefit of Lessor, to have assumed and agreed to conform and comply with
each and every term, covenant, condition and obligation herein to be observed or
performed by Lessee during the term of said assignment or sublease, other than
such obligations as are contrary to or inconsistent with provisions of an
assignment or sublease to which Lessor has specifically consented in writing.

                  (g) The occurrence of a transaction described Paragraph
12.2(c) shall give Lessor the right (but not the obligation) to require that the
Security Deposit be increased by an amount equal to six (6) times the then
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the
Security Deposit increase a condition to Lessor's consent to such transaction.

                  (h) Lessor, as a condition to giving its consent to assignment
or subletting, may require that the amount and adjustment schedule of the rent
payable under this Lease be adjusted to what is then the market value and/or
adjustment schedule for property similar to the Premises as then constituted, as
obtained by Lessor.

         12.3. ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

                  (a) Lessee hereby assigns and transfers to Lessor all of
Lessee's interest in all rentals and income arising from any sublease of all or
a portion of the Premises heretofore or hereafter made by Lessee, and Lessor may
collect such rent and income and apply same toward Lessee's obligations under
this Lease; provided, however, that until a Breach (as defined in Paragraph
13.1) shall occur in the performance of Lessee's obligations under this Lease,
Lessee may, except as otherwise provided in this Lease, receive, collect and
enjoy the rents accruing under such sublease. Lessor shall not, by reason of the
foregoing provision or any other 

                                       24
<PAGE>
 
assignment of such sublease to Lessor, nor by reason of the collection of the
rents from a sublease, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such Sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a Breach
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents and other charges due and to become due under the sublease.
Sublessee shall rely upon any such statement and request from Lessor and shall
pay such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right to claim against
such sublessee, or, until the Breach has been cured, against Lessor, for any
such rents and other charges so paid by said sublessee to Lessor.

                  (b) In the event of a Breach by Lessee in the performance of
its obligations under this Lease, Lessor, at its option and without any
obligation to do so, may require any sublessee to attorn to Lessor, in which
event Lessor shall undertake the obligations of the sublessor under such
sublease from the time of the exercise of said option to the expiration of such
sublease; provided, however, Lessor shall not be liable for any prepaid rents or
security deposit paid by such sublessee to such sublessor or for any other prior
defaults or breaches of such sublessor under such sublease.

                  (c) Any matter or thing requiring the consent of the sublessor
under a sublease shall also require the consent of Lessor herein.

                  (d) No sublessee under a sublease approved by Lessor shall
further assign or sublet all or any part of the Premises without Lessor's prior
written consent.

                  (e) Lessor shall deliver a copy of any notice of Default or
Breach by Lessee to the sublessee, who shall have the right to cure the Default
of Lessee within the grace period, if any, specified in such notice. The
sublessee shall have a right of reimbursement and offset from and against Lessee
for any such Defaults cured by the sublessee.

13.      DEFAULT; BREACH; REMEDIES.

         13.1. DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said default. A "Default" by Lessee is
defined as a failure by Lessee to observe, comply with or perform any of the
terms, covenants, conditions or rules applicable to Lessee under this Lease. A
"Breach" by Lessee is defined as the occurrence of one or more of the following
Defaults, and, where a grace period for cure after notice is specified herein,
the failure by Lessee to cure such Default prior to the expiration of the
applicable grace period, and shall entitle Lessor to pursue the remedies set
forth in Paragraphs 13.2 and/or 13.3:

                                       25
<PAGE>
 
                  (a) The vacating of the Premises without the intention to
reoccupy same, or the abandonment of the Premises.

                  (b) Except as expressly otherwise provided in this Lease, the
failure by Lessee to make any payment of Base Rent, Lessee's Share of Common
Area Operating Expenses, or any other monetary payment required to be made by
Lessee hereunder as and when due, the failure by Lessee to provide Lessor with
reasonable evidence of insurance or surety bond required under this Lease, or
the failure of Lessee to fulfill any obligation under this Lease which endangers
or threatens life or property, where such failure continues for a period of
three (3) days following written notice thereof by or on behalf of Lessor to
Lessee.

                  (c) Except as expressly otherwise provided in this Lease, the
failure by Lessee to provide Lessor with reasonable written evidence (in duly
executed original form, if applicable) of (i) compliance with Applicable
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service
contracts required under Paragraph 7.1(b), (iii) the rescission of an
unauthorized assignment or subletting per Paragraph 12.1, (iv) a Tenancy
Statement per Paragraphs 16 or 37, (v) the subordination or non-subordination of
this Lease per Paragraph 30, (vi) the guaranty of the performance of Lessee's
obligations under this Lease if required under Paragraphs 1.11 and 37, (vii) the
execution of any document requested under Paragraph 42 (easements), or (viii)
any other documentation or information which Lessor may reasonably require of
Lessee under the terms of this lease, where any such failure continues for a
period of ten (10) days following written notice by or on behalf of Lessor to
Lessor.

                  (d) A Default by Lessee as to the terms, covenants, conditions
or provisions of this Lease, or of the rules adopted under Paragraph 40 hereof
that are to be observed, complied with or performed by Lessee, other than those
described in Subparagraphs 13.1(a), (b) or (c), above, where such Default
continues for a period of thirty (30) days after written notice thereof by or on
behalf of Lessor to Lessee; provided; however, that if the nature of Lessee's
Default is such that more than thirty (30) days are reasonably required for its
cure, then it shall not be deemed to be a Breach of this Lease by Lessee if
Lessee commences such cure within said thirty (30) day period and thereafter
diligently prosecutes such cure to completion.

                  (e) The occurrence of any of the following events: (i) the
making by Lessee of any general arrangement or assignment for the benefit of
creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code Section
101 or any successor statue thereto (unless, in the case of a petition filed
against Lessee, the same is dismissed within sixty (60) days); (iii) the
appointment of a trustee or receiver to take possession of substantially all of
Lessee's assets located at the Premises or of Lessee's interest in this Lease,
where possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; provided, however, in the
event that any provision of this Subparagraph 13.1(e) is contrary to any
applicable law, such provision shall be of no force or effect, and shall not
effect the validity of the remaining provisions.

                                       26
<PAGE>
 
                  (f) The discovery by Lessor that any financial statement of
Lessee or of any Guarantor, given to Lessor by Lessee or any Guarantor, was
materially false.

                  (g) If the performance of Lessee's obligations under this
Lease is guaranteed; (i) the death of a Guarantor, (ii) the termination of a
Guarantor's liability with respect to this Lease other than in accordance with
the terms of such guaranty, (iii) a Guarantor's becoming insolvent or the
subject of a bankruptcy filing, (iv) a Guarantor's refusal to honor the
guaranty, or (v) a Guarantor's breach of its guaranty obligation on an
anticipatory breach basis, and Lessee's failure, within sixty (60) days
following written notice by or on behalf of Lessor to Lessee of any such event,
to provide Lessor with written alternative assurances of security, which, when
coupled with the then existing resources of Lessee, equals or exceeds the
combined financial resources of Lessee and the Guarantors that existed at the
time of execution of this Lease.

         13.2. REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), perform such duty or obligation on Lessee's
behalf, including but not limited to the obtaining of reasonably required bonds,
insurance policies or governmental licenses, permits or approvals. The costs and
expenses of any such performance by Lessor shall be due and payable by Lessee to
Lessor upon invoice therefor. If any check given to Lessor by Lessee shall not
be honored by the bank upon which it is drawn, Lessor, at its own option, may
require all future payments to be made under this Lease by Lessee to be made
only by cashier's check. In the event of a Breach of this Lease by Lessee (as
defined in Paragraph 13.1), with or without further notice or demand, and
without limiting Lessor in the exercise of any right or remedy which Lessor may
have by reason of such Breach, Lessor may:

                  (a) Terminate Lessee's right to possession of the Premises by
any lawful means, in which case this Lease and the term hereof shall terminate
and Lessee shall immediately surrender possession of the Premises to Lessor. In
such event Lessor shall be entitled to recover from Lessee: (i) the worth at the
time of the award of the unpaid rent which had been earned at the time of
terminations (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably avoided; (iii) the worth at the time of award of the amount by
which the unpaid rent for the balance of the form after the time of award
exceeds the amount of such rental loss that the Lessee proves could be
reasonably avoided; and (iv) any other amount necessary to compensate Lessor for
all the detriment proximately caused by the Lessee's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, including but not limited to the cost of recovering
possession of the Premises, expenses of reletting, including necessary
renovation and alteration of the Premises, reasonable attorneys' fees, and that
portion of any leasing commission paid by Lessor in connection with this Lease
applicable to the unexpired term of this Lease. The worth at the time of award
of the amount referred to in provision (iii) of the immediately preceding
sentence shall be computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco or the Federal Reserve Bank District
in which the Premises are located at the time of award plus one percent (1%).
Efforts by Lessor 

                                       27
<PAGE>
 
to mitigate damages caused by Lessee's Default or Breach of this Lease shall not
waive Lessor's right to recover damages under this Paragraph 13.2. If
termination of this Lease is obtained through the provisional remedy of unlawful
detainer, Lessor shall have the right to recover in such proceeding the unpaid
rent and damages as are recoverable therein, or Lessor may reserve the right to
recover all or any part thereof in a separate suite for such rent and/or
damages. If a notice and grace period required under Subparagraph 13.1(b), (c)
or (d) was not previously given, a notice to pay rent or quit, or to perform or
quit, as the case may be, given to Lessee under any statute authorizing the
forfeiture of leases for unlawful detainer shall also constitute the applicable
notice for grace period purposes required by Subparagraph 13.1(b), (c) or (d).
In such case, the applicable grace period under the unlawful detainer statute
shall run concurrently after the one such statutory notice, and the failure of
Lessee to cure the Default within the greater of the two (2) such grace periods
shall constitute both an unlawful detainer and a Breach of this Lease entitling
Lessor to the remedies provided for in this Lease and/or by said statute.

                  (b) Continue the Lease and Lessee's right to possession in
effect (in California under California Civil Code Section 1951.4) after Lessee's
Breach and recover the rent as it becomes due, provided Lessee has the right to
sublet or assign, subject only to reasonable limitations. Lessor and Lessee
agree that the limitations on assignment and subletting in this Lease are
reasonable. Acts of maintenance or preservation, efforts to relet the Premises,
or the appointment of a receiver to protect the Lessor's interest under this
Lease, shall not constitute a termination of the Lessee's right to possession.

                  (c) Pursue any other remedy now or hereafter available to
Lessor under the laws or judicial decisions of the state wherein the Premises
are located.

                  (d) The expiration or termination of this Lease and/or the
termination of Lessee's right to possession shall not relieve Lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

         13.3. INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor
for free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions" shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach (as defined in Paragraph 13.1) of this Lease by Lessee, any such
inducement Provision shall automatically be deemed deleted from this Lease and
of no further force and effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor, as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph 13.3 shall not be deemed a waiver by Lessor of the 

                                       28
<PAGE>
 
provisions of this Paragraph 13.3 unless specifically so stated in writing by
Lessor at the time of such acceptance. 

         13.4. LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of rent and other sums due hereunder will cause Lessor to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain. Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed upon
Lessor by the terms of any ground lease, mortgage or deed of trust covering the
Premises. Accordingly, if any installment of rent or other sum due from Lessor
shall not be received by Lessor or Lessor's designee within ten (10) days after
such amount shall be due, then, without any requirement for notice to Lessee,
Lessee shall pay to Lessor a late charge equal to six percent (6%) of such
overdue amount. The parties hereby agree that such late charge represents a late
and reasonable estimate of the costs Lessor will incur by reason of late payment
by Lessee. Acceptance of such late charge by Lessor shall in no event constitute
a waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder whether or not
collected for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

         13.5. BREACH BY LESSOR. Lessor shall not be deemed in breach of this
Lease unless Lessor fails within a reasonable time to perform an obligation
required to be performed by Lessor. For purposes of this Paragraph 13.5, a
reasonable time shall in no event be less than thirty (30) days after receipt by
Lessor, and by any Lender(s) whose name and address shall have been furnished to
Lessee in writing for such purpose, of written notice specifying wherein such
obligation of Lessor has not been performed; provided, however, that if the
nature of Lessor's obligation is such that more than thirty (30) days after such
notice are reasonably required for its performance, then Lessor shall not be in
breach of this Lease if performance is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

14.      CONDEMNATION.

               If the Premises or any portion thereof are taken under the power
of eminent domain or sold under the threat of the exercise of said power (all of
which are herein called "condemnation"), this Lease shall terminate as to the
part so taken as of the date the condemning authority takes title or possession,
whichever first occurs. If more than ten percent (10%) of the floor area of the
Premises, or more than twenty five percent (25%) of the portion of the Common
Areas designated for Lessee's parking, is taken by condemnation, Lessee may, at
Lessee's option, to be exercised in writing within ten (10) days after Lessor
shall have given Lessee written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession) terminate this Lease as of the date the condemning authority takes
such possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and affect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in the same
proportion as the rentable floor area of the Premises taken bears to the total
rentable floor area of the Premises. No 

                                       29
<PAGE>
 
reduction of Base Rent shall occur if the condemnation does not apply to any
portion of the Premises. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution of value of the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessor
shall be entitled to any compensation, separately awarded to Lessee for Lessee's
relocation expenses and/or loss of Lessee's Trade Fixtures. In the event that
this Lease is not terminated by reason of such condemnation, Lessor shall to the
extent of its net severance damages received, over and above Lessee's Share of
the legal and other expenses incurred by Lessor in the condemnation matter,
repair any damage to the Premises caused by such condemnation authority. Lessor
shall be responsible for the payment of any amount in excess of such net
severance damages required to complete such repair.

15.      BROKER'S FEES.

         15.1.      PROCURING CAUSE. The Broker(s) named in Paragraph 1.10
is/are the procuring cause of this Lease.

         15.2.      ASSUMPTION OF OBLIGATIONS. Any buyer or transferee of
Lessor's interest in this Lease, whether such transfer is by agreement or by
operation of law shall be deemed to have assumed Lessor's obligation under this
Paragraph 15. Each Broker shall be an intended third party beneficiary of the
provisions of Paragraph 1.10 and of this Paragraph 15 to the extent of its
interest in any commission arising from this Lease and may enforce that right
directly against Lessor and its successors.

         15.3.      REPRESENTATIONS AND WARRANTEE. Lessee and Lessor each
represent and warrant to the other that it has had no dealings with any person,
firm, broker or finder other than as named in Paragraph 1.10(a) in connection
with the negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fee in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnify, protect, defend and hold the other harmless from and against
liability for compensation or charges which may be claimed by any such unnamed
broker, finder or other similar party by reason of any dealings or actions of
the indemnifying Party, including any costs, expenses, and/or attorneys' fees
reasonably incurred with respect therein.

16.      TENANCY AND FINANCIAL STATEMENTS.

         16.1.      TENANCY STATEMENT. Each party (as "Responding Party") shall
within ten (10) days after written notice from the other Party (the "Requesting
Party") execute, acknowledge and deliver to the Requesting Party a statement in
writing in a form similar to the then most current "Tenancy Statement" form
published by the American Industrial Real Estate Association, plus such
additional information, confirmation and/or statements as may be reasonably
requested by the Requesting Party.

                                       30
<PAGE>
 
     16.2.     FINANCIAL STATEMENT. If Lessee desires to finance, refinance, or
sell the Premises or the Building, or any part thereof, Lessee and all
Guarantors shall deliver to any potential lender or purchaser designated by
Lessor such financial statements of Lessee and such Guarantors as may be
reasonably required by such lender or purchaser, including but not limited to
Lessee's financial statements for the past three (3) years. All such financial
statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17.  LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean the owner
or owners at the time in question of the fee title to the Premises. In the event
of a transfer of Lessor's title or interest in the Premises or in the Lease,
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in Paragraph 15.3, upon such transfer or
assignment and delivery of the Security Deposit, as aforesaid, the prior Lessor
shall be relieved of all liability with respect to the obligations and/or
covenants under the Lease thereafter to be performed by the Lessor. Subject to
the foregoing, the obligations and/or covenants in this Lease to be performed by
the Lessor shall be binding only upon the Lessor as hereinabove defined.

18.  SEVERABILITY. The invalidity of any provision of this Lease, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19.  INTEREST ON PAST DUE OBLIGATIONS. Any monetary payment due Lessor
hereunder, other than late charges, not received by Lessor within ten (10) days
following the date on which it was due, shall bear interest from the date due at
the prime rate charged by the largest state chartered bank in the state in which
the Premises are located plus four percent (4%) per annum, but not exceeding the
maximum rate allowed by law, in addition to the potential late charge provided
for in Paragraph 13.4.

20.  TIME OF ESSENCE. Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

21.  RENT DEFINED All monetary obligations of Lessee to Lessor under the terms
of this Lease are deemed to be rent.

22.  NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement understanding shall be effective.
Lesser and Lessor each represents and warrants to the Broker that it has made,
and is relying safely upon, its own investigation as to the nature, quality,
character and financial responsibility with respect thereto or with respect to
any default or breach hereof by either Party. Each Broker shall be an intended
third party beneficiary of the provisions of this Paragraph 22.

23.  NOTICES.

     23.1.     NOTICE REQUIREMENTS. All notices required or permitted by this
Lease shall be in writing and may be delivered in person (by hand or by
messenger or courier service) or may be 

                                       31
<PAGE>
 
sent by regular, certified or registered mail or U.S. Postal Service Express
Mail, with postage prepaid, or by facsimile transmission during normal business
hours, and shall be deemed sufficiently given if served in a manner specified in
this Paragraph 23. The addresses noted adjacent to a Party's signature on this
Lease shall be the Party's address for delivery or mailing of notice purposes.
Either Party may by written notice to the other specify a different address for
notice purposes, except that upon Lessee's taking of the Premises, the Premises
shall constitute Lessee's address for the purpose of mailing or delivering
notices to Lessee. A copy of the notices required or permitted to be given to
Lessor hereunder shall be concurrently transmitted to such party or parties at
such addresses as Lessor may from time to time hereafter designated by written
notice to Lessee.

     23.2. DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given forty eight (48) hours after
the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantees next day delivery shall be deemed given twenty four (24) hours after
delivery of the same to the United States Postal Service or courier. If any
notice is transmitted by facsimile transmission or similar means, the same shall
be deemed served or delivered up telephone or facsimile confirmation or receipt
of the transmission thereof, provided a copy is also delivered via delivery or
mail. If notice is received on a Saturday or a Sunday or a legal holiday, it
shall be deemed received on the next business day.

24.  WAIVERS. No waiver by Lessor of the Default or Breach of any term, covenant
or condition hereof by Lessee, shall be deemed in waiver of any other term,
covenant or condition hereof, or of any subsequent Default or Breach by Lessee
of the same or any other term, covenant or condition hereof. Lessor's consent
to, or approval of, any such act shall not be deemed to render unnecessary the
obtaining of Lessor's consent to, or approval of, any subsequent or similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provisions
of this Lease requiring such consent. Regardless of Lessor's knowledge of a
Default or Breach at the time of accepting rent, the acceptance of rent by
Lessor shall not be a waiver of any Default or Breach by Lessee of any provision
hereof. Any payment given Lessor by Lessee may be accepted by Lessor on account
of moneys or damages due Lessor, notwithstanding any qualifying statements or
conditions made by Lessee in connection therewith, which such statements and/or
conditions shall be no force or effect whatsoever unless specifically agreed to
in writing by Lessor at or before the time of deposit of such payment.

25.  RECORDING. Either Lessor or Lessee shall, upon request of the other ,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes. The party requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

26.  NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease. In the event that Lessee holds over in violation of this Paragraph
26 then the Base Rent payable from and after the time of 

                                       32
<PAGE>
 
the expiration or earlier termination this Lease shall be increased to two
hundred percent (200%) of the Base Rent applicable during the month immediately
proceeding such expiration or earlier termination. Nothing contained herein
shall be counted as a consent by Lessor to any holding over by Lessee.

27.  CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, whereover possible, be cumulative with all other remedies
at law or in equity.

28.  COVENANTS AND CONDITIONS. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

29.  BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the
Parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located. Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

30.  SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

          30.1.  Subordination. This Lease and any Option granted hereby shall
be subject and subordinate to any ground lease, mortgage, deed of trust, or
other hypothecation or security device (collectively, "Security Device"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default pursuant
to Paragraph 13.5. If any Lender shall elect to have this Lease and/or any
Option granted hereby superior to the lien of its Security Device and shall
given written notice thereof to Lessee, this Lease and such Options shall be
deemed prior to such Security Device, notwithstanding the relative dates of the
documentation or recordation thereof.

          30.2.  Attornment. Subject to the non-disturbance provisions of
Paragraph 30.3, Lessee agrees to attorn to a Lender or any other party who
acquires ownership of the Premises by reason of the foreclosure of a Security
Device, that in the event of such foreclosure, such new owner shall not: (i) be
liable for any act or omission of any prior lessor or with respect to events
occurring prior to acquisitions of ownership, (ii) be subject to any offsets or
defenses which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one month's rent.

          30.3   Non-Disturbance. With respect to Security Devices entered into
by Lessor after the execution of this lease, Lessee's subordination of this
Lease shall be subject to receiving assurance (a "non disturbance agreement")
from the Lender that Lessor's possession and this Lease, including any options
to extend the term hereof, will not be disturbed so long as Lessee is not in
Breach hereof and attorns to the record owner of the Premises.

                                       33
<PAGE>
 
       30.4   Self-Executing. The agreements contained in this Paragraph 30
shall be effective without the execution of any further documents; provided,
however, that upon written request from Lessor or a Lender in connection with a
sale, financing or refinancing of Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required in separately document any such
subordination or non subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31.    ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding,
action, or appeal thereon, shall be entitled to reasonable attorneys' fees. Such
fees may be awarded in the same suit or recovered in a separate suit, whether or
not such action or proceeding is pursued in decision or judgment. The term
"PREVAILING PARTY" shall include, without limitation, a Party or Broker who
substantially obtains or defeats the relief sought, as the case may be, whether
by compromise, settlement, judgment, or the abandonment by the other Party or
Broker of its claim or defense. The attorneys' fee award shall not be computed
in accordance with any court fee schedule, but shall be such as to fully
reimburse all attorneys' fees reasonably incurred. Lessor shall be entitled to
attorneys' fees, costs and expenses incurred in preparation and service of
notices of Default and consultation in connection therewith, whether or not a
legal action is subsequently commenced in connection with such Default or
resulting Breach. Broker(s) shall be intended third party beneficiaries of the
Paragraph 31.

32.    LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the Building, as Lessor
may reasonably deem necessary. Lessor may at any time place on or about the
Premises or Building any ordinary "For Sale" signs and Lessor may at any time
during the last one hundred eighty (180) days of the term hereof place on or
about the Premises any ordinary "For Lease" signs. All such activities of Lessor
shall be without abatement of rent or liability to Lessee.

33.    AUCTIONS. Lessor shall not conduct, or permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent. Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34.    SIGNS. Lessee shall not place any sign upon the exterior of the Premises
or the Building, except that Lessee may, with Lessor's prior written consent,
install (but not on the roof) such signs as are reasonably required to advertise
Lessee's own business so long as such signs are in a location designated by
Lessor and comply with Applicable Requirements and the signage criteria
established for the Industrial Center by Lessor. The installation of any sign on
the Premises by or for Lessee shall be subject to the provisions of Paragraph 7
(Maintenance, Repairs, Utility Installation, Trade Fixtures and Alterations).
Unless otherwise expressly agreed herein, Lessor 

                                       34
<PAGE>
 
reserves all rights to the use of the roof of the Building, and to the right to
install advertising signs on the Building, including the roof, which do not
unreasonably interfere with the conduct of Lessee's business; Lessor shall be
entitled to all revenues from such advertising signs.

35.  TERMINATION; MERGER. Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Broach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, Lesser shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of the
existing subtenancies. Lessor's failure within ten (10) days following any such
event to make a written election to the contrary by written notice to the holder
or any such lessor interest, shall constitute Lessor's election to have such
event constitute the termination of such interest.

36.  CONSENTS.

              (a) Except for Paragraph 33 hereof (Auctions) or as otherwise
provided herein, wherever in this Lease the consent of a Party is required to an
act by or for the other Party, such consent shall not be unreasonably withhold
or delayed. Lessor's actual reasonable costs and expenses (including but not
limited to architects', attorneys', engineers' and other consultants' fees)
incurred in the consideration, of, or response to, a request by Lessee for any
Lessor consent pertaining to this Lease or the Premises, including but not
limited to consents to an assignment a subletting or the presence or use of a
Hazardous Substance, shall be paid by Lessee to Lessor upon receipt of an
invoice and supporting documentation therefor. In addition to the deposit
described in Paragraph 12.2(e), Lessor may, as a condition to conserving any
such request by Lessee, require that Lessee deposit with Lessor an amount of
money (in addition to the Security Deposit held under Paragraph 5) reasonably
calculated by Lessor to represent the cost Lessor will incur in considering and
responding to Lessee's request. Any unused portion of said deposit shall be
refunded to Lessee without interest. Lessor's consent to any act, assignment of
this Lease or subletting of the Premises by Lessee shall not constitute an
acknowledgment that no Default or Breach by Lessee of this Lease exists, nor
shall such consent be deemed a waiver of any then existing Default or Breach,
except as may be otherwise specifically stated in writing by Lessor at the time
of such consent.

              (b) All conditions to Lessor's consent authorized by this Lease
are acknowledge by Lessee as being reasonable. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the impositions by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular matter for which consent is being
given.

37.  GUARANTOR.

     37.1.    Form of Guaranty. If there are to be any Guarantors of this Lease
per Paragraph 1.11, the form of the guaranty to be executed by each such
Guarantor shall be in the form most recently published by the American
Industrial Real Estate Association, and each such Guarantor shall have the same
obligations as Lessee under this lease, including but not limited to the
obligation to provide the Tenancy Statement and information required in
Paragraph 16.

                                       35
<PAGE>
 
     37.2. Additional Obligations of Guarantor. It shall constitute a Default of
the Lessee under this Lease if any such Guarantor fails or refuses, upon
reasonable request by Lessor to give: (a) evidence of the due execution of the
guaranty called for by this Lease, including the authority of the Guarantor (and
of the party signing on Guarantor's behalf) to obligate such Guarantor on said
guaranty, and resolution of its board of directors authorizing the making of
such guaranty, together with a certificate of incumbency showing the signatures
of the persons authorized to sign on its behalf, (b) current financial
statements of Guarantor as may from time to time be requested by Lessor, (c) a

     39.2. Options Personal to Original Lessee. Each Option granted to Lessee in

and cannot be voluntarily or involuntarily assigned or exercised by any person
or entity other than said original Lessee while the original Lessee is in full
and actual possession of the Premises and without the intention of thereafter
assigning or subletting. The Options, if any, herein granted to Lessee are not
assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

     39.3. Multiple Options. In the event that Lessee has any multiple
Options to extend or renew this Lease, a later option cannot be exercised unless
the prior Options to extend or renew this Lease have been validly exercised.

           (a) Lessee shall have no right to exercise an Option, notwithstanding
any provision in the grant of Option to the contrary; (i) during the period
commencing with the giving of any notice of Default under Paragraph 13.1 and
continuing until the noticed Default is cured, or (ii) during the period of time
any monetary obligation due Lessor from Lessee is unpaid (without regard to
whether notice thereof is given Lessee), or (iii) during the time Lessee is in

Breach of this Lease, or (iv) in the event that Lessor has given to Lessee three
(3) or more notices of separate Defaults under Paragraph 13.1 during the twelve
(12) month period immediately preceding the exercise of the Option, whether or
not the Defaults are cured.

          (b) The period of time within which an Option may be exercised shall
not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of Paragraph 39.4(a).

          (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to lessor a monetary obligation of Lessee
for a period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessor gives to
Lessee three (3) or more notices of separate Defaults under Paragraph 13.1
during any twelve (12) month period, whether or not the Defaults are cured, or
(iii) if Lessee commits a Breach of this Lease.

tenants of the Building and the Industrial Center and their invitees.

41.  SECURITY MEASURES. Lessee hereby acknowledges that the rental payable to

without the consent of joinder of Lessee, such easements, rights of way, utility
raceways, and dedications that Lessor deems necessary, and to cause the
recordation of patent maps and restrictions, so long as such easements, rights
of way, utility raceways, dedications, maps and restrictions do not reasonably
interfere with the use of the Premises by Lessee. Lessee agrees to sign any
documents reasonably requested by Lessor to effectuate any such easement rights,
dedication, map or restrictions.

43.  PERFORMANCE UNDER PROTEST. If at any time a dispute may arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suit for recovery of such sum. If it shall be adjudged
that there was no logical obligation on the part of said Party to pay such sum
or any part thereof, said Party shall be entitled to recover such sum or so much
thereof as it was not legally required to pay under the provisions of this

Mr. Glenn English

Re:  10461 Old Placerville Road, Ste. 130
     ------------------------------------

We propose to complete the tenant improvements in above unit according to the
plans we have to date, and according to the breakdown sheet which will accompany
this proposal. The only variables I am aware of at this point are as follows:

1).  We have allowed $2500 to cover the costs of the permits and the costs of
     having the plans drawn and made ready for the county.

2).  We have made provision for 30 new electrical circuits in the new sub panel,
     but are only including in the price of the improvements 18 of those
     circuits, which were given to us originally by Jim. Because we do not know
     the exact location of the remaining 5 circuits, they will be priced
     directly to Jim when they decide the exact locations.

By signing below, you are accepting this proposal in the amount of $62,494 for
the improvements to this space. A detailed list on the next page will, show you
a breakdown of the different areas and the amounts each of them as per bid.

connection therewith. The Premises, the Building, the Common Areas, the land
upon which the same are located, along with all other buildings and improvements

monthly parking as set by Lessor and/or its licensee. See paragraph 2.2 of the
attached Addendum.

          2.2.1. If Lessee commits, permits or allows any of the prohibited
activities described in the Lease or the rules then in effect, then Lessor shall
have the right, without notice, in addition to such other rights and remedies
that it may have, to remove or tow away the vehicle involved and charge the cost
to Lessee, which cost shall be immediately payable upon demand by Lessor.

          2.2.2. The monthly parking rate per parking space will be $0.00
per month at the commencement of the term of this Lease, and is subject to
change upon five (5) days prior written notice to Lessee. Monthly parking fees
shall be payable one month in advance prior to the first day of each calendar
month.

     2.3. COMMON AREAS-DEFINITION. The term "Common Areas" is defined as all
areas and facilities outside the Premises and within the exterior boundary line
of the Office Building Project that are provided and designated by the Lessor
from time to time for the general non-exclusive use of Lessor, Lessee and of the

<PAGE>
 
responsible to Lessee for the noncompliance with said rules and regulations by
other lessees, their agents, employees and invitees of the Office Building
Project.

3.   TERM.

     3.1. TERM. The term and Commencement Date of this Lease shall be as
specified in paragraph 1.5 of the Basic Lease Provisions.

     3.2. DELAY IN POSSESSION. Notwithstanding said Commencement Date, if for
any reason Lessor cannot deliver possession of the Premises to Lessee on said
date and subject to paragraph 3.2.2, Lessor shall not be subject to any
liability therefor, nor shall such failure affect the validity of this Lease or
the obligations of Lessee hereunder or extend the term hereof; but, in such
case, Lessee shall not be obligated to pay rent or perform any other obligation
of Lessee under the terms of this Lease, except as may be otherwise provided in
this Lease, until possession of the Premises is tendered to Lessee, as
hereinafter defined; provided, however, that if Lessor shall not have delivered
possession of the Premises within sixty (60) days following said Commencement
Date, as the same may be extended under the terms of a Work Letter

                                       3
<PAGE>
 
executed by Lessor and Lessee and failure to deliver the Premises is solely
within Lessor's control, Lessee may, at Lessee's option, by notice in writing to
Lessor within ten (10) days thereafter, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided, however,
that as to Lessee's obligations, Lessee first reimburses Lessor for all costs
incurred for Non-Standard Improvements and, as to Lessor's obligations, Lessor
shall return any money previously deposited by Lessee (less any offsets due
Lessor for Non-Standard Improvements), and provided further, that if such
written notice by Lessee is not received by Lessor within said ten (10) day
period, Lessee's right to cancel this Lease hereunder shall terminate and be of
no further force or effect.

          3.2.1. Possession Tendered-Defined. Possession of the Premises shall
be deemed tendered to Lessee ("Tender of Possession") when (1) the improvements
to be provided by Lessor under this Lease are substantially completed; (2) the
Building utilities are ready for use in the Premises; (3) Lessee has reasonable
access to the Premises and (4) ten (10) days shall have expired following
advance written notice to Lessee of the occurrence of the matters described in
(1), (2) and (3), above of this paragraph 3.2.1.

          3.2.2. Delays Caused by Lessee. There shall be no abatement of rent,
and the sixty (60) days period following the Commencement Date before which
Lessee's right to cancel this Lease accrues under paragraph 3.2, shall be deemed
extended to the extent of any delays caused by acts or omissions of Lessee,
Lessee's agents, employees and contractors.

     3.3. EARLY POSSESSION. If Lessee occupies the Premises prior to said
Commencement Date, such occupancy shall be subject to all provisions of this
Lease, such occupancy shall not change the termination date, and Lessee shall
pay rent for such occupancy.

     3.4. Uncertain Commencement. In the event commencement of the Lease term is
defined as the completion of the improvements, Lessee and Lessor shall execute
an amendment to this Lease establishing the date of Tender of Possession (as
defined in paragraph 3.2.1) or the actual taking of possession by Lessee,
whichever first occurs, as the Commencement Date.

4.   RENT.

     4.1. BASE RENT. Subject to adjustment as hereinafter provided in paragraph
4.3 and except as may be otherwise expressly provided in this Lease, Lessee
shall pay to Lessor the Base Rent for the Premises set forth in paragraph 1.6 of
the Basic Lease Provisions, without offset or deduction. Lessee shall pay Lessor
upon execution hereof the advance Base Rent described in paragraph 1.8 of the
Basic Lease Provisions. Rent for any period during the term hereof which is for
less than one month shall be prorated based upon the actual number of days of
the calendar month involved. Rent shall be payable in lawful money of the United
States to Lessor at the address stated herein or to such other persons or at
such other places as Lessor may designate in writing. See Paragraph 4.2 of the
attached Addendum.

     4.2. OPERATING EXPENSE INCREASE. Lessee shall pay to Lessor during the term
hereof, in addition to the Base Rent, Lessee's Share, as hereinafter defined, of
the amount by which all Operating Expenses, as hereinafter defined, for each
Comparison Year exceeds the amount of all

                                       4
<PAGE>
 
Operating Expenses for the Base Year, such excess being hereinafter referred to
as the "Operating Expense Increase," in accordance with the following
provisions:

          (a) "Lessee's Share" is defined, for purposes of this Lease, as the
percentage set forth in paragraph 1.10 of the Basic Lease Provisions, which
percentage has been determined by dividing the approximate square footage of the
Premises by the total approximate square footage of the rentable space contained
in the Office Building Project. It is understood and agreed that the square
footage figures set forth in the Basic Lease Provisions are approximations which
Lessor and Lessee agree are reasonable and shall not be subject to revision
except in connection with an actual change in the size of the Premises or a
change in the space available for Lessee in the Office Building Project.

          (b) "Base Year" is defined as the calendar year in which the Lease
term commences.

          (c) "Comparison Year" is defined as each calendar year during the term
of this Lease subsequent to the Base Year; provided, however, Lessee shall have
no obligation to pay a share of the Operating Expense Increase applicable to the
first twelve (12) months of the Lease Term (other than such as are mandated by a
governmental authority, as to which government mandated expenses Lessee shall
pay Lessee's Share, notwithstanding they occur during the first twelve (12)
months). Lessee's Share of the Operating Expense Increase for the first and last
Comparison Years of the Lease Term shall be prorated according to that portion
of such Comparison Year as to which Lessee is responsible for a share of such
increase.

          (d) "Operating Expenses" is defined, for purposes of this Lease, to
include all costs, if any, incurred by Lessor in the exercise of its reasonable
discretion, for:

              (i)   The operation, repair, maintenance, and replacement, in
     neat, clean, safe, good order and condition, of the Office Building
     Project, including but not limited to, the following:

                  (aa) The Common Areas, including their surfaces, coverings,
          decorative items, carpets, drapes and window coverings, and including
          parking areas, loading and unloading areas, trash areas, roadways,
          sidewalks, walkways, stairways, parkways, driveways, landscaped areas,
          striping, bumpers, irrigation systems, Common Area lighting
          facilities, building exteriors and roofs, fences and gates:

                  (bb) All heating, air conditioning, plumbing, electrical
          systems, life safety equipment, telecommunication and other equipment
          used in common by, or for the benefit of, lessees or occupants of the
          Office Building Project, including elevators and escalators, tenant
          directories, fire detection systems including sprinkler system
          maintenance and repair.

              (ii)   Trash disposal, janitorial and security services;

                                       5
<PAGE>
 
              (iii)  Any other service to be provided by Lessor that is
     elsewhere in this Lease slated to be an "Operating Expense";

              (iv)   The cost of the premiums for the liability and property
     insurance policies to be maintained by Lessor under paragraph 8 hereof;

              (v)    The amount of the real property taxes to be paid by Lessor
     under paragraph 10.1 hereof;

              (vi)   The cost of water, sewer, gas, electricity, and other
     publicly mandated services to the Office Building Project;

              (vii)  Labor, salaries and applicable fringe benefits and costs,
     materials, supplies and tools, used in maintaining and/or cleaning the
     Office Building Project and accounting and a management fee attributable to
     the operation of the Office Building Project;

              (viii) Replacing and/or adding improvements mandated by any
     governmental agency and any repairs or removals necessitated thereby
     amortized over its useful life according to Federal income tax regulations
     or guidelines for depreciation thereof (including interest on the
     unamortized balance as is then reasonable in the judgment of Lessor's
     accountants);

              (ix)   Replacements of equipment or improvements that have a
     useful life for depreciation purposes according to Federal income tax
     guidelines of five (5) years or less, as amortized over such life.

          (e) Operating Expenses shall not include the costs of replacements of
equipment or improvements that have a useful life for Federal income tax
purposes in excess of five (5) years unless it is of the type described in
paragraph 4.2(d)(viii), in which case their cost shall be included as above
provided.

          (f) Operating Expenses shall not include any expenses paid by any
lessee directly to third parties, or as to which Lessor is otherwise reimbursed
by any third party, other tenant, or by insurance proceeds.

          (g) Lessee's Share of Operating Expense Increase shall be payable by
Lessee within ten (10) days after a reasonably detailed statement of actual
expenses is presented to Lessee by Lessor. At Lessor's option, however, an
amount may be estimated by Lessor from time to time in advance of Lessee's Share
of the Operating Expense Increase for any Comparison Year, and the same shall be
payable monthly or quarterly, as Lessor shall designate, during each Comparison
Year of the Lease term, on the same day as the Base Rent is due hereunder. In
the event that Lessee pays Lessor's estimate of Lessee's Share of Operating
Expense Increase as aforesaid, Lessor shall deliver to Lessee within sixty (60)
days after the expiration of each Comparison Year a reasonably detailed
statement showing Lessee's Share of the actual Operating Expense Increase 
incurred during such year. If Lessee's payment under this paragraph 4.2(g)
during said Comparison Year exceed Lessee's shares as indicated on said
statement, Lessee shall be entitled to credit the amount of such overpayment
against Lessee's Share of Operating Expense Increase next falling due. If
Lessee's payments under this

                                       6
<PAGE>
 
paragraph during said Comparison Year were less than Lessee's Share as indicated
on said statement, Lessee shall pay to Lessor the amount of the deficiency
within ten (10) days after delivery by Lessor to Lessee of said statement.
Lessor and Lessee shall forthwith adjust between them by cash payment any
balance determined to exist with respect to that portion of the last Comparison
Year for which Lessee is responsible as to Operating Expense Increases,
notwithstanding that the Lease term may have terminated before the end of such
Comparison Year.

5.   SECURITY DEPOSIT.

     Lessee shall deposit with Lessor upon execution hereof the security deposit
set forth in paragraph 1.9 of the Basic Lease Provisions as security for
Lessee's faithful performance of Lessee's obligations hereunder. If Lessee fails
to pay rent or other charges due hereunder, or otherwise defaults with respect
to any provision of this Lease, Lessor may use, apply or retain all or any
portion of said deposit for the payment of any rent or other charge in default
for the payment of any other sum to which Lessor may become obligated by reason
of Lessee's default, or to compensate Lessor for any loss or damage which Lessor
may suffer thereby. If Lessor so uses or applies all or any portion of said
deposit, Lessee shall within ten (10) days after written demand therefor deposit
cash with Lessor in an amount sufficient to restore said deposit to the full
amount then required of Lessee. If the monthly Base Rent shall, from time to
time, increase during the term of this Lease. Lessee shall, at the time of such
increase, deposit with Lessor additional money as a security deposit so that the
total amount of the security deposit held by Lessor shall at all times bear the
same proportion to the then current Base Rent as the initial security deposit
bears to the initial Base Rent set forth in paragraph 1.6 of the Basic Lease
Provisions. Lessor shall not be required to keep said security deposit separate
from its general accounts. If Lessee performs all of Lessee's obligations
hereunder, said deposit, or so much thereof as has not heretofore been applied
by Lessor, shall be returned, without payment of interest or other increment for
its use to Lessee (or, at Lessor's option, to the last assignee, if any, of
Lessee's interest hereunder) at the expiration of the term hereof, and after
Lessee has vacated the Premises. No trust relationship is created herein between
Lessor and Lessee with respect to said Security Deposit.

6.   USE.

     6.1. USE. The Premises shall be used and occupied only for the purpose set
forth in paragraph 1.4 of the Basic Lease Provisions or any other use which is
reasonably comparable to that use and for no other purpose.

     6.2. COMPLIANCE WITH LAW.

          (a) Lessor warrants to Lessee that the Premises, in the state existing
on the date that the Lease term commences, but without regard to alterations or
improvements made by Lessee or the use for which Lessee will occupy the
Premises, does not violate any covenants or restrictions of record, or any
applicable building code, regulation or ordinance in effect on such Lease term
Commencement Date. In the event it is determined that this warranty has been
violated, then it shall be the obligation of the Lessor, after written notice
from Lessee, to promptly, at Lessor's sole cost and expense, rectify any such
violation.

                                       7
<PAGE>
 
          (b) Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
expense, promptly comply with all applicable statutes, ordinances, rules,
regulations, orders, covenants and restrictions of record, and requirements of
any fire insurance underwriters or rating bureaus, now in effect or which may
hereafter come into effect, whether or not they reflect a change in policy from
that now existing, during the term or any part of the term hereof, relating in
any manner to the Premises and the occupation and use by Lessee of the Premises.
Lessee shall conduct its business in a lawful manner and shall not use or permit
the use of the Premises or the Common Areas in any manner that will tend to
create waste or a nuisance or shall tend to disturb other occupants of the
Office Building Project.

     6.3. CONDITION OF PREMISES.

          (a) Lessor shall deliver the Premises to Lessee in a clean condition
on the Lease Commencement Date (unless Lessee is already in possession) and
Lessor warrants to Lessee that the plumbing, lighting, air conditioning, and
heating system in the Premises shall be in good operating condition. In the
event that it is determined that this warranty has been violated, then it shall
be the obligation of Lessor, after receipt of written notice from Lessee setting
forth with specificity the nature of the violation, to promptly, at Lessor's
sole cost, rectify such violation.

          (b) Except as otherwise provided in this Lease, Lessee hereby accepts
the Premises and the Office Building Project in their condition existing as of
the Lease Commencement Date or the date that Lessee takes possession of the
Premises, whichever is earlier, subject to all applicable zoning, municipal,
county and state laws, ordinances and regulations governing and regulating the
use of the Premises, and any easements, covenants or restrictions of record, and
accepts this Lease subject thereto and to all matters disclosed thereby and by
any exhibits attached hereto. Lessee acknowledges that it has satisfied itself
by its own independent investigation that the Premises are suitable for its
intended use, and that neither Lessor nor Lessor's agent or agents has made any
representation or warranty as to the present or future suitability of the
Premises, Common Areas, or Office Building Project for the conduct of Lessee's
business.

7.   MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

     7.1. LESSOR'S OBLIGATIONS. Lessor shall keep the Office Building Project,
including the Premises, interior and exterior walls, roof, and common areas, and
the equipment whether used exclusively for the Premises or in common with other
premises, in good condition and repair; provided, however, Lessor shall not be
obligated to paint, repair or replace wall coverings, or to repair or replace
any improvements that are not ordinarily a part of the Building or are above
then Building standards. Except as provided in paragraph 9.5, there shall be no
abatement of rent or liability of Lessee on account of any injury or
interference with Lessee's business with respect to any improvements,
alterations or repairs made by Lessor to the Office Building Project or any part
thereof. Lessee expressly waives the benefits of any statute now or hereafter in
effect which would otherwise afford Lessee the right to make repairs at Lessor's

                                       8
<PAGE>
 
expense or to terminate this Lease because of Lessor's failure to keep the
Premises in good order, condition and repair.

     7.2. LESSEE'S OBLIGATIONS.

          (a) Notwithstanding Lessor's obligation to keep the Premises in good
condition and repair, Lessee shall be responsible for payment of the cost
thereof to Lessor as additional rent for that portion of the cost of any
maintenance and repair of the Premises, or any equipment (wherever located) that
serves only Lessee or the Premises, to the extent such cost is attributable to
causes beyond normal wear and tear or attributable to Lessee's negligence,
Lessee shall be responsible for the cost of painting, repairing or replacing
wall coverings, and to repair or replace any Premises improvements that are not
ordinarily a part of the Building or that are above then Building standards.
Lessor may, at its option, upon reasonable notice, elect to have Lessee perform
any particular such maintenance or repair the cost of which is otherwise
Lessee's responsibility hereunder.

          (b) On the last day of the term hereof, or on any sooner termination,
Lessee shall surrender the Premises to Lessor in the same condition as received,
ordinary wear and tear excepted, clean and free of debris. Any damage or
deterioration of the Premises shall not be deemed ordinary wear and tear if the
same could have been prevented by good maintenance practices by Lessee. Lessee
shall repair any damage to the Premises occasioned by the installation or
removal of Lessee's trade fixtures, alterations, furnishings and equipment.
Except as otherwise stated in this Lease, Lessee shall leave the air lines,
power panels, electrical distribution systems, lighting fixtures, air
conditioning, window coverings, wall coverings, carpets, wall paneling, ceilings
and plumbing on the Premises and in good operating condition.

     7.3. ALTERATIONS AND ADDITIONS.

          (a)  Lessee shall not, without Lessor's prior written consent make any
alterations, improvements, additions, Utility Installations or repairs in, on or
about the Premises, or the Office Building Project. As used in this paragraph
7.3 the term "Utility Installation" shall mean carpeting, window and wall
coverings, power panels, electrical distribution systems, lighting fixtures, air
conditioning, plumbing, and telephone and telecommunication wiring and
equipment. At the expiration of the term, Lessor may require the removal of any
or all of said alterations, improvements, additions or Utility Installations,
and the restoration of the Premises and the Office Building Project to their
prior condition, at Lessee's expense. Should Lessor permit Lessee to make its
own alterations, improvements, additions or Utility Installations, Lessee shall
use only such contractor as has been expressly approved by Lessor, and Lessor
may require Lessee to provide Lessor, at Lessee's sole cost and expense, a lien
and completion bond in an amount equal to one and one-half times the estimated
cost of such improvements, to insure Lessor against any liability for mechanic's
and materialmen's liens and to insure completion of the work. Should Lessee make
any alterations, improvements, additions or Utility Installations without the
prior approval of Lessor, or use a contractor not expressly approved by Lessor,
Lessor may, at any time during the term of this Lease, require that Lessee
remove any part of or all of the same.

                                       9
<PAGE>
 
          (b) Any alterations, improvements, additions or Utility Installations
in or about the Premises or the Office Building Project that Lessee shall desire
to make shall be presented to Lessor in written form, with proposed detailed
plans. If Lessor shall give its consent to Lessee's making such alteration,
improvement, addition or Utility Installation, the consent shall be deemed
conditioned upon Lessee acquiring a permit to do so from the applicable
governmental agencies, furnishing a copy thereof to Lessor prior to the
commencement of the work, and compliance by Lessee with all conditions of said
permit in a prompt and expeditious manner.

          (c) Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, the Building or the Office Building
Project, or any interest therein.

          (d) Lessee shall give Lessor not less than ten (10) days' notice prior
to the commencement of any work in the Premises by Lessee, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises or the
Building as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises, the Building or the Office Building
Project, upon the condition that if Lessor shall require, Lessee shall furnish
to Lessor a surety bond satisfactory to Lessor in an amount equal to such
contested lien claim or demand indemnifying Lessor against liability for the
same and holding the Premises, the Building and the Office Building Project free
from the effect of such lien or claim. In addition, Lessor may require Lessee to
pay Lessor's reasonable attorneys' fees and costs in participating in such
action if Lessor shall decide it is to Lessor's best interest to do so.

          (e) All alterations, improvements, additions and Utility
Installations(whether or not such Utility Installations constitute trade
fixtures of Lessee), which may be made to the Premises by Lessee, including but
not limited to, floor coverings, panelings, doors, drapes, built-ins, moldings,
sound attenuation, and lighting and telephone or communication systems,
conduit, wiring, and outlets, shall be made and done in a good and workmanlike
manner and of good and sufficient quality and materials and shall be the
property of Lessor and remain upon and be surrendered with the Premises at the
expiration of the Lease term, unless Lessor requires their removal pursuant to
paragraph 7.3(e). Provided Lessee is not in default, notwithstanding the
provisions of this paragraph 7.3(e). Lessee's personal property and equipment,
other than that which is affixed to the Premises so that it cannot be removed
without material damage to the Premises or the Building, and other than Utility
Installations, shall remain the property of Lessee and may be removed by Lessee
subject to the provisions of paragraph 7.2.

          (f) Lessee shall provide Lessor with as-built plans and specifications
for any alterations, improvements, additions, or Utility Installations.

                                      10
<PAGE>
 
     7.4. UTILITY ADDITIONS. Lessor reserves the right to install new or
additional utility facilities throughout the Office Building Project for the
benefit of Lessor or Lessee, or any other lessee of the Office Building Project,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, communication systems, and fire protection and detection systems, so
long as such installations do not unreasonably interfere with Lessee's use of
the Premises.

8.   INSURANCE; INDEMNITY.

     8.1. LIABILITY INSURANCE-LESSEE. Lessee shall, at Lessee's expense, obtain
and keep in force during the term of this Lease a policy of Comprehensive
General Liability insurance utilizing an Insurance Services Office standard form
with Broad Form General Liability Endorsement (GL0404), or equivalent, in amount
of not less than 3,000,000 per occurrence of bodily injury and property damage
combined or in a greater amount as reasonably determined by Lessor and shall
insure Lessee with Lessor as an additional insured against liability arising out
of use, occupancy or maintenance of the Premises. Compliance with the above
requirement shall not, however, limit the liability of Lessee hereunder.

     8.2. LIABILITY INSURANCE-LESSOR. Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury
and Broad Form Property Damage Insurance, plus coverage against such other risks
Lessor deems advisable from time to time, insuring Lessor, but not Lessee,
against liability arising out of the ownership, use, occupancy or maintenance of
the Office Building Project in an amount not less than $5,000,000.00 per
occurrence.

     8.3. PROPERTY INSURANCE-LESSEE. Lessee shall, at Lessee's expense, obtain
and keep in force during the term of this Lease for the benefit of Lessee,
replacement cost fire and extended coverage insurance, with vandalism and
malicious mischief, sprinkler leakage and earthquake sprinkler leakage
endorsements, in an amount sufficient to cover not less than 100% of the full
replacement cost, as the same may exist from time to time, of all of Lessee's
personal property, fixtures, equipment and tenant improvements.

     8.4. PROPERTY INSURANCE-LESSOR. Lessor shall obtain and keep in force
during the term of this Lease a policy or policies of insurance covering loss or
damage to the Office Building Project improvements, but not Lessee's personal
property, fixtures, equipment or tenant improvements, in the amount of the full
replacement cost thereof, as the same may exist from time to time, utilizing
Insurance Services Office standard form, or equivalent, providing protection
against all perils included within the classification of fire, extended
coverage, vandalism, malicious mischief, plate glass, and such other perils as
Lessor deems advisable or may be required by a lender having a lien on the
Office Building Project. In addition, Lessor shall obtain and keep in force,
during the term of this Lease, a policy of rental value insurance covering a
period of one year, with loss payable to Lessor, which insurance shall also
cover all Operating Expenses for said period. Lessee will not be named in any
such policies carried by Lessor and shall have no right to any proceeds
therefrom. The policies required by these paragraphs 8.2 and 8.4 shall contain
such deductibles as Lessor or the aforesaid lender may determine. In the event
that the Premises shall suffer an insured loss as defined in paragraph

                                      11
<PAGE>
 
9.1(f) hereof, the deductible amounts under the applicable insurance policies
shall be deemed an Operating Expense. Lessee shall not do or permit to be done
anything which shall invalidate the policies carried by Lessor. Lessee shall pay
the entirety of any increase in the property insurance premium for the Office
Building Project over what it was immediately prior to the commencement of the
term of this Lease if the increase is specified by Lessor's insurance carrier as
being caused by the nature of Lessee's occupancy or any act or omission of
Lessee.

     8.5. INSURANCE POLICIES. Lessee shall deliver to Lessor copies of liability
insurance policies required under paragraph 8.1 or certificates evidencing the
existence and amounts of such insurance within seven (7) days after the
Commencement Date of this Lease. No such policy shall be cancellable or subject
to reduction of coverage or other modification except after thirty (30) days
prior written notice to Lessor. Lessee shall, at least thirty (30) days prior to
the expiration of such policies, furnish Lessor with renewals thereof.

     8.6. WAIVER OF SUBROGATION. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other,
for direct or consequential loss or damage arising out of or incident to the
perils covered by property insurance carried by such party, whether due to the
negligence of Lessor or Lessee or their agents, employees, contractors and/or
invitees. If necessary all property insurance policies required under this Lease
shall be endorsed to so provide.

     8.7. INDEMNITY. Lessee shall indemnify and hold harmless Lessor and its
agents, Lessor's master or ground lessor, partners and lenders, from and against
any and all claims for damage to the person or property of anyone or any entity
arising from Lessee's use of the Office Building Project, or from the conduct of
Lessee's business or from any activity, work or things done, permitted or
suffered by Lessee in or about the Premises or elsewhere and shall further
indemnify and hold harmless Lessor from and against any and all claims, costs
and expenses arising from any breach or default in the performance of any
obligation on Lessee's part to be performed under the terms of this Lease, or
arising from any act or omission of Lessee, or any of Lessee's agents,
contractors, employees, or invitees, and from and against all costs, attorney's
fees, expenses and liabilities incurred by the Lessor as the result of any such
use, conduct, activity, work, things done, permitted or suffered, breach,
default or negligence, and in dealing reasonably therewith, including but not
limited to the defense or pursuit of any claim or any action proceeding involved
therein; and in case any action or proceeding be brought against Lessor by
reason of any such matter, Lessee upon notice from Lessor shall defend the same
at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be so indemnified. Lessee, as a material part of the
consideration to Lessor, hereby assumes all risk of damage to property of Lessee
or injury to persons, in, upon or about the Office Building Project arising from
any cause and Lessee hereby waives all claims in respect thereof against Lessor.

     8.8. EXEMPTION OF LESSOR FROM LIABILITY. Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for loss of or damage to the goods, wares, merchandise or other
property of Lessee, Lessee's employees, invitees, customers, or any other person
in or about the Premises or the Office Building Project, nor shall

                                      12
<PAGE>
 
Lessor be liable for injury to the person of Lessee, Lessee's employees, agents
or contractors, whether such damage or injury is caused by or results from
theft, fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, sprinklers, wires, appliances,
plumbing, air conditioning or lighting fixtures, or from any other cause,
whether said damage or injury results from conditions arising upon the Premises
or upon other portions of the Office Building Project, or from other sources or
places, or from new construction or the repair, alteration or improvement of any
part of the Office Building Project, or of the equipment, fixtures or
appurtenances applicable thereto, and regardless of whether the cause of such
damage or injury or the means of repairing the same is inaccessible. Lessor
shall not be liable for any damages arising from any act or neglect of any other
lessee, occupant or user of the Office Building Project, nor from the failure of
Lessor to enforce the provisions of any other lease of any other lessee of the
Office Building Project.

     8.9. NO REPRESENTATION OF ADEQUATE COVERAGE. Lessor makes no representation
that the limits or forms of coverage of insurance specified in this paragraph 8
are adequate to cover Lessee's property or obligations under this Lease.

destroyed to any extent.

          (b) "Premises Building Partial Damage" shall mean if the Building of

          (f) "Insured Loss" shall mean damage or destruction which was caused
by an event required to be covered by the insurance described in paragraph 8.

spent in order to repair or rebuild the damaged area to the condition that
existed immediately

                                      13

     9.2. PREMISES DAMAGE; PREMISES BUILDING PARTIAL DAMAGE.

          (a) Insured Loss: Subject to the provisions of paragraphs 9.4 and 9.5,
if at any time during the term of this Lease there is damage which is an Insured
Loss and which falls into the classification of either Premises Damage or
Premises Building Partial Damage, then Lessor shall, as soon as reasonably
possible and to the extent the required materials and labor are readily
available through usual commercial channels, at Lessor's expense, repair such
damage (but not Lessee's fixtures, equipment or tenant improvements originally
paid for by Lessee) to its condition existing at the time of the damage, and
this Lease shall continue in full force and effect.

          (b) Uninsured Loss: Subject to the provisions of paragraphs 9.4 and
9.5, if at any time during the term of this Lease there is damage which is not
an Insured Loss and which falls within the classification of Premises Damage or
Premises Building Partial Damage, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense), which
damage prevents Lessee from making any substantial use of the Premises, Lessor
may at Lessor's option either (i) repair such damage as soon as reasonably
possible at Lessor's expense, in which event this Lease shall continue in full
force and effect, or (ii) give written notice to Lessee within thirty (30) days
after the date of the occurrence of such damage of Lessor's intention to cancel
and terminate this Lease as of the date of the occurrence of such damage, in
which event this Lease shall terminate as of the date of the occurrence of such
damage.

     9.3. PREMISES BUILDING TOTAL DESTRUCTION; OFFICE BUILDING PROJECT TOTAL

condition existing at the time of the damage, but not Lessee's fixtures,
equipment or tenant improvements, and this Lease shall continue in full force
and effect, or (iii) give written notice to Lessee within thirty (30) days after
the date of occurrence of such damage of Lessor's intention to cancel and
terminate this Lease, in which case this Lease shall terminate as of the date of
the occurrence of such damage.

     9.4. DAMAGE NEAR END OF TERM.

          (a) Subject to paragraph 9.4(b), if at any time during the last twelve
(12) months of the term of this Lease there is substantial damage to the
Premises, Lessor may at Lessor's option cancel and terminate this Lease as of
the date of occurrence of such damage by giving written notice to Lessee of
Lessor's election to do so within 30 days after the date of occurrence of such
damage.

                                      14
<PAGE>
 
          (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has an
option to extend or renew this Lease, and the time within which said option may
be exercised has not yet expired, Lessee shall exercise such option, if it is to
be exercised at all, no later than twenty (20) days after an occurrence of an
Insured Loss falling within the classification of Premises Damage during the
last twelve (12) months of the term of this Lease. If Lessee duly exercises such
option during said twenty (20) day period, Lessor shall, at Lessor's expense,
repair such damage, but not Lessee's fixtures, equipment or tenant improvements,
as soon as reasonably possible and this Lease shall continue in full force and
effect. If Lessee fails to exercise such option during said twenty (20) day
period, then Lessor may at Lessor's option terminate and cancel this Lease as of
the expiration of said twenty (20) day period, notwithstanding any term or
provision in the grant of option to the contrary.

     9.5. ABATEMENT OF RENT; LESSEE'S REMEDIES.

          (a) In the event Lessor repairs or restores the Building or Premises
pursuant to the provisions of this paragraph 9, and any part of the Premises are
not usable (including loss of use due to loss of access or essential services),
the rent payable hereunder (including Lessee's Share of Operating Expense
Increase) for the period during which such damage, repair or restoration
continues shall be abated, provided (1) the damage was not the result of the
negligence of Lessee, and (2) such abatement shall only be to the extent the
operation and profitability of Lessee's business as operated from the Premises
is adversely affected. Except for said abatement of rent, if any, Lessee shall
have no claim against Lessor for any damage suffered by reason of any such
damage, destruction, repair or restoration.

          (b) If Lessor shall be obligated to repair or restore the Premises or
the Building under the provisions of this Paragraph 9 and shall not commence
such repair or restoration within ninety (90) days after such occurrence, or if
Lessor shall not complete the restoration and repair within six (6) months after
such occurrence, Lessee may at Lessee's option cancel and terminate this Lease
by giving Lessor written notice of Lessee's election to do so at any time prior
to the commencement or completion, respectively, of such repair or restoration.
In such event this Lease shall terminate as of the date of such notice.

          (c) Lessee agrees to cooperate with Lessor in connection with any such
restoration and repair, including but not limited to the approval and/or
execution of plans and specifications required.

     9.6. TERMINATION-ADVANCE PAYMENTS. Upon termination of this Lease pursuant
to this paragraph 9, an equitable adjustment shall be made concerning advance
rent and any advance payments made by Lessee to Lessor. Lessor shall, in
addition, return to Lessee so much of Lessee's security deposit as has not
theretofore been applied by Lessor.

     9.7. WAIVER. Lessor and Lessee waive the provisions of any statute which
relate to termination of leases when leased property is destroyed and agree that
such event shall be governed by the terms of this Lease.

10.  REAL PROPERTY TAXES.

                                      15
<PAGE>
 
     10.1. PAYMENT OF TAXES. Lessor shall pay the real property tax, as defined
in paragraph 10.3, applicable to the Office Building Project subject to
reimbursement by Lessee of Lessee's Share of such taxes in accordance with the
provisions of paragraph 4.2, except as otherwise provided in paragraph 10.2

     10.2. ADDITIONAL IMPROVEMENTS. Lessee shall not be responsible for paying
any increase in real property tax specified in the tax assessor's records and
work sheets as being caused by additional improvements placed upon the Office
Building Project by other lessees or by Lessor for the exclusive enjoyment of
any other lessee. Lessee shall, however, pay to Lessor at the time that
Operating Expenses are payable under paragraph 4.2(c) the entirety of any
increase in real property tax if assessed solely by reason of additional
improvements placed upon the Premises by Lessee or at Lessee's request.

     10.3. DEFINITION OF "REAL PROPERTY TAX." As used herein, the term "real
property tax" shall include any form of real estate tax or assessment, general,
special, ordinary or extraordinary, any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Office Building Project or any portion thereof
by any authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary,
fire, street, drainage or other improvement district thereof, as against any
legal or equitable interest of Lessor in the Office Building Project or in any
portion thereof, as against Lessor's right to rent or other income therefrom,
and as against Lessor's business of leasing the Office Building Project. The
term "real property tax" shall also include any tax, fee, levy, assessment or
charge (i) in substitution of, partially or totally, any tax, fee, levy,
assessment or charge hereinabove included within the definition of "real
property tax," or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a service or
right not charged prior to June 1, 1978, or, if previously charged, has been
increased since June 1, 1978, or (iv) which is imposed as a result of a change
in ownership, as defined by applicable local statutes for property tax purposes,
of the Office Building Project or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such change of
ownership, or (v) which is imposed by reason of this transaction, any
modification or changes hereto, or any transfers hereof.

     10.4. JOINT ASSESSMENT. If the improvements or property, the taxes for
which are to be paid separately by Lessee under paragraph 10.2 or 10.5 are not
separately assessed, Lessee's portion of that tax shall be equitably determined
by Lessor from the respective valuations assigned in the assessor's work sheets
or such other information (which may include the cost of construction) as may be
reasonable available. Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

     10.5. PERSONAL PROPERTY TAXES.

           (a) Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere.

                                      16
<PAGE>
 
           (b) If any of Lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay to Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property.

11.  UTILITIES.

     11.1. SERVICES PROVIDED BY LESSOR. Lessor shall provide heating,
ventilation, air conditioning, and janitorial service as reasonably required,
reasonable amounts of electricity for normal lighting and office machines, water
for reasonable and normal drinking and lavatory use, and replacement light bulbs
and/or fluorescent tubes and ballasts for standard overhead fixtures.

     11.2. SERVICES EXCLUSIVE TO LESSEE. Lessee shall pay for all water, gas,
heat, light, power, telephone and other utilities and services specially or
exclusively supplied and/or metered exclusively to the Premises or to Lessee,
together with any taxes thereon. If any such services are not separately metered
to the Premises, Lessee shall pay at Lessor's option, either Lessee's Share or a
reasonable proportion to be determined by Lessor of all charges jointly metered
with other premises in the Building.

     11.3. HOURS OF SERVICES. Said services and utilities shall be provided
during generally accepted business days and hours of such other days or hours as
may hereafter be set forth. Utilities and services required at other times shall
be subject to advance request and reimbursement by Lessee to Lessor of the cost
thereof. See Paragraph 11.3 of the attached Addendum.

     11.4. EXCESS USAGE BY LESSEE. Lessee shall not make connection to the
utilities except by or through existing outlets and shall not install or use
machinery or equipment in or about the Premises that uses excess water, lighting
or power, or suffer or permit any act that causes extra burden upon the
utilities or services, including but not limited to security services, over
standard office usage for the Office Building Project. Lessor shall require
Lessee to reimburse Lessor for any excess expenses or costs that may arise out
of a breach of this subparagraph by Lessee. Lessor may, in its sole discretion,
install at Lessee's expense supplemental equipment and/or separate metering
applicable to Lessee's excess usage or loading.

     11.5. INTERRUPTIONS. There shall be no abatement of rent and Lessor shall
not be liable in any respect whatsoever for the inadequacy, stoppage,
interruption or discontinuance of any utility or service due to riot, strike,
labor dispute, breakdown, accident, repair or other cause beyond Lessor's
reasonable control or in cooperation with governmental request or directions.

12.  ASSIGNMENT AND SUBLETTING. See paragraph 12.1 of the attached Addendum.

     12.1. LESSOR'S CONSENT REQUIRES. Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting

                                      17
<PAGE>
 
without such consent shall be void, and shall constitute a material default and
breach of this Lease without the need for notice to Lessee under paragraph 13.1.
"Transfer" within the meaning of this paragraph 12 shall include the transfer or
transfers aggregating: (a) if Lessee is a corporation, more than twenty-five
percent (25%) of the voting stock of such corporation, or (b) if Lessee is a
partnership, more than twenty-five percent (25%) of the profit and loss
participation in such partnership.

     12.2. LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate";
provided that before such assignment shall be effective, (a) said assignee shall
assume, in full, the obligations of Lessee under this Lease and (b) Lessor shall
be given written notice of such assignment and assumption. Any such assignment
shall not, in any way, affect or limit the liability of Lessee under the terms
of this Lease even if after such assignment or subletting the terms of this
Lease are materially changed or altered without the consent of Lessee, the
consent of whom shall not be necessary.

     12.3. TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

           (a) Regardless of Lessor's consent, no assignment or subletting shall
release Lessee of Lessee's obligations hereunder or after the primary liability
of Lessee to pay the rent and other sums due Lessor hereunder including Lessee's
Share of Operating Expense Increase, and to perform all other obligations to be
performed by Lessee hereunder.

           (b) Lessor may accept rent from any person other than Lessee pending
approval or disapproval of such assignment.

           (c) Neither a delay in the approval or disapproval of such assignment
or subletting, nor the acceptance or rent, shall constitute a waiver or estoppel
of Lessor's right to exercise its remedies for the breach of any of the terms or
conditions of this paragraph 12 or this Lease.

           (d) If Lessee's obligations under this Lease have been guaranteed by
third parties, then an assignment or sublease, and Lessor's consent thereto
shall not be effective unless said guarantors give their written consent to such
sublease and the terms thereof.

           (e) The consent by Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent subletting and assignments of the sublease or
any amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent and such
action shall not relieve such persons from liability under this Lease or said
sublease; however, such persons shall not be responsible to the extent any such

                                      18
<PAGE>
 
amendment or modification enlarges or increases the obligations of the Lessee or
sublessee under this Lease or such sublease.

           (f) In the event of any default under this Lease, Lessor may proceed
directly against Lessee, any guarantors or any one else responsible for the
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor or Lessee.

           (g) Lessor's written consent to any assignment or subletting of the
Premises by Lessee shall not constitute an acknowledgment that no default then
exists under this Lease of the obligations to be performed by Lessee nor shall
such consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

           (h) The discovery of the fact that any financial statement relied
upon by Lessor in giving its consent to an assignment or subletting was
materially false shall, at Lessor's election, render Lessor's said consent null
and void.

     12.4. ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. Regardless
of Lessor's consent, the following terms and conditions shall apply to any
subletting by Lessee of all or any part of the Premises and shall be deemed
included in all subleases under this Lease whether or not expressly incorporated
therein:

           (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease, Lessee may receive, collect and enjoy the rents accruing under such
sublease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor nor by reason of the collection of the rents from a
sublessee, be deemed liable to the subleasee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a default exists in
the performance of Lessee's obligations under this Lease, to pay to Lessor the
rents due and to become due under the sublease. Lessee agrees that such
sublessee shall have the right to rely upon any such statement and request from
Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against said sublessee or Lessor for any such rents
so paid by said sublessee to Lessor.

           (b) No sublease entered into by Lessee shall be effective unless and
until it has been approved in writing by Lessor. In entering into any sublease,
Lessee shall use only such form of sublessee as is satisfactory to Lessor, and
once approved by Lessor, such sublease shall not be changed or modified without
Lessor's prior written consent. Any sublease shall, by reason of entering into a
sublease under this Lease, be deemed, for the benefit of Lessor, to have assumed
and agreed to conform and comply with each and every obligation herein to be

                                      19
<PAGE>
 
performed by Lessee other than such obligations as are contrary to or
inconsistent with provisions contained in a sublease to which Lessor has
expressly consented in writing.

           (c) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor at its option and without any obligation to
do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Lessee or for any other prior defaults of Lessee under
such sublease.

           (d) No sublessee shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

           (e) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within three (3) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee.

     12.5. LESSOR'S EXPENSES. In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable costs and expenses incurred in
connection therewith, including the attorneys', architects', engineers' or other
consultants' fees.

     12.6. CONDITIONS TO CONSENT. Lessor reserves the right to condition any
approval to assign or sublet upon Lessor's determination that (a) the proposed
assignee or sublessee shall conduct a business on the Premises of a quality
substantially equal to that of Lessee and consistent with the general character
of the other occupants of the Office Building Project and not in violation of
any exclusives or rights then held by other tenants, and (b) the proposed
assignee or sublessee be at least as financially responsible as Lessee was
expected to be at the time of the execution of this Lease or of such assignment
or subletting, whichever is greater.

13.  DEFAULT; REMEDIES.

     13.1. DEFAULT. The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

           (a) The vacation or abandonment of the Premises by Lessee. Vacation
of the Premises shall include the failure to occupy the Premises for a
continuous period of sixty (60) days or more, whether or not the rent is paid.

           (b) The breach by Lessee of any of the covenants, conditions or
provisions of paragraphs 7.3(a), (b) or (d) (alterations), 12.1 (assignment or
subletting), 13.1(a) (vacation or abandonment), 13.1(e) (insolvency), 13.1(f)
(false statement), 16(a) (estoppel certificate), 30(b)

                                      20
<PAGE>
 
(subordination), 33 (auctions), or 41.1 (easements), all of which are hereby
deemed to be material, non-curable defaults without the necessity of any notice
by Lessor to Lessee thereof.

           (c) The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, where such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph.

           (d) The failure by Lessee to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Lessee
other than those referenced in subparagraphs (b) and (c) above, where such
failure shall continue for a period of thirty (30) days after written notice
thereof from Lessor to Lessee; provided, however, that if the nature of Lessee's
noncompliance is such that more than thirty (30) days are reasonably required
for its cure, then Lessee shall not be deemed to be in default if Lessee
commenced such cure within said thirty (30) day period and thereafter diligently
pursues such cure to completion. To the extent permitted by law, such thirty
(30) day notice shall constitute the sole and exclusive notice required to be
given to Lessee under applicable Unlawful Detainer statutes.

           (e)(i) The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becoming a "debtor" as
defined in 11 U.S.C. ss.101 for any successor statute thereto (unless, in the
case of a petition filed against Lessee, the same is dismissed within sixty (60)
days; (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days. In the event that any provision of this paragraph 13.1(e) is contrary to
any applicable law, such provision shall be of no force or effect.

           (f) The discovery by Lessor that any financial statement given to
Lessor by Lessee, or its successor in interest or by any guarantor of Lessee's
obligation hereunder, was materially false.

     13.2. REMEDIES. In the event of any material default or breach of this
Lease by Lessee, Lessor may at any time thereafter, with or without notice or
demand and without limiting Lessor in the exercise of any right or remedy which
Lessor may have by reason of such default:

           (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee all damages incurred by
Lessor by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorneys' fees,
and any real estate commission actually paid; the worth at the time of award by
the court

                                      21
<PAGE>
 
having jurisdiction thereof of the amount by which the unpaid rent for the
balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

           (b)  Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

           (c)  Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

     13.3. DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor fails
to perform obligations required of Lessor within a reasonable time, but in no
event later than thirty (3) days after written notice by Lessee to Lessor and to
the holder of any first mortgage or deed of trust covering the Premises whose
name and address shall have theretofore been furnished to Lessee in writing,
specifying wherein Lessor has failed to perform such obligation; provided,
however, that if the nature of Lessor's obligation is such that more than thirty
(30) days are required for performance then Lessor shall not be in default if
Lessor commences performance within such 30-day period and thereafter diligently
pursues the same to completion.

     13.4. LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
to Lessor of Base Rent, Lessee's Share of Operating Expense increase or other
sums due hereunder will cause Lessor to incur costs not contemplated by this
Lease, the exact amount of which will be extremely difficult to ascertain. Such
costs include, but are not limited to, processing and accounting charges, and
late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Office Building Project. Accordingly, if any installment
of Base Rent, Operating Expense Increase, or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within ten (10) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to 6% of such overdue amount. The
parties hereby agree that such late charge represents a fair and reasonable
estimate of the costs Lessor will incur by reason of late payment by Lessee.
Acceptance of such late charge by Lessor shall in no event constitute a waiver
of Lessee's default with respect to such overdue amount, nor prevent Lessor from
exercising any of the other rights and remedies granted hereunder.

14.  CONDEMNATION. If the Premises or any portion thereof or the Office Building
Project are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs; provided that if so
much of the Premises or the Office Building Project are taken by such
condemnation as would substantially and adversely affect the operation and
profitability of 

                                       22
<PAGE>
 
Lessee's business conducted from the Premises, Lessee shall have the option, to
be exercised only in writing within thirty (30) days after Lessor shall have
given Lessee written notice of such taking (or in the absence of such notice,
within thirty (30) days after the condemning authority shall have taken
possession), to terminate this Lease as of the date the condemning authority
takes such possession. If Lessee does not terminate this Lease in accordance
with the foregoing, this Lease shall remain in full force and effect as to the
portion of the Premises remaining, except that the rent and Lessee's Share of
Operating Expense Increase shall be reduced in the proportion that the floor
area of the Premises taken bears to the total floor area of the Premises. Common
Areas taken shall be excluded from the Common Areas usable by Lessee and no
reduction or rent shall occur with respect thereto or by reason thereof. Lessor
shall have the option in its sole discretion to terminate this Lease as of the
taking of possession by the condemning authority, by giving written notice to
Lessee of such election within thirty (30) days after receipt of notice of a
taking by condemnation of any part of the Premises or the Office Building
Project. Any award for the taking of al or any part of the Premises or the
Office Building Project under the power of eminent domain or any payment made
under threat of the exercise of such power shall be the property of Lessor,
whether such award shall be made as compensation for diminution in value of the
leasehold or for the taking of the fee, or as severance damages: provided,
however, that Lessee shall be entitled to any separate award for loss of or
damage to Lessee's trade fixtures, removable personal property and unamortized
tenant improvements that have been paid for by Lessee. For that purpose the cost
of such improvements shall be amortized over the original term of this Lease
excluding any options. In the event that this Lease is not terminated by reason
of such condemnation, Lessor shall to the extent of severance damages received
by Lessor in connection with such condemnation, repair any damage to the
Premises caused by such condemnation except to the extent that Lessee has been
reimbursed therefor by the condemning authority. Lessee shall pay any amount in
excess of such severance damages required to complete such repair.

15.  BROKER'S FEE.

          (a)  The broker's involved in this transaction are 
The Seeley Company as "listing broker" and None as "cooperating broker,"
licensed real estate broker(s). A "cooperating broker" is defined as any broker
other than the listing broker entitled to a share of any commission arising
under this Lease. Upon execution of this Lease by both parties, Lessor shall pay
to said brokers jointly, or in such separate shares as they may mutually
designate in writing, a fee as set forth in a separate agreement between Lessor
and said broker(s).

          (d)  Lessee and Lessor each represent and warrant to the other that
neither has had any dealings with any person, firm, broker, or finder (other
than the person(s), if any, whose names are set forth in paragraph 15(a), above)
in connection with the negotiation of this Lease and/or the consummation of the
transaction contemplated hereby, and no other broker or other person, firm or
entity is entitled to any commission or finder's fee in connection with said
transaction and Lessee and Lessor do each hereby indemnify and hold the other
harmless from

                                       23
<PAGE>
 
and against any costs, expenses, attorneys' fees or liability for compensation
or charges which may be claimed by any such unnamed broker, finder or other
similar party by reason of any dealings or actions of the indemnifying party.

16.  ESTOPPEL CERTIFICATE.

          (a)  Each party (as "responding party") shall at any time upon not
less than ten (10) days' prior written notice from the other party ("requesting
party") execute, acknowledge and deliver to the requesting party a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults on the part of the requesting party, or specifying such
defaults if any are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbracer of the Office Building Project or of
the business of Lessee.

          (b)  At the requesting party's option, the failure to deliver such
statement within such time shall be a material default of this Lease by the
party who is to respond, without any further notice to such party, or it shall
be conclusive upon such party that (i) this Lease is in full force and effect
without modification except as may be represented by the requesting party, (ii)
there are no uncured defaults in the requesting party's performance, and (iii)
if Lessor is the requesting party, not more than one month's rent has been paid
in advance.

          (c)  If Lessor desires to finance, refinance, or sell the Office
Building Project, or any part thereof, Lessee hereby agrees to deliver to any
lender or purchaser designated by Lessor such financial statements of Lessee as
may be reasonably required by such lender or purchaser. Such statements shall
include the past three (3) years' financial statements of Lessee. All such
financial statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17.  LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Office Building Project, and except as
expressly provided in paragraph 15, in the event of any transfer of such title
or interest, Lessor herein named (and in case of any subsequent transfers then
the grantor) shall be relieved from and after the date of such transfer of all
liability as respects Lessor's obligations thereafter to be performed, provided
that any funds in the hands of Lessor or the then grantor at the time of such
transfer, in which Lessee has an interest, shall be delivered to the grantee.
The obligations contained in this Lease to be performed by Lessor shall, subject
as aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

18.  SEVERABILITY. The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction shall in no way affect the validity of any
other provision hereof.

                                       24
<PAGE>
 
19.  INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law or judgments from the date due. Payment of such interest
shall not excuse or cure any default by Lessee under this Lease; provided,
however, that interest shall not be payable on late charges incurred by Lessee
nor on any amounts upon which late charges are paid by Lessee.

20.  TIME OF ESSENCE. Time is of the essence with respect to the obligations to
be performed under this Lease.

21.  ADDITIONAL RENT. All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expense Increase and any other expenses payable by Lessee hereunder shall be
deemed to be rent.

22.  INCORPORATION OF PRIOR AGREEMENTS. This Lease contains all agreements of
the parties with respect to any matter mentioned herein. No prior or
contemporaneous agreements of understanding pertaining to any such matter shall
be effective. This Lease may be modified in writing only, signed by the parties
in interest at the time of the modification. Except as otherwise stated in this
Lease, Lessee hereby acknowledges that neither the real estate broker listed in
paragraph 15 hereof nor any cooperating broker on this transaction nor the
Lessor or any employee or agents of any of said persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or the Office Building Project and Lessee acknowledges
that Lessee assumes all responsibility regarding the Occupational Safety Health
Act, the legal use and adaptability of the Premises and the compliance thereof
with all applicable laws and regulations in effect during the term of this
Lease.

23.  NOTICES. Any notice required or permitted to be given hereunder shall
be in writing and may be given by personal delivery or by certified or
registered mail, and shall be deemed sufficiently given if delivered or
addressed to Lessee or to Lessor at the address noted below or adjacent to the
signature of the respective parties, as the case may be. Mailed notices shall be
deemed given upon actual receipt at the address required, or forty-eight hours
following deposit in the mail, postage prepaid, whichever first occurs. Either
party may by notice to the other specify a different address for notice purposes
except that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for notice purposes. A copy of all notices required
or permitted to be given to Lessor hereunder shall be concurrently transmitted
to such party or parties at such addresses as Lessor may from time to time
hereafter designate by notice to Lessee.

24.  WAIVERS. No waiver by Lessor of any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision. Lessor's consent to, or approval of, any act
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee. The acceptance of rent hereunder by
Lessor shall not be a waiver of any preceding breach by Lessee of any provision
hereof, other than the failure of Lessee to pay the particular rent so accepted,

                                       25
<PAGE>
 
regardless of Lessor's knowledge of such preceding breach at the time of
acceptance of such rent.

25.  RECORDING. Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26.  HOLDING OVER. If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions in this
Lease pertaining to the obligations of Lessee, except that the rent payable
shall be two hundred percent (200%) of the rent payable immediately preceding
the termination date of this Lease, and all Options, if any, granted under the
terms of this Lease shall be deemed terminated and be of no further effect
during said month to month tenancy.

27.  CUMULATIVE REMEDIES. No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.  COVENANTS AND CONDITIONS. Each provision of this Lease performed by Lessee
shall be deemed both a covenant and a condition.

29.  BINDING EFFECT; CHOICE OF LAW. Subject to any provisions hereof restricting
assignment or subletting by Lessee and subject o the provisions of paragraph 17,
this Lease shall bind the parties, their personal representatives, successors
and assigns. This Lease shall be governed by the laws of the Sate where the
Office Building Project is located and any litigation concerning this Lease
between the parties hereto shall be initiated in the county in which the Office
Building Project is located.

30.  SUBORDINATION.

          (a)  This Lease, and any Option or right of first refusal granted
hereby, at Lessor's option, shall be subordinate to any ground lease, mortgage,
deed of trust, or any other hypothecation or security now or hereafter placed
upon the Office Building Project and to any and all advances made on the
security thereof and to all renewals, modifications, consolidations,
replacements and extensions thereof. Notwithstanding such subordination,
Lessee's right to quiet possession of the Premises shall not be disturbed if
Lessee is not in default and so long as Lessee shall pay the rent and observe
and perform all of the provisions of this Lease, unless this Lease is otherwise
terminated pursuant to its terms. If any mortgagee, trustee or ground lessor
shall elect to have this Lease and any Options granted hereby prior to the lien
of its mortgage, deed of trust or ground lease, and shall give written notice
thereof to Lessee, this Lease and such Options shall be deemed prior to such
mortgage, deed of trust or ground lease, whether this Lease or such Options are
dated prior to subsequent to the date of said mortgage, deed of trust or ground
lease or the date of recording thereof.

          (b)  Lessee agrees to execute any documents required to effectuate an
attornment, a subordination, or to make this Lease or any Option granted herein
prior to the lien

                                       26
<PAGE>
 
of any mortgage, deed of trust or ground lease, as the case may be. Lessee's
failure to execute such documents within ten (10) days after written demand
shall constitute a material default by Lessee hereunder without further notice
to Lessee or, at Lessor's option, Lessor shall execute such documents on behalf
of Lessee as Lessee's attorney-in-fact. Lessee does hereby make, constitute and
irrevocably appoint Lessor as Lessee's attorney-in-fact and in Lessee's name,
place and stead, to execute such documents in accordance with this paragraph
30(b).

31.  ATTORNEYS' FEES.

     31.1. If either party or the broker(s) named herein bring an action to
enforce the terms hereof or declare rights hereunder, the prevailing party in
any such action, trial or appeal thereon, shall be entitled to his reasonable
attorneys' fees to be paid by the losing party as fixed by the court in the same
or a separate suit, and whether or not such action is pursued to decision or
judgment. The provisions of this paragraph shall insure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

     31.2. The attorneys' fees award shall not be computed in accordance with
any court fee schedule, but shall be such as to fully reimburse all attorneys'
fees reasonably incurred in good faith.

     31.3. Lessor shall be entitled to reasonable attorneys' fees and all other
costs and expenses incurred in the preparation and service of notice of default
and consultation in connection therewith, whether or not a legal transaction is
subsequently commenced in connection with such default.

32.  LESSOR'S ACCESS.

     32.1. Lessor and Lessor's agents shall have the right to enter the Premises
at reasonable times for the purpose of inspecting the same, performing any
services required of Lessor, showing the same to prospective purchasers,
lenders, or lessees, taking such safety measures, erecting such scaffolding or
other necessary structures, making such alterations, repairs, improvements or
additions to the Premises or to the Office Building Project as Lessor may
reasonably deem necessary or desirable and the erecting, using and maintaining
of utilities, services, pipes and conduits through the Premises and/or other
premises as long as there is no material adverse effect to Lessee's use of the
Premises. Lessor may at any time place on or about the Premises or the Building
any ordinary "For Sale" signs and Lessor may at any time during the last 120
days of the term hereof place on or about the Premises any ordinary "For Lease"
signs.

     32.2. All activities of Lessor pursuant to this paragraph shall be without
abatement of rent, nor shall Lessor have any liability to Lessee for the same.

     32.3. Lessor shall have the right to retain keys to the Premises and to
unlock doors in or upon the Premises other than to files, vaults and safes, and
in the case of emergency to enter the Premises by any reasonably appropriate
means, and any such entry shall not be deemed a forceable or unlawful entry or
detainer of the Premises or an eviction. Lessee waives any

                                       27
<PAGE>
 
charges for damages or injuries or interference with Lessee's property or
business in connection therewith.

33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent. Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such
consent. The holding of any auction on the Premises or Common Areas in violation
of this paragraph shall constitute a material default of this Lease.

34.  SIGNS. Lessee shall not place any sign upon the Premises or the Office
Building Project without Lessor's prior written consent. Under no circumstances
shall Lessee place a sign on any roof of the Office Building Project.

35.  MERGER. The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to Lessor
of any or all of such subtenancies.

36.  CONSENTS. Except for paragraph 33 (auctions) and 34 (signs) hereof,
wherever in this Lease the consent of one party is required to an act of the
other party such consent shall not be reasonably withheld or delayed.

37.  GUARANTOR. In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

38.  QUIET POSSESSION. Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease. The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Office Building Project.

39.  OPTIONS.

     39.1. DEFINITION. As used in this paragraph the word "Option" has the
following meaning: (1) the right or option to extend the term of this Lease or
to renew this Lease or to extend or renew any lease that Lessee has on other
property of Lessor; (2) the option of right of first refusal to lease the
Premises or the right of first offer to lease the Premises or the right of first
refusal to lease other space within the Office Building Project or other
property of Lessor or the right of first offer to lease other space within the
Office Building Project or other property of Lessor; (3) the right or option to
purchase the Premises or the Office Building Project, or the right of first
refusal to purchase the Premises or the Office Building Project or the right of
first offer to purchase the Premises or the Office Building Project, or the
right or option to purchase 

                                       28
<PAGE>
 
other property of Lessor, or the right of first refusal to purchase other
property of Lessor or the right of first offer to purchase other property of
Lessor.

     39.2. OPTIONS PERSONAL. Each Option granted to Lessee in this Lease is
personal to the original Lessee and may be exercised only by the original Lessee
while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or any portion thereof, and may
not be exercised or be assigned, voluntarily or involuntarily, by or to any
person or entity other than Lessee; provided, however, that an Option may be
exercised by or assigned to any Lessee Affiliate as defined in paragraph 12.2 of
this Lease. The Options, if any, herein granted to Lessee are not assignable
separate and apart from this Lease, nor may any Option be separated from this
Lease in any manner, either by reservation or otherwise.

     39.3. MULTIPLE OPTIONS. In the event that Lessee has any multiple options
to extend or renew this Lease a later option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised.

     39.4. EFFECT OF DEFAULT ON OPTIONS.

           (a) Lessee shall have no right to exercise an Option, notwithstanding
any provision in the grant of Option to the contrary, (i) during the time
commencing from the date Lessor gives to Lessee a notice of default pursuant to
paragraph 13.1(c) or 13.1(d) and continuing until the noncompliance alleged in
said notice of default is cured, or (ii) during the period of time commencing on
the day after a monetary obligation to Lessor is due from Lessee and unpaid
(without any necessity for notice thereof to Lessee) and continuing until the
obligation is paid, or (iii) in the event that Lessor has given to Lessee three
or more notices of default under paragraph 13.1(c), or paragraph 13.1(d),
whether or not the defaults are cured, during the 12 month period of time
immediately prior to the time that Lessee attempts to exercise the subject
Option, (iv) if Lessee has committed any non-curable breach, including without
limitation those described in paragraph 13.1(b), or is otherwise in default of
any of the terms, covenants or conditions of this Lease.

           (b) The period of time within which an Option may be exercised shall
not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of paragraph 39.4(a).

           (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessee fails to
commence to cure a default specified in paragraph 13.1(d) within thirty (30)
days after the date that Lessor gives notice to Lessee of such default and/or
Lessee fails thereafter to diligently prosecute said cure to completion, or
(iii) Lessor gives to Lessee three or more notices of default under paragraph
13.1(c), or paragraph 13.1(d), whether or not the defaults are cured, or (iv) if
Lessee has committed any non-curable breach, including without limitation those
described in

conditions or any clean up, remedial, removal or restoration work necessary, in
the reasonable judgment of Lessor, or required by any federal, state or local
governmental agency or political subdivision because of the presence of such
Hazardous Material in, on, under or about the Project or any part thereof
arising out of or relating to (a) the use, presence, handling or disposition of
Hazardous Materials by Lessee, its employees, agents, contractors or invitees
in, on, under or about the Project or any part thereof, (b) the breach by
Lessee, its employees, agents, contractors or invitees of any of the terms of
this paragraph, and (c) any Hazardous Materials contamination of the Project or
any part thereof caused by Lessee, its employees, agents, contractors or
invitees. Lessee's obligations hereunder shall survive the termination of this
Lease for a period of five (5) years.

53.4  HAZARDOUS MATERIALS INDEMNIFICATION BY LESSOR

Lessor shall indemnify and hold Lessee, its officers, and employees, and 
Lessee's agents and invitees, harmless from all liability arising out of (i) the
presence of Hazardous Materials in, on, under or about the Project prior to the 
date hereof arising from the future release of Hazardous Materials by Lessor, 
its officers, employees, agents, contractors, in, under or about the Project, or
(ii) arising from the future release of Hazardous Material in, on, under or 
about the Premises by other Tenants in the Building, to the extent a prudent

Lessor represents and warrant to Lessee that to the best of its knowledge, 
without independent investigation, Lessor has no knowledge of, and has no reason
to believe that there has been, any release, generating, storage or use of 
Hazardous Materials in violation of applicable law on the Project as of the date
hereof. Lessor further agrees that it will not in the future, use, produce, 
generate or store any Hazardous Materials on the Project in violation of 
applicable laws.

Upon termination of this Lease, Lessee shall cause any and all Hazardous

2.   PREMISES.

     2.1  LETTING. Lessor hereby leases to Lessee, and Lessee hereby leases from
Lessor, the Premises, for the term, at the rental, and upon all of the terms,
covenants and conditions set forth in this Lease. Unless otherwise provided
herein, any statement of square footage set forth in this Lease, or that may
have been used in calculating rental, is an approximation which Lessor and
Lessee agree is reasonable and the rental based thereon is not subject to
revision whether or not the actual square footage is more or less.

     2.2  CONDITION. Lessor shall deliver the Premises to Lessee clean and free
of debris on the Commencement Date and warrants to Lessee that the existing
plumbing, fire sprinkler system, lighting, air conditioning, heating, and
loading doors, if any, in the Premises, other than those constructed by Lessee,
shall be in good operating condition on the Commencement Date. If a non-
compliance with said warranty exists as of the Commencement Date, Lessor shall,
except as otherwise provided in this Lease, promptly after receipt of written
notice from Lessee setting forth with specificity the nature and extent of such
non-compliance, rectify same at Lessor's expense. If Lessee does not give Lessor
written notice of a non-compliance with this warranty within thirty (30) days
after the Commencement Date, correction of that non-compliance shall be the
obligation of Lessee at Lessee's sole cost and expense.

     2.3  COMPLIANCE WITH COVENANTS, RESTRICTIONS AND BUILDING CODE. Lessor
warrants to Lessee that the improvements on the Premises comply with all
applicable covenants or restrictions of record and applicable building codes,
regulations and ordinances in effect on the Commencement Date. Said warranty
does not apply to the use to which Lessee will put the Premises or to any
Alterations or Utility Installations (as defined in Paragraph 7.3(a)) made or to
be made by Lessee. If the Premises do not comply with said warranty, Lessor
shall, except as otherwise provided in this Lease, promptly after receipt of
written notice from Lessee setting forth with specificity the nature and extent
of such non-compliance, rectify the same at Lessor's expense. If Lessee does not
give Lessor written notice of a non-compliance with this warranty within six (6)
months following the Commencement Date, correction of that non-compliance shall
be the obligation of Lessee at Lessee's sole cost and expense.

     2.4  ACCEPTANCE OF PREMISES. Lessee hereby acknowledges: (a) that it has
been advised by the Brokers to satisfy itself with respect to the condition of
the Premises (including but not limited to the electrical and fire sprinkler
systems, security, environmental aspects,

Item 1A is set forth on Page 1A attached hereto and incorporated herein by 
reference.

1A Guarantor. The obligations of the Lessee under this lease are to be 
guaranteed by Richard B. Moran, Chris Ursetta, Michael Stammire.

                                       2
<PAGE>
 
compliance with Applicable Law, as defined in Paragraph 6.3) and the present and
future suitability of the Premises for Lessee's intended use, (b) that Lessee
has made such investigation as it deems necessary with reference to such matters
and assumes all responsibility therefor as the same relate to Lessee's occupancy
of the Premises and/or the term of this Lease, and (c) that neither Lessor, nor
any of Lessor's agents, has made any oral or written representations or
warranties with respect to the same matters other than as set forth in this
Lease.

     2.5  LESSEE PRIOR OWNER/OCCUPANT. The warranties made by Lessor in this
Paragraph 2 shall be of no force or effect if immediately prior to the date set
forth in Paragraph 1.1 Lessee was the owner or occupant of the Premises. In such
event, Lessee shall, at Lessee's sole cost and expense, correct any non-
compliance of the Premises with said warranties.

3.   TERM.

     3.1  TERM. The Commencement Date, Expiration Date and Original Term of this
Lease are as specified in Paragraph 1.3.

     3.2  EARLY POSSESSION. If Lessee totally or partially occupies the Premises
prior to the Commencement Date, the obligation to pay Base Rent shall be rebated
for the period of such early possession. All other terms of this Lease, however,
shall be in effect during such period. Any such early possession shall not
affect nor advance the Expiration Date of the Original Term.

     3.3  DELAY IN POSSESSION. If for any reason Lessor cannot deliver
possession of the Premises to Lessee as agreed herein by the Early Possession
Date, if one is specified in paragraph 1.4, or if no Early Possession Date is
specified, by the Commencement Date, Lessor shall not be subject to any
liability therefor, nor shall such failure affect the validity of this Lease, or
the obligations of Lessee hereunder, or extend the term hereof, but in such
case, Lessee shall not, except as otherwise provided herein, be obligated to
pay rent or perform any other obligation of Lessee under the terms of this Lease
until Lessor delivers possession of the Premises to Lessee. If possession of the
Premises is not delivered to Lessee within sixty (60) days after the
Commencement Date, Lessee may, as its option, by notice in writing to Lessor
within ten (10) days thereafter, cancel this Lease. In which event the Parties
shall be discharged from all obligations hereunder; provided, however, that if
such written notice by Lessee is not received by Lessor within said ten (10) day
period, Lessee's right to cancel this Lease shall terminate and be of no further
force or effect. Except as may be otherwise provided, and regardless of when the
term actually commences, if possession is not tendered to Lessee when required
by this Lease and Lessee does not terminate this Lease, as aforesaid, the period
free of the obligation to pay Base Rent, if any, that Lessee would otherwise
have enjoyed shall run from the date of delivery of possession and continue for
a period equal to what Lessee would otherwise have enjoyed under the terms
hereof, but minus any days of delay caused by the acts, changes or omissions of
Lessee.

4.   RENT

     4.1  BASE RENT. Lessee shall cause payment of Base Rent and other rent or
charges as the same may be adjusted from time to time, to be received by Lessor
in lawful money of the United States, without offset or deduction, on or before
the day on which it is due under the terms of this Lease. Base Rent and all
other rent and charges for any period during the term hereof which is for less
than one (1) full calendar month shall be prorated based upon the actual number
of days of the calendar month involved. Payment of Base Rent and other charges
shall

                                       3
<PAGE>
 
be made to Lessor at its address stated herein or to such other persons or at
such other addresses as Lessor may from time to time designate in writing to
Lessee.

5.   SECURITY DEPOSIT.  Lessee shall deposit with Lessor upon execution hereof
the Security Deposit set forth in Paragraph 1.7 as security for Lessee's
faithful performance of Lessee's obligations under this Lease.  If Lessee fails
to pay Base Rent or other rent or charges due hereunder, or otherwise Defaults
under this Lease (as defined in paragraph 13.1), Lessor may use, apply or
retain all or any portion of said Security Deposit for the payment of any amount
due Lessor or to reimburse or compensate Lessor for any liability, cost,
expense, loss or damage (including attorneys' fees) which Lessor may suffer or
incur by reason thereof.  If Lessor uses or applies all or any portion of said
Security Deposit, Lessee shall within ten (10) days after written request
therefor deposit moneys with Lessor sufficient to restore said Security Deposit
to the full amount required by this Lease.  Any time the Base Rent increases
during the term of this Lease, Lessee shall; upon written request from Lessor,
deposit additional moneys with Lessor sufficient to maintain the same ratio
between the Security Deposit and the Base Rent as those amounts are specified in
the Basic Provisions.  Lessor shall not be required to keep all or any part of
the Security Deposit separate from its general accounts.  Lessor shall, at the
expiration or earlier termination of the term hereof and after Lessee has
vacated the Premises, return to Lessee (or, at Lessor's option, to the last
assignee, if any, of Lessee's interest herein), that portion of the Security
Deposit not used or applied by Lessor. Unless otherwise expressly agreed in
writing by lessor, no part of the Security Deposit shall be considered to be
held in trust to bear interest or other increment for its use, or to be
prepayment for any moneys to be paid by lessee under this Lease.

6.   USE.

     6.1  USE. Lessee shall use and occupy the Premises only for the purposes
set forth in paragraph 1.8, or any other use which is comparable thereto, and
for no other purpose. Lessee shall not use or permit the use of the Premises in
a manner that creates waste or a nuisance, or that disturbs owners and/or
occupants of, or causes damage to, neighboring premises or properties. Lessor
hereby agrees to not unreasonably withhold or delay its consent to any written
request by Lessee, Lessees assignees or subtenants, and by prospective assignees
and subtenants of the Lessee, its assignees and subtenants, for a modification
of said permitted purpose for which the premises may be used or occupied, so
long as the same will not impair the structural integrity of the improvements on
the Premises, the mechanical or electrical systems therein, is not significantly
more burdensome to the Premises and the improvements thereon, and is otherwise
permissible pursuant to this Paragraph 6. If Lessor elects to withhold such
consent, Lessor shall within five (5) business days give a written notification
of same, which notice shall include an explanation of Lessor's reasonable
objections to the change in use.

     6.2  HAZARDOUS SUBSTANCES.

          (a)  REPORTABLE USES REQUIRE CONSENT. The term "Hazardous Substance"
as used in this Lease shall mean any product, substance, chemical material or
waste whose presence, nature, quantity and/or intensity of existence, use,
manufacture, disposal, transportation, spill, release or effect, either by
itself or in combination with other materials expected to be on the Premises, is
either: (i) potentially injurious to the public health, safety or welfare, the
environment or the Premises, (ii) regulated or monitored by any governmental

                                       4
<PAGE>
 
authority, or (iii) a basis for liability of Lessor to any governmental agency
or third party under any applicable statute or common law theory.  Hazardous
SUBSTANCE shall include, but not be limited to, hydrocarbons, petroleum,
gasoline, crude oil or any products, by-products or fractions thereof.  Lessee
shall not engage in any activity in, on or about the Premises which constitutes
Reportable Use (as hereinafter defined) of Hazardous Substances without the
express prior written consent of Lessor and compliance in a timely manner
(at Lessee's sole cost and expense) with all Applicable Law (as defined in
paragraph 6.3).  "Reportable Use" shall mean (i) the installation or use of any
above or below ground storage tank, (ii) the generation, possession, storage,
use, transportation, or disposal of a Hazardous Substance that requires a permit
from, or with respect to which a report, notice, registration or business plan
is required to be filed with any governmental authority.  Reportable Use shall
also include Lessee's being responsible for the presence in, on or about the
Premises of a Hazardous Substance with respect to which any Applicable Law
requires that a notice be given to persons entering or occupying the Premises or
neighboring properties.  Notwithstanding the foregoing, Lessee may, without
Lessor's prior consent, but in compliance with all Applicable Law, use any
ordinary and customary materials reasonably required to be used by Lessee in the
normal course of Lessee's business permitted on the Premises, so long as such
use is not a Reportable Use and does not expose the Premises or neighboring
properties to any meaningful risk of contamination or damage or expose Lessor to
any liability therefor.  In addition, Lessor may (but without any obligation to
do so) condition its consent to the use or presence of any Hazardous Substance,
activity or storage tank by Lessee upon Lessee's giving Lessor such additional
assurances as Lessor, in its reasonable discretion, deems necessary to protect
itself, the public, the Premises and the environment against damage,
contamination or injury and/or liability therefrom or therefor, including, but
not limited to, the installation (and removal on or before Lease expiration or
earlier termination) of reasonably necessary protective modifications to the
Premises (such as concrete encasements) and/or the deposit of any additional
Security Deposit under Paragraph 5 hereof.

          (b)  DUTY TO INFORM LESSOR.  If Lessee knows, or has reasonable cause
to believe, that a Hazardous Substance, or a condition involving or resulting
from same, has come to be located in, on, under or about the Premises, other
than as previously consented to by lessor, Lessee shall immediately give written
notice of such fact to Lessor.  Lessee shall also immediately give Lessor a copy
of any statement, report, notice, registration, application, permit, business
plan, license, claim, action or proceeding given to, or received from, any
governmental authority or private party, or persons entering or occupying the
Premises, concerning the presence, spill, release, discharge of, or exposure to,
any Hazardous Substance or contamination in, on, or about the Premises,
including but not limited to all such documents as may be involved in any
Reportable Uses involving the Premises.

          (c)  INDEMNIFICATION. Lessee shall indemnify, protect, defend and hold
Lessor, its agents, employees, lenders and ground lessor, if any, and the
Premises, harmless from and against any and all loss of rents and/or damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, permits and
attorney's and consultant's fees arising out of or involving any Hazardous
Substance or storage tank brought onto the Premises by or for Lessee or under
Lessee's control. Lessee's obligations under this Paragraph 6 shall include, but
not be limited to, the effects of any contamination or injury to person,
property or the environment created or

                                       5
<PAGE>
 
suffered by Lessee, and the cost of investigation (including consultant's and
attorney's fees and testing), removal, remediation, restoration and/or abatement
thereof, or of any contamination therein involved, and shall survive the
expiration or earlier termination of this Lease. No termination, cancellation or
release agreement entered into by Lessor and Lessee shall release Lessee from
its obligations under this Lease with respect to Hazardous Substances or storage
tanks, unless specifically so agreed by lessor in writing at the time of such
agreement.

     6.3  LESSEE'S COMPLIANCE WITH LAW. Except as otherwise provided in this
Lease, Lessee, shall, at Lessee's sole cost and expense, fully, diligently and
in a timely manner, comply with all "Applicable Law," which term is used in this
Lease to include all laws, rules, regulations, ordinances, directives,
covenants, easements and restrictions of record, permits, the requirements of
any applicable fire insurance underwriter or rating bureau, and the
recommendations of Lessor's engineers and/or consultants, relating in any manner
to the Premises (including but not limited to matters pertaining to (i)
industrial hygiene, (ii) environmental conditions on, in, under or about the
Premises, including soil and groundwater conditions, and (iii) the use,
generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill or release of any Hazardous Substance or storage
tank), now in effect or which may hereafter come into effect, and whether or not
reflecting a change in policy from any previously existing policy. Lessee shall,
within five (5) days after receipt of Lessor's written request, provide Lessor
with copies of all documents and information, including, but not limited to,
permits, registrations, manifests, applications, reports and certificates,
evidencing Lessee's compliance with any Applicable Law specified by Lessor, and
shall immediately upon receipt, notify Lessor in writing (with copies of any
documents involved) of any threatened or actual claim, notice, citation,
warning, compliant or report pertaining to or involving failure by Lessee or the
Premises to comply with any Applicable Law.

     6.4  INSPECTION; COMPLIANCE. Lessor and Lessor's Lender(s) (as defined in
Paragraph 8.3(a)) shall have the right to enter the Premises at any time, in the
case of an emergency, and otherwise at reasonable times, for the purpose of
inspecting the condition of the Premises and for verifying compliance by Lessee
with this Lease and all Applicable Laws (as defined in paragraph 6.3), and to
employ experts and/or consultants in connection therewith and/or to advise
Lessor with respect to Lessee's activities, including but not limited to the
installation, operation, use, monitoring, maintenance, or removal of any
Hazardous Substance or storage tank on or from the Premises. The costs and
expenses of any such inspections shall be paid by the party requesting same,
unless a Default or Breach of this Lease, violation of Applicable Law, or a
contamination, caused or materially contributed to by Lessee is found to exist
or to be imminent, or unless the inspection is requested or ordered by a
governmental authority as the result of any such existing or imminent
violation or contamination. In any such case, Lessee shall upon request
reimburse Lessor or Lessor's Lender, as the case may be, for the costs and
expenses of such inspections.

Lessee's sole cost and expense and at all times, keep the Premises and every
part thereof in good order, condition and repair, (whether or not such portion
of the Premises requiring repair, or the means of repairing the same, are
reasonably or readily accessible to Lessee, and whether or not the need for such
repairs occurs as a result of Lessee's use, any prior use, the elements or the
age of such portion of the Premises), including, without limiting the generality

investigatory and/or remedial action reasonably recommended, whether or not
formally ordered or required, for the cleanup of any contamination of, and for
the maintenance, security and/or monitoring of, the Premises, the elements
surrounding same, or neighboring properties, that was caused or materially
contributed to by Lessee, or pertaining to or involving any Hazardous Substance
and/or storage tank brought onto the Premises by or for Lessee or under its
control. Lessee, in keeping the Premises in good order, condition and repair,
shall exercise and perform good maintenance practices. Lessee's obligations
shall include restorations, replacements or renewals when necessary to keep the
Premises and all improvements thereon or a part thereof in good order, condition
and state of repair.

          (b)  Lessee shall, at Lessee's sole cost and expense, procure and
maintain contracts, with copies to Lessor, in customary form and substance for,
and with contractors specializing and experienced in, the inspection,
maintenance and service of the following equipment and improvements, if any, and

     7.2  LESSOR'S OBLIGATIONS. Upon receipt of written notice of the need for
such repairs and subject to paragraph 13.5, Lessor shall, at Lessor's expense,
keep the foundations, exterior roof and structural aspects of the Premises in
good order, condition and repair, Lessor shall not, however, be obligated to

doors or plate glass or the interior surface of exterior walls. Lessor shall
not, in any event, have any obligation to make any repairs until Lessor receives
written

                                       7
<PAGE>
 
notice of the need for such repairs. It is the intention of the Parties that the
terms of this Lease govern the respective obligations of the Parties as to
maintenance and repair of the Premises. Lessee and Lessor expressly waive the
benefit of any statute now or hereafter in effect to the extent it is
inconsistent with the terms of this Lease with respect to, or which affords
Lessee the right to make repairs at the expense of Lessor or to terminate this
Lease by reason of, any needed repairs.

     7.3  UTILITY INSTALLATIONS; TRADE FIXTURES; ALTERATIONS.

          (a)  DEFINITIONS; CONSENT REQUIRED.  The term "Utility Installations"

power panels, electrical distribution, security fire protection systems,
communication systems, lighting fixtures, heating, ventilating, and air
conditioning equipment, plumbing, and fencing in, on or about the Premises.  The
term "Trade Fixtures" shall mean Lessee's machinery and equipment that can be

Utility Installations made by Lessee that are not yet owned by Lessor as defined
in paragraph 7.4(a).  Lessee shall not make any Alterations or Utility

consent.  Lessee may, however, make non-structural Utility Installations to the
interior of the Premises (excluding the roof), as long as they are not visible
from the outside, do not involve puncturing, relocating or removing the roof or
any existing walls, and the cumulative cost thereof during the term of this
Lease as extended does not exceed $25,000.

          (b)  CONSENT.  Any Alterations or Utility Installations that Lessee
shall desire to make and which require the consent of the Lessor shall be
presented to Lessor in written form with proposed detailed plains.  All consents
given by Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all applicable
permits required by governmental authorities, (ii) the furnishing of copies of
such permits together with a copy of the plans and specifications for the
Alteration or Utility installation to Lessor prior to commencement of the work
thereon, and (iii) the compliance by Lessee with all conditions of said permits
in a prompt and expeditious manner.  Any Alterations or Utility Installations by
Lessee during the term of this Lease shall be done in a good and workmanlike
manner, with good and sufficient materials, and in compliance with all
Applicable Law.  Lessee shall promptly upon completion thereof furnish Lessor
with as-built plans and specifications therefor.  Lessor may (but without
obligation to do so) condition its consent to any requested Alteration or
Utility Installation that costs $10,000 or more upon Lessee's providing Lessor
with a lien and completion bond in an amount equal to one and one-half times the
estimated cost of such Alteration or Utility Installation and/or upon Lessee's
posting an additional Security Deposit with Lessor under Paragraph 36 hereof.

          (c)  INDEMNIFICATION. Lessee shall pay, when due, all claims for labor
or materials furnished or alleged to have been furnished to or for Lessee at or
for use on the Premises, which claims are or may be secured by any mechanics' or
materialmen's lien against the Premises or any interest therein. Lessee shall
give Lessor not less than ten (10) days' notice

                                       8
<PAGE>
 
prior to the commencement of any work in, on or about the Premises, and Lessor
shall have the right to post notices of non-responsibility in or on the Premises
as provided by law. If Lessee shall, in good faith, contest the validity of any
such lien, claim or demand, then Lessee shall, at its sole expense defend and
protect itself, Lessor and the Premises against the same and shall pay and
satisfy any such adverse judgment that may be rendered thereon before the
enforcement thereof against the Lessor or the Premises. If Lessor shall require,
Lessee shall furnish to Lessor a surety bond satisfactory to Lessor in an amount
equal to one and one-half times the amount of such contested lien claim or
demand, indemnifying Lessor against liability for the same, as required by law
for the holding of the Premises free from the effect of such lien or claim. In
addition, Lessor may require Lessee to pay Lessor's attorney's fees and costs in
participating in such action if Lessor shall decide it is to its best interest
to do so.

     7.4  OWNERSHIP; REMOVAL; SURRENDER; AND RESTORATION.

          (a)  OWNERSHIP.  Subject to Lessor's right to require their removal or
become the owner thereof as hereinafter provided in this Paragraph 7.4, all
Alterations and Utility Additions made to the Premises by Lessee shall be the
property of and owned by Lessee, but considered a part of the Premises. Lessor
may, at any time and at its option, elect in writing to Lessee to be the owner
of all or any specified part of the Lessee Owned Alterations and Utility
Installations. Unless otherwise instructed per subparagraph 7.4(b) hereof, all
Lessee Owned Alterations and Utility Installations shall, at the expiration or
earlier termination of this Lease, become the property of Lessor and remain upon
and be surrendered by Lessee with the Premises.

          (b)  REMOVAL.  Unless otherwise agreed in writing, Lessor may require
that any or all Lessee Owned Alterations or Utility Installations be removed by
the expiration or earlier termination of this Lease, notwithstanding their
installation may have been consented to by Lessor.  Lessor may require the
removal at any time of all or any part of any Lessee Owned Alterations or
Utility Installations made without the required consent of Lessor.

          (c)  SURRENDER/RESTORATION. Lessee shall surrender the Premises by the
end of the last day of the Lease term or any earlier termination date, with all
of the improvements, parts and surfaces thereof clean and free of debris and in
good operating order, condition and state of repair, ordinary wear and tear
excepted. "Ordinary wear and tear" shall not include any damage or deterioration
that would have been prevented by good maintenance practice or by Lessee
performing all of its obligations under this Lease. Except as otherwise agreed
or specified in writing by Lessor, the Premises, as surrendered, shall include
the Utility Installations. The obligation of Lessee shall include the repair of
any damage occasioned by the installation, maintenance or removal of Lessee's
Trade Fixtures, furnishings, equipment, and Alterations and/or Utility
Installations, as well as the removal of any storage tank installed by or for
Lessee, and the removal, replacement, or remediation of any soil, material or
ground water contaminated by Lessee, all as may then be required by Applicable
Law and/or good service practice. Lessee's Trade Fixtures shall remain the
property of Lessee and shall be removed by Lessee subject to its obligation to
repair and restore the Premises per this Lease.

8.   INSURANCE INDEMNITY.

     8.1  PAYMENT OF PREMIUM INCREASES,

                                       9
<PAGE>
 
          (a) Lessee shall pay to Lessor any insurance cost increase ("Insurance
Cost Increase") occurring during the term of this Lease. "Insurance Cost
Increase" is defined as any increase in the actual cost of the insurance
required under Paragraphs 8.2(b), 8.3(a), and 8.3(b).  ("Required Insurance"),
over and above the Base Premium, as hereinafter defined, calculated on an annual
basis.  "Insurance Cost Increase" shall include, but not be limited to,
increases resulting from the nature of Lessee's occupancy, any act or omission
of Lessee, requirements of the holder of a mortgage or deed of trust covering
the Premises, increased valuation of the Premises, and/or a premium rate
increase.  If the parties insert a dollar amount in paragraph 19 such amount
shall be considered the "Base Premium."  In lieu thereof, if the Premises have
been previously occupied, the "Base Premium" shall be the annual premium
applicable to the most recent occupancy.  If the Premises have never been
occupied, the "Base Premium" shall be the lowest annual premium reasonably
obtainable for the Required Insurance as of the commencement of the Original
Term, assuming the most nominal use possible of the Premises.  In no event,
however, shall Lessee be responsible for any portion of the premium cost
attributable to liability insurance coverage in excess of $1,000,000 procured
under Paragraph 8.2(b) (Liability Insurance Carried by Lessor).

          (b) Lessee shall pay any such Insurance Cost Increase to Lessor within
thirty (30) days after receipt by Lessee of a copy of the premium statement or
other reasonable evidence of the amount due.  If the insurance policies
maintained hereunder cover other property besides the Premises, Lessor shall
also deliver to Lessee a statement of the amount of such Insurance Cost Increase
attributable only to the Premises showing in reasonable detail the manner in
which such amount was computed Premiums for policy periods commencing prior to,
or extending beyond, the term of this Lease shall be prorated to coincide with
the corresponding Commencement or Expiration of the Lease term.

     8.2  LIABILITY INSURANCE

          (a) CARRIED BY LESSEE.  Lessee shall obtain and keep in force during
the term of this Lease a Commercial General Liability policy of insurance
protecting Lessee and Lessor (as additional insured) against claims for bodily
injury, personal injury and property damage based upon involving or arising out
of the ownership, use, occupancy or maintenance of the Premises and all areas
appurtenant thereto.  Such insurance shall be on an occurrence basis providing
single limit coverage in an amount not less than $1,000,000 per occurrence with
an "Additional Insured-Managers or Lessors of Premises" Endorsement and contain
the "Amendment of the Pollution Exclusion" for damage caused by heat, smoke or
fumes from a hostile fire.  The policy shall not contain any intra-insured
exclusions as between insured persons or organizations, but shall include
coverage for liability assumed under this Lease as an "insured contract" for the
performance of Lessee's indemnity obligations under this Lease.  The limits of
said insurance required by this Lease or as carried by Lessee shall not,
however, limit the liability of Lessee nor relieve Lessee of any obligation
hereunder.  All insurance to be carried by Lessee shall be primary to and not
contributory with any similar insurance carried by Lessor, whose insurance shall
be considered excess insurance only.

          (b) CARRIED BY LESSOR.  In the event Lessor is the Insuring Party,
Lessor shall also maintain liability insurance described in Paragraph 8.2(a),
above, in addition to, and not in 

                                       10
<PAGE>
 
lieu of, the insurance required to be maintained by Lessee. Lessee shall not be
named as additional insured therein.

     8.3  PROPERTY INSURANCE-- BUILDING, IMPROVEMENTS AND RENTAL VALUE.

          (a)  BUILDING AND IMPROVEMENTS.  The Insuring Party shall obtain and
keep in force during the term of this Lease a policy or policies in the name of
Lessor, with loss payable to Lessor and to the holders of any mortgages, deeds
of trust or ground leases on the Premises ("Lender(s)"), insuring loss or damage
to the Premises. The amount of such insurance shall be equal to the full
replacement cost of the Premises, as the same shall exist from time to time, or
the amount required by Lenders, but in no event more than the commercially
reasonable and available insurable value thereof if, by reason of the unique
nature or age of the improvements involved, such latter amount is less than full
replacement cost. Lessee Owned Alterations and Utility Installations shall be
insured by Lessee under Paragraph 8.4. If the coverage is available and
commercially appropriate, such policy or policies shall insure against all risks
of direct physical loss or damage (except the perils of flood and/or earthquake
unless required by a Lender), including coverage for any additional costs
resulting from debris removal and reasonable amounts of coverage for the
enforcement of any ordinance or law regulating the reconstruction or replacement
of any undamaged sections of the Premises required to be demolished or removed
by reason of the enforcement of any building, zoning, safety or land use laws as
the result of a covered cause of loss, but not including plate glass insurance.
Said policy or policies shall also contain an agreed valuation provision in lieu
of any coinsurance clause, waiver of subrogation, and inflation guard protection
causing an increase in the annual property insurance coverage amount by a factor
of not less than the adjusted U.S. Department of Labor Consumer Price Index for
All Urban Consumers for the city nearest to where the Premises are located.

          (b)  RENTAL VALUE.  Lessor shall, in addition, obtain and keep in
force during the term of this Lease a policy or policies in the name of Lessor,
with loss payable to Lessor and Lender(s), insuring the loss of the full rental
and other charges payable by Lessee to Lessor under this Lease for one (1) year
(including all real estate taxes, insurance costs, and any scheduled rental
increases). Said insurance shall provide that in the event the Lease is
terminated by reason of an insured loss, the period of indemnity for such
coverage shall be extended beyond the date of the completion of repairs or
replacement of the Premises, to provide for one full year's loss of rental
revenues from the date of any such loss. Said insurance shall contain an agreed
valuation provision in lieu of any coinsurance clause, and the amount of
coverage shall be adjusted annually to reflect the projected rental income,
property taxes, insurance premium costs and other expenses, if any, otherwise
payable by Lessee, for the next twelve (12) month period.

          (c)  ADJACENT PREMISES.  If the Premises are part of a larger
building, or if the Premises are part of a group of buildings owned by Lessor
which are adjacent to the Premises, the Lessee shall pay for any increase in the
premiums for the property insurance of such building or buildings if said
increase is caused by Lessee's acts, omissions, use or occupancy of the Premise.

          (d)  TENANT'S IMPROVEMENTS.  Since Lessor is the Insuring Party, the
Lessor shall not be required to insure Lessee Owned Alterations and Utility
Installations unless the item in question has become the property of Lessor
under the terms of this Lease.

                                       11
<PAGE>
 
     8.4  LESSEE'S PROPERTY INSURANCE. Subject to the requirements of Paragraph
8.5, Lessee at its cost shall either by separate policy or, at Lessor's option,
by endorsement to a policy already carried, maintain insurance coverage on all
of Lessee's personal property, Lessee Owned Alterations and Utility
Installations in, on, or about the Premises similar in coverage to that carried
by the Insuring Party under Paragraph 8.3. Such insurance shall be full
replacement cost coverage with a deductible of not to exceed $1,000 per
occurrence. The proceeds from any such insurance shall be used by Lessee for the
replacement of personal property or the restoration of Lessee Owned Alterations
and Utility Installations. Lessee shall be in the Insuring Party with respect to
the insurance required by this Paragraph 8.4 and shall provide Lessor with
written evidence that such insurance is in force.

     8.5  INSURANCE POLICIES. Insurance required hereunder shall be in companies
duly licensed to transact business in the state where the Premises are located,
and maintaining during the policy term a "General Policy Holders Rating" of at
least B+, V, or such other rating as may be required by a Lender having a lien
on the Premises, as set forth in the most current issue of "Best's Insurance
Guide." Lessee shall not do or permit to be done anything which shall invalidate
the insurance policies referred to in this Paragraph 8. Lessee shall cause to be
delivered to Lessor certified copies of, or certificates evidencing the
existence and amounts of, the insurance, and with the additional insureds,
required under Paragraph 8.2(a) and 8.4. No such policy shall be cancelable or
subject to modification except after thirty (30) days prior written notice to
Lessor. Lessee shall at least thirty (30) days prior to the expiration of such
policies, furnish Lessor with evidence of renewals or "insurance binders"
evidencing renewal thereof, or Lessor may order such insurance and charge the
cost thereof to Lessee, which amount shall be payable by Lessee to Lessor upon
demand.

     8.6  WAIVER OF SUBROGATION. Without affecting any other rights or remedies,
Lessee and Lessor ("Waiving Party") each hereby release and relieve the other
and waive their entire right to recover damages (whether in contract or in tort)
against the other, for loss of or damage to the Waiving Party's property arising
out of or incident to the perils required to be insured against under Paragraph
8. The effect of such releases and waivers of the right to recover damages shall
not be limited by the amount of insurance carried or required, or by any
deductibles applicable thereto.

     8.7  INDEMNITY. Except for Lessor's negligence and/or breach of express
warranties, Lessee shall indemnify, protect, defend and hold harmless the
Premises, Lessor and its agents, Lessor's master or ground lessor, partners and
Lenders, from and against any and all claims, loss of rents and/or damages,
costs, liens, judgments, penalties, permits, attorney's and consultant's fees,
expenses and/or liabilities arising out of, involving, or in dealing with, the
occupancy of the Premises by Lessee, the conduct of Lessee's business, any act,
omission or neglect of Lessee, its agents, contractors, employees or invitees,
and out of any Default or Breach by Lessee in the performance in a timely manner
of any obligation on Lessee's part to be performed under this Lease. The
foregoing shall include, but not limited to, the defense or pursuit of any claim
or any action or proceeding involved therein, and whether or not (in the case of
claims made against Lessor) litigated and/or reduced to judgment, and whether
well founded or not. In case any action or proceeding be brought against Lessor
by reason of any of the foregoing matters, Lessee upon notice from Lessor shall
defend the same at Lessee's expense by counsel reasonably

                                       12
<PAGE>
 
satisfactory to Lessor and Lessor shall cooperate with Lessee in such defense.
Lessor need not have first paid any such claim in order to be so indemnified.

     8.8  EXEMPTION OF LESSOR FROM LIABILITY. Lessor shall not be liable for
injury or damage to the person or goods, wares, merchandise or other property of
Lessee, Lessee's employees, contractors, invitees, customers, or any other
person in or about the Premises, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, fire sprinklers, wires,
appliances, plumbing, air conditioning or lighting fixtures, or from any other
cause, whether the said injury or damage results from conditions arising upon
the Premises or upon other portions of the building of which the Premises are a
part, or from other sources or places, and regardless of whether the cause of
such damage or injury or the means of repairing the same is accessible or not.
Notwithstanding Lessor's negligence or breach of this Lease, Lessor shall under
no circumstances be liable for injury to Lessee's business or for any loss
of income or profit therefrom.

9.   DAMAGE OR DESTRUCTION.

     9.1  DEFINITIONS.

          (a)  "PREMISES PARTIAL DAMAGE" shall mean damage or destruction to the
improvements on the Premises, other than Lessee Owned Alterations and Utility
Installations, the repair cost of which damage or destruction is less than 50%
of the then Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land and Lessee
Owned Alterations and Utility installations.

          (b)  "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction to
the Premises, other than Lessee Owned Alterations and Utility Installations the
repair cost of which damage or destruction is 50% or more of the then
Replacement Cost of the Premises immediately prior to such damage or
destruction, excluding from such calculation the value of the land and Lessee
Owned Alterations and Utility Installations.

          (c)  "INSURED LOSS" shall mean damage or destruction to improvements
on the Premises, other than Lessee Owned Alterations and Utility Installations,
which was caused by an event required to be covered by the insurance described
in paragraph 8.3(a), irrespective of any deductible amounts or coverage limits
involved.

          (d)  "REPLACEMENT COST" shall mean the cost to repair or rebuild the
improvements owned by Lessor at the time of the occurrence to their condition
existing immediately prior thereto, including demolition, debris removal and
upgrading required by the operation of applicable building codes, ordinances or
laws, and without deduction for depreciation.

          (e)  "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or
discovery of a condition involving the presence of, or a contamination by, a
Hazardous Substance as defined in paragraph 6.2(a), in, on, or under the
Premises.

     9.2  PARTIAL DAMAGE-- INSURED LOSS. If a Premises Partial Damage that is an
Insured Loss occurs, then Lessor shall, at Lessor's expense, repair such damage
(but not Lessee's Trade Fixtures or Lessee Owned Alterations and Utility
Installations) as soon as reasonably possible and this Lease shall continue in
full force and effect. Notwithstanding the foregoing, if the required insurance
was not in force or the insurance proceeds are not sufficient to effect such
repair, the Insuring Party shall promptly contribute the shortage in proceeds
as and when required to complete said repairs. In the event however, the
shortage in proceeds was due to the

                                       13
<PAGE>
 
fact that, by reason of the unique nature of the improvements, full replacement
cost insurance coverage was not commercially reasonable and available, Lessor
shall have no obligation to pay for the shortage in insurance proceeds or to
fully restore the unique aspects of the Premises unless Lessee provides Lessor
with the funds to cover same, or adequate assurance thereof, within ten (10)
days following receipt of written notice of such shortage and request therefor.
If Lessor receives said funds or adequate assurance thereof within said ten (10)
day period, the party responsible for making the repairs shall complete them as
soon as reasonably possible and this Lease shall remain in full force and
effect. If Lessor does not receive such funds or assurance within said period,
Lessor may nevertheless elect by written notice to Lessee within ten (10) days
thereafter to make such restoration and repair as is commercially reasonable
with Lessor paying any shortage in proceeds, in which case this Lease shall
remain in full force and effect. If in such case Lessor does not so elect, then
this Lease shall terminate sixty (60) days following the occurrence of the
damage or destruction. Unless otherwise agreed, Lessee shall in no event have
any right to reimbursement from Lessor for any funds contributed by Lessee to
repair any such damage or destruction. Premises Partial Damage due to flood or
earthquake shall be subject to paragraph 9.3 rather than paragraph 9.2.
Notwithstanding that there may be some insurance coverage, but the net proceeds
of any such insurance shall be made available for the repairs if made by either
Party.

     9.3  PARTIAL DAMAGE--UNINSURED LOSS. If a Premises Partial Damage that is
not an Insured Loss occurs, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense and
this Lease shall continue in full force and effect, but subject to Lessor's
rights under Paragraph 13), Lessor may at Lessor's option, either: (i) repair
such damage as soon as reasonably possible at Lessor's expense, in which event
this Lease shall continue in full force and effect, or (ii) give written notice
to Lessee within thirty (30) days after receipt by Lessor of knowledge of the
occurrence of such damage of Lessor's desire to terminate this Lease as of the
date sixty (60) days following the giving of such notice. In the event Lessor
elects to give such notice of Lessor' intention to terminate this Lease, Lessee
shall have the right within ten (10) days after the receipt of such notice to
give written notice to Lessor of Lessee's commitment to pay for the repair of
such damage totally at Lessee's expense and without reimbursement from Lessor.
Lessee shall provide Lessor with the required funds within thirty (30) days
following Lessee's said commitment. In such event this Lease shall continue in
full force and effect, and Lessor shall proceed to make such repairs as soon as
reasonably possible and the required funds are available. If Lessee does not
give such notice and provide the funds or assurance thereof within the times
specified above, this Lease shall terminate as of the date specified in Lessor's
notice of Terminate.

     9.4  TOTAL DESTRUCTION. Notwithstanding any other provision hereof, if a
Premises Total Destruction occurs (including any destruction required by any
authorized public authority), this Lease shall terminate sixty (60) days
following the date of such Premises Total Destruction, whether or not the damage
or destruction is an Insured Loss or was caused by a negligent or willful act of
Lessee. In the event, however, that the damage or destruction was caused by
Lessee, Lessor shall have the right to recover Lessor's damages from Lessee
except as released and waived in paragraph 8.6.

                                       14
<PAGE>
 
     9.5  DAMAGE NEAR END OF TERM. If at any time during the last six (6) months
of the term of this Lease there is damage for which the cost to repair exceeds
one (1) month's Base Rent, whether or not an Insured Loss, Lessor may, at
Lessor's option, terminate this Lease effective sixty (60) days following the
date of occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within thirty (30) days after the date of occurrence 
of such damage. Provided, however, if Lessee at that time has an exercisable
option to extend this Lease or to purchase the Premises, then Lessee may
preserve this Lease by, within twenty (20) days following the occurrence of the
damage, or before the expiration of the time provided in such option for its
exercise, whichever is earlier ("Exercise Period"), (i) exercising such option
and (ii) providing Lessor with any shortage in insurance proceeds (or adequate
assurance thereof) to cover any shortage in insurance proceeds, Lessor shall, at
Lessor's expense repair such damage as soon as reasonably possible and this
Lease shall continue in full force and effect. If Lessee fails to exercise such
option and provide such funds or assurance during said Exercise Period, then
Lessor may at Lessor's option terminate this Lease as of the expiration of said
sixty (60) day period following the occurrence of such damage by giving written
notice to Lessee of Lessor' election to do so within ten (10) days after the
expiration of the Exercise Period, notwithstanding any term or provision in the
grant of option to the contrary.

     9.6  ABATEMENT OF RENT; LESSEE'S REMEDIES.

          (a) In the event of damage described in paragraph 9.2 (Partial Damage-
- -Insured), whether or not Lessor or Lessee repairs or restores the Premises, the
Base Rent, Real Property Taxes, insurance premiums, and other charges, if any,
payable by Lessee hereunder for the period during which such damage, its repair
or the restoration continues (not to exceed the period for which rental value
insurance is required under Paragraph 8.3(b)), shall be abated in proportion to
the degree to which Lessee's use of the Premises is impaired.  Except for
abatement of Base Rent, Real Property Taxes, insurance premiums, and other
charges, if any, as aforesaid, all other obligations of Lessee hereunder shall
be performed by Lessee, and Lessee shall have no claim against Lessor for any
damage suffered by reason of any such repair or restoration.

          (b) If Lessor shall be obligated to repair or restore the Premises
under the provisions of this paragraph 9 and shall not commence, in a
substantial and meaningful way, the repair or restoration of the Premises within
ninety (90) days after such obligation shall accrue, Lessee may , at any time
prior to the commencement of such repair or restoration, give written notice to
Lessor and to any Lenders of which Lessee has actual notice of Lessee's election
to terminate this Lease on a date not less than sixty (60) days following the
giving of such notice.  If Lessee give such notice to Lessor and such Lenders
and such repair or restoration is not commenced within thirty (30) days after
receipt of such notice, this Lease shall terminate as of the date specified in
said notice.  If Lessor or a Lender commences the repair or restoration of the
Premises within thirty (30) days after receipt of such notice, this Lease shall
continue in full force and effect.  "Commence" as used in this Paragraph shall
mean either the unconditional authorization of the preparation of the required
plans, or the beginning of the actual work on the Premises, whichever first
occurs.

     9.7  HAZARDOUS SUBSTANCE CONDITIONS. If a Hazardous Substance Condition
occurs, unless Lessee is legally responsible therefor (in which case Lessee
shall make the investigation and remediation thereof required by Applicable Law
and this Lease shall continue in full force and

                                       15
<PAGE>
 
effect, but subject to Lessor's rights under Paragraph 13), Lessor may at
Lessor's option either (i) investigate and remediate such Hazardous Substance
Condition, if required, as soon as reasonably possible at Lessor's expense, in
which event this Lease shall continue in full force and effect, or (ii) if the
estimated cost to investigate and remediate such condition exceeds twelve (12)
times the then monthly Base Rent or $100,000, whichever is greater, given
written notice to Lessee within thirty (30) days after receipt by Lessor of
knowledge of the occurrence of such Hazardous Substance Condition of Lessor's
desire to terminate this Lease as of the ate sixty (60) days following the
giving of such notice. In the event Lessor elects to give such notice of
Lessor's intention to terminate this Lease, Lessee shall have the right within
ten (10) days after the receipt of such notice to give written notice to Lessor
of Lessee's commitment to pay for the investigation and remediation of such
hazardous Substance Condition totally at Lessee's expense and without
reimbursement from Lessor except to the extent of an amount equal to twelve (12)
times the then monthly Base Rent or $100,000, whichever is greater. Lessee shall
provide Lessor with the funds required of Lessee or satisfactory assurance
thereof within thirty (30) days following Lessee's said commitment. In such
event this Lease shall continue in full force and effect and Lessor shall
proceed to make such investigation and remediation as soon as reasonably
possible and the required funds are available. If Lessee does not give such
notice and provide the required funds or assurance thereof within the times
specified above, this Lease shall terminate as of the date specified in Lessor's
notice of termination. If a Hazardous Substance Condition occurs for which
Lessee is not legally responsible, there shall be abatement of Lessee's
obligations under this Lease to the same extent as provided in Paragraph 9.6(a)
for a period of not to exceed twelve (12) months.

     9.8   TERMINATION--ADVANCE PAYMENTS. Upon termination of this Lease
pursuant to this Paragraph 9, an equitable adjustment shall be made concerning
advance Base Rent and any other advance payments made by Lessee to Lessor.
Lessor shall, in addition, return to Lessee so much of Lessee's Security Deposit
as has not been, or is not then required to be, used by Lessor under the terms
of this Lease.

     9.9   WAIVE STATUTES. Lessor and Lessee agree that the terms of this Lease
shall govern the effect of any damage to or destruction of the Premises with
respect to the termination of this Lease and hereby waive the provisions of any
present or future statute to the extent inconsistent herewith.

10.  REAL PROPERTY TAXES.

     10.1  (a)  PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, as
defined in paragraph 10.2, applicable to the Premises; provided, however that
Lessee shall pay, in addition to rent, the amount, if any, by which Real
Property Taxes applicable to the Premises increase over the fiscal tax year
during which the Commencement Date occurs ("Tax Increase"). Subject to Paragraph
10.1(b), payment of any such Tax Increase shall be made by Lessee within thirty
(30) days after receipt of Lessor's written statement setting forth the amount
due and the computation thereof. Lessee shall promptly furnish Lessor with
satisfactory evidence that such taxes have been paid. If any such taxes to be 
paid by Lessee shall cover any period of time prior to or after the expiration 
or earlier termination of the term hereof, Lessee's share of such taxes shall be
equitably prorated to cover only the period of time within the tax fiscal year 
this Lease is in effect, and Lessor shall reimburse Lessee for any overpayment 
after such proration.

           (b)  ADVANCE PAYMENT.  In order to insure payment when due and before
delinquency of any or all Real Property Taxes, Lessor reserves the right, at
Lessor's option, to estimate the current Real Property Taxes applicable to the
Premises, and to require such current year's 

                                       16
<PAGE>
 
Tax Increase to be paid in advance to Lessor by Lessee, either: (i) in a lump
sum amount equal to the amount due, at least twenty (20) days prior to the
applicable delinquency date, or (ii) monthly in advance with the payment of the
Base Rent. If Lessor elects to require payment monthly in advance, the monthly
payment shall be that equal monthly amount which, over the number of months
remaining before the month in which the applicable tax installment would become
delinquent (and without interest thereon), would provide a fund large enough to
fully discharge before delinquency the estimated Tax Increase to be paid. When
the actual amount of the applicable Tax Increase is known, the amount of such
equal monthly advance payment shall be adjusted as required to provide the fund
needed to pay the applicable Tax Increase before delinquency. If the amounts
paid to Lessor by Lessee under the provisions of this Paragraph are insufficient
to discharge the obligations of Lessee to pay such Tax Increase as the same
becomes due, Lessee shall pay to Lessor, upon Lessor's demand, such additional
sums as are necessary to pay such obligation. All moneys paid to Lessor under
this paragraph may be intermingled with other moneys of Lessor and shall not
bear interest. In the event of a Breach by Lessee in the performance of the
obligations of Lessee under this Lease, then any balance of funds paid to Lessor
under the provisions of this Paragraph may, subject to proration as provided in
paragraph 10.1(a), at the option of Lessor, be treated as an additional Security
Deposit under Paragraph 5.

           (c)  ADDITIONAL IMPROVEMENTS.  Notwithstanding Paragraph 10.1(a)
hereof, Lessee shall pay to Lessor upon demand therefor the entirety of any
increase in Real Property Taxes assessed by reason of Alterations or Utility
Installations placed upon the Premises by Lessee or at Lessee's request.

     10.2  DEFINITION OF "REAL PROPERTY TAXES." As used herein, the term "Real
Property Taxes" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed upon the Premises by any authority
having the direct or indirect power to tax, including any city, state or federal
government, or any school, agricultural, sanitary, fire, street, drainage, or
other improvement district thereof, levied against any legal or equitable
interest of Lessor in the Premises or in the real property of which the Premises
are a part, Lessor's right to rent or other income therefrom, and/or Lessor's
business of leasing the Premises. The term "Real Property Taxes" shall also
include any tax, fee, levy assessment or charge, or any increase therein, in the
ownership of the Premises or in the improvements thereon, the execution of this
Lease, or any modification, amendment or transfer thereof, and whether or not
contemplated by the Parties.

     10.3  JOINT ASSESSMENT. If the Premises are not separately assessed.
Lessee's liability shall be an equitable proportion of the Real Property Taxes
for all of the land and improvements included within the tax parcel assessed,
such proportion to be determined by Lessor from the respective valuations
assigned in the assessor's work sheets or such other information as may be
reasonably available.  Lessor's reasonable determination thereof, in good faith,
shall be conclusive.

     10.4  PERSONAL PROPERTY TAXES. Lessee shall pay prior to delinquency all
taxes assessed against and levied upon Lessee Owned Alterations, Utility
Installations, Trade Fixtures, furnishings, equipment and all personal property
of Lessee contained in the Premises or elsewhere. When possible, Lessee shall
cause its Trade Fixtures, furnishings, equipment and all

                                       17
<PAGE>
 
other personal property to be assessed and billed separately from the real
property of Lessor. If any of Lessee's said personal property shall be assessed
with Lessor's real property, Lessee shall pay Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property or, at Lessor's option, as provided in
Paragraph 10.1(b).

11.  UTILITIES.  Lessee shall pay for all water, gas, heat, light, power,
telephone, trash disposal and other utilities and services supplied to the
Premises, together with any taxes thereon.  If any such services are not
separately metered to Lessee, Lessee shall pay a reasonable proportion, to be
determined by Lessor, of all charges jointly metered with other premises.

12.  ASSIGNMENT AND SUBLETTING.

     12.1  LESSOR'S CONSENT REQUIRED.

           (a) Lessee shall not voluntarily or by operation of law assign,
transfer, mortgage or otherwise transfer or encumber (collectively,
"assignment") or sublet all or any part of Lessee's interest in this Lease or in
the Premises without Lessor's prior written consent given under and subject to
the terms of Paragraph 36.

           (b) A change in the control of Lessee shall constitute an assignment
requiring Lessor's consent.  The transfer, on a cumulative basis, of fifty
percent (50%) or more of the voting control of Lessee shall  constitute a change
in control for this purpose.

           (c) The involvement of Lessee or its assets in any transaction, or
series of transactions (by way of merger, sale, acquisition, financing,
refinancing, transfer, leveraged buy-out or otherwise), whether or not a formal
assignment or hypothecation of this Lease or Lessee's assets occurs, which
results or will result in a reduction of the Net Worth of Lessee, as hereinafter
defined, by an amount equal to or greater than twenty-five percent (25%) of such
Net Worth of Lessee as it was represented to Lessor at the time of the execution
by Lessor of this Lease or at the time of the most recent assignment to which
Lessor has consented, or as it exists immediately prior to said transaction or
transactions constituting such reduction, at whichever time said Net Worth of
Lessee was or is greater, shall be considered an assignment of this Lease by
Lessee to which Lessor may reasonably withhold its consent.  "Net Worth of
Lessee" for purposes of this Lease shall be the net worth of Lessee (excluding
any guarantors) established under generally accepted accounting principles
consistently applied.

           (d) An assignment or subletting of Lessee's interest in this Lease
without Lessor's specific prior written consent shall, at Lessor's option, be a
Default curable after notice per Paragraph 13.1(c), or a noncurable Breach
without the necessity of any notice and grace period.  If Lessor elects to treat
such unconsented to assignment or subletting as a noncurable Breach, Lessor
shall have the right to either (i) terminate this Lease, or (ii) upon thirty
(30) days written notice ("Lessor's Notice"), increase the monthly Base Rent to
fair market rental value or one hundred ten percent (110%) of the Base Rent then
in effect, whichever is greater.  Pending determination of the new fair market
rental value, if disputed by Lessee, Lessee shall pay the amount set forth in
Lessor's Notice, with any overpayment credited against the next installment(s)
of Base Rent coming due, and any underpayment for the period retroactively to
the effective date of the adjustment, (i) the purchase price of any option to
purchase the Premises held by Lessee shall be subject to similar adjustment to
the then fair market value (without the Lease being considered an encumbrance or
any deduction for depreciation or obsolescence, and 

                                       18
<PAGE>
 
considering the Premises at its highest and best use and in good condition), or
one hundred ten percent (110%) of the price previously in effect, whichever is
greater, (ii) any index-oriented rental or price adjustment formulas contained
in this Lease shall be adjusted to require that the base index be determined
with reference to the index applicable to the time of such adjustment, and (iii)
any fixed rental adjustments scheduled during the remainder of the Lease term
shall be increased in the same ratio as the new market rental bears to the Base
Rent in effect immediately prior to the market value adjustment.

           (e) Lessee's remedy for any breach of this Paragraph 12.1 by Lessor
shall be limited to compensatory damages and injunctive relief.

     12.2  TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

           (a) Regardless of Lessor's consent, any assignment or subletting
shall not: (i) be effective without the express written assumption by such
assignee or sublessee of the obligations of Lessee under this Lease, (ii)
release Lessee of any obligations hereunder, or (iii) alter the primary
liability of Lessee for the payment of Base Rent and other sums due Lessor
hereunder or for the performance of any other obligations to be performed by
Lessee under this Lease.

           (b) Lessor may accept any rent or performance of Lessee's obligations
from any person other than Lessee pending approval or disapproval of an
assignment.  Neither a delay in the approval or disapproval of such assignment
nor the acceptance of any rent or performance shall constitute a waiver or
estoppel of Lessor's right to exercise its remedies for the Default or Breach by
Lessee of any of the terms, covenants or conditions of this Lease.

           (c) The consent of Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee.
However, Lessor may consent to subsequent sublettings and assignments of the
sublease or any amendments or modifications thereto without notifying Lessee or
anyone else liable on the Lease or sublease and without obtaining their consent,
and such action shall not relieve such persons from liability under this Lease
or sublease.

           (d) In the event of any Default or Breach of Lessee's obligations
under this Lease, Lessor may proceed directly against Lessee, any Guarantors or
any one else responsible for the performance of the Lessee`s obligations under
this Lease, including the sublessee, without first exhausting Lessor's remedies
against any other person or entity responsible therefor to Lessor, or any
security held by Lessor or Lessee.

           (e) Each request for consent to an assignment or subletting shall be
in writing, accompanied by information relevant to Lessor's determination as to
the financial and operational responsibility and appropriateness of the proposed
assignee or sublessee, including but not limited to the intended use and/or
required modification of the Premises, if any, together with a non-refundable
deposit of $1,000 or ten percent (10%) of the current monthly Base Rent,
whichever is greater, as reasonable consideration for Lessor's considering and
processing the request for consent.  Lessee agrees to provide Lessor with such
other or additional information and/or documentation as may be reasonably
requested by Lessor.

           (f) Any assignee of, or sublessee under, this Lease shall, by reason
of accepting such assignment or entering into such sublease, be deemed, for the
benefit of Lessor, to 

                                       19
<PAGE>
 
have assumed and agreed to conform and comply with each and every term,
covenant, condition and obligation herein to be observed or performed by Lessee
during the term of said assignment or sublease, other than such obligations as
are contrary to or inconsistent with provisions of any assignment or sublease to
which Lessor has specifically consented in writing.

           (g) Lessor, as a condition to giving its consent to any assignment or
subletting, may require that the amount and adjustment structure of the rent
payable under this Lease be adjusted to what is then the market value and/or
adjustment structure for property similar to the Premises as then constituted.

     12.3  ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. The
following terms and conditions shall apply to any subletting by Lessee of all or
any part of the Premises and shall be deemed included in all subleases under
this Lease whether or not expressly incorporated therein:

           (a) Lessee hereby assigns and transferees to Lessor all of Lessee's
interest in all rentals and income arising from any sublease of all or a portion
of the Premises heretofore or hereafter made by Lessee, and Lessor may collect
such rent and income and apply same toward Lessee's obligations under this
Lease; provided, however, that until a Breach (as defined in Paragraph 13.1)
shall occur in the performance of Lessee's obligations under this Lease, Lessee
may, except as otherwise provided in this Lease, receive, collect and enjoy the
rents accruing under such sublease. Lessor shall not, by reason of this or any
other assignment of such sublease to Lessor, nor by reason of the collection of
the rents from a sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a Breach
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents and other charges due and to become due under the sublease.
Sublessee shall rely upon any such statement and request from Lessor and shall
pay such rents and other charges to Lessor without any obligation or right to
inquire as to whether such Breach exists and notwithstanding any notice from or
claim from Lessee to the contrary. Lessee shall have no right or claim against
said sublessee, or, until the Breach has been cured, against Lessor for any such
rents and other charges to paid by said sublessee to Lessor.

           (b) In the event of a Breach by Lessee in the performance of its
obligations under this Lease, at its option and without any obligation to do so,
may require any sublessee to attorn to Lessor, in which event Lessor shall
undertake the obligations of the sublessor under such sublease from the time of
the exercise of said option to the expiration of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to such sublessor or for any other prior Defaults or
Breaches of such sublessor under such sublease.

           (c) Any matter or thing requiring the consent of the sublessor under
a sublease shall also require the consent of Lessor herein.

           (d) No sublessee shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

           (e) Lessor shall deliver a copy of any notice of Default or Breach by
Lessee to the sublessee, who shall have the right to cure the Default of Lessee
within the grace period, if 

                                       20
<PAGE>
 
any, specified in such notice. The sublessee shall have a right of reimbursement
and offset from and against Lessee for any such Defaults cured by the sublessee.

13.  DEFAULT; BREACH, REMEDIES.

     13.1  DEFAULT; BREACH. Lessor and Lessee agree that if an attorney is
consulted by Lessor in connection with a Lessee Default or Breach (as
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence
for legal services and costs in the preparation and service of a notice of
Default, and that Lessor may include the cost of such services and costs in said
notice as rent due and payable to cure said Default. A "Default" is defined as a
failure by the Lessee to observe, comply with or perform any of the terms,
covenants, conditions or rules applicable to Lessee under this Lease. A "Breach"
is defined as the occurrence of any one or more of the following Defaults, and,
where a grace period for cure after notice is specified herein, the failure by
Lessee to cure such Default prior to the expiration of the applicable grace
period, shall entitle Lessor to pursue the remedies set forth in Paragraphs 13.2
and/or 13.3:

           (a) The vacating of the Premises without the intention to reoccupy
same, or the abandonment of the Premises.

           (b) Except as expressly otherwise provided in this Lease, the failure
by Lessee to make any payment of Base Rent or any other monetary payment
required to be made by Lessee hereunder, whether to Lessor or to a third party,
as and when due, the failure by Lessee to provide Lessor with reasonable
evidence of insurance or surety bond required under this Lease, or the failure
of Lessee to fulfill any obligation under this Lease which endangers or
threatens life or property, where such failure continues for a period of three
(3) days following written notice thereof by or on behalf of Lessor to Lessee.

           (c) Except as expressly otherwise provided in this Lease, the failure
by Lessee to provide Lessor with reasonable written evidence (in duly executed
original form, if applicable) of (i) compliance with applicable law per
Paragraph 6.3, (ii) the inspection, maintenance and service contracts required
under Paragraph 7.1(b), (iii) the rescission of an unauthorized assignment or
subletting per Paragraph 12.1(b), (iv) a Tenancy Statement per Paragraphs 16 or
37, (v) the subordination or non-subordination of this Lease per Paragraph 30,
(vi) the guaranty of the performance of Lessee's obligations under this Lease if
required under Paragraphs 1.11 and 37, (vii) the execution of any document
requested under Paragraph 42 (easements), or (viii) any other documentation or
information which Lessor may reasonably require of Lessee under the terms of
this Lease, where any such failure continues for a period of ten (10) days
following written notice by or on behalf of Lessor to Lessee.

           (d) A Default by Lessee as to the terms, covenants, conditions or
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof,
that are to be observed, complied with or performed by Lessee, other than those
described in subparagraphs (a), (b) or (c), above, where such Default continues
for a period of thirty (30) days after written notice thereof by or on behalf of
Lessor to Lessee; provided, however, that if the nature of Lessee's Default is
such that more than thirty (30) days are reasonably required for its cure, then
it shall not be deemed to be a Breach of this Lease by Lessee if Lessee
commences such cure within said thirty (30) day period and thereafter diligently
prosecutes such cure to completion.

           (e) The occurrence of any of the following events:  (i) The making by
lessee of any general arrangement or assignment for the benefit of creditors;
(ii) Lessee's becoming a 

                                       21
<PAGE>
 
"debtor" as defined in 11 U.S.C. (S)101 or any successor statute thereto
(unless, in the case of a petition filed against Lessee, the same is dismissed
within sixty (60) days); (iii) the appointment of a trustee or receiver to take
possession of substantially all of Lessee's assets located at same is dismissed
within sixty (60) days; (iii) the appointment of a trustee or receiver to take
possession of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where possession is not restored to Lessee
within thirty (30) days; or (iv) the attachment, execution or other judicial
seizure of substantially all of Lessee's assets located at the Premises or of
Lessee's interest in this Lease, where such seizure is not discharged within
thirty (30) days; provided, however, in the event that any provision of this
subparagraph (e) is contrary to any applicable law, such provision shall be of
no force or effect, and not affect the validity of the remaining provisions.

           (f) The discovery by Lessor that any financial statement given to
Lessor by Lessee or any Guarantor of Lessee's obligations hereunder was
materially false.

           (g) If the performance of Lessee's obligations under this Lease is
guaranteed:  (i) the death of a guarantor, (ii) the termination of a guarantor's
liability with respect to this Lease other than in accordance with the terms of
such guaranty, (iii) a guarantor's becoming insolvent or the subject of a
bankruptcy filing, (iv) a guarantor's refusal to honor the guaranty, or (v) a
guarantor's breach of its guaranty obligation on an anticipatory breach basis,
and Lessee's failure, within sixty (60) days following written notice by or on
behalf of Lessor to Lessee of any such event, to provide Lessor with written
alternative assurance or security, which, when coupled with the then existing
resources of Lessee, equals or exceeds the combined financial resources of
Lessee and the guarantors that existed at the time of execution of this Lease.

     13.2  REMEDIES. If Lessee fails to perform any affirmative duty or
obligation of Lessee under this Lease, within ten (10) days after written notice
to Lessee (or in case of an emergency, without notice), Lessor may at its option
(but without obligation to do so), perform such duty or obligation on Lessee's
behalf, including but not limited to the obtaining of reasonably required bonds,
insurance policies, or governmental licenses, permits or approvals. The costs
and expenses of any such performance by Lessor shall be due and payable by
Lessee to Lessor upon invoice therefor. If any check given to Lessor by Lessee
shall not be honored by the bank upon which it is drawn, Lessor, at its option,
may require all future payments to be made under this Lease by Lessee to be made
only by cashier's check. In the event of a Breach of this Lease by Lessee, as
defined in Paragraph 13.1, with or without further notice or demand, and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such Breach, Lessor may:

           (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor.  In
such event Lessor shall be entitled to recover from Lessee:  (i) the worth at
the time of the award of the unpaid rent which had been earned at the time of
termination; (ii) the worth at the time of award of the amount by which the
unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that the Lessee proves could have
been reasonably 

                                       22
<PAGE>
 
avoided; (iii) the worth at the time of award of the amount by which the unpaid
rent for the balance of the term after the time of award exceeds the amount of
such rental loss that the Lessee proves could be reasonably avoided; and (iv)
any other amount necessary to compensate Lessor for all the detriment
proximately caused by the Lessee's failure to perform its obligations under this
Lease or which in the ordinary course of things would be likely to result
therefrom, including but not limited to the cost of recovering possession of the
Premises, expenses of reletting, including necessary renovation and alteration
of the Premises, reasonable attorneys' fees, and that portion of the leasing
commission paid by Lessor applicable to the unexpired term of this Lease. The
worth at the time of award of the amount referred to in provision (iii) of the
prior sentence shall be computed by discounting such amount at the discount rate
of the Federal Reserve Bank of San Francisco at the time of award plus one
percent (1%). Efforts by Lessor to mitigate damages caused by Lessee's Default
or Breach of this Lease shall not waive Lessor's right to recover damages under
this Paragraph. If termination of this Lease is obtained through the provisional
remedy of unlawful detainer, Lessor shall have the right to recover in such
proceeding the unpaid rent and damages as are recoverable therein, or Lessor may
reserve therein the right to recover all or any part thereof in a separate suit
for such rent and/or damages. If a notice and grace period required under
subparagraphs 13.1(b), (c) or (d) was not previously given, a notice to pay rent
or quit, or to perform or quit, as the case may be, given to Lessee under any
statute authorizing the forfeiture of leases for unlawful detainer shall also
constitute the applicable notice for grace period purposes required by
subparagraphs 13.1(b), (c) or (d). In such case, the applicable grace period
under subparagraphs 13.1(b), (c) or (d) and under the unlawful detainer statute
shall run concurrently after the one such statutory notice, and the failure of
Lessee to cure the Default within the greater of the two such grace periods
shall constitute both an unlawful detainer and a Breach of this Lease entitling
Lessor to the remedies provided for in this Lease and/or by said statute.

           (b) Continue the Lease and Lessee's right to possession in effect (in
California under California Civil Code Section 1951.4) after Lessee's Breach and
abandonment and recover the rent as it becomes due, provided Lessee has the
right to sublet or assign, subject only to reasonable limitations.  See
Paragraphs 12 and 36 for the limitations on assignment and subletting which
limitations Lessee and Lessor agree are reasonable.  Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver to
protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

           (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located.

           (d) The expiration or termination of this Lease and/or the
termination of Lessee's right to possession shall not relieve Lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

     13.3  INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus,
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions," shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach of this Lease by Lessee,

                                       23
<PAGE>
 
as defined in Paragraph 13.1, any such Inducement Provision shall automatically
be deemed deleted from this Lease and of no further force or effect, and any
rent, other charge, bonus, inducement or consideration theretofore abated, given
or paid by Lessor under such an Inducement Provision shall be immediately due
and payable by Lessee to Lessor, and recoverable by Lessor as additional rent
due under this Lease, notwithstanding any subsequent cure of said Breach by
Lessee. The acceptance by Lessor of rent or the cure of the Breach which
initiated the operation of this Paragraph shall not be deemed a waiver by Lessor
of the provisions of this Paragraph unless specifically so stated in writing by
Lessor at the time of such acceptance.

     13.4  LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and other sums due hereunder will cause Lessor to incur costs
not contemplated by this Lease, the exact amount of which will be extremely
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or trust deed covering the Premises.
Accordingly, if any installment of rent or any other sum due from Lessee shall
not be received by Lessor or Lessor's designee within five (5) days after such
amount shall be due, then, without any requirement for notice to Lessee, Lessee
shall pay to Lessor a late charge equal to six percent (6%) of such overdue
amount. The parties hereby agree that such late charge represents a fair and
reasonable estimate of the costs Lessor will incur by reason of late payment by
Lessee. Acceptance of such late charge by Lessor shall in no event constitute a
waiver of Lessee's Default or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4.1 of any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance.

     13.5  BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails within a reasonable time to perform an obligation required
to be performed by Lessor.

14.  CONDEMNATION.  If  the Premises or any portion thereof are taken under the
power of eminent domain or sold under the threat of the exercise of said power
(all of which are herein called "condemnation"), this Lease shall terminate as
to the part so taken as to the date the condemning authority takes title or
possession, whichever first occurs.  If more than the ten percent (10%) of the
floor area of the Premises, or more than twenty-five percent (25%) of the land
area not occupied by any building, is taken by condemnation, Lessee may, at
Lessee's option to be exercised in writing within ten (10) days after Lessor
shall have given Lessee written notice of such taking (or in the absence of such
notice, within ten (10) days after the condemning authority shall have taken
possession) terminate this Lease as the date the condemning authority takes such
possession.  If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion of
the Premises remaining, except that the Base Rent shall be reduced in the same
proportion as the renewable floor area of the Premises taken bears to the total
renewable floor area of the building located on the Premises.  No reduction of
Base Rent shall occur if the only portion of the Premises taken is land on which
there is no building.  Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the 

                                       24
<PAGE>
 
property of Lessor, whether such award shall be made as compensation for
diminution in value of the leasehold or for the taking of the fee, or as
severance damages; provided, however, that Lessee shall be entitled to any
compensation separately awarded to Lessee or Lessee's relocation expenses and/or
loss of Lessee's Trade Fixtures. In the event that this Lease is not terminated
by reason of such condemnation, Lessor shall to the extent of its net severance
damages received over and above the legal and other expenses incurred by Lessor
in the condemnation matter, repair any damage to the Premises caused by such
condemnation, except to the extent that Lessee has been reimbursed therefor by
the condemning authority. Lessee shall be responsible for the payment of any
amount in excess of such net severance damages required to complete such repair.

15.  BROKER'S FEE

     15.1  The Brokers named in Paragraph 1.10 are the procuring causes of this
Lease.

     15.2  Upon execution of this Lease by both Parties, Lessor shall pay to
said Brokers jointly, or in such separate shares as they may mutually designate
in writing, a fee as set forth in a separate written agreement between Lessor
and said Brokers (or in the event there is no separate written agreement between
Lessor and said Brokers, the sum of $ per agreed schedule) for brokerage
services rendered by said Brokers to Lessor in this transaction.

     15.3  Unless Lessor and Brokers have otherwise agreed in writing, Lessor
further agrees that: (a) if Lessee exercises any Option (as defined in Paragraph
39.1) or any Option subsequently granted to Lessee in this Lease, or (b) if
Lessee acquires any rights to the Premises or other premises described in this
Lease which are substantially similar to what Lessee would have acquired had an
Option herein granted to Lessee been exercised, or (c) if Lessee remains in
possession of the Premises, with the consent of Lessor, after the expiration of
the term of this Lease after having failed to exercise an Option, or (d) if said
Brokers are the procuring cause of any other lease or sale entered into between
the Parties pertaining to the Premises and/or any adjacent property in which
Lessor has an interest, or (e) if Base Rent is increased, whether by agreement
or operation of an escalation clause herein, then as to any of said
transactions, Lessor shall pay said Brokers a fee in accordance with the
schedule of said Brokers in effect at the time of the execution of this Lease.

     15.4  Any buyer or transferee of Lessor's interest in this Lease, whether
such transfer is by agreement or by operation of law, shall be deemed to have
assumed Lessor's obligation under this Paragraph 15. Each Broker shall be a
third party beneficiary of the provisions of this Paragraph 15 to the extent of
its interest in any commission arising from this Lease and may enforce that
right directly against Lessor and its successors.

     15.5  Lessee and Lessor each represent and warrant to the other that it has
had no dealings with any person, firm, broker or finder (other than the Brokers,
if any named in Paragraph 1.10) in connection with the negotiation of this Lease
and/or the consummation of the transaction contemplated hereby, and that no
broker or other person, firm or entity other than said named Brokers is entitled
to any commission or finder's fee in connection with said transaction. Lessee
and Lessor do each hereby agree to indemnify, protect, defend and hold the other
harmless from and against liability for compensation or charges which may be
claimed by any such unnamed broker, finder or other similar party by reason of
any dealings or actions of

                                       25
<PAGE>
 
the indemnifying Party, including any costs, expenses, attorneys' fees
reasonably incurred with respect thereto.

     15.6  Lessor and Lessee hereby consent to and approve all agency
relationships, including any dual agencies, indicated in Paragraph 1.10.

16.  TENANCY STATEMENT.

     16.1  Each Party (as "Responding Party") shall within ten (10) days after
written notice from the other Party (the "Requesting Party") execute,
acknowledge and deliver to the Requesting Party a statement in writing in form
similar to the then most current "Tenancy Statement" form published by the
American Industrial Real Estate Association, plus such additional information,
confirmation and/or statements as may be reasonably requested by the Requesting
Party.

     16.2  If Lessor desires to finance, refinance, or sell the Premises, any
part thereof, or the building of which the Premises are a part, Lessee and all
Guarantors of Lessee's performance hereunder shall deliver to any potential
lender or purchaser designated by Lessor such financial statements of Lessee and
such Guarantors as may be reasonably required by such lender or purchaser,
including but not limited to Lessee's financial statements for the past three
(3) years. All such financial statements shall be received by Lessor and such
lender or purchaser in confidence and shall be used only for the purposes herein
set forth.

17.  LESSOR'S LIABILITY.  The term "Lessor" as used herein shall mean the owner
or owners at the time in question of the fee title to the Premises, or, if this
is a sublease, of the Lessee's interest in the prior lease.  In the event of a
transfer of Lessor's title or interest in the Premises or in this Lease, Lessor
shall deliver to the transferee or assignee (in cash or by credit) any unused
Security Deposit held by Lessor at the time of such transfer or assignment.
Except as provided in Paragraph 15, upon such transfer or assignment and
delivery of the Security Deposit, as aforesaid.  Subject to the foregoing, the
obligations and/or covenants in this Lease to be performed by the Lessor shall
be binding only upon the Lessor as hereinabove defined.

18.  SEVERABILITY.  The invalidity of any provision of this Lease, as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19.  INTEREST ON PAST-DUE OBLIGATIONS.  Any monetary payment due Lessor
hereunder, other than late charges, not received by Lessor within thirty (30)
days following the date on which it was due, shall bear interest from the
thirty-first (31st) day after it was due at the rate of 12% per annum, but not
exceeding the maximum rate allowed by law, in addition to the late charge
provided for in Paragraph 13.4.

20.  TIME.  Time of Essence.  Time is of the essence with respect to the
performance of all obligations to be performed or observed by the Parties under
this Lease.

21.  RENT DEFINED.  All monetary obligations of Lessee to Lessor under the terms
of this Lease are deemed to be rent.

22.  NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER.  This Lease contains all
agreements between the Parties with respect to any matter mentioned herein, and
no other prior or contemporaneous agreement or understanding shall be effective.
Lessor and Lessee each represents and warrants to the Brokers that it has made,
and is relying solely upon, its own investigation as to the nature, quality,
character and financial responsibility of the other Party to 

                                       26
<PAGE>
 
this Lease and as to the nature, quality and character of the Premises. Brokers
have no responsibility with respect thereto or with respect to any default or
breach hereof by either Party.

23.  NOTICES.

     23.1  All notices required or permitted by this Lease shall be in writing
and may be delivered (by hand or by messenger or courier service) or may be sent
by regular, certified or registered mail or U.S. Postal Service Express Mail,
with postage prepaid, or by facsimile transmission, and shall be deemed
sufficiently given if served in a manner specified in this Paragraph 23. The
addresses noted adjacent to a Party's signature on this Lease shall be that
Party's address for delivery or mailing of notice purposes. Either Party may by
written notice to the other specify a different address for notice purposes,
except that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for the purpose of mailing or delivering notices to
Lessee. A copy of all notices required or permitted to be given to Lessor
hereunder shall be concurrently transmitted to such party or parties at such
addresses as Lessor may from time to time hereafter designate by written notice
to Lessee.

     23.2  Any notice sent by registered or certified mail, return receipt
requested, shall be deemed given on the date of delivery shown on the receipt
card, or if no delivery date is shown, the postmark thereon.  If sent by regular
mail the notice shall be deemed given forty-eight (48) hours after the same is
addressed as required herein and mailed with postage prepaid.  Notices delivered
by United States Express Mail or overnight courier that guarantees next day
delivery shall be deemed given twenty-four (24) hours after delivery of the same
to the United States Post Service or courier.  If any notice is transmitted by
facsimile transmission or similar means, the same shall be deemed served or
delivered upon telephone confirmation of receipt of the transmission thereof,
provided a copy is also delivered via delivery or mail.  If notice is received
on a Sunday or legal holiday, it shall be deemed received on the next business
day.

24.  WAIVERS.  No waiver by Lessor of the Default or Breach of any term,
covenant, or condition hereof by Lessee, shall be deemed a waiver of any other
term, covenant or condition hereof, or of any subsequent Default or Breach by
Lessee of the same or of any other term, covenant or condition hereof. Lessor's
consent to, or approval of, any act shall not be deemed to render unnecessary
the obtaining of Lessor's consent to, or approval of, any subsequent similar act
by Lessee, or be construed as the basis of an estoppel to enforce the provision
or provisions of this Lease requiring such consent. Regardless of Lessor's
knowledge of a Default or Breach at the time of accepting rent, the acceptance
of rent by Lessor shall not be a waiver of any preceding Default or Breach by
Lessee of any provision hereof, other than the failure of Lessee to pay the
particular rent so accepted. Any payment given Lessor by Lessee may be accepted
by Lessor on account of moneys or damages due Lessor, notwithstanding any
qualifying statements or conditions made by Lessee in connection therewith,
which such statements and/or conditions shall be of no force or effect
whatsoever unless specifically agreed to in writing by Lessor at or before the
time of deposit of such payment.

25.  RECORDING.  Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a short form memorandum of this
Lease for recording purposes.  The Party requesting recordation shall be
responsible for payment of any fees or taxes applicable thereto.

                                       27
<PAGE>
 
26.  NO RIGHT TO HOLDOVER.  Lessee has no right to retain possession of the
Premises or any part thereof beyond the expiration or earlier termination of
this Lease.

27.  CUMULATIVE REMEDIES.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.  COVENANTS AND CONDITIONS.  All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

29.  BINDING EFFECT; CHOICE OF LAW.  This Lease shall be binding upon the
parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located.  Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

30.  SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

     30.1  SUBORDINATION.  This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust or other
hypothecation or security device (collectively, "SECURITY DEVICE"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default and
allow such Lender thirty (30) days following receipt of such notice for the cure
of said default before invoking any remedies Lessee may have by reasons thereof.
If any Lender shall elect to have this Lease and/or any Option granted hereby
superior to the lien of its Security Device and shall give written notice
thereof to Lessee, this Lease and such Options shall be deemed prior to such
Security Device, notwithstanding the relative dates of the documentation or
recordation thereof.

     30.2  ATTORNMENT.  Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device.

     30.3  NON-DISTURBANCE.  With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving assurance (a "NON-DISTURBANCE AGREEMENT") from the
Lender that Lessee's possession and this Lease, including any options to extend
the term hereof, will not be disturbed so long as Lessee is not in Breach hereof
and attorns to the record owner of the Premises.

     30.4  SELF-EXECUTING.  The agreements contained in this Paragraph 30 shall
be effective without the execution of any further documents; provided, however,
that, upon written request from Lessor or a Lender in connection with a sale,
financing or refinancing of the Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31.  ATTORNEY'S FEES.  If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) or Broker in any such proceeding, action, or appeal thereon,
shall be entitled to reasonable attorney's fees.  Such fees may be awarded in
the same suit or recovered in a separate suit, whether or not such action or
proceeding is pursued to decision or judgment.  The term, "PREVAILING PARTY"
shall 

                                       28
<PAGE>
 
include, without limitation, a Party or Broker who substantially obtains or
defeats the relief sought, as the case may be, whether by compromise,
settlement, judgment, or the abandonment by the other Party or Broker of its
claim or defense. The attorney's fee award shall not be computed in accordance
with any court fee schedule, but shall be such as to fully reimburse all
attorney's fees reasonably incurred. Lessor shall be entitled to attorney's
fees, costs and expenses incurred in the preparation and service of notices of
Default and consultations in connection therewith, whether or not a legal action
is subsequently commenced in connection with such Default or resulting Breach.

32.  LESSOR'S ACCESS; SHOWING PREMISES; REPAIRS.  Lessor and Lessor's agents
shall have the right to enter the Premises at any time, in the case of an
emergency, and otherwise at reasonable times for the purpose of showing the same
to prospective purchasers, lenders, or lessees, and making such alterations,
repairs, improvements or additions to the Premises or to the building of which
they are a part, as Lessor may reasonably deem necessary.  Lessor may at any
time place on or about the Premises or building any ordinary "For Sale" signs
and Lessor may at any time during the last one hundred twenty (120) days of the
term hereof place on or about the Premises any ordinary "For Lease" signs.  All
such activities of Lessor shall be without abatement of rent or liability to
Lessee.

33.  AUCTIONS.  Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises without first having
obtained Lessor's prior written consent.  Notwithstanding anything to the
contrary in this Lease, Lessor shall not be obligated to exercise any standard
of reasonableness in determining whether to grant such consent.

34.  SIGNS.  Lessee shall not place any sign upon the Premises, except that
Lessee may, with Lessor's prior written consent, install (but not on the roof)
such signs as are reasonably required to advertise Lessee's own business.  The
installation of any sign on the Premises by or for Lessee shall be subject to
the provisions of Paragraph 7 (Maintenance, Repairs, Utility Installations,
Trade Fixtures and Alterations).  Unless otherwise expressly agreed herein,
Lessor reserves all rights to the use of the roof and the right to install, and
all revenues from the installation of, such advertising signs on the Premises,
including the roof, as do not unreasonably interfere with the conduct of
Lessee's business.

35.  TERMINATION; MERGER.  Unless specifically stated otherwise in writing by
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual
termination or cancellation hereof, or a termination hereof by Lessor for Breach
by Lessee, shall automatically terminate any sublease or lesser estate in the
Premises; provided, however, Lessor shall, in the event of any such surrender,
termination or cancellation, have the option to continue any one or all of any
existing subtenancies.  Lessors' failure within ten (10) days following any such
event to make a written election to the contrary by written notice to the holder
of any such lesser interest, shall constitute Lessor's election to have such
event constitute the termination of such interest.

36.  CONSENTS.

     (a)  Except for Paragraph 33 hereof (Auctions) or as otherwise provided
herein, wherever in this Lease the consent of a Party is required to an act by
or for the other Party, such consent shall not be unreasonably withheld or
delayed.  Lessor's actual reasonable costs and expenses (including but not
limited to architects', attorneys', engineers' or other consultants' fees)
incurred in the consideration of, or response to, a request by Lessee for any
Lessor consent 

                                       29
<PAGE>
 
pertaining to this Lease or the Premises, including but not limited to consents
to an assignment, a subletting or the presence or use of a Hazardous Substance,
practice or storage tank, shall be paid by Lessee to Lessor upon receipt of an
invoice and supporting documentation therefor. Subject to Paragraph 12.2(e)
(applicable to assignment or subletting), Lessor may, as a condition to
considering any such request by Lessee, require that Lessee deposit with Lessor
an amount of money (in addition to the Security Deposit held under Paragraph 5)
reasonably calculated by Lessor to represent the cost Lessor will incur in
considering and responding to Lessee's request. Except as otherwise provided,
any unused portion of said deposit shall be refunded to Lessee without interest.
Lessor's consent to any act, assignment of this Lease or subletting of the
Premises by Lessee shall not constitute an acknowledgment that no Default or
Breach by Lessee of this Lease exists, nor shall such consent be deemed a waiver
of any then existing Default or Breach, except as may be otherwise specifically
stated in writing by Lessor at the time of such consent.

     (b)   All conditions to Lessor's consent authorized by this Lease are
acknowledged by Lessee as being reasonable.  The failure to specify herein any
particular condition to Lessor's consent shall not preclude the imposition by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular matter for which consent is being
given.

37.  GUARANTOR.

     37.1  If there are to be any Guarantors of this Lease per Paragraph 1.11,
the form of the guaranty to be executed by each such Guarantor shall be in the
form most recently published by the American Industrial Real Estate Association,
and each said Guarantor shall have the same obligations as Lessee under this
Lease, including but not limited to the obligation to provide the Tenancy
Statement and information called for by Paragraph 16.

     37.2  It shall constitute a Default of the Lessee under this Lease if any
such Guarantor fails or refuses, upon reasonable request by Lessor to give: (a)
evidence of the due execution of the guaranty called for by this Lease,
including the authority of the Guarantor (and of the party signing on
Guarantor's behalf) to obligate such Guarantor on said guaranty, and including
in the case of a corporate Guarantor, a certified copy of a resolution of its
board of directors authorizing the making of such guaranty, together with a
certificate of incumbency showing the signature of the persons authorized to
sign on its behalf, (b) current financial statements of Guarantor as may from
time to time be requested by Lessor, (c) a Tenancy Statement, or (d) written
confirmation that the guaranty is still in effect.

38.  QUIET POSSESSION.  Upon payment by Lessee of the rent for the Premises and
the observance and performance of all of the covenants, conditions and
provisions on Lessee's part to be observed and performed under this Lease,
Lessee shall have quiet possession of the Premises for the entire term hereof
subject to all of the provisions of this Lease.

39.  OPTIONS.
     
     39.1  DEFINITION.  As used in this Paragraph 39 the word "Option" has the
following meaning: (a) the right to extend the term of this Lease or to renew
this Lease or to extend or renew any lease that Lessee has on other property of
Lessor; (b) the right of first refusal to lease the Premises or the right of
first offer to lease the Premises or the right of first refusal to lease other
property of Lessor or the right of first offer to lease other property of
Lessor; (c) the right to

                                       30
<PAGE>
 
purchase the Premises, or the right of first refusal to purchase the Premises,
or the right of first offer to purchase the Premises, or the right to purchase
other property of Lessor, or the right of first refusal to purchase other
property of Lessor, or the right of first offer to purchase other property of
Lessor.

     39.2  OPTIONS PERSONAL TO ORIGINAL LESSEE.  Each Option granted to Lessee
in this Lease is personal to the original Lessee named in Paragraph 1.1 hereof,
and cannot be voluntarily or involuntarily assigned or exercised by any person
or entity other than said original Lessee while the original Lessee is in full
and actual possession of the Premises and without the intention of thereafter
assigning or subletting. The Options, if any, herein granted to Lessee are not
assignable, either as a part of an assignment of this Lease or separately or
apart therefrom, and no Option may be separated from this Lease in any manner,
by reservation or otherwise.

     39.3  MULTIPLE OPTIONS.  In the event that Lessee has any Multiple Options
to extend or renew this Lease, a later Option cannot be exercised unless the
prior Options to extend or renew this Lease have been validly exercised.

     39.4  EFFECT OF DEFAULT ON OPTIONS.

     (a)   Lessee shall have no right to exercise an Option, notwithstanding
any provision in the grant of Option to the contrary:  (i) during the period
commencing with the giving of any notice of Default under Paragraph 13.1 and
continuing until the noticed Default is cured, or (ii) during the period of time
any monetary obligation due Lessor from Lessee is unpaid (without regard to
whether notice thereof is given Lessee), or (iii) during the time Lessee is in
breach of this Lease, or (iv) in the event that Lessor has given to Lessee three
(3) or more notices of Default under Paragraph 13.1, whether or not the Defaults
are cured, during the twelve (12) month period immediately preceding the
exercise of the Option.

     (b)   The period of time within which an Option may be exercised shall not
be extended or enlarged by reason of Lessee's inability to exercise an Option
because of the provisions of Paragraph 39.4(a).

     (c)   All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessor gives to
Lessee three (3) or more notices of Default under Paragraph 13.1 during any
twelve (12) month period, whether or not the Defaults are cured, or (iii) if
Lessee commits a Breach of this Lease.

40.  MULTIPLE BUILDINGS.  If the Premises are part of a group of buildings
controlled by Lessor, Lessee agrees that it will abide by, keep and observe all
reasonable rules and regulations which Lessor may make from time to time for the
management, safety, care, and cleanliness of the grounds, the parking and
unloading of vehicles and the preservation of good order, as well as for the
convenience of other occupants or tenants of such other buildings and their
invitees, and that Lessee will pay its fair share of common expenses incurred in
connection therewith.

41.  SECURITY MEASURES.  Lessee hereby acknowledges that the rental payable to
Lessor hereunder does not include the cost of guard service or other security
measures, and that Lessor shall have no obligation whatsoever to provide same.
Lessee assumes all responsibility for the 

                                       31
<PAGE>
 
protection of the Premises, Lessee, its agents and invitees and their property
from the acts of third parties.

42.  RESERVATIONS.  Lessor reserves to itself the right, from time to time, to
grant, without the consent or joinder of Lessee, such easements, rights and
dedications that Lessor deems necessary, and to cause the recordation of parcel
maps and restrictions, so long as such easements, rights, dedications, maps and
restrictions do not unreasonably interfere with the use of the Premises by
Lessee.  Lessee agrees to sign any documents reasonably requested by Lessor to
effectuate any such easement rights, dedication, map or restrictions.

43.  PERFORMANCE UNDER PROTEST.  If at any time a dispute shall arise as to any
amount or sum of money to be paid by one Party to the other under the provisions
hereof, the Party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment and there shall survive the right on the part of
said Party to institute suit or recovery of such sum.  If it shall be adjudged
that there was no legal obligation on the part of said Party to pay such sum or
any part thereof, said Party shall be entitled to recover such sum or so much
thereof as it was not legally required to pay under the provisions of this
Lease.

44.  AUTHORITY.  If either Party hereto is a corporation, trust, or general or
limited partnership, each individual executing this Lease on behalf of such
entity represents and warrants that he or she is duly authorized to execute and
deliver this Lease on its behalf.  If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after request by Lessor,
deliver to Lessor evidence satisfactory to Lessor of such authority.

45.  CONFLICT.  Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions shall be controlled by the typewritten
or handwritten provisions.

46.  OFFER.  Preparation of this Lease by Lessor or Lessor's agent and
submission of same to Lessee shall not be deemed an offer to lease to Lessee.
This Lease is not intended to be binding until executed by all Parties hereto.

47.  AMENDMENTS.  This Lease may be modified only in writing, signed by the
parties in interest at the time of the modification.  The parties shall amend
this Lease from time to time to reflect any adjustments that are made to the
Base Rent or other rent payable under this Lease.  As long as they do not
materially change Lessee's obligations hereunder, Lessee agrees to make such
reasonable non-monetary modifications to this Lease as may be reasonably
required by an institutional, insurance company, or pension plan Lender in
connection with the obtaining of normal financing or refinancing of the property
of which the Premises are a part.

48.  MULTIPLE PARTIES.  Except as otherwise expressly provided herein, if more
than one person or entity is named herein as either Lessor or Lessee, the
obligations of such Multiple Parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor or Lessee.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND
PROVISION CONTAINED HEREIN, AND BY THE EXECUTION OF THIS LEASE SHOW THEIR
INFORMED AND VOLUNTARY CONSENT THERETO.  THE PARTIES HEREBY AGREE THAT, AT THE
TIME THIS LEASE IS EXECUTED, THE TERMS OF THIS LEASE ARE COMMERCIALLY REASONABLE

          BROKER(S) OR THEIR AGENTS OR EMPLOYEES AS TO THE LEGAL
          SUFFICIENCY, LEGAL EFFECT, OR TAX CONSEQUENCES OF THIS LEASE OR
          THE TRANSACTION TO WHICH IT RELATES; THE PARTIES SHALL RELY SOLELY
          UPON THE ADVICE OF THEIR OWN COUNSEL AS TO THE LEGAL AND TAX

Property to Tenant and Tenant leases the Property from Landlord for the Lease
Term. The Lease Term is for the period stated in Section 1.05 above and shall
begin and end on the dates specified in Section 10.05 above, unless the
beginning or end of the Lease Term is changed under any provision of this Lease.
The "Commencement Date" shall be the date specified in Section 1.05 above for
the beginning of the Lease Term, unless advanced or delayed under any provision
of this Lease.

         Section 2.02. DELAY IN COMMENCEMENT. Landlord shall not be liable to
Tenant if Landlord does not deliver possession of the Property to Tenant on the
Commencement Date. Landlord's non-delivery of the Property to Tenant on that
date shall not affect this Lease or the obligations of Tenant under this Lease
except that the Commencement Date shall be delayed until Landlord delivers
possession of the Property to Tenant and the Lease Term shall be extended for a
period equal to the delay in delivery of possession of the Property to Tenant,
plus the number of days necessary to end the Lease Term on the last day of a
month. If Landlord does not deliver possession of the Property to Tenant within

         Section 2.03. HOLDING OVER. Tenant shall vacate the Property upon the
expiration or earlier termination of this Lease. Tenant shall reimburse Landlord
for and indemnify Landlord against all damages which Landlord incurs from
Tenant's delay in vacating the Property. If Tenant does not vacate the Property
upon the expiration or earlier termination of the Lease and Landlord thereafter
accepts rent from Tenant, Tenant's occupancy of the Property shall be a
"month-to-month" tenancy, subject to all of the terms of this Lease applicable
to a month-to-month tenancy, except that the Base Rent then in effect shall be
increased by twenty-five percent (25%).

ARTICLE THREE: BASE RENT

         Section 3.01. TIME AND MANNER OF PAYMENT. Upon execution of this Lease,
Tenant shall pay Landlord the Base Rent in the amount stated in Paragraph

as Landlord may designate in writing.

Landlord a cash Security Deposit in the amount set forth in Section 1.10 above.

other charges due from Tenant or to cure any other defaults of Tenant. If
Landlord uses any part of the Security Deposit, Tenant shall restore the
Security Deposit to its full amount within ten (10) days after Landlord's
written request. Tenant's failure to do so shall be a material default under
this Lease. No interest shall be paid on the Security Deposit. Landlord shall
not be required to keep the Security Deposit separate from its other accounts
and no trust relationship is created with respect to the Security Deposit.

         Section 3.04  TERMINATION; ADVANCE PAYMENTS. Upon termination of this
Lease under Article Seven (Damage or Destruction), Article Eight (Condemnation)
or any other termination not resulting from Tenant's default, and after Tenant
has vacated the Property in the manner required by this Lease, Landlord shall
refund or credit to Tenant (or Tenant's successor) the unused portion of the
Security Deposit, any advance rent or other advance payments made by Tenant to
Landlord, and any amounts paid for real property taxes and other reserves which
apply to any time periods after termination of the Lease.

ARTICLE FOUR:  OTHER CHARGES PAYABLE BY TENANT

         Section 4.01. ADDITIONAL RENT. All charges payable by Tenant other than
Base Rent are called "Additional Rent." Unless this Lease provides otherwise,
Tenant shall pay all Additional Rent then due with the next monthly installment
of Base Rent. The Term "rent" shall mean Base Rent and Additional Rent.

         Section 4.02. PROPERTY TAXES.

                                       3
<PAGE>
 
         (a)   REAL PROPERTY TAXES. Tenant shall pay all real property taxes on
the Property (including any fees, taxes or assessments against, or as a result
of, any tenant improvements installed on the Property by or for the benefit of
Tenant) during the Lease Term. Subject to Paragraph 4.02(c) and Section 4.08
below, such payment shall be made at least ten (10) days prior to the
delinquency date of the taxes. Within such ten (10) day period, Tenant shall
furnish Landlord with satisfactory evidence that the real property taxes have
been paid. Landlord shall reimburse Tenant for any real property taxes paid by
Tenant covering any period of time prior to or after the Lease Term. If Tenant
fails to pay the real property taxes when due, Landlord may pay the taxes and
Tenant shall reimburse Landlord for the amount of such tax payment as Additional
Rent.

         (b)   DEFINITION OF "REAL PROPERTY TAX." "Real property tax" means: (i)
any fee, license fee, license tax, business license fee, commercial rental tax,
levy, charge, assessment, penalty or tax imposed by any taxing authority against
the Property, (ii) any tax on the Landlord's right to receive, or the receipt
of, rent or income from the Property or against the Landlord's business of
leasing the Property; (iii) any tax or charge of fire protection, streets,
sidewalks, road maintenance, refuse or other services provided to the Property
by any governmental agency; (iv) any tax imposed upon this transaction or based
upon a re-assessment of the Property due to a change of ownership, as defined by
applicable law, or other transfer of all or part of Landlord's interest in the
Property; and (v) any charge or fee replacing any tax previously included within
the definition of real property tax. "Real property tax" does not, however,
include Landlord's federal or state income, franchise, inheritance or estate
taxes.

         (c)   JOINT ASSESSMENT. If the Property is not separately assessed,
Landlord shall reasonably determine Tenant's share of the real property tax
payable by Tenant under Paragraph 4.02(a) from the assessor's worksheets or
other reasonably available information. Tenant shall pay such share to Landlord
within fifteen (15) days after receipt of Landlord's written statement.

         (d)   PERSONAL PROPERTY TAXES.

               (i)   Tenant shall pay all taxes charged against trade fixtures,
furnishings, equipment or any other personal property belonging to Tenant.
Tenant shall try to have personal property taxed separately from the Property.

               (ii)  If any of Tenant's personal property is taxed with the
Property, Tenant shall pay Landlord the taxes for the personal property within
fifteen (15) days after Tenant receives a written statement from Landlord for
such personal property taxes.

         Section 4.03. UTILITIES. Tenant shall pay, directly to the appropriate
supplier, the cost of all natural gas, heat, light, power, sewer service,
telephone, water, refuse disposal and other utilities and services supplied to
the Property. However, if any services or utilities are jointly metered with
other property, Landlord shall make a reasonable determination of Tenant's
proportionate share of the cost of such utilities and services and Tenant shall
pay such share to Landlord within fifteen (15) days after receipt of Landlord's
written statement.

         Section 4.04. INSURANCE POLICIES.

                                       4
<PAGE>
 
         (a)   LIABILITY INSURANCE. During the Lease Term, Tenant shall maintain
a policy of commercial general liability insurance (sometimes known as broad
form comprehensive general liability insurance) insuring Tenant against
liability for bodily injury, property damage (including loss of use of property)
and personal injury arising out of the operation, use or occupancy of the
Property. Tenant shall name Landlord as an additional insured under such policy.
The initial amount of such insurance shall be One Million Dollars ($1,000,000)
per occurrence and shall be subject to periodic increase based upon inflation,
increased liability awards, recommendation of Landlord's professional insurance
advisers and other relevant factors. The liability insurance obtained by Tenant
under this Paragraph 4.04(a) shall (i) be primarily and non-contributing; (ii)
contain cross-liability endorsements; and (iii) insure Landlord against Tenant's
performance under Section 5.05, if the matters giving rise to the indemnity
under Section 5.05 result from the negligence of Tenant. The amount and coverage
of such insurance shall not limit Tenant's liability nor relieve Tenant of any
other obligation under this Lease. Landlord may also obtain comprehensive public
liability insurance in an amount and with coverage determined by Landlord
insuring Landlord against liability arising out of ownership, operation, use or
occupancy of the Property. The policy obtained by Landlord shall not be
contributory and shall not provide primary insurance.

         (b)   PROPERTY AND RENTAL INCOME INSURANCE. During the Lease Term,
Landlord shall maintain policies of insurance covering loss of or damage to the
Property in the full amount of its replacement value. Such policy shall contain
an Inflation Guard Endorsement and shall provide protection against all perils
included within the classification of fire, extended coverage, vandalism,
malicious mischief, special extended perils (all risk), sprinkler leakage and
any other perils which Landlord deems reasonably necessary. Landlord shall have
the right to obtain flood and earthquake insurance if required by any lender
holding a security interest in the Property. Landlord shall not obtain insurance
for Tenant's fixtures or equipment or building improvements installed by Tenant
on the Property. During the Lease Term, Landlord shall also maintain a rental
income insurance policy, with loss payable to Landlord, in an amount equal to
one year's Base Rent, plus estimated real property taxes and insurance premiums.
Tenant shall be liable for the payment of any deductible amount under Landlord's
or Tenant's insurance policies maintained pursuant to this Section 4.04, in an
amount not to exceed Ten Thousand Dollars ($10,000). Tenant shall not do or
permit anything to be done which invalidates any such insurance policies.

         (c)   PAYMENT OF PREMIUMS. Subject to Section 4.08, Tenant shall pay
all premiums for the insurance policies described in Paragraphs 4.04(a) and (b)
(whether obtained by Landlord or Tenant) within fifteen (15) days after Tenant's
receipt of a copy of the premium statement or other evidence of the amount due,
except Landlord shall pay all premiums for non-primary comprehensive public
liability insurance which Landlord elects to obtain as provided in Paragraph
4.04(a). For insurance policies maintained by Landlord which cover improvements
on the entire Project, Tenant shall pay Tenant's prorated share of the premiums,
in accordance with the formula in Paragraph 4.05(e) for determining Tenant's
share of Common Areas costs. If insurance policies maintained by Landlord cover
improvements on real property other than the

                                       5
<PAGE>
 
Project, landlord shall deliver to Tenant a statement of the premium applicable
to the Property showing in reasonable detail how Tenant's share of the premium
was computed. If the Lease Term expires before the expiration of an insurance
policy maintained by Landlord, Tenant shall be liable for Tenant's prorated
share of the insurance premiums. Before the Commencement Date, Tenant shall
deliver to Landlord a copy of any policy of insurance which Tenant is required
to maintain under this Section 4.04. At least thirty (30) days prior to the
expiration of any such policy, Tenant shall deliver to Landlord a renewal of
such policy. As an alternative to providing a policy of insurance, Tenant shall
have the right to provide Landlord a certificate of insurance, executed by an
authorized officer of the insurance company, showing that the insurance which
Tenant is required to maintain under this Section 4.04 is in full force and
effect and containing such other information which Landlord reasonably requires.

         (d)   GENERAL INSURANCE PROVISIONS.

               (i)   Any insurance which Tenant is required to maintain under
this Lease shall include a provision which requires the insurance carrier to
give Landlord not less than thirty(30) days' written notice prior to any
cancellation or modification of such coverage.

               (ii)  If Tenant fails to deliver any policy, certificate or
renewal to Landlord required under this Lease within the prescribed time period
or if any such policy is cancelled or modified during the Lease Term without
Landlord's consent, Landlord may obtain such insurance, in which case Tenant
shall reimburse Landlord for the cost of such insurance within fifteen (15) days
after receipt of a statement that indicates the cost of such insurance.

               (iii) Tenant shall maintain all insurance required under this
Lease with companies holding a "General Policy Rating" of A-12 or better, as set
forth in the most current issue of "Best Key Rating Guide". Landlord and Tenant
acknowledge the insurance markets are rapidly changing and that insurance in the
form and amounts described in this Section 4.04 may not be available in the
future. Tenant acknowledges that the insurance described in this Section 4.04 is
the primary benefit of Landlord. If at any time during the Lease Term, Tenant is
unable to maintain the insurance required under the Lease, Tenant shall
nevertheless maintain insurance coverage which is customary and commercially
reasonable in the insurance industry for Tenant's type of business, as that
coverage may change from time to time. Landlord makes no representation as to
the adequacy of such insurance to protect Landlord's or Tenant's interests.
Therefore, Tenant shall obtain any such additional property or liability
insurance which Tenant deems necessary to protect Landlord and Tenant.

               (iv)  Unless prohibited under any applicable insurance polices
maintained, Landlord and Tenant each hereby waive any and all rights of recovery
against the other, or against the officers, employees, agents or representatives
of the other, for loss of or damage to its property or the property of others
under its control, if such loss or damage is covered by any insurance policy in
force (whether or not described in this Lease) at the time of such loss or
damage. Upon obtaining the required policies of insurance, Landlord and Tenant
shall give notice to the insurance carriers of this mutual waiver of
subrogation.

         Section 4.05.  COMMON AREAS; USE, MAINTENANCE AND COSTS.

                                       6
<PAGE>
 
         (a)   COMMON AREAS. As used in this Lease, "Common Areas" shall mean
all areas within the Project which are available for the common use of tenants
of the Project and which are not leased or held for the exclusive use of Tenant
or other tenants, including, but not limited to, parking areas, driveways,
sidewalks, loading areas, access roads, corridors, landscaping and planted
areas. Landlord, from time to time, may change the size, location, nature and
use of any of the Common Areas, convert Common Areas into leaseable areas,
construct additional parking facilities (including parking structures) in the
Common Areas, and increase or decrease Common Area land and/or facilities.
Tenant acknowledges that such activities may result in inconvenience to Tenant.
Such activities and changes are permitted if they do not materially affect
Tenant's use of the Property.

         (b)   USE OF COMMON AREAS. Tenant shall have the nonexclusive right (in
common with other tenants and all others to whom Landlord has granted or may
grant such rights) to use the Common Areas for the purposes intended, subject to
such reasonable rules and regulations as Landlord may establish from time to
time. Tenant shall abide by such rules and regulations and shall use its best
effort to cause others who use the Common Areas with Tenant's express or implied
permission to abide by Landlord's rule and regulations. At any time, Landlord
may close any Common Areas to perform any acts in the Common Areas as, in
Landlord's judgment, are desirable to improve the Project. Tenant shall not
interfere with the rights of Landlord, other tenants or any other person
entitled to use the Common Areas.

         (c)   SPECIFIC PROVISION RE: VEHICLE PARKING. Tenant shall be entitled
to use the number of vehicle parking spaces in the Project allocated to Tenant
in Section 1.11 of the Lease without paying any additional rent. Tenant's
parking shall not be reserved and shall be limited to vehicles no larger than
standard size automobiles or pickup utility vehicles. Tenant shall not cause
large trucks or other large vehicles to be parked within the Project or on the
adjacent public streets. Temporary parking of large delivery vehicles in the
Project may be permitted by the rules and regulations established by Landlord.
Vehicles shall be parked only in striped parking spaces and not in driveways,
loading areas or other locations not specifically designated for parking.
Handicapped spaces shall only be used by those legally permitted to use them. If
Tenant parks more vehicles in the parking area than the number set forth in
Section 1.11 of this Lease, such conduct shall be a material breach of this
Lease. In addition to Landlord's other remedies under the Lease, Tenant shall
pay a daily charge determined by Landlord for each such additional vehicle.

         (d)   MAINTENANCE OF COMMON AREAS. Landlord shall maintain the Common
Areas in good order, condition and repair and shall operate the Project, in
Landlord's sole discretion, as a first-class industrial/commercial real property
development. Tenant shall pay Tenant's pro rata share (as determined below) of
all costs incurred by Landlord for the operation and maintenance of the Common
Areas. Common Areas costs include, but are not limited to, costs and expenses
for the following: gardening and landscaping; utilities, water and sewage
charges; maintenance of signs (other than tenants' signs); premiums for
liability, property damage, fire and other types of casualty insurance on the
Common Areas and worker's compensation insurance; all property taxes and
assessments levied on or attributable to the Common Areas and all Common Area

                                       7
<PAGE>
 
improvements; all personal property taxes levied on or attributable to personal
property used in connection with the Common Areas; straight-line depreciation on
personal property owned by Landlord which is consumed in the operation or
maintenance of the Common Areas; rental or lease payments paid by Landlord for
rented or leased personal property used in the operation or maintenance of the
Common Areas; fees for required licenses and permits; repairing, resurfacing,
repaving, maintaining, painting, lighting, cleaning, refuse removal, security
and similar items,; reserves for roof replacement and exterior painting and
other appropriate reserves; and a reasonable allowance to Landlord for
Landlord's supervision of the Common Areas (not to exceed five percent (5%) of
the gross rents of the Project for the calendar year). Landlord may cause any or
all of such services to be provided by third parties and the cost of such
services shall be included in Common Area costs. Common Area costs shall not
include depreciation of real property which forms part of the Common Areas.

         (e)   TENANT'S SHARE AND PAYMENT. Tenant shall pay Tenant's annual pro
rata share of all Common Area costs (prorate for any fractional month) upon
written notice from Landlord that such costs are due and payable, and in any
event prior to delinquency. Tenant's pro rata share shall be calculated by
dividing the square foot area of the property, as set forth in Section 1.04 of
the Lease, by the aggregate square foot area of the Project which is leased or
held for lease by tenants, as on the date on which the computation is made.
Tenant's initial pro rata share is set out in Paragraph 1.12(b). Any changes in
the Common Area costs and/or the aggregate area of the Project leased or held
for lease during the Lease Term shall be effective on the first day of the month
after such change occurs. Landlord may, at Landlord's election, estimate in
advance and charge to Tenant as Common Area costs, all real property taxes for
which Tenant is liable under Section 4.02 of the Lease, all insurance premiums
for which Tenant is liable under Section 4.04 of the Lease, all maintenance and
repair costs for which Tenant is liable under Section 6.04 of the Lease, and all
other Common Area costs payable by Tenant hereunder. At Landlord's election,
such statements of estimated Common Area costs shall be delivered monthly,
quarterly or at any other periodic intervals to be designated by Landlord.
Landlord may adjust such estimates at any time based upon Landlord's experience
and reasonable anticipation of costs. Such adjustments shall be effective as of
the next rent payment date after notice to Tenant. Within sixty (60) days after
the end of each calendar year of the Lease Term, Landlord shall deliver to
Tenant a statement prepared in accordance with generally accepted accounting
principles setting forth, in reasonable detail, the Common Area costs paid or
incurred by Landlord during the preceding calendar year and Tenant's pro rata
share. Upon receipt of such statement, there shall be an adjustment between
Landlord and Tenant, with payment to or credit given by Landlord (as the case
may be) so that the Landlord shall receive the entire amount of Tenant's share
of such costs and expenses for such period.

         Section 4.06. LATE CHARGES. Tenant's failure to pay rent promptly may
cause Landlord to incur unanticipated costs. The exact amount of such costs are
impractical or extremely difficult to ascertain. Such costs may include, but are
not limited to, processing and accounting charges and late charges which may be
imposed on Landlord by any ground lease, mortgage or trust deed encumbering the
Property. Therefore, if Landlord does not receive any rent payment 

                                       8
<PAGE>
 
within ten (10) days after it becomes due, Tenant shall pay Landlord a late
charge equal to ten percent (10%) of the overdue amount. The parties agree that
such late charges represents a fair and reasonable estimate of the costs
Landlord will incur by reason of such late payment.

         Section 4.07. INTEREST ON PAST DUE OBLIGATIONS. Any amount owed by
Tenant to Landlord which is not paid when due shall bear interest at the rate of
fifteen percent (15%) per annum from the due date of such amount. However,
interest shall not be payable on late charges to be paid by Tenant under this
Lease. The payment of interest on such amounts shall not excuse or cure any
default by Tenant under this Lease. If the interest rate specified in this Lease
is higher than the rate permitted by law, the interest rate is hereby decreased
to the maximum legal interest rate permitted by law.

         Section 4.08. IMPOUNDS FOR INSURANCE PREMIUMS AND REAL PROPERTY TAXES.
If requested by any ground lessor or lender to whom Landlord has granted a
security interest in the Property, or if Tenant is more than ten (10) days late
in the payment of rent more than once in any consecutive twelve (12) month
period, Tenant shall pay Landlord a sum equal to one-twelfth (1/12) of the
annual real property taxes and insurance premiums payable by Tenant under this
Lease, together with each payment of Base Rent. Landlord shall hold such
payments in a non-interest bearing impound account. If unknown, Landlord shall
reasonably estimate the amount of real property taxes and insurance premiums
when due. Tenant shall pay any deficiency of funds in the impound account to
Landlord upon written request. If Tenant defaults under this Lease, Landlord may
apply any funds in the impound account to any obligation then due under this
Lease.

pesticides, ammonia, compounds and other chemical products, asbestos, PCBs and
similar compounds, and including any different products and 

                                       9
<PAGE>
 
materials which are subsequently found to have adverse effects on the
environment or the health and safety of persons. Tenant shall not cause or
permit any Hazardous Material to be generated, produced, brought upon, used,
stored, treated or disposed of in or about the Property by Tenant, its agents,
employees, contractors, sublessees or invitees without the written consent of
Landlord. Landlord shall be entitled to take into account such other factors or
facts as Landlord may reasonably determine to be relevant in determining whether
to grant or withhold consent to Tenant's proposed activity with respect to
Hazardous Material. In no event, however, shall Landlord be required to consent
to the installation or use of any storage tanks on the Property.

the Property without Landlord's prior written consent. Tenant shall not conduct
or permit any auctions or sheriff's sales at the Property.

         Section 5.05. INDEMNITY. Tenant shall indemnify Landlord against and
hold Landlord harmless from any and all costs, claims or liability arising from:
(a) Tenant's use of the Property; (b) the conduct of Tenant's business or
anything else done or permitted by Tenant to be done in or about the Property,
including any contamination of the Property or any other property resulting from
the presence or use of Hazardous Material caused or permitted by Tenant; (c) any
breach or default in the performance of Tenant's obligations under this Lease;
(d) any misrepresentation or breach of warranty by Tenant under the Lease; or
(e) other acts or omissions of Tenant. Tenant shall defend Landlord against any
such costs, claims or liability at Tenant's expense with counsel reasonably
acceptable to Landlord or, at Landlord's election, Tenant shall reimburse
Landlord for any legal fees or costs incurred by Landlord in connection with any
such claim. As a material part of the consideration to Landlord, Tenant assumes
all risk of damage to property or injury to persons in or about the Property
arising from any cause, and Tenant hereby waives all claims in respect thereof
against Landlord, except for any claim arising out of Landlord's gross
negligence or willful misconduct. As used in this Section, the term "Tenant"
shall include Tenant's employees, agents, contractors and invitees, if
applicable.

         Section 5.06. LANDLORD'S ACCESS. Landlord or its agents may enter the
Property at all reasonable times to show the Property to potential buyers,
investors or tenants or other parties; to do any other act or to inspect and
conduct tests in order to monitor Tenant's compliance with all applicable
environmental laws and all laws governing the presence and use of Hazardous
Material; or for any other purposes Landlord deems necessary. Landlord shall
give Tenant prior notice of such entry, except in the case of an emergency.
Landlord may place customary "For Sale" or "For Lease" signs on the Property.

         Section 5.07. QUIET POSSESSION. If Tenant pays the rent and complies
with all other terms of this Lease, Tenant may occupy and enjoy the Property for
the full Lease Term, subject to the provisions this Lease.

ARTICLE SIX:   CONDITION OF PROPERTY; MAINTENANCE, REPAIRS AND ALTERATIONS

         Section 6.01. EXISTING CONDITIONS. Tenant accepts the Property in its
condition as of the execution of the Lease, subject to all recorded matters,
laws, ordinances, and governmental 

                                       10
<PAGE>
 
regulations and orders. Except as provided herein, Tenant acknowledges that
neither Landlord nor any agent or Landlord has made any representation as to the
condition of the Property or the suitability of the Property for Tenant's
intended use. Tenant represents and warrants that Tenant has made its own
inspection of and inquiry regarding the condition of the Property and is not
relying on any representations of Landlord or any Broker with respect thereto.
If Landlord or Landlord's Broker has provided a Property Information Sheet or
other Disclosure Statement regarding the Property, a copy is attached as an
exhibit to the Lease.

         Section 6.02. EXEMPTION OF LANDLORD FROM LIABILITY. Landlord shall not
be liable for any damage or injury to the person, business (or any loss of
income therefrom), goods, wares, merchandise or other property of Tenant,
Tenant's employees, invitees, customers or any other person in or about the
Property, whether such damage or injury is caused by or results from: (a) fire,
steam, electricity, water, gas or rain; (b) the breakage, leakage, obstruction
or other defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures or any other cause; (c) conditions arising in
or about the Property or upon other portions of the Project from other sources
or places; or (d) any act or omission of any other tenant of the Project.
Landlord shall not be liable for any such damages or injury even though the
causes of or the means of repairing such damage or injury are not accessible to
Tenant. The provision of this Section 6.02 shall not, however, exempt Landlord
from liability for Landlord's gross negligence or willful misconduct.

         Section 6.03. LANDLORD'S OBLIGATIONS.

         (a)   Except as provided in Article Seven (Damage or Destruction) and
Article Eight (Condemnation), Landlord shall keep the following in good order,
condition and repair: the foundations, exterior walls and roof of the Property
(including painting the exterior surface of the exterior walls of the Property
not more often than once every five (5) years, if necessary) and all components
of electrical, mechanical, plumbing, heating and air conditioning systems and
facilities located in the Property which are concealed or used in common by
tenants of the Project. However, Landlord shall not be obligated to maintain or
repair windows, doors, plate glass or the interior surfaces of exterior walls.
Landlord shall make repairs under this Section 6.03 within a reasonable time
after receipt of written notice from Tenant of the need for such repairs.

         (b)   Tenant shall pay or reimburse Landlord for all costs Landlord
incurs under Paragraph 6.03(a) above as Common Area costs as provided for in
Section 4.05 of the Lease. Tenant waives the benefit of any statute in effect
now or in the future which might give Tenant the right to make repairs at
Landlord's expense or to terminate this Lease due to Landlord's failure to keep
the Property in good order, condition and repair.

         Section 6.04. TENANT'S OBLIGATIONS.

         (a)   Except as provided in Section 6.03, Article Seven (Damage or
Destruction) and Article Eight (Condemnation), Tenant shall keep all portions of

equipment) in good order, condition and repair (including interior repainting
and refinishing, as needed). If any portion of the Property or any 

                                       11
<PAGE>
 
system or equipment in the Property which Tenant is obligated to repair cannot
be fully repaired or restored, Tenant shall promptly replace such portion of the
Property or system or equipment in the Property, regardless of whether the
benefit of such replacement extends beyond the Lease Term; but if the benefit or
useful life of such replacement extends beyond the Lease Term (as such term may
be extended by exercise of any options), the useful life of such replacement
shall be prorated over the remaining portion of the Lease Term (as extended),
and Tenant shall be liable only for that portion of the cost which is applicable
to the Lease Term (as extended). Tenant shall maintain a preventative
maintenance contract providing for the regular inspection and maintenance of the
heating and air conditioning system by a licensed heating and air conditioning
contractor, unless Landlord maintains such equipment under Section 6.03 above.
If any part of the Property or the Project is damaged by any act or omission of
Tenant, Tenant shall pay Landlord the cost of repairing or replacing such
damaged property, whether or not Landlord would otherwise be obligated to pay
the cost of maintaining or repairing such property. It is the intention of
Landlord and Tenant that at all times Tenant shall maintain the portions of the
Property which Tenant is obligated to maintain in an attractive, first-class and
fully operative condition.

         (b)   Tenant shall fulfill all of Tenant's obligations under this
Section 6.04 at Tenant's sole expense. If Tenant fails to maintain, repair or
replace the Property as required by this Section 6.04, Landlord may, upon ten
(10) days' prior notice to Tenant (except that no notice shall be required in
the case of an emergency), enter the Property and perform such maintenance or
repair including replacement, as needed) on behalf of Tenant. In such case,
Tenant shall reimburse Landlord for all costs incurred in performing such
maintenance or repair immediately upon demand.

         Section 6.05.  ALTERATIONS, ADDITIONS AND IMPROVEMENTS.

         (a)   Tenant shall not make any alterations, additions or improvements
to the Property without Landlord's prior written consent, except for non-
structural alterations which do not exceed Ten Thousand Dollars ($10,000) in
cost cumulatively over the Lease Term and which are not visible from the outside
of any building of which the Property is part. Landlord may require Tenant to
provide demolition and/or lien and completion bonds in form and amount
satisfactory to Landlord. Tenant shall promptly remove any alterations,
additions, or improvements construed in violation of this Paragraph 6.05(a) upon
Landlord's written requests. All alterations, additions, and improvements shall
be done in a good and workmanlike manner, in conformity with all applicable laws
and regulations, and by a contractor approved by Landlord. Upon completion of
any such work, Tenant shall provide Landlord with "as built" plans, copies of
all construction contracts, and proof of payment for all labor and materials.

         (b)   Tenant shall pay when due all claims for labor and material
furnished to the Property. Tenant shall give the Landlord at least twenty (20)
days' prior written notice of the commencement of any work on the Property,
regardless of whether Landlord's consent to such work is required. Landlord may
elect to record and post notices of non-responsibility on the Property.

                                       12
<PAGE>
 
         Section 6.06. CONDITION UPON TERMINATION. Upon the termination of the
Lease, Tenant shall surrender the Property to Landlord, broom clean and in the
same condition as received except for ordinary wear and tear with Tenant was not
otherwise obligated to remedy under any provision of this Lease. However, Tenant
shall not be obligated to repair any damage which Landlord is required to repair
under Article Seven (Damage or Destruction). In addition, Landlord may require
Tenant to remove any alterations, additions or improvements (whether or not made
with Landlord's consent) prior to the expiration of the Lease and to restore the
Property to its prior condition, all at Tenant's expense. All alterations,
additions and improvements which Landlord has not required Tenant to remove
shall become Landlord's property and shall be surrendered to Landlord upon the
expiration or earlier termination of the Lease, except that Tenant may remove
any of Tenant's machinery or equipment which can be removed without material
damage to the property. Tenant shall repair, at Tenant's expense, any damage to
the Property caused by the removal of any such machinery or equipment. In no
event, however, shall Tenant remove any of the following materials or equipment
(which shall be deemed Landlord's property) without Landlord's prior written
consent; any power wiring or power panels; lighting or lighting fixtures; wall
covering; drapes, blinds or other window coverings; carpets or other floor
coverings; heaters, air conditioners or any other heating or air conditioning
equipment; fencing or security gates; or other similar building operating
equipment and decorations.

ARTICLE SEVEN:  DAMAGE OR DESTRUCTION

         Section 7.01  PARTIAL DAMAGE TO PROPERTY.

         (a)   Tenant shall notify Landlord ins writing immediately upon the
occurrence of any damage to the Property. If the Property is only partially
damaged (i.e., less than fifty percent (50%) of the Property is untenantable as
a result of such damage or less than fifty percent (50%) of Tenant's operations
are materially impaired) and if the proceeds received by Landlord from the
insurance policies described in Paragraph 4.04 (b) are sufficient to pay for the
necessary repairs, this Lease shall remain in effect and Landlord shall repair
the damage as soon as reasonably possible. Landlord may elect (but is not
required) to repair any damage to Tenant's fixtures, equipment, or improvements.

         (b)   If the insurance proceeds received by Landlord are not sufficient
to pay the entire cost of repair, or if the cause of the damage is not covered
by the insurance policies which Landlord maintains under Paragraph 4.04(b),
Landlord may elect either to (i) repair the damage as soon as reasonably
possible, in which case this Lease shall remain in full force and effect, or
(ii) terminate this Lease as of the date the damage occurred. Landlord shall
notify Tenant within thirty (30) days after receipt of notice of the occurrence
of the damage whether Landlord elects to repair the damage or terminate the
Lease. If Landlord elects to repair the damage, Tenant shall pay Landlord the
"deductible amount" (if any) under Landlord's insurance policies and, if the
damage was due to an act or omission of Tenant, or Tenant's employees, agents,
contractors or invitees, the difference between the actual cost of repair and
any insurance proceeds received by Landlord. If Landlord elects to terminate the
Lease, Tenant may elect to continue this Lease in full force and effect, in
which case Tenant shall repair any damage to the Property and any 

                                       13
<PAGE>
 
building in which the Property is located. Tenant shall pay the cost of such
repairs, except that upon satisfactory completion of such repairs, Landlord
shall deliver to Tenant any insurance proceeds received by Landlord for the
damage repaired by Tenant. Tenant shall give Landlord written notice of such
election within ten (10) days after receiving Landlord's termination notice.

         (c)   If the damage to the Property occurs during the last six (6)
months of the Lease Term and such damage will require more than thirty (30) days
to repair, either Landlord or Tenant may elect to terminate this Lease as of the
date the damage occurred, regardless of the sufficiency of any insurance
proceeds. The party electing to terminate this Lease shall give written
notification to the other party of such election within thirty (30) days after
Tenant's notice to Landlord of the occurrence of the damage.

         Section 7.02. SUBSTANTIAL OR TOTAL DESTRUCTION. If the Property is
substantially or totally destroyed by any cause whatsoever (i.e., the damage to
the Property is greater than partial damage as described in Section 7.01), and
regardless of whether Landlord receives any insurance proceeds, this Lease shall
terminate as of the date the destruction occurred. Notwithstanding the preceding
sentence, if the Property can be rebuilt within six (6) months after the date of
destruction, Landlord may elect to rebuild the Property at Landlord's own
expense, in which case this Lease shall remain in full force and effect.
Landlord shall notify Tenant of such election within thirty (30) days after
Tenant's notice of the occurrence of total or substantial destruction. If
Landlord so elects, Landlord shall rebuild the Property at Landlord's sole
expense, except that if the destruction was caused by an act or omission of
Tenant, Tenant shall pay Landlord the difference between the actual cost of
rebuilding and any insurance proceeds received by Landlord.

         Section 7.03. TEMPORARY REDUCTION OF RENT. If the Property is destroyed
or damaged and Landlord or Tenant repairs or restores the Property pursuant to
the provision of this Article Seven, any rent payable during the period of such
damage, repair and/or restoration shall be reduced according to the degree, if
any, to which Tenant's use of the Property is impaired. However, the reduction
shall not exceed the sum of one year's payment of Base Rent, insurance premiums
and real property taxes. Except for such possible reduction in Base Rent,
insurance premium and real property taxes, Tenant shall not be entitled to any
compensation, reduction, or reimbursement from Landlord as a result of any
damage, destruction, repair, or restoration of or to this Property.

         Section 7.04. WAIVER. Tenant waives the protection of any statute, code
or judicial decision which grants a tenant the right to terminate a lease in the
event of the substantial or total destruction of the leased property. Tenant
agrees that the provision of Section 7.02 above shall govern the rights and
obligations of Landlord and Tenant in the event of any substantial or total
destruction to the Property.

ARTICLE EIGHT:  CONDEMNATION

         If all or any portion of the Property is taken under the power of
eminent domain or sold under the threat of that power (all of which are called
"Condemnation"), this Lease shall terminate as to the part taken or sold on the
date the condemning authority takes title or 

                                       14
<PAGE>
 
possession, whichever occurs first. If more than twenty percent (20%) of the
floor area of the building in which the Property is located, or which is located
on the Property, is taken, either Landlord or Tenant may terminate this Lease as
of the date the condemning authority takes title or possession, by delivering
written notice to the other within ten (10) days after receipt of written notice
of such taking (or in the absence of such notice, within ten (10) days after the
condemning authority takes title or possession). If neither Landlord or Tenant
terminate this Lease this Lease shall remain in effect as to the portion of the
Property not taken, except that the Base Rent and Additional Rent shall be
reduced in proportion to the reduction in the floor area of the Property. Any
Condemnation award or payment shall be distributed in the following order: (a)
first, to any ground lessor, mortgagee or beneficiary under a deed of trust
encumbering the Property, the amount of its interest in the Property, (b)
second, to Tenant, only the amount of any award specifically designated for loss
or damage to Tenant's trade fixtures or removable personal property; and (c)
third, to Landlord, the remainder of such award, whether as compensation for
reduction in the value of the leasehold, the taking of the fee, or otherwise. If
this Lease is not terminated, Landlord shall repair any damage to the Property
caused by Condemnation except that Landlord shall not be obligated to repair any
damage for which Tenant has been reimbursed by the condemning authority. If the
severance damages received by Landlord are not sufficient to pay for such
repair, Landlord shall have the right to either terminate this Lease or make
such repair at Landlord's expense.

ARTICLE NINE:  ASSIGNMENT AND SUBLETTING

     Section 9.01.  LANDLORD'S CONSENT REQUIRED. No portion of the Property or
of Tenant's interest in this Lease may be acquired by any other person or
entity, whether by sale, assignment, mortgage, sublease, transfer, operation of
law, or act of Tenant, without Landlord's prior written consent, except as
provided in Section 9.02 below. Landlord has the right to grant or withhold its
consent as provided in Section 9.05 below. Any attempted transfer without
consent shall be void and shall constitute a non-curable breach of this Lease.
If Tenant is a partnership, any cumulative transfer of more than twenty percent
(20%) of the partnership interest shall require Landlord's consent. If Tenant is
a corporation, any change in the ownership of a controlling interest of the
voting stock of the corporation shall require Landlord's consent.

     Section 9.02.  TENANT AFFILIATE. Tenant may assign this Lease or sublease
the Property, without Landlord's consent, to any corporation which controls, is
controlled by or is under common control with Tenant, or to any corporation
resulting from the merger of or consolidation with Tenant ("Tenant's
Affiliate"). In such case, any Tenant's Affiliate shall assume in writing all of
Tenant's obligations under this Lease.

     Section 9.03.  NO RELEASE OF TENANT. No transfer permitted by this Article
Nine, whether with or without Landlord's consent, shall release Tenant or change
Tenant's primary liability to pay the rent and to perform all other obligations
of Tenant under this Lease. Landlord's acceptance of rent from any other person
is not a waiver of any provision of this Article Nine. Consent to one transfer
is not a consent to any subsequent transfer. If Tenant's transferee defaults
under this Lease, Landlord may proceed directly against Tenant without

                                       15
<PAGE>
 
pursuing remedies against the transferee. Landlord may consent to subsequent
assignments or modifications of this Lease by Tenant's transferee, without
notifying Tenant or obtaining its consent. Such action shall not relieve
Tenant's liability under this Lease.

     Section 9.04.  OFFER TO TERMINATE.  If Tenant desires to assign the Lease
or sublease the Property, Tenant shall have the right to offer, in writing, to
terminate the Lease as of a date specified in the offer. If Landlord elects in
writing to accept the offer to terminate within twenty (20) days after notice of
the offer, the Lease shall terminate as of the date specified and all the terms
and provisions of the Lease governing termination shall apply. If Landlord does
not so elect, the Lease shall continue in effect until otherwise terminated and
the provisions of Section 9.05 with respect to any proposed transfer shall
continue to apply.

     Section 9.05.  LANDLORD'S CONSENT.

     (a)  Tenant's request for consent to any transfer described in Section 9.01
shall set forth in writing the details of the proposed transfer, including the
name, business and financial condition of the prospective transferee, financial
details of the proposed transfer (e.g., the term of and the rent and security
deposit payable under any proposed assignment or sublease), and any other
information Landlord deems relevant. Landlord shall have the right to withhold
consent, if reasonable, or to grant consent based on the following factors: (i)
the business of the proposed assignment or subtenant and the proposed use of the
Property; (ii) the net worth and financial reputation of the proposed assignee
or subtenant; (iii) Tenant's compliance with all of its obligations under the
Lease; and (iv) such other factors as Landlord may reasonably deem relevant. If
Landlord objects to a proposed assignment solely because of the net worth and/or
financial reputation of the proposed assignee, Tenant may nonetheless sublease
(but not assign), all or a portion of the Property to the proposed transferee,
but only on the other terms of the proposed transfer.

     (b)  If Tenant assigns or subleases, the following shall apply:

          (i)  Tenant shall pay to Landlord as Additional Rent under the Lease
the Landlord's Share (stated in Section 1.13) of the Profit (defined below) on
such transaction as and when received by Tenant, unless Landlord gives written
notice to Tenant and the assignee or subtenant that Landlord's Share shall be
paid by the assignee or subtenant to Landlord directly. The "Profit" means (A)
all amounts paid to Tenant for such assignment or sublease, including "key"
money, monthly rent in excess of the monthly rent payable under the Lease, and
all fees and other consideration paid for the assignment or sublease, including
fees under any collateral agreements, less (B) costs and expenses directly
incurred by Tenant in connection with the execution and performance of such
assignment or sublease for real estate broker's commissions and costs of
renovation or construction of tenant improvements required under such assignment
or sublease. Tenant is entitled to recover such costs and expenses before Tenant
is obligated to pay the Landlord's share to Landlord. The Profit in the case of
a sublease of less than all the Property is the rent allocable to the subleased
space as a percentage on a square footage basis.

          (ii) Tenant shall provide Landlord a written statement certifying all
amounts to be paid from any assignment or sublease of the Property within thirty
(30) days after the transaction

                                       16
<PAGE>
 
documentation is signed, and Landlord may inspect Tenant's books and records to
verify the accuracy of such statement. On written request, Tenant shall promptly
furnish to Landlord copies of all the transaction documentation, all of which
shall be certified by Tenant to be complete, true and correct. Landlord's
receipt of Landlord's Share shall not be a consent to any further assignment or
subletting. The breach of Tenant's obligation under this Paragraph 9.05(b) shall
be a material default of the Lease.

     Section 9.06.  NO MERGER. No merger shall result from Tenant's sublease of
the Property under this Article Nine, Tenant's surrender of this Lease or the
termination of this Lease in any other manner,. In any such event, Landlord may
terminate any or all subtenancies or succeed to the interest of Tenant as
sublandlord under any or all subtenancies.

ARTICLE TEN:  DEFAULTS; REMEDIES

     Section 10.01. COVENANTS AND CONDITIONS. Tenant's performance of each of
Tenant's obligations under this Lease is a condition as well as a covenant.
Tenant's right to continue in possession of the Property is conditioned upon
such performance. Time is of the essence in the performance of all covenants and
conditions.

     Section 10.01. DEFAULTS. Tenant shall be in material default under this
Lease:

          (a)  If Tenant abandons the Property or if Tenant's vacation of the
Property results in the cancellation of any insurance described in Section 4.04;

          (b)  If Tenant fails to pay rent or any other charge when due;

          (c)  If Tenant fails to perform any of Tenant's non-monetary
obligations under this Lease for a period of thirty (30) days after written
notice from Landlord; provided that if more than thirty (30) days are required
to complete such performance, Tenant shall not be in default if Tenant commences
such performance within the thirty (30) day period and thereafter diligently
pursues its completion. However, Landlord shall not be required to give such
notice if Tenant's failure to perform constitutes a non-curable breach of this
Lease. The notice required by this Paragraph is intended to satisfy any and all
notice requirements imposed by law on Landlord and is not in addition to any
such requirement.

          (d)  (i)  If Tenant makes a general assignment or general arrangement
for the benefit of creditors; (ii) if a petition for adjudication of bankruptcy
or for reorganization or rearrangement is filed by or against Tenant and is not
dismissed within thirty (30) days; (iii) if a trustee or receiver is appointed
to take possession of substantially all of Tenant's assets located at the
Property or of Tenant's interest in this Lease and possession is not restored to
Tenant within thirty (30) days; or (iv) if substantially all of Tenant's assets
located at the Property or of Tenant's interest in this Lease is subjected to
attachment, execution or other judicial seizure which is not discharged within
thirty (30) days. If a court of competent jurisdiction determines that any of
the acts described in this subparagraph (d) is not a default under this Lease,
and a trustee is appointed to take possession (or if Tenant remains a debtor in
possession) and such trustee or Tenant transfers Tenant's interest hereunder,
then Landlord shall receive, as Additional

                                       17
<PAGE>
 
Rent, the excess, if any, of the rent (or any other consideration) paid in
connection with such assignment or sublease over the rent payable by Tenant
under this Lease.

          (e)  If any guarantor of the Lease revokes or otherwise terminates, or
purports to revoke or otherwise terminate, any guaranty of all or any portion of
Tenant's obligations under the Lease. Unless otherwise expressly provided, no
guaranty of the Lease is revocable.

     Section 10.3.  REMEDIES. On the occurrence of any material default by
Tenant, Landlord may, at any time thereafter, with or without notice or demand
and without limiting Landlord in the exercise of any right or remedy which
Landlord may have:

          (a)  Terminate Tenant's right to possession of the Property by any
lawful means, in which case this Lease shall terminate and Tenant shall
immediately surrender possession of the Property to Landlord. In such event,
Landlord shall be entitled to recover from Tenant all damages incurred by
Landlord by reason of Tenant's default, including (i) the worth at the time of
the award of the unpaid Base Rent, Additional Rent and other charges which
Landlord had earned at the time of the termination; (ii) the worth at the time
of the award of the amount by which the unpaid Base Rent, Additional Rent and
other charges which Landlord would have earned after termination until the time
of the award exceeds the amount of such rental loss that Tenant proves Landlord
could have reasonably avoided; (iii) the worth at the time of the award of the
amount by which the unpaid Base Rent, Additional Rent and other charges which
Tenant would have paid for the balance of the Lease Term after the time of award
exceeds the amount of such rental loss that Tenant proves Landlord could have
reasonably avoided; and (iv) any other amount necessary to compensate Landlord
for all the detriment proximately caused by Tenant's failure to perform its
obligations under the Lease or which in the ordinary course of things would be
likely to result therefrom, including, but not limited to, any costs or expenses
Landlord incurs in maintaining or preserving the Property after such default,
the cost of recovering possession of the Property, expenses of reletting,
including necessary renovation or alteration of the Property, Landlord's
reasonable attorneys' fees incurred in connection therewith, and any real estate
commission paid or payable. As used in subparts (i) and (ii) above, the "worth
at the time of the award" is computed by allowing interest on unpaid amounts at
the rate of fifteen percent (15%) per annum, or such lesser amount as may then
be the maximum lawful rate. As used in subpart (iii) above, the "worth at the
time of the award" is computed by discounting such amount at the discount rate
of the Federal Reserve Bank of San Francisco at the time of the award, plus one
percent (1%). If Tenant has abandoned the Property, Landlord shall have the
option or (i) retaking possession of the Property and recovering from Tenant the
amount specified in this Paragraph 10.03(a), or (ii) proceeding under Paragraph
10.03(b).

          (b)  Maintain Tenant's right to possession, in which case this Lease
shall continue in effect whether or not Tenant has abandoned the Property. In
such event, Landlord shall be entitled to enforce all of Landlord's rights and
remedies under this Lease, including the right to recover the rent as it becomes
due;

          (c)  Pursue any other remedy now or hereafter available to Landlord
under the laws or judicial decisions of the state in which the Property is
located.

                                       18
<PAGE>
 
     Section 10.04. REPAYMENT OF "FREE" RENT. If this Lease provides for a
postponement of any monthly rental payments a period of "free" rent or other
rent concession, such postponed rent or "free" rent is called the "Abated Rent".
Tenant shall be credited with having paid all of the Abated Rent on the
expiration on the Lease Term only if Tenant has fully, faithfully, and
punctually performed all of Tenant's obligations hereunder, including the
payment of all rent (other than the Abated Rent) and all other monetary
obligations and the surrender of the Property in the physical condition required
by this Lease. Tenant acknowledges that its right to receive credit for the
Abated Rent is absolutely conditioned upon Tenant's full, faithful and punctual
performance of its obligations under this Lease. If Tenant defaults and does not
cure within any applicable grace period, the Abated Rent shall immediately
become due and payable in full and this Lease shall be enforced as if there were
no such rent abatement or other rent concession. In such case Abated Rent shall
be calculated based on the full initial rent payable under this Lease.

     Section 10.05. AUTOMATIC TERMINATION. Notwithstanding any other term or
provision hereof to the contrary, the Lease shall terminate on the occurrence of
any act which affirms the Landlord's intention to terminate the Lease as
provided in Section 10.03 hereof, including the filing of an unlawful detainer
action against Tenant. On such termination, Landlord's damages for default shall
include all costs and fees, including reasonable attorneys' fees that Landlord
incurs in connection with the filing, commencement, pursuing and/or defending of
any action in any bankruptcy court or other court with respect to the Lease; the
obtaining of relief from any stay in bankruptcy restraining any action to evict
Tenant; or the pursing of any action with respect to Landlord's right to
possession of the Property. All such damages suffered (apart from Base Rent and
other rent payable hereunder) shall constitute pecuniary damages which must be
reimbursed to Landlord prior to assumption of the Lease by Tenant or any
successor to Tenant in any bankruptcy or other proceeding.

     Section 10.06. CUMULATIVE REMEDIES.  Landlord's exercise of any right or
remedy shall not prevent it from exercising any other right or remedy.

ARTICLE ELEVEN:  PROTECTION OF LENDERS

     Section 11.01. SUBORDINATION. Landlord shall have the right to subordinate
this Lease to any ground lease, deed of trust or mortgage encumbering the
Property, any advances made on the security thereof and any renewals,
modifications, consolidations, replacements or extensions thereof, whenever made
or recorded. Tenant shall cooperate with Landlord and any lender which is
acquiring a security interest in the Property or the Lease. Tenant shall execute
such further documents and assurances as such lender may require, provided that
Tenant's obligations under this Lease shall not be increased in any material way
(the performance of ministerial acts shall not be deemed material), and Tenant
shall not be deprived of its rights under this Lease. Tenant's right to quiet
possession of the Property during the Lease Term shall not be disturbed if
Tenant pays the rent and performs all of Tenant's obligations under this Lease
and is not otherwise in default. If any ground lessor, beneficiary or mortgagee
elects to have this Lease prior to the lien of its ground lease, deed of trust
or mortgage and gives written notice thereof to Tenant, this Lease shall be
deemed prior to such ground lease, deed of trust or mortgage whether

                                       19
<PAGE>
 
this Lease is dated prior or subsequent to the date of said ground lease, deed
of trust or mortgage or the date of recording thereof.

     Section 11.02. ATTORNMENT. If Landlord's interest in the Property is
acquired by any ground lessor, beneficiary under a deed of trust, mortgagee, or
purchaser at a foreclosure sale, Tenant shall attorn to the transferee of or
successor to Landlord's interest in the Property and recognize such transferee
or successor as Landlord under this Lease. Tenant waives the protection of any
statute or rule of law which gives or purports to give Tenant any right to
terminate this Lease or surrender possession of the Property upon the transfer
of Landlord's interest.

     Section 11.03. SIGNING OF DOCUMENTS. Tenant shall sign and deliver any
instrument or documents necessary or appropriate to evidence any such attornment
or subordination or agreement to do so. If Tenant fails to do so within ten (10)
days after written request, Tenant hereby makes, constitutes and irrevocably
appoints Landlord, or any transferee or successor of Landlord, the attorney-in-
fact of Tenant to execute and deliver any such instrument or document.

     Section 11.04. ESTOPPEL CERTIFICATES.

          (a)  Upon Landlord's written request, Tenant shall execute,
acknowledge and deliver to Landlord a written statement certifying: (i) that
none of the terms or provisions of this Lease have been changed (or if they have
been changed, stating how they have been changed); (ii) that this Lease has not
been cancelled or terminated; (iii) the last date of payment of the Base Rent
and other charges and the time period covered by such payment; (iv) that
Landlord is not in default under this Lease (or, if Landlord is claimed to be in
default, stating why); and (v) such other representations or information with
respect to Tenant or the Lease as Landlord may reasonably request or which any
prospective purchase or encumbrancer of the Property may require. Tenant shall
deliver such statement to Landlord within ten (10) days after Landlord's
request. Landlord may give any such statement by Tenant to any prospective
purchaser or encumbrancer of the Property. Such purchaser or encumbrancer may
rely conclusively upon such statement as true and correct.

          (b)  If Tenant does not deliver such statement to Landlord within such
ten (10) day period, Landlord, and any prospective purchaser or encumbrancer,
may conclusively presume and rely upon the following facts: (i) that the terms
and provisions of this Lease have not been changed except as otherwise
represented by Landlord; (ii) that this Lease has not been cancelled or
terminated except as otherwise represented by Landlord; (iii) that not more than
one month's Base Rent or other charges have been paid in advance; and (iv) that
Landlord is not in default under the Lease. In such event, Tenant shall be
estopped from denying the truth of such facts.

     Section 11.05. TENANT'S FINANCIAL CONDITION. Within ten (10) days after
written request from Landlord, Tenant shall deliver to Landlord such financial
statements as Landlord reasonably requires to verify the net worth of Tenant or
any assignee, subtenant, or guarantor of Tenant. In addition, Tenant shall
deliver to any lender designated by Landlord any financial statements required
by such lender to facilitate the financing or refinancing of the Property.

                                       20
<PAGE>
 
Tenant represents and warrants to Landlord that each such financial statement is
a true and accurate statement as of the date of such statement. All financial
statements shall be confidential and shall be used only for the purposes set
forth in this Lease.

ARTICLE TWELVE:  LEGAL COSTS.

     Section 12.01. LEGAL PROCEEDINGS. If Tenant or Landlord shall be in breach
or default under this Lease, such party (the "Defaulting Party") shall reimburse
the other party (the "Nondefaulting Party") upon demand for any costs or
expenses that the Nondefaulting Party incurs in connection with any breach or
default of the Defaulting Party under this Lease, whether or not suit is
commenced or judgment entered. Such costs shall include legal fees and costs
incurred for the negotiation of a settlement, enforcement of rights or
otherwise. Furthermore, if any action for breach of or to enforce the provisions
of this Lease is commenced, the court in such action shall award to the party in
whose favor a judgment is entered, a reasonable sum and attorneys' fees and
costs. The losing party in such action shall pay such attorneys' fees and costs.
Tenant shall also indemnify Landlord against and hold Landlord harmless from all
costs, expenses, demands and liability Landlord may incur if Landlord becomes or
is made a party to any claim or action (a) instituted by Tenant against any
third party, or by any third party against Tenant, or by or against any person
holding any interest under or using the Property by license of or agreement with
Tenant; (b) for foreclosure of any lien for labor material furnished to or for
Tenant or such other person; (c) otherwise arising out of or resulting from any
act or transaction of Tenant or such other person; or (d) necessary to protect
Landlord's interest under this Lease in a bankruptcy proceeding, or other
proceeding under Title 11 of the United States Code, as amended. Tenant shall
defend Landlord against any such claim or action at Tenant's expense with
counsel reasonably acceptable to Landlord or, at Landlord's election, Tenant
shall reimburse Landlord for any legal fees or costs Landlord incurs in any such
claim or action.

     Section 12.02. LANDLORD'S CONSENT. Tenant shall pay Landlord's reasonable
attorneys' fees incurred in connection with Tenant's request for Landlord's
consent under Article Nine (Assignment and Subletting), or in connection with
any other act which Tenant proposes to do and which requires Landlord's consent.

ARTICLE THIRTEEN:  MISCELLANEOUS PROVISIONS

     Section 13.01. NON-DISCRIMINATION. Tenant promises, and it is a condition
to the continuance of this Lease, that there will be no discrimination against,
or segregation of any person or group of persons on the basis of race, color,
sex, creed, national origin or ancestry in the leasing, subleasing,
transferring, occupancy, tenure or use of the Property or any portion thereof.

     Section 13.02. LANDLORD'S LIABILITY; CERTAIN DUTIES.

          (a)  As used in this Lease, the term "Landlord" means only the current
owner or owners of the fee title to the Property or Project or the leasehold
estate under a ground lease of the Property or Project at the time in question.
Each Landlord is obligated to perform the obligations of landlord under this
Lease only during the time such Landlord owns such interest or

                                       21
<PAGE>
 
little. Any Landlord who transfers its title or interest is relieved of all
liability with respect to the obligations of Landlord under this Lease to be
performed on or after the date of transfer. However, each Landlord shall deliver
to its transferee all funds that Tenant previously paid if such funds have not
yet been applied under the terms of this Lease.

          (b)  Tenant shall give written notice of any failure by Landlord to
perform any of its obligations under this Lease to Landlord and to any ground
lessor, mortgagee or beneficiary under any deed of trust encumbering the
Property whose name and address have been furnished to Tenant in writing.
Landlord shall not be in default under this Lease unless Landlord (or such
ground lessor, mortgagee or beneficiary) fails to cure such non-performance
within thirty (30) days after receipt of Tenant's notice. However, if such non-
performance reasonably requires more than thirty (30) days to cure, Landlord
shall not be in default if such cure is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

          (c)  Notwithstanding any term or provision herein to the contrary, the
liability of Landlord for the performance of its duties and obligations under
this Lease is limited to Landlord's interest in the Property and the Project,
and neither the Landlord nor its partners, shareholders, officers or other
principals shall have any personal liability under this Lease.

     Section 13.03. SEVERABILITY. A determination by a court of competent
jurisdiction that any provision of this Lease or any part thereof is illegal or
unenforceable shall not cancel or invalidate the remainder of such provision of
this Lease, which shall remain in full force and effect.

     Section 13.04. INTERPRETATION. The captions of the Articles or Sections of
this Lease are to assist the parties in reading this Lease and are not a pat of
the terms or provisions of this Lease. Whenever required by the context of this
Lease, the singular shall include the plural and the plural shall include the
singular. The masculine, feminine and neuter genders shall each include each
other. In any provision relating to the conduct, acts or omissions of Tenant,
the term "Tenant" shall include Tenant's agents, employees, contractors,
invitees, successors or others using the Property with Tenant's expressed or
implied permission.

     Section 13.05. INCORPORATION OF PRIOR AGREEMENTS; MODIFICATIONS. This Lease

may change its notice address upon written notice to the other party.

                                       22
<PAGE>
 
     Section 13.07. WAIVERS. All waivers must be in writing and signed by the
waiving party. Landlord's failure to enforce any provision of this Lease or its
acceptance of rent shall not be a waiver and shall not prevent Landlord from
enforcing that provision or any other provision of this Lease in the future. No
statement on a payment check from Tenant or in a letter accompanying a payment
check shall be binding on Landlord. Landlord may, with or without notice to
Tenant, negotiate such check without being bound to the conditions of such
statement.

     Section 13.08. NO RECORDATION. Tenant shall not record this Lease without
prior written consent from Landlord. However, either Landlord or Tenant may
require that a "Short Form" memorandum of this Lease executed by both parties be
recorded. The party requiring such recording shall pay all transfer taxes and
recording fees.

     Section 13.09. BINDING EFFECT; CHOICE OF LAW. This Lease binds any part who
legally acquires any rights or interest in this Lease from Landlord or Tenant.
However, Landlord shall have no obligation to Tenant's successor unless the
rights or interests of Tenant's successor are acquired in accordance with the
terms of this Lease. The laws of the state in which the Property is located
shall govern this Lease.

     Section 13.10. CORPORATE AUTHORITY; PARTNERSHIP AUTHORITY. If Tenant is a
corporation, each person signing this Lease on behalf of Tenant represents and
warrants that he has full authority to do so and that this Lease binds the
corporation. Within thirty (30) days after this Lease is signed, Tenant shall
deliver to Landlord a certified copy of a resolution of Tenant's Board of
Directors authorizing the execution of this Lease or other evidence of such
authority reasonably acceptable to Landlord. If Tenant is a partnership, each
person or entity signing this Lease for Tenant represents and warrants that he
or it is a general partner of the partnership, that he or it has full authority
to sign for the partnership and that this Lease binds the partnership and all
general partners of the partnership. Tenant shall give written notice to
Landlord of any general partner's withdrawal or addition. Within thirty (30)
days after this Lease is signed, Tenant shall deliver to Landlord a copy of
Tenant's recorded statement of partnership or certificate of limited
partnership.

     Section 13.11. JOINT AND SEVERAL LIABILITY. All parties signing this Lease
as Tenant shall be jointly and severally liable for the obligations of Tenant.

     Section 13.12. FORCE MAJEURE. If Landlord cannot perform any of its
obligations due to events beyond Landlord's control, the time provided for
performing such obligations shall be extended by a period of time equal to the
duration of such events. Events beyond Landlord's control include, but are not
limited to, acts of God, war, civil commotion, labor disputes, strikes, fire,
flood or other casualty, shortages of labor or material, government regulation
or restriction and weather conditions.

     Section 13.13. EXECUTION OF LEASE. This Lease may be executed in
counterparts and, when all counterpart documents are executed, the counterparts
shall constitute a single binding instrument. Landlord's delivery of this Lease
to Tenant shall not be deemed to be an offer to lease and shall not be binding
upon either party until executed and delivered by both parties.

                                       23
<PAGE>
 
     Section 13.14. SURVIVAL.  All representations and warranties of Landlord
and Tenant shall survive the termination of this Lease.

ARTICLE FOURTEEN:  BROKERS

Paragraph E on page 1 of the Lease multiplied by the total number of square feet
of Rentable Area. Tenant acknowledges that Landlord has not made any
representation or given Tenant any assurance that Base Operating Expenses will
equal or approximate the actual Operating

                                       3
<PAGE>
 
Expenses for any Lease Year, including the first Lease Year.

          (2)  "RENTABLE AREA" - all rentable space available for lease in the

be necessary to reflect any such change.

          (3)  "TENANT'S PRO RATE SHARE" - Tenant's percentage portion of
increases in Operating Expenses as such percentage is specified in Paragraph E
on page 1 of this Lease. If at any time during the Lease Term, Tenant leases
additional space in the Building, Tenant's Pro Rata Share shall be recomputed by
dividing the total rentable square footage of space then being leased by Tenant
(including the Additional space) by the Rentable Area and the resulting
percentage figure shall then become Tenant's Pro Rata Share.

          (4)  "LANDLORD'S ACCOUNTANTS" - the individual or firm employed by
Landlord from time to time to keep the books and records for the Building and
Common Area and/or to prepare the federal and state income tax returns for

nature determined in accordance with sound accounting practice as applied to the
operation and maintenance of first class office buildings in the metropolitan

Building and/or Common Areas by any governmental or quasi-governmental
authority, including ny taxes, impositions, or assessments of a nature not

as a result of the use, ownership or operation of the Building and/or Common
Areas, or for any other reason, whether in lieu of, or in addition to, any
current real estate taxes and assessments, provided, that (i) any taxes levied
on the rentals of the Building shall be determined as if the Building were
Landlord's only property and, (ii) in no event shall "taxes or assessments"
include any net federal or state income taxes levied or assessed on Landlord
unless such taxes are a specific substitute for real property taxes (such term
shall, however, include gross tax an rentals); expenses incurred by Landlord for
tax consultants and in contesting the amount or validity of any such taxes or
assessments shall be also included in such computations (all of the foregoing
are collectively referred to as "TAXES");

          (b)  Costs of supplies, including, without limitation, costs of
relamping all standard building tenant lighting as required from time to time;

          (c)  Costs in connection with obtaining and providing energy for the
Building, including, without limitation, costs of propane, butane, natural gas,
steam, electricity, solar energy and fuel oils, or coal;

          (d)  Costs of water and sanitary and storm drainage services,

          (e)  Costs of security services and of managing and operating any

equipment used in connection with such maintenance and repair work;

          (g)  Costs of maintenance and replacement of landscaping;

          (h)  Insurance premiums, including fire and all-risk coverage,
together with loss of rent endorsement, the part of any claim required to be
paid under the deductible portion of any insurance policy carded by Landlord in
connection with the Building or Common Areas or their component parts (where
Landlord is unable to obtain insurance without such deductible from a major
insurance carrier at reasonable rates), public liability insurance, and any
other insurance carried by Landlord on the Building or Common Area or their
component parts (all such insurance shall be in such amounts as Landlord may
reasonably determine);

          (i)  Labor costs, including wages and other payments, costs to
Landlord of workmen's compensation and disability insurance, payroll taxes,
welfare fringe benefits, and all legal fees and other costs or expenses incurred
in resolving any labor dispute;

IMPROVEMENTS"); costs of any capital improvements and structural repairs and
replacements designed primarily to reduce Operating Expenses ("COST SAVINGS
IMPROVEMENTS"); and a reasonable annual reserve for all other capital
improvements and structural repairs and replacements reasonably necessary to
permit Landlord to maintain the Building as a first class office building. The
expenditures for Required Capital Improvements and Cost Savings Improvements
shall be amortized at a market rate of return over their useful life, as
reasonably detertnined by Landlord's Accountants, provided that the amortized
amount of any Cost Savings Improvement shall be limited in any year to the
reduction in Operating Expenses as a result thereof.

"Operating Expenses" shall not include: (i) costs of any work, including
painting, decorating and tenant-change work, which Landlord performs for any
tenant or in any tenant's space in the Building other than work of a kind and
scope which Landlord would be obligated to furnish to all tenants whose leases
contain a rental adjustment provision and services provision similar to those
herein; (ii) costs of repairs or other work occasioned by fire, windstorm or
other insured casualty to the extent of insurance proceeds received; (iii)
leasing commissions, advertising expenses and other costs incurred in leasing
space in the Building; (iv) costs of repairs or rebuilding necessitated by
condemnation; (v) interest on borrowed money or debt amortization, except as
specifically set forth above; or (vi) depreciation on the Building.

          B.  As provided below, for each calendar year of the Lease Term
(including the calendar year in which the Lease Term commences) Tenant shall pay
to Landlord Tenant's Pro Rata Share of the amount of the increase in the
Operating Expenses for the calendar year just completed over Base Operating
Expenses and shall also pay to Landlord monthly during each calendar year
following the year in which the Lease Term commences, an estimate of Tenant's
Pro Rata Share of the amount by which actual Operating

                                       5
<PAGE>
 
Expenses attributable to the calendar year during which such amounts are paid
will exceed the Base Operating Expenses. As soon as practicable after the end of
each calendar year during the Lease Term, beginning with the end of the calendar
year in which the Lease Term commences, Landlord shall submit to Tenant a
statement setting forth: (i) the amount of the increase, if any, in the amount
of Tenant's Pro Rate Share for the calendar year just completed over Base
Operating Expenses, and (ii) for each calendar year following the year in which
the Lease Term commences, the difference, if any, between the amount of Tenant's
actual Pro Rata Share of the Operating Expenses for the calendar year just
completed and the estimated amount of Tenant's Pro Rata Share of the increases
paid for that year. Each statement shall also set forth the amount of the
estimated increases in Operating Expenses over Base Operating Expenses for the
new calendar year computed in accordance with the foregoing. To the extent that
the amount of Tenant's Pro Rata Share of actual increases for the period covered
by such statement is higher than Tenant's payments (if any) of its Pro Rata
Share of the estimated increases for the calendar year just completed, Tenant
shall pay to Landlord the difference in cash within 30 days following receipt of
the statement from Landlord. If, however, the amount of Tenant's Pro Rata Share
of the actual increases for the period covered by the statement is less than the
amount of Tenant's Pro Rata Share of the estimated increases paid during the
calendar year just completed, Landlord shall credit the difference against the
Tenant's estimated payment for such Operating Expenses for the current year.
Until Tenant receives each such statement, Tenant shall continue to pay the
amount required for the prior year, but Tenant shall commence payment to
Landlord of the monthly installments of such estimates on the basis of the
statement beginning on the first day of the month following the month in which
Tenant receives such statement. Tenant shall also pay to Landlord or deduct from
the rent, as the case may be; the difference, if any, between the monthly
installments of rent, so adjusted, for the new year and the monthly
installments of rent actually paid during the new year.

          C.  Tenant's obligation with respect to payment of its Pro Rata Share
of increases shall survive the expiration or early termination of this Lease and
Landlord shall have the right to retain the Security Deposit, or so much of it
as it deems necessary, to secure such payment attributable to the year in which
this Lease terminates. If this Lease is in effect for less than a full calendar
year during the first or last calendar year of the Lease Term, Tenant's Pro Rata
Share for such partial year shall be calculated by proportionately reducing the
Base Operating Expenses to reflect the number of months in iuch year during
which this Lease was in effect (the "Adjusted Base Operating Expenses"), and the
Adjusted Base Operating Expenses shall then be compared with the actual
Operating Expenses for that partial year to determine the amount, if any, of any
increases in the actual Operating Expenses for such partial year over the
Adjusted Base Operating Expenses.

          D.  Tenant shall have the right within 30 days after a statement of
actual Operating Expenses for a particular calendar year has been rendered by
Landlord, upon notice to Landlord, at Tenant's sole cost, to examine Landlord's
books and records relating to the determination of these Operating Expenses.
Unless Tenant objects to the resulting rental adjustment within the 30-day
period, the statement and adjustment shall be deemed conclusive.

          E.  In computing increases any special assessments shall be deemed
payable in such number of installments as permitted by law, whether or not
actually so paid. If the Building has not been fully assessed as a completed
structure, then for the purposes of computing the Operating Expenses for any
adjustment herein, Taxes shall be adjusted by Landlord as of the date on which
the adjustment is to be made to reflect full completion of the Building
including installation of Tenant Finish

                                       6
<PAGE>
 
Work for all Rentable Area. If any lease entered into by Landlord with any
tenant in the Building is on a so-called "net" basis, or provides for a separate
basis of computation for any Operating Expenses, then, to the extent that
Landlord's Accountants determine that an adjustment should be made in making the
computations herein, Landlord's Accountants shall be permitted to modify the
computation of Base Operating Expenses, Rentable Area, and Operating Expenses
for a particular Lease Year in order to eliminate or otherwise modify any such
expenses which are paid for in whole or in part by such tenant. In making the
computations above Landlord's Accountants shall also be permitted to make such
adjustments and modifications to the provisions of this Section as shall be
reasonably necessary to achieve the intention of the parties. If the Rentable
Area is not fully occupied during a Lease Year, Landlord's Accountants may
reasonably adjust those Operating Expenses which are affected by the occupancy
rates for that Lease Year, or portion thereof, as the case may be, to reflect
full occupancy.

          F.  The Rentable Area, the Base Rent, and Tenant's Pro Rata Share may
be appropriately recalculated and adjusted in the event that the Building and/or
Premises are measured upon completion and it is determined that the square
footage of the Building and/or Premises differs from those figures set forth on
page I of this Lease.

          G.  Tenant shall at its sole cost and expense, separately contract for
and provide janitorial service to the Premises. Landlord may impose reasonable
rules, regulations and requirements on such janitorial service.

          H.  Tenant acknowledges that the Premises together with adjacent space
currently leased by General Electric Company (the "GE Space") are collectively
seperately metered for electrical power. Because of the prohibitive cost of
seperately metering the Premises and the GE Space, Landlord will not separately
meter the Premises. In lieu of such seperate metering, Landlord shall have the
electricity metered in Landlord's name and seperately bill Tenant and such
tenant as leases the GE Space for alectjical usage on a pro rate basis based on
the rentable square footage of each tenant Based on that formula, commencing
with the commencement of the Lease, Tenant would be responsible for 38% (5,960 +
15,690) of the electrical cost billed to Landlord. During such time as the GE
Space is unoccupied by a subsequent tenant, Tenant shall be responsible for all
of the electrical bill to Landlord, less an appropriate deduction, such
deduction to be reasonably determined and agreed upon between Tenant and
Landlord, for the electrical consumption that is required for the GE Space when
vacant. If the use of the Premises or the GE Space increase from Ordinary
Business Hours, Landlord shall make reasonable adjustments so that Tenant is
paying for an equitable pro ration of the electrical consumption. Any amounts
billed to Tenant by Landlord pursuant to this subparagraph H are in addition to
any other amounts paid to Landlord by Tenant pursuant to Section 3 of the Lease.

 Section 4.  SERVICES.
             -------- 

             A.  Subject to the provisions of D below, Landlord agrees, without
charge except as provided in this Lease, and in accordance with those standards
prevailing from time to time for the Building: (1) to furnish running water at
those points of supply for general use of tenants of the Building, heated and
cooled air, electrical current, janitorial services and such maintenance as
Landlord reasonably deems necessary for all Common Areas; (2) to furnish, during
Ordinary Business Hours such heated or cooled air to the Premises as may, in the
reasonable judgment of Landlord, be required for the comfortable use and
occupancy of the Premises, provided that the recommendations of Landlord's
engineer regarding occupancy and use of the Premises are complied with by
Tenant, and cooled air is used only for standard office use; (3) if the Building
is equipped with elevators, to provide,

                                       7
<PAGE>
 
during Ordinary Business Hours, non-exclusive use of a passenger elevator for
access to and from the Premises (with at least one such elevator being available
at all times except in the case of emergencies or repair); (4) to provide
janitorial services for the Premises to the extent of the Standard Tenant Finish
items contained therein (including such window washing of the outside of
exterior windows as may, in the judgment of Landlord, be reasonably required),
but unless and until Building standard changes, such janitorial services will be
provided after business hours only on Monday through Friday, excluding Legal
Holidays; and (5) to cause electric power to be supplied to the Premises for
building standard fluorescent lighting and for general purpose 120 volt single-
phase plug-in power for ordinary office usage, but in any event, the combination
of both are not to exceed 5 watts per useable square foot per National Electric
Code connected load requirements ("PERMITTED POWER"). "ORDINARY BUSINESS HOURS"
shall be 7:00 a.m. to 6:00 p.m. Monday through Friday and 9:00 a.m. to 12:00
p.m. on Saturdays, Legal Holidays excepted. "LEGAL HOLIDAYS" shall mean New
Year's day, Presidents' Day, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, Christmas Day, and such other national holidays as may be
established by the federal government.

          B.  To the extent (a) electric current in excess of Permitted Power is
used for any machinery, equipment or otherwise in the operation of the Premises,
(b) electric current is used in the Promises at times other than Ordinary
Business Hours, or (c) any use of machinery or equipment would overload Building
facilities (or would result in an imbalance in the HVAC systems designed for the
Building), then and in each such case Tenant's rent may be increased by Landlord
in such amounts as Landlord reasonably determines necessary to cover the
increased cost resulting from such uses, including additional air conditioning
costs and other ancillary costs incurred by Landlord attributable to any such
uses (including costs required to make such service available to the Premises).
Such increases shall be paid monthly with the monthly rental installment. Tenant
shall also reimburse Landlord for all costs of modifying the Building HVAC
system and/or extending or modifying any electrical service as Landlord may
reasonably determine is necessary as a result of Tenant's excess usage. Before
installation or use by Tenant of any equipment other than that which utilizes
only Permitted Power, or operation of the Premises for extended hours on an
ongoing basis, Tenant shall notify Landlord of such intended installation or
use, and obtain Landlord's consent. In addition to the foregoing, Landlord may,
at Landlord's option, then or at any time thereafter, require Tenant, at
Tenant's sole cost and expense, to install a check meter to assist in
determining the amount by which Tenant's rent should be increased. If Tenant
desires electric current or heated or cooled air to the Premises during periods
other than Ordinary Business Hours, Landlord will use reasonable efforts to
supply such services, but at the expense of Tenant at Landlord's standard rate
as reasonably established by it from time to time for such services. Not less
than 48 hours prior notice shall be given to Landlord of Tenant's desire for
these additional services. Tenant shall also pay the cost of replacing light
bulbs or tubes used in all non-standard Building lighting in the Premises.

          C.  If Tenant requests janitorial services other than those standard
services provided to other tenants of the Building, Tenant shall separately pay
for such service monthly upon billing by Landlord, or, at Landlord's option,
Tenant shall separately contract for such services with the same company
furnishing janitorial services to Landlord. Tenant shall have the right, subject
to Landlord's prior written consent and'such rules, regulations and requirements
as Landlord may reasonably impose (including, but not limited to, the
requirement thatsuch janitors belong to a trade union), to employ janitors other
than those employed by Landlord to perform such additional services.

                                       8
<PAGE>
 
          D.  Landlord shall not be liable for failure to supply heating, air
conditioning, elevator, electrical, janitorial, lighting or other services
during any period as long as Landlord is using reasonable diligence to supply
such services, or during any period Landlord is required to reduce or curtail
such services pursuant to any applicable laws, rules or regulations, including
utility regulations, it being agreed that such services may be discontinued,
reduced or curtailed (either temporarily or permanently) at such times as may be
necessary by reason of accident, repairs, alterations, improvements, strikes,
lockouts, riots, acts of God, application of applicable laws, rules and
regulations, or any other happening beyond the control of Landlord. In the event
of an interruption, reduction, or discontinuance of services (either temporary
or permanent) as set forth above, Landlord shall neither be liable for damages
to person or property as a result thereof nor shall the occurrence of any such
event in any way be construed as an eviction of Tenant, cause or permit an
abatement, reduction, or setoff of rent, or operate to release Tenant from any
of its obligations under this Lease.

          E  Tenant shall promptly notify the Landlord (or its representative)
of any accidents or defects in the Building of which Tenant becomes aware,
including defects in pipes, electric wiring, and HVAC equipment, and provide
Landlord with prompt notification of any condition of which it becomes aware
which may cause injury or damage to the Building or any person or property
therein.

 Section 5.  SECURITY DEPOSIT.
             ----------------

             Concurrent with the execution of this Lease, Tenant shall deposit
with Landlord, and will keep on deposit at all times during the term of this
Lease, the amount set forth:in Paragraph F on page 1 of this Lease, as security
for the payment by Tenant of all rent and other amounts agreed to be paid and
for the performance of all the terms and conditions of this Lease to be
performed by Tenant. If Tenant shall be in default in the performance of any
provision of this Lease, Landlord shall have the right to use the deposit, or so
much as is necessary, in payment of any, rent or other amounts in default,
reimbursement of expenses incurred by Landlord, and payment of damages incurred
by Landlord by reason of Tenant's default. In such event, Tenant shall, on
written demand of Landlord, promptly remit to Landlord a sufficient amount in
cash to restore the deposit to its original amount If the deposit is not
utilized, it (or as much thereof as has not been utilized for such purposes)
shall be refunded to Tenant, or to whoever is than the holder of Tenant's
interest in this Lease, without interest, upon full performance of this Lease by
Tenant. Landlord shall have the right to commingle the deposit with other funds
of Landlord and need not keep it in a trust account Landlord may deliver the
deposit to the purchaser of Landlord's interest in the Premises in the event
such interest be sold, and Landlord shall then be discharged from further
liability with respect to it. If claims of Landlord exceed the deposit, Tenant
shall remain liable for the balance of such claims.

 Section 6.  CHARACTER OF OCCUPANCY.
             ----------------------

             Tenant shall: occupy the Premises only for the purpose set forth in
Paragraph D on Page 1 of this Lease for no other purpose; use them in a careful,
safe and proper manner; pay on demand for any damage to the Premises caused by
misuse or abuse thereof by Tenant, Tenant's agents or employees, or of any other
person entering upon the Premises under express or implied invitation of Tenant;

purposes prohibited by, the laws, codes, rules and regulations of any
governmental authority having jurisdiction feven if the foregoing shall
necessitate

changes or modificafions within the Premises) or the provisions of the
restrictive covenants affecting the Building and not permit any nuisance on or
in the Premises. Tenant shall allow no use to be made of the Premises which will
cause the cancellation of any insurance policy covering the Premises or the
Building, and if the particular use to which the Tenant puts the Premises
causes an increase in insurance rates, Tenant shall pay any such increase.

 Section 7.  ALTERATIONS AND REENTRY BY LANDLORD.
             ----------------------------------- 

             A.  Unless otherwise expressly provided herein Landlord shall not
be required to make any modifications, improvements or repairs of any kind or
character to the Premises during the Lease Term, except such repairs to the
base, shelf and core of the Building, the roof, building standard HVAC,
electrical and plumbing facilities and Common Areas as may be deemed necessary
by Landlord for normal maintenance operations of the Building and Common Areas
(so long as the need for such repairs is not the result of Tenant's negligence)
and provided such obligation shall not include the interior surface of exterior
walls, windows, doors, or interior plate glass. Tenant agrees that for the
purposes of completing or making repairs or alterations in any portion of the
Building, Landlord may use one or more of the street entrances, the halls,
passageways and elevators of the Building.

             B.  Tenant shall permit Landlord to enter the Premises at any time
upon reasonable notice to Tenant to show the Premises for leasing or to examine
and inspect the same or, if Landlord so elects, to perform any obligations of
Tenant hereunder which Tenant shall fail to perform or to perform such cleaning,
maintenance, janitorial services, repairs, additions or alterations as Landlord
may deem necessary or proper for the safety, improvement or preservation of the
Premises or of other portions of the Building and Common Areas or as may be
required by governmental authorities. Any such reentry shall not constitute an
eviction or entitle Tenant to abatement of rent. Landlord shall have the right
at its election to make such alterations or changes in other portions of the
Building and Common Areas as Landlord may from time to time deem necessary and
desirable as long as such alterations and changes do not unreasonably interfere
with Tenant's use and occupancy of the Premises.

 Section 8.  ALTERATIONS AND REPAIRS BY TENANT.
             --------------------------------- 

             A.  Tenant shall not make any alterations in or additions to the
Premises (subsequent to the work in the Premises performed by Landlord in
accordance with Section 2.A above), including installation of any equipment or
machinery which requires modification of or additions to any existing electrical
outlet or which would increase Tenant's usage of electricity beyond Permitted
Power (all such alterations being referred to collectively as "ALTERATIONS"),
without in each instance first obtaining the written consent of Landlord. As to
any Alterations to which Landlord has consented, Tenant, at its expense, shall
pay all engineering and design costs incurred by Landlord attributable to the
Alterations and obtain all required governmental permits and certificates, and
cause such Alterations to be completed in compliance therewith and all
applicable laws and regulations and all applicable requirements of Landlord's
insurance carriers. All Alterations shall be performed in a good and workmanlike
manner, using new materials and equipment equal or better in quality to the
odginal installations in the Premises. All repair and maintenance work required
to be performed by Tenant pursuant to the provisions of B below, and any
Alterations permitted by Landlord pursuant hereto, shall be done at Tenant's
expense by Landlord's employees or, with Landlord's consent by persons requested
by Tenant and authorized in writing by Landlord; provided, however, if such work
is performed by persons who are not employees of Landlord,

<PAGE>
 
Tenant shall pay to Landlord, upon receipt of billing therefor, the costs for
supervision and control of such persons as Landlord may determine to be
necessary. If Landlord authorizes persons requested by Tenant to perform such
work, prior to the commencement of any such work, Tenant shall on request
deliver to Landlord certificates issued by insurance companies qualified to do
business in Colorado evidencing that workmen's compensation, public liability
insurance and property damage insurance (all in amounts, with companies and on
forms satisfactory to Landlord) are in force and effect and maintained by all
contractors and subcontractors engaged by Tenant to perform such work. All such
policies shall name Landlord (and any Mortgagee) as an additional insured. Each
such certificate shall provide that the same may not be canceled or modified
without 10 days prior written notice to Landlord and such Mortgagee. Further,
Landlord or such Mortgagee shall have the right to post notices in the Premises
in locations which will be visible by parties performing any work on the
Promises stating that Landlord is not responsible for the payment for such work
and setting forth such other information as Landlord may deem necessary.
Alterations, repair and maintenance work shall be performed in a manner which
will not unreasonably interfere with, delay, or impose any additional expense
upon Landlord in the maintenance or operation of the Building or upon other
tenants' use of their premises.

          B.  Tenant shall keep the Premises in as good condition and repair as
when they were entered upon, and in an orderly state, loss by fire or other
casualty or ordinary wear excepted. Subject to Landlord's obligation to make
repairs in the event of certain casualties as set forth in Section 13 , Landlord
shall have no obligation for the repair or replacement of any portion of the
interior of the Premises which is damaged or wears out during the Lease Term
regardless of cause, including, without limitation, carpeting, draperies, window
coverings, interior plate glass, wallcoverings, painting, or any of Tenant's
property or betterments in the Premises.

          C.  All Alterations and permanent fixtures installed in the Premises,
including all partitions, paneling, carpeting, drapes or other window covering,
and light fixtures (but not including movable office furniture not permanently
attached to the Building), shall be deemed a part of the real estate and the
property of Landlord and shall remain upon and be surrendered with the Premises
without disturbance or injury at the end of the Lease Term, unless Landlord
gives Tenant notice not later than 15 days before the end of the Lease Term to
have Tenant remove all or any of the Alterations, and which event Tenant shall
promptly remove at Tenant's expense the Alterations specified by Landlord and
restore the Premises to their prior condition, reasonable wear and tear
excepted.

the Premises free and clear of all mechanics' and other liens on account of work
done for Tenant or persons claiming under it, excluding Tenant Finish Work

the Building or any action affecting the title thereto be commenced as a result
of such work, Tenant shall cause such liens to be removed of record

                                       11
<PAGE>
 
within 5 days after notice from Landlord. If Tenant desires to contest any claim
or lien, Tenant shall furnish to Landlord adequate security of at least 150% of
the amount of the claim, plus estimated costs and interest, or, at Landlord's
option, file a bond and obtain a release of the lien pursuant to applicable law.
If a final judgment establishing the validity or existence of any such lion is
entered, Tenant shall pay and satisfy it at once. If Tenant shall be in default
in paying any charge for which a mechanic's lien or suit to foreclose the lien
has been recorded or filed, and shall not have given Landlord security as
provided above, Landlord may (but without being required) pay such lien or claim
and any costs, and the amount so paid, together with reasonable attorneys' fees
incurred in connection therewith, shall be immediately due from Tenant to
Landlord.

thereof is sublet or occupied by other than Tenant, Landlord may, after default
by Tenant, collect rent from the assignee, subtenant, or occupant, and apply the
net amount collected to the rent and other charges hereunder, but no such
assignment, subletting, occupancy, or collection shall be deemed an acceptance
of the assignee, subtenant, or Occupant as the Tenant hereof, or a release of
Tenant from further performance by Tenant unless expressly agreed to in writing
by Landlord. Consent by Landlord to any one assignment or subletting shall not
be construed as releasing the requirement of obtaining the Landlord's written
consent to any further assignment or subletting rincluding subletting by any
subtenant). Notwithstanding the consent of Landlord to any subletting or
assignment, Tenant shall not be relieved from its primary obligations hereunder
to Landlord including but not limited to the payment of all Base Rent and

such request Tenant shall pay to Landlord within 30 days of receipt of an
invoice therefor all reasonable costs incurred by Landlord in reviewing and
preparing documents with respect to any proposed subletting or assignment of the
Premises.

              C.  In the event Tenant receives rental or other sums from any
subtenant or assignee in excess of the Base Rent and increases in Operating
Expenses required to be paid by Tenant, Landlord shall be entitled to 50% of
such excess. Tenant shall promptly pay to Landlord 50% of such excess rental as
when it is received by Tenant from any such subtenant or assignee.

Tenant, Tenant's agents, servants or employees, or of any other person entering
upon the Premises; under express or implied invitation of Tenant, or where such
injuries are the result of the violation of the provisions of this Lease by any
of such persons.

               A.   Landlord shall maintain property insurance on the shell and
core of the Building and on the Premises, Building and Common Areas to the
extent of the Standard Tenant Finish therein, in such amounts, from such
companies, and on such terms and conditions, including loss of rental insurance,
as Landlord deems appropriate. Landlord will not carry insurance of any kind on
Tenant's furniture and furnishings or an any fixture or equipment removable by

notice to Landlord and any Mortgagee. Tenant shall deliver certificates as
requested by Landlord evidencing that such insurance is in force and effect. The
limits of such insurance shall not, under any circumstances, limit the liability
of Tenant hereunder.

               E.   Notwithstanding anything to the contrary contained herein,
Landlord and Tenant hereby mutually waive and release their respective rights of
recovery against each other for (a) any loss to its property capable of being
insured against by "all risk" insurance coverage whether carried or not; and 

                                       13
<PAGE>
 
(b) all loss, cost, damage or expense arising out of or due to any interruption
of business (regardless of the cause therefor), increased or additional
operating costs or other costs or expenses, whether similar or dissimilar,
which could be insured against under business interruption insurance (whether or
not carried). Each party shall notify their insurers of these mutual waivers,
obtain at its cost waivers of subrogation and any other special endorsements
required by their insurer to evidence compliance with the aforementioned waiver,
and shall upon request provide the other evidence that its policies have been so
endorsed.

 Section 13.   CASUALTY AND RESTORATION OF PREMISES.
               ------------------------------------ 

               A.   If the Premises or the Building are damaged by fire or other
casualty so as to render the Premises wholly untenantable, and if a licensed
architect selected by Landlord shall certify in writing to Landlord and Tenant
within 60 days of the casualty that the Premises cannot, with the exercise of
reasonable diligence, be made fit for occupancy within 180 days from the date
of the casualty, then this Lease shall terminate as of the date of such casualty
and Tenant shall thereupon surrender to Landlord the Premises and all interest
therein, and Landlord may reenter and take possession of the Premises and remove
Tenant therefrom. Tenant shall pay rent, duly apportioned, up to the time of
such termination. If, however, the damage is such that the architect shall
certify within the 60-day period that the Premises can be made tenantable within
the 180-day period, then, except as provided in C below, Landlord shall repair
such damage to the extent of the Standard Tenant Finish with all reasonable
promptness.

               B.   If the Premises, without the fault of Tenant, is slightly
damaged by casualty, but not so as to render them wholly untenantable or to
require a repair period in excess of 180 days, then, Landlord, after receiving
notice in writing of the occurrence of the casualty, shall, except as provided
in C below, cause them to be repaired to the extent of the Standard Tenant
Finish with all reasonable promptness. If the estimated repair period as
established in accordance with the provisions of A above exceeds 180 days, then
the provisions of A shall control even if the Premises are not wholly
untenantable.

               C.   If the Building is materially damaged by casualty so that
the estimated repair period established in accordance with A above exceeds 180
days, or if the damage is material and is not covered by Landlord's casualty
insurance (even if in either instance the Premises may not be affected, or if
affected, can be repaired within the 180 day period), Landlord may, within 60
days of such casualty, in the exercise of its reasonable business judgment,
determine not to reconstruct or rebuild the Building, in which event, upon
notice in writing to that effect given by Landlord to Tenant within the 60-day
period, Tenant shall pay the rent and other charges, properly apportioned up to
the date of notice (or the date of the casualty if the Promises is untenantable
by reason of such casualty), and this Lease shall terminate as of such date.

               D.   Provided that the casualty is not the fault of Tenant,
Tenant's agents, servants or employees, Tenant's rent shall abate during any
such period of repair and restoration in the same proportion that the part of
the Premises rendered untenantable bears to the whole.

 Section 14.   CONDEMNATION.
               ------------

               If all or substantially all of the Premises, or any portion of
the Building and Common Areas which shall render the Premises untenantable,
shall be taken by condemnation or similar proceeding, or shall be conveyed in
lieu thereof, then this Lease, at the option of either Landlord or Tenant
exercised by either party giving notice to the other of such termination within
30 days after such taking or conveyance, shall terminate and the rent shall be
duly

                                       14
<PAGE>
 
apportioned as of the date of such taking or conveyance. Tenant shall surrender
to Landlord the Premises and all interest therein under this Lease, and if
necessary Landlord may reenter and take possession of the Premises or remove
Tenant therefrom. If less than all of the Premises shall be taken by such
proceeding, Landlord shall promptly repair the Premises as nearly as possible
to their immediately prior condition unless Landlord elects not to reconstruct
or rebuild as described in Section 13.C. Landlord shall receive the entire award
or consideration for the portion of the Building so taken in the event of any
such taking or conveyance, provided Tenant shall be entitled to separately claim
for Tenant's trade fixtures and removable personal property.

 Section 15.   DEFAULT.
               ------- 

               A.   Each of the following shall be an "EVENT OF DEFAULT":

                    (1)  Tenant shall fail to pay punctually rent or any other
amounts due hereunder, provided, however, that Tenant may cure an Event of
Default under this provision at any time prior to 5 days after receipt of
written notice thereof from Landlord. Tenant shall not be entitled to more than
2 notices of a monetary default during any Lease Year, and thereafter if any
rent or other amounts owing hereunder are not paid when due, no cure period
shall be allowed under this provision;

                    (2)  Tenant shall abandon the Premises,

                    (3)  This Lease or the interest of Tenant shall be
transferred to or shall pass to any other person or party except in accordance
with Section 10;

                    (4)  This Lease or the Premises (or any part) shall be
taken by execution or other process directed against Tenant, or shall be taken
by any attachment by any creditor of or claimant against Tenant and is not be
discharged or disposed of within 15 days after its levy;

                    (5)  The filing of any petition or the commencement of any
case or proceeding by the Tenant under any provision or chapter of any federal
or state bankruptcy low or any other federal or state law relating to insolvency
or reorganization, the adjudication that the Tenant is insolvent or bankrupt, or
the entry of an order for relief under any federal or state bankruptcy law with
respect to Tenant.

                    (6)  The filing of any petition or the commencement of any
case or proceeding described in (5) above against the Tenant, unless such
petition and all related proceedings are dismissed within 60 days from the
filing, the filing of an answer by Tenant admitting the allegations of any such
petition, or the appointment of or taking possession by a custodian, trustee or
receiver for all or any assets of the Tenant, unless such appointment is vacated
or dismissed within 60 days from the date of such appointment;

                    (7)  The insolvency of the Tenant or the execution by the
Tenant of an assignment for the benefit of creditors, the convening by Tenant of
a meeting of its creditors, or any class thereof, for purposes of effecting a
moratorium upon or extension or composition of its debts, or the failure of the
Tenant generally to pay its debts as they mature;

                    (8)  The admission in writing by Tenant or if Tenant is a
partnership any partner of Tenant that Tenant is unable to pay its debts as they
mature or it is generally not paying its debts as they mature;

                    (9)  Tenant shall fail to take possession of the Premises on
the date the Lease Term commences,

                    (10) Tenant shall fail to perform any of the other provision
of this Lease 

                                       15
<PAGE>
 
on Tenant's part to be performed, and such failure shall continue for a period
of 30 days after written notice to Tenant, or if such failure cannot be
reasonably be cured within the 30-day period but can be had within 75 days or
less, Tenant shall not in good faith have commenced such cure within such 30-day
period and shall not diligently proceed to completion.

               B.   Upon any one or more Events of Default, then Landlord shall
at its election have the right, then or at any time thereafter, either:

               (1)  (a)  To reenter and take possession of the Premises (or any
part) without demand or notice, and repossess them and expel Tenant and those
claiming through or under Tenant and remove the effects of both or either, using
such force as may be necessary, without being liable for the prosecution
thereof, or being deemed guilty of trespass and without prejudice to any
remedies. Should Landlord elect to reenter as provided herein, or should
Landlord take possession pursuant to legal proceedings or pursuant to any notice
provided for by law, Landlord may, from time to me, without terminating this
Lease, relet the Premises (or any part), either alone or in conjunction with
other portions of the Building, in Landlord's or Tenant's name, but for the
account of Tenant, for such term or term (which may be greater or less than the
perioi which would otherwise have constitked the balance of the Lease Term) and
on such conditions and upon such other term (which may include such concessions,
free rent, alterations, and repair of the Premises) as Landlord, in its sole
discretion, nay determine, and Landlord may collect and receive the rents
therefor. Landlord shall not be responsible or liable for any failure to relet
the Premises, or any part thereof, or for any failure to collect any rent due
upon such reletting. No reentry or taking possession of the Premises by Landlord
shall be construed as an election on Landlord's part to terminate this Lease
unless written notice of such intention is given to Tenant and no notice from
Landlord hereunder or under a forcible entry and detainer statute or similar law
shall constitute an election by Landlord to terminate this Lease unless the
notice specifically so states. Landlord reserves the right following any reentry
and/or reletting to exercise its right to terminate this Lease by giving Tenant
such written notice, in which event the Lease will terminate as specified in the
notice.

               (b)  If Landlord elects to take possession of the Premises as
provided herein without terminating the Lease, Tenant shall pay to Landlord (i)
the rent and other sums which would be payable hereunder if such repossession
had not occurred, less (ii) the net proceeds, if any, of any reletting of the
Premises after deducting all of Landlord's expenses incurred in connection with
such reletting, including, without limitation, all repossession costs, brokerage
commissions, legal expenses, attorneys' fees, alteration, remodeling and repair
costs, tenant finish costs, and expenses of preparation for such reletting. If,
in connection with any reletting, the now lease term extends beyond the existing
Lease Term, or the premises covered thereby include other premises not part of
the Premises, a fair apportionment of the rent received from such reletting and
the expenses incurred in connection therewith, as provided above, will be made
in determining the net proceeds received from reletting within such
determination, any rent concessions will be apportioned over the term of the new
Lease. Tenant shall pay such amounts to Landlord monthly on the days on which
the rent and other amounts owing hereunder would have been payable if possession
had not been retaken and Landlord shall be entitled to receive them from Tenant
on each such day;

               (2)  To give Tenant written notice of intention to terminate this
Lease as of the date of such notice or an any later date specified therein, and
on such date, Tenant's right to possession of the Premises shall cease and the
Lease shall terminate, except as to Tenant's liability as provided below, as if
the expiration date specified in such notice was the date otherwise fixed as
the end of the Lease 

                                       16
<PAGE>
 
Term. If this Lease is terminated pursuant to the provisions of this (2), Tenant
shall remain liable to Landlord for damages in an amount equal to the rent and
other sums which would have been owing by Tenant hereunder for the balance of
the Lease Term had it not been terminated, less the net proceeds (if any) of any
reletting of the Premises by Landlord subsequent to such termination, after
deducting all Landlord's expenses in connection with such reletting, including,
without limitation, the expenses enumerated in (1)(b). Landlord shall be
entitled to collect these damages from Tenant monthly on the days on which the
rent and other amounts would have been payable hereunder if this Lease had not
been terminated, and Landlord shall be entitled to receive these from Tenant on
each such day. Alternatively, at the option of Landlord, in the event this Lease
is terminated, Landlord shall be entitled to recover forthwith against Tenant,
as damages for loss of bargain and not as a penalty, an amount equal to the
worth at the time of termination of the excess, if any, of the amount of rent
reserved and payable under this Lease for the balance of the Lease Term hereof
over the amount of rental which Landlord can obtain as rent for the remaining
balance of the term ("REASONABLE RENTAL VALUE"), plus all amounts incurred by
Landlord in obtaining possession of and reletting the Premises including but
not limited to attorneys' fees, reletting expenses, alterations and repair
costs, and brokerage commissions), plus all amounts for unamortized Standard
Tenant Finish costs which have not yet been recovered through rental payments.

               (3)  In addition to Landlord's rights set forth in (1) and (2)
above, if Tenant fails to pay rent and other amounts owing hereunder as and when
due more than two times during any 12-month period during the Lease Term, then,
upon the occurrence of the third or any subsequent failure to pay during that 
12-month period, Landlord, at its sole option, shall have the right to require
that Tenant, as a condition precedent to curing such default, pay to Landlord,
in cash or its equivalent, in advance, the entire rent and Landlord's estimate
of all other amounts which will become due and owing hereunder by Tenant for the
balance of the Lease Term (or if such default occurs during any extension term,
the amounts which will be required to be paid will be those attributable to the
balance of the extension term). All such amounts shall be paid by Tenant within
30 days after demand from Landlord. All monies so paid shall be retained by
Landlord, without interest, for the balance of the Lease Term, and shall be
applied by Landlord to all amounts owing hereunder by Tenant as they become due
Of Landlord's estimate of the amounts for which Tenant is responsible hereunder
are inaccurate, when such error is discovered Landlord shall pay to Tenant, or
Tenant shall pay to Landlord, within 30 days after written notice, of the excess
or deficiency, as the case may be, which is required to reconcile the amount on
deposit with Landlord with the actual amount for which Tenant is responsible).

               C.   Action(s) to recover rent, other amounts, and damages set
forth above may be brought by Landlord, from time to time, at Landlord's
election, and nothing shall be deemed to require Landlord io await the date on
which the Lease Term would have otherwise expired had there been no such default
or termination. Landlord agrees to use reasonable efforts, subject to the
exercise of its reasonable business judgment, to relet the premises to a
qualified tenant(s) should it retake possession pursuant to B.(1) or (2) above,
recognizing, however, that Landlord for its affiliates) is the owner or operator
of other buildings and is not obligated in any way to give any preference to
such reletting over leasing in such other buildings. Each right and remedy
provided in this Lease shall be cumulative and in addition to, and not in lieu
of, every other right or remedy provided in this Lease or now or hereafter
existing by statute or otherwise, including suits for injunctive relief or
specific performance. The exercise by Landlord of any one or more of the fights
or remedies provided in this Lease or now or hereafter existing by statute or
otherwise shall not preclude the simultaneous or later exercise by Landlord of

                                       17
<PAGE>
 
any or all other rights or remedies provided in this Lease or now or hereafter
existing by statute or otherwise. If any action is commenced arising out of the
terms and provisions of this Lease, the prevailing party shall be entitled to
recover from the other party all costs and expenses, including without
limitation all reasonable attorneys' fees, incurred in connection with that
action.

               D.   No failure by Landlord to insist upon the strict performance
of any provision of, or the exercise of any right or remedy upon a breach of
this Lease, and no acceptance of full or partial rent during the continuance of
any such breach, shall constitute a waiver of any such provision. No provision
to be performed or complied with by Tenant and no breach thereof shall be
waived, altered, or modified except by written instrument signed by Landlord. No
waiver of any breach shall affect or after this Lease. Notwithstanding any
termination of this Lease, any provisions which by their nature require
observance or performance by Landlord or Tenant subsequent to such termination
shall continue in force and affect.

               E.   Nothing contained in this Section 15 shall limit or
prejudice the right of Landlord to liquidated damages in any bankruptcy,
insolvency, receivership, reorganization, or dissolution proceeding in an amount
equal to the maximum allowed by any statute or rule of law governing such
proceeding, whether or not such amount be greater, equal to or less than the
amounts recoverable, either as damages or rent, under any of the preceding
provisions of this Lease. Any such proceeding or action involving bankruptcy,
insolvency, reorganization, arrangement, assignment for the benefit of
creditors, or appointment of a receiver or trustee, as set forth above, shall be
considered an Event of Default only when it shall be taken or brought by or
against the then holder of the leasehold estate under this Lease. Landlord shall
be entitled under the federal bankruptcy law to "adequate assurance" of future
performance of the terms and provisions of this Lease in the event of an
assumption or assignment in bankruptcy, and the parties agree that the term
"adequate assurance" shall include at few the following: (i) The financial
condition and resources of Tenant were a material inducement to Landlord in
entering into this Lease, and to assure that the proposed assignee will have the
resources to pay the rent under this Lease, any proposed assignee must have a
net worth (as defined in accordance with generally accepted accounting
principles consistently applied) at least as great as the net worth of Tenant on
the date this Lease became effective increased by 7%, compounded annually, for
each year from the Lease Commencement Date through the date of the proposed
assignment; (ii) Any proposed assignee of this Lease must assume and agree to be
personally bound by the terms, provisions, and covenants of this Lease.

               F.   Any rents or other amounts owing hereunder not paid within 5
days after the date they are due or any amounts advanced by Landlord on behalf
of Tenant shall thereafter bear interest at an annual rate of three percentage
points over the prime rate then being charged by First Interstate Bank of
Denver, N.A. to its most creditworthy customers on an unsecured basis for short
term loans (the "PRIME RATE"), or the highest rate permitted by applicable usury
law, whichever is lower, until paid. Further, in the event any rents or other
amounts owing hereunder are not paid within 5 days after written notice,
Landlord will incur additional administrative expenses, the amount of which will
be difficult if not impossible to determine; accordingly, Tenant shall pay to
Landlord an additional one-time late charge for any such late payment in the
amount of 5% of such payment.

               G.   In the event of any alleged default on the part of Landlord,
Tenant shall give written notice to Landlord in the manner herein set forth and
shall afford Landlord a reasonable opportunity to cure any such default (which
shall not be less than 30 days). Notice to Landlord of any such alleged default
shall be 

                                       18
<PAGE>
 
ineffective unless such notice is simultaneously delivered to any holder of a
mortgage and/or deed of trust affecting all or any portion of the Building
("MORTGAGEES"); Tenant agrees to give all Mortgagees, by certified mail, return
receipt requested, a copy of any notice of default served upon Landlord,
provided that prior to such notice Tenant has been notified in writing (by way
of notice of assignment of rents and Leases, or otherwise), of the address of
such Mortgagees. Tenant further agrees that if Landlord shall have failed to
cure such default within the time provided for in this Lease, then the
Mortgagees shall have an additional 30 days within which to cure such default,
or if such default cannot be cured within that time, then such additional time
as may be necessary if, within such 30 days, any Mortgagee has commenced and is
diligently pursuing the remedies necessary to cure such default (including
commencement of foreclosure proceedings if necessary to effect such cure), in
which event this Lease shall not be terminated while such remedies are being
diligently pursued. In no event will Landlord or any Mortgagee be responsible
for any consequential damages incurred by Tenant as a result of any default,
including but not limited to lost profits or interruption of business at a
result of any alleged default by Landlord hereunder.

 Section 16.   SURRENDER.
               --------- 

               A.   Upon expiration or other termination of the Lease Term,
Tenant shall promptly quit and surrender to Landlord the Premises broom clean,
in good order and condition, ordinary wear and tear and loss by fire or other
casualty excepted unless due to the negligence of Tenant, and Tenant shall
remove all of its movable furniture and other effects and such Alterations as
Landlord shall have required Tenant to remove pursuant to Section 8.C. If Tenant
fails to so vacate the Promises, Tenant shall be responsible to Landlord for all
costs incurred by Landlord as a result of such failure, including amounts
required to be paid to third parties who were to have occupied the Premises.

               B.   All movable furniture and personal effects of Tenant not
removed from the Premises upon their abandonment or upon termination of this
Lease shall conclusively be deemed to have been abandoned and may be
appropriated, sold, stored, destroyed, or otherwise disposed of by Landlord
without notice to Tenant or any other person, and without obligation to account
therefor, and Tenant shall pay Landlord all expenses incurred in connection with
the storage and/or disposition of such property.

               C.   If, after the expiration of this Lease, Tenant shall without
any express written agreement remain in possession of the Premises and continue
to pay rent then such holding-over shall be deemed to be a holding upon a
tenancy from month-to-month, subject to all the terms and conditions hereof on
the part of Tenant to be observed and performed, at a monthly rent equivalent to
150% of the monthly installment paid by Tenant immediately prior to such
expiration or the then current market rental rate, whichever is greater. All
such rent shall be payable in advance on the same day of each calendar month.
Such month-to-month tenancy may be terminated by either party upon 10 days
notice prior to the end of any such monthly period. Nothing contained herein
shall be construed as obligating Landlord to accept any rental tendered by
Tenant after the expiration of the Lease Term or, if so accepted, as relieving
Tenant of its liability and obligations pursuant to this Section.

               D.   No monetary payments by Tenant to Landlord after the
termination of this Lease or after giving of any notice (other than a demand for
payment of money) by Landlord to Tenant, shall reinstate, continue or extend the
Lease Term or affect any notice given to Tenant before the payment of such
money, it being agreed that after the service of notice, the commencement of
suit, or final judgment granting Landlord possession of the Premises, Landlord
may receive and collect any rent, or any other sums of money due under this
Lease, or otherwise exercise Landlord's rights and 

                                       19
<PAGE>
 
remedies, and the payment of such sums, whether as rent or otherwise, shall not
waive the notice or affect any pending suit or judgment obtained.

 Section 17.   SUBORDINATION AND ATTORNMENT.
               ---------------------------- 

               A.   At Landlord's option, this Lease shall be subordinate to any
present or future mortgage or dead of trust encumbering the Building, including
any amendment, modification, or restatement, and to any and all advances made
under any such mortgage or deed of trust. Tenant agrees that with respect to any
of the foregoing, no documentation, other than this Lease, shall be required to
evidence such subordination.

               B.   If any holder of such mortgage or deed of trust shall elect
to have this Lease superior to the lien of the holder's mortgage or deed of
trust, and shall give written notice to Tenant, this Lease shall be deemed prior
to such mortgage or deed of trust, whether this Lease is dated prior or
subsequent to the date of such mortgage or deed of trust, or its recording date.

               C.   In confirmation of such subordination or superior position,
as the case may be, Tenant shall execute such documents as may be required by
Landlord or its mortgagee to evidence the subordination of its interest herein
to any of the documents described above, or to make this Lease prior to the lien
of any mortgage or deed of trust, and failing to do so within 10 days after
written demand, Tenant hereby irrevocably appoints Landlord as Tenant's 
attorney-in-fact and in Tenant's name, place and stead, to execute such
documents.

               D.   Tenant agrees to attorn to all successor owners of the
Building whether or not such ownership is acquired as a result of a sale,
foreclosure, or otherwise.

 Section 18.   ESTOPPEL. Tenant agrees at any time and from time to time, upon
               --------
not less than 10 days prior written request by Landlord, to execute, acknowledge
and deliver to Landlord a statement in writing certifying that this Lease is
unmodified and in full force and effect (or if there have been modifications,
that the same is in full force and effect is modified, and stating the
modifications), that there have been no defaults thereunder by Landlord or
Tenant (or if there have been defaults, setting forth the nature thereof), the
date to which the rent and other charges have been paid in advance, if any, and
such other information as Landlord may request. It is intended that any such
statement may be relied upon by a prospective purchaser of all or any portion of
Landlord's interest herein or a holder of any mortgage or deed of trust
encumbering the Building. Tenant's failure to deliver such statement within such
time shall be conclusive upon Tenant that (i) this Lease is in full force and
effect, without modification except as may be represented by Landlord; (ii)
there are no uncured defaults in Landlord's performance; and (iii) not more that
1 months rent has been paid in advance. Tenant shall also provide such other
information as Landlord may reasonably require from time to time and, upon
request, deliver to Landlord a corporate or partnership resolution, as the case
may be, certifying that the party signing the statement of Tenant is properly
authorized to do so.

                                       20
<PAGE>
 
 Section 19.   ENVIRONMENTAL.
               ------------- 

               A.   Attached as EXHIBIT B is a report (the "ENVIRONMENTAL
REPORT") prepared by a consultant reporting on Hazardous Substances (if any) at
the Premises and/or Building. Tenant has reviewed the Environmental Report, has
no objection to it, and accepts the Premises subject to any items noted in the
Environmental Report. Landlord represents and warrants that to its knowledge it
knows of no violation at the Building relating to Hazardous Substances other
than as stated in the Environmental Report.

               B.   Tenant shall: generate and store Hazardous Substances at the
Premises only in amounts as are incident to and necessary for the normal
operation of Tenant as permitted by this Lease; comply with all obligations
imposed by applicable law, rules, regulations, or requirements regarding such
generation and storage of Hazardous Substances, prohibit any generation,
storage, or disposal of Hazardous Substances at the Premises except as permitted
above; promptly deliver to Landlord complete copies of all notices received by
Tenant from any governmental authority with respect to the generation, storage
or disposal by Tenant of Hazardous Substances; promptly notify Landlord of any
spills or accidents involving a Hazardous Substance; and permit reasonable entry
to the Premises by Landlord for verification of Tenant's compliance with these
provisions. Tenant shall install and maintain a self-contained system for
collecting, retaining and disposing of Hazardous Substances and shall not allow
any Hazardous Substances to enter subsurface soils or to be discharged into any
sanitary or storm sewer system. Tenant agrees to utilize only transporters
approved by the Environmental Protection Agency and State of Colorado to deliver
to and remove Hazardous Substances from the Premises. Tenant shall indemnify and
defend Landlord with legal counsel reasonably acceptable to Landlord) from and
against any costs, fees or expenses including, without limitation, clean-up
expenses, third party claims and environmental impairment expenses, and
reasonable attorneys' fees and expenses) incurred by Landlord in connection with
Tenant's generation, storage or disposal of Hazardous Substances. This
indemnification by Tenant shall survive the termination or expiration of this
Lease.

               C.   On or before 10 days before the expiration date of the Lease
Term, Tenant shall, at its sole cost and expense, update the Environmental
Report, using the consultant who initially prepared the report or another
licensed consultant reasonably acceptable to Landlord, to determine the
environmental status of the Premises as of the date of that update. To the
extent the update or any inspection by Landlord prior Tenant's delivery of the
Premises to Landlord shows that Tenant has generated, stored or disposed of
Hazardous Substances contrary to the provisions of this Lease, Tenant shall
immediately, at its sole expense, commence and pursue to completion a
remediation program as to such Hazardous Substances and shall, to Landlord's
reasonable satisfaction, bring the Premises into an environmental condition
equal or better than the condition disclosed under the initial Environmental
Report described in A above. If Tenant fails to comply with the provisions of
this Section prior to the expiration or earlier termination of the Lease Term,
or prior to Tenant's vacating the Premises, then Landlord, in addition to
Landlord's right to utilize all or any portion of any security deposit to
satisfy Tenant's obligations hereunder, shall have the option of either
considering this Lease as having ended or treating Tenant as a holdover Tenant

amounts owing hereunder if Landlord fails to perform its obligations set forth

commence a separate action against Landlord for any violation by Landlord of the
provisions hereof so long as notice is first given to Landlord and any Mortgagee
and an opportunity granted to Landlord and such holder to correct such violation
as provided in Section 15.G. If any provision of this Lease is illegal, invalid,
or unenforceable under present or future laws effective during the Lease Term,
it is the intention of the parties that the remainder of this Lease shall not be
affected and that in lieu of each provision of this Lease that is illegal,
invalid, or unenforceable, there shall be added as a part of this Lease a
provision as similar to such illegal, invalid, or unenforceable provision as may
be possible and be legal, valid, and enforceable.

               D.   The captions to this Lease are added as a convenience and
have no legal significance.

               E.   Except as otherwise specifically set forth in this Lease,

counsel to that effect.

               G.   Nothing done by Landlord or Landlord's agents during the
term hereof, including without limitation any agreement to accept surrender of
the Premises or to amend or modify this Lease, shall be deemed to be binding on
Landlord unless agreed to by a partner or officer of Landlord, as the case may
be, or a party designated in writing by Landlord as so authorized to act. The

rent and all other amounts owing as herein stipulated shall he deemed to be
other than on account of the earliest stipulated rent or other amounts. No

Landlord and Tenant shall execute an amendment to the Lease which incorporates
such modifications, additions and adjustments to Tenant's Pro Rata Share, if
necessary. Tenant shall not use the name and/or mark "Inverness,"

               I.   Tenant agrees that no diminution of light, air or view by
any structure that may hereafter be erected (whether or not by Landlord) shall
entitle Tenant to any reduction of rent or other charges under this Lease,

Lease or Tenant's obligations.

               J.   So long as Tenant complies with the provisions hereof

shall be subject to binding arbitration between the parties in accordance with
the commercial arbitration rules of the American Arbitration Association, with
any such controversies being submitted to a panel of three arbitrators selected
from the panels of arbitrators of the American Arbitration Association. However,
the issue of possession shall not be subject to either jury trial or
arbitration.

receipt of Landlord notice of such exercise to Landlord under the terms,

exercises the Option, the Lease shall be deemed extended and thereafter the
parties shall execute amendment to the Lease setting forth the terms of the
extension.

               C.   Unless Landlord is timely notified by Tenant in accordance
with subparagraphs A and B above, it shall be conclusively deemed that Tenant
does not desire to exercise the Option, and the Lease shall expire in
accordance with its terms, at the end of the Primary Lease Term.

               D.   Tenant shall not be in default under the Lease at the time
of exercise of the Option or at the time of the commencement of the Option Term.

rental rate be less than the rent which Tenant is paying immediately prior to
the commencement of the Option Term. Such terms and conditions may include, 
among other things, net rent escalations, passthroughs and other matters then
included in Landlord's standard lease form for the Building which it uses for
the leasing of space to third parties.

ARTICLE TWO:  LEASE AND LEASE TERM

2.01  LEASE OF PROPERTY.  Landlord hereby leases the Property to Tenant and
Tenant hereby leases the Property from Landlord for the Lease Term stated in
Section 1.05.  As used herein, the "Commencement Date" shall be the date
specified in Section 1.05 for the beginning of the Lease Term.

2.02  EARLY OCCUPANCY.  If Tenant occupies the Property prior to the

earlier termination of this Lease.  Tenant shall reimburse Landlord for and

<PAGE>
 
all damages incurred by Landlord from any delay by Tenant in vacating the
Property. If Tenant does not vacate the Property upon the expiration or earlier
termination of this Lease, Tenant's occupancy of the Property shall be a "month-
to-month" tenancy, subject to all the terms and provisions applicable to a 
month-to-month tenancy, except that the rent then in effect shall be increased 
by fifty percent (50%).

ARTICLE THREE:  RENT AND SECURITY DEPOSIT

3.01  RENT.  Tenant agrees to pay rent for the Property at the rate specified in

the party designated in Section 1.11 at the address stated herein for such
party.

days after its due date, Tenant shall pay the party named in Section 1.11 above
a late charge equal to the sum stated in Section 1.12 above for each day from
its due date until such delinquent sum is received.  The parties agree that such
late charge represents a fair and reasonable estimate of the costs Landlord will
incur by reason of such late payment.

3.03  SECURITY DEPOSIT.  Upon execution hereof, Tenant shall deposit with the
party named in Section 1.11 above a cash Security Deposit in the sum stated in
Section 1.07.  Landlord may apply all or part of the Security Deposit to any

hazardous or toxic substances to be placed on the premises without prior written
permission from the Landlord.  Hazardous or toxic substances as referred to in
this paragraph shall be defined by U.S. Environmental Protection Agency

not limited to the roof or exterior walls of the building or other improvements

any damage and close any holes caused or revealed by such removal.

right, during normal business hours, to enter the Property and any buildings and
other improvements thereon to view, inspect, repair or show the Property.
Landlord shall attempt to advise tenant of the intent of Landlord or its
authorized agents to enter the property.

4.06  INTERRUPTION OF SERVICE.  Interruption or curtailment of services
furnished to the Property, if caused by strikes, mechanical difficulties, or any
cause beyond Landlord's control, whether similar or dissimilar to those
enumerated, shall not entitle Tenant to any claim against Landlord or to nay
abatement in rent, nor shall the same constitute constructive or partial
eviction, unless Landlord fails to take such measures as may be reasonable in
the circumstances to restore the service without undue delay.  If the premises
are rendered untenantable in whole or in part for fifteen (15) business days
because of such interruption or curtailment of services (other than caused by
any act or omission of Tenant or its invitees, employees or customers), there
shall be a proportionate abatement of rent during the period of such
untenantability.

4.07  EXEMPTIONS FROM LIABILITY.  Landlord shall not be liable for any damage or
injury to the person, business (or any loss of income therefrom), goods, wares,
merchandise or other property of Tenant, Tenant's employees, invitees, customers
or any other person in or about the Property, whether such damage or injury is
caused by or results from:  (a) fire, steam, electricity, water, gas, or rain;
(b) the breakage, leakage, obstruction or other defects of pipes, sprinklers,
wires, appliances, plumbing, air conditioning or lighting fixtures or any other
cause; (c) conditions arising on or about the Property or upon other portions of
any building of which the Property is a part, or from other sources or places;
or (d) any act or omission of any other tenant of any building of which the
Property is a part.  Landlord shall not be liable for any such damage or injury
even though the cause of or the means of repairing such damage or injury are not
accessible to Tenant.  The provisions of this Section 4.07 shall not, however,
exempt Landlord from liability or Landlord's gross negligence or willful
misconduct.

ARTICLE FIVE:  MAINTENANCE, REPAIRS AND ALTERATIONS

5.01  ACCEPTANCE OF PREMISES.  Tenant acknowledges that Tenant has fully
inspected the Property.  Tenant hereby accepts the Property and the buildings
and improvements situated thereon, as suitable for the purpose for which the
same are leased, in their present condition (including all latent or
environmental defects or risks), with such changes therein as may be caused by
reasonable deterioration between the date hereof and the Commencement Date;
provided that Tenant shall not be responsible for remedying any such latent or
environmental defects or risks unless it becomes necessary to remedy such
defects or risks because of alterations, additions or improvements to the
Property made by Tenant, and that Landlord agrees to (a) repair promptly any

except for those repairs and alterations required solely because of the nature
of Tenant's business.  Landlord expressly disclaims and Tenant waives any and
all warranties (including the warranty of suitability), representations and
obligations of Landlord or Landlord's agents that are not expressly stated
herein.  Landlord and Tenant acknowledge that Principal Realtor and cooperating
Realtor have no expertise in the detection or correction of environmentally
hazardous or undesirable items.  Expert inspections are necessary.  Current or
future laws may require clean up by past, current and/or future owners and/or
tenants of the Property.  It is the responsibility of Landlord and Tenant to
retain qualified experts to detect and correct such matters.  Landlord and
Tenant acknowledge that neither Principal Realtor, nor Cooperating Realtor, have
made an independent investigation or determination with respect to the existence
of hazardous substances and environmental conditions in, on or about the
Property.  Any such investigation or determination shall be the responsibility
of Landlord and Tenant.  The Principal Realtor or Cooperating Realtor shall not
be responsible for such an investigation.  Landlord and Tenant shall, jointly
and severally, defend, indemnify and hold harmless Principal Realtor and
Cooperating Realtor from and against all claims, costs, expenses, actions,
losses, damages and liabilities of any kind whatsoever (including reasonable
attorney's fees) directly or indirectly arising out of the existence of
hazardous substances and/or environmental conditions in, on or about the
Property.  This indemnification shall survive the termination of this Lease.

5.02  MAINTENANCE AND REPAIRS BY LANDLORD.  Landlord shall at his expense
maintain only the roof, foundation, underground pipes, all outside plumbing and
the structural soundness of the exterior walls (excluding all windows, window
glass, plate glass, and all doors) of the improvements on the Property in good
repair and condition, except for reasonable wear and tear and any damage caused
by the act or omission of Tenant, or Tenant's invitees, employees or customers.
Tenant shall give immediate written notice to Landlord of the need for repairs
or corrections and Landlord shall proceed promptly to make such repairs.

5.03  MAINTENANCE AND REPAIRS BY TENANT.  Tenant shall at his expense and risk
maintain all other parts of the improvements on the Property in good repair and
condition, including but not limited to repairs (including necessary
replacement) to the interior plumbing, windows, window glass, plate glass,
doors, heating system, air conditioning equipment, fire protection sprinkler
system, elevators and the interior of the said improvements in general; and

                                       5
<PAGE>
 
including the reasonable care of landscaping and regular mowing of the grass,
and maintenance of the paving outside of the improvements and any railroad
siding.  In the event Tenant should neglect reasonably to maintain the demised
premises, Landlord shall have the right (but not the obligation) to cause
repairs or corrections to be made and any reasonable costs therefor shall be
payable by Tenant to Landlord as additional rental on the next rental payment
due date.  Upon termination of this Lease, Tenant shall deliver up the Property
in good repair and condition, reasonable wear and tear, and damage by fire, wind
storm or other causally excepted.  Tenant shall repair any damage caused by
Tenant's act or omission, or the act or omission of Tenant's invitees, employees
or customers.

5.04  ALTERATIONS.  Tenant shall not create any openings in the roof or exterior
wall, or make any alterations, additions or improvements to the Property without

additions or improvements shall not be unreasonably withheld by Landlord.

trade fixtures, provided that Tenant complies with all applicable governmental
laws, ordinances and regulations.  At the expiration or termination of this
Lease, Tenant shall, subject to the restrictions of Section 5.05 below, have the
right to remove such items so installed by it, provided Tenant is not in default
at the time of such removal and provided further that Tenant shall, at the time
of removal of such items, repair in a good and workmanlike manner any damage
caused by installation or removal thereof and restore the premises to the
condition that existed prior to the installation of such items, reasonable wear
and tear excepted.  Tenant shall pay for all costs incurred or arising out of
alterations, additions or improvements in or to the Property and shall not
permit a mechanic's or materialman's lien to be asserted against the Property.

5.05  CONDITION UPON TERMINATION.  Upon termination of this Lease, Tenant shall
surrender the Property to Landlord, broom clean and in the same condition as
received except for ordinary wear and tear which Tenant was not otherwise
obligated to remedy under any provision of this Lease.  However, Tenant shall
not be obligated to repair any damage which Landlord is required to repair under
Article Five.  In addition, Landlord may require Tenant to remove any
alterations, additions or improvements made during the term of this Lease,
whether or not made with Landlord's consent.  In no event, however, shall Tenant
remove any of the following materials or equipment without Landlord's prior
written consent:  any power wiring or power panels; lighting or lighting
fixtures; wall coverings; drapes, blinds or other window coverings; carpets or
other floor coverings; heaters; air conditioners or any other heating or air

6.01  PROPERTY INSURANCE.  Tenant shall not keep anything upon the Property, or
do anything in or about Property except the usage specified herein, which will
increase the rates for fire and standard extended coverage insurance upon the
building or buildings which are part of the Property.  Tenant agrees to pay on
demand any increase in insurance premiums that may be charged to Landlord during
the term of this Lease resulting from a deviation from the usage 

                                       6
<PAGE>
 
specified herein or from any other cause within Tenant's control. Tenant shall
be responsible for maintaining insurance on Tenant's equipment and other
personal property located on the Property.

6.02  LIABILITY INSURANCE.  During the Lease Term, Tenant shall maintain a
policy of comprehensive public liability insurance, at Tenant's expense,
insuring Landing against liability arising out of the ownership, use occupancy
or maintenance of the Property.  The initial amount of such insurance shall be
at least $1,000,000.  Such policy shall contain a provision which prohibits
cancellation or modification of the policy except upon thirty (30) days prior
written notice to Landlord.  Tenant shall deliver a copy of such policy or
certificate (or a renewal thereof) to Landlord prior to the Commercial Date and
prior to the expiration of any such policy during the Lease Term.  If Tenant
fails to maintain such policy, Landlord may elect to maintain such insurance at
Tenant's expense.

6.03  INDEMNITY.  Tenant hereby agrees to indemnify and hold Landlord harmless
from any loss, expense or claims arising out of any injury to persons or damage
to property on or about the Property or any adjacent area owned by Landlord
caused by the negligence or misconduct of Tenant, its employees, subtenants,
licensees or concessionaires or any  other person entering the Property under
express or implied invitation of Tenant, or arising out of the use of the
Property by Tenant and the conduct of its business therein, or arising out of
any breach or default by Tenant in the performance of its obligations hereunder.
Tenant shall not be liable for any injury or damage caused by the negligence or
misconduct of Landlord, or its employees or agents, and Landlord agrees to
indemnify Tenant and hold it harmless from any loss, expense or damage arising
out of such damage or injury.

6.04  WAIVER OF SUBROGATION.  Landlord and Tenant each hereby waive any and all
rights of recovery against the other, or against the officers, employees, agents
or representatives of the other, for loss of or damage to its property, or the
property of others under its control, if such loss or damage is covered by any
insurance policy in force (whether or not described in this Lease) at the time
of such loss or damage; provided however such waiver is made only on the
condition that it does not adversely affect the right of the insured to recover
under the applicable insurance policy or policies.


ARTICLE SEVEN:  ASSIGNMENT AND SUBLETTING

Tenant shall not assign this agreement or sublet the premises, or any part
thereof without the consent of the Landlord in writing, which consent Landlord
agrees it will unreasonably withhold, but no assignment or subletting shall
release Tenant from any obligation hereunder.

ARTICLE EIGHT:  DAMAGE OR DESTRUCTION

8.01  PARTIAL DAMAGE.  In the event the improvements situated on the Property
are partial damaged, or rendered partially unfit for occupancy, by fire or other
casualty, Tenant shall give immediate written notice thereof to Landlord.  If
Landlord's insurance proceeds are sufficient to 

                                       7
<PAGE>
 
pay for the necessary repairs, and if the repairs can reasonably be made within
90 days after the Landlord receives such written notice from Tenant, Landlord
shall forthwith cause such repairs to be made and this Lease shall not
terminate. While such repairs are being made, Landlord shall allow Tenant a fair
reduction in rent in proportion to the extent the improvements are partially
unfit for occupancy, unless such damage, or unfitness for occupancy, is due to
the act or omission of Tenant or Tenant's employees, invitees or licensees.

8.02  UNINSURED PARTIAL DAMAGE OR TOTAL SUBSTANTIAL DESTRUCTION.  In the event
of total or substantial destruction of the improvements situated on the Property
by fire or other casualty, Tenant shall give immediate written notice thereof to
Landlord.  If Landlord's insurance proceeds are insufficient to pay for the
necessary repairs or restoration, or the repairs or restoration cannot
reasonably be made within 90 days after Landlord receives such written notice
from Tenant, this Lease shall terminate and the rent shall be paid to the date
of such casualty.  However, if such damage or destruction is due to the act or
omission of Tenant or Tenant's employees, invitees or licensees, Tenant shall
pay to Landlord, within 60 days after the occurrence of such casualty, any
portion of the anticipated cost of repairing or restoring the improvements to
the same condition as on the date of this Lease that are not reimbursed to
Landlord by insurance proceeds.  Such anticipated cost shall be determined by
Landlord.  Tenant shall make such payment to Landlord, whether or not Landlord
repairs or restores the improvements.

ARTICLE NINE:  DEFAULT AND REMEDIES

9.01  DEFAULT.  The following events shall be deemed to be events of default
under this Lease:

      a.  Failure of Tenant to pay any installment of the rent or other sum
payable to Landlord hereunder on the date that same is due and such failure
shall continue for a period of five (5) days after written notice thereof to
tenant;

      b.  Failure of Tenant to comply with any term, condition or covenant of
this Lease, other than the payment of rent or other sum of money, and such
failure shall not be cured within thirty (30) days after written notice thereof
to Tenant;

      c.  Tenant shall make an assignment for the benefit of creditors;

      d.  Abandonment by Tenant of any substantial portion of the Property or
cessation of the use of the use of the Property for the purpose leased for a
period of more than thirty (30) consecutive calendar days.

9.02  REMEDIES.  Upon the occurrence of any of the events of default listed in
Section 9.01, Landlord shall have the option to pursue any one or more of the
following remedies without any notice or demand whatsoever:

                                       8
<PAGE>
 
a.  Terminate this Lease, in which event Tenant shall immediately surrender the
Property to Landlord.  If Tenant fails to so surrender such premises, Landlord
may, without prejudice to any other remedy which it may have for possession of
the Property or arranges in rent, enter upon and take possession of the Property
and expel or remove Tenant any other person who may be occupying such premises
or any part thereof.  Landlord may hold Tenant liable for all rent and other
indebtedness accrued to the date of such termination, plus, as  liquidated
damages and not as a penalty, an amount equal to the then present value of rent
provided for hereunder for the remaining portion of the Lease Term (had this
Lease not been terminated) using a ten (10%) percent value discount factor.  In
the event Landlord elects to terminate this Lease by reason of an event of
default, in lieu of recovering from Tenant under the preceding sentence,
Landlord may hold Tenant liable for the amount of all loss and damage which
Landlord may suffer by reason of such termination, whether through inability to
relet the Property on satisfactory terms or otherwise.

b.  Enter upon and take possession of the Property without terminating this
Lease, and expel or remove Tenant and any other person who may be occupying such
premises or any part thereof.  Landlord may relet the Property and receive the
rent therefor.  Tenant agrees to pay to Landlord monthly or on demand from time
to time any deficiency that may arise by reason of any such releting.  In
determining the amount of such deficiency, the brokerage commission, attorneys
fees, remodeling expenses and other costs of releting shall be subtracted from
the amount of rent received under such releting.

c.  Enter upon the property without terminating the Lease, and do whatever
Tenant is obligated to due under the terms of this Lease.  Tenant agrees to pay
Landlord on demand for expenses which Landlord may incur in thus effecting
compliance with Tenant's obligations under this Lease, together with interest
thereon at the rate of eighteen (18%) percent per annum from the date expended
until paid.  Landlord shall not be liable for any damages resulting to Tenant
from such action, whether caused by negligence of Landlord or otherwise.

d.  Tenant is presumed to have abandoned the Property if Tenant's goods,
equipment, or other property are removed from the Property in an amount
substantial enough to indicate a probable intent to abandon the Property and
such removal is not within the normal course of Tenant's business.  In the event
that Tenant is presumed to have abandoned the Property, Landlord may remove and
store any property of tenant that remains on the Property.  Landlord may store
such property at any location satisfactory to Landlord.  Landlord may dispose of
such stored property after the expiration of sixty (60) days after the date the
property was stored.  Landlord shall deliver by certified mail to Tenant at
Tenant's last known address as shown by Landlord's records a notice stating that
Landlord may dispose of Tenant's property if Tenant does not claim the same
within sixty (60) days after the date the property was stored.

e.  In the event Tenant is in default under this Lease by reason of Tenant's
failure to pay rent as set forth above, then Landlord may, at Landlord's option,
change all door locks and leave a written notice on a door to Tenant's premises
slating the name and address or telephone number of the individual from whom a
new key can be obtained during Tenant's regular business hours, which are
defined for this purpose as being between 9:00 a.m. and 5:00 p.m. on Monday
through

                                       9
<PAGE>
 
Friday of each week.  Tenant hereby waives the three (3) days written
notice to vacate required by Texas Property Code Section 24.005 and agrees that
one (1) day written notice to vacate is sufficient for purposes of Texas
Property Code Section 24.005 and the filing of a Forcible Entry and Detainer
lawsuit.

Upon the occurrence of any such events of default, Landlord may enter upon and
take possession of the Property by force, if necessary, without being liable for
prosecution of any claim for damages therefor.  Pursuit of any of the foregoing
remedies shall not preclude pursuit of any of the other remedies herein provided
or any other remedies provided by law, nor shall pursuit of any remedy herein
provided substitute a forfeiture or waiver of any rent due to Landlord hereunder
or of any damages accruing to Landlord by reason of the violation of any of the
terms, conditions and convenants herein contained.

ARTICLE TEN:  REALTOR'S COMMISSIONS

10.01  AMOUNT AND MANNER OF PAYMENT OF LEASE COMMISSIONS.  Landlord agrees to
pay to the Principal Realtor a commission for negotiating this Lease equal to
the percentage stated in Section 1.15A of the total rent to become due to the
Landlord during or because of (i) the Lease Term; (ii) each period of occupancy
of the Property by Tenant, its affiliates, successors or assign, beyond the
Lease Term, whether such continued occupancy be caused by renewal, extension,
holding over, new lease or agreement or otherwise and whether upon the same or
different terms, conditions of covenants of this Lease; (iii) any expansion,
lease extension, renewal or other rental agreement with Landlord, its
affiliates, successor or assigns, demising to Tenant, its affiliates, successors
or assigns, any premises located on or constituting all or part of any tract or
parcel of real property adjoining, adjacent to or contiguous to the Property.
Said lease commission shall be paid in accordance with Section 1.15A.  If the
lease commission is payable in cash under Section 1.15A(ii), the lease
commission for any continued occupancy or expansion, as provided above, shall be
payable in cash for the entire term of any such continued occupancy or expansion
at the beginning of such term and at the beginning of any subsequent term.
Notwithstanding that Principal Realtor, or Cooperating Realtor, may be
designated under Section 1.11 to receive rent hereunder and may from time to
time gratuitously perform rent collection and limited property management
services for Landlord, neither Principal Realtor, nor Cooperating Realtor shall
have any obligation under this Lease to perform such rent collection and
management services, unless such obligation arises from a separate agreement
with Landlord that provides for an additional  fee for such services.

10.02  COMMISSION ON PURCHASE.  In the event Tenant, its affiliates, successors
or assigns, should purchase the Property during the term of this Lease (as the
same may be renewed or extended) and for a period of one hundred twenty (120)
days after Tenant, its affiliates, successors or assigns, vacates the Property,
Landlord shall pay to the undersigned Principal Realtor a sales commission in
cash equal to the percentage stated in Section 1.15B of the purchase price
payable at the closing.  Upon the closing of such sale, the lease commission
payments shall terminate if the lease commission is payable in installments in
accordance with Section 1.15A(i); or, in the event the lease commission is
payable in case in accordance with Section 1.15A(ii), Landlord shall receive a
credit against the sales commission equal to the total lease commission paid by
Landlord to the Principal Realtor multiplied by the unexpired 

                                       10
<PAGE>
 
percentage of the Lease Term as of the date of such closing. (In the event the
Principal Realtor is paid a lease commission in cash in accordance with Section
1.15A(ii) for any continued occupancy beyond the Lease Term or expansion, such
credit shall be equal to the total lease commission paid for such continued
occupancy or expansion multiplied by the unexpired percentage of the term of
such continued occupancy or expansion as of the date of such closing.

10.03  PROTECTION OF REALTORS.  If Landlord sells the Property, or assigns
Landlord's interest in this Lease, the buyer or assignee shall, by accepting
such conveyance of the Property or assignment of the lease, be conclusively
deemed to have agreed to make all payments to Principal Realtor thereafter
required of Landlord under this Article Ten.  Principal Realtor shall have the
right to bring a legal action to enforce or declare rights under this provision.
The prevailing party in such action shall be entitled to reasonable attorneys
fees to be paid by the losing party.  This section is included in this lease for
the benefit of Principal Realtor.

10.04  REALTOR'S LIEN.  The Principal Realtor is hereby granted a lien against
the Property to secure payment of all commissions payable under this Article Ten
(including any additional commissions which may hereafter become payable by
reason of renewals, new leases, rental agreements, sales or otherwise).  This
lien is subject to the rights of Tenant under this lease, but prior an superior
to any liens hereafter created against the Property, excepting only liens in
favor of banks, insurance companies, savings and loan associations and similar
regulated financial institutions securing indebtedness incurred for the purpose
of acquiring the Property of constructing, repairing, rebuilding or remodeling
buildings and other improvements thereon, to all of which liens the lien hereby
created shall be subordinate and inferior.

10.05  PAYMENT TO PRINCIPAL REALTOR.  Landlord shall be liable for payment of
all commissions to Principal Realtor only, whereupon it shall be protected from
any claims from any Cooperating Realtor or Broker.

ARTICLE ELEVEN:  CONDEMNATION

Landlord shall notify Tenant if Landlord receives notice of any potential
condemnation of the Property or portion thereof.  If all or any portion of the
Property is taken under the power of eminent domain or sold under the threat of
that power (all of which are called "Condemnation"), this Lease shall terminate
as to the part taken or sold on the date the condemning authority takes title or
possession, by delivering written notice to the other within ten (10) days after
receipt of written notice of such taking (or in the absence of such notice,
within ten (10) days after the condemning authority takes possession).  If
neither Landlord nor Tenant terminates this Lease, this Lease shall remain in
effect as to the portion of the Property not taken, except that the rent shall
be reduced in proportion to the reduction in floor area of the Property.  Any
Condemnation award or payment shall be distributed in the following order; (a)
first, to any ground lessor, mortgagee or beneficiary under a deed of trust
encumbering the Property, the amount of its interest in the Property; (b)
second, to Tenant, only the amount of any award specifically designated for loss
of or damage to Tenant's trade fixtures or removable personal property; and (c)
third, to Landlord, the remainder of such award, whether as compensation for
reduction in the value of the leasehold, the taking of the fee, or otherwise.
If this Lease is not terminated, 

                                       11
<PAGE>
 
Landlord shall repair any damage to the Property caused by the Condemnation,
except that Landlord shall not be obliged to repair any damage for which Tenant
has been reimbursed by the condemning authority. If the severance damages
received by Landlord are not sufficient to pay for such repair, Landlord shall
have the right to either terminate this Lease or make such repair at Landlord's
expense.

ARTICLE TWELVE:  TAXES

12.01  PAYMENT BY TENANT.  Tenant shall pay the real estate taxes on the
Property during the Lease Term.

12.02  PAYMENT BY TENANT.  Tenant shall pay the party named in Section 1.11
above, as additional rental, the excess, if any, of the real estate taxes on the
Property for any year during the Lease Term over the real estate taxes on the
Property for the base year stated in Section 1.10.  Tenant shall make such
payment within fifteen (15) days after receipt of a statement showing the amount
and computation of such increase.  Tenant shall be responsible for the pro-rata
portion of such additional rental for any fractional part of a year preceding
the end of the Lease Term, which prorated sum shall be due and payable upon the
termination of this Lease.  If the termination of this Lease occurs before the
tax rate is fixed for the particular year, the proration shall be upon the basis
of the tax rate for the preceding year applied to the latest assessed valuation,
and notwithstanding the termination of this Lease, any difference in the actual
real estate taxes for such year shall be adjusted between the parties upon
receipt of written evidence of the payment thereof.  Tenant agrees to pay all
personal property taxes levied against the leased premises and Tenant during the
term hereof by reason of Tenant's improvements, inventory, equipment and
business conducted at the leased premises.

12.03  JOINT ASSESSMENT.  If the Property is not separately assessed, Tenant's
share of the real estate taxes payable by Tenant under Section 12.02 shall be
determined from reasonably available information.  Landlord shall make a
reasonable determination of Tenant's proportionate share of such real estate
taxes and Tenant shall pay such share to Landlord within fifteen (15) days after
receipt of Landlord's written statement.

12.04  CONTEST BY TENANT.  Tenant may, at its own expense, contest any tax
assessment for which Tenant may be wholly or partially responsible.  Except as
hereinafter provided, Tenant need not pay the tax, assessment or charge during
the pendency of the contest and Tenant may prevent Landlord from paying any tax,
assessment or charge that Tenant is contesting pursuant to this section 12.04,
pending any resolution of the contest, by depositing with Landlord, before such
tax, assessment or charge becomes delinquent, Tenant's portion of the full
amount of the tax or assessment, plus the full amount of any penalty that might
be imposed for failure to make timely payment and six (6) months of interest at
the rate imposed by the entity levying the tax or assessment.  Upon final
resolution of the tax or assessment contest, Landlord may use the money
deposited by Tenant to pay Tenant's portion of any tax or assessment, plus the
full amount of any penalty or interest, due under the final resolution, and
Tenant shall receive the balance of the deposit, if any.  If the deposit is
insufficient to pay these amounts, Tenant must immediately pay such
insufficiency to Landlord.  Notwithstanding the foregoing, Landlord may pay, or
require 

                                       12
<PAGE>
 
Tenant to pay, any tax, assessment or charge, or any portion thereof, for which
Tenant is responsible under this Article Twelve, pending resolution of Tenant's
contest of the tax, assessment or charge, if payment is demanded by a holder of
a mortgage on the property, or if failure to pay will subject all or part of the
Property to forfeiture or loss. Landlord reserves the right to contest any tax,
assessment or charge on the Property.

ARTICLE THIRTEEN:  LANDLORD'S LIEN

In addition to the statutory landlord's lien, Tenant hereby grants to Landlord a
security interest to secure payment of all rent and other sums of money becoming
due hereunder from Tenant, upon all goods, wares, equipment, fixtures, furniture
and other personal property of Tenant situated in or upon the Property, together
with the proceeds from the sale or lease thereof.  Such property shall not be
removed without the consent of Landlord until all arrearages in rent and other
sums of money then due to Landlord hereunder shall first have been paid and
discharged.  Upon request by Landlord, Tenant agrees to execute and deliver to
Landlord a financing statement in form sufficient to perfect the security
interest of Landlord in the aforementioned property and proceeds thereof under
the provisions of the Uniform Commercial Code in force in the State of Texas.

ARTICLE FOURTEEN:  SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE

14.01  SUBORDINATION.  Landlord shall have the right to subordinate this lease
to any ground lease, deed of trust or mortgage encumbering the Property, and
advances made on the security thereof and any renewals, modifications,
consolidations, replacements or extensions thereof, whenever made or recorded.
However, Tenant's right to quiet possession of the Property during the Lease
Term shall not be disturbed if Tenant pays the rent and performs all of Tenant's
obligations under this Lease and is not otherwise in default.  If any ground
lessor, beneficiary or mortgagee elects to have this Lease prior to the lien of
its ground lease, deed of trust or mortgage and gives written notice thereof to
Tenant, this Lease shall be deemed prior to such ground lease, deed of trust or
mortgage whether this lease is dated prior or subsequent to the date of said
ground lease, deed of trust or mortgage or the date of recording thereof.

14.02  ATTORNMENT.  If Landlord's interest in the Property is acquired by any
ground lessor, beneficiary under a deed of trust, mortgage or purchaser at a
foreclosure sale, Tenant shall attorn to the transferee of or successor to
Landlord's interest in the Property and recognize such transferee or successor
as landlord under this Lease.  Tenant waives the protection of any statue or
rule of law which gives or purports to give Tenant any right to terminate this
Lease or surrender possession of the property upon the transfer of Landlord's
interest.

14.03  SIGNING OF DOCUMENTS.  Tenant shall sign and deliver any instruments or
documents necessary or appropriate to evidence any such attornment or
subordination or agreement to do so.  If Tenant fails to do so within ten (10)
days after written request, Tenant hereby makes, constitutes and irrevocably
appoints Landlord, or any transferee or successor of Landlord the attorney-in-
fact of Tenant to execute and deliver any such instrument or document.

                                       13
<PAGE>
 
14.04 ESTOPPEL CERTIFICATES.

a.  Upon Landlord's written request, Tenant shall execute, acknowledge and
deliver to Landlord a written statement certifying (i) that none of the terms or
provisions of this Lease have been charged (or if they have been charged,
stating how they have been changed); (ii) that this Lease has not been canceled
or terminated; (iii) the last due date of payment of the rent and other changes
and the time period covered by such payment; and (iv) that Landlord is not in
default under this Lease (or, if Landlord is claimed to be in default, stating
why).  Tenant shall deliver such statement to Landlord within ten (10) days
after Landlord's request.  Any such statement by Tenant may be given to Landlord
to any prospective purchaser or encumbrancer of the Property.  Such purchaser or
encumbrancer may rely conclusively upon such statement as true and correct.

b.  If Tenant does not deliver such statement to Landlord within such ten (10)
day period, Landlord, and any prospective purchaser or encumbrancer, may
conclusively presume and rely upon the following facts:  (i) that the terms and
provisions of this Lease have not been changed except as otherwise represented
by Landlord; (ii) that this Lease has not been cancelled or terminated except as
otherwise represented by the Landlord; (iii) that not more than one month's rent
or other charges have been paid in advance; and (iv) that Landlord is not in
default under the Lease.  In such event, Tenant shall be estopped from denying
the truth of such facts.

ARTICLE II.:  LEASE AND LEASE TERM

2.01. Lease of Property for Lease Term. Landlord leases the Property to Tenant 
and Tenant leases the Property from Landlord for the Lease Term stated in
Section 1.05. As used herein, the "Commencement Date" shall be the date
specified in Section 1.05 for the beginning of the Lease Term, unless advanced
or delayed under any provision of this Lease.

2.02. Delay in Commencement. Landlord shall not be liable to Tenant if Landlord
does not deliver possession of the Property to Tenant on the first date
specified in Section 1.05 above. Landlord's non-delivery of the Property to
Tenant on that date shall not affect this Lease or the obligations of Tenant
under this Lease. However, the Commencement Date shall be delayed until
possession of the Property is delivered to Tenant. The Lease Term shall be
extended for a period equal to the delay in delivery of possession of the
Property to Tenant, plus the number of days necessary to end the Lease Term on
the last day of a month. If Landlord does not deliver possession of the Property
to Tenant within sixty (60) days after the first date specified in Section 1.05
above, Tenant may elect to cancel this Lease by giving written notice to
Landlord within ten (10) days after the 60-day period ends. If Tenant gives such
notice, the Lease shall be cancelled effective as of the date of its execution,
and no party hereto shall have any obligations, one to the other. If Tenant does
not give such notice, Tenant's right to cancel the Lease shall expire and the
Lease Term shall commence upon the delivery of possession of the Property to
Tenant. If delivery of possession of the Property to Tenant is delayed, Landlord
and Tenant shall, upon such delivery, execute an amendment to this Lease setting
forth the Commencement Date and expiration date of the Lease.

2.03. Early Occupancy. If Tenant occupies the Property prior to the Commencement
Date, Tenant's occupancy of the Property shall be subject to all of the
provisions of this Lease. Early occupancy of the Property shall not advance the
expiration date of this Lease. Tenant shall pay Base Rent and all other charges
specified in this Lease for the occupancy period.
<PAGE>
 
2.04. Holding Over. Tenant shall vacate the Property upon the expiration or
earlier termination of this Lease. Tenant shall reimburse Landlord for and
indemnify Landlord against all damages incurred by Landlord from any delay by
Tenant in vacating the Property. If Tenant does not vacate the Property upon the
expiration or earlier termination of the Lease, Tenant's occupancy of the
Property shall be a "month-to-month" tenancy, subject to all of the terms of
this Lease, applicable to a month-to-month tenancy, subject to all the terms of
this Lease applicable to a month-to-month tenancy, except that the Base Rent
then in effect shall be increased by fifty percent (50%).

ARTICLE III:  RENT AND SECURITY DEPOSIT

3.01. Manner of Payment. All sums to become due hereunder by Tenant shall be
made to the party named in Section 1.13 above, at the address stated herein for
such party, unless such address is changed as provided herein. Any and all
payments made to the Principal REALTOR for the account of Landlord shall be
deemed made to Landlord when received by the Principal REALTOR. All sums payable
by Tenant hereunder, whether or not expressly denominated as rent, shall
constitute rent for the purposes of section 502(b)(7) of the Bankruptcy Code.

3.02. Time of Payment. Upon execution hereof, Tenant shall pay the rent for the
first month of the Lease Term. On or before the first day of the second month of
the Lease Term and of each month thereafter, a like monthly installment shall be
due and payable, in advance, without off-set, deduction or prior demand. If the
Lease Term commences or ends during a calendar month, the rent for any
fractional calendar month following the Commencement Date or preceding the end
of the Lease Term shall be prorated by days.

3.03. Late Charges. Tenant's failure to pay sums due hereunder promptly may
cause Landlord to incur unanticipated costs. The exact amount of such costs are
impractical or extremely difficult to ascertain. Such costs may include, but are
not limited to, processing and accounting charges and late charges which may be
imposed on Landlord by any ground lease, deed of trust or mortgage encumbering
the Property. Therefore, if any sum due hereunder is not received on its due
date, Tenant shall pay the party named in Section 1.13 above a late charge equal
to the sum stated in Section 1.14 above for each day from its due date until
such delinquent sum is received. If any check tendered in payment of any sum due
from Tenant hereunder is returned for any reason, Tenant shall pay a late charge
for each day from said due date until such check is made good. The parties agree
that such late charge represents a fair and reasonable estimate of the costs
Landlord will incur by reason of such late payment of such returned check.

3.04. Security Deposit. Upon execution hereof, Tenant shall deposit with the
party named in Section 1.13 above a cash Security Deposit in the sum stated in
Section 1.07. Landlord may apply all or part of the Security Deposit to any
unpaid rent or other charges due from Tenant or to cure any other defaults of
Tenant. If Landlord uses any part of the Security Deposit, Tenant shall restore
the Security Deposit to its full amount within ten (10) days after Landlord's
written request. Tenant's failure to do so shall be a material default under
this Lease. No interest shall be paid on the Security Deposit. Landlord shall
not be required to keep the Security Deposit separate from its other accounts
and no trust relationship is created with respect to the Security 
<PAGE>
 
Deposit. Upon any termination of this Lease not resulting from Tenant's default,
and after Tenant has vacated the Property in the manner required by this Lease.
Landlord shall refund the unused portion of the Security Deposit to Tenant.

ARTICLE IV.:  TAXES

4.01. Payment by Landlord. Landlord shall pay the real estate taxes on the
Property during the Lease Term.

4.02. Payment by Tenant. Tenant shall pay the party named in Section 1.13 above,
as additional rental, the excess, if any, of the real estate taxes for any year
during the Lease Term over the real estate taxes for the base year stated in
Section 1.12. Tenant shall make such payment within fifteen (15) days after
receipt of a statement showing the amount and computation of such increase.
Tenant shall be responsible for the pro-rata portion of such additional rental
for any fractional part of a year preceding the end of the Lease Term, which
prorated sum shall be due and payable upon the termination of this Lease. If the
termination of this Lease occurs before the tax rate is fixed for the particular
year, the proration shall be upon the basis of the tax rate for the preceding
year applied to the latest assessed valuation, and notwithstanding the
termination of this Lease, any difference in the actual real estate taxes for
such year shall be adjusted between the parties upon receipt of written evidence
of the payment thereof.

4.03. Improvements by Tenant. In the event the real estate taxes levied against
the Property for the real estate tax year in which the Lease Term commences are
increased as a result of any alterations, additions or improvements made by
Tenant or by Landlord at the request of Tenant, Tenant shall pay to Landlord
upon demand the amount of such increase. For the purposes of the calculations
under Section 4.02, the amount of the real estate taxes during the real estate
tax year in which the Lease Term commences shall not include any taxes resulting
from any such alterations, additions or improvements made in or to the Property.
Landlord shall obtain from the tax assessor or assessors a written statement of
the total amount of such increase.

4.04. Joint Assessment. If the real estate taxes are assessed against the
Property jointly with other property not constituting a part of the Property,
the real estate taxes for such years shall be equal to the amount bearing the
same proportion to the aggregate assessment that the total square feet of
building area in the Property bears to the total square feet of building area
included in the joint assessment.

4.05. Personal Property Taxes. Tenant shall pay all taxes charged against trade
fixtures, furnishings, equipment or any other personal property belonging to
Tenant. Tenant shall try to have its personal property taxed separately from the
Property, but if any of Tenant's personal property is taxed with the Property,
Tenant shall pay the taxes for the personal property within fifteen (15) days
after Tenant receives a written statement for such personal property taxes.

ARTICLE V.:  INSURANCE AND INDEMNITY

5.01. Casualty Insurance. During the Lease Term, Landlord shall maintain
policies of insurance covering loss of or damage to the Property in such amount
or percentage of replacement value as Landlord or its insurance advisor deems
reasonable in relation to the age, location, type of construction and physical
condition of the Property and the availability of such insurance at reasonable
rates. Such policies shall provide protection against all perils included within
the classification of fire and extended coverage and any other perils which
Landlord deems necessary. Landlord may obtain insurance coverage for Tenant's
fixtures, equipment or building improvements installed by Tenant in or on the
Property. Tenant shall, at Tenant's expense, maintain such primary or additional
insurance on its fixtures, equipment and building improvements as Tenant deems
necessary to protect its interest. Tenant shall not do or permit to be done
anything which invalidates any such insurance polices. Any casualty insurance
which may be carried by Landlord or Tenant shall be for the sole benefit of the
party carrying such insurance and under its sole control.

5.02. Increase in Premiums. Tenant shall not permit any operation or activity to
be conducted or storage or use of any volatile or any other materials on the
Property that would cause suspension or cancellation of any fire and extended
coverage insurance policy carried by Landlord, or increase the premiums
therefor, without the prior written consent of Landlord. If Tenant's use and
occupancy of the Property causes an increase in the premiums for any fire and
extended coverage insurance policy carried by Landlord on the day before Tenant
shall have first gone into possession of the Property under this Lease, Tenant
shall pay, as additional rental, the amount of such increase to Landlord upon
demand and presentation of written evidence of the increase by Landlord.

5.03. Liability Insurance. During the Lease Term, Tenant shall maintain a policy
of comprehensive public liability insurance, at Tenant's expense, insuring
Landlord against liability arising out of the ownership, use, occupancy or
maintenance of the Property. The initial amount of such insurance shall be at
least $1,000,000, and shall be subject to periodic increase based upon
inflation, increased liability awards, recommendation of professional insurance
advisors, and other relevant factors. However, the amount of such insurance
shall not limit Tenant's liability nor relieve Tenant of any obligation
hereunder. The policy shall contain cross-liability endorsements, if applicable,
and shall insure Tenant's performance of the indemnity provisions of Section

5.04. Such policy shall contain a provision which prohibits cancellation or
modification of the policy except upon thirty (30) days' prior written notice to
Landlord. Tenant may discharge its obligations under this Section by naming
Landlord as an additional insured under a policy of comprehensive liability
insurance maintained by Tenant and containing the coverage and provisions
described in this Section. Tenant shall deliver a copy of such policy or
certificate (or a renewal thereof) to Landlord prior to the Commencement Date
and prior to the expiration of any such policy during the Lease Term. If Tenant
fails to maintain such policy, Landlord may elect to maintain such insurance at
Tenant's expense. Tenant shall, at Tenant's expense, maintain such other
liability insurance as Tenant deems necessary to protect Tenant.
<PAGE>
 
5.04. Indemnity. Landlord shall not be liable to Tenant or to Tenant's
employees, agents or visitors, or to any other person, whomsoever, for any
injury to persons or damage to property on or about the Property or any adjacent
area owned by Landlord caused by the negligence or misconduct of Tenant, its
employees, subtenants, licensees or concessionaires or any other person entering
the Property under express or implied invitation of Tenant, or arising out of
the use of the property by Tenant and the conduct of its business therein, or
arising out of any breach or default by Tenant in the performance of its
obligations hereunder; and Tenant hereby agrees to indemnify Landlord and hold
it harmless from any loss, expense or claims arising out of such damage or
injury. Tenant shall not be liable for any injury or damage caused by the
negligence or misconduct of Landlord, or its employees or agents, and Landlord
agrees to indemnify Tenant and hold it harmless from any loss, expense or damage
arising out of such damage or injury.

5.05. Waiver of Subrogation. Each party hereto waives any and every claim which
arises or may arise in its favor against the other party hereto during the term
of this Lease or any renewal or extension thereof for any and all loss of, or
damage to, any of its property located within or upon, or constituting a part
of, the Property, which loss or damage is covered by valid and collectible fire
and extended coverage insurance policies, to the extent that such loss or damage
is recoverable under such insurance policies. Such mutual waivers shall be in
addition to, and not in limitation or derogation of, any other waiver or release
contained in this Lease with respect to any loss of, or damage to, property of
the parties hereto. Inasmuch as such mutual waiver will preclude the assignment
of any aforesaid claim by way of subrogation or otherwise to an insurance
company (or any other person), each party hereby agrees immediately to give to
each insurance company which has issued to it policies of fire and extended
coverage insurance, written notice of the terms of such mutual waivers, and to
cause such insurance policies to be properly endorsed, if necessary, to prevent
the invalidation of such insurance coverages by reason of such waivers.

ARTICLE VI.:  USE OF PROPERTY

6.01. Permitted Use. Tenant may use the Property only for the permitted use
stated in Section 1.08.

6.02. Compliance with Law. Tenant shall comply with all governmental laws,
ordinances and regulations applicable to the use of the Property, and shall
promptly comply with all governmental orders and directives for the correction,
prevention and abatement of nuisances in or upon, or connected with the
Property, all at Tenant's sole expense.

6.03. Certificate of Occupancy. Tenant may, prior to the commencement of the
term of this Lease, apply for a Certificate of Occupancy to be issued by the
municipality in which the Property is located, but this Lease shall not be
contingent upon issuance thereof. Nothing herein contained shall obligate
Landlord to install any additional electrical wiring, plumbing or plumbing
fixtures which are not presently existing on the Property, or which have not
been expressly agreed upon by Landlord in writing.

6.04. Signs. Without the prior written consent of Landlord, Tenant shall not
place or affix any signs or other objects upon or to the Property, including but
not limited to the roof or exterior 
<PAGE>
 
walls of the building or other improvement thereon, or paint or otherwise deface
said exterior walls. Any signs installed by Tenant shall conform with applicable
laws and deed and other restrictions. Tenant shall remove all signs at the
termination of this Lease and shall repair any damage and close any holes caused
or revealed by such removal.

6.05. Utility Services. Tenant shall pay the cost of all utility services,
including but not limited to initial connection charges, all charges for gas,
water and electricity used on the Property, and for all electric lights, lamps
and tubes.

6.06. Landlord's Access. Landlord and its authorized agents shall have the
right, during normal business hours, to enter the Property (a) to inspect the
general condition and state of repair thereof, (b) to make repairs required or
permitted under this Lease, (c) to show the property to any prospective tenant
or purchaser or (d) for any other reasonable purpose. During the final 150 days
of the lease Term, Landlord and its authorized agents shall have the right to

6.07. Quiet Possession. If Tenant pays the rent and complies with all other
terms of this Lease, Tenant may occupy and enjoy the Property for the full Lease
Term, subject to the provisions of this Lease.

6.08. Exemptions from Liability. Landlord shall not be liable for any damage or
injury to the person, business (or any loss of income therefrom), goods, wares,
merchandise or other property of Tenant, Tenant's employees, invitees, customers
or any other person in or about the Property, whether such damage or injury is
caused by or results from: (a) fire, steam, electricity, water, gas or rain; (b)
the breakage, leakage, obstruction or other defects of pipes, sprinklers, wires,
appliances, plumbing, air conditioning or lighting fixtures or any other cause;
(c) conditions arising on or about the Property or upon other portions of any
building of which the Property is a part, or from other sources or places; or
(d) any act or omission of any other tenant of any building of which the
Property is a part. Landlord shall not be liable for any such damage or injury
even though the cause of or the means of repairing such damage or injury are not
accessible to Tenant. The provisions of this Section 6.08 shall not, however,
exempt Landlord from liability for Landlord's gross negligence or willful
misconduct.

ARTICLE VII.:  MAINTENANCE, REPAIRS AND ALTERATIONS

7.01. Acceptance of Premises. Tenant acknowledges that it has fully inspected
the Property and accepts the Property in its condition as of the execution of
this Lease as suitable for the purposes for which it is leased. Tenant
acknowledges that, except as stated in the following sentence, neither Landlord
nor an agent of Landlord has made any representation as to the condition of the
Property or the suitability of the Property for Tenant's intended use. Landlord
represents that on the Commencement Date, the plumbing, electrical system and
exterior doors, and any fire protection sprinkler system, heating system, air
conditioning equipment and elevators existing on the date of this Lease, are or
will be in good operating condition.
<PAGE>
 
7.02. Landlord's Obligation to Repair. Subject to the provisions of Article
Eight (Damage or Destruction) and Article Nine (Condemnation) and except for
damage caused by any act or omission of Tenant, Landlord shall keep the
foundation, roof and the structural portions of exterior walls of the
improvements of the Property in good order, condition and repair. However,
Landlord shall not be obligated to maintain or repair windows, doors, plate
glass or the surfaces of walls. In addition, Landlord shall not be obligated to
make any repairs under this Section until a reasonable time after receipt of
written notice from Tenant of the need of such repairs. If any repairs are
required to be made by Landlord, Tenant shall, at Tenant's sole cost and
expense, promptly remove Tenant's fixtures, inventory, equipment and other
Property, to the extent required to enable Landlord to make such repairs.
Landlord's liability hereunder shall be limited to the cost of such repairs or
corrections. Tenant waives the benefit of any present or future law which might
give Tenant the right to repair the Property at Landlord's expense or to
terminate the Lease because of the condition of the Property.

7.03. Tenant's Obligation to Repair. Subject to the provisions of the last
sentence of Section 7.01, the preceding Section 7.02, Article Eight (Damage or
Destruction) and Article Nine (Condemnation), Tenant shall, at all times, keep
that portion of the Property not required to be maintained by Landlord in good
order, condition and repair including but not limited to repairs (including all
necessary replacements) of the windows, plate glass, doors, heating system, air
conditioning equipment, fire protection sprinkler system, elevators, interior
and exterior plumbing and the interior of the building in general, and including
care of landscaping and regular mowing of grass and maintenance of any paving
and railroad siding. In addition, Tenant shall, at Tenant's expense, repair any
damage to the roof, foundation or structural portions of exterior walls caused
by Tenant's acts or omissions. If Tenant fails to maintain and repair the
property as required by this Section, Landlord may, on ten (10) days' prior
written notice, enter the Property and perform such maintenance or repair on
behalf of Tenant, except that no notice shall be required in case of emergency,
and Tenant shall reimburse Landlord for all costs incurred in performing such
maintenance or repair immediately upon demand.

7.04. Alterations, Additions and Improvements. Tenant shall not create any
openings in the roof or exterior walls, or make any alterations, additions or
improvements to the Property without the prior written consent of Landlord.
Consent for nonstructural alterations, additions or improvements shall not be
unreasonably withheld by Landlord. Tenant shall have the right to erect or
install shelves, bins, machinery, air conditioning or heating equipment and
trade fixtures, provided that Tenant complies with all applicable governmental
laws, ordinances and regulations. At the expiration or termination of this
Lease, Tenant shall, subject to the restrictions of Section 7.05 below, have the
right to remove such items so installed by it, provided Tenant is not in default
at the time of such removal and provided further that Tenant shall, at the time
of removal of such items, repair in a good and workmanlike manner any damage
caused by installation or removal thereof. Tenant shall pay for all costs
incurred or arising out of alterations, additions or improvements in or to the
Property and shall not permit a mechanic's or materialman's lien to be asserted
against the Property. Upon request by Landlord, Tenant shall deliver to Landlord
proof of payment reasonably satisfactory to Landlord of all costs incurred or
arising out of any such alterations, additions or improvements.
<PAGE>
 
7.05. Condition upon Termination. Upon the termination of the Lease, Tenant
shall surrender the Property to Landlord, broom clean and in the same condition
as received except for ordinary wear and tear which Tenant was not otherwise
obligated to remedy under any provision of the Lease. However, Tenant shall not
be obligated to repair any damage which Landlord is required to repair under
Article Eight (Damage or Destruction). In addition, Landlord may require Tenant
to remove any alterations, additions or improvements (whether or not made with
Landlord's consent) prior to the termination of the Lease and to restore the
Property to its prior condition, all at Tenant's expense. All alterations,
additions and improvements which Landlord has not required Tenant to remove
shall become Landlord's property and shall be surrendered to Landlord upon the
termination of the Lease. In no event, however, shall Tenant remove any of the
following materials or equipment without Landlord's prior written consent: any
power wiring or power panels; lighting or lighting fixtures; wall coverings;
drapes, blinds or other window coverings; carpets or other floor coverings;
heaters, air conditioners or any other heating or air conditioning equipment;
fencing or security gates; or other similar building operating equipment and
decorations.

ARTICLE VIII.:  DAMAGE OR DESTRUCTION

8.01. Notice. If the building or other improvements situated on the Property
should be damaged or destroyed by fire, tornado or other casualty, Tenant shall
immediately give written notice thereof to Landlord.

8.02  Partial Damage. If the building or other improvements situated on the
Property should be damaged by fire, tornado or other casualty but not to such an
extent that rebuilding or repairs cannot reasonably be completed within 120 days
from the date Landlord receives written notification by Tenant of the happening
of the damage, this Lease shall not terminate, but Landlord shall, at its sole
cost and risk, proceed forthwith and use reasonable diligence to rebuild or
repair such building and other improvements on the Property (other than
leasehold improvements made by Tenant or any assignee, subtenant or other
occupant of the Property) to substantially the condition in which they existed
prior to such damage; provided, however, if the casualty occurs during the final
18 months of the Lease Term, Landlord shall not be required to rebuild or repair
such damage unless Tenant shall exercise its renewal option (if any is contained
herein) within fifteen (15) days after the date of receipt by Landlord of the
notification of the occurrence of the damage. If Tenant does not elect to
exercise its renewal option or if there is no renewal option contained herein or
previously unexercised at such time, this Lease shall terminate at the option of
the Landlord and rent shall be abated for the unexpired portion of this Lease,
effective from the date of actual receipt by Landlord of the written
notification of the damage. If the building and other improvements are to be
rebuilt or repaired and are untenantable in whole or in part following such
damage, the rent payable hereunder during the period in which they are
untenantable shall be adjusted equitably.

8.03. Substantial or Total Destruction. If the building or other improvements
situated on the Property should be substantially or totally destroyed by fire,
tornado or other casualty, or so damaged that rebuilding or repairs cannot
reasonably be completed within 120 days from the date Landlord receives written
notification by Tenant of the happening of the damage, this Lease 
<PAGE>
 
shall terminate at the option of Landlord and rent shall be abated for the
unexpired portion of this Lease, effective from the date of receipt by Landlord
of such written notification. If this Lease is not terminated, the building and
the improvements shall be rebuilt or repaired and rent abated to the extent
provided under Section 8.02.

ARTICLE IX. CONDEMNATION

If, during the term of this Lease or any extension or renewal thereof, all or a
substantial part of the Property should be taken for any public or quasi-public
use under any governmental law, ordinance or regulation or by right of eminent
domain, or should be sold to the condemning authority under threat of
condemnation, this Lease shall terminate and the rent shall be abated during the
unexpired portion of this Lease, effective from the date of taking of the
Property by the condemning authority. If less than a substantial part of the
demised premises is taken for public or quasi-public use under any governmental
law, ordinance or regulation, or by right of eminent domain, or is sold to the
condemning authority under threat of condemnation, Landlord, at its option, may
by written notice terminate this Lease or shall forthwith at its sole expense
restore and reconstruct the buildings and improvements (other than leasehold
improvements made by Tenant or any assignee, subtenant or other occupant of the
Property) situated on the Property in order to make the same reasonably
tenantable and suitable for the use for which the Property is leased as defined
in Section 6.01. The rent payable hereunder during the unexpired portion of this
Lease shall be adjusted equitably. Landlord and Tenant shall each be entitled to
receive and retain such separate awards and portions of lump sum awards as may
be allocated to their respective interests in any condemnation proceedings. The
termination of this Lease shall not affect the rights of the respective parties
to such awards.

ARTICLE X.:  ASSIGNMENT AND SUBLETTING

     Tenant shall not, without the prior written consent of Landlord, assign
this Lease or sublet the Property or any portion thereof. Any assignment or
subletting shall be expressly subject to all terms and provisions of this Lease,
including the provisions of Section 6.01 pertaining to the use of the Property.
In the event of any assignment or subletting, Tenant shall remain fully liable
for the full performance of all Tenant's obligations under this Lease. Tenant
shall not assign its rights hereunder or sublet the Property without first
obtaining a written agreement from the assignee or sublessee whereby the
assignee or sublessee agrees to be bound by the terms of this Lease. No such
assignment or subletting shall constitute a novation. In the event of the
occurrence of an event of default while the Property is assigned or sublet,
Landlord, in addition to any other remedies provided herein or by law, may at
Landlord's option, collect directly from such assignee or subtenant all rents
becoming due under such assignment or subletting and apply such rent against any
sums due to Landlord hereunder. No direct collection by Landlord from any such
assignee or subtenant shall release Tenant from the performance of its
obligations hereunder.

ARTICLE XI.:  DEFAULT AND REMEDIES

11.01. Default. The following events shall be deemed to be events of default
under this Lease:
<PAGE>
 
       (a) Failure of Tenant to pay any installment of the rent or other sum
payable to Landlord hereunder on the date that same is due and such failure
shall continue for a period of ten (10) days;

       (b) Failure of Tenant to comply with any term, condition or covenant of
this Lease, other than the payment of rent or other sum of money, and such
failure shall not be cured within thirty (30) days after written notice thereof
to Tenant;

       (c) Tenant or any guarantor of Tenant's obligations hereunder shall
generally not pay its debts as they become due or shall admit in writing its
inability to pay its debts, or shall make a general assignment for the benefit
of creditors.

       (d) Tenant or any guarantor of Tenant's obligations hereunder shall
commence any case, proceeding or other action seeking reorganization,
arrangement, adjustment, liquidation, dissolution or composition of it or its
debts under any law relating to bankruptcy, insolvency, reorganization or relief
of debtors, or seeking appointment of receiver, trustee, custodian or other
similar official for it or for all or any substantial part of its property;

       (e) Any case, proceeding or other action against Tenant or any guarantor
of Tenant's obligations hereunder shall be commenced seeking to have an order
for relief entered against it as debtor, or seeking reorganization, arrangement,
adjustment, liquidation, dissolution or composition of it or its debts under any
law relating to bankruptcy, insolvency, reorganization or relief of debtors, or
seeking appointment of receiver, trustee, custodian or other similar official
for it or for all or any substantial part of its property, and Tenant (i) fails
to obtain a dismissal of such case, proceeding, or other action within sixty
(60) days of its commencement or (ii) converts the case from one chapter of the
Federal Bankruptcy Code to another chapter or (iii) is the subject of an Order
of Relief which is not fully stayed within seven business days after the entry
thereof.

       (f) Abandonment by Tenant of any substantial portion of the Property or
cessation of the use of the Property for the purpose leased.

11.02. Remedies. Upon the occurrence of any of the events of default listed in
Section 11.01, Landlord shall have the option to pursue any one or more of the
following remedies without any notice or demand whatsoever:

(a)    Terminate this Lease, in which event Tenant shall immediately surrender
the Property to Landlord. If Tenant fails to so surrender such premises,
Landlord may, without prejudice to any other remedy which it may have for
possession of the Property or arrearages in rent, enter upon and take possession
of the Property and expel or remove Tenant and any other person who may be
occupying such premises or any part thereof, by force if necessary, without
being liable for prosecution or any claim for damages therefor, Tenant shall pay
to Landlord on demand the amount of all loss and damage which Landlord may
suffer by reason of such termination, whether through inability to relet the
Property on satisfactory terms or otherwise;

(b)    Enter upon and take possession of the Property, by force if necessary,
without terminating
<PAGE>
 
this Lease and without being liable for the prosecution or for any claim for
damages therefor, and expel or remove Tenant and any other person who may be
occupying such premises or any part thereof. Landlord may relet the Property and
receive the rent therefor. Tenant agrees to pay to Landlord monthly or on demand
from time to time any deficiency that may arise by reason of any such reletting.
In determining the amount of such deficiency, the brokerage commission,
attorneys' fees, remodeling expenses and other costs of reletting shall be
subtracted from the amount of rent received under such reletting;

(c)    Enter upon the Property, by force, if necessary, without terminating this
Lease and without being liable for prosecution or for any claim for damages
therefor, and do whatever Tenant is obligated to do under the terms of this
Lease. Tenant agrees to pay Landlord on demand for expenses which Landlord may
incur in thus effecting compliance with Tenant's obligations under this Lease,
together with interest thereon at the rate of twelve percent (12%) per annum
from the date expended until paid. Landlord shall not be liable for any damages
resulting to Tenant from such action, whether caused by negligence of Landlord
or otherwise.

       Pursuit of any of the foregoing remedies shall not preclude pursuit of
any of the other remedies herein provided or any other remedies provided by law,
nor shall pursuit of any remedy herein provided constitute a forfeiture or
waiver of any rent due to Landlord hereunder or of any damages accruing to
Landlord by reason of the violation of any of the terms, conditions and
covenants herein contained.

11.03. Notice of Default. Tenant shall give written notice of any failure by
Landlord to perform any of its obligations under this Lease to Landlord and to
any ground lessor, mortgagee or beneficiary under any deed of trust encumbering
the Property whose name and address have been furnished to Tenant in writing.
Landlord shall not be in default under this Lease unless Landlord (or such
ground lessor, mortgagee or beneficiary) fails to cure such non-performance
within thirty (30) days after receipt of Tenant's notice. However, if such
non-performance reasonably requires more than thirty (30) days to cure, Landlord
shall not be in default if such cure is commenced within such thirty (30) day
period and thereafter diligently pursued to completion.

11.04. Limitation of Landlord's Liability. As used in this Lease, the term
"Landlord" means only the current owner or owners of the fee title to the
Property or the leasehold estate under a ground lease of the Property at the
time in question. Each Landlord is obligated to perform the obligations of
Landlord under this Lease only during the time such Landlord owns such interest
or title. Any Landlord who transfers its title or interest is relieved of all
liability with respect to the obligations of Landlord under this Lease to be
performed on or after the date of transfer. However, each Landlord shall deliver
to is transferee all funds previously paid by Tenant if such funds have not yet
been applied under the terms of this Lease.

ARTICLE XII.:  LANDLORD'S LIEN

       In addition to the statutory Landlord's lien, Tenant hereby grants to
Landlord a security interest to secure payment of all rent and other sums of
money becoming due hereunder from Tenant, upon all goods, wares, equipment,
fixtures, furniture and other personal property of Tenant situated in or upon
the Property, together with the proceeds from the sale or lease thereof. Such
property shall not be removed without the consent of Landlord until all
arrearages in rent
<PAGE>
 
and other sums of money then due to Landlord hereunder shall first have been
paid and discharged. Upon the occurrence of an event of default, Landlord may,
in addition to any other remedies provided herein or by law, enter upon the
Property and take possession of any and all goods, wares, equipment, fixtures,
furniture and other personal property of Tenant situated on the Property without
liability for trespass or conversion, and sell the same at public or private
sale, with or without having such property at the sale, after giving Tenant
reasonable notice of the time and place of any such sale. Unless otherwise
required by law, notice to Tenant of such sale shall be deemed sufficient if
given in the manner prescribed in this Lease at least ten (10) days before the
time of the sale. Any public sale made under this Article shall be deemed to
have been conducted in a commercially reasonable manner if held on the Property
or where the property is located, after the time, place and method of sale and a
general description of the types of property to be sold have been advertised in
a daily newspaper published in Dallas County, Texas, for five consecutive days
before the date of the sale. Landlord or its assigns may purchase at a public
sale and, unless prohibited by law, at a private sale. The proceeds from any
disposition dealt with in this Article, less any and all expenses connected with
the taking of possession, holding and selling of the property (including
reasonable attorneys' fees and legal expenses), shall be applied as a credit
against the indebtedness secured by the security interest granted herein. Any
surplus shall be paid to Tenant or as otherwise required by law; Tenant shall
pay any deficiencies forthwith. Upon request by Landlord, Tenant agrees to
execute and deliver to Landlord a financing statement in form sufficient to
perfect the security interest of Landlord in the aforementioned property and
proceeds thereof under the provisions of the Uniform Commercial Code in force in
the State of Texas. The statutory lien for rent is expressly reserved; the
security interest herein granted is in addition and supplementary thereto.

ARTICLE XIII.:  PROTECTION OF LENDERS

13.01. Subordination. Landlord shall have the right to subordinate this Lease to
any ground Lease, deed of trust or mortgage encumbering the Property, and
advances made on the security thereof and any renewals, modifications,
consolidations, replacements or extensions thereof, whenever made or recorded.
However, Tenant's right to quiet possession of the Property during the Lease
Term shall not be disturbed if Tenant pays the rent and performs all of Tenant's
obligations under this Lease and is not otherwise in default. If any ground
lessor, beneficiary or mortgagee elects to have this Lease prior to the lien of
its ground lease, deed of trust or mortgage and gives written notice thereof to
Tenant, this Lease shall be deemed prior to such ground lease, deed of trust or
mortgage and gives written notice thereof to Tenant, this Lease shall be deemed
prior to such ground lease, deed of trust or mortgage whether this Lease is
dated prior or subsequent to the date of said ground lease, deed of trust or
mortgage or the date of recording thereof.

13.02. Attornment. If Landlord's interest in the Property is acquired by any
ground lessor, beneficiary under a deed of trust, mortgagee or purchaser at a
foreclosure sale, Tenant shall attorn to the transferee of or successor to
Landlord's interest in the Property and recognize such transferee or successor
as Landlord under this Lease. Tenant waives the protection of any statute or
rule of law which gives or purports to give Tenant any right to terminate this
Lease or surrender possession of the Property upon the transfer of Landlord's
interest.
<PAGE>
 
13.03. Signing of Documents. Tenant shall sign and deliver any instruments or
documents necessary or appropriate to evidence any such attornment or
subordination or agreement to do so. If Tenant fails to do so within ten (10)
days after written request, Tenant hereby makes, constitutes and irrevocably
appoints Landlord, or any transferee or successor of Landlord, the
attorney-in-fact of Tenant to execute and deliver any such instrument or
document.

13.04. Estoppel Certificates.

(a)    Upon Landlord's written request, Tenant shall execute, acknowledge and
deliver to Landlord a written statement certifying: (i) that none of the terms
or provisions of this Lease have been changed (or if they have been changed,
stating how they have been changed); (ii) that this Lease has not been canceled
or terminated; (iii) the last date of payment of the Base Rent and other charges
and the time period covered by such payment; and (iv) that Landlord is not in
default under this Lease (or, if Landlord is claimed to be in default, stating
why). Tenant shall deliver such statement to Landlord within ten (10) days after
Landlord's request. Any such statement by Tenant may be given by Landlord to any
prospective purchaser or encumbrancer of the Property. Such purchaser or
encumberancer may rely conclusively upon such statement as true and correct.

(b)    If Tenant does not deliver such statement to Landlord within such ten
(10) day period, Landlord, and any prospective purchaser or encumbrancer, may be
conclusively presume and rely upon the following facts; (i) that the terms and
provisions of this Lease have not been changed except as otherwise represented

Lease by Landlord, Landlord shall obtain from the purchaser or assignee an

REALTOR on the date of closing of the sale of the Property or assignment of this
Lease. Landlord shall be released from personal liability for subsequent
payments of commissions only upon the delivery of such counterpart of said

                             OPTION TO EXTEND TERM

                                 LEASE RIDER*


     This Rider is attached to and made a part of that certain Lease Agreement
dated June 1, 1998 by and between Richard J. Ranger as Landlord, and
Higginbotham Audio/ Visual Solutions, as Tenant, covering the Property commonly
known as 10523 King William (the "Property").

A.  Option(s) to Extend Term

     1. Landlord hereby grants to Tenant one (1) option(x) (the "Option(x)") to
extend the Lease Term for additional term(s) of 3 years each (the
"Extension(s)"), on the same terms, conditions and covenants set forth in the
Lease Agreement, except as provided below. Each Option shall be exercised only
by written notice delivered to the Landlord at least one hundred twenty (120)
days before the expiration of the Lease Term or the preceding Extension of the
Lease Term. If Tenant fails to deliver Landlord written notice of the exercise
of an Option within the prescribed time period, such Option and any succeeding
Options shall lapse, and there shall be no further right to extend the Lease
Term. Each Option shall be exercisable by Tenant on the express condition that
at the time of the exercise, and at all times prior to the commencement of such
Extension(s), Tenant shall not be in default under any of the provisions of this
Lease. The foregoing Option(s) are personal to Tenant and may not be exercised
by any assignee or sub-tenant.

B.  Calculation of Rent

     The rent during the Extension(s) shall be determined by one of the
following methods (INDICATE YOUR CHOICE BY PUTTING AN "X" IN THE APPROPRIATE
BLANK UPON THE EXECUTION OF THE LEASE AGREEMENT):

         1.  Consumer Price Index Adjustment     ____________________________
         
         2.  Fair Rental Value Adjustment                     X
                                                 ---------------------------- 
         
         3.  Fixed Rental Adjustment             ____________________________

     1.  Consumer Price Index Adjustment

     The monthly rent during the particular Extension shall be determined by
multiplying the monthly rent during the Lease Term by a fraction determined as
follows:

          a.  The numerator shall be the latest index.

<PAGE>
 
          b.  The denominator shall be the initial index.

     If such computation would reduce the rent for the particular Extension, it
shall be disregarded, and the rent during the immediately preceding period shall
apply instead.

     The index shall mean the Consumer Price Index for Urban Consumers (all
items), Dallas-Fort Worth, Texas area (1967 = 100) published by the United
States Department of Labor, Bureau of Labor Statistics.

     The initial index shall mean the index published for the nearest calendar
month preceding the commencement date of the Lease Term. The latest index shall
mean the index published for the nearest calendar month preceding the first day
of the Extension.

     If a base year other than 1967 is adopted, the index shall be converted in
accordance with the appropriate conversion factor. If the index is discontinued
or revised, such other index or computation with which it is replaced shall be
used in order to obtain substantially the same result as would have been
obtained it if had not been discontinued or revised.

     2.  Fair Rental Value Adjustment

     The rent shall be increased on the first day of the particular Extension to
the "Fair Rental Value" of the Property, determined in the following manner:

          a.  If the Landlord and Tenant have not been able to agree on the Fair
Rental Value Adjustment prior to the date the option is required to be
exercised, the rent for the Extension shall be determined as follows: Within
fifteen (15) days following the exercise of the option, Landlord and Tenant
shall endeavor in good faith to agree upon a single appraiser. If Landlord and
Tenant are unable to agree upon a single appraiser within said fifteen (15) day
period, each shall then, by written notice to the other, given within ten (10)
days after said fifteen (15) day period, appoint one appraiser. The two
appraisers appointed by Landlord and Tenant shall be required to be first
approved by the then president of the Greater Dallas Board of REALTORS Inc. as
qualified to determine rental applicable to the Property. Within ten (10) days
after the two appraisers are appointed, they shall appoint a third appraiser. If
either Landlord or Tenant fails to appoint its appraiser within the prescribed
time period the single appraiser appointed shall determine the Fair Rental Value
of the Property. If the two appointed appraisers fail to agree on the third
appraiser, he shall be appointed by the then president of the Greater Dallas
Board of Realtors. Each party shall bear the cost of the appraiser appointed by
it and the parties shall share equally the cost of the third appraiser.

          b.  The "Fair Rental Value" of the Property shall mean the price that
a ready and willing tenant would pay as of the commencement of the Extension as
monthly rent to a ready and willing landlord of Property comparable to the
Property if such property were exposed for lease on the open market for a
reasonable period of time and taking into account all of the purposes for which
such property may be used and not just the use proposed to be made of the
<PAGE>
 
Property by Tenant. The Fair Rental Value of the Property shall be the average
of the two of the three appraisals which are closest in amount, and the third
appraisal shall be disregarded. In no event shall the rent by reduced by reason
of such computation. If the Fair Rental Value is not determined prior to the
commencement of the Extension, then Tenant shall continue to pay to Landlord the
rent applicable to the Property immediately prior to such Extension until the
Fair Rental Value is determined, and when it is determined, Tenant shall pay to
Landlord within ten (10) days after receipt of such notice the difference
between the rent actually paid by Tenant to Landlord and the new rent determined
hereunder.

     3.  Fixed Adjustments.

     The base rent shall be increased to the following amounts on the following
dates:

DATE:                                             AMOUNT:

N/A FIXED FOR 1 YEAR                               $1,906                       
- -----------------------------                     -----------------------------

may, without prejudice to any other remedy which it may have for possession of
the Property or arrearages in rent, enter upon and take possession of the

damages and not as a penalty, an amount equal to the then present value of rent
provided for hereunder for the remaining portion of the Lease Term (had this

                                      (5)

<PAGE>

b. Enter upon and take possession of the Property without terminating this 
Lease, and expel or remove Tenant and any other person who may be occupying such
premises or any part thereof. Landlord may relet the Property and receive the
rent therefor. Tenant agrees to pay to Landlord monthly or on demand from time
to time any deficiency that may arise by reason of any such reletting. In
determining the amount of such deficiency, the brokerage commission, attorneys
fees, remodeling expenses and other costs of reletting shall be subtracted from
the amount of rent received under such reletting.

c. Enter upon the Property without terminating the Lease, and do whatever Tenant
is obligated to due under the terms of this Lease. Tenant agrees to pay Landlord
on demand for expenses which Landlord may incur in thus effecting compliance 
with Tenant's obligations under this Lease, together with interest thereon at 
the rate of eighteen (18%) percent per annum from the date expended until paid. 
Landlord shall not be liable for any damages resulting to Tenant from such 
action, whether caused by negligence of Landlord or otherwise.

d. Tenant is presumed to have abandoned the Property if Tenant's goods, 
equipment, or other property are removed from the Property in an amount 
substantial enough to indicate a probable intent to abandon the Property and 
such removal is not within the normal course of Tenant's business. In the event 
that Tenant is presumed to have abandoned the Property, Landlord may remove and 
store any property of Tenant that remains on the Property. Landlord may 
store such property at any location satisfactory to Landlord. Landlord may 
dispose of such stored property after the expiration of sixty (60) days from the
date such property is so stored. Landlord shall deliver by certified mail to 
Tenant at Tenant's last known address as shown by Landlord's records a notice 
stating that Landlord may dispose of Tenant's property if Tenant does not claim 
the same within sixty (60) days after the date property was stored.

e. In the event Tenant is in default under this Lease by reason of Tenant's 
failure to pay rent as set forth above, then Landlord may, at Landlord's option,
change all door locks and leave a written notice on a door to Tenant's leased 
premises stating the name and address or telephone number of the individual from
whom a new key can be obtained during Tenant's regular business hours, which are
defined for this purpose as being between 8.00 a.m. and 5.00 p.m. on Monday 
through Friday of each week, Tenant hereby waives the three (3) days written 
notice to vacate required by Texas Property Code Section 24.005 and agrees that 
one (1) day written notice to vacate is sufficient for the purpose of Texas 
Property Code Section 24.005 and the filing of a Forcible Entry and Detainer 
lawsuit.

Upon the occurrence of any of such events of default, Landlord may enter upon
and take possession of the Property by force, if necessary, without being liable
for prosecution of any claim for damages therefor. Pursuit of any of the
foregoing remedies shall not preclude pursuit of any of the other remedies
herein provided or any other provided by law, nor shall pursuit of any remedy
herein provided constitute a forfeiture or waiver of any rent due to landlord
hereunder or of any damages accruing to Landlord by reason of the violation of
the terms, conditions and covenants herein contained.

condemnation of the Property or portion thereof. If all or any portion of the
Property is taken under the power of eminent domain or sold under the threat of
that power (all of which are called "Condemnation"), this Lease shall terminate
as to the part taken or sold on the date the condemning authority takes title or
possession, by delivering written notice to the other within ten (10) days after
receipt of written notice of such taking (or in the absence of such notice,
within ten (10) days after the condemning authority takes possession). If
neither Landlord nor Tenant terminates this Lease, this Lease shall remain in
effect as to the portion of the Property not taken, except that the rent shall
be reduced in proportion to the reduction in floor area of the Property. Any
Condemnation award or payment shall be distributed in the following order: (a)
first, to any ground lessor, mortgagee or beneficiary under a deed of trust
encumbering the Property, the amount of its interest in the Property; (b)
second, to Tenant, only the amount of any award specifically designated for loss
of or damage to Tenant's trade fixtures or removable personal property; and (c)
third, to Landlord, the remainder of such award, whether as compensation for
reduction in the value of the leasehold, the taking of the fee, or otherwise.
If this Lease is not terminated, Landlord shall repair any damage to the
Property caused by the Condemnation, except that Landlord shall not be obligated
to repair any damage for which Tenant has been reimbursed by the condemning
authority. If the severance damages received by Landlord are not sufficient to
pay for such repair, Landlord shall have the right to either terminate this
Lease or make such repair at Landlord's expense.

contest any tax, assessment or charge on the Property.

     (a) To establish reasonable rules and regulations for the use of the common
areas (including without limitation the delivery of goods and the disposal of
trash);

     (b) To use or permit the use of such common areas by others to whom
landlord may grant or may have granted such rights in such manner as Landlord
may from time to time designate;

     (c) To close all or any portion of the common areas to make repairs or

otherwise;

     (e) To enter into operating agreements with respect to the common areas;
and

     (f) To do such other acts in and to the common areas as in Landlord's
judgment may be desirable.

     Landlord grants Tenant and Tenant's customers and invitees the non-
exclusive right to use the common areas, in common with others to whom the
Landlord has granted or will grant a similar right.

     Tenant will pay Landlord as a common area charge Tenant's proportionate
share of all costs paid or incurred by Landlord in operating and maintaining the
common areas, including without limitation: cleaning, window washing,
landscaping, lighting, heating, air conditioning, maintaining, painting,
repairing, and replacing (except to the extent proceeds of insurance or

common areas; and rent paid for leasing equipment used in operating and
maintaining the common areas; cost not to exceed $16.85 per month for the term

cost incurred by Landlord by a fraction, the numerator of which is the number of
square feet of floor area within the premises and the denominator of which is
the total number of square feet of floor area leased within all the buildings in
the Development Complex in the amount set forth in Section 1.12 (b)(iv) of this
lease.

any part thereof, including without limitation, a reassessment of the value
thereof, the lease of the Premises by Tenant shall be included with the term

by such party, a waiver of subrogation rights as to such other party as well as
to GUARDIAN MANAGEMENT CO.

     Landlord shall have the right to sell, transfer, or assign its interest
hereunder or any part thereof without the prior consent of Tenant. After such

                             ---------------------

     Tenant agrees within fifteen (15) days following request by Landlord to
execute and deliver to Landlord any documents (including an estoppel
certificate) (a) certifying that this Lease is unmodified and in full force and
effect, or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect and the date to
which the rent and other charges are paid in advance, if any, and (b)
acknowledging that there are no, to Tenant's knowledge, accrued defaults on the
part of the Landlord hereunder, or so specifying such defaults, if any, are
claimed, evidencing the status of the Lease as may be required either by a
lender making a loan to Landlord to be secured by a deed of trust of mortgage
covering the premises or a purchaser of the Premises from Landlord, and (c) to
deliver to Landlord current financial statements of Tenant (with an opinion by a
certified public accountant, if available), including a balance sheet and a
profit and loss statement for at least two (2) years, all prepared in accordance
with generally accepted accounting principles consistently applied.  Tenant's
failure to deliver an estoppel certificate within such time shall be conclusive
upon Tenant (i) that this Lease is in full force and effect,, without
modification except as may be represented by Landlord, (ii) that to Tenant's
knowledge, there are no uncured defaults in Landlord's performance, and (iii)
that no rent has been paid in advance except as set forth in this lease.

                                ---------------

     In the event Tenant shall default under the terms of the Lease Agreement,
and shall remain in default for a period of five (5) days after the date due,
and such rent or other sum of money is placed in the hands of an attorney for
collection is collected through suits, bankruptcy or other judicial proceeding,
then Tenant agrees to pay to Landlord all reasonable attorney's fees and costs
incurred by Landlord due to such nonpayment in a sum not less than fifteen
percent (15%) of the amount of rent or other sums of money then owed by Tenant
to Landlord as attorney's fees.  The mere placing of any past due rents or other
past due sums of money in the hands of an attorney for collection, shall
obligate the Tenant to pay such attorney's fees, and it shall not be necessary
that same be collected through any suit or other judicial proceedings.  Should
Tenant remain in possession of the Premises past the term of this Lease after
request to vacate by Landlord, Tenant agrees to pay Landlord's reasonable
attorney's fees.

due.

        (ii)  Abandonment and vacation of the Premises.  Failure to occupy and

21.02.  Notices:
        ------- 

        Notices given under this Paragraph shall specify the alleged default and
shall demand that Tenant perform the provisions of this Lease or pay the rent
that is in arrears, as the case may be, within the applicable time period, or
quit the Premises.  No such notice shall be deemed a forfeiture or a termination
of this Lease unless Landlord so elects in the notice.

        Any notice, request, approval, consent or other communication required
or contemplated by this Lease must be in writing, and may, unless otherwise in
this Lease expressly provided, be given or served by depositing the same in the
United States Postal Service, post-paid and certified and addressed to the party
to be notified, with return receipt requested, or by delivering the same in
person to such party (or, in the case of a corporate party, to an officer of
such party), or by prepaid telegram, when appropriate, addressed to the party to
be notified.


21.03.  Landlord's Remedies:
        ------------------- 

        Landlord shall have the following remedies if Tenant commits a default.
These remedies are not exclusive; however, they are cumulative and in addition
to any remedies now or later allowed by law or in equity.


        (i) Landlord's Election to continue the Lease, in Full Force and Effect:
Landlord can continue this Lease in full force and effect, and the Lease will
continue in effect, and Landlord shall have the right to collect rent when due.
During the period Tenant is in default, Landlord can enter the Premises and
relet it, or any part of it, to third parties for Tenant's account. Tenant shall
be liable immediately to Landlord for all costs Landlord incurs in reletting the
Premises, including without limitation, brokers' commissions, expenses of
remodeling the Premises required by the reletting, and the costs.  Reletting can
be for a period shorter or longer than the remaining term of this Lease.  Tenant
shall pay Landlord the rent due under this Lease on the dates the rent is due,
less the rent Landlord receives from any reletting.  No act by Landlord allowed
by this Paragraph, subparagraph C(i) shall terminate this Lease unless Landlord
notifies Tenant in writing that Landlord elects to terminate this Lease.  If
Landlord elects to relet the Premises as provided in this Paragraph,
subparagraph C(i), rent that Landlord receives from reletting shall be applied
in the following order of priority: (a) to any indebtedness from Tenant to
Landlord other than rent due from Tenant; (b) to all costs, including those for
maintenance, incurred by Landlord in reletting; and (c) to rent due and unpaid
under this Lease.  After deducting the payments referred to in this Paragraph,
subparagraph C(i) any sum remaining from the rent Landlord receives from
reletting shall be held by Landlord and applied in payment of future rent as
rent becomes due under this Lease.  In no event shall Tenant be entitled to any
excess rent received by Landlord.  If, on the date rent is due under this Lease
the rent received from the reletting is less than the rent due on' that date,
Tenant shall pay to Landlord, in addition to the remaining rent due, all costs
Landlord incurred in reletting that remain after applying the rent received from
the reletting as provided in this Paragraph, subparagraph C(i).

                                       14
<PAGE>
 
     (ii) Landlord's Election to Terminate: Landlord can terminate this Lease
Agreement.  No act by Landlord or other than giving express written notice of
Landlord's election to terminate the Lease to Tenant shall terminate this Lease.
Acts of maintenance, efforts to relet the Premises, or the appointment of a
receiver on Landlord's initiative to protect landlord's interest under this
Lease shall not constitute a termination of Tenant's right to possession.  On
termination, Landlord has the right to recover from Tenant the sum of the
following:


        (a) The excess, if any, of (1) the present value of all amounts which
would have become due under this Lease for the remainder of the Term, over (2)
the present value of any net amounts which Tenant establishes Landlord may not
reasonably expect to recover by reletting the Premises for the remainder of the
Term, taking into consideration the cost of such reletting, including
remodeling, the availability of acceptable Tenants and other market conditions
affecting leasing.  Such present value shall be calculated at a discount rate
which is the lesser of (i) the maximum rate allowed by law, or (ii) the rate
commonly called the prime or base rate announced by Texas Commerce Bank, N.A.
(or its successor, but if there is not a successor which announces a prime or
base rate, then by a national bank selected by Landlord) at the time of such
termination.

        (b) All legal expenses, including attorneys' fees, experts' fees,
witness fees, court costs, and other costs incurred in preparation of any
litigation or consultations with counsel, incurred by Landlord in affecting re-
entry or repossession of the Premises and in prosecuting any related action
against Tenant;

        (c) All costs incurred by Landlord in restoring the Premises to good
order and condition;

        (d) All costs incurred by Landlord in altering or preparing the
Premises for reletting;

        (e) All commissions incurred by Landlord in reletting the Premises;
and

        (f) Any other amount, and court costs necessary to compensate Landlord
for all detriment proximately caused by Tenant's default.


     (iii) Appointment of Receiver: If Tenant is in default of this
Lease, Landlord shall have the right to have a Receiver appointed to collect
rent and conduct Tenants business.  Neither the filing of a petition for the
appointment of a Receiver nor the appointment itself shall constitute an
election by Landlord to terminate this Lease.

     (iv) Right to Regain Possession: Landlord may enter upon and take
possession of the Premises, by picking, altering or changing of the locks, if
necessary, and lock out, expel or remove Tenant and any other person who may be
occupying all or a part of the Premises without being liable for any claim for
damages, and relet the Premises on behalf of Tenant and receive 

                                       15
<PAGE>
 
directly the rent by reason of such reletting. Exercise by Landlord of any one
or more remedies hereunder granted or otherwise available shall not be deemed to
be an acceptance of surrender of the Premises by Tenant and no such alteration
of locks or other security devices and no removal or exercise of dominion by
Landlord over the property of Tenant or others at the Premises shall be deemed
unauthorized or constitute a conversion, Tenant hereby consenting after default
to the aforesaid exercise of dominion over Tenants property within the Premises.
All claims for damages by reason of such re-entry and/or repossession and/or
alteration of locks or other security devices are hereby waived as are all
claims for damages by reason of any distress warrant, forcible detainer
proceeding, sequestration proceeding or other legal process. Tenant agrees that
any re-entry by Landlord may be pursuant to judgment obtained in forcible
detainer proceedings or other legal proceedings or without the necessity of any
legal proceedings as Landlord may elect and Landlord shall not be liable in
trespass or otherwise, Landlord shall have no duty to give a key to the Leased
Premises to Tenant except and until the default and payments due by Tenant by
reason thereof have been fully satisfied.

     In the event that Landlord shall have taken possession of the Premises
pursuant to authority granted herein.  then Landlord shall have the right to
keep in place and use all of the furniture, fixtures and equipment at the
Premises including that which is owned by or leased to Tenant at all times prior
to any foreclosure thereon by Landlord or repossession thereof by any Lessor
thereof or third party having a lien thereof.  Landlord shall also have the
right to remove from the Premises (without the necessity of obtaining a distress
warrant, writ of sequestration or other legal process) all or any portion of the
furniture, fixtures, equipment, records and other properties located thereon and
to place same in storage at the Premises within the county in which the Premises
is located and in such event Tenant shall be liable to Landlord for costs
incurred by Landlord in connection with such removal and storage.  Landlord
shall also have the right to relinquish possession of all or a portion of the
furniture, fixtures, equipment and other property to any person ("Claimant")
claiming to be entitled to possession thereof who presents to Landlord a copy of
any instrument represented to Landlord by Claimant to have been executed by
Tenant (or any predecessor of Tenant) granting Claimant the right under various
circumstances to take possession of such furniture, fixtures, equipment or other
property without the necessity on the part of Landlord to inquire into the
authenticity of said instruments copy of Tenant's or Tenants predecessor's
signature thereon and without the necessity of Landlord making any nature of
investigation or inquiry as to the validity of the factual or legal basis upon
which the Claimant purports to act; and Tenant agrees to indemnify and hold
harmless Landlord from all costs, expenses, loss, damage and liability incident
to Landlord's relinquishment of possession of all or any portion of such
furniture, fixtures, equipment or other property of Claimant.  The rights of
Landlord herein stated shall be in addition to any and all other rights which
Landlord has or may hereinafter have at law or in equity; and Tenant stipulates
and agrees that the rights herein granted Landlord are commercially reasonable.
If, after the payment of all amounts due claimant by Tenant, there remains any
movable equipment, furniture and/or personal property of Tenant which is not
removed by Tenant before the expiration of such time period, then the parties
agree that such property shall be in all things conclusively determined 

                                       16
<PAGE>
 
and established to be abandoned by Tenant in favor of Landlord and shall at once
become the property of Landlord upon such abandonment. In no event will Landlord
be responsible for the removal, custody or disposition for such abandoned
property of Tenant or, in any way, be held liable for conversion or any action
in relation to the removal, retention and disposition of such personal property,
all such claims of Tenant being waived by Tenant herein, and Landlord will be
free to dispose of such property in its sole and absolute discretion under the
terms and conditions acceptable to it.

     (v) Landlord's Right to Cure Tenant's Default:  Landlord, at any time after
Tenant commits a default, can cure the default at Tenant's cost.  If Landlord,
at any time by reason of Tenants default, pays any sum or does any act that
requires the payment of any sum, the sum paid by the Landlord shall be due
immediately from Tenant to Landlord at the time the sum is paid, and if paid at
a later date, shall bear interest at the maximum legal rate an individual is
permitted by law to charge from the date the sum is paid by Landlord until
Landlord is reimbursed by Tenant.  The sum, together with interest on it, shall
be additional rent.

     (vi) Interest on Unpaid Rent:  Rent not paid when due shall bear interest
from the date due until paid at the highest legal rate of interest per annum.

     (vii) Late Charge: Tenant acknowledges that late payment by Tenant to
Landlord of' rent will cause Landlord to incur costs not contemplated by this
Lease, the exact amount of such costs being extremely difficult and
impracticable to fix. Such costs include, without limitation, Processing and
accounting charges, and late charges that may be imposed on Landlord by the
terms of any encumbrances not secured by an encumbrance covering the Premises.
Therefore, if any installment of rent due from Tenant is not received by
Landlord within five (5) days of when due, or any check tendered to Landlord by
Tenant is returned to Landlord as uncollectible, Tenant shall pay to Landlord
the applicable charges set forth in Section 1.13, hereof. The parties agree that
this late charge represents a fair and reasonable estimate of the costs that
Landlord will incur by reason of late payment of Tenant. Acceptance of any late
charge shall not constitute a waiver of Tenant's default with respect to the
overdue amount, or prevent Landlord from exercising any of the other rights and
remedies available to Landlord.


     (viii) Non-Waiver: No covenant, term or condition or the breach thereof
shall be deemed waived, except by written consent of the party against whom the
waiver is claimed, and any waiver or the breach of any covenant, term or
condition shall not be deemed to be a waiver of any preceding or succeeding
breach of the same or any other covenant, term or condition of this Lease.
Acceptance by Landlord of any performance by Tenant after the time the same
shall have become due shall not constitute a waiver by Landlord of the breach or
default of any covenant, term or condition of the Lease unless otherwise
expressly agreed to by Landlord in writing. No payment by Tenant or receipt by
Landlord of a lesser amount than the minimum monthly rent or any other amount
payable by Tenant and defined as "rent" in Paragraph 2, shall be deemed to be
other than on account of the earliest outstanding installment of any such

                                       17
<PAGE>
 
stipulated amount due. No endorsement or statement on any check or any letter
accompanying any check or payment shall be deemed an accord and satisfaction and
Landlord may accept such check or payment without prejudice to Landlord's rights
to recover the balance of any outstanding amounts then due and payable or past
due and in arrears under this Lease and without prejudice to any other remedy
provided in this Lease. Nothing in this Paragraph shall be deemed to affect
Landlord's rights to indemnification and other rights provided under this Lease
arising out of any act, omission, event or occurrence which took place prior to
the termination of the Lease whether a claim relating to such acts, omissions,
events or occurrences is made before or after the date of termination of this
Lease. The delivery of keys to any employee of landlord or its agents or
employees shall not operate as a termination of this Lease or a surrender of the
Premises.

     (ix) Right of Redemption:  Tenant hereby expressly waives any and all
rights of redemption granted by or under any present or future law in the event
of Tenant's eviction or dispossession pursuant to any default under this Lease
or in the event of Landlord's obtaining possession of the Premises by reason of
Tenant's violation of any of the covenants, conditions or agreements contained
herein.

     Should the premises be damaged or destroyed by fire, explosion, wind storm,

the Premises, Landlord shall, at Landlord's option exercisable by written notice
to Tenant within thirty (30) days after such damage or destruction, either
terminate this Lease effective as of the date of such damage or destruction, or
Landlord may proceed to repair and rebuild the damaged or destroyed premises
upon substantially the same plan as existed immediately prior to such damage or
destruction, provided, however, in any event, Landlord shall not be required to
initiate any such repair until receipt of insurance proceeds covering such
damages nor shall Landlord be obligated to expend any funds in excess of such
insurance proceeds in completing such restoration.  In the event that the
business of Tenant is materially impaired due to such damage, the monthly
rentals payable hereunder shall be proportionately abated to the extent that the
Premises are not usable from the occurrence of such damage until the premises

     Tenant shall not have the power to commit any act or make any contract that
may create or be the foundation of any lien upon the present or other estate of

thereon; and should any such lien be created or filed, Tenant, at its own cost

                                  ------------

     In the event the Tenant shall hold over the Premises with the consent of
Landlord after the expiration or termination of the primary or extended term of
this Lease, such holding over shall not be deemed to operate as or constitute an
extension or renewal of this Lease, but the Tenant so holding over shall be
deemed to be Tenant from month-to-month during such holdover period at a
holdover rental rate of one hundred fifty percent (150%) of rent last charged
hereunder prior to the beginning of such holdover period, which month-to-month
tenancy may be terminated at the end of any month by Landlord or Tenant upon (4)
weeks' advance written notice of the intent to vacate prior to the expiration of
the lease or any extension thereof.  Neither 

                                       20

the giving of such notice to vacate nor the acceptance of such notice or
holdover period shall in any way waive any rights of Landlord herein or be
deemed a consent by Landlord to holdover.

                                LANDLORD'S LIEN
                                ---------------

     Subject to any applicable state and federal laws, in addition to the
statutory Landlord's lien, Landlord shall have, at all times, a valid security
interest to secure payment of all rentals and other sums of money becoming due
hereunder from Tenant, and to secure payment of any damages or loss which
Landlord may suffer by reason of the breach by Tenant of any covenant agreement
or condition captained herein, upon al goods, wares, equipment, fixtures,
furniture, improvements, and other personal property of Tenant present of which
may hereinafter be situated on the Premises, and all proceeds therefrom, and
such property shall not be removed therefrom, with the consent of Landlord until
all arrearages in rent as well as any and all other sums of money due to
Landlord hereunder shall first have been paid and discharged and all the
covenant agreement, and conditions hereof have been fully complied with and
performed by Tenant.  Upon the occurrence of an event of default by Tenant,
Landlord may, in addition to any other remedies provided herein, to the extent
allowed by law, enter upon the Premises and take possession of any and all
goods, wares, equipment, fixtures, furniture, improvements, and other personal
property of Tenant situated on the Premises, without liability for trespass or
conversion, and sell the same at public or private sale, after giving Tenant
reasonable notice of the time and place of any public sale or of the time after
which any private sale is to be made, at which sale, the Landlord or its assigns
may purchase unless otherwise prohibited by law.  Unless otherwise provided by
law, and without intending to exclude any other manner of giving Tenant
reasonable notice, the requirement of reasonable notice shall be met if such
notice is given at least five (5) days before the time of sale.  The proceeds
from any such disposition, less any and all expenses connected with the taking
of possession, holding, and selling of the property (including reasonable
attorney's fees and other expenses), shall be applied as a credit against the
indebtedness secured by the security interest granted in this section.  Any
surplus shall be paid to Tenant or as otherwise required by law; and the Tenant
shall pay any deficiencies forthwith.  Upon request by Landlord, Tenant agrees
to execute and delivery to Landlord a financing statement in form sufficient to
perfect the security interest of Landlord in the aforementioned property and
proceeds thereof under the provisions of the Uniform Commercial Code in force in
the State of Texas.  Tenant does hereby appoint Landlord its attorney-in-fact to
execute in Tenants name and in its place and stead any instrument necessary to
effectuate the terms of this Landlord's Lien including any Financing Statement
in connection therewith.  The statutory lien for rent is not hereby waived, the
security interest herein granted being in addition and supplementary thereto.

           -----------------------------------
parties claiming under them mutually release and discharge each other from all
claims and liabilities arising from or caused by any casualty or hazard covered
by valid and collectible insurance on the Premises, and waive any right of
subrogation which might otherwise exist in or accrue to any person on account
thereof; provided that such release shall not operate in any case where the
effect is to invalidate such insurance coverage. This release shall apply even
if the loss or damage shall be caused by the fault or negligence of a party
hereto or for any person for which such party is responsible.

     16.4. WAIVER. Landlord, its agent or employees shall not be liable, and
           ------

     17.   RIGHT OF ENTRY. Landlord, its agents and employees, shall have the
           --------------
right to enter the Premises from time to time at reasonable times to examine the
Premises, to show them to prospective purchasers and other persons and to make
such repairs, alterations, improvements or additions as Landlord deems
desirable. Rent shall in no wise abate while any such repairs, alterations,
improvements or additions are being made. During the last six (6) months of the
term of this Lease, Landlord may exhibit the Premises to prospective Tenants and
maintain upon the Premises notices deemed advisable by Landlord. In addition,
during any apparent emergency, Landlord, its agents and employees, may enter the

or liability whatsoever for any care, maintenance or repair except as otherwise

way connected with Tenant's use, occupancy, management or control of the
Premises or Tenant's operations, conduct or activities in the Center. Tenant
authorizes Landlord (although expressly recognizing that Landlord is under no
obligation to do so) to defend, settle or compromise any claims, demands, suits,
proceedings or the like which may represent an indemnifiable obligation of
Tenant hereunder. Such action or inaction by Landlord shall in no way effect
Tenant's indemnity obligations as provided herein.

     19.   SUBORDINATION AND ATTORNMENT. Tenant accepts this Lease subject and
           ----------------------------
subordinate to any mortgage, deed of trust, or other lien presently existing on
the Premises or the Center as a whole, and to any renewals and extensions
thereof; but, Tenant agrees that any such mortgagee shall have the right at any
time to subordinate such mortgage, deed of trust, or other lien to this Lease.
Landlord is hereby irrevocably vested with full power and authority to
subordinate this Lease to any mortgage, deed of trust, or other lien hereafter
placed on the Premises or the Center as a whole and Tenant agrees on demand to
execute such further instruments subordinating 

                                                                               7
<PAGE>
 
this Lease as Landlord may request, provided such subordination shall be on the
express condition that this Lease shall be recognized by the mortgagee and that
the rights of Tenant shall remain in full force and effect during the term of
this Lease so long as Tenant shall continue to perform all of the covenants and
conditions of this Lease. Tenant covenants and agrees that upon foreclosure of
any deed of trust, mortgage or other instrument of security and the sale of the
Premises or Center pursuant to any such document, to attorn to any purchaser at
such a sale and to recognize such purchaser as the Landlord under this Lease.
The agreement of Tenant to attorn to any purchaser pursuant to such a
foreclosure sale or trustee's sale in the preceding sentence shall survive any
such sale.

     20.   ESTOPPEL CERTIFICATE. Tenant shall at any time, upon the request of
           --------------------
Landlord, execute, acknowledge and deliver to Landlord a statement in writing
certifying that this Lease is unmodified and in full force and effect (or if
modified stating the nature of such modification and certifying that the Lease
as modified is in full effect), the dates to which the rent and other charges
are paid in advance, if any, and acknowledging that there are not, to Tenant's
knowledge, any uncured defaults on the part of Landlord hereunder, or specifying
such defaults if any are claimed. The parties agree that any such statement may
be relied upon by any prospective purchaser or encumbrance of all or any portion
of the Center. Tenant's failure to deliver such statement within ten (10) days
after Landlord's request for the same, shall be conclusive upon Tenant that: (i)
this Lease is in full force and effect; (ii) there are no uncured defaults in
Landlord's performance and (iii) not more than one month's rent or other charge
has been pain in advance.

     21.   DAMAGE AND DESTRUCTION. If the Premises are hereafter damaged or
           ----------------------
destroyed or rendered partially untenantable for their accustomed use by fire or
other casualty insured under the coverage which Landlord is obligated to carry
hereunder, Landlord shall promptly repair the same to substantially the
condition which they were in immediately prior to the happenings or such
casualty (excluding stock in trade, fixtures furniture, furnishings, carpeting,
floor covering, wall covering, drapes and equipment). From the date of such
casualty, until the Premises are so repaired and restored, the monthly rent
payments hereunder shall abate in such proportion as the part of said Premises
thus destroyed or rendered untenantable bears in the total Premises; provided
however, that Landlord shall not be obligated to repair and restore if such
casualty is caused directly or indirectly by the negligence of Tenant, its
agents or employees; and provided further, that Landlord shall not be obligated
to expend for such repair or restoration an amount in excess of the insurance
proceeds recovered as a result of such damage. Notwithstanding that above, if
the Premises are wholly or partially damaged, destroyed or rendered untenantable
for their accustomed use by fire or other casualty then Landlord shall have the
right to terminate this Lease effective as of the date of such casualty by
giving Tenant, within sixty (60) days after the happening of such casualty,
written notice of such a termination if such notice is given, this Lease shall
terminate and Landlord shall promptly repay to Tenant any rent paid in advance
which was not earned at the date of such a casualty. If said notice is not given
and Landlord is required or elects to repair or restore the Premises as herein
provided, then Tenant shall promptly repair or replace its stock in trade
fixtures, furnishings, furniture, carpeting, wall covering, floor covering,
drapes and equipment to the same condition as they were in immediately prior to
the casualty and, if Tenant has closed its business, Tenant shall promptly
reopen for business upon the completion of such repairs.

     22.   EMINENT DOMAIN.
           --------------

     22.1. EMINENT DOMAIN. If 10% or more of the Premises or 15% or more of the
           --------------
Center shall be acquired or condemned by right of eminent domain for any public
or quasi-public use or purpose then Landlord at its election may terminate this
Lease by giving notice to Tenant of its election, and in such event, rentals
shall be apportioned and adjusted as of the date of termination. If the Lease
shall not be terminated as aforesaid, then it shall continue in full force and
effect, and Landlord shall within a reasonable time after possession is
physically taken (subject to delays due to shortage of labor, materials or
equipment, labor difficulties, breakdown of equipment, governmental
restrictions, fires, other casualties or other causes beyond the reasonable
control of Landlord) to repair or rebuild what remains of the Premises for
Tenant's occupancy, and a just proportion of the rent shall be abated, according
to the nature and extent of the injury to the Premises, until such repairs and
rebuilding are completed, and thereafter for the balance of the term of this
Lease.

     22.2. DAMAGES. Landlord reserves and Tenant assigns to Landlord, all rights
           -------
to damages on account of any taking or condemnation or any act of any public or
quasi-public authority for which damages are payable.

                                                                               8
<PAGE>
 
Tenant shall execute such instruments of assignment as Landlord requires, join
with Landlord in any action for the recovery of damages if requested by
Landlord, and turn over to Landlord any damages recovered in any proceeding. If
Tenant fails to execute instruments required by Landlord, or undertakes such
other steps as requested, Landlord shall be deemed the duly authorized
irrevocable agent and attorney-in-fact of Tenant to execute such instruments and
undertake such other steps on behalf of Tenant. However, Landlord does not
reserve any damages payable for trade fixtures installed by Tenant at its own
cost which are not part of the realty.

     23.   ASSIGNMENT AND SUBLETTING. Tenant shall not assign this Lease or any
           -------------------------
interest therein, whether voluntarily, by operation of law, or otherwise, and
shall not sublet the Premises or any part thereof except by written permission
and consent of Landlord being first had and obtained. Consent of Landlord to any
such assignment or subletting shall not be unreasonably withheld if: (i) at the
time of such assignment or subletting Tenant is not in default in the
performance and observance of any of the covenants and conditions of this Lease;
(ii) the assignee or subtenant of Tenant shall expressly assume in writing all
of Tenant's obligations hereunder; (iii) Tenant shall provide proof to Landlord
that the assignee or subtenant has a financial condition which is satisfactory
to Landlord and Landlord's lender; (iv) the Premises continue to be used solely
for the purpose set forth in Paragraph 9.1; (v) in Landlord's opinion the
proposed operation of the prospective assignee or subleasee will generate
percentage rental at Lease equal that currently paid by Tenant; (vi) the
assignee or subtenant is, in Landlord's opinion, capable of operating such
business; and (vii) the assignee or subtenant agrees to pay such additional
rent, if any, as Landlord desires to charge. In connection with any such
assignment or sublease, Tenant or the assignee or subtenant of Tenant shall pay
to Landlord any legal and administrative costs incurred by Landlord in approving
such assignment or subletting, not to exceed $1,000.00. Any such assignment or
sublease, even with the approval of Landlord, shall not relieve Tenant from
liability for payment of all forms of rental and other charges herein provided
or from the obligations to keep and be bound by the terms, conditions and
covenants of this Lease. The acceptance of rent from any other person shall not
be deemed to be a waiver of any of the provisions of this Lease or a consent to
the assignment or subletting of the premises. Consent to any assignment or
subletting shall not be deemed a Consent to any future assignment or subletting.
Any merger, consolidation or transfer of corporate shares of Tenant, if Tenant
is a corporation, so as to result in a change in the present voting control of
the Tenant by the person or persons owning a majority of said corporate shares
on the date of this Lease, shall constitute an assignment and be subject to the
conditions of this Paragraph. If Tenant is a general partnership having one or
more corporations as partners, the provisions of the proceeding sentence shall
apply to each of such corporations as if such corporation alone had been the
Tenant hereunder. Moreover, in the event that the rental due and payable by a
sublessee or a combination of the rental payable under such sublease plus any
bonus or other consideration therefore or incident thereto exceeds the rent
payable under this Lease or if with respect to a permitted assignment, permitted
licenses or other transfer by Tenant permitted by Landlord, the consideration
payable to Tenant by the assignee, licensee or other transferee exceeds the
rental payable under this Lease, then Tenant shall be bound and obligated to pay
Landlord all such excess rental and other excess consideration within ten (10)
days following receipt thereof by Tenant from such sublessee, assignee, licensee
or other transferee as the case may be. Finally in the event of any assignment
or subletting it is understood and agreed that all rentals paid to Tenant by an
assignee or sublessee shall be received by Tenant in trust for Landlord, to be
forwarded immediately to Landlord without reduction of any kind, and upon
election by Landlord such rentals shall be paid directly to Landlord.

     24.   LANDLORD'S PERFORMANCE FOR ACCOUNT OF TENANT. If the Tenant shall
           --------------------------------------------
continue in default in the performance of any of the covenants or agreements
herein contained after the time limit for the curing thereof, then Landlord may
perform the same for the account of Tenant. Any amount paid or expense or
liability incurred by Landlord in the performance of any such matter for the
account of Tenant shall be deemed to be additional rent and the same (together
with interest thereon at the rate of eighteen percent (18%) per year from the
date upon which any such expense shall have been incurred) may, at the option of
Landlord, be added to any rent then due, or thereafter falling due hereunder.

     25.   DEFAULT BY TENANT.

<PAGE>
 
Lease for more than ten (10) days after written notice of such failure; (c)
Landlord determining that Tenant has submitted any false report required to be
furnished hereunder; (d) if Tenant shall do anything upon or in connection with

indirectly interferes in any way with or results in a work stoppage in
connection with construction of any part of the Center or any other Tenant's
space; (e) Tenant shall become bankrupt or insolvent, or file or have filed
against it a petition in bankruptcy or for reorganization or arrangement or for
the appointment of a receiver or trustee of all or a portion of Tenant's
property, or Tenant makes an assignment for the benefit of creditors; (f) if
Tenant abandons, vacates or does not do business in the Premises for ten (10)
days; (g) this Lease, Tenant's interest herein or in the Premises, any
improvements thereon, or any property of Tenant is executed upon or attached; or
(h) the Premises comes into the hands of any person other than expressly

     25.2. LANDLORD'S REMEDIES. Upon the occurrence of any event of default
           -------------------

same being hereby waived by Tenant, and in addition to all other rights or
remedies Landlord may have for such default, shall have the right to pursue any
one or more of the following remedies:

           (a)  Thereupon or any time thereafter, change the locks of the
Premises in accordance with Paragraph 25.3:

           (b)  Terminate this Lease in which event Tenant shall immediately
surrender the Premises to Landlord and if Tenant fails to do so, Landlord may,
without prejudice to any other remedy which it may have for possession or
arrearage in rent, enter upon and take possession of the Premises and expel or
remove Tenant and any other person who may be occupying said Premises or any
part thereof, by force if necessary, without notice or the need to resort to
legal process and without being deemed guilty of trespass or becoming liable for
any loss or damage occasioned thereby; and Tenant agrees to pay to Landlord on
demand the amount of all loss and damages which Landlord may suffer by reason of
such termination, whether through inability to relet the Premises on
satisfactory terms or otherwise, including the loss of rental for the remainder
of the Lease term;

           (c)  Without terminating this Lease, enter upon and take possession
of the Premises, and expel or remove Tenant and any other person who may be
occupying said Premises, or any part thereof, by force if necessary, without
notice or the need to resort to legal process and without being deemed guilty of
trespass or becoming liable for any loss or damage occasioned thereby. Landlord
may make such alternations and repairs as it deems advisable to relet the
Premises and relet the Premises or any part thereof for such term or terms
(which may extend beyond the term of this Lease) and at such rentals and upon
such other terms and conditions as Landlord in its sole discretion deems
advisable. Upon each such reletting all rentals received by Landlord therefrom
shall be applied first to any indebtedness other than rent due hereunder from
Tenant to Landlord; second, to pay any costs and expenses of reletting including
brokers and attorney's fees and costs of alterations and repairs; third, to rent
due hereunder; and fourth, the residue, if any, shall be held by Landlord and
applied in payment of future rent as it becomes due hereunder. If rentals
received from such reletting during any month are less than that to be paid
during that month by Tenant hereunder, Tenant shall immediately pay any such
deficiency to Landlord. No reentry or taking possession of the Premises by
Landlord shall be construed as an election to terminate this Lease unless a
written notice of such termination is given by Landlord to Tenant.
Notwithstanding any such reletting or reentry or taking possession, without
termination, Landlord may at any time thereafter terminate this Lease for any
prior breach or default. Pursuit of any of the foregoing remedies shall not
preclude pursuit of any of the other remedies herein provided or any other
remedy provided by law, nor shall the pursuit of any remedy herein provided
constitute a forfeiture or waiver of any rent due to Landlord hereunder or of
any damages accruing to Landlord. If Landlord terminates this Lease for any
breach or default by Tenant, in addition to all other remedies provided by law
to which Landlord may be entitled, Landlord may recover from Tenant all damages
incurred by reason of such breach or default, including, without limitation, all
costs of retaking the Premises and the total rent and charges reserved in this
Lease for the remainder of the term of this Lease, all of which shall be
immediately due and payable by Tenant to Landlord.

     25.3. LOCKOUT PROVISIONS. Upon the occurrence of an event of default under
           ------------------
the Lease, Landlord shall be entitled to change the locks of the Premises.
Tenant agrees that entry may be gained for that purpose through use

                                                                              10
<PAGE>
 
of a duplicate or master key or any other peaceable means, that same may be
conducted out of the presence of Tenant if Landlord so elects, that no notice
shall be required to be posted by the Landlord on any door to the Premises (or
elsewhere) disclosing the reason for such action or any other information and
that Landlord shall not be obligated to provide a key to the changed lock to
Tenant unless Tenant shall have first:

               (1)  Brought current all payments due to Landlord under this
Lease; provided, however, that if Landlord has theretofore formally and
permanently repossessed the Premises or has terminated this Lease, then Landlord
shall be under no obligation to provide a key to the new lock(s) to Tenant
regardless of Tenant's payment of past-due rent or other past-due amounts,
damages, or any other payment or amounts of any nature or kind whatsoever.

               (2)  Fully cured and remedied to Landlord's satisfaction all
other defaults of Tenant under this Lease (but if such defaults are not subject
to cure, such as early abandonment or vacation of the Premises, then Landlord
shall not be obligated to provide the new key to Tenant under any
circumstances); and

               (3)  Given Landlord security and assurances satisfactory to
Landlord that Tenant intends to and is able to meet and comply with its future
obligations under this Lease, both monetary and non monetary.

               Landlord will, upon written request by Tenant, at Landlord's
convenience and upon Tenant's execution and delivery of such waivers and
indemnifications as Landlord may require, at Landlords option either (i) escort
Tenant or its specifically authorized employees or agents to the Premises to
retrieve personal belongings and effects of Tenant's employees (as opposed to
property which is an asset of Tenant or any guarantor), and property of Tenant
that is not subject to the Landlord's liens and security interests described
herein or (ii) obtain from Tenant a list of such property described (i) above,
the arrange for such items to be removed from the Premises and made available to
Tenant at such place and at such time in or about the Premises or the Center as
Landlord may designate; provided, however, that if Landlord elects option (ii),
then Tenant shall be required to pay in cash, in advance to Landlord (a) the
estimated costs that Landlord will incur in removing such property from the
Premises and making same available to Tenant at the stipulated location, and (b)
all moving and/or storage charges theretofore are to be incurred by Landlord
with respect to such property. The provisions of this Paragraph 25.3 are
intended to override and supersede any conflicting provisions of the Texas
Property Code (including, without limitation, Chapter 93 thereof, and any
amendments or successor statutes thereto), and of any other law, to the maximum
extent permitted by applicable law.

         26.   LANDLORD'S LIEN. To secure the performance of Tenant's obligation
               ---------------
under this Lease, Tenant, as Debtor, and referred to in this Paragraph as
"Debtor", hereby grants to Landlord, as "Secured Party", a security interest in
and an express contractual lien upon all of Debtors equipment, furniture,
furnishings, appliances, goods, trade fixtures, inventory, chattels, and other
personal property of Debtor which is now on the Premises or which is placed on
the Premises at some later date, and all proceeds from such items. This property
shall not be removed from the Premises without the consent of the secured party
under this Lease, until this Lease has been paid and discharged, and all the
covenants, agreements, and conditions of this lease have been fully complied
with and performed by Debtor. Secured Party is authorized and Debtor hereby
irrevocably and throughout the term of this Lease (and any extensions or
renewals thereof) appoints Secured Party as its attorney-in-fact to prepare and
file financing statements signed only by Secured Party as attorney-in-fact on
behalf of debtor covering the security described above; moreover, Debtor agrees
to sign the same upon request. Notwithstanding the foregoing, secured party is
hereby authorized to file a duplicate original or Xerox copy of this Lease as a
financing statement located as appropriate. Upon default under this Lease by
Debtor, as defined in Paragraph 25.1 hereof, any or all of debtors obligations
to secured party, secured hereby shall, at Secured Party's option, be
immediately due and payable without notice or demand. In addition to all rights
or remedies of Secured Party under this Lease and the law, including the right
to a judicial or non-judicial foreclosure, Secured Party shall have all the
rights and remedies of a secured party under the uniform commercial Code as
enacted in the State of Texas. This security agreement and the security interest
hereby created shall survive the termination of this Lease if such termination
results from debtor's default. The above-described security interest and lien
are in addition to and cumulative of the Landlord's lien provided by the laws of
the State of Texas.

                                                                              11

         27.   WAIVER OF RIGHTS OF REDEMPTION. To the extent permitted by law,
               ------------------------------
Tenant waives any and all rights of redemption granted by or under any present
or future laws if Tenant is evicted or dispossessed for any cause, or if
Landlord obtains possession of the Premises due to Tenant's default hereunder or
otherwise.

         28.   DEFAULT BY LANDLORD. Landlord shall in no event be charged with
               -------------------
default in any of its obligations hereunder unless and until Landlord shall have
failed to perform such obligations within thirty (30) days (or such additional
time as is reasonably required to correct any such default) after written notice
to Landlord by Tenant, specifically describing such failure.

         29.   APPLICATION OF PAYMENT RECEIVED FROM TENANT. Landlord shall have
               -------------------------------------------
the right to apply any payments made by Tenant to the satisfaction of any debt
or obligation of Tenant to Landlord according to Landlord's sole discretion and
regardless of the instructions of Tenant as to application of any such sum,
whether such instructions be endorsed upon Tenant check or otherwise, unless
otherwise agreed upon by both parties in writing. The acceptance by Landlord of
a check or checks drawn by a party other than Tenant shall not affect Tenant's
liability hereunder nor shall it be deemed an approval of any assignment of this
Lease by Tenant.

         30.   RESTRICTIVE COVENANT. During the term of this Lease Tenant shall
               --------------------
not directly or indirectly engage in any similar or competing business within a

office by notifying the other party of such change in accordance with this
Paragraph.

         32.   SALE OF PREMISES BY LANDLORD. In the event of any sale of the
               ----------------------------
Premises by Landlord, Landlord shall be and is hereby entirely freed and
relieved of all liability under any and all of its covenants and obligation
contained in or derived from this Lease arising out of any act, occurrence or
omission occurring after the consummation of such sale; and, the purchaser, at
such sale or any subsequent sale of the Premises shall be deemed, without any
further agreement between the parties or their successors in interest or between
the parties and any such purchaser, to have assumed and agreed to carry out any
and all of the covenants and obligations of the Landlord under this Lease.
Furthermore, in the event of a sale or conveyance by Landlord of the Premises,
or the property of which the Premises are a part, this Lease shall not be
affected by any such sale, and Tenant agrees to attorn to the purchaser thereof.

         33.   TITLE OF SHOPPING CENTER. Tenant shall use the name of the Center
               ------------------------
in all Tenant's advertising in connection with Tenant's business at the Premises
and for no other purpose, except with Landlord's prior written consent. Tenant
shall not have or acquire any interest in the name of the Center. Landlord
reserves the right to change the name, title or address of the Center or the
address of the Premises at any time, and Tenant waives all claims for damages
caused by such change.

                                                                              12

               ------
remedy of Landlord on any default of Tenant shall impair such a right or remedy
or be construed as a waiver. The receipt and acceptance by Landlord of
delinquent rent shall not constitute a waiver of any other default; it shall
constitute only a waiver of timely payment for the particular rent payment
involved. No act or conduct of Landlord, including, without limitation, the
acceptance of the keys to the Premises, shall constitute an acceptance of the
surrender of the Premises by Tenant before the expiration of the term. Only a
written notice from Landlord to tenant shall constitute acceptance of the
surrender of the Premises and accomplish a termination of the Lease. Landlords
consent to or approval of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to waiver or render unnecessary Landlords consent
to or approval of any subsequent act by Tenant. Any waiver by Landlord or any
default must be in writing and shall not be a waiver of any other default
concerning the same or any other provision of the Lease.

over or occupancy without Landlord's written consent), Tenant shall pay Landlord
for each day of such holding over, a sum equal to twice the monthly rent
applicable hereunder at the expiration of the term, prorated for the number of
days of such holding over. If Tenant holds over with or without Landlord's
written consent, Tenant shall occupy the Premises on a tenancy from month to
month and all other terms and provisions of this Lease shall be applicable to
such Period.

         35.2. SUCCESSORS. All rights and liabilities herein given or imposed
               ----------

consent of Landlord, which Landlord shall not unreasonably withhold, provided
Tenant demonstrates to Landlord's satisfaction that such Hazardous Material is
necessary or useful to Tenant's business and will be used, kept and stored in a
manner that complies with all laws regulating any such Hazardous Material so
brought upon or used or kept in or about the Premises.

Landlord or Tenant includes, without limitation, costs incurred in connection
with any investigation of site conditions or any clean-up, remedial, removal or
restoration work required by any federal, state, or local governmental agency or
political subdivision because of Hazardous Material present in the soil or
ground water on or under the Premises or Center. Without limiting the foregoing,
if the presence of any Hazardous Material on the Premises or Center caused or
permitted by Tenant results in any contamination of the Premises or Center.
Tenant shall promptly take all actions at its sole expense as are necessary to
return the Premises and/or Center to the condition existing prior to the
introduction of any such Hazardous Material to the Premises or Center, provided
that Landlord's approval of such actions shall first be obtained, Tenant further
agrees to defend Landlord, its agents, employees, and assigns in any
administrative or judicial proceeding commenced by private individuals or
governmental entities seeking recovery of damages for Personal injury or

damage, contribution, cost recovery, compensation loss or injury resulting from
any Hazardous Materials; (c) the discovery of any occurrence or condition on any
real property adjoining or in the vicinity of the Premises that could cause the
Premises to be classified in a manner which may support a claim under any
Environmental Law, and (d) the discovery of any occurrence or condition on the
Premises or any real property adjoining or in the vicinity of the Premises which
could subject Tenant or the Premises to any restrictions in ownership,

legal proceedings or other actions initiated in connection with any claims under
any Environmental Law and to have its reasonable attorney's fees paid by Tenant.

         37.5. ENVIRONMENTAL REVIEW. In the event reasonable evidence exists of

Premises, Landlord (by its officers, employees and agents) at any time and from
time to time may contract for the services of persons (the "Site Reviewers") to
perform environmental site assessments ("Site Assessments") on the Premises for

2.   LOANS: GENERAL TERMS
     --------------------

     2.1  Total Facility.
          -------------- 

               (a) Revolving Loans.  Lender agrees to make available for the
                   ---------------

     and conditions of this Agreement and shall consist of revolving advances
     based upon the Eligible Accounts and Eligible Inventory of the Borrowers in
     accordance with the following applicable advance rates and dollar
     limitations:

               An amount equal to the lesser of:
                                      --------- 

               (i)  the sum of

                              (A) eighty-five percent (85%) of the Eligible
                    Accounts of the Borrowers, except for the Eligible Accounts
                    of the Digital Division, plus seventy-five percent (75%) of
                    the Eligible Accounts of the Digital Division (subject, in
                        --------
                    each case, to adjustment based upon dilution as detailed
                    below) and

                              (B) the sum of (1) the lesser of (aa) thirty-five 
                                                     ------
                    percent (35%) of Eligible Demonstration Inventory and (bb)
                    One Million Five Hundred Thousand Dollars ($1,500,000) plus
                                                                           ----
                    (2) the lesser of (aa) fifty percent (50%) of all Eligible
                            ------
                    Inventory other than Eligible Demonstration Inventory and
                    (bb) Five Million Dollars ($5,000,000) less the aggregate
                                                           ----
                    outstanding amount of Loans made on the basis of Eligible
                    Demonstration Inventory, or

               (ii) Fifteen Million Dollars ($15,000,000).

               Lender may, in the exercise of its reasonable discretion, at any
     time and from time to time, increase or decrease the advance percentages to
     be applied to Eligible Accounts and Eligible Inventory which are contained
     in this Section.  In the event such percentages are decreased, such
     decrease shall become effective upon not less than ten (10) Business Days
     notice to Borrower, unless an Event of Default has occurred and is
     continuing or a material, negative audit finding has been made in which
     case such decrease shall be effective immediately, for the purpose of
     calculating the amount which Lender may be willing to advance, or allow to
     remain outstanding, against Eligible Accounts and Eligible Inventory.
<PAGE>
 
               Without limiting the generality of the preceding paragraph,
     Lender may adjust the advance rate for the Eligible Accounts of the
     Borrowers based upon the historical dilution of such Eligible Accounts in
     accordance with the matrix set forth below:

               Dilution                            Advance Rate
               --------                            ------------

               Less than 5%                             85%
               Greater than 5% but less than 
                or equal to 10%                         80%
               Greater than 10%                         75%

               Based upon Lender's understanding of the historical dilution
     rates of the Borrowers' Accounts, the initial advance rate for the Eligible
     Accounts of the Borrowers, except for the Digital Division, will be eighty-
     five percent (85%) and the initial advance rate for the Digital Division
     will be seventy-five percent (75%).  Lender will permit increases in the
     advance rate for the Eligible Accounts of the Digital Division (up to a
     maximum limit of 85%) provided that Lender's auditors verify that the
     dilution rate of the Accounts of the Digital Division during the preceding
     six-month period warrants such increase pursuant to the matrix set forth
     above.

               The Borrowers may permanently reduce the Total Facility (to an
     amount mutually acceptable to the Borrowers and Lender) without the
     obligation to pay any amendment fee (other than attorneys' fees and
     expenses incurred by Lender in preparing any required amendment documents)
     or Prepayment Fee by paying down the Loans with the proceeds of an initial
     public offering or a private placement of equity securities or subordinated
     debt.

     by delivering to Lender an irrevocable written notice in the form of
                                                                         
     Exhibit "B", appropriately completed (a "Notice of Borrowing/Conversion"),
     -----------                                                               
     which specifies, among other things:

                     (i)   The principal amount of the requested Loan Borrowing;

                     (ii)  Whether the requested Loan(s) are to consist of Prime

          excess thereof;

                     (iii) If the requested Loan(s) are to be Euro-Rate Loan(s),

                     (iv)  The date of the requested Loan, which shall be a

<PAGE>
 
     specified in Section 13.10; provided, however, that the Borrowers shall 
                  ------------- 
     promptly deliver to Lender the original of any Notice of
     Borrowing/Conversion initially delivered by telecopy. Notwithstanding the
     above, the Borrowers shall not have outstanding more than three (3) Euro-
     Rate Loans at any one time during the Initial Term or any Renewal Term of
     this Agreement.

               (c) Interest Rates.  The Borrowers shall pay interest on the
                   --------------                                          
     outstanding principal balance of each Loan from the date of such Loan until
     such Loan is repaid, at one of the following rates per annum:

                    (i)   During such periods as such Loan is a Prime Rate Loan,
          at a rate per annum equal to the Prime Rate plus one-half percent
                                                      ----

          three and one-quarter percent (3.25%).

          All outstanding Loans shall bear interest at one, and only one, of the
          above rates.  All computations of interest on Loans shall be based on
          a year of 360 days for actual days elapsed.

               (d) Conversion of Interest Rate on Loans.  The Borrowers may
                   ------------------------------------                    
     convert outstanding Prime Rate Loans into Euro-Rate Loans and outstanding
     Euro-Rate Loans into Prime Rate Loans; provided, however, that any
     conversion of Euro-Rate Loans into Prime Rate Loans shall be made on, and
     only on, the last day of an Interest Period for such Euro-Rate Loans.  The
     Borrowers shall request such a conversion by delivering to Lender an
     appropriately completed Notice of Borrowing/Conversion, which specifies,
     among other things:

                    (i)   The Prime Rate Portion or the Euro-Rate Portion which 
          is to be converted;

                    (ii)  The Type of Loans into which such Loans or Portion are
          to be converted;

                    (iii) If Prime Rate Loans are to be converted into Euro-Rate
          Loans, the Interest Period selected by the Borrowers for such Loans in

                    (iv)  The date of the requested conversion, which shall be a
          Business Day.

     three (3) Business Days before the date of the requested conversion in the
     case of a conversion into Euro-Rate Loans, and at least one (1) Business
     Day before the date of the requested conversion in the case of a conversion
     into Prime Rate Loans.  Each Request for Loan/Conversion shall be delivered
     to Lender at the office or to the 
<PAGE>
 
     telecopy number specified in Section 13.10; provided, however, that the 
                                  -------------            
     provided, however, that the Borrowers shall Borrowers shall promptly
     deliver to Lender the original of any Notice of Loan/Conversion initially
     delivered by telecopy.

               (e) Euro-Rate Interest Periods.  The initial and each subsequent
                   --------------------------                                  
     Interest Period selected by the Borrowers for a Euro-Rate Loan shall be
     thirty (30), sixty (60) or ninety (90) days; provided, however, that (A)
     any Interest Period which would otherwise end on a day which is not a
     Business Day shall be extended to the next succeeding Business Day, unless
     such next Business Day falls in another calendar month, in which case such
     Interest Period shall end on the immediately preceding Business Day; (B)
     any interest Period for a Euro-Rate Loan which begins on the last Business
     Day of a calendar month (or on a day for which there is no numerically
     corresponding day in the calendar month at the end of such Interest Period)
     shall end on the last Business Day of a calendar month; (C) no such
     Interest Period shall end after the Initial Term or any Renewal Term; and
     (D) no more than three (3) Loans bearing interest at the Euro-Rate may be
     originated or converted in any one month.  If the Borrowers fail to notify
     Lender of the next Interest Period for Euro-Rate Loans in accordance with
     this Section 2.1(e), such Loans shall automatically convert to Prime Rate
          --------------                                                      
     Loans on the last day of the current Interest Period therefor.

     2.2  Advances to Constitute One Loan; Loan Purpose.  All loans and advances
          ---------------------------------------------                         
by Lender to Borrower under this Agreement and the Ancillary Agreements shall
constitute one loan and all Liabilities of Borrower to Lender under this
Agreement and the Ancillary Agreements shall constitute one general obligation
secured by the Collateral.

     2.3  Interest Rate.  In no contingency or event whatsoever shall the rate
          -------------                                                       
or amount of interest paid by the Borrowers under this Agreement or any of the
Ancillary Agreements exceed the maximum rate or amount permissible under any law
which a court of competent jurisdiction shall, in a final determination, deem
applicable hereto.  In the event that such a court determines that Lender has
received interest hereunder or under any Ancillary Agreement in excess of the
maximum amount permitted by such law, (i) Lender shall apply such excess to any
unpaid principal owed by the Borrowers to Lender or, if the amount of such
excess exceeds the unpaid balance of such principal, Lender shall promptly
refund such excess interest to the Borrowers and (ii) the provisions hereof
shall be deemed amended to provide for such permissible rate.  All sums paid, or
agreed to be paid, by the Borrowers which are, or hereafter may be construed to
be, compensation for the use, forbearance or detention of money shall, to the
extent permitted by applicable law, be amortized, prorated, spread and allocated
throughout the full term of all such indebtedness until the indebtedness is paid
in full.

     2.4  Change of Circumstances.
          ----------------------- 

               (a) Inability to Determine Rates.  If, on or before the first day
                   ----------------------------                                 
     of any Interest Period of any Loan or Portion, (i) the Euro-Rate for such
     Interest Period cannot be adequately and reasonably determined due to the
     unavailability of funds in, or other circumstances affecting, the London
     interbank market or (ii) the Euro-Rates of interest for such Loans or
     Portions do not adequately and fairly reflect the cost to Lender of making
     or maintaining such Loans or Portions, Lender shall 
<PAGE>
 
     immediately give notice of such condition to Borrower. After the giving
     of any such notice and until Lender shall otherwise notify the Borrowers
     that the circumstances giving rise to such condition no longer exist, the
     Borrowers' right to request the making of or conversion to, and Lender's
     obligations to make or convert to Euro-Rate or Euro-Rate Portions of the
     Type affected by such condition shall be suspended. Any Euro-Rate Loans
     or Euro-Rate Portions of the Type affected by such condition outstanding
     at the commencement of any such suspension shall be converted at the end
     of the then current Interest Period for such Loans or Portions into
     another Type of Loan or Portion not affected by such suspension unless
     such suspension has then ended.

               (b) Illegality.  If, after the date of this Agreement the
                   ----------                                           
     adoption of any Governmental Rule, any change in any Governmental Rule or
     the application of requirements thereof (whether such change occurs in
     accordance with the terms of such Governmental Rule as enacted, as a result
     of amendment or otherwise), any change in the interpretation or
     administration of any Governmental Rule by any Governmental Authority, or
     compliance by Lender with any request or directive (whether of not having
     the force of law) of any Governmental Authority (a "Change of Law") shall
     make it unlawful or impossible for Lender to make or maintain any Euro-Rate
     Loan or Euro-Rate Portion, Lender shall immediately notify the Borrowers of
     such Change of Law.  Upon receipt of such notice, (i) the Borrowers' right
     to request the making of or conversion to, and Lender's obligations to make
     or convert to, any Loans or Portions of the Type affected by such Change of
     Law shall be terminated, and (ii) the Borrowers shall, at the request of
     Lender, either (A) pursuant to Section 2.1(d), as the case may be, convert
                                    --------------                             
     any such then outstanding Loans or Portions into another Type of Loans or
     Portions not affected by such Change of Law at the end of the current
     Interest Period for such Loans or Portions, or (B) immediately repay or
     convert any such Loans or Portions if Lender shall notify the Borrowers
     that the Lender may not lawfully continue to fund and maintain such Loans
     or Portions.  Any conversion or prepayment of Loans or Portions made
     pursuant to the preceding sentence prior to the last day of an Interest
     Period for such Loans or Portions shall be deemed a prepayment thereof for
     purposes of this Agreement.

               (c) Increased Costs.  If any Change of Law announced after the
                   ---------------                                           
     date of this Agreement:

                   (i)   Shall subject Lender to any tax, duty or other charge
          with respect to any Euro-Rate Loan or Euro-Rate Portion, or shall
          change the basis of taxation of payments by the Borrowers to Lender on
          such a Loan or Portion or in respect to such a Loan or Portion under
          this Agreement (except for changes in the rate of taxation on the
          overall net income of Lender); or

                   (ii)  Shall impose, modify or hold applicable any reserve,
          special deposit or similar requirement against assets held by,
          deposits or other liabilities in or for the account of, advances or
          loans by, or any other acquisition of funds by Lender for any Euro-
          Rate Loan or Euro-Rate Portion; or

                   (iii) Shall impose on Lender any other condition related to
          any Euro-Rate Loan or Euro-Rate Portion;
<PAGE>
 
     And the effect of any of the foregoing is to increase the cost to Lender of
     making, renewing, or maintaining any such Euro-Rate Loan or Euro-Rate
     Portion or to reduce any amount receivable by Lender hereunder; then the
     Borrowers shall from time to time, upon demand by Lender, pay to Lender
     additional amounts sufficient to reimburse Lender for such increased costs
     or to compensate Lender for such reduced amounts showing the calculation
     thereof in reasonable detail.  A certificate as to the amount of such
     increased costs or reduced amounts, submitted by Lender to the Borrowers
     shall, in the absence of manifest error, be conclusive and binding on the
     Borrowers for all purposes; provided, however, that the increased costs or
     reduced amounts shall not relate to any period more than 180 days prior to
     the date of such certificate.

               (d) Capital Requirements.  If, after the date of this Agreement,
                   --------------------                                        
     Lender determines that (i) any Change of Law announced after the date of
     this Agreement affects the amount of capital required or expected to be
     maintained by Lender or any Person controlling Lender (a "Capital Adequacy
     Requirement") and (ii) the amount of capital maintained by Lender or such
     Person which is attributable to or based upon the Loans or this Agreement
     must be increased as a result of such Capital Adequacy Requirement (taking
     into account Lender's or such Person's policies with respect to capital
     adequacy), the Borrowers shall pay to Lender or such Person, upon demand of
     Lender, such amounts as Lender or such Person shall determine are necessary
     to compensate Lender or such Person for the increased costs to Lender or
     such Person of such increased capital.  A certificate of Lender setting
     forth in reasonable detail the computation of any such increased costs,
     delivered by Lender to the Borrowers shall, in the absence of manifest
     error, be conclusive and binding on the Borrowers for all purposes;
     provided, however, that the increased costs or reduced amounts shall not
     relate to any period more than 180 days prior to the date of such
     certificate.

     2.5  Funding Loss Indemnification.  If the Borrowers shall (a) repay or
          ----------------------------                                      
prepay any Euro-Rate Loan or Euro-Rate Portion on any day other than the last
day of an Interest Period therefor (whether an optional prepayment, a mandatory
prepayment, a payment upon acceleration or otherwise) or (b) fail to borrow any
Euro-Rate Loan or Euro-Rate Portion for which a Notice of Borrowing has been
delivered to Lender (whether as a result of the failure to satisfy any
applicable conditions or otherwise), the Borrowers shall, upon demand by Lender,
reimburse Lender and hold Lender harmless for all costs and losses incurred by
Lender as a result of such repayment, prepayment or failure.  The Borrowers
understand that such costs and losses may include, without limitation, losses
incurred by Lender as a result of funding and other contracts entered into by
Lender to fund a Euro-Rate Loan or Euro-Rate Portion.  If Lender shall demand
payment under this Section 2.5, Lender shall deliver to the Borrowers a
                   -----------                                         
certificate setting forth the amount of costs and losses for which demand is
made, showing the calculation thereof in reasonable detail.  Such a certificate
so delivered to the Borrowers shall, in the absence of manifest error, be
conclusive and binding on the Borrowers as to the amount of such loss for all
purposes.

     2.6  Term of Agreement; Prepayment; Liquidated Damages.  This Agreement
          -------------------------------------------------
shall be in effect until two (2) years from the date hereof (the "Initial
Term") and shall be automatically renewed thereafter for successive periods of
one year (each a "Renewal Term") unless terminated as provided below. Either
party shall have the right to terminate 
<PAGE>
 
this Agreement at the end of the Initial Term or at the end of any Renewal
Term by giving the other party at least ninety (90) days' prior written notice
of such termination. In the event the Borrowers give notice of termination and
the Total Facility is not paid in full at the end of the Initial Term or
Renewal Term, as applicable, upon the request of the Borrowers, but in
Lender's sole discretion, Lender can continue to make advances and renew this
Agreement for an additional year, upon such terms and conditions as Lender may
require. In the event Lender does not agree to continue to make advances and
renew the term for an additional year, all Liabilities shall be immediately
due and payable. This Agreement may also be terminated by Lender upon the
occurrence of a Default. Upon the effective date of any termination, all of
the Liabilities shall become immediately due and payable without presentment,
notice or demand. Notwithstanding any termination, until all of the
Liabilities shall have been fully and finally paid and satisfied, Lender shall
be entitled to retain its security interest in the Collateral, the Borrowers
shall continue to remit collections of Accounts and proceeds of Collateral as
provided in this Agreement, and Lender shall retain all of its rights and
remedies under this Agreement. During the Initial Term or any Renewal Term,
the Borrowers may, at their option, upon not less than thirty (30) days
written notice to Lender specifying the date of prepayment, terminate this
Agreement on the first day of any month prior to the end of the Initial Term
or any Renewal Term and prepay all of the Liabilities hereunder. In such
event, the Borrowers shall pay to Lender, for loss of the bargain and not as a
penalty, as liquidated damages and as compensation for the costs of Lender
being prepared to make funds available to the Borrowers under this Agreement,
an amount (the "Prepayment Fee") equal to the following applicable percentage
of the Total Facility:


        Prepayment Date                        Applicable Prepayment Fee      
        ---------------                        -------------------------      
                                                                              
        After the Closing Date                 Two percent (2.0%) of the      
        and before the first                   Total Facility                 
        anniversary of this                                                   
        Agreement                              
                                               
        From and after the first               One and one-half percent        
        anniversary of this                    (1.50%) of the Total Facility   
        Agreement and before the                                               
        second anniversary of                  
        this Agreement                         
                                               
        During the first Renewal               One percent (1.00%) of           
        Term of this Agreement                 the Total Facility               
                                                                                
        At any time after the first            Zero percent (0.00%) of          
        Renewal Term of this Agreement         the Total Facility        

    
     The Borrowers shall also be responsible to pay, in every event, Euro-
Rate breakage penalties pursuant to Section 2.5, and if any fixed rate Loan is 
                                    ----------- 
outstanding, the Borrowers agree to pay an additional prepayment charge equal
to the actual loss, if any, that may be sustained by Lender through
redeployment of the funds loaned to the Borrowers at the then prevailing
interest rates.

     2.7  Credit Availability Charge.  To compensate Lender for the costs of
          --------------------------                                        
being prepared to make funds available to the Borrowers, the Borrowers agree
that if, during any such month, the daily average outstanding borrowings under
the Total Facility is less than Seven Million Five Hundred Thousand Dollars
($7,500,000), then the Borrowers shall pay to Lender at the end of each such
month a Credit Availability Charge, in addition to accrued 
<PAGE>
 
interest on the outstanding Liabilities, equal to such shortfall times the
applicable Prime Rate based interest rate for the Loans. The Credit
Availability Charge is in addition to any other applicable fees and charges
and shall be payable for the entire period covered by the Initial Term and
each Renewal Term, unless this Agreement is terminated by the Borrowers
pursuant to Section 2.6 above and the Borrowers have paid the applicable 
            -----------              
Prepayment Fee and Euro-Rate breakage penalties. The Credit Availability
Charge shall be payable monthly during the Initial Term and during each
Renewal Term or immediately upon termination if this Agreement is terminated
prior to the end of the Initial Term or a Renewal Term.

     2.8  Audit Fee.  The Borrowers shall pay to Lender its reasonable costs and
          ---------                                                             
expenses incurred during the course of field examinations and audits, which
Lender will conduct on a quarterly basis prior to the existence of a Default and
as frequently as Lender may require following the occurrence and during the
continuance of a Default, including a per diem charge for examiners in the field
and office at Lender's then prevailing rate (currently $750 per person per day),
not to exceed aggregate examiners' charges of $3,000 plus reasonable costs and
expenses for any one field examination or audit occurring prior to a Default.

     2.9  Loan Fee.  The Borrowers shall pay Lender in cash, on the Closing
          --------                                                         
Date, a Loan Fee equal to one percent (1.00%) of the Total Facility, with such
Loan Fee being credited on the Closing Date with the $50,000 portion of the

Loans made by Lender to the Borrowers pursuant to this Agreement, (ii) all
payments made by the Borrowers on all such Loans and (iii) all other appropriate
debits and credits as provided in this Agreement, including, without limitation,

from time to time.  Unless otherwise agreed to in writing, all payments which
the Borrowers are required to make to Lender under this Agreement or under any
of the Ancillary Agreements shall be made by appropriate debits to the Loan
Account.  Lender may, in its discretion, elect to bill the Borrowers for the
amount of any such payment in which case such amount shall be immediately due
and payable with interest thereon at the rate set forth in Section 2.3.
                                                           ----------- 

     4.2  Payment Terms.  Unless otherwise expressly provided in writing, the
          -------------                                                      
Liabilities will be repayable as follows: (i) interest shall be payable on the
first day of each month (for the immediately preceding month) out of the first
collections received with respect to any proceeds of Collateral, (ii) fees,
costs, expenses and similar charges shall be payable as and when provided for in
this Agreement or the Ancillary Agreements and (iii) the principal balance of
the Liabilities shall be payable from collections received with respect to any
proceeds of Collateral as such proceeds are received; provided, however, that if

percentage or dollar limitations set forth in Section 2.1(a), or the outstanding
                                              --------------

excess.  All of the Liabilities shall be payable at the address set forth in

- -------------                                                                
sell, lease or otherwise dispose of any Collateral other than as expressly set
forth in Sections 6.4, 7.1 and 8.3.
         ------------  ---     --- 

     4.3  Collection of Accounts and Payments.  The Borrowers shall establish
          -----------------------------------                                
such blocked accounts or lockbox accounts as Lender may require, into which the
Borrowers will immediately deposit all remittances and proceeds of the
Collateral in the identical form in which such payment was made, whether by cash
or check.  The banks with which such accounts are maintained (collectively, the
"Depository Banks") shall acknowledge and agree, in a manner satisfactory to
Lender, that all payments made to such  accounts are the sole and exclusive
property of Lender, that the Depository Banks have no right of setoff against
the funds in such accounts and that the Depository Banks will wire, or otherwise
transfer immediately available funds in a manner satisfactory to Lender, funds
deposited in such accounts to Lender on a daily basis as soon as such funds are
collected.  The Borrowers hereby agree that all payments made to such  accounts
or otherwise received by Lender, 
<PAGE>
 
whether on the Accounts or as proceeds of other Collateral or otherwise, will
be the sole and exclusive property of Lender and will be applied on account of
the Liabilities. After allowing one (1) business day for collection after such
funds are received by Lender, Lender will credit (conditional upon final
collection) all payments received through such accounts to the Loan Account.
The Borrowers and any Affiliates, shareholders, directors, officers,
employees, agents of the Borrowers and all Persons acting for or in concert
with the Borrowers who receive any monies, checks, notes, drafts or any other
payments relating to or proceeds of Accounts or other Collateral which come
into their possession or under their control shall, acting as trustee for
Lender, hold such property as the sole and exclusive property of Lender and
immediately upon receipt thereof, shall remit the same or cause the same to be
remitted, in kind, to Lender. The Borrowers agree to pay to Lender any and all
fees, costs and expenses (if any) which Lender incurs in connection with
opening and maintaining the accounts and depositing for collection by Lender
any check or item of payment received or delivered to any Depository Bank or
Lender on account of the Liabilities and the Borrowers further agree to
reimburse Lender for any claims asserted by any Depository Bank in connection
with any account or any returned or uncollected checks received by any
Depository Bank for deposit in the accounts.

     4.4  Application of Payments and Collections.  The Borrowers irrevocably
          ---------------------------------------                            
waive the right to direct the application of payments and collections received
by Lender from or on behalf of the Borrowers, and the Borrowers agree that
Lender shall have the continuing exclusive right to apply and reapply any and
all such payments and collections against the Liabilities in such manner as
Lender may deem appropriate, notwithstanding any entry by Lender upon any of its
books and records.  To the extent that the Borrowers make a payment or payments
to Lender or Lender receives any payment or proceeds of the Collateral for the
Borrowers' benefit, which payment(s) or proceeds or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, receiver or any other party under any
bankruptcy act, state or federal law, common law or equitable cause, then, to
the extent such payment or proceeds received are so set aside, invalidated,
required to be repaid or the like, the Liabilities or part thereof intended to
be satisfied shall be revived and shall continue in full force and effect, as if
such payments or proceeds had not been received by Lender.

     4.5  Statements.  All Loans and all other debits and credits provided for
          ----------                                                          
in this Agreement, shall be evidenced by entries made by Lender in its internal
data control systems showing the date, amount and reason for each such debit or
credit.  Until such time as Lender shall have rendered to the Borrowers written
statements of account as provided herein, the balance in the Loan Account, as
set forth on Lender's most recent statement, reasonably maintained, shall be
presumptive evidence of the amounts due and owing to Lender by the Borrowers.
Not more than ten (10) days after the final day of each calendar month, Lender
shall render to the Borrowers a statement setting forth the balance of the Loan
Account, and such other information in substantially the form attached hereto as
Exhibit "I".  Each such statement shall be subject to subsequent adjustment by
Lender and Lender's right to reapply payments in accordance with Section 4.4,
                                                                 ----------- 
but shall, absent manifest errors or omissions, be presumed correct and binding
upon the Borrowers and shall constitute an account stated unless, within thirty
(30) days after receipt of any statement from Lender, the Borrowers shall
deliver to Lender written objection thereto specifying the error or errors, if
any, contained in such statement.

          ----------------------------------                                   
and accurate daily records on a first-in, first-out basis, itemizing and
describing the kind, type, quality and quantity of Inventory, the Borrowers'
cost therefor and selling price thereof, and the daily withdrawals therefrom and
additions thereto and Inventory then on consignment, if any, provided that
Lender's prior written consent to such consignment must be obtained, and shall
furnish to Lender,  monthly by the fifteenth (15th) day of the following month,
a current updated Inventory Report, based on a first in-first out cost
assumption. A physical count of the Inventory shall be conducted no less often

including, without limitation invoices relating to Borrowers' purchase of goods
listed in said Report, as Lender shall, in its sole discretion, request.

Borrower, such Borrower shall promptly determine the reason for such return and,
if Borrower accepts such return, issue a credit memorandum (with a copy to be
immediately sent to Lender) in the appropriate

amount to such Account Debtor; provided, however, that no Borrower shall,
without the prior consent of Lender, accept on any single day, returned
Inventory the sale price of which was in excess of Twenty-Five Thousand
Dollars ($25,000) in the aggregate. After the occurrence of a Default, the
Borrowers shall hold all returned Inventory in trust for Lender, shall
segregate all returned Inventory from all other property of the Borrower or in

necessary replacements thereof so that the value, utility and operating
efficiency thereof shall at all times be maintained and preserved and shall
promptly inform Lender of any material additions to or deletions from the
Equipment.  The Borrowers shall not permit any such Equipment to become affixed
to real estate in such manner that such Equipment will become a fixture or an
accession to other personal property.

     8.2  Evidence of Ownership of Equipment.  The Borrowers shall, upon
          ----------------------------------

lease, grant a security interest in (other than a Permitted Lien) or otherwise
dispose of or encumber the Equipment or any part thereof to any Person other
than Lender; provided, however, that in any fiscal year of the Borrowers, the
Borrowers may sell or otherwise dispose of Equipment with an aggregate net book
value not to exceed Fifty Thousand Dollars ($50,000).  In the event any
Equipment is sold, transferred or otherwise disposed of as permitted in this
Section, the Borrowers shall promptly notify Lender of such fact and deliver all
of the cash proceeds of such sale, transfer or disposition to Lender, which
proceeds shall be applied to the repayment of the Liabilities; provided,
however, that with Lender's prior consent the Borrowers may use the proceeds of
such sale, transfer or disposition to finance the purchase of replacement
Equipment in which Lender has a first, perfected security interest documented to
the satisfaction of Lender.  The Borrowers shall deliver to Lender written
evidence of the use of the proceeds for such purchase.  All replacement
Equipment purchased by the Borrowers shall be free and clear of all liens,
claims, security interests and other encumbrances, except for the security
interest granted to Lender and Permitted Liens.

the Borrowers may dispute any Charges without prior payment thereof, even if
such non-payment may cause a lien to attach to a Borrower's assets, provided
that the Borrowers shall give Lender prompt notice of such dispute and shall be
diligently contesting the same in good faith and by an appropriate proceeding
and there is no danger of a loss or forfeiture of any of the Collateral or of
Lender's priority position with respect to such Collateral and provided further
that, if the same are potentially or actually in excess of Twenty-Five Thousand
Dollars ($25,000) in the aggregate at any time hereafter, the Borrowers shall
give Lender such additional collateral and assurances as Lender, in its sole
discretion, deems necessary under the circumstances, immediately upon demand by
Lender.

     10.4 Payment of Charges.  Subject to the provisions of Section 10.3, the
          ------------------                                ------------     
Borrowers shall pay all of the Charges promptly when due .  In the event the
Borrowers, at any time or times hereafter, shall fail to pay the Charges or to
promptly obtain the satisfaction of such Charges, the Borrowers shall promptly
so notify Lender thereof and Lender may, without waiving or releasing any
obligation or liability of the Borrowers hereunder or any Default, in its sole
discretion, at any time or times thereafter, make such payment or any part
thereof, (but shall not be obligated so to do) or obtain such satisfaction and
take any other action with respect thereto which Lender deems advisable.  All
sums so paid by Lender and any expenses, including reasonable attorneys' fees,
court costs, expenses and other charges relating thereto, shall be payable by
the Borrower to Lender upon demand and shall be additional Liabilities.

     10.5 Insurance; Payment of Premiums.  At their sole cost and expense, the
          ------------------------------                                      
Borrowers shall (i) keep and maintain the Collateral insured for the greater of
original cost or replacement value of the Collateral against loss or damage by
fire, theft, explosion, sprinklers and all other hazards and risks in amounts
customary for companies of similar size engaged in the same or similar
businesses; (ii) maintain product liability insurance in an amount customary for
the business conducted by the Borrowers and acceptable to Lender; and (iii)
general public liability insurance in an amount satisfactory to Lender but in no
event 
<PAGE>
 
less than Two Million Dollars ($2,000,000) per occurrence, for bodily
injury and property damage.  All policies of insurance on the Collateral or
otherwise required hereunder shall be in form and amount satisfactory to Lender
and with insurers reasonably recognized as adequate by Lender.  The Borrowers
shall deliver to Lender a copy of each policy of insurance and, if requested,
evidence of payment of all premiums therefor and shall deliver renewals of all
such policies to Lender at least thirty (30) days prior to their expiration
dates.  Such policies of insurance shall contain an endorsement, in form and
substance acceptable to Lender, showing all losses payable to Lender. Such
endorsement shall provide that the insurance companies will give Lender at least
thirty (30) days' prior notice before any such policy shall be altered or
canceled and that no act or default of any Borrower or any other person shall
affect the right of Lender to recover under such policy in case of loss or
damage.  The Borrowers hereby direct all insurers under such policies to pay all
proceeds payable thereunder directly to Lender.  After the occurrence and during
the continuance of a Default, each of the Borrowers irrevocably makes,
constitutes and appoints Lender (and all officers, employees or agents
designated by Lender) as such Borrower's true and lawful attorney and agent-in-
fact for the purpose of making, settling and adjusting claims under such
policies (provided that Lender shall consult with such Borrower prior to
finally making, settling or adjusting claims under such policies), endorsing
the name of such Borrower in writing or by stamp on any check, draft,
instrument or other item of payment for the proceeds of such policies and for
making all determinations and decisions with respect to such policies. If the
Borrowers shall fail to obtain or maintain any of the policies required by
this Section 10.5 or to pay any premium relating thereto, then Lender, without 
     ------------                                             
waiving or releasing any obligation or default by the Borrowers hereunder, may
(but shall be under no obligation to do so) obtain and maintain such policies
of insurance and pay such premiums and take any other action with respect
thereto which Lender deems advisable. All sums so disbursed by Lender,
including reasonable attorneys' fees, court costs, expenses and other charges
relating thereto, shall be payable by the Borrowers to Lender upon demand and
shall be additional Liabilities.

     10.6 Survival of Obligations Upon Termination of Agreement.  Except as
          -----------------------------------------------------            
otherwise expressly provided for in this Agreement and in the Ancillary
Agreements, no termination or cancellation (regardless of cause or procedure) of
this Agreement or the Ancillary Agreements shall in any way affect or impair the
powers, obligations, duties, rights, and liabilities of the Borrowers or Lender
in any way or respect relating to any transaction or event occurring prior to
such termination or cancellation, the Collateral, or any of the undertakings,
agreements, covenants, warranties and representations of the Borrowers or Lender
contained in this Agreement or the Ancillary Agreements.  All such undertakings,
agreements, covenants, warranties and representations shall survive such
termination or cancellation.

     10.7 Environmental Indemnity.  Each of the Borrowers hereby indemnifies
          -----------------------                                           
Lender, its successors and assignees, and agrees to hold Lender harmless from
and against any and all losses, liabilities, damages, injuries, costs, expenses
and claims of any and every kind whatsoever (including, without limitation,
court costs and attorneys' fees) which at any time or from time to time may be
paid, incurred or suffered by, or asserted against, Lender for, with respect to,
or as a direct or indirect result of the violation by such Borrower, any other
obligor or any of such Borrower's Subsidiaries, of any laws, including but not
limited to, the Environmental Laws or any laws or regulations relating to
Hazardous Materials, treatment, storage, disposal, generation and
transportation, air, water and noise pollution, soil or ground 
<PAGE>
 
or water contamination, the handling, storage or release into the environment
of Hazardous Materials; or with respect to, or as a direct or indirect result
of the presence on or under, or the escape, seepage, leakage, spillage,
discharge, emission or release from, properties utilized by such Borrower, any
other obligor or any of such Borrower's Subsidiaries in the conduct of their
respective business into or upon any land, the atmosphere, or any watercourse,
body of water or wetland, of any Hazardous Materials (including, without
limitation, any losses, liabilities, damages, injuries, costs, expenses or
claims asserted or arising under the Environmental Laws) provided that such
Borrower shall not be liable to any indemnified party with respect to any
matter arising from such indemnified party's gross negligence or wilful
misconduct; and the provisions of and undertakings and indemnification set out
in this Section shall survive the satisfaction and payment of the Liabilities
and the termination of this Agreement.

     10.8 Change of Control.  It is covenanted and agreed by the Borrowers that
          -----------------                                                    
no person or group which is not a shareholder in or beneficial owner of any of
the Borrowers as of the Closing Date, shall directly or indirectly acquire the
legal or beneficial ownership of more than five percent (5%) of the Borrowers;
provided, however, that if such group is Levine & Leichtman Capital Partners,
Weston Presidio Capital or other comparable investment firm reasonably
acceptable to Lender, the above five percent (5%) limitation shall be increased
to twenty-five percent (25%).  In addition, Donald J. Esters and his family
partnership or trust collectively shall be required to maintain legal or
beneficial ownership, either directly or by ownership of shares in the
Borrowers' parent company in a sufficient amount to have the power to direct or
cause the direction of management, operation or policies of the Borrowers.  In
no event, however, shall any other group or person (other than Donald J. Esters
and his family partnership or trust) obtain the power to elect, appoint or cause
the election or appointment of, a majority of the members of the Board of
Directors of any Borrower, through beneficial ownership of capital stock of such
Borrower or otherwise.

     10.9 Revisions or Updates.  Should any of the information or disclosures
          --------------------                                               
provided on any of the Schedules or Exhibits originally attached hereto become
outdated or incorrect in any material respect, the Borrowers promptly shall
provide to Lender such revisions or updates as may be necessary or appropriate
to update or correct such Schedule(s) or Exhibit(s); provided that no such
revisions or updates shall be deemed to have amended, modified or superseded
such Schedule or Exhibit as originally attached hereto, or to have cured any
breach of warranty or representation resulting from the inaccuracy or
incompleteness of any such Schedule or Exhibit unless and until Lender, in its
sole and absolute discretion, shall have accepted in writing such revisions or
updates.

               (m) Any individual who is a Guarantor shall die or become

          -------------------------------                                     
Default, all of the Liabilities may, at the option of Lender and without demand,
notice, or legal process of any kind, be declared, and immediately shall become,
due and payable.

     12.3 Advances During Cure Period.  Upon the occurrence of a Default which
          ---------------------------                                         
is subject to any cure period, Lender may, in its sole discretion, cease making

such Default rate to begin upon the occurrence of the Default and to be adjusted
upon any interest rate change as provided herein.

     12.5 Remedies.  Upon and after the occurrence of a Default, Lender shall

have all of 
<PAGE>
 
the following rights and remedies:

               (a) All of the rights and remedies of a secured party under the
     California Commercial Code or any other applicable law, all of which rights
     and remedies shall be cumulative, and not exclusive, to the extent
     permitted by law and in addition to any other rights and remedies contained
     in this Agreement and in any of the Ancillary Agreements;

               (b) The right to (i) peacefully enter upon the premises of any
     Borrower or any other place or places where the Collateral is located,
     without any obligation to pay rent to any Borrower or any other Person,
     through self-help and without judicial process or first obtaining a final
     judgment or giving any Borrower notice and opportunity for a hearing on the
     validity of Lender's claim, and remove the Collateral from such premises
     and places to the premises of Lender or any agent of Lender, for such time
     as Lender may require to collect or liquidate the Collateral, and/or (ii)
     require the Borrowers to assemble and deliver the Collateral to Lender at a
     place to be designated by Lender;

               (c) The right to (i) open any Borrower's mail and collect any and
     all amounts due from Account Debtors or direct that any Borrower's mail be
     diverted to a post office box or other location as determined by Lender,
     (ii) notify Account Debtors that the Accounts have been assigned to Lender
     and that Lender has a security interest therein and (iii) direct such
     Account Debtors to make all payments due from them upon the Accounts,
     including the Special Collateral, directly to Lender or to a lock box
     designated by Lender.  Lender shall promptly furnish the Borrowers with a
     copy of any such notice sent and the Borrowers hereby agree that any such
     notice in Lender's sole discretion, may be sent on Lender's stationery, in
     which event, the Borrowers shall, upon demand, co-sign such notice with
     Lender;

               (d) The right to sell, lease or to otherwise dispose of all or
     any Collateral in its then condition, or after any further manufacturing or
     processing thereof, at public or private sale or sales, in lots or in bulk,
     for cash or on credit, all as Lender, in its sole discretion, may deem
     advisable.  At any such sale or sales of the Collateral, the Collateral
     need not be in view of those present and attending the sale, nor at the
     same location at which the sale is being conducted. Lender shall have the
     right to conduct such sales on the Borrowers' premises or elsewhere and
     shall have the right to use the Borrowers' premises without charge for such
     sales for such time or times as Lender may see fit.  Lender is hereby
     granted a license or other right to use, without charge, the Borrowers'
     labels, patents, copyrights, rights of use of any name, trade secrets,
     trade names, trademarks and advertising matter, or any property of a
     similar nature, as it pertains to the Collateral, in advertising for sale
     and selling any Collateral and the Borrowers' rights under all licenses and
     all franchise agreements shall inure to Lender's benefit but Lender shall
     have no obligations thereunder.  Lender may purchase all or any part of the
     Collateral at public or, if permitted by law, private sale and, in lieu of
     actual payment of such purchase price, may setoff the amount of such price
     against the Liabilities.  The proceeds realized from the sale of any
     Collateral shall be applied first to the costs, expenses and attorneys'
     fees and expenses incurred by Lender for collection and for acquisition,
     completion, protection, removal, storage, sale and delivery of the
     Collateral; second 
<PAGE>
 
     to interest due upon any of the Liabilities; and third to the principal
     of the Liabilities. Lender shall account to the Borrowers for any
     surplus. If any deficiency shall arise, the Borrowers shall remain liable
     to Lender therefor.

     12.6 Notice.  The Borrowers agree that any notice required to be given by
          ------                                                              
Lender of a sale, lease, or other disposition of any of the Collateral or any
other intended action by Lender, which is personally delivered to the Borrowers
or which is deposited in the United States mail, postage prepaid and duly
addressed to the Borrowers at the address set forth in Section 13.10, at least
                                                       -------------          
five (5) days prior to any such public sale, lease or other disposition or other
action being taken, or the time after which any private sale of the Collateral
is to be held, shall constitute commercially reasonable and fair notice thereof
to the Borrowers.

          -------------------------------------------------------------         
any time or times, whether prior or subsequent to the date hereof and regardless
of the existence of a Default or an Event of Default, Lender incurs legal or
other costs and expenses or employs counsel, accountants, advisors, consultants
and/or other professionals for advice or other representation or services in
connection with:

               (a) The preparation, negotiation, execution and administration of
     this Agreement, all Ancillary Agreements, any amendment of or modification
     of this Agreement or the Ancillary Agreements or any sale or attempted sale
     of any interest herein to a Participant;

               (b) Any litigation, contest, dispute, suit, proceeding or action

to require strict performance by the Borrowers of any provision of this
Agreement or the Ancillary Agreements shall not constitute a waiver, or affect
or diminish any right of Lender thereafter to demand strict compliance and
performance herewith or therewith.  Any suspension or waiver by Lender of a
Default under this Agreement or the Ancillary Agreements shall not suspend,
waive or affect any other Default under this Agreement or the Ancillary
Agreements, whether the same is prior or subsequent thereto and whether of the
same or of  a different type.  None of the undertakings, agreements, warranties,
covenants and representations of the Borrowers contained in this Agreement or
the Ancillary Agreements and no Default under this Agreement or the Ancillary
Agreements shall be deemed to have been suspended or waived by Lender, unless
such suspension or waiver is by an instrument in writing signed by an officer of

the Ancillary Agreements shall be interpreted in such manner as to be effective
and valid under applicable law, but if any provision of this Agreement or the
Ancillary Agreements shall be prohibited by or invalid under applicable law,
such provision shall be ineffective to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the
remaining provisions of this Agreement or the Ancillary Agreements.

     13.6 Parties; Entire Agreement.  This Agreement and the Ancillary
          -------------------------

successors and assigns of the Borrowers and Lender.  The Borrowers' respective
successors and assigns shall include, without limitation, a trustee, receiver or
debtor-in-possession of or for any of the Borrowers.  Nothing contained in this
Section shall be deemed to modify Section 13.2.  This written Agreement, the

Ancillary Agreements and the other documents described or contemplated herein
represent the final agreement between the parties, embody the entire agreement
and understanding between the parties hereto and thereto, supersede all prior
agreements and understandings related to the subject matter hereof and thereof,
and may not be contradicted by evidence of prior, contemporaneous, or subsequent

          -----------------                                                 
incorporated in this Agreement by this reference.  Except as otherwise provided
in this Agreement and except as otherwise provided in the Ancillary Agreements
by specific reference to the applicable provision of this Agreement, if any
provision contained in this Agreement is in conflict with, or inconsistent with,
any provision in any Ancillary Agreement, the provision contained in this
Agreement shall govern and control.

     13.8 Waiver by Borrower.  Except as otherwise provided for in this
          ------------------                                           
Agreement, each Borrower waives (a) presentment, demand and protest, notice of
protest, notice of presentment, default, non-payment, maturity, release,
compromise, settlement, extension or 
<PAGE>
 
renewal of any or all commercial paper, accounts, contract rights, documents,
instruments, chattel paper and guaranties at any time held by Lender on which
such Borrower may in any way be liable and hereby ratifies and confirms
whatever Lender may do in this regard; (b) all rights to notice and a hearing
prior to Lender's taking possession or control of, or to Lender's replevy,
attachment or levy upon, the Collateral or any bond or security which might be
required by any court prior to allowing Lender to exercise any of Lender's
remedies; and (c) the benefit of all valuation, appraisement, extension and
exemption laws. Each Borrower acknowledges that it has been advised by its own
counsel with respect to this Agreement and the transactions evidenced by this
Agreement. Each Borrower further agrees that (y) Lender shall have no
obligation to take, and such Borrower shall have the sole responsibility for
taking, any and all steps to preserve rights against any and all Account
Debtors and against any and all prior parties to any note, chattel paper,
draft, trade acceptance, or other instrument for the payment of money covered
by the security interest whether or not in Lender's possession and (z) Lender
shall not be responsible to such Borrower for loss or damage resulting from
Lender's failure to enforce any Accounts or to collect any moneys due or to
become due thereunder or other proceeds constituting Collateral hereunder
unless such loss or damage results from Lender's gross negligence or willful
misconduct.

     13.9  Governing Law, Venue.  This Agreement has been delivered for
           --------------------

and construed in accordance with the internal laws (as opposed to the conflicts
of law provisions) of the State of California as the same may from time to time
be in effect, including without limitation the Uniform Commercial Code as

jurisdiction of any state or federal court located in Los Angeles County,
California over any action or proceeding to enforce or defend any matter arising
from or related to this Agreement; (b) waives personal service of any and all
process upon such Borrower, and consents that all such service of process be
made by messenger, certified mail or registered mail directed to such Borrower
at the address set forth in Section 13.10 and service so made shall be deemed to
                            -------------                                       
be completed upon the earlier of actual receipt or three (3) days after the same

the fullest extent such Borrower may effectively do so, the defense of an

officers, employees, agents or property, concerning any matter arising out of or

     performed, fulfilled or given to Lender pursuant to this Agreement or the
     Ancillary Agreements, Lender shall not be deemed to have warranted or
     represented the sufficiency, legality, effectiveness or legal effect of the
     same, or of any term, provision or condition thereof, and such acceptance
     or approval thereof shall not constitute a warranty or representation to
     anyone with respect thereto by Lender;

               (c) The relationship between each Borrower and Lender is, and
     shall at all times remain, solely that of a borrower and lender; Lender
     shall not under any circumstance be construed to be a partner or joint
     venturer of any Borrower; Lender shall not under any circumstance be deemed
     to be in a fiduciary relationship with any Borrower; Lender does not
     undertake or assume any responsibility or duty to any Borrower to select,
     review, inspect, supervise, pass judgment upon or inform such Borrower of
     any matter in connection with its property or the operations of such
     Borrower; each Borrower shall rely entirely upon its own judgment with
     respect to such matters; and any review, inspection, supervision, exercise
     of judgment or supply of information undertaken or assumed by Lender in
     connection with such matters is solely for the protection of Lender and
     neither such Borrower nor any other Person is entitled to rely thereon; and

               (d) Lender shall not be responsible or liable to any Person for
     any loss, damage, liability or claim of any kind relating to injury or
     death to such Persons or damage to property not caused by Lender and caused
     by the actions, inaction or negligence of any Borrower and each Borrower
     hereby indemnifies and holds Lender harmless from any such loss, damage,
     liability or claim.


     13.15 Time of the Essence.  Time is of the essence hereunder and under the
           -------------------                                                 
Ancillary Agreements.

     13.16 Indemnification.
           --------------- 

          If after receipt of any payment of all or any part of the
Indebtedness, Lender is for any 
<PAGE>
 
reason compelled to surrender such payment to any Person, because such payment
is determined to be void or voidable as a preference, impermissible setoff, or
a diversion of trust funds, or for any other reason, this Agreement shall
continue in full force and the Borrowers shall be liable to, and shall
indemnify and hold Lender harmless for, the amount of such payment
surrendered. The provisions of this Section shall be and remain effective
notwithstanding any contrary action which may have been taken by Lender in
reasonable reliance upon such payment, and any such contrary action so taken
shall be without prejudice to Lender's rights under this Agreement and shall
be deemed to have been conditioned upon such payment having become final and
irrevocable. The provisions of this Section shall survive the termination of
this Agreement.

          Each Borrower agrees to indemnify, save and hold harmless Lender and
its directors, officers, agents, attorneys and employees (collectively the
"Indemnitees") from and against:  (i) Any and all claims, demands, actions or
causes of action that are asserted against any Indemnitee by any Person if the
claim, demand, action or cause of action directly or indirectly relates to a
claim, demand, action or cause of action that such Person asserts or may assert
against such Borrower, or any Affiliate or any officer, director or shareholder
of such Borrower and such claim, demand, action or cause of action arises out of
or relates to this Agreement or the Ancillary Agreements, the use of proceeds of
any advance, or the relationship of such Borrower and Lender under this
Agreement; (ii) Any and all claims, demands, actions or causes of action if the
claim, demand, action or cause of action arises out of or relates to such
Borrower's compliance or noncompliance with the requirements of any
environmental law;  (iii) Any administrative or investigative proceeding by any
governmental agency arising out of or related to a claim, demand, action or
cause of action described in clauses (i) or (ii) above; and (iv) Any and all
liabilities, losses, costs or expenses (including reasonable attorneys' fees and
                                        ---------                               
disbursements and other professional services) that any Indemnitee suffers or
incurs as a result of the assertion of any foregoing claim, demand, action or
cause of action; provided that no Indemnitee shall be entitled to
                 --------                                        
indemnification for any loss caused by its own gross negligence or willful
misconduct.  Each Indemnitee is authorized to employ counsel of its own choosing
in enforcing its rights hereunder and in defending against any claim, demand,
action or cause of action covered by this Section; provided that each Indemnitee
                                                   --------                     
shall endeavor, in connection with any matter covered by this Section which also
involves other Indemnitees, to use reasonable efforts to avoid unnecessary
duplication of effort by counsel for all Indemnitees.  Whenever practicable,
upon obtaining actual knowledge of any event that would entitle Lender to be
indemnified under this Section, Lender shall endeavor to provide notice to the
Borrowers of such fact and Lender shall cooperate with Borrower to endeavor to
minimize the liabilities for which Lender is entitled to be indemnified.  Any
obligation or liability of Borrower to any Indemnitee under this Section shall
survive the expiration or termination of this Agreement and the repayment of all
Liabilities and the payment and performance of all other obligations under this
Agreement owed to Lender.

    13.17 Suretyship Waivers and Consents.  (a) The obligations of each Borrower
          -------------------------------                                       
are independent of the obligations of all of the other Borrowers.  Each Borrower
expressly waives any right to require Lender to proceed against any other
Borrower, to proceed against or exhaust any Collateral or any other security for
the Liabilities or to pursue any remedy Lender may have at any time.  Each
Borrower agrees that Lender may proceed against any one or more of the Borrowers
and/or the Collateral in such order and manner as Lender shall determine in its
sole and absolute discretion.  A separate action or actions may 
<PAGE>
 
be brought and prosecuted against any one or more of the Borrowers whether an
action is brought or prosecuted against any other Borrower or with respect to
any Collateral or whether any other Person shall be joined in any such action
or actions. Each Borrower expressly waives the benefit of any statute(s) of
limitations affecting its liability under this Agreement or the Ancillary
Documents or the enforcement of the Liabilities or any rights of Lender
created or granted under this Agreement or the Ancillary Documents. Lender's
rights hereunder and under the Ancillary Documents shall be reinstated and
revived, and the obligations and liability of each Borrower hereunder and
thereunder shall continue, with respect to any amount at any time paid on
account of the Liabilities which thereafter shall be required to be restored
or returned by Lender upon the bankruptcy, insolvency or reorganization of any
Borrower, or otherwise, all as though such amount had not been paid.

               (b) Each Borrower expressly waives any and all defenses now or
hereafter arising or asserted by reason of (i) any disability or other defense
of any other Borrower or with respect to the Liabilities; (ii) the cessation for
any cause whatsoever of the liability of any other Borrower and (iii) any act or
omission of Lender or others that directly or indirectly results in or aids the
discharge or release of any other Borrower or the Liabilities or any Collateral
or guaranty therefor by operation of law or otherwise. Each Borrower agrees that
any amounts received by Lender from whatever source on account of the
Liabilities may be applied by Lender toward the payment of such of the
Liabilities and in such order of application as Lender may from time to time
elect; and, notwithstanding any payments made by any Borrower, such Borrower
shall have no right of subrogation, reimbursement, exoneration, indemnity,
contribution or any other rights that would result in such Borrower being deemed
a creditor of any other Borrower under the federal Bankruptcy Code or any other
law or for any other purpose and such Borrower hereby irrevocably waives all
such rights, the right to assert any such rights and any right to enforce any
remedy which Lender now or may hereafter have against any Borrower and hereby
irrevocably waives any benefit of and any right to participate in, any security
now or hereafter held by Lender, whether any of the foregoing rights arise in
equity, at law or by contract.

               (c) Each Borrower represents and warrants to Lender that it has
established adequate means of obtaining from each of the other Borrowers, on a
continuing basis, financial and other information pertaining to the businesses,
operations and condition (financial and otherwise) of each of the other
Borrowers and its properties, and each Borrower now is and hereafter will be
completely familiar with the businesses, operations and condition (financial and
otherwise) or each of the other Borrowers and their properties. Each Borrower
hereby expressly waives and relinquishes any duty on the part of Lender (should
any such duty exist) to disclose to any Borrower any matter, fact or thing
related to the businesses, operations or condition (financial or otherwise) of
any Borrower or their properties, whether now known or hereafter known by
Lender.

               (d) Each Borrower represents and warrants that each of the
waivers set forth herein is made with each Borrower's full knowledge of its
significance and consequences, and that under the circumstances the waivers are
reasonable and not contrary to public policy or law. If any of such waivers is
determined to be contrary to any applicable law or public policy, such waiver
shall be effective only to the
<PAGE>
 
maximum extent permitted by law.

     13.18  WAIVER OF RIGHT TO TRIAL BY JURY.  THE PARTIES TO THIS AGREEMENT
            --------------------------------                                
ACKNOWLEDGE THAT JURY TRIALS OFTEN ENTAIL ADDITIONAL EXPENSES AND DELAYS NOT
OCCASIONED BY NONJURY TRIALS.  THE PARTIES TO THIS AGREEMENT AGREE AND STIPULATE

OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS

FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO
TRIAL BY JURY.

          IN WITNESS WHEREOF, this Agreement has been duly executed as of the

<PAGE>
 
                                LOAN AGREEMENT

          The undersigned EDUCATIONAL INDUSTRIAL SALES INCORPORATED
("Borrower"), for value received, hereby promises to pay to SAND HILL CAPITAL
LLC ("Sand Hill") at such place as Sand Hill may specify, in lawful money of the
United States of America, (i) the principal amount of $1,020,000 or, if lower,
(ii) the principal amount of all outstanding advances ("Advances") that Sand
Hill makes hereunder, plus interest on the principal amount hereof from time to
time outstanding at a rate equal to the rate per annum specified on the cover
page.  Interest shall be payable on the first day of each month, beginning the
month following the date of this Agreement and continuing through the Maturity
Date specified on the cover page.  The entire principal balance and all accrued
interest shall be immediately due and payable on the Maturity Date.


     1.   Advance Requests; Payments. Borrower may request an Advance from time
          --------------------------        
to time at any time after Borrower's receipt of not less than $1,000,000 from
the sale or issuance of its equity securities after the date hereof on terms
reasonably acceptable to Sand Hill (the "Wedbush Transaction"), upon one
business day's prior notice to Sand Hill, provided the representations contained
in this Agreement are true on such date and Borrower is in compliance with the
terms of this Agreement. All Advances made by Sand Hill to Borrower pursuant to
this Agreement shall be recorded by Sand Hill on the books and records of Sand
Hill. The failure of Sand Hill to record any Advance or any prepayment or
payment made on account of the principal balance hereof shall not limit or
otherwise affect the obligation of Borrower under this Agreement to pay the
principal, interest and other amounts due and payable under this Agreement.
Amounts repaid hereunder may be reborrowed through the Maturity Date.

          All payments on this Agreement shall be applied first to fees and
expenses, then to interest and then to principal.  Any principal or interest
payments on this Agreement outstanding after the occurrence and during the
continuance of a default under this Agreement shall bear interest at a rate
equal to Five Percent above the rate otherwise applicable under this Agreement.


     2.   Secured Agreement. To secure repayment of all obligations evidenced by
          -----------------
this Agreement and performance of all of Borrower's obligations hereunder,
Borrower grants Sand Hill a security interest in the property described in
Exhibit A attached hereto (the "Collateral"). Borrower shall take such actions
- ---------                                                                      
as Sand Hill requests from time to time to perfect or continue the security
interest granted hereunder. Borrower shall not dispose of or encumber all or any
substantial part of the Collateral without Sand Hill's prior written consent,
other than inventory in the ordinary course of business.


     3.   Representations and Warranties.  Borrower represents to Sand Hill as
          ------------------------------                                      
follows:  (a) Except for Borrower's failure to comply with the leverage covenant
contained in Section V.9(b) of that certain letter agreement dated as of June
16, 1997, as amended by that certain letter agreement dated March 1, 1998, each
between borrower and Wells Fargo Bank (the "Wells Agreement"), and for any
default arising thereunder by virtue of restrictions contained in such agreement
on the security interest to be granted in the Collateral to Sand Hill, Borrower
is not in default under any agreement under which Borrower owes any money, or
any agreement, the violation or termination of which could have a material
adverse effect on Borrower, (b) Borrower has taken all action necessary to
authorize the execution, delivery and performance of this Agreement; (c) except
for purchase money security interests on particular items of equipment and
inventory and for a blanket lien under the Wells Agreement, there are no liens,
security interests or other encumbrances on the Collateral; (d) the execution
and performance of this Agreement do not conflict with, or constitute a default
under, any agreement to which Borrower is party or by which Borrower is bound,
other than the Wells Agreement; (e) the
<PAGE>
 
information provided to Sand Hill on or prior to the date of this Agreement is
true and correct in all material respects; (f) all financial statements and

condition of Borrower since the date of the most recent of the financial
statements submitted to Sand Hill; (g) Borrower is in compliance with all laws
and orders applicable to it; (h) except as otherwise noted above, the Wells
Agreement is in full force and effect in the form attached hereto, there are no
defaults under the Wells Agreement, and $6,398,205.86 is outstanding under the
Wells Agreement as of June 24, 1998; and (i) no representation or other
statement made by Borrower to Sand Hill contains any untrue statement of a
material fact or omits to state a material fact necessary to make any statements
made to Sand Hill not misleading.

     4.   Covenants. (a) Borrower will provide Sand Hill: monthly company-
          --------- 
prepared financial statements within 30 days after the end of each month; and
such other financial reports and other information as Sand Hill may reasonably
request from time to time.


          (b)  Borrower will maintain insurance on the Collateral that includes
a lender's loss payable endorsement in favor of Sand Hill as an additional loss
payee. Borrower will maintain insurance in a form acceptable to Sand Hill
relating to the Collateral and Borrower's business in amounts and of a type that
are customary to businesses similar to Borrower's.

          (c)  Borrower will maintain its corporate existence and good standing
and will maintain in force all licenses and agreements, the loss of which could
have a material adverse effect on Borrower's business. Borrower will comply with
all laws and orders, the violation of which could have a material adverse effect
on Borrower's business.

          (d)  Borrower will not incur additional indebtedness for borrowed
money, or make any investments (unless Sand Hill has a second priority security
interest in the assets acquired or investments made), or make any distributions
on account of any equity interest held in Borrower, or redeem any equity
interest in Borrower, or repay any subordinated debt, without Sand Hill's prior
written consent. Except for the security interests in favor of Wells Fargo Bank
(including any financial institution or lender that refinances the credit
facility related to the Wells Agreement) and Colorado Business Leasing
Incorporated, Borrower will cause all security interests granted in its personal
property to be terminated within forty-five (45) days of the date of this
Agreement.


     5.   Fees and Expenses. Borrower shall pay Sand Hill the Facility Fee
          -----------------

warrant to purchase stock to Sand Hill in a form acceptable to Sand Hill.

          ---------------------------                         
part of the principal or interest hereunder on the date due and payable, (ii) to
comply with any agreement or covenant set forth in this Agreement, (iii) to
comply with the terms of the Wells Agreement or any

material contract to which Borrower is a party or any agreement pursuant to
which Borrower has incurred indebtedness, or (iv) to comply with any law to
which Borrower is subject which noncompliance has a material adverse effect on
the Borrower, or the occurrence of a material adverse change in the financial or
other condition of Borrower, or the exercise by Wells Fargo Bank of any remedies
available under the Wells Agreement, including without limitation the
institution of any foreclosure proceedings involving any Collateral, shall
constitute a default under this Agreement. Upon the occurrence of a default
under (i) above, or under (ii) through (iv) above and Borrower's failure to cure
any default that is capable of being cured within ten (10) days after written
notice from Sand Hill, all unpaid principal, accrued interest and other amounts
owing hereunder shall, at the option of Sand Hill, be immediately due and
payable, and Sand Hill may exercise all of the rights of a secured party under
the California Uniform Commercial Code. Sand Hill shall have a right to dispose
of the Collateral in any commercially reasonable manner, and shall have a
royalty-free license to use any name, trademark, advertising matter or any
property of a similar nature to complete production of, advertisement for, and

harmless from any claim, obligation or liability (including without limitation
reasonable attorneys fees and expenses) arising out of this Agreement or the

          -------------

($179,085.24).  The outstanding balance on this Note shall bear interest at an
annual rate of seven percent (7%).  This Note is issued pursuant to the terms of
that certain Asset Purchase Agreement dated as of June 12, 1998, the terms and
conditions of which Asset Purchase Agreement are incorporated fully herein by
this reference.  Unless otherwise defined herein, defined terms shall have the
meanings as set forth in the Asset Purchase Agreement.

        All interest is calculated daily and shall be paid based upon a 360-day
year.

FORM OF PAYMENT:
- --------------- 

        Any and all payments of any nature made or required to be made under
this Note shall be made in lawful money of the United States collectable on the
date of payment as provided in the Asset Purchase Agreement.

SUBORDINATION:
- ------------- 

        (a) The Seller agrees that the indebtedness evidenced by this Note is
subordinated in right of payment, to the extent and in the manner provided
herein, to the prior payment in full of all Senior Debt, and that the
subordination is for the benefit of the holders of Senior Debt.

        (b) For the purposes of this Note, the following definitions shall
apply:

        (1) "Debt" of any person means any indebtedness, contingent or
             ----                                                     
        otherwise, in respect of borrowed money (whether or not the recourse of
        the lender is to the whole of the assets of such person or only to a
        portion thereof), or evidenced by bonds, notes, debentures or similar
        instruments or letters of credit, or representing the balance deferred
        and unpaid of the purchase price of any property or interest therein,
        except any such balance that constitutes a trade payable, if and to the
        extent such indebtedness would appear as a liability upon a balance
        sheet of such person prepared on a consolidated basis in accordance with
        generally accepted accounting principles.


<PAGE>
 
        (2) "Senior Debt" means all Debt (present or future) created,
             -----------                                             
        incurred, assumed or guaranteed by EIS (and all renewals, extensions or
        refundings thereof) with Wells Fargo Bank or any successor or
        replacement lender, unless the instrument under which such Debt is
        created, incurred, assumed or guaranteed expressly provides that such
        Debt is not senior or superior in right of payment to the Seller.

        (c) Upon any distribution to creditors of EIS in a liquidation or
dissolution of EIS or in a bankruptcy, reorganization, insolvency, receivership
or similar proceeding relating to EIS or its property, holders of Senior Debt
shall be entitled to receive payment in full in cash of the principal of and
interest (including interest accruing after the commencement of any such
proceeding) to the date of payment on the Senior Debt before Seller shall be
entitled to receive any payment of principal of or interest on the Note.

        (d) Upon the final maturity of any Senior Debt by lapse of time,
acceleration or otherwise, all such Senior Debt shall first be paid in full, or
such payment duly provided for in cash or in a manner satisfactory to the
holders of such Senior Debt, before any payment is made by EIS or any person
acting on behalf of EIS on account of the principal or interest of the Note.

        (e) EIS may not pay principal of or interest on the Note if:

        (1) a default on Senior Debt occurs and is continuing that permits
        holders of such Senior Debt to accelerate its maturity, and

        (2) the default is the subject of judicial proceedings or EIS receives a
        notice of the default from a person who holds Senior Debt. If EIS
        receives any such notice, a subsequent notice received within nine
        months thereafter relating to the same issue of Senior Debt shall not be
        effective for purposes of this provision.

        (f) EIS shall resume payments on the Note and may acquire the Note when:

        (1) the default is cured or waived, or

        (2) 120 days pass after the notice is given if the default is not the
        subject of judicial proceedings,

if this Note otherwise permits the payment or acquisition at that time.

        (g) If payment of the Note is accelerated because of an Event of
Default, EIS shall promptly notify holders of Senior Debt of the acceleration.
EIS shall pay the Note when 120 days pass after the acceleration occurs if the
Note permits the payment at that time; provided, however, that if no Senior Debt
is outstanding at the time of such acceleration EIS shall pay the Note in
accordance with the provisions of this Note.

        (h) If a payment is made to the Seller that because of this
subordination provision should not have been made to them, the Seller shall hold
such payment in trust for holders of 


<PAGE>
 
Senior Debt and pay it over to them as their interests may appear; provided,
however, that if neither EIS nor the holders of the Senior Debt notify the
Seller within 120 days after the payment is made that such payment should not
have been made, the Seller shall no longer be deemed to be holding such payment
in trust pursuant to this subsection (h).

        (i) This subordination provision defines the relative rights of Seller
and holders of Senior Debt.  Nothing in this provision shall:

        (1) impair, as between EIS and Seller, the obligation of EIS, which is
        absolute and unconditional, to pay principal of and interest on the Note
        in accordance with its terms;

        (2) affect the relative rights of Seller and creditors of EIS other
        than holders of Senior Debt; or

        (3) prevent Seller from exercising their available remedies upon a
        Default or Event of Default, subject to the rights of holders of Senior
        Debt to receive payments otherwise payable to Seller.

        (j) If EIS fails because of this subordination provision to pay
principal of or interest on the Note on the due date, the failure is still a
Default or Event of Default.

        (k) No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by the Note shall be impaired by any act or
failure to act by EIS or by its failure to comply with this subordination
provision.

- ----------------------- 

        Payments shall be applied first to interest and the remainder to the
principal balance.  Payments, if less than the amount required, shall be applied

waiver of the rights of the holder hereof to require scheduled payments.

        This Note may not be prepaid prior to December 31, 1999 and may only be
prepaid thereafter if the Seller has not timely exercised the Conversion Option.
Any permitted prepayment shall be applied to the last principal due hereunder

($179,085.24).  The outstanding balance on this Note shall bear interest an
annual rate of seven percent (7%).  This Note is issued pursuant to the terms of
that certain Asset Purchase Agreement dated as of June 12, 1998, the terms and
conditions of which Asset Purchase Agreement are incorporated fully herein by
this reference.  Unless otherwise defined herein, defined terms shall have the
meanings as set forth in the Asset Purchase Agreement.

        All interest is calculated daily and shall be paid based upon a 360-day
year.

FORM OF PAYMENT:
- --------------- 

        Any and all payments of any nature made or required to be made under
this Note shall be made in lawful money of the United States collectable on the
date of payment as provided in the Asset Purchase Agreement.

SUBORDINATION:
- ------------- 

        (a) The Seller agrees that the indebtedness evidenced by this Note is
subordinated in right of payment, to the extent and in the manner provided
herein, to the prior payment in full of all Senior Debt, and that the
subordination is for the benefit of the holders of Senior Debt.

        (b) For the purposes of this Note, the following definitions shall
apply:

        (1) "Debt" of any person means any indebtedness, contingent or
             ----
        otherwise, in respect of borrowed money (whether or not the recourse of
        the lender is to the whole of the assets of such person or only to a
        portion thereof), or evidenced by bonds, notes, debentures or similar
        instruments or letters of credit, or representing the balance deferred
        and unpaid of the purchase price of any property or interest therein,
        except any such balance that constitutes a trade payable, if and to the
        extent such indebtedness would appear as a liability upon a balance
        sheet of such person prepared on a consolidated basis in accordance with
        generally accepted accounting principles.

<PAGE>
 
        (2) "Senior Debt" means all Debt (present or future) created, incurred,
             -----------                                                       
        assumed or guaranteed by EIS (and all renewals, extensions or refundings
        thereof) with Wells Fargo Bank or any successor or replacement lender,
        unless the instrument under which such Debt is created, incurred,
        assumed or guaranteed expressly provides that such Debt is not senior or
        superior in right of payment to the Seller.

        (c) Upon any distribution to creditors of EIS in a liquidation or
dissolution of EIS or in a bankruptcy, reorganization, insolvency, receivership
or similar proceeding relating to EIS or its property, holders of Senior Debt
shall be entitled to receive payment in full in cash of the principal of and
interest (including interest accruing after the commencement of any such
proceeding) to the date of payment on the Senior Debt before Seller shall be
entitled to receive any payment of principal of or interest on the Note.

        (d) Upon the final maturity of any Senior Debt by lapse of time,
acceleration or otherwise, all such Senior Debt shall first be paid in full, or
such payment duly provided for in cash or in a manner satisfactory to the
holders of such Senior Debt, before any payment is made by EIS or any person
acting on behalf of EIS on account of the principal or interest of the Note.

        (e) EIS may not pay principal of or interest on the Note if:

        (1) a default on Senior Debt occurs and is continuing that permits
        holders of such Senior Debt to accelerate its maturity, and

        (2) the default is the subject of judicial proceedings or EIS receives a
        notice of the default from a person who holds Senior Debt. If EIS
        receives any such notice, a subsequent notice received within nine
        months thereafter relating to the same issue of Senior Debt shall not be
        effective for purposes of this provision.

        (f) EIS shall resume payments on the Note and may acquire the Note when:

        (1)  the default is cured or waived, or

        (2) 120 days pass after the notice is given if the default is not the
        subject of judicial proceedings,

if this Note otherwise permits the payment or acquisition at that time.

        (g) If payment of the Note is accelerated because of an Event of
Default, EIS shall promptly notify holders of Senior Debt of the acceleration.
EIS shall pay the Note when 120 days pass after the acceleration occurs if the
Note permits the payment at that time;  provided, however, that if no Senior
Debt is outstanding at the time of such acceleration EIS shall pay the Note in
accordance with the provisions of this Note.

        (h) If a payment is made to the Seller that because of this
subordination provision should not have been made to them, the Seller shall hold
such payment in trust for holders of 

<PAGE>
 
Senior Debt and pay it over to them as their interests may appear; provided,
however, that if neither EIS nor the holders of the Senior Debt notify the
Seller within 120 days after the payment is made that such payment should not
have been made, the Seller shall no longer be deemed to be holding such payment
in trust pursuant to this subsection (h).

        (i) This subordination provision defines the relative rights of Seller
and holders of Senior Debt.  Nothing in this provision shall:

        (1) impair, as between EIS and Seller, the obligation of EIS, which is
        absolute and unconditional, to pay principal of and interest on the Note
        in accordance with its terms;

        (2) affect the relative rights of Seller and creditors of EIS other than
        holders of Senior Debt; or

        (3) prevent Seller from exercising their available remedies upon a
        Default or Event of Default, subject to the rights of holders of Senior
        Debt to receive payments otherwise payable to Seller.

        (j) If EIS fails because of this subordination provision to pay
principal of or interest on the Note on the due date, the failure is still a
Default or Event of Default.

        (k) No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by the Note shall be impaired by any act or
failure to act by EIS or by its failure to comply with this subordination
provision.

CONVERSION OPTION:
- ----------------- 

        At any time after the Closing Date and prior to December 31, 1999 (the
"Final Conversion Date"), if there has been no Initial Public Offering of EIS's
common stock the Seller shall have the right, on written notice to EIS to
convert this Note into common stock of EIS (the "Conversion Option").  If there
has been an Initial Public Offering of EIS's common stock prior to the Final
Conversion Date, this Note shall automatically be canceled and converted into
EIS common stock on the date immediately following the Initial Public Offering
(the "Mandatory Conversion").  If the Seller timely elects the Conversion Option
or there is a Mandatory Conversion, this Note shall be exchanged for FIVE
THOUSAND NINE HUNDRED EIGHTY TWO (5,982) shares of common stock in EIS.  The EIS
common stock issued pursuant to either conversion shall be subject to the same
limitations and restriction as the common stock held by the other principal
shareholders of EIS.

REQUIRED PAYMENTS AND LOAN MATURITY:
- ----------------------------------- 

        If there has been no Mandatory Conversion or the Seller fails to timely
exercise the Conversion Option, this Note shall be paid in six (6) equal monthly
installments of principal and interest on the unpaid principal amount by 5:00
p.m. commencing on the first business day of January 2000 and on the first
business day of every month thereafter until June 2000 when the 

<PAGE>
 
principal balance hereof and all accrued and unpaid interest hereunder is paid
in full. If EIS fails to make any payment when due, then Seller shall have the
option, to be exercised in its sole and absolute discretion, to accelerate the
payments due hereunder and declare the unpaid principal amount and all accrued
and unpaid interest immediately due and payable.

LATE CHARGE:
- ----------- 

        If any payment required hereunder is not received by holder when due,
a late charge of five percent (5.0%) of each overdue required payment shall be
charged for the purpose of defraying the expenses incident to handling said
delinquent payment(s).

APPLICATION OF PAYMENTS:
- ----------------------- 

        Payments shall be applied first to interest and the remainder to the
principal balance.  Payments, if less than the amount required, shall be applied
in the sole discretion of holder and acceptance of such payments shall not be a
waiver of the rights of the holder hereof to require scheduled payments.

VOLUNTARY PREPAYMENT CLAUSE:
- --------------------------- 

        This Note may not be prepaid prior to December 31, 1999 and may only
be prepaid thereafter if the Seller has not timely exercised the Conversion
Option.  Any permitted prepayment shall be applied to the last principal due
hereunder and no such prepayment shall affect or reduce the amount of any
scheduled payments hereunder.

RIGHT OF SET-OFF:
- ---------------- 

        EIS shall have the right to withhold and set-off against any amount
due hereunder the amount of any claim for indemnification or payment of damages
to which EIS may be entitled as a result of Seller's or the Seller's
Stockholder's breach of the provisions in the Asset Purchase Agreement and/or
the Agreement of Seller Stockholders.

          apply:

          (1) "Debt" of any person means any indebtedness, contingent or
          otherwise, in respect of borrowed money (whether or not the recourse

          similar instruments or letters of credit, or representing the balance
          deferred and unpaid of the purchase price of any property or interest

          (c) Upon any distribution to creditors of EIS in a liquidation or

such payment in trust for holders of Senior Debt and pay it over to them as
their interests may appear;  provided, however, that if neither EIS nor the
holders of the Senior Debt notify the Seller within 120 days after the payment
is made that such payment should not have been made, the Seller shall no longer
be deemed to be holding such payment in trust pursuant to this subsection (h).

and holders of Senior Debt.  Nothing in this provision shall:

          (1) impair, as between EIS and Seller, the obligation of EIS, which is

Default or Event of Default.

          similar instruments or letters of credit, or representing the balance
          deferred and unpaid of the purchase price of any property or interest
          therein, except any such balance that constitutes a trade payable, if
          and to the extent such indebtedness would appear as a liability upon a
          balance sheet of such person prepared on a consolidated basis in
          accordance with generally accepted accounting principles.

              (2) "Senior Debt" means all Debt (present or future) created,
                   -----------                                             
          incurred, assumed or guaranteed by EIS (and all renewals, extensions
          or refundings thereof) with Wells Fargo Bank or any successor or
          replacement lender, unless the instrument under which such Debt is
          created, incurred, assumed or guaranteed expressly provides that such
          Debt is not senior or superior in right of payment to the Seller.

          (c) Upon any distribution to creditors of EIS in a liquidation or
dissolution of EIS or in a bankruptcy, reorganization, insolvency, receivership
or similar proceeding relating to EIS or its property, holders of Senior Debt
shall be entitled to receive payment in full in cash of the principal of and
interest (including interest accruing after the commencement of any such
proceeding) to the date of payment on the Senior Debt before Seller shall be
entitled to receive any payment of principal of or interest on the Note.

          (d) Upon the final maturity of any Senior Debt by lapse of time,
acceleration or otherwise, all such Senior Debt shall first be paid in full, or
such payment duly provided for in cash or in a manner satisfactory to the
holders of such Senior Debt, before any payment is made by EIS or any person
acting on behalf of EIS on account of the principal or interest of the Note.

          (e) EIS may not pay principal of or interest on the Note if:

              (1) a default on Senior Debt occurs and is continuing that
          permits holders of such Senior Debt to accelerate its maturity, and

<PAGE>
 
              (2) the default is the subject of judicial proceedings or EIS
          receives a  notice of the default from a person who holds Senior Debt.
          If EIS receives any such notice, a subsequent notice received within
          nine months thereafter relating to the same issue of Senior Debt shall
          not be effective for purposes of this provision.

          (f) EIS shall resume payments on the Note and may acquire the Note
when:

              (1) the default is cured or waived, or

              (2) 120 days pass after the notice is given if the default is not
                  the subject of judicial proceedings,

if this Note otherwise permits the payment or acquisition at that time.

          (g) If payment of the Note is accelerated because of an Event of
Default, EIS shall promptly notify holders of Senior Debt of the acceleration.
EIS shall pay the Note when 120 days pass after the acceleration occurs if the
Note permits the payment at that time; provided, however, that if no Senior Debt
is outstanding at the time of such acceleration EIS shall pay the Note in
accordance with the provisions of this Note.

          (h) If a payment is made to the Seller that because of this
subordination provision should not have been made to them, the Seller shall hold
such payment in trust for holders of Senior Debt and pay it over to them as
their interests may appear; provided, however, that if neither EIS nor the
holders of the Senior Debt notify the Seller within 120 days after the payment
is made that such payment should not have been made, the Seller shall no longer
be deemed to be holding such payment in trust pursuant to this subsection (h).

          (i) This subordination provision defines the relative rights of Seller
and holders of Senior Debt.  Nothing in this provision shall:

              (1) impair, as between EIS and Seller, the obligation of EIS,
          which is absolute and unconditional, to pay principal of and interest
          on the Note in accordance with its terms;

              (2) affect the relative rights of Seller and creditors of EIS
          other than holders of Senior Debt; or

              (3) prevent Seller from exercising their available remedies upon
          a Default or Event of Default, subject to the rights of holders of
          Senior Debt to receive payments otherwise payable to Seller.

<PAGE>
 
          (j) If EIS fails because of this subordination provision to pay
principal of or interest on the Note on the due date, the failure is still a
Default or Event of Default.

          (k) No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by the Note shall be impaired by any act or
failure to act by EIS or by its failure to comply with this subordination
provision.

                                                                 August 24, 1998

          For Value Received, the undersigned ELECTRONIC INTEGRATED SOLUTIONS
(formerly known as EIS, INC.) ("EIS") promises to pay to the order of DIGITAL

($133,333.34).  This Note is issued pursuant to the terms of that certain Asset
Purchase Agreement dated as of June 12, 1998, the terms and conditions of which
Asset Purchase Agreement are incorporated fully herein by this reference.
Unless otherwise defined herein, defined terms shall have the meanings as set
forth in the Asset Purchase Agreement.

          The undersigned promises to pay interest on the principal amount
hereof remaining unpaid from time to time at the Applicable Rate.

          All interest is calculated daily and shall be paid based upon a 360-
day year.

APPLICABLE RATE:
- ----------------

          "Applicable Rate" shall mean, for any day, a fluctuating rate of
interest equal to the rate of interest publicly announced from time to time by
Wells Fargo Bank ("Bank"), or its successor, in San Francisco, California as its
reference rate.  It is a rate set by Bank based upon various factors, including
its costs and desired return, general economic conditions and other factors, and
is used as a reference point for pricing some loans, which may be priced at,
above or below such announced rate.

- ----------------

          Any and all payments of any nature made or required to be made under
this Note shall be made in lawful money of the United States collectable on the

SUBORDINATION:
- --------------

          (a) The Seller agrees that the indebtedness evidenced by this Note is
subordinated in right of payment, to the extent and in the manner provided
herein, to the prior payment in full of all Senior Debt, and that the
subordination is for the benefit of the holders of Senior Debt.

          (b) For the purposes of this Note, the following definitions shall
apply:

          (1) "Debt" of any person means any indebtedness, contingent or
          otherwise, in respect of borrowed money (whether or not the recourse
          of the lender is to the whole of the assets of such person or only to
          a portion thereof), or evidenced by bonds, notes, debentures or
          similar instruments or letters of credit, or representing the balance
          deferred and unpaid of the purchase price of any property or interest
          therein, except any such balance that constitutes a trade payable, if
          and to the extent such indebtedness would appear as a liability upon a
          balance sheet of such person prepared on a consolidated basis in
          accordance with generally accepted accounting principles.

          (2) "Senior Debt" means all Debt (present or future) created,
          incurred, assumed or guaranteed by EIS (and all renewals, extensions
          or refundings thereof) with Wells Fargo Bank or any successor or
          replacement lender, unless the instrument under which such Debt is
          created, incurred, assumed or guaranteed expressly provides that such
          Debt is not senior or superior in right of payment to the Seller.

          (c) Upon any distribution to creditors of EIS in a liquidation or
dissolution of EIS or in a bankruptcy, reorganization, insolvency, receivership
or similar proceeding relating to EIS or its property, holders of Senior Debt
shall be entitled to receive payment in full cash of the principal of and
interest (including interest accruing after the commencement of any such
proceeding) to the date of payment on the Senior Debt before Seller shall be
entitled to receive any payment of principal of or interest on the Note.

          (d) Upon the final maturity of any Senior Debt by lapse of time,
acceleration or otherwise, all such Senior Debt shall first be paid in full, or
such payment duly provided for in cash or in a manner satisfactory to the
holders of such Senior Debt, before any payment is made by EIS or any person
acting on behalf of EIS on account of the principal or interest of the Note.

          (e) EIS may not pay principal of or interest on the Note if:

          (1)  a default on Senior Debt occurs and is continuing that permits
          holders of such Senior Debt to accelerate its maturity, and

<PAGE>
 
          (2) the default is the subject of judicial proceedings or EIS receives
          a notice of the default from a person who holds Senior Debt. If EIS
          receives any such notice, a subsequent notice received within nine
          months thereafter relating to the same issue of Senior Debt shall not
          be effective for purposes of this provision.

          (f) EIS shall resume payments on the Note and may acquire the Note
when:

          (1) the default is cured or waived, or

          (2) 120 days pass after the notice is given if the default is not the
          subject of judicial proceedings,

if this Note otherwise permits the payment or acquisition at that time.

          (g) If payment of the Note is accelerated because of an Event of
Default, EIS shall promptly notify holders of Senior Debt of the acceleration.
EIS shall pay the Note when 120 days pass after the acceleration occurs if the
Note permits the payment at that time;  provided, however, that if no Senior
Debt is outstanding at the time of such acceleration EIS shall pay the Note in
accordance with the provisions of this Note.

          (h) If a payment is made to the Seller that because of this
subordination provision should not have been made to them, the Seller shall hold
such payment in trust for holders of Senior Debt and pay it over to them as
their interests may appear;  provided, however, that if neither EIS nor the
holders of the Senior Debt notify the Seller within 120 days after the payment
is made that such payment should not have been made, the Seller shall no longer
be deemed to be holding such payment in trust pursuant to this subsection (h).

          (i) This subordination provision defines the relative rights of Seller
and holders of Senior Debt.  Nothing in this provision shall:

          (1) impair, as between EIS and Seller, the obligation of EIS, which is
          absolute and unconditional, to pay principal of and interest on the
          Note in accordance with its terms;

          (2) affect the relative rights of Seller and creditors of EIS other
          than holders of Senior Debt; or

          (3) prevent Seller from exercising their available remedies upon a
          Default or Event of Default, subject to the rights of holders of
          Senior Debt to receive payments otherwise payable to Seller.

          (j) If EIS fails because of this subordination provision to pay
principal of or interest on the Note on the due date, the failure is still a
Default or Event of Default.

<PAGE>
 
          (k) No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by the Note shall be impaired by any act or
failure to act by EIS or by its failure to comply with this subordination
provision.

REQUIRED PAYMENTS AND LOAN MATURITY:
- ------------------------------------

          The principal balance hereof and all accrued and unpaid interest
hereunder shall be paid in full on or before six (6) months after the Closing
Date.

LATE CHARGE:

          If any payment required hereunder is not received by holder when due,
a late charge of five percent (5.0%) of each overdue required payment shall be
charged for the purpose of defraying the expenses incident to handling said
delinquent payment(s).

APPLICATION OF PAYMENTS:
- ------------------------

          Payments shall be applied first to interest and the remainder to the
principal balance.  Payments, if less than the amount required, shall be applied
in the sole discretion of holder and acceptance of such payments shall not be a
waiver of the rights of the holder hereof to require scheduled payments.

          This Note may be prepaid at any time in whole or in part.

RIGHT OF SET-OFF:
- -----------------

          EIS shall have the right to withhold and set-off against any amount

Stockholder's breach of the provisions in the Asset Purchase Agreement and/or
the Agreement of Seller Stockholders.

COSTS:
- ------

          permits holders of such Senior Debt to accelerate its maturity, and

              (2) the default is the subject of judicial proceedings or EISI
          receives a notice of the default from a person who holds Senior Debt.
          If EISI receives any such notice, a subsequent notice received within
          nine months thereafter relating to the same issue of Senior Debt shall
          not be effective for purposes of this provision.

          (f) EISI shall resume payments on the Note and may acquire the Note
when:

              (1) the default is cured or waived, or

              (2) 120 days pass after the notice is given if the default is not
          the subject of judicial proceedings,

if this Note otherwise permits the payment or acquisition at that time.

                                       2
<PAGE>
 
          (g) If payment of the Note is accelerated because of an Event of
Default, EISI shall promptly notify holders of Senior Debt of the acceleration.
EISI shall pay the Note when 120 days pass after the acceleration occurs if the
Note permits the payment at that time; provided, however, that if no Senior Debt
is outstanding at the time of such acceleration EISI shall pay the Note in
accordance with the provisions of this Note.

          (h) If a payment is made to the Seller that because of this
subordination provision should not have been made to them, the Seller shall hold
such payment in trust for holders of Senior Debt and pay it over to them as
their interests may appear.

          (i) This subordination provision defines the relative rights of Seller
and holders of Senior Debt.  Nothing in this provision shall:

              (1) impair, as between EISI and Seller, the obligation of EISI,
          which is absolute and unconditional, to pay principal of and interest
          on the Note in accordance with its terms;

              (2) affect the relative rights of Seller and creditors of EISI
          other than holders of Senior Debt; or

              (3) prevent Seller from exercising their available remedies upon
          a Default or Event of Default, subject to the rights of holders of
          Senior Debt to receive payments otherwise payable to Seller.

          (j) If EISI fails because of this subordination provision to pay
principal of or interest on the Note on the due date, the failure is still a
Default or Event of Default.

          (k) No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by the Note shall be impaired by any act or
failure to act by EISI or by its failure to comply with this subordination
provision.

REQUIRED PAYMENTS AND LOAN MATURITY:
- ------------------------------------

          The principal amount shall be due and payable on January 2, 1999 or
the day immediately following an Initial Public Offering of EISI's common stock,
whichever is earlier, unless EISI elects the Buyer Note Installment Payment
Option.  If EISI elects the Buyer Note Installment Payment Option, equal monthly
installments of principal in the amount of Five Hundred Thousand Dollars
($500,000) and interest on the unpaid principal amount shall be paid by EISI by
5:00 p.m. with the first payment to be made on February 1, 1999 and continuing
every month thereafter until July 1, 1999 when the principal balance hereof and
all accrued and unpaid interest hereunder is paid in full.  If EISI fails to
make any payment when due, then Seller shall have the option, to be exercised in
its sole and absolute discretion, to accelerate the payments due hereunder and
declare the unpaid principal amount and all accrued and unpaid interest
immediately due and payable.

                                       3
<PAGE>
 
LATE CHARGE:
- ------------

          If any payment required hereunder is not received by holder when due,
a late charge of five percent (5.0%) of each overdue required payment shall be
charged for the purpose of defraying the expenses incident to handling said
delinquent payment(s).

APPLICATION OF PAYMENTS:
- ------------------------

          Payments shall be applied first to interest and the remainder to the
principal balance.  Payments, if less than the amount required, shall be applied
in the sole discretion of holder and acceptance of such payments shall not be a
waiver of the rights of the holder hereof to require scheduled payments.

VOLUNTARY PREPAYMENT CLAUSE:
- ----------------------------

          This Note may be prepaid at any time in whole or in part; provided,
that any such prepayment shall be applied to the last principal due hereunder
and no such prepayment shall affect or reduce the amount of any scheduled
payments hereunder.

RIGHT OF SET-OFF:
- -----------------

          EISI shall have the right to withhold and set-off against any amount
due hereunder the amount of any claim for indemnification or payment of damages
to which EISI may be entitled as a result of Seller's breach of the provisions
in the Stock Purchase Agreement.

DEFAULT OF TERMS AND CONDITIONS:
- --------------------------------

          It is agreed that time is of the essence of this Note and that in the
event of default of payment of any installment, the holder of this Note may, at
its option, declare all the remainder of said debt due and payable, and any
failure to exercise said option shall not constitute a waiver of the right to
exercise the same at any other time, nor shall such failure to exercise the
option be construed as any form of acceptance of any said default.  Notice of
the exercise of said option is hereby waived.

COSTS:
- ------

          Undersigned agrees to reimburse holder for all costs and expenses,
including, without limitation, all reasonable attorneys' fees incurred in the
enforcement or collection of this Note or any judgment obtained hereon.

LAWS:

accordance with, the laws of the State of California applicable to contracts
made and performed in such state, without regard to the principles thereof

<PAGE>
 
          2.  IMPLEMENTATION PLANNING.

          FRC shall assist Client to design and implement a written
implementation plan which identifies the order of the Dynamics SQL modules to be
installed at the Client's principal place of business, the necessary testing for
each module, the parallel processes/tasks that need to be run, and the training
plan for the client's staff.

          3.  NETWORK SYSTEM REVIEW.

          FRC shall assist Client to perform a systematic review of the
hardware, software and operating system components and shall document the
findings. FRC shall assist Client to correct all deficiencies identified in the
review before implementing client/server applications. The parties agree that
this approach should minimize problems both before and after implementation.

          A typical systematic review of the hardware, software and operating
system components includes a review of the following: critical server
initialization files, volume analysis, access and security issues, network
operating system library and driver files, client operating systems and network
shell files, workstation performance, memory, and volume issues, software
management program, virus protection, backup strategies and procedures


          4.  INSTALLATION AND SETUP.

          FRC shall assist Client to install the Great Plains Dynamics SQL
modules onto Client's server. FRC shall initialize the database so that Client
will have a starting point for setting up the Client data designed around the
Client's needs. FRC shall then assist Client to configure all of the Client's
workstations that Client requires be accessible to the Great Plains Dynamics SQL
modules.


          5.  DATA CONVERSION.

FRC shall assist Client to convert the Client's existing accounting data into
Great Plains Dynamics SQL modules. Some of this may be accomplished
electronically and some may be accomplished manually.



          6.  MODULE IMPLEMENTATION AND TRAINING.

          FRC shall assist Client to install and set up the Dynamics SQL
modules. FRC shall work with the Client to identify and create a coding scheme
for master records (chart of accounts, vendors, customers, etc.) that is
acceptable to Client and shall assist the Client in setting up the master
records. FRC shall train the Client's staff to use the Dynamics SQL modules.
This training shall include how to enter data, perform key processes, print
needed reports and close the modules.

in the Project Scope of this Agreement or the consulting fee estimate.


          8.  SYSTEM IMPLEMENTATION AND TEST.

          FRC shall assist Client to plan, design and document procedures for
testing, training, system test, data conversion and post cutover follow up. FRC
shall train Client's staff computer professionals in the testing procedures. In
order for the system implementation and testing procedures to be effective, FRC
requires Client to communicate its objectives to make Client's staff available
for frequent status and design meetings with the Client to confirm findings and
project approach and to facilitate the decision process on the numerous issues
that will surface.


                       ARTICLE II.  -  CLIENT COOPERATION

          Client shall assist FRC by promptly providing such equipment necessary
for FRC's Employees to render the Services in a manner which conforms to FRC's
standard practices. If Client is unable to provide such equipment, FRC may
acquire such equipment and add the acquisition cost to its bill to Client.
Client shall also promptly provide information and access to the facilities of
Client to FRC as FRC may reasonably request.


                       ARTICLE III.  -  PRICE AND PAYMENT


          A.  PROFESSIONAL FEES:  The fees for FRC's services will be billed as

project, plus direct expenses. These rates vary from $100 per hour for a staff

need to be documented, evaluated and incorporated in the new system. We will
gain your approval prior to incurring fees above the estimate.
