                          NOTES TO FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     Interim Financial Statements. The accompanying financial statements of
XCare.net, Inc. (the "Company") have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures normally included in financial statements prepared in
accordance with accounting principles generally accepted in the United States
have been condensed or omitted pursuant to such rules and regulations. However,
the Company believes that the disclosures are adequate to make the information
presented not misleading. The unaudited financial statements included herein
have been prepared on the same basis as the annual financial statements and
reflect all adjustments, which include only normal recurring adjustments
necessary for a fair presentation in accordance with accounting principles
generally accepted in the United States. The results for the three-month period
ended March 31, 2000 are not necessarily indicative of the results expected for
the full year. These financial statements should be read in conjunction with the
audited financial statements and notes thereto included in the Company's Annual
Report on Form 10-K for the year ended December 31, 1999.

     On February 9, 2000, the SEC declared effective the Company's Registration
Statement on Form S-1. Pursuant to this Registration Statement, the Company
completed an Initial Public Offering ("IPO") of 5,750,000 shares of its common
stock (including 750,000 shares sold pursuant to the exercise of the
underwriter's over-allotment option) at an IPO offering price of $18.00 per
share (the "Offering"). Proceeds to the Company from the Offering, after
calculation of the underwriter's discount, totaled approximately $94.2 million,
net of offering costs of approximately $2.0 million. Concurrent with the closing
of the IPO, all outstanding shares of the Company's convertible preferred stock
were automatically converted into 9,108,122 shares of common stock. In addition,
upon closing of the IPO, all outstanding common stock warrants and the Series A
convertible preferred stock warrants were exercised. The Series A convertible
preferred stock issued upon the exercise of the latter warrants was
automatically converted into common stock and together with the exercise of the
common stock warrants, resulted in the issuance of 702,924 additional shares of
common stock.

     Revenue Recognition. For contracts entered into subsequent to January 1,
1998, the Company recognizes revenue in accordance with the provisions of
Statement of Position 97-2, "Software Revenue Recognition". The Company derives
revenue from license fees and related services under the terms of fixed price
contracts. Maintenance revenue is derived from agreements for supporting and
providing periodic updates to licensed software. Consulting revenue consists of
revenue from consulting services provided pursuant to time and materials
contracts. Transaction processing revenue is derived from transaction processing
services and is recognized on a per-transaction basis as services are performed.
Operational support revenue is derived from agreements for supporting and
maintaining customers' processing environments and is recognized ratably over
the service period.

     License fees and related services revenue is generally recognized from
fixed price contracts using the percentage-of-completion method of accounting
where collectibility of fees is probable. Where collectibility of fees is not
probable, the Company defers revenue and related costs as deferred contract
costs and recognizes revenue and cost of revenue as cash is collected.

     The Company may encounter budget and schedule overruns on fixed price
contracts caused by increased material, labor or overhead costs. Adjustments to
cost estimates are made in the periods in which the facts requiring such
revisions become known. Estimated losses, if any, are recorded in the period in
which current estimates of total contract revenue and contract costs indicate a
loss. The Company does not require collateral for its receivables and an
allowance is maintained for potential credit losses.

     Maintenance revenue and operational support revenue are recorded as
unearned revenue and are recognized ratably over the service periods, which are
generally 12 months. When maintenance is bundled with the original license fee
arrangement, its fair value is deferred and recognized during the period such
services are provided.

Revenue from consulting services provided pursuant to time-and-materials
contracts is recognized as the services

are performed.
     Reclassifications. Certain prior year information has been reclassified to
conform with the current year presentation.


2. NET LOSS PER COMMON SHARE

     Net loss per common share is calculated in accordance with SFAS No. 128,
"Earnings per Share". Under the provisions of SFAS No. 128, basic net loss per
common share is computed by dividing the net loss for the period by the weighted
average number of common shares outstanding during the period. Diluted net loss
per common share is computed by dividing the net loss for the period by the
weighted average number of common and potential common shares outstanding during
the period if their effect is dilutive. Potential common shares consist of
incremental common shares issuable upon the exercise of stock options and
warrants.

     The following table sets forth the computation of the numerators and
denominators in the basic and diluted net loss per common share calculations for
the periods indicated:

3. RECENT ACCOUNTING PRONOUNCEMENTS

     The Securities and Exchange Commission issued Staff Accounting Bulletin
(SAB) No. 101, "Revenue Recognition in Financial Statements," as amended, in
December 1999 that provides further interpretive guidance for public companies.
SAB No. 101 will be effective for the Company's second quarter of 2000.
Management anticipates that the adoption of SAB No. 101 will not have a material
impact on the Company's financial condition or results of operations and that it
will not have a significant impact on its current licensing or revenue
recognition practices.

share (the "Offering"). Proceeds to the Company from the Offering, after
calculation of the underwriter's discount, totaled approximately $94.2 million,
net of offering costs of approximately $2.0 million. Concurrent with the closing
of the IPO, all outstanding shares of the Company's convertible preferred stock
were automatically converted into 9,108,122 shares of common stock. In addition,
upon closing of the IPO, all outstanding common stock warrants and the Series A
convertible preferred stock warrants were exercised. The Series A convertible
preferred stock issued upon the exercise of the latter warrants was
automatically converted into common stock and together with the exercise of the
common stock warrants, resulted in the issuance of 702,924 additional shares of
common stock.

     We recognize revenue in accordance with the provisions of Statement of
Position 97-2, "Software Revenue Recognition." We derive revenue from license
fees and related services under the terms of fixed price contracts. Maintenance
revenue is derived from agreements for supporting and providing periodic updates
to licensed software. Consulting revenue consists of revenue from consulting
services provided pursuant to time and materials contracts. Transaction
processing revenue is derived from transaction processing services and is
recognized on a per-transaction basis as services are performed. Operational
support revenue is derived from agreements for supporting and maintaining
customers' processing environments and is recognized ratably over the service
period.

     License fees and related services revenue is generally recognized from
fixed price contracts using the percentage-of-completion method of accounting
where collectibility of fees is probable. Where collectibility of fees is not
probable, we defer revenue and related costs as deferred contract costs and
recognize revenue and cost of revenue as cash is collected.

     We may encounter budget and schedule overruns on fixed price contracts
caused by increased material, labor or overhead costs. Adjustments to cost
estimates are made in the periods in which the facts requiring such revisions
become known. Estimated losses, if any, are recorded in the period in which
current estimates of total contract revenue and contract costs indicate a loss.
We do not require collateral for our receivables and an allowance is maintained
for potential credit losses.

     Maintenance revenue is recorded as unearned revenue and is recognized
ratably over the service period, which is generally 12 months. When maintenance
is bundled with the original license fee arrangement, its fair value is deferred
and recognized during the period such services are provided.

     Revenue from consulting services provided pursuant to time-and-materials
contracts is recognized as the services are performed.

     We incurred net losses and losses from operations the three months ended
March 31, 2000 and 1999. As of March 31, 2000, we had an accumulated deficit of
approximately $17.5 million. Since we began developing and




                                       9

marketing our Internet-based health care applications, services, and product
offerings in early 1999, we have funded our business primarily by borrowing
funds and from the sale of convertible preferred stock, and from our initial
public offering of stock, not from cash generated by our business. We expect to
continue to incur significant sales and marketing, research and development and
general and administrative expenses. As a result, we will experience losses and
negative cash flows for the foreseeable future. Factors which may prevent us
from achieving or maintaining profitability and cause our stock price to decline
include the demand for and acceptance of our solutions and our ability to
attract new customers.

     During 1999 and through February 10, 2000, the effective date of the
Company's initial public offering, in connection with stock options granted to
certain employees and a consultant under the stock plan, we recorded unearned
stock compensation representing the difference between the exercise price of the
options and the deemed fair value of our common stock at the date of grant. This
unearned stock compensation will be amortized to expense over the period during
which the options or common stock subject to repurchase vest, generally four
years, using an accelerated method as described in Financial Accounting
Standards Board Interpretation No. 28. Amortization of unearned stock
compensation amounted to approximately $518,000 during the three months ended
March 31, 2000. We expect to recognize amortization expense related to unearned
compensation for the aforementioned grants of approximately $1,510,000 in 2000,
$570,000 in 2001, $260,000 in 2002 and $52,000 in 2003.

     In 1999, Laidlaw Inc., the Canadian parent company of American Medical
Response, Inc. announced its intention to divest its interest in that company in
order to focus on its transportation business. American Medical Response, Inc.
is the parent company of one of our customers, American Medical Pathways, Inc
("AMP"). If such a sale is consummated, and the new owner decided to terminate
our agreement, there would likely be a material adverse impact on our future
earnings and cash flow. As of March 31, 2000, there has been no change in our
relationship with AMP and we have continued to provide services under our
agreement.

     The following table sets forth, for the periods indicated, certain items
from the Company's statements of operations as a percentage of total revenue:

COMPARISON OF THE COMPANY'S RESULTS FOR THE THREE MONTHS ENDED MARCH 31, 2000
AND 1999.

     Total revenue. Total revenue increased $1.6 million, or 117%, to $2.9
million for the three months ended March 31, 2000 from $1.3 for the three months
ended March 31, 1999. This increase reflects revenue recognized from existing
customers and an increase in average total arrangement fees during the three
months ended March 31, 2000, as compared to the same 1999 period.

     Cost of revenue. Cost of revenue includes personnel and related overhead
costs, payments to third-party consultants who assist with implementation and
support services, facilities costs and equipment depreciation. Cost




                                       10
<PAGE>   11
of revenue increased $1.9 million, or 203%, to $2.8 million for the three months
ended March 31, 2000 from $923,000 for the year earlier period. This increase
reflects the cost of additional personnel hired to support the growth in our
internet-based implementation and customer development. Also, for the three
months ended March 31, 2000, significant research and development costs were
charged to cost of revenue. This resulted from the Company entering into a
development agreement with a major customer prior to completion of the internal
development effort. We anticipate cost of revenue expenditures will increase as
we continue to expand our internet strategy.

     Sales and marketing. Sales and marketing expenses consist of personnel and
related overhead costs, including commissions, travel expenses, field sales
office expenses and advertising and promotion costs. Sales and marketing
expenses increased $955,000, or 616%, to $1.1 million during the three months
ended March 31,2000 from $155,000 for the three months ended March 31, 1999.
This increase reflects salary and benefit increases due to the growth of sales
and marketing personnel by approximately 370%, as well as the associated
increases in support areas such as facilities and telephone costs. In
conjunction with this growth, expenses were incurred to develop an in-depth
market and competitive analysis and brand development plan. Additionally, travel
and entertainment and trade show and conference expenses increased as the
marketing program was expanded and intensified.

     General and administrative. General and administrative expenses include
personnel and related overhead costs for our executive, administrative, finance
and human resources functions, as well as legal and accounting fees. General and
administrative expenses increased $1.7 million, or 1,196%, to $1.9 million for
the three months ended March 31, 2000 from $144,000 from the year earlier
period. This increase was due to the rapid growth of the Company, as well as its
transition from a private Company to a public company. Growth related expenses
were primarily due to an increase in personnel and recruiting costs in the areas
of human resources, accounting and administration. To increase the rate of
growth, outside contractors have been hired to perform certain support functions
as the permanent staff is being assembled. Professional fees increased due to
additional legal and accounting fees associated with periodic reporting
requirements of a public company. Officers and directors insurance was obtained
subsequent to becoming a public company, resulting in an increase in insurance
expense of approximately $80,000. Additionally, to settle a dispute, we revised
the exercise price of a warrant to purchase shares of common stock, and in
conjunction with the exercise of those warrants, recorded a one-time charge of
$132,000 during the first quarter of 2000.

     Research and development. Research and development expenses include
personnel and related overhead costs for product development, enhancements to
existing applications and services and quality assurance activities. Research
and development expenses increased $357,000, or 343%, to $461,000 for the three
months ended March 31, 2000 from $104,000 for the three months ended March 31,
1999. This increase reflects an increase in salaries and benefits due to a 42%
increase in departmental personnel and the use of outside contractors.

     Stock compensation expense. During the three months ended March 31, 2000,
we recorded aggregate unearned compensation of $122,000 in connection with the
grant of certain stock options. Amortization of the aggregate amount of unearned
compensation amounted to $518,000 for the three months ended March 31, 2000.

     Interest income (expense), net. Interest income (expense), net includes
interest expense on our convertible promissory notes and capital lease
obligations offset by interest income on cash and cash equivalent balances.
Interest income, net of interest expense, increased $834,000, to $698,000 for
the three months ended March 31, 2000 from a net interest expense of $136,000
for the prior year. This increase is due to the conversion of convertible
promissory notes to Series B convertible preferred stock in June 1999, the
reduction of debt and capital lease obligations during 1999 with the proceeds of
the Series B preferred stock issued for cash, as noted above, and the interest
income realized from the investment of the proceeds from our initial public
offering which occurred in February 2000.

     Income tax (benefit) expense. No provision for federal and state income
taxes has been recorded for the three months ended March 31, 2000 or 1999 as we
have incurred net operating losses for each of these periods. We believe that,
based on the history of losses and other factors, the weight of available
evidence indicates that it is




                                       11
<PAGE>   12



more likely than not that we will not be able to realize our deferred tax
assets, and thus a full valuation allowance has been recorded against such
assets as of March 31, 2000 and 1999.






                                       12
<PAGE>   13




     Net loss. Net loss increased $3.1 million to $3.2 million for the three
months ended March 31, 1999 from $151,000 for the year earlier period. This
increase is the result of increases in revenue of $1.6 million and interest
income (expense), net of $834,000, offset by an increase in total costs and
expenses of $5.4 million, as discussed above.


LIQUIDITY AND CAPITAL RESOURCES

     We have historically financed our operations through a combination of cash
flow from operations, private sales of common and convertible preferred stock,
and issuances of convertible promissory notes. At March 31,2000, our principal
sources of liquidity included $98.8 million in working capital with no long-term
outstanding debt. The Company performs ongoing evaluations of its customers'
financial condition and, generally, requires no collateral from its customers.
All such customers operate in the health care industry.

     On February 9, 2000, the SEC declared effective the Company's Registration
Statement on Form S-1. Pursuant to this Registration Statement, the Company
completed an Initial Public Offering ("IPO") of 5,750,000 shares of its common
stock (including 750,000 shares sold pursuant to the exercise of the
underwriter's over-allotment option) at an IPO offering price of $18.00 per
share (the "Offering"). Proceeds to the Company from the Offering, after
calculation of the underwriter's discount, totaled approximately $94.2 million,
net of offering costs of approximately $2.0 million. Concurrent with the closing
of the IPO, all outstanding shares of the Company's convertible preferred stock
were automatically converted into 9,108,122 shares of common stock. In addition,
upon closing of the IPO, all outstanding common stock warrants and the Series A
convertible preferred stock warrants were exercised. The Series A convertible
preferred stock issued upon the exercise of the latter warrants was
automatically converted into common stock and together with the exercise of the
common stock warrants, resulted in the issuance of 702,924 additional shares of
common stock.

     We expect to use our cash and cash equivalents, as well as the net proceeds
from this offering, for general corporate purposes, working capital and capital
expenditures to fund our operations, including to continue expanding and
enhancing our sales and marketing operations and to continue expanding our
product offerings. The amounts and timing of our actual expenditures will depend
upon numerous factors, including the status of our product development efforts,
marketing and sales activities, and the amount of cash generated by our
operations and competition. We may find it necessary or advisable to use
portions of the proceeds for other purposes. A portion of the proceeds may also
be used to acquire or invest in complementary businesses or products or to
obtain the right to use complementary technologies, although there are no
current plans, negotiations or discussions for any such transactions. Pending
use of the net proceeds for the above purposes, we intend to invest such funds
in short-term, interest-bearing, investment grade obligations.

     Net cash used in operating activities for the three months ended March 31,
2000 was $2.8 million and net cash provided by operating activities for the
three months ended March 31, 1999 was $276,000. Net cash used in operating
activities is primarily attributable to net losses and net cash provided by
operating activities is primarily attributable to an increase in certain
liability accounts.

     Net cash used in investing activities for the three months ended March 31,
2000 and 1999 was $1.1 million and $36,000, respectively. Investing activities
consist primarily of purchases of computer hardware and software, office
furniture and equipment, offset by proceeds from the sale of property and
equipment.

     Net cash provided by financing activities for the three months ended March
31, 2000 was $95.3 million and net cash used for financing activities for the
three months ended March 31, 1999 was $165,000 and consists primarily of net
proceeds from our initial public offering.

     We anticipate that the above funds will be sufficient to meet our needs as
described above for the next eighteen months. Thereafter, we may require
additional funds to support our working capital requirements or for other
purposes, and we may seek, even before such time, to raise additional funds
through public or private equity financing or from other sources. Such
additional financing may not be available at all or, if available, on terms




                                       13
<PAGE>   14


acceptable to us and that are not dilutive to our stockholders.

RECENT ACCOUNTING PRONOUNCEMENTS

     The Securities and Exchange Commission issued Staff Accounting Bulletin
(SAB) No. 101, "Revenue Recognition in Financial Statements," as amended, in
December 1999 that provides further interpretive guidance for public companies.
SAB No. 101 will be effective for the Company's second quarter of 2000.
Management anticipates that the adoption of SAB No. 101 will not have a material
impact on the Company's financial condition or results of operations and that it
will not have a significant impact on its current licensing or revenue
recognition practices.


FACTORS AFFECTING THE COMPANY'S BUSINESS, OPERATING RESULTS AND FINANCIAL
CONDITION

     In addition to other information contained in this Quarterly Report on Form
10-Q, the following risk factors should be carefully considered in evaluating
the Company and its business because such factors currently have a significant
impact, or may have a significant impact, on the Company's business, operating
results or financial condition.

     We have experienced quarterly fluctuations in our operating and financial
results due to the timing and relative size of new custom software development
projects, cancellations of projects and fluctuations in cost including
personnel, equipment and facilities costs. We expect quarterly results to
fluctuate in the future due to the timing and introduction of new applications
and services and other market factors.

     Additional risk factors that currently have a significant impact, or may
have a significant impact on the Company's business, operating results or
financial condition include, but are not limited to, those discussed in the
Company's Annual Report on Form 10-K for the year ended December 31, 1999, under
"Risk Factors" on pages 30 - 40. Unless required by law, the Company undertakes
no obligation to update publicly any forward-looking statements, whether as a
result of new information, future events, or otherwise. However, readers should
carefully review the risk factors set forth in other reports or documents the
Company files from time to time with the Securities and Exchange Commission.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     In the ordinary course of its operations, the Company is exposed to certain
market risks, primarily changes in interest rates. Uncertainties that are either
nonfinancial or nonquantifiable, such as political, economic, other regulatory,
or credit risks are not included in the following assessment of the Company's
market risks.

     Interest Rates. Investments, including cash equivalents, consist of U.S.,
state, and municipal bonds, as well as domestic corporate bonds, with maturities
of up to 18 months. All investments are classified as held-to-maturity as
defined in SFAS No. 115. "Accounting for Certain Investments in Debt and Equity
Securities," and, accordingly, are carried at amortized cost.


Part II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

     There are no material legal proceedings pending against us. We could become
involved in litigation from time to time relating to claims arising out of our
ordinary course of business.


ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

     On February 9, 2000, the SEC declared effective the Company's Registration
Statement on Form S-1. Pursuant



                                       14
<PAGE>   15


to this Registration Statement, the Company completed an Initial Public Offering
("IPO") of 5,750,000 shares of its common stock (including 750,000 shares sold
pursuant to the exercise of the underwriter's over-allotment option) at an IPO
offering price of $18.00 per share (the "Offering"). Proceeds to the Company
from the Offering, after calculation of the underwriter's discount, totaled
approximately $94.2 million, net of offering costs of approximately $2.0
million. Concurrent with the closing of the IPO, all outstanding shares of the
Company's convertible preferred stock were automatically converted into
9,108,122 shares of common stock. In addition, upon closing of the IPO, all
outstanding common stock warrants and the Series A convertible preferred stock
warrants were exercised. The Series A convertible preferred stock issued upon
the exercise of the latter warrants was automatically converted into common
stock and together with the exercise of the common stock warrants, resulted in
the issuance of 702,924 additional shares of common stock.

     We expect to use the net proceeds from this offering for general corporate
purposes, working capital and capital expenditures to fund our operations,
including to continue expanding and enhancing our sales and marketing operations
and to continue expanding our product offerings. The amounts and timing of our
actual expenditures will depend upon numerous factors, including the status of
our product development efforts, marketing and sales activities, and the amount
of cash generated by our operations and competition. We may find it necessary or
advisable to use portions of the proceeds for other purposes.

     A portion of the proceeds may also be used to acquire or invest in
complementary businesses or products or to obtain the right to use complementary
technologies, although there are no current plans, negotiations or discussions
for any such transactions. Pending use of the net proceeds for the above
purposes, we intend to invest such funds in short-term, interest-bearing,
investment grade obligations.

processing of transactions related to electronic commerce. XCare.net reserves
the right to discontinue the Services to Client if either XCare.net believes in
good faith that Client has violated the foregoing, or that Client's use of the

the remaining provisions of this Agreement shall be unimpaired and the parties
will substitute a new enforceable provision of like economic intent and effect.

receipt.

5.6 Governing Law. This Agreement, the rights and obligations of the parties
hereto, and any claims or disputes thereto, shall be governed by and construed
in accordance with the laws of the State of New York without reference to
conflict of law principles.

5.7 Mediation. Any Dispute that the Parties are unable to resolve through
informal discussions or negotiations will be submitted to non-binding mediation,
which will be held in New York, New York. The Parties will mutually determine
who the mediator will be from a list of mediators obtained from the AAA office
located in New York, New York. If the Parties are unable to agree on the
mediator, the mediator will be selected by the AAA.

5.8 Arbitration. Any Dispute that the Parties are unable to resolve through
mediation pursuant to Section 10.12 will be submitted to arbitration in
accordance with the following procedures:

         5.8.1.   Demand for Arbitration; Location. Either Party may demand
                  arbitration by giving the other Party written notice to such
                  effect, which notice will describe, in reasonable detail, the
                  facts and legal grounds forming the basis for the filing
                  Party's request for relief and will include a statement of the
                  total amount of damages claimed, if any, and any other remedy
                  sought by that Party. The arbitration will be held before one
                  neutral arbitrator in New York, New York.

         5.8.2.   Identification of Arbitrator. Within thirty (30) calendar days
                  after the other Party's receipt of such demand, the Parties
                  will mutually agree upon an arbitrator. If the parties are
                  unable to agree on the arbitrator within that time period, the
                  arbitrator will be selected by the AAA. The arbitrator will
                  have a background in, and knowledge of, the information
                  technology services. If a person with such industry experience
                  is not available, the arbitrator will be chosen from the large
                  and complex case panel or, if an appropriate person is not
                  available from such panel, the retired federal judges pool.

         5.8.3.   Conduct of Arbitration. The arbitration will be governed by
                  the Commercial Arbitration Rules of the AAA, except as
                  expressly provided in this Section 10.13. However, the
                  arbitration will be administered by an organization mutually
                  agreed to in writing by the Parties. If the Parties are unable
                  to agree upon the organization to administer the arbitration,
                  it will be administered by the AAA under its procedures for
                  large and complex cases. Pending the arbitrator's
                  determination of the merits of the Dispute, either Party may
                  apply to any court of competent jurisdiction to seek
                  injunctive or other extraordinary relief.

         5.8.4.   Scope of Discovery. Discovery will be limited to the request
                  for and production of documents, depositions and
                  interrogatories. Interrogatories will be allowed only as
                  follows: a Party may request the other Party to identify by
                  name, last known address and telephone number (i) all persons
                  having knowledge of facts relevant to the Dispute and a brief
                  description of that person's knowledge, (ii) any experts who
                  may be called as an expert witness, the subject matter about
                  which the expert is expected to testify, the mental
                  impressions and opinions held by the expert and the facts
                  known by the expert (regardless of when the factual
                  information was acquired) which relate to or


                                                                               5

                  form the basis for the mental impressions and opinions held by
                  the expert and (iii) any experts who have been used for
                  consultation, but who are not expected to be called as an
                  expert witness, if such consulting expert's opinions or
                  impressions have been reviewed by an expert witness. All
                  discovery will be guided by the Federal Rules of Civil
                  Procedure. All issues concerning discovery upon which the
                  Parties cannot agree will be submitted to the arbitrator for
                  determination.

         5.8.5.   Authority of Arbitrator. In rendering an award, the arbitrator
                  will determine the rights and obligations of the Parties
                  according to the substantive and procedural laws of the State
                  of New York. The arbitrator will not have authority to award
                  damages in excess of the amount or other than the types
                  allowed by Section 5.2, except in the case of gross negligence
                  or willful misconduct, and may not, in any event, make any
                  ruling, finding or award that does not conform to the terms
                  and conditions of this Agreement, except in the case of gross
                  negligence or willful misconduct.

         5.8.6.   Joinder of Parties. Each of Vendor and Customer agree that it
                  will use commercially reasonable efforts to join (and will
                  allow the other Party to join) any Third Party that the
                  Parties have agreed is indispensable to the arbitration. If
                  any such Third Party does not agree to be joined, the
                  arbitration will proceed nonetheless.

         5.8.7.   Award. The decision of, and award rendered by, the arbitrator
                  will be final and binding on the Parties. Upon the request of
                  a Party, the arbitrator's award will include written finding
                  of fact and conclusions of law. Judgement on the award may be
                  entered in and enforced by any court of competent
                  jurisdiction. Each Party will bear its own costs and expenses
                  (including filing fees) with respect to the arbitration,
                  including one-half of the fees and expenses of the arbitrator.

         5.8.8.   Exclusive Remedy. Other than those matters involving
                  injunctive or other extraordinary relief or any action
                  necessary to enforce the award of the arbitrator, the Parties
                  agree that the provisions of this Article 10 are a complete
                  defense to any suit, action or other proceeding instituted in
                  any court or before any administrative tribunal with respect
                  to any Dispute or the provision of the Services by Vendor.
                  Nothing in this Article 10 prevents the Parties from
                  exercising their rights to terminate this Agreement in
                  accordance with Article 8.

5.9      Jurisdiction. All disputes arising out of or relating to this Agreement
         shall be submitted to the non-exclusive jurisdiction of the state and
         federal courts encompassing New York, New York, and each party
         irrevocably consents to such personal jurisdiction and waives all
         objections thereto.

5.10 Headings. Section headings contained in this Agreement are inserted for
convenience or reference only, shall not be deemed to be a part of this
Agreement for any other purpose, and shall not in any way define or affect the
meaning, construction or scope of any of the provisions hereof.

5.11 Independent Contractors. The relationship of the parties hereunder shall be
that of independent contractors. Nothing herein shall be construed to constitute
a partnership between or joint venture of the parties, nor shall either party be
deemed the agent of the other or have the right to bind the other in any way
without the prior written consent of the other.

5.12 Execution in Counterparts. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original, and all of which,
when taken together, shall constitute one and the same instrument.

5.13 Publicity. Client understands that Internet use, and related products and
Services provided under this Agreement, may require registrations and related
administrative reports which are public in nature. In addition, Client and
XCare.net agree that either party may include its name and a description of the
provided services as a reference or in client/vendor portfolios.

deletions or other changes to a Schedule shall be mutually agreed to in writing
in advance by both parties and shall be memorialized in a revised Schedule
pursuant to the procedure set forth in Section 2.6 below for Change Orders. All
services shall be performed at Xcare.net's offices unless otherwise agreed by
the parties. In the event that services are performed at Client's location,
Client shall provide Xcare.net at no charge with all necessary facilities and
equipment, including without limitation, computer time on Client's computers and
office space, sufficient to render the services contemplated hereunder. Client
shall deliver to Xcare.net all Content selected by Client for incorporation into
any Client Web Site in digitized format in accordance with the delivery schedule
set forth in the applicable Schedule(s). In the event that Client fails to
deliver the Content in accordance with the delivery schedule, the development
schedule shall be extended by the number of days that delivery of the Content
was delayed, unless Xcare.net notifies Client that this extension will not
rectify Xcare.net's scheduling interruption resulting from Client's delay and
such delay may also result in additional charges to Client, in which case the
parties shall mutually agree upon a new delivery schedule and fees with respect
to the rendition of the Development Services.

         2.2. Acceptance of Deliverables. Within fifteen (15) days after the
delivery to Client of any deliverable pursuant to any Schedule, Client shall
provide Xcare.net with written notice of any failure of any deliverable to
materially conform to the functional specifications set forth in the applicable
Schedule. Xcare.net and Client shall review the objections, and Xcare.net will
use commercially reasonable efforts to correct any material non-conformities
with the functional specifications and provide Client with a revised deliverable
within fifteen (15) days. Client shall have deemed to have accepted the
deliverable if Xcare.net does not receive written notice of Client's objections
within said fifteen (15) day period.

         2.3. Domain Name Registration Services. If domain name registration
services are included in the Schedule, Xcare.net shall use commercially
reasonable efforts to assist Client in registering an Internet domain name
selected by Client. Client will be solely responsible for all out-of-pocket
costs and all legal clearances regarding name selection and registration.

         2.4. Maintenance Services. If Client desires to purchase maintenance

from Xcare.net for the Client Web Site, the parties shall execute the then

revised Schedule(s) shall be subject to the terms and conditions of this
Agreement. Further, Xcare and Client agree to allow reasonable, non-material
modifications to the contract if both Xcare and Client agree to such change.

responsibility under this Section 5.1 shall be to use reasonable commercial
efforts to promptly correct material errors, or at Xcare.net's option, to refund
Client's fees paid for the Xcare.net Software after deinstallation and return
thereof. All warranty claims not made in writing or not received by Xcare.net
within the Warranty Period shall be deemed waived. Xcare.net's warranty
obligations are solely for the benefit of Client, who has no authority to extend
or transfer this warranty to any other person or entity.

6. INTELLECTUAL PROPERTY INDEMNIFICATION

         6.1. Xcare.net.

               6.1.1. Indemnification. Xcare.net, at its own cost and expense,
shall defend Client and its officers and directors, against a claim that the
Xcare.net Software infringes a third-party United States copyright or trade
secret, and shall pay any settlements entered into or damages awarded against
Client, or its officers and directors, to the extent related to such claim,
provided that (i) Client notifies Xcare.net promptly in writing of the claim;
(ii) Xcare.net has the sole control of the defense and all related settlement
negotiations; and (iii) Client provides Xcare.net with all reasonably necessary
assistance, information, and authority to perform the foregoing at Xcare.net's

               6.1.2. Xcare.net shall have no liability for any claim of
infringement based on (i) use by Client of other than the current update of the
Xcare.net Software if the infringement would have been avoided by uses of the
current update; (ii) modifications, adaptations or changes to the Xcare.net
Software not made by Xcare.net; (iii) the combination or use of the materials
furnished hereunder with materials not furnished by Xcare.net if such
infringement would have been avoided by use of the Xcare.net materials alone; or
(iv) use or incorporation of Content or Modified Content. In the event the
Xcare.net Software is held to, or Xcare.net believes is likely to be held to,
infringe the intellectual property rights of a third party, Xcare.net shall have
the right at its sole option and expense to (i) substitute or modify the
Xcare.net Software






                                       6








<PAGE>   7
so that it is non-infringing and qualitatively and functionally equivalent to
the Xcare.net Software; (ii) obtain for Client a license to continue using the
Xcare.net Software; or if neither (i) nor (ii) is commercially reasonable,
Xcare.net shall have the right to terminate this Agreement immediately upon
written notice to Client, and Xcare.net shall make payment to Client of an
amount equal to the fees paid for the Xcare.net Software, pro-rated over a three
(3) year period commencing on the Effective Date. This Section 6.1 sets forth
Client's sole and exclusive remedy and Xcare.net's sole liability for
intellectual property infringement by Xcare.net.

without limitation, all text, pictures, audio, video, logos and copy contained

regulations regarding Content.

               6.2.2. Client shall indemnify and hold harmless Xcare.net, its

<PAGE>   10
the other party's name, domain name, logo, trademark or service mark in

Xcare.net's client portfolio. Xcare.net shall also have the right to display its

Site(s), and to receive credit as the developer of the Client Web Site(s),
(collectively, the "Credit"). Such Credit shall appear on the "home page" of the
Client Web Site(s) in a position that provides reasonable and appropriate
visibility to Xcare.net in light of industry standards and Client's

          10.  Confidentiality and Proprietary Rights.

                  (a)      Confidentiality. Each party acknowledges that it has
                           or may, during the course of this Agreement received
                           information relating to the other party's assets,
                           operations, clients, and past, present, and future
                           businesses, including but not limited to
                           developments, technical data, specifications,
                           designs, ideas, product plans, research and
                           development, personal information, financial
                           information, customer lists, business methods and
                           operations, and marketing programs, all of which are
                           proprietary exclusively with such other party and
                           involve trade secrets, know-how, techniques, and
                           combinations of known information of a character
                           regarded by such party as confidential (collectively,
                           "Confidential Information"). Each party acknowledges
                           that all the other party's Confidential Information
                           is material and confidential and greatly affects the
                           goodwill and the effective and successful conduct of
                           such other party and its businesses and operations,
                           and that maintaining confidentiality of the
                           Confidential Information is reasonably necessary to
                           protect the legitimate business interests of such
                           other party. Accordingly, each party hereby agrees to
                           receive all such Confidential Information in strict
                           confidence and that neither it nor any of its
                           officers, directors, representatives, employees or
                           agents (including any consultants, subcontractors or
                           advisors) shall, at any time, directly or indirectly,
                           divulge, reveal or communicate to any third party the
                           existence or the terms of this Agreement or any
                           Confidential Information to any person, firm,
                           corporation or entity whatsoever, or use, pursue or
                           exploit any Confidential Information for its own
                           benefit or for the benefit of others. Each party
                           agrees that, upon demand of the other party, it and
                           its officers, directors, representatives, employees
                           or agents (including any consultants or advisors)
                           shall immediately return to such other party all
                           tangible material pertaining to Confidential
                           Information in its possession or control. Each party
                           shall disclose and enforce in writing the
                           confidentiality provisions of this Agreement with all
                           its officers, directors, representatives, employees
                           or agents (including any consultants, subcontractors
                           or advisors).

                  (b)      Proprietary Rights. Title to the XCare.net Product
                           and all other products, trade secrets and other
                           proprietary information developed independently by
                           XCare.net, including without limitation all
                           copyrights thereto, shall remain with XCare.net at
                           all times. Title to the e-MEDx Product and all other

                           including without limitation all copyrights thereto,
                           shall remain with e-MEDx at all times. All software,
                           documentation or other products developed jointly by
                           and between XCare.net and e-MEDx, including
                           derivative works created jointly based on either the
                           XCare.net Product or the e-MEDx Product in the
                           development of the Combined Product shall be jointly
                           owned by XCare.net and e-MEDx and the parties shall
                           cooperate in and bear equally the expenses associated
                           with securing appropriate joint copyright
                           registrations and other forms of intellectual
                           property protection through engagement of mutually
                           acceptable counsel. Additionally, the parties agree
                           to cooperate and share equally the expenses of
                           conducting appropriate "right to use" or infringement
                           investigations prior to marketing the Combined
                           Product, and in the event of any claim based on the
                           Combined Product infringing a third party's
                           intellectual property rights based on the combination
                           of the XCare.net Product and the e-MEDx Product
                           rather than the XCare.net Product or the e-MEDx
                           Product not in combination, the parties shall
                           cooperate and share the expenses and any liability
                           imposed proportionately based on royalties received
                           by each party on sales of the Combined Product.

                           Each party agrees that all tangible objects
                           containing or relating to the other party's products
                           and all copies thereof are the sole and exclusive
                           property of such other party and upon termination of
                           this Agreement for any reason, each party will
                           forthwith return to the other party all of such other
                           party's products and User Documentation,

                           hereunder and shall not retain any copies for its use
                           or for any purpose except as otherwise specifically

                           obligations with End Users. Neither party shall copy

                           property. Each party will promptly during the term of
                           this Agreement and thereafter, notify the other party
                           of any actual or suspected unauthorized use or

                           as it may be modified from time to time, and, in the
                           event that either party develops new software in
                           order to create the Combined Product, such party
                           agrees to deposit the source code and associated
                           design documentation of all components of such

                           referred to as the "Deposited Material"). The parties

                           contain instructions to release the Deposited

                           not develop them in the event that such party
                           notifies the escrow agent that (i) the developing
                           party has materially breached and fails or refuses to
                           perform under this Agreement; or (ii) any bankruptcy,
                           reorganization, debt arrangement, or proceeding under
                           any bankruptcy or insolvency laws or any dissolution
                           or liquidation proceeding commenced by or against the
                           developing party and as to such case or proceeding

                           provisions of this Section, the non-breaching party
                           will not have an adequate remedy in money or damages,
                           and accordingly shall, in addition to any other
                           available legal or equitable remedies, be entitled to
                           an injunction against such breach without any
                           requirements to post bond as a condition of such
                           relief.

                           terminated in the event of a material breach. The
                           non-breaching party must provide NINETY (90) DAYS
                           written NOTIFICATION specifying such material breach,
                           if the breaching party fails to cure the breach
                           within a thirty (30) day period.

                  (c)      Automatic Termination. Either party may terminate
                           this Agreement, effective immediately upon written

                           assets of the other party are transferred to an
                           assignee for the benefit of creditors, to a receiver
                           or

                  (d)      Effect of Termination. All licenses and other rights
                           granted by each party to the other party hereunder
                           shall become null and void upon the termination of

                           agreements or understandings between the parties,
                           whether express or implied or written or oral,

                           forth herein. Neither party shall be bound by any

                           information as to the matters which are the subject

                  (j)      Force Majeure. Neither party shall be responsible for
                           any failure to perform due to unforeseen
                           circumstances or for causes beyond its control which
                           prevents such party from performing under this
                           Agreement, provided that such party provides notice
                           to the other party describing the circumstances
                           alleged to constitute force majeure. Such party shall
                           be permitted to delay its performance only for as
                           long as the circumstances constituting force majeure
                           are present.

                  (k)      Severability. This Agreement is intended to be
                           performed in accordance with and only to the extent

                           and regulations of the jurisdictions in which the
                           parties do business. If any provision of this
                           Agreement, or the application thereof to any person
                           or circumstances shall, for any reason or to any
                           extent, be invalid or unenforceable, the remainder of
                           this Agreement and the application of such provision
                           to other persons or circumstances shall not be
                           affected thereby, but rather shall be enforced to the
                           greatest extent permitted by law.

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

                  (m)      Further Assurances. The parties hereto agree to
                           execute and deliver such further instruments and do
                           such further acts and things as may be reasonably
                           necessary or required to carry out the intent and
                           purposes of this Agreement.

         13. PUBLICITY: THE PARTIES SHALL WORK TOGETHER AS MUTUALLY AGREED UPON
         TO ISSUE A PUBLICITY AND GENERAL MARKETING COMMUNICATION CONCERNING THE
         EXECUTION OF THIS AGREEMENT. NEITHER PARTY SHALL ISSUE SUCH PUBLICITY
         AND GENERAL MARKETING COMMUNICATION WITHOUT THE PRIOR WRITTEN CONSENT
         OF THE OTHER PARTY (NOT TO BE UNREASONABLY WITHHELD). NEITHER PARTY
         SHALL DISCLOSE THE TERMS OF THIS AGREEMENT TO ANY THIRD-PARTY OTHER
         THAN TO COUNSEL, AUDITORS AND FINANCIAL ADVISORS EXCEPT AS REQUIRED BY
         LAW.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement on
         the date set forth above.

Through the use of e-IDM, a provider can quickly identify the most appropriate
care guidelines for a patient with a chronic disease. The provider can then use
e-IDM to create a plan for the patient based on those guidelines. The plan
contains alerts which will notify the provider both when clinical data suggests
that a change to the plan might be required and when the time has come for some
further action -- eg, an office visit, a phone call to the patient, a test.
e-IDM allows providers to use explicit care plans to manage the care of their
patients -- but in a way that not only does not increase the amount of time that
needs to be spent attending to the patient, but actually decrease the time.

Features and Benefits:

SNAPPNET --

SNAPPNET outputs custom forms and applications with the single push of a button.
All customers do is create a one-time, in-depth profile that covers the spectrum
of professional and practice data typically asked on credentialing applications
and other related forms. The completed profile is stored in EXPERTPRACTICE.COM's
secure database, which can be accessed and reviewed or updated at any time. When
a new application or form is needed, the customer can choose the appropriate
selection from an extensive library and SNAPPNET automatically inserts the
appropriate information into the requested document.

Check the advantages SNAPPNET delivers:

      o     Allows customers to enter data once and use it unlimited times.

      o     Automatically fills out and prints applications and forms.

      o     Eliminates time-consuming processing of lengthy forms.

      o     Custom pre-entered practice data to suit virtually any credentialing
            document.

      o     Easy access to data for updates and modifications.

      o     Security through password-protected entry.

CREDENTIALSAGENT --

CREDENTIALSAGENT puts customers in control of the credentialing process and
takes away the hassle of completing and managing thousands of pieces of paper.
CREDENTIALSAGENT combines a repository for the health care professional's
credentialing documents (e.g., licenses, malpractice certificates,
educational/CME information, etc.) with a provider-centric credentialing
verification service. It also gives customers an agent who can be the
coordinator and representative to health plan and hospital administrative staff,
alleviating the time consuming process of responding to multiple requests for
credentials.

All customers do is create a profile online and then send EXPERTPRACTICE.COM the
usual credentialing source documents, that are verified in compliance with the
national accreditation organizations. Customers have online access to the file
at all times, so it's easy to stay updated on the verification process and to
update the file just once when changes need to be made.

Once primary source verification is complete, all data is stored in
EXPERTPRACTICE.COM's secure database and refreshed on a real-time basis. We
interact with payers on the customers behalf, so they never again have to
provide information in hardcopy form when they apply for HMO/PPO network
participation or to join a hospital staff. Plus, they will be eligible to
receive new patient referrals and additional revenue more quickly, as
CREDENTIALSAGENT reduces the time it takes payers to complete the credentialing
process from several months to a couple of weeks.

With CREDENTIALSAGENT, customers can:

      o     Control the credentialing process for network participation and
            hospital privileges.

      o     Have online access to files any time to see credentialing status, as
            well as view and change the list of organizations authorized to view
            their information.

      o     Provide authorization to whichever organizations they choose,
            allowing them to view the information at their convenience.

      o     Make a change to the file and have it immediately update all
            affiliated plans and hospitals.

      o     Enjoy the convenience of a single storage and update site for all
            credentialing documents, secured by password protected entry.

      o     Feel confident knowing that credentials receive in-depth
            verification conducted in accordance with standards set by NCQA,
            JCAHO and URAC.

Cut the time between application and new patient referrals from several months
to a couple of weeks (and sometimes even days), thereby increasing practice
revenue.

INFOMINERS

INFOMINERS is a data warehouse solution developed by experts with years of
experience in the managed care industry. The software is written in the language
and context of managed care resulting in data that is organized and presented in

navigational tools, designing the database, and writing the numerous programs
necessary to administer the database. Instead, INFOMINERS provides a
ready-to-install package that is fully compatible with existing information
systems and can be customized to support individual content and report
requirements. The "best of breed" navigational tools incorporated into the
solution are easy to use and totally intuitive. Information is retrieved, viewed

COMPETITIVE SITUATIONS

It is expected that from time to time, e-MEDx and XCare.net will encounter
situations in which they are, or could, compete for the same client's business.
In these situations, the companies will adhere to the policy that the first
organization into an account will be the organization that works to win the
business -- the other organization will professionally exit the opportunity, and
promote the remaining party to the client. When extenuating circumstances (like
a special connection or other reason) may improve the chances of one
organization to win an opportunity over the other, or when there is
confusion/disagreement about who was in first, these situations will be
escalated to the designated senior executives within each company, and a
decision will be made at that level.

Those currently designated for this role are:

                         For e-MEDx:         David C. Bjork
                                             EVP, Sales & Marketing

                                             SVP, Sales & Business Development

PRICING

Retail pricing for products identified within this agreement is the
responsibility of the owner/author of the software. Prices will be market-driven
and published on a quarterly basis for the Reseller. Special pricing
considerations that have not be contemplated in the published pricing (i.e.
large volume deals) will be determined on a case-by-case basis by the designated
senior executives within each company.

                                    and any schedules and/or exhibits appended

                                    Services rendered, the amount negotiated by

                                    Attachment.

                           b.       Out-of-Pocket Expenses. In the event that

                                    location, Client shall reimburse Xcare.net

                                    Xcare.net personnel rendering such Services
                                    at Client's location, so long as Xcare.net
                                    submits bona fide receipts documenting such
                                    expenses in accordance with Client's
                                    reimbursement policy.

                                    invoice for actual Services rendered at
                                    least monthly. Each invoice will set forth
                                    the Services rendered during the immediately
                                    preceding month, identified by task or
                                    project components, the number of
                                    person-hours devoted to each such task or
                                    project component, the per hour fee for each
                                    person who performed and the aggregate fee
                                    for the billing period. It is the parties
                                    intention that Client may remit payment
                                    either in cash or by issuance of Client's
                                    capital stock. If Client elects to pay
                                    Xcare.net in cash, Client must remit payment
                                    within ten(10)

                                    business days after receipt of Xcare.net's
                                    second monthly invoice for Services for
                                    which a balance is then due. If Client fails
                                    to remit payment within ten (10) business
                                    days after receipt of Xcare.net's second
                                    invoice, then, commencing on the 11th
                                    business day, Xcare.net may begin to charge
                                    interest on the balance due at a rate of one
                                    and one-half (1.5%) per month or the maximum
                                    rate permitted by law, whichever is less,
                                    until the balance due is paid. If, however,
                                    Client elects to issue capital stock as
                                    remittance for the balance due, the grace
                                    period for payment may be longer, as
                                    follows: Client must provide to Xcare.net a
                                    detailed term sheet relating to the capital
                                    stock proposed to be issued and the terms
                                    and payment by capital stock must be
                                    preapproved by Xcare.net. To allow a
                                    reasonable amount of time for Xcare.net's
                                    review and approval and a reasonable amount
                                    of time for Client's board of directors to
                                    take the required corporate action, Client
                                    may have up to ten (10) business days after
                                    receipt of Xcare.net's third monthly invoice
                                    for Services for which a balance is then due
                                    to issue its capital stock. If Client fails
                                    to issue the stock to Xcare.net within
                                    such ten day period, then Xcare.net may
                                    charge interest on the balance due. Such
                                    interest shall be calculated retroactively
                                    to the date of the first monthly invoice in
                                    the immediately preceding three month
                                    period, at a rate of one and one-half (1.5%)
                                    per month or the maximum rate permitted by
                                    law, whichever is less, until the balance
                                    due is paid.

                  4. TERM AND TERMINATION.

                           a.       Term. The term of Services for which Client
                                    contracts on each Attachment will commence
                                    on the Effective Date of that Attachment
                                    and, unless an Attachment specifies a
                                    particular term or describes a finite
                                    project for which a deadline is established,
                                    the term for such Services will extend until
                                    terminated as set forth below.

                           b.       Termination for Cause. This entire
                                    Agreement, or any particular Attachment
                                    alone, may be terminated by either party in
                                    the event of (i) any material default in, or
                                    material breach of, any of the terms and
                                    conditions of this Agreement (or any
                                    material default in, or material breach of,
                                    any of the terms and conditions of a
                                    particular Attachment, as the case may be)
                                    by the other party, which default continues
                                    in effect after the defaulting party has
                                    been provided with written notice of default
                                    and thirty (30) days to cure such default;
                                    (ii) the commencement of a voluntary case or
                                    other proceeding seeking liquidation,
                                    reorganization or other relief with respect
                                    to either party of its debts under any
                                    bankruptcy, insolvency, or other similar law
                                    now or hereafter in effect, that authorizes
                                    the reorganization or liquidation of such
                                    party or its debt or the appointment of a
                                    trustee, receiver, liquidator, custodian or
                                    other similar official of it or any
                                    substantial part of its property; (iii)
                                    either party's consent to any such relief or
                                    to the appointment of or taking possession
                                    by any such official in an involuntary case
                                    or other proceeding commenced against it; or
                                    (iv) either party's making a general
                                    assignment for the benefit of creditors; or

                                    party taking any corporate action to
                                    authorize any of the foregoing.

                           c.       Termination for Convenience. This entire
                                    Agreement, or any particular Attachment
                                    alone, may be terminated by either party
                                    upon one hundred twenty (120) days' advance
                                    written notice (or such shorter or longer
                                    period of time as may be set forth in any
                                    particular Attachment).

                           d.       Effect of Termination. If this Agreement is
                                    terminated by either party for any reason,
                                    Client shall remit payment to Xcare.net of
                                    the total undisputed fees associated with
                                    all projects and tasks completed as of the
                                    termination date, as well as all amounts due
                                    and owing for any third-party products or

                                    behalf. The foregoing shall be without
                                    limitation to the rights and remedies of
                                    either party under this Agreement

                           e.       Survival. Any section of this Agreement
                                    hereto addressing confidentiality,
                                    intellectual property rights, warranties,
                                    disclaimers, indemnification, termination
                                    and governing law shall survive any
                                    termination or expiration of this Agreement
                                    and the Attachment.

                  5. CONFIDENTIALITY

                           a.       Confidential Information. Each party
                                    acknowledges that, in connection with the
                                    performance of this Agreement, it may
                                    receive certain Confidential Information of
                                    the other party.

                           b.       Covenant. Each party hereby agrees: (i) to
                                    hold and maintain in strict confidence all
                                    Confidential Information of the other party
                                    and not to disclose it to any third party;
                                    and (ii) not to use any Confidential
                                    Information of the other party except as
                                    permitted by this Agreement or as may be
                                    necessary to perform its obligations under
                                    this Agreement. Each party will use at least
                                    the same degree of care to protect the other
                                    party's Confidential Information as it uses
                                    to protect its own Confidential Information
                                    of like importance, and in no event shall
                                    such degree of care be less than reasonable
                                    care.

                           c.       Exceptions. Notwithstanding the foregoing,
                                    the parties agree that Confidential
                                    Information will not include any information
                                    that: (i) is or becomes generally known or
                                    is or becomes part of the public domain
                                    through no fault of the other party, (ii)
                                    the disclosing party authorizes to be
                                    disclosed; (iii) is rightfully received by
                                    the receiving party from a third party
                                    without restriction on disclosure and
                                    without breach of this Agreement; or (iv) is
                                    known to the other party on the Effective
                                    Date from a source other than the party
                                    claiming that the information is
                                    Confidential Information, and not subject to
                                    a confidentiality obligation.

                           d.       Injunctive Relief. Each party acknowledges
                                    that any breach of the provisions of this
                                    section may cause irreparable harm and
                                    significant injury to an extent that may be
                                    extremely difficult to ascertain.
                                    Accordingly, each party agrees that the
                                    other party will have, in addition to any
                                    other rights or remedies available to it at
                                    law or in equity, the right to injunctive
                                    relief, without posting

                                    any bond (unless required by statute) and
                                    without showing actual damages, to enjoin
                                    any breach or violation of this section.

                  6. GENERAL PROVISIONS

                           a.       Force Majeure. In the event that either
                                    party is unable to perform any of its
                                    obligations under this Agreement or to enjoy
                                    any of its benefits because of any event
                                    beyond the control of the affected party
                                    including, but not limited to, natural
                                    disaster, acts of God, actions or decrees of
                                    governmental bodies or failure of
                                    communication lines (a "Force Majeure
                                    Event"), the party who has been so affected
                                    shall promptly give written notice to the
                                    other party and shall use its best efforts
                                    to resume performance. Upon receipt of such
                                    notice, all obligations under this Agreement
                                    shall be immediately suspended for the
                                    duration of such Force Majeure Event.

                           b.       Notice. All notices, demands, requests or
                                    other communications required or permitted
                                    under this Agreement will be deemed given
                                    (i) when delivered personally; or (ii) five
                                    (5) days after having been sent by
                                    registered or certified mail, return receipt
                                    requested, postage prepaid; or (iii) one (1)
                                    day after deposit with a commercial
                                    overnight carrier, with written verification
                                    of receipt or (iv) on the same day, if
                                    transmitted by facsimile documented by a
                                    printed transmission report. Any notice
                                    required or permitted under this Agreement
                                    shall be in writing and delivered to the
                                    address set forth below, or such other
                                    address as the other party has provided by
                                    written notice.

                           c.       Waiver. Waiver of any breach or failure to
                                    enforce any term of this Agreement shall not
                                    be deemed a waiver of any breach or right to
                                    enforce which may thereafter occur. No
                                    waiver shall be valid against any party
                                    hereto unless made in writing and signed by
                                    the party against whom enforcement of such
                                    waiver is sought and then only to the extent
                                    expressly specified therein.

                           d.       Severability. In the event any one or more
                                    of the provisions of this Agreement shall
                                    for any reason be held to be invalid,
                                    illegal or unenforceable, the remaining
                                    provisions of this Agreement shall be
                                    unimpaired and the parties will substitute a
                                    new enforceable provision of like economic
                                    intent and effect.

                           e.       Governing Law. This Agreement, the rights
                                    and obligations of the parties hereto, and
                                    any claims or disputes thereto, shall be
                                    governed by and construed in accordance with
                                    the laws of the State of Colorado without
                                    reference to conflicts of law principles.

                           f.       Assignment. Neither party shall have the
                                    right to assign this Agreement without the
                                    prior written consent of the other party;
                                    provided, that either party shall have the
                                    right to assign this Agreement to any person
                                    or entity that acquires or succeeds to all
                                    or substantially all of such party's
                                    business or assets upon written notice to
                                    the other party.

                           g.       Publicity. If the parties agree that a press
                                    release regarding this Agreement is
                                    appropriate, then, they will collaborate on
                                    a joint press release announcing the
                                    existence of this Agreement. Neither party
                                    will use the other party's name, domain
                                    name, logo, trademark or service mark in
                                    advertising or publicity without obtaining
                                    the other party's prior written consent;
                                    provided, however, that Xcare.net shall have
                                    the nonexclusive right and license to use
                                    Client's name and Client Web Site name,
                                    including the URL thereto, as a Client
                                    reference, and as part of Xcare.net's client
                                    portfolio. Xcare.net shall also have the
                                    right to display its name and logo, as well
                                    as a link to the Xcare.net site, on the
                                    Client Web Site, and to receive credit as
                                    the developer of the Client Web Site,
                                    (collectively, the "Credit"). Such Credit

                         XCARE.NET DEVELOPMENT SERVICES

The parties intend that the terms and conditions set forth in this Attachment
are read in conjunction with the terms and conditions in the Agreement to which
this Attachment is appended.

1. DEFINITIONS

All capitalized terms used in this Attachment and not defined in this Attachment
shall have the meanings ascribed to them in the Agreement.

         1.1. "Client Content" shall mean marketing collateral, data, text,
audio files, video files, graphics and other materials provided by Client
(whether owned by Client or licensed to Client by a third party) or developed
hereunder for use with the Client Web Site or product, but excluding the
Xcare.net Software.

         1.2 "Development Services" shall mean design, development, and set-up
services as necessary to design and produce the Client Web Site or products
and/or any other consulting and project management services rendered in
accordance with the specifications identified in the appropriate Schedules, if
any, attached hereto.

         1.3. "Xcare.net Software" shall mean certain computer program code used
to create seamless cross-platform information flow and process business logic to
combine data from disparate sources. If, and to the extent that, such Xcare.net
Software is used by Xcare.net in rendering Development Services, it shall be
provided in object code form only unless the parties mutually agree in writing
to delivery of source code.


2. DEVELOPMENT SERVICES

         2.1. Development Services. Xcare.net shall render Development Services
in accordance with the specifications identified in Schedule 1-A attached
hereto. Any additions, deletions or other changes to Schedule 1-A shall be
mutually agreed to in writing or orally in advance by both parties and shall be
memorialized in a revised Schedule 1-A pursuant to the procedure set forth in
Section 2.3 below for Change Orders. All services shall be performed at
Xcare.net's offices unless otherwise agreed by the parties. In the event that
services are performed at Client's location, Client shall provide Xcare.net at
no charge with all necessary facilities and equipment, including without
limitation, computer time on Client's computers and office space, sufficient to
render the Services contemplated hereunder. Client shall deliver to Xcare.net
all Client Content selected by Client for incorporation into the Client Web Site
or product in digitized format in accordance with the delivery schedule set
forth in Schedule 1-A. In the event that Client fails to deliver the Client
Content in accordance with Schedule 1-A, Xcare.net's schedule for delivery of
Development Services shall be extended by the number of days that delivery of
the Client Content was delayed, unless Xcare.net


                                       8
<PAGE>   9




notifies Client that this extension will not rectify Xcare.net's scheduling
interruption resulting from Client's delay. If Client determines that,
notwithstanding the delay of Client's deliverables, timely delivery of
Xcare.net's Development Services is critical, then such delay may also result in
additional charges to Client, in which case the parties shall mutually agree
upon a new delivery schedule and fees with respect to the expedited rendition of
the Development Services.

         2.2. Acceptance of Deliverables. Within fifteen (15) business days
after the delivery to Client of any deliverable pursuant to Schedule 1-A, Client
shall provide Xcare.net with written notice of any failure of any deliverable to
materially conform to the functional specifications set forth in Schedule 1-A.
Xcare.net and Client shall review the objections, and Xcare.net will use
commercially reasonable efforts to correct any material nonconformities with the
functional specifications and provide Client with a revised deliverable within
fifteen (15) days after such review. Client shall have deemed to have accepted
the deliverable if Xcare.net does not receive written notice of Client's
objections within the fifteen (15) day period after the original delivery.

         2.3. Change Orders. If Client desires to make changes to an existing
Schedule, the parties shall mutually agree upon an additional or revised
Schedule for each new Change Order. Each such Schedule shall be successively
numbered (e.g., 1.A, 1.B, etc.) and shall be executed by the parties. Any
revised Schedule(s) shall be subject to the terms and conditions of this
Agreement.


3. OWNERSHIP AND LICENSE RIGHTS

         3.2. License to Client. If Xcare.net designs and develops the Client
Web Site or product such that any Xcare.net Software is required to operate and

business needs. In either case, Xcare.net agrees to execute a conventional
escrow agreement pursuant to which the parties will establish an escrow account
with a recognized third party escrow agent to hold a complete and current copy
of the source code for the applicable Xcare.net Software; and, to the extent
that Xcare.net updates such Xcare.net Software from time to time, Xcare.net
agrees to promptly place each such update in the escrow account for the benefit
of Client. Client may grant a sublicense to a third party that Client engages to
host the Client Web Site; provided, that such third party agrees in writing to
be bound by the license and confidentiality restrictions set forth in this
Agreement. Client is prohibited from duplicating and/or distributing any
Xcare.net Software without the prior written consent of Xcare.net; provided,
however that Client may copy the Xcare.net Software only as needed for
reasonable ordinary backup or disaster recovery procedures. Client may use the
backup copies only if the installed copy is lost or destroyed or the hardware on
which the installed copy is installed becomes inoperable, provided that the use
of said backup copies is discontinued immediately when the original hardware
becomes operable.

         3.3. License to Xcare.net. For the period of time that Xcare.net is

1-A___. Xcare.net's warranty shall extend for a period of ninety (90) days from
the date that the final deliverables specified in Schedule 1-A are delivered to
Client ("Warranty Period"). Xcare.net's sole responsibility under this Section
shall be to use reasonable commercial efforts to promptly correct material

5. INTELLECTUAL PROPERTY INDEMNIFICATION

         5.1. Xcare.net.

                  5.1.1. Indemnification and Defense. Xcare.net, at its own cost
and expense, shall indemnify and defend Client and its officers, directors,
employees and contractors against any claim that the Xcare.net Software
infringes a third-party United States copyright or trade secret or other
intellectual property right, and shall pay any settlements entered into or
damages awarded against Client, or its officers, directors, employees and
contractors, to the extent related to such claim, provided that (i) Client
notifies Xcare.net promptly in writing of the claim; (ii) Xcare.net has the sole
control of the defense and all related settlement negotiations; and (iii) Client
provides Xcare.net with all reasonably necessary assistance, information, and
authority to perform the foregoing at Xcare.net's expense. Xcare.net agrees
that, in the event any action, proceeding or investigation, administrative,
legal or otherwise, is initiated against Xcare.net in connection with or arising
out of Xcare.net's performance under this Agreement or any attachment appended
to this Agreement, Xcare.net shall not (i) implead Client in any such action,
proceeding or investigation, (ii) initiate any proceeding or investigation or
file any separate action, administrative, legal or otherwise (including any
cross-claim or counter-claim), against Client or (iii) seek to recover from
Client any claims, judgments, costs, liabilities, damages or expenses, including
any attorneys' fees ("Losses"), or seek to obtain contribution or indemnity from
Client with respect to any such Losses, without regard to fault on the part of
any person or entity. For purposes of this paragraph the term Client includes
any parent, subsidiary or affiliate of Client, Client's insurance carrier and
the officers, directors, employees, agents and contractors of each of the
foregoing.

                  5.1.2. Limitation on Liability. In the event that Xcare.net
provides Client any Xcare.net Software in rendering Development Services to
Client, then Xcare.net shall have no liability for any claim of infringement
based on (i) use by Client of other than the current update of the Xcare.net
Software if the infringement would have been avoided by uses of the current
update; (ii) modifications, adaptations or changes to the Xcare.net Software not
made by Xcare.net; (iii) the combination or use of the materials furnished
hereunder with materials not furnished by Xcare.net if such infringement would
have been avoided by use of the Xcare.net materials alone; or (iv) use or
incorporation of Client Content or Modified Content. In the event the Xcare.net
Software is held to, or Xcare.net believes is likely to be held to, infringe the
intellectual property rights of a third party, Xcare.net shall have the right at
its sole option and expense to (i) substitute or modify the Xcare.net


                                       12
<PAGE>   13



Software so that it is non-infringing and qualitatively and functionally
equivalent to the Xcare.net Software; (ii) obtain for Client, at Xcare.net's
expense, a license to continue using the Xcare.net Software; or if neither (i)
nor (ii) is commercially reasonable, Xcare.net shall have the right to terminate
this Attachment immediately upon written notice to Client, but shall make Client
whole by reimbursing Client for reasonable expenses associated with development
by a third party of new software that is non-infringing and qualitatively and
functionally equivalent to the Xcare.net Software.

                  5.1.3 Work-Made-For-Hire; Assignment. As set forth in Section
3.1, all material on any media whatsoever, excluding specifically any Xcare.net
Software ("Material"), developed or prepared by Xcare.net for Client under this
Agreement, whether completed or in the process of creation, shall be deemed to
be "work-made-for-hire" and made in the course of the Development Services
rendered hereunder and shall belong exclusively to Client. Notwithstanding the
foregoing, in the event that any of the Material is deemed by a court of
competent jurisdiction not to be a work-made-for-hire under the U.S. copyright
laws, this Agreement shall operate an irrevocable assignment by Xcare.net to
Client of all rights of authorship to the Material arising under the U.S.
copyright laws. To that end, Xcare.net agrees to execute and deliver all
documents requested by Client in connection therewith. No rights of any kind in
the Material are reserved to Xcare.net.

                  5.1.4 Xcare.net warrants and represents:

                  Services is original to Xcare.net;

                  published, under circumstances which have caused, or may
                  cause, loss of copyright;
         C.       neither the Material, nor any portion thereof, violates any
                  patent, copyright, trade secret or other proprietary right of
                  any other party;
         D.       the Material will conform in all respects to Client's
                  specifications and other requirements;
         E.       in developing the Material, Xcare.net shall not utilize any
                  confidence, trade secrets or copyright protected information
                  or material of any other person or entity;
         F.       Xcare.net's employees have expertise in performing the
                  Services;
         G.       Xcare.net's employees shall comply with all relevant laws,
                  regulations, ordinances, and other governmental orders of all

                  Development Services; and,
         H.       in recognition of the critical nature of timely completion of
                  the Development Services, Xcare.net has, and shall maintain,
                  sufficient resources, facilities, capacity and manpower to
                  ensure that all Development Services will be performed by
                  qualified personnel in a workmanlike manner, and in conformity
                  with the highest standards of Xcare.net's industry.

         5.2. Client.

                  5.2.1. Client hereby represents and warrants to Xcare.net that
(i) Client has secured all necessary consents, permissions, clearances,
authorizations and waivers for the use of Client Content or Modified Content,

contained in all Client Content or Modified Content; (ii) the use of Client
Content as contemplated herein shall not infringe the copyright, trademark or
other intellectual property

Information of the other party, and in any event, to take precautions at least
as great as those taken to protect its own confidential information of a similar
nature. Company acknowledges that the terms of this Agreement are Confidential
Information of HealthGrades. The foregoing restrictions shall not apply to any
information that: (a) was known by the Receiving Party prior to disclosure
thereof by the other party; (b) was in or entered the public domain through no
fault of the Receiving Party; (c) is disclosed to the Receiving Party by a third
party legally entitled to make such disclosure without violation of any
obligation of confidentiality; (d) is required to be disclosed by applicable
laws or regulations (but in such event, only to the extent required to be
disclosed); or (e) is independently developed by the Receiving Party without
reference to any Confidential Information of the other party. Promptly upon
request of the other party, or in any event upon any termination or expiration
of this Agreement, each party shall return to the other all materials, in any
medium, which contain, embody, reflect or reference all or any part of any
Confidential Information of the other party. Each party acknowledges that breach
of this provision by it would result in irreparable harm to the other party, for
which money damages would be an insufficient remedy, and therefore that the
other party shall be entitled to seek injunctive relief to enforce the
provisions of this Section 8.1.

          8.2 INDEPENDENT CONTRACTORS. Company and HealthGrades are independent
contractors under this Agreement, and nothing herein shall be construed to
create a partnership, joint venture, franchise or agency relationship between
Company and HealthGrades. Neither party has any authority to enter into
agreements or make representations or warranties of any kind on behalf of the
other party.

          8.3 ASSIGNMENT. Neither party may assign this Agreement or any of its
rights or delegate any of its duties under this Agreement without the prior
written consent of the other party, not to be unreasonably withheld; except that
either party may, without the other party's consent, assign this Agreement or
any of its rights or delegate any of its duties under this Agreement: (a) to any
affiliate of such party; or (b) to any purchaser of all or substantially all of
such party's assets or stock or to any successor by way of merger, consolidation
or similar transaction. Subject to the foregoing, this Agreement will be binding
upon, enforceable by, and inure to the benefit of the parties and their
respective successors and assigns.

          8.4 CHOICE OF LAW; FORUM SELECTION. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of Colorado without
reference to its choice of law rules. Company hereby irrevocably consents to
exclusive personal jurisdiction and venue in the state and federal courts
located in Denver, Colorado with respect to any actions, claims or proceedings
arising out of or in connection with this Agreement, and agrees not to commence
or prosecute any such action, claim or proceeding other than in the
aforementioned courts.

          8.5 NONWAIVER; SEVERABILITY; SURVIVAL. No waiver of any breach of any
provision of this Agreement shall constitute a waiver of any prior, concurrent
or subsequent breach of the same or any other provisions hereof, and no waiver
shall be effective unless made in writing and signed by an authorized
representative of the waiving party. If any term, provision, covenant or
condition of this Agreement is held invalid or unenforceable for any reason, the
remainder of the provisions will continue in full force and effect as if this
Agreement had been executed with the invalid portion eliminated. The provisions
of this Agreement relating to confidentiality, representations and warranties,
indemnification obligations, governing law, limitations on licensing, and any
others which expressly survive will survive the termination or expiration of
this Agreement for any reason.

          8.6 FORCE MAJEURE. Neither party shall be deemed to be in default of
or to have breached any provision of this Agreement as a result of any delay,
failure in performance or interruption of service, resulting directly or
indirectly from acts of God, acts of civil or military authorities, civil
disturbances,



                                      -7-

accordance with this section.

          8.8 INTEGRATION. This Agreement contains the entire understanding of
the parties hereto with respect to the transactions and matters contemplated
hereby, supersedes all previous agreements or negotiations between HealthGrades

                     HealthGrades.com/XCare.net Product Plan

          Xcare.net will market customized health care ratings and directory
services as provided by HealthGrades.com ("HG Services") to the Target Markets.
As part of this agreement, HealthGrades shall require a minimum payment upon the
commencement of each Client agreement (to be determined on a case-by-case basis)
of which HealthGrades shall retain 100%. Thereafter, HealthGrades.com and
Xcare.net agree that HealthGrades.com shall receive payment for HG Services as
established in the Pricing Model set forth in Exhibit C.

Product Description:

1.   HealthGrades.com shall provide Client with HG Services that Client's
     members will be able to access from Clients web site.

2.   The HG Services shall provide Client with ratings and directory services
     customized to include only those providers and facilities specified by
     Client. (i.e., when a user accesses a Client's web site and uses the
     HealthGrades.com rating/directory services, that user will only see a list
     of providers/facilities that are part of the Client's panel of providers).

3.   Data elements required by HealthGrades.com from clients include (but are
     not limited to):

     o    Hospital code

     o    Provider UPIN

     o    Provider last name

     o    Provider first name

     o    Provider address (city, state, ZIP)

     o    Provider specialty

4.   Clients will provide timely data updates (preferably monthly in a complete
     replace format) to HealthGrades.com in a mutually agreeable format.

5.   HealthGrades.com needs to approve of each client's customization plan and
     data transfer capabilities before proceeding with implementation.

This description is for informational purposes only. HG Services specifications
shall be set forth along with terms and conditions by separate agreement entered
into between HealthGrades.com and Client. HealthGrades.com shall provide
XCare.net with a sample of such agreement.

                      EXHIBIT E -- TECHNICAL SPECIFICATIONS

                   HealthGrades.com/Xcare.net Product Overview

1.        HG Technical Staff understands that each Client may have different
          specialties within their site. Therefore, a cross reference table must
          be mutually developed between each Client and HG.

2.        HG Technical Staff understands that each Client will provide an
          electronic data file of providers that they are only interested in.
          This data transfer mechanism may vary based on the technology in place
          at each client's facility.

3.        HG Technical Staff and each Client will mutually agree on the
          processing that will take place given some different scenarios such
          as; unmatched results; multiple results; etc. within the Search
          Results pages.

4.        HG Technical Staff will develop a "model" database containing the
          necessary and optional data elements for the specialty and provider
          tables. These table will be the foundation that all Client's
          information is fed into.

5.        The Search Results Pages reside on HG Servers and have one standard,
          vanilla "look and feel". In other words, no customization will be
          provided for each Client. The Client will be able to "wrap" the
          Results Pages with their "look and feel".

6.        Conceptually, the process would be laid out as follows:


                             [ORGANIZATIONAL CHART]

These specifications are very high level and may change based on mutual consent.

RE:  1999 Estimated Operating Costs

Dear Mr. Starcevic:

Your 1999 estimate of operating cost escalations for Plaza Tower One is enclosed
with this letter. The Plaza Tower One ownership and management team are
budgeting 1999 operating costs for Plaza Tower One to be at $11.34 per rentable
square foot, based upon a total building area of 471,948 rentable square feet.

Although we continue to make every effort to keep operating costs at a minimum,
our goal of continuing to provide a Class A work environment combined with
inflationary pressures beyond our immediate control have resulted in an increase
in these costs for the coming year.

Budgeted improvements to your work environment at Plaza Tower One during 1999
will include the following:

o    Upgrades to the parking garage elevator lobbies;
o    An addition of one security guard to assist our tenants and guests at the
     front lobby from 7:00 a.m. to midnight;
o    A completion of Year 2000 upgrades; and
o    Energy savings projects to include an exit light retrofit, and floor
     temperature sensors, which are budgeted to occur in the first and second
     quarter of 1999.

Notes/Comments:

Marc,

The Certificate of Substantial Completion for USA Global Link at Plaza Tower
One follows this fax cover sheet. According to the certificate, Phase I was
completed July 4, 1998 and Phase II was completed July 29, 1998. Under the
Lease, the Lease Commencement Date is the earlier of one (1) day after
Substantial Completion of both Phase I and Phase II or July 29, 1998. Because
Phase II was not completed until July 29, that became the Lease Commencement
Date. The Lease Term was 61 months, beginning on that date and ending
August 31, 2003.

Please call me with your questions.

lease shall be amended to conform to such calculation.

square feet; provided, however, if there is a change in the aggregate rentable

the Leased Premises can be used for the Permitted Purpose. If Landlord
determines, in its sole opinion based on changes in zoning laws or other local
laws or ordinances, that the Leased Premises cannot be used for the Permitted
Purpose at any time during the Lease Term, either Landlord or Tenant shall have
the option to terminate this Lease. If Landlord fails to exercise such option,
Tenant shall have the right to use the Leased Premises for any other remaining
lawful purpose, for so long as the Leased Premises are then capable of
accommodating such uses.

of days during such month bears to the total number of days in such month. Rent
not paid by the first day of the month shall be subject to a late charge of
three percent (3%) per month of the amount due. For purposes of this paragraph
and until directed to do otherwise, Tenant shall mall all payments required to
be paid under this Lease to the following address:

                           c/o Property Colorado OBJLW One Corporation
                           P.O. Box 5037, Unit #78
                           Portland, Oregon 97208

         B. Operating Costs shall mean all expenses, costs and disbursements
made or required to be made by Landlord because of or in connection with the
maintenance, repair and operation of the Improved Area, including, but not
limited to, real estate taxes and assessments; use, sales, and any other taxes
(except income taxes) based on rents; personal property taxes on personal
property used in the operation of the Improved Area; equitable charges as may be
assessed to the Improved Area for the maintenance, repair and operation of the
common property of Greenwood Plaza South; the cost of all risk property

including Landlord's estimated fair market cost, not to exceed ISO Manual Rates
(Insurance Services Office), for any of such risks against which Landlord elects
to self insure; costs incurred by Landlord to comply with federal, state or
local laws regarding hazardous materials except when such compliance is required
due to the acts of Landlord or other tenants of the Building; utilities not

Building specifications; maintenance; repairs; janitorial service, operating
supplies, property management; Building services; snow removal; landscaping;
rubbish removal; tools and equipment used for the daily operation of the
Improved Area; air conditioning, heating and elevator repair and maintenance;
maintenance and repair of garage complex; security; property management fees;

<PAGE>   16
 with Disabilities Act" and similar related Federal, State and Local laws, rules
and regulations applicable to the Improved Area or otherwise cause a reduction
in any item of Operating Costs, in which case that part of such capital
expenditure attributable to the calendar year shall be included in the Operating
Costs. Operating Costs shall be reasonably allocated between the Tower and the
Retail Area. Also, if Landlord constructs any other buildings for lease within
the boundaries of the Improved Area; Operating Costs, exclusive of those
incurred directly for the Building hereunder and such other buildings, shall be
reasonably allocated between the Building hereunder and such other buildings.
The determination of Operating Costs and their allocation shall be in accordance
with generally accepted accounting principles applied on a consistent basis. If
the Building and other buildings located on the Improved Area are not fully
rented during all or a portion of any calendar year, Landlord may make an
appropriate adjustment of the Operating Costs for such year, employing sound
accounting and management principles, to determine the amount of Operating Costs
that would have been paid or incurred by Landlord had all such buildings been
one hundred percent (100%) rented, and the amount so determined shall be deemed
to have been the amount of Operating Costs for such year.

          Operating Costs allocated to Tenant shall not reflect any type or
degree of service or duty performed by or through Landlord for any other tenant
which is not required to be performed for Tenant under this Lease which results
in a cost in excess of the services or duties required to be provided by
Landlord under this Lease. Furthermore, Operating Costs shall not reflect the
costs of any services provided by Landlord to other tenants which are not
required to be performed for Tenant under this Lease to the extent Landlord is
reimbursed by such tenants for the costs of such services.

         C. During December of each calendar year or as soon thereafter as
practicable, Landlord shall give Tenant written notice of Landlord's estimate of
Tenant's Pro Rata Share of Operating Costs which exceed Base Operating Costs
payable hereunder for the ensuing calendar year.

          On or before the first day of each month during the ensuing calendar
year, Tenant shall pay to Landlord one twelfth (1/12) of such estimated amount,
provided that if such notice is not given in December, Tenant shall continue to
pay on the basis of the prior year's estimate until the month after such notice
is given. If at any time it appears to Landlord that Tenant's Pro Rata Share of
Operating Costs payable hereunder for the current calendar year will vary from
its estimate by more than twenty per cent (20%), Landlord may, by written notice
to Tenant, revise its estimate for such year, and subsequent payments by Tenant
for such year shall be based upon such revised estimate.

         D. Within one hundred twenty (120) days after the close of each
calendar year, or as soon thereafter as is reasonably practicable, Landlord
shall deliver to Tenant a statement of additional Rent for Operating Costs
payable hereunder for such calendar year. If such statement shows an amount
owing by Tenant that is less than the estimated payments for such calendar year



5 - PLAZA TOWER ONE LEASE
<PAGE>   17

previously made by Tenant, Landlord shall credit the excess to the next
succeeding monthly installment of Rent. If such statement shows an amount owing
by Tenant that is more than the estimated payments for such calendar year
previously made by Tenant, Tenant shall pay the deficiency to Landlord within
thirty (30) days after delivery of such statement.

         E. If, for any reason other than the default of Tenant, this Lease
shall terminate on a day other than the last day of a calendar year, the
additional Rent for Operating Costs payable by Tenant applicable to the calendar
year in which such termination shall occur shall be prorated on the basis which
the number of days from the commencement of such calendar year to and including
such date of termination bears to three hundred sixty-five (365).

         F. Landlord shall, upon Tenant's written request, deliver to Tenant a
written accounting showing how Operating Costs were calculated for the past
year. Tenant may object to the statement of Operating Costs for the past year
only if Tenant does so in writing to Landlord within ninety (90) days of
Tenant's receipt of Landlord's statement of Tenant's Pro Rata Share of Operating
Costs. In the event of a timely objection made by Tenant, Tenant and Landlord
agree to cooperate in good faith to resolve any such objection. The foregoing
notwithstanding, Tenant shall in no way be relieved of its obligation to pay
Tenant's Pro Rata Share of Operating Costs as calculated by Landlord during the
period in which it is cooperating with Landlord to resolve any objections as
provided herein.

                                  4. UTILITIES

         Landlord shall provide to the Leased Premises the following utility
services: water, sewer, electricity. Utility charges for which separate billings
are not available shall be treated as Operating Costs. If heat, light, water or
any other utility services are supplied to and metered directly to the Leased
Premises, Tenant shall pay the cost thereof, and make any required deposits
related thereto. Separate additional charges may be made to Tenant, if Tenant,
in Landlord's reasonable judgment, makes excessive utility system demands where
such services are not separately metered. Landlord does not warrant that any of
the utility services will be free from interruption caused by Unavoidable Delay,
as defined in paragraph 23 below.

         Landlord may, in its sole discretion, limit the number of telephone
circuits available to Tenant based on a pro rata share calculated by multiplying
the total number of circuits available to all tenants in the Building by
Tenant's Pro Rata Share. Landlord or its representative may, in its sole
discretion, elect to cause the telephone circuits/lines to be connected in
and/or to the Lease Premises at Tenant's sole cost and expense.

         Upon the expiration or termination of this Lease, Landlord may, in its
sole discretion, require Tenant to remove, at Tenant's expense, all telephone,
computer, data, or other such wiring associated with the Leased Premises to the
point-of-connection, without regard to whether such wiring was paid for and/or
installed by Tenant. The point-of-connection shall be determined by



6 - PLAZA TOWER ONE LEASE
<PAGE>   18

Landlord. Tenant shall repair, or reimburse Landlord for the cost of repairing,
any damage resulting from removal of such wiring.

                                   5. SERVICES

         Landlord shall maintain all parking and common areas, which maintenance
shall include lighting, gardening, cleaning, snow removal, sweeping, painting
and window cleaning; and shall provide for the Leased Premises and the Building
such other services, including, but not limited to, air-cooling, heating,
replacement of building standard lamps as needed and the interior janitorial
services listed on Exhibit "D", as are necessary to maintain them in reasonably
good order and condition. Landlord shall maintain and repair the exterior of the
Building, its structural portions and the roof. The cost of such services shall
be considered an Operating Cost. Any services provided to Tenant by Landlord
which are not provided to other Tenants in the building shall be provided at
Tenant's expense.

         Such services, except for janitorial services. shall be furnished by
Landlord during normal working hours (from 6:00 a.m. to 6:00 p.m. weekdays, and
from 7:00 a.m. to 1:00 p.m. on Saturdays, legal holidays excepted), or at such
other times as requested by Tenant, in which event, Tenant shall pay the
additional cost thereof. The level of services shall be that customarily
provided by landlords of first-class buildings in the Denver, Colorado area. For
purposes of this paragraph. "legal holidays" shall mean New Year's Day, Martin
Luther King Day, Presidents' Day, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, Christmas Day, and such other national holidays as may
hereafter be established by the United States government.

         Landlord shall not be liable in any event, nor shall Rent be abated,
because of interruption of such services. The foregoing notwithstanding, if any
such interruption of services causes the Leased Premises to be untenantable for
a period of at least five (5) consecutive business days, Rent shall be abated
proportionately.

                        6. INDEMNIFICATION AND INSURANCE

         A. Landlord shall not be liable to Tenant, and Tenant hereby waives all
claims against Landlord, its advisor, and property manager for any injury to or
death of any person or damage to any property or any other type claim arising
out of an incident (i) occurring in, on or about the Leased Premises by or from
any cause whatsoever, or (ii) occurring in, on or about the Improved Area by
reason of any act or omission or any active, passive or concurrent negligence or
fault of Tenant, except to the extent caused by the negligence or willful
misconduct of Landlord, its advisor, property manager, employees, agents or
contractors.

         B. In addition to Tenant's obligations under paragraph D below, Tenant
agrees to indemnify, protect, pay on behalf of, and hold harmless Landlord, its
advisor, and property manager, from and against any and all claims or liability
for any injury to or death of any person (including employees of Tenant and
Landlord) or damage to any property (including property



7 - PLAZA TOWER ONE LEASE
<PAGE>   19

belonging to Tenant and Landlord) whatsoever or any other claim (i) occurring
in, on or about the Leased Premises or any part thereof, from any cause
whatsoever or (ii) occurring in, on or about the Improved Area by reason of any
act or omission or any active, passive or concurrent negligence or fault of
Tenant, except to the extent caused by the negligence or willful misconduct of
Landlord, its advisor, property manager, employees, agents or contractors. The
obligations of indemnity set forth in this paragraph shall survive termination
of this Lease by expiration of the Lease Term or otherwise.

         C. Tenant shall, at its sole cost and expense, obtain and keep in force
during the Lease Term, all-risk property insurance (including theft, sprinkler
leakage, and boiler and machinery) on Tenant's improvements, fixtures,
furnishings and equipment in and upon the Leased Premises or Building in an
amount not less than one hundred percent (100%) of the full replacement cost
(without deduction for depreciation) thereof, with a maximum deductible of
$1,000. Landlord reserves the right to request Tenant to have a replacement
cost appraisal prepared not less than every three (3) years. All amounts
received from said insurance shall be applied to the payment of the cost of
repair or replacement of any Tenant's improvements, fixtures, furnishings and
equipment that were damaged or destroyed unless this Lease terminates prior to
such repair or replacement being made, in which case the portion of such amounts
representing improvements and fixtures which would have become Landlord's
property pursuant to paragraph 10 hereof shall be paid over to Landlord, and
the balance shall be retained by Tenant. Tenant shall also carry business
interruption insurance.

         D. Without in any way limiting Tenant's liability pursuant to paragraph
B above, Tenant shall, at its sole cost and expense, obtain and keep in force
during the term of this Lease (i) commercial general liability insurance (Bodily
Injury and Property Damage) on an occurrence form with a limit of liability not

premises-operations and products/completed operations hazards and with the
following supplementary coverages: (a) contractual liability to cover liability
assumed under this Lease; (b) personal injury liability with the "employee" and
"contractual" exclusions deleted; and (c) broad form property damage liability;
and (ii) umbrella excess liability insurance, in addition to and in excess of
the foregoing insurance policies, in an amount not less than Four Million and
no/100 Dollars ($4,000,000) per occurrence. Tenant shall also carry workers'
compensation in accordance with statutory limits and employer's liability
insurance. Landlord shall have the right, at any time or from time to time, to
reasonably adjust the amount of insurance required hereunder to reflect those
coverages and amounts typically carried by tenants such as Tenant in other
office buildings comparable to the Building, as industry standards change.

         E. All insurance required under this paragraph 6 and all renewals
thereof shall be issued by such responsible companies licensed or authorized to
do and doing business in the State of Colorado as may be reasonably approved by
Landlord. Each policy shall expressly provide that the policy shall not be
canceled or altered without thirty (30) days' prior written notice to Landlord.
All insurance under this paragraph shall name Landlord, Landlord's agent



8 - PLAZA TOWER ONE LEASE
<PAGE>   20

and advisor. Landlord's property manager and any mortgagee(s), all as
additional insureds, shall be primary and noncontributing with any insurance
which may be carried by Landlord, and shall expressly provide that Landlord, its
advisor, and property manager, although named as additional insureds, shall
nevertheless be entitled to recover against Tenant under the policy for any
loss, injury or damage to Landlord, its advisor, property manager, employees and
contractors, and shall contain a standard "cross liability" or "severability of
interest" clause.

         Upon the issuance thereof, each such policy or a duplicate or
certificate thereof shall be delivered to Landlord for retention by it.

         Tenant shall require any contractor who performs work on the Leased
Premises to carry general liability insurance and to name Landlord, its advisor
and its property manager as additional insureds.

                            7. WAIVER OF SUBROGATION

         Tenant waives on behalf of its insurers under all policies of fire and
theft, all rights of subrogation which any insurer might otherwise have to any
claims of Tenant against Landlord. Landlord waives on behalf of its insurers
under all policies of fire and theft, all rights of subrogation which any
insurer might otherwise have to any claims of Landlord against Tenant. Landlord
and Tenant shall each, prior to or immediately after the execution of this
Lease, procure from each of such insurers a waiver of all rights of subrogation
which the insurer might otherwise have as against the other, to the extent
required by this paragraph. This paragraph shall not be construed to require of
Landlord or Tenant any insurance coverage not otherwise required by this Lease
nor to waive any rights of recovery that either Landlord or Tenant may have
directly against the other to the extent that any loss or damage giving rise to
any such right of recovery is not actually covered by insurance.

                                   8. REPAIRS

         Except for services provided by Landlord, Tenant agrees to maintain in
a clean, orderly and sanitary condition and keep in good repair, the
non-structural interior of the Leased Premises, ordinary wear and tear excepted.
Such maintenance and repair shall be at the sole cost of Tenant and shall
include but not be limited to the maintenance and repair of floor covering,
ceilings and walls, front and rear doors, and all interior glass on the Leased
Premises. If Tenant fails to maintain or keep the Leased Premises in good repair
and such failure continues for fifteen (15) days after written notice from
Landlord, Landlord may perform any such required maintenance and repairs and the
cost thereof shall be additional Rent payable by Tenant within ten (10) days of
receipt of any invoice therefor from Landlord.

<PAGE>   21

                              9. TENANT'S PROPERTY

         Furnishings, trade fixtures, computer and telephone wiring, and
moveable equipment, if any, paid for and installed by Tenant, shall be the
property of Tenant. On expiration of this Lease, if there is then no Event of
Default, Tenant may remove any such property and shall remove any such property
if directed by Landlord. Tenant shall repair, or reimburse Landlord for the cost
of repairing, any damage resulting from removal of Tenant's property. If Tenant
fails to remove such property as required under this Lease, or in the event
Tenant abandons the Leased Premises, Tenant shall be deemed to have abandoned
all interest in any such property remaining or then in or upon the Leased
Premises and Landlord may remove the same as its own property and dispose of
such property as it desires without liability to Tenant.

                   10. IMPROVEMENTS AND ALTERATIONS BY TENANT

         Tenant may make such additional improvements or alterations to the
Leased Premises as it deems necessary or desirable, but only with Landlord's
prior written approval (which approval shall not be unreasonably withheld). Any
such improvements or alterations by Tenant shall be at Tenant's expense and
shall be done by a licensed contractor approved by Landlord in conformity with
plans and specifications approved by Landlord. If requested by Landlord. Tenant
will post a bond or other security reasonably satisfactory to Landlord to
protect Landlord against liens arising from work performed for Tenant. All work
performed shall be done in a good and workmanlike manner, in accordance with
applicable law and with materials (where not specifically described in the
specifications) of the quality and appearance comparable to those in the
Building. Prior to the commencement of any work or delivery of any materials to
the Leased Premises, Tenant shall furnish Landlord, for its approval, copies of
the following:

                  (a) plans and specifications;

                  (b) names and addresses of contractors;

                  (c) copies of contracts;

                  (d) necessary permits; and

                  (e) such other items as may be reasonably requested by
         Landlord to protect its interest in the Building in connection with the
         work.

         Landlord, by written notice to Tenant given at or prior to commencement
of any improvement, addition, or alteration to the Leased Premises described in
this paragraph 8, may require Tenant, at Tenant's sole cost and expense, to
remove all or any portion of such improvements, additions, or alterations at or
prior to the expiration or termination of this Lease, and to repair or restore
any damage caused by the installation and removal of such improvements,
additions, or alterations; provided, however, the only improvements, additions
or



10 - PLAZA TOWER ONE LEASE
<PAGE>   22

alterations which Tenant may remove shall be those specified in such notice.
Except for Tenant's furnishings, trade fixtures, computer and telephone wiring
and moveable equipment, property not specified for removal shall upon
termination or expiration of the Lease become the property of Landlord.
Notwithstanding the foregoing, in the case of any improvement, addition, or
alteration made without the prior written consent of Landlord, Landlord may
provide the notice contemplated by this paragraph at any time at or prior to the
termination or expiration of this Lease.

                                  11. CASUALTY

         If the Leased Premises or the Building are destroyed or damaged by
fire, earthquake or other casualty to the extent that the Leased Premises are
untenantable in whole or in part, then Landlord shall, except as provided below,
proceed with reasonable diligence to rebuild and restore the Leased Premises or
such part thereof as may be destroyed or damaged, and during the period of such
rebuilding and restoration, this Lease shall remain in full force and effect,
and Rent shall be abated in the same ratio as the square footage in the portion
of the Leased Premises rendered untenantable, if any, shall bear to the total
square footage in the Leased Premises. If Landlord shall reasonably determine
that such destruction or damage cannot be rebuilt and restored within
one-hundred-eighty (180) days of the occurrence, it shall so notify Tenant
within sixty (60) days after the occurrence of such damage or destruction. In
such event, either Landlord or Tenant may, within twenty (20) days after such
notice, terminate this Lease. If neither party terminates this Lease during such
twenty (20) day period, this Lease shall remain in effect and Landlord shall
diligently proceed to rebuild and restore the Leased Premises, and Rent shall
abate as set forth above. If Landlord determines that the Leased Premises can be
rebuilt and restored within one-hundred and eighty (180) days after the
occurrence but the rebuilding of the Leased Premises is not completed within
such one-hundred and eighty (180) day period (subject to the provisions of
paragraph 23.C., which shall not, in any event, extend the completion period
more than sixty (60) days), Landlord, within five (5) days of Tenant's written
demand, shall provide Tenant with Landlord's written assurance that the Leased
Premises will be rebuilt and restored with thirty (30) days after Tenant's
demand. If the Leased Premises are not rebuilt and restored within thirty (30)
days after Tenant's demand (subject to the provisions of paragraph 23.C.) or
Landlord advises Tenant that the Leased Premises will not be rebuilt and
restored within thirty (30) days, then either Landlord or Tenant may, within ten
(10) days after Landlord's advice to Tenant, terminate this Lease. Anything in
this Lease to the contrary notwithstanding, in the event the Leased Premises are
rendered untenantable due to the fault or neglect of Tenant, its agents,
employees, invitees, or licensees, there shall be no abatement of Rent.

                     12. ASSIGNMENT, LETTING AND SUBLETTING

         A. Except as permitted in subparagraph F below, Tenant, its legal
representatives and successors in interest, shall have no right to assign, let
or sublet or permit assigning, letting or subletting of this Lease, the Leased
Premises or any part thereof, respectively, without first obtaining the written
consent of Landlord, which consent shall not be unreasonably withheld,



11 - PLAZA TOWER ONE LEASE
<PAGE>   23
and any attempt to do so shall be null and void. Any consent of Landlord, unless
specifically stated therein, shall not relieve Tenant from its obligations under
this Lease, and a consent by Landlord to any one assignment or subletting shall
not constitute a consent to any other or subsequent assignment or subletting.

         B. In addition to any other reasonable basis, Landlord shall be deemed
to be reasonably withholding its consent to any such assignment, letting or
subletting, if such assignment, letting or subletting would result in the
assignment, leasing or subleasing of the Leased Premises to any party, business
or lessee:

            (1) who proposes to conduct a business therein which is not in
conformance with the provisions of paragraph 2 hereof; or

            (2) who is then a lessee of the Building if the Landlord has, or
will have during the ensuing six (6) months, suitable space for rent in the
Building; or

            (3) whose business is of a character which is not, in Landlord's
opinion, consistent with the character of the Building.

         C. In the event that Tenant proposes any assignment of this Lease or
sublease of the Leased Premises, Tenant shall notify Landlord in writing at
least thirty (30) days before the date on which such assignment or sublease is
to be effective and, as included in such notice, furnish Landlord with (a) the
name of the proposed assignee or sublessee (the "Transferee"), (b) a description
of the business of the Transferee, (c) financial statements of the Transferee
(audited if available), (d) all written agreements governing the sublease, and
(e) any other information reasonably requested by Landlord with respect to the
assignment, sublease or the Transferee. Landlord shall respond to Tenant's
request for approval or disapproval of the proposed assignment or sublease
within fourteen (14) days after Landlord receives Tenant's request and all
documents and information required in the preceding sentence. If Landlord
consents to a proposed assignment or sublease of this Lease, the appropriate
parties shall enter into an assignment or consent to sublease agreement drafted
by Landlord. Consent by Landlord to any assignment or subletting shall not
include consent to the assignment or transferring of any lease renewal options
or space option rights of the Premises, special privileges or extra services
granted to Tenant under this Lease, unless otherwise agreed to by Landlord in
writing.

         D. Tenant shall pay to Landlord fifty percent (50%) of all net profit
derived by Tenant from any assignment or subletting. For purposes of the
foregoing, "net profit" shall be deemed to be the amount of all rent payable by
such assignee or sublessee in any given year of the Lease Term in excess of the
Rent payable by Tenant under this Lease during such year less the following
verifiable costs and expenses: (i) any improvement allowance or other economic
concession paid by Tenant to the assignee/subtenant; (ii) broker's commissions
paid by Tenant with regard to the subletting; (iii) attorneys' fees incurred by
Tenant in connection with the assignment or sublease; (iv) lease takeover
payments; (v) costs of advertising the Premises for



12 - PLAZA TOWER ONE LEASE
<PAGE>   24

sublease, (vi) reasonable costs incurred by Tenant to make improvements to the
Premises for the assignee/subtenant to occupy the Premises, and (vii) all other
commercially reasonable costs of subletting incurred by Tenant. If a part of the
consideration for such assignment or subletting shall be payable other than in
cash, the payment to Landlord shall be in cash for its share of any non-cash
consideration based upon the fair market value thereof. Tenant shall and hereby
agrees that it will furnish to Landlord upon request from Landlord a complete
statement, certified by an officer or representative of Tenant with authority to
do so, setting forth in detail the computation of all net profit derived and to
be derived from such assignment or subletting, such computation to be made in
accordance with generally accepted accounting principles. Tenant agrees that
Landlord or its authorized representatives shall be given access at all
reasonable times to the books, records and papers of Tenant relating to any such
assignment or subletting, and Landlord shall have the right to make copies
thereof. The percentage of Tenant's profit due Landlord hereunder shall be paid
to Landlord within five (5) days of receipt by Tenant of all payments made from
time to time by such assignee or sublessee to Tenant.

         E. Tenant shall reimburse Landlord upon demand for all costs incurred
by Landlord, including reasonable attorney's fees and costs, to prepare and
negotiate all documents in connection with any requested sublease or
assignment.

         F. Notwithstanding anything to the contrary contained in this paragraph
12, Tenant need not obtain Landlord's prior consent to assign its interest in
this Lease or sublet all or any portion of the Leased Premises to an entity
which is controlled by, controls or is under common control with Tenant (an
"Affiliate"), provided that at the time of the proposed assignment or
subletting, Tenant's net worth is equal to or greater than its net worth as of
the date of this Lease. Tenant shall immediately notify Landlord of any such
assignment, purchase, transfer, sublease, action, or use. For purposes of this
Lease, "control" shall mean the possession, direct or indirect, of the power to
direct or cause the direction of the management and voting securities, by
contract or otherwise. Notwithstanding any such assignment or subletting or the
acceptance of rent by Landlord directly from any such assignee or sublessee,
Tenant shall remain fully liable for all obligations of Tenant hereunder,
without any obligation on the part of Landlord first to exhaust its remedies
against any such assignee or sublessee. Although Landlord's prior consent is not
required for transfers to an Affiliate, the Affiliate must expressly agree in
writing to assume all of Tenant's obligations under this Lease.

                            13. LIENS AND INSOLVENCY

         Tenant shall keep the Leased Premises, the Building and the Improved
Area free from any liens arising out of any work performed, materials furnished,
or obligations incurred by Tenant. If Tenant becomes insolvent or voluntarily
or involuntarily bankrupt, or if a receiver, trustee or other liquidating
officer is appointed for the business or property of Tenant. Landlord shall have
the right and option at any time thereafter to terminate this Lease by notice to
Tenant.



13 - PLAZA TOWER ONE LEASE
<PAGE>   25

                                14. CONDEMNATION

         If all or any part of the Leased Premises are taken under power of
eminent domain or like power, or sold under imminent threat thereof to any
public authority or private entity having such power, this Lease shall terminate
as to the part of the Leased Premises so taken or sold, effective as of the date
possession is required to be delivered to such authority or entity, so long as
the remainder of the Leased Premises may be used for Tenant's business. Rent for
the remaining Lease Term shall be reduced in the proportion that the Tenant's
Total Square Footage is reduced by the taking. 1f a partial taking or sale of
the Building or the Leased Premises (i) substantially reduces the area of the
Leased Premises resulting in a substantial inability of Tenant to use the Leased
Premises for Tenant's business purposes, or (ii) renders the Building unviable
to Landlord, Tenant, in the case of (i), or Landlord, in the case of (ii) may
terminate this Lease by notice to the other party within thirty (30) days after
the terminating party receives a written notice of the portion to be taken or
sold, such termination to be effective one-hundred-eighty (180) days thereafter,
or when the portion is taken or sold, whichever is sooner. All condemnation
awards and similar payments shall be paid and belong to Landlord, except any
amounts awarded or paid specifically for Tenant's trade fixtures and relocation
costs or any other amounts awarded specifically to Tenant, provided such awards
do not reduce Landlord's award. Nothing contained herein shall diminish Tenant's
right to deal on its own behalf with the condemning authority.

                          15. CONSTRUCTION CONDITIONS

         A. Tenant desires and Landlord has agreed to construct certain
improvements in the Leased Premises in the following manner. Landlord shall
first construct certain improvements ("Phase I Improvements") in that portion of
the Leased Premises consisting of approximately 6,474 rentable square feet
("Phase I Space"), as depicted in Exhibit "B-2" attached hereto. Landlord shall
notify Tenant of the Substantial Completion (as defined in Exhibit "C" attached
hereto) of the Phase I Improvements and Tenant shall promptly move all of its
personal property from the Phase II Space into the Phase I Space. Landlord shall
then construct certain improvements ("Phase II Improvements") in that portion
of the Leased Premises consisting of approximately 1,974 rentable square feet
("Phase II Space"), as depicted in Exhibit "B-2" attached hereto. The Phase I
Improvements and Phase II Improvements shall hereinafter be referred to
collectively as the "Leasehold Improvements" and shall be as described in the
Work Agreement attached hereto as Exhibit "C."

         B. Landlord shall bear the risk of loss to the Leasehold Improvements
in any portion of the Leased Premises until the Lease Commencement Date. Tenant
may inspect the Leasehold Improvements at reasonable times so long as such
inspections do not interfere with Landlord's construction activities and
Landlord's approval is received in advance of Tenant's inspection visit.



14 - PLAZA TOWER ONE LEASE
<PAGE>   26

         C. To the extent that this paragraph or paragraph 16 below conflicts
with the Work Agreement, the Work Agreement shall control.

         D. Landlord estimates that subject to the provisions of the Work
Agreement attached hereto as Exhibit "C", Substantial Completion of the Phase I
Improvements shall occur and the Phase I Space shall be certified and approved
for occupancy on or about July 3, 1998, and furthermore that Substantial
Completion of the Phase II Improvements shall occur and the Phase II Space shall
be certified and approved for occupancy on or about July 28, 1998; provided,
however, that if such Substantial Completion does not occur by such dates,
Landlord shall not be liable in damages to Tenant for any delay in Substantial
Completion and such delay shall not affect the Lease Commencement Date as
defined herein, except as otherwise provided in Exhibit "C" in the event of
Landlord Delay.

         E. By taking possession hereunder, Tenant shall have acknowledged that
it has examined the Leased Premises and accepts the same as being in the
condition called for by this Lease. Landlord shall use reasonable efforts to
correct minor defects, if any, shown on Tenant's "punch list" within 30 days
after Tenant takes possession, and in the event a major defect or omission
appears in the installation of the major building systems or structure, Landlord
agrees to correct any such defect or omission as soon as reasonably possible
after receiving notice thereof from Tenant.

                     16. OCCUPANCY, LEASE COMMENCEMENT DATE

         If Substantial Completion of the Leased Premises has not occurred by
July 28, 1998, and such delay continues for more than one hundred and twenty
(120) days after such date, plus any extensions permitted in the Work Agreement,
either party may terminate this Lease. Prior to occupying the Leased Premises,
Tenant shall execute and deliver to Landlord a letter in the form attached
hereto as Exhibit "E", acknowledging the Lease Commencement Date. If Tenant
fails to deliver such letter, the date of Substantial Completion of the Leased
Premises shall be deemed to be the Lease Commencement Date.

                            17. RULES AND REGULATIONS

         Tenant covenants that Tenant and its agents, employees, invitees, or
those claiming under Tenant, will at all times observe, perform and abide by all
reasonable rules and regulations promulgated by Landlord, from time to time, as
long as such rules and regulations do not conflict with, or unreasonably modify,
any provision of this Lease and such rules and regulations are uniformly applied
to all tenants of the Building. Landlord's rules and regulations in effect on
the date hereof are attached hereto as Exhibit "F".



15 - PLAZA TOWER ONE LEASE
<PAGE>   27
                                   18. PARKING

          Landlord shall provide non-exclusive parking within a seven level
structure (1-6 covered) contiguous to the Building. Within said structure,
Tenant shall lease from Landlord twenty-five (25) non-exclusive parking spaces
for use by the Tenant at the then-current monthly market rate, to be determined
by Landlord in its sole discretion. The current monthly market rate for such
non-exclusive parking spates is Fifty-five and no/100 Dollars ($55.00) per space
per month. Tenant shall pay the foregoing parking charges to Landlord or its
designee on the first day of each month of the Lease Term. All present and
future parking shall be within such parking areas and not within the street
right-of-way. There shall be no on-street parking. Tenant may not lease parking
spaces within said structure from anyone other than Landlord. Tenant may not
sublease parking spaces within said structure to anyone other than a subtenant
to whom an assignment, letting, or subletting was made pursuant to paragraph 12
hereof. The number of parking spaces allotted to Tenant under this paragraph has
been calculated based on a ratio of 3 parking spaces per 1,000 rentable square
feet of the Leased Premises. Therefore, if during the original or renewal term
of this Lease the square footage of the Leased Premises should change, the
number of parking spaces granted to Tenant may be modified accordingly.

                                   19. ACCESS

          Landlord or Landlord's employees, agents or contractors may enter the
Leased Premises at reasonable times for the purpose of inspecting, altering or
repairing the Leased Premises or other portions of the building and for the
purpose of ascertaining compliance by Tenant with the provisions of this Lease.
Landlord may also show the Leased Premises to prospective purchasers, renters or
lenders during regular business hours and upon reasonable notice during the last
twelve (12) months of the Lease Term, provided that Landlord shall not
unreasonably interfere with Tenant's business operations or with Tenant's use
and occupancy of the Leased Premises. Landlord shall repair, at Landlord's
expense, any damage to the Leased Premises resulting from the exercise of the
foregoing rights by Landlord or Landlord's employees, agents or contractors.

                                    20. SIGNS

          All signs and symbols placed on the doors or windows or elsewhere
about the Leased Premises, or upon any other part of the Building, including
building directories, shall be subject to the approval of Landlord. Tenant shall
have no right to place signs outside the Building and within the Improved Area.
Tenant shall be entitled to place signs within the interior of the Leased
Premises without having first obtained Landlord's approval, provided that such
signage is






16-  PLAZA TOWER ONE LEASE


<PAGE>   28


not visible from common areas of the Building, including, but not limited to,
elevators and common area corridors. Upon expiration of this Lease, all signs
installed by Tenant shall be removed and any damage resulting therefrom shall be
promptly repaired, or such removal and repair may be done by Landlord and the
cost thereof charged to Tenant as additional Rent hereunder. Notwithstanding
anything to the contrary in the foregoing, Tenant shall be allowed to (i) place
signage on the transom of the glass door leading into the annex from the
atrium, (ii) place its corporate name in the directory located in the main
lobby and in the directory located in the annex lobby, and (iii) mount a
building standard sign on the wall next to the main entrance of the Leased
Premises; provided, however, that the signage specified in items (i) and (ii)
shall be designed at Tenant's sole cost and expense and all of the foregoing
signage shall be installed at Tenant's sole cost and expense and shall be
subject to Landlord's prior written approval.

                              21. TENANT'S DEFAULT

         It shall be an "Event of Default" if (i) Tenant fails to pay Rent or
any other charge or payment required of Tenant hereunder when due and such
failure continues for ten (10) days after written notice thereof to Tenant by
Landlord; (ii) Tenant violates or fails to perform any of the other conditions,
covenants or agreements herein made by Tenant, and such violation or failure
continues for thirty (30) days after written notice thereof to Tenant by
Landlord or if such default cannot be cured within thirty (30) days if Tenant
commences to cure the default within the thirty (30)-day period, but fails to
proceed diligently and fully cure the default within forty-five (45) days; (iii)
Tenant makes a general assignment for the benefit of its creditors or files a
petition for bankruptcy or other reorganization, liquidation, dissolution or
similar relief; (iv) a proceeding is filed against Tenant seeking any relief
mentioned in (iii) above which is not dismissed within sixty (60) days after
filing; (v) a trustee, receiver or liquidator is appointed for Tenant or a
substantial part of its property; (vi) Tenant's interest under this Lease is
taken upon execution or by other process of law directed against Tenant or is
attached by or on behalf of any creditor of Tenant; or (vii) Tenant mortgages,
assigns (except as expressly permitted in this Lease) or otherwise encumbers
Tenant's interest under this Lease.

          If an Event of Default occurs, Landlord may: (i) without obligation to
do so and without releasing Tenant from any obligation under this Lease, make
any payment or take any action Landlord may deem necessary or desirable to cure
such Event of Default, and the cost thereof shall be reimbursed by Tenant to
Landlord within ten (10) days after demand; (ii) terminate this Lease by written
notice to Tenant as of the date such notice is given or as of any other date
specified in such notice; (iii) with or without terminating this Lease, reenter
and take possession of the Leased Premises by legal proceedings; (iv) with or
without terminating this Lease, if Tenant has vacated or abandoned the Leased
Premises, reenter and take possession of the Leased Premises, or any part
thereof, and remove the effects therein without liability for any damages
thereto and without being deemed guilty of any manner of trespass and without
prejudice to any other remedies of Landlord hereunder; and (v) exercise any
other legal remedy, including, without limitation, equitable remedies, on
account of such Event of Default. All remedies of



17-  PLAZA TOWER ONE LEASE

<PAGE>   29


Landlord under this Lease shall be cumulative, and the exercise of any of such
remedies shall not prevent the concurrent or subsequent exercise of any other
remedy.

          Should Landlord elect to reenter or take possession of the Leased
Premises pursuant to legal proceedings or otherwise, Landlord may, from time to
time, without any obligation to do so and without terminating this Lease, relet
the Leased Premises or any part thereof on behalf of Tenant for such term or
terms and at such rent or rents, and upon such other terms and conditions, as
Landlord may deem advisable in its sole discretion (including, without
limitation, giving concessions, free rent, and payment of concessions), with the
right to make alteration and repairs to the Leased Premises. No such reentry or
taking of possession of the Leased Premises by Landlord shall be construed as an
election on Landlord's part to terminate this Lease, unless a written notice of
termination is given to Tenant by Landlord, nor shall it preclude Landlord from
terminating this Lease at a later time by giving written notice to Tenant.

         If Landlord elects to take possession without terminating this Lease,
then such repossession shall not relieve Tenant of its obligations and
liabilities under this Lease, all of which shall survive such repossession. In
the event of such repossession, Tenant shall pay to Landlord, as Rent, all Rent
which would be payable hereunder if such repossession had not occurred, less the
net proceeds, if any, of any reletting of the Leased Premises, after deducting
all of Landlord's reasonable expenses incurred in connection with such
reletting, and rental concessions. Tenant shall pay such Rent to Landlord on the
days on which such Rent would have been payable hereunder if possession had not
been retaken.

         If, however, this Lease is terminated by Landlord, Landlord shall be
entitled to recover as damages from Tenant, in addition to all other damage
suffered by Landlord on account of any Event of Default, the present value of
all of the Rent which would have been due for the remainder of the Lease Term
had this Lease not been terminated, discounted at the rate of five percent
(5%), plus all of Landlord's costs of reletting the Leased Premises, including
repair, alteration, and preparation of the Leased Premises for reletting,
brokerage commissions, attorneys' fees, and rental concessions. Said amount
shall be immediately due and payable by Tenant to Landlord. Any amount due to
Landlord hereunder may be collected after termination.

                           22. PERSONAL PROPERTY LIEN

          As additional security for Tenant's performance of its obligations
under this Lease, Tenant hereby grants to Landlord a security interest in and to
all of the personal property of Tenant situate or to become situate on the
Leased Premises as security for the payment of all Rent and other sums due or to
become due under this Lease. Tenant shall execute such documents as Landlord may
reasonably require to evidence Landlord's security interest in such personal
property, including financing statements, separate security agreements and other
documentation. If Tenant is in default under this Lease, such personal property
shall not be



18-  PLAZA TOWER ONE LEASE


<PAGE>   30

removed from the Leased Premises (except to the extent such property is replaced
with an item of equal or greater value), without the prior written consent of
Landlord. It is intended by the parties hereto that this Lease and the
provisions herein contained shall have the effect of a security agreement
governing such personal property, and Landlord, upon the occurrence of an Event
of Default set forth in paragraph 21 may exercise any rights of a secured party
under the Uniform Commercial Code of the State of Colorado, including the right
to take possession of such personal property and, after proper notice to those
parties required by law to be notified, shall be authorized to sell the same for
the best price that can be obtained at public or private sale, and out of the
proceeds derived therefrom, to pay the amount due Landlord, and all costs
arising out of the execution of the provisions of this paragraph, paying the
surplus, if any, to Tenant. If such personal property, or any portion thereof,
shall be offered at a public sale, Landlord may become the purchaser thereof.
Notwithstanding the foregoing, Landlord shall subordinate its lien in Tenant's
personal property to the security interest of Tenant's supplier or institutional
financial source, provided that the subordination must be limited to a specified
transaction and specified items of the fixtures, equipment, or inventory
involved in the transaction. Furthermore, such subordination shall be on a form
supplied by Landlord.

                    23. QUIET ENJOYMENT, INABILITY TO PERFORM

          A. If, and so long as, Tenant pays Rent and keeps and performs each
and every term, covenant and condition herein contained on the part and on
behalf of Tenant to be kept and performed, Tenant shall quietly enjoy the Leased
Premises without hindrance or molestation by Landlord, subject to the terms,
covenants and conditions of this Lease and the Superior Instruments, as defined
and provided in paragraph 35 below.

          B. Landlord shall pay all taxes and assessments so as not to
jeopardize Tenant's use of the Leased Premises. The foregoing notwithstanding;
Landlord shall be entitled to contest any tax or assessment which it deems to be
improperly levied against the Improved Area or any part thereof, so long as
Tenant's use of the Leased Premises is not interfered with.

          C. Whenever a period of time is herein prescribed for action to be
taken by Landlord or Tenant (other than Tenant's obligation to pay rent),
Landlord or Tenant shall not be liable or responsible for and there shall be
excluded from the computation of any such period of time. any delays due to
strikes, riots, acts of God, shortages of labor or materials, war, government
laws, regulations or restrictions, or any other causes of any kind whatsoever
which are beyond the reasonable control of Landlord or Tenant (herein referred
to as "Unavoidable Delay").

                              24. HOLD OVER TENANCY

          If (without execution of a new lease or written extension) Tenant
shall hold over after the expiration of the Lease Term, Tenant may, at
Landlord's election, be deemed to be occupying the Leased Premises as a tenant
from month to month, which tenancy may be terminated as provided by law. During
such tenancy, Tenant agrees to pay to Landlord one hundred and fifty percent



19-  PLAZA TOWER ONE LEASE

<PAGE>   31


(150%) of (i) Tenant's Pro Rata Share of Operating Costs and (ii) the then
current Base Rent, as set forth herein, unless a different rate is agreed upon
in writing, and to be bound by all of the terms, covenants and conditions as
herein specified, so far as applicable.

                               25. ATTORNEYS' FEES

          In the event either party requires the services of any attorney in
connection with enforcing the terms of this Lease, or in the event suit is
brought for the recovery of any Rent due under this Lease, or for the breach of
any covenant or condition of this Lease, or for the restitution of the Leased
Premises to Landlord and/or eviction of Tenant during the Lease Term, or after
the expiration thereof, the party prevailing in any such legal action shall be
entitled to an award for all legal costs and expenses, including, but not
limited to, a reasonable sum for attorneys' fees, whether incurred at trial, on
appeal or otherwise.

                              26. AMENDMENT, WAIVER

          This Lease constitutes the entire agreement between the parties and
supersedes all prior agreements or understandings between the parties with
respect to the subject matter hereof. No prior agreement or understanding shall
be effective. This Lease shall not be amended or modified except in writing by
both parties. No covenant or term of this Lease shall be waived except with the
express written consent of the waiving party whose forbearance or indulgence in
any regard shall not constitute a waiver of such covenant or term. Failure to
exercise any right in one or more instances shall not be construed as a waiver
of the right to strict performance or as an amendment to this Lease.

                                   27. NOTICES

          All notices required by this Lease shall be in writing, sealed in an
envelope and delivered by nationally recognized overnight courier, in person, or

prepaid to the address specified below:

                           28. BINDING EFFECT, GENDER

          Subject to the provisions in paragraph 12, this Lease shall be binding
upon and inure to the benefit of the parties and their successors and assigns.
It is understood and agreed that the terms "Landlord" and "Tenant" and verbs and
pronouns in the singular number are uniformly used throughout this Lease
regardless of gender, number or fact of incorporation of the parties hereto.

                           29. ADDENDA AND ATTACHMENTS

          The typewritten addenda, exhibits or supplemental provisions, if any,
attached or added hereto, are made a part of this Lease by reference and the
terms thereof shall control over any inconsistent provisions in the paragraphs
of this Lease.

                           30. LIMITATION OF LIABILITY

          The obligations of Landlord under this Lease do not constitute
personal obligations of the individual partners, directors, officers, or
shareholders of Landlord, and Tenant shall look solely to the real estate that
is the subject of this Lease and to no other assets of the Landlord for
satisfaction of any liability in respect of this Lease and will not seek
recourse against the individual partners, directors, officers or shareholders of
Landlord or any of their personal assets for such satisfaction or for any
deficiency judgment should Tenant be unable to satisfy any liability owed to it,
unless recourse against such individuals is expressly permitted under applicable
laws. The obligations of Tenant under this Lease do not constitute personal
obligations of the individual partners, directors, officers, or shareholders of
Tenant, and Landlord will not seek recourse against the individual partners,
directors, officers or shareholders of



21-  PLAZA TOWER ONE LEASE


<PAGE>   33


Tenant or any of their personal assets for such satisfaction or for any
deficiency judgment should Landlord be unable to satisfy any liability owed to
it, unless recourse against such individuals is expressly permitted under
applicable laws.

                         31. LANDLORD'S RESERVED RIGHTS

          Without notice and without liability to Tenant, Landlord shall have
the right to:

         (1) Change (i) the name of the Building, and (ii) the Street address of
the Building if required to do so by an appropriate authority;

         (2) Install and maintain reasonable signs on the exterior of the
Building;

         (3) Make reasonable and uniform rules and regulations as, in the
judgment of landlord, may from time to time be needed for the safety of the
tenants, and the care and cleanliness of the Building and the preservation of
good order therein. Tenant shall be notified in writing when each such rule and
regulation is promulgated;

          (4) Grant utility easements or other easements to such parties, or
replat, subdivide or make such other changes in the legal status of the land
underlying the Improved Area, as Landlord deems necessary, provided such grant
or changes do not substantially or materially interfere with Tenant's use of the
Leased Premises as intended under this Lease; and

         (5) Sell the Building and assign this Lease to the purchaser (and upon
such assignment be released from all of its obligations under this Lease which
accrue after such assignment). Tenant agrees to attorn to such purchaser, or any
other successor or assign of Landlord through foreclosure or deed in lieu of
foreclosure or otherwise and to recognize such person as Landlord under this
Lease, provided that such successors execute an agreement in form and substance
similar to the Attornment and Nondisturbance Agreement attached hereto as
Exhibit "G", as provided more fully in paragraph 35 below.

                            32. ESTOPPEL CERTIFICATE

          Within ten (10) days after request therefor by Landlord, its agents,
successors or assigns, Tenant shall deliver, in recordable form, a certificate
to any proposed mortgagee or purchaser, or to Landlord, together with a true and
correct copy of this Lease, certifying, if applicable (i) this Lease is in full
force and effect, without modification, (ii) the amount, if any, of prepaid Rent
and security deposit paid by Tenant to Landlord, (iii) that Landlord, as of the
date of the certificate, has performed all of its obligations due to be
performed under this Lease and that there are no defenses, counterclaims,
deductions or offsets outstanding, or other excuses for Tenant's performance
under this Lease, or stating those claimed by Tenant, and (iv) any other fact
reasonably requested by Landlord or such proposed mortgagee or purchaser, which
does not modify or conflict with Tenant's rights under this Lease. Tenant's
failure to deliver said



22-  PLAZA TOWER ONE LEASE

<PAGE>   34

statement in time shall be conclusive upon Tenant: (a) that this Lease is in
full force and effect, without modification except as may be represented by
Landlord, (b) that there are no uncured defaults in Landlord's performance and
Tenant has no right of offset, counterclaim defenses or deduction against Rent
or Landlord hereunder; and (c) that no more than one month's Rent has been paid
in advance. The foregoing certifications by Tenant shall be set forth on an
estoppel certificate in substantially the same form as the one attached hereto
as Exhibit "H."

                           33. ACCORD AND SATISFACTION

          No receipt and retention by Landlord of any payment tendered by Tenant
in connection with this Lease will give rise to, or support, or constitute an
accord and satisfaction, notwithstanding any accompanying statement, instruction
or other assertion to the contrary (whether by notation on a check or in a
transmittal letter or otherwise), unless Landlord expressly agrees to an accord
and satisfaction in a separate writing duly executed by the appropriate
persons. Landlord may receive and retain, absolutely and for itself, any and
all payments so tendered, notwithstanding any accompanying instructions by
Tenant to the contrary. Landlord will be entitled to treat any such payments as
being received on account of any item or items or Rent, or other sums due from
Tenant hereunder in connection herewith in such amounts and in such order as
Landlord may determine at its sole option.

                                34. SEVERABILITY

          The parties intend this Lease to be legally valid and enforceable in
accordance with all of its terms to the fullest extent permitted by law. If any
term hereof shall be finally held to be invalid or unenforceable, the parties
agree that such term shall be stricken from this Lease, the same as if it never
had been contained herein. Such invalidity or unenforceability shall not extend
to or otherwise affect any other term of this Lease, and the unaffected terms
hereof shall remain in full force and effect to the fullest extent permitted by
law, the same as if such stricken term never had been contained herein.

                                35. SUBORDINATION

          The rights of Tenant hereunder are, and shall be, at the election of
any mortgagee, subject and subordinate to the lien of any deeds of trust,
mortgages, the encumbrance of any leasehold financing, or the lien resulting
from any other method of financing or refinancing, now or hereafter in force
against the Improved Area or the Building, and to all advances made, or
hereafter to be made upon the security thereof (herein referred to as the
"Superior Instruments"). The foregoing notwithstanding, for any liens or
Superior Instruments filed of record after the execution of this Lease, the
rights of Tenant under this Lease shall not be subject or subordinated to such
liens or Superior Instruments unless the holders thereof execute an agreement in
form and substance similar to the Attornment and Nondisturbance Agreement
attached hereto as Exhibit "G". If requested, Tenant agrees to execute whatever
reasonable documentation may be required to further effectuate the provisions of
this paragraph.



23-  PLAZA TOWER ONE LEASE

<PAGE>   35


          Tenant agrees to attorn to any purchaser of the Building, or any other
successor or assign of Landlord through foreclosure or deed in lieu of
foreclosure, in return for and upon delivery to Tenant by such purchaser or
mortgagee, as the case may be, of an agreement substantially in the form of the
Attornment and Nondisturbance Agreement.

                                    36. TIME

          Time is of the essence hereof.

                               37. APPLICABLE LAW

          This Lease shall be construed according to the local laws of the State
of Colorado, without regard to the principles of conflicts of law, and venue
shall be in Arapahoe County, Colorado.

                          38. BROKER'S INDEMNIFICATION

          As part of the consideration for the granting of this Lease, Tenant
represents and warrants to Landlord that no broker or agent negotiated or was
instrumental in the negotiation or consummation of this Lease except Tenant's
Broker of Record, and Tenant agrees to indemnify Landlord against any loss,
expense, cost or liability incurred by Landlord as a result of any claims by
Tenant's Broker of Record and any other broker or finder claiming through
Tenant. Landlord represents and warrants to Tenant that no broker or agent
negotiated or was instrumental in the negotiation or consummation of this Lease
except Tenant's Broker of Record and Landlord agrees to indemnify Tenant against
any loss, expense, cost or liability incurred by Tenant as a result of any
claims by any other broker or finder claiming through Landlord. Notwithstanding
the foregoing indemnification by Tenant, Landlord shall pay Tenant's Broker of
Record the sum of Three and no/100 Dollars ($3.00) per rentable square foot of
the Leased Premises equal to Twenty Five Thousand Three Hundred Forty-Four and
no/100 Dollars ($25,344.00) as a commission for this transaction. One-half
of this sum shall be paid upon the date this Lease is fully executed by the
parties hereto; the remaining one-half shall be paid upon the Lease Commencement
Date for the entire Leased Premises.

                              39. SECURITY DEPOSIT

          The Tenant has deposited with Landlord, simultaneously with the
execution of this Lease, the sum of Forty Thousand One Hundred Twenty-Eight and
no/100 Dollars ($40,128.00) as security for the Rent payable hereunder, for the
return of the Leased Premises in good order and condition, and for the
performance of each and every one of the terms, covenants and conditions herein
stipulated. Said sum shall not be applicable by the Tenant to the payment of
Rent or any other charges for which it may become liable under this lease and
such deposit shall in no way relieve Tenant from the faithful and punctual
performance of all covenants and conditions hereby imposed upon it. Landlord
agrees that at the termination of this Lease, or at the termination of



24-  PLAZA TOWER ONE LEASE

<PAGE>   36

any extension hereof, and provided that the Tenant has complied in all respects
with the terms, covenants and conditions herein, the deposit shall be returned
to Tenant thirty (30) days after the Leased Premises have been vacated in good
order and condition. In the event of a sale or leasing of the Building, Landlord
shall have the right to transfer the security deposit to its vendee and Landlord
shall thereupon be released by Tenant from all liability for the return of the
security deposit. In such event, Tenant agrees to look solely to the new
landlord for the return of said deposit. The provisions hereof shall apply to
every transfer or assignment made of the security deposit to a new landlord. The
Security Deposit shall be invested by Landlord in a Certificate of Deposit (the
"Certificate") at a bank of Landlord's choice. The Certificate will be held in
Landlord's name and will be invested for an initial term of six (6) months and
shall automatically renew, in the amount of principal plus interest for a like
term, except that the final renewal shall be for a period which results in the
Certificate maturing on the expiration date of the Lease Term. If at the end of
the Lease Term Tenant is not in default, the principal and interest remaining on
the Certificate shall be returned to Tenant.

                            40. CONFLICTS OF INTEREST

          Conflicts of interest relating to this Lease are strictly prohibited.
Except as otherwise expressly provided herein, neither Tenant nor any director,
employee or agent of Tenant, shall give to or receive from any director,
employee or agent of Landlord any gift, entertainment or other favor of
significant value, or any commission, fee or rebate. Likewise, neither Tenant
nor any director, employee or agent of Tenant shall enter into any business
relationship with any director, employee or agent of Landlord or of any
affiliate of Landlord), unless such person is acting for and on behalf of
Landlord, without prior written notification thereof to Landlord. Any
representative(s) authorized by Landlord may audit any and all records of Tenant
for the sole purpose of determining whether there has been compliance with this
paragraph.

                           41. TENANT REPRESENTATIONS

          If Tenant is a legal entity, Tenant hereby represents and warrants to
Landlord that (i) such entity is duly organized and validly existing under the
laws of the State of its formation and is qualified to do business in, and is in
good standing under, the laws of the State of Colorado, to the extent such
qualification is necessary for Tenant to conduct its business in the State of
Colorado; and (ii) this Lease and all documents executed or to be executed by
Tenant in connection herewith and which are to be delivered to Landlord will be
duly authorized, executed, and delivered and will be legal, valid, and binding
obligations of Tenant, and do not violate any provisions of any agreement or
currently existing judicial order to which Tenant is a party or to which it is
subject. Further, if requested by Landlord, either prior to or after Landlord's
execution of this Lease, Tenant shall provide Landlord with certified evidence
(i.e. certificate of authority) of the foregoing.

<PAGE>   37

                           42. ENVIRONMENTAL COVENANTS

          A. GENERAL PROHIBITION; INDEMNITY. Tenant shall not cause or permit
any explosives, flammable substances, radioactive materials, asbestos in any
form, paint containing lead, materials containing urea formaldehyde,
polychlorinated biphenyls, or any other hazardous, toxic, or dangerous
substances, wastes, or materials, whether having such characteristics in fact or
defined as such under federal, state, or local laws or regulations and any
amendments thereto (all such materials and substances being hereinafter referred
to as "Hazardous Materials"), to be produced, brought upon, used, stored,
treated, released, or disposed of on, in, or about the Leased Premises, provided
that Tenant may store and use toner, cleaning fluids, and similar office
materials if such storage and usage is (i) permitted by applicable law and (ii)
accomplished in strict compliance with such law. Tenant shall indemnify, defend,
and hold Landlord harmless from and against any and all actions, costs, claims,
damages (including without limitation, attorneys', consultants', and experts'
fees, court costs, and amount paid in settlement of any claims or actions),
fines, forfeitures, or other civil, administrative, or criminal penalties,
injunctive or other relief (whether or not based upon personal injury; property
damage, or contamination of, or adverse effects upon, the environment, water
tables, or natural resources), liabilities, or losses arising from a breach of
this prohibition by Tenant, its affiliates, agents, employees, contractors,
subtenants, assignees, or invitees.

          B. NOTICE. Tenant immediately shall notify Landlord in writing of: (i)
any spill, release, discharge, or disposal of any Hazardous Materials upon, in,
or about the Leased Premises; (ii) any enforcement, cleanup, removal, or other
governmental or regulatory action instituted, contemplated, or threatened (if
Tenant has notice thereof) pursuant to any laws respecting Hazardous Materials;
(iii) any claim made or threatened by any person against Tenant or the Leased
Premises relating to damage, contribution, cost recovery, compensation, loss, or
injury resulting from or claimed to result from any Hazardous Materials; and
(iv) any reports made to any governmental agency or entity arising out of or in
connection with any Hazardous Materials upon, in, or about or removed from the
Leased Premises. Tenant also shall supply to Landlord as promptly as possible,
and in any event within five (5) business days after Tenant first receives or
sends the same, copies of all claim, reports, complaints, notices, warnings, or
asserted violations relating in any way to the Leased Premises, or Tenant's use
or occupancy thereof.

          C. ACTION BY TENANT. In the event that Hazardous Materials are
discovered upon, in, or about the Leased Premises which have been brought upon
the Leased Premises by Tenant, its agents, employees, contractors or other
representatives, and any governmental agency or entity having jurisdiction over
the Property requires the removal of such Hazardous Materials, Tenant shall be
responsible for removing such Hazardous Materials. Notwithstanding the
foregoing, Tenant shall not take any remedial action upon, in, or about the
Leased Premises without first notifying Landlord of Tenant's intention to do so
and affording Landlord the opportunity to protect Landlord's interest with
respect thereto.



26-  PLAZA TOWER ONE LEASE

<PAGE>   38



         D. SURVIVAL. The respective rights and obligations of Landlord and
Tenant under this paragraph 42 shall survive the expiration or earlier
termination of this Lease.

         E. LANDLORD'S REPRESENTATION AS TO HAZARDOUS MATERIALS. Landlord hereby
represents and warrants to Tenant that as of the date of this Lease, Landlord
has not received any notices from any governmental authority that would put
Landlord on notice of any existing violations within the Building of any
hazardous materials laws.

                               43. RENEWAL OPTION

         A. Tenant shall have the option to renew the Lease Term for one (1)
additional five (5)-year period by notifying Landlord in writing of Tenant's
election to exercise its option at least nine (9) months but no earlier than
twelve (12) months prior to the expiration of the original term of this Lease.
Tenant may exercise such option provided Tenant is not in material default in
the performance of any of the terms or covenants of this Lease as of the time of
such exercise nor at the time the renewal period is to commence and that Tenant
has satisfied all of its conditions under this Lease. The Leased Premises shall
be leased by Tenant during the renewal term in their "as-is" condition. All
terms and conditions of this Lease shall apply during the renewal term,
provided, however, that the Base Rent and parking charges payable during such
renewal period shall be the Fair Market Rental Value (as hereinafter defined)
and shall be determined as set forth below.

          B. Fair Market Rental Value (hereinafter referred to as "FMRV") as
used in this Lease shall be the rent calculated at rates for similar space in
the Building and in comparable Class A+, high-rise buildings with comparable
finishes and amenities offered by the Building and for parking garage spaces in
similar totally enclosed parking garages located within the Denver Tech
Center/Greenwood Plaza Market Area in which the Building is located, as of the
date of Landlord's declaration to be provided to Tenant in accordance with the
following sentence. Landlord shall declare the FMRV for each year of the renewal
period, which may include annual increases, in writing to Tenant within thirty
(30) days of the date Landlord receives Tenant's notice to renew. Tenant shall
have fifteen (15) days from the date of Landlord's declaration in which to
notify Landlord that it accepts Landlord's declaration of the FMRV and wishes to
renew the Lease Term. Failing such timely notice, Tenant shall be deemed to have
waived its right to renew under this paragraph 43.

                             44. CANCELLATION OPTION

                  Tenant shall have a one-time right to terminate this Lease
effective as of the last day of the 37th month after this Lease commences with
respect to the Phase I Space (as set forth in paragraph 1.F. hereof) (the
"Termination Date"), subject to the following terms and conditions: (1) Tenant
shall give Landlord written notice of its desire to exercise the foregoing
termination right at least six (6) months prior to the Termination Date; and (2)
on or before the Termination Date, Tenant shall pay Landlord a termination fee
equal to One Hundred Fifty



27-  PLAZA TOWER ONE LEASE

<PAGE>   39

Thousand Four Hundred Fifty-Nine and no/100 Dollars ($150,459.00) (the
"Termination Fee"). Tenant and Landlord acknowledge and agree that payment to
Landlord of the Termination Fee is a reasonable forecast of the actual damages
which will be suffered by Landlord in the event Tenant exercises its termination
right set forth in this paragraph 44, which actual damages are otherwise
difficult or impossible to ascertain, and therefore such amount constitutes
liquidated damages and not a penalty.

                              45. EXPANSION OPTION

                  (A) Subject to the terms and conditions contained herein,
Tenant shall have an Expansion Option in regard to the 2,383 rentable square
feet of space adjacent to the Leased Premises which is currently occupied by the
Building Management Office (the "Expansion Space"), as depicted on Exhibit "B-3"
attached hereto.

                  (B) If at any time prior to July 31, 1998, Tenant desires to
lease the Expansion Space from Landlord, Tenant shall notify Landlord in writing
of such desire. Within sixty (60) days of Tenant's notice, if Landlord shall
determine, in its sole and absolute discretion, that there are suitable
alternative premises for the Building Management Office within the Building,
Landlord shall provide Tenant with written notice (the "Expansion Notice") that
the Expansion Space is available for leasing. Tenant shall thereupon have the
right to lease the Expansion Space in accordance with the terms set forth below,
provided that in order to exercise such right, Tenant must provide Landlord with
written notice of its intent to exercise such right within ten (10) business
days following the Expansion Notice. Should Tenant indicate that it is not
prepared to lease the Expansion Space, whether by notice to Landlord or by
failing to respond to the Expansion Notice within the ten (10)-business day
period, then Tenant shall be deemed to have waived its Expansion Option for the
Expansion Space.

                  (C) If Tenant exercises its Expansion Option, the effective
date of Tenant's leasing of the Expansion Space (the "Expansion Space Effective
Date") shall be the earlier to occur of (i) two (2) months after the Expansion
Notice, (ii) the date Tenant occupies and operates its business from the
Expansion Space, (iii) substantial completion of any tenant improvements to be
constructed within the Expansion Space, or (iv) October 1, 1998. Provided Tenant
is not in default under this Lease at the time such right is exercised or at the
time the term for the Expansion Space is to commence, Tenant shall have the
right to lease the Expansion Space upon the same terms, covenants, and
conditions set forth in this Lease, except as follows:

                           (i) Base Rent. On the Expansion Space Effective Date,
          the Base Rent due under this Lease shall be increased by an amount
          equal to Nineteen and 50/100 Dollars ($19.50) multiplied by the
          rentable square feet of the Expansion Space.

                           (ii) Operating Costs. On the Expansion Space
          Effective Date, the percentage for Tenant's Pro Rata Share shall be
          increased by a percentage determined by multiplying 100 times the
          result of dividing the square footage of the Expansion Space by



28-  PLAZA TOWER ONE LEASE

<PAGE>   40


          the Total Square Footage of the Tower. The Base Year for the Expansion
          Space shall be the calendar year ending December 31, 1998.

                           (iii) Tenant Improvement Allowance. Landlord shall
          contribute the sum of Ten and no/100 Dollars ($10.00) per rentable
          square foot of the Expansion Space as an improvement allowance toward
          the cost of planning, design and construction of any improvements
          within the Expansion Space. Notwithstanding the foregoing, any portion
          of the allowance provided for in the preceding sentence that is not
          applied toward the costs of any tenant improvements in the Expansion
          Space shall be applied to the relocation costs incurred by Landlord to
          relocate the Building Management Office.

                  (D) Except as specifically provided otherwise in the
Expansion Notice, the Expansion Space shall be leased by Tenant in "as-is"
condition. The rights of Tenant under this paragraph 45 shall not be severed
from this Lease or separately sold, assigned, or otherwise transferred, and
shall terminate at the expiration of the original term of this Lease.

                           46. RIGHT OF FIRST REFUSAL

                  (A) Subject to the terms and conditions contained herein,
after the expiration of Tenant's expansion option set forth in paragraph 45
above, Tenant shall have a continuing Right of First Refusal in regard to the
Expansion Space (which shall be referred to herein as the "First Refusal
Space").

                  (B) If at any time after August 1, 1998, during the original
five (5)-year Lease Term (but not during any renewal term), Landlord has reached
a preliminary agreement with a bona fide prospective tenant ("Prospective
Tenant") as to the essential terms of a proposal for leasing the First Refusal
Space, which Landlord intends shall serve as the basis for negotiating a lease
with the Prospective Tenant (such preliminary agreement to be referred to herein
as a "Proposal"), Landlord shall first provide Tenant with a notice ("Landlord's
Notice") which informs Tenant of the Proposal and sets forth the Base Rent,
options to expand or terminate, and the amount of any tenant improvement
allowance offered to the Prospective Tenant. Within five (5) business days
following the date of Landlord's Notice, Tenant shall have the right to lease
the First Refusal Space upon the terms set forth in Landlord's Notice (except as
otherwise provided in subparagraph (C) below), and subject to the provisions set
forth below in this paragraph 46, by providing Landlord with written notice of
its intent to exercise such right. Should Tenant indicate that it is not
prepared to lease the First Refusal Space, whether by written notice to Landlord
or by failing to respond to Landlord's Notice within the said five (5)-business
day period, then Tenant shall be deemed to have waived its Right of First
Refusal and Landlord shall be free to lease such space to the Prospective Tenant
upon substantially the same terms as set forth in the Proposal.

                  (C) In the event that Tenant exercises its Right of First
Refusal, Landlord and Tenant shall enter into an amendment to this Lease adding
the First Refusal Space to the Leased



29-  PLAZA TOWER ONE LEASE

<PAGE>   41

Premises, subject to all of the terms and conditions set forth in Landlord's
Notice, except that (i) the term for the First Refusal Space shall expire
coterminously with the expiration of the Lease Term (as may be extended by
Tenant's exercise of its renewal option set forth in paragraph 43 above) for the
Leased Premises as set forth herein, and (ii) the tenant improvement allowance
set forth in Landlord's Notice, if any, shall be prorated based upon the time
remaining in the Lease Term.

                  (D) Except as specifically provided otherwise in Landlord's
Notice, the First Refusal Space shall be leased by Tenant in "as-is" condition,
and all other improvements in the First Refusal Space shall be Tenant's
responsibility at Tenant's cost, and shall be made in accordance with paragraph
10 of this Lease.

                  (E) The rights of Tenant under this paragraph 46 are personal
to Tenant and shall not be severed from this Lease or separately sold, assigned,
or otherwise transferred.

                  (F) The rights of Tenant hereunder are subject to the rights
of other tenants with respect to the First Refusal Space pursuant to leases in
existence as of the date of this Lease, and any renewals thereof.

         (c)      Tenant shall assume the existing improvements in the Leased
                  Premises in their "AS IS" condition, subject to the provisions
                  of the Lease and this Agreement.

3.       SCHEDULE OF CRITICAL DATES

         (a)      Landlord acknowledges that Tenant has submitted a satisfactory
                  Preliminary Pricing Plan to Landlord prior to the execution
                  of this Agreement. Tenant acknowledges that Landlord has
                  submitted the Construction Drawings to Tenant prior to the
                  execution of this Agreement.

         (b)      On or about the Construction Drawings Sign-Off Date, Tenant
                  responded to Landlord with minor comments to the Construction
                  Drawings. Upon execution of the Lease, Landlord shall submit
                  revised Construction Drawings to Tenant which incorporate
                  Tenant's comments and Tenant shall sign-off on such drawings
                  within five (5) days after it receives the same from Landlord.

         (c)      Upon receipt of Tenant's written request and/or authorization
                  to make any change to the Construction Drawings or to the
                  Leasehold Improvements after the Construction Drawings Sign-
                  Off Date, which change affects contract price and/or delays
                  completion of the Phase I Improvements beyond July 3, 1998, or
                  delays completion of the Phase II Improvements beyond July 28,
                  1998, Landlord shall within four (4) business days either (A)
                  provide Tenant with Landlord's reasonable good faith estimate
                  of the increase or decrease in the number of days and revised
                  cost (if any) required to complete the Leasehold Improvements
                  occasioned by such change, or (B) inform Tenant of the number
                  of days it will take to make such a determination, in which
                  case if Tenant still desires to request such change(s),
                  Landlord shall use due diligence to provide Tenant with the
                  information in (A). The actual delay beyond July 3, 1998, or
                  July 28, 1998 as applicable, which any such change causes,
                  whether more or less than estimated, shall constitute Tenant
                  Delay. Any effect of such a change on cost which would cause
                  an increase in contract price will have no effect on the
                  amount of Improvement Allowance hereunder. Tenant agrees that
                  Landlord will not stop any construction in progress while
                  Landlord is evaluating or calculating the time required to
                  implement a change unless requested by Tenant or unless in
                  Landlord's or in General Contractor's reasonable judgment
                  construction should be stopped. Any such change order shall be
                  subject to Landlord's approval. After Landlord has approved
                  the change and provided the information described above,
                  Tenant shall then advise Landlord in writing of the acceptance
                  or rejection of the change order. The number of days from the
                  date Tenant requests a construction stop to the day
                  construction is resumed shall be Tenant Delay.

         (d)      In the event a change to the Construction Drawings after the
                  Construction Drawings Sign-Off Date is determined to be
                  required as a result of any unforeseen


4- EXHIBIT "C"


<PAGE>   55

                  condition within the existing Leased Premises, such a change
                  shall be treated as a Landlord change. Landlord will provide
                  written notice to Tenant as to the effect of such change on
                  design, cost and delay in completing the Leasehold
                  Improvements. Any delay occasioned by such a change shall be a
                  Landlord Delay and will offset accumulated days of Tenant
                  Delay (if any). Any effect of such a change on cost which
                  would cause an increase in contract price will have no effect
                  on the amount of Improvement Allowance hereunder.

         (e)      Landlord's Representative shall be the sole point of contact
                  with the General Contractor for both Landlord and Tenant
                  during construction of the Leasehold Improvements and until
                  the items on the punch list are completed or settled.
                  Landlord's Representative shall at all times have access to

                  Improvements. On the basis of his on-site observations,
                  Landlord's Representative will keep the Tenant and Landlord
                  informed of the progress of the construction of the Leasehold
                  Improvements. Landlord's Representative will not have control
                  or charge of and will not be responsible for construction
                  means, methods, techniques, sequences or procedures, or for
                  safety precautions and programs in connection with the
                  construction of the Leasehold Improvements, and he will not be
                  responsible for the General Contractor's failure to carry out
                  the construction in accordance with the Construction Drawings.
                  Landlord's Representative and Tenant will review, approve,
                  approve as noted or disapprove within two (2) business days of
                  the receipt of same, the General Contractor's submittal such
                  as Shop Drawings, Product Data and Samples, but only for
                  conformance with the design concept of the Leasehold
                  Improvements and with the information given in the
                  Construction Drawings.

         (f)      Any responses required within a certain time period under this
                  Exhibit "C" shall be in writing and shall be due by 4:00 p.m.
                  on the date specified therefor. Any such response received by
                  either party after 4:00 p.m. on any day shall be deemed to be
                  received on the next day.

         (g)      Prior to Phase I Substantial Completion, Tenant shall not have
                  access to the Phase I Space, unless previously authorized by
                  Landlord. Likewise, prior to Phase II Substantial Completion,
                  Tenant shall not have access to the Phase II Space, unless
                  previously authorized by Landlord.

                  complete as defined in Sections 5(a) and 1(p) hereof.
                  Landlord's architect will then prepare a Certificate of
                  Substantial Completion, which shall establish the date of
                  Substantial Completion, and shall have the punch list items
                  agreed to by Tenant and Landlord listed therein. The
                  inspection, compilation of the punch list and issuance of the
                  certificate of Substantial Completion shall be conducted
                  within two (2) business days after Landlord's notification.
                  Warranties required by this Work Agreement shall commence on
                  the date of Substantial Completion of the Leasehold
                  Improvements. The certificate of Substantial Completion shall
                  be submitted to the Tenant, the Landlord and the General
                  Contractor for their written acceptance of the
                  responsibilities assigned to them in such certificate. Tenant
                  shall have three (3) business days from receipt of said
                  certificate to approve and return same to Landlord. Tenant
                  shall not take possession of the Leased Premises until Tenant
                  has accepted the certificate of Substantial Completion.
                  Landlord shall use all reasonable efforts to complete the
                  items on the punch list within thirty (30) days of receipt
                  from Tenant.

         (d)      Notwithstanding the above, possession of the Leased Premises
                  by Tenant shall constitute a waiver of all claims by the
                  Tenant except those arising from (1) latent defects, (2)
                  failure of the Leasehold Improvements to comply with the
                  Construction Drawings, which failure could not reasonably have
                  been discovered upon the date the certificate of Substantial
                  Completion was issued, and (3) Landlord's failure to complete
                  in due course the incomplete items, if any, described in the
                  certificate of Substantial Completion (including the punch
                  list items). Landlord shall be responsible for (1) and (2)
                  only for a period of one year from and after the certificate
                  of Substantial Completion is issued. Landlord shall exercise
                  due diligence in completing any item in (3) of this Section
                  5(e) and shall use its good faith efforts to minimize any
                  disturbance to Tenant's operations in the Leased Premises.
                  Additionally, Landlord shall provide Tenant with any equipment
                  warranties obtained in connection with the purchase of
                  equipment which is incorporated into Tenant's Leasehold
                  Improvements. THE FOREGOING CONSTITUTES LANDLORD'S ONLY
                  WARRANTY. ALL IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO
                  THOSE OF MERCHANTABILITY, HABITABILITY, SUITABILITY AND
                  FITNESS FOR A PARTICULAR PURPOSE, ARE EXPRESSLY NEGATED AND
                  WAIVED.

         (e)      Any entry upon the Leased Premises by Tenant or its employees,
                  agents, guests, invitees, or contractors during the
                  performance of or in connection with this Work Agreement shall
                  be subject to Tenant's release, waiver and indemnification of

                              RULES AND REGULATIONS


1.       The sidewalks, entrances, halls, corridors, elevators and stairways of
         the Building shall not be obstructed or used as a waiting or lounging
         place by Tenant, or its agents, servants, employees, invitees,
         licensees, and visitors.

2.       Landlord reserves the right to refuse admittance to the Building at any
         time other than between the hours of 6:00 a.m. and 6:00 p.m. weekdays,
         or 7:00 a.m. to 1:00 p.m. on Saturdays, to any person not producing
         either a key to the Leased Premises or a pass issued by Landlord. In
         case of invasion, riot, public excitement or other commotion, Landlord
         also reserves the right to prevent access to the Building during the
         continuance of same. Landlord shall in no case be liable for damages
         for the admission or exclusion of any person to or from the Building.

3.       Landlord will furnish each Tenant with two keys to each door lock in
         the Leased Premises, and Landlord may make a reasonable charge for any
         additional keys requested by Tenant. No Tenant shall have any keys made
         for the Leased Premises; nor shall any Tenant alter any lock, or
         install new or additional locks or bolts, on any door without the prior
         written approval of Landlord. If a lock alteration or installation is
         made, the new lock must accept the master key for the Building. Each
         Tenant, upon the expiration or termination of its tenancy, shall
         deliver to Landlord all keys in such Tenant's possession for all locks
         and bolts in the Building.

4.       In order that the Building may be kept in a state of cleanliness, each
         Tenant shall, during the term of its Lease, permit Landlord's employees
         (or Landlord's agent's employees) to take care of and clean the Leased
         Premises, and Tenant shall not employ any person(s) other than
         Landlord's employees (or Landlord's agent's employees) for such
         purpose. No tenant shall cause any unnecessary labor by reason of such
         Tenant's carelessness or indifference in the preservation of good order
         and cleanliness of the Leased Premises. Tenant will ensure that before
         leaving the Leased Premises each day:

               (a)      the doors are securely locked; and

               (b)      all water faucets and other utilities are shut off (so
                        as to prevent waste or damage).

         If Tenant must dispose of crates, boxes, etc., which will not fit into
         office waste paper baskets, it will be the responsibility of Tenant to
         dispose of same by removing them from the building or by placing them
         in designated waste collection receptacles at the delivery dock. In no
         event shall Tenant place such items for disposal in the public hallways
         or other common areas of the Building or Improved Area.

         conditions that any personal property, equipment, trade fixtures,
         merchandise and other similar items shall be delivered to or removed
         from the Building. NO steel safe or other heavy or bulky object shall
         be delivered to or removed from the Building except by experienced safe
         men, movers, or riggers approved in writing by Landlord. All damage
         done to the Building by the delivery or removal of such items, or by
         reason of their presence in the Building, shall be paid by Tenant to
         Landlord, immediately upon demand therefor. For the delivery or receipt
         of merchandise, only hand-trucks equipped with rubber tires shall be
         used by Tenant, jobbers or others.

6.       The walls, partitions, skylights, windows, doors, and transoms that
         reflect or admit light into passageways or into any other part of the
         Building shall not be covered or obstructed nor have signs or
         advertisements posted on them by any Tenant.

7.       The toilet rooms, toilets, urinals, wash bowls and water apparatus
         shall not be used for any purpose other than for those for which they
         were constructed or installed, and no sweepings, rubbish, chemicals, or
         other unsuitable substances shall be thrown or placed therein. The
         expense of any breakage, stoppage or damage resulting from violations
         of this rule by Tenant or by Tenant's agents, servants, employees,
         invitees, licensees, or visitors, shall be borne by Tenant.

8.       No sign, name, placard, advertisement, or notice visible from the
         exterior of any Leased Premises shall be inscribed, painted or affixed
         by any Tenant on any window or other part of the Building or Improved
         Area without the prior written approval of Landlord. A directory
         containing the names of all tenants of the Building shall be provided
         by landlord at an appropriate place on the first floor of the Building.

9.       No electronic signaling, telegraphic, or telephonic instruments or
         devices, or other wires, instruments or devices, shall be installed in
         connection with any Leased Premises without the prior written approval
         of Landlord, which approval shall not be unreasonably withheld. Such
         installations, and the boring or cutting of wires, shall be made at the
         sole cost and expense of Tenant and under the control and direction of
         Landlord. Landlord retains, in all cases, the right to require:

                  (a)      the installation and use of such electrical
                           protecting devices that prevent the transmission of

                           Building;

                  (b)      the changing of wires and of their installation and
                           arrangement underground or otherwise as Landlord may
                           direct; and

                  (c)      compliance on the part of all using or seeking access
                           to such wires with such rules as Landlord may
                           establish relating thereto. All such wires used

10. Tenant, its agents, servants, and employees shall not:

                  (a)      go upon the roof of the Building;

                  (b)      use any additional method not approved in writing by

         THIS AGREEMENT, made as of ______________ between________________
hereinafter referred to as "Interest Holder" and USA Global Link, Inc.,
hereinafter referred to as "Tenant".

                             W I T N E S S E T H:

         THAT, WHEREAS, PROPERTY COLORADO OBJLW ONE CORPORATION, an Oregon

         WHEREAS, Interest Holder is the holder of a lien or other interest in
the form of a _______________________ and recorded at ______________________ and
any amendments, supplements or extensions thereto, hereinafter referred to as
the "Encumbrance"; and

         WHEREAS, the encumbered premises under the foregoing Encumbrance are
the same premises as, or include the Leased Premises set forth in, the legal
description above;

         NOW, THEREFORE, in consideration of the mutual covenants hereinafter
contained, the parties hereto agree as follows:

         1.       Tenant agrees that in the event of any foreclosure or the
                  exercising of any other rights under the Encumbrance, whereby
                  Interest Holder shall cause Landlord to be ousted from
                  possession or assert any right of ownership inconsistent with
                  Tenant's right under the Lease, at any time and from time to
                  time after commencement of the term of the Lease and prior to
                  the expiration, cancellation or other termination thereof, for
                  any reason, Tenant shall be bound to Interest Holder, the
                  purchaser at a foreclosure sale, any receiver appointed under
                  the Encumbrance, assignment of rents, or court order, or any
                  assignee or successor in interest (all of which are
                  hereinafter referred to as "Transferee") under all of the
                  terms, covenants, and conditions of the Lease during the
                  remaining term thereof, including any extensions or renewals
                  which may be effected in accordance with any option in the
                  Lease, with the same force and effect as if Transferee were
                  Landlord under the Lease, and Tenant does hereby attorn to
                  Transferee as its Landlord.




1- EXHIBIT "G"


<PAGE>   67

         2.       The parties hereto do hereby covenant and agree that the Lease
                  and any modifications and amendments thereto subsequently
                  approved by Interest Holder, and all rights, options, liens or
                  other charges created thereby, are, and shall continue to be,
                  subject and subordinate in all respects to the Encumbrance and
                  the lien created thereby, to any advance made thereunder, to
                  any consolidations, extensions, modifications, or renewals
                  thereof, and to any other mortgage on the Leased Premises held
                  by Interest Holder.

         3.       So long as no default exists and no event has occurred which
                  would entitle Landlord to terminate the Lease, Interest Holder
                  agrees that in the event of any foreclosure or the exercising
                  of any other rights under said Encumbrance whereby any such
                  Transferee shall oust Landlord of possession or assert any
                  right of ownership which would, in the absence of this
                  Agreement, be inconsistent with Tenant's rights under the
                  Lease and prior to the expiration or termination thereof, the
                  Lease shall, in accordance with its terms, remain in full
                  force and effect as a direct Lease between Transferee and
                  Tenant and the possession of Tenant under the Lease shall not
                  be disturbed by any such event. The Transferee shall be
                  entitled to all of the rights and benefits and subject to all
                  of the obligations of the immediately prior landlord under the
                  Lease. If successive rights should be asserted by any or
                  several Transferees separately or in any combination, Tenant
                  shall have the same rights to continue the Lease in effect in
                  each such instance.

         4.       In order to effect the provisions of the preceding paragraphs,
                  Interest Holder does hereby grant and demise to Tenant the
                  Leased Premises for a term of years to commence upon the

                  Such term of years shall be upon the terms and conditions of
                  the Lease as though the Lease were between Transferee and
                  Tenant.

         5.       The provisions of the preceding paragraphs are to be effective
                  and self operating without the execution of any further
                  instruments upon Transferee's succeeding to the interest of
                  Landlord under the Lease.

         6.       This Agreement shall inure to the benefit of and be binding
                  upon Tenant, Interest Holder, Transferee, their successors and
                  assigns.

                  covenants and conditions hereof shall apply from and after
                  said date.

                  pertain to said Lease now or as hereafter amended or extended.

         9.       Neither Interest Holder nor Transferee shall in any way or to
                  any extent (i) be obligated or liable to Tenant for any prior
                  act, omission or default on the part of Landlord under the
                  Lease, or (ii) be obligated or liable to Tenant for any
                  security deposit or other sums deposited with Landlord not

                  (iii) be bound by any previous prepayment of rent for a period
                  greater than one month, unless such modification, amendment
                  or prepayment shall have been expressly authorized in writing
                  by Interest Holder, and Tenant shall have no right to set off
                  assets or counterclaim against Interest Holder or the
                  Transferee for any of the acts or omissions of Landlord
                  referred to in (i), (ii), or (iii) above.

         10.      In the event of any act or omission by Landlord under the
                  Lease which would give Tenant the right to terminate the Lease
                  or claim a partial or total eviction, Tenant shall not
                  exercise any such right until (i) it has given notice thereof
                  to Interest Holder, and (ii) Interest Holder, following the
                  giving of such notice, shall have failed to commence or pursue
                  action to remedy such act or omission in the manner set forth
                  in the Lease.

Property Damage) on an occurrence form with a limit of liability not less than
One Million and no/100 Dollars ($1,000,000) per occurrence including
premises-operations and products/completed operations hazards and with the
following supplementary coverages: (a) contractual liability to cover liability
assumed under this Lease; (b) personal injury liability with the "employee" and
"contractual" exclusions deleted; and (c) broad form property damage liability;
and (ii) umbrella excess liability insurance, in addition to and in excess of
the foregoing insurance policies, in an amount not less than Three Million and
no/100 Dollars ($3,000,000) per occurrence; and

                  (2) Worker's compensation insurance as required by law.

                  Each liability insurance policy described above shall name
Licensor, Licensor's agent and advisor, Licensor's property manager, and
expressly including any trustees, directors, officers, employees, or agents of
any such entities, all as additional insureds.

         F. SECURITY DEPOSIT. Upon execution of this Agreement, Licensee shall
pay Licensor the sum of Four Thousand Five Hundred Dollars ($4,500.00). Such sum
shall be held by Licensor without interest as security for the performance by
Licensee of Licensee's covenants and obligations under this Agreement, it being
expressly understood that such deposit is not an advance payment of rental or a
measure of Licensor's damages in case of default by Licensee. Said deposit shall
be held by Licensor without payment of interest, as security for the faithful
performance by Licensee of all of the terms, covenants, and conditions of this
Agreement by said Licensee to be kept and performed during the term hereof. In
the event of the failure of Licensee to keep and perform any of the terms,
covenants, and conditions of this Agreement to be kept and performed by
Licensee, then the Licensor at its option may appropriate and apply the security
deposit, or so much thereof as may be necessary, to compensate the Licensor for
loss or damage sustained or suffered by Licensor due to such breach on the part
of Licensee. Should Licensee comply with all of the terms, covenants, and
conditions of this Agreement, the security deposit shall be returned in full to
Licensee within forty-five (45) days of Licensee vacating the Licensed Space;
provided, however, that Licensor shall be entitled to deduct from the security
deposit an amount sufficient to cover the cost of any required clean up of the
Licensed Space (beyond ordinary wear and tear), any unpaid costs of design and
construction of improvements to the Licensed Space undertaken by Licensor
pursuant to the terms of the letter agreement between the parties dated January
29, 1998 and any License Fee owed but not paid by Licensee.

         G. TAXES, FEES, AND UTILITIES. Any and all taxes, fees, and
assessments, including but not limited to license fees, fees for permits,
profits, sales or use taxes,

the assets, business, or capital of Licensee or Licensee's income therefrom, by
duly constituted government authority, shall be borne and paid for by Licensee.

         H.  ASSIGNMENT. It is expressly agreed that Licensee shall have no
right to assign, franchise or sublet its rights nor delegate its duties under
this Agreement. Any violation of this provision shall automatically terminate
this Agreement.

         I. NOTICES. Notices or demands required to be given or served by either

7 - LICENSE AGREEMENT

<PAGE>   1
                            FIRST ADDENDUM TO LEASE

     THIS FIRST ADDENDUM TO LEASE (this "Addendum") is made by and between
Foster Enterprises ("Lessor"), and Xcare.net, Inc. ("Lessee"), to be a part of
that certain Lease of even date herewith between Lessor and Lessee (the
"Lease") concerning approximately 6,356 square feet of space, located at 100
Winchester Boulevard, Santa Clara, California (the "Project"), Suite 250 (the
"Premises"). All terms with initial capital letters used herein as defined
terms shall have the meanings ascribed to them in the Lease unless specifically
defined herein. The numbers of the paragraphs of this Addendum correspond to
those of the Lease form. In the event of any inconsistency between this
Addendum and the Lease, the terms of this Addendum shall prevail. Lessor and
Lessee agree that, notwithstanding anything to the contrary in the Lease, the
Lease is hereby modified and supplemented as set forth below.

     3.   Term. The Lease shall commence on the later of March 1, 2000 or the
date by which all of the following have occurred: (a) Lessor has substantially
completed the Lessee Improvements in accordance with the Lease and this
Addendum; (b) Lessor has delivered possession of the Premises to Lessee; and
(c) Lessor has obtained all approvals and permits from the appropriate
governmental authorities required for the legal occupancy of the Premises for
the permitted use. If the Commencement Date has not occurred for any reason
whatsoever on or before April 1, 2000, then, in addition to Lessee's other
rights or remedies, Lessee may terminate the Lease by written notice to Lessor,
whereupon any monies previously paid by Lessee to Lessor shall be reimbursed to
Lessee, or, at Lessee's election, the date Lessee is otherwise obliged to
commence payment of rent shall be delayed by one day for each day that the
Commencement Date is delayed beyond such date. Lessor shall deliver possession
of the Premises to Lessee in good, vacant, broom clean condition, with all
building systems in good working order and in compliance with all laws.
Lessee's acceptance of the Premises shall not be deemed a waiver of Lessee's
right to have defects in the Premises repaired at no cost to Lessee. Lessee
shall give notice to Lessor whenever any such defect becomes reasonably
apparent, and Lessor shall repair such defect as soon as practicable.

     Lessor represents and warrants to Lessee that, as of the Commencement
Date, the Premises is in compliance with municipal, state and federal statutes,
rules, regulations, ordinances, requirements and orders, now in force or which
may hereafter be in force pertaining to conditions existing prior to Lessee's
lease commencement, including without limitation, all applicable statutes,
rules, regulations, ordinances, requirements or orders requiring installation
of fire sprinkler systems, seismic reinforcement and related alterations,
removal of asbestos, and compliance with ADA, fire/safety and Title 24
requirements. Lessor warranties all building systems for the first thirty (30)
days of the term.

     6.   Operating Expenses. Lessee shall have no obligation to pay the cost
of any Real Property Taxes or Operating Expenses of a type not also included in
the 2000 actual Real Property Taxes or the 2000 actual Operating Expenses. If
the 2000 actual Real Property Taxes or the 2000 actual Operating Expenses are
not based on a 95% leased Project, then such amounts shall be increased to
reflect a 95% leased Project.

          a.   Operating Expenses. "Operating Expenses" shall not include and
Lessee shall in no event have any obligation to perform or to pay directly, or
to reimburse Lessor for, all or any portion of the following repairs,
maintenance, improvements, replacements, premiums, claims, losses, fees,
charges, costs and expenses (collectively, "Costs"): (a) Costs occasioned by
the act, omission or violation of any law by Lessor, any other occupant of the
Project, or their respective agents, employees or contractors; (b) Costs
occasioned by fire, acts of God, or other casualties or by the exercise of the
power of eminent domain; (c) Costs to correct any construction defect in the
Premises or the Project or to comply with any covenant, condition, restriction,
underwriter's requirement or law applicable to the Premises of the Project on
the Lease Commencement Date; (d) Costs of any renovation, improvement, painting
or redecorating of any portion of the Project not made available for Lessee's
use; (e) Costs incurred in connection with negotiations or disputes with any
other occupant of the Project and Costs arising from the violation by Lessor
or any other occupant of
<PAGE>   2
the Project of the terms and conditions of any lease or other agreement; (f)
insurance Costs for coverage not customarily paid by Lessees of similar
projects in the vicinity of the Premises, increases in insurance Costs caused
by the activities of another occupant of the Project, insurance deductibles,
and co-insurance payments; (g) Costs incurred in connection with the presence
of any Hazardous Material, except to the extent caused by the release or
emission of the Hazardous Material in question by Lessee; (h) expense reserves;
(i) Costs of structural repairs to the Building; and (j) Costs which could
properly be capitalized under generally accepted accounting principles, except
to the extent amortized over the useful life of the capital item in question.

          b.   Real Property Taxes. "Real Property Taxes" shall not include and
Lessee shall not be required to pay any portion of any tax or assessment
expense or any increase therein (a) levied on Lessor's rental income, unless
such tax or assessment is imposed in lieu of real property taxes; (b) in excess
of the amount which would be payable if such tax or assessment expense were
paid in installments over the longest permitted term; (c) imposed on land and
improvements other than the Project; or (d) resulting from a change of
ownership or transfer of any or all of the Project or the improvement of any of
the Project for the sole use of other occupants.

          c.   Audit Rights. Lessee may audit the books, records and supporting
documents of Lessor to the extent necessary to determine the accuracy of
Lessor's statement of Operating Expenses under Section 6 of the Lease and any
subsequent statement of Operating Expenses. Such audit, if any, will occur
within one hundred eighty (180) days after Lessee receives such statement.
Lessee shall bear the cost of such audit, unless such audit discloses that
Lessor has overstated the total cost by more than three percent (3%) of the
actual amount of such costs, and in which event Lessor shall pay the cost of
Lessee's audit. Lessor shall promptly refund any overcharges to Lessee.

     8.(a)  Compliance. Lessee shall not be required to comply with or cause
the Premises to comply with any laws, rules or regulations requiring the
construction of alterations unless such compliance is necessitated solely due
to Lessee's particular use of the Premises.

     8.(c)  Hazardous Materials. To the best knowledge of Lessor, (a) no
Hazardous Material is present on the Project or the soil, surface water or
groundwater thereof, (b) no underground storage tanks are present on the
Project, and (c) no action, proceeding or claim is pending or threatened
regarding the Project concerning any Hazardous Material or pursuant to any
environmental law. Under no circumstance shall Lessee be liable for, and Lessor
shall indemnify, defend, protect and hold harmless Lessee, its agents,
contractors, stockholders, directors, successors, representatives, and assigns
from and against, all losses, costs, claims, liabilities and damages (including
attorneys' and consultants' fees) of every type and nature, directly or
indirectly arising out of or in connection with any Hazardous Material present
at any time on or about the Project, or the soil, air, improvements,
groundwater or surface water thereof, or the violation of any laws, orders or
regulations, relating to any such Hazardous Material, except to the extent
that any of the foregoing actually results from the release or emission of
Hazardous Material by Lessee or its agents or employees in violation of
applicable environmental laws. "Hazardous Material" shall mean any material
which is now or hereafter regulated by any governmental authority which poses
a hazard to the environment or human health. This section and Section 8.(c) of
the Lease constitute the entire agreement of Lessor and Lessee regarding
Hazardous Materials. No other provision of the Lease shall be deemed to apply
thereto.

     11.  Surrender. Lessee's obligations with respect to the surrender of the
Premises shall be fulfilled if Lessee surrenders possession of the Premises in
the condition existing at the Lease Commencement Date, ordinary wear and tear,
acts of God, casualties, condemnation, Hazardous Materials (other than those
released or emitted by Lessee), and alterations or other interior improvements
which it is permitted to surrender at the termination of the Lease, excepted.

     13.  Alterations. Lessee may construct non-structural alterations,
additions and improvements ("Alterations") in the Premises without Lessor's
prior approval, if the cost of any such project does not


                                      -2-
<PAGE>   3
exceed Twenty-Five Thousand Dollars ($25,000). Alterations and Lessee's trade
fixtures, furniture, equipment and other personal property installed in the
Premises ("Lessee's Property") shall at all times be and remain Lessee's
property. Except for Alterations which cannot be removed without structural
injury to the Premises, at any time Lessee may remove Lessee's Property from
the Premises, provided that Lessee repairs all damage caused by such removal.
Lessor shall have no lien or other interest in any item of Lessee's Property.
Lessor shall have no right to require Lessee to remove any alterations unless
it notifies Lessee at the time it consents to such alteration that it shall
require such alteration to be removed.

     14. Repairs. Lessor shall perform and construct, and Lessee shall have no
responsibility to perform or construct, any repair, maintenance or improvements
(a) necessitated by the acts or omissions of Lessor or any other occupant of the
Building, or their respective agents, employees or contractors, (b) for which
Lessor has a right of reimbursement from others, (c) to the structural portions
of the Premises, (d) which could be treated as a "capital expenditure" under
generally accepted accounting principles, (e) to the heating, ventilation, air
conditioning, electrical, water, sewer, and plumbing systems serving the
Premises and the Building, and (f) to any portion of the Building outside of the
demising walls of the Premises. Notwithstanding the foregoing, Lessee shall pay
for its share of the repairs described in subsections (d)-(f) to the extent
such costs are properly included in Operating Expenses.

     17. Utilities and Services. If the Premises should become not reasonably
suitable for Lessee's use as a consequence of cessation of utilities or other
services, interference with access to the Premises, legal restrictions  or the
presence of any Hazardous Material which does not result from Lessee's release
or emission of such Hazardous Material, and in any of the foregoing cases the
interference with Lessee's use of the Premises persists for seven (7) days, then
Lessee shall be entitled to an equitable abatement of rent to the extent of the
interference with Lessee's use of the Premises occasioned thereby. If the
interference persists for more than ninety (90) days, Lessee shall have the
right to terminate the Lease.

     18. Indemnity. Lessor shall not be released or indemnified from, and shall
indemnify, defend, protect and hold harmless Lessee from, all losses, damages,
liabilities, claims, attorneys' fees, costs and expenses arising from the
negligence or willful misconduct of Lessor or its agents, contractors, licensees
or invitees, Lessor's violation of any law, order or regulation, or a breach of
Lessor's obligations or representations under the Lease.

     18.(d) Waiver of Subrogation. The parties hereto release each other and
their respective agents, employees, successors, assignees and subLessees from
all liability for injury to any person or damage to any property that is caused
by or results from a risk which is actually insured against, which is required
to be insured against under the Lease, or which would normally be covered by all
risk property insurance, without regard to the negligence or willful misconduct
of the entity so released. All of Lessor's and Lessee's repair and indemnity
obligations under the Lease shall be subject to the waiver contained in this
paragraph.

     19.(f) Lessor's Insurance. Lessor shall maintain insurance through
individual or blanket policies insuring the building providing "all risk"
coverage for the full replacement cost of the Building, with deductibles and the
form and endorsements of such coverage as selected by Landlord, together with
rental abatement insurance against loss of rent in an amount equal to the amount
of rent for a period of twelve (12) months commencing on the date of loss.
Lessor may also carry such other insurance as Lessor may deem prudent or
advisable, including, without limitation, liability insurance in such amounts
and on such terms as Lessor shall determine. Lessee shall pay to Lessor as a
portion of the Operating Expenses its pro-rata share of the "all risk" and
rental abatement insurance coverages described herein.

     20. Damage. Lessor shall not have the right to terminate the Lease if the
damage to the Building is (a) due to a risk required to be insured against under
Section 19 of the Lease or (b) relatively minor (e.g., repair or restoration
would cost less than ten percent (10%) of the replacement cost of the Building).


                                      -3-
<PAGE>   4
Whenever rent is to be abated under the Lease, all rent and any additional rent
shall be equitably abated based upon the extent to which Lessee's use of the
Premises is diminished.

       24.    Assignment and Subletting. Lessee may, without Lessor's prior
written consent, sublet the Premises or assign the Lease to (a) an entity
controlling, controlled by or under common control with Lessee, (b) a successor
entity related to Lessee by merger, consolidation, nonbankruptcy
reorganization, or government action, or (c) a purchaser of substantially all
of Lessee's assets located in the Premises. A sale or transfer of Lessee's
capital stock shall not be deemed an assignment, subletting or any other
transfer of the Lease or the Premises.

       25.    Subordination. Prior to the Commencement Date, Lessor shall
obtain from any lenders or ground lessors of the Premises a written agreement
in form reasonably satisfactory to Lessee providing for recognition of Lessee's
interests under the Lease in the event of a foreclosure of the lender's
security interest or termination of the ground lease. Further, as a condition
to Lessee's obligation to subordinate its leasehold interest to a ground lease
or instrument of security, Lessor shall obtain from any such ground lessors or
lenders such a recognition agreement.

       38.    Miscellaneous.

       (l)    Approvals. Whenever the Lease requires an approval, consent,
determination, selection or judgment by either Lessor or Lessee, unless another
standard is expressly set forth, such approval, consent, determination,
selection or judgment and any conditions imposed thereby shall be reasonable and
shall not be unreasonably withheld or delayed and, in exercising any right or
remedy hereunder, each party shall at all times act reasonably and in good
faith.

       (m)    Rules and Regulations. Lessee shall not be required to comply
with any new rule or regulation, including any parking area rules and
regulations, unless the same applies non-discriminatorily to all occupants of
the Building, does not unreasonably interfere with Lessee's use of the Premises
or Lessee's parking rights and does not materially increase the obligations or
decrease the rights of Lessee under the Lease.

       (n)    Reasonable Expenditures. Any expenditure by a party permitted or
required under the Lease, for which such party demands reimbursement from the
other party, shall be limited to the fair market value of the goods and
services involved, shall be reasonably incurred, and shall be substantiated by
documentary evidence available for inspection and review by the other party.

In witness whereof, said parties hereunto subscribe their names.

5. RENT:

(a) Monthly Base Rent: Lessee agrees to pay Lessor the Monthly Base Rent for the
Premises (subject to adjustment as hereinafter provided) in advance on the first
day of each calendar month during the Term without prior notice or demand,
except that Lessee agrees to pay the Monthly Base Rent for the first month of
the Term directly to Lessor concurrently with Lessee's delivery of the executed
Lease to Lessor. All rent must be paid to Lessor, without any deduction or
off-set, in lawful money of the United States of America, at the address
designated by Lessor or to such other person or at such other place as Lessor
may from time to time designate in writing. Monthly Base Rent will be adjusted
during Term of this Lease as provided in Exhibit "B".

(b) Additional Rent: All amounts and charges to be paid by Lessee hereunder,
including, without limitation, payments for Operating Expenses, insurance and
repairs, will be considered additional rent for purposes of this Lease, and the
word "rent" as used in this Lease will include all such additional rent unless
the context specifically or clearly implies -that only Monthly Base Rent in
intended.

(c) Late Payments: Late payments of Monthly Base Rent and/or item of additional
rent will be subject to interest and a late charge as provided in Subparagraph
22(f) below.

6. OPERATING EXPENSES:

(a) Operating Expenses and Real Property Taxes. In addition to Monthly Base
Rent, throughout the Term of this Lease, Lessee agrees to pay Lessor as
additional rent in accordance with the terms of this Paragraph 6, Lessee's
Percentage of the sum of the amount (if any) by which operating expenses as
defined in Exhibit "E" for such period exceed base Operating Expenses, and the
amount (if any) by which Real Property Taxes as defined in Exhibit "E" for such
period exceed Base Real Property Taxes.

(b) Estimate Statement. Prior to the Commencement Date and on or about March 1st
of each subsequent calendar year during the Term of this Lease, Lessor will
endeavor to deliver to Lessee a statement ("Estimate Statement") wherein Lessor
will estimate Lessee's Percentage of Operating Expenses for the then current
calendar year. If the estimate of Lessee's Percentage of Operating Expenses in
the Estimate Statement exceeds Lessee's Base Operating Expense, Lessee agrees to
pay Lessor, as "additional rent", one-twelfth (1/12th) of such excess each month
thereafter, beginning with the next installment of rent due, until such time as
Lessor issues a revised Estimate Statement or the Estimate Statement for the
succeeding calendar year; except that, concurrently with the regular monthly
rent payment next due following the receipt of each such Estimate Statement,
Lessee agrees to pay Lessor an amount equal to one monthly installment of such
excess (less any applicable Operating Expenses already paid) multiplied by the
number of months from January, in the current calendar year, to the month of
such rent payment next due, all months inclusive. If at any time during the Term
of this Lease, but not more often than quarterly, Lessor reasonably determines
that Lessee's Percentage of Operating Expenses for the current calendar year
will be greater than the amount set forth in the then current Estimate


                                       5
<PAGE>   10


Statement, Lessor may issue a revised Estimate Statement and Lessee agrees to
pay Lessor, within THIRTY (30) days of receipt of the revised Estimate
Statement, the difference between the amount owed by Lessee under such revised
Estimate Statement and the amount owed by Lessee under the original Estimate
Statement for the portion of the then current calendar year which has expired.
Thereafter Lessee agrees to pay Lessee's Percentage of Operating Expenses based
on such revised Estimate Statement until Lessee receives the next calendar
year's Estimate Statement or a new revised Estimate Statement for the current
calendar year. In the event Lessee's Percentage of Operating Expenses for any
calendar year is less than Lessee's Base Operating Expense, Lessee will not be
entitled to a credit against any rent, additional rent or Lessee's Percentage of
future Operating Expenses payable hereunder.

(c) Actual Statement. By March 1st of each calendar year during the Term of this
Lease, Lessor will also endeavor to deliver to Lessee a statement ("Actual
Statement") which states the actual Operating Expenses for the preceding
calendar year. If the Actual Statement reveals that Lessee's Percentage of the
actual Operating Expenses is more than the total Additional Rent paid by Lessee
for Operating Expenses on account of the preceding calendar year, Lessee agrees
to pay Lessor the difference in a lump sum within THIRTY (30) days of receipt of
the Actual Statement. If the Actual Statement reveals that Lessee's Percentage
of the actual Operating Expenses is less than the Additional Rent paid by Lessee
for Operating Expenses on account of the preceding calendar year, Lessor will
credit any overpayment toward the next monthly installment(s) of Lessee's
Percentage of the Operating Expenses due under this Lease, OR REIMBURSE LESSEE
FOR SUCH AMOUNT, IF THIS LEASE HAS EXPIRED.

(d) Miscellaneous. Any delay or failure by Lessor in delivering any Estimate
Statement or Actual Statement pursuant to this Paragraph 6 will not constitute a
waiver of its right to require an increase in rent nor will it relieve Lessee of
its obligations pursuant to this Paragraph 6, except that Lessee will not be
obligated to make any payments based on such Estimate Statement or Actual
Statement until THIRTY (30) days after receipt of such Estimate Statement of
Actual Statement. Even though the Term has expired and Lessee has vacated the
Premises, when the final determination is made of Lessee's Percentage of the
actual Operating Expenses for the year in which this Lease terminates, Lessee
agrees to promptly pay any increase due over the estimated expenses paid and,
conversely, any overpayment made in the event said expenses decrease shall
promptly be rebated by Lessor to Lessee. Such obligation shall be a continuing
one which will survive the expiration or earlier termination of this Lease.
Prior to the expiration or sooner termination of the Lease Term and Lessor's
acceptance of Lessee's surrender of the Premises, Lessor will have the right to
estimate the actual Operating Expenses for the then current Lease Year and to
collect from Lessee prior to Lessee's surrender of the Premises, Lessee's
Percentage of any excess of such actual Operating Expenses over the estimated
Operating Expenses paid by Lessee in such Lease Year.


7. SECURITY DEPOSIT: Concurrently with Lessee's execution of this Lease, Lessee
will deposit with Lessor the Security Deposit designated in Subparagraph 1(1).
The Security Deposit will be held by Lessor as security for the full and
faithful performance by Lessee of all of the terms, covenants, and conditions of
this Lease to be kept and performed by Lessee during the Term hereof. The
Security Deposit is not, and may not be construed by Lessee to constitute, rent
for the last month or any portion thereof. If Lessee defaults with respect to
any provisions of this Lease including, but not limited to, the provisions
relating to the payment of rent or additional rent, Lessor may (but will not be
required to) use, apply or retain all or any part of the Security Deposit for
the payment of any rent or any other sum in default, or for the payment of any
other amount which Lessor may spend by reason of Lessee's default or to
compensate Lessor for any loss or damage which Lessor may suffer by reason of
Lessee's default. If any portion of the Security Deposit is so used or applied,
Lessee agrees, within ten (10) days after Lessor's written demand therefor, to
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 default
under this Lease. Lessor is not required to keep Lessee's Security Deposit
separate from its general funds, and Lessee is not entitled to interest on such
Security Deposit.


8. USE:

(a) LESSEE'S USE OF THE PREMISES: The Premises may be used for the use or uses
set forth in Subparagraph 1(m) only, and Lessee will not use or permit the
Premises to be used for any other purpose without the prior written consent of
Lessor, which consent Lessor may withhold in its sole and absolute discretion.
Nothing in this Lease will be deemed to give Lessee any exclusive right to such
use in the Project.

any manner obstruct or interfere with the rights or other tenants or occupants
of the Project, or injure or unreasonably annoy them, or use or allow the

Lessee shall not use or allow the Premises to be used for lodging, bathing or

Lease), Lessee agrees not to cause or permit any Hazardous Materials to be

aware of during the Term of this Lease, whether caused by Lessee or any other
persons or entities. In the event of any release of Hazardous Materials caused
or permitted by Lessee or any of Lessee's Parties, Lessor shall have the right,
but not the obligation, to cause Lessee to immediately take all steps Lessor
deems necessary or appropriate to remediate such release and prevent any similar
future release to the satisfaction of Lessor and Lessor's mortgagee(s). At all

other refuse on the Premises except in sanitary containers and agrees to
regularly and frequently remove same from the Premises. Lessee shall keep all
containers or other equipment used for storage of such materials in a clean and

<PAGE>   12



sewage. Lessee shall keep sewage disposal system free of all obstructions and in
good operating condition. If the volume of Lessee's trash becomes excessive in
Lessor's judgment, Lessor shall have the right to charge Lessee for additional
trash disposal services and/or to require that Lessee contract directly for
additional trash disposal services at Lessee's sole cost and expense.


9. NOTICES: Any notice required or permitted to be given hereunder must be in
writing and maybe given by personal delivery (including delivery by overnight

attorney's fees and court costs) resulting from any breach by the indemnifying
party of the foregoing representation, including, without limitation, any claims
that may be asserted by any broker, agent or finder undisclosed by the
indemnifying party. The foregoing mutual indemnity shall survive the expiration
or earlier termination of this Lease. Lessee agrees that Lessor will not
recognize or compensate any third party broker with regards to any renewals
and/or expansions unless such renewal or expansion rights are included within
this Lease at the time of execution by the parties and in Lessor's commission
agreement with the broker(s) specified in Subparagraph 1(o).

11.  SURRENDER; HOLDING OVER:

(a) SURRENDER: The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, shall not constitute a merger, and shall, at the
option of Lessor, operate as an assignment to Lessor of any or all subleases or
subtenancies. Upon the expiration or earlier termination of this Lease, Lessee
agrees to peaceably surrender the Premises to Lessor broom clean and in a state
of good order, repair and condition, ordinary wear and tear and casualty AND
CONDEMNATION damage excepted, with all of Lessee's personal property, fixtures,
and alterations removed from the Premises to the extent required under Paragraph
13 and all damage caused by such removal repaired as required by Paragraph 13.
The delivery of keys to any employee of Lessor or to Lessor's agent or any
employee thereof alone will not be sufficient to constitute a termination of
this Lease or a surrender of the Premises.

(b) HOLDING OVER: If Lessee holds over after the expiration or earlier
termination of the Term, Lessor may, at its option, treat Lessee as a tenant as
sufferance only, and such continued occupancy by Lessee shall be subject to all
of the terms, covenants and conditions of this Lease, so far as applicable,
including the payment of Operating Expenses, except that the Monthly Base Rent
for any month or partial month during which Lessee holds over shall be equal to
one hundred fifty percent (150%) of Monthly Base Rent in effect under this Lease
immediately prior to such holdover. Acceptance by Lessor of rent after such
expiration or earlier termination will not result in a renewal of this Lease. If
Lessee fails to surrender the Premises upon the expiration of this Lease in
accordance with the terms of this Paragraph 11 despite demand to do so by
Lessor, Lessee agrees to promptly indemnity, protect, defend and hold Lessor
harmless from all claims, damages, judgments, suits, causes of action, losses,
liabilities, penalties, finds, expenses and costs (including attorneys' fees and
costs), including, without limitation, costs and expenses incurred by Lessor in
returning the Premises to the condition in which Lessee was to surrender it and
claims made by any succeeding tenant founded on or resulting from Lessee's
failure to surrender the Premises. The provisions of this Subparagraph 11(b)
will survive the expiration or earlier termination of this Lease.

12. TAXES ON LESSEE'S PROPERTY: Lessee agrees to pay before delinquency, all
taxes and assessments (real and personal) levied against Lessee's business
operations or any personal property, improvements, alterations, trade fixtures
or merchandise placed by Lessee in or about the Premises.



                                       8

<PAGE>   13



13. ALTERATIONS: Lessee shall not make any alterations or add any fixtures to
the Premises or any other aspect of the Project, without Lessor's written
consent, which Lessor may withhold in its reasonable but subjective discretion.
All permitted alterations must be performed in compliance with Lessor's standard
rules and regulations regarding alterations, and with all applicable building
codes, rules and regulation laws. All alterations will become the property of
Lessor and will remain upon and be surrendered with the Premises at the end of
the Term of this Lease; provided, however, Lessor may require Lessee to remove
any or all alterations at the expiration or earlier termination of this Lease.
If Lessee fails to remove by the expiration or earlier termination of this Lease
all of its personal property, or any alterations identified by Lessor for
removal, property, or any alterations identified by Lessor for removal, Lessor
may, at its option, treat such failure as a hold-over pursuant to Subparagraph
11(b) above, and/or Lessor may (without liability to Lessee for loss thereof)
treat such personal property and/or alterations as abandoned and, at Lessee's
sole cost and in addition to Lessor's other rights and remedies under this
Lease, at law or in equity: (a) remove and store such items; and/or (b) upon ten
days' prior notice to Lessee, sell, discard or otherwise dispose of all or any
such items at private or public sale for such price as Lessor may obtain or by
other commercially reasonable means. Lessee shall be liable for all costs of
disposition of Lessee's abandoned property and Lessor shall have no liability to
Lessee with respect to any such abandoned property. Lessor agrees to apply the
proceeds of any sale of any such property to any amounts due to Lessor under
this Lease from Lessee (including Lessor's attorneys' fees and other costs
incurred in the removal, storage and/or sale of such items), with any remainder
to be paid to Lessee.

14. REPAIRS:

(a) LESSOR'S OBLIGATIONS: Lessor agrees to repair and maintain the structural
portions of the Building and the plumbing, heating, ventilating, air
conditioning, elevator and electrical systems installed or furnished by Lessor,
unless such maintenance and repairs are (i) attributable to items installed in
Lessee's Premises which are above standard interior improvements (such as, for
example, custom lighting, special HVAC and/or electrical panels or systems,
kitchen or rest room facilities and appliances constructed or installed within
Lessee's Premises) or (ii) caused in part or in whole by the act, neglect or
omission of Lessee, its agents, servants, employees or invitees, in which case
Lessee will pay to Lessor, as additional rent, the reasonable cost of such
maintenance and repairs. Except as provided in this Subparagraph 14(a), Lessor
has no obligation to alter, remodel, improve, repair, decorate or paint the
Premises or any part thereof. LESSOR'S SOLE OBLIGATION WITH RESPECT TO THE
PROVISIONS OF TELEPHONE OR TELECOMMUNICATION SERVICES SHALL BE TO PROVIDE AN
INTERFACE WITH THE TELEPHONE NETWORK AT THE DEMARCATION POINT SUPPLIED BY THE
LOCAL PUBLIC UTILITY AND CABLE PAIRS IN AN AMOUNT CONSISTENT WITH THE
ENGINEERING STANDARDS TO WHICH THE BUILDING WAS DESIGNED. Lessor will not be
liable for any failure to make any repairs or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Lessor by Lessee. Except as
provided in Paragraph 20, Lessee will not be entitled to any abatement of rent
and Lessor will not have any liability by reason of any injury to or
interference with Lessee's business arising from the making of any repairs,
alterations or improvements in or to any portion of the Building or the Premises
or in or to fixtures, appurtenances and equipment therein. Lessee waives the
right to make repairs at Lessor's expense under any laws, statute, ordinance,
rule, regulation, order or ruling (including, without limitation, to the extent
the Premises are located in California, the provisions of California Civil Code
Sections 1941 and 1942 and any successor statutes or laws of a similar nature).


(b) LESSEE'S OBLIGATIONS: Lessee agrees to keep, maintain and preserve the
Premises in good condition and repair consistent with the remainder Building
and, when and if needed, at Lessee's sole cost and expense, to make all repairs
to the Premises and every part thereof. Any such maintenance and repairs will be
performed by Lessor's contractor, or at Lessor's option, by such contractor or
contractors as Lessee may choose from an approved list to be submitted by
Lessor. LESSEE'S MAINTENANCE AND REPAIR OBLIGATION SHALL INCLUDE THE OBLIGATION
TO MAINTAIN AND REPAIR ALL THE WIRE BETWEEN THE DISTRIBUTION TERMINAL ON THE
FLOOR WHERE THE PREMISES ARE LOCATED AND THE TELEPHONE JACK(S) IN THE PREMISES
(SUCH WIRE IS HEREAFTER REFERRED TO AS "NETWORK TERMINATING WIRE") AND ALL
TELEPHONE OR TELECOMMUNICATION WIRING (INCLUDING JACKS) LOCATED WITHIN THE
PREMISES (HEREAFTER REFERRED TO AS "INSIDE WIRE"). Lessee agrees to pay all
costs and expenses incurred in such maintenance and repair within FIFTEEN (15)
days after billing by Lessor or such contractor or contractors. Lessee agrees to
caused any mechanics' liens or other liens arising as a result of work performed
by Lessee of at Lessee's direction to be eliminated as provided in Paragraph 15
below. If Lessee refuses or neglects to repair and maintain the Premises
properly as required hereunder to the reasonable satisfaction of Lessor, Lessor,
at any time following ten (10) days from the date on which Lessor makes a
written demand on Lessee to effect such repair and maintenance, may enter upon
the Premises and make such repairs and/or


                                       9
<PAGE>   14



maintenance, and upon completion thereof, Lessee agrees to pay to Lessor as
additional rent, Lessor's costs for making such repairs plus an amount not to
exceed ten percent (10%) of such costs for overhead, within ten (10) days of
receipt from Lessor of a written itemized bill therefor. Any amounts not
reimbursed by Lessee within such ten (10) day period will amounts not reimbursed
by Lessee within such ten (10) day period will bear interest at the Interest
Rate until paid by Lessee.

15. LIENS: Lessee agrees not to permit any mechanic's, materialmen's or other
liens to be filed against all or any part of the Development, the Building or
the Premises, nor against Lessee's leasehold interest in the Premises, by reason
of or in connection with any repairs, alterations, improvements or other work
contracted for or undertaken by Lessee or any other act or omission of Lessee or
Lessee's agents, employees, contractors, licensees or invitees. At Lessor's
request, Lessee agrees to provide Lessor with enforceable, and final lien
release (or other evidence reasonably requested by Lessor to demonstrate
protection from liens) from all person furnishing labor and/or materials at the
Premises. Lessor will have the right at all reasonable times to post on the
Premises and r record any notices of nonresponsibility which it deems necessary
for protection from such liens. If any such liens are filed, Lessee will, at its
sole cost and expense, promptly cause such liens to be released of record bonded
so that it in longer affects title to the Development, the Building or the
Premises. If lessee fails to cause any such liens to be so released or bonded
within ten (10) days after filing thereof, such failure will be deemed a
material breach by Lessee under the Lease without the benefit of any additional
notice or cure period described in Paragraph 22 below, and Lessor may, without
waiving its rights and remedies based on such breach, and without releasing
Lessee from any of its obligations, cause such liens to be released by any
means it shall deem proper, including payment in satisfaction of the claims
giving rise to such liens. Lessee agrees to pay to Lessor within ten (10) days
after receipt of invoice from Lessor, any sum paid by Lessor to remove such
liens, together with interest at the Interest Rate from the date of such payment
by Lessor.

16. ENTRY BY LANDLORD: Lessor and its employees and agents will at all
reasonable times have the right to enter the Premises to inspect the same, to
supply janitorial service and any other service to be provided by Lessor to
Lessee hereunder, to show the Premises to prospective purchasers or WITHIN THE
LAST THREE (3) MONTHS OF THE TERM, lessees, to post notices of
nonresponsibility, and/or to repair the Premises as permitted or required by
this Lease. In exercising such entry rights, Lessor will endeavor to minimize,
as reasonably practicable, the interference with Lessee' business, and will
provide Lessee with reasonable advance notice of any such entry (except in
emergency situations). Lessor will at all times have and retain a key with which
to unlock all doors in the Premises, excluding Lessee's vaults and safes. Except
in the case of the gross negligence or willful misconduct of Lessor, any entry
to the Premises obtained by Lessor will not be construed or deemed to be a
forcible or unlawful entry into the Premises, or an eviction of Lessee from the
Premises and Lessor will not be liable to Lessee for any damages or losses
resulting from any such entry.

17. UTILITIES AND SERVICES: Throughout the Term of the Lease so long as the
Premises are occupied, Lessor agrees to furnish or cause to be furnished to the
premises the utilities and services described in the Standards for Utilities and
Services attached hereto as Exhibit "F" Lessor will not be liable to Lessee for
any failure to furnish any of the foregoing utilities and services if such
failure is caused by all or any of the following: (i) accident, breakage or
repairs; (ii) strikes, lockouts or other labor disturbance or labor dispute of
any character; (iii) governmental regulation, moratorium or other governmental
action or inaction; (iv) inability despite the exercise of reasonable diligence
to obtain electricity, water or fuel; or (v) any other caused beyond Lessor's
reasonable control. In addition, in the event of any stoppage or interruption of
services or utilities, Lessee shall not be entitled to any abatement or
reduction of rent (except as expressly provided in Subparagraphs 20(f) or 21(b)
if such failure results from a damage or taking described therein), no eviction
of Lessee will result from such failure and Lessee will not be relieved from the
performance of any covenant or agreement in this Lease because of such failure.
In the event of any failure, stoppage or interruption thereof, Lessor agrees to
diligently attempt to resume service promptly. If Lessee requires or utilizes
more water or electrical power than is considered reasonable or normal by
Lessor, Lessor may at its option require Lessee to pay, as additional rent, the
cost, as fairly determined by Lessor, incurred by such extraordinary usage
and/or Lessor may install separate meter(s) for the Premises, at Lessee's sole
expense, and Lessee agrees thereafter to pay all shares of the utility providing
service.

18. ASSUMPTION OF RISK AND INDEMNIFICATION:

(a) ASSUMPTION OF RISK: Lessee, as a material part of the consideration to
Lessor, agrees that neither Lessor nor any Lessor Indemnified Parties (as
defined in Subparagraph 8(c) above) will be liable to Lessee for, and Lessee
expressly assumes the risk of and waives any and all claims it may have against
Lessor or any Lessor Indemnified Parties with


                                       10
<PAGE>   15




respect to, (i) any and all damage to property or injury to persons in, upon or
about the premises, the Building or the Development resulting from any act or
omission (except for the grossly negligent or intentionally willful act or
omission of Lessor or its agent or employees), (ii) any such damage caused by
other tenants or persons in or about the Building or the Development, or caused
by quasi-public work, (iii) any damage to property entrusted to employees of the
Building, (iv) any loss of or damage to property by theft or otherwise, or (v)
any injury or damage to person or property resulting from any casualty,
explosion, falling plaster or other masonry or glass, steam, gas, electricity,
water or rain which may leak from any part of the Building or any other portion
of the Development or from the roof, street or subsurface or from any other
place, or resulting from dampness. Neither Lessor nor any Lessor Indemnified
Parties will be liable for consequential damages arising out of any loss of the
use of the Premises or any equipment or facilities therein by Lessee or any
Lessee Parties or for interference with light. Lessee agrees to give prompt
notice to Lessor in case of fire or accidents in the Premises or the Building,
or of defects therein or in the fixtures or equipment.

(b) INDEMNIFICATION: Lessee will be liable for, and agrees to the maximum extent
permissible under applicable law, to promptly indemnify, protect, defend and
hold harmless Lessor and all Lessor Indemnified Parties from and against, any
and all claims, damages, judgments, suits, causes of action, losses,
liabilities, penalties, fines, expenses and costs, including attorney's fees and
court costs (collectively, "Indemnified Claims"), arising or resulting from (i)
any act or omission of Lessee or any Lessee Parties (as defined in Subparagraph
8(c) above); (ii) the use of the Premises and Common Areas and conduct of
Lessee's business by Lessee or any Lessee Parties, or any other activity, work
or thing done, permitted or suffered by Lessee or any Lessee Parties, in or
about the Premises, the Building or elsewhere within the Development; and/or
(iii) any default by Lessee or any obligations on Lessee's part to be performed
under the terms of this Lease. In case any action or proceeding is brought
against Lessor or any Lessor Indemnified Parties by reason of any such
Indemnified Claims, Lessee, upon notice from Lessor, agrees to promptly defend
the same at Lessee's sole cost and expense by counsel approved in writing by
Lessor, which approval Lessor will not unreasonably withhold.

(c) SURVIVAL; NO RELEASE OF INSURERS: Lessee's indemnification obligations under
Subparagraph 18(b) will survive the expiration or earlier termination of this
Lease. Lessee's covenants, agreements and indemnification obligation in
Subparagraphs 18(a) and 18(b) above, are not intended to and will not relieve
any insurance carrier of its obligations under policies required to be carried
by Lessee pursuant to the provisions of this Lease.

19. INSURANCE:

(a) LESSEE'S INSURANCE: On or before the earlier to occur of (i) the
Commencement Date, or (ii) the date Lessee commences any work of any type in the
Premises pursuant to this Lease (which may be prior to the Commencement Date),
and continuing throughout the entire Term hereof and any other period of
occupancy, Lessee agrees to keep in full force and effect, at it sole cost and
expense, the insurance specified on Exhibit "D" attached hereto. Lessor
reserves the right to require any other form or forms of insurance as Lessee or
Lessor or any mortgagees of Lessor may reasonably require from time to time in
form, in amounts, and for insurance risks against which, a prudent lessee would
protect itself, but only to the extent coverage for such risks and amounts are
available in the insurance market at commercially acceptable rates. Lessor makes
no representation that the limits of liability required to be carried by Lessee
under the terms of this Lease are adequate to protect Lessee's interests and
Lessee should obtain such additional insurance or increased liability limits as
Lessee deems appropriate.

(b) SUPPLEMENTAL LESSEE INSURANCE REQUIREMENTS: All polices must be in a form
reasonably satisfactory to Lessor and issued by an insurer admitted to do
business in the state in which the Building is located. All policies must be
issued by insurers with a policyholder rating of "A" and a financial rating of
"X" in the most recent version of Best's Key Rating Guide. All policies must
contain a requirement to notify Lessor (and Lessor's property manager and any
mortgagees or ground lessors of Lessor who are named as additional insurers, if
any) in writing not less than thirty (30) days prior to any material change,
reduction in coverage, cancellation or other termination thereof. Lessee agrees
to deliver to Lessor, as soon as practicable after placing the required
insurance, but in any event within the time frame specified in Subparagraph
19(a) above, certificate(s) of insurance and/or if required by Lessor, certified
copies of each policy evidencing the existence of such insurance and Lessee's
compliance with the provisions of this Paragraph 19. Lessee agrees to cause
replacement polices or certificates to be delivered to Lessor not less than
thirty (30) days prior to the expiration of any such policy or policies. If any
such initial or replacement polices or certificates are not furnished within the
time(s) specified herein, Lessor will have the right, but not the obligation, to
obtain such insurance as Lessor deems necessary to protect Lessor's interests at
Lessee's expense. If Lessor obtains any insurance that is the


                                       11
<PAGE>   16



responsibility of Lessee under this Paragraph 19, Lessor agrees to deliver to
Lessee a written statement setting forth the cost of any such insurance and
showing in reasonable detail the manner in which it has been computed and Lessee
agrees to promptly reimburse Lessor for such costs as additional rent. General
Liability and Automobile Liability policies under Paragraphs 1 and 5 of Exhibit
"D" attached hereto must name Lessor and Lessor's property manager (and at
Lessor's request, Lessor's mortgagees and ground lessors of which Lessee has
been informed in writing) as additional insured and must also contain a
provision that the insurance afforded by such policy is primary insurance and
any insurance carried by Lessor and Lessor's property manager of Lessor's
mortgagees or ground lessors, if any, will be excess over and non-contributing
with Lessee's insurance. LESSEE SHALL DELIVER TO LESSOR, ALONG WITH THE
CERTIFICATE OF INSURANCE MENTIONED ABOVE, AN ENDORSEMENT LISTING LESSOR AS
ADDITIONAL INSURED.

(c) LESSEE'S USE: Lessee will not keep, use, sell or offer for sale in or upon
the Premises any article which may be prohibited by any insurance policy
periodically in force covering the Building or the Development Common Areas. If
Lessee's occupancy or business in, or on, the premises, whether or not Lessor
has consented to the same, results in any increase in premiums for the insurance
periodically carried by Lessor with respect to the Building or the Development
or results in the need for Lessor to maintain special or additional insurance,
Lessee agrees to pay Lessor the cost of any such increase in premiums or special
or additional coverage as additional rent within ten (10) days after being
billed therefor by Lessor. Lessee agrees to promptly comply with all reasonable
requirements of the insurance authority or any present or future insurer
relating to the Premises.

(d) CANCELLATION OF LESSOR'S POLICIES: If any of Lessor's insurance policies are
canceled or cancellation is threatened or the coverage reduced or threatened to
be reduced in any way because of the use of the Premises or any part thereof by
Lessee or any assignee or subtenant of Lessee or by anyone Lessee permits on the
Premises and, if Lessee fails to remedy the condition giving rise to such
cancellation, threatened cancellation, reduction of coverage, threatened
reduction of coverage, increase in premiums, or threatened increase in premiums,
within forty-eight (48) hours after notice thereof, Lessee will be deemed to be
in material default of this Lease and Lessor may, at its option, either
terminate this Lease or enter upon the Premises and attempt to remedy such
condition, and Lessee shall promptly pay Lessor the reasonable costs of such
remedy as additional rent. If Lessor is unable, or elects not to remedy such
condition, then Lessor will have all of the remedies provided for in this Lease
in the event of a default by Lessee.

(e) WAIVER OF SUBROGATION: Lessee's property and liability insurance shall
contain a clause whereby the insurer waives all rights of recovery by way of
subrogation against Lessor. Lessee shall also obtain and furnish evidence to
Lessor of the waiver by Lessee's worker's compensation insurance carrier of all
rights or recovery by way of subrogation against Lessor.

20. DAMAGE OR DESTRUCTION:

(a) PARTIAL DESTRUCTION: If the Premises or the Building are damaged by fire or
other casualty to an extent not exceeding twenty-five percent (25%) of the full
replacement cost thereof, and Lessor's contractor reasonably estimates in a
writing delivered to Lessor and Lessee that the damage thereto may be repaired,
reconstructed or restored to substantially its condition immediately prior to
such damage within one hundred eighty (180) days from the date of such casualty,
and Lessor will receive insurance proceeds sufficient to cover the costs of such
repairs, reconstruction and restoration (including proceeds from Lessee and/or
Lessee's insurance which Lessee is required to deliver to Lessor pursuant to
Subparagraph 20(e) below to cover Lessee's obligation for the costs of repair,
reconstruction and restoration of any portion of the tenant improvements and any
alterations for which Lessee is responsible under this Lease), then Lessor
agrees to commence and proceed diligently with the work of repair,
reconstruction and restoration and this Lease will continue in full force and
effect.

(b) SUBSTANTIAL DESTRUCTION: Any damage or destruction to the Premises or the
Building which Lessor is not obligated to repair pursuant to Subparagraph 20(a)
above will be deemed a substantial destruction. In the event of a substantial
destruction, Lessor may elect to either: (i) repair, reconstruct and restore the
portion of the Building or the Premises damaged by such casualty, in which case
this Lease will continue in full force and effect, subject to Lessee's
termination right contained in Subparagraph 20(d) below; or (ii) a notice from
Lessor's insurance company that there is funds to



                                       12
<PAGE>   17


repair damage (iii) terminate this Lease effective as of the date which is
thirty (30) days after Lessee's receipt of Lessor's election to so terminate.

(c) NOTICE: Under any of the conditions of Subparagraph 20(a) or (b) above,
Lessor agrees to give written notice to Lessee of its intention to repair or
terminate, as permitted in such paragraphs, within the earlier of sixty (60)
days after the occurrence of such casualty, or fifteen (15) days after Lessor's
receipt of the estimate from Lessor's contractor (the applicable time period to
be referred to herein as the "Notice Period").

(d) TERMINATION RIGHTS: If Lessor elects to repair, reconstruct and restore
pursuant to Subparagraph 20(b)(i) hereinabove, and if Lessor's contractor
estimates that as a result of such damage, Lessee cannot be given reasonable use
of and access to the Premises within three hundred sixty-five (365) days after
the date of such damage, then either Lessor or Lessee may terminate this Lease
effective upon delivery of written notice to the other within ten (10) days
after Lessor delivers notice to Lessee of its election to so repair, reconstruct
or restore.

(e) LESSEE'S COSTS AND INSURANCE PROCEEDS: In the event of any damage or
destruction of all or any part of the Premises, Lessee agrees to immediately (i)
notify Lessor thereof, and (ii) deliver to Lessor all property insurance
proceeds received by Lessee with respect to any tenant improvements installed by
or at the cost of Lessee and any alterations, but excluding proceeds for
Lessee's furniture, trade fixtures, equipment and other personal property,
whether or not this Lease is terminated as permitted in this Paragraph 20, and
Lessee hereby assigns to Lessor all rights to receive such insurance proceeds.
If, for any reason (including Lessee's failure to obtain insurance for the full
replacement cost of any Lessee Improvements installed by or at the cost of
Lessee and any alterations from any and all casualties), Lessee fails to receive
insurance proceeds covering the full replacement cost of any such tenant
improvements and any alterations which are damaged, Lessee will be deemed to
have self-insured the replacement cost of such item's, and upon any damage or
destruction thereto, Lessee agrees to immediately pay to Lessor the full
replacement cost of such item's, less any insurance proceeds actually received
by Lessor from Lessor's or Lessee's insurance with respect to such item's.

(f) ABATEMENT OF RENT: In the event of any damage, repair, reconstruction and/or
restoration described in this Paragraph 20, rent will be abated or reduced, as
the case may be, from the date of such casualty, in proportion to the degree to
which Lessee's use of the Premises is impaired during such period of repair
until such use is restored. Except for abatement of rent as provided
hereinabove, Lessee will not be entitled to any compensation or damages for loss
of, or interference with, Lessee's business or use or access of all or any part
of the Premises or for lost profits or any other consequential damages of any
kind or nature, which result from any such damage, repair, reconstruction or
restoration.

(g) DAMAGE NEAR END OF TERM: Lessor and Lessee shall each have the right to
terminate this Lease if any damage to the Premises or the Building occurs during
the last twelve (12) months of the Term of this Lease where Lessor's contractor
estimates in writing delivered to Lessor and Lessee the repair, reconstruction
or restoration of such damage cannot be complete within sixty (60) days after
the date of such casualty or during the balance of the term. If either party
desires to terminate this Lease under this Subparagraph (1), it shall provide
written notice to the other party of such election within ten (10) days after
receipt of Lessor's contractor's repair estimates.

(h) WAIVER OF TERMINATION RIGHT: Lessor and Lessee agree that the foregoing
provisions of this Paragraph 20 are to govern their respective rights and
obligations in the event of any damage or destruction and supersede and are in
lieu of the provisions of any applicable law, statute, ordinance, rule,
regulation, order or ruling now or hereafter in force which provide remedies for
damage or destruction of leased premises (including, without limitation, to the
extent the Premises are located in California, the provisions of California
Civil Code Section 1932, Subsection 2, and Section 1933, Subsection 4 and any
successor statute or laws of a similar nature).

21. EMINENT DOMAIN:

(a) SUBSTANTIAL TAKING: If the whole of the Premises, or such part thereof as
shall substantially interfere with Lessee's use and occupancy of the Premises,
as contemplated by this Lease, is taken for any public or quasi-public purpose
by any lawful power or authority by exercise of the right of appropriation,
condemnation or eminent domain, or sold to prevent such taking, either party
will have the right to terminate this Lease effective as of the date possession
is required to be surrendered to such authority.


                                       13
<PAGE>   18


(b) PARTIAL TAKING; ABATEMENT OF RENT: In the event of a taking of a portion of
the Premises which does not substantially interfere with Lessee's use and
occupancy of the Premises, then, neither party will have the right to terminate
this Lease and Lessor will thereafter proceed to make a functional unit of the
remaining portion of the Premises (but only to the extent Lessor receives
proceeds therefor from the condemning authority), and rent will be abated with
respect to the part of the premises which Lessee is deprived of on account of
such taking. Notwithstanding the immediately preceding sentence to the contrary,
if any part of the Building or the Development is taken (whether or not such
taking substantially interferes with Lessee's use of the Premises), Lessor may
terminate this Lease upon thirty (30) day's prior written notice to Lessee.

(c) CONDEMNATION AWARD: In connection with any taking of the Premises of the
Building, Lessor will be entitled to receive the entire amount of any award
which may be made or given in such taking or condemnation, without deduction or
apportionment for any estate or interest of Lessee, it being expressly
understood and agreed by Lessee that no portion of any such award will be
allowed or paid to Lessee for any so-called bonus or excess value will be the
sole property of Lessor. Lessee agrees not to assert any claim against Lessor or
the taking authority for any compensation because of such taking (including any
claim for bonus or excess value of this Lease); provided, however, if any
portion of the Premises is taken, Lessee will have the right to recover from the
condemning authority (but not from Lessor) any compensation as may be separately
awarded or recoverable by Lessee for the taking of Lessee's furniture, fixtures,
equipment and other personal property within the Premises, for Lessee's
relocation expenses, and for any loss of goodwill or other damage to Lessee's
business by reason of such taking.

(d) TEMPORARY TAKING: In the event of taking of the Premises or any part thereof
for temporary use, (i) this Lease will remain unaffected thereby and rent will
not abate, and (ii) Lessee will be entitled to receive such portion or portions
of any award made for such use with respect to the period of the taking which is
within the Term, provided that if such taking remains in force at the expiration
or earlier termination of this Lease, Lessee will then pay to Lessor a sum equal
to the reasonable cost of performing Lessee's obligations under Paragraph 11
with respect to surrender of the Premises and upon such payment Lessee will be
excused from such obligations. For purpose of this Subparagraph 21(d), a
temporary taking shall be defined as a taking for a period of ninety (90) days
or less.

22. DEFAULTS AND REMEDIES:

(a) DEFAULTS: The occurrence of any one or more of the following events will be
deemed a default by Lessee:

(i) The abandonment or vacating of the Premises by Lessee.

(ii) The failure by Lessee to make any payment of rent or additional rent or any
other payment required to be made by Lessee hereunder, as and when due, where
such failure continues for a period of three (3) days after written notice
thereof from Lessor to Lessee; provided, however, that any such notice will be
in lieu of, and not in addition to, any notice required under applicable law
(including, without limitation, to the extent the Premises are located in
California, the provisions of California Code of Civil Procedure Section 1161
regarding unlawful detainer actions or any successor statute or law of a similar
nature).

(iii) The failure by Lessee to observe or perform any of the express or implied
covenants or provisions of this Lease to be observed or performed by Lessee,
other than as specified in Subparagraph 22(a) (i) or (ii) above, where such
failure continues for a period of five (5) days after written notice thereof
from Lessor to Lessee. The provisions of any such notice will be in lieu of, and
not in addition to, any notice required under applicable law (including, without
limitation, to the extent the Premises are located in California, California
Code of Civil Procedure section 1161 regarding unlawful detainer actions and any
successor statute of similar law). If the nature of Lessee's default is such
that more than five (5) days are reasonably required for its cure, then Lessee
will not be deemed to be in default if Lessee commences such cure within such
five (5) days period and thereafter diligently prosecutes such cure to
completion.

(iv) (A) the making by Lessee of any general assignment for the benefit of
creditors; (B) 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 sixty (60) days); (C) 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 (D) the attachment,


                                       14
<PAGE>   19



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.

(b) LESSOR'S REMEDIES; TERMINATION: In the event of any default by Lessee, in
addition to any other remedies available to Lessor at law or in equity under
applicable law, Lessor will have the immediate right and option to terminate
this Lease and all rights of Lessee hereunder. If Lessor elects to terminate
this Lease then, to the extent permitted under applicable law, Lessor may
recover from Lessee: (i) the worth at the time of award of any unpaid rent which
had been earned at the time of such termination; plus (ii) the worth at the time
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 rent loss that
Lessee proves could have been reasonably avoided; plus (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 rent loss that Lessee proves
could be reasonably avoided; plus (iv) any other amount necessary to compensate
Lessor for all the detriment proximately caused by Lessee's failure to perform
its obligations under this Lease or which, in the ordinary course of things,
results therefrom including, but not limited to: attorneys' fees and costs
brokers' commissions; the costs of refurbishment, alterations, renovation and
repair of the Premises, and removal (including the repair of any damage caused
by such removal) and storage (or disposal) of Lessee's personal property,
equipment, fixtures, alterations, the tenant improvements and any other items
which Lessee is required under this Lease to remove but does not remove, as well
as the unamortized value of any free rent, reduced rent, free parking, reduced
rate parking and any tenant improvement allowance or other costs or economic
concessions provided, paid, granted or incurred by Lessor pursuant to this
Lease. The total value of such concessions and multiplying such value by a
fraction, the numerator of which is the number of months of the Lease Term not
yet elapsed as of the date on which the Lease is terminated, and the denominator
of which is the total number of months of the Lease Term. As used in
Subparagraphs 22(b)(iii) above, the "worth at the time of award" is 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%).

(c) RIGHT TO RECOVER RENT AS IT BECOMES DUE: Lessor may exercise the remedy
described in California Civil Code Section 1951.4 (lessor may continue lease in
effect after lessee's breach and abandonment, and recover rent as it becomes
due, if lessee has right to sublet or assign, subject only to reasonable
limitations). Lessee hereby specifically acknowledges and agrees that the
limitations on its right to sublet or assign, as set forth in Paragraph 24 or
the Lease, are reasonable.

(d) LESSOR'S REMEDIES; RE-ENTRY RIGHTS: In the event of any default by Lessee,
in addition to any other remedies available to Lessor under this Lease, at law
or in equity, Lessor will also have the right, with or without terminating this
Lease, to re-enter the Premises and remove all persons and property from the
Premises; such property may be removed and stored in a public warehouse or
elsewhere and/or disposed of at the sole cost and expense of and for the account
of Lessee in accordance with the provisions of Paragraph 13 of this Lease or any
other procedures permitted by applicable law. No re-entry or taking possession
of the Premises by Lessor pursuant to this Subparagraph 22(c) will be construed
as an election to terminate this Lease unless a written notice of such intention
is given to Lessee or unless the termination thereof is decreed by a court of
competent jurisdiction.

(e) LESSOR'S REMEDIES; RE-LETTING: If Lessor does not elect to terminate this
Lease, Lessor may from time to time, without terminating this Lease, either
recover all rent as it becomes due or relet the Premises or any part thereof on
terms and conditions as Lessor in its sole and absolute discretion may deem
advisable with the right to make alterations and repairs to the Premises in
connection with such reletting. If Lessor elects to relet the Premises, then
rents received by Lessor from such reletting will be applied: first, to the
payment of any indebtedness other than rent due hereunder from Lessee to Lessor;
second, to the payment of any cost of such reletting; third, to the payment of
the cost of any alterations and repairs to the Premises incurred in connection
with such reletting; fourth, to the payment of rent due and unpaid hereunder and
the residue, if any, will be held by Lessor and applied to payment of future
rent as the same may become due and payable hereunder. Should that portion of
such rents received from such reletting during any month, which is applied to
the payment of rent hereunder, be less than the rent payable during that month
by Lessee hereunder, then Lessee agrees to pay such deficiency to Lessor
immediately upon demand therefor by Lessor. Such deficiency will be calculated
and paid monthly.

(f) LESSOR'S REMEDIES; PERFORMANCE FOR LESSEE: All covenants and agreements to
be performed by Lessee under any of the terms of this Lease are to be performed
by Lessee at Lessee's sole cost and expense and without any abatement of



                                       15
<PAGE>   20
rent. If Lessee fails to pay any sum of money owed to any party other than
Lessor, for which its is liable under this Lease, or if Lessee fails to perform
any other act on its part to be performed hereunder, and such failure continues
for ten (10) days after notice thereof by Lessor, Lessor may, without waiving
or releasing Lessee from its obligations, but shall not be obligated to, make
any such payment or perform any such other act to be made or performed by
Lessee. Lessee agrees to reimburse Lessor upon demand for all sums so paid by
Lessor and all necessary incidental costs, together with interest thereon at
the Interest Rate, from the date of such payment by Lessor until reimbursed by
Lessee. This remedy shall be in addition to any other right or remedy of Lessor
set forth in this Paragraph 22.

(g) LATE PAYMENT: If Lessee fails to pay any installment of rent within ten
(10) days of when due or if Lessee fails to make any other payment for which
Lessee is obligated under this Lease within ten (10) days of when due, such
late amount will accrue interest at the Interest Rate and Lessee agrees to pay
Lessor as additional rent such interest on such amount from the date such
amount becomes due until such amount is paid. In addition, Lessee agrees to pay
to Lessor concurrently with such late payment amount, as additional rent, a
late charge equal to ten percent (10%) of the amount due to compensate Lessor
for the extra costs Lessor will incur as a result of such late payment.
Acceptance of any such interest and late charge will not constitute a waiver of
the Lessee's default with respect to the overdue amount, or prevent Lessor from
exercising any of the other rights and remedies available to Lessor. If Lessee
incurs a late charge more than three (3) times in any period of twelve (12)
months during the Lease Term, then, notwithstanding that Lessee cures the late
payments for which such late charges are imposed, Lessor will have the right to
require Lessee thereafter to pay all installments of Monthly Base Rent
quarterly in advance throughout the remainder of the Lease Term.

(h) RIGHTS AND REMEDIES CUMULATIVE: All rights, options and remedies of Lessor
to the extent permitted by applicable law contained in this Lease will be
construed and held to be cumulative, and no one of them will be exclusive of
the other, and Lessor shall have the right to pursue any one or all of such
remedies or any other remedy or relief which may be provided by law or in
equity, whether or not state in this Lease. Nothing in this Paragraph 22 will
be deemed to limit or otherwise affect Lessee's indemnification of Lessor
pursuant to any provision of this Lease.

23. LESSOR'S DEFAULT: Lessor will not be in default in the performance of any
obligation required to be performed by Lessor under this Lease unless Lessor
fails to perform such obligation within thirty (30) days after the receipt of
written notice from Lessee specifying in detail Lessor's failure to perform;
provided however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance, then Lessor will not be
deemed in default if it commences such performance within such thirty (30) day
period and thereafter diligently pursues the same to completion. Upon any
default by Lessor, Lessee may exercise any of its rights provided at law or in
equity subject to the limitations on liability set forth in Paragraph 35 of
this Lease.

24. ASSIGNMENT AND SUBLETTING:

(a) RESTRICTION ON TRANSFER: Except as expressly provided in this Paragraph 24,
Lessee will not, either voluntarily or by operation of law, assign or encumber
this Lease or any interest herein or sublet the Premises or any part thereof,
or permit the use or occupancy of the Premises by any party other than Lessee
(any such assignment, encumbrance, sublease or the like will sometimes be
referred to as a "Transfer"), without the prior written consent of Lessor,
which consent Lessor will not unreasonably withhold. For purposes of this
Paragraph 24, if Lessee is a corporation, partnership or other entity, any
transfer, assignment, encumbrance or hypothecation of twenty-five percent (25%)
or more (individually or in the aggregate) of any stock or other ownership
interest in such entity, and/or any transfer assignment, hypothecation or
encumbrance of any controlling ownership or voting interest in such entity,
will be deemed a Transfer and will be subject to all of the restrictions and
provisions contained in the Paragraph 24. NOTWITHSTANDING THE FOREGOING, LESSEE
MAY UPON A FIFTEEN (15) DAY WRITTEN NOTICE, AND LEGAL WRITTEN DOCUMENTATION TO
LESSOR, MAY SUBLET THE PREMISES OR ASSIGN THE LEASE TO (A) AN ENTITY
CONTROLLING, CONTROLLED BY OR UNDER COMMON CONTROL WITH LESSEE, (B) A SUCCESSOR
ENTITY RELATED TO LESSEE BY MERGER, CONSOLIDATION, NONBANKRUPTCY
REORGANIZATION, OR GOVERNMENT ACTION, OR (C) A PURCHASER OF SUBSTANTIALLY ALL
LESSER'S ASSETS LOCATED IN THE PREMISES. A SALE OR TRANSFER OF LESSEE'S CAPITAL
STOCK SHALL NOT BE DEEMED AN ASSIGNMENT, SUBLETTING OR ANY OTHER TRANSFER OF
THE LEASE OR THE PREMISES.

(b) TRANSFER NOTICE: If Lessee desires to effect a Transfer, then at least
thirty (30) days prior to the date when Lessee desires the Transfer to be
effective (the "Transfer Date"), Lessee agrees to give Lessor a notice (the
"Transfer Notice").

                                       16
<PAGE>   21
stating the name, address and business of the proposed assignee, sublessee or
other transferee (sometimes referred to hereinafter as "Transferee"),
reasonable information (including references) concerning the character,
ownership and financial condition of the proposed Transferee, the Transfer
Date, any ownership or commercial relationship between Lessee and the proposed
Transferee, and the consideration and all other material terms and conditions
of the proposed Transfer, all in such detail as Lessor may reasonably require.

(c) LESSOR'S OPTIONS: Within ten (10) days of Lessor's receipt of any
Transfer Notice, and any additional information requested by Lessor concerning
the proposed Transferee's financial responsibility, Lessor will notify Lessee
of its election to do one of the following: (i) consent to the proposed
Transfer subject to such reasonable conditions as Lessor may impose in
providing such consent; (ii) refuse such consent, which refusal shall be on
reasonable grounds; or (iii) terminate this Lease as to all or such portion of
the Premises which is proposed to be sublet or assigned and recapture all or
such portion of the Premises for reletting by Lessor.

(d) ADDITIONAL CONDITIONS: A condition to Lessor's consent to any Transfer of
this Lease will be the delivery to Lessor or a true copy of the fully executed
instrument of assignment, sublease, transfer or hypothecation, in form and
substance reasonably satisfactory to Lessor. Lessee agrees to pay to Lessor, as
additional rent, all sums and other consideration payable to and for the
benefit of Lessee by the assignee or sublessee in excess of the rent payable
under this Lease for the same period and portion of the Premises. In
calculating excess rent or other consideration which may be payable to Lessor
under this paragraph, Lessee will be entitled to deduct commercially reasonable
third party brokerage commissions and attorneys' fees and other amounts
reasonably and actually expended by Lessee in connection with such assignment
or subletting if acceptable written evidence of such expenditures is provided
to Lessor. No Transfer will release Lessee of Lessee's obligations under this
Lease or alter the liability of Lessees to pay the rent and to perform all
other obligations to be performed by Lessee hereunder. Lessor may require that
any Transferee (i) remit directly to Lessor on a monthly basis, all monies due
Lessee by said Transferee and (ii) assume the obligations of Lessee hereunder
occurring after the date of transfer. Consent by Lessor to one Transfer will
not be deemed consent to any subsequent Transfer. In the event of default by
any Transferee 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 such Transferee or successor. If
Lessee effects a Transfer or requests the consent of Lessor to any Transfer
(whether or not such Transfer is consummated), then, upon demand, Lessee agrees
to pay Lessor a non-refundable administrative fee of Two Hundred Fifty Dollars
($250.00), plus Lessor's reasonable attorneys' fees.

25. SUBORDINATION: Without the necessity of any additional document being
executed by Lessee for the purpose of effecting a subordination, and at the
election of Lessor or any mortgagee or beneficiary with a deed of trust
encumbering the Building and/or the Development, or any lessor of a ground or
underlying lease with respect to the Building, this Lease will be subject and
subordinate at all times to: (i) all ground lease or underlying leases which
may now exist or hereafter be executed affecting the Building; and (ii) the
lien of any mortgage or deed of trust which may now exist or hereafter be
executed for which the Building, the Development or any leases thereof, of
Lessor's interest and estate in any of said items, is specified as security.
Notwithstanding the foregoing, Lessor reserves the right to subordinate any
such ground leases or underlying leases or any such liens to this Lease. If any
such ground lease or underlying lease terminates for any reason or any such
mortgage or deed of trust is foreclosed or a conveyance in lieu of foreclosure
is made for any reason, at the election of Lessor's successor in interest,
Lessee agrees to attorn to and become the lessee of such successor in which
event Lessee's right to possession of the Premises will not be disturbed as
long as Lessee is not in default under this Lease. Lessee hereby waives its
rights under any law which gives or purports to give Lessee any right to
terminate or otherwise adversely affect this Lease and the obligations of
Lessee hereunder in the event of any such foreclosure proceeding of sale.
Lessee covenants and agrees to execute and deliver, upon demand by Lessor and
in the form reasonably required by Lessor, any additional documents evidencing
the priority or subordination of this Lease and Lessee's attornment agreement
with respect to any such ground lease or underlying leases or the lien of any
such mortgage or deed of trust. If Lessee fails to sign and return any such
documents within ten (10) days of receipt, Lessee will be in default hereunder.

26. ESTOPPEL CERTIFICATE: Within ten (10) days following any written request
which Lessor may make from time to time, Lessee agrees to execute and deliver
to Lessor an estoppel certificate as may reasonably be required by Lessor.
Lessor and Lessee intend that any statement delivered pursuant to the Paragraph
26 may be relied upon by any mortgagee, beneficiary, purchaser or prospective
purchaser of the Building or any interest herein. Lessee's failure to deliver
such statement within such time will be conclusive upon Lessee (i) that this
Lease is in full force and effect,

                                      17
<PAGE>   22
without modification except as may be represented by Lessor, (ii) that there
are no incurred defaults in Lessor's performance, and (iii) that not more than
one (1) month's rent has been paid in advance. Without limiting the foregoing,
if Lessee fails to deliver any such statement within such ten (10) day period,
Lessor may deliver to Lessee an additional request for such statement and
Lessee's failure to deliver such statement to Lessor within ten (10) days after
delivery of such additional request will constitute a default under this Lease.
Lessee agrees to indemnify and protect Lessor from and against any and all
claims, damages, losses, liabilities and expenses (including attorneys' fees
and costs) attributable to any failure by Lessee to timely deliver any such
estoppel certificate to Lessor as required by this Paragraph 26.

27. BUILDING PLANNING: If Lessor requires the Premises for use in conjunction
with another suite or for other reasons connected with the planning program for
the Building or the Development, Lessor will have the right, upon sixty (60)
days' prior written notice to Lessee, to move Lessee to other space in the
Building of substantially similar size as the Premises, and with lessee
improvements of substantially similar age, quality and layout as then existing
in the Premises. Any such relocation will be at Lessor's cost and expense,
including the cost of providing such substantially similar lessee improvements
(but not any furniture or personal property) and Lessee's reasonable moving,
telephone installation and stationary reprinting cost. If Lessor so relocates
Lessee, the terms and conditions of this Lease will remain in full force and
effect an apply to the new space, except that (a) a revised Exhibit "A-1" will
become part of this Lease and will reflect the location of the new space, (b)
Paragraph 1 of this Lease will be amended to include and state all correct data
as to the new space, (c) the new space will thereafter be deemed to be the
"Premises", and (d) all economic terms and conditions (e.g. rent, total Base
Operating Expense, etc.) will be adjusted on a per square foot basis based on
the total number of rentable square feet of area contained in the new space.
Lessor and Lessee agree to cooperate fully with one another in order to
minimize the inconvenience to Lessee resulting form any such relocation and the
parties shall execute the amendment of this lease.

28. RULES AND REGULATIONS: Lessee agrees to faithfully observe and comply with
the "Rules and Regulations," a copy of which is attached hereto and incorporated
herein by this reference as Exhibit "H", and all reasonable and
nondiscriminatory modifications thereof and additions thereto from time to
time put into effect by Lessor. Lessor will not be responsible to Lessee for
the violation or non-performance by any other lessee or occupant of the
Building of any of the Rules and Regulations.

29. MODIFICATION AND CURE RIGHTS OF LESSOR'S MORTGAGEES AND LESSORS: If, in
connection with Lessors obtaining or entering into any financing or ground lease
for any portion of the Building or the Development, the lender or ground lessor
request modifications to this Lease, lessee, within ten (10) days after request
therefor, agrees to execute an amendment to this Lease incorporating such
modifications, provided such modifications are reasonable an do not increase
the monetary obligations of Lessee under this Lease or adversely affect the
leasehold estate created by the Lease. In the event of any default on the part
of Lessor, Lessee will give notice by registered or certified mail to any
beneficiary of a deed of trust or mortgage covering the Premises or ground
lessor of Lessor whose address has been furnished to Lessee, and Lessee agrees
to offer such beneficiary, mortgagee or ground lessor a reasonable opportunity
to cure the default (including with respect to any such beneficiary or
mortgagee, time to obtain possession of the premises, subject to this Lease and
Lessee's rights hereunder, by power of sale or a judicial foreclose, if such
should prove necessary to effect a cure).

30. DEFINITION OF LESSOR: The term "Lessor", as used in this Lease, so far as
covenants or obligations on the part of Lessor are concerned, means and
includes only the owner or owners, at the time in question, of the fee title of
the Premises or the lessees under any ground lease, if any. In the event of any
transfer, assignment or other conveyance or transfers of any such title (other
than a transfer for security purposes only), Lessor herein named (and in case
of any subsequent transfers or conveyances, the then grantor) will be
automatically relieved from and after the date of such transfer, assignment or
conveyance of all liability as respects the performance of any covenants or
obligations on the part of Lessor contained in this Lease thereafter to be
performed, so long as the transferee assumes in writing all such covenants
and obligations of Lessor arising after the date of such transfer. Lessor and
Lessor's transferees and assignees have the absolute right to transfer all or
any portion of their respective title and interest in the Development, the
Building, the Premises and/or this Lease without the consent of Lessee, and
such transfer or subsequent transfer will not be deemed a violation on Lessor's
part of any of the terms and conditions of this Lease.

31. WAIVER: The waiver by either party of any breach of any term, covenant or
condition herein contained will not be deemed to be a waiver of any subsequent
breach of the same or any other term, covenant or condition herein




                                       18
<PAGE>   23
contained, nor will any custom or practice which may develop between the
parties in the administration of the terms hereof be deemed a waiver of or in
any way affect the right of either party to insist upon performance in strict
accordance with said terms. The subsequent acceptance of rent or any other
payment hereunder by Lessor will not be deemed to be a waiver of any preceding
breach by Lessee of any term, covenant or condition of this Lease, other than
the failure of Lessee to pay the particular rent so accepted, regardless of
Lessor's knowledge of such preceding breach at





                                      18A
<PAGE>   24


the time of acceptance of such rent. No acceptance by Lessor of a lesser sum
than the basic rent and additional rent or other sum then due will be deemed to
be other than on account of the earliest installment if such rent or other
amount due, nor will any endorsement or statement on any check or any letter
accompanying any check be deemed an accord and satisfaction, and Lessor may
accept such check or payment without prejudice to Lessor's right to recover the
balance of such installment or other amount or pursue any other remedy provided
in this Lease. The consent or approval of Lessor to or of any act by Lessee
requiring Lessor's consent or approval will not be deemed to waive or render
unnecessary Lessor's consent or approval to or of any subsequent similar acts by
Lessee.

32. PARKING: Lessee shall be entitled to use, in common with other lessees and
Lessor and its agents, the number of assigned and/or undesignated vehicle
parking spaces allocated to Lessee in Paragraph 1(n) subject to the terms and
conditions of this Paragraph 32 and the Rules and Regulations regarding parking,
and the parking contained in Exhibit "I" and "I" attached hereto; provided
however, that if the size of the Premises shall hereafter be reduced, whether
pursuant to an amendment of lease or any modification to this standard lease
form or otherwise, the number of parking spaces allocated to Lessee shall
automatically be reduced pro rata. Lessee's use of such parking spaces shall be
subject to payment by Lessee of such standard monthly parking rates, if any, as
may be charged from time to time to persons other than the officers and
employees of Lessor and its affiliates, and subject to such rules and
regulations as maybe reasonably established or altered from time to time by
Lessor or its manager of such parking facilities, provided that such rates do
not exceed fair market rates for comparable parking facilities in the basements
of comparable nearby office towers, all as reasonably determined by Lessor. At
Lessor's request, Lessee (or its designated employees with parking privileges)
shall enter into parking licenses or lease agreements or other arrangements then
in use by Lessor (or Lessor's operator of the parking facilities) with respect
to such monthly parking. Upon request, Lessee shall provide Lessor with the
license plate numbers of all vehicles used at the Facility by Lessee's
employees. In the event that, pursuant to any modification or amendment to this
standard form lease, Lessee is at any time given any right to the exclusive use
of any designated parking stalls or facilities, Lessor shall nevertheless have
the right from time to time to substitute other designated parking stalls or
facilities therefor, so long as such substitute stalls or facilities are, in
Lessor's judgment, reasonably comparable. If Lessee parks more vehicles in the
Facility's parking area than are permitted under this Section, Lessor shall have
the right, without limitation to Lessor's other remedies under this Lease, to
collect from Lessee a daily charge, to reasonably determined by Lessor, for
each such additional vehicle.

33. FORCE MAJEURE: If either Lessor or Lessee is delayed, hindered in or
prevented from the performance of any act required under this Lease by reason of
strikes, lock-outs, labor troubles, inability to procure standard materials,
failure of power, restrictive governmental laws, regulations or orders or
governmental action or inaction (including failure, refusal or delay in issuing
permits, approvals and/or authorizations which is not the result of the action
or inaction of the party claiming such delay), riots, civil unrest or
insurrection, war, fire, earthquake, flood or other natural disaster, unusual
and unforeseeable delay which results from an interruption or any public
utilities (e.g., electricity, gas, water, telephone) or other unusual and
unforeseeable delay not within the reasonable control of the party delayed in
performing work or doing acts required under the provisions of this Lease, then
performance work or doing acts required under the provisions of this Lease, then
performance of such act will be excused for the period of the delay and the
period for the performance of any such act the provisions of this Paragraph 33
will not operate to excuse Lessee from prompt payment of rent or any other
payments required under the provisions of the Lease.

34. SIGNS: Lessor will designate the location on the Premises, if any, for one
or more Lessee identification sign(s). Lessee agrees to have Lessor install and
maintain Lessee's identification sign(s) in such designated location in
accordance with this Paragraph 34 at LESSOR'S sole cost and expense. Lessee has
no right to install Lessee identification signs in any other location in, on or
about the Premises or the Development and will not display or erect any other
signs, displays or other advertising materials that are visible from the
exterior of the Building or from within the Building in any interior or exterior
common areas. The size, design, color and other physical aspects or any and all
permitted sign(s) will be subject to (i) Lessor's written approval prior to
installation, which approval may be withheld in Lessor's discretion, (ii) any
covenants, conditions or restrictions governing the Premises, and (iii) any
applicable municipal or governmental permits and approvals. Lessee will be
solely responsible for all costs for installation, maintenance, repair and
removal of any Lessee identification sign(s). If Lessee fails to remove Lessee's
sign(s) upon termination of this Lease and repair any damage caused by such
removal, Lessor may do so at Lessee's sole cost and expense. Lessee agrees to
reimburse Lessor for all costs incurred by Lessor to effect any installation,
maintenance or removal on Lessee's account, which amount will be deemed
additional rent, and may include, without limitation, all sums disbursed,
incurred or deposited by Lessor including Lessor's costs, expenses and actual
attorneys' fees with interest thereon at the Interest


                                       19
<PAGE>   25



Rate from the date of Lessor's demand until paid by Lessee. Any sign rights
granted to Lessee under this Lease are personal to Lessee and may not be
assigned, transferred or otherwise conveyed to any assignee or sublessee of
Lessee without Lessor's prior written consent, which consent Lessor may NOT
UNREASONABLY withhold in its sole and absolute discretion.

35. LIMITATION ON LIABILITY: In consideration of the benefits accruing
hereunder, Lessee on behalf of itself and all successors and assigns of Lessee
covenants and agrees that, in the event of any actual or alleged failure, breach
or default hereunder by Lessor: (a) Lessee's recourse against Lessor for
monetary damages will be limited to Lessor's interest in the Building including,
subject to the prior rights of any Mortgagee, Lessor's interest in the rents of
the Building and any insurance proceeds payable to Lessor; (b) except as may be
necessary to secure jurisdiction of the partnership, no partner may be necessary
to secure jurisdiction of the partnership, no partner of Lessor shall be sued or
named as a party in any suit or action and no service of process shall be made
against any partner of Lessor; (c) no partner of Lessor shall be required to
answer or otherwise plead to any service of process; (d) no judgment will be
taken against any partner of Lessor and any judgment taken against any partner
of Lessor may be vacated and set aside at any time after the fact; (e) no writ
of execution will be levied against the assets of any partner of Lessor; (f) the
obligations under this Lease do not constitute personal obligations of the
individual partners, directors, officers or shareholders of Lessor, and Lessee
shall no seek recourse against the individual partners, directors, officers of
shareholders of Lessor or any of their personal assets for satisfaction of any
liability in respect to this Lease; and (g) these covenants and agreements are
enforceable both by Lessor and also any partner of Lessor.

36. FINANCIAL STATEMENTS: Prior to the execution of this Lease by Lessor and at
any time during the Term of this Lease upon ten (10) days prior written notice
from Lessor, Lessee agrees to provide Lessor with a current financial statement
for Lessee and any guarantors of Lessee and financial statement for the two (2)
years prior to the current financial statement year for Lessee and any
guarantors of Lessee. Such statements are to be prepared in accordance with
generally accepted accounting principles and, if such is the normal practice of
Lessee, audited by an independent certified public accountant. LESSOR SHALL KEEP
SUCH STATEMENTS CONFIDENTIAL AND SHALL ONLY USE SUCH STATEMENT FOR PURPOSES
RELATED TO THIS LEASE OR THE FINANCING OF THE BUILDING OR PROJECT.

37. QUIET ENJOYMENT: Lessor covenants and agrees with Lessee that upon Lessee
paying the rent required under this Lease and paying all other charges and
performing all of the covenants and provisions on Lessee's part to be observed
and performed under this Lease, Lessee may peaceably and quietly have, hold and
enjoy the Premises in accordance with this Lease.

38. MISCELLANEOUS:

pursuant to the laws of the State OF CALIFORNIA, without giving effect to choice
of law principles thereunder.

(b) SUCCESSORS AND ASSIGNS: Except as otherwise provided in this Lease, all of

appraiser, accountants' and attorneys' fees and costs, incurred by the party
which prevails in such action, whether by final judgment or out of court
settlement, shall be paid by the other party, which obligation on the part of

(e) TIME: Time is of the essence with respect to the performance of every
provision of this Lease in which time of performance is a factor.

                       DEFINITION OF OPERATING EXPENSES


1. ITEMS INCLUDED IN OPERATING EXPENSES. The term "Operating Expenses" as used
in the Lease to which this Exhibit "E" is attached means: all costs and expenses
of operation and maintenance of the Building and the Common Areas (as such terms
are defined in the Lease), as determined by standard accounting practices,
calculated assuming the Building is ninety-five percent (95%) occupied,
including the following costs by way of illustration but not limitation, but
excluding those items specifically set forth in Paragraph 3 below: (a) Real
Property Taxes and Assessments (as defined in PARAGRAPH 2 below) and any taxes
or assessments imposed in lieu thereof; (b) any and all assessments imposed with
respect to the Building pursuant to any covenants, conditions and restrictions
affecting the Development, the Common Areas or the Building; (c) water and sewer
charges and the costs of electricity, heating, ventilating, air conditioning and
other utilities; (d) utilities surcharges and any other costs, levies or
assessments resulting from statutes or regulations promulgated by any government
or quasi-government authority in connection with the use, occupancy or
alteration of the Building or the premises or the parking facilities serving the

PARAGRAPH 19 of the Lease; (f) waste disposal and janitorial services; (g)

used in the management, operation and maintenance of the Building, (iii)
Building management office rental, supplies, equipment and related operating
expenses, and (iv) a management/administrative fee determined as a percentage of
the annual gross revenues of the Building exclusive of the proceeds of financing
or a sale of the Building and an administrative fee for the management of the
Development Common Area determined as a percentage of Development Common Area
Operating Expenses; (j) supplies, materials, equipment and tools including
rental of personal property used for maintenance; (k) repair and maintenance of
the elevators and the structural portions of the Building, including the
plumbing, heating, ventilating, air-conditioning and electrical systems
installed or furnished by Lessor; (l) maintenance, costs and upkeep of all
parking and Development Common areas; (m) depreciation on a straight line basis
and rental of personal property used in maintenance; (n) amortization on a
straight line basis over the useful life [together with interest at the Interest
Rate on the unamortized balance] of all capitalized expenditures which are: (i)
reasonably intended to produce a reduction in operating charges or energy
consumption; or (ii) required under any governmental law or regulation that was
not applicable to the Building at the time it was originally constructed; or
(iii) for replacement of any Building equipment needed to operate the Building
at the same quality levels as prior to the replacement; (o) costs and expenses
of gardening and landscaping; (p) maintenance of signs (other than signs of
Lessees of the Building); (q) personal property taxes levied on or attributable
to personal property used in connection with the Building or the Common Areas;
(r) reasonable accounting, audit, verification, legal and other consulting fees,
and (s) costs and expenses of repairs, resurfacing, repairing, maintenance,
painting, lighting, cleaning, refuse removal, security and similar items,
including appropriate reserves. When calculating Operating Expenses for
purposes of establishing Lessee's Base Operating Expense, Operating Expenses
shall not include Real Property Taxes and Assessments attributable to special
assessments, charges, costs, or fees or due to modifications or changes in
governmental laws or regulations including, but not limited to, the institution
of a split tax roll, and shall exclude market-wide labor-rate increases due to
extraordinary circumstances including, but not limited to, boycotts and strikes
and utility increases due to extraordinary circumstances including, but
not limited to, conservation surcharges, boycotts, embargos or other shortages.


2. REAL PROPERTY TAXES AND ASSESSMENTS. The term "Real Property Taxes and
Assessments", as used in this Exhibit "E," means: any form of assessment,
license fee, license tax, business license fee, commercial rental tax, levy
charge, improvement bond, tax or similar imposition imposed by any authority
having the direct power to tax, including any city, county, state or federal
government, or any school, agricultural, lighting, drainage or other improvement
or special assessment district thereof, as against any legal or equitable
interest of Lessor in the Premises, Building, Common Areas or the Development
(as such terms are defined in the Lease), adjusted to reflect an assumption that
the Building is fully assessed for real property tax purposes as a completed
building ready for occupancy, including the following by way of illustration but
not limitation: (a) any tax on Lessor's "right" to rent or "right" to other
income from the Premises or as against Lessor's business of leasing the
Premises; (b) any assessment, tax, fee, levy or charge in substitution,
partially or totally, of any assessment, tax, fee, levy or charge previously
included within the definition of real property tax, it being acknowledged by
Lessee and Lessor that Proposition 13 was adopted by the voters of the State of
California in the June,


                                       28

<PAGE>   34


1978 election and that assessments, taxes, fees, levies and charges may be
imposed by governmental agencies for such services as fire protection, street,
sidewalk and road maintenance, refuse removal and for other governmental
services formerly provided without charge to property owners or occupants. It is
the intention of Lessee and Lessor that all such new and increased assessments,
taxes, fees, levies and charges be included within the definition of "real
property taxes" for the purposes of this Lease; (c) any assessment, tax, fee,
levy or charge allocable to or measured by the area of the premises or other
premises in the Building or the rent payable by Lessee hereunder or other
lessees of the Building, including, without limitation, any gross receipts tax
or excise tax levied by state, city or federal government, or any political
subdivision thereof, with respect to the receipt of such rent, or upon or with
respect to the possession, leasing, operation, management, maintenance,
alteration, repairs, use or occupancy by Lessee of the Premises, or any portion
thereof but not on Lessor's other operations; (d) any assessment, tax, fee, levy
or charge upon this transaction or any document to which Lessee is a party,
creating or transferring an interest or an estate in the Premises; and/or (e)
any assessment, tax, fee, levy or charge by any governmental agency related to
any transportation plan, fund or system (including assessment districts)
instituted within the geographic area of which the Building is a part.

Notwithstanding the foregoing, if at any time after the Commencement Date, the
amount of Real Property Taxes and Assessments decreases, then for purposes of
all subsequent Lease Years, including the Lease Year in which such decrease in
Real Property Taxes and Assessments occurs, Lessee's Base Operating Expense
shall be decreased by an amount equal to such decrease in Real Property Taxes
and Assessments.



      3. ITEMS EXCLUDED FROM OPERATING EXPENSES. Notwithstanding the provisions
         of PARAGRAPHS 1 AND 2 above to the contrary, "Operating Expenses" will
         not include: (a) Lessor's federal or state OR NET income, franchisee,
         inheritance TRANSFER, GIFT, or estate taxes; (b) any ground lease
         rental; (c) costs incurred by Lessor for the repair of damage to the

         specifically provided herein, and except on materials, tools, supplies
         and vendor-type equipment purchased by Lessor to enable Lessor to
         supply services Lessor might otherwise contract for with a third party,
         where such depreciation, amortization and interest payments would

         services, all as determined in accordance with standard accounting
         practices; (e) brokerage commissions, finders' fees, attorneys' fees,
         space planning costs and other costs incurred by Lessor in leasing or
         attempting to lease space in the Building; (f) costs of a capital
         nature, including, without limitation, capital improvements, capital
         replacements, capital repairs, capital equipment and capital tools, all
         as determined in accordance with standard accounting practices;
         provided, however, the capital expenditures set forth in Subparagraph
         1(n) above will in any event be included in the definition of Operating
         Expenses; (g) interest, principal, points and fees on debt or
         amortization on any mortgage, deed of trust or other debt encumbering
         the Building or the Development; (h) costs, including permit, license
         and inspection costs, incurred with respect to the installation of

         and expenses incurred in connection with negotiations or disputes with

         attorneys' fees and other costs and expenses incurred in connection
         with negotiations, disputes or claims relating to items of Operating

         Lessor under the Lease; (j) except for the administrative/management
         fees described in SUBPARAGRAPH 1(i) above, costs of Lessor's general

                                   EXHIBIT "F"


                      STANDARDS FOR UTILITIES AND SERVICES


The following standard for utilities and services are in effect. Lessor reserves
the right to adopt nondiscriminatory modifications and additions hereto.

Subject to the terms and conditions of the Lease and provided Lessee remains in
occupancy of the Premises, Lessor will provide or make available the following
utilities and services:

1. Provide non-attended automatic elevator facilities Monday through Friday,
except holidays, from 6:00 a.m. to 10:00 p.m., and have one elevator available
for Lessee's use at all other times.

2. On Monday through Friday, except holidays from 6:00 a.m. to 12:00 a.m. (and
other times at a reasonable hourly additional charge fixed by Lessor), ventilate
the Premises and furnish air conditioning or heating on such days and hours,
when in the reasonable judgment of Lessor it may be required for the comfortable
occupancy of the Premises. The air conditioning system achieves maximum cooling
when the window coverings are extended to the full length of the window opening
and adjusted to a 45 degree angle upwards. Lessor will not be responsible for
room temperatures if Lessee does not keep all window coverings in the Premises
extended to the full length of the window opening and - adjusted to a 45 degree
angle upwards whenever the system is in operation. Lessee agrees to cooperate
fully at all times with Lessor, and to abide by all reasonable regulations and
requirements which Lessor may prescribe for the proper function and protection
of said air conditioning system. Lessee agrees not to connect any apparatus,
device, conduit or pipe to the chilled and hot water air conditioning supply
lines of the Building. Lessee further agrees that neither Lessee nor its
servants, employees, agents, visitors, licensees or contractors shall at any
time enter the mechanical installations or facilities of the Building or the
Development or adjust, tamper with, touch or otherwise in any manner affect said
installations or facilities. The cost of maintenance and service calls to adjust
and regulate the air conditioning system will be charged to Lessee if the need
for maintenance work results from either Lessee's adjustment of room thermostats
or Lessee's failure to comply with its obligations under this Exhibit, including
keeping window coverings extended to the full length of the window opening and
adjusted to a 45 degree angle upwards. Such work will be charged at hourly rates
equal to then-current journeyman's wages for air conditioning mechanics.

3. Lessor will make available to the Premises, 24 hours per day, seven days a
week, electric current as required by the Building standard office lighting and
fractional horsepower office business machines including copiers, personal
computer and word processing equipment in an amount not to exceed six (6) watts
per square foot per normal business day. Lessee agrees, should its electrical
installation or electrical consumption be in excess of the aforesaid quantity or
extend beyond normal business hours, to reimburse Lessor monthly for the
measured consumption at the average cost per kilowatt hour charged to the
building during the period. If a separate meter is not installed at Lessee's
cost, such excess cost will be established by an estimate agreed upon by Lessor
and Lessee, and if the parties fail to agree, such cost will be established by
an independent licensed engineer selected in Lessors reasonable discretion,
whose fee shall be shared equally be Lessor and Tenet. Lessee agrees not to use
any apparatus or device in, upon or about the Premises (other than standard
office business machines, personal computers and work processing equipment)
which may in any way increase the amount of such services usually furnished or
supplied to said Premises, and Lessee further agrees not to connect any
apparatus or device with wires, conduits or pipes, or other means by which such
services are supplied, for the purpose of using additional or unusual amounts of
such services without the written consent of Lessor. Should Lessee use the same
to excess, the refusal on part of Lessee to pay upon demand of Lessor the amount
established by Lessor for such excess charge will constitute a breach of the
obligation to pay rent under this Lease and will entitle Lessor to the rights
therein granted for such breach. Lessee's use of electric current will never
exceed the capacity of the feeders to the Building, or the risers or wiring
installation and Lessees will not install or use or permit the installation of
use of any computer or electronic data processing equipment in the Premises
(except standard office business machines, personal computers and word
processing equipment) without the prior written consent of Lessor.

4. Water will be available in public and for drinking and lavatory purposes
only, but if Lessee requires, uses or consumes water for any purpose in addition
to ordinary drinking and lavatory purposes, of which fact Lessee constitutes

                                       30

<PAGE>   36



Lessor to be the sole judge, Lessor may install a water meter and thereby
measure Lessee's water consumption for all purposes. Lessee agrees to pay Lessor
for the cost of the meter and the cost of the installation thereof and
throughout the duration of Lessee's occupancy Lessee will keep said meter and
installation equipment in good working order and repair at Lessee's own cost and
expense, in default of which Lessor may cause such meter and equipment to be
replaced or repaired and collect the cost thereof from Lessee. Lessee agrees to
pay for water consumed, as shown on such meter, as and when bills and rendered,
and on default in making such payment, Lessor may pay such charges and collect
the same from Lessee. Any such costs or expenses incurred, or payments made by
Lessor for any of the reasons or purposes hereinabove stated will be deemed to
be additional rent payable by Lessee and collectible by Lessor as such.

5. Lessor will provide janitor service to the Premises, provided the same are
used exclusively as offices, and are kept reasonably in order by Lessee, and
unless otherwise agreed to by Lessor and Lessee no one other than persons
approved by Lessor shall be permitted to enter the Premises for such purposes.
If the Premises are not used exclusively as offices, they will be kept clean and
in order by Lessee, at Lessee's expense, and to the satisfaction of Lessor, and
by persons approved by Lessor. Lessee agrees to pay to Lessor the cost of
removal of any of Lessee's refuse and rubbish to the extend that the same
exceeds the refuse and rubbish usually attendant upon the use of the Premises as
offices.

6. Lessor reserves the right to stop service of the elevator, plumbing,
ventilation, air conditioning and electrical systems, when necessary, by reason
of accident or emergency or for repairs, alterations or improvements, when in
the judgment of Lessor such actions are desirable or necessary to be made, until
said repairs, alterations or improvements shall have been completed, and Lessor
will have no responsibility or liability for failure to supply elevator
facilities, plumbing, ventilating, air conditioning or electric service, when
prevented from so doing by strike or accident or by any cause beyond Lessor's
reasonable control, or by laws, rules orders, ordinances, directions,
regulations or by reason of the requirements of any federal, state, county or
municipal authority or failure of gas, oil or other suitable fuel supply or
inability by exercise of reasonable diligence to obtain gas, oil or other
suitable fuel supply. It is expressly understood and agreed that any covenants
on Lessor's part to furnish any services pursuant to any of the terms,
covenants, conditions, provisions or agreements of this Lease, or to perform any
act or thing for the benefit of Lessee, will not be deemed breached if Lessor is
unable to furnish or perform the same by virtue of a strike of labor trouble or
any other cause whatsoever beyond Lessor's control.

                              RULES AND REGULATIONS


A. GENERAL RULES AND REGULATIONS. The following rules and regulations govern the
use of the Building and the Development Common Areas. Lessee will be bound by
such rules and regulations and agrees to cause Lessee's Authorized users, its
employees, sublessees, assignees, contractors, suppliers, customers and invitees
to observe the same.

1. Except as specifically provided in the Lease to which these Rules and
Regulations are attached, no sign, placard, picture, advertisement, name or
notice maybe installed or displayed on any part of the outside or inside of the
Building or the Development without the prior written consent of Lessor. Lessor
will have the right to remove, at Lessees expense and without notice, any sign
installed or displayed in violation of this rule. All approved signs or
lettering on doors and walls are to be printed, painted, affixed or inscribed at
the expense of Lessee and under the direction of Lessor by a person or company
designated or approved by Lessor.

2. If Lessor objects in writing to any curtains, blinds, shades, screens or
hanging plants or other similar objects attached to or used in connection with
any window or door of the Premises, or placed on any windowsill, which is
visible from the exterior of the Premises, Lessee will immediately discontinued
such use. Lessee agrees not to place anything against or near glass partitions
of doors or windows which may appear unsightly from outside the Premises
including from within any interior common areas.

3. Lessee will not obstruct any sidewalks, halls, passages, exits, entrances,
elevators, escalators, or stairways of the Development. The halls, passages,
exits, entrances, elevators and stairways are not open to the general public,
but are open, subject to reasonable regulation, to Lessee's business invitees.
Lessor will in all cases retain the right to control and prevent access thereto
of all persons whose presence in the reasonable judgment of Lessor would be
prejudicial of the safety, character, reputation and interest of the Development
and its lessees, provided that nothing herein contained will be construed to
prevent such access to persons with whom any lessee normally deals in the
ordinary course of its business, unless such persons are engaged in illegal or
unlawful activities. No lessee and no employee or invitee of any lessee will go
on the roof of the Building.

4. Lessee will not obtain for use on the Premises ice, drinking water, food,
food vendors, beverage, towel or other similar services or accept barbering or
bootblacking service upon the Premises, except at such reasonable hours and
under such reasonable regulations as maybe fixed by Lessor. Lessor expressly
reserves the right to absolutely prohibit solicitation, canvassing, distribution
of handbills or any other written material, peddling, sales and displays of
products, goods and wares in all portions of the Development except as may be
expressly permitted under the Lease. Lessor reserves the right to restrict and
regulate the use of the common areas of the Development and Building by invitees
of lessees providing services to lessees on a periodic or daily basis including
food and beverage vendors. Such restrictions may include limitations on time,
place, manner and duration of access to a lessee's premises for such purposes.
Without limiting the foregoing, Lessor may require that such parties use service
elevators, halls, passageways and stairways for such purposes to preserve access
within the Building for lessees and the general public.

5. Lessor reserves the right to require lessee to periodically provide Lessor
with a written list of any and all business invitees which periodically or
regularly provide goods and services touch lessees at the premises. Lessor
reserves the right to preclude all vendors from entering or conducting business
within the Building and the Development if such vendors are not listed on a
lessee's list of requested vendors.

6. Lessor reserves the right to exclude from the Building between the hours of
6:00 p.m., and 8:00 a.m. the following business day, or such other hours as may
be established from time to time by Lessor, and on Sundays and legal holidays,
any person unless that person is known to the person or employee in charge of
the Building or has a pass or is properly identified. Lessee will be responsible
for all persons for whom it requests passes and will be liable to Lessor for all
acts of such persons. Lessor will not be liable for damages for any error with
regard to the admission to or exclusion from



                                       37
<PAGE>   43

the Building of any person. Lessor reserves the right to prevent access to the
Building in case of invasion, mob, riot, public excitement or other commotion by
closing the doors or by other appropriate action.

7. The directory of the Building or the Development will be provided exclusively
for the display of the name and location of lessees only and Lessor reserves the
right to exclude any other names therefrom.

8. All cleaning and janitorial services for the Development and the Premises
will be provided exclusively through Lessor, and except with the written consent
of Lessor, no person or persons other than those approved by Lessor will be
employed by Lessee or permitted to enter the Development for the purpose of
cleaning the same. Lessee will not cause any unnecessary labor by carelessness
or indifference to the good order and cleanliness of the Premises.

9. Lessor will furnish Lessee, free of charge, with two keys to each door lock
in the Premises. Lessor may make a reasonable charge for any additional keys.
Lessee shall not make or have made additional keys, and Lessee shall not alter
any lock or install any new additional lock or bolt on any door of the Premises.
Lessee, upon the termination of its tenancy, will deliver to Lessor the keys to
all doors which have been furnished to Lessee, and in the event of loss of any
keys so furnished, will pay Lessor therefor.

10. If Lessee requires telegraphic, telephonic, burglar alarm, satellite dishes,
antennae or similar services, it will first obtain Lessor's approval, and comply
with, Lessor's reasonable rules and requirements applicable to such services,
which may include separate licensing by, and fees paid to, Lessor.

11. Freight elevator(s) will be available for use by all lessees in the
Building, subject to such reasonable scheduling as Lessor, in its discretion,
deems appropriate. No equipment, materials, furniture, packages, supplies,
merchandise or other property will be received in the Building or carried in the
elevators except between such hours and in such elevators as may be designated
by Lessor. Lessee's initial move in and subsequent deliveries of bulky times,
such as furniture, safes and similar items will, unless others agreed in writing
by Lessor, be made during the hours of 6:00 p.m. to 6:00 a.m. or on Saturday or
Sunday. Deliveries during normal office hours shall be limited to normal office
supplies and other small items. No deliveries will be made which impede or
interfere with other lessees or the operation of the Building.

12. Lessee will not place a load upon any floor of the Premises which exceeds
the load per square foot which such floor was designed to carry and which is
allowed by law. Lessor will have the right to reasonably prescribe the weight,
size and position of all safes, heavy equipment, files, materials, furniture or
other property brought into the Building. Heavy objects will, if considered
necessary by Lessor, stand on such platforms as determined by Lessor to be
necessary to properly distribute the weight, which platforms will be provided at
Lessee's expense. Business machines and mechanical equipment belonging to
Lessee, which cause noise or vibration that may be transmitted to the structure
of the Building or to any space therein to such a degree as to be objectionable
to any lessees in the Building or Lessor, are to be placed and maintained by

full and faithful performance by Licensee of all the terms, covenants and
conditions of the License to be performed by Licensee. If License defaults with

or any part of this security deposit for the payment of any rent or other sum
due hereunder or to compensate Licensor for any loss or damage Licensor suffers
by reason of Licensee's default, and said security deposit shall not be
considered as liquidated damages. Licensee waives all claims to interest on
such deposit. In the event of termination of Licensor's interest in this
License, Licensor shall transfer the deposit to its successor in interest.
