                               PROSPECTUS SUMMARY


     You should read this summary together with the more detailed information,
including our consolidated financial statements and the related notes, appearing
elsewhere in this prospectus.


                               OTG SOFTWARE, INC.


     We are a leading provider of online data storage management and data access
software solutions. Our software enables enterprises to move, store, manage and
access data quickly and efficiently over a variety of network architectures,
including the Web and storage area networks. Our software supports many
different types of storage devices, is easy to install and use, and can manage
storage systems ranging in size from a single storage device to an
enterprise-wide network storage system.



     The growth of data-intensive computing functions such as e-commerce,
e-mail, multimedia applications, complex enterprise computer applications and
the conversion from paper to electronic storage has fueled rapid growth in the
amount of data stored by enterprises. This growth has increased the demand for
data storage management software. International Data Corporation, an independent
information technology research firm referred to as IDC, estimates that the
overall market for data protection and management software will grow from $3.5
billion in 1998 to $6.7 billion in 2003.



     Traditionally, enterprises have focused on protecting data by backing it up
on secondary storage devices. This process restricts direct access to data by
users and software applications and results in repetitively backing up the same
data. One response to these limitations has been the emergence of storage area
networks. A storage area network is a network of servers and data storage
devices that are interconnected at high speeds, allowing network resources to be
located at remote and diverse locations. IDC estimates that the overall storage
area network market will grow from $3.4 billion in 1999 to more than $13.8
billion in 2003. Storage area networks are designed to store more data more
quickly but not to make the data storage and access process more efficient.



     Our solutions enhance the performance of both traditional storage and
back-up methods and storage area networks by:


     - automatically applying policies that determine whether, or for how long,
       data should be stored;


     - providing efficient transfer of data to and from storage devices
       throughout networks, including storage area networks;


     - providing a detailed index of stored data;

     - enabling rapid and easy retrieval of stored data selected by users and
       software applications;

     - maximizing the effective capacity of existing storage devices; and

     - providing secure Web access to stored data.


     We market our products primarily through more than 13 original equipment
manufacturers and more than 235 domestic and international value-added resellers
and distributors, as well as through our direct sales force. We have licensed
our products to more than 6,000 corporations, government agencies and other
organizations across a broad spectrum of industries. Our customers include
American Airlines, Citicorp, Dow Chemical, Mayo Clinic, Nabisco, the National
Association of Securities Dealers, Nortel Networks, PSINet, the University of
Miami and the U.S. Department of Defense.



     We have a history of losses and a significant accumulated deficit. For the
year ended December 31, 1999, we had a pro forma net loss of $1.5 million. As of
December 31, 1999, we had an accumulated deficit of $22.4 million. We operate in
a highly competitive market characterized by rapid technological change. We are
controlled by Mr. Kay, our chairman, president and chief executive officer, who
beneficially owns 61.5% of our common stock outstanding prior to this offering
and will beneficially own 51.5% of our outstanding common stock after this
offering.

                      SUMMARY CONSOLIDATED FINANCIAL DATA



     The following table is a summary of the financial data for our business.
You should read this information together with the consolidated financial
statements and the related notes appearing at the end of this prospectus and the
information under "Management's Discussion and Analysis of Financial Condition
and Results of Operations." The pro forma statement of operations data reflects
federal and state income taxes based on applicable tax rates as if we had not
elected S corporation status for the periods indicated. See note 1 to our
consolidated financial statements appearing elsewhere in this prospectus for
information regarding shares used in computing pro forma net income (loss) per
share -- basic and diluted. The pro forma balance sheet data gives effect to the
automatic conversion of all outstanding convertible notes issued by us on the
closing of this offering and the distribution at the closing of $1.6 million,
reflecting estimated S corporation tax liabilities of the existing stockholders.
The pro forma as adjusted balance sheet data also reflects the sale of the
common stock offered by us, after deducting estimated underwriting discounts and
estimated offering expenses payable by us, and our use of a portion of the
proceeds to repay debt.

                                  RISK FACTORS

     You should carefully consider the following risk factors and all other
information contained in this prospectus before investing in our common stock.
Investing in our common stock involves a high degree of risk. Any of the
following factors could harm our business and materially adversely affect our
future operating results and could result in a partial or complete loss of your
investment.

RISKS RELATED TO OUR BUSINESS

WE MAY NOT BE ABLE TO SUSTAIN OUR CURRENT REVENUE GROWTH RATES, WHICH COULD
CAUSE OUR STOCK PRICE TO DECLINE


     Although our revenues have grown rapidly in recent years, we may not be
able to maintain this rate of revenue growth because of the difficulty of
maintaining high percentage increases as our base of revenue increases. In
addition, growing competition, lower-than-expected market acceptance of Windows
NT and the expected next version of Windows NT, known as Windows 2000, or the
failure of the market for storage area networks to develop, could also affect
our revenue growth. Our inability to maintain our rate of revenue growth could
cause our stock price to decline.


OUR OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY AND MAY CAUSE OUR STOCK PRICE
TO DECLINE

     Fluctuations in our operating results are likely to affect our stock price
in a manner that may be unrelated to our long-term operating performance.

     Our revenues in any quarter will depend substantially on orders we receive
and ship in that quarter. In addition, we typically receive a significant
portion of orders during the last month of each quarter, and we cannot predict
whether those orders will be placed, fulfilled and shipped in that period. If we
have lower revenues than we expect, we probably will not be able to reduce our
operating expenses in time to compensate for any revenue shortfall. Therefore,
any significant shortfall in revenues or delay of customer orders could have an
immediate adverse effect on our operating results in that quarter.

     Our operating results have fluctuated in the past, and they are likely to
fluctuate significantly in the future. Quarterly comparisons of our financial
results are not necessarily meaningful and you should not rely on them as an
indication of our future performance. Factors that could affect our operating
results include:

     - the unpredictability of the timing and level of sales through our
       indirect sales channels;

     - the timing and magnitude of large orders;

     - changes in the mix of our sales, including the mix between higher margin
       software licenses and lower margin services;

     - the timing and amount of our marketing, sales and product development
       expenses;

     - the cost and time required to develop new software products;

     - the introduction, timing and market acceptance of new products introduced
       by us or our competitors;

     - changes in data storage and networking technology or the introduction of
       new operating system upgrades, which could require us to modify our
       products or develop new products;

     - the growth rate of Windows NT;

     - the rate of adoption of Windows 2000;

                                        6
<PAGE>   10


     - the rate of adoption of storage area networks;


     - pricing policies and distribution terms; and

     - the timing and size of acquisitions.

     In addition, our efforts to expand our software product suite, sales and
marketing activities, direct and indirect distribution channels and maintenance
and technical support functions and to pursue strategic relationships or
acquisitions may not succeed or may prove more expensive than we anticipate. As
a result, we cannot predict our future operating results with any degree of
certainty and our operating results may vary significantly from quarter to
quarter.

OUR BUSINESS DEPENDS ON THE ACCEPTANCE OF WINDOWS NT AND WINDOWS 2000 TO RUN
COMPUTER NETWORKS, AND A DECREASE IN THEIR RATES OF ACCEPTANCE COULD CAUSE OUR
REVENUES TO DECLINE

     For the foreseeable future, we expect a substantial majority of our
revenues to continue to come from sales of our Windows NT-based data storage
software products. As a result, we depend on the growing use of Windows NT for
computer networks. If the deployment of Windows NT does not increase as we
anticipate, or if it decreases, our revenues could decline. In addition, if
users do not accept Windows 2000, or if there is a wide acceptance of other
existing or new operating systems, our business would suffer.

     Windows 2000 may not gain market acceptance if its expected commercial
release date is delayed. In addition, users of previous versions of Windows NT
may decide to migrate to another operating system due to these delays or
improved functionality of another operating system. We have expended significant
resources on the development of Windows 2000-compatible versions of our product
suite and our future success depends upon sales of this product suite. If users
of Windows 2000 networks do not widely adopt and purchase our products, our
revenue and business will suffer. Furthermore, if we fail to introduce Windows
2000-compatible versions of our product suite within a short time after the
commercial release of Windows 2000, the delay may cause customers to forego
purchases of our products and instead purchase those of our competitors.


OUR SUCCESS DEPENDS UPON THE DEVELOPMENT OF THE EMERGING MARKET FOR STORAGE AREA
NETWORKS, AND IF THIS MARKET FAILS TO DEVELOP, OR DEVELOPS MORE SLOWLY THAN WE
ANTICIPATE, OR IF OUR PRODUCTS ARE NOT WIDELY ACCEPTED IN THIS MARKET, OUR
BUSINESS WILL SUFFER



     Our future growth and profitability will depend upon the widespread
acceptance of storage area networks as an enterprise-wide data storage method
and the acceptance of our products for use in such networks. Accordingly,
widespread adoption of storage area networks is critical to our future success.
The market for storage area networks has only recently begun to develop and
evolve. Because this market is new, it is difficult to predict its potential
size or growth rate. Potential customers that have invested substantial
resources in their existing data storage management systems may be reluctant or
slow to adopt a new approach like storage area networks. Our success in
generating revenues in this emerging market will depend, among other things, on
our ability to educate potential original equipment manufacturers and system
integrators, as well as potential end-users, about the benefits of storage area
networks and our data storage management solutions when deployed in the storage
area network environment. Furthermore, although we are attempting to position
our products as a standard for data storage management on storage area networks,
if we are unsuccessful in doing so, competing standards may emerge that will be
preferred by original equipment manufacturers, systems integrators or end-users.


                                        7
<PAGE>   11

WE HAVE EXPERIENCED SIGNIFICANT GROWTH IN OUR BUSINESS AND OUR FAILURE TO MANAGE
THIS GROWTH OR ANY FUTURE GROWTH COULD HARM OUR BUSINESS


     We continue to increase the scope of our operations and have grown our
headcount substantially. As of June 30, 1998, we had a total of 104 employees,
as of December 31, 1998 we had a total of 144 employees and as of December 31,
1999 we had a total of 172 employees. Our productivity and the quality of our
products may be adversely affected if we do not integrate and train our new
employees quickly and effectively. We also cannot be sure that our revenues will
continue to grow at a rate sufficient to absorb the costs associated with a
larger overall headcount.


     Our future success and our ability to sustain our revenue growth also
depend upon the continued service of our executive officers and other key sales
and research and development personnel. The loss of any of our executive
officers or key employees, especially Richard A. Kay, F. William Caple and
Ronald W. Kaiser, could adversely affect our business and slow our product
development processes. Although we have employment agreements with these
executives, these agreements do not obligate them to remain employed by us. We
do not have key person life insurance policies covering any of our employees.
Furthermore, we must continue to hire large numbers of highly qualified
individuals. Competition for these individuals is intense, and we may not be
able to attract, assimilate or retain additional highly qualified personnel in
the future.

     To achieve our business objectives, we may recruit and employ skilled
technical professionals from other countries to work in the United States.
Limitations imposed by federal immigration laws and the availability of visas
could compromise our ability to attract necessary qualified personnel. This may
have a negative effect on our business and future operating results.

OUR REVENUES PRIMARILY DEPEND ON SALES OF LICENSES FOR ONE PRODUCT LINE, OUR
XTENDERSOLUTIONS PRODUCT SUITE, AND A DECLINE IN SALES OF LICENSES FOR THIS
PRODUCT SUITE COULD CAUSE OUR REVENUES TO FALL


     We have derived the substantial majority of our revenue from the sale of
our XtenderSolutions product suite. During 1997, 1998 and 1999, sales of our
XtenderSolutions products accounted for approximately 72%, 70% and 72% of our
total revenues, respectively. We expect that these products will continue to
account for a large portion of our revenues for the foreseeable future.
Accordingly, our business and future operating results depend on the continued
market acceptance of our XtenderSolutions products and future enhancements to
these products. Any factors adversely affecting the pricing of, demand for or
market acceptance of our XtenderSolutions products, including competition or
technological change, could cause our revenues to decline and our business and
future operating results to suffer.



OUR MULTIPLE DISTRIBUTION CHANNELS ARE SUBJECT TO MANY RISKS THAT COULD
ADVERSELY AFFECT OUR SALES


     Direct sales.  We have a growing direct sales force to sell our products,
especially to large customers. Direct sales involve a number of risks,
including:

     - longer sales cycles, typically three to six months;

     - our need to hire, train, retain and motivate our sales force; and

     - the length of time it takes our new sales representatives to begin
       generating sales.


     Indirect sales.  We expect that a significant portion of our revenues will
continue to come from indirect sales. These include sales to original equipment
manufacturers that incorporate our data storage management software into systems
they sell. We also expect future revenues from distributors and value-added
resellers that sell our software, often bundled with their own software or
services. We have no control over the shipping dates or volumes of systems our
original equipment


                                        8
<PAGE>   12


manufacturers, value-added resellers or distributors ship, and they have no
obligation to ship systems incorporating our software. They generally have no
minimum sales requirements and can terminate their relationship with us on short
notice. We develop customized versions of our products for some of our original
equipment manufacturers to be included in their systems software and other
products. Developing products for these original equipment manufacturers causes
us to divert resources from other activities which are also important to our
business. If these versions do not result in substantial revenues, our business
and financial results could be adversely affected.



OUR ORIGINAL EQUIPMENT MANUFACTURERS COULD CHOOSE TO COMPETE WITH US OR WITH
EACH OTHER, WHICH COULD HARM OUR BUSINESS



     Our original equipment manufacturers, value-added resellers and
distributors could choose to develop their own data storage management products
and incorporate those products into their systems or product offerings in lieu
of our products. In addition, the original equipment manufacturers that we do
business with may compete with one another. To the extent that one of our
original equipment manufacturer customers views the products we have developed
for another original equipment manufacturer as competitive, it may decide to
stop doing business with us, which could harm our business.



OVERLAPPING SALES EFFORTS MAY LEAD TO INEFFICIENCIES AND MAY ADVERSELY AFFECT
OUR RELATIONSHIPS WITH THOSE WHO SELL OUR PRODUCTS



     Our original equipment manufacturers, value-added resellers, distributors
and direct sales force might target the same sales opportunities, which could
lead to an inefficient allocation of sales resources. This would result in us
marketing similar products to the same end-users. These overlapping sales
efforts could also adversely affect our relationships with our original
equipment manufacturers, value-added resellers, distributors and other sales
channels and result in them being less willing to market our products
aggressively.



THE MARKET FOR OUTSOURCED DATA STORAGE SOLUTIONS OVER THE WEB IS NEW AND
EVOLVING, AND IF THIS MARKET FAILS TO DEVELOP, OUR BUSINESS COULD SUFFER



     Part of our strategy is to offer outsourced data storage solutions to
customers over the Web. In this business model, customers who wish to reduce
their in-house hardware and maintenance costs would pay us or a third party
using our products to provide metered or leased data storage capacity and
management. If this business model does not gain acceptance among potential
customers, we will not be able to implement this strategy successfully. The
market for electronic outsourced data storage solutions has only recently begun
to emerge and we cannot be sure that it will develop or grow. Among other
things, the development of this market could be limited by:


     - concerns over the reliability and security of the Web, especially as a
       means of moving data that is critical to the customer's business; and

     - customer reluctance to cede control over the hardware and network
       infrastructure used to store important data and to rely on systems
       provided by a third party.


We do not currently provide outsourced data storage services and do not have any
significant experience in the market for these services. We are expending
significant resources to develop products for this market, and if this market
fails to develop, or if we are unable to enter it successfully, we will not
realize any return on this investment, and our business may suffer.


                                        9
<PAGE>   13

IF WE ENCOUNTER SYSTEM FAILURES OR OTHER DIFFICULTIES IN PROVIDING OUTSOURCED
DATA STORAGE SERVICES, WE COULD BE EXPOSED TO LIABILITY AND OUR REPUTATION COULD
SUFFER


     We will depend upon a hardware and networking infrastructure to deliver
outsourced data storage capacity to our customers. If this infrastructure fails,
or customers otherwise experience difficulties or delays in retrieving data, we
could face liability claims from them and our reputation could be damaged. We
currently expect that we will not develop the hardware and networking
infrastructure ourselves, but rather will contract with third parties, such as
Internet service providers and application service providers, to supply these
components on our behalf. For this reason, we will be dependent on the
performance of the systems deployed and maintained by these parties, whom we
will not control. In some cases, we might contract directly with the customer to
provide the outsourced services; in other cases, we might act as a reseller for
application service providers, Internet service providers or others. In either
case, we would expect to include contractual provisions limiting our liability
to the customer for system failures and delays, but we cannot be sure that these
limits will be enforceable or will be sufficient to shield us from liability. We
also expect that we would carry liability insurance to cover problems of this
nature, but we cannot guarantee that insurance will be available or that the
amounts of our coverage will be sufficient to cover all potential claims.



OTHER COMPANIES HAVE DEVELOPED OR MAY CHOOSE TO DEVELOP COMPETING PRODUCTS AND
POTENTIAL CUSTOMERS FOR OUR PRODUCTS MAY CHOOSE TO DEVELOP INTERNAL DATA STORAGE
MANAGEMENT CAPABILITIES OR SATISFY THEIR NEEDS WITH A TRADITIONAL DATA BACK-UP
SOLUTION, ANY OF WHICH COULD CAUSE OUR REVENUES AND OUR BUSINESS TO SUFFER



     We face a variety of competitors that offer products with some of our
products' features. Some potential customers may elect to internally develop
capabilities similar to those provided by our products rather than buying them
from us or another outside vendor. Although our products generally enhance
traditional data back-up capabilities offered by companies such as Veritas,
Legato Systems, Computer Associates and IBM, our products may compete against
traditional back-up solutions when a potential customer seeks to address its
storage needs with only a data back-up solution. Furthermore, Veritas has
recently begun to offer a Windows NT-based product that competes with
DiskXtender. If potential customers choose to develop their own capabilities,
choose a traditional data back-up solution or purchase a competing product, our
revenues and business will suffer.



     In addition, Microsoft could develop competing products. Windows 2000 will
include basic data storage management capabilities. Microsoft could compete with
us by enhancing and expanding these capabilities to offer an integrated storage
management capability within their basic operating system. This would reduce or
eliminate the need to purchase our products, which would cause our revenues and
business to suffer.



OUR PRODUCTS MUST REMAIN COMPATIBLE WITH OPERATING SYSTEM SOFTWARE, NETWORK
HARDWARE AND SOFTWARE CONFIGURATIONS, WHICH ARE CURRENTLY UNDERGOING, AND WILL
LIKELY CONTINUE TO UNDERGO, SIGNIFICANT CHANGE THAT COULD RENDER OUR PRODUCTS
OBSOLETE



     The market for our data storage management software is characterized by
rapid technological change, frequent new product introductions and enhancements,
uncertain product life cycles, changes in customer demands and evolving industry
standards. Our products could be rendered obsolete if products based on new
technologies are introduced or new industry standards emerge. We have expended
significant resources to allow our products to take advantage of the release of
Windows 2000 and to prepare our products for the emergence of storage area
networks, and we expect to continue to do so. If Windows 2000 and storage area
networks are not widely adopted, our business and future operating results will
suffer.


                                       10
<PAGE>   14


     As the emergence of storage area networks demonstrates, the computing
environments in which our products must operate are complex and change rapidly.
As a result, we cannot accurately estimate the life cycles of our software
products. New products and product enhancements can require long development and
testing periods, and depend significantly on our ability to hire and retain
increasingly scarce technically competent personnel. Significant delays in new
product releases or significant problems in installing or implementing new
product releases could result in lost revenues and significant additional
expense.


     Our future success also depends, in part, on the compatibility of our
products with other vendors' software and hardware products, particularly those
provided by Microsoft. Developers of these products may change their products so
that they will no longer be compatible with our products. These other vendors
may also decide to bundle their products with other competing products for
promotional purposes. If that were to happen, our business and future operating
results might suffer as we might be priced out of the market or no longer be
able to offer commercially viable products.


WE HAVE EXPERIENCED ERRORS IN OUR PRODUCTS IN THE PAST, AND ANY SUCH ERRORS IN
THE FUTURE COULD HARM OUR REPUTATION AND COULD CAUSE CUSTOMERS TO DEMAND REFUNDS
FROM US OR ASSERT CLAIMS FOR DAMAGES AGAINST US, WHICH COULD HARM OUR BUSINESS
AND FUTURE OPERATING RESULTS



     Because our software products are complex, they have in the past, and could
in the future, contain errors or bugs. Bugs can be detected at any point in a
product's life cycle. In the past, we have devoted significant resources to the
detection and correction of errors and we expect to do so in the future. While
we continually test our products for errors and work with customers through our
customer support services and engineering personnel to identify and correct bugs
in our software, we expect that errors in our products, especially new releases
of our current products and new product offerings, will continue to be found in
the future. Any of these errors could be significant and could harm our business
and future operating results. Detection of any significant errors may result in:


     - the loss of or delay in market acceptance and sales of our products;

     - diversion of development resources;

     - injury to our reputation; or

     - increased maintenance and warranty costs.

     Because customers use our products to store and retrieve critical
information, we may be subject to significant liability claims if our products
do not work properly. Our agreements with customers typically contain provisions
intended to limit our exposure to liability claims. However, these limitations
may not preclude all potential claims. Liability claims could require us to
spend significant time and money in litigation or pay significant damages.
Claims of this nature, whether or not successful, could seriously damage our
reputation and our business.


OUR SOFTWARE PRODUCTS RELY ON OUR INTELLECTUAL PROPERTY, AND ANY FAILURE BY US
TO PROTECT, OR ANY MISAPPROPRIATION OF, OUR INTELLECTUAL PROPERTY COULD ENABLE
OUR COMPETITORS TO MARKET PRODUCTS WITH SIMILAR FEATURES THAT MAY REDUCE DEMAND
FOR OUR PRODUCTS



     Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy or otherwise obtain and use our products or technology.
Policing unauthorized use of our products is difficult, and we cannot be certain
that the steps we have taken will prevent misappropriation of our technology,
particularly in foreign countries where we are seeking to expand our operations
and where the laws may not protect our proprietary rights as fully as those in
the United States. Our success and ability to compete depend substantially upon
our internally developed technology, which is incorporated in the source code
for our products. We protect our intellectual property through a combination of
copyright, trade secret and trademark law. We have registered, or are in the
process


                                       11
<PAGE>   15


of registering, all of our trademarks under applicable law. We generally enter
into confidentiality or license agreements with our employees, consultants and
corporate partners, and control access to our source code and other intellectual
property and the distribution of our software, documentation and other
proprietary information. These measures afford only limited protection and may
be inadequate, especially because employees such as ours are highly sought after
and may leave our employ with significant knowledge of our proprietary
information. Others may develop technologies that are similar or superior to our
technology or design around the copyrights and trade secrets we own.


OUR PRODUCTS EMPLOY TECHNOLOGY THAT MAY INFRINGE THE PROPRIETARY RIGHTS OF
OTHERS, AND WE MAY BE LIABLE FOR SIGNIFICANT DAMAGES AS A RESULT


     We expect that our software products may be increasingly subject to
third-party infringement claims as the number of competitors in our industry
segment grows and the functionality of products in different industry segments
overlaps. We do not conduct comprehensive patent searches to determine whether
technologies used in our products infringe upon patents or patent applications
held by others. In addition, we hire employees who may be privy to the
proprietary information of their prior employers. Although we believe that our
products do not employ technology that infringes any proprietary rights of third
parties, third parties nevertheless may claim that we infringe their
intellectual property rights. Regardless of whether these claims have any merit,
they could:


     - be time-consuming to defend;

     - result in costly litigation;

     - divert our management's attention and resources;

     - cause product shipment delays; or

     - require us to enter into royalty or licensing agreements, which may not
       be available on terms acceptable to us, if at all.

     A successful claim of product infringement against us or our failure or
inability to license the infringed or similar technology could damage our
business because we would not be able to sell our products without redeveloping
them or incurring significant additional expenses.


THE EXPANSION OF OUR INTERNATIONAL OPERATIONS SUBJECTS OUR BUSINESS TO
ADDITIONAL ECONOMIC RISKS WHICH COULD HAVE AN ADVERSE IMPACT ON OUR REVENUE AND
BUSINESS



     In both 1998 and 1999, products we sold to customers outside North America
accounted for 6% of our total revenues. We plan to increase our international
sales activities, but these activities are subject to a number of risks,
including:


     - greater difficulty in accounts receivable collection and longer
       collection periods;

     - political and economic instability;

     - greater difficulty in attracting distributors that market and support our
       products effectively;

     - the need to comply with varying employment policies and regulations which
       could make it more difficult and expensive to manage our headcount if we
       need to establish more direct sales staff outside the United States;

     - weaker operating results from our international operations in our
       quarters ending each September 30 due to the summer slowdown in Europe;
       and

     - the effects of currency fluctuations.


     As we seek to expand our international operations, if any of these risks
materialize, our revenues and our business could be adversely affected.

ANY YEAR 2000 PROBLEMS WITH OUR PRODUCTS OR OUR INTERNAL SYSTEMS AND SOFTWARE
COULD RESULT IN THIRD-PARTY CLAIMS



     Many currently installed computer systems and software products are coded
to accept only two digit entries in the date code field. As a result, software
that records only the last two digits of the calendar year may not be able to
determine whether "00" means 1900 or 2000. This may result in software failures
or the creation of erroneous results even though the transition between 1999 and
2000 has passed.


     Our software products operate in complex system environments and directly
and indirectly interact with a number of other hardware and software systems.
Despite investigation and testing by us, our software products and the
underlying systems and protocols running our products may contain errors or
defects associated with Year 2000 date functions. Our vendors may also
experience Year 2000 problems that could affect our business. We are unable to
predict to what extent our business may be affected if our software or the
systems that operate in conjunction with our software experience a material Year
2000 failure or if our vendors experience Year 2000 problems. Known or unknown
errors or defects that affect the operation of our software could result in:

     - delay or loss of revenues, cancellation of customer contracts;

     - diversion of development resources;

     - damage to our reputation;

     - increased maintenance and warranty costs; and

     - litigation costs.

Any of these negative effects could adversely affect our business and future
results of operations. Furthermore, if our vendors experience Year 2000
problems, we could experience disruption in the provision of products and
services to our customers, which could have many of the negative effects
described above. In addition, if our customers experience their own Year 2000
problems, they may delay or forego purchases of our products until they have
addressed such problems, which could have an adverse effect on our business and
future operating results.


     Despite investigation and testing by us, our internal systems and/or
software may contain errors or defects associated with Year 2000 date functions
that we have not detected and corrected. We are unable to predict to what extent
our core business functions may be affected if our internal systems or software
experience a material Year 2000 failure. The section of this prospectus headed
"Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Year 2000 Readiness" contains a description of our Year 2000
readiness efforts.


RISKS RELATED TO THIS OFFERING


OUR STOCK MAY BE SUBJECT TO SUBSTANTIAL PRICE AND VOLUME FLUCTUATIONS DUE TO A
NUMBER OF FACTORS, INCLUDING THE FACT THAT WE ARE A TECHNOLOGY COMPANY, THAT MAY
PREVENT OUR STOCKHOLDERS FROM RESELLING OUR COMMON STOCK AT A PROFIT



     The securities markets have experienced significant price and volume
fluctuations, and the market prices of the securities of software and other
technology companies such as ours have been especially volatile. This market
volatility, as well as general economic, market or political conditions, could
reduce our stock price in spite of our operating performance. In addition, our
operating results could be below the expectations of public market analysts and
investors, and in response our stock price could decrease significantly.
Investors may be unable to resell their shares of our common stock at or above
the offering price. In the past, companies that have experienced volatility in
their stock


                                       13
<PAGE>   17

price have faced securities class action litigation. If we become the object of
securities class action litigation, it could result in substantial costs and a
diversion of management's attention and resources.

OUR OFFICERS, DIRECTORS AND PERSONS AFFILIATED WITH THEM CONTROL OUR BUSINESS
AND HOLD A MAJORITY OF OUR STOCK AND COULD REJECT MERGERS OR OTHER BUSINESS
COMBINATIONS THAT A STOCKHOLDER MAY BELIEVE ARE DESIRABLE


     We anticipate that our directors, officers and individuals or entities
affiliated with our directors as a group will beneficially own approximately
76.9% of our outstanding common stock after this offering closes. As a result,
these stockholders acting together would be able to determine the outcome of all
matters that our stockholders vote upon, including the election of directors and
mergers or other business combinations.


THE PROVISIONS OF OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY INHIBIT POTENTIAL
ACQUISITION BIDS THAT STOCKHOLDERS MAY BELIEVE ARE DESIRABLE, AND THE MARKET
PRICE OF OUR COMMON STOCK MAY BE LOWER AS A RESULT

     Our board of directors has the authority to issue up to 5,000,000 shares of
preferred stock. The board of directors can fix the price, rights, preferences,
privileges and restrictions of the preferred stock without any further vote or
action by our stockholders. The issuance of shares of preferred stock may delay
or prevent a change in control transaction. As a result, our stock price and the
voting and other rights of our stockholders may be adversely affected. The
issuance of preferred stock may result in the loss of voting control to other
stockholders. We have no current plans to issue any shares of preferred stock.

     Our charter documents contain anti-takeover devices including:

     - only one of the three classes of directors is elected each year;

     - stockholders have limited ability to remove directors without cause;

     - stockholders cannot act by written consent;

     - stockholders cannot call a special meeting of stockholders; and

     - stockholders must give advance notice to nominate directors or submit
       proposals for consideration at stockholder meetings.

In addition, we are subject to the anti-takeover provisions of Section 203 of
the Delaware corporate statute, which regulates corporate acquisitions. These
provisions could discourage potential acquisition proposals and could delay or
prevent a change in control transaction. They could also have the effect of
discouraging others from making tender offers for our common stock. As a result,
these provisions may prevent our stock price from increasing substantially in
response to actual or rumored takeover attempts. These provisions may also
prevent changes in our management.


THE SUBSTANTIAL NUMBER OF SHARES OF OUR COMMON STOCK THAT WILL BE ELIGIBLE FOR
SALE IN THE NEAR FUTURE COULD CAUSE OUR STOCK PRICE TO FALL



     Our current stockholders hold a substantial number of shares of our common
stock, which they will be able to sell in the public market in the near future.
Sales of a substantial number of shares of our common stock could cause our
stock price to fall. In addition, the sale of these shares could impair our
ability to raise capital through the sale of additional stock. The section
headed "Shares Eligible for Future Sale" appearing later in this prospectus
contains more information regarding the number of shares that may be sold in the
future by our existing stockholders and option holders.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements that involve
substantial risks and uncertainties. You can identify these statements by
forward-looking words such as "anticipate," "believe," "could," "estimate,"
"expect," "intend," "may," "should," "will" and "would" or similar words. You
should read statements that contain these words carefully because they discuss
our future expectations, contain projections of our future results of operations
or of our financial position or state other forward-looking information. We
believe that it is important to communicate our future expectations to our
investors. However, there may be events in the future that we are not able to
predict or control accurately. The factors listed above in the section headed
"Risk Factors," as well as any cautionary language in this prospectus, provide
examples of risks, uncertainties and events that may cause our actual results to
differ materially from the expectations we describe in our forward-looking
statements. Before you invest in our common stock, you should be aware that the
occurrence of the events described in these risk factors and elsewhere in this
prospectus could have a material adverse effect on our business, results of
operations and financial position.

                      TERMINATION OF S CORPORATION STATUS
                            AND RELATED DISTRIBUTION

     Since inception, we have elected to operate under subchapter S of the
Internal Revenue Code and comparable provisions of some state income tax laws.
An S corporation generally is not subject to income tax at the corporate level,
with some exceptions under state income tax laws. Instead, an S corporation's
income generally passes through to its stockholders and is taxed on their
personal income tax returns. As a result, our earnings have been taxed for
federal and state income tax purposes, with some exceptions, directly to our
existing stockholders.


     Prior to the closing of this offering, we will terminate our S corporation
status. Following the closing of this offering, we will make a distribution to
our existing stockholders of their aggregate federal and state income tax
liabilities attributable to our S corporation pass-through income for the years
1998, 1999 and the portion of 2000 prior to the termination of our S corporation
status of up to $1.6 million. This distribution will be made using a portion of
the net proceeds of this offering. The actual amount of this distribution will
be reduced to the extent distributions of accumulated earnings are made by us to
the existing stockholders prior to the date of this offering with other
corporate funds.



     The existing stockholders have agreed to indemnify us should our S
corporation status during any portion of the period for which we claimed such
status in federal or state income tax filings ever be successfully challenged,
up to an aggregate of $1.6 million. We cannot assure you that the amount of any
indemnity we recover from our existing stockholders would be sufficient to cover
the amount of any tax liability if our S corporation status is successfully
changed.



     In connection with the termination of our S corporation status, we may be
obligated to record a deferred tax asset or liability, which will be recognized
in the quarter during which this offering occurs.


                                       16
<PAGE>   20

                                USE OF PROCEEDS


     We estimate that our net proceeds from the sale of the 4,000,000 shares of
common stock we are offering will be approximately $46.6 million, assuming an
initial public offering price of $13.00 per share and after deducting estimated
underwriting discounts and commissions and estimated offering expenses payable
by us. We will not receive any of the proceeds from the sale of shares by the
selling stockholder.


     We will use a portion of the net proceeds of this offering to make the
following payments:


     - approximately $4.4 million to pay our outstanding senior subordinated
       notes, including notes held by a party which is an affiliate of a
       director and two parties which will be significant stockholders following
       this offering. The senior subordinated notes accrued interest at the rate
       of 8% per annum through June 9, 1999 and accrue interest at a rate of 10%
       after June 9, 1999. These notes become due upon the closing of this
       offering. As of January 31, 2000, the outstanding balance of principal
       and interest on the senior subordinated notes was $4.4 million;



     - approximately $2.0 million to repay loans from Richard A. Kay, our
       chairman, president and chief executive officer. These loans were made to
       provide working capital and bear interest at the rate of 8% per year. As
       of January 31, 2000, the outstanding balance of principal and interest on
       these loans was $2.0 million;



     - approximately $5.0 million to repay all outstanding balances under our
       commercial credit facility, which bears interest at the bank's prime rate
       plus 0.5% and becomes due on July 21, 2000. As of January 31, 2000, the
       outstanding balances of principal and interest on this credit facility
       was $5.0 million;



     - approximately $5.2 million to repay a note issued to a former stockholder
       in connection with the repurchase of his shares. This note bears interest
       at the rate of 10% per annum and becomes due 60 days after the closing of
       this offering. As of January 31, 2000, the outstanding balance of
       principal and interest under this note was $5.2 million;


     - approximately $250,000 to a former employee in respect of a deferred
       bonus due to him upon the closing of this offering; and


     - an amount, not to exceed $1.6 million, to our existing stockholders as a
       distribution to cover the aggregate federal and state income tax
       liabilities for 1998, 1999 and the portion of 2000 prior to termination
       of our S corporation status.


     We intend to use the remaining net proceeds of this offering for working
capital and general corporate purposes. Although we may use a portion of the net
proceeds to acquire businesses, products or technologies that are complementary
to our business, we have no specific acquisitions planned. Pending these uses,
we plan to invest the net proceeds in investment grade, interest-bearing
securities.

                                DIVIDEND POLICY


     We made distributions to our stockholders of approximately $60,000,
$600,000, $5.5 million and $34,000 during the years ended December 31, 1996,
1997, 1998 and 1999, respectively. Other than the estimated distribution of up
to $1.6 million to cover S corporation tax liabilities of our existing
stockholders following the closing of this offering, we do not anticipate paying
cash dividends in the foreseeable future. We currently intend to retain all
future earnings, if any, for use in the operation of our business. Our
commercial credit facility currently prohibits the payment of dividends other
than S corporation distributions.

                                 CAPITALIZATION


     The following table sets forth our capitalization and other financial
information as of December 31, 1999:


     - on an actual basis;


     - on a pro forma basis to reflect the automatic conversion of all
       outstanding convertible notes into common stock on the closing of this
       offering and the distribution at the closing of $1.6 million reflecting
       estimated S corporation tax liabilities of our existing stockholders; and


     - on a pro forma as adjusted basis to reflect the sale of the shares of
       common stock offered by us in this offering, our receipt and application
       of the estimated net proceeds, after deducting the estimated underwriting
       discounts and commissions and the estimated offering expenses that we
       expect to pay in connection with this offering, and our use of a portion
       of the net proceeds to repay debt.


This table also gives effect to an amendment to our charter filed after December
31, 1999 that increased the number of shares of common stock and preferred stock
authorized for issuance. You should read this table along with "Management's
Discussion and Analysis of Financial Condition and Results of Operations," our
financial statements and the related notes and the other financial information
in this prospectus.

     The outstanding share information excludes:


     - 3,489,106 shares of common stock issuable on exercise of outstanding
       options and a warrant as of December 31, 1999, at a weighted average
       exercise price of $2.65 per share; and



     - 594,116 shares of common stock reserved at that date for future issuance
       under our stock plan.



     After December 31, 1999, we issued options exercisable to purchase up to
464,500 shares of common stock at a weighted average exercise price of $12.64
per share. In addition, after December 31, 1999, we reserved an additional
1,600,000 shares for issuance under new stock plans.

                                    DILUTION


     Our pro forma net tangible deficit value as of December 31, 1999 was $14.4
million, or $(.71) per share of common stock. We have calculated this amount by:



     - subtracting our pro forma total liabilities from our pro forma total
       tangible assets, after giving effect to the automatic conversion of the
       convertible notes into common stock upon the closing of this offering and
       the distribution at the closing of $1.6 million, reflecting estimated S
       corporation tax liabilities of the existing stockholders; and


     - then dividing the difference by the total pro forma number of shares of
       common stock outstanding, including the number of shares of common stock
       that will be issued upon the conversion of the convertible notes issued
       by us when we complete this offering.


     If we give effect to our sale of 4,000,000 shares of common stock in this
offering at an assumed initial public offering price of $13.00 per share, after
deducting the estimated underwriting discounts and commissions and the estimated
offering expenses payable by us, our adjusted pro forma net tangible book value
as of December 31, 1999 would have been $32.2 million, or $1.31 per share. This
amount represents an immediate dilution of $11.69 per share to new investors.
The following table illustrates this per share dilution:

     If the underwriters exercise their over-allotment option in full, the
number of shares held by new investors will increase to 4,600,000 shares, or
18.8% of the total shares of common stock outstanding after this offering, and
the number of shares held by existing stockholders will be reduced to 19,876,188
shares, or 81.2% of the total shares of common stock outstanding after this
offering.

     The table above assumes no exercise of stock options and a warrant
outstanding at December 31, 1999. As of December 31, 1999, there were options
and a warrant outstanding to purchase 3,489,106 shares of common stock at a
weighted average exercise price of $2.65 per share and 594,116 shares reserved
for future grant or award under our stock plan. To the extent any of these
options or warrants are exercised, there will be further dilution to new
investors. To the extent all of these outstanding options or the warrant had
been exercised as of December 31, 1999, net tangible book value per share after
this offering would have been $1.13 and total dilution per share to new
investors would have been $11.87.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


     You should read the following discussion and analysis in conjunction with
our consolidated financial statements and the related notes included elsewhere
in this prospectus.


OVERVIEW


     We are a leading provider of online data storage management and data access
software solutions. Our software enables enterprises to move, store, manage and
access data quickly and efficiently over a variety of network architectures,
including the Web and storage area networks. Our software supports many
different types of storage devices, is easy to install and use, and can manage
storage systems ranging in size from a single storage device to an
enterprise-wide data storage network.



     We were founded in March 1992. Since our inception, we have incurred
significant losses. For 1999, our net loss was $1.5 million. As of December 31,
1999, we had an accumulated deficit of $22.4 million. We expect to incur
significant research and development, sales and marketing and general and
administrative expenses, and, as a result, we will need to generate significant
revenues to achieve and maintain profitability. Although our revenues have
grown, we may not be able to sustain these growth rates, and we may not realize
sufficient revenues to achieve profitability.


     We generate revenues principally from licensing our software products and
providing related professional services including maintenance and technical
support, consulting and training.


     We derive software license revenues from licenses of our software programs
to customers primarily through indirect sales channels, including original
equipment manufacturers, value-added resellers and distributors. We also sell
through our direct sales force. Original equipment manufacturers either bundle
our products with the products they offer or resell our products under their own
label. We receive software license revenues each time an original equipment
manufacturer licenses a copy of its products that incorporates one or more of
our products. Our license agreements with original equipment manufacturers
generally contain no minimum sales requirements and we cannot assure you that
any original equipment manufacturer will either commence or continue shipping
our products in the future. Moreover, following the execution of new license
agreements, a significant period of time may elapse before any revenues are
generated due to the development work which we often undertake under these
agreements and the time needed for the sales and marketing groups within these
original equipment manufacturers, customers and resellers to become familiar
with our products.



     Our services revenues consist of fees derived from annual maintenance
agreements, consulting and training and other services. The maintenance
agreements covering our products provide for technical support and minor
unspecified product upgrades for fees based on the number of software licenses
purchased and the level of service chosen by the customer. Maintenance fees are
recognized ratably over the term of the maintenance contract. We provide
consulting services, for which we charge a fee based upon the amount of time
worked and the cost of the materials used in providing the services. We provide
classroom and on-site training to our customers on a daily fee basis.



     Our international sales are primarily generated through indirect sales
channels. Revenues derived from customers located outside the United States and
Canada, most of which are denominated in U.S. currency, accounted for
approximately 6% of our total revenues in each of 1998 and 1999. Our
international revenues increased 32% from $1.1 million for 1998 to $1.5 million
for 1999.


     We currently have sales and services offices in the United States and
provide sales and services support in Europe through employees located in
Germany and the Netherlands. We plan to expand our international operations by
establishing additional foreign offices, hiring additional personnel and
recruiting additional international resellers.

COMPARISON OF YEARS ENDED DECEMBER 31, 1998 AND 1999


     Revenues


     Total revenues increased 47% from $17.3 million for 1998 to $25.4 million
for 1999. We believe that the percentage increase in total revenues achieved in
this period is not necessarily indicative of future results. Our revenues
consist of software license revenues and services revenues. Software license
revenues are derived primarily from licenses of our software products. Services
revenues are derived primarily from contracts for software maintenance and
technical support and, to a lesser extent, consulting, training and other
services. We also experienced an increase in demand for consulting and training
services directly associated with the sale of new software licenses. Software
license revenues were 70% of total revenues for 1998, and 72% of total revenues
for 1999.



     Software License Revenues.  Software license revenues increased 51% from
$12.1 million for 1998 to $18.2 million for 1999. The increase was primarily due
to an increase in overall demand for data storage management products,
increasing market acceptance of our products, introduction of new products and
increasing revenues generated through our indirect sales channels.



     Services Revenues.  Services revenues increased 38% from $5.2 million for
1998 to $7.2 million for 1999. The increase was primarily due to increased sales
of services and support contracts on new


                                       24
<PAGE>   28

license sales, increased renewals of these contracts by our installed base of
licensees and, to a lesser extent, increased demand for consulting and training
services.

     Cost of Revenues

     Cost of software license revenues consists primarily of royalties, media,
manuals and distribution costs. Cost of services revenues consists primarily of
personnel-related costs in providing maintenance and technical support,
consulting and training to customers. Gross margin on software license revenues
is substantially higher than gross margin on services revenues, reflecting the
low materials, packaging and other costs of software products compared with the
relatively high personnel costs associated with providing maintenance and
technical support, consulting and training services. Cost of services revenues
varies based upon the mix of maintenance and technical support, consulting and
training services.


     Cost of Software License Revenues.  Cost of software license revenues
increased 100% from $532 for 1998 to $1,062 for 1999. Gross margin on software
license revenues decreased from 96% for 1998 to 94% for 1999, primarily because
of higher product packaging and distribution costs in 1999. The gross margin on
software license revenues may vary from period to period based on the software
license revenues mix and certain products having higher royalty rates than other
products. We do not expect significant improvements in gross margin on software
license revenues.



     Cost of Services Revenues.  Cost of services revenues increased 84% from
$1.6 million for 1998 to $3.0 million for 1999. Gross margin on services
revenues decreased from 69% for 1998 to 58% for 1999. The increased cost and the
reduced margin was primarily due to personnel additions in our customer support
and training and consulting organizations, in anticipation of increased demand
for these services. The gross margin on services revenues may vary from period
to period based upon the mix of maintenance and technical support, consulting
and training services.


     Operating Expenses


     Research and Development.  Research and development expenses consist
primarily of salaries, related benefits and other engineering-related costs.
Research and development expenses increased 30% from $4.0 million for 1998 to
$5.1 million for 1999. The increase was due primarily to increased staffing
levels. As a percentage of total revenues, research and development expenses
decreased from 23% for 1998 to 20% for 1999. We believe that a significant level
of research and development investment is required to remain competitive, and
expect that the dollar amount of these expenses will continue to increase in
future periods.



     Sales and Marketing.  Sales and marketing expenses consist primarily of
salaries, related benefits, commissions, consultant fees, tradeshow, advertising
and other costs associated with our sales and marketing efforts. Sales and
marketing expenses increased 28% from $9.0 million for 1998 to $11.5 million for
1999, which includes $36,000 in non-cash compensation expense. The increase in
sales and marketing expenses is attributable to an increase in the number of
sales and marketing employees and increases in marketing programs. Sales and
marketing expenses as a percentage of total revenues decreased from 52% for 1998
to 45% for 1999. The decrease as a percentage of total revenues was primarily
due to the increase in total revenues. We intend to continue to expand our
global sales and marketing infrastructure and, accordingly, we expect our sales
and marketing expenses to increase in the future.



     General and Administrative.  General and administrative expenses consist
primarily of salaries, related benefits and fees for professional services, such
as legal and accounting services. General and administrative expenses increased
93% from $2.2 million for 1998 to $4.1 million for 1999, which includes $623,000
in non-cash compensation expense. General and administrative expenses as a
percentage of total revenues increased from 12% for 1998 to 16% for 1999. The
increase was

                                       25
<PAGE>   29

primarily due to additional personnel costs and other expenses associated with
enhancing our infrastructure to support expansion of our operations. We expect
that the dollar amount of general and administrative expenses will increase as
we expand our operations.


     Interest Expense, Net.  We incur interest expense on debt from a revolving
credit agreement, which bears interest at a rate of 0.5% over the bank's prime
lending rate, on notes payable to certain current and previous stockholders,
which bear interest at various rates from 8% to 10%, and on senior debt and
convertible debt from our investors. Our senior debt and convertible debt was
established in the amounts of approximately $4.4 million and $7.6 million,
respectively, in the second quarter of 1998 and bear interest at various rates
from 8% to 12%. Interest expense increased 63% from $1.3 million for 1998 to
$2.1 million for 1999.



     Pro Forma Income Tax Provision (Benefit).  Because we incurred net
operating losses in 1998 and in 1999, our pro forma effective tax rate in each
year was zero.



COMPARISON OF YEARS ENDED DECEMBER 31, 1997 AND 1998


     Revenues


     Total revenues increased 45% from $11.9 million in 1997 to $17.3 million in
1998. We believe that the percentage increase in total revenues achieved in this
period is not necessarily indicative of future results.



     Software License Revenues.  Software license revenues increased 42% from
$8.5 million in 1997 to $12.1 million in 1998. The increase was primarily the
result of continued growth in market acceptance of our software products, a
greater volume of large end-user transactions, increased revenues from original
equipment manufacturer resales of bundled and unbundled products and the
introduction of new products. Software license revenues growth also resulted
from increases in direct sales and indirect sales other than through original
equipment manufacturers.



     Services Revenues.  Services revenues increased 56% from $3.4 million in
1997 to $5.2 million in 1998. The increase was primarily due to increased sales
of services and support contracts on new licenses, renewal of services and
support contracts on existing licenses and the growth in services provided by
our professional services staff.


     Cost of Revenues


     Cost of Software License Revenues.  Cost of software license revenues
decreased 8% from $579,000 in 1997 to $532,000 in 1998. The decrease was
primarily the result of lower product packaging and distribution costs. Gross
margin on software license revenues was 93% and 96%, respectively, in 1997 and
1998.



     Cost of Services Revenues.  Cost of services revenues increased 34% from
$1.2 million in 1997 to $1.6 million in 1998. Gross margin on services revenues
was 64% and 69% in 1997 and 1998, respectively. The change in gross margin was
primarily due to personnel additions in our customer support and training and
consulting organizations, in anticipation of increased demand for these
services, as well as to a change in the mix of contracts for services with
varying margins.


     Operating Expenses


     Research and Development.  Research and development expenses increased 61%
from $2.5 million in 1997 to $4.0 million in 1998. The increase in both periods
was due primarily to increased staffing levels. As a percentage of total
revenues, research and development expenses were 21% and 23% in 1997 and 1998,
respectively.



     Sales and Marketing.  Sales and marketing expenses increased 69% from $5.3
million in 1997 to $9.0 million in 1998. Sales and marketing expenses as a
percentage of total revenues were 45% and


                                       26
<PAGE>   30


52% in 1997 and 1998, respectively. The dollar increase was primarily
attributable to increased sales and marketing staffing and, to a lesser extent,
increased costs associated with new marketing programs.



     General and Administrative.  General and administrative expenses increased
26% from $1.7 million in 1997 to $2.2 million in 1998. General and
administrative expenses as a percentage of total revenues were 14% and 12% in
1997 and 1998, respectively. The dollar increase in 1998 was primarily due to
additional personnel costs and other expenses associated with enhancing our
infrastructure to support expansion of our operations.



     Interest Expense, Net.  Interest expense, net was $162,000 for 1997 and
$1.3 million for 1998.



     Pro Forma Income Tax Provision (Benefit).  As a result of net loss
carryforwards in 1997 and as a result of our net operating losses in 1998, our
pro forma effective tax rate in each year was zero.


QUARTERLY RESULTS OF OPERATIONS


     The following table sets forth items from our statements of operations for
the last eight quarters, as well as that data expressed as a percentage of our
total revenues. This data has been derived from unaudited combined financial
statements that, in the opinion of management, include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of this information. We believe that period-to-period comparisons
of our financial results are not necessarily meaningful and should not be relied
upon as an indication of future performance.

</TABLE>


     The trends discussed in the period-to-period comparisons above generally
apply to the results of operations for our seven most recent quarters, except
for certain differences discussed below.


     Services revenues increased every quarter since March 31, 1998, except for
the quarter ended September 30, 1999. This exception was because we performed an
unusually large amount of consulting services during the prior quarter ended
June 30, 1999.


     Cost of software license revenues have remained relatively constant quarter
to quarter as a percentage of software license revenues. Cost of software
license revenues increased substantially in absolute terms in the quarter ended
December 31, 1998 due to a substantial investment in our shipping and packaging
infrastructure. Cost of services revenues as a percentage of services revenues
has fluctuated as the mix of services performed for our customers has varied
among higher and lower margin services.


     Total operating expenses have fluctuated primarily as a result of
variations in our sales and marketing expenses. In each of the quarters ended
June 30, 1998, December 31, 1998, June 30, 1999 and December 31, 1999, we
incurred additional sales and marketing expenses associated with trade shows and
significant marketing programs. To a lesser extent, our operating expenses have
fluctuated as a result of costs associated with recruiting and hiring research
and development personnel.


     We expect to experience significant fluctuations in future quarterly
operating results that may be caused by many factors including, among other
things, the release of software products by us or our competitors, market
acceptance of our products, the mix of our products and services sold, demand
for our products or the timing of customer acceptance of our products, renewal
of service agreements, software quality, changes in the level of operating
expenses and general economic conditions. Due to these and other factors, our
quarterly revenues and operating expenses are difficult to forecast accurately.

LIQUIDITY AND CAPITAL RESOURCES


     Our cash and cash equivalents totaled $2.5 million at December 31, 1999,
and represented 20% of total assets. Cash equivalents are highly liquid
instruments with original maturities of 90 days or less. At December 31, 1999,
we had $17.3 million of long-term obligations, and stockholders' deficit was
approximately $21.7 million.



     For 1999, cash provided by operating activities of $765,000 resulted
primarily from an increase in accounts payable, non-cash expenses, accrued
expenses and deferred revenues. This was partially offset by a net loss and an
increase in prepaid expenses. For 1998, net cash used in operating activities of
$1.3 million resulted primarily from net losses and increases in accounts
receivable and prepaid expenses. This was partially offset by increases in
accounts payable, accrued expenses and deferred revenues. For 1998, cash used in
operating activities resulted primarily from net losses and an increase in
accounts receivable, prepaid assets and other assets. This was partially offset
by increases in accrued expenses and deferred revenues. Net cash provided by
operating activities was $896,000 in 1997. Increases in cash provided by
operating activities in 1997 resulted from increases in accounts payable,
accrued expenses, deferred revenues and net income.



     Our investing activities used cash of $928,000, $667,000 and $654,000 in
1999, 1998 and 1997, respectively, primarily for capital expenditures.



     Financing activities provided cash of $2.2 million in 1999, primarily from
increased net borrowings from the bank of $2.7 million, and provided cash of
$1.3 million in 1998 primarily from the net proceeds of $12.1 million under the
Company's senior subordinated notes and convertible subordinated debt, which
were issued on June 9, 1998. Borrowings from the bank bear interest at the
bank's prime rate plus 1% and become due on July 21, 2000. The senior
subordinated notes and convertible subordinated debt bore interest at 8% through
June 1999, bear interest at 10% from June 9, 1999 through June 9, 2000 and bear
interest at 12% from June 9, 2000 through maturity, and are due and payable on
December 9, 2000, with interest payments due quarterly after inception. In
specified events, such as the closing of this offering, the notes are
accelerated and become due in full. In specified events, such as the closing of
this offering, the convertible subordinated debt is converted into shares of
common stock at a rate of $3.67 per share, and interest, which has been accrued
cumulatively since the inception of the convertible subordinated debt, is
forgiven. Financing activities provided cash of $570,000 in 1997, primarily from
borrowings under notes payable to the bank and borrowings under long term debt,
offset by distributions to stockholders and redemptions of common stock.



     In March 1992, we entered into a loan agreement and related promissory note
with Mr. Kay in order to secure working capital for our operations. As amended,
the loan agreement and promissory note provide for a maximum principal amount of
indebtedness of $1,000,000 and make the promissory note payable upon demand.
Amounts that we borrow under the loan agreement bear simple interest at a rate
of 8% per year. As of January 31, 2000, we owed Mr. Kay $469,000 as a result of
borrowings and accrued interest under this arrangement.



     In addition, on June 16, 1998, we borrowed an aggregate principal amount of
$1,500,000 from Mr. Kay in order to secure working capital for our operations
pursuant to two promissory notes. These notes earn 8% interest which is payable
quarterly. The principal amount of these notes is due and payable upon the
earlier of December 16, 2000 or 60 days after the closing of this offering, a
qualified merger or a sale of substantially all of our assets.


     We believe that our current cash, cash equivalents, cash flow from
operations, and loans from our principal stockholder, will be sufficient to meet
our expected working capital and capital expenditure requirements for at least
the next twelve months. After that, we may require additional funds to support
our working capital requirements or for other purposes and may seek to raise
such

                                       29

additional funds through public or private equity financing or from other
sources. We cannot assure you that additional financing will be available at all
or that, if available, we will be able to obtain it on terms favorable to us.


YEAR 2000 READINESS



     Many currently installed computer systems and software products are coded
to accept only two digit entries in the date code field. As a result, software
that records only the last two digits of the calendar year may not be able to
determine whether "00" means 1900 or 2000. This may result in software failures
or the creation of erroneous results. Although the transition from 1999 to 2000
has passed and we are not aware of any Year 2000 problems with our products, our
internal systems or our vendors, it is possible that Year 2000 problems could be
discovered in the future.


     Our software products operate in complex system environments and directly
and indirectly interact with a number of other hardware and software systems. We
have tested the current versions of our products and the versions of our
products under development, as well as our internal systems, and believe that
they are Year 2000 compliant. In addition, we have inquired of our vendors who
provide us with goods and services as to their state of Year 2000 readiness.
Despite testing and investigation by us, our software products and the
underlying systems and protocols running our products may contain errors or
defects associated with Year 2000 date functions. Our vendors may also
experience Year 2000 problems that could affect our business. We are unable to
predict to what extent our business may be affected if our software or the
systems that operate in conjunction with our software experience a material Year
2000 failure or if our vendors experience Year 2000 problems. Known or unknown
errors or defects that affect the operation of our software could result in:

     - delay or loss of revenues, cancellation of customer contracts;

     - diversion of development resources;

     - damage to our reputation;

     - increased maintenance and warranty costs; and

     - litigation costs.

Any of these negative effects could adversely affect our business and future
results of operations. Furthermore, if our vendors experience Year 2000
problems, we could experience disruption in the provision of products and
services to our customers which could have many of the negative effects
described above. In addition, if our customers experience their own Year 2000
problems, they may delay or forego purchases of our products until they have
addressed such problems, which could have an adverse effect on our business and
future operating results.


     The total cost of our Year 2000 compliance activities was not material to
our business, results of operations and financial conditions. We estimate
specific Year 2000 expenses did not exceed $300,000. While we believe that we
have completed our Year 2000 readiness process, we cannot assure you that we
have identified and remedied all significant Year 2000 problems, that we will
not incur significant additional time and expense or that such problems will not
harm our business.



QUALITATIVE AND QUANTITATIVE DISCLOSURE OF MARKET RISK


     We do not currently have any derivative financial instruments and do not
intend to invest in derivatives. We invest our cash in short-term highly liquid
cash equivalents. All of our indebtedness will be automatically converted into
equity or repaid upon completion of this offering. As a result, we believe that
our exposure to interest rate risk is not material to our results of operations.

NEW ACCOUNTING PRONOUNCEMENTS



     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." SFAS No. 133 establishes methods of accounting for
derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities. We will be required to
implement SFAS No. 133 for the year ending December 31, 2001. We have not
entered into any foreign currency exchange rate hedging activities to date and
we do not believe that the impact of SFAS No. 133 will be material to our
financial position, results of operations or cash flows.


     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." SOP 98-1 requires that
entities capitalize certain costs related to internal-use software once certain
criteria have been met. We adopted SOP 98-1 as of January 1, 1999. The impact of
adopting SOP 98-1 was not material, and we do not expect SOP 98-1 to have a
material impact on our financial position, results of operations and cash flows.

     In December 1998, the AICPA issued SOP 98-9, "Modification of SOP 97-2,
Software Revenue Recognition, with Respect to Certain Transactions." SOP 98-9
amends SOP 97-2 "Software Revenue Recognition" to require recognition of revenue
using the "residual method" when certain criteria are met. We will be required
to implement these provisions of SOP 98-9 for the year ending December 31, 2000.
Effective in December 1998, SOP 98-9 also amends SOP 98-4, an earlier amendment
to SOP 97-2, to extend the deferral of the application of certain passages of
SOP 97-2 provided by SOP 98-4. We do not believe the impact of SOP 98-9 will be
material to our financial position, results of operations and cash flows.


     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101-Revenue Recognition in Financial Statements. This
SAB expresses the SEC's views in applying generally accepted accounting
principles to revenue recognition in financial statements. Companies can apply
the accounting and disclosure requirements of this SAB retrospectively, or may
report a change in accounting principle no later than the first fiscal quarter
of the fiscal year beginning after December 15, 1999. We do not expect the
application of this SAB to have a material impact on our financial statements.

                                    BUSINESS

OVERVIEW


     We are a leading provider of online data storage management and data access
software solutions. Our software enables enterprises to move, store, manage and
access data quickly and efficiently over a variety of network architectures,
including the Web and storage area networks. Our software supports many
different types of storage devices, is easy to install and use, and can manage
storage systems ranging in size from a single storage device to an
enterprise-wide network storage system.


INDUSTRY BACKGROUND

     The growth of data storage

     The growth of data-intensive computing functions such as e-commerce,
e-mail, multimedia applications, complex enterprise computer applications and
the conversion from paper to electronic storage has fueled rapid growth in the
amount of data stored within an enterprise. For example, International Data
Corporation, an independent information technology research firm referred to as
IDC, projects that the number of e-mail messages sent per day in the United
States will grow from approximately 3.5 billion in 1999 to 9.2 billion in 2003.
This growth has resulted in an increased demand for more efficient methods to
store and retrieve data. IDC estimates that multi-user disk storage grew from
more than 7,000 terabytes in 1993 to more than 188,000 terabytes in 1999, and
will reach more than 1.9 million terabytes in 2003. A byte is the amount of
computer memory required to store one number, letter or symbol; a terabyte is
equal to one trillion bytes.

     This dramatic growth in data storage is driving the demand for many types
of storage technology, such as new storage devices, networking hardware, network
transmission technology and software. Many enterprises are trying to manage
larger amounts of data, creating a demand for solutions that can automate this
task. Industry analysts predict that demand for data storage software in
particular will grow significantly. IDC estimates that the overall market for
data protection and management software grew from $2.1 billion in 1996 to $3.5
billion in 1998 and will grow to $6.7 billion in 2003.

     Traditional data storage and back-up

     Users traditionally have stored data on hard disks or other storage devices
connected to their personal computers or computer networks, a configuration
referred to as primary storage. In addition to primary storage, enterprises have
widely adopted back-up processes to insure against the loss of data by creating
and storing duplicates of existing data files. The traditional back-up process
moves data to secondary storage devices not directly accessible by users and
applications. Typically, an enterprise will perform a full back-up of all data
once a week and incremental back-ups on each of the other six days of the week.
An incremental back-up operation copies only those files that have changed since
the last full back-up. There are several significant problems with traditional
data storage and back-up methods:

     - Expensive primary storage capacity is consumed rapidly. Hard drives and
       other storage devices used for primary storage are more expensive than
       remote and back-up storage devices and have a limited capacity. This
       capacity is often quickly exhausted, and the user or the enterprise must
       then either purchase additional capacity or delete data. An enterprise
       incurs additional expense not only for the purchase of additional storage
       devices, but also for the administrative time required to install,
       allocate and manage this additional primary storage capacity.

     - Repetitive back-up consumes network transmission capacity. As the amount
       of data increases, repeatedly backing up the same data consumes
       increasing amounts of network transmission

                                       32
<PAGE>   36

       capacity, or bandwidth. Computer networks have a limited amount of
       bandwidth, and most of this capacity is consumed during business hours by
       the demands of the network's users. As a result, networks lack the
       capacity to transmit data to storage devices for back-up during business
       hours. In addition, as enterprises expand their operations
       internationally, as the Internet makes networks more accessible and as
       the workday becomes longer, the number of hours available each day for
       back-up is shrinking. As a result, network administrators have smaller
       windows of time in which they can back up increasing amounts of data
       without impairing the performance or accessibility of the network.

     - Failure to manage data results in an inefficient back-up process. Most
       files on a typical file server are not frequently accessed more than 30
       days after they are created. Repeatedly backing up the same unchanged
       data consumes more back-up storage capacity unnecessarily, and requires
       an enterprise to expand its storage capacity with each subsequent
       back-up. In addition, because network administrators cannot determine
       which files are important, they either save most files or randomly delete
       them.

     - Access to stored data is limited.  Infrequently accessed data is
       typically migrated from primary storage devices to secondary storage
       devices, such as tape libraries. Once this process has occurred, the time
       and effort necessary to retrieve a migrated file is significant. A user
       will need to know information such as the file name, the original storage
       location and the date of the back-up. When this information has been
       determined, the network administrator will then use this information to
       retrieve the file manually. This process is inefficient for the user, who
       must wait for the needed file, and for the network administrator, who
       must act as an intermediary and retrieve the file. In addition, files
       that have been deleted from primary storage and only reside on secondary
       storage devices are not readily accessible to software applications that
       may need the data contained in the file.

     The emergence of storage area networks


     In response to the limitations of traditional data storage and back-up
methods, storage area networks have emerged. A storage area network is a network
of servers and data storage devices that are interconnected at high speeds,
typically using Fibre Channel transport technology, which allows network
resources to be located at remote and diverse locations. Enterprises are
increasingly deploying storage area networks in an effort to move data storage
operations off of their local area networks to a separate network dedicated to
data storage. Moving these operations to storage area networks frees up
bandwidth on the local area network for more efficient operation of enterprise
software applications and communications. Storage area networks can be
significantly less expensive to maintain and expand than traditional data
storage systems because they enable shared, high-speed access to stored data.
IDC estimates that the overall storage area network market will grow from $3.4
billion in 1999 to $13.8 billion in 2003.



     Despite the greater capacity and speed offered by storage area networks,
storage area networks do not address the need to make management and access of
data more efficient. In particular, storage area networks fail to determine
which data should be stored, do not provide efficient transfer of data to the
storage area network, do not enable immediate access to backed-up data and
cannot provide an effective index of stored data.


     The need for data storage management software


     In order to address the problems of traditional storage and back-up
methods, and to take advantage of the power of storage area networks, a data
storage solution must:


     - automatically apply policies that determine whether, or for how long,
       data should be stored;

                                       33
<PAGE>   37


     - provide efficient transfer of data to and from storage devices throughout
       networks, including local area networks and storage area networks;


     - provide a detailed index of stored data;

     - enable rapid and easy retrieval of stored data selected by users and
       software applications;

     - maximize the effective capacity of existing storage devices; and

     - provide secure Web access to stored data.

THE OTG SOLUTION

     We are a leading provider of online data storage management and data access
solutions. Our Windows NT-based solutions provide customers with the following
benefits:


     - Efficient use of storage capacity.  We enable automated data migration to
       less expensive remote storage devices and networks.


     - Fast data access.  We provide quick and easy access to data for users and
       software applications, including secure Web access.

     - Increased efficiency of back-up systems.  We reduce the time required for
       data back-up, maximize use of back-up storage capacity and increase
       available network bandwidth by eliminating the repetitive back-up of
       unchanged data.

     - Diverse storage options.  We support many different types of data storage
       devices within the same data storage system to maximize performance and
       minimize cost.


     - Fast and easy installation and use.  We make installation, configuration
       and use quick and easy, using an intuitive graphical user interface,
       which allows a user to interact with our product through the use of
       windows and icons in a point-and-click system.


     - Flexibility and scalability.  Our solutions expand quickly and easily to
       accommodate changes in the size of a data storage system from a single

       support additional users and applications.

THE OTG STRATEGY

     Our objective is to extend our position as a leading provider of online
data storage management and data access solutions. To achieve this objective, we
intend to:


     Expand our presence in the storage area network market.  We intend to
expand the current use of our XtenderSolutions product suite in the storage area
network market by introducing SANXtender. This product will customize our
existing technology to maximize the capabilities of storage area networks.
SANXtender will provide data storage management over the storage area network by
linking storage area network technologies to local area network applications. In
developing SANXtender, we are conducting quality assurance and compatibility
testing of our products with the products of manufacturers of storage area
network technologies, such as ATL Products, Chaparral Network Storage, Advanced
Digital Information Corporation, Emulex Corporation and Hewlett-Packard, to
ensure that SANXtender will be certified as compatible with leading storage area
network hub, switch, router and storage technologies. In addition, we are
pursuing alliances with other leading storage area network companies.


     Capitalize on the release of Windows 2000.  We plan to introduce a new
version of DiskXtender, called DiskXtender 2000, shortly after the release of
Windows 2000. DiskXtender 2000 will allow our existing technology to operate on
the Windows 2000 platform. We believe our engineering history with the Windows
NT code and our access to pre-release versions of Windows

                                       34
<PAGE>   38

2000 will enable us to offer a closely integrated version of DiskXtender 2000 in
a timely fashion. Over time, we will integrate the XtenderSolutions product
suite with new features provided by Windows 2000.


     Provide solutions to address e-mail storage management.  To meet
accelerating demand for e-mail storage management solutions, we are building on
our DiskXtender technology to develop eMailXtender, an e-mail indexing,
archiving and retrieval application, and integrating it with leading e-mail
applications. A preliminary version of this product, currently being implemented
by Merrill Lynch, allows users to conduct full-text searches, archive to
secondary or removable storage devices, and retrieve e-mail messages and
e-commerce transaction documents.



     Offer our storage solutions over the Web through Internet service provider
and application service provider relationships.  We intend to expand our
capability to enable our customers to outsource data storage management and
capacity over the Web, through relationships with Internet service providers and
application service providers. As Internet access becomes faster and more
secure, we anticipate that increasing numbers of enterprises will turn to leased
or metered online storage solutions as a cost-effective alternative to in-house
capabilities. We intend to offer this capability through Internet service
providers and application service providers under the name OnlineStor.com.
OnlineStor.com will enable individual users and enterprises to store and manage
data over the Web with functionality similar to that of DiskXtender at
substantial hardware and maintenance cost savings over in-house storage systems.


     Enable our core technology to run on additional operating systems.  We are
currently modifying our DiskXtender technology to operate on the UNIX and Linux
operating systems. These new versions of our products will provide the ability
to manage data on UNIX and Linux file servers in addition to the Windows NT
servers currently supported today.

     Our product pricing is generally established on a per license basis. An
example of a representative customer's requirements would include the need to
move, store, manage and access approximately 10 terabytes of data by 25 users
accessing the data from the customer's network and 100 users accessing data over
the Web supported by three servers. Under this scenario, a product configuration
would include:


          - DiskXtender.  The list price of DiskXtender for two Storage Tek
            9740-100 tape libraries (representing 10 terabytes of data) is
            approximately $50,000. In addition, the customer would need to
            purchase four additional DiskXtender agent licenses to support the
            remote storage servers required in its network for a total list
            price of $56,000.


          - ApplicationXtender.  To support 25 users accessing the data from the
            network, the customer would need to purchase 25 concurrent
            ApplicationXtender licenses at a list price of approximately
            $25,000.


          - WebXtender.  To support 100 Web users, the customer would need to
            purchase both a Web server component at a list price of
            approximately $10,000 and 100 concurrent WebXtender licenses at a
            list price of approximately $41,000.



     The list price for this XtenderSolutions configuration would be
approximately $132,000, with annual maintenance fees of approximately $25,000.

     Current products


     DiskXtender.  The cornerstone of our product suite is DiskXtender.
DiskXtender is a server-based, Windows NT solution that enables management of
data throughout an enterprise's network while tracking and managing stored file
locations. DiskXtender enhances a data storage system by increasing its primary
storage capacity and providing constant accessibility to data while integrating
stored files with other enterprise applications. DiskXtender uses advanced
features such as caching technologies, which temporarily store frequently
accessed or recently accessed data and thereby speed up an application's access
to data. DiskXtender is currently the only Windows NT storage solution that
manages all major types of storage devices, from optical and tape to CD-ROM and
DVD. We provide a DiskXtender application programming interface allowing
end-users and original equipment manufacturers to integrate DiskXtender with
software applications, such as Web browsers, word processing, accounting and
imaging.


     DiskXtender has won the following awards, among others:

     - 1999 Solutions Integrator Impact Award for Best Storage Product from
       International Data Group, the parent of IDC; and

     - 1998 and 1999 Product of the Year Awards from Imaging & Document
       Solutions magazine.


     ApplicationXtender.  ApplicationXtender organizes and stores data used by
Windows-based applications and enables users to display, print, fax, e-mail or
annotate the stored data. Because ApplicationXtender integrates the host
applications chosen by the end-user with DiskXtender technology, end-users can
access, retrieve, control and view data through the host applications. As with
DiskXtender, an application programming interface toolkit allows customers and
original equipment manufacturers to integrate ApplicationXtender with existing
applications.


     WebXtender.  WebXtender provides access to data over an enterprise's
intranet or the Internet using standard Web browser interfaces. WebXtender
offers data display and search functionality in any ApplicationXtender
application, while providing remote access to stored data. Because WebXtender
requires only a standard Web browser to be installed on the user's workstation,
WebXtender minimizes overhead and costs of client software distribution and
configuration.

     ColdXtender.  ColdXtender manages the storage of computer-generated output
data for use in preparing forms and reports in standardized formats, such as
insurance claims and reports. ColdXtender stores, compresses and catalogues
report data in searchable databases.

     Products under development

     We plan to introduce several products in the near future to address
emerging storage management requirements. These include:


     SANXtender.  SANXtender will apply our XtenderSolutions technology to
maximize the performance of a storage area network. SANXtender will provide data
storage management over a storage area network by linking storage area network
technologies to local area network applications. This will allow data transfer
and storage without moving data through servers on the local area network,
thereby freeing the resources of the local area network for user applications.
As part of our development efforts, we are conducting quality assurance and
compatibility testing of our products with the products of manufacturers of
storage area network technologies, such as ATL Products, Chaparral Network
Storage, Advanced Digital Information Corporation, Emulex Corporation and
Hewlett-Packard, to ensure that SANXtender will be certified as compatible with
leading storage area network hub, switch, router and back-up technologies. In
addition, we are pursuing alliances with other leading storage area network
companies. SANXtender is primarily based on our existing technologies and
products. Our current efforts are focused on developing DiskXtender storage
management for storage area networks, while connecting storage area networks
with the Internet and

                                       37

other applications. We anticipate general commercial availability of this
product during the third quarter of 2000.



     OnlineStor.com. We are adapting our products to be offered as an outsourced
data storage and management service under the name OnlineStor.com. These
services will be offered on a metered or leased basis through Internet service
providers and application service providers. OnlineStor.com will enable
enterprises to store and manage data over the Web with functionality similar to
that of the XtenderSolutions product suite. We expect that our customers will
realize substantial hardware and maintenance cost savings over in-house storage
systems by using this service. We currently are engaged in discussions with
various Internet service providers and application service providers regarding
OnlineStor.com. We anticipate general commercial availability of OnlineStor.com
during the second quarter of 2000.



     eMailXtender. eMailXtender is an e-mail indexing, archiving and retrieval
application that will be integrated with leading e-mail applications. It will
allow users to satisfy their legal, auditing and archiving requirements without
investing in expensive, fixed storage resources. A preliminary version of this
product, currently being implemented by Merrill Lynch, allows users to conduct
full-text searches, and archive and retrieve e-mail messages and e-commerce
transaction documents. EMailXtender is primarily based on our DiskXtender
technology, with additional development efforts focused on integrating other
technologies. We anticipate general commercial availability of this product
during the second quarter of 2000.


     Professional services and support

     We maintain a professional services division responsible for providing
customers with maintenance and technical support, consulting and training
services related to our XtenderSolutions products, which consist of:

     - analysis of a customer's requirements for data storage and management;

     - software design and implementation;

     - business process analysis and implementation;

     - product installation and upgrading;

     - custom documentation; and

     - training.


     When a customer licenses our products, we provide a 30-day support package
that includes installation, configuration and testing, access to an on-call
technical help desk, a technical support website and software updates. We also
host regularly scheduled training seminars in the Washington D.C. metropolitan
area, on the West Coast and, upon request, at a customer's site. In addition to
our own capabilities, our value-added resellers and system integrators perform
professional services for our customers.


TECHNOLOGY

     DiskXtender employs a variety of advanced technology features. DiskXtender
uses software agents that prevent the file server hard disk from running out of
free space by checking space utilization against a watermark, or threshold
setting, that can be established by the customer. Migration, space management
and retention policies are defined by the user and can be customized for any
application requirements, based, for example, on age, size or file name. Based
on these rules, DiskXtender will migrate eligible files to secondary storage. In
addition, based on defined watermarks, DiskXtender will truncate the original
file data to make space for additional data. File truncation

                                       38
<PAGE>   42
removes the original file data from the file server hard disk, leaving behind a
stub file, or place marker, freeing the space for other use.

     When the contents of a file server hard disk are viewed by an application,
such as Windows Explorer, DiskXtender displays the contents of the file server
hard disk in a way that makes the application see the original file size instead
of the stub file. When an application attempts to open the original file,
DiskXtender:

     - captures the request to open the file;

     - refers to the stub file associated with the file;

     - determines the library and storage device to which the file was migrated;
       and

     - retrieves the file from the extended storage system by copying it back to
       the original file server hard disk for use by the application that
       requested it.

DiskXtender manages all file migration based on incoming file requests and
defined storage policies. Recall of file data from secondary storage devices is
performed automatically.

     When the contents of a file server hard disk are accessed by a back-up
application, DiskXtender recognizes the back-up application and intelligently
manages the back-up data. Instead of backing up all data on the extended storage
system, it allows the back-up application to back up only the stub files, which
represent a significantly smaller amount of data. This feature reduces the time
required for back-up and also reduces the amount of data that must be backed up.

     How two of our customers have used our data storage management solutions


     CONVERTING FROM PAPER TO ELECTRONIC STORAGE AT PSINET.  PSINet, a provider
of business Internet access, has over 3,000 employees and annual revenue of more
than $560 million. With growing worldwide operations, PSINet experienced an
increasing volume of paper files generated by contracts, legal documents,
financial records and customer provisioning files. As a result of this

                                       39
<PAGE>   43

growth in paper, PSINet realized the need to increase automation of their data
storage and reduce the space and retrieval time associated with files.

     In 1998, PSINet engaged us to provide a data storage management solution
including access to critical files, document imaging and a Web-based retrieval
solution to handle the electronic contract files. We have helped PSINet convert
some areas where paper files were used to optical disk, and have installed an
optical storage management system utilizing DiskXtender, ApplicationXtender and
WebXtender for records generated by its domestic operations. We are currently
working with PSINet to extend these capabilities to many areas within their
international operations.


     AUTOMATING DATA STORAGE AT NABISCO. Nabisco, an $8.7 billion marketer of
biscuit, snack and premium food products, makes thousands of deliveries every
day to grocery stores, convenience stores and other food outlets across the
United States and in 85 other countries worldwide. With each delivery, Nabisco
issues a proof of delivery document that lists the products delivered and the
total amount due for those products.



     Nabisco had been keeping a copy of the proof of delivery on file and using
a manual system to retrieve, copy and fax proofs of delivery whenever customers
had questions or disputes on delivery. As the volume of proofs of delivery grew,
Nabisco needed to automate the process and provide improved access and
distribution.



     In 1997, Nabisco engaged us to replace their existing data storage system
with DiskXtender to effectively manage increasingly large amounts of data,
provide for easy access on the Internet and work with their high volume,
automated tape library. The new system, deployed in Nabisco's Customer Financial
Services Department, makes the proofs of delivery quickly accessible, increasing
customer service, improving access time, and cutting down on delayed payments.
Nabisco processes 120,000 images a day, and it estimates that it has processed
25 to 30 million documents since DiskXtender was installed. Another benefit for
Nabisco is that DiskXtender, with its capability to support multiple
applications, links to a second imaging system that replaces all manual
microfilm archiving systems.


SALES AND MARKETING


     We sell our products primarily through relationships with original
equipment manufacturers, value-added resellers and distributors. Our
distribution through these channels accounted for 85% of our total revenues in
1998 and 84% of our total revenues in 1999, with no single original equipment
manufacturer, value-added reseller or distributor accounting for more than 10%
of our total revenues in either year. We are also expanding our direct sales
force to provide better coverage for larger clients.



     Original Equipment Manufacturer Relationships.  We currently have more than
13 original equipment manufacturer relationships. These original equipment
manufacturers buy our products to incorporate into their own product offerings
or resell our products under their own label. We have original equipment
manufacturer relationships with Advanced Financial Solutions, Agilent
Technologies, which is a subsidiary of Hewlett-Packard, Cerner, Data General,
which is a division of EMC, FileNet, Imation, Legato Systems and StorageTek,
among others.



     Value-added Reseller and Distributor Relationships.  We currently have more
than 235 value-added reseller and distributor agreements, including agreements
with Affiliated Computer Systems, Cranel, Datalink, Electronic Data Systems,
Envision, GE Capital, IKON, Law Cypress, National Computer Systems, Optical
Laser. These resellers service North America, Europe, East Asia and


                                       40
<PAGE>   44


Latin America. Pursuant to these alliances, our value-added resellers and
distributors typically market the entire XtenderSolutions product suite,
receiving a discount on products sold.



     Direct Sales Force.  We maintain a direct sales staff with responsibilities
for pursuing and managing larger customers, as well as providing support to our
distributors, value-added resellers and original equipment manufacturers. We
have been hiring additional salespersons and expect to continue to do so.


     Marketing.  Our marketing department consists of marketing professionals
dedicated to advertising, public relations, marketing communications, events and
channel partner programs. Our marketing efforts focus on building brand
recognition and developing leads for our sales force. To achieve these
objectives, we maintain a strategic marketing program which includes the
following elements:

     - a national advertising campaign promoting the XtenderSolutions brand;

     - a comprehensive Web marketing program and website;


     - programs to enhance communication with our original equipment
       manufacturers, value-added resellers and distributors, including our
       XpertPartner conference;


     - seminars to increase the visibility of our executives and generate leads
       for our sales force;

     - participation in trade shows; and

     - direct marketing to targeted corporate customers.

COMPETITION

     We face a variety of competitors that offer products with some of our
products' features. Some potential customers may elect to internally develop
capabilities similar to those provided by our products rather than buying them
from us or another outside vendor. Although our products generally enhance
traditional data back-up capabilities offered by companies such as Veritas,
Legato Systems, Computer Associates and IBM, our products may compete against
such traditional back-up solutions when a potential customer seeks to address
its storage needs with only a data back-up solution. Furthermore, Veritas has
recently begun to offer a Windows NT-based product that competes with
DiskXtender.

     In addition, Microsoft could develop competing products. Windows 2000 will
include basic data storage management capabilities. Microsoft could compete with
us by enhancing and expanding these capabilities to offer an integrated storage
management capability within their basic operating system. This would reduce or
eliminate the need to purchase our products, which would cause our revenues and
our business to suffer.

     Many of our competitors and potential competitors have substantially
greater financial and technical resources than we do. Our competitors may
attempt to increase their presence in the data storage management software
market by acquiring or forming strategic alliances with other competitors or
business partners. This competition may cause us to lose sales and may limit the
growth of our revenues and business.

INTELLECTUAL PROPERTY

     Our products are based upon our internally developed intellectual property
and other proprietary rights. We rely on a combination of copyright, trademark
and trade secret laws, confidentiality agreements and contractual provisions to
protect our intellectual property. However, we believe that these laws and
agreements afford us only limited protection. Despite our efforts to protect our
intellectual property, unauthorized parties may infringe upon our proprietary
rights. In addition, the laws of some foreign countries do not provide as much
protection of our proprietary rights as do the laws of the United States.

EMPLOYEES


     As of December 31, 1999, we had a total of 172 employees. Of these
employees, 54 were involved in sales and marketing; 29 were involved in product
development; 46 were involved in quality assurance and product support; 25 were
involved in professional services; and 18 were involved in administrative and
corporate functions.


FACILITIES


     Our operations are headquartered in one 35,000 square foot facility in
Bethesda, Maryland that is leased under an agreement expiring on September 30,
2002. We also lease field offices in Irvine, California and Longmont, Colorado.
We believe that these facilities are suitable to meet our needs for the
foreseeable future.


LEGAL PROCEEDINGS

     We are not party to any material legal proceedings.

COMPENSATION OF DIRECTORS


     We reimburse directors for reasonable out-of-pocket expenses incurred in
attending meetings of the board of directors. We may, in our discretion, grant
stock options and other equity awards to our non-employee directors from time to
time pursuant to our stock incentive plans. In June 1999, we granted options to
purchase 10,000 shares of our common stock to each of Mr. Battista, Mr. Burton,

BOARD COMMITTEES

     The board of directors has established a compensation committee and an
audit committee. The compensation committee, which consists of Mr. Burton, Mr.
Battista and Mr. DeCesaris, reviews executive salaries, administers our bonus,
incentive compensation and stock plans and approves the salaries and other
benefits of our executive officers. In addition, the compensation committee
consults with our management regarding our pension and other benefit plans and
compensation policies and practices.

     The audit committee, which consists of Mr. Chinnici, Mr. Hebb and Mr.
DeCesaris, reviews the professional services provided by our independent
accountants, the independence of our accountants from our management, our annual
financial statements and our system of internal accounting controls. The audit
committee also reviews other matters with respect to our accounting, auditing
and financial reporting practices and procedures as it may find appropriate or
may be brought to its attention.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     We did not have a compensation committee until November 1999. Prior to that
time, the entire board of directors performed the function of a compensation
committee. No member of our compensation committee is an officer or employee. No
interlocking relationships exist between our board of directors or compensation
committee and the board of directors or compensation committee of any other
company, nor has any interlocking relationship existed in the past.

INDEMNIFICATION AGREEMENTS

     We have entered into indemnification agreements with each of our directors
and officers. Their indemnification agreements will require us to indemnify our
directors and officers to the fullest extent permitted by Delaware law.

EMPLOYMENT AGREEMENTS

     Mr. Kay serves as our chairman, president and chief executive officer
pursuant to the terms of an employment agreement dated June 9, 1999. The term of
the agreement continues until December 31, 2003. Pursuant to the terms of the
agreement, Mr. Kay's initial annual compensation consists of a base salary of
$485,000 and a bonus of at least $115,000. After the first year, Mr. Kay's
annual compensation will be determined by the board of directors. Upon
termination without cause, as defined in the agreement, Mr. Kay is entitled to
severance payments equal to (1) the greater of (a) the remaining portion of his
compensation for the remaining term of the agreement, or (b) the amount of his
then current annual salary, to be paid in monthly installments over a 12 month
period and (2) the annual bonus that would otherwise have been paid to Mr. Kay
for the fiscal year in

                                       45
<PAGE>   49

which he was terminated, to be paid in one lump sum payment within 90 days of
the date of termination. Upon termination without cause, Mr. Kay is entitled to
continue to receive the same health, disability and term life insurance benefits
as were provided prior to termination until the earlier of his employment by a
third party or December 31, 2003. Under the agreement, Mr. Kay agreed not to
compete with us during the term of his employment and for two years after his
termination. In addition, Mr. Kay agreed not to solicit our employees or
customers during the same period. However, if we terminate Mr. Kay without
cause, or he terminates his employment because we demoted him, because he is not
elected or is removed as chairman of the board or because we have relocated our
principal executive offices more than 50 miles from Bethesda, Maryland, the non-
competition and non-solicitation provisions of the agreement expire upon the
date of termination his employment.

     Mr. Caple serves as our executive vice president pursuant to the terms of
an employment agreement dated January 1, 1998, as amended. The term of the
agreement continues until December 31, 2002. Pursuant to the terms of the
agreement, Mr. Caple's annual compensation consists of a base salary of $175,000
and a bonus of at least 33.3% of his base salary. Mr. Caple's base salary will
automatically increase by 10% on January 1, 2001 and each January 1 thereafter
throughout the term of the agreement. Upon termination without cause, as defined
in the agreement, Mr. Caple is entitled to severance payments equal to the
amount of his then current annual salary, to be paid in two installments, the
first of which must be paid on the date of termination and the second of which
must be paid within 90 days of the date of termination. Mr. Caple agreed not to
compete with us during the term of his employment and for a period after the
termination of his employment equal to the lesser of two years or the length of
his employment period, if less than two years. In addition, Mr. Caple agreed not
to solicit our employees or customers during the same period.


     Mr. Kaiser serves as our chief financial officer pursuant to the terms of
an employment agreement dated May 28, 1998, as amended. The term of the
agreement continues until May 31, 2001. Pursuant to the terms of the agreement,
Mr. Kaiser's annual compensation consists of a base salary of $187,000 and a
bonus of at least 30% of his base salary. Upon termination without cause, as
defined in the agreement, Mr. Kaiser is entitled to severance payments equal to
12 months of his then current annual salary, to be paid in monthly installments
over a 12 month period, and health insurance benefits for the same period. In
addition, the agreement provides Mr. Kaiser's options will continue to vest for
a period of 12 months after termination without cause. Pursuant to the
agreement, Mr. Kaiser received an option to purchase 329,412 shares of our
common stock at a price of $1.84 per share vesting over four years, and the
right to future option grants in specified circumstances to prevent dilution of
Mr. Kaiser's shareholdings. This right terminates upon an initial public
offering. Mr. Kaiser agreed not to compete with us during the term of his
employment and for a period after the termination of his employment equal to the
lesser of two years or the length of his employment period, if less than two
years. In addition, Mr. Kaiser agreed not to solicit our employees or customers
during the same period.

(1) The potential realizable value is calculated based on the term of the option
    at the time of grant. Stock price appreciation of 5% and 10% is assumed
    pursuant to rules promulgated by the SEC and does not represent our
    prediction of our stock price performance. The potential realizable values
    at 5% and 10% appreciation are calculated by assuming that the exercise
    price on the date of grant appreciates annually at the indicated rate for
    the entire term of the option and that the


                                       47

    option is exercised at the exercise price and sold on the last day of its

     The following table sets forth information for each of the named executive
officers with respect to the value of options outstanding as of December 31,

     There was no public trading market for our common stock as of December 31,
1999. Accordingly, as permitted by the rules of the SEC, we have calculated the
value of unexercised in-the-money options at fiscal year-end on the basis of the
fair market value of our common stock as of December 31, 1999 of $12.64 per
share, as determined by the board of directors, less the aggregate exercise
price.


BENEFIT PLANS


     1998 Stock Incentive Plan and 2000 Stock Incentive Plan.  Our 1998 Stock
Incentive Plan was adopted by our Board of Directors and received stockholder
approval in August 1998. Our 2000 Stock Incentive Plan was adopted by our Board
of Directors and received stockholder approval in January 2000. Up to 4,529,412
shares and 1,000,000 shares of our common stock, subject to adjustment in the
event of stock splits and other similar events, were reserved for issuance under
the 1998 plan and 2000 plan, respectively. The board of directors has provided,
however, that no additional awards will be made under the 1998 plan after this
offering.


     The plans provide for the grant of incentive stock options intended to
qualify under Section 422 of the Internal Revenue Code, nonstatutory stock
options, restricted stock awards and other stock-based awards.


     Our officers, employees, directors, consultants and advisors and those of
our subsidiaries are eligible to receive awards under the plans. Under present
law, however, incentive stock options may only be granted to employees. Under
the 1998 plan, no participant may receive any award for more than 500,000
shares, subject to adjustment in the event of stock splits and other similar
events, in any calendar year.


     Optionees receive the right to purchase a specified number of shares of our
common stock at a specified option price, subject to the terms and conditions of
the option grant. We may grant options at an exercise price less than, equal to
or greater than the fair market value of our common stock on the date of grant.
Under present law, incentive stock options and options intended to qualify as
performance-based compensation under Section 162(m) of the Internal Revenue Code
may not be granted at an exercise price less than the fair market value of the
common stock on the date of grant, or less than 110% of the fair market value in
the case of incentive stock options granted to optionees holding more than 10%
of our voting power. The plans permit our board of directors to determine

                                       48
<PAGE>   52

how optionees may pay the exercise price of their options, including by cash,
check or in connection with a "cashless exercise" through a broker, by surrender
to us of shares of common stock, by delivery to us of a promissory note, or by
any combination of the permitted forms of payment.

     Our board of directors administers the plans. Our board of directors has
the authority to adopt, amend and repeal the administrative rules, guidelines
and practices relating to the plans and to interpret their provisions. It may
delegate authority under the plans to one or more committees of the board of
directors and, in limited circumstances, to one or more of our executive
officers. Our board of directors has authorized the compensation committee to
administer the plans, including the granting of options to our executive
officers. Subject to any applicable limitations contained in the plans, our
board of directors, our compensation committee or any other committee or
executive officer to whom our board of directors delegates authority, as the
case may be, selects the recipients of awards and determines the:

     - number of shares of common stock covered by options and the dates upon
       which such options become exercisable;

     - exercise price of options;

     - duration of options; and

     - number of shares of common stock subject to any restricted stock or other
       stock-based awards and the terms and conditions of such awards, including
       the conditions for repurchase, issue price and repurchase price.

     In the event of a merger, liquidation or other acquisition event, our board
of directors must provide that all outstanding options or other stock-based
awards under the plans be assumed or substituted for by the acquiror. If any of
these events constitutes a change in control, the assumed or substituted options
will be immediately exercisable in full upon the occurrence of the acquisition
event if the holders such options has been employed by us for more than one year
prior to the change in control.

     No award may be granted under the 1998 plan after August 2008 or under the
2000 plan after January 2010, but the vesting and effectiveness of awards
granted before those dates may extend beyond those dates. Our board of directors
may at any time amend, suspend or terminate the 1998 plan or the 2000 plan,
except that, under the 1998 plan, no award granted after an amendment of the
plan and designated as subject to Section 162(m) of the Internal Revenue Code by
our board of directors shall become exercisable, realizable or vested, to the
extent such amendment was required to grant such award, unless and until such
amendment is approved by our stockholders.


     2000 Employee Stock Purchase Plan.  Our 2000 Employee Stock Purchase Plan
was adopted by our board of directors and received stockholder approval in
January 2000. The purchase plan authorizes the issuance of up to a total of
600,000 shares of our common stock to participating employees.


     All of our employees, including our directors who are employees, and all
employees of any participating subsidiaries, whose customary employment is more
than 20 hours per week and for more than five months in any calendar year, are
eligible to participate in the purchase plan. Employees who would immediately
after the grant own 5% or more of the total combined voting power or value of
our stock or that of any subsidiary are not eligible to participate.


     On the first day of a designated payroll deduction period, or offering
period, we will grant to each eligible employee who has elected to participate
in the purchase plan an option to purchase shares of our common stock as
follows: the employee may authorize up to 10% of his or her base pay to be
deducted by us from his or her base pay during the offering period. On the last
day of this offering period, the employee is deemed to have exercised the
option, at the option exercise price, to

                                       49
<PAGE>   53


the extent of accumulated payroll deductions. Under the terms of the purchase
plan, the option price is an amount equal to 85% of the average market price, as
defined in the purchase plan, per share of our common stock on either the first
day or the last day of the offering period, whichever is lower. The first
offering period under the purchase plan will commence on the date on which
trading of our common stock commences on the Nasdaq National Market, with the
option price on the first day of such offering period equivalent to the initial
public offering price. In no event may an employee purchase in any one-year
period a number of shares that exceeds the number of shares determined by
dividing $25,000 by the average market price of a share of our common stock on
the commencement date of the offering period. Our compensation committee may, in
its discretion, choose an offering period of 12 months or less for each offering
and choose a different offering period for each offering.


     An employee who is not a participant on the last day of the offering period
is not entitled to exercise any option, and the employee's accumulated payroll
deductions will be refunded. An employee's rights under the purchase plan
terminate upon voluntary withdrawal from the purchase plan at any time, or when
the employee ceases employment for any reason, except that upon termination of
employment because of death, the employee's beneficiary has a right to elect to
exercise the option to purchase the shares which the accumulated payroll
deductions in the participant's account would purchase at the date of death.

     Because participation in the purchase plan is voluntary, we cannot now
determine the number of shares of our common stock to be purchased by any of our
current executive officers, by all of our current executive officers as a group
or by our non-executive employees as a group.

     401(k) Plan.  In May 1996, we adopted an employee savings and retirement
plan qualified under Section 401 of the Internal Revenue Code and covering all
of our employees. Pursuant to the 401(k) plan, employees may elect to reduce
their current compensation by up to the statutorily prescribed annual limit and
have the amount of such reduction contributed to the 401(k) plan. We may make
matching or additional contributions to the 401(k) plan in amounts to be
determined annually by our board of directors.

1999, 10% until June 9, 2000 and 12% thereafter until maturity. By their terms,
these notes will become immediately due and payable upon the closing of this

     Repurchase of shares from former stockholder.  In March 1998, we entered
into a stock purchase agreement with Eugene S. Sandler, a former stockholder of
ours who then held 39.6% of our common stock. Under this agreement, we purchased
all of Mr. Sandler's shares of our common stock for a purchase price of
$6,000,000 in cash and a promissory note in the principal amount of $5,500,000
bearing interest at a rate of 10% per year. Under the terms of the promissory
note, we are obligated to pay Mr. Sandler all outstanding principal and interest
within 60 days of the closing of this offering. As of January 31, 2000, we have
paid Mr. Sandler $2,080,000 and owe $4,269,659 in principal and $23,218 in
interest.


     Contribution to capital by OTG Sales, Inc. stockholders.  Mr. Kay, Mr.
Caple and Alexandra Kay were all the stockholders of OTG Sales, Inc., an
affiliate of ours. In December 1999, they contributed all their shares of
capital stock of OTG Sales, Inc. to us as a contribution to capital, making OTG
Sales, Inc. our wholly owned subsidiary. We did not pay any consideration for
the contributed shares.

     Loans from principal stockholder.  In March 1992, we entered into a loan
agreement and related promissory note with Mr. Kay in order to secure working
capital for our operations. The loan

agreement and the promissory note originally provided for Mr. Kay to make
unsecured loans to us up to a maximum principal amount of $650,000. On December
1, 1993, the promissory note was amended to increase the maximum principal
amount of the promissory note to $700,000. On December 1, 1994, the promissory
note was amended again to increase the maximum principal amount of the
promissory note to $1,000,000 and to make the promissory note payable upon
demand. Amounts that we borrow under the loan agreement bear simple interest at
a rate of 8% per year. Mr. Kay may require us to provide security for
outstanding and future loans at any time. As of January 31, 2000, we owed Mr.
Kay $472,536 as a result of borrowings and accrued interest under this
arrangement.



     In addition, on June 16, 1998, we borrowed an aggregate principal amount of
$1,500,000 from Mr. Kay in order to secure working capital for our operations
pursuant to two promissory notes. These notes earn 8% interest which is payable
quarterly. The principal amount of these notes is due and payable upon the
earlier of December 16, 2000 or 60 days after the closing of this offering, a
qualified merger or a sale of substantially all of our assets. These notes are
subordinated to our senior subordinated notes, our subordinated convertible
notes and our credit facility with PNC Bank, collectively our senior
indebtedness. We can not make any payments of principal or interest on these
notes if we are in default under our senior indebtedness. As of January 31,
2000, we owed Mr. Kay $1,510,000 under these notes.


     Guarantee of our obligation by principal stockholder.  As a condition to
entering into a loan agreement with us, PNC Bank required Mr. Kay to enter into
an escrow agreement, dated July 22, 1999, with us, PNC Bank and Bankers Trust,
as escrow agent. Pursuant to this escrow agreement, Mr. Kay deposited marketable
securities held by him with the escrow agent as security for payments to be made
by us under the promissory note we issued to Mr. Sandler, as described above. If
we fail to make payments under this promissory note when due, or if we become
obligated to make a balloon payment under the terms of the promissory note, the
escrow agreement provides that PNC Bank may direct the escrow agent to sell Mr.
Kay's shares and apply the proceeds of the sale to the required payment. The
escrow agreement terminates when we have paid in full all of our obligations to
PNC Bank under the loan agreement.


     Stock Sales by Principal Stockholder.  During the period beginning June
1998 through January 2000, Mr. Kay sold an aggregate amount of 795,826 shares of
our common stock to four members of our board of directors at a per share price
ranging from $1.84 to $5.50. During the same period, Mr. Kay issued convertible
promissory notes to ABS Capital Partners II, L.P. and Michael Murray, which will
convert at the closing of this offering into an aggregate amount of 1,962,190
and 1,000 shares of our common stock, respectively. The conversion price of
these convertible notes ranges from $2.75 to $5.50 per share of common stock.
Additionally, in October 1999, Mr. Kay sold 40,000 shares of our common stock at
a per share price of $2.75 to Mr. Kaiser, our chief financial officer.



     Option grants to non-employee directors and executive officers.  In June
1999, we granted options to purchase 10,000 shares of common stock at an
exercise price of $2.75 per share under our 1998 stock incentive plan to each of
Mr. Battista, Mr. Burton, Mr. Chinnici, Mr. DeCesaris and Mr. Hebb, our
non-employee directors. These options vested upon grant. In October 1998, we
granted Mr. Kaiser, our chief financial officer, an option to purchase 329,412
shares of common stock at an exercise price of $1.84 per share under our 1998
stock incentive plan. This option vests over a four year period. In September
1999, we granted Mr. Kaiser, an option to purchase 100,000 shares of common
stock at an exercise price of $2.75 per share under our 1998 stock incentive
plan. This option vests quarterly over a three year period. In January 1999, we
granted Mr. Caple, our executive vice president, an option to purchase 200,000
shares of common stock at an exercise price of $1.84 per share under our 1998
stock incentive plan. This option vests quarterly over a three year period.

     Sale of stock to our executive vice president.  In January 1997, we sold
269,254 shares of common stock to F. William Caple, our executive vice
president, secretary and director, for an aggregate purchase price of $102,698.
Mr. Caple paid for these shares with a promissory note bearing 8% interest per
annum that becomes due January 1, 2002. As of January 31, 2000, the outstanding
balance of Mr. Caple's note to us was $122,315.


     Indemnification agreements.  We have entered into indemnification
agreements with each of our directors and officers. Such indemnification
agreements will require us to indemnify our directors and officers to the
fullest extent permitted by Delaware law.


     Our board of directors has adopted the policy that all future transactions,
including loans between us and our officers, directors, principal stockholders
and their affiliates, will be approved by a majority of the board of directors,
including a majority of the independent and disinterested outside directors on
the board of directors, and will be on terms no less favorable to us than could
be obtained from unaffiliated third parties.

more than 5% of the outstanding shares of our common stock, (2) each of our
directors and the named executive officers, and (3) all of our directors and
executive officers as a group.



     One of our stockholders, Mr. Kay, has granted to the underwriters an option

     The number of shares of common stock deemed outstanding prior to this
offering includes 20,476,188 shares of common stock outstanding as of January
31, 2000. This table gives effect to the conversion of all outstanding

subject to options held by that person that are currently exercisable or
exercisable within 60 days of January 31, 2000. The shares issuable under those
options are treated as if they were outstanding for computing the percentage
ownership of the person holding those options but are not treated as if they
were outstanding for the purposes of computing the percentage ownership of any
other person. Unless otherwise indicated below, to our knowledge, all persons
named in the table have sole voting and investment power with respect to their
shares of common stock, except to the extent authority is shared by spouses

                          DESCRIPTION OF CAPITAL STOCK


     On the closing of this offering, our authorized capital stock will consist
of 65,000,000 shares of common stock, $.01 par value per share, and 5,000,000
shares of preferred stock, $.01 par value per share. The following is a summary
of the material features of our capital stock. For more detail, please see our
amended and restated certificate of incorporation and our amended and restated
by-laws to be effective after the closing of this offering, filed as exhibits to
the registration statement of which this prospectus is a part.


COMMON STOCK


     As of February 7, 2000, after giving effect to the conversion of the
outstanding convertible notes issued by us, there were 20,476,188 shares of
common stock outstanding held by 19 stockholders of record. Based upon the
number of shares outstanding as of that date and after giving effect to the
issuance of the shares of common stock offered by us in this offering, there
will be 24,476,188 shares of common stock outstanding upon the closing of this
offering.


     Holders of common stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Directors are elected by a plurality of the votes of the shares present
in person or by proxy at the meeting and entitled to vote in such election.
Subject to preferences that may be applicable to any outstanding preferred
stock, holders of common stock are entitled to receive ratably such dividends,
if any, as may be declared by the board of directors out of funds legally
available to pay dividends. Upon our liquidation, dissolution or winding up, the
holders of common stock are entitled to receive ratably all assets after the
payment of our liabilities, subject to the prior rights of any outstanding
preferred stock. Holders of the common stock have no preemptive, subscription,
redemption or conversion rights. They are not entitled to the benefit of any
sinking fund. The outstanding shares of common stock are, and the shares offered
by us in this offering will be, when issued and paid for, validly issued, fully
paid and nonassessable. The rights, powers, preferences and privileges of
holders of common stock are subject to the rights of the holders of shares of
any series of preferred stock which we may designate and issue in the future.

PREFERRED STOCK


     The board of directors is authorized, subject to any limitations prescribed
by law, without further stockholder approval, to issue up to an aggregate of
5,000,000 shares of preferred stock. The preferred stock may be issued in one or
more series and on one or more occasions. Each series of preferred stock shall
have such number of shares, designations, preferences, voting powers,
qualifications and special or relative rights or privileges as the board of
directors may determine. These rights and privileges may include, among others,
dividend rights, voting rights, redemption provisions, liquidation preferences,
conversion rights and preemptive rights. Our stockholders have granted the board
of directors authority to issue the preferred stock in order to eliminate delays
associated with a stockholder vote on specific issuances. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could adversely affect the
voting power or other rights of the holders of common stock. In addition, the
issuance of preferred stock could make it more difficult for a third party to
acquire us, or discourage a third party from attempting to acquire us.

DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS; ANTI-TAKEOVER EFFECTS

     We are subject to the provisions of Section 203 of the General Corporation
Law of Delaware. Section 203 prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. A "business combination" includes mergers, consolidations,
asset sales and other transactions involving OTG and an interested stockholder.
In general, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, 15% or more of
the corporation's voting stock.

     Our amended and restated certificate of incorporation and amended and
restated by-laws to be effective on the closing of this offering provide that:

     - the board of directors be divided into three classes, as nearly equal in
       size as possible, with staggered three-year terms;

     - directors may be removed only for cause by the affirmative vote of the
       holders of at least 75% of the shares of our capital stock entitled to
       vote;

     - any vacancy on the board of directors, however occurring, including a
       vacancy resulting from an enlargement of the board, may only be filled by
       vote of a majority of the directors then in office.

     The classification of the board of directors and the limitations on the
removal of directors and filling of vacancies could have the effect of making it
more difficult for a third party to acquire us, which could have the effect of
discouraging a third party from attempting to do so.

     Our amended and restated certificate of incorporation and amended and
restated by-laws also provide that, after the closing of this offering:

     - any action required or permitted to be taken by the stockholders at an
       annual meeting or special meeting of stockholders may only be taken if it
       is properly brought before such meeting and may not be taken by written
       action in lieu of a meeting.

     - special meetings of the stockholders may only be called by the chairman
       of the board of directors, the president, or by the board of directors.
       Our amended and restated by-laws provide that, in order for any matter to
       be considered "properly brought" before a meeting, a stockholder must
       comply with requirements regarding advance notice to us. These provisions
       could delay until the next stockholders' meeting stockholder actions
       which are favored by the holders of a majority of our outstanding voting
       securities. These provisions may also discourage another person or entity
       from making a tender offer for our common stock, because such person or
       entity, even if it acquired a majority of our outstanding voting
       securities, would be able to take action as a stockholder (such as
       electing new directors or approving a merger) only at a duly called
       stockholders meeting, and not by written consent.

     Delaware's corporation law provides generally that the affirmative vote of
a majority of the shares entitled to vote on any matter is required to amend a
corporation's certificate of incorporation or by-laws, unless a corporation's
certificate of incorporation or by-laws, as the case may be, requires a greater
percentage. Our amended and restated certificate of incorporation requires the
affirmative vote of the holders of at least 75% of the shares of our capital
stock entitled to vote to amend or repeal any of the foregoing provisions of our
amended and restated certificate of incorporation. Generally,

                                       57
<PAGE>   61

our amended and restated by-laws may be amended or repealed by a majority vote
of the board of directors or the holders of a majority of the shares of our
capital stock issued and outstanding and entitled to vote. To amend our amended
and restated by-laws regarding special meetings of stockholders, written actions
of stockholders in lieu of a meeting, and the election, removal and
classification of members of the board of directors requires the affirmative
vote of the holders of at least 75% of the shares of our capital stock entitled
to vote. The stockholder vote would be in addition to any separate class vote
that might in the future be required pursuant to the terms of any series
preferred stock that might be outstanding at the time any such amendments are
submitted to stockholders.

LIMITATION OF LIABILITY AND INDEMNIFICATION

     Our amended and restated certificate of incorporation provides that our
directors and officers shall be indemnified by us to the fullest extent
authorized by Delaware law. This indemnification would cover all expenses and
liabilities reasonably incurred in connection with their services for or on
behalf of us. In addition, our amended and restated certificate of incorporation
provides that our directors will not be personally liable for monetary damages
to us for breaches of their fiduciary duty as directors, unless they violated
their duty of loyalty to us or our stockholders, acted in bad faith, knowingly
or intentionally violated the law, authorized illegal dividends or redemptions
or derived an improper personal benefit from their action as directors.

TRANSFER AGENT AND REGISTRAR


     The transfer agent and registrar for the common stock is BankBoston, N.A.

</TABLE>



     In general, under Rule 144, a person, including an affiliate, who has
beneficially owned shares for at least one year is entitled to sell, within any
three-month period, a number of such shares that does not exceed the greater of
(1) one percent of the then outstanding shares of common stock, or approximately
244,761 shares immediately after this offering, or (2) the average weekly
trading volume in the common stock in the over-the-counter market during the
four calendar weeks preceding the date on which notice of such sale is filed,
provided specified requirements concerning availability of public information,
manner of sale and notice of sale have been satisfied. In addition, our
affiliates must comply with the restrictions and requirements of Rule 144, other
than the one-year holding period requirement, in order to sell shares of common
stock which are not restricted securities.


     Under Rule 144(k), a person who is not an affiliate and has not been an
affiliate for at least three months prior to the sale and who has beneficially
owned shares for at least two years may resell these shares without compliance
with the foregoing requirements. In meeting the one- and two-year holding
periods described above, a holder of shares can include the holding periods of a
prior owner who was not an affiliate. The one- and two-year holding periods
described above do not begin to run until the full purchase price or other
consideration is paid by the person acquiring the shares from the issuer or an
affiliate. Rule 701 provides that currently outstanding shares of common stock
acquired under our employee compensation plans may be resold beginning 90 days
after the date of this prospectus (1) by persons, other than affiliates, subject
only to the manner of sale provisions of Rule 144, and (2) by affiliates under
Rule 144 without compliance with its one-year minimum holding period, subject to
certain limitations.

LOCK-UP AGREEMENTS

     Subject to limited exceptions, we and our executive officers and directors
have agreed that, without the prior written consent of Credit Suisse First
Boston Corporation, none of us will, during the period ending 180 days after the
date of this prospectus, (1) offer, pledge, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant to purchase, lend, or otherwise transfer or dispose
of, directly or indirectly, any shares of common stock or any securities
convertible into or exercisable or exchangeable for common stock (regardless of
whether such shares or any such securities are then owned by such person or are
thereafter acquired), or (2) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of the common stock, regardless of whether any such transactions
described in clauses (1) or (2) are to be settled by delivery of such common
stock or such other securities, in cash or otherwise. In addition, for a period
of 180 days from the date of this prospectus, except as required by law, we have
agreed that our board of directors will not consent to any offer for sale, sale

     Under the terms and subject to the conditions contained in an underwriting
agreement dated           , 2000, we have agreed to sell to the underwriters
named below, for whom Credit Suisse First Boston Corporation, Deutsche Bank
Securities Inc., SG Cowen Securities Corporation and Friedman, Billings, Ramsey
& Co., Inc. are acting as representatives, the following respective numbers of
shares of common stock:

</TABLE>


     The underwriting agreement provides that the underwriters are obligated to
purchase all the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults the
purchase commitments of non-defaulting underwriters may be increased or the
offering of common stock may be terminated.


     The selling stockholder, Richard A. Kay, has granted to the underwriters a
30-day option to purchase on a pro rata basis up to 600,000 additional shares
from the selling stockholder at the initial public offering price less the
underwriting discounts and commissions. The option may be exercised only to
cover any over-allotments of common stock. Underwriters' discounts and
commissions represent the public offering price of the common stock less the
amount the underwriters pay us for the common stock.



     The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $     per share. The
underwriters and selling group members may allow a discount of $     per share
on sales to other broker/dealers. After the initial public offering, the public
offering price and concession and discount to broker/dealers may be changed by
the underwriters. A broker is any person engaged in the business of effecting
transactions in securities for the accounts of others, but does not include a
bank. A dealer is any person engaged in the business of buying and selling
securities for his own account, through a broker or otherwise, but does not
include a bank. A selling group member is a member of the selling syndicate.



     The following table summarizes the compensation and estimated expenses we
will pay.

     In June 1998, we sold an aggregate principal amount of $9,546 in
subordinated convertible notes and an aggregate amount of $2,727 in senior
subordinated notes to Michael Murray. Mr. Murray is a principal of Deutsche Banc
Alex. Brown, Inc., one of the managing underwriters in this offering.


     Friedman, Billings, Ramsey & Co., Inc., one of the managing underwriters in
this offering, has agreed to provide us, in its ordinary course of business,
financial advisory services over the next 12 months for a fee of $160,000.


     The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares of common stock being offered by us and the
selling stockholder.


     We, the directors, officers and other stockholders have agreed that we will
not offer, sell, contract to sell, pledge or otherwise dispose of, directly or
indirectly, or file with the SEC a registration statement under the Securities
Act relating to, any additional shares of our common stock or securities
convertible into or exchangeable or exercisable for any of our common stock, or
publicly disclose the intention to make any such offer, sale, pledge,
disposition or filing, without the prior written consent of Credit Suisse First
Boston Corporation for a period of 180 days after the date of this prospectus,
except in our case grants of stock options or issuances of stock pursuant to our
employee stock plans described in this prospectus or issuances pursuant to the
exercise of stock options or warrants outstanding on the date hereof.



     The underwriters have reserved for sale, at the initial public offering
price up to 400,000 shares of the common stock for employees, directors and
certain other persons associated with us who have expressed an interest in
purchasing common stock in the offering. The number of shares available for sale
to the general public in the offering will be reduced to the extent such persons
purchase such reserved shares. Any reserved shares not so purchased will be
offered by the underwriters to the general public on the same terms as the other
shares.


     We and the selling stockholder have agreed to indemnify the underwriters
against liabilities under the Securities Act, or contribute to payments which
the underwriters may be required to make in that respect.

     We have made application to list the shares of common stock on The Nasdaq
Stock Market's National Market.


     Prior to this offering, there has been no public market for our common
stock. The initial public offering price and the underwriters' compensation will
be determined by negotiation between us and the underwriters. The principal
factors to be considered in determining the public offering price will include:
the information set forth in this prospectus and otherwise available to the
underwriters; the history and the prospects for the industry in which we
compete; the ability of our management; the prospects for our future earnings;
the present state of our development and our current financial condition; the
general condition of the securities markets at the time of this offering; and
the recent market prices of, and the demand for, publicly traded common stock of
generally comparable companies. Underwriters' compensation will be determined
based upon what is customary for offerings of securities by companies in our
industry.


     The representatives, may engage in over-allotment, stabilizing
transactions, syndicate covering transactions, penalty bids and "passive" market
making in accordance with Regulation M under the Securities Exchange Act of
1934.

     - Over-allotment involves syndicate sales in excess of the offering size,
       which creates a syndicate short position.

     - Stabilizing transactions permit bids to purchase the underlying security
       so long as the stabilizing bids do not exceed a specified maximum.
       Syndicate covering transactions involve

                                       62
<PAGE>   66

       purchases of the common stock in the open market after the distribution
       has been completed in order to cover syndicate short positions.

     - Penalty bids permit the representatives to reclaim a selling concession
       from a syndicate member when the common stock originally sold by such
       syndicate member is purchased in a stabilizing transaction or a syndicate
       covering transaction to cover syndicate short positions.

     - In "passive" market making, market makers in the common stock who are
       underwriters or prospective underwriters may, subject to certain
       limitations, make bids for or purchases of the common stock until the
       time, if any, at which a stabilizing bid is made.

These stabilizing transactions, syndicate covering transactions and penalty bids
may cause the price of the common stock to be higher than it would otherwise be
in the absence of these transactions. These transactions may be effected on The
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

     The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we and the selling
shareholder prepare and file a prospectus with the securities regulatory
authorities in each province where trades of common stock are effected.
Accordingly, any resale of the common stock in Canada must be made in accordance
with applicable securities laws which will vary depending on the relevant
jurisdiction, and which may require resales to be made in accordance with
available statutory exemptions or pursuant to a discretionary exemption granted
by the applicable Canadian securities regulatory authority. Purchasers are
advised to seek legal advice prior to any resale of the common stock.

REPRESENTATIONS OF PURCHASERS

     Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us, the selling shareholders and the
dealer from whom such purchase confirmation is received that


     - such purchaser is entitled under applicable provincial securities laws to
       purchase such common stock without the benefit of a prospectus qualified
       under such securities laws,



     - where required by law, that such purchaser is purchasing as principal and
       not as agent, and



     - such purchaser has reviewed the text above under "Resale Restrictions."


RIGHTS OF ACTION (ONTARIO PURCHASERS)

     The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

ENFORCEMENT OF LEGAL RIGHTS

     All of the issuer's directors and officers as well as the experts named
herein and the selling shareholder may be located outside of Canada and, as a
result, it may not be possible for Canadian purchasers to effect service of
process within Canada upon the issuer or such persons. All or a

                                       63
<PAGE>   67

substantial portion of the assets of the issuer and such persons may be located
outside of Canada and, as a result, it may not be possible to satisfy a judgment
against the issuer or such persons in Canada or to enforce a judgment obtained
in Canadian courts against such issuer or persons outside of Canada.

NOTICE TO BRITISH COLUMBIA RESIDENTS

     A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one such report
must be filed in respect of common stock acquired on the same date and under the
same prospectus exemption.

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.

                                    EXPERTS


     The consolidated financial statements and schedule of OTG Software, Inc.
and subsidiary as of December 31, 1998 and 1999, and for each of the years in
the three-year period ended December 31, 1999 have been included in this
prospectus and elsewhere in the registration statement in reliance upon the
reports of KPMG LLP, independent certified public accountants, appearing
elsewhere herein, and upon the authority of said firm as experts in accounting
and auditing.


                               CHANGE OF AUDITORS


     In July 1999, we dismissed our independent auditors, Grant Thornton, LLP,
and retained KPMG LLP to act as our independent public accountants. Grant
Thornton, LLP had been our independent accountants since March 1997. In
connection with Grant Thornton, LLP's audit of the combined financial statements
for the years ended December 31, 1996 and 1997, and in connection with the
subsequent period up to July 1999, there were no disagreements with Grant
Thornton, LLP on any matters of accounting principles or practices, financial
statements disclosure or auditing scope or procedures, nor any reportable
events. Grant Thornton, LLP's report on our combined financial statements for
the years ended December 31, 1996 and 1997 contained no adverse opinion or
disclaimer of opinion and was not modified or qualified as to uncertainty, audit
scope or accounting principles. The decision to change auditors was approved by
our board of directors. We have provided Grant Thornton, LLP with a copy of the
disclosure contained in this section of the prospectus.

                          INDEPENDENT AUDITORS' REPORT

Board of Directors
OTG Software, Inc.:


     We have audited the accompanying consolidated balance sheets of OTG
Software, Inc. and subsidiary (the "Company") as of December 31, 1998 and 1999,
and the related consolidated statements of operations, stockholders' deficit,
and cash flows for each of the years in the three-year period ended December 31,
1999. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits.


     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.


     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of OTG
Software, Inc. and subsidiary as of December 31, 1998 and 1999, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1999, in conformity with generally accepted accounting
principles.

On December 30, 1999, in connection with the Company's planned initial public
offering ("IPO"), the stock of OTG Sales was contributed to OTG Software for no
consideration. The combination has been accounted for at historical cost. The
accompanying financial statements have been retroactively restated to give
effect to the consolidation as if it had occurred prior to January 1, 1997.



     All significant intercompany balances and transactions have been eliminated
in consolidation.


(c)  REVENUE RECOGNITION

     Revenues are generated from licensing software and providing services,
including maintenance and technical support, training and consulting.

     In October 1997, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 97-2, Software Revenue
Recognition. Subsequently, in March 1998 and December 1998, the AICPA issued SOP
98-4 and SOP 98-9, respectively, which defer until the Company's fiscal year
beginning January 1, 2000, the application of several paragraphs and examples in
SOP 97-2 that limit the definition of vendor specific objective evidence
("VSOE") for determining fair value of various elements in a multiple element
arrangement. The provisions of SOP 97-2 have been applied to transactions
entered into beginning January 1, 1998. Prior to 1998, the Company's revenue
recognition policy was in accordance with the preceding authoritative guidance
provided by SOP No. 91-1, Software Revenue Recognition. The adoption of SOP 97-2
did not have a material impact on the Company's financial statements. Further,
management of the Company does not believe that the adoption of the remaining
portions of SOP 97-2, which were deferred by SOP 98-4 and SOP 98-9, will have a
material impact on the Company's financial statements.

     Software license revenues consist of fees for licenses of the Company's
software products. The Company sells its software products primarily through
distributors and resellers. In some cases, the Company provides extended payment
terms to certain distributors and resellers. For arrangements in which payment
terms are within six months, the Company recognizes the revenue when the
agreement is signed, the arrangement fee is fixed and determinable, delivery of
the software has

                                       F-7

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


occurred, and collectibility of the fee is considered probable. For arrangements
in which payment terms extend beyond six months, the Company recognizes revenue
when payment by the customer is made or becomes due, if all other revenue
recognition criteria have been met.

     Services revenues consist of maintenance and technical support, training
and consulting. Revenues from maintenance and technical support, which consists
of unspecified when-and-if-available product updates and customer telephone
support services, are recognized ratably over the term of the service period.
Other services revenues are recognized as the related services are being
provided.

(d)  COST OF REVENUES

     The cost of software license revenues consists primarily of royalties,
media, manuals and distribution costs. The cost of services revenues consists
primarily of personnel-related costs.

(e)  SOFTWARE DEVELOPMENT COSTS


     Software development costs are accounted for in accordance with Statement
of Financial Accounting Standards No. 86, Accounting for the Costs of Computer
Software to be Sold, Leased or Otherwise Marketed. Under the standard,
capitalization of software development costs begins upon the establishment of
technological feasibility, subject to net realizable value considerations. To
date, the period between achieving technological feasibility and the general
availability of such software has been short; therefore, software development
costs qualifying for capitalization have been immaterial. Accordingly, the
Company has not capitalized any software development costs and has charged all
such costs to research and development expense. Research and development costs
are expensed as incurred.


(f)  PROPERTY AND EQUIPMENT

     Depreciation is provided for in amounts sufficient to relate the cost of
depreciable assets to operations over their estimated service lives, on a
straight-line basis. The estimated service lives used in determining
depreciation are three years for computer hardware and software, and seven years
for furniture and equipment. Leasehold improvements are amortized over the
shorter of the useful life of the asset, generally four years, or the lease
term.

     Maintenance and repairs are charged to expense as incurred; additions and
betterments are capitalized. Upon retirement or sale, the cost and related
accumulated depreciation of the disposed assets are removed and any resulting
gain or loss is credited or charged to operations.

(g)  RECOVERY OF LONG-LIVED ASSETS

     The Company's policy is to review its long-lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount
may not be recoverable. The Company recognizes an impairment loss when the sum
of the expected future cash flows is less than the carrying amount of the asset.
The measurement of the impairment losses to be recognized is based upon the
difference between the fair value and the carrying amount of the assets.

(h)  INCOME TAXES

     OTG Software and OTG Sales each have elected to be treated as an S
corporation under the provisions of the Internal Revenue Code. Under those
provisions, the Company does not pay federal

                                       F-8
<PAGE>   77

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


or state corporate income taxes on its taxable income. Instead, the stockholders
are liable for federal and state income taxes on the Company's taxable income.

(i)  CASH AND CASH EQUIVALENTS

     The Company considers all highly liquid investments purchased with an
original maturity of 90 days or less to be cash equivalents. The carrying values
of cash equivalents approximate fair values. Cash equivalents include overnight
repurchase agreements.

(j)  ADVERTISING COSTS


     Advertising costs are expensed as incurred. Total advertising expense was
$584,000, $378,000 and $522,000, respectively, for the years ended December 31,
1997, 1998, and 1999.


(k)  CONCENTRATION OF CREDIT RISK


     Financial instruments that potentially subject the Company to credit risk
include accounts receivable and cash balances with financial institutions. The
Company extends credit to its customers on an unsecured basis in the normal
course of business and maintains an allowance for potential losses when
identified. Included in accounts receivable at December 31, 1999 is
approximately $1,626,000 due from two customers under arrangements with extended
payment terms. The amounts under these arrangements are all due within six
months from December 31, 1999. There were no significant amounts with extended
payment terms due at December 31, 1998.



     Cash balances in financial institutions are insured by the Federal Deposit
Insurance Corporation up to $100,000. Uninsured balances at December 31, 1998
and 1999 were $337,000 and $2,294,000, respectively. The Company has not
experienced any losses in such accounts and believes it is not exposed to any
significant credit risk on cash.


(l)  ESTIMATES

     In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements, and
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.


(m)  PRO FORMA STATEMENT OF OPERATIONS AND BALANCE SHEET DATA, AND NET INCOME
     (LOSS) PER SHARE (UNAUDITED)



     In connection with the Company's planned initial public offering of common
stock, the Company intends to convert to a Subchapter C corporation under the
Internal Revenue Code. Accordingly, the accompanying pro forma statement of
operations data has been prepared as if the Company were treated as a Subchapter
C corporation for federal and state income tax purposes from January 1, 1997.
The accompanying pro forma balance sheet data has been prepared giving effect to
the conversion of all outstanding convertible debt and related accrued interest
(note 6) into common stock immediately prior to the closing of the initial
public offering.


     The Company computes net income (loss) per share in accordance with SFAS
No. 128, "Earnings Per Share," and SEC Staff Accounting Bulletin ("SAB") No. 98.
Under the provisions of SFAS No. 128 and SAB No. 98, pro forma basic net income
(loss) per share is computed by

                                       F-9
<PAGE>   78

                       OTG SOFTWARE, INC. AND SUBSIDIARY


           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)



dividing the pro forma net income (loss) available to common stockholders for
the period by the weighted average number of common shares outstanding during
the period. Pro forma diluted net income (loss) per share is computed by
dividing the pro forma net income (loss) for the period by the weighted average
number of common and dilutive common stock equivalent shares outstanding during
the period.


     Certain shares issuable upon the conversion of convertible debt and stock
options and warrants outstanding were not included in the pro forma diluted net
income (loss) per share as such amounts would be anti-dilutive.


(n)  STOCK SPLIT



     On January 18, 2000, the Board of Directors of the Company approved a
2-for-1 stock split of the Company's common stock. All share, per share and
conversion amounts relating to common stock, stock options and stock purchase
warrants included in the accompanying consolidated financial statements have
been retroactively adjusted to reflect the stock split.


(o)  STOCK-BASED COMPENSATION

     The Company accounts for equity-based compensation arrangements in
accordance with the provisions of Accounting Principles Board ("APB") Opinion
No. 25, "Accounting for Stock Issued to Employees," and related interpretations,
and complies with the disclosure provisions of SFAS No. 123, "Accounting for
Stock-Based Compensation." Under APB Opinion No. 25, compensation expense is
based upon the difference, if any, on the date of grant, between the fair value
of the Company's stock and the exercise price. All equity-based awards to
non-employees are accounted for at their fair value in accordance with SFAS No.
123.

(p)  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of cash and cash equivalents, accounts receivable,
accounts payable, and short-term debt approximates the fair values due to the
short-term nature of these instruments. The carrying value of the convertible
subordinated debt and the senior subordinated debt approximate fair value based
on borrowing rates currently available for financial instruments with similar
characteristics and maturities. These estimates are subjective in nature and
involve uncertainties and matters of significant judgment and, therefore, cannot
be determined with precision. Changes in assumptions could significantly affect
the estimates.

(q)  RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting for
Derivative Instruments and Hedging Activities." The new standard establishes
accounting and reporting standards for derivative instruments embedded in other
contracts and for hedging activities. This statement, as amended, is effective
for all fiscal quarters beginning after June 15, 2000. The Company does not
expect SFAS No. 133 to have a material affect on its financial position or
results of operations.

     In December 1999, the Securities and Exchange Commission ("SEC") issued SAB
No. 101-Revenue Recognition in Financial Statements. This SAB expresses the
SEC's views in applying generally accepted accounting principles to revenue
recognition in financial statements. Registrants can apply the accounting and
disclosure requirements of this SAB retrospectively, or may report a change in
accounting principle no later than the first fiscal quarter of the fiscal year

beginning after December 15, 1999. The Company does not expect the application
of this SAB to have a material impact on the Company's financial statements.

(r)  SEGMENT INFORMATION


     The Company operates under one business segment providing data storage
management and data access solutions products and services. The Company's
revenues from foreign countries represent approximately 6% of total revenues for
the years ended December 31, 1997, 1998 and 1999.


NOTE 2 -- COMMON STOCK


     The Company is incorporated in the State of Delaware and has the authority
to issue 20,000,000 shares of common stock with a par value of $.01.



     In December 1998, the Company issued a warrant to purchase 30,000 shares of
the Company's common stock at $1.84 per share to the estate of a former
employee. The warrant is exercisable for a period of five years. In accordance
with SFAS No. 123, the Company has recorded compensation expense during 1998 of
$30,000 for the estimated fair value of the warrant.

NOTE 4 -- NOTES RECEIVABLE


     Other assets at December 31, 1998 and 1999 include a $49,142 demand note
receivable from a former employee. The note bears interest at 10%.



     The Company had stock subscription notes receivable at December 31, 1998
and 1999 in the amount of approximately $977,000 from certain employees of the
Company with interest rates ranging from 5% to 8%. The notes were issued in
connection with the issuance of 745,444 shares of the Company's common stock.
Approximately 476,190 of the shares were issued in connection with a restricted
stock purchase under the Company's 1998 Stock Incentive Plan (the "Stock Plan").
Approximately $103,000 of the notes are due in January 2002, and approximately
$874,000 are due in October 2004. The Company has full recourse against the
employees to collect these notes. These notes receivable are recorded as an
offset to equity in the accompanying consolidated balance sheets. The Company
has not accrued interest on the notes.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)


NOTE 5 -- DEMAND NOTE PAYABLE -- BANK


     At December 31, 1998, the Company had a bank demand note payable of
$2,300,000. The note required only interest payments at the bank's prime rate
plus 0.5% (9% at December 31, 1998) through March 31, 1999. The loan was
collateralized by a security interest in all of the Company's assets and was
further collateralized by the pledge of certain assets of the Company's
principal stockholders. The note required the Company to comply with certain
financial covenants, including limits on debt and maintaining tangible net
worth, as defined. The Company was in violation of certain covenants at December
31, 1998 and had received waivers from the bank for such violations. Subsequent
to December 31, 1998, this agreement was replaced with a new financing
agreement.



     In July 1999, the Company entered into a revolving line of credit agreement
which replaced the bank demand note payable at December 31, 1998. The new
agreement provides for borrowings up to $5,000,000 based on eligible accounts
receivable, as defined in the agreement, and expires in July 2000. Interest only
payments are due monthly at the bank's prime rate plus 0.5% (9% at December 31,
1999). This line is collateralized by substantially all of the Company's assets,
and requires the Company to comply with certain financial covenants as defined
by the agreement. The Company was in violation of certain covenants at December
31, 1999, and has received waivers from the bank for such violations.



     As a condition to entering into the revolving line of credit agreement, the
lender required the principal stockholder of the Company to enter into an escrow
agreement as security for payments to be made by the Company under a note issued
to a former stockholder.


NOTE 6 -- LONG-TERM DEBT


     At December 31, 1998, the Company was obligated under a severance agreement
with a former employee in the amount of $250,000. This obligation was paid in
January 1999.


     On June 9, 1998, the Company purchased from a former stockholder all of his
shares for $11,500,000. The Company paid $6,000,000 in cash and issued a note to
the former stockholder with a face value of $5,500,000 and a 10% rate of
interest. The Company recorded the note at its face value which approximated the
fair value at the date of issuance. The note calls for monthly payments of
principal and interest of $60,000 through December 15, 1999, a principal payment
of $1,000,000 on January 15, 2000, and monthly payments of principal and
interest of $100,000 thereafter, until the balance is paid. The note is due in
full 60 days after an IPO of the Company's common stock. The Company recorded
this transaction as the re-purchase and retirement of treasury stock.

     On June 9, 1998, the Company borrowed $12,000,000 by issuing notes to fund
payments required under the stock re-purchase as described above, fund
distributions to other stockholders, and to provide working capital to the
Company. The notes are made up of convertible subordinated notes amounting to
$7,636,364 and senior subordinated notes amounting to $4,363,636, as described
below. The notes and the payment of the principal and interest thereon are
subordinate to and subject to prior payment of any bank indebtedness and the
indebtedness to the former stockholder.

     The convertible subordinated notes, which are held by three noteholders,
and accrued interest thereon are due December 9, 2000. The notes bear interest
at 8% to June 9, 1999, 10% from June 9, 1999 to June 9, 2000 and 12% from June
9, 2000 to maturity. Principal and interest not paid in full at maturity shall
accrue interest at 14% increasing two percentage points each June 9 thereafter,
until paid in full or converted into common stock. At any time on or before June
9, 1999, upon the occurrence of certain events as defined in the agreement,
including the sale of the Company or

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)



breach of certain covenants, and upon the request of the holders of at least 51%
of the notes, the principal amount of the notes shall be converted into common
stock of the Company. At any time after June 9, 1999, upon request of the
holders of at least 51% of the notes, the principal amount of the notes shall be
converted into common stock of the Company. Further, the principal amount of the
notes shall be automatically converted into common stock of the Company in the
event of an offer and sale by the Company of common stock to the public at a
price not less than the price per share that results from a valuation of the
Company of $100,000,000 and which results in aggregate net proceeds to the
Company of not less than $20,000,000. The notes are convertible into common
stock of the Company at $1.835 per share, subject to anti-dilution provisions.
Upon the conversion of the principal amount of the notes, the Company shall not
be required to pay any accrued but unpaid interest on the amount converted. The
notes cannot be prepaid, in whole or in part, without prior written consent of
the noteholders.


     The senior subordinated notes, which are also held by three noteholders,
and accrued interest thereon are due on December 9, 2000. Interest is paid
quarterly on these notes which bear interest at 8% to June 9, 1999, 10% from
June 9, 1999 to June 9, 2000 and 12% from June 9, 2000 to maturity. Principal
and interest not paid in full at maturity shall accrue interest at 14%
increasing two percentage points each June 9 thereafter, until paid in full.
These notes may be prepaid at any time without penalty.


     The convertible subordinated and senior subordinated notes are secured by a
pledge of shares of common stock of the Company owned by the principal
stockholder of the Company. The convertible subordinated and senior subordinated
note agreements contain restrictive covenants, which may accelerate the due date
of the notes. The Company was not in compliance with certain of these covenants
at December 31, 1998 and 1999. However, in connection with the revolving line of
credit agreement entered into by the Company in July 1999 (see Note 5), the
holders of the convertible subordinated and senior subordinated notes entered
into "standstill agreements", which prohibit the holders from commencing any
action against the Company to enforce collection of the notes until 180 calender
days after the bank accelerates the bank indebtedness. As a result, at December
31, 1998, the Company has classified the amounts as long-term obligations in the
accompanying consolidated balance sheet.


     In accordance with EITF 86-15, "Increasing Rate Debt", the Company is
recognizing the interest related to the convertible subordinated and senior
subordinated notes using the effective interest method over the period it is
estimated that the notes will be outstanding. It is reasonably possible that
this estimate could change.

NOTE 7 -- SUBORDINATED NOTES PAYABLE -- STOCKHOLDERS


     The Company is party to revolving unsecured demand loan agreements with its
principal stockholder. Interest is due monthly at a rate of 8% per annum. In
connection with the Company's issuance of convertible subordinated and senior
subordinated notes (see Note 6), the stockholder has agreed that payment of
these notes is restricted until payment or conversion of the convertible
subordinated and senior subordinated notes.


NOTE 8 -- EMPLOYEE BENEFIT PLANS

  RETIREMENT PLANS


     The Company has a 401(k) Retirement Plan (the "Plan") covering
substantially all its employees. Participants in the Plan may elect to defer up
to 15% of their compensation. The Company may make a discretionary matching
contribution; the Company elected not to make a contribution in 1997. In 1998,
the Company began to match 25% of employee contributions up to 6% of
compensation. The amount recorded as expense for the years ended December 31,
1998 and 1999 was $60,000 and $114,000, respectively.



     The Company has a 419 Benefit Plan covering senior executives,
contributions to which are discretionary. The Company made no contributions to
the plan in 1997, 1998, or 1999.


  STOCK OPTION PLAN


     During 1998, the Board of Directors adopted the Stock Plan. The Company has
reserved up to 4,529,412 shares for issuance under the Stock Plan. All of the
Company's employees, officers, directors, consultants and advisors are eligible
to be granted options under the Stock Plan. Awards granted to any employee are
limited to 500,000 shares per calendar year. The exercise price and duration of
the option are determined by the Board at the date of grant. The options
generally vest ratably over a period of 4 years, and generally expire in 10
years. During 1998 and 1999, all options were granted to employees and directors
of the Company.



     The following table summarizes option activity for the year ended December
31, 1998 and 1999:

average remaining contractual life of the outstanding options was 9.8 and 9
years, respectively, and the number of options exercisable was 10,000 and
549,092, respectively. There were 176,702 and 594,102 options available for

     The per share weighted average fair value of the options granted during
1998 and 1999 were $0.29, and $7.06, respectively. The fair value of each option
grant is estimated on the date of grant, using the Black-Scholes options-pricing
model with the following weighted average assumptions:

     The Company applies APB Opinion No. 25 and related interpretations in
accounting for its stock options. As a result, no compensation expense was
recorded for the options granted during 1998. The Company will record
compensation expense of approximately $2,886,000 relating to options to purchase
1,024,900 shares granted in 1999 equal to the difference between the fair market
value of the Company's common stock on the grant date and the exercise price of
the options. The expense will be recognized ratably over the vesting period of
the options, which is generally four years. The Company recorded a $329,000
expense associated with the options granted during 1999 which is included as
compensation expense in the accompanying consolidated statements of operations.



     SFAS No. 123 requires pro forma net income (loss) disclosures as if the
Company had accounted for its stock options granted under the fair value method
prescribed by that statement. Had the Company used the fair value methodology
for determining compensation expense, the following table presents the pro forma
net income (loss) that would have been recorded by the Company for the options
granted during 1998 and 1999:

approximated $25,000, $88,000 and $158,000 for the years ended December 31,
1997, 1998 and 1999, respectively.



     During October 1999, the principal stockholder of the Company sold 40,000
shares of the Company's common stock to an employee of the Company for $2.75 per
share. The Company has recorded compensation expense of approximately $330,000
in the accompanying 1999 statement of operations, reflecting the difference
between the purchase price and the estimated fair value of the common stock at
the time of the purchase.


NOTE 11 -- COMMITMENTS AND CONTINGENCIES

     The Company has employment contracts with certain officers, directors, and
employees. The Company also has bonus agreements with certain employees based
upon net income, as defined in the agreements.


     If the Company consummates an IPO (as defined), the Company is obligated to
pay a former employee bonus compensation of $300,000, less any amounts then due
and outstanding to the Company.



     The Company is obligated to make payments in the amount of $80,000 per year
for the years 2000 through 2003 to the estate of a former employee. The payments
are contingent upon the Company meeting certain financial targets and other
criteria as defined in the agreement.



NOTE 12 -- SUBSEQUENT EVENTS



     On January 18, 2000, the board of directors of the Company authorized the
adoption of the 2000 Stock Incentive Plan (the "2000 stock plan") and the 2000
Employee Stock Purchase Plan (the "purchase plan"). Under the 2000 stock plan,
1,000,000 shares of common stock were reserved for issuance. The 2000 stock plan
provides for the grant of incentive stock options, nonstatutory stock options,
restricted stock awards, and other stock-based awards. Subsequent to January 18,
2000, no additional stock options will be granted under the Stock Plan. The
purchase plan authorizes the issuance of up to 600,000 shares of common stock to
participating employees. Eligible employees are authorized to purchase common
stock using up to 10% of the employee's base pay at a purchase price equal to
85% of the average market price, as defined in the purchase plan.



     Additionally, on January 18, 2000 the board of directors approved an
increase in the authorized number of common stock to 65,000,000, and authorized
5,000,000 shares of preferred stock with a par value of $.01.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Registrant's Amended and Restated Certificate of Incorporation (the
"Restated Certificate") provides that, except to the extent prohibited by the
Delaware General Corporation Law (the "DGCL"), the Registrant's directors shall
not be personally liable to the Registrant or its stockholders for monetary
damages for any breach of fiduciary duty as directors of the Registrant. Under
the DGCL, the directors have a fiduciary duty to the Registrant which is not
eliminated by this provision of the Restated Certificate and, in appropriate
circumstances, equitable remedies such as injunctive or other forms of
nonmonetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for breach of the director's
duty of loyalty to the Registrant, for acts or omissions which are found by a
court of competent jurisdiction to be not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are prohibited by the DGCL. This provision
also does not affect the directors' responsibilities under any other laws, such
as the federal securities laws or state or federal environmental laws. The
Registrant has obtained liability insurance for its officers and directors.

     Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) arising under Section 174 of the DGCL including
for an unlawful payment of dividend or unlawful stock purchase or redemption, or
(iv) for any transaction from which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any

                                      II-1
<PAGE>   88

other rights to which the directors and officers may be entitled under the
corporation's by-laws, any agreement, a vote of stockholders or otherwise. The
Restated Certificate eliminates the personal liability of directors to the
fullest extent permitted by the DGCL and, together with the Registrant's Amended
and Restated By-Laws (the "Restated By-Laws") and Indemnification Agreements to
be entered into with each executive officer and director, provides that the
Registrant shall fully indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative) by
reason of the fact that such person is or was a director or officer of the
Registrant, or is or was serving at the request of the Registrant as a director
or officer of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against expenses (including attorney's fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding. Reference is
made to the Registrant's Form of Amended and Restated Certificate of
Incorporation, Form of Amended and Restated By-Laws and Form of Indemnification
Agreement filed as Exhibits 3.2, 3.4, and 10.6 hereto, respectively.


     The Underwriting Agreement provides that the Underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of the Company against certain liabilities, including liabilities under
the Securities Act of 1933, as amended (the "Securities Act"). Reference is made
to the form of Underwriting Agreement to be filed as Exhibit 1.1 hereto.


     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Restated Certificate. The Registrant is not
aware of any threatened litigation or proceeding that may result in a claim for
such indemnification.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES


     The following information regarding the issuance of the Registrant's
securities gives effect to the two-for-one stock split of the Registrant's
common stock effected on January 18, 2000. Since December 1996, the Registrant
has issued the following securities that were not registered under the
Securities Act as summarized below.


     (a) Issuances of Capital Stock, Convertible Notes and Warrants.


          1. On January 1, 1997, our predecessor Maryland corporation issued
     8.647 shares of common stock to one of its executive officers, for an
     aggregate purchase price of $102,698. The purchaser issued our predecessor
     Maryland corporation a promissory note for the aggregate purchase price.
     The promissory note earns 8% interest per year and principal and interest
     become due and payable on January 1, 2002. In connection with the
     Registrant's reincorporation into Delaware, the Registrant issued 269,254
     shares of common stock in exchange for the 8.647 shares of the common stock
     of the Registrant's predecessor corporation. This transaction was exempt
     from registration under Section 4(2) of the Securities Act.



          2. On June 8, 1998, in connection with the Registrant's
     reincorporation into Delaware, the Registrant issued an aggregate of
     26,207,606 shares of common stock to four individuals in exchange for all
     the outstanding common stock of our predecessor Maryland corporation. This
     transaction was exempt from registration under Section 4(2) of the
     Securities Act.



          3. On June 9, 1998, the Registrant issued convertible subordinated
     notes in the aggregate principal amount of $7,636,364 to one individual and
     two institutional investors. The convertible subordinated notes earn 8%
     interest per year from the date of issuance to June 9, 1999, 10% interest
     from June 9, 1999 to June 9, 2000 and 12% interest from June 9, 2000 to
     maturity on December 9, 2000. Upon the closing of this offering, the
     principal balance of the convertible subordinated notes converts
     automatically into 4,161,506 shares of the Registrant's common stock and
     the interest


                                      II-2
<PAGE>   89


     thereon is forgiven. This transaction was exempt from registration under
     Section 4(2) of the Securities Act.



          4. On December 1, 1998, the Registrant issued a warrant to purchase
     30,000 shares of common stock to one individual in exchange for an executed
     release agreement. This transaction was exempt from registration under
     Section 4(2) of the Securities Act.



          5. On December 22, 1998, the Registrant issued an aggregate of 476,190
     shares of common stock to five employees for an aggregate purchase price of
     $873,809 pursuant to restricted stock agreements under the Registrant's
     1998 Stock Incentive Plan. The employees each issued promissory notes to
     the Registrant for their respective shares. This transaction was exempt
     from registration under Rule 701 of the Securities Act.



     (b) Certain Grants and Exercises of Stock Options. The Registrant's 1998
Stock Incentive Plan was adopted by the Board of Directors and approved by the
stockholders of the Registrant in August 1998. As of December 31, 1999, no
options to purchase shares of common stock had been exercised, options to
purchase 3,459,120 shares of common stock were outstanding and 476,190 shares of
restricted stock had been granted under the 1998 Stock Incentive Plan.



     No underwriters were involved in the foregoing sales of securities. All of
the foregoing securities are deemed restricted securities for the purposes of
the Securities Act.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the Delaware General Corporation Law, the Restated
Certificate of the registrant, the Underwriting Agreement, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act, and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, the registrant will,
unless in the opinion of counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.


     The undersigned registrant hereby undertakes that:


     (1) For purpose of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4), or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.



     (2) For purpose of determining any liability under the Securities Act, each
post-effective amendment that contains a form of prospectus shall be deemed to
be a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

                                       OF

                               OTG SOFTWARE, INC.

        OTG Software, Inc., a corporation organized and existing under and by
virtue of the General Corporation Law of the State of Delaware (the

        1.  The Corporation filed its original Certificate of Incorporation with
the Secretary of the State of Delaware on May 13, 1998.

promoted by the Corporation is as follows:

        To engage in any lawful act or activity for which corporations may be
organized under the General Corporation Law of Delaware.



                                        1

<PAGE>   2

        FOURTH: The total number of shares of all classes of stock which the
Corporation shall have authority to issue is 70,000,000 shares, consisting of
(i) 65,000,000 shares of Common Stock, $.01 par value per share ("Common
Stock"), and (ii) 5,000,000 shares of Preferred Stock, $.01 par value per share
("Preferred Stock").

        The following is a statement of the designations and the powers,
privileges and rights, and the qualifications, limitations or restrictions
thereof in respect of each class of capital stock of the Corporation.

A.      COMMON STOCK.

        1.  General. The voting, dividend and liquidation rights of the holders
of the Common Stock are subject to and qualified by the rights of the holders of
the Preferred Stock of any series as may be designated by the Board of Directors
upon any issuance of the Preferred Stock of any series.

        2.  Voting. The holders of the Common Stock are entitled to one vote for
each share held at all meetings of stockholders. There shall be no cumulative
voting.

        The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of the Corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of Delaware.

        3.  Dividends. Dividends may be declared and paid on the Common Stock
from funds lawfully available therefor as and when determined by the Board of
Directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

        4.  Liquidation. Upon the dissolution or liquidation of the Corporation,
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of the Corporation available for distribution to its
stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

B.      PREFERRED STOCK.

        Preferred Stock may be issued from time to time in one or more series,
each of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Any shares of
Preferred Stock which may be redeemed, purchased or acquired by the Corporation
may be reissued except as otherwise provided by law. Different series of
Preferred Stock shall not be construed to constitute different classes of shares
for the purposes of voting by classes unless expressly provided.



                                        2

<PAGE>   3

        Authority is hereby expressly granted to the Board of Directors from
time to time to issue the Preferred Stock in one or more series, and in
connection with the creation of any such series, by resolution or resolutions
providing for the issue of the shares thereof, to determine and fix such voting
powers, full or limited, or no voting powers, and such designations, preferences
and relative participating, optional or other special rights, and
qualifications, limitations or restrictions thereof, including without
limitation thereof, dividend rights, conversion rights, redemption privileges
and liquidation preferences, as shall be stated and expressed in such
resolutions, all to the full extent now or hereafter permitted by the General
Corporation Law of Delaware. Without limiting the generality of the foregoing,
the resolutions providing for issuance of any series of Preferred Stock may
provide that such series shall be superior or rank equally or be junior to the
Preferred Stock of any other series to the extent permitted by law. Except as
otherwise provided in this Certificate of Incorporation, no vote of the holders
of the Preferred Stock or Common Stock shall be a prerequisite to the
designation or issuance of any shares of any series of the Preferred Stock
authorized by and complying with the conditions of this Certificate of
Incorporation, the right to have such vote being expressly waived by all present
and future holders of the capital stock of the Corporation.

        FIFTH.  The Corporation shall have a perpetual existence.

        SIXTH.  Whenever a compromise or arrangement is proposed between this
corporation and its creditors or any class of them and/or between this
corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of this corporation or of any creditor or stockholder thereof, or on the
application of any receiver or receivers appointed for this corporation under
the provisions of section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers appointed
for this corporation under the provisions of section 279 of Title 8 of the
Delaware Code order a meeting of the creditors or class of creditors, and/or of
the stockholders or class of stockholders of this corporation, as the case may
be, to be summoned in such manner as the said court directs. If a majority in
number representing three-fourths in value of the creditors or class of
creditors, and/or of the stockholders or class of stockholders of this
corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of this corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of this corporation, as the case may be,
and also on this corporation.

        SEVENTH. Except to the extent that the General Corporation Law of
Delaware prohibits the elimination or limitation of liability of directors for
breaches of fiduciary duty, no director of the Corporation shall be personally
liable to the Corporation or its stockholders for monetary damages for any
breach of fiduciary duty as a director, notwithstanding any provision of law
imposing such liability. No amendment to or repeal of this provision shall apply
to or have any effect on the liability or alleged liability of any director of
the Corporation for or with respect to any acts or omissions of such director
occurring prior to such amendment.



                                        3

<PAGE>   4

        EIGHTH. 1. Actions, Suits and Proceedings Other than by or in the Right
of the Corporation. The Corporation shall indemnify each person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the Corporation), by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) (all such persons being
referred to hereafter as an "Indemnitee"), or by reason of any action alleged to
have been taken or omitted in such capacity, against all expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such action, suit
or proceeding and any appeal therefrom, if he acted in good faith and in a
manner he reasonably believed to be in, or not opposed to, the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful. Notwithstanding
anything to the contrary in this Article, except as set forth in Section 7
below, the Corporation shall not indemnify an Indemnitee seeking indemnification
in connection with a proceeding (or part thereof) initiated by the Indemnitee
unless the initiation thereof was approved by the Board of Directors of the
Corporation. Notwithstanding anything to the contrary in this Article, the
Corporation shall not indemnify an Indemnitee to the extent such Indemnitee is
reimbursed from the proceeds of insurance, and in the event the Corporation
makes any indemnification payments to an Indemnitee and such Indemnitee is
subsequently reimbursed from the proceeds of insurance, such Indemnitee shall
promptly refund such indemnification payments to the Corporation to the extent
of such insurance reimbursement.

        2.  Actions or Suits by or in the Right of the Corporation. The
Corporation shall indemnify any Indemnitee who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was, or has agreed to become, a director or
officer of the Corporation, or is or was serving, or has agreed to serve, at the
request of the Corporation, as a director, officer or trustee of, or in a
similar capacity with, another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan), or by reason of any
action alleged to have been taken or omitted in such capacity, against all
expenses (including attorneys' fees) and, to the extent permitted by law,
amounts paid in settlement actually and reasonably incurred by him or on his
behalf in connection with such action, suit or proceeding and any appeal
therefrom, if he acted in good faith and in a manner he reasonably believed to
be in, or not opposed to, the best interests of the Corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the Corporation
unless and only to the extent that the Court of Chancery of Delaware shall
determine upon application that, despite the adjudication of



                                        4

<PAGE>   5

such liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses (including
attorneys' fees) which the Court of Chancery of Delaware shall deem proper.

        3.  Indemnification for Expenses of Successful Party. Notwithstanding
the other provisions of this Article, to the extent that an Indemnitee has been
successful, on the merits or otherwise, in defense of any action, suit or
proceeding referred to in Sections 1 and 2 of this Article, or in defense of any
claim, issue or matter therein, or on appeal from any such action, suit or
proceeding, he shall be indemnified against all expenses (including attorneys'
fees) actually and reasonably incurred by him or on his behalf in connection
therewith. Without limiting the foregoing, if any action, suit or proceeding is
disposed of, on the merits or otherwise (including a disposition without
prejudice), without (i) the disposition being adverse to the Indemnitee, (ii) an
adjudication that the Indemnitee was liable to the Corporation, (iii) a plea of
guilty or nolo contendere by the Indemnitee, (iv) an adjudication that the
Indemnitee did not act in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

        4.  Notification and Defense of Claim. As a condition precedent to his
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any action, suit, proceeding or investigation
involving him for which indemnity will or could be sought. With respect to any
action, suit, proceeding or investigation of which the Corporation is so
notified, the Corporation will be entitled to participate therein at its own
expense and/or to assume the defense thereof at its own expense, with legal
counsel reasonably acceptable to the Indemnitee. After notice from the
Corporation to the Indemnitee of its election so to assume such defense, the
Corporation shall not be liable to the Indemnitee for any legal or other
expenses subsequently incurred by the Indemnitee in connection with such claim,
other than as provided below in this Section 4. The Indemnitee shall have the
right to employ his own counsel in connection with such claim, but the fees and
expenses of such counsel incurred after notice from the Corporation of its
assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Article. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above.

        5.  Advance of Expenses. Subject to the provisions of Section 6 below,
in the event that the Corporation does not assume the defense pursuant to
Section 4 of this Article of any action, suit, proceeding or investigation of
which the Corporation receives notice under this



                                        5

<PAGE>   6

Article, any expenses (including attorneys' fees) incurred by an Indemnitee in
defending a civil or criminal action, suit, proceeding or investigation or any
appeal therefrom shall be paid by the Corporation in advance of the final
disposition of such matter; provided, however, that the payment of such expenses
incurred by an Indemnitee in advance of the final disposition of such matter
shall be made only upon receipt of an undertaking by or on behalf of the
Indemnitee to repay all amounts so advanced in the event that it shall
ultimately be determined that the Indemnitee is not entitled to be indemnified
by the Corporation as authorized in this Article; and further provided that no
such advancement of expenses shall be made if it is determined that (i) the
Indemnitee did not act in good faith and in a manner he reasonably believes to
be in, or not opposed to, the best interests of the Corporation, or (ii) with
respect to any criminal action or proceeding, the Indemnitee had reasonable
cause to believe his conduct was unlawful. Such undertaking shall be accepted
without reference to the financial ability of the Indemnitee to make such
repayment.

        6.  Procedure for Indemnification. In order to obtain indemnification or
advancement of expenses pursuant to Section 1, 2, 3 or 5 of this Article, the
Indemnitee shall submit to the Corporation a written request, including in such
request such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to determine whether and to what extent
the Indemnitee is entitled to indemnification or advancement of expenses. Any
such indemnification or advancement of expenses shall be made promptly, and in
any event within 60 days after receipt by the Corporation of the written request
of the Indemnitee, unless with respect to requests under Section 1, 2 or 5 the
Corporation determines within such 60-day period that the Indemnitee did not
meet the applicable standard of conduct set forth in Section 1, 2 or 5, as the
case may be. Such determination shall be made in each instance (a) by a majority
vote of the directors of the Corporation consisting of persons who are not at
that time parties to the action, suit or proceeding in question ("disinterested
directors"), whether or not a quorum, (b) by a majority vote of a committee of
disinterested directors designated by majority vote of disinterested directors,
whether or not a quorum, (c), if there are no disinterested directors, or if
disinterested directors so direct, by independent legal counsel (who may, to the
extent permitted by law, be regular legal counsel to the Corporation) in a
written opinion, or (d) by the stockholders of the Corporation.

        7.  Remedies. The right to indemnification or advances as granted by
this Article shall be enforceable by the Indemnitee in any court of competent
jurisdiction if the Corporation denies such request, in whole or in part, or if
no disposition thereof is made within the 60-day period referred to above in
Section 6. Unless otherwise required by law, the burden of proving that the
Indemnitee is not entitled to indemnification or advancement of expenses under
this Article shall be on the Corporation. Neither the failure of the Corporation
to have made a determination prior to the commencement of such action that
indemnification is proper in the circumstances because the Indemnitee has met
the applicable standard of conduct, nor an actual determination by the
Corporation pursuant to Section 6 that the Indemnitee has not met such
applicable standard of conduct, shall be a defense to the action or create a
presumption that the Indemnitee has not met the applicable standard of conduct.
The Indemnitee's expenses (including attorneys' fees) incurred in connection
with successfully establishing his right to



                                        6

<PAGE>   7

indemnification, in whole or in part, in any such proceeding shall also be
indemnified by the Corporation.

        8.  Subsequent Amendment. No amendment, termination or repeal of this
Article or of the relevant provisions of the General Corporation Law of Delaware
or any other applicable laws shall affect or diminish in any way the rights of
any Indemnitee to indemnification under the provisions hereof with respect to
any action, suit, proceeding or investigation arising out of or relating to any
actions, transactions or facts occurring prior to the final adoption of such
amendment, termination or repeal.

        9.  Other Rights. The indemnification and advancement of expenses
provided by this Article shall not be deemed exclusive of any other rights to
which an Indemnitee seeking indemnification or advancement of expenses may be
entitled under any law (common or statutory), agreement or vote of stockholders
or disinterested directors or otherwise, both as to action in his official
capacity and as to action in any other capacity while holding office for the
Corporation, and shall continue as to an Indemnitee who has ceased to be a
director or officer, and shall inure to the benefit of the estate, heirs,
executors and administrators of the Indemnitee. Nothing contained in this
Article shall be deemed to prohibit, and the Corporation is specifically
authorized to enter into, agreements with officers and directors providing
indemnification rights and procedures different from those set forth in this
Article. In addition, the Corporation may, to the extent authorized from time to
time by its Board of Directors, grant indemnification rights to other employees
or agents of the Corporation or other persons serving the Corporation and such
rights may be equivalent to, or greater or less than, those set forth in this
Article.

        10. Partial Indemnification. If an Indemnitee is entitled under any
provision of this Article to indemnification by the Corporation for some or a
portion of the expenses (including attorneys' fees), judgments, fines or amounts
paid in settlement actually and reasonably incurred by him or on his behalf in
connection with any action, suit, proceeding or investigation and any appeal
therefrom but not, however, for the total amount thereof, the Corporation shall
nevertheless indemnify the Indemnitee for the portion of such expenses
(including attorneys' fees), judgments, fines or amounts paid in settlement to
which the Indemnitee is entitled.

        11. Insurance. The Corporation may purchase and maintain insurance, at
its expense, to protect itself and any director, officer, employee or agent of
the Corporation or another corporation, partnership, joint venture, trust or
other enterprise (including any employee benefit plan) against any expense,
liability or loss incurred by him in any such capacity, or arising out of is
status as such, whether or not the Corporation would have the power to indemnify
such person against such expense, liability or loss under the General
Corporation Law of Delaware.

        12. Merger or Consolidation. If the Corporation is merged into or
consolidated with another corporation and the Corporation is not the surviving
corporation, the surviving corporation shall assume the obligations of the
Corporation under this Article with respect to any action, suit, proceeding or
investigation arising out of or relating to any actions, transactions or facts
occurring prior to the date of such merger or consolidation.



                                        7

<PAGE>   8

        13. Savings Clause. If this Article or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify each Indemnitee as to any expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement in
connection with any action, suit, proceeding or investigation, whether civil,
criminal or administrative, including an action by or in the right of the
Corporation, to the fullest extent permitted by any applicable portion of this
Article that shall not have been invalidated and to the fullest extent permitted
by applicable law.

        14. Definitions. Terms used herein and defined in Section 145(h) and
Section 145(i) of the General Corporation Law of Delaware shall have the
respective meanings assigned to such terms in such Section 145(h) and Section
145(i).

        15. Subsequent Legislation. If the General Corporation Law of Delaware
is amended after adoption of this Article to expand further the indemnification
permitted to Indemnitees, then the Corporation shall indemnify such persons to
the fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

        NINTH. Except as otherwise provided herein, the Corporation reserves the
right to amend, alter, change or repeal any provision contained in this
Certificate of Incorporation, in the manner now or hereafter prescribed by
statute and this Certificate of Incorporation, and all rights conferred upon
stockholders herein are granted subject to this reservation.

        TENTH. This Article is inserted for the management of the business and
for the conduct of the affairs of the Corporation, and shall become effective
beginning upon, and only upon, the closing of a public offering of the Company's
Common Stock registered under the Securities Act of 1933, as amended (an "IPO").

        1.  Number of Directors; Election of Directors. The number of directors
of the Corporation shall not be more than thirteen nor less than six. The exact
number of directors within the limitations specified in the preceding sentence
shall be fixed from time to time by, or in the manner provided in, the
Corporation's By-Laws. Election of directors need not be by written ballot,
except as and to the extent provided in the By-Laws of the Corporation.

        2.  Classes of Directors. The Board of Directors shall be and is divided
into three classes: Class I, Class II and Class III. No one class shall have
more than one director more than any other class. If a fraction is contained in
the quotient arrived at by dividing the designated number of directors by three,
then, if such fraction is one-third, the extra director shall be a member of
Class I, and if such fraction is two-thirds, one of the extra directors shall be
a member of Class I and one of the extra directors shall be a member of Class
II, unless otherwise provided from time to time by resolution adopted by the
Board of Directors.

        3.  Terms of Office. Each director shall serve for a term ending on the
date of the third annual meeting of stockholders following the annual meeting at
which such director was elected; provided, that each initial director in Class I
shall serve for a term ending on the date of the annual meeting in 2001; each
initial director in Class II shall serve for a term ending on the date of the
annual meeting in 2002; and each initial director in Class III shall serve for a
term



                                        8

<PAGE>   9

ending on the date of the annual meeting in 2003; and provided further, that the
term of each director shall be subject to the election and qualification of his
successor and to his earlier death, resignation or removal.

        4.  Allocation of Directors Among Classes in the Event of Increases or
Decreases in the Number of Directors. In the event of any increase or decrease
in the authorized number of directors, (i) each director then serving as such
shall nevertheless continue as a director of the class of which he or she is a
member (subject to Section 3 above) and (ii) the newly created or eliminated
directorships resulting from such increase or decrease shall be apportioned by
the Board of Directors among the three classes of directors so as to ensure that
no one class has more than one director more than any other class.

        5.  Quorum; Action at Meeting. A majority of the directors at any time
in office shall constitute a quorum for the transaction of business. In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each director so
disqualified, provided that in no case shall less than one-third of the number
of directors then in office constitute a quorum. If at any meeting of the Board
of Directors there shall be less than such a quorum, a majority of those present
may adjourn the meeting from time to time. Every act or decision done or made by
a majority of the directors present at a meeting duly held at which a quorum is
present shall be regarded as the act of the Board of Directors unless a greater
number is required by law, by the By-Laws of the Corporation or by this
Certificate of Incorporation.

        6.  Removal. Directors of the Corporation may be removed by the
stockholders only for cause by the affirmative vote of the holders of at least
sixty-six and two-thirds percent (66 2/3%) of the votes which all the
stockholders would be entitled to cast in any annual election of directors or
class of directors.

        7.  Vacancies. Any vacancy in the Board of Directors, however occurring,
including a vacancy resulting from an enlargement of the Board, shall be filled
only by a vote of a majority of the directors then in office, although less than
a quorum, or by a sole remaining director. A director elected to fill a vacancy
shall be elected to hold office until the next election of the class for which
such director shall have been chosen, subject to the election and qualification
of his successor and to his earlier death, resignation or removal.

        8.  Stockholder Nominations and Introduction of Business, Etc. Advance
notice of stockholder nominations for election of directors and other business
to be brought by stockholders before a meeting of stockholders shall be given in
the manner provided by the By-Laws of the Corporation.

        9.  Amendments to Article. Notwithstanding any other provisions of law,
this Certificate of Incorporation or the By-Laws of the Corporation, and
notwithstanding the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of at least sixty-six and two-thirds percent
(66 2/3%) of the votes which all the stockholders would be entitled to cast in
any annual election of directors or class of directors shall be required to
amend or repeal,



                                        9

<PAGE>   10

or to adopt any provision inconsistent with, this Article TENTH after it shall
have become effective.

        ELEVENTH. Effective beginning upon the closing of the Company's IPO,
stockholders of the Corporation may not take any action by written consent in
lieu of a meeting. Notwithstanding any other provisions of law, the Certificate
of Incorporation or the By-Laws of the Corporation, and notwithstanding the fact
that a lesser percentage may be specified by law, the affirmative vote of the
holders of at least sixty-six and two-thirds percent (66 2/3%) of the votes
which all the stockholders would be entitled to cast in any annual election of
directors or class of directors shall be required to amend or repeal, or to
adopt any provision inconsistent with, this Article ELEVENTH after it shall have
become effective.

        TWELFTH. Effective beginning upon the closing of the Company's IPO,
special meetings of stockholders may be called at any time only by the Chairman
of the Board of Directors, the President or the Board of Directors.
Notwithstanding any other provision of law, this Certificate of Incorporation or
the By-Laws of the Corporation, and notwithstanding the fact that a lesser
percentage may be specified by law, the affirmative vote of the holders of at
least sixty-six and two-thirds percent (66 2/3%) of the votes which all the
stockholders would be entitled to cast in any annual election of directors or
class of directors shall be required to amend or repeal, or to adopt any
provision inconsistent with, this Article TWELFTH after it shall have become
effective.

        THIRTEENTH: In furtherance and not in limitation of the powers conferred
upon it by the laws of the State of Delaware, the Board of Directors shall have
the power to adopt, amend, alter or repeal the Corporation's By-Laws. The
affirmative vote of a majority of the directors present at any regular or
special meeting of the Board of Directors at which a quorum is present shall be
required to adopt, amend, alter or repeal the Corporation's By-Laws. The
Corporation's By-Laws also may be adopted, amended, altered or repealed by the
affirmative vote of the holders of at least sixty-six and two-thirds percent
(66 2/3%) of the votes which all the stockholders would be entitled to cast in
any annual election of directors or class of directors. Notwithstanding any
other provision of law, this Certificate of Incorporation or the By-Laws of the
Corporation, and notwithstanding the fact that a lesser percentage may be
specified by law, the affirmative vote of the holders of at least sixty-six and
two-thirds percent (66 2/3%) of the votes which all the stockholders would be
entitled to cast in any annual election of directors or class of directors shall
be required to amend or repeal, or to adopt any provision inconsistent with,
this Article THIRTEENTH.

of directors and for the transaction of such other business as may properly be

where the meeting is to be held) at the time and place to be fixed by the Board
of Directors or the President and stated in the notice of the meeting. If no
annual meeting is held in accordance with the foregoing provisions, the Board of
Directors shall cause the meeting to be held as soon thereafter as convenient.
If no annual meeting is held in accordance with the foregoing provisions, a
special meeting may be held in lieu of the annual meeting, and any action taken
at that special meeting shall have the same effect as if it had been taken at
the annual meeting, and in such case all references in these By-laws to the
annual meeting of the stockholders shall be deemed to refer to such special
meeting.

        1.3  Special Meetings. Special meetings of stockholders may be called at
any time by the President or by the Board of Directors. Business transacted at
any special meeting of stockholders shall be limited to matters relating to the

corporation shall prepare and make, at least 10 days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
10 days prior to the meeting, at a place within the city where the meeting is to
be held. The list shall also be produced and kept at the time and place of the
meeting during the whole time of the meeting, and may be inspected by any
stockholder who is present.

        1.6  Quorum. Except as otherwise provided by law, the Certificate of
Incorporation or these By-laws, the holders of a majority of the shares of the

        1.7  Adjournments. Any meeting of stockholders may be adjourned to any
other time and to any other place at which a meeting of stockholders may be held
under these By-laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting. It shall not be necessary to notify any stockholder of any adjournment

share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
in the Certificate of Incorporation. Each stockholder of record entitled to vote

action in writing without a meeting, may vote or express such consent or dissent
in person or may authorize another person or persons to vote or act for him by

        1.9  Action at Meeting. When a quorum is present at any meeting, the
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of stock of
that class representing a majority of the votes cast on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws. When a quorum is present at any meeting, any
election by stockholders shall be determined by a plurality of the votes cast on
the election.

        1.10 Action without Meeting. Any action required or permitted to be
taken at any annual or special meeting of stockholders of the corporation may be
taken without a meeting, without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote on such action were present and voted. Prompt notice of the
taking of corporate action without a meeting by less than unanimous written
consent shall be given to those stockholders who have not consented in writing.

                              ARTICLE 2 - Directors

        2.1  General Powers. The business and affairs of the corporation shall
be managed by or under the direction of a Board of Directors, who may exercise
all of the powers of the corporation except as otherwise provided by law or the
Certificate of Incorporation. In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

        2.2  Number; Election and Qualification. The number of directors which
shall constitute the whole Board of Directors shall be determined by resolution
of the stockholders or the Board of Directors, but in no event shall be less
than one. The number of directors may be decreased at any time and from time to
time either by the stockholders or by a majority of the directors then in
office, but only to eliminate vacancies existing by reason of the death,
resignation, removal or expiration of the term of one or more directors. The
directors shall be elected at the annual meeting of stockholders by such
stockholders as have the right to vote on such election. Directors need not be
stockholders of the corporation.



                                       -5-

<PAGE>   6

        2.3  Enlargement of the Board. The number of directors may be increased
at any time and from time to time by the stockholders or by a majority of the
directors then in office.

        2.4  Tenure. Each director shall hold office until the next annual
meeting and until his successor is elected and qualified, or until his earlier
death, resignation or removal.

        2.5  Vacancies. Unless and until filled by the stockholders, any vacancy
in the Board of Directors, however occurring, including a vacancy resulting from
an enlargement of the Board, may be filled by vote of a majority of the
directors then in office, although less than a quorum, or by a sole remaining
director. A director elected to fill a vacancy shall be elected for the
unexpired term of his predecessor in office, and a director chosen to fill a
position resulting from an increase in the number of directors shall hold office
until the next annual meeting of stockholders and until his successor is elected
and qualified, or until his earlier death, resignation or removal.

        2.6  Resignation. Any director may resign by delivering his written
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

        2.7  Regular Meetings. Regular meetings of the Board of Directors may be
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall
be given notice of the determination. A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

        2.8  Special Meetings. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

        2.9  Notice of Special Meetings. Notice of any special meeting of
directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting. Notice shall be duly given to each
director (i) by giving notice to such director in person or by telephone at
least 48 hours in advance of the meeting, (ii) by sending a telegram or telex,
or delivering written notice by hand, to his last known business or home address
at least 48



                                       -6-

<PAGE>   7

hours in advance of the meeting, or (iii) by mailing written notice to his last
known business or home address at least 72 hours in advance of the meeting. A
notice or waiver of notice of a meeting of the Board of Directors need not
specify the purposes of the meeting.

        2.10 Meetings by Telephone Conference Calls. Directors or any members of
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

        2.11 Quorum. A majority of the total number of the whole Board of
Directors shall constitute a quorum at all meetings of the Board of Directors.
In the event one or more of the directors shall be disqualified to vote at any
meeting, then the required quorum shall be reduced by one for each such director
so disqualified; provided, however, that in no case shall less than one-third
(1/3) of the number so fixed constitute a quorum. In the absence of a quorum at
any such meeting, a majority of the directors present may adjourn the meeting
from time to time without further notice other than announcement at the meeting,
until a quorum shall be present.

        2.12 Action at Meeting. At any meeting of the Board of Directors at
which a quorum is present, the vote of a majority of those present shall be
sufficient to take any action, unless a different vote is specified by law, the
Certificate of Incorporation or these By-Laws.

        2.13 Action by Consent. Any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee of the Board of
Directors may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent to the action in writing, and the written
consents are filed with the minutes of proceedings of the Board or committee.

        2.14 Removal. Except as otherwise provided by the General Corporation
Law of Delaware, any one or more or all of the directors may be removed, with or
without cause, by the holders of a majority of the shares then entitled to vote
at an election of directors, except that the directors elected by the holders of
a particular class or series of stock may be removed without cause only by vote
of the holders of a majority of the outstanding shares of such class or series.

        2.15 Committees. The Board of Directors may designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The Board may designate one or more directors as alternate members
of any committee, who may replace any



                                       -7-

<PAGE>   8

absent or disqualified member at any meeting of the committee. In the absence or
disqualification of a member of a committee, the member or members of the
committee present at any meeting and not disqualified from voting, whether or
not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such absent or

indemnity as the Board of Directors may require for the protection of the
corporation or any transfer agent or registrar.

        4.5  Record Date. The Board of Directors may fix in advance a date as a
record date for the determination of the stockholders entitled to notice of or
to vote at any meeting of stockholders or to express consent (or dissent) to
corporate action in writing without a meeting, or entitled to receive payment of
any dividend or other distribution or allotment of any rights in respect of any
change, conversion or exchange of stock, or for the purpose of any other lawful

to any other action to which such record date relates.

If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day before the day on which notice is given, or, if
notice is waived, at the close of business on the day before the day on which
the meeting is held. The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the Board of Directors is necessary, shall be the day on which the
first written consent is properly delivered to the corporation. The record date
for determining stockholders for any other purpose shall be at the close of
business on the day on which the Board of Directors adopts the resolution
relating to such purpose.

A determination of stockholders of record entitled to notice of or to vote at a

of such notice either in writing signed by the person entitled to such notice or
such person's duly authorized attorney, or by telegraph, cable or any other

the appearance of such person or persons at such meeting in person or by proxy,

Assistant Secretary, or a temporary Secretary, as to any action taken by the
stockholders, directors, a committee or any officer or representative of the

the corporation and any other corporation, partnership, association, or other
organization in which one or more of the directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or a committee of the
Board of Directors which authorizes the contract or transaction or solely
because his or their votes are counted for such purpose, if:

        (1)  The material facts as to his relationship or interest and as to the
contract or transaction are disclosed or are known to the Board of Directors or
the committee, and the Board or committee in good faith authorizes the contract
or transaction by the affirmative votes of a majority of the disinterested

        (2)  The material facts as to his relationship or interest and as to the
contract or transaction are disclosed or are known to the stockholders entitled
to vote thereon, and the contract or transaction is specifically approved in
good faith by vote of the stockholders; or

        (3)  The contract or transaction is fair as to the corporation as of the
time it is authorized, approved or ratified, by the Board of Directors, a
committee of the Board of Directors, or the stockholders.

Common or interested directors may be counted in determining the presence of a
quorum at a meeting of the Board of Directors or of a committee which authorizes
the contract or transaction.

refer to the masculine, feminine or neuter, singular or plural, as the identity
of the person or persons may require.

the directors present at any regular or special meeting of the Board of
Directors at which a quorum is present.

repealed or new by-laws may be adopted by the affirmative vote of the holders of
a majority of the shares of the capital stock of the corporation issued and
outstanding and entitled to vote at any regular meeting of stockholders, or at
any special meeting of stockholders, provided notice of such alteration,
amendment, repeal or adoption of new by-laws shall have been stated in the
notice of such special meeting.

President and stated in the notice of the meeting. If no annual meeting is held
in accordance with the foregoing provisions, the Board of Directors shall cause
the meeting to be held as soon thereafter as is convenient. If no annual meeting
is held in accordance with the foregoing provisions, a special meeting may be
held in lieu of the annual meeting, and any action taken at that special meeting
shall have the same effect as if it had been taken at the annual meeting, and in
such case all references in these By-Laws to the annual meeting of the
stockholders shall be deemed to refer to such special meeting.

        3.   Special Meetings. Special meetings of stockholders may be called at
any time only by the Chairman of the Board, the President or the Board of
Directors. Business transacted at any special meeting of stockholders shall be
limited to matters relating to the purpose or purposes stated in the notice of

share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
by law, the Certificate of Incorporation or these By-Laws. Each stockholder of
record entitled to vote at a meeting of stockholders may vote in person or may
authorize another person or persons to vote or act for him by proxy executed in
writing (or in such other manner as permitted under Delaware law) by the
stockholder or his authorized agent and delivered to the Secretary of the
corporation. No such proxy shall be voted or acted upon after three years from
the date of its execution, unless the proxy expressly provides for a longer
period.

        9.   Action at Meeting. When a quorum is present at any meeting, the
holders of shares of stock representing a majority of the votes cast on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of shares of that
class of stock representing a majority of the votes cast on a matter) shall
decide any matter to be voted upon by the stockholders at such meeting, except
when a different vote is required by express provision of law, the Certificate
of Incorporation or these By-Laws. Any election by stockholders shall be
determined by a plurality of the votes cast by the stockholders entitled to vote
at the election.

        10.  Nomination of Directors. Only persons who are nominated in
accordance with the following procedures shall be eligible for election as
directors (except for directors elected to fill vacancies, as provided in

corporation at a meeting of stockholders may be made (i) by or at the direction
of the Board of Directors or (ii) by any stockholder of the corporation entitled
to vote for the



                                       -2-

<PAGE>   3

election of directors at such meeting who complies with the notice procedures
set forth in this Section 10.

        To be timely, a stockholder's notice must be received by the Secretary
at the principal executive offices of the corporation as follows: (a) in the
case of an election of directors at an annual meeting of stockholders, not less
than 60 days nor more than 90 days prior to the first anniversary of the
preceding year's annual meeting; provided, however, that (i) in the event that
the date of the annual meeting is advanced by more than 20 days, or delayed by
more than 60 days, from such anniversary date, to be timely, a stockholder's
notice must be so received not earlier than the 90th day prior to such annual
meeting and not later than the close of business on the later of (A) the 60th
day prior to such annual meeting and (B) the 10th day following the day on which
notice of the date of such annual meeting was mailed or public disclosure of the
date of such annual meeting was made, whichever first occurs, or (ii) with
respect to the annual meeting of stockholders of the corporation to be held in
the year 2000, to be timely, a stockholder's notice must be so received not
earlier than the 90th day prior to such annual meeting and not later than the
close of business on the 10th day following the day on which notice of the date
of such annual meeting was mailed or public disclosure of the date of such
annual meeting was made, whichever first occurs; or (b) in the case of an
election of directors at a special meeting of stockholders, not earlier than the
ninetieth day prior to such special meeting and not later than the close of
business on the later of (A) the sixtieth day prior to such special meeting and
(B) the 10th day following the day on which notice of the date of such special
meeting was mailed or public disclosure of the date of such special meeting was
made, whichever first occurs.

        The stockholder's notice to the Secretary shall set forth (a) as to each
proposed nominee (i) the name, age, business address and, if known, residence
address of each such nominee, (ii) the principal occupation or employment of
each such nominee, (iii) the number of shares of stock of the corporation which
are beneficially owned by each such nominee, and (iv) any other information
concerning the nominee that must be disclosed as to nominees in proxy
solicitations pursuant to Regulation 14A under the Securities Exchange Act of
1934, as amended; (b) as to the stockholder giving the notice (i) the name and
address, as they appear on the corporation's books, of such stockholder and (ii)
the class and number of shares of the corporation which are beneficially owned
by such stockholder; and (c) as to the beneficial owner, if any, on whose behalf
the nomination is being made (i) the name and address of such beneficial owner
and (ii) the class and number of shares of the corporation which are
beneficially owned by such person. In addition, to be effective, the
stockholder's notice must be accompanied by the written consent of the proposed
nominee to serve as a director if elected. The corporation may require any
proposed nominee to furnish such other information as may reasonably be required
by the corporation to determine the eligibility of such proposed nominee to
serve as a director of the corporation.

        The chairman of the meeting may, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

thereto) given by or at the direction of the Board of Directors, (b) otherwise
brought before the meeting by or at the direction of the Board of Directors, or

business to be properly brought before an annual meeting by a stockholder, (i)
if such business relates to the election of directors of the corporation, the
procedures in Section 10 of Article I must be complied with and (ii) if such
business relates to any other matter, the stockholder must have given timely

        12.  Action without Meeting. Stockholders may not take any action by
written consent in lieu of a meeting.

        13.  Conduct of Meetings. The Board of Directors of the corporation may
adopt by resolution such rules, regulations and procedures for the conduct of
any meeting of stockholders of the corporation as it shall deem appropriate.
Except to the extent inconsistent with such rules, regulations and procedures as
adopted by the Board of Directors, the officer of the corporation presiding at
any meeting of stockholders shall have the right and authority to prescribe such
rules, regulations and procedures and to do all such acts as, in the judgment of
such officer, are appropriate for the proper conduct of the meeting. Such rules,

        The officer of the corporation presiding at any meeting of stockholders

accepted.

                             ARTICLE II - DIRECTORS

        1.   General Powers. The business and affairs of the corporation shall
be managed by or under the direction of a Board of Directors, who may exercise
all of the powers of the corporation except as otherwise provided by law, the
Certificate of Incorporation or these By-Laws. In the event of a vacancy in the
Board of Directors, the remaining directors, except as otherwise provided by
law, may exercise the powers of the full Board until the vacancy is filled.

        2.   Number; Election and Qualification. The number of directors which
shall constitute the whole Board of Directors shall be determined by resolution
of the Board of Directors, but in no event shall be more than thirteen nor less
than three. The number of



                                       -5-

<PAGE>   6

directors may be decreased at any time and from time to time by a majority of
the directors then in office, but only to eliminate vacancies existing by reason
of the death, resignation, removal or expiration of the term of one or more
directors. The directors shall be elected at the annual meeting of stockholders
by such stockholders as have the right to vote on such election. Directors need
not be stockholders of the corporation.

        3.   Classes of Directors. The Board of Directors shall be and is
divided into three classes: Class I, Class II and Class III. No one class shall
have more than one director more than any other class. If a fraction is
contained in the quotient arrived at by dividing the designated number of
directors by three, then, if such fraction is one-third, the extra director
shall be a member of Class I, and if such fraction is two-thirds, one of the
extra directors shall be a member of Class I and one of the extra directors
shall be a member of Class II, unless otherwise provided from time to time by
resolution adopted by the Board of Directors.

        4. Terms of Office. Each director shall serve for a term ending on the
date of the third annual meeting of stockholders following the annual meeting at
which such director was elected; provided, that each initial director in Class I
shall serve for a term ending on the date of the annual meeting of stockholders
in 2001; each initial director in Class II shall serve for a term ending on the
date of the annual meeting of stockholders in 2002, and each initial director in
Class III shall serve for a term ending on the date of the annual meeting of
stockholders in 2003; and provided further, that the term of each director shall
be subject to the election and qualification of his successor and to his earlier
death, resignation or removal.

        5.   Allocation of Directors Among Classes in the Event of Increases or
Decreases in the Number of Directors. In the event of any increase or decrease
in the authorized number of directors, (i) each director then serving as such
shall nevertheless continue as a director of the class of which he or she is a
member (subject to Section 4 above) and (ii) the newly created or eliminated
directorships resulting from such increase or decrease shall be apportioned by
the Board of Directors among the three classes of directors so as to ensure that
no one class has more than one director more than any other class.

        6.   Quorum; Action at Meeting. A majority of the directors at any time
in office shall constitute a quorum for the transaction of business. In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each director so
disqualified, provided that in no case shall less than one-third (a) of the
number of directors then in office constitute a quorum. If at any meeting of the
Board of Directors there shall be less than such a quorum, a majority of those
present may adjourn the meeting from time to time. Every act or decision done or
made by a majority of the directors present at a meeting duly held at which a
quorum is present shall be regarded as the act of the Board of Directors unless
a greater number is required by law, by the Certificate of Incorporation or
these By-Laws.

        7.   Removal. Directors of the corporation may be removed by the
stockholders only for cause by the affirmative vote of the holders of at least
sixty-six and two-thirds percent (66 2/3%) of the votes which all the
stockholders would be entitled to cast in any annual election of directors or
class of directors.



                                       -6-

<PAGE>   7

        8.   Vacancies. Any vacancy in the Board of Directors, however
occurring, including a vacancy resulting from an enlargement of the Board, shall
be filled only by vote of a majority of the directors then in office, although
less than a quorum, or by a sole remaining director. A director elected to fill
a vacancy shall be elected to hold office until the next election of the class
for which such director shall have been chosen, subject to the election and
qualification of his successor and to his earlier death, resignation or removal.

        9.   Resignation. Any director may resign by delivering his written
resignation to the corporation at its principal office or to the Chairman of the
Board or Secretary. Such resignation shall be effective upon receipt unless it
is specified to be effective at some other time or upon the happening of some
other event.

        10.  Regular Meetings. Regular meetings of the Board of Directors may be
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
provided that any director who is absent when such a determination is made shall
be given notice of the determination. A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

        11.  Special Meetings. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, two or more directors, or by
one director in the event that there is only a single director in office.

        12.  Notice of Special Meetings. Notice of any special meeting of
directors shall be given to each director by the Secretary or by the officer or
one of the directors calling the meeting. Notice shall be duly given to each
director (i) by giving notice to such director in person or by telephone at
least 24 hours in advance of the meeting, (ii) by sending a telegram, telecopy,
telex or electronic mail, or delivering written notice by hand, to his last
known business, home or electronic mail address at least 24 hours in advance of
the meeting, or (iii) by mailing written notice to his last known business or
home address at least 72 hours in advance of the meeting. A notice or waiver of
notice of a meeting of the Board of Directors need not specify the purposes of
the meeting.

        13.  Meetings by Telephone Conference Calls. Directors or any members of
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

        14.  Action by Consent. Any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee of the Board of
Directors may be taken without a meeting, if all members of the Board or
committee, as the case may be, consent to the action in



                                       -7-

<PAGE>   8

writing, and the written consents are filed with the minutes of proceedings of
the Board or committee.

        15.  Committees. The Board of Directors may designate one or more
committees, each committee to consist of one or more of the directors of the
corporation. The Board may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of the committee. In the absence or disqualification of a member of a
committee, the member or members of the committee present at any meeting and not
disqualified from voting, whether or not he or they constitute a quorum, may
unanimously appoint another member of the Board of Directors to act at the
meeting in the place of any such absent or disqualified member. Any such
committee, to the extent provided in the resolution of the Board of Directors
and subject to the provisions of the General Corporation Law of the State of
Delaware, shall have and may exercise all the powers and authority of the Board
of Directors in the management of the business and affairs of the corporation
and may authorize the seal of the corporation to be affixed to all papers which
may require it. Each such committee shall keep minutes and make such reports as
the Board of Directors may from time to time request. Except as the Board of
Directors may otherwise determine, any committee may make rules for the conduct
of its business, but unless otherwise provided by the directors or in such
rules, its business shall be conducted as nearly as possible in the same manner
as is provided in these By-Laws for the Board of Directors.

        16.  Compensation of Directors. Directors may be paid such compensation
for their services and such reimbursement for expenses of attendance at meetings
as the Board of Directors may from time to time determine. No such payment shall
preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for
such service.

                             ARTICLE III - OFFICERS

        1.   Enumeration. The officers of the corporation shall consist of a
President, a Secretary, a Treasurer and such other officers with such other
titles as the Board of Directors shall determine, including a Chairman of the

offices may be held by the same person.

        4.   Tenure. Except as otherwise provided by law, by the Certificate of
Incorporation or by these By-Laws, each officer shall hold office until his
successor is elected and qualified, unless a different term is specified in the
vote choosing or appointing him, or until his earlier death, resignation or
removal.

        5.   Resignation and Removal. Any officer may resign by delivering his
or her written resignation to the corporation at its principal office or to the
Chairman of the Board, President or Secretary. Such resignation shall be
effective upon receipt unless it is specified to be effective at some other time
or upon the happening of some other event.

        Any officer may be removed at any time, with or without cause, by vote
of a majority of the entire number of directors then in office.

        Except as the Board of Directors may otherwise determine, no officer who
resigns or is removed shall have any right to any compensation as an officer for
any period following his resignation or removal, or any right to damages on
account of such removal, whether his compensation be by the month or by the year
or otherwise, unless such compensation is expressly provided in a duly
authorized written agreement with the corporation.

        6.   Vacancies. The Board of Directors may fill any vacancy occurring in
any office for any reason and may, in its discretion, leave unfilled for such
period as it may determine any offices other than those of President, Treasurer
and Secretary. Each such successor shall hold office for the unexpired term of
his predecessor and until his successor is elected and qualified, or until his
earlier death, resignation or removal.

        7.   Chairman of the Board and Vice Chairman of the Board. The Board of
Directors may appoint a Chairman of the Board and may designate the Chairman of

general charge and supervision of the business of the corporation.

corporation or its transfer agent of the certificate representing such shares
properly endorsed or accompanied by a written assignment or power of attorney
properly executed, and with such proof of authority or the authenticity of
signature as the corporation or its transfer agent may reasonably require.
Except as may be otherwise required by law, by the Certificate of Incorporation
or by these By-Laws, the corporation shall be entitled to treat the record
holder of stock as shown on its books as the owner of such stock for all
purposes, including the payment of dividends and the right to vote with respect

which such record date relates.

        If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the

notice is waived, at the close of business on the day before the day on which
the meeting is held. The record date for determining stockholders for any other
purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating to such purpose.

        A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;

        3.   Waiver of Notice. Whenever any notice whatsoever is required to be
given by law, by the Certificate of Incorporation or by these By-Laws, a waiver
of such notice either in writing signed by the person entitled to such notice or
such person's duly authorized attorney, or by telecopy or any other available
method, whether before, at or after the time stated in such waiver, or the
appearance of such person or persons at such meeting in person or by proxy,
shall be deemed equivalent to such notice.

        4.   Voting of Securities. Except as the directors may otherwise
designate, the Chairman of the Board or Treasurer may waive notice of, and act
as, or appoint any person or persons to act as, proxy or attorney-in-fact for
this corporation (with or without power of substitution) at any meeting of
stockholders or shareholders of any other corporation or organization, the
securities of which may be held by this corporation.

        5.   Evidence of Authority. A certificate by the Secretary, or an
Assistant Secretary, or a temporary Secretary, as to any action taken by the
stockholders, directors, a committee or any officer or representative of the
corporation shall as to all persons who rely on the certificate in good faith be
conclusive evidence of such action.

the Certificate of Incorporation shall be deemed to refer to the Amended and
Restated Certificate of Incorporation of the corporation, as amended and in

between the corporation and one or more of the directors or officers, or between
the corporation and any other corporation, partnership, association, or other
organization in which one or more of the directors or officers are directors or
officers, or have a financial interest, shall be void or voidable solely for
this reason, or solely because the director or officer is present at or
participates in the meeting of the Board of Directors or a committee of the
Board of Directors which authorizes the contract or transaction or solely
because his or their votes are counted for such purpose, if:

             a. The material facts as to his relationship or interest and as to
        the contract or transaction are disclosed or are known to the Board of
        Directors or the committee, and the Board or committee in good faith
        authorizes the contract or transaction by the affirmative votes of a
        majority of the disinterested directors, even though the disinterested
        directors be less than a quorum;

             b. The material facts as to his relationship or interest and as to
        the contract or transaction are disclosed or are known to the
        stockholders entitled to vote thereon, and the contract or transaction
        is specifically approved in good faith by vote of the stockholders; or

             c. The contract or transaction is fair as to the corporation as of
        the time it is authorized, approved or ratified, by the Board of
        Directors, a committee of the Board of Directors, or the stockholders.

        Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the Board of Directors or of a committee
which authorizes the contract or transaction.

                         OPTICAL TECHNOLOGY GROUP, INC.

                            1998 STOCK INCENTIVE PLAN

1.   Purpose

The purpose of this 1998 Stock Incentive Plan (the "Plan") of Optical Technology
Group, Inc., a Delaware corporation (the "Company"), is to advance the interests
of the Company's stockholders by enhancing the Company's ability to attract,
retain and motivate persons who make (or are expected to make) important
contributions to the Company by providing such persons with equity ownership
opportunities and performance-based incentives and thereby better aligning the
interests of such persons with those of the Company's stockholders. Except where
the context otherwise requires, the term "Company" shall include any present or
future subsidiary corporations of Optical Technology Group, Inc. as defined in
Section 424(f) of the Internal Revenue Code of 1986, as amended, and any
regulations promulgated thereunder (the "Code").

2.   Eligibility

All of the Company's employees, officers, directors, consultants and advisors
(and any individuals who have accepted an offer for employment) are eligible to
be granted options, restricted stock awards, or other stock-based awards (each,
an "Award") under the Plan. Each person who has been granted an Award under the
Plan shall be deemed a "Participant".

3.   Administration, Delegation

     (a)  Administration by Board of Directors. The Plan will be administered by
the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

     (b)  Delegation to Executive Officers. To the extent permitted by
applicable law, the Board may delegate to one or more executive officers of the
Company the power to make Awards and exercise such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of shares subject to Awards and the maximum number of shares for any one
Participant to be made by such executive officers.

     (c)  Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). If and when the common
stock, $.01 par value

per share, of the Company (the "Common Stock") is registered under the
Securities Exchange Act of 1934 (the "Exchange Act"), the Board shall appoint
one such Committee of not less than two members, each member of which shall be
an "outside director" within the meaning of Section 162(m) of the Code and a
"non-employee director" as defined in Rule 16b-3 promulgated under the Exchange
Act." All references in the Plan to the "Board" shall mean the Board or a
Committee of the Board or the executive officer referred to in Section 3(b) to
the extent that the Board's powers or authority under the Plan have been
delegated to such Committee or executive officer.

4.   Stock Available for Awards

     (a)  Number of Shares. Subject to adjustment under Section 8, Awards may be
made under the Plan for up to 2,264,706 shares of Common Stock. If any Award
expires or is terminated, surrendered or canceled without having been fully
exercised or is forfeited in whole or in part or results in any Common Stock not
being issued, the unused Common Stock covered by such Award shall again be
available for the grant of Awards under the Plan, subject, however, in the case
of Incentive Stock Options (as hereinafter defined), to any limitation required
under the Code. Shares issued under the Plan may consist in whole or in part of
authorized but unissued shares or treasury shares.

     (b)  Per-Participant Limit. Subject to adjustment under Section 8, for
Awards granted after the Common Stock is registered under the Exchange Act, the
maximum number of shares of Common Stock with respect to which an Award may be
granted to any Participant under the Plan shall be 250,000 per calendar year.
The per-Participant limit described in this Section 4(b) shall be construed and
applied consistently with Section 162(m) of the Code.

5.   Stock Options.

     (a)  General. The Board may grant options to purchase Common Stock (each,
an "Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option."

     (b)  Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c)  Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement.

     (d)  Duration of Options. Each Option shall be exercisable at such times
and subject to such terms and conditions as the Board may specify in the
applicable option agreement.

                                      -2-

     (e)  Exercise of Option. Options may be exercised by delivery to the
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

     (f)  Payment Upon Exercise. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

          (1)  in cash or by check, payable to the order of the Company;

          (2)  except as the Board may, in its sole discretion, otherwise
provide in an option agreement, (i) delivery of an irrevocable and unconditional
undertaking by a creditworthy broker to deliver promptly to the Company
sufficient funds to pay the exercise price, or (ii) delivery by the Participant
to the Company of a copy of irrevocable and unconditional instructions to a
creditworthy broker to deliver promptly to the Company cash or a check
sufficient to pay the exercise price;

          (3)  while the Common Stock is registered under the Exchange Act,
delivery of shares of Common Stock owned by the Participant valued at their fair
market value as determined by (or in a manner approved by) the Board in good
faith ("Fair Market Value"), which Common Stock was owned by the Participant at
least six months prior to such delivery;

          (4)  to the extent permitted by the Board, in its sole discretion (i)
by delivery of a promissory note of the Participant to the Company on terms
determined by the Board, or (ii) by payment of such other lawful consideration
as the Board may determine; or

          (5)  any combination of the above permitted forms of payment.

6.   Restricted Stock

     (a)  Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, "Restricted Stock Award").

     (b)  Terms and Conditions. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board, deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the applicable restriction periods, the
Company (or such designee) shall deliver the certificates no longer subject to
such restrictions to the Participant or if the Participant has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive amounts due or exercise rights of the Participant in the event of the
Participant's death (the "Designated Beneficiary"). In the absence of an
effective designation by a Participant, Designated Beneficiary shall mean the
Participant's estate.

7.   Other Stock-Based Awards

The Board shall have the right to grant other Awards based upon the Common Stock
having such terms and conditions as the Board may determine, including the grant
of shares based upon certain conditions, the grant of securities convertible
into Common Stock and the grant of stock appreciation rights.

8.   Adjustments for Changes in Common Stock and Certain Other Events

     (a)  Changes in Capitalization. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant limit set forth in Section 4(b), (iii) the number and
class of securities and exercise price per share subject to each outstanding
Option, (iv) the repurchase price per share subject to each outstanding
Restricted Stock Award, and (v) the terms of each other outstanding Award shall
be appropriately adjusted by the Company (or substituted Awards may be made, if
applicable) to the extent the Board shall determine, in good faith, that such an
adjustment (or substitution) is necessary and appropriate. If this Section 8(a)
applies and Section 8(c) also applies to any event, Section 8(c) shall be
applicable to such event, and this Section 8(a) shall not be applicable.

     (b)  Liquidation or Dissolution. In the event of a proposed liquidation or
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

     (c)  Acquisition and Change in Control Events

          (1)  Definitions

               (a)  An "Acquisition Event" shall mean:

                    (i)  any merger or consolidation of the Company with or into
                         another entity as a result of which the Common Stock is
                         converted into or exchanged for the right to receive
                         cash, securities or other property; or

                         share exchange transaction.

                         common stock or voting securities of the Company,
                         unless the Person exercising, converting or exchanging
                         such security acquired such security directly from the
                         Company or an underwriter or agent of the Company), (B)

                         "Business Combination"), unless, immediately following
                         such Business Combination, each of the following two
                         conditions is satisfied: (x) all or substantially all

                         Business Combination (which shall include, without
                         limitation, a corporation which as a result of such
                         transaction owns the Company or substantially all of
                         the Company's assets either directly or through one or

                         corporation is referred to herein as the "Acquiring

                         their ownership of the Outstanding Company Common Stock
                         and Outstanding Company Voting Securities,

                         Combination and (y) no Person (excluding the Acquiring
                         Corporation or any employee benefit plan (or related
                         trust) maintained or sponsored by the Company or by the
                         Acquiring Corporation or the Exempt Person)

                         of the then-outstanding shares of common stock of the

                         to the Business Combination).

          (2)  Effect on Options

               (a)  Acquisition Event. Upon the occurrence of an Acquisition
                    Event (regardless of whether such event also constitutes a
                    Change in Control Event), or the execution by the Company of
                    any agreement with respect to an Acquisition Event
                    (regardless of whether such



                                      -6-
<PAGE>   7

                    event will result in a Change in Control Event), the Board
                    shall provide that all outstanding Options shall be assumed,
                    or equivalent options shall be substituted, by the acquiring
                    or succeeding corporation (or an affiliate thereof);
                    provided that if such Acquisition Event also constitutes a
                    Change in Control Event, except to the extent specifically
                    provided to the contrary in the instrument evidencing any
                    Option or any other agreement between a Participant and the
                    Company, such assumed or substituted options shall be
                    immediately exercisable in full upon the occurrence of such
                    Acquisition Event for all Options held by Participants that
                    have had a relationship with the Company as an employee,
                    officer, director, consultant or advisor for one year prior
                    to such Change in Control Event. For purposes hereof, an
                    Option shall be considered to be assumed if, following
                    consummation of the Acquisition Event, the Option confers
                    the right to purchase, for each share of Common Stock
                    subject to the Option immediately prior to the consummation
                    of the Acquisition Event, the consideration (whether cash,
                    securities or other property) received as a result of the
                    Acquisition Event by holders of Common Stock for each share
                    of Common Stock held immediately prior to the consummation
                    of the Acquisition Event (and if holders were offered a
                    choice of consideration, the type of consideration chosen by
                    the holders of a majority of the outstanding shares of
                    Common Stock); provided, however, that if the consideration
                    received as a result of the Acquisition Event is not solely
                    common stock of the acquiring or succeeding corporation (or
                    an affiliate thereof), the Company may, with the consent of
                    the acquiring or succeeding corporation, provide for the
                    consideration to be received upon the exercise of Options to
                    consist solely of common stock of the acquiring or
                    succeeding corporation (or an affiliate thereof) equivalent
                    in fair market value to the per share consideration received
                    by holders of outstanding shares of Common Stock as a result
                    of the Acquisition Event.

                         Notwithstanding the foregoing, if the acquiring or
                    succeeding corporation (or an affiliate thereof) does not
                    agree to assume, or substitute for, such Options, then the
                    Board shall, upon written notice to the Participants,
                    provide that all then unexercised Options will become
                    exercisable in full as of a specified time prior to the
                    Acquisition Event and will terminate immediately prior to
                    the consummation of such Acquisition Event, except to the
                    extent exercised by the Participants before the consummation
                    of such Acquisition Event; provided, however, in the event
                    of an Acquisition Event under the terms of which holders of
                    Common Stock will receive upon consummation thereof a cash
                    payment for each share of Common Stock surrendered pursuant
                    to such Acquisition Event (the "Acquisition Price"), then
                    the Board may



                                      -7-
<PAGE>   8

                    instead provide that all outstanding Options shall terminate
                    upon consummation of such Acquisition Event and that each
                    Participant shall receive, in exchange therefor, a cash
                    payment equal to the amount (if any) by which (A) the
                    Acquisition Price multiplied by the number of shares of
                    Common Stock subject to such outstanding Options (whether or
                    not then exercisable), exceeds (B) the aggregate exercise
                    price of such Options.

               (b)  Change in Control Event that is not an Acquisition Event.
                    Upon the occurrence of a Change in Control Event that does
                    not also constitute an Acquisition Event, except to the
                    extent specifically provided to the contrary in the
                    instrument evidencing any Option or any other agreement
                    between a Participant and the Company, all Options
                    then-outstanding shall automatically become immediately
                    exercisable in full for all Options held by Participants
                    that have had a relationship with the Company as an
                    employee, officer, director, consultant or advisor for one
                    year prior to such Change in Control Event.

          (3)  Effect on Restricted Stock Awards

               (a)  Acquisition Event that is not a Change in Control Event.
                    Upon the occurrence of an Acquisition Event that is not a
                    Change in Control Event, the repurchase and other rights of
                    the Company under each outstanding Restricted Stock Award
                    shall inure to the benefit of the Company's successor and
                    shall apply to the cash, securities or other property which
                    the Common Stock was converted into or exchanged for
                    pursuant to such Acquisition Event in the same manner and to
                    the same extent as they applied to the Common Stock subject
                    to such Restricted Stock Award.

               (b)  Change in Control Event. Upon the occurrence of a Change in
                    Control Event (regardless of whether such event also
                    constitutes an Acquisition Event), except to the extent
                    specifically provided to the contrary in the instrument
                    evidencing any Restricted Stock Award or any other agreement
                    between a Participant and the Company, all restrictions and
                    conditions on all Restricted Stock Awards then-outstanding
                    shall automatically be deemed terminated or satisfied for
                    all Options held by Participants that have had a
                    relationship with the Company as an employee, officer,
                    director, consultant or advisor for one year prior to such
                    Change in Control Event.

          (4)  Effect on Other Awards

               (a)  Acquisition Event that is not a Change in Control Event. The
                    Board shall specify the effect of an Acquisition Event that
                    is not a



                                      -8-
<PAGE>   9

                    Change in Control Event on any other Award granted under the
                    Plan at the time of the grant of such Award.

               (b)  Change in Control Event. Upon the occurrence of a Change in
                    Control Event (regardless of whether such event also
                    constitutes an Acquisition Event), except to the extent
                    specifically provided to the contrary in the instrument
                    evidencing any other Award or any other agreement between a
                    Participant and the Company, all other Awards shall become
                    exercisable, realizable or vested in full, or shall be free
                    of all conditions or restrictions, as applicable to each
                    such Award for all Options held by Participants that have
                    had a relationship with the Company as an employee, officer,
                    director, consultant or advisor for one year prior to such
                    Change in Control Event.

9.   General Provisions Applicable to Awards

     (a)  Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b)  Documentation. Each Award shall be evidenced by a written instrument
in such form as the Board shall determine. Each Award may contain terms and
conditions in addition to those set forth in the Plan.

     (c)  Board Discretion. Except as otherwise provided by the Plan, each Award
may be made alone or in addition or in relation to any other Award. The terms of
each Award need not be identical, and the Board need not treat Participants
uniformly.

     (d)  Termination of Status. The Board shall determine the effect on an
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e)  Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, Participants may satisfy such tax obligations in whole or
in part by delivery of shares of Common Stock, including shares retained from
the Award creating the tax obligation, valued at their Fair Market Value. The
Company may, to the extent permitted by law and to the extent not otherwise
paid, deduct any such tax obligations from any payment of any kind otherwise due
to a Participant.



                                      -9-
<PAGE>   10

     (f)  Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g)  Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h)  Acceleration. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock
Awards shall be free of restrictions in full or in part or that any other Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

10.  Miscellaneous

     (a)  No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b)  No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

     (c)  Effective Date and Term of Plan. The Plan shall become effective on
the date on which it is adopted by the Board. No Awards shall be granted under
the Plan after the completion of ten years from the earlier of (i) the date on
which the Plan was adopted by the



                                      -10-
<PAGE>   11

Board or (ii) the date the Plan was approved by the Company's stockholders, but
Awards previously granted may extend beyond that date.

     (d)  Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time.

     (e)  Governing Law. The provisions of the Plan and all Awards made
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.

                               OTG SOFTWARE, INC.

                            2000 STOCK INCENTIVE PLAN

1.   Purpose

     The purpose of this 2000 Stock Incentive Plan (the "Plan") of OTG Software,
Inc., a Delaware corporation (the "Company"), is to advance the interests of the
Company's stockholders by enhancing the Company's ability to attract, retain and
motivate persons who make (or are expected to make) important contributions to
the Company by providing such persons with equity ownership opportunities and
performance-based incentives and thereby better aligning the interests of such
persons with those of the Company's stockholders. Except where the context
otherwise requires, the term "Company" shall include any of the Company's
present or future subsidiary corporations as defined in Section 424(f) of the
Internal Revenue Code of 1986, as amended, and any regulations promulgated
thereunder (the "Code").

2.   Eligibility

     All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan. Each person who has been granted an
Award under the Plan shall be deemed a "Participant".

3.   Administration, Delegation

     (a)  Administration by Board of Directors. The Plan will be administered by
the Board of Directors of the Company (the "Board"). The Board shall have
authority to grant Awards and to adopt, amend and repeal such administrative
rules, guidelines and practices relating to the Plan as it shall deem advisable.
The Board may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem expedient to carry the Plan into effect and it shall be the sole and final
judge of such expediency. All decisions by the Board shall be made in the
Board's sole discretion and shall be final and binding on all persons having or
claiming any interest in the Plan or in any Award. No director or person acting
pursuant to the authority delegated by the Board shall be liable for any action
or determination relating to or under the Plan made in good faith.

     (b)  Delegation to Executive Officers. To the extent permitted by
applicable law, the Board may delegate to one or more executive officers of the
Company the power to make Awards and exercise such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of shares subject to Awards and the maximum number of shares for any one
Participant to be made by such executive officers.


<PAGE>   2

     (c)  Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). All references in the
Plan to the "Board" shall mean the Board or a Committee of the Board or the
executive officer referred to in Section 3(b) to the extent that the Board's
powers or authority under the Plan have been delegated to such Committee or
executive officer.

4.   Stock Available for Awards

     (a)  Number of Shares. Subject to adjustment under Section 8, Awards may be
made under the Plan for up to 1,000,000 shares of common stock, par value $0.01
per share, of the Company (the "Common Stock").

     (b)  The number of shares of Common Stock available for issuance under the
Plan shall automatically increase on the first trading day of each calendar
year, beginning with the 2001 calendar year and continuing through the term of
this Plan, by an amount equal to three percent (3%) of the shares of Common
Stock outstanding on the last trading day of the preceding calendar year;
provided, however, that in no event shall any such annual increase exceed
1,000,000 shares.

     (c)  If any Award expires or is terminated, surrendered or canceled without
having been fully exercised or is forfeited in whole or in part or results in
any Common Stock not being issued, the unused Common Stock covered by such Award
shall again be available for the grant of Awards under the Plan, subject,
however, in the case of Incentive Stock Options (as hereinafter defined), to any
limitation required under the Code. Shares issued under the Plan may consist in
whole or in part of authorized but unissued shares or treasury shares.

5.   Stock Options

     (a)  General. The Board may grant options to purchase Common Stock (each,
an "Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

     (b)  Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c)  Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement;
provided, however, that the exercise price of all Incentive Stock Options shall
not be less than 100% of the fair market value



                                      2
<PAGE>   3

of the Common Stock, as determined by the Board, at the time the Incentive Stock
Option is granted.

     (d)  Duration of Options. Each Option shall be exercisable at such times
and subject to such terms and conditions as the Board may specify in the
applicable option agreement; provided, however, that no Option will be granted
for a term in excess of 10 years.

     (e)  Exercise of Option. Options may be exercised by delivery to the
Company of a written notice of exercise signed by the proper person or by any
other form of notice (including electronic notice) approved by the Board
together with payment in full as specified in Section 5(f) for the number of
shares for which the Option is exercised.

     (f)  Payment Upon Exercise. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

          (1)  in cash or by check, payable to the order of the Company;

          (2)  except as the Board may, in its sole discretion, otherwise
provide in an option agreement, by (i) delivery of an irrevocable and
unconditional undertaking by a creditworthy broker to deliver promptly to the
Company sufficient funds to pay the exercise price or (ii) delivery by the
Participant to the Company of a copy of irrevocable and unconditional
instructions to a creditworthy broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price;

          (3)  when the Common Stock is registered under the Exchange Act, by
delivery of shares of Common Stock owned by the Participant valued at their fair
market value as determined by (or in a manner approved by) the Board in good
faith ("Fair Market Value"), provided (i) such method of payment is then
permitted under applicable law and (ii) such Common Stock was owned by the
Participant at least six months prior to such delivery;

          (4)  payment of such other lawful consideration as the Board may
determine; or

          (5)  by any combination of the above permitted forms of payment.

6.   Restricted Stock

     (a)  Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b)  Terms and Conditions. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the



                                      3
<PAGE>   4

issue price, if any. Any stock certificates issued in respect of a Restricted
Stock Award shall be registered in the name of the Participant and, unless
otherwise determined by the Board, deposited by the Participant, together with a
stock power endorsed in blank, with the Company (or its designee). At the
expiration of the applicable restriction periods, the Company (or such designee)
shall deliver the certificates no longer subject to such restrictions to the
Participant or if the Participant has died, to the beneficiary designated, in a
manner determined by the Board, by a Participant to receive amounts due or
exercise rights of the Participant in the event of the Participant's death (the
"Designated Beneficiary"). In the absence of an effective designation by a
Participant, Designated Beneficiary shall mean the Participant's estate.

7.   Other Stock-Based Awards

     The Board shall have the right to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the
grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.

8.   Adjustments for Changes in Common Stock and Certain Other Events

     (a)  Changes in Capitalization. In the event of any stock split, reverse
stock split, stock dividend, recapitalization, combination of shares,
reclassification of shares, spin-off or other similar change in capitalization
or event, or any distribution to holders of Common Stock, other than a normal
cash dividend and other than the stock split declared by the Board on January
18, 2000, (i) the number and class of securities available under this Plan, (ii)
the number and class of securities and exercise price per share subject to each
outstanding Option, (iii) the repurchase price per share subject to each
outstanding Restricted Stock Award, and (iv) the terms of each other outstanding
Award shall be appropriately adjusted by the Company (or substituted Awards may
be made, if applicable) to the extent the Board shall determine, in good faith,
that such an adjustment (or substitution) is necessary and appropriate. If this
Section 8(a) applies and Section 8(c) also applies to any event, Section 8(c)
shall be applicable to such event, and this Section 8(a) shall not be
applicable.

     (b)  Liquidation or Dissolution. In the event of a proposed liquidation or
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

     (c)  Acquisition and Change in Control Events

          (1)  Definitions

               (a)  An "Acquisition Event" shall mean:

<PAGE>   5

                    (i)  any merger or consolidation of the Company with or into
                         another entity as a result of which the Common Stock is
                         converted into or exchanged for the right to receive
                         cash, securities or other property; or

                    (ii) any exchange of shares of the Company for cash,
                         securities or other property pursuant to a statutory
                         share exchange transaction.

               (b)  A "Change in Control Event" shall mean:

                    (i)  the acquisition by an individual, entity or group
                         (within the meaning of Section 13(d)(3) or 14(d)(2) of
                         the Securities Exchange Act of 1934, as amended (the
                         "Exchange Act")) (a "Person") of beneficial ownership
                         of any capital stock of the Company if, after such
                         acquisition, such Person beneficially owns (within the
                         meaning of Rule 13d-3 promulgated under the Exchange
                         Act) more than 50% of either (x) the then-outstanding
                         shares of common stock of the Company (the "Outstanding
                         Company Common Stock") or (y) the combined voting power
                         of the then-outstanding securities of the Company
                         entitled to vote generally in the election of directors
                         (the "Outstanding Company Voting Securities");
                         provided, however, that for purposes of this subsection
                         (i), the following acquisitions shall not constitute a
                         Change in Control Event: (A) any acquisition directly
                         from the Company (excluding an acquisition pursuant to
                         the exercise, conversion or exchange of any security
                         exercisable for, convertible into or exchangeable for
                         common stock or voting securities of the Company,
                         unless the Person exercising, converting or exchanging
                         such security acquired such security directly from the
                         Company or an underwriter or agent of the Company), (B)
                         any acquisition by any employee benefit plan (or
                         related trust) sponsored or maintained by the Company
                         or any corporation controlled by the Company, (C) any
                         acquisition by any corporation pursuant to a Business
                         Combination (as defined below) which complies with
                         clauses (x) and (y) of subsection (iii) of this
                         definition, or (D) any acquisition by Richard Kay (the
                         "Exempt Person") of any shares of Common Stock; or

                    (ii) such time as the Continuing Directors (as defined
                         below) do not constitute a majority of the Board (or,
                         if applicable, the Board of Directors of a successor

                              means at any date a member of the Board (x) who
                              was a member of the Board on the date of the
                              initial adoption of this Plan by the Board or (y)
                              who was nominated or elected subsequent to such
                              date by at least a majority of the directors who
                              were Continuing Directors at the time of such
                              nomination or election or whose election to the
                              Board was recommended or endorsed by at least a
                              majority of the directors who were Continuing
                              Directors at the time of such nomination or
                              election; provided, however, that there shall be
                              excluded from this clause (y) any individual whose
                              initial assumption of office occurred as a result
                              of an actual or threatened election contest with
                              respect to the election or removal of directors or
                              other actual or threatened solicitation of proxies
                              or consents, by or on behalf of a person other
                              than the Board; or

                   (iii) the consummation of a merger, consolidation,
                         reorganization, recapitalization or statutory share
                         exchange involving the Company or a sale or other
                         disposition of all or substantially all of the assets
                         of the Company (a "Business Combination"), unless,
                         immediately following such Business Combination, each
                         of the following two conditions is satisfied: (x) all
                         or substantially all of the individuals and entities
                         who were the beneficial owners of the Outstanding
                         Company Common Stock and Outstanding Company Voting
                         Securities immediately prior to such Business
                         Combination beneficially own, directly or indirectly,
                         more than 50% of the then-outstanding shares of common
                         stock and the combined voting power of the
                         then-outstanding securities entitled to vote generally
                         in the election of directors, respectively, of the
                         resulting or acquiring corporation in such Business
                         Combination (which shall include, without limitation, a
                         corporation which as a result of such transaction owns
                         the Company or substantially all of the Company's
                         assets either directly or through one or more
                         subsidiaries) (such resulting or acquiring corporation
                         is referred to herein as the "Acquiring Corporation")
                         in substantially the same proportions as their
                         ownership of the Outstanding Company Common Stock and
                         Outstanding Company Voting Securities, respectively,
                         immediately prior to such Business Combination and (y)
                         no Person (excluding the Acquiring Corporation or any
                         employee benefit plan (or related trust) maintained or

                         Corporation) beneficially owns, directly or indirectly,
                         20% or more of the then-outstanding shares of common
                         stock of the Acquiring Corporation, or of the combined
                         voting power of the then-outstanding securities of such
                         corporation

                         entitled to vote generally in the election of directors
                         (except to the extent that such ownership existed prior
                         to the Business Combination).

          (2)  Effect on Options

               (a)  Acquisition Event. Upon the occurrence of an Acquisition
                    Event (regardless of whether such event also constitutes a
                    Change in Control Event), or the execution by the Company of
                    any agreement with respect to an Acquisition Event
                    (regardless of whether such event will result in a Change in
                    Control Event), the Board shall provide that all outstanding
                    Options shall be assumed, or equivalent options shall be
                    substituted, by the acquiring or succeeding corporation (or
                    an affiliate thereof); provided that if such Acquisition
                    Event also constitutes a Change in Control Event, except to
                    the extent specifically provided to the contrary in the
                    instrument evidencing any Option or any other agreement
                    between a Participant and the Company (A) one-half of the
                    number of shares subject to the Option which were not
                    already vested shall be exercisable upon the occurrence of
                    such Acquisition Event and, the remaining one-half of such
                    number of shares shall continue to become vested in
                    accordance with the original vesting schedule set forth in
                    such option, with one-half of the number of shares that
                    would otherwise have first become vested becoming so vested
                    on each subsequent vesting date in accordance with the
                    original schedule. For purposes hereof, an Option shall be
                    considered to be assumed if, following consummation of the
                    Acquisition Event, the Option confers the right to purchase,
                    for each share of Common Stock subject to the Option
                    immediately prior to the consummation of the Acquisition
                    Event, the consideration (whether cash, securities or other
                    property) received as a result of the Acquisition Event by
                    holders of Common Stock for each share of Common Stock held
                    immediately prior to the consummation of the Acquisition
                    Event (and if holders were offered a choice of
                    consideration, the type of consideration chosen by the
                    holders of a majority of the outstanding shares of Common
                    Stock); provided, however, that if the consideration
                    received as a result of the Acquisition Event is not solely
                    common stock of the acquiring or succeeding corporation (or
                    an affiliate thereof), the Company may, with the consent of
                    the acquiring or succeeding corporation, provide for the
                    consideration to be received upon the exercise of Options to
                    consist solely of common stock of the acquiring or
                    succeeding corporation (or an affiliate thereof) equivalent
                    in fair market value to the per share consideration received
                    by holders of



                                      7
<PAGE>   8

                    outstanding shares of Common Stock as a result of the
                    Acquisition Event.

                         Notwithstanding the foregoing, if the acquiring or
                    succeeding corporation (or an affiliate thereof) does not
                    agree to assume, or substitute for, such Options, then the
                    Board shall, upon written notice to the Participants,
                    provide that all then unexercised Options will become
                    exercisable in full as of a specified time prior to the
                    Acquisition Event and will terminate immediately prior to
                    the consummation of such Acquisition Event, except to the
                    extent exercised by the Participants before the consummation
                    of such Acquisition Event; provided, however, that in the
                    event of an Acquisition Event under the terms of which
                    holders of Common Stock will receive upon consummation
                    thereof a cash payment for each share of Common Stock
                    surrendered pursuant to such Acquisition Event (the
                    "Acquisition Price"), then the Board may instead provide
                    that all outstanding Options shall terminate upon
                    consummation of such Acquisition Event and that each
                    Participant shall receive, in exchange therefor, a cash
                    payment equal to the amount (if any) by which (A) the
                    Acquisition Price multiplied by the number of shares of
                    Common Stock subject to such outstanding Options (whether or
                    not then exercisable), exceeds (B) the aggregate exercise
                    price of such Options.

               (b)  Change in Control Event that is not an Acquisition Event.
                    Upon the occurrence of a Change in Control Event that does
                    not also constitute an Acquisition Event, except to the
                    extent specifically provided to the contrary in the
                    instrument evidencing any Option or any other agreement
                    between a Participant and the Company, the vesting schedule
                    of such Option shall be accelerated in part so that one-half
                    of the number of shares that would otherwise have first
                    become vested on any date after the date of the Change in
                    Control Event shall immediately become exercisable. The
                    remaining one-half of such number of shares shall continue
                    to become vested in accordance with the original vesting
                    schedule set forth in such Option, with one-half of the
                    number of shares that would otherwise have first become
                    vested becoming so vested on each subsequent vesting date in
                    accordance with the original schedule.

          (3)  Effect on Restricted Stock Awards

               (a)  Acquisition Event that is not a Change in Control Event.
                    Upon the occurrence of an Acquisition Event that is not a
                    Change in Control Event, the repurchase and other rights of
                    the Company under each



                                      8
<PAGE>   9

                    outstanding Restricted Stock Award shall inure to the
                    benefit of the Company's successor and shall apply to the
                    cash, securities or other property which the Common Stock
                    was converted into or exchanged for pursuant to such
                    Acquisition Event in the same manner and to the same extent
                    as they applied to the Common Stock subject to such
                    Restricted Stock Award.

               (b)  Change in Control Event. Upon the occurrence of a Change in
                    Control Event (regardless of whether such event also
                    constitutes an Acquisition Event), except to the extent
                    specifically provided to the contrary in the instrument
                    evidencing any Restricted Stock Award or any other agreement
                    between a Participant and the Company, the vesting schedule
                    of all Restricted Stock Awards shall be accelerated in part
                    so that one-half of the number of shares that would
                    otherwise have first become free from conditions or
                    restrictions on any date after the date of the Change in
                    Control Event shall immediately become free from conditions
                    or restrictions. Subject to the following sentence, the
                    remaining one-half of such number of shares shall continue
                    to become free from conditions or restrictions in accordance
                    with the original schedule set forth in such Restricted
                    Stock Award, with one-half of the number of shares that
                    would otherwise have first become free from conditions or
                    restrictions becoming free from conditions or restrictions
                    on each subsequent vesting date in accordance with the
                    original schedule.

          (4)  Effect on Other Awards

               (a)  Acquisition Event that is not a Change in Control Event. The
                    Board shall specify the effect of an Acquisition Event that
                    is not a Change in Control Event on any other Award granted
                    under the Plan at the time of the grant of such Award.

               (b)  Change in Control Event. Upon the occurrence of a Change in
                    Control Event (regardless of whether such event also
                    constitutes an Acquisition Event), except to the extent
                    specifically provided to the contrary in the instrument
                    evidencing any Award or any other agreement between a
                    Participant and the Company, the vesting schedule of all
                    other Awards shall be accelerated in part so that one-half
                    of the number of shares that would otherwise have first
                    become exercisable, realizable, vested or free from
                    conditions or restrictions on any date after the date of the
                    Change in Control Event shall immediately become
                    exercisable, realizable, vested or free from conditions or
                    restrictions. Subject to the following sentence, the
                    remaining one-half of such number of shares shall



                                      9
<PAGE>   10

                    continue to become exercisable, realizable, vested or free
                    from conditions or restrictions in accordance with the
                    original schedule set forth in such Award, with one-half of
                    the number of shares that would otherwise have first become
                    exercisable, realizable, vested or free from conditions or
                    restrictions becoming so exercisable, realizable, vested or
                    free from conditions or restrictions on each subsequent
                    vesting date in accordance with the original schedule.

          (5)  Limitations. Notwithstanding the foregoing provisions of this
Section 8(c), if the Change in Control Event is intended to be accounted for as
a "pooling of interests" for financial accounting purposes, and if the
acceleration to be effected by the foregoing provisions of this Section 8(c)
would preclude accounting for the Change in Control Event as a "pooling of
interests" for financial accounting purposes, then no such acceleration shall
occur upon the Change in Control Event.

9.   General Provisions Applicable to Awards

     (a)  Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b)  Documentation. Each Award shall be evidenced by a written instrument
in such form as the Board shall determine. Each Award may contain terms and
conditions in addition to those set forth in the Plan.

     (c)  Board Discretion. Except as otherwise provided by the Plan, each Award
may be made alone or in addition or in relation to any other Award. The terms of
each Award need not be identical, and the Board need not treat Participants
uniformly.

     (d)  Termination of Status. The Board shall determine the effect on an
Award of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e)  Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may, to the extent then permitted under applicable law, satisfy
such tax obligations in whole or in part by delivery of shares of Common Stock,
including



                                      10
<PAGE>   11

shares retained from the Award creating the tax obligation, valued at
their Fair Market Value. The Company may, to the extent permitted by law, deduct
any such tax obligations from any payment of any kind otherwise due to a
Participant.

     (f)  Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g)  Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h)  Acceleration. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock
Awards shall be free of restrictions in full or in part or that any other Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

10.  Miscellaneous

     (a)  No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b)  No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather than as of the record date for such
dividend), then an optionee who exercises an Option between the record date and
the distribution date for such stock dividend shall be entitled to receive, on
the distribution date, the stock dividend with respect to the shares of Common
Stock acquired



                                      11
<PAGE>   12

upon such Option exercise, notwithstanding the fact that such
shares were not outstanding as of the close of business on the record date for
such stock dividend.

     (c)  Effective Date and Term of Plan. The Plan shall become effective on
the date on which it is adopted by the Board. No Awards shall be granted under
the Plan after the completion of ten years from the earlier of (i) the date on
which the Plan was adopted by the Board or (ii) the date the Plan was approved
by the Company's stockholders, but Awards previously granted may extend beyond
that date.

     (d)  Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time.

     (e)  Governing Law. The provisions of the Plan and all Awards made
hereunder shall be governed by and interpreted in accordance with the laws of
the State of Delaware, without regard to any applicable conflicts of law.

                                        Adopted by the Board of Directors of the
                                        Company on January 18, 2000.

                                        Approved by the stockholders of the
                                        Company on January 18, 2000.

                               OTG SOFTWARE, INC.

                        2000 EMPLOYEE STOCK PURCHASE PLAN

     The purpose of this Plan is to provide eligible employees of OTG Software,
Inc. (the "Company") and certain of its subsidiaries with opportunities to
purchase shares of the Company's common stock, par value $0.01 per share (the
"Common Stock"). Six hundred thousand (600,000) shares of Common Stock in the
aggregate have been approved for this purpose. This Plan is intended to qualify
as an "employee stock purchase plan" as defined in Section 423 of the Internal
Revenue Code of 1986, as amended (the "Code"), and the regulations promulgated
thereunder, and shall be interpreted consistent therewith.

     1.   Administration. The Plan will be administered by the Company's Board
of Directors (the "Board") or by a Committee appointed by the Board (the
"Committee"). The Board or the Committee has authority to make rules and
regulations for the administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.

     2.   Eligibility. All employees of the Company, including Directors who are
employees, and all employees of any subsidiary of the Company (as defined in
Section 424(f) of the Code) designated by the Board or the Committee from time
to time (a "Designated Subsidiary"), are eligible to participate in any one or
more of the offerings of Options (as defined in Section 9) to purchase Common
Stock under the Plan provided that:

          (a) they are customarily employed by the Company or a Designated
     Subsidiary for more than 20 hours a week and for more than six months in a
     calendar year; and

          (b) they have been employed by the Company or a Designated Subsidiary
     for at least six months prior to enrolling in the Plan; and

          (c) they are employees of the Company or a Designated Subsidiary on
     the first day of the applicable Plan Period (as defined below).

     No employee may be granted an option hereunder if such employee,
immediately after the option is granted, owns 5% or more of the total combined
voting power or value of the stock of the Company or any subsidiary. For
purposes of the preceding sentence, the attribution rules of Section 424(d) of
the Code shall apply in determining the stock ownership of an employee, and all
stock which the employee has a contractual right to purchase shall be treated as
stock owned by the employee.

     3.   Offerings. The Company will make one or more offerings ("Offerings")
to employees to purchase stock under this Plan. Offerings will begin each
January 1 and December



                                        1

<PAGE>   2

1, or the first business day thereafter (the "Offering Commencement Dates").
Each Offering Commencement Date will begin a six-month period (a "Plan Period")
during which payroll deductions will be made and held for the purchase of Common
Stock at the end of the Plan Period. The Board or the Committee may, at its
discretion, choose a different Plan Period of twelve (12) months or less for
subsequent Offerings. Notwithstanding anything to the contrary, the first Plan
Period shall begin on the first date that the Company has filed with the United
States Securities and Exchange Commission an effective Registration Statement on
Form S-8 for purposes of registering under the Securities Act of 1933, as
amended, all shares of Common Stock issuable under this Plan, and shall end on
the June 30 or December 31 first thereafter occurring.

     4.   Participation. An employee eligible on the Offering Commencement Date
of any Offering may participate in such Offering by completing and forwarding a
payroll deduction authorization form to the employee's appropriate payroll
office at least 15 days prior to the applicable Offering Commencement Date. The
form will authorize a regular payroll deduction from the Compensation received
by the employee during the Plan Period. Unless an employee files a new form or
withdraws from the Plan, his deductions and purchases will continue at the same
rate for future Offerings under the Plan as long as the Plan remains in effect.
The term "Compensation" means the amount of money reportable on the employee's
Federal Income Tax Withholding Statement, excluding overtime, shift premium,
incentive or bonus awards, allowances and reimbursements for expenses such as
relocation allowances for travel expenses, income or gains on the exercise of
Company stock options or stock appreciation rights, and similar items, whether
or not shown on the employee's Federal Income Tax Withholding Statement, but
including, in the case of salespersons, sales commissions to the extent
determined by the Board or the Committee.

     5.   Deductions. The Company will maintain payroll deduction accounts for
all participating employees. With respect to any Offering made under this Plan,
an employee may authorize a payroll deduction in any dollar amount up to a
maximum of 10% of the Compensation he or she receives during the Plan Period or
such shorter period during which deductions from payroll are made. Payroll
deductions may be at any percentage (up to 10%) of Compensation, with any change
in Compensation during the Plan Period to result in an automatic corresponding
change in the dollar amount withheld. The minimum payroll deduction is such
percentage of Compensation as may be established from time to time by the Board
or the Committee.

     No employee may be granted an Option (as defined in Section 9) which
permits his rights to purchase Common Stock under this Plan and any other
employee stock purchase plan (as defined in Section 423(b) of the Code) of the
Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the
fair market value of such Common Stock (determined at the Offering Commencement
Date of the Plan Period) for each calendar year in which the Option is
outstanding at any time.

     6.   Deduction Changes. An employee may decrease or discontinue his payroll
deduction once during any Plan Period, by filing a new payroll deduction
authorization form.



                                        2

<PAGE>   3

However, an employee may not increase his payroll deduction during a Plan
Period. If an employee elects to discontinue his payroll deductions during a
Plan Period, but does not elect to withdraw his funds pursuant to Section 8
hereof, funds deducted prior to his election to discontinue will be applied to
the purchase of Common Stock on the Exercise Date (as defined below).

     7.   Interest. Interest will not be paid on any employee accounts, except
to the extent that the Board or the Committee, in its sole discretion, elects to
credit employee accounts with interest at such per annum rate as it may from
time to time determine.

     8.   Withdrawal of Funds. An employee may at any time prior to the close of
business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering. Partial withdrawals are not
permitted. The employee may not begin participation again during the remainder
of the Plan Period. The employee may participate in any subsequent Offering in
accordance with terms and conditions established by the Board or the Committee.

     9.   Purchase of Shares. On the Offering Commencement Date of each Plan
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, the largest number of whole shares of Common Stock of the Company
as does not exceed the number of shares determined by multiplying $2,083 by the
number of full months in the Offering Period and dividing the result by the
closing price (as defined below) on the Offering Commencement Date of such Plan
Period.

     The purchase price for each share purchased will be 85% of the closing
price of the Common Stock on (i) the first business day of such Plan Period or
(ii) the Exercise Date, whichever closing price is less. Such closing price
shall be (a) the closing price on any national securities exchange on which the
Common Stock is listed, (b) the closing price of the Common Stock on the Nasdaq
National Market or (c) the average of the closing bid and asked prices in the
over-the-counter-market, whichever is applicable, as published in The Wall
Street Journal. If no sales of Common Stock were made on such a day, the price
of the Common Stock for purposes of clauses (a) and (b) above shall be the
reported price for the next preceding day on which sales were made.
Notwithstanding anything to the contrary contained herein, if the first business
day of the first plan period is the day immediately after the pricing of the
Company's initial public offering, then the purchase price for shares purchased
during that initial period will be 85% of the lower of (i) the price at which
the Common Stock is sold to the public in that offering and (ii) the closing
price of the Common Stock on the Exercise Date.

     Each employee who continues to be a participant in the Plan on the Exercise
Date shall be deemed to have exercised his Option at the Option Price on such
date and shall be deemed to have purchased from the Company the number of full
shares of Common Stock reserved for the purpose of the Plan that his accumulated
payroll deductions on such date will pay for, but not in excess of the maximum
number determined in the manner set forth above.



                                        3

<PAGE>   4

     Any balance remaining in an employee's payroll deduction account at the end
of a Plan Period will be automatically refunded to the employee, except that any
balance which is less than the purchase price of one share of Common Stock will
be carried forward into the employee's payroll deduction account for the
following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded.

     10.  Issuance of Certificates. Certificates representing shares of Common
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the Company's sole discretion) in the name
of a brokerage firm, bank or other nominee holder designated by the employee.
The Company may, in its sole discretion and in compliance with applicable laws,
authorize the use of book entry registration of shares in lieu of issuing stock
certificates.

     11.  Rights on Retirement, Death or Termination of Employment. In the event
of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any pay
due and owing to an employee and the balance in the employee's account shall be
paid to the employee or, in the event of the employee's death, (a) to a
beneficiary previously designated in a revocable notice signed by the employee
(with any spousal consent required under state law) or (b) in the absence of
such a designated beneficiary, to the executor or administrator of the
employee's estate or (c) if no such executor or administrator has been appointed
to the knowledge of the Company, to such other person(s) as the Company may, in
its discretion, designate. If, prior to the last business day of the Plan
Period, the Designated Subsidiary by which an employee is employed shall cease
to be a subsidiary of the Company, or if the employee is transferred to a
subsidiary of the Company that is not a Designated Subsidiary, the employee
shall be deemed to have terminated employment for the purposes of this Plan.

     12.  Optionees Not Stockholders. Neither the granting of an Option to an
employee nor the deductions from his pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him.

     13.  Rights Not Transferable. Rights under this Plan are not transferable
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

     14.  Application of Funds. All funds received or held by the Company under
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.

     15.  Adjustment in Case of Changes Affecting Common Stock. In the event of
a subdivision of outstanding shares of Common Stock, or the payment of a
dividend in Common Stock, other than the two-for-one stock split declared by the
Board on January 18, 2000, the number of shares approved for this Plan, and the
share limitation set forth in Section 9, shall be



                                        4

<PAGE>   5

increased proportionately, and such other adjustment shall be made as may be
deemed equitable by the Board or the Committee. In the event of any other change
affecting the Common Stock, such adjustment shall be made as may be deemed
equitable by the Board or the Committee to give proper effect to such event.

     16.  Merger. If the Company shall at any time merge or consolidate with
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 80%
by voting power of the capital stock of the surviving corporation ("Continuity
of Control"), the holder of each Option then outstanding will thereafter be
entitled to receive at the next Exercise Date upon the exercise of such Option
for each share as to which such Option shall be exercised the securities or
property which a holder of one share of the Common Stock was entitled to upon
and at the time of such merger or consolidation, and the Board or the Committee
shall take such steps in connection with such merger or consolidation as the
Board or the Committee shall deem necessary to assure that the provisions of
Section 15 shall thereafter be applicable, as nearly as reasonably may be, in
relation to the said securities or property as to which such holder of such
Option might thereafter be entitled to receive thereunder.

     In the event of a merger or consolidation of the Company with or into
another corporation which does not involve Continuity of Control, or of a sale
of all or substantially all of the assets of the Company while unexercised
Options remain outstanding under the Plan, (a) subject to the provisions of
clauses (b) and (c), after the effective date of such transaction, each holder
of an outstanding Option shall be entitled, upon exercise of such Option, to
receive in lieu of shares of Common Stock, shares of such stock or other
securities as the holders of shares of Common Stock received pursuant to the
terms of such transaction; or (b) all outstanding Options may be cancelled by
the Board or the Committee as of a date prior to the effective date of any such
transaction and all payroll deductions shall be paid out to the participating
employees; or (c) all outstanding Options may be cancelled by the Board or the
Committee as of the effective date of any such transaction, provided that notice
of such cancellation shall be given to each holder of an Option, and each holder
of an Option shall have the right to exercise such Option in full based on
payroll deductions then credited to his account as of a date determined by the
Board or the Committee, which date shall not be less than ten (10) days
preceding the effective date of such transaction.

     17.  Amendment of the Plan. The Board may at any time, and from time to
time, amend this Plan in any respect, except that (a) if the approval of any
such amendment by the shareholders of the Company is required by Section 423 of
the Code, such amendment shall not be effected without such approval, and (b) in
no event may any amendment be made which would cause the Plan to fail to comply
with Section 423 of the Code.

     18.  Insufficient Shares. In the event that the total number of shares of
Common Stock specified in elections to be purchased under any Offering plus the
number of shares purchased under previous Offerings under this Plan exceeds the
maximum number of shares issuable under this Plan, the Board or the Committee
will allot the shares then available on a pro rata basis.



                                        5

<PAGE>   6

     19.  Termination of the Plan. This Plan may be terminated at any time by
the Board. Upon termination of this Plan all amounts in the accounts of
participating employees shall be promptly refunded.

     20.  Governmental Regulations. The Company's obligation to sell and deliver
Common Stock under this Plan is subject to listing on a national stock exchange
or quotation on the Nasdaq National Market (to the extent the Common Stock is
then so listed or quoted) and the approval of all governmental authorities
required in connection with the authorization, issuance or sale of such stock.

     21.  Governing Law. The Plan shall be governed by Delaware law except to
the extent that such law is preempted by federal law.

     22.  Issuance of Shares. Shares may be issued upon exercise of an Option
from authorized but unissued Common Stock, from shares held in the treasury of
the Company, or from any other proper source.

     23.  Notification upon Sale of Shares. Each employee agrees, by entering
the Plan, to promptly give the Company notice of any disposition of shares
purchased under the Plan where such disposition occurs within two years after
the date of grant of the Option pursuant to which such shares were purchased.

     24.  Effective Date and Approval of Shareholders. The Plan shall take
effect on January 18, 2000 subject to approval by the shareholders of the
Company as required by Section 423 of the Code, which approval must occur within
twelve months of the adoption of the Plan by the Board.


                                           Adopted by the Board of Directors of
                                           the Company on January 18, 2000.

                                           Approved by the stockholders of the

                               GENERAL PROVISIONS

2.   RENT

     2.1  BASE ANNUAL RENT. Tenant shall pay the first monthly installment of
Base Annual Rent upon execution of this Lease. Tenant shall pay the remaining
monthly installments of Base Annual Rent specified in Section 1.3 in advance
without deduction or demand, on the first day of each and every calendar month
throughout the entire term of the Lease, as specified in Section 1.2, to and at
the office of Landlord's Agent, Charles E. Smith Management, Inc., 2345 Crystal
Drive, Arlington, Virginia 22202, or to such other person or at such other place
as Landlord may hereafter designate in writing.

     2.2  ADDITIONAL RENT. For purposes of computing additional rent hereunder,
the Base Year as used in this Section 2 is stipulated in Section 1.4. If dollar
amounts for Base Year real estate taxes and operating expenses are stipulated
under Section 1.4, such dollar amounts shall be used in calculating
additional rent for the purposes of this Lease and shall prevail regardless of
actual historical dollar amounts for the Base Year. Commencing on the date
specified in Section 1.5. and continuing throughout the term of this
Lease, Tenant shall pay to Landlord as additional rent each of the following:

          (a)  REAL ESTATE TAXES. Tenant's pro rata share, as indicated in
Section 1.5(a), of any increase in real estate taxes during each fiscal year of
Landlord over the Base Year real estate taxes. The term "real estate taxes"
shall mean all taxes, general and special, levied or assessed on the land and
the building improvements of which the Demised Premises is a part, and on any
land and/or improvements now or hereafter owned by Landlord that provide the
building or the Demised Premises with parking or other services.

          (b)  OPERATING EXPENSES. Tenant's pro rata share, as indicated in
Section 1.5 (b), of any increase in operating expenses during each fiscal year
of Landlord over the Base Year operating expenses.

               (i)  The term "operating expenses" shall mean any and all
expenses incurred by Landlord in connection with the servicing, operation,
maintenance and repair of the building and related interior and exterior
appurtenances of which the Demised Premises is a part, and the cost of any
services incurred in order to achieve a reduction of or to minimize the increase
in operating expenses, including without limitation, management fees, capital
expenditures for equipment or systems installed to reduce or minimize increases
in operating expenses and capital expenditures required by any governmental
ordinance, or depreciation or amortization based on the useful life expectancy
of such equipment or systems or expenditures, the cost of contesting the
validity or amount of real estate taxes, and periodic increases in ground rent
payments under any ground Lease existing at the execution of this Lease. Certain
of these expenses may be apportioned among two or more buildings in the same
complex or locality owned by Landlord and/or managed by Landlord's Agent.

               (ii) Operating expenses shall not include any of the following,
except to the extent that such costs and expenses are included in operating
expenses as described in Subsection 2.2(b)(i) above: capital expenditures and
depreciation of the building; painting or decorating of tenant space; interest
and amortization of mortgages; ground rent; compensation paid to officers or
executives of Landlord; taxes as measured by the net income of Landlord
from the operation of the building; increases in real estate taxes; and
brokerage commissions.

          (c)  CPI. A percentage of the Base Annual Rent equal to the percent
stipulated in section 1.5(c) of the percentage increase in the Index now known
as "United States Bureau of Labor Statistics, Consumer Price Index for Urban
Wage Earners and Clerical Workers," (CPI-W) for Washington, DC-MD-VA, all items
Index (1982-84=100) (hereinafter referred to as the "Index"), between the last
published Index published for each calendar year and the Index for the same
period in the year stipulated in Section 1.5(c) (hereinafter "base period"). If
such Index shall be discontinued or revised without substitution of a comparable
successor Index, the parties shall attempt to agree upon a substitute formula.
If the parties are unable to agree upon a substitute formula, then the matter
shall be determined by arbitration in accordance with the rules of the American
Arbitration Association then prevailing. Any substitute formula determined by
arbitration shall include all of the same items included in the Index effective
at the execution of this Lease and shall be so designed as to achieve a result
as close as possible to the result that would have been achieved if the
discontinued Index were available. Costs of any such arbitration shall be shared
equally by Tenant and Landlord.

          (d)  Landlord shall have the right to change its fiscal year from time
to time. If Landlord changes its fiscal year during the term of this Lease,
thereby creating a fiscal year with fewer than twelve (12) months (hereinafter
"short year"), the real estate taxes and operating expenses for the short year
shall be determined on an annualized basis by taking the monthly average of the
actual real estate taxes and operating expenses, respectively, and multiplying
each by twelve. The amounts determined by this method shall be used in
determining the increases described in Subsections 2.2(a) and (b) for the "short
year".

     2.3  ADDITIONAL RENT ESTIMATES AND ADJUSTMENTS.

          (a)  In order to provide for current monthly payments of additional
rent, Landlord shall submit to Tenant prior to January 1st of each year a
statement of Landlord's estimate of the amount of the increases described in
Section 2.2 above together with the amount of Tenant's additional rent which is
estimated to result from such increases. Commencing on the date stipulated in
Section 1.5, and continuing throughout the remaining term of this Lease, Tenant
shall pay each month one-twelfth (1/12th) of Tenant's pro rata share of
Landlord's estimate of the increase in each year for (i) real estate taxes and
(ii) operating expenses, over such items for the Base Year. In addition, Tenant
shall pay each month one-twelfth (1/12th) of Landlord's estimate of the annual
rent increase due to the percentage increase in the Consumer Price Index over
the Base Period.


                                       -4-

          (b)  If payment of additional rent begins on a date other than January
1st under this Lease, in order to provide for current payments of additional
rent through December 31st of that partial calendar year, Landlord shall submit
to Tenant a statement of Landlord's estimate of Tenant's additional rent for
that partial year, stated in monthly increments, resulting from the increases
described in Section 2.2 above. Tenant shall make these payments of estimated
additional rent together with its installments of base monthly rent.

          (c)  After the end of each calendar year, Landlord will as soon as
practicable submit to Tenant a statement of the actual increases incurred in
real estate taxes and operating expenses for the fiscal year ended during such
calendar year over such costs for the Base Year and the actual increase
attributable to the increase in the Consumer Price Index over the Base Period.
Such statement shall also indicate the amount of Tenant's excess payment or
underpayment based on Landlord's estimate. If additional rent paid by Tenant
during the preceding calendar year shall be in excess of, or less than, the
aggregate of its share of the actual increase incurred by Landlord for real
estate taxes and operating expenses, and the actual increase attributable to the
increase in the Consumer Price Index, Landlord and Tenant agree to make the
appropriate adjustment following the submission of Landlord's statement. Tenant
shall either pay any additional rent due with the installment of rent due for
the month following submission of Landlord's statement, or pay any additional
rent due within thirty (30) days if the Lease term has expired or is otherwise
terminated. Tenant shall deduct its excess payment, if any, from the installment
of rent for such month, or following the final year of the Lease term, Tenant
shall be reimbursed for any excess payments made.

          (d)  Within ten (10) days after receipt of Landlord's statement
showing actual figures for the year, Tenant shall have the right to request
copies of real estate bills and an unaudited statement of "operating expenses
of the building" prepared by Landlord's certified public accountant, which shall
be supplied to Tenant within a reasonable time after Tenant's written request.
Unless Tenant asserts specific error(s) within thirty (30) days after Landlord
has complied with Tenant's request, Tenant shall have no right to contest the
statement of actual figures for the year submitted by Landlord. No such request
shall extend the time for payments as set forth in this Section 2.3 above. If
Tenant has given proper notice, and if it shall be determined that there is an
error in Landlord's statement, Tenant shall be entitled to a credit for any
overpayment, which shall be applied to the next installment of rent or refunded
to a Tenant who has vacated the premises, or Tenant shall be billed for any
underpayment and shall remit any amount owing to Landlord within ten (10) days
of receipt of such statement.

          (e)  In the event Tenant questions the validity of the statement of
operating expenses submitted by Landlord, Tenant shall have the right to examine
or have its accountant examine at the office of Landlord's accountant the books
and records from which such statement has been prepared. No such examination
shall extend the time for payments due in accordance with this Section 2.3,
however. Tenant shall pay upon demand a reasonable sum to reimburse Landlord
for the costs of services of Landlord's accountant in cooperating and assisting
in the examination. If any error amounting to more than five (5) percent in the
operating expenses statement is found, Landlord shall bear its accountant's
costs as aforesaid.

     2.4  RENT ADJUSTMENT LIMIT. Notwithstanding any adjustments to rent as
provided for above, in no event shall the total rent to be paid by tenant in any
month during the term of this Lease or any extension thereof be less than the
base monthly rent stipulated in Section 1.3.

     2.5  SURVIVAL OF RENT OBLIGATION. The obligation of Tenant with respect to
the payment of rent, or additional rent as defined in Sections 2.2 and 2.10,
accrued and unpaid during the term of the Lease, shall survive the expiration
or earlier termination of the Lease.

     2.6  PRO RATA SHARE. Tenant's "pro rata share" stipulated in Section 1.5(a)
and (b) represents the ratio that the area of the Demised Premises bears to the
total rentable area of office space contained in the building.

     2.7  PRORATED RENT. Any rent or additional rent payable for one or more
full calendar months in a partial calendar year at the beginning or end of the
Lease term shall be prorated based upon the number of months. Any rent or
additional rent payable for a portion of a month shall be prorated based upon
the number of days in the applicable calendar month.

     2.8  APPLICATION OF RENT. No payment by Tenant or receipt by Landlord of
lesser amounts of rent or additional rent than those herein stipulated shall be
deemed to be other than on account of the earliest unpaid stipulated rent. No
endorsement or statement on any check or any letter accompanying any check or
payment as rent shall be deemed an accord and satisfaction, and Landlord may
accept such check or payment without prejudice to Landlord's right to recover
the balance of such rent or pursue any other remedy provided in this Lease. Any
credit due to Tenant hereunder by reason of overpayment of additional rent shall
first be applied to any damages or rent owed to Landlord by Tenant if Tenant
shall be in default when said credit shall be owed.

     2.9  LATE PAYMENT FEE. In the event any installment of rent or additional
rent due hereunder is not paid within ten (10) calendar days after it is due,
then Tenant shall also pay to Landlord as additional rent a late payment fee
equal to five percent (5%) of such delinquent rent for each and every month or
part thereof such rent remains unpaid.

     2.l0  OTHER TENANT COSTS & EXPENSES. All costs and expenses which Tenant
assumes or agrees to pay to Landlord pursuant to this Lease, including without
limitation costs of construction and alterations, shall be deemed additional
rent and, in the event of nonpayment thereof, Landlord shall have all the
rights and remedies herein provided for in case of nonpayment of rent,
including assessment of late payment fees.

3.   CONSTRUCTION OF PREMISES AND OCCUPANCY

     3.1  TENANT PLANS, CONSTRUCTION AND RENT LIABILITY. Tenant shall deliver to
Landlord for its approval, by the date specified in Section 1.7(a),
preliminary plans approved in writing by Tenant showing its partition,
electrical, telephone and all other requirements set forth in Tenant Plans
Guidelines (which shall have been provided by Landlord to Tenant). Tenant
preliminary plans shall permit the preparation of working drawings and cost
estimate, and shall be certified by Tenant's architects or engineers to be in
compliance with applicable building and fire codes. Landlord's approval of
Tenant plans or work does not constitute certification by Landlord that said
plans or work meet the applicable requirements of any building codes, laws,
or regulations, nor shall it impose any liability whatsoever upon Landlord. If
Tenant's plans are not in compliance with applicable building and fire codes,
they shall not be deemed acceptable to Landlord. If Tenant's plans are
acceptable to Landlord, Landlord shall have working drawings prepared. Nothing
contained in this Section 3.1, nor any delay in completing the Demised
Premises, shall in any manner affect the commencement date of this Lease set
forth in Section 1.2 or Tenant's liability for the payment of rent from such
commencement date, except as follows. If Landlord requires longer than the
number of working days stipulated in Section 1.7(b) to prepare working
drawings and prepare the cost estimate following receipt of Tenant's approved
preliminary drawings, or if Landlord requires longer than the number of
working days stipulated in Section 1.7(c) to substantially complete construction
improvements in the Demised Premises, then the date for payment of rent
covenanted and reserved to be paid herein shall be put off by one day for each
extra day Landlord requires for the foregoing preparation of working drawings
and cost estimate and/or substantial completion of construction improvements.
For purposes of this Section 3.1, substantial completion of construction
improvements shall mean when all work to be performed by Landlord pursuant to
the approved working drawings has been completed, except for minor items of work
and minor adjustments of equipment and fixtures that can be completed after
occupancy of the Demised Premises without causing undue interference with
Tenant's reasonable use of the Demised Premises (i.e., so-called "punch-list"
items). In the event Tenant's plans specify any improvements that are not
building standard, however, the delivery and installation of which precludes
Landlord from completing the Demised Premises for Tenant's occupancy by the
commencement date hereof, or in the event any work to be performed by Tenant or
Tenant's contractors delays Tenant's occupancy by the commencement date
hereof, Tenant shall nevertheless remain liable for the payment of rent from
such commencement date.

     3.2 POSSESSION. If Landlord shall be unable to tender possession of the
Demised Premises on the date of the commencement of term hereof, set forth in
Section 1.2, by reason of: (a) the fact that the premises are located in a
building being constructed and which has not been sufficiently completed to make
the premises ready for occupancy; (b) the holding over or retention of
possession of any tenant or occupant; or (c) for any other reason beyond control
of Landlord, Landlord shall not be subject to any liability for the failure to
tender possession on said date. In the case of holding over, provided Landlord
shall promptly institute suit for recovery of the premises and diligently pursue
the same, Landlord shall have no responsibility for any delay in tendering
possession of the Demised Premises. Under such circumstances the rent reserved
and covenanted to be paid herein shall not commence until possession of the
Demised Premises is tendered to Tenant. No such failure to give possession on
the date of commencement of the term shall in any other respect affect the
validity of this Lease or the obligations of Tenant hereunder, nor shall same be
construed to extend the termination date of this Lease set forth in Section
1.2. If permission is given to Tenant to enter into possession of the Demised
Premises prior to the date specified as the commencement of the term of this
Lease, Tenant covenants and agrees that such occupancy shall be deemed to be
under all the terms, covenants, conditions and provisions of this Lease, except
that Tenant shall be responsible for payment of rent, in advance, at the rate of
1/30th of the base monthly rent set forth in Section 1.3 for each day of such
occupancy prior to the date for the commencement of the term of this Lease.

     3.3 OCCUPANCY PERMITS. Tenant shall be responsible for obtaining occupancy
permits and any other permits or licenses necessary for its lawful occupancy of
the Demised Premises.

4.   SUBLETTING AND ASSIGNMENT

     4.1  CONSENT. Tenant will not sublet the Demised Premises or any part
thereof or transfer possession or occupancy thereof to any person, firm or
corporation, or transfer or assign this Lease, without the prior written consent
of Landlord, which consent shall be in Landlord's sole discretion to give or
withhold. No subletting or assignment hereof shall be effected by operation of
law or in any other manner unless with prior written consent of Landlord. Tenant
further agrees that any permitted subletting of the Demised Premises shall be
subject to the provisions of Section 4.3. No assignment shall be made except
for the entire premises demised by this Lease. Tenant further agrees that any
permitted assignment of the Lease may be conditioned upon payment of
consideration to be agreed upon by Landlord and Tenant. Any subletting or
assignment consented to by Landlord shall be evidenced in writing in a form
acceptable to Landlord. Consent by Landlord to any assignment or subletting by
Tenant shall not operate as a waiver of the necessity for obtaining Landlord's
consent in writing to any subsequent assignment or subletting; nor shall the
collection or acceptance of rent from any such assignee, subtenant or occupant
constitute a waiver or release of Tenant of any covenant or obligation
contained in this Lease. In the event that Tenant defaults under this Lease in
the payment or rent or additional rent, Tenant hereby assigns to Landlord the
rent due from any subtenant of Tenant and hereby authorizes each such
subtenant to pay said rent directly to Landlord.

     4.2  RECAPTURE OF PREMISES. In the event Tenant desires to sublet the
Demised Premises or assign the Lease, Tenant shall give the Landlord written
notice of Tenant's intended subtenant or assignee in order to secure Landlord's
written consent in accordance with Section 4.1. Within ninety (90) days of
receipt of said notice, Landlord shall have the right: (i) to terminate this
Lease by giving Tenant not less than thirty (30) days' notice in the case of an
assignment of the entire Lease or a subletting of more than fifty percent (50%)
of the Demised Premises; or (ii) to) terminate this Lease and simultaneously
to enter into a new Lease with


                                       -6-
<PAGE>   10



Tenant for that portion of the Demised Premises Tenant may desire to retain upon
the same terms, covenants and conditions of the existing Lease as applicable to
the space retained. If Landlord exercises its right to terminate this Lease,
Tenant agrees that Landlord shall have access to all or a portion of the
Demised Premises sixty (60) days prior to the effective termination date for
remodeling or redecorating purposes.


     4.3  EXCESS RENT. In the event Landlord does not exercise its right to
terminate this Lease, and Landlord has granted its written consent, Tenant may
sublet all or a portion of the Demised Premises. Any rent accruing to Tenant as
the result of such sublease, which is in excess of the pro rata share of rent
then being paid by Tenant for the portion of the Demised Premises being
sublet, shall be paid by Tenant to Landlord monthly as additional rent.

     4.4  TENANT LIABILITY. In the event of any subletting of the Demised
Premises or assignment of this Lease by Tenant, with or without Landlord's
consent, Tenant shall remain liable to Landlord for payment of the rent
stipulated herein and all other covenants and conditions contained herein.

5.   SERVICES AND UTILITIES

     5.1  BUILDING STANDARD SERVICES AND UTILITIES. Landlord shall furnish
sufficient electric current for lighting and office equipment, such as
typewriters, calculators, small copiers and similar items, subject to the
limitations of Section 5.3, water for lavatory and drinking purposes, lavatory
supplies, fluorescent tube replacements, automatically operated elevator
service and nightly cleaning service in accordance with Landlord's prevailing
practices, as they may be established from time to time, except that Landlord
shall not be responsible for cleaning Tenant kitchens or private bathrooms,
Tenant rugs, carpeting and drapes. Landlord further agrees to furnish heating
and cooling during the appropriate seasons of the year, between the hours and
on the days set forth in Section 1.8 (exclusive of legal public holidays as
defined in Section 6103 (a) and (c) of Title 5 of the United States Code, as it
may be hereafter be amended, with holidays falling on Saturday observed on the
preceding Friday and holidays falling on Sunday observed on the following
Monday). All of the aforesaid services shall be provided without cost to Tenant
except as such expenses may be included in calculating the additional rent
pursuant to the provisions of Sections 2.2 and 2.3. Landlord shall not be
liable for failure to furnish, or for suspension or delays in furnishing, any
of such services caused by breakdown, maintenance or repair work, strike, riot,
civil commotion, governmental regulations or any other cause or reason whatever
beyond the control of Landlord. Suspension or interruption of services shall
not result in any abatement of rent, be deemed an eviction or relieve Tenant of
performance of Tenant's obligations under this Lease.

     5.2  OVERTIME SERVICES. Should Tenant require heating and cooling services
beyond the hours and/or days stipulated in Section 1.8, upon receipt of at
least 72 hours prior written notice from Tenant, Landlord will furnish such
additional service at the then prevailing hourly rates, as established by
Landlord from time to time; provided, further, that there will be a minimum
charge of four (4) hours each time overtime services are required.

     5.3  EXCESSIVE ELECTRICAL USAGE.

          (a)  Tenant will not install or operate in the Demised Premises any
heavy duty electrical equipment or machinery without first obtaining prior
written consent of Landlord. Landlord may, among other conditions, require
as a condition to its consent for the installation of such equipment or
machinery, payment by Tenant as additional rent for excess consumption of
electricity that may be occasioned by the operation of said equipment or
machinery. Landlord may make periodic inspections of the Demised Premises at
reasonable times to determine that Tenant's electrically operated equipment
and machinery complies with the provisions of this Section and Section
5.4.

          (b)  The total average consumption of electricity, including lighting,
in excess of five (5) watts per square foot for the Demised Premises shall be
deemed excessive. Additionally, any individual piece of electrically operated
machinery or equipment having a name plate rating in excess of two (2) kilowatts
shall also be deemed as requiring excess electric current.

          (c)  Landlord may require that one or more separate meters be
installed to record the consumption or use of electricity, or shall have the
right to cause a reputable independent electrical engineer to survey and
determine the quantity of electricity consumed by such excessive use. The cost
of any such survey or meters and of installation, maintenance and repair
thereof shall be paid for by Tenant. Tenant agrees to pay Landlord (or the
utility company, if direct service is provided by the utility company),
promptly upon demand therefor, for all such electric consumption and
demand as shown by said meters, or a flat monthly charge determined by the
survey, as applicable, at the rates charged for such service by the local
public utility company. If Tenant's cost of electricity based on meter
readings is to be paid to Landlord, Tenant shall pay a service charge related
thereto.

     5.4  EXCESSIVE HEAT GENERATION. Landlord shall not be liable for its
failure to maintain comfortable atmospheric conditions in all or any portion of
the Demised Premises due to heat generated by any equipment, machinery or
additional lighting installed by Tenant (with or without Landlord's consent)
that exceeds design capabilities for the building of which the Demised Premises
are a part. If Tenant desires additional cooling to offset excessive heat
generated by such equipment or machinery, Tenant shall pay for auxiliary
cooling equipment, and its operating costs including without limitation
electricity, gas, oil and water, or for excess electrical consumption by the
existing cooling system, as appropriate.


                                       -7-

     5.5  SECURITY. Any security measures that Landlord may undertake, are for

municipal regulations and for no other purpose whatsoever.

     6.2  ILLEGAL AND PROHIBITED USES. Tenant will not use or permit the
Demised Premises or any part thereof to be used for any disorderly, unlawful or
extra hazardous purpose and will not manufacture any commodity therein. Tenant
will not use or permit the Demised Premises to be used for any purposes that
interfere with the use and enjoyment by other tenants of the building
nor which, in Landlord's opinion, impair the reputation or character of the
building of which the Demised Premises form a part. Tenant shall refrain from
and discontinue such use upon receipt of written notice from Landlord or
no later than three (3) days after mailing thereof.

     6.3  INSURANCE RATING. Tenant will not do or permit anything to be done in
the Demised Premises or the building of which they form a part or bring or keep
anything therein which shall in any way increase the rate of fire or other
insurance in said building, or on the property kept therein, or obstruct, or
interfere with the rights of other tenants, or in any way injure or annoy them,
or those having business with them, or conflict with them, or conflict with the
fire laws or regulations, or with any insurance policy upon said building or
any part thereof, or with any statutes, rules or regulations enacted or
established by the appropriate governmental authority.

     6.4  ALTERATIONS.

          (a)  Tenant will not make any alterations, installations, changes,
replacements, repairs, additions or improvements (structural or otherwise) in or
to the Demised Premises or any part thereof, without the prior written consent
of Landlord. All Tenant plans and specifications shall be submitted to Landlord
for prior approval. Landlord may, among other things, condition its consent upon
Tenant's agreement that any construction up-gradings required by any
governmental authority as a the result of Tenant's work, either in the Demised
Premises or in any other part of the building, will be paid for by Tenant.
Tenant shall not install any equipment of any kind or nature whatsoever which

prior written consent of Landlord, and then only as Landlord may direct. Tenant

air-conditioning supply, return or control systems without the prior written
consent of Landlord, and then only as Landlord may direct. Landlord may
condition its consent upon Tenant's payment of all costs to make such changes,
replacement or modifications. Landlord's consent to any work by Tenant or
approval of Tenant plans or specifications shall not be deemed a certification
that such work complies with applicable building codes, laws or regulations, nor
shall it impose any liability whatsoever upon Landlord.

          (b)  All of Tenant's approved work shall be done in accordance with
Landlord's Supplemental Rules and Regulations for Contractors and shall be done
by duly licensed contractors in accordance with all applicable laws, codes,
ordinances, rules and regulations, and Tenant shall obtain at its cost any
required permits, licenses or inspections for performance of its work. Tenant
must obtain an executed waiver of lien from each contractor or vendor that
will perform or furnish to Tenant work, labor, services or materials for any
alterations, installations, replacements, additions or improvements in or to the
Demised Premises, prior to the commencement of such work. Notwithstanding the
aforesaid, if any mechanic's lien shall at any time, whether before, during
or after the Lease term, be filed against any part of the building by reason to
work, labor, services or materials performed for or furnished to Tenant, Tenant
shall forthwith cause the lien to be discharged of record or bonded off to the
satisfaction of Landlord. If Tenant shall fail to cause such lien to be
discharge or bonded off within five (5) days after being notified of the filing
thereof, then, in addition to any other right to remedy of Landlord, Landlord
may discharge the lien by paying the amount claimed to be due. The amount
paid by Landlord, and all costs and expenses, including reasonable attorney's
fees incurred by Landlord in procuring the discharge of the lien, shall be
due and payable by Tenant to Landlord as additional rent on the first day of
the next following month, or if the Lease term has expired, upon demand.

          (c)  All alterations, installations, including without limitation wall

repairs, additions, or improvements to or within the Demised Premises (whether
with or without Landlord's consent), shall at the election of Landlord remain
upon the Demised Premises and be surrendered with the Demised Premises at the
expiration of this Lease without disturbance, molestation or injury. Should
Landlord elect that alterations, installations, changes, replacements, repairs,
additions to or improvements made by or for Tenant upon the Demised Premises
be removed upon termination of this Lease or upon termination of any renewal
period hereof, Tenant hereby agrees that Landlord shall have the right to cause
same to be removed at Tenant's sole cost and expense. Tenant hereby agrees to
reimburse Landlord for the cost of such removal together with the cost of
repairing any damage

                                       -8-
<PAGE>   12


resulting therefrom, and the cost of restoring the premises to its condition and
commencement of the term of this Lease as initially improved by Landlord.
Approximately sixty (60) days prior to Tenant's scheduled vacation of the
Demised Premises, Landlord and Tenant shall meet to decide what items shall be
removed and what items shall remain. At such time Tenant shall deposit with
Landlord an amount equal to the estimated costs of removal and/or restoration of
the Demised Premises, which work shall be performed by or for Landlord at
Tenant's expense.

              (d) In the event that either Landlord or Tenant, during the term
hereby demised, shall be required by the order or decree of any court, or any
other governmental authority, or by law, code or ordinance, to repair, alter,
remove reconstruct, or improve any part of the Demised Premises or of the
building of which said premises are a part, then Tenant shall make or Tenant
shall be required to permit Landlord to perform such repairs, alterations,
removals, reconstructions, or improvements without effect whatsoever to the
obligations or covenants of Tenant herein contained, and Tenant hereby waives
all claims for damages or abatement of rent because of such repairing,
alteration, removal, reconstruction, or improvement.

common areas located in the building, including external and structural parts of
the building that do not comprise a part of the Demised Premises and are not
Leased to others. Such maintenance shall be provided without cost to Tenant
except as such expenses may be included in calculating the additional rent
pursuant to the provisions of Sections 2.2 and 2.3.

       6.6    SIGNS & ADVERTISING. No sign, advertisement or notice shall be
inscribed, painted or affixed on any part of the outside of the building, or
inside of the Demised Premises where it may be visible from the public areas of
the building, except on the directories and doors of offices, and then only in
such size, color and style as Landlord shall approve. Landlord shall have the
right to prohibit any advertisement or publication of Tenant on-or off-premises
which in Landlord's opinion tends to impair the reputation or character of the
building, Landlord or its agent. Tenant shall refrain from and discontinue such
advertisement or publication upon receipt of written notice from Landlord or no
later than three (3) days after mailing hereof.

       6.7    EXCESSIVE FLOOR LOAD. Landlord shall have the right to prescribe

Tenant's agents, employees, invitees and guests, faithfully keep, observe and
perform the Building Rules and Regulations set forth in Exhibit C, attached
hereto and made a part hereof, and such other reasonable rules and regulations

use of the Demised Premises, which in Landlord's judgment are needful for the
general well being, operation and maintenance of the Demised Premises and the
building of which they are a part, together with their appurtenances, unless
waived in writing the Landlord. In addition to any other remedy provided for
herein, Landlord shall have the right to impose a fine of $200 per incident for
violations of Building Rules and Regulations. Nothing contained in this
Lease shall be construed to impose upon Landlord any duty or obligation to

shall not be liable to Tenant for violation of the same by any other tenant, its
employees, agents, business invitees, licensees, customers, clients family

Tenant will keep the Demised Premises and the fixtures and equipment therein in
good order and condition, will suffer no waste or injury thereto, and will, at
the expiration or other termination of the term hereof, surrender and deliver

by Tenant or by Landlord on behalf of Tenant, shall be the sole responsibility
of Tenant, and Landlord shall have no obligation in connection therewith.
Notwithstanding the provisions hereof, in the event that repairs required to

Tenant provides Landlord with a means of access to the demised premised for
emergency and routine maintenance purposes. Unless access to the Demised
Premises is provided during the hours when cleaning service is normally
rendered, Landlord shall not be responsible for providing such service to the
Demised Premises or to those portions thereof which are inaccessible. Such
inability by Landlord to provide cleaning services to inaccessible areas shall
not entitle Tenant to any adjustment in rent.

8.     LIABILITY

       8.1    PERSONAL PROPERTY. All personal property of Tenant in the Demised
Premises or in the building of which the Demised Premises is a part shall be at

misappropriation is directly attributable to the negligence of Landlord, its
agents or employees. Landlord shall not be liable for any accident to or damage
to property of Tenant resulting from the use or operation of elevators or of the

the negligence of Landlord, its agents or employees. Landlord shall not, in any
event, be liable for damages to property resulting from water, steam or other

Landlord shall not be liable in damages, nor shall this Lease be affected, for
conditions arising or resulting, and which affect the building of which the
Demised Premises is a part, due to construction on contiguous premises.

       8.2    CRIMINAL ACTS OF THIRD PARTIES. Landlord shall not be liable in

damages and the expense of defending all claims made by Tenant's employees,
agents, invitees, or visitors arising out of such acts.

       8.3    PUBLIC LIABILITY. Landlord assumes no liability or responsibility
whatsoever with respect to the conduct and operation of the business to be
conducted upon the Demised Premises. Landlord shall not be liable for any
accident to or injury to any person or persons or property in or about the
Demised Premises which are caused by the conduct and operation of said business
or by virtue of equipment or property of Tenant in said premises. Tenant agrees
to hold Landlord harmless against all such claims, and indemnify Landlord from
all damages and the expense of defending all such claims.

       8.4    TENANT INSURANCE.

              (a) Tenant at its cost shall maintain as named insured, during
the term of this Lease, public liability and property damage insurance with at
least a single combined liability and property damage limit of $1,000,000.00,
insuring against all liability of Tenant and its authorized representatives
arising out of and in connection with Tenant's use or occupancy of the
premises. All public liability insurance and property damage insurance
shall insure performance by Tenant of the indemnity provisions of Section
8.1, 8.2 and 8.3. Landlord and Landlord's Agent shall be named as additional
insureds. The policy shall contain cross-liability endorsements, and an
assummed contractural liability endorsement that refers expressly to this Lease.


                                      -10-
<PAGE>   14
              (b) Tenant at its cost shall maintain as named insured, during the
term of this Lease, fire and extended coverage insurance of the Demised Premises
and its contents, including any Leasehold improvements made by Tenant, in an
amount sufficient so that no co-insurance will be payable in case of loss.

              (c) Tenant shall increase its insurance coverage as required not
more frequently than each three (3) years, if in the opinion of the mortgagee of
the building or Landlord's insurance agent the amount of public liability and
property damage insurance coverage at that time is not adequate.

              (d) All insurance required under this Lease shall be insurance
companies authorized to do business in the jurisdiction where the building of
which the Demised Premises is a part is located. Such companies shall have a
policyholder rating of at least "A" and be assigned a financial size category of
a least "Class XIV" as rated in the most recent edition of "Best's Key Rating
Guide" for insurance companies. Each policy shall contain an endorsement
requiring 30 days' written notice from the insurance company to Landlord
before cancellation or any charge in the coverage, scope or amount of any
policy. Each policy, or a certificate showing it is in effect, together with
evidence of payment of premiums, shall be deposited with Landlord at least
thirty (30) days prior to the expiration date of any policy.

              (e) Notwithstanding the fact that any liability of Tenant to
Landlord may be covered by Tenant's insurance, Tenant's liability shall in no
way be limited by the amount of its insurance recovery.

9.     DAMAGE

       9.1    DAMAGES CAUSED BY TENANT. Subject to the provision of Section 9.2,
all injury to the Demised Premises and other portions of the building of which
it is a part, caused by Tenant, its agents, employees, invitees and visitors,
will be repaired by Landlord at the expense of Tenant, except as otherwise
provided in Section 6.11, or repaired by Tenant with Landlord's approval in
accordance with Section 6. Tenant shall reimburse Landlord for such repairs
within ten (10) days of receipt of invoice from Landlord of the costs. At its
election, Landlord may regard the same as additional rent, in which event the
cost shall become additional rent payable with the installment of rent next
becoming due after notice is received by Tenant from Landlord. This provision
shall be construed as an additional remedy granted to Landlord and not in
limitation of any other rights and remedies which Landlord has or may have in
said circumstances.

       9.2    FIRE OR CASUALTY DAMAGE. In the event of damage or destruction of
the Demised Premises by fire or any other casualty without the fault or neglect
of Tenant, its agents, employees, invitees or visitors, this Lease shall not
be terminated, but structural damage to the premises including demising
partitions and doors shall be promptly and fully repaired and restored as the
case may be by Landlord at its own cost and expense. Due allowance, however,
shall be given for reasonable time required for adjustment and settlement of
insurance claims, and for such other delays as may result from government
restrictions, and controls on construction, if any, and for strikes, national
emergencies and other conditions beyond the control of Landlord. Restoration by
Landlord shall not include replacement of furniture, equipment or other items
that do not become part of the building or any improvements to the Demised
Premises in excess of those provided for as building standard items as of the
commencement date of this Lease. Tenant shall be responsible for the repair and
restoration of the Demised Premises and Tenant's property beyond Landlord's
obligation at no cost to Landlord, in accordance with the provisions of Section
6, for which it shall maintain adequate insurance pursuant to Section 8.4
herein. In the event of fire or casualty damage to the Demised Premises caused
by the fault or neglect of Tenant, its agents, employees, invitees or visitors,
Landlord shall restore structural damages as described herein at Tenant's cost
and expense. It is agreed that in any of the aforesaid events, this Lease
shall continute in full force and effect.

       9.3    UNTENANTABILITY. If the condition referred to in Section 9.2 is
such so as to make the entire premises untenantable, then the rental which
Tenant is obligated to pay hereunder shall abate as of the date of the
occurrence until the premises have been fully and completely restored by
Landlord. Any unpaid or prepaid rent for the month in which said condition
occurs shall be prorated. If the premises are partially damaged or
destroyed, then during the period that Tenant is deprived of the use of the
damaged portion of said premises, Tenant shall be required to pay rental
covering only that part of the premises that it is able to occupy, based on the
portion of the total rent which the amount of square foot area remaining that
can be occupied bears to the total square foot area of all premises covered
by this Lease. In the event the premises are substantially or totally
destroyed by fire or other casualty so as to be entirely untenantable, and
it shall require more than ninety (90) days from the date of said fire or
other casualty for Landlord to complete restoration of same, then Landlord,
upon written notice to Tenant, may terminate this Lease, in which case the
rent shall be apportioned and paid to the date of said fire or other
casualty. Due allowance, however, shall be given for reasonable time
required for adjustment and settlemnent of insurance claims, and for such
other delays as may result from government restrictions, and controls on
construction, if any, and or strikes, national emergencies and other conditions
beyond the control of Landlord. No compensation, or claim, or diminution of
rent will be allowed or paid by Landlord, by reason of inconvenience,
annoyance, or injury to business, arising from the necessity of repairing the
Demised Premises or any portion of the building of which they are a
part.

10.    CONDEMNATION

       10.1   LANDLORD RIGHTS TO AWARD. Tenant agrees that if the whole or a
substantial part of the Demised Premises shall be taken or condemned for
public or quasi-public use or purpose by any competent authority, Tenant
shall have no claim against Landlord and shall not have any claim or right
to any portion of the amount that may be awarded as damages paid as a result of
any such condemnation. All rights of


                                      -11-
<PAGE>   15


Tenant to damages (therefore if any), are hereby assigned by Tenant to Landlord.
Upon such condemnation or taking, the term of this Lease shall cease and
terminate from the date of such government taking or condemnation. If a portion
of the building or the Demised Premises is taken or condemned, and the remainder
in Landlord's opinion is not economically usable, Landlord shall notify Tenant
of the termination of this Lease effective as of the date of such governmental
taking or condemnation. Tenant shall have no claim against Landlord for the
value for any unexpired term of this Lease. If less than a substantial part of
the Demised Premises is taken or condemned by any governmental authority for
public or quasi-public use or purpose and the remainder is usable by Tenant,
the rent shall be equitably adjusted on the date when title vests in such
governmental authority and the Lease shall otherwise continue in full force
and effect. For the purposes of this Section 10, a substantial part of the
Demised Premises shall be considered to have been taken if more than fifty
percent (50%) of the Demised Premises are unusable by Tenant.

       10.2   TENANT RIGHT TO FILE CLAIM. Nothing in Section 10.1 shall preclude
Tenant from filing a separate claim against the condemning authority for the
undepreciated value of its Leasehold improvements and relocation expenses,
provided that any award to Tenant will not result in a diminution of any award
to Landlord.

11.    BANKRUPTCY

       11.1   EVENTS OF BANKRUPTCY. The following shall be Events of Bankruptcy
under this Lease:

              (a) Tenant's becoming insolvent, as the term is defined in Title
11 of the United States Code, entitled Bankruptcy, 11 U.S.C. Sec. 101 et seq.
(the "Bankruptcy Code"), or under the insolvency laws of any State, District,
Commonwealth or Territory of the United States ("Insolvency Laws");

              (b) The appointment of a receiver or custodian for any or all of
Tenant's property or assets, or the institution of a foreclosure action upon
any of Tenant's real or personal property;

              (c) The filing of a voluntary petition under the provisions of
the Bankruptcy Code or Insolvency Laws;

              (d) The filing of an involuntary petition against Tenant as the
subject debtor under the Bankruptcy Code or Insolvency Laws, which is either not
dismissed within thirty (30) days of filing, or results in the issuance of an
order for relief against the debtor, whichever is later; or

              (e) Tenant's making or consenting to an assignment for the
benefit of creditors of a common law composition of creditors.

       11.2   LANDLORD'S REMEDIES.

              (a) Termination of Lease. Upon occurrence of an Event of
Bankruptcy, Landlord shall have the right to terminate this Lease by giving
written notice to Tenant; provided, however, that this Section 11.2(a) shall
have no effect while a notice in which Tenant is the subject debtor under
the Bankruptcy Code is pending, unless Tenant or its Trustee is unable to
comply with the provisions of Section 11.2(d) and (e) below. At all other times
this Lease shall automatically cease and terminate, and Tenant shall be
immediately obligated to quit the premises upon the giving of notice
pursuant to this Section 11.2(a). Any other notice to quit, or notice of
Landlord's intention to re-enter is hereby expressly waived. If Landlord
elects to terminiate this Lease, everything contained in this Lease on the
part of Landlord to be done and performed shall cease without prejudice,
subject, however, to the rights of Landlord to recover from Tenant all rent
and other sums accrued up to the time of termination or recovery of
possession by Landlord, whichever is later, and any other monetary
damages or loss of reserved rent sustained by Landlord.

              (b) Suit for Possession. Upon termination of this Lease
pursuant to Section 11.2(a), Landlord may proceed to recover possession under
and by virtue of the provisions of the laws of any applicable jurisdiction,
or by such other proceedings, including reentry and possession, as may be
applicable.

              (c) Non-Exclusive Remedies. Without regard to any action by
Landlord as authorized by Section 11.2(a) and (b) above, Landlord may at its
discretion exercise all the additional provisions set forth below in Section 12.

              (d) Assumption or Assignment by Trustee. In the event Tenant
becomes the subject debtor in a case pending under the Bankruptcy Code,
Landlord's right to terminate this Lease pursuant to Section 11.2(a) shall be
subject to the rights of the Trustee in Bankruptcy to assume or assign this
Lease. The Trustee shall not have the right to assume or assign this Lease
unless the Trustee (i) promptly cures all defaults under this Lease, (ii)
promptly compensates Landlord for monetary damages, incurred as a result of
such default, and (iii) provides adequate assurance of future performance
on the part of Tenant as debtor in possession or on the part of the
assignee Tenant.

              (e) Adequate Assurance of Future Performance. Landlord and Tenant
hereby agree in advance that adequate assurance of future performance, as used
in Section 11.2(d) above, shall mean that all of the following minimium criteria
must be met: (i) Tenant's gross receipts in the ordinary course of business
during the thirty-day period immediately preceding the initiation of the
case under the Bankruptcy Code must be at least two times greater than the
next payment of rent due under this Lease; (ii) Both the average and median
of Tenant's gross receipts in the ordinary course of business during the
six-month period immediately preceding the initiation of the case under
the Bankruptcy Code must be at least two times greater than the next
payment of rent due under this Lease; (iii) Tenant must pay its estimated
pro rata share of cost of all


                                      -12-
<PAGE>   16

services provided by Landlord (whether directly or through agents or contractors
and whether or not previously included as part of the base rent), in advance of
the performance or provision of such services; (iv) The Trustee must agree that
Tenant's business shall be conducted in a first class manner, and that no
liquidating sales, auctions, or other non-first class business operations shall
be conducted on the premises; (v) The Trustee must agree that the use of the
premises as stated in this Lease will remain unchanged and that no prohibited
use shall be permitted; and (vi) The Trustee must agree that the assumption or
assignment of this Lease will not violate or affect the rights of other tenants
in the building.

              (f) Failure to Provide Adequate Assurance. In the event Tenant is
unable to (i) cure its defaults, (ii) reimburse the Landlord for its monetary
damages, (iii) pay the rent due under this Lease, and all other payments
required of Tenant under this Lease on time (or within five (5) days), or (iv)
meet the criteria and obligations imposed by Section 11.2(e) above, Tenant
agrees in advance that it has not met its burden to provide adequate assurance
of future performance, and this Lease may be terminated by Landlord in
accordance with Section 11.2(a) above.

12.    DEFAULTS & REMEDIES

       12.1   DEFAULT. It is agreed that Tenant shall be in default if: Tenant
shall fail to pay the rent, or any installments thereof as aforesaid, at the
time shall become due and payable and/or any additional rent as herein provided
although no demand shall have been made for the same; or Tenant shall violate or
fail or neglect to keep and perform any of the covenants, conditions and
agreements, or rules and regulations herein contained on the part of Tenant
to be kept and performed.

       12.2   REMEDIES. In each and every such event set forth in Section 12.1
above, from thenceforth and at all times thereafter, at the option of Landlord,
Tenant's right of possession shall thereupon cease and terminate, and Landlord
shall be entitled to the possession of the Demised Premises and to re-enter the
same without demand of rent or demand of possession of said premises and may
forthwith proceed to recover possession of the Demised Premises by process of
law, any notice to quit being hereby expressly waived by Tenant. In the event of
such re-entry by process of law or otherwise, Tenant nevertheless agrees to
remain answerable for any and all damage, deficiency or loss of rent which
Landlord may sustain by such re-entry, including reasonable attorney's fees and
court costs. If, under the provisions hereof, seven (7) days summons or other
applicable summary process shall be served, and a compromise or settlement
therefor shall be made, such action shall not be constituted as a waiver of any
breach of any covenant, condition or agreement herein contained. No waiver of
any breach of any covenant, condition or agreement, herein contained, on one or
more occasions shall operate as a waiver of the covenant, condition or agreement
itself, or of any subsequent breach thereof. No provision of this Lease shall be
deemed to have been waived by Landlord unless such waiver shall be in writing
signed by Landlord.

       12.3   LANDLORD'S RIGHT TO RELET. Should this Lease be terminated before
the expiration of the term of this Lease by reason of Tenant's default as
provided in Section 11 or 12, or if Tenant shall abandon or vacate the premises
before the expiration or termination of the term of this Lease, the Demised
Premises may be relet by Landlord for such rent and upon such terms as are
reasonable under the circumstances. If the full rent reserved under this Lease
(and any of the costs, expenses or damages indicated below) shall not be
realized by Landlord, Tenant shall be liable for all damages sustained by
Landlord, including, without limitation, deficiency in rent, reasonable
attorney's fees, other collection costs, brokerage fees, and expenses of placing
the premises in first-class rentable condition. Landlord, in putting the
premises in good order or preparing the same for rerental may, at Landlord's
option, make such alterations, repairs, or replacements in the premises, and the
making of such alterations, repairs, or replacements in the premises as
Landlord, in Landlord's sole judgment, considers advisable and necessary for the
purpose of reletting the premises, and the making of such alternations, repairs,
or replacements shall not operate or be construed to release Tenant from
liability hereunder as aforesaid. Landlord shall in no event be liable in any
way whatsoever for failure to relet the premises, or in the event that the
premises are relet, for failure to collect the rent thereof under such
reletting. In no event shall Tenant be entitled to receive any excess, if any,
of such net rent collected over the sums payable by Tenant to Landlord
hereunder.

       12.4   RECOVERY OF DAMAGES. Any damage or loss of rent sustained by
Landlord may be recovered by Landlord, at Landlord's option, in separate
actions, from time to time, as said damage shall have been ascertained or, at
Landlord's option, may be deferred until the expiration of the term of this
Lease (in which event Tenant hereby agrees that the cause of action shall not be
deemed to have accrued until the date of expiration of said term). The
provisions contained in this paragraph shall be in addition to and shall not
prevent the enforcement of any claim Landlord may have against Tenant for
anticipatory breach of the unexpired term of this Lease. All rights and
remedies of Landlord under this Lease shall be cumulative and shall not be
exclusive of any rights and remedies provided to Landlord under applicable law.
In the event Tenant becomes the subject debtor in a case under the Bankruptcy
Code, the provisions of this Section 12.4 may be limited by the limitations
of damage provisions of the Bankruptcy Code.

       12.5   WAIVER. If under the provisions hereof Landlord shall institute
proceedings and a compromise or settlement thereof shall be made, the same shall
not constitute a waiver of any covenant, rule or regulation herein contained nor
of any of Landlord's rights hereunder. No waiver by Landlord of any breach of
any covenant, condition, agreement, rule or regulation herein contained shall
operate as a waiver of such covenant, condition, agreement, rule or regulation
itself, or of any subsequent breach thereof.


                                      -13-
<PAGE>   17


       12.6   ANTICIPATORY  REPUDIATION. If, prior to the commencement of the
term of this Lease, Tenant notifies Landlord of or otherwise unequivocally
demonstrates as intention to repudiate this Lease, Landlord may, at its option,
consider such anticipatory repudiation a breach of this Lease. In addition to
any other remedies available to it hereunder or at law or in equity, Landlord
may retain all rent paid upon execution of the Lease and the security deposit,
if any, shall be applied to Landlord's damages: reletting, loss of rent, etc. It
is agreed between the parties that for the purpose of calculating Landlord's
damages, in a building which has other available space at the time of Tenant's
breach, the premises covered by this Lease shall be deemed the last space
rented, even though the premises may be rerented prior to such other vacant
space. Tenant shall pay in full for all tenant improvements constructed or
installed within the Demised Premises to the date of the breach, and for
materials ordered at its request for the Demised Premises.

       12.7   TENANT ABANDONMENT OF PREMISES.

              (a) Abandonment. If the Demised Premises shall be deserted or
vacated by Tenant for thirty (30) consecutive days or more without notice to
Landlord, and Tenant shall have failed to make the current rental payment, the
premises may be deemed abandoned. Landlord may consider Tenant in default
under this Lease and may pursue all remedies available to it under this Lease or
at law.

              (b) Landlord Right to Enter and to Relet. If Tenant vacates or
abandons the premises as defined above, Landlord may, at its option, enter into
the premises without being liable for any prosecution therefor or for damages by
reason thereof. In addition to any other remedy, Landlord, as agent of Tenant,
may relet the whole or any part of the premises for the whole or any part of the
then unexpired Lease term. For the purposes of such reletting, Landlord may make
any alterations or modifications of the premises considered desirable in its
sole judgment.

              (c) Rights to Dispose of Tenant Property. If Tenant vacates or
abandons the premises as defined above, any property that Tenant leaves on the
premises shall be deemed to have been abandoned and may either be retained by
Landlord as the property of Landlord or may be disposed of at public or private
sale in accordance with applicable law as Landlord sees fit. The proceeds of any
public or private sale of Tenant's property, or the then current fair market
value of any property retained by Landlord, shall be applied by Landlord against
(i) the expenses of Landlord for removal, storage or sale of the property; (ii)
the arrears of rent or future rent payable under this Lease; and (iii) any
other damages to which Landlord may be entitled hereunder.

              (d) Transfer of Tenant Property to Creditors. If Tenant vacates or
abandons the premises, as defined above, Landlord may, upon presentation of
evidence of a claim valid upon its face of ownership or of a security interest
in any of Tenant's property abandoned in the premises, turn over such property
to the claimant with no liability to Tenant.

13.    SUBORDINATION

       13.1   SUBORDINATION. This Lease is subject and subordinate to all ground
or underlying Leases and to all mortgages and/or deeds of trust and/or other
security interests which may now or hereafter affect the real property of which
the Demised Premises form a part, and to all renewals, modifications,
consolidations, replacements and extensions thereof. This clause shall be
self-operative and no further instrument of subordination shall be required to
effect this subordination. Notwithstanding the foregoing, in confirmation of
such subordination, Tenant shall at Landlord's request execute and deliver to
Landlord within ten (10) business days after Landlord's request, any requisite
or appropriate certificate, subordination agreement or other document that may
be reasonably requested by Landlord or any other party requiring such
certificate, subordination agreement or document. If Tenant fails to execute
such certificate, subordination agreement or other document within said ten (10)
day period, Tenant by such failure irrevocably constitutes and appoints Landlord
as its special attorney-in-fact to execute such certificate, subordination
agreement or other document on Tenant's behalf. Notwithstanding the foregoing
subordination, Tenant agrees that any landlord under any ground or underlying
Lease, and any mortgagee or trustee under any security agreement to which this
Lease is now, or may hereafter, become subject or subordinate, may elect to
continue this Lease and Tenant agrees that in such event neither the
cancellation nor termination of any ground or underlying Lease, nor the
foreclosure under any mortgage or deed of trust, nor the sale at foreclosure,
nor the transfer by a deed in lieu of foreclosure, shall, by operation of law or
otherwise, result in cancellation or termination of this Lease or the
obligations of Tenant hereunder and this Lease shall continue as a direct Lease
between Tenant and such landlord, mortgagee, purchaser or trustee.

       13.2   ESTOPPEL CERTIFICATES. Tenant shall execute and return within ten
(10) business days any certificate that Landlord may request from time to time,
stating that this Lease is unmodified and in full force and effect, or in full
force and effect as modified, and stating the modification. The certificate also
shall state (a) the amount of base monthly rent and the dates to which the rent
has been paid in advance; (b) the amount of any security deposit or prepaid
rent; (c) that there is no present default on the part of Landlord, or attach a
memorandum stating any such instance of default; (d) that Tenant has no right
to setoff and no defense or counterclaim against enforcement of its obligations
under this Lease; (e) that Tenant has no other notice of any sale, transfer or
assignment of this Lease or of the rentals; (f) that all work required of
Landlord has been completed and that the work is accepted as satisfactory; (g)
that Tenant is in full and complete possession of the Demised Premises; (h)
the date on which rent commenced and the date to which it is paid; (i) that
Tenant has not advanced any amounts to or on behalf of Landlord which have not
been reimbursed; (j) that Tenant understands that this Lease has been
collaterally assigned to Landlord's mortgagee as security for a loan to
Landlord; (k) that rent may not be prepaid without the prior written approval of
Landlord's mortgagee; and


                                      -14-
<PAGE>   18


(l) such other items as Landlord may reasonably request. Failure to deliver the
certificate within the ten (10) business days shall be (conclusive) upon Tenant
for the benefit of Landlord and any successor to Landlord that this Lease is in
full force and effect and has not been modified except as may be represented by
the party requesting the certificate. If Tenant fails to deliver the certificate
within the ten (10) business days, Tenant by such failure irrevocably
constitutes and appoints Landlord as its special attorney-in-fact to execute and
deliver the certificate to any third party.

       13.3   ATTORNMENT. Tenant covenants and agrees that, in the event of any
foreclosure under any mortgage or deed of trust, or any renewal, modification,
consolidation, replacement or extension thereof, or in the event of any
acceptance of any deed in lieu of foreclosure, which may now or hereafter affect
the real property of which the Demised Premises are a part, Tenant shall attorn
to the party secured by such mortgage or deed of trust, or any renewal,
modification, consolidation, replacement or extension thereof, and to any
purchaser at any foreclosure sale or party taking a deed in lieu of foreclosure.
Tenant covenants and agrees to attorn to any successor to Landlord's interest in
any ground or underlying Lease. In any case, such landlord or successor under
such ground or underlying Lease or such secured party or purchaser at
foreclosure sale or party taking a deed in lieu of foreclosure shall not be
bound by any prepayment on the part of Tenant of any rent for more than one
month in advance, so that rent shall be payable under this Lease in accordance
with its terms, from the date of the termination or transfer of the ground or
underlying Lease or the foreclosure under such mortgage or deed of trust, or the
date of foreclosure sale or transfer by deed in lieu of foreclosure, as if such
prepayment had not been made. Further, such landlord or successor in interest
shall not be liable for damages for any act or omission of Landlord or any prior
landlord or be subject to any offsets or defenses which Tenant may have against
Landlord or any prior landlord. Tenant shall, upon request of such landlord or
successor landlord, execute and deliver an instrument or instruments confirming
Tenant's attornment.

       13.4   MORTGAGEE RIGHTS.

              (a) Tenant shall, at its own expense, comply with all reasonable
notices of Landlord's mortgagee or other financial institution providing funds
which are secured by a mortgage or deed of trust placed on the whole or any part
of the real property of which the Demised Premises are a part, respecting all
matters of occupancy, use, condition or maintenance of the Demised Premises,
provided the same shall not unreasonably interfere with the conduct of Tenant's
business nor materially limit or affect the rights of the parties under this
Lease. Notwithstanding acceptance and execution of this Lease by the parties
hereto, the terms hereof shall be deemed automatically modified, if so
required, for the purpose of complying with or fulfilling the reasonable
requirements of any mortgagee or trustee named or secured by a mortgage or
deed of trust that may now or hereafter be placed upon or secured by the real
property of which the Demised Premises are a part or any part thereof, or any
other financial institution providing funds to finance or refinance the real
property of which the Demised Premises are a part, provided, however, that such
modifications(s) shall not be in material derogation or diminution of any of the
rights of the parties hereunder, nor materially increase any of the obligations
or liabilities of the parties hereunder.

              (b) Tenant agrees to give Landlord's mortgagee and any trustee
named or secured by a mortgage or deed of trust a copy of any notice of default
served upon Landlord by Tenant, provided that prior to such notice Tenant has
been notified in writing (by way of Notice of Assignment of Rents and Leases, or
otherwise) of addresses of such mortgagees and trustees. Notice shall be
provided to the mortgagees and trustees by registered mail. Tenant further
agrees that if Landlord shall have failed to cure such default within the cure
period provided in this Lease, if any, then the mortgagees and/or trustees shall
have an additional thirty (30) days within which to cure such default, or if
such default cannot be cured within that time, then such additional time as
may be necessary if within such thirty (30) days any mortgagee and/or trustee
has commenced and is diligently pursuing the remedies necessary to cure such
default (including but not limited to commencement of foreclosure proceedings
if necessary to effect such cure), in which event this Lease shall not be
terminated while such remedies are being diligently pursued.".

14.    TENANT HOLDOVER

       14.1   WITH LANDLORD CONSENT. If Tenant continues, with the knowledge and
written consent of Landlord obtained at least thirty (30) days prior to the
expiration of the term of this Lease, to remain in the premises after the
expiration of the term of this Lease, then and in that event, Tenant shall, by
virtue of this holdover agreement, become a tenant by the month at the rent
stipulated by Landlord in said holdover agreement, commencing said monthly
tenancy with the first day next after the end of the term above demised. Tenant
shall give to Landlord at least thirty (30) days' written notice of any
intention to quit said premises. Tenant shall be entitled to thirty (30) days'
written notice to quit said premises, except in the event of nonpayment of rent
in advance or of the breach of any other covenant by Tenant, in which event
Tenant shall not be entitled to any notice to quit, the usual thirty (30) days'
notice to quit being hereby expressly waived.

       14.2   WITHOUT LANDLORD CONSENT. In the event that Tenant, without the
consent of Landlord, shall hold over the expiration of the term hereby created,
then Tenant hereby waives all notice to quit and agrees to pay to Landlord for
the period that Tenant is in possession after the expiration of this Lease, a
monthly rent which is three times the total rent (base monthly rent, as
stipulated in Section 1.3, plus additional rent, as stipulated in Section 1.5)
applicable to the last month of this Lease. Tenant expressly agrees to hold
Landlord harmless from all loss and damages, direct and consequential, which
Landlord may suffer in defense of claims by other parties against Landlord
arising out of the holding over by Tenant, including without limitation
attorneys fees which may be incurred by Landlord in defense of such claims.
Acceptance of rent by Landlord subsequent to the expiration of the term of this
Lease shall not constitute consent to any holding over. Landlord shall have
the right to apply all payments received after the expiration date of this
Lease or any renewal thereof toward payment for use and occupancy of the
premises subsequent to the expiration of the term and toward any other sums owed
by Tenant to Landlord. Landlord, at its option, may forthwith re-


                                      -15-
<PAGE>   19
 enter and take possession of said premises without process, or by any legal
process in force. Notwithstanding the foregoing, Tenant's holdover without
Landlord consent due to acts of God, riot, or war shall be at the total rent
applicable to the last month of the term for the duration of the condition (but
not to exceed ten days), but such continued occupancy shall not create any
renewal of the term of this Lease or a tenancy from year-to-year, and Tenant
shall be liable for any loss and damages suffered by Landlord as described
above.

15.    SECURITY DEPOSIT

       15.1   Tenant shall deposit with Landlord simultaneously with the
execution of this Lease, the amount stipulated in Section 1.6 as a security
deposit. Provided Tenant is not in default in the payment of rent or any other
charges due Landlord, and further provided the Demised Premises are left in good
condition, reasonable wear and tear excepted, as described in Section 6.10, said
deposit (which shall not bear interest to Tenant) shall be returned to Tenant
within thirty (30) days after the termination of this Lease. If Tenant is in
default or if the premises are not left in good condition, then the security
deposit shall be applied to the extent available on account of sums due
Landlord or the cost of repairing damages to the Demised Premises. In the event
of the sale or transfer of Landlord's interest in the building, Landlord shall
have the right to transfer the security deposit to such purchaser or transferee,
in which event Tenant shall look only to the new Landlord for the return of the
security deposit and Landlord shall thereupon be released from all liability to
Tenant for the return of such security deposit.

16.    QUIET ENJOYMENT

       16.1   So long as Tenant shall observe and perform the covenants and
agreements binding on it hereunder, Tenant shall at all times during the term
herein granted, peacefully and quietly have and enjoy possession of the premises
without any encumbrance or hindrance by, from or through Landlord, except as
provided for elsewhere under this Lease. Nothing in this Section shall prevent
Landlord from performing alterations or repairs on other portions of the
building not Leased to Tenant, nor shall performance of such alterations or
repairs be construed as a breach of this covenant by Landlord.

17.    SUCCESSORS

       17.1   All rights, remedies and liabilities herein given to or imposed
upon either of the parties hereto, shall extend to their respective heirs,
executors, administrators, successors, and assigns. This provision shall not be
deemed to grant Tenant any right to assign this Lease or to sublet the premises.

18.    WAIVER OF JURY TRIAL

       18.1   Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties hereto against the
other one or in respect of any matter whatsoever arising out of or in any way
connected with this Lease, the relationship of Landlord and Tenant hereunder,
Tenants's use or occupancy of the Demised Premises, and/or any claim of "injury
or damage."

19.    LIMITATION OF LIABILITY

       19.1   Notwithstanding anything to the contrary contained in this Lease,
if any provision of this Lease expressly or impliedly obligates Landlord not to
unreasonably withhold its consent or approval, an action for declaratory
judgment or specific performance will be Tenant's sole right and remedy in any
dispute as to whether Landlord has breached such obligation.

20.    PRONOUNS & DEFINITIONS

       20.1   Feminine or neuter pronouns shall be substituted for those of the
masculine form, and the plural shall be substituted for the singular number, in

                               GENERAL PROVISIONS

2.    RENT

 2.1  BASE ANNUAL RENT

      (a) Payment of Base Annual Rent. Tenant shall pay the first monthly
installment of Base Annual Rent specified in Section 1.3 upon execution of this
Lease. After the Commencement Date, Tenant shall pay the remaining monthly
installments of Base Annual Rent in advance without deduction, demand, right of
set-off or recoupment, in immediately available funds, on the first day of each
and every calendar month throughout the entire Lease Term specified in Section
1.2(a), to Charles E. Smith Real Estate Services L.P. ("Landlord's Agent"), by
electronic funds transfer if requested by Landlord, or otherwise at the address
specified in Section 1.9(b) or 1.9(c), as applicable, or to such other person or
at such other place as Landlord may hereafter designate in writing.

      (b) Escalation of Base Annual Rent. Commencing on the first anniversary
date of the Commencement Date and continuing on each subsequent anniversary
thereof, the Base Annual Rent shall be increased by the Percentage Factor
stipulated in Section 1.3(b) times the Base Annual Rent payable for the
preceding Lease Year (all of which shall be calculated without giving effect to
any waiver of rent or rent credit otherwise provided to Tenant). The escalated
Base Annual Rent so determined shall be the "Base Annual Rent" for all purposes
of this Lease, including the calculation of the increase in Base Annual Rent for
the subsequent Lease Year.

 2.2  ADDITIONAL RENT. Commencing on the date set forth in Section 1.5 and
continuing throughout the Lease Term, Tenant shall pay as Additional Rent
Tenant's pro rata share of any (i) Real Estate Taxes and (ii) Operating
Expenses, in excess of the (i) Real Estate Taxes and (ii) Operating Expenses,
respectively, paid by Landlord in the Base Year. Additional Rent shall be
determined as follows:

      (a) Real Estate Taxes. Tenant shall pay Tenant's pro rata share, as
defined in Section 1.5(a), of any Real Estate Taxes paid during each Fiscal Year
falling entirely or partly within the Lease Term, in excess of the amount of
Real Estate Taxes paid during the Base Year.

          (i)   The term "Real Estate Taxes" shall mean (1) all taxes,
assessments (including all assessments for public improvements or benefits,
whether or not commenced or completed prior to the date hereof and whether or
not to be completed within the Lease Term), water, sewer, transportation or
other excises, levies, license fees, permit fees, impact fees, inspection fees,
and other authorization fees and other similar charges, in each case whether
general or special, levied or assessed, ordinary or extraordinary, foreseen or
unforeseen, of every character (including all interest and penalties thereon),
which at any time during or in respect of the Lease Term, may, by any
governmental or taxing authority, be assessed, levied, confirmed, or imposed on
or in respect of, or be a lien upon, the land and the building improvements of
which the Demised Premises are a part, and on any land and/or improvements now
or hereafter owned by Landlord and/or others that provide the Complex or
locality or the Demised Premises with other services, programs, amenities or
common facilities, together with (2) any other tax imposed on real estate or on
owners of real estate generally, including taxes imposed on leasehold
improvements which are assessed against the Landlord and taxes upon or with
respect to any activity conducted on the land and improvements of which the
Demised Premises are a part, upon this Lease or any rent reserved or payable
hereunder, upon the revenues or receipts from the land and improvements of which
the Demised Premises are a part, or upon the use or occupancy thereof, and (3)
to the extent the following taxes are in lieu of or a substitute for any other
taxes which are, or would be, payable by Landlord as Real Estate Taxes, (a) any
income, excess profits, or other taxes of Landlord determined on the basis of
its income, receipts, or revenues, (b) any estate, inheritance, succession,
gift, capital levy, or similar tax of Landlord, (c) any franchise, capital
stock, or similar taxes of Landlord and (d) any income, excess profits, or other
taxes of Landlord determined on the basis of its income or revenue derived
pursuant to this Lease.

          (ii)  If Real Estate Taxes paid during the Base Year are subsequently
reduced by any application or proceeding brought by or on behalf of Landlord for
reduction in the amount of Real Estate Taxes payable by Landlord, the Real
Estate Taxes deemed to have been paid during the Base Year shall be decreased
and Landlord may promptly bill Tenant for the Additional Rent not previously
paid by Tenant for any Fiscal Year during the Lease Term, based upon the reduced
amount of Real Estate Taxes deemed paid during the Base Year.

          (iii) If the Building's occupancy level is seventy percent (70%) or
less for six (6) months or more during any Fiscal Year other than the Base Year,
or if all land and improvements upon which Real Estate Taxes are or may be
assessed pursuant to Section 2.2(a)(i) above are not fully assessed during any
portion of any Fiscal Year other than any portion of the Base Year, then the
Real Estate Taxes paid during such Fiscal Year or portion thereof (other than
the Base Year) may be adjusted, at Landlord's sole option, to project the Real
Estate Taxes as if the Building were one hundred percent (100%) occupied and/or
all land and improvements are fully assessed during such Fiscal Year as
reasonably estimated by Landlord using standard accounting procedures so that
Tenant's share of the Real Estate Taxes is the amount which Tenant would bear if
the Building were fully occupied and/or if all land and improvements upon which
Real Estate Taxes may be assessed were fully assessed during the entire such
Fiscal Year. For example, if the occupancy rate for the Building during at least
six (6) months of a Fiscal Year is seventy percent (70%), and if the real estate
tax bill to Landlord is $240,000 based on the less-than-complete occupancy of
the Building, and if Landlord estimates that the Real Estate Taxes that would
have been paid if the Building had been one hundred percent (100%) occupied by
tenants would have been Three Hundred Thousand Dollars ($300,000), then Tenant
would pay as Additional Rent pursuant to Section 1.5(a) its pro rata share of
the amount by which $300,000 exceeds the Real Estate Taxes which were paid
during the Base Year.

          (iv)  In addition to the pro rata share of any increase in Real Estate
Taxes to be paid by Tenant pursuant to Sections 2.2(a)(i), (ii) and (iii) above,
Tenant shall reimburse Landlord upon demand for any and all taxes required to be
paid by Landlord upon, measured by, or reasonably attributable to the cost or
value of Tenant's Property or by the cost or value of any Leasehold Improvements
made in or to the Demised Premises by or for Tenant, regardless of whether title
to such Leasehold Improvements shall be in Tenant or Landlord, and for all taxes
required to be paid by Landlord upon, measured by, or reasonably attributable to
or with respect to the possession, leasing, operation, management, maintenance,
alteration, repair, use or occupancy by Tenant of the Demised Premises or any
portion thereof to the extent such taxes are not included in Real Estate Taxes.



                                       4

<PAGE>   55

      (b) Operating Expenses. Tenant shall pay Tenant's pro rata share, as
indicated in Section 1.5(b), of any Operating Expenses paid during each Fiscal
Year falling entirely or partly within the Lease Term, in excess of the
Operating Expenses paid during the Base Year.

          (i)   The term "Operating Expenses" shall mean any and all expenses of
Landlord in connection with the servicing, insuring, operation, maintenance,
replacement and repair of the Building and related interior and exterior
appurtenances of which the Demised Premises are a part, or for health, welfare
or safety; expenses, if any, of Landlord either alone or in conjunction with
others to maintain common facilities, amenities, programs and services required
or approved by jurisdictional authorities for the Building, the building site,
the Complex or the locality in which the Complex is situated; the cost of any
services to achieve a reduction of, or to minimize the increase in, Operating
Expenses or Real Estate Taxes; management fees; vault rentals; business license,
personal property and other taxes; capital expenditures and other costs of
Landlord for equipment or systems installed to reduce or minimize increases in
Operating Expenses or to comply with any governmental or quasi-governmental
ordinance or requirement (at the option of Landlord, such costs, with interest,
may be recovered from Tenant in installments simultaneous with the payment of
monthly installments of Base Annual Rent in accordance with a cost repayment
schedule based on the useful life of such equipment or systems). At the sole
discretion of Landlord, certain of these expenses may be equitably apportioned
among two or more buildings in the Complex.

          (ii)  The term "Operating Expenses" shall not include any of the
following, except to the extent that such costs and expenses are specifically
included in Operating Expenses as described in Section 2.2(b)(i) above: capital
expenditures and depreciation of the Building; painting and decorating of tenant
space; interest and amortization of mortgages; ground rent; compensation paid to
officers or executives of Landlord; taxes as measured by the net income of
Landlord from the operation of the Building; insurance reimbursements of
Operating Expenses to Landlord; Real Estate Taxes; brokerage commissions; and
marketing expenses.

          (iii) If the Building's occupancy level is seventy percent (70%) or
less for six (6) months or more during any Fiscal Year other than the Base Year,
or if all land and improvements upon which Operating Expenses are calculated or
may be calculated pursuant to Section 2.2(b)(i) above were not fully complete
and operational, or if any tenant is separately paying for services or utilities
furnished to its premises or is provided with fewer services than customarily
provided for tenants of general office space in the Building, then Operating
Expenses paid during such Fiscal Year or portion thereof (other than the Base
Year) may be adjusted, at Landlord's sole option, to include all additional
expenses, as estimated by Landlord applying standard accounting procedures, so
that Tenant's share of Operating Expenses is the amount which Tenant would bear
if the Building were fully occupied by tenants and all land and improvements
upon which Operating Expenses are calculated or may be calculated pursuant to
Section 2.2(b)(i) above were fully complete and operational during the entire
such Fiscal Year using services and utilities customarily provided for general
office use. For example, if the occupancy rate for the Building during at least
six (6) months of a Fiscal Year is seventy percent (70%), and if the janitorial
contractor charges $1.00 per square foot of occupied rentable area per year, and
if the Building contains 100,000 square feet of rentable area, and if Landlord
estimates that the Operating Expenses that would have been paid if the Building
had been one hundred percent (100%) occupied by tenants, using such customary
janitorial services during such year, would have been $100,000, then Tenant
would pay as Additional Rent pursuant to Section 1.5(b) its pro rata share of
the amount by which $100,000 exceeds the Operating Expenses which were paid
during the Base Year.

  2.3 ADDITIONAL RENT ESTIMATES AND ADJUSTMENTS.

      (a) Initial Additional Rent Adjustments. Landlord at its option may submit
to Tenant prior to the date set forth in Section 1.5 a statement of Landlord's
reasonable estimate of the increases described in Sections 2.2(a) and (b)
above, together with the amount of Tenant's Additional Rent which is estimated
to result from such increases, in which event Tenant shall pay such estimated
Additional Rent to Landlord in equal monthly installments beginning on the date
set forth in Section 1.5, on the dates and in the manner required for the
payment of Tenant's monthly installments of Base Annual Rent. In the
alternative, as soon as practicable after the end of the calendar year in which
Tenant's obligation to pay Additional Rent pursuant to Sections 2.2(a) and (b)
commences, Landlord may submit a lump sum statement to Tenant of the actual
increases in Real Estate Taxes and/or Operating Expenses, if any, which were
paid during the Fiscal Year which ended during such calendar year over the Real
Estate Taxes and Operating Expenses which were paid during the Base Year, all
as prorated based upon that portion of the Fiscal Year falling within the
initial partial year of the Lease Term, and Tenant shall pay its pro rata share
as Additional Rent on the date and in the manner required for the next monthly
installment of Base Annual Rent due after submission of Landlord's statement.

      (b) Annual Budget. Subsequent to the Calendar Year in which Tenant's
obligation to pay each component of Additional Rent pursuant to Section 2.2
commences, Tenant shall thereafter pay each such component of Additional Rent in
twelve equal monthly installments based upon Landlord's estimates. In order to
provide for the current monthly payment of each component of Additional Rent
described herein, Landlord shall submit to Tenant a statement of Landlord's
reasonable estimate of the increases described in Section 2.2 above, together
with the amount of Tenant's Additional Rent which is estimated to result from
such increases. Tenant agrees to pay each such estimated component of Additional
Rent to Landlord in twelve equal installments beginning on January 1, on the
dates and in the manner required for the payment of Tenant's monthly
installments of Base Annual Rent.

      (c) Additional Rent Reconciliations. After the end of each Calendar Year,
Landlord will submit to Tenant an audited financial statement of the actual
increases in Real Estate Taxes and Operating Expenses paid during the Fiscal
Year which ended during such Calendar Year over the Real Estate Taxes and
Operating Expenses which were paid during the Base Year, respectively. Such
statement shall also indicate the amount of Tenant's excess payment or
underpayment of Additional Rent based on Landlord's estimate described in
Sections 2.3(a) and 2.3(b). If Additional Rent paid by Tenant during the
preceding Calendar Year shall be in excess of, or less than, the aggregate of
its share of the actual increase in Real Estate Taxes and Operating Expenses,
Landlord and Tenant agree to make the appropriate adjustment following the
submission of Landlord's statement. Tenant shall either pay any Additional Rent
due with the installment of Base Annual Rent due for the month following
submission of Landlord's statement, or pay any Additional Rent due within thirty
(30) days if the Lease Term has expired or has otherwise been terminated. Tenant
shall deduct its excess payment, if any, from the installment of Base Annual
Rent due for the month following submission of Landlord's statement, or
following the expiration or earlier termination of the Lease Term, Tenant shall
be reimbursed for any excess payments made, less any amounts then due Landlord
under this Lease, upon demand.

<PAGE>   56


              (d) Verification of Additional Rent. Unless Tenant asserts
specific errors within thirty (30) days after Landlord has submitted the audited
financial statement for a Fiscal Year to Tenant, Tenant shall have no right to
contest the amount of Tenant's pro rata share of Real Estate Taxes and/or
Operating Expenses or the statement submitted by Landlord. No such assertion of
error by Tenant shall extend the time for payments as set forth in Sections 2.2
and 2.3 above. If Tenant has given a timely assertion of error and if it shall
be determined by Landlord there is an error in Landlord's statement, Tenant
shall be entitled to a credit for any overpayment, which shall be applied to any
sums then due Landlord under this Lease and then to the next installment(s) of
Additional Rent until fully credited for the overpayment, or refunded if Tenant
has vacated the Demised Premises, or Tenant shall be billed for any underpayment
and shall remit any amount owing to Landlord within ten (10) business days of
Tenant's receipt of such statement.

              (e) Fiscal Year. Landlord shall have the right to change its
Fiscal Year from time to time. If Landlord changes its Fiscal Year during the
Lease Term, thereby creating a Fiscal Year with fewer than twelve (12) months
(hereinafter "short year"), the Real Estate Taxes and Operating Expenses for the
short year shall be determined on an annualized basis by taking the monthly
average of the actual Real Estate Taxes and Operating Expenses, respectively,
and multiplying each by twelve. The amounts determined by this method shall be
used in determining the increases described in Sections 2.2(a) and 2.2(b) for
the short year.

       2.4    RENT ADJUSTMENT LIMIT. Notwithstanding any deductions from or
adjustments to Base Annual Rent and Additional Rent as provided for above, in no
event shall the total monthly installment of Base Annual Rent and Additional
Rent to be paid by Tenant in any month during the Lease Term or any extension
thereof be less than the monthly installment of Base Annual Rent stipulated in
Section 1.3, except as required as the result of the Landlord's application of a
credit due to Tenant pursuant to Section 2.3(c).

       2.5    SURVIVAL OF RENT OBLIGATION. The obligation of Tenant with respect
to payment of Base Annual Rent, as defined in Section 2.1, and Additional Rent
as defined in Sections 2.2 and 2.10, together with all other sums due hereunder,
accrued and unpaid during the Lease Term, shall survive the expiration or
earlier termination of this Lease.

       2.6    PRO RATA SHARE. Tenant's "pro rata share" stipulated in Sections
1.5(a) and 1.5(b) represent the ratio that the total rentable area of the
Demised Premises bears to the total rentable area of the Building. In the event
of any dispute as to the Tenant's "pro rata share", certification of the "pro
rata share" by Landlord's architect shall be binding on both Landlord and
Tenant.

       2.7    PRORATED RENT. Any Base Annual Rent or Additional Rent payable
pursuant to Sections 2.1 and 2.2 for one or more full calendar months in a
partial Fiscal Year at the beginning or end of the Lease Term shall be prorated
based upon the number of months in the Fiscal Year. Any Base Annual Rent or
Additional Rent payable pursuant to Sections 2.1 and 2.2 for a portion of a
calendar month shall be prorated based upon the number of days in the applicable
calendar month.

       2.8    APPLICATION OF RENT. No payment by Tenant or receipt by Landlord
of lesser amounts of Base Annual Rent or Additional Rent than those required by
this Lease shall be deemed to be other than on account of the earliest unpaid
stipulated Base Annual Rent or Additional Rent. No endorsement or statement on
any check or any letter accompanying any check or payment as Base Annual Rent or
Additional Rent shall be deemed an accord and satisfaction, and Landlord may
accept such check or payment without prejudice to Landlord's right to recover
the balance of such Base Annual Rent and Additional Rent or pursue any other
remedy provided in this Lease. Any credit due to Tenant hereunder by reason of
overpayment of Base Annual Rent or Additional Rent shall first be applied to any
Base Annual Rent, Additional Rent or other sums owed to Landlord by Tenant as
set forth elsewhere in this Lease or if Tenant shall be in default when said
credit shall be owed.

       2.9    LATE PAYMENT FEE AND INTEREST CHARGE. In the event any installment
of Base Annual Rent or Additional Rent due hereunder is not paid within ten (10)
calendar days after it is due, then Tenant shall also pay to Landlord as
Additional Rent (a) a late payment fee equal to five percent (5%) of the payment
as liquidated damages for the additional administrative costs incurred by
Landlord as a result of such late payments, plus (b) an interest charge
calculated at the rate of eighteen percent (18%) per annum on the delinquent
payment from the date due until paid.

       2.10   OTHER TENANT COSTS AND EXPENSES. All costs and expenses which
Tenant assumes or agrees to pay to Landlord pursuant to this Lease, including
without limitation costs of construction and alterations, shall be deemed
Additional Rent, whether or not the same is specifically designated herein as
Additional Rent, and, in the event of nonpayment thereof, Landlord shall have
all the rights and remedies herein provided for the nonpayment of Base Annual
Rent and Additional Rent payable pursuant to Sections 2.1 and 2.2, including
assessment of late payment fees and interest charges.

3.            CONSTRUCTION OF PREMISES AND OCCUPANCY

       3.1    TENANT PLANS, CONSTRUCTION AND RENT LIABILITY. Exhibit F attached
to this Lease, describes the obligations of Landlord and Tenant, and the
respective time periods for performance thereof, for the preparation and
approval of construction plans, cost estimates, working drawings and completion
of improvements and fixturing for occupancy. The improvements to be constructed
by Landlord in the Demised Premises are hereinafter referred to as the
"Construction Improvements". Said time periods shall apply irrespective of
whether Tenant uses the architect, engineer and/or general contractor selected
by Landlord, or firms of Tenant's own selection. The Tenant shall deliver to
Landlord, by the date specified on Exhibit F, a preliminary plan approved in
writing by the Tenant showing Tenant's partition, electrical and telephone
requirements, planned occupancy numbers and distribution within the Demised
Premises, and all other requirements set forth in the Tenant Plans Guidelines,
attached hereto and made a part hereof as Exhibit E, or otherwise deemed
necessary by the Landlord for the preparation of the working drawings and cost
estimate.

              (a) Preparation of Tenant Plans.

                  (i) If Tenant uses architects and engineers selected by
Landlord, Landlord shall pay for preparation of the first preliminary plan (and
one revision) specified on Exhibit F, and the first set of working drawings (and
one set of revisions) for building standard design features (as defined in the
Outline Specifications, if any, attached hereto and made a part hereof as
Exhibit B, and applicable to first generation space only) or for design features
to be built at Landlord's expense (applicable to space other than first
generation space); all subsequent revisions of preliminary plans and working
drawings, plus the cost of all design work related to above building standard
design features and for design features not to be built at Landlord's expense,
as applicable, shall be at Tenant's expense.


                                       6

<PAGE>   57



                  (ii) If Tenant's architect or engineer prepares the
preliminary plan, the preliminary plan and all revisions thereto shall be at
Tenant's expense. Landlord shall pay for one set of working drawings for
building standard design features (applicable to first-generation space) or for
design features to be built at Landlord's expense (applicable to space other
than first-generation space) and one cost estimate. All design work related to
above building standard design features and to design features not to be built
at Landlord's expense and all subsequent revisions to drawings and estimates
shall be at Tenant's expense. Landlord shall have the right to approve any
architect and/or engineer selected by Tenant, which approval shall not be
unreasonably withheld, and each of Tenant's architects and engineers shall be
licensed in the jurisdiction in which the Demised Premises are located and shall
maintain (and provide Landlord with evidence of the existence of) professional
liability insurance adequate in Landlord's reasonable judgment.

                  (iii) Tenant's preliminary plan, whether prepared by an
architect or engineer selected by Landlord or by Tenant's architect or engineer,
shall provide sufficient information to permit Landlord to have working drawings
and cost estimate prepared. Tenant's preliminary plan shall be certified by the
architect or engineer preparing same to be in compliance with applicable
building and fire codes, and with The Americans with Disabilities Act and all
amendments, modifications, extensions, replacements, regulations, orders and
directives in connection therewith (the "ADA"). If the Demised Premises as
reflected on Tenant's plans are not in compliance with applicable building and
fire codes, or do not comply with all requirements of the ADA, then Tenant's
plans shall not be, nor shall they be deemed to be, acceptable to Landlord.
Landlord's approval of Tenant's plans or work does not constitute certification
by Landlord that said plans or work meet the applicable requirements of any
building or fire codes, laws or regulations, or the ADA, nor shall it impose any
liability whatsoever upon Landlord. If Tenant's preliminary plans are acceptable
to Landlord, Landlord shall have working drawings prepared within the time
period set forth on Exhibit F, and when the working drawings are completed by
the architect and engineer, the Tenant shall approve in writing both the working
drawings and Landlord's final cost estimate within the number of working days
stipulated on Exhibit F. Tenant's failure to approve or disapprove any estimates
or plans within the time periods set forth on Exhibit F shall be deemed to
constitute approval for purposes of this Section.

              (b) Extension of Construction Timetable. Nothing contained in this
Section 3.1, nor any delay in completing the Demised Premises, shall in any
manner affect the Commencement Date set forth in Section 1.2 or Tenant's
liability for payment of Base Annual Rent and Additional Rent from such
Commencement Date, except as follows. If Landlord requires longer than the
number of working days stipulated on Exhibit F to prepare working drawings and
prepare the cost estimate following receipt of Tenant's approved preliminary
plan, or if Landlord requires longer than the number of working days stipulated
on Exhibit F to substantially complete Construction Improvements in the Demised
Premises after the final working drawings and cost estimate have been approved
by the Tenant in writing, then the Commencement Date shall be postponed by one
day for each extra day Landlord requires for the foregoing preparation of
working drawings and cost estimate and/or substantial completion of Construction
Improvements, as the case may be, which postponement shall be Tenant's sole and
exclusive remedy. In the event Tenant delays approval of either the preliminary
plan, the working drawings and/or the final cost estimate or makes changes in
the work after approval of working drawings and the final cost estimate, or
Tenant's contractors interfere with Landlord's work, thereby delaying
substantial completion and Landlord's tender of possession of the Demised
Premises to Tenant, Tenant shall nevertheless remain liable for the payment of
Base Annual Rent and Additional Rent from the Commencement Date specified in
Section 1.2. Time is of the essence as to the Tenant's performance within the
time periods specified for approval of plans and cost estimates set forth on
Exhibit F pursuant to this Section 3.1.

              (c) Substantial Completion. For the purposes of this Section 3.1,
"substantial completion" of the Construction Improvements shall mean when all
work to be performed by Landlord pursuant to the approved working drawings and
final cost estimate has been completed, except for minor items of work and minor
adjustments of equipment and fixtures that can be completed after occupancy of
the Demised Premises without causing material interference with Tenant's
reasonable use of the Demised Premises (i.e., "punch-list" items) in accordance
with the "use of the premises" as defined in Section 1.8. In the event Tenant's
plans specify any Construction Improvements that are not building standard, or
are not immediately available in the metropolitan Washington, D.C., area within
the time period for construction set forth on Exhibit F, the delivery and
installation of which precludes Landlord from substantially completing the
Construction Improvements in the Demised Premises by the Commencement Date
specified in Section 1.2, Tenant shall nevertheless remain liable for the
payment of Base Annual Rent and Additional Rent from such Commencement Date.

       3.2    POSSESSION. If Landlord shall be unable to tender possession of
the Demised Premises on the Commencement Date set forth in Section 1.2 by reason
of: (a) the fact that the Demised Premises are located in a building being
constructed and which has not been sufficiently completed to make the Demised
Premises ready for occupancy; (b) the holding over or retention of possession of
any tenant or occupant; (c) the Construction Improvements have not been
substantially completed due to delays by Landlord; or (d) for any other reason
beyond the control of Landlord, Landlord shall not be subject to any liability
for the failure to tender possession on said date. Under such circumstances the
Base Annual Rent and Additional Rent reserved and covenanted to be paid herein
shall not commence until possession of the Demised Premises is tendered to
Tenant. No such failure to tender possession on the Commencement Date set forth
in Section 1.2 shall in any other respect affect the validity of this Lease or
the obligations of Tenant hereunder, nor shall same be construed to extend the
termination date of this Lease set forth in Section 1.2. In the event the actual
Commencement Date does not occur within one (1) year of the date this Lease is
fully executed and delivered by Landlord and Tenant, then Landlord, without
further liability to Tenant, shall have the right to terminate this Lease upon
thirty (30) days prior written notice to Tenant. If permission is given to
Tenant to enter into possession of the Demised Premises prior to the date
specified as the Commencement Date, Tenant covenants and agrees that such
occupancy shall be deemed to be subject to all of the terms, covenants,
conditions and provisions of this Lease, and that Tenant shall be responsible
for payment of Base Annual Rent, in advance, at the rate of 1/30th of the base
monthly rent set forth in Section 1.3 for each day of such occupancy prior to
the Commencement Date, and Additional Rent set forth in Section 1.5 shall begin
to accrue on such date of possession.

       3.3    PERMITS. Tenant shall be responsible for obtaining at its sole
cost and expense the construction and occupancy permits for the Demised
Premises. Tenant shall be responsible for obtaining any other permits or
licenses necessary for its lawful occupancy of the Demised Premises. Tenant
shall provide Landlord with a copy of all such permits and licenses.

       3.4    DEMISED PREMISES. Landlord shall have the right to change the
location and configuration of the Demised Premises at any time, subject to the
following terms and conditions: (a) subsequent to the Commencement Date,
Landlord shall provide Tenant not less than thirty (30) days advance written
notice of the date Tenant must vacate the Demised Premises; (b) Landlord shall
provide Tenant with substitute space of similar nature and size elsewhere in the
Building or in the Complex (the "Substitute Premises"); and (c) Landlord shall
at Landlord's expense remove Tenant's Property from the Demised Premises and
reinstall them in the Substitute Premises, and redecorate the Substitute
Premises in a manner substantially similar to the manner in which the Demised
Premises were decorated. Landlord shall use reasonable efforts to minimize the
disruption to Tenant's business, but in no event shall Landlord be

                                        7


<PAGE>   58
liable for any loss of business or other damages to or expenses of Tenant,
except for any physical damage to Tenant's Property incurred during the move.
Within ten (10) days after Landlord submits an amendment of this Lease or a
replacement lease indicating the location and configuration of the Substitute
Premises, Tenant shall execute such amendment or lease, as applicable, and
deliver it to Landlord, failing which Tenant hereby irrevocably appoints
Landlord as its special attorney-in-fact to execute such amendment or lease, as
applicable, the foregoing power of attorney being deemed to be coupled with an
interest.

4.     SUBLETTING AND ASSIGNMENT

       4.1 CONSENT. Without the prior written consent of Landlord, not to be
unreasonably withheld or delayed in accordance with Section 4.5, Tenant will not
sublet the Demised Premises or any part thereof or transfer possession or
occupancy thereof to any person, firm or entity, or transfer or assign this
Lease, and no subletting or assignment hereof shall be effected by operation of
law or in any other manner, such as the transfer of all or substantially all of
Tenant's assets or voting control of Tenant's stock, partnership interest or
other equity, without such prior written consent of Landlord. If Tenant is a
partnership, then any sale, conveyance, or other transfer of, or the grant of a
security interest in, any partnership interest, or any dissolution of Tenant, or
any act which will result in a potential future change in control, or a
withdrawal or change, whether voluntary, involuntary or by operation of law, of
a partner or partners owning a controlling interest in Tenant, shall be deemed a
voluntary assignment of this Lease. If Tenant is a corporation, then any sale,
conveyance, or other transfer of, or grant of a security interest in any
controlling shares of stock, dissolution, merger, consolidation or other
reorganization of Tenant, or any sale or transfer of a controlling interest of
its capital stock, or any act which will result in a potential future change in
control, or a withdrawal or change, whether voluntary, involuntary or by
operation of law, of a shareholder or shareholders owning a controlling interest
in Tenant, shall be deemed a voluntary assignment of this Lease. All permitted
sublettings and assignments of the Demised Premises and this Lease shall be
subject to the provisions of this Lease, including but not limited to Section
4.3. No assignment shall be made except for the entire Demised Premises and
Tenant further agrees that any permitted assignment of this Lease or subletting
of the Demised Premises may be conditioned upon payment by Tenant of
consideration and the delivery of such additional guarantees, collateral and/or
other security as determined by Landlord. Any subletting or assignment consented
to by Landlord, to be effective, shall be evidenced in writing in a form
acceptable to Landlord. Consent by Landlord to any assignment or subletting by
Tenant shall not operate as a waiver of the necessity for obtaining Landlord's
consent in writing to any subsequent assignment or subletting. The collection or
acceptance of rent from any such assignee, subtenant or other occupant shall not
constitute a waiver of or release of Tenant from any covenant or obligation
contained in this Lease, nor shall such acceptance of rent be deemed to create
any right to the Demised Premises in such assignee, subtenant or other occupant,
nor any legal or other relationship between the Landlord and any such assignee,
subtenant or other occupant. Landlord's acceptance of any name for listing on
the Building directory shall not be deemed, nor will it substitute for,
Landlord's consent as required by this Lease, to each sublease, assignment and
any other occupancy of the Demised Premises. In the event that Tenant defaults
under this Lease in the payment of Base Annual Rent or Additional Rent, Tenant
hereby assigns to Landlord the rent and other sums due from any subtenant,
assignee or other occupant and hereby authorizes each such subtenant, assignee
and other occupant to pay said rent and other sums directly to Landlord upon
demand. Any transfer of this Lease or the Demised Premises, or any transfer of
any interest in Tenant restricted pursuant to this Section 4.1, without the
prior written consent of Landlord pursuant to this Section 4.1 shall be void. By
taking a transfer of this Lease by assignment, transfer of interest in Tenant,
or by any other manner described in this Section 4.1, or otherwise with
Landlord's consent to the transfer, the transferee shall be bound by all
provisions of this Lease, which shall be binding upon the transferee as if the
transferee had signed this Lease in lieu of the original Tenant named herein.

       4.2 RECAPTURE OF PREMISES. In the event Tenant desires to sublet the
Demised Premises or assign this Lease or effect the transfer of any interest in
this Lease or in Tenant restricted pursuant to Section 4.1, Tenant shall give to
Landlord written notice of Tenant's intended subtenant, assignee or transferee
in order to secure Landlord's written consent in accordance with Section 4.1.
Within ninety (90) days of receipt of said notice, Landlord shall have the
right, at its option: (i) to terminate this Lease by giving Tenant not less than
thirty (30) days notice if Tenant's notice states the Tenant's desire to assign
this Lease or sublet more than fifty percent (50%) of the Demised Premises or
effect a restricted transfer of an interest in this Lease or in Tenant; or (ii)
if Tenant's notice states the Tenant's desire to sublet a portion of the Demised
Premises, to terminate this Lease and simultaneously to enter into a new lease
with Tenant for that portion of the Demised Premises Tenant may desire to retain
upon the same terms, covenants and conditions as then set forth in this Lease,
prorated based upon the space retained by Tenant. If Landlord exercises its
right to terminate this Lease pursuant to clauses (i) or (ii) above, Tenant
agrees that Landlord shall have access to all or any portion of the Demised
Premises sixty (60) days prior to the effective termination date for remodeling
or redecorating purposes. Tenant shall promptly execute such lease amendments
and other documents as Landlord may require to effectuate the terms and intent
of this Section 4.2.

       4.3 EXCESS RENT AND OTHER CONSIDERATION. Any rent and other consideration
accruing to Tenant as the result of any sublease or any assignment of this
Lease, which is in excess of the pro rata share of Base Annual Rent and
Additional Rent then being paid by Tenant for all or a portion of the Demised
Premises being sublet or assigned, shall be paid by Tenant to Landlord monthly
as Additional Rent. Any consideration accruing to Tenant as the result of any
transfer of interest in Tenant restricted pursuant to Section 4.1, which is paid
or deemed paid in regard to the value of this Lease and which is in excess of
the pro rata share of the Base Annual Rent and Additional Rent which would have
been paid by Tenant during the Lease Term for such space, shall be paid by
Tenant to Landlord promptly as Additional Rent.

       4.4 TENANT LIABILITY. In the event of any subletting of the Demised
Premises or assignment of this Lease by Tenant or transfer of an interest in
this Lease or in Tenant, Tenant shall remain liable to Landlord for payment of
the Base Annual Rent and Additional Rent stipulated herein and all other
covenants and conditions contained herein. No subletting of the Demised Premises
or assignment of this Lease or transfer of an interest in this Lease or in
Tenant shall operate to release, discharge or otherwise affect the liability of
any guarantors, co-signers or other parties liable to Landlord pursuant to the
terms of any guaranty or otherwise for the obligations of Tenant under this
Lease.

       4.5 REASONABLE STANDARDS OF CONSENT. Tenant acknowledges that Landlord,
in considering whether to grant or withhold consent required of Landlord
pursuant to this Section 4, shall be entitled to apply any or all of the
following criteria:

              (a) The financial strength of proposed
subtenant/assignee/transferee must be acceptable to Landlord in Landlord's
reasonable discretion based on adequate current and historical financial
information given by Tenant. Landlord shall be entitled to receive, and Tenant
shall deliver or cause others to deliver, such guarantees, collateral and other
security as Landlord shall request in conjunction with any prospective sublease,
assignment or other transfer. Failure to provide such financial information,
guarantees, collateral and other security shall be grounds for Landlord to
withhold or deny consent;

                                        8

<PAGE>   59



              (b) The proposed subtenant/assignee/transferee must have a good
reputation in the business community and must be credit-worthy;

              (c) Use of the Demised Premises by the proposed
subtenant/assignee/transferee must be identical to the use permitted by this
Lease;

              (d) Use of the Demised Premises by the proposed
subtenant/assignee/transferee shall not violate or create any potential
violation of any laws and must be in keeping with the character of the Building
and the Complex;

              (e) Use of the Demised Premises by the proposed
subtenant/assignee/transferee shall not violate, or cause Landlord to violate,
any other leases, agreements or mortgages affecting (i) the Demised Premises,
the Building, the Complex or the land related to such improvements, or (ii) the
Landlord, Landlord's Agent or other tenants, whether such leases, agreements or
mortgages were entered into prior or subsequent to this Lease;

              (f) The proposed use shall be compatible with all other uses
within the Building or Complex and the proposed use or user shall not cause a
diminution in the reputation of the Building, the Complex, Landlord, Landlord's
Agent or other tenants;

              (g) The proposed subtenant/assignee/transferee shall have no right
to further sublet the subleased premises, nor to further assign this Lease, nor
to further transfer any interest in such proposed subtenant/assignee/transferee;

              (h) In the event Tenant is in default, consent may be withheld
irrespective of whether these other criteria are met by the proposed
subtenant/assignee/transferee.

       4.6 OTHER TRANSFERS. Notwithstanding anything herein to the contrary,
Tenant shall not pledge, assign, transfer, encumber or otherwise convey its
interest in the Demised Premises conditionally or as security for any
obligations of Tenant to any third party, or otherwise. Any such transfer in
violation of this provision shall be void.

       4.7 RIGHTS ON DEFAULT. In the event Tenant defaults under this Lease, in
addition to the rights and remedies of Landlord outlined in Section 12,
Landlord, at its option, may elect to recognize any sublease between Tenant and
any subtenant, or any agreement by which Tenant has granted any leasehold estate
or interest in the Demised Premises, as a direct lease or agreement between
Landlord and such subtenant or other grantee, upon written notice to Tenant and
such subtenant or other grantee, without releasing or affecting the liability of
Tenant to Landlord under this Lease, and Tenant shall be deemed to have assigned
its interest in such sublease or other agreement to Landlord (without the need
for executing any further documentation evidencing same) and such subtenant or
other grantee shall attorn to and recognize the rights of Landlord under such
sublease or other agreement, as the case may be. Notwithstanding Tenant's
consent or acquiescence in the termination of this Lease and/or Tenant's
voluntary surrender of the Demised Premises (or any portion thereof), Landlord
may consider any sublease or other agreement transferring a leasehold estate or
interest in the Demised Premises, and/or any right to use or possess the Demised
Premises (or any portion thereof) by any subtenant or other grantee, terminated
as of the date Landlord terminates this Lease and/or Tenant's right to
possession of the Demised Premises, it being the intention of the parties that
any leasehold estate or other interest in the Demised Premises shall be subject
to the terms and conditions of this Lease, including all rights and remedies of
Landlord outlined herein, notwithstanding anything to the contrary contained in
such sublease or other agreement.

5.     SERVICES AND UTILITIES

       5.1 BUILDING STANDARD SERVICES AND UTILITIES. Subject to the limitations
set forth in Section 5.3 below, Landlord shall furnish sufficient electric
current for lighting and office equipment such as typewriters, calculators,
small copiers, desktop personal computers and word processors and similar items.
Landlord shall also furnish water for lavatory and drinking purposes, lavatory
supplies, fluorescent tube replacements, automatically operated elevator service
and nightly cleaning service in accordance with Landlord's prevailing practices
(as set forth in Exhibit D attached hereto), as they may be modified from time
to time, except that Landlord shall not be responsible for cleaning Tenant's
kitchens, private bathrooms, rugs, carpeting (except vacuuming) and drapes.
Landlord shall have no liability for and expressly disclaims any responsibility
for the engineering, design, installation, provision of or maintenance of
Tenant's telecommunications and data transmission systems and the inside wire
associated therewith. Landlord further agrees to furnish heating and cooling
during the appropriate seasons of the year, between the hours and on the days
set forth in Section 1.7 (exclusive of legal public holidays as defined in
section 6103(a) and (c) of Title 5 of the United States Code, as it may
hereafter be amended, with holidays falling on Saturday observed on the
preceding Friday and holidays falling on Sunday observed on the following
Monday). All of the aforesaid services shall be provided without cost to Tenant
except as such expenses may be included in calculating Additional Rent pursuant
to the provisions of Sections 2.2 and 2.3. Landlord shall not be liable for
failure to furnish, or for suspension or delay in furnishing, any of such
services if such failure, suspension or delay is caused by breakdown,
maintenance or repair work, strike, riot, civil commotion, governmental
regulations, emergency periods due to weather or any other cause or reason
whatever beyond the reasonable control of Landlord. Failure, suspension, delay
or interruption of services shall not result in any abatement of Base Annual
Rent or Additional Rent, be deemed an eviction or breach of this Lease
(including any express or implied covenant of quiet enjoyment), or relieve
Tenant of performance of Tenant's obligations under this Lease.

       5.2 OVERTIME SERVICES. Should Tenant require heating and cooling services
beyond the hours and/or days stipulated in Section 1.7, upon receipt of at least
48 hours prior written notice from Tenant, Landlord will furnish such additional
service at the then-prevailing hourly rates for both utility services and
personnel as established by Landlord from time to time; provided, further, that
there will be a minimum charge of four (4) hours each time overtime services are
required.

       5.3 EXCESSIVE USAGE.

              (a) Equipment Restrictions. Tenant will not install or operate in
the Demised Premises any heavy duty electrical equipment or machinery or any
other equipment which consumes excess gas (where applicable), excess water,
excess sewer services or excess electricity as defined in Section 5.3(b) below,
without first obtaining prior written consent of Landlord. Landlord may, among
other things, require as a condition to its consent for the installation of such
equipment or machinery that Tenant pay as Additional Rent the costs for excess
consumption of such utilities that may be occasioned by the operation of said
equipment or machinery. Landlord may make periodic inspections of the Demised
Premises at reasonable times to determine that Tenant's equipment and machinery
comply with the provisions of this Section and Section 5.4.

                                        9
<PAGE>   60
              (b) Excess Electrical Usage. The consumption of electricity,
including lighting, in excess of five (5) watts per square foot for any portion
of the Demised Premises shall be deemed excessive. Additionally, any individual
piece of electrically operated machinery or equipment having a name plate rating
in excess of two (2) kilowatts shall also be deemed as requiring excess electric
current.

              (c) Additional Utility Costs. Landlord shall have the right to
either require that one or more separate meters be installed to record the
consumption or use of electricity or other utilities, or cause a reputable
independent engineer to survey and determine the quantity of such utilities
consumed by such excessive use. The cost of any such survey and meters and of
installation, maintenance and repair thereof shall be paid for by Tenant.
Tenant agrees to pay Landlord (or the utility company, if direct service is
provided by the utility company), promptly upon demand therefor, for all such
consumption and demand as shown by said meters, or a flat monthly charge
determined by the survey, as applicable, at the rates charged for such service
by the local public utility company. If Tenant's cost of such utilities based
on meter readings is to be paid to Landlord, Tenant shall pay a service charge
related thereto in an amount Landlord shall reasonably determine.

       5.4 EXCESSIVE HEAT GENERATION. Landlord shall not be liable for its
failure to maintain comfortable atmospheric conditions in all or any portion of
the Demised Premises due to heat generated by over-occupancy of the Demised
Premises or by any equipment, machinery or additional lighting installed by
Tenant (with or without Landlord's consent) that exceeds design capabilities for
the Building. Over-occupancy shall mean any occupancy of the Demised Premises in
excess of the planned occupancy disclosed by Tenant to Landlord pursuant to
Section 3.1. If Tenant desires additional cooling to offset excessive heat
generated by such over-occupancy, equipment, machinery or additional lighting,
Tenant shall pay for auxiliary cooling equipment and the operating, maintenance,
repair and replacement costs of such equipment, including without limitation
electricity, gas, oil and water. If Tenant does not desire such auxiliary
cooling equipment, Tenant shall pay for excess electrical consumption by the
existing cooling system.

       5.5 BUILDING SECURITY. Any security system or other security measures
(collectively, the "Security System") that Landlord may undertake for protection
of the Demised Premises, the Building and/or Complex (including any parking
garages or areas) are for the protection of the physical structures only and
shall not be relied upon by Tenant, its agents, employees or invitees to protect
Tenant, Tenant's Property and Leasehold Improvements or Tenant's employees,

          6.4  Alterations.

              (a) Approval Required. Tenant shall not make any alterations,
installations, changes, replacements, repairs, additions or improvements in or
to (or which interfere with) the structural elements of the Building or the
Demised Premises, or the Systems (hereinafter defined), without the prior
written consent of Landlord, which consent may be granted or withheld in
Landlord's sole and absolute discretion. Tenant shall not make any
non-structural, non-System or cosmetic alterations, changes, replacements,
repairs, additions or improvements in or to the Demised Premises or any part
thereof, without the prior written consent of Landlord, which consent shall not
be unreasonably withheld. All Tenant plans and specifications shall be submitted
to Landlord for prior approval. All Tenant engineering plans and specifications
shall be prepared at Tenant's expense by Landlord's designated engineer.
Landlord may, among other things, condition its consent upon Tenant's agreement
that any construction up-gradings required by any governmental authority as a
result of Tenant's work, either in the Demised Premises or in any other part of
the Building or Complex, will be paid for by Tenant in advance. Tenant shall not
install any equipment of any kind or nature whatsoever which will or may
necessitate any changes, replacements or additions to the water system, plumbing
system, heating system, ventilating system, air-conditioning system, supply,
return or control systems, Landlord's data system(s), or the electrical system
of the Demised Premises or the Building (collectively, the "Systems"), nor
install or use any air-conditioning unit, engine, boiler, generator, machinery,
heating unit, stove, water cooler, ventilator, radiator or any other similar
apparatus, nor modify or interfere with any of the Systems, without the prior
written consent of the Landlord, which consent may be granted or withheld in the
Landlord's sole and absolute discretion. Any auxiliary air-conditioning
equipment which Tenant may desire to install in the Demised Premises shall be
connected to the Building's commercial condenser water system, if available, and
Tenant shall pay to Landlord such reasonable charges as established by Landlord
from time to time for the use of the Building's commercial condenser water
system. Tenant shall not modify or interfere with the Systems without the prior
written consent of Landlord, and then only as Landlord may direct. Landlord may
condition its consent upon Tenant's payment of all costs to make such changes,
replacements or modifications. Tenant shall not design, configure, install, use
or arrange for the design, configuration, installation or use of its
telecommunications and data transmission systems or inside wire associated
therewith in any manner that interferes with the existing telecommunications
and/or data transmission systems or inside wire associated therewith of Landlord
or other tenants in the Building. Landlord's consent to any work by Tenant or
approval of Tenant's plans or specifications shall not be deemed a certification
that such work complies with applicable building codes, laws or regulations, nor
shall it impose any liability whatsoever upon Landlord.

              (b) Alteration Requirements. All of Tenant's approved work shall
be done in accordance with Landlord's Supplemental Rules and Regulations for
Contractors (as promulgated and amended by Landlord from time to time) and shall
be done by duly qualified, licensed and bonded contractors in accordance with
all applicable laws, codes, ordinances, rules and regulations, and Tenant shall
obtain (or give) at its cost any required permits, licenses, registrations,
notices, or inspections for performance of its work. Prior to the commencement
of such work Tenant must either deposit with Landlord evidence of the existence
of a bond deemed sufficient by Landlord against construction liens, or obtain an
executed waiver of lien from each contractor or vendor that will perform or
furnish to Tenant work, labor, services or materials for any alterations,
installations, replacements, additions or improvements in or to the Demised
Premises. Notwithstanding the aforesaid, if any mechanic's or materialman's lien
shall at any time, whether before, during or after the Lease Term, be filed
against any part of the Building or other property of Landlord by reason of
work, labor, services or materials performed for or furnished to or on behalf of
Tenant, Tenant shall forthwith cause the lien to be released of record by being
discharged or bonded off to Landlord's satisfaction within five (5) days after
being notified of the filing thereof. If Tenant shall fail to cause such lien to
be released of record within said five (5) day period, then, in addition to any
other right or remedy of Landlord, Landlord may bond off or discharge the lien
by paying the amount claimed to be due. Any amount paid by Landlord, whether as
bond premium or payment of the lien amount, and all costs and expenses,
including reasonable attorneys' fees incurred by Landlord in procuring the same
and its release from the appropriate land records, shall be due from Tenant to
Landlord as Additional Rent, and shall be payable on the first day of the next
following month, or if the Lease Term has expired, upon demand.

              (c) Removal of Leasehold Improvements and Tenant's Property. All
Leasehold Improvements within the Demised Premises shall, subject to Landlord's
right to require Tenant to remove all or any portion of the Leasehold
Improvements and restore the Demised Premises to its condition as of the date
this Lease is fully executed and delivered by Landlord and Tenant, remain at the
expiration or earlier termination of the Lease Term without disturbance,
molestation or injury. Should Landlord elect that Leasehold Improvements be
removed upon the expiration or earlier termination of the Lease Term, and/or
should Tenant fail to remove all or any portion of Tenant's Property in
accordance with the provisions of this Lease, Tenant hereby agrees that Landlord
shall have the right to cause all or any portion of the Leasehold Improvements
and/or Tenant's Property to be removed at Tenant's sole cost and expense. Tenant
hereby agrees to reimburse Landlord for the cost of such removal together with
the cost of repairing any damage resulting therefrom, and the cost of restoring
the Demised Premises to its condition as of the date this Lease is fully
executed and delivered by Landlord and Tenant. Approximately sixty (60) days
prior to Tenant's scheduled vacation of the Demised Premises, Landlord and
Tenant shall meet to review what items shall be removed and what items shall
remain as Landlord may determine. Landlord shall provide its estimate to Tenant
of the costs of such removal and the costs of any repairs to or restoration of
the Demised Premises as herein provided, and Tenant shall promptly deposit with
Landlord a sum equal to such estimated costs. In the event Tenant fails to
remove the Leasehold Improvements designated by Landlord for removal prior to
the expiration of the Lease Term and/or fails to remove Tenant's Property as
aforesaid and/or fails to make such repairs and/or restoration as aforesaid,
Landlord shall cause the removal, repair and/or restoration to be performed at
Tenant's sole expense, which expense shall not be limited by the amount of the
deposit referred to herein. Tenant shall provide for the transfer or disposal of
all items removed, failing which Landlord is hereby authorized to dispose of
same in any manner deemed appropriate, including, but not limited to, disposal
into the trash, without liability to Tenant, and at Tenant's sole cost and
expense, and Tenant shall indemnify, defend and hold harmless Landlord,
Landlord's Agent and their respective employees and agents from and against all
claims, damages, costs and expenses, including reasonable attorneys' fees,
arising from or in connection with the disposal of all or any items removed by
Landlord hereunder. In the event, for whatever reason, the parties do not meet
to review which items shall be removed and which items shall remain, and/or the
Tenant, for whatever reason, fails to deposit with the Landlord the deposit
hereinabove stated, then the Landlord is hereby authorized to proceed, as it
deems appropriate, with such removal and disposition of property, and repair
and/or restoration, without liability to Tenant, and at Tenant's sole cost and
expense.

              (d) Compliance with Laws.  In the event that during the Lease Term
either Landlord or Tenant shall be required by the order or decree of any court,
or any other governmental authority, or by law, code or ordinance (including but
not limited to the ADA), to repair, alter, remove, reconstruct, or improve any
part of the Demised Premises or of the Building, then Tenant agrees, at its sole
cost and expense, to comply with such requirements imposed on Demised Premises
or Tenant and shall perform, at its expense, or Tenant shall permit Landlord to
perform, at Tenant's expense, such repairs, alterations, removals,
reconstructions, or improvements. Within

common areas located within the Building, including external landscaping,
walkways and parking areas, and, except to the above extent, Landlord shall make

pursuant to the provisions of Sections 2.2 and 2.3; and (ii) if such expenses
are incurred by Landlord in making repairs attributable to acts or omissions of
Tenant or Tenant's employees, agents, contractors or invitees, then Tenant shall
reimburse Landlord for all such expenses within ten (10) days after Landlord
submits a bill for such costs to Tenant. Tenant hereby waives all claims for

materials, equipment, pipes, ducts, conduits, wires, and related fluids, gases,
components and mechanical equipment serving other portions, tenants and
occupants of the Building, in, through, under or above the Demised Premises that
Landlord deems desirable and shall have the right to locate, both vertically and
horizontally, utility lines, wiring, air ducts, flues, duct shafts, drains,
sprinkler mains and valves, and such other facilities within the Demised
Premises as may be deemed necessary by engineering design and/or code and/or
other legal requirements and to repair, alter, replace or remove these items.
These shall be located so as to cause minimum interference with Tenant's use of
the Demised Premises and shall, if possible, be located above Tenant's suspended
ceiling, if any, or as close to the concrete slab as possible, below the floor,
along column lines or in storage areas. Landlord shall have the right to remove
or abate any hazardous materials located in the Demised Premises and Tenant
shall fully cooperate with Landlord in this regard. Landlord's right to locate
facilities within the Demised Premises shall include facilities required by
tenants or occupants in levels above or below the Demised Premises as well as on
the same level as the Demised Premises. None of the above conduct by Landlord
shall be deemed to constitute an interference with Tenant's quiet enjoyment or
an actual or constructive eviction of Tenant. Tenant shall be entitled to no
abatement of Base Annual Rent or Additional Rent whatsoever on account of such
installation, location, construction, use, entry, removal, repair, maintenance
or other conduct as aforesaid.

          6.6  SIGNS AND PUBLICATIONS. No sign, advertisement or notice shall be

style as Landlord shall approve. Landlord shall have the right to prohibit any
signage or publication of Tenant on the Demised Premises which in Landlord's
opinion tends to impair the reputation or character of the Building, Complex,
Landlord or Landlord's Agent. Tenant shall refrain from and discontinue such
signage or publication upon receipt of written notice from Landlord, but in no
event later than one (1) day after receipt of such notice.

          6.7  EXCESSIVE FLOOR LOAD. Landlord shall have the right to prescribe

exceeding the designed floor load capacity of the floor and the Building.
Landlord may prescribe the placement and positioning of all such objects within
the Demised Premises and/or Building, and, if necessary, such objects shall be
placed upon platforms, plates or footings of such size as Landlord shall
prescribe. All damage done to the Building or the Demised Premises by installing
or removing a safe or any other article of Tenant's Property or fixtures, or due
to its being in the Demised Premises, shall be repaired at the expense of
Tenant.

for moving same. Deliveries from lobby and freight areas requiring use of hand
carts shall be restricted to freight elevators. All hand carts shall be equipped
with rubber tires and side guards. Any control exercised by Landlord hereunder
shall be deemed solely for the benefit of Landlord and the Building, and shall
not be deemed to make any of Tenant's employees, agents or contractors the agent
or servant of Landlord. Tenant shall promptly remove from the public areas in or
adjacent to said Building any of Tenant's property delivered or deposited there.

              (c) Moving Damages. Any and all damage or injury to the Demised
Premises or the Building caused by moving the property of Tenant into or out of
the Demised Premises shall be repaired at the sole cost of Tenant. In

harmless with respect to any and all damages and injuries to the Demised
Premises or the Building, and with respect to any property damage and injury to

contractual liability endorsement that refers expressly to this Lease.

          (b) Fire and Casualty Insurance. During the Lease Term, Tenant at its
cost shall maintain fire and extended coverage insurance on all special or above
building standard work (as defined in Exhibit B, if applicable), all alterations
and all other contents of the Demised Premises, including any Leasehold
Improvements and Tenant's Property, in an amount sufficient so that no
coinsurance penalty will be applied in case of loss.

          (c) Increases in Coverage. Tenant shall increase its insurance
coverage as required if in the reasonable opinion of the mortgagee on the
Building, Landlord or Landlord's insurance agent such insurance coverage at that
time is not adequate.

          (d) Policy Requirements. All insurance required under this Lease shall
be issued by insurance companies authorized to do business in the jurisdiction
where the Building is located. Such companies shall have a policyholder rating
of at least "A" and be assigned a financial size category of at least "Class X"
as rated in the most recent edition of "Best's Key Rating Guide" for insurance
companies. If at any time during the Lease Term the rating of any of Tenant's
insurance carriers is reduced below the rating required pursuant to the terms
hereof, Tenant shall promptly replace the insurance coverage(s) maintained with
such carrier with coverage(s) from a carrier whose rating complies with the
foregoing requirements. If the Best's Key Rating Guide is discontinued or
revised without substitution of a comparable rating system, Landlord shall
reasonably determine its satisfaction with the insurance company issuing
Tenant's policies. Each policy shall contain an endorsement requiring thirty
(30) days written notice from the insurance company to Landlord before
cancellation or any change decreasing coverage, scope or amount of such policy
and an endorsement naming Landlord and Landlord's Agent as additional insureds.
Each policy, or a certified copy of the policy, and a certificate showing it is
in effect, together with evidence of payment of premiums, shall be deposited
with Landlord at the commencement of the Lease Term and thereafter upon any
policy changes or substitutions, and renewal certificates and copies of renewal
policies shall be delivered to Landlord at least thirty (30) days prior to the
expiration date of any policy.

          (e) No Limitation of Liability. Notwithstanding the fact that any
liability of Tenant to Landlord may be covered by Tenant's insurance, Tenant's
liability shall in no way be limited by the amount of its insurance recovery or
the amount of insurance in force or required by any provisions of this Lease.

                                       14

<PAGE>   65


              (f) Waiver of Subrogation. Notwithstanding anything to the
contrary contained herein, Landlord and Tenant hereby mutually waive and release
their respective rights of recovery against each other for any loss of its
property (in excess of a reasonable deductible amount) capable of being insured
against by fire and extended coverage insurance or any insurance policy
providing property damage coverage, whether carried or not. Each party shall
apply to its insurer to obtain said waiver and obtain any special endorsement,
if required by its insurer to evidence compliance with the aforementioned
waiver, and shall bear the cost therefor.

              (g) Business Interruption. Landlord, Landlord's Agent and their
respective agents and employees shall have no liability or responsibility for
any loss, cost, damage or expense arising out of or due to any interruption of
business (regardless of the cause therefor), increased or additional cost of
operation of business or other costs or expenses, whether similar or dissimilar,
which are capable of being insured against under business interruption
insurance, whether or not carried by Tenant.

       8.6    INCIDENT REPORTS. Tenant shall promptly report to Landlord's Agent
all accidents and incidents occurring on or about the Demised Premises, the
Building and/or the Complex which involve or relate to the security and safety
of persons and/or property.

9.           DAMAGE

       9.1    DAMAGES CAUSED BY TENANT. Subject to the provisions of Sections
8.5(f) and 9.2, in the event of damage to the Demised Premises or other portions
of the Building caused by the acts or omissions of Tenant, its agents,
employees, invitees or visitors, the Landlord may, but shall not be obligated
to, repair such damage at the expense of Tenant, or, at Landlord's option, such
damages shall be repaired by Tenant, at Tenant's expense, with Landlord's
approval in accordance with Section 6.4. At Landlord's option, Tenant shall
either (a) pay to Landlord the estimated cost of such repairs and/or maintenance
within ten (10) days of Tenant's receipt of Landlord's estimate, or (b) upon
completion of such repairs and/or maintenance by Landlord, pay to Landlord the
actual cost of such repairs and/or maintenance (or the difference between the
actual cost and the estimated costs previously paid by Tenant) within ten (10)
days of receipt of invoice from Landlord. Landlord's recovery shall not be
limited to the diminution in the value of the Demised Premises or leasehold
notwithstanding that such repairs and maintenance may occur prior to the
expiration of the Lease Term. All such costs shall be deemed Additional Rent.
This provision shall be construed as an additional remedy granted to Landlord
and not in limitation of any other rights and remedies which Landlord has or may
have in said circumstances.

       9.2    FIRE OR CASUALTY DAMAGE. In the event of damage or destruction of
the Demised Premises or a portion thereof by fire or any other casualty not due
to the acts or omissions of Tenant, its agents, employees, invitees or visitors,
then, except as otherwise provided in Section 9.3, this Lease shall not be
terminated, but structural damage to the Demised Premises, including demising
partitions and doors, shall be promptly and fully repaired and restored as the
case may be by Landlord at its own cost and expense. Due allowance, however,
shall be given for reasonable time required for adjustment and settlement of
insurance claims, and for such other delays as may result from government
restrictions, and controls on construction, if any, and for strikes, national
emergencies and other conditions beyond the control of Landlord. Restoration by
Landlord shall not include replacement of Tenant's Property or that portion of
the Leasehold Improvements provided by Landlord as of the Commencement Date
above the building standard items as of the Commencement Date. If the items
which Landlord provides as building standard items have changed since the
Commencement Date, then, at Landlord's election, such restoration shall not
include restoration of Leasehold Improvements in excess of those provided by
Landlord as building standard as of the date of such restoration. Tenant shall,
at its expense, repair, restore and replace Tenant's Property and all elements
of the Demised Premises excluded from the scope of Landlord's duty to restore
pursuant to this Section 9.2. Tenant's restoration, replacement and repair work
shall comply with Section 6 hereof and Tenant shall maintain adequate insurance
on all such replacements, restoration and property pursuant to Section 8.5. In
the event of fire or casualty damage to the Demised Premises caused by the
fault, act or omission or neglect of Tenant, its agents, employees, invitees or
visitors, Landlord may, but shall not be obligated to, restore all or any
portion of the damage described herein (which may or may not include the Demised
Premises). It is agreed that in any of the aforesaid events, this Lease shall
continue in full force and effect.

       9.3    UNTENANTABILITY.

              (a) Restoration Requirements.

                  (i) If the condition referred to in Section 9.2 is such that
the Demised Premises are partially damaged or destroyed and provided that the
condition was not due to the acts or omissions of Tenant, its agents, employees,
invitees or visitors, then during the period that Tenant is deprived of the use
of the damaged portion of the Demised Premises, Tenant shall be required to pay
Base Annual Rent and Additional Rent covering only that part of the Demised
Premises that Tenant is able to occupy, based on the ratio between the square
foot area remaining that can be occupied and the total square foot area of the
entire Demised Premises covered by this Lease. Any unpaid or prepaid installment
of Base Annual Rent and Additional Rent for the month in which the condition
referred to in Section 9.2 occurs shall be prorated.

                  (ii) (1) If the condition referred to in Section 9.2 is such
so as to make the entire Demised Premises untenantable and provided that the
condition was not due to the acts or omissions of Tenant, its agents, employees,
invitees or visitors, then, subject to the rights set forth in Section
9.3(a)(ii)(2) below, the installment(s) of Base Annual Rent and Additional Rent
which Tenant is obligated to pay hereunder shall abate as of the date of the
occurrence until the restoration of the Demised Premises has been substantially
completed by Landlord to the extent of Landlord's obligations as described in
Section 9.2. Any unpaid or prepaid installment of Base Annual Rent and
Additional Rent for the month in which the condition referred to in Section 9.2
occurs shall be prorated.

                       (2) In the event (x) the Demised Premises are
substantially or totally destroyed by fire or other casualty so as to be
entirely untenantable, (y) a substantial portion of the Building is destroyed or
damaged to such an extent that, in the sole judgment of Landlord, the Building
cannot be operated as a functional unit or an economically viable unit, or (z)
the damage to the Demised Premises and/or the Building is due to an uninsured
risk or insurance proceeds are otherwise unavailable to cover the expenses of
restoration or repair of the damage (less any applicable deductible), then
Landlord shall have the unconditional right to cancel this Lease in its sole
discretion, in which case Base Annual Rent and Additional Rent shall be
apportioned and paid to the date of said fire or other casualty. If Landlord
elects not to cancel this Lease, then Landlord shall determine and notify Tenant
in writing, within sixty (60) days following the fire or other casualty, of the
date by which the Demised Premises can be restored by Landlord in accordance
with the provisions of Section 9.2. If the date determined by Landlord as
aforesaid for completion of restoration of the Demised Premises is more than one
hundred twenty (120) days after such fire or other casualty, then Tenant shall
have the right, to be exercised by giving written notice to Landlord within ten
(10) days following receipt of such notice from Landlord, to cancel and
terminate this Lease.



                                       15


<PAGE>   66


In the event the date by which Landlord determines it can complete restoration
of the Demised Premises as herein provided is less than 120 days following such
fire or other casualty, or Tenant fails to terminate this Lease as herein
provided following notification from Landlord that completion of restoration
will require more than 120 days, then this Lease shall remain in full force and
effect and Landlord shall commence restoration of the Demised Premises to the
extent of Landlord's obligations as described in Section 9.2. Due allowance,
however, shall be given for reasonable time required for adjustment and
settlement of insurance claims, for Landlord to reasonably be able to determine
the time necessary for completion of the restoration and for other such delays
as may result from government restrictions, and controls on construction, if
any, and for strikes, national emergencies and other conditions beyond the
control of Landlord. Any delays as a result of the foregoing shall operate to
postpone Landlord's obligation to complete restoration of the Demised Premises
by one day for each day of any such delay. Tenant shall commence any restoration
to be performed by Tenant as required in Section 9.2 and Tenant shall reoccupy
the Demised Premises when restored.

                  (iii) Except as expressly provided in this Section 9.3, no
compensation, or claim, or diminution of Base Annual Rent or Additional Rent
will be allowed or paid by Landlord, by reason of inconvenience, annoyance, or
injury to business, arising from any fire or other casualty suffered by Tenant
or the necessity of repairing or restoring the Demised Premises or any portion
of the Building.

       (b)  Casualty Near Expiration of Lease Term. In addition to any other
right of Landlord or Tenant to terminate this Lease pursuant to the provisions
of this Section 9, in the event the Demised Premises are damaged in whole or in
part by fire or other casualty during the last twelve (12) months of the Lease
Term, then Landlord or Tenant, upon ten (10) days prior written notice to the
other given within sixty (60) days of the date of the fire or casualty, may
terminate this Lease, in which case the Base Annual Rent and Additional Rent
shall be apportioned and paid to the date of said fire or other casualty;
provided, however, Tenant shall have no right to terminate this Lease hereunder
if prior to receipt of Tenant's notice Landlord has commenced to repair or
restore the Demised Premises.

10.          CONDEMNATION

       10.1   LANDLORD'S RIGHT TO AWARD. Tenant agrees that if any of the
Demised Premises or the Building shall be taken or condemned for public or
quasi-public use or purpose by any competent authority, Tenant shall have no
claim against Landlord and shall not have any claim or right to any portion of
the amount that may be awarded as damages or paid as a result of any such
condemnation. All rights of Tenant to damages therefor, if any, are hereby
assigned by Tenant to Landlord. Upon such condemnation or taking, the Lease Term
shall cease and terminate from the date of such governmental taking or
condemnation. If (a) the whole or a substantial part of the Demised Premises or
the Building is taken or condemned or if (b) less than a substantial portion of
the Building or the Demised Premises is taken or condemned and the remainder of
either in Landlord's opinion can not be operated as a functional unit or as an
economically viable unit, Landlord shall notify Tenant of the termination of
this Lease effective as of the date of such governmental taking or condemnation.
In the event of any termination of this Lease by reason of any taking or
condemnation, Tenant shall have no claim against Landlord or Landlord's Agent
for the value of any unexpired portion of the Lease Term. If less than a
substantial part of the Demised Premises or of the Building is taken or
condemned by any governmental authority for public or quasi-public use or
purpose and the remainder of both in Landlord's opinion can be operated as a
functional unit or as an economically viable unit, the rent shall be equitably
adjusted on the date when title vests in such governmental authority and the
Lease shall otherwise continue in full force and effect. For the purposes of
this Section 10, a substantial part of the Demised Premises shall be considered
to have been taken if more than fifty percent (50%) of the Demised Premises are
unusable by Tenant.

       10.2   TENANT'S RIGHT TO FILE CLAIM. Nothing in Section 10.1 shall
preclude Tenant from filing a separate claim against the condemning authority
for the value of its Leasehold Improvements not then depreciated (excluding
those Leasehold Improvements paid for by Landlord) and relocation expenses,
provided that any award to Tenant will not result in a diminution of any award
to Landlord.

11.           BANKRUPTCY

       11.1   EVENTS OF BANKRUPTCY The following shall be Events of Bankruptcy
under this Lease:

              (a) Tenant's becoming insolvent, as that term is defined in Title
11 of the United States Code, entitled Bankruptcy, 11 U.S.C. Sec. 101 et seq.
(the "Bankruptcy Code"), or under the insolvency laws of any State, District,
Commonwealth or Territory of the United States ("Insolvency Laws");

              (b) The appointment of a receiver or custodian for any or all of
Tenant's Property or assets, or the institution of a foreclosure action upon any
of Tenant's real or personal property;

              (c) The filing of a voluntary petition under the provisions of the
Bankruptcy Code or Insolvency Laws;

              (d) The filing of an involuntary petition against Tenant as the
subject debtor under the Bankruptcy Code or Insolvency Laws, which is either not
dismissed within sixty (60) days of filing, or results in the issuance of an
order for relief against the debtor, whichever is earlier; or

              (e) Tenant's making or consenting to an assignment for the benefit
of creditors or a common law composition of creditors.

       11.2   LANDLORD'S REMEDIES.

              (a) Termination of Lease. Upon occurrence of an Event of
Bankruptcy, Landlord shall have the right to terminate this Lease by giving
written notice to Tenant; provided, however, that this right to terminate shall
have no effect while a case in which Tenant is the subject debtor under the
Bankruptcy Code is pending, unless Tenant or its Trustee is unable to comply
with the provisions of Sections 11.2(d) and (e) below. At all other times this
Lease shall automatically cease and terminate, and Tenant shall be immediately
obligated to quit the Demised Premises upon the giving of notice pursuant to
this Section 11.2(a). Any other notice to quit, or notice of Landlord's
intention to re-enter is hereby expressly waived. If Landlord elects to
terminate this Lease, everything contained in this Lease on the part of Landlord
to be done and performed shall cease without prejudice, subject, however, to the
rights of Landlord to recover from Tenant all Base Annual Rent and Additional
Rent and any other sums accrued up to the time of termination or recovery of
possession by Landlord, whichever is later, and any other monetary damages
sustained by Landlord.



                                       16


<PAGE>   67
          (b) Suit for Possession. Upon termination of this Lease pursuant to
Section 11.2(a), Landlord may proceed to recover possession of the Demised
Premises under and by virtue of the provisions of the laws of any applicable
jurisdiction, or by such other proceedings, including reentry and possession, as
may be applicable, or by direct order from any Court having jurisdiction over
Tenant/Debtor, including any Bankruptcy Court.

          (c) Non-Exclusive Remedies. Without regard to any action by Landlord
as authorized by Sections 11.2(a) and (b) above, Landlord may at its discretion
exercise all the additional provisions set forth below in Section 12.

          (d) Assumption or Assignment by Trustee. In the event Tenant becomes
the subject debtor in a case pending under the Bankruptcy Code, Landlord's right
to terminate this Lease pursuant to Section 11.2(a) shall be subject to the
rights of the Trustee in Bankruptcy to assume or assign this Lease. In addition
to all other objections Landlord may raise to assumption and/or assignment, and
in addition to all other requirements of any Bankruptcy Court and the Bankruptcy
Code, the Trustee shall not have the right to assume or assign this Lease unless
the Trustee (i) has timely performed all Lease obligations of the Tenant/Debtor
arising from and after the filing of any voluntary bankruptcy petition by Tenant
or, in the case of an involuntary petition, the date of entry of the Order for
Relief, (ii) promptly cures all defaults under this Lease, (iii) promptly
compensates Landlord for monetary damages incurred as a result of such default,
and (iv) provides adequate assurance of future performance on the part of Tenant
or on the part of the assignee of Tenant or the Trustee.

          (e) Adequate Assurance of Future Performance. Landlord and Tenant
hereby agree in advance that adequate assurance of future performance, as that
term is used in Section 11.2(d) above, shall mean that all of the following
minimum criteria must be met: (i) Tenant's gross revenues in the ordinary course
of business during the thirty (30) day period immediately preceding the
initiation of the case under the Bankruptcy Code must be at least two (2) times
greater than the next installment of Base Annual Rent and Additional Rent due
under this Lease; (ii) both the average and median of Tenant's gross revenues in
the ordinary course of business during the six (6) month period immediately
preceding the initiation of the case under the Bankruptcy Code must be at least
two (2) times greater than the next six (6) installments of Base Annual Rent and
Additional Rent due under this Lease; (iii) Tenant must pay (and continue to pay
on a timely basis throughout the Lease Term) Base Annual Rent, Additional Rent
and all other sums payable by Tenant hereunder in advance and as a condition
precedent to the performance of Landlord's obligations hereunder; (iv) the
Trustee must agree that Tenant's business shall be conducted in a first class
manner, and that no liquidating sales, auctions, or other non-first class
business operations shall be conducted on or about the Demised Premises,
Building and/or Complex; (v) the Trustee must agree that the use of the Demised
Premises as stated in this Lease will remain unchanged and that no prohibited
use shall be permitted; and (vi) the Trustee must agree that the assumption or
assignment of this Lease will not violate or affect the rights of other tenants
in the Building and/or Complex.

          (f) Failure to Provide Adequate Assurance. In the event the Trustee or
Tenant is unable to (i) comply with the requirements of Section 11.2(d) above,
or (ii) meet the criteria and obligations imposed by Section 11.2(e) above,
Tenant agrees in advance that it has not met its burden to provide adequate
assurance of future performance, and this Lease may be terminated by Landlord in
accordance with Section 11.2(a) above.

     11.3 GUARANTORS. For purposes of this Section 11, any action or
adjudication by or on behalf of, or against, or with respect to the property or
affairs of, any guarantor or guarantors (if any) of this Lease, or any of them,
which, if taken by, against or with respect to Tenant, Tenant's Property or
affairs, would entitle Landlord to exercise any remedy specified herein, may be
treated, at Landlord's sole option and discretion, as though it were taken by,
against or with respect to the Tenant.

     11.4 DAMAGES. In the event of cancellation and termination of this Lease
pursuant to Section 11.2 above, Landlord shall, notwithstanding any other
provisions of this Lease to the contrary, be entitled to promptly recover
damages from Tenant determined in accordance with the provisions set forth in
Section 12.2 of this Lease as provided for in the case of default by Tenant.

12.  DEFAULTS AND REMEDIES

     12.1 DEFAULT. If any one or more of the following events occur, said event
shall be deemed a material default of this Lease:

          (a) Tenant's failure to complete, within the time periods required by
this Lease, any tasks required for the preparation or approval of plans for the
construction and/or completion of the Demised Premises prior to the Commencement
Date;

          (b) Tenant's failure to accept possession of the Demised Premises when
tendered by Landlord;

          (c) Tenant's failure to pay any installment of Base Annual Rent,
Additional Rent or other sum required to be paid by Tenant when the same shall
be due and payable, all without demand unless demand is necessary under the
express terms of this Lease (in which case a material default shall be deemed to
occur if such payment is not made strictly within the time period provided for
such payment following the demand);

          (d) Tenant's failure to perform or observe any other term, covenant or
condition of this Lease;

          (e) Any event expressly designated or deemed a default elsewhere in
this Lease;

          (f) Any execution, levy, attachment or other legal process of law
shall occur upon Tenant's Property, Tenant's interest in this Lease or the
Demised Premises;

          (g) Tenant's abandonment or surrender of the Demised Premises prior to
the expiration of the Lease Term and the suspension of rent payments as the same
may become due and payable; and/or

          (h) Tenant's committing or permitting waste to occur to the Demised
Premises.

     12.2 REMEDIES. In each and every such event set forth in Section 12.1
above, from the date of such default and at all times thereafter, at the option
of Landlord, Tenant's right of possession shall thereupon cease and terminate.
Landlord shall be entitled to all rights and remedies now or later allowed at
law or in equity, all of which shall be cumulative to the extent that the
exercise of any one or more rights or remedies shall not be deemed to constitute
a waiver of the Landlord's right to exercise any one or more other

                                       17

<PAGE>   68

rights and remedies herein provided or provided at law or in equity. Landlord
shall be entitled to obtain possession of the Demised Premises whether or not
Landlord elects to terminate this Lease, and to re-enter the same without
demand of rent or demand of possession of the Demised Premises and may forthwith
proceed to recover possession of the Demised Premises by any lawful means or
process of law whether or not Landlord elects to terminate this Lease, any
notice to quit being hereby expressly waived by Tenant. In the event of such
re-entry by process of law or otherwise, Tenant nevertheless agrees to remain
liable for all Base Annual Rent, Additional Rent and other sums due under this
Lease, and shall pay the same as and when it accrues and is payable hereunder.
Landlord may (but shall not be obligated to) declare the entire balance (or any
portion thereof) of Base Annual Rent, Additional Rent and all other sums payable
by Tenant hereunder for the remainder of the Lease Term to be immediately due
and payable in full, which shall be recoverable pursuant to Section 12.4 below.
Tenant further agrees to remain liable for any and all damage, deficiency, and
loss of Base Annual Rent, Additional Rent and other sums herein specified, and
all other damages which Landlord may sustain by such re-entry, including
reasonable attorneys' fees and costs. If under the provisions hereof, a seven
(7) days summons or other applicable summary process shall be served, and a
compromise or settlement thereof shall be made, such action shall not constitute
a waiver of any breach of any covenant, term, condition or agreement herein
contained.

     12.3 LANDLORD'S RIGHT TO RELET. Should this Lease be terminated before the
expiration of the Lease Term, by reason of Tenant's default as provided in
Sections 11 or 12, or if Tenant shall abandon the Demised Premises before the
expiration or termination of the Lease Term and without paying the rent due as
the same may become due and payable (whether or not Landlord elects to terminate
this Lease), the Demised Premises may be relet by Landlord, on Tenant's behalf
or for the account of Landlord, as Landlord so chooses, for such rent and upon
such terms as are reasonable under the circumstances. If the full rent reserved
under this Lease (and any of the costs, expenses or damages indicated below)
shall not be realized by Landlord, Tenant shall be liable for all damages
sustained by Landlord, including, without limitation, deficiency in Base Annual
Rent, Additional Rent, unamortized Landlord Concessions (hereinafter defined),
reasonable attorneys' fees, other collection costs, brokerage fees, expenses
incurred by Landlord to remove Tenant's Property and (at Landlord's option)
Leasehold Improvements, and expenses of placing the Demised Premises in
first-class rentable condition. Landlord, in putting the Demised Premises in
good order or preparing the same for reletting may, at Landlord's option, make
such alterations, repairs or replacements in or relating to the Demised Premises
as Landlord, in Landlord's sole judgment, considers advisable and necessary for
the purpose of reletting the Demised Premises, and the making of such
alterations, repairs or replacements shall not operate or be construed to
release Tenant from liability hereunder as aforesaid. Landlord shall in no event
be charged with any obligation to mitigate its damages nor shall Landlord be
liable in any way whatsoever for failure to relet the Demised Premises, or in
the event that the Demised Premises are relet, for failure to collect the rent
thereof under such reletting. For the purpose of calculating Landlord's damages
as set forth in Section 12.4 below, if the Building has other available space at
the time of such Lease termination or Tenant's abandonment or vacating of the
Demised Premises, or anytime thereafter, the Demised Premises shall be deemed
the last space rented in the Building even though the Demised Premises may be
re-rented by Landlord prior to such other vacant space. In no event shall Tenant
be entitled to receive any excess, if any, of rent (if any) collected over the
sums payable by Tenant to Landlord hereunder.

     12.4 RECOVERY OF DAMAGES.

          (a) Quantification of Damages. Any damage, deficiency, loss of Base
Annual Rent, Additional Rent or other sums payable by Tenant hereunder,
unamortized Landlord Concessions as described hereinafter, and all other damages
may be recovered by Landlord, at Landlord's option, upon default by Tenant, in
separate actions, from time to time, as said damage shall have periodically
accrued, or, at Landlord's option, may be deferred until the expiration of the
Lease Term (in which event Tenant hereby agrees that the cause of action shall
not be deemed to have accrued until the date of expiration of said Lease Term),
or, at Landlord's option, in a single action in the event Landlord shall have
declared the entire balance of Base Annual Rent, Additional Rent and other sums
due under this Lease immediately due and payable pursuant to Section 12.2. In
the event Landlord shall have declared the entire balance of Base Annual Rent,
Additional Rent and other sums due under this Lease immediately due and payable,
then in lieu of the Base Annual Rent and Additional Rent which would have been
payable for the period after the date of any judgment obtained in any action by
Landlord against Tenant to recover damages, Tenant shall pay a sum representing
liquidated damages, and not penalty, in an amount equal to the excess of (i) the
sum of the Base Annual Rent and Additional Rent provided for in this Lease for
the unexpired portion of the Lease Term after the date of judgment discounted at
a rate of three percent (3%) per annum to present value, over (ii) the rental
value of the Leased Premises, at the time of termination of this Lease, for the
unexpired portion of the Lease Term, discounted at a rate of three percent (3%)
per annum to present value. In determining the rental value of the Leased
Premises, the rent realized by any reletting accomplished or accepted by
Landlord within a reasonable time after termination of this Lease, shall be
deemed, prima facie, to be the rental value. In addition to all of the rights of
the Landlord to recover damages herein provided, Tenant shall immediately
reimburse Landlord for, and Landlord may recover, the unamortized portion of all
contributions and other concessions (hereinafter "Landlord Concessions"), if
any, provided by Landlord to Tenant as an inducement to enter into this Lease
and any amendment, modification or extension hereof and/or pursuant to the terms
of this Lease or any amendment, modification or extension hereof, including, but
not limited to, (i) any abatements or waivers of Base Annual Rent, Additional
Rent or other sums due under this Lease, (ii) costs incurred by Landlord in
making the Demised Premises ready for Tenant's occupancy, including the cost of
the Construction Improvements, any monetary contribution by Landlord for any
Leasehold Improvements and any other contributions by Landlord with respect to
any construction within or relating to the Demised Premises, (iii) moving
expenses, (iv) brokerage fees, (v) allowances for telephone and computer systems
and other office equipment and supplies, (vi) design, architectural and
engineering fees and expenses, and (vii) any other direct or indirect expenses
incurred by Landlord in conjunction with obtaining and/or entering into this
Lease and any amendment, modification and extension hereof, and placing and/or
retaining Tenant in possession of the Demised Premises. For purposes hereof, the
amount of any Landlord Concessions provided in connection with the initial Lease
Term shall be deemed to be amortized (using a straight-line method) on a monthly
basis over the initial Lease Term (excluding any extension or renewal terms) in
which Tenant is required to pay all or any portion of any installment of Base
Annual Rent under the terms of this Lease. The amount of any Landlord
Concessions provided in connection with any amendment or modification of this
Lease during the initial Lease Term shall be deemed to be amortized (using a
straight-line method) on a monthly basis over the remaining months in the
initial Lease Term (excluding any extension or renewal terms) in which Tenant is
required to pay all or any portion of any installment of Base Annual Rent under
the terms of this Lease. The amount of any Landlord Concessions provided in
connection with any renewal or extension of the Lease Term shall be deemed to be
amortized (using a straight-line method) on a monthly basis over the months in
the extension period (excluding any subsequent extension or renewal terms) in
which Tenant is required to pay all or any portion of any installment of Base
Annual Rent under the terms of said extension or renewal of the Lease Term.

            (b) Non-Exclusive Rights. The provisions contained in this Section
12.4 shall be in addition to and shall not prevent the enforcement of any claim
Landlord may have against Tenant for anticipatory breach of the unexpired Lease
Term. All rights and remedies of Landlord under this Lease shall be cumulative
and shall not be exclusive of any other rights and remedies provided to Landlord
under applicable law. In the event Tenant becomes the subject debtor in a case
under the Bankruptcy Code, the provisions of this Section 12.4 may be limited by
the limitations of damage provisions of the Bankruptcy Code.

      12.5 WAIVER. If under the provisions hereof Landlord shall institute
proceedings and a compromise or settlement thereof shall be made, the same shall
not constitute a waiver of any agreement, covenant, condition, rule or
regulation herein contained nor of any of Landlord's rights hereunder. No waiver
by Landlord of any breach of any agreement, covenant, condition, rule or
regulation herein contained, on one or more occasions, shall operate as a waiver
of such agreement, covenant, condition, rule or regulation itself, or of any
subsequent breach thereof. No provision of this Lease shall be deemed to have
been waived by Landlord unless such waiver shall be in writing signed by
Landlord. Receipt and acceptance by Landlord of any Base Annual Rent, Additional
Rent or other charges, or the performance of any obligation by Tenant hereunder,
with knowledge of the breach of any agreement, covenant, condition, rule or
regulation of this Lease by Tenant shall not be deemed a waiver of such breach.
Failure of Landlord to enforce any of the rules and regulations against Tenant
or any other tenant in the Building or Complex shall not be deemed a waiver of
any such rule or regulation. No payment by Tenant or receipt by Landlord of a
lesser amount than the Base Annual Rent and Additional Rent herein stipulated
shall be binding upon Landlord, nor shall the same be deemed to be other than on
account of the stipulated Base Annual Rent and Additional Rent. No endorsement
or statement on any check, letter or other transmittal accompanying any check or
payment of Base Annual Rent, Additional Rent or other sum due from Tenant shall
be deemed a settlement of a legal dispute or an accord and satisfaction, and
Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance of such Base Annual Rent, Additional Rent and other sums
or to pursue any other remedy provided in this Lease. Landlord's consent to, or
approval of, any act by Tenant requiring Landlord's consent or approval shall
not be deemed to waive or render unnecessary Landlord's consent to or approval
of any subsequent act by Tenant.

      12.6  ANTICIPATORY REPUDIATION.

            (a) Repudiation Prior to Commencement Date. If, prior to the
Commencement Date or the first day of any extension or renewal period set forth
in an extension or renewal option validly exercised by Tenant hereunder, Tenant
notifies Landlord of or otherwise unequivocally demonstrates an intention to
repudiate this Lease or breach any obligation of Tenant hereunder, Landlord may,
at its option, consider such anticipatory repudiation a breach and material
default of this Lease. In addition to any other remedies available to it
hereunder or at law or in equity, Landlord may retain all Base Annual Rent,
Additional Rent and other sums paid by Tenant hereunder, including any security
deposit, if any, to be applied to damages of Landlord incurred as a result of
such repudiation, including, without limitation, all damages and remedies
reserved to Landlord in this Section 12 or elsewhere in this Lease, as
applicable. It is agreed between the parties that for the purpose of calculating
Landlord's damages, if the Building has other available space at the time of or
subsequent to Tenant's breach, the Demised Premises covered by this Lease shall
be deemed the last space rented in the Building even though the Demised Premises
may be re-rented prior to such other vacant space. In the event a default occurs
prior to the Commencement Date, Tenant shall, in addition to all other damages
to which Landlord is entitled under this Lease, pay in full for all Leasehold
Improvements constructed or installed within the Demised Premises through the
date of the default, and for material ordered at Tenant's request for the
Demised Premises (whether at Tenant's request or upon Landlord's anticipation of
Tenant's needs hereunder) or for such material restocking charges.

            (b) Repudiation of Any Obligation of Tenant During Lease Term. If
during the Lease Term Tenant notifies Landlord of or otherwise unequivocally
demonstrates an intention to repudiate this Lease or breach any obligation of
Tenant hereunder, Landlord may, at its option, consider such anticipatory
repudiation a breach and material default of this Lease. In addition to any
other remedies available to it hereunder or at law or in equity, Landlord may
retain all Base Annual Rent, Additional Rent and other sums paid by Tenant
hereunder, including any security deposit, if any, to be applied to damages of
Landlord incurred as a result of such repudiation, including, without
limitation, all damages and remedies reserved to Landlord in this Section 12 or
elsewhere in this Lease, as applicable.

      12.7  TENANT ABANDONMENT OF DEMISED PREMISES.

            (a) Abandonment. If the Demised Premises or a substantial portion
thereof shall be deserted or vacated by Tenant for thirty (30) consecutive days
or more and Tenant shall be delinquent in the payment of any Base Annual Rent,
Additional Rent or other sums due under this Lease, or in the performance of any
of Tenant's other obligations hereunder, Landlord may deem the Tenant to have
abandoned the Demised Premises, notwithstanding the fact that Tenant may have
left all or some part of Tenant's Property thereon. Landlord may consider Tenant
in default under this Lease and may pursue all remedies available to it under
this Lease or otherwise as may be available in equity or at law.

            (b) Landlord Right to Enter and to Relet. If Tenant abandons the
Demised Premises as set forth in subsection (a) above, Landlord may, at its
option, enter into the Demised Premises without being liable for any prosecution
therefor or for damages by reason thereof. In addition to any other remedy
elsewhere provided in this Section 12 or at law or in equity, Landlord, as agent
of Tenant, may relet the whole or any part of the Demised Premises for the whole
or any part of the then unexpired Lease Term. For the purposes of such
reletting, Landlord may make any alterations or modifications of the Demised
Premises considered desirable in its sole judgment.

      12.8 TENANT'S PROPERTY. Tenant shall not remove any of Tenant's Property
from the Demised Premises without the prior written consent of Landlord, other
than in the ordinary course of Tenant's business. In the event of a default
under this Lease, Tenant shall not, under any circumstances, remove Tenant's
Property from the Demised Premises and Landlord may (but shall not be obligated
to) keep Tenant's Property in place (and require Tenant to return or replace
Tenant's Property to the extent Tenant removes same in violation of the terms of
this Lease) and use, or permit another occupant of the Demised Premises,
Building and/or Complex to use, Tenant's Property during the remainder of the
Lease Term (whether or not Landlord elects to terminate this Lease for such
default) at no cost, expense or liability to Landlord or such occupant. If
Tenant abandons the Demised Premises as defined in Section 12.7(a) above or
otherwise vacates the Demised Premises or otherwise defaults under this Lease,
any property that Tenant leaves within or related to the Demised Premises shall
be deemed to have been abandoned and, without liability to Tenant, may be
disposed of in the trash or retained by Landlord as the property of Landlord or
disposed of at public or private sale, or placed at the use of another occupant
in the Building or the Complex or any subsequent occupant in the Demised
Premises, as Landlord sees fit in its sole

                                       19


<PAGE>   70


discretion, all at no cost or expense to Landlord or such other person permitted
to use all or a portion of Tenant's Property hereunder, or Landlord may store
Tenant's Property at a location selected by Landlord in its sole discretion at
Tenant's sole cost and expense. The proceeds of any public or private sale of
Tenant's Property shall be applied by Landlord against (i) the expenses of
Landlord for removal, storage or sale of the property; (ii) the arrears of Base
Annual Rent, Additional Rent or other sums then or thereafter payable under this
Lease; and (iii) any other damages to which Landlord may be entitled hereunder.
At Landlord's option, at any time during the Lease Term after default by Tenant,
Landlord may require Tenant to forthwith remove Tenant's Property from the
Demised Premises. If Tenant vacates or abandons the Demised Premises, as defined
above, Landlord may transfer any of Tenant's Property to creditors of Tenant, on
presentation of evidence of a claim valid on its face of ownership or of a
security interest in any of Tenant's Property abandoned in the Demised Premises
or the Building, and Landlord may recover any costs incurred by Landlord in
doing so, all without incurring any liability to Tenant.

      12.9  LANDLORD'S LIEN.

            (a) Right of Distress/Landlord's Lien. To secure the payment of all
Base Annual Rent, Additional Rent and all other charges and sums that may become
due to Landlord under the terms of this Lease, Landlord shall have and is hereby
granted by Tenant a right of distress for rent, and a contractual first lien and
security interest upon all of Tenant's Property and all Leasehold Improvements,
and also upon all proceeds from the sale, transfer or other disposition of any
such property, and any replacements and substitutions thereof, and proceeds
thereof, and all proceeds of any insurance which may accrue to Tenant by reason
of damage to or destruction of any such property. All exemption laws are hereby
waived by Tenant. This lien is given in addition to Landlord's statutory and
common law liens and shall be cumulative thereto. "Leasehold Improvements" shall
be defined to mean all improvements installed or constructed within the Demised
Premises whether by or on behalf of either Landlord or Tenant (exclusive of
Tenant's trade fixtures), and as repaired, replaced, altered or improved from
time to time during the Lease Term, including without limitation, any
partitions, wall coverings, floors, floor coverings, ceilings, lighting
fixtures, and telephone, computer and/or data system wiring or other
improvements. "Tenant's Property" shall be defined to mean all of Tenant's trade
fixtures and all of Tenant's personal property, including, but not limited to,
all goods, wares, merchandise, inventory, furniture, machinery, equipment,
telecommunications and data transmission systems (and all their components
exclusive of wiring), business records, accounts receivables and other personal
property of Tenant in or about the Demised Premises or that may be placed or
kept therein during the Lease Term.

            (b) UCC Security Interest. This Lease shall also constitute a
security agreement under the Uniform Commercial Code of the District, State or
Commonwealth in which the Demised Premises are located. Upon the occurrence of
an event of default by Tenant under this Lease, Landlord shall have the option,
in addition to any other remedies provided herein or by law or at equity, to
enter the Demised Premises with or without the permission of Tenant and take
possession of any and all of Tenant's Property situated in or related to the
Demised Premises, without liability for trespass or conversion, and to enforce
the lien and security interest hereby granted in any manner provided by law.
Upon Landlord's request, Tenant will execute and deliver to Landlord UCC
Financing Statements to evidence the above-described lien in favor of Landlord.
Landlord shall be permitted from time to time to file such statements in the
appropriate City, County, District, State and/or Commonwealth offices to perfect
such lien. All expenses incurred by Landlord, including attorneys' fees, to
prepare and file such statements (and any extensions, renewals, assignments,
transfers, releases and terminations relating thereto) shall be immediately
reimbursed by Tenant upon demand. If Tenant fails to deliver such UCC Financing
Statements within ten (10) working days after Landlord's request, Tenant by such
failure irrevocably constitutes and appoints Landlord as its special
attorney-in-fact to execute and record the statements (and any extensions,
renewals, assignments, transfers, releases and terminations relating thereto),
the foregoing power of attorney being coupled with an interest.

            (c) UCC Remedies Not Mandatory. Notwithstanding anything herein to
the contrary, Landlord shall not be required to exercise any of its remedies
under the Uniform Commercial Code as a result of the security interest granted
to Landlord herein in lieu of any other right or remedy Landlord may have under
this Lease, at law or in equity, including without limitation the right to deem
any or all of Tenant's Property abandoned and/or dispose of it pursuant to the
provisions of Section 12.8.

      12.10 INJUNCTIVE RELIEF. In the event of a breach by Tenant of any of the
covenants or provisions hereof, Landlord shall have the right of injunction and
the right to invoke any remedy allowed at law or in equity as if re-entry,
summary proceedings and other remedies were not herein provided; and in such
event Landlord shall be entitled to recover from Tenant, payable as Additional
Rent hereunder, any and all reasonable expenses as Landlord may incur in
connection with its efforts to secure such injunctive relief or other remedy at
law or in equity, including all costs and reasonable attorneys' fees.

      12.11 INDEPENDENT COVENANTS. If Landlord shall commence any proceeding
based upon non-payment of Base Annual Rent, Additional Rent or any other sums of
any kind to which Landlord may be entitled or which it may claim hereunder,
Tenant will not interpose any counterclaim, set-off, recoupment or other defense
of any nature or description in any such proceeding. The parties hereto
specifically agree that Tenant's covenants to pay Base Annual Rent, Additional
Rent and any other sums required hereunder are independent of all other
covenants and agreements of Landlord herein contained; provided, however, that
this shall not be construed as a waiver of Tenant's right to assert such a claim
in any separate action brought by Tenant. Tenant further waives any right or
defense which it may have to claim a merger.

      12.12 WAIVER OF REDEMPTION. Tenant hereby expressly waives any and all
rights of redemption granted by or under any present or future laws in the
event of Tenant being evicted or dispossessed for any cause, or in the event of
Landlord obtaining possession or a judgment for or other right to possession of
the Demised Premises and/or Tenant's Property by reason of the violation by
Tenant of any of the covenants and conditions of this Lease, or otherwise.

      12.13 ATTORNEYS' FEES. The parties hereto agree that wherever in this
Lease the Landlord is entitled to collect its "attorney's fees", Landlord shall
be entitled to collect the entire amount of attorneys' fees actually incurred by
Landlord in enforcing its rights hereunder, and, wherever in this Lease the
Landlord is entitled to collect its "reasonable attorneys' fees", Landlord shall
be entitled to not less than twenty-five percent (25%) of any Base Annual Rent,
Additional Rent and/or other sums due Landlord in connection with the collection
thereof, as reasonable attorneys' fees and, in addition, with respect to actions
or claims pertaining to non-rent issues, Landlord shall be entitled to
reimbursement of the customary hourly billing rate of each attorney (and
non-attorney personnel working under such attorney's supervision) for the
reasonable time spent in enforcing (or attempting to enforce) any non-rent
obligation of Tenant hereunder, as reasonable attorneys' fees; provided,
however, the amount to be reimbursed by Tenant as attorneys' fees (reasonable or
otherwise) in any one matter shall never be less than One Thousand Dollars
($1,000).

                                       20

13.          SUBORDINATION

      13.1   SUBORDINATION. This Lease is subject and subordinate to all ground
or underlying leases and to all mortgages and/or deeds of trust and/or other
security interests (individually and collectively "mortgage") which may now or
hereafter affect the real property of which the Demised Premises form a part,
including all renewals, modifications, consolidations, replacements and
extensions thereof. This clause shall be self-operative and no further
instrument of subordination shall be required to effect this subordination.
Notwithstanding the foregoing, in confirmation of such subordination, Tenant
shall at Landlord's request execute and deliver to Landlord within ten (10)
business days after Landlord's request, any requisite or appropriate
certificate, subordination agreement or other document that may be reasonably
requested by Landlord or any other party requiring such certificate,
subordination agreement or document. If Tenant fails to execute such
certificate, subordination agreement or other document requested by Landlord or
other party within said ten (10) day period, Tenant by such failure irrevocably
constitutes and appoints Landlord as its special attorney-in-fact to execute
such certificate, subordination agreement or other document on Tenant's behalf,
the foregoing power-of-attorney being deemed to be coupled with an interest.
Notwithstanding the foregoing, any lessor under any ground or underlying lease
and the party secured by any mortgage affecting the real property of which the
Demised Premises are a part, or any renewal, modification, consolidation,
replacement or extension thereof, shall have the right to recognize this Lease
and, in the event of any cancellation or termination of such ground or
underlying lease, or any foreclosure under any mortgage, or any sale of the real
property at foreclosure sale, or any transfer of the real property by a deed in
lieu of foreclosure, this Lease shall continue in full force and effect at the
option of the lessor under such ground or underlying lease or, as applicable,
the party secured by such mortgage, or the purchaser at any foreclosure sale, or
the party taking the real property under a deed in lieu of foreclosure, such
party being hereby authorized by Tenant to exercise such option to cancel or
continue this Lease in such party's reasonable or unreasonable discretion.
Tenant hereby consents to the right of such party to effect the survival of this
Lease. Tenant agrees that neither the cancellation nor termination of any ground
or underlying lease, nor the foreclosure under any mortgage, nor the sale at
foreclosure, nor the transfer by a deed in lieu of foreclosure, shall, by
operation of law or otherwise, result in cancellation or termination of this
Lease or the obligations of Tenant hereunder, except in the sole option of the
party herein granted such option, which option may be exercised in said party's
reasonable or unreasonable discretion.

      13.2   ESTOPPEL CERTIFICATES. Tenant shall execute and return within ten
(10) business days any certificate that Landlord may request from time to time,
stating that this Lease is unmodified and in full force and effect, or in full
force and effect as modified, and stating the modification. The certificate also
shall state (a) the amount of the monthly installment of Base Annual Rent and
Additional Rent and the dates to which such rent has been paid in advance; (b)
the amount of any security deposit or prepaid rent; (c) that there is no present
default on the part of Landlord nor is there in existence any condition, event,
act or omission which with the giving of notice and/or the passage of time will
constitute a default on the part of Landlord, or attach a memorandum stating in
detail the factual circumstances of such default and/or the basis under the
Lease for such default; (d) that Tenant has no right to set-off or recoupment
and no defense or counterclaim against enforcement of its obligations under this
Lease; (e) that Tenant has no other notice of any sale, transfer or assignment
of this Lease or of the rentals; (f) that all Construction Improvements and
other work and improvements required of Landlord has been completed and that the
Construction Improvements and other work and improvements are complete and
satisfactory; (g) that Tenant is in full and complete possession of the Demised
Premises; (h) the date on which Tenant's rental obligations commenced (excluding
any periods of abatement) and the date to which such rent has been paid; (i)
that Tenant has not advanced any amounts to or on behalf of Landlord which have
not been reimbursed; (j) that Tenant understands that this Lease has been
collaterally assigned to Landlord's mortgagee as security for a loan to
Landlord; (k) that Base Annual Rent and Additional Rent may not be prepaid more
than one (1) month in advance without the prior written approval of Landlord's
mortgagee; and (l) such other items as Landlord may reasonably request. Failure
to deliver the certificate within the aforesaid ten (10) business day period
shall be conclusive upon Tenant for the benefit of Landlord and any successor to
or mortgagee or assignee of Landlord that this Lease is in full force and effect
and has not been modified except as may be represented by the party requesting
the certificate. If Tenant fails to deliver the certificate within the aforesaid
ten (10) business day period, Tenant by such failure irrevocably constitutes and
appoints Landlord as its special attorney-in-fact to execute and deliver the
certificate to any third party, the foregoing power of attorney being deemed to
be coupled with an interest.

      13.3   ATTORNMENT. Tenant covenants and agrees that, in the event any
ground lessor, lessor of any underlying lease or subsequent purchaser of the
Building so requests or in the event of any foreclosure under any mortgage, or
any renewal, modification, consolidation, replacement or extension thereof, or
in the event of a sale at foreclosure, or in the event of any acceptance of any
deed in lieu of foreclosure, which may now or hereafter affect the real property
of which the Demised Premises are a part, Tenant shall attorn to any ground
lessor, lessor of any underlying lease or subsequent purchaser of the Building
or to the party secured by such mortgage, or any renewal, modification,
consolidation, replacement or extension thereof, and to any purchaser at any
foreclosure sale or party taking a deed in lieu of foreclosure, and at the sole
option of such party, which option may be exercised in said party's reasonable
or unreasonable discretion, this Lease shall continue as a direct lease between
Tenant herein and such landlord or its successor. In any case, such landlord or
successor under such ground or underlying lease or such secured party or
purchaser at foreclosure sale or party taking a deed in lieu of foreclosure
shall not be bound by any prepayment on the part of Tenant of the Base Annual
Rent or Additional Rent for more than one month in advance, so that Base Annual
Rent and Additional Rent shall be payable under this Lease in accordance with
its terms, from the date of the termination or transfer of the ground or
underlying lease or the foreclosure under such mortgage, or the date of
foreclosure sale or transfer by deed in lieu of foreclosure, as if such
prepayment had not been made. Further, such landlord or successor in interest
shall not be liable for damages for any act or omission of Landlord or any prior
landlord or be subject to any recoupments, offsets, counterclaims or defenses
which Tenant may have against Landlord or any prior landlord. Tenant shall, upon
request of such landlord or successor landlord, execute and deliver an
instrument or instruments confirming Tenant's attornment.

      13.4   MORTGAGEE RIGHTS.

             (a) Mortgagee Requirements. Tenant shall, at its own expense,
comply with all reasonable notices of Landlord's mortgagee or other financial
institution providing funds which are secured by a mortgage placed on the whole
or any part of the real property of which the Demised Premises are a part,
respecting all matters of occupancy, use, condition or maintenance of the
Demised Premises, provided the same shall not unreasonably interfere with the
conduct of Tenant's business nor materially limit or affect the rights of the
parties under this Lease. Tenant shall, if so directed by Landlord's mortgagee
or such other financial institution in writing, pay all Base Annual Rent,
Additional Rent and other sums owed to Landlord directly to such mortgagee or
other financial institution. Notwithstanding acceptance and execution of this
Lease by the parties hereto, the terms hereof shall be automatically deemed
modified, if so required, for the purpose of complying with or fulfilling the
reasonable requirements of any mortgagee or trustee named or



                                       21

<PAGE>   72

secured by a mortgage that may now or hereafter be placed upon or secured by the
real property of which the Demised Premises are a part or any part thereof, or
any other financial institution providing funds to finance or refinance the real
property of which the Demised Premises are a part; provided, however, that such
modification(s) shall not be in material derogation or diminution of any of the
rights of the parties hereunder, nor materially increase any of the obligations
or liabilities of the parties hereunder.

             (b) Notices to Mortgagee. Tenant agrees to give Landlord's
mortgagee and any trustee named or secured by a mortgage a copy of any notice of
default served upon Landlord by Tenant, provided that prior to such notice
Tenant has been notified in writing (by way of Notice of Assignment of Rents and
Leases, or otherwise) of the names and addresses of such mortgagees and
trustees. Notice shall be provided to the mortgagees and trustees in the manner
prescribed in Section 24. Tenant further agrees that if Landlord shall have
failed to cure such default within the cure period provided in this Lease, if
any, then the mortgagees and trustees shall have an additional thirty (30) days
within which to cure such default, or if such default cannot be cured within
that time, then such additional time as may be necessary if within such thirty
(30) days such mortgagee or trustee has commenced and is diligently pursuing the
remedies necessary to cure such default (including, but not limited to,
commencement of foreclosure proceedings if necessary to effect such cure), in
which event Tenant shall not pursue its remedies while such cure is being
diligently pursued.

14.          TENANT'S HOLDOVER

      14.1   WITH LANDLORD CONSENT. If Tenant continues, with the knowledge and
written consent of Landlord obtained at least thirty (30) days prior to the
expiration of the Lease Term, to remain in the Demised Premises after the
expiration of the Lease Term, then Tenant shall, by virtue of said holdover
agreement, become a tenant from month-to-month at the rent stipulated by
Landlord in said consent, or if none is stipulated, at the monthly rate of Base
Annual Rent and Additional Rent last payable under this Lease (adjusted in
accordance with the provisions of this Lease as if the holdover period were
originally included herein), commencing said monthly tenancy with the first day
next following the end of the Lease Term. All other terms and conditions of this
Lease shall apply to any holdover period(s). Tenant shall give to Landlord at
least thirty (30) days written notice of any intention to quit the Demised
Premises. Tenant shall be entitled to thirty (30) days written notice from
Landlord to quit the Demised Premises, except in the event of nonpayment of the
monthly installment of Base Annual Rent and/or Additional Rent in advance or of
the breach of any other covenant, term or condition of this Lease by Tenant, in
which event Tenant shall not be entitled to any notice to quit, the usual thirty
(30) days notice to quit being hereby expressly waived by Tenant.

      14.2   WITHOUT LANDLORD CONSENT. In the event that Tenant, without the
written consent of Landlord, shall hold over beyond the expiration of the Lease
Term, then Tenant hereby waives all notice to quit and agrees to pay to Landlord
for the period that Tenant is in possession after the expiration of this Lease,
a monthly charge which is three times the total monthly installment of Base
Annual Rent and Additional Rent in effect during the last month of the Lease
Term. Tenant expressly agrees to reimburse, defend, indemnify and hold Landlord
and Landlord's Agent harmless from all loss and damages, direct and
consequential, which Landlord or Landlord's Agent may incur in connection with
or in defense of claims by other persons or entities against Landlord,
Landlord's Agent or otherwise arising out of the holding over by Tenant,
including without limitation reasonable attorneys' fees which may be incurred by
Landlord or Landlord's Agent in defense of such claims. Acceptance of Base
Annual Rent, Additional Rent or any other sums due from Tenant hereunder or the
performance by Tenant of its obligations hereunder subsequent to the expiration
of the Lease Term, shall not constitute consent to any holding over. Landlord
shall have the right to apply all payments received after the expiration date of
the Lease Term toward payment for use and occupancy of the Demised Premises
subsequent to the expiration of the Lease Term and toward any other sums owed by
Tenant to Landlord, regardless of how such payment(s) may be designated by
Tenant. Landlord, at its option, may forthwith re-enter and take possession of
the Demised Premises without process, or by any legal process in force.
Notwithstanding the foregoing, if Tenant holds over, without Landlord's written
consent, due to acts of God, riot, or war, then such holdover shall be at the
total monthly installment of Base Annual Rent and Additional Rent applicable to
the last month of the Lease Term (adjusted in accordance with the provisions of
this Lease as if the holdover period were originally included herein), for the
duration of the condition (but not to exceed ten (10) days), but such continued
occupancy shall not create any renewal of the term of this Lease nor shall it
create a tenancy from year-to-year, month-to-month, or otherwise, and Tenant
shall be liable for and shall indemnify, defend and hold harmless Landlord and
Landlord's Agent against any loss and damages suffered by Landlord or Landlord's
Agent as described above. Any holdover period during which the Landlord and
Tenant are negotiating the terms and conditions of any holdover tenancy, new
lease or other matter, and/or for which Landlord and Tenant have failed to reach
an agreement as to the rent to be paid during such holdover period, shall
conclusively be deemed to be a holdover without the consent of Landlord for the
purpose of determining the rental to be paid and the obligations to be performed
by Tenant during such period.

15.          SECURITY DEPOSIT

      Tenant shall deposit with Landlord or Landlord's Agent simultaneously with
the execution of this Lease, the amount stipulated in Section 1.6 as a security
deposit. Provided Tenant is not in default in the payment of Base Annual Rent,
Additional Rent or any other charges due Landlord, and further provided the
Demised Premises are left in good condition, reasonable wear and tear excepted,
as described in Section 6.10, said deposit (which shall not bear interest to
Tenant) shall be returned to Tenant within sixty (60) days after the termination
of this Lease. Notwithstanding the foregoing, the full or partial return by
Landlord to Tenant of the security deposit shall at no time be deemed to
constitute a waiver by Landlord of any of Tenant's obligations under this Lease,
nor an acknowledgment by Landlord that any such obligations are limited to the
amount, if any, of the security deposit retained by Landlord. If Tenant is in
default or is otherwise indebted to Landlord hereunder or if the Demised
Premises are not left in good condition, or if Tenant has failed or refused to
remove Tenant's Property after Landlord's request to do so, then the security
deposit shall be applied to the extent available on account of sums due Landlord
or the cost of repairing damages to the Demised Premises or to remove Tenant's
Property. In the event the funds deposited with Landlord as security are applied
during the Lease Term on account of sums due Landlord or to the cost of
repairing damages or removing Tenant's Property, then Tenant shall, within
fifteen (15) days after demand by Landlord, deposit with the Landlord additional
funds to restore the security deposit to its original amount. In the event of
the sale or transfer of Landlord's interest in the Building, Landlord shall have

16.          QUIET ENJOYMENT

      So long as Tenant shall observe and perform the covenants and agreements
binding on Tenant hereunder, Tenant shall at all times during the term herein
granted, peacefully and quietly have and enjoy possession of the Demised
Premises without any encumbrance or hindrance by, from or through Landlord,
except as provided for elsewhere under this Lease. Nothing in this Section shall
prevent Landlord from performing alterations, improvements or repairs on other
portions of the Building not leased to Tenant or from performing alterations,
improvements or repairs within the Demised Premises in accordance with the
provisions of this Lease, nor shall performance of alterations, improvements or
repairs by Landlord, Landlord's Agent or any other tenant of the Building be
construed as a breach of this covenant by Landlord.

17.          SUCCESSORS

      All rights, remedies and liabilities herein given to or imposed upon
either of the parties hereto, shall extend to their respective heirs, executors,
administrators, personal representatives, successors and assigns. This provision
shall not be deemed to grant Tenant any right to assign this Lease or to sublet
the Demised Premises.

18.          WAIVER OF JURY TRIAL AND STATUTE OF LIMITATIONS

      Landlord and Tenant (and any guarantors and other parties with liability
for the performance of any or all of Tenant's obligations hereunder, as well as
any subtenants, assignees and licensees of Tenant) hereby waive trial by jury in
any action, proceeding or counterclaim brought by either of the parties hereto
against the other or in respect of any matter whatsoever arising out of or in
any way connected with this Lease, the relationship of Landlord and Tenant
hereunder, Tenant's use or occupancy of the Demised Premises, and/or any claim
of injury or damage. Tenant (and any guarantors and other parties with liability
for the performance of any or all of Tenant's obligations hereunder, as well as
any subtenants, assignees and licensees of Tenant) hereby waives the benefit of
any statute of limitation or other law limiting or prohibiting Landlord from
bringing any claim against Tenant (and/or any guarantors and/or other parties
with liability for the performance of any or all of Tenant's obligations
hereunder, as well as any subtenants, assignees and licensees of Tenant) arising
from or related to this Lease, the relationship of Landlord and Tenant and/or
the performance of Tenant's obligations hereunder at any time. Tenant (and any
guarantors and other parties with liability for the performance of any or all of
Tenant's obligations hereunder, as well as any subtenants, assignees and
licensees of Tenant) hereby agrees to submit to the personal jurisdiction of any
court of competent jurisdiction within the state, or the District of Columbia if
applicable, in which the Demised Premises and/or Landlord's principal place of
business is located.

19.          LIMITATION OF LANDLORD'S LIABILITY; NOTICE

      19.1   LANDLORD'S CONSENT. Notwithstanding anything to the contrary
contained in this Lease, if any provision of this Lease expressly or impliedly
obligates Landlord not to unreasonably withhold its consent or approval, an
action for declaratory judgment or specific performance will be Tenant's sole
right and remedy in any dispute as to whether Landlord has breached such
obligation or is required to give consent or approval. In no event shall
Landlord be liable for damages for any withholding of, any delay in providing,
or the conditioning of, any consent or approval.

      19.2   INDIVIDUAL LIABILITY. Tenant acknowledges and agrees that the
liability of Landlord with respect to any claim arising out of, related to, or
under this Lease shall be limited solely to its interest in the Building. No
personal judgment shall lie against the Landlord nor any partner of a
partnership constituting Landlord (if Landlord is a partnership) nor any
shareholder of Landlord (if Landlord is a corporation), and none of the same
will be personally liable with respect to any claim arising out of or related to
this Lease. If the Landlord is a partnership, any deficit capital account of any
partner and any partner's obligation to contribute capital shall not be deemed
an asset of the partnership. In the event of sale or other transfer of the
Landlord's interest in the Demised Premises and/or Building, Landlord shall
thereupon and without further act by either party be deemed released from all
liability and obligations hereunder arising out of any act or omission relating
to the Demised Premises, the Building or this Lease, occurring subsequent to the
sale or other transfer. The provisions hereof shall inure to the benefit of
Landlord's successors and assigns, including any mortgagee or trustee under a
deed of trust. The foregoing provisions are not intended to relieve Landlord
from the performance of any of Landlord's obligations under this Lease, but only
to limit the personal liability of Landlord, and its partners or shareholders,
as the case may be; nor shall the foregoing be deemed to limit Tenant's rights
pursuant to this Lease to obtain injunctive relief or specific performance with
respect to any obligations of Landlord hereunder.

      19.3   NOTICE IN EVENT OF LANDLORD'S DEFAULT. Notwithstanding anything to
the contrary in this Lease, in no event shall Landlord be deemed to be in
default in the performance of any covenant, condition or agreement herein
contained unless Tenant shall have given Landlord written notice of such
default, and Landlord shall have failed to cure such default within thirty (30)
days after such notice (or if such default is of such nature that it cannot be
completely cured within said thirty (30) days, if Landlord fails to commence to
cure within said thirty (30) days and thereafter proceed with reasonable
diligence and in good faith to effect such cure).

20.          AUTHORITY

      Landlord and Tenant hereby covenant each for itself, that each has the
full right, power and authority to enter into this Lease upon the terms and
conditions herein set forth. If Tenant signs as a corporation, each of the
persons executing this Lease on behalf of Tenant does hereby covenant and
warrant that Tenant is and shall be throughout the Lease Term, a duly authorized
and existing corporation, qualified to do business in the jurisdiction in which
the Demised Premises are located and is in good standing, that the corporation
has full right and authority to enter into this Lease, and that each of the
persons signing on behalf of the corporation were authorized to do so. If Tenant
signs as a partnership, each of the persons executing this Lease on behalf of
Tenant does hereby covenant and warrant that Tenant is a duly formed and validly
existing partnership, qualified to do business in the jurisdiction in which the
Demised Premises are located, and is in good standing, that the partnership has
full right and authority to enter into this Lease, and that each of the persons
signing on behalf of the partnership were authorized to do so.

and (j) any other substances declared to be hazardous or toxic under Laws
(hereinafter defined) now or hereafter enacted or promulgated by any Authorities
(hereinafter defined).

      21.2   TENANT'S RESTRICTIONS. Tenant shall not cause or permit to occur:

             (a) Violations. Any violation of any federal, state and local laws,
ordinances, regulations, directives, orders, notices and requirements now or
hereafter enacted or promulgated regulating the use, generation, storage,
handling, transportation, or disposal of Hazardous Substances ("Laws"), now or
hereafter enacted, related to environmental conditions on, under, or about the
Demised Premises, the Building and/or the Complex, or arising from Tenant's use
or occupancy of the Demised Premises, Tenant's Property, or Leasehold
Improvements, including, but not limited to, soil and ground water conditions;
and/or

             (b) Use. The use, generation, release, manufacture, refining,
production, processing, storage, or disposal of any Hazardous Substances on,
under, or about the Demised Premises, the Building and/or the Complex, or the
transportation to or from the Demised Premises of any Hazardous Substances,
without the prior written consent of Landlord, such consent to be granted or
withheld in Landlord's sole and absolute discretion, and, if granted, Tenant's
activities shall be in strict compliance with all Laws.

      21.3   AFFIRMATIVE OBLIGATIONS.

             (a) Compliance with Laws. Tenant shall, at Tenant's own expense,
comply with all Laws. Tenant shall, at Tenant's own expense, make all
submissions to, provide all information required by, and comply with all
requirements of all federal, state and local governmental and regulatory
authorities (the "Authorities") under the Laws. Tenant shall promptly provide
Landlord with a copy of all such submissions and information requests.

             (b) Clean-Up Plans. Should any Authority or any third party demand
that a removal or clean-up plan be prepared and that a removal or clean-up be
undertaken because of any deposit, spill, discharge, release, misuse,
prohibition on continued use, act or failure to act with respect to any
Hazardous Substances relating to, occurring on or arising out of Tenant's use or
occupancy of the Demised Premises, Tenant's Property or Leasehold Improvements,
then Tenant shall, at Tenant's own expense, prepare and submit the required
plans and all related bonds and other financial assurances, and Tenant shall
carry out all such removal and clean-up plans within the time limits set by any
Authority or other party. Tenant shall promptly provide Landlord with copies of
notices received from any Authority or third party, and of all removal and
clean-up plans, bonds, and related matters.

             (c) Information Requests. Tenant shall promptly provide all
information regarding the use, generation, storage, transportation or disposal
of Hazardous Substances that is required hereunder or is requested by Landlord.
If Tenant fails to fulfill any duty imposed under this Section 21 within a
reasonable time (or any shorter period of time if so required by any Authority),
Landlord may (but shall not be obligated to) do so and all costs associated
therewith shall constitute Additional Rent hereunder and shall be immediately
due and payable to Landlord, together with interest thereon calculated at the
rate of twenty-four percent (24%) per annum. In such case, Tenant shall
cooperate with Landlord in order to prepare all documents Landlord deems
necessary or appropriate to determine the applicability of the Laws to the
Demised Premises, Tenant's use thereof and Tenant's Property and Leasehold
Improvements, and for compliance therewith, and Tenant shall execute all
documents promptly upon Landlord's request. No such action by Landlord and no
attempt made by Landlord to mitigate damages under any Laws shall constitute a
waiver of any of Tenant's obligations under this Section 21.

      21.4   TENANT'S INDEMNITY. Tenant shall indemnify, defend, and hold
harmless Landlord, Landlord's Agent, and their respective officers, directors,
beneficiaries, shareholders, partners, agents and employees from all fines,
suits, procedures, claims and actions of every kind, and all costs associated
therewith (including attorneys' and consultants' fees) arising out of or in any
way connected with any deposit, spill, discharge, release, misuse, prohibition
or continued use, act or failure to act, with respect to any Hazardous
Substances or other failure to comply with the Laws which arise at any time from
Tenant's use or occupancy of the Demised Premises or Tenant's Property or the
Leasehold Improvements, or from Tenant's failure to provide all information,
make all submissions, and take all steps required by all Authorities under the
Laws and all other related laws.

      21.5   SURVIVAL OF OBLIGATIONS. Tenant's obligations and liabilities under
this Section 21, and the obligations of all guarantors and other parties with
liability for the performance of any or all of Tenant's obligations hereunder,
shall survive the expiration or earlier termination of this Lease.

22.          JOINT AND SEVERAL LIABILITY

      In the event that two or more individuals, corporations, partnerships or
other business associations (or any combination of two or more thereof) shall
sign this Lease as Tenant or guarantee this Lease as guarantors or are otherwise
liable for the performance of any or all of Tenant's or any guarantor's
obligations, the liability of each such individual, corporation, partnership or
other business association to pay Base Annual Rent, Additional Rent and any
other sums due hereunder and to perform all or any other obligations hereunder
shall be deemed to be joint and several. In like manner, in the event that the
Tenant named in this Lease shall be a partnership or other business association,
the members of which are by virtue of statute or general law subject to personal
liability, then, and in that event, the liability of each such member shall be
deemed to be joint and several. Notwithstanding any other provisions hereof, or
of any rule or provisions of law, the failure or refusal by Landlord to proceed,
in the event of a breach or default by Tenant, against all the individuals,
corporations, partnerships or other business associations comprising the Tenant
(or any combination of two or more thereof) or against Tenant or against one or
more of the guarantors or other parties with liability for the performance of
any or all of Tenant's or any guarantor's obligations, shall not be deemed to be
a release or waiver of any rights which Landlord may possess against such other
individuals, corporations, partnerships or other business associations not so
proceeded against, nor shall the granting by Landlord of a release of, or
execution of a covenant not to sue, any one or more of the individuals,
corporations, partnerships, or other business associations comprising the Tenant
(or any combination of two or more thereof) or the guarantors or other parties
with liability for the performance of any or all of Tenant's or any guarantor's
obligations, constitute a release or waiver, in whole or in part, of any rights
which Landlord may possess against such other individuals, corporations,
partnerships, or associations not so released or granted a covenant not to sue.

28.          ENTIRE AGREEMENT; MODIFICATION

      This Lease, all Exhibits, and the Specific and Special Provisions
incorporated herein by reference are intended by the parties as a final
expression of their agreement and a complete and exclusive statement of the
terms thereof, all negotiations, considerations and representations between the
parties having been incorporated herein. No course of prior dealings between the
parties or their officers, partners, employees, agents or affiliates shall be

acknowledges that Landlord, Landlord's Agent and their respective agents and
employees made no representations, warranties, understandings or agreements
pertaining to the condition of the Building or the Demised Premises, or
otherwise, which have induced Tenant to execute, or have been relied upon by
Tenant in the execution of this Lease, other than those specifically set forth
herein. This Lease can be modified only by a writing signed by both parties
hereto. The language of this Lease shall in all cases be construed as a whole
and according to its fair meaning, and not strictly for or against either
Landlord or Tenant. The interpretation or construction of this Lease shall be
unaffected by any argument or claim, whether or not justified, that this Lease

committed to the discretion of Landlord, expressly states that Landlord shall
not withhold, delay, condition or exercise such consent, approval or discretion
unreasonably.

29.          GOVERNING LAW; SEVERABILITY

      This Lease shall be governed by and construed in accordance with the laws
of the State or District in which the Building is located. The unenforceability,
invalidity, or illegality of any provision herein shall not render any other
provision herein unenforceable, invalid, or illegal.

30.          BINDING EFFECT OF LEASE

      The submission of an unsigned copy of this document to Tenant for
examination or signature shall not constitute an option, reservation or offer to
lease space in the Building. This Lease shall become effective and binding only
upon execution and delivery by both Landlord and Tenant, and shall be
enforceable in accordance with its terms from and after the date this Lease is
fully executed and delivered by Landlord and Tenant.

reasonable control (whether similar or dissimilar to the foregoing named
events), then the time for performance of such obligation shall be excused for
the period of such delay or prevention and extended for a period equal to the

Lease or any memorandum hereof from record. Tenant irrevocably constitutes and

such instrument(s), the foregoing power of attorney being deemed to be coupled
with an interest.

33.          TIME OF ESSENCE

      Tenant acknowledges that time is of the essence in its performance of any
and all obligations, terms and provisions of this Lease.

34.          BROKERS

      Tenant represents and warrants that it did not retain, nor consult with,
any broker or real estate salesperson (other than Landlord's Agent) with respect

harmless from and against any claims for brokerage or other commissions and any
claim of, or right to, a lien under applicable law relating to real estate
broker liens, arising by reason of a breach by Tenant of the foregoing
representation and warranty. Tenant agrees to pay, or upon demand reimburse
Landlord and Landlord's Agent for, all costs and expenses, including attorneys'

       of the Lease or any law or ordinance governing such disposal. Tenant

       rules and regulations adopted by Landlord governing the use of the Common

       the general public, and Landlord shall in all cases retain the right to
       control or prevent access thereto by all persons whose presence, in the
       judgment of Landlord, shall be prejudicial to the safety, character,
       reputation or interests of the Building and its tenants. Tenant shall not

       decorations or installations or floor coverings by Tenant, any damage to
       the walls or floors shall be repaired by Tenant at Tenant's sole cost and
       expense. Tenant shall not lay linoleum or similar floor coverings so that

       sweepings, rubbish, rags, or toxic or flammable products, or other
       improper substances, therein. Tenant shall not waste water by interfering

       Tenant or any other person, nor contract with nor render free or paid

       Landlord's employees perform any such services, such employees shall be
       deemed to be the agents of Tenant regardless of whether or how payment is
       arranged for such services, and Tenant hereby indemnifies and holds

       services and any associated injury or damage to property or injury or

       combination locks on safes, safe cabinets, and other key-controlled

       Landlord. In the event of the loss of any key furnished to Tenant by
       Landlord, Tenant shall pay to Landlord the cost of replacing the same or
       of changing the lock or locks opened by such lost key if Landlord shall
       deem it necessary to make such a change. The word "key" as used herein
       shall refer to keys, keycards, and all such means of obtaining access

       technicians tendering any service to Tenant shall be referred by Tenant
       to Landlord for Landlord's supervision, approval and control before the
       performance of any contractual service. This provision shall apply to all
       work performed in the Building.

       or office equipment, or dispatch or receipt by Tenant of any bulky

       weight, stand on supporting devices approved by Landlord. All damages

       or done by Tenant's Property while in the Building, shall be repaired at
       the expense of Tenant.

       "Complex", "Building", "Demised Premises", "Tenant's Property" and
       "Systems" are defined in the Lease to which these rules and regulations
       are attached. Wherever these terms appear in the rules and regulations

       construed to in any way modify or amend, in whole or in part, the
       agreements, covenants, conditions and provisions of any lease of any
       premises in the Building.

day of January, 2000, by and between OTG Software, Inc., a Delaware corporation
(the "Corporation), and _______________ ("Indemnitee"), a director or officer of
the Corporation.

        WHEREAS, it is essential to the Corporation to retain and attract as
directors and officers the most capable persons available, and

        WHEREAS, the substantial increase in corporate litigation subjects
directors and officers to expensive litigation risks at the same time that the
availability of directors' and officers' liability insurance has been severely
limited, and

        WHEREAS, it is now and has always been the express policy of the
Corporation to indemnify its directors and officers so as to provide them with
the maximum possible protection permitted by law, and

        WHEREAS, Indemnitee does not regard the protection available under the
Corporation's Certificate of Incorporation and insurance as adequate in the
present circumstances, and may not be willing to serve as a director or officer
without adequate protection, and

        WHEREAS, the Corporation desires Indemnitee to serve as a director or
officer of the Corporation.

        NOW THEREFORE, the Corporation and Indemnitee do hereby agree as
follows:

        1.   Agreement to Serve. Indemnitee agrees to serve or continue to serve
as a director or officer of the Corporation for so long as he is duly elected or
appointed or until such time as he tenders his resignation in writing.

        2.   Definitions.  As used in this Agreement:

             (a) The term "Proceeding" shall include any threatened, pending
or completed action, suit, or proceeding, whether brought by or in the right of
the Corporation or otherwise and whether of a civil, criminal, administrative or
investigative nature, and any appeal therefrom.

             (b) The term "Corporate Status" shall mean the status of a person
who is or was a director or officer of the Corporation, or is or was serving, or
has agreed to serve, at the request of the Corporation, as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise.

<PAGE>   2

expenses of the types customarily incurred in connection with investigations,

amount of judgments, fines or penalties against Indemnitee or amounts paid in
settlement in connection with such matters.

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

        3.   Indemnification in Third-Party Proceedings. The Corporation shall
indemnify Indemnitee in accordance with the provisions of this Paragraph 3 if
Indemnitee was or is a party to or threatened to be made a party to or otherwise
involved in any Proceeding (other than a Proceeding by or in the right of the
Corporation to procure a judgment in its favor) by reason of his Corporate
Status or by reason of any action alleged to have been taken or omitted in
connection therewith, against all Expenses, judgments, fines, penalties and
amounts paid in settlement actually and reasonably incurred by Indemnitee or on
his behalf in connection with such Proceeding, if Indemnitee acted in good faith
and in a manner which he reasonably believed to be in, or not opposed to, the
best interests of the Corporation and, with respect to of any criminal
Proceeding, had no reasonable cause to believe that his conduct was unlawful.
The termination of any Proceeding by judgment, order, settlement, conviction or
upon a plea of nolo contendere, or its equivalent, shall not, of itself, create
a presumption that Indemnitee did not act in good faith and in a manner which he
reasonably believed to be in, or not opposed to, the best interests of the
Corporation, and, with respect to any criminal Proceeding, had reasonable cause
to believe that his conduct was unlawful.

        4.   Indemnification in Proceedings by or in the Right of the
Corporation. The Corporation shall indemnify Indemnitee in accordance with the
provisions of this Paragraph 4 if Indemnitee is a party to or threatened to be
made a party to or otherwise involved in any Proceeding by or in the right of
the Corporation to procure a judgment in its favor by reason of his Corporate
Status or by reason of any action alleged to have been taken or omitted in
connection therewith, against all Expenses and, to the extent permitted by law,
amounts paid in settlement actually and reasonably incurred by Indemnitee or on
his behalf in connection with such Proceeding, if he acted in good faith and in
a manner which he reasonably believed to be in, or not opposed to, the best
interests of the Corporation, except that no indemnification shall be made under
this Paragraph 4 in respect of any claim, issue, or matter as to which
Indemnitee shall have been adjudged to be liable to the Corporation, unless and
only to the extent that the Court of Chancery of Delaware shall determine upon
application that, despite the adjudication of such liability but in view of all
the circumstances of the case, Indemnitee is fairly and reasonably entitled to
indemnity for such Expenses as the Court of Chancery shall deem proper.

        5.   Exceptions to Right of Indemnification. Notwithstanding anything to
the contrary in this Agreement, except as set forth in Paragraph 10, the
Corporation shall not indemnify the



                                       -2-

<PAGE>   3

Indemnitee in connection with a Proceeding (or part thereof) initiated by the
Indemnitee unless the initiation thereof was approved by the Board of Directors
of the Corporation. Notwithstanding anything to the contrary in this Agreement,
the Corporation shall not indemnify the Indemnitee to the extent the Indemnitee
is reimbursed from the proceeds of insurance, and in the event the Corporation
makes any indemnification payments to the Indemnitee and the Indemnitee is
subsequently reimbursed from the proceeds of insurance, the Indemnitee shall
promptly refund such indemnification payments to the Corporation to the extent
of such insurance reimbursement.

        6.   Indemnification of Expenses of Successful Party. Notwithstanding
any other provision of this Agreement, to the extent that Indemnitee has been
successful, on the merits or otherwise, in defense of any Proceeding or in
defense of any claim, issue or matter therein, Indemnitee shall be indemnified
against all Expenses incurred by him or on his behalf in connection therewith.
Without limiting the foregoing, if any Proceeding or any claim, issue or matter
therein is disposed of, on the merits or otherwise (including a disposition
without prejudice), without (i) the disposition being adverse to the Indemnitee,
(ii) an adjudication that the Indemnitee was liable to the Corporation, (iii) a
plea of guilty or nolo contendere by the Indemnitee, (iv) an adjudication that
the Indemnitee did not act in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the Corporation, and (v) with
respect to any criminal proceeding, an adjudication that the Indemnitee had
reasonable cause to believe his conduct was unlawful, the Indemnitee shall be
considered for the purposes hereof to have been wholly successful with respect
thereto.

        7.   Notification and Defense of Claim. As a condition precedent to his
right to be indemnified, the Indemnitee must notify the Corporation in writing
as soon as practicable of any Proceeding for which indemnity will or could be
sought by him and provide the Corporation with a copy of any summons, citation,
subpoena, complaint, indictment, information or other document relating to such
Proceeding with which he is served. With respect to any Proceeding of which the
Corporation is so notified, the Corporation will be entitled to participate
therein at its own expense and/or to assume the defense thereof at its own
expense, with legal counsel reasonably acceptable to the Indemnitee. After
notice from the Corporation to the Indemnitee of its election so to assume such
defense, the Corporation shall not be liable to the Indemnitee for any legal or
other expenses subsequently incurred by the Indemnitee in connection with such
claim, other than as provided below in this Paragraph 7. The Indemnitee shall
have the right to employ his own counsel in connection with such claim, but the
fees and expenses of such counsel incurred after notice from the Corporation of
its assumption of the defense thereof shall be at the expense of the Indemnitee
unless (i) the employment of counsel by the Indemnitee has been authorized by
the Corporation, (ii) counsel to the Indemnitee shall have reasonably concluded
that there may be a conflict of interest or position on any significant issue
between the Corporation and the Indemnitee in the conduct of the defense of such
action or (iii) the Corporation shall not in fact have employed counsel to
assume the defense of such action, in each of which cases the fees and expenses
of counsel for the Indemnitee shall be at the expense of the Corporation, except
as otherwise expressly provided by this Agreement. The Corporation shall not be
entitled, without the consent of the Indemnitee, to assume the defense of any
claim brought by or in the right of the Corporation or as to which counsel for
the Indemnitee shall have reasonably made the conclusion provided for in clause
(ii) above.



                                       -3-

<PAGE>   4

        8.   Advancement of Expenses. Subject to the provisions of Paragraph 9
below, in the event that the Corporation does not assume the defense pursuant to
Paragraph 7 of this Agreement of any Proceeding to which Indemnitee was or is a
party or is threatened to be made a party by reason of his Corporate Status or
by reason of any action alleged to have been taken or omitted in connection
therewith and of which the Corporation receives notice under this Agreement, any
Expenses incurred by the Indemnitee in defending such Proceeding shall be paid
by the Corporation in advance of the final disposition of such matter; provided,
however, that the payment of such Expenses incurred by the Indemnitee in advance
of the final disposition of such matter shall be made only upon receipt of an
undertaking by or on behalf of the Indemnitee to repay all amounts so advanced
in the event that it shall ultimately be determined that the Indemnitee is not
entitled to be indemnified by the Corporation as authorized in this Agreement.
Such undertaking shall be accepted without reference to the financial ability of
the Indemnitee to make repayment.

        9.   Procedure for Indemnification. In order to obtain indemnification
or advancement of Expenses pursuant to Paragraphs 3, 4, 6 or 8 of this
Agreement, Indemnitee shall submit to the Corporation a written request,
including in such request such documentation and information as is reasonably
available to Indemnitee and is reasonably necessary to determine whether and to
what extent Indemnitee is entitled to indemnification or advancement of
Expenses. Any such indemnification or advancement of Expenses shall be made
promptly, and in any event within 60 days after receipt by the Corporation of
the written request of the Indemnitee, unless with respect to requests under
Paragraphs 3, 4 or 8 the Corporation determines within such 60-day period that
such Indemnitee did not meet the applicable standard of conduct set forth in
Paragraph 3 or 4, as the case may be. Such determination shall be made in each
instance by (a) a majority vote of the directors of the Corporation consisting
of persons who are not at that time parties to the Proceeding ("disinterested
directors"), whether or not a quorum, (b) a majority vote of a quorum of the
outstanding shares of stock of all classes entitled to vote for directors,
voting as a single class, which quorum shall consist of stockholders who are not
at that time parties to the Proceeding, (c) independent legal counsel (who may,
to the extent permitted by applicable law, be regular legal counsel to the
Corporation), or (d) a court of competent jurisdiction.

        10.  Remedies. The right to indemnification or advancement of Expenses
as provided by this Agreement shall be enforceable by the Indemnitee in any
court of competent jurisdiction if the Corporation denies such request, in whole
or in part, or if no disposition thereof is made within the 60-day period
referred to above in Paragraph 9. Unless otherwise required by law, the burden
of proving that indemnification is not appropriate shall be on the Corporation.
Neither the failure of the Corporation to have made a determination prior to the
commencement of such action that indemnification is proper in the circumstances
because Indemnitee has met the applicable standard of conduct, nor an actual
determination by the Corporation pursuant to Paragraph 9 that Indemnitee has not
met such applicable standard of conduct, shall be a defense to the action or
create a presumption that Indemnitee has not met the applicable standard of
conduct. Indemnitee's expenses (of the type described in the definition of
"Expenses" in Paragraph 2(c)) reasonably incurred in connection with
successfully establishing his right to indemnification, in whole or in part, in
any such Proceeding shall also be indemnified by the Corporation.



                                       -4-

<PAGE>   5

        11.  Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Corporation for some or a
portion of the Expenses, judgments, fines, penalties or amounts paid in
settlement actually and reasonably incurred by him or on his behalf in
connection with any Proceeding but not, however, for the total amount thereof,
the Corporation shall nevertheless indemnify Indemnitee for the portion of such
Expenses, judgments, fines, penalties or amounts paid in settlement to which
Indemnitee is entitled.

        12.  Subrogation. In the event of any payment under this Agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all papers required and take
all action necessary to secure such rights, including execution of such
documents as are necessary to enable the Corporation to bring suit to enforce
such rights.

        13.  Term of Agreement. This Agreement shall continue until and
terminate upon the later of (a) six years after the date that Indemnitee shall
have ceased to serve as a director or officer of the Corporation or, at the
request of the Corporation, as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise or (b) the
final termination of all Proceedings pending on the date set forth in clause (a)
in respect of which Indemnitee is granted rights of indemnification or
advancement of Expenses hereunder and of any proceeding commenced by Indemnitee
pursuant to Paragraph 10 of this Agreement relating thereto.

        14.  Indemnification Hereunder Not Exclusive. The indemnification and
advancement of Expenses provided by this Agreement shall not be deemed exclusive
of any other rights to which Indemnitee may be entitled under the Certification
of Incorporation, the By-Laws, any agreement, any vote of stockholders or
disinterested directors, the General Corporation Law of Delaware, any other law
(common or statutory), or otherwise, both as to action in his official capacity
and as to action in another capacity while holding office for the Corporation.
Nothing contained in this Agreement shall be deemed to prohibit the Corporation
from purchasing and maintaining insurance, at its expense, to protect itself or
the Indemnitee against any expense, liability or loss incurred by it or him in
any such capacity, or arising out of his status as such, whether or not the
Indemnitee would be indemnified against such expense, liability or loss under
this Agreement; provided that the Corporation shall not be liable under this
Agreement to make any payment of amounts otherwise indemnifiable hereunder if
and to the extent that Indemnitee has otherwise actually received such payment
under any insurance policy, contract, agreement or otherwise.

        15.  No Special Rights. Nothing herein shall confer upon Indemnitee any
right to continue to serve as an officer or director of the Corporation for any
period of time or at any particular rate of compensation.

        16.  Savings Clause. If this Agreement or any portion thereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
Corporation shall nevertheless indemnify Indemnitee as to Expenses, judgments,
fines, penalties and amounts paid in settlement with respect to any Proceeding
to the full extent permitted by any applicable portion of this



                                       -5-

<PAGE>   6

Agreement that shall not have been invalidated and to the fullest extent
permitted by applicable law.

        17.  Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall constitute the original.

        18.  Successors and Assigns. This Agreement shall be binding upon the
Corporation and its successors and assigns and shall inure to the benefit of the
estate, heirs, executors, administrators and personal representatives of
Indemnitee.

        19.  Headings. The headings of the paragraphs of this Agreement are
inserted for convenience only and shall not be deemed to constitute part of this
Agreement or to affect the construction thereof.

        20.  Modification and Waiver. This Agreement may be amended from time to
time to reflect changes in Delaware law or for other reasons. No supplement,
modification or amendment of this Agreement shall be binding unless executed in
writing by both of the parties hereto. No waiver of any of the provisions of
this Agreement shall be deemed or shall constitute a waiver of any other
provision hereof nor shall any such waiver constitute a continuing waiver.

        21.  Notices. All notices, requests, demands and other communications
hereunder shall be in writing and shall be deemed to have been given (i) when
delivered by hand or (ii) if mailed by certified or registered mail with postage
prepaid, on the third day after the date on which it is so mailed:

         The Employee hereby accepts such employment and agrees to undertake the
duties and responsibilities inherent in such position and such other duties and

establishes and makes available to employees or executives of the Company, to
the extent that Employee's position, tenure, salary, age, health and other
qualifications make him eligible to participate, which programs shall be as
favorable as those made available to employees of the Parent in comparable
positions. The Employee shall be entitled to four (4) weeks paid vacation per
year, to be taken at such times as may be approved by the Company or its
designee.

            3.3 Reimbursement of Expenses. The Company shall reimburse the
Employee for reasonable travel, entertainment and other expenses incurred or
paid by the Employee in connection with, or related to, the performance of his
duties, responsibilities or services under this Agreement, in accordance with
and subject to the terms of the policies of the Company.

         4. Employment Termination. The employment of the Employee by the
Company pursuant to this Agreement shall terminate upon the occurrence of any of
the following:

            4.1 Expiration of the Employment Period in accordance with
Section 1;

            4.2 At the election of the Company, for cause, immediately upon
written notice by the Company to the Employee. For the purposes of this Section
4.2, "Cause" for termination shall be deemed to exist solely upon the occurrence
of an event set forth in "Exhibit A to Executive Employment Agreement," which
has been attached hereto as Exhibit A; or

            4.3 Thirty (30) days after the death or disability of the Employee.
As used in this Agreement, the term "disability" shall mean the inability of the
Employee, due to a physical


                                       -3-


<PAGE>   4



or mental disability, for a period of ninety (90) consecutive days during any
360-day period to perform the services contemplated under this Agreement. A
determination of disability shall be made by a physician satisfactory to both
the Employee and the Company, provided that if the Employee and the Company do
not agree on a physician, the Employee and the Company shall each select a
physician and these two together shall select a third physician, whose
determination as to disability shall be binding on all parties.

            4.4 At the election of the Employee, upon not less than sixty (60)
days' prior written notice to the Company given promptly after the occurrence of
the event giving rise to such termination, in the event of the Company's taking
any of the following actions, which actions shall not have been cured within
such sixty (60)-day period: (a) material and adverse diminution, on a cumulative
basis, of the Employee's duties, authority, position, compensation (other than
bonus or other discretionary elements of the Employee's compensation) or
aggregate benefits, including, without limitation, failure to cause the Employee
to retain the positions of President and Chief Executive Officer of the Company;
(b) the failure of the Employee to be elected to and remain Chairman of the
Board throughout the Employment Period (provided the Employee is willing to
serve as such on the same terms and conditions as other employee-directors)
(unless the Employee is removed from the Board of Directors in connection with
the termination of the Employee's employment pursuant to Sections 4.2, 4.3, or
4.4 of this Agreement); or (c) the relocation (other than upon the Employee's
recommendation) of the Company's principal executive offices to a location more
than fifty (50) miles outside the city limits of Bethesda, Maryland.

         5. Effect of Termination.

<PAGE>   5




            5.1 Termination by the Company for Cause. In the event the
Employee's employment is terminated by the Company pursuant to Section 4.2, the
Company shall pay to the Employee the compensation and benefits otherwise
payable to him under Section 3 through the last day of his actual employment by
the Company.

            5.2 Termination by the Company Without Cause; Termination by the
Employee for Cause.

                (a) In the event the Employee's employment is terminated by the
Employee pursuant to Section 4.4, or by the Company for any reason other than
Cause as defined in Section 4.2 ("Without Cause") (each, a "Qualifying
Termination"), the Company shall pay or provide to the Employee the compensation
and benefits payable or provided to him under Section 3 through the last day of
his actual employment by the Company. If the Employee's employment is terminated
by the Employee pursuant to Section 4.4 or by the Company Without Cause, the
provisions of Section 6 shall cease to apply to the Employee as of the effective
date of termination.

                (b) In the event of a Qualifying Termination, the Company shall
make severance payments to the Employee in an amount equal to (A) the greater of
(1) the entire remaining portion of his compensation for the term of this
Agreement, or (2) the amount of his annual salary at the date of termination,
which amount is to be paid in equal increments over the twelve (12)-month
period commencing on the effective date of such termination, plus (B) in a lump
sum within ninety (90) days after the end of the applicable fiscal year, the
Annual Bonus that would otherwise have been paid to Employee for the fiscal year
in which such termination occurred.



                                       -5-


<PAGE>   6




                (c) The severance payment provided for in this Section 5.2 shall
be made in monthly installments on the first day of each calendar month. Such
installments shall be appropriately adjusted in the event a severance payment is
due for any partial calendar month.

                (d) Following any Qualifying Termination, the Company shall
continue to pay for or provide to the Employee the fringe benefits other than
health, disability and term life insurance benefits as may have been provided to
the Employee in accordance with Section 3.2 immediately prior to such Qualifying
Termination for a period ending on the earliest of (i) December 31, 2003, (ii)
the date of the Employee's employment by a third party on a substantially
full-time basis, (iii) the date six months after the effective date of such
Qualifying Termination, or (iv) the death of the Employee. Following any
Qualifying Termination, the Company shall continue to pay for or provide to the
Employee such health, disability and term life insurance benefits as may have
been provided to the Employee in accordance with Section 3.2 immediately prior
to such Qualifying Termination (subject to changes in the terms of such coverage
by the provider as may be applicable to the Company as a whole) for a period
ending on the earliest of (A) the date of the Employee's employment by a third
party on a substantially full-time basis, if such third party offers Employee
substantially comparable health, disability and term life insurance benefits on
at least as favorable terms, (B) the death of the Employee, or (C) December 31,
2003.

         The Employee shall notify the Company promptly following his acceptance
of any offer of employment by a third party. The Employee shall be under no
obligation to seek other employment following any Qualifying Termination, and
any amounts he earns in any other employment shall not reduce or offset the
severance payments or other amounts due hereunder except as specifically
provided in this Section 5.2(d).

           5.3 Termination for Death or Disability. In the event the
Employee's employment is terminated by death or because of disability pursuant
to Section 4.3 (a "Section 4.3 Termination"), the Company shall pay or provide
to the estate of the Employee or to the Employee, as the case may be, the
compensation and benefits payable or provided to him under Section 3 through the
last day of his employment by the Company as determined in accordance with
Section 4.3.

           5.4 Termination Upon Change in Control of the Company.

                (a) In the event the Employee's employment is terminated
pursuant to Section 4.4 or by the Company Without Cause within twelve (12)
months following a Change in Control (as defined below) of the Company, the
Company shall make a one-time lump sum severance payment (the "Change in Control
Severance Payment") to the Employee in an amount equal to the amount of
compensation due to the Employee under this Agreement for the remainder of the
term of this Agreement, if such payment would be greater than the amount
otherwise payable to Employee under Section 5.2(b). In such event, the Employee
shall not be entitled to the payments to which he would otherwise be entitled
pursuant to Section 5.2(b), but shall continue to be entitled to benefits
provided by the Company pursuant to and in accordance with Section 5.2(d).

                (b) The Change in Control Severance Payment payable under this
Section 5.4 shall be made without regard to whether the deductibility of such
payment (or any other "parachute payments," as that term is defined in Section
280G of the Internal Revenue Code of 1986, as amended (the "Code"), to or for
the Employee's benefit) would be limited or precluded by Section 280G and
without regard to whether such payments (or any other



                                       -7-



<PAGE>   8




"parachute payments" as so defined) would subject the Employee to the federal
excise tax levied on certain "excess parachute payments" under Section 4999 of
the Code.

                (c) Tax Adjustment Payments. If all or any portion of the amount
payable to Employee under this Agreement (together with all other payments of
cash or property, whether pursuant to this Agreement or otherwise, including,
without limitation, the issuance of options or shares or the granting, exercise
or termination of options therefor), constitutes "excess parachute payments"
within the meaning of Section 280G of the Code that are subject to the excise
tax imposed by Section 4999 of the Code (or any similar tax or assessment), the
amounts payable hereunder shall be increased to the extent necessary to place
Employee in the same after-tax position as he would have been in had no such tax
assessment been imposed on any such payment paid or payable to Employee under
this Agreement or any other payment that Employee may receive in connection
therewith. The determination of the amount of any such tax or assessment and the
incremental payment required hereby in connection therewith shall be made by the
accounting firm employed by the Company with thirty (30) calendar days after
such payment and said incremental payment shall be made within thirty (30)
business days after determination has been made. If, after the date upon which
the payment required by this Section 5.4(c) has been made, it is determined
(pursuant to final regulations or published rulings of the Internal Revenue
Service, final judgment of a court of competent jurisdiction, Internal Revenue
Service audit assessment, or otherwise) that the amount of excise or other
similar taxes or assessments payable by Employee is greater than the amount
initially so determined, then the Company shall pay Employee an amount equal to
the sum of (i) such additional excise or other taxes, plus (ii) any interest
fines and penalties resulting from such underpayment, plus (iii) an amount
necessary to reimburse Employee for any income, excise or other tax assessment
payable



                                      -8-



<PAGE>   9




by Employee with respect to the amounts specified in (i) and (ii) above, and the
reimbursement provided by this clause (iii), in the manner described above in
this Section 5.4(c). Payment thereof shall be made within ten (10) business days
after the date upon which such subsequent determination is made.

                (d) A "Change of Control" of the Company shall occur or be
deemed to have occurred in the event that:

                    (i) any "person", as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (a
"Person") other than the Company, any trustee or other fiduciary holding
securities under an employee benefit plan of the Company, or any corporation
owned directly or indirectly by the stockholders of the Company in substantially
the same proportion as their ownership of stock of the Company, acquires
"beneficial ownership" (as defined in Rule 13d-3 under the Exchange Act) of
securities of the Company representing fifty percent (50%) or more of the
combined voting power of the Company's then outstanding securities (other than
through an acquisition of securities directly from the Company);

                    (ii) individuals who, as of the date of this Agreement,
constitute the Board (the "Incumbent Board") cease for any reason to constitute
at least a majority of the Board; provided, however, that any individual
becoming a director subsequent to the date of this Agreement whose election, or
nomination for election by the Company's stockholders, was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board shall
be considered as though such individual were a member of the Incumbent Board,
but excluding, for this purpose, any such individual whose initial assumption of
office occurs as a result of an actual or threatened election contest with
respect to the election or

                                      -9-


<PAGE>   10




removal of directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board;

                   (iii) the stockholders of the Company approve a merger or
consolidation of the Company with any other corporation, other than (A) a merger
or consolidation which would result in the voting securities of the Company
outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the
surviving entity) more than fifty percent (50%) of the combined voting power of
the voting securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation or (B) a merger or consolidation
effected to implement a recapitalization of the Company (or similar transaction)
in which no Person acquires more than fifty percent (50%) of the combined voting
power of the Company's then outstanding securities; or

                   (iv) the stockholders of the Company approve a plan of
complete liquidation of the Company or an agreement for the sale or disposition
by the Company of all or substantially all of the Company's assets.

           5.5  Registration Rights.

                (a) In the event Employee is terminated pursuant to the
provisions of Sections 4.2, 4.4, 5.4(a), or Without Cause, Employee shall have
the right to require the Company to register under the Securities Act of 1933,
as amended ("Securities Act") any shares then held by him, either on a Form S-3
or a Form S-1 (or any successor forms thereto), within thirty (30) days from
the date of such termination. The Company shall pay all expenses in connection
with any such offering, except for underwriting discounts and expenses.


                                      -10-

<PAGE>   11




                (b) For the three (3) years following his termination for any
reason, the Employee shall have the right to require the Company, once in each
twelve (12)-month period, to register under the Securities Act any shares then
held by him either on a Form S-3 or a Form S-1 (or any successor forms thereto).
The Company shall pay all expenses in connection with any such offering, except
for underwriting discounts and expenses.

         6. Non-Compete.

                (a) During the Employment Period and for a period of two (2)
years after the termination or expiration thereof, the Employee will not
directly or indirectly:

                    (i) as an individual proprietor, partner, stockholder,
officer, employee, director, joint venturer, investor, lender, or in any other
capacity whatsoever (other than as the holder of not more than five percent (5%)
of the total outstanding stock of a publicly held company), engage in the
business (the "Restricted Business") of developing, producing, marketing,
selling or performing products or services of the kind or type developed or
being developed, produced, marketed, sold or performed by the Company while the
Employee was employed by the Company (provided that following the expiration or
termination of the Employment Period, (a) the Employee may act as an employee of
or consultant to a person or entity which engages in the Restricted Business so
long as the Employee does not himself engage in or assist the person or entity
in engaging in the Restricted Business by virtue of such employment or
consulting relationship; (b) the Employee may serve as a senior executive in a
corporation or other entity that has a division or subsidiary that reports to
the Employee and that engages in the Restricted Business if the Employee is no
more than nominally involved in the day-to-day operations or business practices
of such division or subsidiary; and (c) the Employee may provide investment
banking and any advisory services to corporations or other entities



                                      -11-



<PAGE>   12




engaged in the Restricted Business relating to financing, mergers, acquisitions
and dispositions); or

                    (ii) recruit, solicit or induce, or attempt to induce, any
employee or employees of the Company to terminate their employment with, or
otherwise cease their relationship with, the Company; or

                    (iii) divert or take away, or attempt to divert or to take
away, the business or patronage, of any of the clients, customers or accounts,
or prospective clients, customers or accounts, of the Company which were
contacted, solicited or served by the Employee while employed by the Company.

                (b) If any restriction set forth in this Section 6 is found by
any court of competent jurisdiction to be unenforceable because it extends for
too long a period of time or over too great a range of activities or in too
broad a geographic area, it shall be interpreted to extend only over the
maximum period of time, range of activities or geographic area as to which it
may be enforceable.

                (c) The restrictions contained in this Section 6 are necessary
for the protection of the business and goodwill of the Company and are
considered by the Employee to be reasonable for such purpose. The Employee
agrees that any breach of this Section 6 will cause the Company substantial and
irreparable damage and therefore, in the event of any such breach, in addition
to such other remedies which may be available, the Company shall have the right
to seek specific performance and injunctive relief.

         7. Inventions and Proprietary Information.

            7.1 Inventions.


                                      -12-

<PAGE>   13




                (a) All inventions, discoveries, computer programs, data,
technology, designs, innovations and improvements (whether or not patentable and
whether or not copyrightable) related to the business of the Company which are
made, conceived, reduced to practice, created, written, designed or developed by
the Employee, solely or jointly with others and whether during normal business
hours or otherwise, during his employment by the Company pursuant to this
Agreement ("Inventions") shall be the sole property of the Company. The Employee
hereby assigns to the Company all such Inventions and any and all related
patents, copyrights, trademarks, trade names, and other industrial and
intellectual property rights and applications therefor, in the United States and
elsewhere and appoints any officer of the Company as his duly authorized
attorney, but without any out-of-pocket expense to the Employee, to execute,
file, prosecute and protect the same before any government agency, court or
authority. The Employee hereby waives all claims to moral rights in any
Invention. Upon the request of the Company and at the Company's expense, the
Employee shall execute such further assignments, documents and other instruments
as may be necessary or desirable to assign fully and completely all such
Inventions to the Company and to assist the Company in applying for, obtaining
and enforcing patents or copyrights or other rights in the United States and in
any foreign country with respect to any such Invention.

                (b) The Employee shall promptly disclose to the Company all such
Inventions and will maintain adequate and current written records (in the form
of notes, sketches, drawings and as may be reasonably specified by the Company)
to document the conception and/or first actual reduction to practice of any such
Invention. Such written records shall be available to and remain the sole
property of the Company at all times.

         7.2 Proprietary Information.



                                      -13-




<PAGE>   14




                (a) The Employee acknowledges that his relationship with the
Company is one of high trust and confidence and that in the course of his
employment by the Company he will have access to and contact with Proprietary
Information. The Employee agrees that he will not, during the Employment Period
or at any time thereafter, disclose to others, or use for his benefit or the
benefit of others, any Proprietary Information or any Invention.

                (b) For purposes of this Agreement, Proprietary Information
shall mean all information (whether or not patentable and whether or not
copyrightable) owned, possessed or used by the Company, including, without
limitation, any Invention, formula, formation, vendor information, customer
information, apparatus, equipment, trade secret, process, research, report,
technical data, know-how, computer program, software, software documentation,
hardware design, technology, marketing or business plan, forecast, unpublished
financial statement, budget, license, price, cost and employee list that is
communicated to, learned of, developed or otherwise acquired by the Employee in
the course of his employment by the Company.

                (c) The Employee's obligations under this Section 7.2 shall not
apply to any information that (i) is or becomes known to the general public
under circumstances involving no breach by the Employee of the terms of this
Section 7.2, (ii) is generally disclosed to third parties by the Company without
restriction on such third parties, (iii) is approved for release by written
authorization of the Board or an authorized employee of the Company, (iv) is
communicated to the Employee by a third party under no duty of confidentiality
with respect to such information to the Company or another party, or (v) is
required to be disclosed by the Employee to comply with applicable laws,
governmental regulations, court order or subpoena, provided that the Employee
provides prior written notice of such disclosure to the Company and



                                      -14-



<PAGE>   15



an opportunity for the Company to object to such disclosure and further
provided that the Employee cooperates with the Company and takes reasonable and
lawful actions requested by the Company (the out-of-pocket costs of which shall
be paid by the Company) to avoid and/or minimize the extent of such disclosure.

                (d) Upon termination of this Agreement or at any other time upon
request by the Company, the Employee shall promptly deliver to the Company all
records, files, memoranda, notes, designs, data, reports, price lists, customer
lists, drawings, plans, computer programs, software, software documentation,
sketches, laboratory and research notebooks and other documents (and all copies
or reproductions of such materials in his possession or control) belonging to
the Company.

                (e) The Employee represents that the Employee's employment by
the Company and the performance by the Employee of his obligations under this
Agreement do not, and shall not, breach any agreement that obligates him to keep
in confidence any trade secrets or confidential or proprietary information of
his or of any other party or to refrain from competing, directly or indirectly,
with the business of any other party. The Employee shall not disclose to the
Company, and the Company shall not request that the Employee disclose, any trade
secrets or confidential or proprietary information of any other party.

                (f) The Employee acknowledges that the Company from time to time
may have agreements with other persons or with the United States Government, or
agencies thereof, that impose obligations or restrictions on the Company
regarding inventions made during the course of work under such agreements or
regarding the confidential nature of such work. If the Employee's duties
hereunder will require disclosures to be made to him subject to



                                      -15-


<PAGE>   16




such obligations and restrictions, the Employee agrees to be bound by them and
to take all action necessary to discharge the obligations of the Company under
such agreements.

           7.3 Remedies. The Employee acknowledges that any breach of the
provisions of this Section 7 shall result in serious and irreparable injury to
the Company for which the Company cannot be adequately compensated by monetary
damages alone. The Employee agrees, therefore, that, in addition to any other
remedy it may have, the Company shall be entitled to seek to enforce the
specific performance of this Agreement by the Employee and to seek both
temporary and permanent injunctive relief (to the extent permitted by law)
without the necessity of proving actual damages.

        8. Notices. All notices required or permitted under this Agreement shall
be in writing and shall be deemed effective upon personal delivery or upon
deposit in the United States Post Office, by registered or certified mail,
postage prepaid, addressed to the other party at the address shown above, or at
such other address or addresses as either party shall designate to the other in
accordance with this Section 8.

        9. Pronouns. Whenever the context may require, any pronouns used in
this Agreement shall include the corresponding masculine, feminine or neuter
forms, and the singular forms of nouns and pronouns shall include the plural,
and vice versa.

        10. Entire Agreement. This Agreement constitutes the entire agreement
between the parties and supersedes all prior agreements and understandings,
whether written or oral, relating to the subject matter of this Agreement,
including but not limited to that certain Employment Agreement dated June 9,
1998 by and between Employee and Company.

        11. Amendment. This Agreement may be amended or modified only by a
written instrument executed by both the Company and the Employee.

                                      -16-


<PAGE>   17




        12. Governing Law. This Agreement shall be construed, interpreted and
enforced in accordance with the laws of the State of Maryland.

        13. Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of both parties and their respective successors and
assigns, including any corporation with which or into which the Company may be
merged or which may succeed to its assets or business, provided, however, that
the obligations of the Employee are personal and shall not be assigned by him.

        14. Survival. The provisions of Sections 5, 6 and 7 shall survive the
termination of this Agreement.

        15. Miscellaneous.

            15.1 No delay or omission by either party in exercising any right
under this Agreement shall operate as a waiver of that or any other right. A
waiver or consent given by either party on any one occasion shall be effective
only in that instance and shall not be construed as a bar or waiver of any right
on any other occasion.

            15.2 The captions of the sections of this Agreement are for
convenience of reference only and in no way define, limit or affect the scope or
substance of any section of this Agreement.

            15.3 In case any provision of this Agreement shall be invalid,
illegal or otherwise unenforceable, the validity, legality and enforceability of
the remaining provisions shall in no way be affected or impaired thereby.

2.1      BASE SALARY. Executive shall be compensated by the payment of $165,000
         per annum ("Base Salary") in accordance with the Corporation's standard
         payroll practices for Executives at his level. Executive understands
         that all compensation paid shall be subject to the usual and customary
         federal and state tax withholding and other employment taxes as
         required by law. In the event Executive is terminated For Cause as
         defined in section 3.2 hereof, all compensation shall be prorated
         through the last day of Executive's employment if the "For Cause"
         termination is other than at the end of a calendar month.

         Executive will receive a salary review on January 1, 1999, and annually
         thereafter at the commencement of each calendar year. Any increase in
         the Base Salary will be based on the Corporation's performance as well
         as his individual contribution to that performance, and shall be
         determined at the sole discretion of the Corporation's CEO and Board of
         Directors.

2.2      BONUS COMPENSATION. In addition to the Base Salary, Executive shall
         receive a bonus equal to 25% of Base Salary ("Executive's Bonus")
         payable on a semi annual basis after the Effective Date of this
         agreement. Executive will receive a salary review on January 1, 1999,
         and annually thereafter at the commencement of each calendar year. Any
         increase in Executive's Bonus calculation will be based on the
         Executive's performance, and shall be determined at the sole discretion
         of the Corporation's Board of Directors.

2.3      STOCK OPTION/EMPLOYEE EQUITY PLANS. In addition to the foregoing
         compensation, and subject to approval of the Corporation's Board of
         Directors, and in full compliance with all applicable state and federal
         securities laws, Executive shall also be issued options at the
         effective date of the adoption of a plan to purchase up to 1.4% of the
         sum of i.) shares of the issued and outstanding Common Stock of the
         Corporation and ii.) options authorized under any option plans or other
         option or warrant provisions of the Corporation (which together are
         hereinafter referred collectively to as the "Stock") upon the following
         terms and conditions (the "Initial Stock Options"). Such Initial Stock
         Options shall not be considered anti dilutive with regards to an
         initial public offering which is registered with the SEC pursuant to
         the Securities Act of 1933, but shall be considered "anti dilutive" in
         relationship only to ABS Capital transactions and to other equity
         transactions that result in dilution to shareholders by more than 15%,
         such that additional grants of stock options shall be made to Executive
         at the then effective fair market values as to cause his percentage
         ownership to remain at 1.4% of the combination of the "Stock" plus any
         additional stock issued or options or warrants authorized. Subject to
         the vesting requirements set forth herein, the Initial Stock Options
         shall be exercisable for ten (10) years after the Effective Date
         regardless of Executive's employment status with the Corporation.
         Executive expressly understands that the Stock will be "restricted
         stock," and may not be traded or sold except subject to applicable
         state and federal securities laws. Corporation represents and agrees
         that it will use best efforts to cause Initial Stock Options to be
         registered following an initial public offering by the Corporation.


Page 4


<PAGE>   5


         The exercise price of the Initial Stock Options will be at the purchase
         price equal to that implicit in the Corporation's current financing
         transaction with ABS Capital, et al. The Initial Stock Options will
         vest 8% on March 1, 1999, 25% on the first anniversary of the Effective
         Date of this agreement, and 1.86111% in equal monthly amounts on a
         monthly basis over the 36 months following the first anniversary of
         this agreement. Notwithstanding the above, 100% of the Executive's
         Initial Stock Option shall vest in the event that the Corporation has a
         Change of Control. A "Change of Control" for purposes of this agreement
         shall be defined as a sale of more than 50% of the Corporation's stock
         or of the majority of the Corporation's operating assets to a third
         party. Except as otherwise expressly provided herein, the Initial Stock
         Options shall not be deemed earned for any vesting period after
         Executive voluntarily leaves the Corporation's employ or for any period
         after Executive is terminated For Cause as defined in section 3.2
         hereof.

         The Corporation anticipates that it will formulate and implement other
         Stock Option Plans and bonus plans in which Executives of the
         Corporation will participate. While not yet formal, if and when such
         plans are established by the Corporation, the Executive will be
         included along with other key executive members of the Corporation and
         its operating affiliates and shall participate as determined by the
         Corporation's Board of Directors and/or the appropriate Corporation
         committee charged with the responsibility of administering the Plan(s).

                  pursuing any other remedy for such breach or threatened
                  breach, including the recovery of damages from Executive.

         such statutory or regulatory provision; and the invalidity or
         unenforceability of any provision hereof shall not affect the validity
         or enforceability of any other provision. The remaining provisions
         shall remain in full force and effect as if the Agreement had been
         executed with the invalid or unenforceable provisions eliminated.

7.5      ENTIRE AGREEMENT. This Agreement, together with Exhibit A hereto,
         constitutes the entire understanding between the Corporation and
         Executive with respect to the subject matter hereof and supersedes any
         and all previous agreements and understandings between Executive and
         the Corporation concerning the subject matter hereof.

7.6      NON-DISCLOSURE. Executive shall not disclose or confirm to any third
         party the existence of, or any material term contained in, this
         Agreement (other than disclosure and discussion with legal counsel,
         accountants,  Executive's immediate family or such other professional,
         governmental unit or court as is reasonably deemed necessary by
         Executive, which is permitted); and any such non permitted disclosure,
         if due to the Executive's actual willful act or gross negligence, shall
         subject the Executive to termination for cause pursuant to Section
         1.4.2 above.

7.7      COUNTERPARTS. This Employment Agreement 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. This
         Employment Agreement shall become effective upon the execution of
         counterpart hereof by each of the parties hereto.

(the "Agreement") between the undersigned Ronald W. Kaiser ("Executive") and
Optical Technology Group, Inc. d/b/a OTG Software, now known as OTG Software,
Inc. (the "Company"). The second sentence of Section 2.3 of the Agreement
provides to the Executive certain rights to be granted additional options to
purchase stock of the Company under circumstances specified therein (the
"Antidilution Rights"). In order to facilitate an initial public offering of
the common stock of the Company, which the executive acknowledges will increase
the value of his existing stock options, and for other good and valuable
consideration, the Executive hereby (a) acknowledges that no events have
occurred as of the date of this letter that have triggered or would trigger his
Antidilution Rights, (b) agrees that the Antidilution Rights do not apply to
and are not triggered by a registered initial public offering of common stock
by the Company (an "IPO") and (c) agrees that the Antidilution Rights will
terminate upon the closing of an IPO.

     Except as modified hereby, the Agreement is hereby confirmed to be in full
force and effect. Please indicate your agreement to the modifications of the
Agreement set forth above by signing the enclosed copy of this letter and
returning it to the undersigned.

                          REGISTRATION RIGHTS AGREEMENT

This Agreement dated as of June 9, 1998, is entered into by and among Optical

("Kay"), F. William Caple ("Caple"), Alexandra Kay ("A. Kay") and ABS Capital
Partners II, L.P., Michael P. Murray and Greylock IX Limited Partnership (the

WHEREAS, the Company and the Purchasers have entered into a Note Purchase

arrangements with respect to the registration of shares of capital stock of the
Company under the Securities Act of 1933;

NOW, THEREFORE, in consideration of the mutual promises and covenants contained

     1.   Certain Definitions. As used in this Agreement, the following terms
shall have the following respective meanings:

          "Commission" means the Securities and Exchange Commission, or any
other Federal agency at the time administering the Securities Act.

splits, stock dividends, reclassifications, or similar events); provided,
however, that shares of Common Stock that are Existing Holders Registrable
Shares shall cease to be Existing Holders Registrable Shares (i) upon any sale
pursuant to a Registration Statement or Rule 144 under the Securities Act, (ii)
on the date that is two (2) years from the date when such shares may be sold
under Rule 144(k) under the Securities Act or (iii) upon any sale in any manner
to a person or entity which, by virtue of Section 14 of this Agreement, is not
entitled to the rights provided by this Agreement.

          "Notes" shall have the meaning specified in Subsection 1.2 of the

<PAGE>   2

          "Purchaser Registrable Shares" means (i) the shares of Common Stock
issued or issuable upon conversion of the Notes and (ii) any other shares of
Common Stock issued in respect of such shares (because of stock splits, stock
dividends, reclassifications, recapitalizations, or similar events); provided,
however, that shares of Common Stock which are Purchaser Registrable Shares
shall cease to be Registrable Shares (i) upon any sale pursuant to a
Registration Statement or Rule 144 under the Securities Act, (ii) on the date
that is two (2) years from the date when such shares are eligible for sale under
Rule 144(k) under the Securities Act or (iii) upon any sale in any manner to a
person or entity not entitled to the rights provided by this Agreement. Wherever
reference is made in this Agreement to a request or consent of holders of a
certain percentage of Registrable Shares, the determination of such percentage
shall include shares of Common Stock issuable upon conversion of the Notes even
if such conversion has not yet been effected.

          "Registration Statement" means a registration statement filed by the
Company with the Commission for a public offering and sale of Common Stock
(other than a registration statement on Form S-8 or Form S-4, or their
successors, or any other form for a similar limited purpose, or any registration
statement covering only securities proposed to be issued in exchange for
securities or assets of another corporation).

          "Registration Expenses" means the expenses described in Section 5.

          "Registrable Shares" means collectively the Existing Holders
Registrable Shares and the Purchaser Registrable Shares.

similar Federal statute, and the rules and regulations of the Commission issued
under such Act, as they each may, from time to time, be in effect.

          "Stockholders" means collectively the Existing Holders and the
Purchasers.

     2.   Required Registrations.

          (a)  At any time after the earlier of June 9, 2000, or the closing of
the Company's first underwritten public offering of shares of Common Stock
pursuant to a Registration Statement, (i) a Stockholder or Stockholders holding
in the aggregate at least 50% of the Existing Holders Registrable Shares may
request, in writing, that the Company effect the registration on Form S-1 or
Form S-2 (or any successor form) of Existing Holders Registrable Shares owned by
such Stockholder or Stockholders that is either at least 25% of the Existing
Holders Registrable Shares or with an aggregate offering price of at least
$10,000,000 (based on the then-current market price or the reasonably
anticipated price to the public) and (ii) a Stockholder or Stockholders holding
in the aggregate at least 50% of the Purchaser Registrable Shares may request,
in writing, that the Company effect the registration on Form S-1 or Form S-2 (or
any successor form) of Purchaser Registrable Shares owned by such Stockholder or
Stockholders that is either at least 25% of the Purchaser Registrable Shares or
with an aggregate



                                      -2-
<PAGE>   3

offering price of at least $10,000,000 (based on the then-current market price
or the reasonably anticipated price to the public). If the holders initiating
the registration intend to distribute the Registrable Shares by means of an
underwriting, they shall so advise the Company in their request and the Company
shall have the right to approve the underwriter, which approval shall not be
unreasonably withheld. In the event such registration is underwritten, the right
of other Stockholders to participate shall be conditioned on such other
Stockholders' participation in such underwriting. Upon receipt of any such
request, the Company shall promptly give written notice of such proposed
registration to all Stockholders. Such Stockholders shall have the right, by
giving written notice to the Company within 30 days after the Company provides
its notice, to elect to have included in such registration such of their
Registrable Shares as such Stockholders may request in such notice of election;
provided that if the underwriter (if any) managing the offering determines that,
because of marketing factors, all of the Registrable Shares requested to be
registered by all Stockholders may not be included in the offering, then all
Stockholders who have requested registration shall participate in the
registration pro rata based upon the number of Registrable Shares which they
have requested to be so registered. Thereupon, the Company shall, as
expeditiously as possible, use its best efforts to effect the registration on
Form S-1 or Form S-2 (or any successor form) of all Registrable Shares which the
Company has been requested to so register.

          (b)  At any time after the Company becomes eligible to file a
Registration Statement on Form S-3 (or any successor form relating to secondary
offerings), a Stockholder or Stockholders may request the Company, in writing,
to effect the registration on Form S-3 (or such successor form), of Registrable
Shares having an aggregate offering price of at least $1,000,000 (based on the
then current public market price). Upon receipt of any such request, the Company
shall promptly give written notice of such proposed registration to all
Stockholders. Such Stockholders shall have the right, by giving written notice
to the Company within 30 days after the Company provides its notice, to elect to
have included in such registration such of their Registrable Shares as such
Stockholders may request in such notice of election; provided that if the
underwriter (if any) managing the offering determines that, because of marketing
factors, all of the Registrable Shares requested to be registered by all
Stockholders may not be included in the offering, then all Stockholders who have
requested registration shall participate in the registration pro rata based upon
the number of Registrable Shares which they have requested to be so registered.
Thereupon, the Company shall, as expeditiously as possible, use its best efforts
to effect the registration on Form S-3 (or such successor form) of all
Registrable Shares which the Company has been requested to so register. The
Company shall have the right to approve any underwriter, which approval shall
not be unreasonably withheld (if any) chosen to underwrite any such registration
on Form S-3 (or any such successor form).

          (c)  The Company shall not be required to (i) effect at the request of
any holder of Existing Holders Registrable Shares more than three registrations
pursuant to paragraph (a) above or more than three registrations pursuant to
paragraph (b) above or (ii) to effect at the request of any holder of Purchaser
Registrable Shares more than three registrations pursuant to paragraph (a) above
or more than three registrations pursuant to paragraph (b) above. In addition,
the Company shall not be required to effect any registration (other than on Form
S-3 or any successor form relating to secondary offerings) within six months
after the effective date of any other Registration Statement of the Company,
except that such time period will be twelve months in the case of an initial
public offering of shares by the Company.

                                      -3-
<PAGE>   4

          (d)  If at the time of any request to register Registrable Shares
pursuant to this Section 2, the Company is engaged or has fixed plans to engage
within 30 days of the time of the request in a registered public offering as to
which the Stockholders may include Registrable Shares pursuant to Section 3 or
is engaged in any other activity which, in the good faith determination of the
Company's Board of Directors, would be adversely affected by the requested
registration to the material detriment of the Company, then the Company may at
its option direct that such request be delayed for a period not in excess of 150
days from the effective date of such offering or the date of commencement of
such other material activity, as the case may be, such right to delay a request
to be exercised by the Company not more than once in any one-year period.

     3.   Incidental Registration.

          (a)  Whenever the Company proposes to file a Registration Statement
(other than pursuant to Section 2) at any time and from time to time, it will,
prior to such filing, give written notice to all Stockholders of its intention
to do so and, upon the written request of a Stockholder or Stockholders given
within 20 days after the Company provides such notice (which request shall state
the intended method of disposition of such Registrable Shares), the Company
shall use its best efforts to cause all Registrable Shares which the Company has
been requested by such Stockholder or Stockholders to prepare and file with the
Commission a Registration Statement with respect to such Registrable Shares to
the extent necessary to permit their sale or other disposition in accordance
with the intended methods of distribution specified in the request of such
Stockholder or Stockholders and use its best efforts to cause the Registration
Statement to become effective as soon as reasonably practicable thereafter;
provided that the Company shall have the right to postpone or withdraw any
registration effected pursuant to this Section 3 without obligation to any
Stockholder.

          (b)  In connection with any registration under this Section 3
involving an underwriting, the Company shall not be required to include any
Registrable Shares in such registration unless the holders thereof accept the
terms of the underwriting as agreed upon between the Company and the
underwriters selected by it (provided that such terms must be consistent with
this Agreement). If in the opinion of the managing underwriter it is appropriate
because of marketing factors to limit the number of Registrable Shares to be
included in the offering, then the Company shall be required to include in the
registration only that number of Registrable Shares, if any, which the managing
underwriter believes should be included therein; provided that no persons or
entities other than the Company and the Stockholders shall be permitted to
include securities in the offering. If the number of Registrable Shares to be
included in the offering in accordance with the foregoing is less than the total
number of shares which the holders of Registrable Shares have requested to be
included, then the holders of Registrable Shares who have requested registration
and other holders of securities entitled to include them in such registration
shall participate in the registration pro rata based upon the number of
Registrable Shares which they have requested to be so registered. If any holder
would thus be entitled to include more securities than such holder requested to
be registered, the excess shall be allocated among other requesting holders pro
rata in the manner described in the preceding sentence.



                                      -4-
<PAGE>   5

     4.   Registration Procedures. If and whenever the Company is required by
the provisions of this Agreement to use its best efforts to effect the
registration of any of the Registrable Shares under the Securities Act, the
Company shall:

          (a)  file with the Commission a Registration Statement with respect to
such Registrable Shares and use its best efforts to cause that Registration
Statement to become and remain effective;

          (b)  as expeditiously as possible prepare and file with the Commission
any amendments and supplements to the Registration Statement and the prospectus
included in the Registration Statement as may be necessary to keep the
Registration Statement effective, in the case of a firm commitment underwritten
public offering, until each underwriter has completed the distribution of all
securities purchased by it and, in the case of any other offering, until the
earlier of the sale of all Registrable Shares covered thereby or 120 days after
the effective date thereof in the case of a registration statement on Form S-1
and two (2) years in the case of a registration statement on Form S-2 or S-3;

          (c)  as expeditiously as possible furnish to each selling Stockholder
such reasonable numbers of copies of the prospectus, including a preliminary
prospectus, in conformity with the requirements of the Securities Act, and such
other documents as the selling Stockholder may reasonably request in order to
facilitate the public sale or other disposition of the Registrable Shares owned
by the selling Stockholder; and

          (d)  as expeditiously as possible use its best efforts to register or
qualify the Registrable Shares covered by the Registration Statement under the
securities or Blue Sky laws of such states as the selling Stockholders shall
reasonably request, and do any and all other acts and things that may be
necessary or desirable to enable the selling Stockholders to consummate the
public sale or other disposition in such states of the Registrable Shares owned
by the selling Stockholder; provided, however, that the Company shall not be
required in connection with this paragraph (d) to qualify as a foreign
corporation or execute a general consent to service of process in any
jurisdiction.

If the Company has delivered preliminary or final prospectuses to the selling
Stockholders and after having done so the prospectus is amended to comply with
the requirements of the Securities Act, the Company shall promptly notify the
selling Stockholders and, if requested, the selling Stockholders shall
immediately cease making offers of Registrable Shares and return all
prospectuses to the Company. The Company shall promptly provide the selling
Stockholders with revised prospectuses and, following receipt of the revised
prospectuses, the selling Stockholders shall be free to resume making offers of
the Registrable Shares.

     5.   Allocation of Expenses. The Company will pay all Registration Expenses
of all registrations under this Agreement; provided, however, that if a
registration under Section 2 is withdrawn at the request of the Stockholders
requesting such registration (other than as a result of information concerning
the business or financial condition of the Company which is made known to the
Stockholders after the date on which such registration was requested) and if the
requesting Stockholders elect not to have such registration counted as a
registration requested under Section 2, the requesting Stockholders shall pay
the Registration Expenses of such



                                      -5-
<PAGE>   6

registration pro rata in accordance with the number of their Registrable Shares
included in such registration. For purposes of this Section 5, the term
"Registration Expenses" shall mean all expenses incurred by the Company in
complying with this Agreement, including, without limitation, all registration
and filing fees, exchange listing fees, printing expenses, fees and expenses of
counsel for the Company and up to $20,000 of the fees and expenses of one
counsel selected by the selling Stockholders to represent the selling
Stockholders, state Blue Sky fees and expenses, and the expense of any special
audits incident to or required by any such registration, but excluding
underwriting discounts, selling commissions and the fees and expenses of selling
Stockholders' own counsel (other than the counsel selected to represent all
selling Stockholders).

     6.   Indemnification and Contribution.

          (a)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, the Company will indemnify
and hold harmless the seller of such Registrable Shares, each underwriter of
such Registrable Shares, and each other person, if any, who controls such seller
or underwriter within the meaning of the Securities Act or the Exchange Act
against any losses, claims, damages or liabilities, joint or several, to which
such seller, underwriter or controlling person may become subject under the
Securities Act, the Exchange Act, state securities or Blue Sky laws or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement
under which such Registrable Shares were registered under the Securities Act,
any preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to such Registration Statement, or
arise out of or are based upon the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; and the Company will reimburse such seller, underwriter
and each such controlling person for any legal or any other expenses reasonably
incurred by such seller, underwriter or controlling person in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that the Company will not be liable in any such case if and
to the extent that any such loss, claim, damage or liability arises out of or is
based upon any untrue statement or omission made in such Registration Statement,
preliminary prospectus or final prospectus, or any such amendment or supplement,
in reliance upon and in conformity with information furnished to the Company, in
writing, by or on behalf of such seller, underwriter or controlling person
specifically for use in the preparation thereof.

          (b)  In the event of any registration of any of the Registrable Shares
under the Securities Act pursuant to this Agreement, each seller of Registrable
Shares, severally and not jointly, will indemnify and hold harmless the Company,
each of its directors and officers and each underwriter (if any) and each
person, if any, who controls the Company or any such underwriter within the
meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages or liabilities, joint or several, to which the Company, such directors
and officers, underwriter or controlling person may become subject under the
Securities Act, Exchange Act, state securities or Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement under which
such Registrable Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or



                                      -6-
<PAGE>   7

supplement to the Registration Statement, or arise out of or are based upon any
omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, if the
statement or omission was made in reliance upon and in conformity with
information relating to such seller furnished in writing to the Company by or on
behalf of such seller specifically for use in connection with the preparation of
such Registration Statement, prospectus, amendment or supplement; provided,
however, that the obligations of such Stockholders hereunder shall be limited to
an amount equal to the proceeds to each Stockholder of Registrable Shares sold
in connection with such registration.

          (c)  Each party entitled to indemnification under this Section 6 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom; provided, that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not be unreasonably
withheld); and, provided, further, that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 6. The Indemnified Party may participate in such
defense at such party's expense; provided, however, that the Indemnifying Party
shall pay such expense if representation of such Indemnified Party by the
counsel retained by the Indemnifying Party would be inappropriate due to actual
or potential differing interests between the Indemnified Party and any other
party represented by such counsel in such proceeding. No Indemnifying Party, in
the defense of any such claim or litigation shall, except with the consent of
each Indemnified Party, consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release from all
liability in respect of such claim or litigation, and no Indemnified Party shall
consent to entry of any judgment or settle such claim or litigation without the
prior written consent of the Indemnifying Party.

          (d)  In order to provide for just and equitable contribution to joint
liability under the Securities Act in any case in which either (i) any holder of
Registrable Shares exercising rights under this Agreement, or any controlling
person of any such holder, makes a claim for indemnification pursuant to this
Section 6 but it is judicially determined (by the entry of a final judgment or
decree by a court of competent jurisdiction and the expiration of time to appeal
or the denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 6 provides for
indemnification in such case, or (ii) contribution under the Securities Act may
be required on the part of any such selling Stockholder or any such controlling
person in circumstances for which indemnification is provided under this Section
6; then, in each such case, the Company and such Stockholder will contribute to
the aggregate losses, claims, damages or liabilities to which they may be
subject (after contribution from others) in such proportions so that such holder
is responsible for the portion represented by the percentage that the public
offering price of its Registrable Shares offered by the Registration Statement
bears to the public offering price of all securities offered by such
Registration Statement, and the Company is responsible for the remaining
portion; provided, however, that, in any such case, (A) no such holder will be
required to contribute any amount in excess of the proceeds to it of all
Registrable Shares sold by it pursuant to such



                                      -7-
<PAGE>   8

Registration Statement, and (B) no person or entity guilty of fraudulent
misrepresentation, within the meaning of Section 11(f) of the Securities Act,
shall be entitled to contribution from any person or entity who is not guilty of
such fraudulent misrepresentation.

     7.   Indemnification with Respect to Underwritten Offering. In the event
that Registrable Shares are sold pursuant to a Registration Statement in an
underwritten offering pursuant to Section 2, the Company agrees to enter into an
underwriting agreement containing customary representations and warranties with
respect to the business and operations of an issuer of the securities being
registered and customary covenants and agreements to be performed by such
issuer, including without limitation customary provisions with respect to
indemnification and contribution by the Company of the underwriters of such
offering.

     8.   Information by Holder. Each Stockholder including Registrable Shares
in any registration shall furnish to the Company such information regarding such
Stockholder and the distribution proposed by such Stockholder as the Company may
reasonably request in writing and as shall be required in connection with any
registration, qualification or compliance referred to in this Agreement.

     9.   "Stand-Off" Agreement. Each Stockholder, if requested by the Company
and the managing underwriter of an offering by the Company of Common Stock or
other securities of the Company pursuant to a Registration Statement, shall
agree not to sell publicly or otherwise transfer or dispose of any Registrable
Shares or other securities of the Company held by such Stockholder for a
specified period of time (not to exceed 180 days for an initial public offering
and 90 days for any other offering) following the effective date of such
Registration Statement; provided, that all officers and directors of the Company
enter into similar agreements.

     10.  Rule 144 Requirements. After the earliest of (i) the closing of the
sale of securities of the Company pursuant to a Registration Statement, (ii) the
registration by the Company of a class of securities under Section 12 of the
Exchange Act, or (iii) the issuance by the Company of an offering circular
pursuant to Regulation A under the Securities Act, the Company agrees to:

          (a)  comply with the requirements of Rule 144(c) under the Securities
Act with respect to current public information about the Company;

          (b)  use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements); and

          (c)  furnish to any holder of Registrable Shares upon request (i) a
written statement by the Company as to its compliance with the requirements of
said Rule 144(c), and the reporting requirements of the Securities Act and the
Exchange Act (at any time after it has become subject to such reporting
requirements), (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents of the Company as such
holder may reasonably request to avail itself of any similar rule or regulation
of the Commission allowing it to sell any such securities without registration.



                                      -8-

     11.  Mergers, Etc. The Company shall not, directly or indirectly, enter
into any merger, consolidation or reorganization in which the Company shall not
be the surviving corporation unless the proposed surviving corporation shall,
prior to such merger, consolidation or reorganization, agree in writing to
assume the obligations of the Company under this Agreement, and for that purpose
references hereunder to "Registrable Shares" shall be deemed to be references to
the securities which the Stockholders would be entitled to receive in exchange
for Registrable Shares under any such merger, consolidation or reorganization;
provided, however, that the provisions of this Section 11 shall not apply in the
event of any merger, consolidation or reorganization in which the Company is not
the surviving corporation if all Stockholders are entitled to receive in
exchange for their Registrable Shares consideration consisting solely of (i)
cash, (ii) securities of the acquiring corporation which may be immediately sold
to the public without registration under the Securities Act, or (iii) securities
of the acquiring corporation which the acquiring corporation has agreed to
register within 90 days of completion of the transaction for resale to the
public pursuant to the Securities Act.

     12.  Termination. All of the Company's obligations to register Registrable
Shares under this Agreement shall terminate on the tenth anniversary of this
Agreement.

     13.  Transferability of Rights. This Agreement, and the rights and
obligations of each Stockholder hereunder, may be assigned by such Stockholder
only after the closing of an initial public offering of the Company's Common
Stock.

     14.  General.

          (a)  Notices. All notices, requests, consents, and other

of or exceptions to any term, condition or provision of this Agreement, in any

counterparts, each of which shall be deemed to be an original, but all of which
shall be one and the same document.
