                                   THE COMPANY

     The Company was formed to design, develop and market high performance
general purpose parallel computer systems. Tera's Multithreaded Architecture
System ("MTA system") is designed to address a wide range of scientific and
engineering applications, such as simulation and visualization of complex
mechanical and biochemical systems, as well as emerging commercial applications,
such as database mining, information-on-demand and computer-aided design and
visualization. The Company believes that its MTA system represents a significant
breakthrough in high performance computing that will enable the Company to offer
systems with several times the price/performance of currently available
commercial high performance computer systems. Typical MTA system configurations
are expected to sell for between $5 million and $40 million. The Company
installed a single processor MTA system at the San Diego Supercomputer Center
("SDSC") in December 1997. In April 1998, the Company upgraded that system to a
two-processor MTA system, permitting the Company to recognize its first revenue
from system sales in the 1998 second fiscal quarter. The Company plans to
upgrade the MTA system at SDSC in stages to larger configurations as it receives
production printed circuit boards and other components from its vendors which
are then integrated into a commercially acceptable system. See "Risk Factors -
Manufacturing Risks; Reliance On and Capacity Of Third Party Sole Source
Suppliers."

     The Company was incorporated in Washington in December 1987. The Company's
principal executive offices are located at 2815 Eastlake Avenue East, Seattle,
Washington 98102-3027, and its telephone number is (206) 325-0800.

                                  RISK FACTORS

     In addition to the other information in this Prospectus, each prospective
investor should carefully consider the following factors in evaluating the
Company and its business before purchasing the securities offered hereby. No
investor should participate in the offering unless such investor can afford a
complete loss of the investor's investment. This Prospectus contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including but not
limited to those set forth in the following risk factors and elsewhere in this
Prospectus.

     Development Stage Status; History of Losses. The Company had an accumulated
loss from operations of approximately $52.2 million as of June 30, 1998, and has
transitioned from a development stage enterprise to a production company. The
Company has experienced net losses in each year of operations and expects to
incur substantial further losses as it commences production, and possibly
thereafter. In April 1998, the Company recognized its first revenue from the
sale of an MTA system; through June 30, 1998, the Company had not generated net
earnings. Although the Company has installed a two-processor MTA system at the
San Diego Supercomputer Center, it is dependent on third-party vendors to
provide production printed circuit boards and other necessary components in
order to enlarge that system. Whether the Company will achieve further revenue,
or any earnings, will depend upon a number of factors, including its ability to
manufacture and market the MTA system and to achieve broad market acceptance
thereof. In addition, profitability will depend on, among other things, the
level of revenue in any given period, the terms and conditions of sale or lease
for an MTA system, the system model or models sold, and the Company's expense
levels and manufacturing costs. There can be no assurance that the Company will
be successful in delivering and receiving payments for any additional production
MTA systems, or that it will be able to generate additional sales or achieve a
profitable level of operations in the future. See "Business-Markets and
Applications" and "Management's Discussion and Analysis of Financial

                                       -4-
<PAGE>
Condition and Results of Operations" in the Company's 1997 Annual Report on Form
10-K (the "1997 10-K").

     Development Status of the MTA System. The development of a new very high
performance computer system is a lengthy and technically challenging process and
requires a significant investment of capital and other resources. Several
companies in this market have experienced extreme financial difficulty in the
1990s, including Thinking Machines Corporation, Cray Computer Corporation,
Kendall Square Research Corporation and Supercomputer Systems, Inc. Since its
inception through June 30, 1998, the Company has expended approximately $70.0
million to design and develop the MTA system. The hardware development effort
has included design of integrated circuits, packaging and cooling systems and
at-speed testing equipment. The software development effort has included design
of compilers, an operating system and input-output software technology. The
Company only recently has begun to integrate multiple modules into commercially
configured systems.

     Modifications to the hardware components, software and the integrated
system still may be required. Development of system software is a difficult
process, and there can be no assurance that the Company will be able to meet all
of the technical challenges required to integrate and complete MTA systems that
satisfy both internal and commercially acceptable performance specifications.
Additional delays in completing the various hardware components or software, or
in integrating the full system, would materially and adversely affect the
Company's business and results of operations. Even if the Company is successful
in completing a commercially configured MTA system, there can be no assurance
that the Company's products will be commercially successful. See
"Business-Markets and Applications" and "-Competition" in the 1997 10-K.

     Manufacturing Risks; Reliance On and Capacity Of Third Party Sole Source
Suppliers. The Company has subcontracted the manufacture of substantially all of
its hardware components, including integrated circuits, printed circuit boards,
flex circuits and power supplies, on a sole or limited source basis to third
party suppliers, and there can be no assurance that such suppliers will be able
to manufacture the components to the Company's design specifications.
Manufacturing difficulties and limited yields, particularly of gallium arsenide
("GaAs") integrated circuits and advanced printed circuit boards and flex
circuits, could materially and adversely affect the Company's ability to
complete and deliver production models of the MTA system. The manufacture of
integrated circuits, and in particular the manufacture of GaAs integrated
circuits, is a difficult and complex process. Minute impurities, difficulties in
the fabrication process, defects in the masks used to print circuits on wafers
or other factors can cause a substantial percentage of wafers to be rejected or
numerous die on each wafer to be non-functional. The Company's suppliers may
experience problems in achieving acceptable manufacturing yields for these or
other reasons, resulting in substantial delays in the delivery of necessary
hardware components to the Company and unacceptably high prices for those
components, with a resulting loss of profitability or loss of competitiveness
for the Company's products. The Company has experienced such yield problems
already and these failures have forced the Company to redesign certain
components for manufacture by alternative suppliers which caused delays in the
fabrication of the Company's prototype and increased demands upon the Company's
financial resources. The Company also has experienced delays in receiving
packaged integrated circuits and printed circuit boards from its suppliers which
meet its design specifications. There can be no assurance that the Company's
efforts to obtain components in a timely manner that meet its design
specifications will be successful. Delays in obtaining such components adversely
affected the

                                       -5-
<PAGE>
Company's ability to deliver its first multi-processor MTA system to the San
Diego Supercomputer Center on schedule and may continue to hinder its ability to
satisfy future delivery schedules with the San Diego Supercomputer Center and
other potential customers.

     Moreover, the production capacity of the Company's integrated circuit and
printed circuit board suppliers is very limited and the availability of these
and other components will be a limiting factor on the number and size of the MTA
systems that may be sold in 1998, and thereafter, assuming the receipt of
additional purchase orders. Absent improved yields, increased production
capacity or a reallocation of such suppliers' output to meet the Company's
needs, the Company may be unable to obtain a sufficient quantity of suitable
components to meet future production and delivery schedules. In addition, some
of the Company's key suppliers are small companies with limited financial and
other resources, and consequently may be more likely to experience financial
difficulties than larger, well established companies. Any or all of the
Company's suppliers may make strategic changes in their product lines, which may
result in the delay or suspension of manufacture of the Company's components or
systems. In the event of a reduction or interruption of supply of the Company's
components, it could take the Company a considerable period of time to identify
and qualify alternative suppliers to redesign its products as necessary and
recommence manufacture. The Company's inability to obtain sufficient sole or
limited source components as required, or to develop alternative sources if and
as required in the future, could result in the Company finding itself without a
source of supply for its components; this could materially impair the Company's
ability to deliver its products, which would materially and adversely affect the
Company's business and results of operations.

     The Company's current contract with Unisys Corporation provided for
integrated circuit test and packaging services through June 1998. The Company
and Unisys are in the process of extending this agreement, although those
discussions have not been completed. If this agreement is not extended, the
Company would contract with another vendor for such packaging services or
perform such work internally. The inability of the Company to subcontract for
these services if its agreement with Unisys is not extended, or the Company's
inability to perform such services internally, would materially and adversely
affect the Company's business and results of operations.

     Future Capital Needs. During 1998, the Company's working capital needs will
depend primarily upon its personnel costs and the cost of inventory, as well as
manufacturing startup costs, inventory and receivable financing associated with
the production of MTA systems and research and development expenses related to
future implementations of the MTA systems. The Company has experienced delays in
the development of particular components of the MTA system that have increased
the need for working capital, and the Company could experience significant
additional delays in the manufacturing process that could further substantially
increase the Company's need for working capital. Personnel and operating costs
will be required to support ongoing research, development and engineering
efforts, development of a customer service organization, increases in its sales
and marketing efforts, and capital expenditures in lease of goods. Additionally,
the Company's administrative functions will increase in order to support its
engineering and sales efforts. If the Company were not to receive revenue from
the sale of MTA systems, it likely would be required to engage in additional
financings in order to continue current levels of business operations. The
Company may raise additional equity capital in 1998, even if revenues are
received from the sale of MTA systems when anticipated, in order to enhance its
financial position for future operations. There

                                       -6-
<PAGE>
can be no assurance that any additional financings will be available to the
Company when needed or, if available, will be available on satisfactory terms or
that any such financings will not be dilutive to the Company's shareholders. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations-Liquidity and Capital Resources" in the 1997 10-K.

     Marketing Risks; Government Funding and Regulation. The Company's initial
sales targets will be U.S. and foreign government agencies and research
laboratories, which constitute more than one-half of the market for very high
performance computer systems. The U.S. government historically has facilitated
the development of, and has constituted a market for, new and enhanced very high
performance computer systems. A change of policy by the U.S. government or
foreign governments that results in a reduction of, or delays in, funding of
certain high technology programs employing high performance computing could have
a major impact on the market for very high performance computer systems, and
would materially and adversely affect the Company's business, results of
operations and need for capital.

     Most of the Company's potential customers already own or lease very high
performance computer systems. Some of the Company's competitors may offer
trade-in allowances or substantial discounts to potential customers, and the
Company may not be able to match such sales incentives. The Company may be
required to provide discounts in order to make sales or be required to finance
the leasing of its products, which would result in a deferral of the Company's
receipt of cash for such systems. These developments could materially and
adversely affect the Company's business and results of operations.

     The U.S. government regulates the export of high performance computing
systems such as the anticipated MTA system. There can be no assurance that the
U.S. government will grant any necessary export licenses for the sale of MTA
systems to foreign buyers. The Company's prospects for growth will depend in
part on its ability to obtain export licenses for foreign sales, the delay or
denial of which could materially and adversely affect the Company's business and
results of operations.

     In order to expand its market beyond the very high performance scientific
market, and particularly beyond government agencies and research laboratories,
to engineering and other commercial markets, the Company must be able to attract
independent software vendors to port their software application programs so that
they will run on the MTA system. There can be no assurance that the Company will
be able to induce independent software vendors to port their applications, and
the failure to do so could materially and adversely affect the Company's
business and results of operations.

     Management of Growth; Dependence on Key Personnel. If the Company is
successful in manufacturing and marketing the MTA system, the Company believes
it could undergo a period of rapid growth that could place a significant strain
on its management, financial and other resources. The Company's ability to
manage its growth will require it to continue to improve its operational and
financial systems and to motivate and effectively manage its employees. If the
Company grows, it will have to implement new financial, budgeting, management
information and internal control systems. The success of the Company will depend
on the ability of management to implement effectively these changes and to
manage the Company's operations over the long term. The

                                       -7-
<PAGE>
Company's success also will depend in large part upon its ability to attract and
retain highly skilled technical personnel to provide technological depth and
support, to complete and enhance its first products and to develop new products.
In addition, marketing and sales personnel will be needed. Competition for
highly skilled management, technical, marketing and sales personnel is intense.
There can be no assurance that the Company will be successful in attracting and
retaining such personnel, and its failure to do so would materially and
adversely affect the Company's business and results of operations.

     The Company is dependent on Burton J. Smith, the Company's Chairman of the
Board and Chief Scientist, and James E. Rottsolk, the Company's Chief Executive
Officer, and the loss of services of either could have a material impact on the
ability of the Company to achieve its business objectives. The Company has key
man life insurance policies on the lives of Messrs. Smith and Rottsolk in the
amount of $2 million and $1 million, respectively. The Company has no employment
contracts with either Mr. Smith or Mr. Rottsolk or with any other employee.

     Quarterly Performance May Vary Significantly. In the event that the Company
is able to attain broad market acceptance of the MTA system, one or a few system
sales may account for a substantial percentage of the Company's quarterly and
annual revenue because of the anticipated high average sales price of the MTA
system models and the timing of purchase orders and product acceptances. Because
a number of the Company's prospective customers receive funding from the U.S. or
foreign governments, the timing of orders from such customers may be subject to
the appropriation and funding schedules of the relevant government agencies. The
timing of orders and shipments also could be affected by other events outside
the control of the Company, such as changes in levels of customer capital
spending, the introduction or announcement of competitive products, the
availability of components, currency fluctuations and international conflicts or
economic crises. Because of these factors, revenue, expenses, net income or loss
and cash flow are likely to fluctuate significantly from quarter to quarter.

     Rapid Technological Change and New Products. The market for the Company's
products is characterized by rapidly changing technology, accelerated product
obsolescence and rapidly changing industry standards. The Company's success will
depend upon its ability to complete development of the MTA system and to
introduce new products and features in a timely manner to meet evolving customer
requirements. There can be no assurance that the Company will be successful in
these efforts. The Company's business and results of operations will be
materially and adversely affected if the Company incurs delays in developing its
products or if such products do not gain broad market acceptance. In addition,
there can be no assurance that products or technologies developed by others will
not render the Company's products or technologies noncompetitive or obsolete.
See "Business-High Performance Computer Industry" and "-Competition" in the 1997
10-K.

     Competition. The Company's competitors can be divided into two general
categories: established companies that are well-known in the high performance
computer market and new entrants capitalizing on developments in parallel
processing and increased computer performance through networking.

     The high performance computer market is highly competitive and has been
dominated by Cray Research. Other participants in the market include IBM
Corporation and Japanese companies such as

                                       -8-
<PAGE>
Fujitsu, Ltd., Hitachi, Ltd., and NEC Corporation. Each of these competitors has
broader product lines and substantially greater research, engineering,
manufacturing, marketing and financial resources than the Company.

     A number of companies, including IBM, Silicon Graphics, Inc., Hitachi,
Ltd., Fujitsu Ltd., Sun Microsystems, Inc., and Hewlett-Packard Corporation,
through its subsidiary, Convex Computer, have developed or plan to develop
massively parallel systems for the high performance computer market. Although to
date this kind of system architecture has been limited in applicability and
difficult to program, a breakthrough in architecture or software technology
could change this situation. There can be no assurance that such a breakthrough
will not occur, and such an advance would materially and adversely affect the
Company's business and results of operations.

     There can be no assurance that the performance of the MTA system will be
competitive with the computer systems offered by the Company's competitors or
that the Company will be able to compete successfully over time against new
entrants or innovative competitors at the lower end of the market. Furthermore,
periodic announcements by the Company's competitors of new high performance
computer systems and price adjustments may materially and adversely affect the
Company's business and results of operations. See "Business-Technology" and
"-Competition" in the 1997 10-K.

     Proprietary Rights. The Company relies on a combination of copyright and
trade secret protection, non-disclosure agreements and licensing arrangements to
establish, protect and enforce its proprietary rights. Despite the Company's
efforts to safeguard and maintain its proprietary rights, there can be no
assurance that the Company will be successful in doing so or that the Company's
competitors will not independently develop or patent technologies that are
substantially equivalent or superior to the Company's technologies.

     Although the Company is not a party to any present litigation regarding
proprietary rights, there can be no assurance that third parties will not assert
intellectual property claims against the Company in the future. Such claims, if
proved, could materially and adversely affect the Company's business and results
of operations. In addition, although any such claims may ultimately prove to be
without merit, the necessary management attention to and legal costs associated
with litigation or other resolution of such claims could materially and
adversely affect the Company's business and results of operations. See
"Business-Intellectual Property" in the 1997 10-K.

     The laws of certain foreign countries do not protect intellectual property
rights to the same extent or in the same manner as do the laws of the United
States. Although the Company continues to implement protective measures and
intends to defend its proprietary rights vigorously, there can be no assurance
that these efforts will be successful.

     Shares Eligible for Future Sale. Sale of substantial amounts of the
Company's Common Stock in the public market or the prospect of such sales could
materially and adversely affect the market price of the Common Stock. As of July
23, 1998, the Company had outstanding 12,195,399 shares of Common Stock; 5,890
shares of Series A Convertible Preferred Stock ("Series A Stock") convertible
into shares of Common Stock, 6,000 shares of Series B Stock convertible into
shares of Common Stock, and privately placed warrants to purchase another
911,592 shares of Common Stock. Almost all of the Company's outstanding shares
of Common Stock may be sold without substantial

                                       -9-
<PAGE>
restrictions. In addition, as of such date, the Company had granted options
under its option plans to purchase an aggregate of 2,063,354 shares of Common
Stock. All of the shares purchased under the option plans are available for sale
in the public market, subject in some cases to volume and other limitations.

     Sales in the public market of substantial amounts of Common Stock,
including sales of Common Stock issuable upon conversion of the Series A Stock
and the Series B Stock and issuable upon exercise of the privately placed
warrants, or the perception that such sales could occur, could depress
prevailing market prices for the Common Stock. The existence of the Series A
Stock, the Series B Stock (including the Company's option to sell additional
shares of Series B Stock) and the privately placed warrants may prove to be a
hindrance to future equity financing by the Company. Further, the holders of
such warrants and options may exercise them at a time when the Company would
otherwise be able to obtain additional equity capital on terms more favorable to
the Company.

     Possible Volatility of Stock Price. The trading price of the Company's
Common Stock could be subject to significant fluctuations in response to
variations in quarterly operating results, changes in analysts' estimates,
announcements of technological innovations by the Company or its competitors,
general conditions in the very high performance computer industry and other
factors. In addition, the stock market is subject to price and volume
fluctuations that affect the market prices for companies in general, and small
capitalization, high technology companies in particular, and are often unrelated
to their operating performance.

     Possible Illiquidity of Trading Market. The Common Stock is quoted on the
Nasdaq National Market (the "National Market"). Nasdaq recently has implemented
more stringent maintenance requirements and significantly increased its
compliance enforcement efforts. If the Company should continue to experience
losses from operations, it may be unable to maintain the standards for continued
quotation on National Market, and the Common Stock could be subject to removal
therefrom. In the event that the Common Stock was delisted from the National
Market, the Company likely would apply for listing of its Common Stock on the
Nasdaq SmallCap Market or for quotation on the American Stock Exchange or a
regional stock exchange. Listing or quotation on such market or exchange could
reduce the liquidity of the market for the Common Stock. If the Common Stock was
not listed or quoted on such other market or exchange or if the Company failed
to apply for such listing or quotation, trading, if any, in the Common Stock
would be conducted in the over-the-counter market on an electronic bulletin
board established for unlisted securities, or in what are commonly referred to
as the "pink sheets." As a result, an investor would find it more difficult to
dispose of, or to obtain accurate quotations for the price of, the Common Stock.
In addition, such delisting from the Market and failure to obtain listing or
quotation on such other market or exchange would subject the Company's
securities to so-called "penny stock" rules that impose additional sales
practice and market-making requirements on broker-dealers who sell and/or make a
market in such securities. Consequently, removal from the Market and failure to
obtain listing or quotation on another market or exchange could affect the
ability or willingness of broker-dealers to sell and/or make a market in the
Common Stock and the ability of purchasers of the Common Stock to sell their
securities in the secondary market. In addition, if the market price of the
Common Stock falls to below $5.00 per share, the Company may become subject to
certain penny stock rules even if still quoted on the National Market. While
such penny stock rules should not affect the quotation of the Company's Common
Stock on the National Market, such rules may further limit the market liquidity
of the Common Stock and the ability of investors to sell the Common Stock in the
secondary market.

                                      -10-
<PAGE>
     No Anticipated Dividends. The Company has not previously paid any dividends
on its Common Stock and for the foreseeable future intends to continue its
policy of retaining any earnings to finance the development and expansion of its
business.

     Effect of Antitakeover Provisions. Certain provisions of the Company's
Restated Articles of Incorporation and Restated Bylaws and the laws of the State
of Washington could have the effect of making it more difficult for a third
party to acquire, or of discouraging a third party from attempting to acquire,
control of the Company. Such provisions could limit the price that certain
investors might be willing to pay in the future for shares of Common Stock. The
Company is authorized to issue preferred stock, without shareholder approval,
with rights senior to those of the Common Stock and to impose various procedural
and other requirements that could make it more difficult for shareholders to
effect certain corporate actions.

     Limitations on Liability and Indemnification Matters. As permitted by the
Washington Business Corporation Act, the Company has included in its Restated
Articles of Incorporation a provision to eliminate the personal liability of its
directors for monetary damages for breach or alleged breach of their fiduciary
duties as directors, subject to certain exceptions. In addition, the Bylaws of
the Company provide that the Company is required to indemnify its directors
under certain circumstances, including those in which indemnification would
otherwise be discretionary, and the Company is required to advance expenses to
its officers and directors as incurred in connection with proceedings against
them for which they may be indemnified.

                                  RECENT EVENTS

     The following summarizes significant events with respect to the Company
since March 31, 1998:

     1. Private Placement. On June 30, 1998, the Company raised $5,700,000, less
expenses, through the sale to the Selling Shareholders of 6,000 shares of Series
B Stock and the issuance of the Warrants. See "Selling Shareholders." Pursuant
to the terms of the Subscription Agreement, dated as of June 30, 1998 between
the Company and Advantage (the "Advantage Subscription Agreement"), the Company
may exercise an option to sell up to an additional 6,000 shares of Series B
Stock (the "Option Shares") at a purchase price of $950.00 per share, and to
issue up to an additional 100,000 Warrants (the "Additional Warrants"), to
Advantage at any time between September 30, 1998 and December 31, 1998, subject
to the satisfaction by the Company of certain conditions precedent to
Advantage's obligation to purchase the Option Shares and acquire the Additional
Warrants.

     2. Delivery of Two-Processor MTA System. On April 27, 1998, the San Diego
Supercomputer Center ("SDSC") accepted delivery of a two-processor MTA system,
permitting the Company to recognize its first revenue from system sales in the
1998 second fiscal quarter. At a supercomputer conference in Mannheim, Germany,
held in June 1998, SDSC researchers Allan Snavely and Jay Boisseau presented the
benchmark results in a paper entitled: "Cray T90 vs. Tera MTA: The Old Champ
Faces a New Challenger." The presentation can be found on SDSC's Website at
"www.sdsc.edu/~allans." Further information on the results can be found at
"www.hoise.com/primeur." The Company plans to upgrade the MTA system at SDSC in
stages to larger configurations as it receives production printed circuit boards
and other components from its vendors which are then integrated into a
commercially acceptable system. See "Risk Factors Manufacturing Risks; Reliance
On and Capacity Of Third Party Sole Source Suppliers."

     3. Use of Cash Resources. Since its incorporation through June 30, 1998,
the Company's principal sources of liquidity have been net proceeds from the
sale of equity of approximately $65.0 million and research funding of
approximately $19.0 million from the Defense Advanced Research Projects Agency.
As of June 30, 1998, the Company had approximately $8.95 million in cash and
cash equivalents, $480,000 in receivables, and no bank line of credit. Although
the Company believes its current cash resources, together with funds anticipated
from sales of MTA systems, to be sufficient to continue anticipated levels of
business operations through 1998, the Company may require further additional
working capital if sales of the MTA system, including additional deliveries to
SDSC, are substantially delayed. The Company may raise additional capital in
1998, through equity or debt financing transactions, even if revenues are
received from the sale of MTA systems when anticipated, in order to enhance its
financial position for future operations. Except with respect to the funds
payable to the Company upon exercise of its option under the Advantage
Subscription Agreement, there can be no assurance that any additional financings
will be available on acceptable terms when needed or that such financings will
not be dilutive to the Company's shareholders. See "Risk Factors - Future
Capital Needs" and "- Manufacturing Risks; Reliance On and Capacity of Third
Party Sole Source Suppliers."

                              SELLING SHAREHOLDERS

     On June 30, 1998, each of Advantage and Genesee Fund Limited - Portfolio B
acquired 3,000 shares of Series B Stock and 50,000 Warrants. Each share of
Series B Stock is convertible into the number of shares of Common Stock equal to
the quotient obtained by dividing (a) the sum of (i) $1,000, (ii) accrued and
unpaid dividends to the applicable conversion date and (iii) accrued and unpaid
interest on dividends in arrears to the applicable conversion date by (b) the
lower of (i) $14.52 or (ii) the lowest sale price (regular way) during the five
consecutive trading days ending the day immediately before the Company receives
a notice of conversion. The foregoing conversion price is subject to adjustment
in certain circumstances. The Warrants are exercisable at $15.00 per share,
which exercise price also is subject to adjustment in certain circumstances. The
Warrants contain provisions which permit "cashless exercises" pursuant to which
the holders may surrender to the Company a number of underlying shares of Common
Stock having a market value equal to the aggregate exercise price of the
Warrants being exercised, reducing the total number of shares to be issued by
the Company upon exercise.

         The following table sets forth certain information regarding the
beneficial ownership of the Common Stock by the Selling Shareholders and as
adjusted to give effect to the sale of the Shares offered hereby:

(1)  The number of shares of Common Stock shown as beneficially owned by the
     Selling Shareholders represents (i) the number of shares issuable upon
     conversion of the Series B Stock calculated using an assumed conversion
     price of $9.125 based on the conversion provisions of the Statement of
     Rights (which price is subject to fluctuation from time to time based on
     changes in the market price of the Common Stock); (ii) the number of shares
     issuable upon exercise of the Warrants; (iii) the number of shares issuable
     upon conversion of shares of Series A Stock issued by the Company to the
     Selling Shareholder in December 1997 which were outstanding as of July 27,
     1998 using an assumed conversion price of $9.125 based on the conversion
     provisions of the Statement of Rights and Preferences of the Series A Stock
     (which price is subject to fluctuation from time to time based on changes
     in the market price of the Common Stock); and (iv) the number of shares
     issuable upon the

                                      -14-
<PAGE>
     exercise of common stock purchase warrants issued by the Company to the
     Selling Shareholder in December 1997 (the "1997 Warrants") which were
     outstanding as of July 27, 1998.

     Pursuant to the terms of the Statement of Rights, the Statement of Rights
     and Preferences of the Series A Stock, the Warrants, and the 1997 Warrants,
     the Series B Stock and the Series A Stock are convertible by each holder
     thereof and dividends are payable in Common Stock, and the Warrants and the
     1997 Warrants are exercisable for Common Stock, only to the extent that the
     number of shares of Common Stock then beneficially owned by such holder and
     its related persons (not including shares underlying unconverted shares of
     Series B Stock and Series A Stock and unexercised Warrants and 1997
     Warrants) would not exceed 4.9% of the then outstanding shares of Common
     Stock as determined in accordance with Sections 13(d) and 16 of the
     Exchange Act. Accordingly, the number of shares of Common Stock set forth
     for the Selling Shareholder may exceed the actual number of shares of
     Common Stock that the Selling Shareholder could own beneficially at any
     given time through its ownership of the Series B Stock, the Series A Stock,
     the Warrants and the 1997 Warrants. The number of shares shown as
     beneficially owned by the Selling Shareholders assume that the Selling
     Shareholders will exercise the Warrants and the 1997 Warrants for cash. If
     the Selling Shareholders use the cashless exercise alternative, the actual
     number of shares of Common Stock issued will be fewer, depending on the
     market value of the underlying shares of Common Stock immediately prior to
     exercise.

(2)  Represents the number of shares issuable upon conversion of the Series B
     Stock and exercise of the Warrants calculated as described in note (1)
     above. Pursuant to Rule 416 under the Securities Act, the number of shares
     of Common Stock offered by the Selling Shareholders hereby and included in
     the Registration Statement of which this Prospectus is a part also includes
     such presently indeterminate number of additional shares as may be issued
     on (i) conversion of the Series B Stock and in payment of dividends thereon
     pursuant to the provisions of the Statement of Rights regarding
     determination of the applicable conversion price and the dividend
     calculation rate and (ii) exercise of the Warrants pursuant to the
     provisions thereof regarding adjustment for stock dividends, stock splits,
     reorganizations, reclassifications, and other extraordinary events.
     Accordingly, the actual number of shares of Common Stock issued or issuable
     upon the conversion of the Series B Stock and the payment of dividends
     thereon is subject to adjustment depending upon factors which cannot be
     predicted by the Company at this time, including, among others, the future
     market prices of the Common Stock and the payment of dividends on the
     Series B Stock in additional shares of Common Stock.

(3)  Assumes sale of (i) all of the shares of Common Stock issuable upon
     conversion of the Series A Stock and upon exercise of the 1997 Warrants
     that were registered pursuant to and included in that certain Registration
     Statement of Form S-3 (Registration No. 333-44137), and (ii) all of the
     Shares being offered hereby.

(4)  As of July 27, 1998, the Selling Shareholder held 3,872 shares of Series A
     Stock and 1997 Warrants exercisable for 87,500 shares of Common Stock.

                                      -15-

(5)  As of July 27, 1998, the Selling Shareholder held 2,018 shares of Series A
     Stock and 1997 Warrants exercisable for 37,500 shares of Common Stock.
</TABLE>


     The Selling Shareholders and their respective officers and directors have
not held any positions or office or had any other material relationship with the
Company or any of its affiliates within the past three years.

     In recognition of the fact that the Selling Shareholders may wish to be
legally permitted to sell their Shares when they deem appropriate, the Company
agreed with the Selling Shareholders to file with the Commission, under the
Securities Act, a Registration Statement on Form S-3, of which this Prospectus
forms a part, with respect to the resale of the Shares, and has agreed to
prepare and file such amendments and supplements to the Registration Statement
as may be necessary to keep the Registration Statement effective until the
Shares are no longer required to be registered for the sale thereof by the
Selling Shareholders.


                              PLAN OF DISTRIBUTION

     The Shares offered hereby by the Selling Shareholders may be sold from time
to time by the Selling Shareholders, or by pledgees, donees, transferees or
other successors in interest. Such sales may be made on one or more exchanges or
in the over-the-counter market (including the National Market), in privately
negotiated transactions, through the writing of options on the Shares, or
otherwise at market prices then prevailing or at prices related to the
then-current market price, at fixed prices that may be changed, or at negotiated
prices. The Shares may be sold to or through brokers or dealers, who may act as
agent or principal, or in direct transactions between the Selling Shareholders
and purchasers. In addition, the Selling Shareholders may, from time to time,
sell short the Common Stock, and in such instances, this Prospectus may be
delivered in connection with such short sale and the Shares offered hereby may
be used to cover such short sale.

     Transactions involving brokers or dealers may include, without limitation,
(a) ordinary brokerage transactions, (b) transactions in which the broker or
dealer solicits purchasers, (c) block trades in which the broker or dealer will
attempt to sell the Shares as agent but may position and resell a portion of the
block as principal to facilitate the transaction, and (d) purchases by a broker
or dealer as a principal and resale by such broker or dealer for its account. In
effecting sales, brokers and dealers engaged by the Selling Shareholders or the
purchasers of the Shares may arrange for other brokers or dealers to
participate. Such brokers or dealers may receive discounts, concessions or
commissions from the Selling Shareholders, the purchasers of the Shares for whom
such broker or dealer may act as agent or to whom they may sell as principal, or
both (which compensation as to a particular broker or dealer may be in excess of
customary commissions). The Selling

                                      -16-
<PAGE>
Shareholders and such brokers and dealers who act in connection with the sale of
Shares may be deemed to be "underwriters" within the meaning of the Securities
Act, and any commissions received by them and any profit on any resale of the
Shares as principal may be deemed to be underwriting discounts and commissions
under the Securities Act.

     Including and without limiting the foregoing, in connection with
distributions of the Common Stock, the Selling Shareholders may enter into
hedging transactions with brokers or dealers and the brokers or dealers may
engage in short sales of the Common Stock in the course of hedging the positions
they assume with the Selling Shareholders. The Selling Shareholders also may
enter into option or other transactions with brokers or dealers that involve the
delivery of the Common Stock to the brokers or dealers, who may then resell or
otherwise transfer such Common Stock. The Selling Shareholders also may loan or
pledge the Common Stock to a broker or dealer and the broker or dealer may sell
the Common Stock so loaned or upon default may sell or otherwise transfer the
pledged Common Stock.

     The Company is bearing all costs relating to the registration of the
Shares. Any commissions, discounts or other fees payable to brokers or dealers
in connection with any sale of the Shares will be borne by the Selling
Shareholders, the purchasers participating in such transaction, or both. None of
the proceeds from the sale of the Shares by the Selling Shareholders will be
received by the Company. The Company and the Selling Shareholders each have
agreed to indemnify the other against certain liabilities, including liabilities
arising under the Securities Act, that relate to statements or omissions in the
Registration Statement of which this Prospectus forms a part.

     Any Shares covered by this Prospectus which qualify for sale pursuant to
Rule 144 under the Securities Act may be sold under such Rule rather pursuant to
this Prospectus.


                                     EXPERTS

     The financial statements of the Company as of December 31, 1996 and 1997
and for each of the two years in the period ended December 31, 1997,
incorporated by reference into this Prospectus, have been audited by Deloitte &
Touche LLP, independent auditors, as stated in their reports with respect
thereto. Such financial statements have been so incorporated in reliance on the
reports of such firm given upon their authority as experts in accounting and
auditing.

                   LIMITATION OF LIABILITY AND INDEMNIFICATION

     The Company's Restated Articles of Incorporation provide that, to the
fullest extent permitted by the Washington Business Corporation Act, the
Company's directors will not be liable for monetary damages to the Company or
its shareholders, excluding, however, liability for acts or omissions involving
intentional misconduct or knowing violations of law, illegal distributions or
transactions from which the director receives benefits to which the director is
not legally entitled. The Company's Restated Bylaws provide that the Company
will indemnify its directors and, by action of the Board of Directors, may
indemnify its officers, employees and other agents of the Company to the fullest
extent permitted by applicable law, except for any legal proceeding that is
initiated by such directors, officers, employees or agents without authorization
of the Board of Directors. See "Risk Factors Limitations on Liability and
Indemnification Matters."

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the foregoing provisions, or otherwise, the Company has been advised
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution.

     All expenses in connection with the issuance and distribution of the
securities being registered will be paid by the Company. The following is an
itemized statement of these expenses (all amounts are estimated except for the
SEC and Nasdaq listing fees):

     SEC Registration fee.........................................  $   2,100

     Nasdaq listing fee...........................................  $   7,500

     Legal fees...................................................  $  10,000

     Accountant's Fees............................................  $   1,000

     Printing Fees................................................  $     500

     Miscellaneous................................................  $   1,400
                                                                    ---------

     Total........................................................  $  22,500


Item 15. Indemnification of Officers and Directors.

     Article XII of the Company's Restated Articles of Incorporation and Section
11 of the Company's Restated Bylaws require indemnification of directors,
officers, employees and agents of the Company to the fullest extent permitted by
the Washington Business Corporation Act (the "Act"). Sections 23B.08.500 through
23B.08.000 of the Act authorize a court to award, or a corporation's board of
directors to grant, indemnification to directors and officers on terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities arising under the Securities Act.

     Section 23B.08.320 of the Act authorizes a corporation to limit a
director's liability to the corporation or its shareholders for monetary damages
for acts or omissions as a director, except in certain circumstances involving
intentional misconduct, self-dealing or illegal corporate loans or
distributions, or any transaction from which the director personally receives a
benefit in money, property or services to which the director is not legally
entitled. Article XI of the Company's Restated Articles of Incorporation
contains provisions implementing, to the fullest extent permitted by Washington
law, such limitations on a director's liability to the Company and its
shareholders.

(1)  Incorporated by reference to Amendment No. 3 to the Company's Registration
     Statement on Form SB-2, Registration No. 33-95460-LA, filed with the
     Commission on September 22, 1995

Item 17.  Undertakings.

     (a)  The undersigned registrant hereby undertakes:

          (1)  To file, during any period in which offers or sales are being
               made, a post-effective amendment to this Registration Statement

               (i)    To include any prospectus required by Section 10(a)(3) of
                      the Securities Act of 1933, as amended;

                                      -20-
<PAGE>
               (ii)   To reflect in the prospectus any facts or events arising
                      after the effective date of this Registration Statement
                      (or the most recent post-effective amendment thereof)
                      that, individually or in the aggregate, represent a
                      fundamental change in the information set forth in this
                      Registration Statement; and

               (iii)  To include any additional or changed material information
                      with respect to the plan of distribution;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
               not apply if the information required to be included in a
               post-effective amendment by those paragraphs is incorporated by
               reference from periodic reports filed by the registrant pursuant
               to Section 13 or Section 15(d) of the Exchange Act.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each post-effective amendment shall be deemed to
               be a new registration statement relating to the securities
               offered therein, and the offering of such securities at that time
               shall be deemed to be the initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered that remain
               unsold at the termination of the offering.

     (b)  The undersigned registrant hereby undertakes that, for purposes of
          determining any liability under the Securities Act of 1933, each
          filing of the registrant's annual report pursuant to Section 13(a) or
          Section 15(d) of the Securities Exchange Act of 1934 that is
          incorporated by reference in the registration statement 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.

     (c)  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 foregoing provisions, or
          otherwise, the registrant has been advised that in the opinion of the
          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, the registrant will, unless in the
          opinion of its counsel the matter has been settled by controlling
          precedent, submit to a court of appropriate jurisdiction the question,
          whether such indemnification by it is against public policy as
          expressed in the Securities Act and will be governed by the final
          adjudication of such issue.

                              TERA COMPUTER COMPANY


                                  12,000 Shares
              Series B Convertible Preferred Stock, $.01 Par Value

                        Stated Value $1,000.00 Per Share

                       Statement of Rights and Preferences


     Series B Convertible Preferred Stock. The rights, preferences, privileges,
and limitations granted to and imposed on the Series B Convertible Preferred
Stock (the "Series B Convertible Preferred Stock") of Tera Computer Company (the
"Corporation"), which series shall consist of 12,000 shares, are as set forth
below. Subject to the terms of the Series B Convertible Preferred Stock set
forth herein, the following rights, preferences, privileges, and limitations are
subject to the designation, description, and terms of one or more subsequent
series of Preferred Stock by the Board of Directors of the Corporation, pursuant
to authority granted by the Restated Articles of Incorporation.

     Section 1. Designation and Amount.

     The shares of such series shall be designated as "Series B Convertible
Preferred Stock," and the number of shares constituting the Series B Convertible
Preferred Stock shall be 12,000, and shall not be subject to increase.

     Section 2. Dividends and Distributions.

          (a) The holders of outstanding shares of Series B Convertible
Preferred Stock shall be entitled to receive, when, as, and if declared by the
Board of Directors of the Corporation (the "Board of Directors" or the "Board")
out of funds legally available for such purpose, dividends at the rate of $50.00
per annum per share, and no more, which shall be fully cumulative, shall accrue
without interest (except as otherwise provided herein as to dividends in
arrears) from the date of original issuance and shall be payable quarterly on
January 1, April 1, July 1, and October 1 of each year, commencing October 1,
1998 (except that if any such date is a Saturday, Sunday, or legal holiday, then
such dividend shall be payable on the next succeeding day that is not a
Saturday, Sunday, or legal holiday) to holders of record as they appear on the
stock books of the Corporation on such record dates, not more than 20 nor less
than 10 days preceding the payment dates for such dividends, as shall be fixed
by the Board. Dividends on the Series B Convertible Preferred Stock shall be

                                       -1-
<PAGE>
paid in cash or, subject to the limitations in Section 2(b) hereof, shares of
Common Stock of the Corporation or any combination of cash and shares of Common
Stock, at the option of the Corporation as hereinafter provided. The amount of
the dividends payable per share of Series B Convertible Preferred Stock for each
quarterly dividend period shall be computed by dividing the annual dividend
amount by four. The amount of dividends payable for the initial dividend period
and any period shorter than a full quarterly dividend period shall be computed
on the basis of a 360-day year of twelve 30-day months. Dividends not paid on a
payment date, whether or not such dividends have been declared, will bear
interest at the rate of 12% per annum until paid. No dividends or other
distributions, other than dividends payable solely in shares of Common Stock or
other capital stock of the Corporation ranking junior as to dividends to the
Series B Convertible Preferred Stock (collectively, the "Junior Dividend
Stock"), shall be paid or set apart for payment on any shares of Junior Dividend
Stock, and no purchase, redemption, or other acquisition shall be made by the
Corporation of any shares of Junior Dividend Stock unless and until all accrued
and unpaid dividends on the Series B Convertible Preferred Stock and interest on
dividends in arrears at the rate specified herein shall have been paid or
declared and set apart for payment.

     If at any time any dividend on any capital stock of the Corporation ranking
senior as to dividends to the Series B Convertible Preferred Stock (the "Senior
Dividend Stock") shall be in default, in whole or in part, no dividend shall be
paid or declared and set apart for payment on the Series B Convertible Preferred
Stock unless and until all accrued and unpaid dividends with respect to the
Senior Dividend Stock, including the full dividends for the then current
dividend period, shall have been paid or declared and set apart for payment,
without interest. No full dividends shall be paid or declared and set apart for
payment on any class or series or the Corporation's capital stock ranking, as to
dividends, on a parity with the Series B Convertible Preferred Stock (the
"Parity Dividend Stock") for any period unless all accrued but unpaid dividends
(and interest on dividends in arrears at the rate specified herein) have been,
or contemporaneously are, paid or declared and set apart for such payment on the
Series B Convertible Preferred Stock. No full dividends shall be paid or
declared and set apart for payment on the Series B Convertible Preferred Stock
for any period unless all accrued but unpaid dividends have been, or
contemporaneously are, paid or declared and set apart for payment on the Parity
Dividend Stock for all dividend periods terminating on or prior to the date of
payment of such full dividends. When dividends are not paid in full upon the
Series B Convertible Preferred Stock and the Parity Dividend Stock, all
dividends paid or declared and set apart for payment upon shares of Series B
Convertible Preferred Stock (and interest on dividends in arrears at the rate
specified herein) and the Parity Dividend Stock shall be paid or declared and
set apart for payment pro rata, so that the amount of dividends paid or declared
and set apart for payment per share on the Series B Convertible Preferred Stock
and the Parity Dividend Stock shall in all cases bear to each other the same
ratio that accrued and unpaid dividends per share on the shares of Series B
Convertible Preferred Stock and the Parity Dividend Stock bear to each other.

                                       -2-
<PAGE>
     Any references to "distribution" contained in this Section 2 shall not be
deemed to include any stock dividend or distributions made in connection with
any liquidation, dissolution, or winding up of the Corporation, whether
voluntary or involuntary.

          (b) If the Corporation elects in the exercise of its sole discretion
to issue shares of Common Stock in payment of dividends on the Series B
Convertible Preferred Stock, the Corporation shall issue and dispatch, or cause
to be issued and dispatched, by the third trading day after such dividend
payment date to each holder of such shares a certificate representing the number
of whole shares of Common Stock arrived at by dividing the per share Computed
Price (as defined below) of such shares of Common Stock into the total amount of
cash dividends such holder would be entitled to receive if the aggregate
dividends on the Series B Convertible Preferred Stock held by such holder which
are being paid in shares of Common Stock were being paid in cash; provided,
however, that if certificates representing shares of Common Stock are issued and
dispatched to holders of Series B Convertible Preferred Stock subsequent to the
fifth trading day after a dividend payment date, the percentage used to
calculate the Computed Price will be reduced by one for each trading day after
the third trading day following such dividend payment date to the date of
dispatch of shares of Common Stock. No fractional shares of Common Stock shall
be issued in payment of dividends. In lieu thereof, the Corporation shall pay
cash in an amount equal to the product of (x) the arithmetic average of the
Closing Price (as defined below) of the Common Stock for the Measurement Period
(as defined in Section 7(b)) applicable to such dividend payment date and (y)
the fraction of a share of Common Stock that would otherwise be issuable by the
Corporation. The Corporation shall not exercise its right to issue shares of
Common Stock in payment of dividends on Series B Convertible Preferred Stock if:

          (i)  the number of shares of Common Stock at the time authorized,
               unissued and unreserved for all purposes is insufficient to pay
               the portion of such dividends to be paid in shares of Common
               Stock;

          (ii) the issuance or delivery of shares of Common Stock as a dividend
               payment would require registration with or approval of any
               governmental authority under any law or regulation, and such
               registration or approval has not been effected or obtained;

          (iii) the shares of Common Stock to be issued as a dividend payment
               have not been authorized for listing, upon official notice of
               issuance, on any securities exchange or market on which the
               Common Stock is then listed, or have not been approved for
               quotation if the Common Stock is traded in the over-the-counter
               market;

          (iv) the Computed Price (determined without regard to the proviso to
               the definition thereof) is less than the par value of one share
               of Common Stock;

          (v)  the shares of Common Stock (A) cannot be sold or transferred
               without restriction by unaffiliated holders who receive such
               shares of Common Stock as a dividend payment or (B) are not then
               listed on a national securities exchange, on the Nasdaq National
               Market or the Nasdaq SmallCap Market (collectively referred to
               herein as the "Nasdaq");

          (vi) the issuance of shares of Common Stock in payment of dividends on
               Series B Convertible Preferred Stock held by any Restricted
               Person (as defined in Section 7(a)) would result in any

               sentence of Section 7(a) hereof; or

          (vii) an Optional Redemption Event (as defined in Section 8(a)) shall
               have occurred and any holder shall be entitled to exercise
               optional redemption rights under Section 8 hereof by reason of
               such Optional Redemption Event.

     Shares of Common Stock issued in payment of dividends on Series B
Convertible Preferred Stock pursuant to this Section shall be, and for all
purposes shall be deemed to be, validly issued, fully paid and nonassessable
shares of Common Stock of the Corporation; the issuance and delivery thereof is
hereby authorized; and the dispatch thereof will be, and for all purposes shall
be deemed to be, payment in full of the cumulative dividends to which holders
are entitled on the applicable dividend payment date.

     "Closing Price" of any security on any date shall mean the last sale price
(regular way) of such security on such date on the principal securities exchange
or other market on which such security is listed for trading which constitutes
the principal securities market for such security, as reported by such exchange
or other market.

     "Computed Price" of one share of Common Stock on any date means the product
of (1) the Conversion Percentage (as defined in Section 7(b)) applicable on such
date and (2) the lowest Market Price (as defined in Section 7(b)) of the Common
Stock during the Measurement Period with respect to the applicable dividend
payment date; provided, however, that, notwithstanding the foregoing, in no
event shall the Computed Price be less than $.01 per share or greater than the
Ceiling Price (as defined in Section 7(b)) (subject to equitable adjustments for
stock splits, stock dividends, combinations, recapitalizations,

                                       -4-

reclassifications and similar events occurring on or after the date of filing of
this Statement of Rights and Preferences with the Secretary of State of the
State of Washington).

          (c) Neither the Corporation nor any subsidiary of the Corporation
shall redeem, repurchase or otherwise acquire in any one transaction or series
of related transactions any shares of Common Stock, Junior Dividend Stock or
Junior Liquidation Stock (as defined in Section 3) if the number of shares so
repurchased, redeemed or otherwise acquired in such transaction or series of
related transactions is more than either (x) 5.0% of the number of shares of
Common Stock, Junior Dividend Stock or Junior Liquidation Stock, as the case may
be, outstanding immediately prior to such transaction or series of related
transactions or (y) 1% of the number of shares of Common Stock, Junior Dividend
Stock or Junior Liquidation Stock, as the case may be, outstanding immediately
prior to such transaction or series of related transactions if such transaction
or series of related transactions is with any one person or group of affiliated
persons, unless the Corporation or such subsidiary offers to purchase for cash
from each holder of shares of Series B Convertible Preferred Stock at the time
of such redemption, repurchase or acquisition the same percentage of such
holder's shares of Series B Convertible Preferred Stock as the percentage of the
number of outstanding shares of Common Stock, Junior Dividend Stock or Junior
Liquidation Stock, as the case may be, to be so redeemed, repurchased or
acquired at a purchase price per share of Series B Convertible Preferred Stock
equal to the greater of (i) the sum of (a) the product obtained by multiplying
(1) the sum of (A) $1,000.00 plus (B) the amount of accrued but unpaid dividends
on such share of Series B Convertible Preferred Stock to the date of repurchase
pursuant to this Section 2(c) times (2) 115% plus (b) an amount equal to the
accrued and unpaid interest on dividends in arrears (determined as provided in
Section 2) through the date of purchase pursuant to this Section 2(c), or (ii)
an amount equal to the product of (x) the number of shares of Common Stock which
would, but for the purchase pursuant to this Section 2(c), be issuable on
conversion in accordance with Section 7(a) of one share of Series B Convertible
Preferred Stock and any accrued and unpaid dividends thereon and any accrued and
unpaid interest on dividends thereon in arrears if a Conversion Notice were
given by the holder of such share of Series B Convertible Preferred Stock on the
date of purchase pursuant to this Section 2(c) (determined without regard to any
limitation on conversion contained in Section 7(a)) and (y) the arithmetic
average of the Closing Price (as defined in Section 2(b)) of the Common Stock
for the Measurement Period with respect to the date of purchase pursuant to this
Section 2(c).

          (d) Neither the Corporation nor any subsidiary of the Corporation
shall (1) make any tender offer or exchange offer (a "Tender Offer") for
outstanding shares of Common Stock, unless the Corporation contemporaneously
therewith makes an offer, or (2) enter into an agreement regarding a Tender
Offer for outstanding shares of Common Stock by any person other than the
Corporation or any subsidiary of the Corporation, unless such person agrees with
the Corporation to make an offer, in either such case to each holder of
outstanding shares of Series B Convertible Preferred Stock to purchase for cash
at the time of

                                       -5-
<PAGE>
purchase in such Tender Offer the same percentage of shares of Series B
Convertible Preferred Stock held by such holder as the percentage of outstanding
shares of Common Stock offered to be purchased in such Tender Offer at a price
per share of Series B Convertible Preferred Stock equal to the greater of (i)
the sum of (a) the sum of (1) $1,000.00, (2) an amount equal to the accrued but
unpaid dividends on such share of Series B Convertible Preferred Stock, and (3)
an amount equal to the accrued and unpaid interest on dividends in arrears

in the immediately preceding clause (a) times (y) the quotient (expressed as a
percentage) obtained by dividing (A) the amount determined by subtracting from
100 percent the Conversion Percentage in effect on the date of purchase pursuant
to this Section 2(d) by (B) the Conversion Percentage in effect on the date of
purchase pursuant to this Section 2(d), or (ii) an amount equal to the product
of (x) the number of shares of Common Stock which would, but for the purchase

dividends thereon in arrears if a Conversion Notice were given by the holder of
such share of Series B Convertible Preferred Stock on the date of purchase
pursuant to this Section 2(d) (determined without regard to any limitation on
conversion contained in Section 7(a)) and (y) the price per share of Common
Stock offered in such Tender Offer. This provision shall not apply to any tender
offer, exchange offer or redemption of any of the Corporation's outstanding
redeemable common stock purchase warrants.

     Section 3. Liquidation Preference.

     In the event of a liquidation, dissolution, or winding up of the
Corporation, whether voluntary or involuntary, the holders of Series B
Convertible Preferred Stock shall be entitled to receive out of the assets of
the Corporation, whether such assets constitute stated capital or surplus of any
nature, an amount per share of Series B Convertible Preferred Stock equal to the
sum of (i) all dividends accrued and unpaid thereon to the date of final
distribution to such holders, (ii) accrued and unpaid interest on dividends in
arrears (computed in accordance with Section 2(a)) to the date of distribution,
and (iii) $1,000.00 (collectively, "the Liquidation Preference"), and no more,
before any payment shall be made or any assets distributed to the holders of
Common Stock or any other class or series of the Corporation's capital stock
ranking junior as to liquidation rights to the Series B Convertible Preferred
Stock (collectively, the "Junior Liquidation Stock"); provided, however, that
such rights shall accrue to the holders of Series B Convertible Preferred Stock
only in the event that the Corporation's payments with respect to the
liquidation preference of the holders of capital stock of the Corporation
ranking senior as to liquidation rights to the Series B Convertible Preferred
Stock (the "Senior Liquidation Stock") are fully met. After the liquidation
preferences of the Senior Liquidation Stock are fully met, the entire assets of
the Corporation available for distribution shall be distributed ratably among
the holders of the Series B

                                       -6-
<PAGE>
Convertible Preferred Stock and any other class or series of the Corporation's
capital stock having parity as to liquidation rights with the Series B
Convertible Preferred Stock (the "Parity Liquidation Stock") in proportion to
the respective preferential amounts to which each is entitled (but only to the
extent of such preferential amounts). After payment in full of the liquidation
price of the shares of the Series B Convertible Preferred Stock and the Parity
Liquidation Stock, the holders of such shares shall not be entitled to any
further participation in any distribution of assets by the Corporation. Neither
a consolidation or merger of the Corporation with another corporation nor a sale
or transfer of all or part of the Corporation's assets for cash, securities, or
other property in and of itself will be considered a liquidation, dissolution,
or winding up of the Corporation. So long as any shares of Series B Convertible
Preferred Stock are outstanding, the Corporation shall, whenever appropriate,
cause its books, records and financial statements to reflect the Liquidation
Preference as a valid obligation of the Corporation payable prior to any payment
or distribution of assets to any holders of Junior Liquidation Stock upon any
liquidation, dissolution, or winding up of the Corporation.

     Section 4. Mandatory Redemption.

          (a) Mandatory Redemption Based on Maximum Share Amount.

               (1) Notwithstanding any other provision herein, unless the
Shareholder Approval shall have been obtained from the shareholders of the
Corporation or waived by the Nasdaq, the Corporation shall not be required to
issue upon conversion of shares of Series B Convertible Preferred Stock pursuant
to Section 7 more than 2,437,500 shares of Common Stock, or such greater number
as permitted by the rules of the Nasdaq (such amount to be subject to equitable
adjustment from time to time for stock splits, stock dividends, combinations,
capital reorganizations and similar events relating to the Common Stock
occurring after the date of filing this Statement of Rights and Preferences with
the Secretary of State of the State of Washington) (the "Maximum Share Amount"),
less the aggregate number of shares of Common Stock issued by the Corporation
pursuant to Section 2 as dividends on the Series B Convertible Preferred Stock.
The Maximum Share Amount shall be allocated among the shares of Series B
Convertible Preferred Stock at the time of initial issuance thereof pro rata
based on the total number of authorized shares of Series B Convertible Preferred
Stock provided in Section 1. Each certificate for shares of Series B Convertible
Preferred Stock initially issued shall bear a notation as to the number of
shares constituting the portion of the Maximum Share Amount allocated to the
shares of Series B Convertible Preferred Stock represented by such certificate
for purposes of conversion thereof. The Corporation shall maintain records which
show the number of shares of Common Stock issued by the Corporation pursuant to
Section 2 as dividends on the shares of Series B Convertible Preferred Stock
represented by each certificate, which records shall be controlling in the
absence of manifest error. Upon surrender of any certificate for shares of
Series B Convertible Preferred Stock for transfer or re-registration thereof
(or, at

                                       -7-
<PAGE>
the option of the holder, for conversion pursuant to Section 7(a) of less than
all of the shares of Series B Convertible Preferred Stock represented thereby),
the Corporation shall make a notation on the new certificate issued upon such
transfer or re-registration or evidencing such unconverted shares, as the case
may be, as to the remaining number of shares of Common Stock from the Maximum
Share Amount remaining available for conversion of the shares of Series B
Convertible Preferred Stock evidenced by such new certificate (including,
without limitation, by taking into account the number of shares of Common Stock
issued by the Corporation pursuant to Section 2 as a dividend on the shares of
Series B Convertible Preferred Stock represented by the certificate so
surrendered and not previously reflected on the certificate so surrendered, as
shown on the records maintained by the Corporation). If any certificate for
shares of Series B Convertible Preferred Stock is surrendered for split-up into
two or more certificates representing an aggregate number of shares of Series B
Convertible Preferred Stock equal to the number of shares of Series B
Convertible Preferred Stock represented by the certificate so surrendered (as
reduced by any contemporaneous conversion of shares of Series B Convertible
Preferred Stock represented by the certificate so surrendered), each certificate
issued on such split-up shall bear a notation of the portion of the Maximum
Share Amount allocated thereto determined by pro rata allocation from among the
remaining portion of the Maximum Share Amount allocated to the certificate so
surrendered. If any shares of Series B Convertible Preferred Stock represented
by a single certificate are converted in full pursuant to Section 7, all of the
portion of the Maximum Share Amount allocated to such shares of Series B
Convertible Preferred Stock which remains unissued after such conversion shall
be re-allocated pro rata to the outstanding shares of Series B Convertible
Preferred Stock held of record by the holder of record at the close of business
on the date of such conversion of the shares of Series B Convertible Preferred
Stock so converted, and if there shall be no other shares of Series B
Convertible Preferred Stock held of record by such holder at the close of
business on such date, then such portion of the Maximum Share Amount shall be
allocated pro rata among the shares of Series B Convertible Preferred Stock
outstanding on such date. If the Second Issuance Date does not occur or if less
than 6,000 shares of Series B Convertible Preferred Stock are issued on the
Second Issuance Date, on the earlier of the Second Issuance Date or the date
when the Second Issuance Date is no longer permitted to occur under the terms of
the Subscription Agreement, the portion of the Maximum Share Amount initially
allocated to such unissued shares of Series B Convertible Preferred Stock (equal
to 12,000 less the sum of (i) 6,000 plus (ii) the number of such shares issued
on the Second Issuance Date) shall be re-allocated pro rata among the shares of
Series B Convertible Preferred Stock outstanding on such date.

               (2) The Corporation shall promptly, but in no event later than
five business days after the occurrence, give notice to each holder (by
facsimile to such number as such holder has specified in writing to the
Corporation for such purposes or, if such holder shall not have specified any
such number, by overnight courier or first class mail, postage prepaid, at such
holder's address as the same appears on the stock books of the Corporation) and
any holder may at any time after the occurrence give notice to the

                                      -8-
<PAGE>
Corporation, in either case, if on any ten trading days within any period of 20
consecutive trading days the Corporation would not have been required to convert
shares of Series B Convertible Preferred Stock of such holder in accordance with
Section 7(a) as a consequence of the limitations set forth in Section 4(a)(1)
had all outstanding shares of Series B Convertible Preferred Stock held by such
holder been converted into Common Stock on each such day, determined without
regard to the limitation, if any, on such holder contained in the proviso to the
second sentence of Section 7(a) (any such notice, whether given by the
Corporation or a holder, an "Inconvertibility Notice"). If the Corporation shall
have given or been required to give any Inconvertibility Notice, or if a holder
shall have given any Inconvertibility Notice, then within ten business days
after such Inconvertibility Notice is given or was required to be given, the
holder receiving or giving, as the case may be, the Inconvertibility Notice
shall have the right by written notice to the Corporation (which written notice
may be contained in the Inconvertibility Notice given by the holder) to direct
the Corporation to redeem the portion of such holder's outstanding shares of
Series B Convertible Preferred Stock (which, if applicable, shall be all of such
holder's outstanding shares of Series B Convertible Preferred Stock if all of
such shares are so inconvertible) as shall not, on the business day prior to the
date of such redemption, be convertible into shares of Common Stock by reason of
the limitations set forth in Section 4(a)(1) (determined without regard to the
limitation, if any, on such holder contained in the proviso to the second
sentence of Section 7(a)), within ten business days after such holder so directs
the Corporation, at a price per share equal to the Share Limitation Redemption
Price (as defined in Section 4(a)(6)), unless prior to the date the Corporation
is required to redeem such shares of Series B Convertible Preferred Stock the
Corporation delivers a written notice to the holder otherwise so entitled to
redemption of such shares of Series B Convertible Preferred Stock stating that
the Corporation has elected to seek the Shareholder Approval (a "Shareholder
Approval Notice"). If a holder directs the Corporation to redeem outstanding
shares of Series B Convertible Preferred Stock and, prior to the date the
Corporation is required to redeem such shares of Series B Convertible Preferred
Stock, the Corporation would have been able, within the limitations set forth in
Section 4(a)(1), to convert all of such holder's outstanding shares of Series B
Convertible Preferred Stock (determined without regard to the limitation, if
any, on such holder contained in the proviso to the second sentence of Section
7(a)) on any ten trading days within any period of 20 consecutive trading days
commencing after the period of 20 consecutive trading days which gave rise to
the applicable Inconvertibility Notice from the Corporation or such holder of
shares of Series B Convertible Preferred Stock, as the case may be, had all of
such holder's outstanding shares of Series B Convertible Preferred Stock been
surrendered for conversion into Common Stock on each of such ten trading days
within such 20 trading day period, then the Corporation shall not be required to
redeem any shares of Series B Convertible Preferred Stock by reason of such
Inconvertibility Notice.

<PAGE>
               (3) If the Corporation shall have given a Shareholder Approval
Notice, then the Corporation thereafter shall use its best efforts to convene a
meeting of the shareholders of the Corporation or to seek written consents in
lieu thereof to obtain the Shareholder Approval. If (x) the Shareholder Approval
is sought but is not obtained at such meeting or any adjournment thereof (or
through solicitation of written consents), (y) the Corporation abandons its
efforts to obtain the Shareholder Approval or (z) the Shareholder Approval is
not obtained within 60 days after the earliest Inconvertibility Notice in
respect of which shares of Series B Convertible Preferred Stock have not been
redeemed by reason of the Corporation's decision to seek the Shareholder
Approval, then in each such case the Corporation shall thereafter promptly (but
in no event more than 10 days thereafter) redeem such portion (which may be all,
if all shares of Series B Convertible Preferred Stock are not convertible by
reason of the limitations in Section 4(a)(1)) of the outstanding shares of
Series B Convertible Preferred Stock as shall not, on the business day prior to
the date of such redemption, be convertible into shares of Common Stock by
reason of the limitations as set forth in Section 4(a)(1), on and subject to the
terms and conditions of this Section 4(a).

               (4) Notwithstanding the giving of any notice by the Corporation
to the holders of Series B Convertible Preferred Stock pursuant to Section
4(a)(1) or the giving or the absence of any notice by the holders of the Series
B Convertible Preferred Stock in response thereto or any redemption of shares of
Series B Convertible Preferred Stock pursuant to Section 4(a)(2), thereafter the
provisions of Section 4(a)(2) shall continue to be applicable on any occasion
unless the Shareholder Approval shall have been obtained from the shareholders
of the Corporation or waived by the Nasdaq.

               (5) As used herein, the term "Share Limitation Redemption Date"
means each date on which the Corporation is required to redeem shares of Series
B Convertible Preferred Stock as provided in this Section 4(a). On each Share
Limitation Redemption Date, the Corporation shall make payment in immediately
available funds of the applicable Share Limitation Redemption Price per share to
such holder of shares of Series B Convertible Preferred Stock to be redeemed to
or upon the order of such holder as specified by such holder in writing to the
Corporation at least one business day prior to such Share Limitation Redemption
Date. Upon redemption of less than all of the shares of Series B Convertible
Preferred Stock evidenced by a particular certificate, promptly, but in no event
later than three business days after surrender of such certificate to the
Corporation, the Corporation shall issue a replacement certificate for the
shares of Series B Convertible Preferred Stock evidenced by such certificate
that have not been redeemed. Only whole shares of Series B Convertible Preferred
Stock may be redeemed.

               (6) As used herein, the term "Share Limitation Redemption Price"
means the greater of (i) an amount in cash equal to the sum of (1) the product
obtained by multiplying (a) the sum of (I) $1,000.00 plus (II) an amount equal
to the accrued but unpaid dividends on the share of Series B Convertible
Preferred Stock to be redeemed to the

                                      -10-
<PAGE>
applicable Share Limitation Redemption Date times (b) 115% plus (2) an amount
equal to accrued and unpaid interest on dividends thereon in arrears on such
share of Series B Convertible Preferred Stock (determined as provided in Section
2) to the applicable Share Limitation Redemption Date and (ii) an amount equal
to the product obtained by multiplying (x) the number of shares of Common Stock
which would, but for redemption pursuant to Section 4(a), be issuable on
conversion in accordance with Section 7(a) of one share of Series B Convertible
Preferred Stock on the applicable Share Limitation Redemption Date (determined
without regard to any limitation on conversion contained in the second sentence
of Section 7(a)) times (y) the arithmetic average of the Closing Price of the
Common Stock for the five consecutive trading days ending on the trading day
immediately preceding such Share Limitation Redemption Date.

               (7) As used in this Section 4(a), "Shareholder Approval" means
the approval by a majority of the votes cast by the holders of shares of Common
Stock (in person or by proxy) at a meeting of the shareholders of the
Corporation (duly convened at which a quorum was present), or a written consent
of holders of shares of Common Stock entitled to such number of votes given
without a meeting, of the issuance by the Corporation of 20% or more of the
outstanding Common Stock of the Corporation for less than the greater of the
book or market value of such Common Stock on conversion of the Series B
Convertible Preferred Stock, as and to the extent required under Rule 4460(i) of
the Nasdaq National Market as in effect from time to time or any successor or
replacement provision thereto or of any similar provision of any other market on
which the Common Stock is listed for trading.

          (b) No Other Mandatory Redemption. The shares of Series B Convertible
Preferred Stock shall not be subject to mandatory redemption by the Corporation
except as provided herein.

     Section 5. No Sinking Fund.

     The shares of Series B Convertible Preferred Stock shall not be subject to
the operation of a purchase, retirement, or sinking fund.

     Section 6. Optional Redemption.

     So long as the Corporation is in compliance in all material respects with
its obligations to the holders of shares of Series B Convertible Preferred Stock
(including, without limitation, its obligations under the Registration Rights
Agreement (as defined in Section 7(b)) and the provisions of this Statement of
Rights and Preferences), the Corporation shall have the right, exercisable on
not less than 20 days or more than 30 days written notice to the holders of
record of the shares of Series B Convertible Preferred Stock to be redeemed, at
any time on or after the Initial Issuance Date (as defined in Section 7(b)) to

                                      -11-
<PAGE>
redeem all, and from time to time to redeem any part of not less than 200 shares
(or such lesser number of shares of Series B Convertible Preferred Stock as
shall remain outstanding at the time of exercise of such redemption right), of
Series B Convertible Preferred Stock in accordance with this Section 6. Any
notice of redemption (a "Notice of Redemption") under this Section shall be
delivered to the holders of the shares of Series B Convertible Preferred Stock
at their addresses appearing on the records of the Corporation; provided,
however, that any failure or defect in the giving of notice to any such holder
shall not affect the validity of notice to or the redemption of shares of Series
B Convertible Preferred Stock of any other holder. Any Notice of Redemption
shall state (1) that the Corporation is exercising its right to redeem all or a
portion of the outstanding shares of Series B Convertible Preferred Stock
pursuant to this Section 6, (2) the number of shares of Series B Convertible
Preferred Stock held by such holder which are to be redeemed, (3) the formula
for determining the Redemption Price (as defined below) per share of Series B
Convertible Preferred Stock, determined in accordance herewith, and (4) the date
of redemption of such shares of Series B Convertible Preferred Stock, determined
in accordance with this Section (the "Redemption Date"). On the Redemption Date
and after receipt by the Corporation of certificates for shares of Series B
Convertible Preferred Stock to be redeemed pursuant to this Section 6, the
Corporation shall make payment of the applicable Redemption Price to each holder
of shares of Series B Convertible Preferred Stock to be redeemed to or upon the
order of such holder as specified by such holder in writing to the Corporation
at least one business day prior to the Redemption Date. If the Corporation
exercises its right to redeem all or a portion of the outstanding shares of
Series B Convertible Preferred Stock the Corporation shall make payment to the
holders of the shares of Series B Convertible Preferred Stock to be redeemed in
respect of each share of Series B Convertible Preferred Stock to be redeemed of
an amount equal to the Redemption Price. Upon redemption of less than all of the
shares of Series B Convertible Preferred Stock evidenced by a particular
certificate, promptly, but in no event later than three business days after
surrender of such certificate to the Corporation, the Corporation shall issue
and deliver to the holder of record of the surrendered certificate (or such
holder's assignee) a replacement certificate for the shares of Series B
Convertible Preferred Stock that have not been redeemed. Only whole shares of
Series B Convertible Preferred Stock may be redeemed. If the Corporation
exercises its right to redeem less than all outstanding shares of Series B
Convertible Preferred Stock, then such redemption shall be made, as nearly as
practical, pro rata among the holders of record of the Series B Convertible
Preferred Stock. No share of Series B Convertible Preferred Stock as to which
the holder exercises the right of conversion pursuant to Section 7 or the
optional repurchase right pursuant to Section 8 may be redeemed by the
Corporation pursuant to this Section 6 on or after the date of exercise of such
conversion right or optional redemption right, as the case may be, regardless of
whether the Notice of Redemption shall have been given prior to the date of
exercise of such conversion right or optional redemption right, as the case may
be.

     As used herein, "Redemption Price" means the greater of (i) the sum of (a)
the product obtained by multiplying (1) the sum of (A) $1,000.00 plus (B) an
amount equal to

                                      -12-
<PAGE>
the accrued but unpaid dividends on the share of Series B Convertible Preferred
Stock to be redeemed to the date of payment of the Redemption Price times (2)
115% plus (b) an amount equal to the accrued and unpaid interest on dividends in
arrears (determined as provided in Section 2) through the Redemption Date, or
(ii) an amount equal to the product of (x) the number of shares of Common Stock
that would, but for the redemption pursuant to this Section 6, be issuable on
conversion in accordance with Section 7(a) of one share of Series B Convertible
Preferred Stock and any accrued and unpaid dividends thereon and any accrued and
unpaid interest on dividends thereon in arrears if a Conversion Notice were
given by the holder of such share of Series B Convertible Preferred Stock on the
Redemption Date (determined without regard to any limitation on conversion
contained in Section 7(a)) and (y) the arithmetic average of the Closing Price
(as defined in Section 2(b)) of the Common Stock during the five consecutive
trading days ending one trading day prior to the Redemption Date.

     Section 7. Conversion.

          (a) Conversion at Option of Holder. The holders of the Series B
Convertible Preferred Stock may convert any or all of their shares of Series B
Convertible Preferred Stock into fully paid and nonassessable shares of Common
Stock and such other securities and property as hereinafter provided, except
that no such conversion shall be for less than 50 shares of Series B Convertible
Preferred Stock unless the holder so converting holds less than 50 shares of
Series B Convertible Preferred Stock and is converting all of such shares held
by such holder. Commencing after the Initial Issuance Date and at any time
thereafter, each share of Series B Convertible Preferred Stock may be converted
at the office of the conversion agent for the Series B Convertible Preferred
Stock that was appointed prior to issuance of the shares of Series B Convertible
Preferred Stock or at such other additional office or offices, if any, as the
Board of Directors may designate, initially into such number of fully paid and
nonassessable shares of Common Stock (calculated as to each conversion to the
nearest 1/100th of a share) determined by dividing (x) the sum of (i) the
Conversion Amount, (ii) accrued but unpaid dividends to the applicable
Conversion Date on the share of Series B Convertible Preferred Stock being
converted, and (iii) accrued but unpaid interest on the dividends on the share
of Series B Convertible Preferred Stock being converted in arrears to the
applicable Conversion Date at the rate provided in Section 2 by (y) the lower of
(a) the product of (I) the Conversion Percentage with respect to the applicable
conversion date and (II) the lowest Market Price of the Common Stock during the
Measurement Period with respect to the applicable Conversion Date or (b) the
Ceiling Price, in each case subject to adjustment as hereinafter provided (the
"Conversion Rate"); provided, however, that in no event shall any holder of
shares of Series B Convertible Preferred Stock be entitled to convert any shares
of Series B Convertible Preferred Stock in excess of that number of shares of
Series B Convertible Preferred Stock upon conversion of which the sum of (1) the
number of shares of Common Stock beneficially owned by such holder and any
person whose beneficial ownership of shares of Common Stock would be aggregated
with such holder's

                                      -13-
<PAGE>
beneficial ownership of shares of Common Stock for purposes of Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
Regulation 13D-G thereunder (each a "Restricted Person" and collectively, the
"Restricted Persons") (other than shares of Common Stock deemed beneficially
owned by such holder or any Restricted Person of such holder through the
ownership of (x) unconverted shares of Series B Convertible Preferred Stock and
(y) the unconverted or unexercised portion of any instrument which contains
limitations similar to those set forth in this sentence) and (2) the number of
shares of Common Stock issuable upon the conversion of the number of shares of
Series B Convertible Preferred Stock with respect to which the determination in
this proviso is being made, would result in beneficial ownership by such holder
and all Restricted Persons of such holder of more than 4.9% of the outstanding
shares of Common Stock. For purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and Regulation 13D-G thereunder, except as otherwise
provided in clause (1) of the proviso to the immediately preceding sentence.

          (b) Certain Definitions.

applicable Issuance Date (which amount, with respect to shares of Series B
Convertible Preferred Stock whose Issuance Date is the Initial Issuance Date, is

for such use, the Registration Statement ceases to be so available for any
reason (including, without limitation, by reason of an SEC stop order, a
material misstatement or omission therein or the information contained in the

on such 30th day and each date that is the 30th day (whether or not consecutive)
after such 30th day on which the

                                      -15-

remain unable so to sell shares of Common Stock on such 32nd day and each date
that is 30 days after such 32nd day if holders remain unable to so sell;

provided, however, that if more than one event that could give rise to a

holder pursuant to Section 7(a).

     As used herein, "Conversion Percentage" shall mean 100%, provided, however,
that notwithstanding any other provision hereof (1) if (u) the Corporation shall
fail to file the Registration Statement with the SEC within 60 days after the

Corporation shall fail to request acceleration of the Registration Statement as
and when required by Section 3(a) of the Registration Rights Agreement, (x) the

Stock shall be unable to convert any shares of Series B Convertible Preferred
Stock in accordance with Section 7(a) (other than by reason of the 4.9%

     As used herein, the "Market Price" of any security on any date shall mean
the lowest sale price (regular way) per share of such security on such date on
the principal securities exchange or other market on which such security is

               distribution to all holders of the outstanding Common Stock in
               shares of Common

                                      -17-
<PAGE>
               Stock or fix any record date for any such action, then the Market
               Price of the Common Stock for each day in such Measurement Period
               prior to the earlier of (1) the date fixed for the determination
               of shareholders entitled to receive such dividend or other
               distribution and (2) the date on which ex-dividend trading in the
               Common Stock with respect to such dividend or distribution begins
               shall be reduced by multiplying the Market Price (determined
               without regard to this proviso) for each such day in such
               Measurement Period by a fraction of which the numerator shall be
               the number of shares of Common Stock outstanding at the close of
               business on the earlier of (1) the record date fixed for such
               determination and (2) the date on which ex-dividend trading in
               the Common Stock with respect to such dividend or distribution
               begins and the denominator shall be the sum of such number of
               shares and the total number of shares constituting such dividend
               or other distribution;

          (ii) The Corporation shall issue rights or warrants to all holders of
               its outstanding shares of Common Stock, or fix a record date for
               such issuance, which rights or warrants entitle such holders (for
               a period expiring within forty-five (45) days after the date
               fixed for the determination of shareholders entitled to receive
               such rights or warrants) to subscribe for or purchase shares of
               Common Stock at a price per share less than the Market Price
               (determined without regard to this proviso) for any day in such
               Measurement Period which is prior to the end of such 45-day
               period, then the Market Price for such day shall be reduced so
               that the same shall equal the price determined by multiplying the
               Market Price (determined without regard to this proviso) by a
               fraction of which the numerator shall be the number of shares of
               Common Stock outstanding at the close of business on the record
               date fixed for the determination of shareholders entitled to
               receive such rights or warrants plus the number of shares which
               the aggregate offering price of the total number of shares so
               offered would purchase at such Market Price, and of which the
               denominator shall be the number of shares of Common Stock
               outstanding on the close of business on such record date plus the
               total number of additional shares of Common Stock so offered for
               subscription or purchase. In determining whether any rights or
               warrants entitle the holders to subscribe for or purchase shares
               of Common Stock at less than the Market Price (determined without
               regard to this proviso), and in determining the aggregate
               offering price of such shares of Common Stock, there shall be
               taken into account any consideration received for such rights or
               warrants, the value of such consideration, if other than

                                      -18-
<PAGE>
               cash, to be determined in good faith by a resolution of the Board
               of Directors of the Corporation;

          (iii) The outstanding shares of Common Stock shall be subdivided into
               a greater number of shares of Common Stock or a record date for
               any such subdivision shall be fixed, then the Market Price of the
               Common Stock for each day in such Measurement Period prior to the
               earlier of (1) the day upon which such subdivision becomes
               effective and (2) the date on which ex-dividend trading in the
               Common Stock with respect to such subdivision begins shall be
               proportionately reduced, and conversely, in case the outstanding
               shares of Common Stock shall be combined into a smaller number of
               shares of Common Stock, the Market Price for each day in such
               Measurement Period prior to the day upon which such combination
               becomes effective shall be proportionately increased;

          (iv) The Corporation shall, by dividend or otherwise, distribute to
               all holders of its Common Stock shares of any class of capital
               stock of the Corporation (other than any dividends or
               distributions to which clause (i) of this proviso applies) or
               evidences of its indebtedness, cash or other assets (including
               securities, but excluding any rights or warrants referred to in
               clause (ii) of this proviso and dividends and distributions paid
               exclusively in cash and excluding any capital stock, evidences of
               indebtedness, cash or assets distributed upon a merger or
               consolidation) (the foregoing hereinafter in this clause (iv) of
               this proviso called the "Securities"), or fix a record date for
               any such distribution, then, in each such case, the Market Price
               for any day in such Measurement Period prior to the earlier of
               (1) the record date for such distribution and (2) the date on
               which ex-dividend trading in the Common Stock with respect to
               such distribution begins shall be reduced so that the same shall
               be equal to the price determined by multiplying the Market Price
               (determined without regard to this proviso) by a fraction of
               which the numerator shall be the Market Price (determined without
               regard to this proviso) on such date less the fair market value
               (as determined in good faith by resolution of the Board of
               Directors of the Corporation) on such date of the portion of the
               Securities so distributed or to be distributed applicable to one
               share of Common Stock and the denominator shall be the Market
               Price (determined without regard to this proviso); provided,
               however, that in the event the then fair market value (as so
               determined) of the portion of the Securities so distributed
               applicable to one share of Common Stock is equal to or greater
               than the Market Price (determined without regard to this clause
               (iv) of this

                                      -19-
<PAGE>
               proviso) on any such day, in lieu of the foregoing adjustment,
               adequate provision shall be made so that the holders of shares of
               Series B Convertible Preferred Stock shall have the right to
               receive in payment of dividends on the shares of Series B
               Convertible Preferred Stock or upon conversion of the shares of
               Series B Convertible Preferred Stock, as the case may be, the
               amount of Securities the holders of shares of Series B
               Convertible Preferred Stock would have received had the number of
               shares of Common Stock to be issued in payment of such dividends
               on the shares of Series B Convertible Preferred Stock, or had the
               holders of shares of Series B Convertible Preferred Stock
               converted the shares of Series B Convertible Preferred Stock, in
               either such case immediately prior to the record date for such
               distribution. If the Board of Directors of the Corporation
               determines the fair market value of any distribution for purposes
               of this clause (iv) by reference to the actual or when issued
               trading market for any securities comprising all or part of such
               distribution, it must in doing so consider the prices in such
               market on the same day for which an adjustment in the Market
               Price is being determined.

     For purposes of this clause (iv) and clauses (i) and (ii) of this proviso,
     any dividend or distribution to which this clause (iv) is applicable that
     also includes shares of Common Stock, or rights or warrants to subscribe
     for or purchase shares of Common Stock to which clause (ii) of this proviso
     applies (or both), shall be deemed instead to be (1) a dividend or
     distribution of the evidences of indebtedness, assets, shares of capital
     stock, rights or warrants other than such shares of Common Stock or rights
     or warrants to which clause (ii) of this proviso applies (and any Market
     Price reduction required by this clause (iv) with respect to such dividend
     or distribution shall then be made) immediately followed by (2) a dividend
     or distribution of such shares of Common Stock or such rights or warrants
     (and any further Market Price reduction required by clauses (i) and (ii) of
     this proviso with respect to such dividend or distribution shall then be
     made), except that any shares of Common Stock included in such dividend or
     distribution shall not be deemed "outstanding at the close of business on
     the date fixed for such determination" within the meaning of clause (i) of
     this proviso;

          (v)  The Corporation or any subsidiary of the Corporation shall (x) by
               dividend or otherwise, distribute to all holders of its Common
               Stock cash in (or fix any record date for any such distribution),
               or (y) repurchase or reacquire shares of its Common Stock for, in
               either case, an aggregate amount that, combined with (1) the
               aggregate amount of any other such distributions to all holders
               of its Common Stock made exclusively in cash within the twelve
               (12) months preceding the date of

                                      -20-
<PAGE>
               payment of such distribution, and in respect of which no
               adjustment pursuant to this clause (v) has been made, (2) the
               aggregate amount of any cash plus the fair market value (as
               determined in good faith by a resolution of the Board of
               Directors of the Corporation) of consideration paid in respect of
               any repurchase or other reacquisition by the Corporation or any
               subsidiary of the Corporation of any shares of Common Stock made
               within the twelve (12) months preceding the date of payment of
               such distribution or making of such repurchase or reacquisition,
               as the case may be, and in respect of which no adjustment
               pursuant to this clause (v) has been made, and (3) the aggregate
               of any cash plus the fair market value (as determined in good
               faith by a resolution of the Board of Directors of the
               Corporation) of consideration payable in respect of any tender
               offer by the Corporation or any of its subsidiaries for all or
               any portion of the Common Stock concluded within the twelve (12)
               months preceding the date of payment of such distribution or
               completion of such repurchase or reacquisition, as the case may
               be, and in respect of which no adjustment pursuant to clause (vi)
               of this proviso has been made, exceeds 10% of the product of the
               Market Price (determined without regard to this proviso) on any
               day in such Measurement Period prior to the earlier of (1) the
               record date with respect to such distribution and (2) the date on
               which ex-dividend trading in the Common Stock with respect to
               such distribution begins or the date of such repurchase or
               reacquisition, as the case may be, times the number of shares of
               Common Stock outstanding on such date, then, and in each such
               case, the Market Price for such day shall be reduced so that the
               same shall equal the price determined by multiplying the Market
               Price (determined without regard to this proviso) for such day by
               a fraction (i) the numerator of which shall be equal to the
               Market Price (determined without regard to this proviso) for such
               day less an amount equal to the quotient of (x) the excess of
               such combined amount over such 10% and (y) the number of shares
               of Common Stock outstanding on such day and (ii) the denominator
               of which shall be equal to the Market Price (determined without
               regard to this proviso) on such day; provided, however, that in
               the event the portion of the cash so distributed or paid for the
               repurchase or reacquisition of shares (determined per share based
               on the number of shares of Common Stock outstanding) applicable
               to one share of Common Stock is equal to or greater than the
               Market Price (determined without regard to this clause (v) of
               this proviso) of the Common Stock on any such day, in lieu of the
               foregoing adjustment, adequate provision shall be made so that
               the holders of shares of Series B Convertible Preferred Stock
               shall have the right to receive in

                                      -21-
<PAGE>
               payment of dividends on shares of Series B Convertible Preferred
               Stock or upon conversion of shares of Series B Convertible
               Preferred Stock, as the case may be, the amount of cash the
               holders of shares of Series B Convertible Preferred Stock would
               have received had the number of shares of Common Stock to be
               issued in payment of such dividends on shares of Series B
               Convertible Preferred Stock, or had the holders of shares of
               Series B Convertible Preferred Stock converted shares of Series B
               Convertible Preferred Stock, in either such case, immediately
               prior to the record date for such distribution or the payment
               date of such repurchase, as applicable; or

          (vi) A Tender Offer for all or any portion of the Common Stock shall
               expire and such Tender Offer (as amended upon the expiration
               thereof) shall require the payment to shareholders (based on the
               acceptance (up to any maximum specified in the terms of the
               Tender Offer) of Purchased Shares (as defined below)) of an
               aggregate consideration having a fair market value (as determined
               in good faith by resolution of the Board of Directors of the
               Corporation) that combined together with (1) the aggregate of the
               cash plus the fair market value (as determined in good faith by a
               resolution of the Board of Directors of the Corporation), as of
               the expiration of such Tender Offer, of consideration payable in
               respect of any other Tender Offers, by the Corporation or any of
               its subsidiaries for all or any portion of the Common Stock
               expiring within the twelve (12) months preceding the expiration
               of such Tender Offer and in respect of which no adjustment
               pursuant to this clause (vi) has been made, (2) the aggregate
               amount of any cash plus the fair market value (as determined in
               good faith by a resolution of the Board of Directors of the
               Corporation) of consideration paid in respect of any repurchase
               or other reacquisition by the Corporation or any subsidiary of
               the Corporation of any shares of Common Stock made within the
               twelve (12) months preceding the expiration of such Tender Offer
               and in respect of which no adjustment pursuant to this clause
               (vi) has been made, and (3) the aggregate amount of any
               distributions to all holders of the Corporation's Common Stock
               made exclusively in cash within twelve (12) months preceding the
               expiration of such Tender Offer and in respect of which no
               adjustment pursuant to clause (v) of this proviso has been made,
               exceeds 10% of the product of the Market Price (determined
               without regard to this proviso) on any day in such period times
               the number of shares of Common Stock outstanding on such day,
               then, and in each such case, the Market Price for such day shall
               be reduced so that the same shall equal the price determined by
               multiplying the Market Price (determined

                                      -22-
<PAGE>
               without regard to this proviso) for such day by a fraction of
               which the numerator shall be the number of shares of Common Stock
               outstanding on such day multiplied by the Market Price
               (determined without regard to this proviso) for such day and the
               denominator shall be the sum of (x) the fair market value
               (determined as aforesaid) of the aggregate consideration payable
               to shareholders based on the acceptance (up to any maximum
               specified in the terms of the Tender Offer) of all shares validly
               tendered and not withdrawn as of the last time tenders could have
               been made pursuant to such Tender Offer (the "Expiration Time")
               (the shares deemed so accepted, up to any such maximum, being
               referred to as the "Purchased Shares") and (y) the product of the
               number of shares of Common Stock outstanding (less any Purchased
               Shares) on such day and the Market Price (determined without
               regard to this proviso) of the Common Stock on the trading day
               next succeeding the Expiration Time. If the application of this
               clause (vi) to any Tender Offer would result in an increase in
               the Market Price (determined without regard to this proviso) for
               any day, no adjustment shall be made for such Tender Offer under
               this clause (vi) for such day;

provided further, however, that if on any date there shall be no reported sale
price (regular way) of such security, the "Market Price" on such date shall be
the lowest sale price (regular way) of such security on the date next preceding
such date on which a sale price for such security has been so reported; provided
further, however, that if on any date there shall be no reported sale price of
such security and at the time the lowest sale price for such date is being
determined there shall be a sale price so reported for the date next subsequent
to such date on which a sale price shall have been so reported, then the Market
Price on such date for which there shall have been no reported sale price shall
be the lower of (x) the Market Price as determined pursuant to the second
proviso to this definition and (y) the lowest sale price (regular way) as so
reported for such succeeding day for which a sale price as so reported is known.

of the shares of Series B Convertible Preferred Stock, as amended or modified
from time to time in accordance with its terms.

          (c) Other Provisions.

               (1) Notwithstanding anything in this Section 7(c) to the
contrary, no change in the Conversion Amount pursuant to Section 7(c) shall
actually be made until the cumulative effect of the adjustments called for by
this Section 7(c) since the date of the last change in the Conversion Amount
would change the Conversion Amount by more than 1%. However, once the cumulative
effect would result in such a change, then the Conversion Rate shall actually be
changed to reflect all adjustments called for by this Section 7(c) and not
previously made. Notwithstanding anything in this Section 7(c), no change in the
Conversion Amount shall be made that would result in a Conversion Price of less
than the par value of the Common Stock into which shares of Series B Convertible
Preferred Stock are at the time convertible.

               (2) The holders of shares of Series B Convertible Preferred Stock
at the close of business on the record date for any dividend payment to holders
of Series B Convertible Preferred Stock shall be entitled to receive the
dividend payable on such shares on the corresponding dividend payment date
notwithstanding the conversion thereof after such dividend payment record date
or the Corporation's default in payment of the dividend due on such dividend
payment date; provided, however, that the holder of shares of Series B
Convertible Preferred Stock surrendered for conversion during the period between
the close of business on any record date for a dividend payment and the opening
of business on the

                                      -24-
<PAGE>
corresponding dividend payment date must pay to the Corporation, within five
days after receipt by such holder, an amount equal to the dividend payable on
such shares on such dividend payment date if such dividend is paid by the
Corporation to such holder. A holder of shares of Series B Convertible Preferred
Stock on a record date for a dividend payment who (or whose transferee) tenders
any of such shares for conversion into shares of Common Stock on or after such
dividend payment date will receive the dividend payable by the Corporation on
such shares of Series B Convertible Preferred Stock on such date, and the
converting holder need not make any payment of the amount of such dividend in
connection with such conversion of shares of Series B Convertible Preferred
Stock. Except as provided above, no adjustment shall be made in respect of cash
dividends on Common Stock or Series B Convertible Preferred Stock that may be
accrued and unpaid at the date of surrender of shares of Series B Convertible
Preferred Stock.

               (3) The right of the holders of Series B Convertible Preferred
Stock to convert their shares shall be exercised by delivering (which may be
done by facsimile) to the conversion agent, as provided above, a written notice,
duly signed by or on behalf of the holder, stating the number of shares of
Series B Convertible Preferred Stock to be converted in the form specified in
the subscription agreements therefor (the "Conversion Notice"). If a holder of
Series B Convertible Preferred Stock elects to convert any shares of Series B
Convertible Preferred Stock in accordance with Section 7(a), such holder shall
not be required to physically surrender the certificate(s) representing such
shares of Series B Convertible Preferred Stock to the Corporation unless all of
the shares of Series B Convertible Preferred Stock represented thereby are so
converted. Each holder of shares of Series B Convertible Preferred Stock and the
Corporation shall maintain records showing the number of shares so converted and
the dates of such conversions or shall use such other method, satisfactory to
such holder and the Corporation, so as to not require physical surrender of such
certificates upon each such conversion. In the event of any dispute or
discrepancy, such records of the Corporation shall be controlling and
determinative in the absence of manifest error. Notwithstanding the foregoing,
if any shares of Series B Convertible Preferred Stock evidenced by a particular
certificate therefor are converted as aforesaid, the holder of Series B
Convertible Preferred Stock may not transfer the certificate(s) representing
such shares of Series B Convertible Preferred Stock unless such holder first
physically surrenders such certificate(s) to the Corporation, whereupon the
Corporation will forthwith issue and deliver upon the order of such holder of
shares of Series B Convertible Preferred Stock new certificate(s) of like tenor,
registered as such holder of shares of Series B Convertible Preferred Stock
(upon payment by such holder of shares of Series B Convertible Preferred Stock
of any applicable transfer taxes) may request, representing in the aggregate the
remaining number of shares of Series B Convertible Preferred Stock represented
by such certificate(s). Each holder of shares of Series B Convertible Preferred
Stock, by acceptance of a certificate for such shares, acknowledges and agrees
that (1) by reason of the provisions of this paragraph and Section 6, following
conversion of any shares of Series B Convertible Preferred Stock represented by
such

                                      -25-
<PAGE>
certificate, the number of shares of Series B Convertible Preferred Stock
represented by such certificate may be less than the number of shares stated on
such certificate and the number of shares of Common Stock from the Maximum Share
Amount allocated to the shares of Series B Convertible Preferred Stock
represented by such certificate for purposes of conversion of such shares may be
less than the number thereof on such certificate and (2) the Corporation may
place a legend on the certificates for shares of Series B Convertible Preferred
Stock which refers to or describes the provisions of this paragraph. The
Corporation shall pay any tax arising in connection with any conversion of
shares of Series B Convertible Preferred Stock except that the Corporation shall
not, however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery upon conversion of shares of Common
Stock or other securities or property in a name other than that of the holder of
the shares of the Series B Convertible Preferred Stock being converted, and the
Corporation shall not be required to issue or deliver any such shares or other
securities or property unless and until the person or persons requesting the
issuance thereof shall have paid to the Corporation the amount of any such tax
or shall have established to the satisfaction of the Corporation that such tax
has been paid. The number of shares of Common Stock to be issued upon each
conversion of shares of Series B Convertible Preferred Stock shall be the number
set forth in the applicable Conversion Notice which number shall be conclusive
absent manifest error. The Corporation shall notify a holder who has given a
Conversion Notice of any claim of manifest error within two business days after
such holder gives such Conversion Notice and no such claim of error shall limit
or delay performance of the Corporation's obligation to issue upon such
conversion the number of shares of Common Stock which are not in dispute. A
Conversion Notice shall be deemed for all purposes to be in proper form unless
the Corporation notifies a holder of shares of Series B Convertible Preferred
Stock being converted within two business days after a Conversion Notice has
been received (which notice shall specify all defects in the Conversion Notice)
and any Conversion Notice containing any such defect shall nonetheless be
effective on the date given if the converting holder promptly undertakes in
writing to correct all such defects.

               (4) The Corporation (and any successor corporation) shall take
all action necessary so that a number of shares of the authorized but unissued
Common Stock (or common stock in the case of any successor corporation)
sufficient to provide for the conversion of the Series B Convertible Preferred
Stock outstanding upon the basis hereinbefore provided are at all times reserved
by the Corporation (or any successor corporation), free from preemptive rights,
for such conversion, subject to the provisions of the next succeeding paragraph.
If the Corporation shall issue any securities or make any change in its capital
structure that would change the number of shares of Common Stock into which each
share of the Series B Convertible Preferred Stock shall be convertible as herein
provided, the Corporation shall at the same time also make proper provision so
that thereafter there shall be a sufficient number of shares of Common Stock
authorized and reserved, free from preemptive rights, for conversion of the
outstanding Series B Convertible

                                      -26-
<PAGE>
Preferred Stock on the new basis. If at any time the number of authorized but
unissued shares of Common Stock shall not be sufficient to effect the conversion
of all of the outstanding shares of Series B Convertible Preferred Stock, the
Corporation promptly shall take such corporate action as may, in the opinion of
its counsel, be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose.

               (5) In case of any consolidation or merger of the Corporation
with any other corporation (other than a wholly-owned subsidiary of the
Corporation) in which the Corporation is not the surviving corporation, or in
case of any sale or transfer of all or substantially all of the assets of the
Corporation, or in the case of any share exchange pursuant to which all of the
outstanding shares of Common Stock are converted into other securities or
property, the Corporation shall make appropriate provision or cause appropriate
provision to be made so that each holder of shares of Series B Convertible
Preferred Stock then outstanding shall have the right thereafter to convert such
shares of Series B Convertible Preferred Stock into the kind of shares of stock
and other securities and property receivable upon such consolidation, merger,
sale, transfer, or share exchange by a holder of shares of Common Stock into
which such shares of Series B Convertible Preferred Stock could have been
converted immediately prior to the effective date of such consolidation, merger,
sale, transfer, or share exchange and on a basis which preserves the economic
benefits of the conversion rights of the holders of shares of Series B
Convertible Preferred Stock on a basis as nearly as practical as such rights
exist hereunder prior thereto. If, in connection with any such consolidation,
merger, sale, transfer, or share exchange, each holder of shares of Common Stock
is entitled to elect to receive securities, cash, or other assets upon
completion of such transaction, the Corporation shall provide or cause to be
provided to each holder of Series B Convertible Preferred Stock the right to
elect the securities, cash, or other assets into which the Series B Convertible
Preferred Stock held by such holder shall be convertible after completion of any
such transaction on the same terms and subject to the same conditions applicable
to holders of the Common Stock (including, without limitation, notice of the
right to elect, limitations on the period in which such election shall be made,
and the effect of failing to exercise the election). The Corporation shall not
effect any such transaction unless the provisions of this paragraph have been
complied with. The above provisions shall similarly apply to successive
consolidations, mergers, sales, transfers, or share exchanges.

               (6) If a holder shall have given a Conversion Notice for shares
of Series B Convertible Preferred Stock, the Corporation shall issue and deliver
to such person certificates for the Common Stock issuable upon such conversion
within three business days after such Conversion Notice is received and the
person converting shall be deemed to be the holder of record of the Common Stock
issuable upon such conversion as of the date of receipt, and all rights with
respect to the shares surrendered shall forthwith terminate except the right to
receive the Common Stock or other securities, cash, or other assets as herein

                                      -27-
<PAGE>
provided. If a holder shall have given a Conversion Notice as provided herein,
the Corporation's obligation to issue and deliver the certificates for Common
Stock shall be absolute and unconditional, irrespective of any action or
inaction by the converting holder to enforce the same, any waiver or consent
with respect to any provision thereof, the recovery of any judgment against any
person or any action to enforce the same, any failure or delay in the
enforcement of any other obligation of the Corporation to the holder of record,
or any set off, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the holder of any obligation to the Corporation, and
irrespective of any other circumstance that might otherwise limit such
obligation of the Corporation to the holder in connection with such conversion.
If the Corporation fails to issue and deliver the certificates for the Common
Stock to the holder converting shares of Series B Convertible Preferred Stock
pursuant to the first sentence of this paragraph as and when required to do so,
in addition to any other liabilities the Corporation may have hereunder and
under applicable law (1) the Corporation shall pay or reimburse such holder on
demand for all out-of-pocket expenses including, without limitation, fees and
expenses of legal counsel incurred by such holder as a result of such failure,
(2) the Conversion Rate applicable to such conversion shall be reduced by three
percentage points from the Conversion Rate applicable to such conversion and (3)
such holder may by written notice (which may be given by mail, courier, personal
service or facsimile) or oral notice (promptly confirmed in writing) given at
any time prior to delivery to such holder of the certificates for the shares of
Common Stock issuable upon such conversion of shares of Series B Convertible
Preferred Stock, rescind such conversion, whereupon such holder shall have the
right to convert such shares of Series B Convertible Preferred Stock thereafter
in accordance herewith.

               (7) No fractional shares of Common Stock shall be issued upon
conversion of Series B Convertible Preferred Stock but, in lieu of any fraction
of a share of Common Stock that would otherwise be issuable in respect of the
aggregate number of such shares surrendered for conversion at one time by the
same holder, the Corporation shall pay in cash an amount equal to the product of
(i) the arithmetic average of the Closing Price of a share of Common Stock on
the three consecutive trading days ending on the trading day immediately
preceding the Conversion Date and (ii) such fraction of a share.

               (8) The Conversion Amount shall be adjusted from time to time
under certain circumstances, subject to the provisions of the first three
sentences of the first paragraph of this Section 7(c), as follows:

                    (i) In case the Corporation shall issue rights or warrants
on a pro rata basis to all holders of the Common Stock entitling such holders to
subscribe for or purchase Common Stock on the record date referred to below at a
price per share less than the average daily Closing Prices of the Common Stock
on the 30 consecutive business days commencing 45 business days before the
record date (the "Current Market Price"), then in

                                      -28-
<PAGE>
each such case the Conversion Amount in effect on such record date shall be
adjusted in accordance with the formula

                           C1 = C  x    O + N
                                     ----------
                                      O + N x P
                                          -----
                                            M

     where

          C1 =  the adjusted Conversion Amount
          C  =  the current Conversion Amount
          O  =  the number of shares of Common Stock outstanding on the record
                date.
          N  =  the number of additional shares of Common Stock issuable
                pursuant to the exercise of such rights or warrants
          P  =  the offering price per share of the additional shares (which
                amount shall include amounts received by the Corporation in
                respect of the issuance and the exercise of such rights or
                warrants)
          M  =  the Current Market Price per share of Common Stock on the
                record date.

     Such adjustment shall become effective immediately after the record date
     for the determination of shareholders entitled to receive such rights or
     warrants. If any or all such rights or warrants are not so issued or expire
     or terminate before being exercised, the Conversion Amount then in effect
     shall be readjusted appropriately.

   
                    (ii) In case the Corporation shall, by dividend or
otherwise, distribute to all holders of its Junior Stock (as defined below)
evidences of its indebtedness or assets (including securities, but excluding any
rights or warrants referred to in subparagraph (i) above and any dividend or
distribution paid in cash out of the retained earnings of the Corporation), then
in each such case the Conversion Amount then in effect shall be adjusted in
accordance with the formula
    

                           C1 = C  x    M
                                      -----
                                      M - F

     where

          C1 =  the adjusted Conversion Amount
          C  =  the current Conversion Amount
          M  =  the Current Market Price per share of Common Stock on the
                record date mentioned below
          F  =  the aggregate amount of such cash dividend and/or the fair
                market value on the record date of the assets or securities to
                be distributed

                                      -29-
<PAGE>
                divided by the number of shares of Common Stock outstanding on
                the record date. The Board of Directors shall determine such
                fair market value, which determination shall be conclusive.

         Such adjustment shall become effective immediately after the record
         date for the determination of shareholders entitled to receive such
         dividend or distribution. For purposes of this subparagraph (ii),
         "Junior Stock" shall include any class of capital stock ranking junior
         as to dividends or upon liquidation to the Series B Convertible
         Preferred Stock.

                    (iii) All calculations hereunder shall be made to the
nearest cent or to the nearest 1/100 of a share, as the case may be.

                    (iv) If at any time as a result of an adjustment made
pursuant to Section 7(c)(5), the holder of any Series B Convertible Preferred
Stock thereafter surrendered for conversion shall become entitled to receive
securities, cash, or assets other than Common Stock, the number or amount of
such securities or property so receivable upon conversion shall be subject to
adjustment from time to time in a manner and on terms nearly equivalent as
practicable to the provisions with respect to the Common Stock contained in
subparagraphs (i) to (iii) above.

               (9) Except as otherwise provided above in this Section 7, no
adjustment in the Conversion Amount shall be made in respect of any conversion
for share distributions or dividends theretofore declared and paid or payable on
the Common Stock.

on which the books of the Corporation will close or on which a record will be
taken for such action, to the holders of record of the outstanding Series B

specify the action proposed to be taken by the Corporation and the date as of
which holders of record of the Common Stock shall participate in any such
actions or be entitled to exchange their Common Stock for securities or other
property, as the case may be. Failure by the Corporation to mail the notice or
any defect in such notice shall not affect the validity of the transaction.

Registration Rights Agreements and the provisions of this Statement of Rights

Preferred Stock (or such lesser number of shares of Series B Convertible
Preferred Stock as are convertible into Common Stock on the Mandatory Conversion

determined pursuant to this Section 7 as if the conversion of such number of

     The Company represents and warrants to, and covenants and agrees with, the
Buyer that:

          (a) Organization and Authority. The Company is a corporation duly
organized and validly existing under the laws of the State of Washington, and
has all requisite corporate power and authority (i) to own, lease and operate
its properties and to carry on its business as now being conducted, and (ii) to
execute, deliver and perform its obligations under this Agreement, the
Registration Rights Agreement, the Statement of Rights, the Warrants, the
Additional Warrants, and the other agreements to be executed and delivered by
the Company in connection herewith, and to consummate the transactions
contemplated hereby and thereby. The Company is duly qualified to do business as
a foreign corporation and is in good standing in all jurisdictions wherein such
qualification is necessary and where failure so to qualify could have a material
adverse effect on the business, properties, operations, condition (financial or
other), results of operations or prospects of the Company. The Company has no
subsidiaries.

          (b) Capitalization. The authorized capital stock of the Company
currently consists of (a) 25,000,000 shares of Common Stock, of which 12,188,775
shares were outstanding as of June 29, 1998, all of which are fully paid and
nonassessable; and (b) 5,000,000 shares of Preferred Stock, $.01 par value, of
which (i) 10,000 shares are designated as Series A Convertible Preferred Stock,
of which 5,890 shares are outstanding; (ii) 12,000 shares will be designated as
Series B Convertible Preferred Stock prior to the Closing Date; and (iii) 5,000
shares are designated as Series C Convertible Preferred Stock, none of which are
outstanding. As of June 29, 1998, the Company had outstanding options entitling
the holders thereof to purchase 2,071,213 shares of Common Stock and outstanding
warrants entitling the holders thereof to purchase 782,196 shares of Common
Stock. As of the Closing Date, there will have been no material increase from
June 29, 1998 in the number of shares of Common Stock outstanding other than
pursuant to the exercise of outstanding options or warrants or the conversion of
outstanding shares of Series A Stock or both. The Company does not have
outstanding any material amount of securities (or obligations to issue any such
securities) convertible into, exchangeable for or otherwise entitling the
holders thereof to acquire shares of Common Stock, except as disclosed above or
in the Disclosure Documents or as set forth in Section 3(b) of the disclosure
letter delivered to the Buyer at or before the execution of this Agreement (the
"Disclosure Letter"). The outstanding shares of Common Stock and outstanding
options, warrants, and other securities to purchase Common Stock have been duly
authorized and validly issued.

                                       -7-
<PAGE>
None of such outstanding shares of Common Stock, options, warrants, and other
securities has been issued in violation of the preemptive rights of any security
holder of the Company. The offers and sales of the outstanding shares of Common
Stock and options, warrants and other rights to acquire Common Stock were at all
relevant times either registered under the 1933 Act and applicable state
securities laws or exempt from such requirements. No holder of any of the
Company's securities has any rights, "demand," "piggy-back" or otherwise, to
have such securities registered by reason of the intention to file, filing or
effectiveness of the Registration Statement (as defined in the Registration
Rights Agreement), except for Advantage Fund II Ltd. and Genesee Fund Limited -
Portfolio B and as set forth in Section 3(b) of the Disclosure Letter.

          (c) Concerning the Securities. The Securities have been duly
authorized and the Preferred Shares and Option Shares, when issued and paid for
in accordance with this Agreement, and the Common Shares, when issued upon
conversion of the Preferred Shares and Option Shares or in payment of dividends
thereon or upon exercise of the Warrants and the Additional Warrants, as the
case may be, will be duly and validly issued, fully paid and non-assessable, and
will not subject the holder thereof to personal liability by reason of being
such holder. There are no preemptive or similar rights of any security holder of
the Company or any other person to acquire any of the Shares. The Common Stock
is listed for trading on the Nasdaq National Market ("Nasdaq") and, except as
set forth in Section 3(c) of the Disclosure Letter, (i) the Company and the
Common Stock meet the currently applicable criteria for continued listing and
trading on Nasdaq; (ii) the Company has not been notified since September 25,
1995, by Nasdaq of any failure or potential failure to meet the criteria for
continued listing and trading on Nasdaq; (iii) no suspension of trading in the
Common Stock is in effect; and (iv) the Company knows of no reason that the
Common Shares will not be eligible for listing on Nasdaq.

          (d) Subscription Agreement; Warrants; Registration Rights Agreement.
This Agreement, the Warrants and the Additional Warrants, and the Registration
Rights Agreement have been duly and validly authorized by the Company, this
Agreement has been duly executed and delivered on behalf of the Company and this
Agreement is, and the Warrants, the Additional Warrants, and the Registration
Rights Agreement, when executed and delivered by the Company, will be, valid and
binding obligations of the Company enforceable in accordance with their
respective terms, subject as to enforceability to general principles of equity
and to bankruptcy, insolvency, moratorium and other similar laws affecting the
enforcement of creditors' rights generally and limits upon rights to indemnity.

          (e) Non-contravention. The execution and delivery of this Agreement by
the Company and the consummation by the Company of the issuance of the Preferred
Shares, Option Shares, the Warrants, and the Additional Warrants, as
contemplated by this Agreement and completion of the other transactions
contemplated by this Agreement, the Registration Rights Agreement and the terms
of the Preferred Stock, Warrants and the Additional Warrants do not and will not
conflict with or result in a breach by the Company

                                       -8-
<PAGE>
of any of the terms or provisions of, or constitute a default under, the
Restated Articles of Incorporation or Bylaws of the Company, or any indenture,
mortgage, deed of trust or other material agreement or instrument to which the
Company is a party or by which it or any of its properties or assets are bound
which would have a material adverse effect on the Company or any applicable law,
rule or regulation or any applicable decree, judgment or order of any court,
United States federal or state regulatory body, administrative agency or other
governmental body having jurisdiction over the Company or any of its properties
or assets which would have a material adverse effect on the Company.

          (f) Approvals. No authorization, approval or consent of any court,
governmental body, regulatory agency, self-regulatory organization, or stock
exchange or market or the shareholders of the Company is required to be obtained
by the Company for (i) the issuance and sale of the Preferred Shares and Option
Shares, and the issuance of the Warrants and the Additional Warrants, as
contemplated by this Agreement, and (ii) the issuance of Common Shares on
conversion of the Preferred Shares and Option Shares or exercise of the Warrants
and the Additional Warrants.

          (g) Information Provided. The information provided by or on behalf of
the Company to the Buyer in connection with the transactions contemplated by the
Agreement, including, without limitation, the information referred to in Section
3(e) of this Agreement, does not contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstance under which they are made, not
misleading.

          (h) Absence of Certain Changes. Since December 31, 1997, there has
been no material adverse change and no material adverse development in the
business, properties, operations, condition (financial or other), results of
operations or prospects of the Company, except as disclosed in the Disclosure
Documents.

          (i) Absence of Certain Proceedings. There is no action, suit or
proceeding, before or by any court, public board or body or governmental agency
(an "Action") pending or, to the knowledge of the Company, threatened against
the Company and, to the knowledge of the Company, there is no inquiry or
investigation before or by any court, public board or body or governmental
agency pending or threatened against the Company, in any such case wherein an
unfavorable decision, ruling or finding would have a material adverse effect on
the properties, business, condition (financial or other), results of operations
or prospects of the Company taken as a whole or the transactions contemplated by
this Agreement or any of the documents contemplated hereby or which would
adversely affect the validity or enforceability of, or the authority or ability
of the Company to perform its obligations under, this Agreement or any of such
other documents. Neither the Company nor any director or officer thereof is or
has been the subject of any Action involving (i) a claim of violation of or
liability under federal or state securities laws or (ii) a claim of breach of
fiduciary duty. The Company does not have pending before the SEC any request for

                                       -9-
<PAGE>
confidential treatment of information and to the best of the Company's knowledge
no such request will be made by the Company prior to the time the Registration
Statement relating to the Common Shares which is contemplated by the
Registration Rights Agreement is first ordered effective by the SEC; and to the
best of the Company's knowledge there is not pending or contemplated and has not
been any investigation by the SEC of the Company or any director or officer of
the Company.

          (j) Properties. The Company has good title to all property, real and
personal (tangible and intangible), and other assets owned by it, free and clear
of all security interests, charges, mortgages, liens or other encumbrances,
except such as are described in the Disclosure Documents or such as do not
materially interfere with the use of such property made, or proposed to be made,
by the Company. The leases, licenses or other contracts or instruments under
which the Company leases, holds or is entitled to use any property, real or
personal, are valid, subsisting and enforceable with only such exceptions as do
not materially interfere with the use of such property made, or proposed to be
made, by the Company. The Company has received no notice of any material
violation of any applicable law, ordinance, regulation, order or requirement
relating to its owned or leased properties.

          (k) Labor Relations. No material labor problem exists or, to the
knowledge of the Company, is imminent with respect to any of the employees of
the Company.

          (l) SEC Filings. The Company has timely filed all required forms,
reports and other documents with the SEC. All of such forms, reports and other
documents complied, when filed, in all material respects, with all applicable
requirements of the 1933 Act and the 1934 Act.

          (m) Absence of Brokers, Finders, Etc. No broker, finder or similar
person is entitled to any commission, fee or other compensation by reason of the
transactions contemplated by this Agreement and the Company shall pay, and
indemnify and hold harmless the Buyer from, any claim made against the Buyer by
any person for any such conversion, fee or other compensation.

          (n) Absence of Rights Agreement. The Company has not adopted a
shareholder rights plan or similar arrangement relating to accumulations of
beneficial ownership of Common Stock or a change in control of the Company.

     5. Certain Covenants and Acknowledgments.

          (a) Transfer Restrictions. The Buyer acknowledges that (i) the
Preferred Shares and Warrants have not been and are not being registered under
the provisions of the 1933 Act, and the Option Shares and the Additional
Warrants will not be registered under the

                                      -10-
<PAGE>
provisions of the 1933 Act, and, except as provided in the Registration Rights
Agreement, the Common Shares have not been and are not being registered under
the 1933 Act, and may not be transferred unless (a) subsequently registered
thereunder or (b) the Buyer shall have delivered to the Company an opinion of
counsel, reasonably satisfactory in form, scope and substance to the Company, to
the effect that the Securities to be sold or transferred may be sold or
transferred pursuant to an exemption from such registration; (ii) any sale of
the Securities made in reliance on Rule 144 promulgated under the 1933 Act may
be made only in accordance with the terms of said Rule and further, if said Rule
is not applicable, any such resale of Securities under circumstances in which
the seller, or the person through whom the sale is made, may be deemed to be an
underwriter, as that term is used in the 1933 Act, may require compliance with
some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (iii) neither the Company nor any other person is under any
obligation to register the Securities (other than pursuant to the Registration
Rights Agreement) under the 1933 Act or to comply with the terms and conditions
of any exemption thereunder (other than pursuant to Section 5(d) hereof and
pursuant to the Registration Rights Agreement).

          (b) Restrictive Legend.

               (1) The Buyer acknowledges and agrees that the certificates for
the Preferred Shares, Option Shares, Warrants, and the Additional Warrants and,
until such time as the Common Shares have been registered under the 1933 Act as
contemplated by the Registration Rights Agreement, the certificates for the
Common Shares issued upon conversion of the Preferred Shares and Option Shares
and exercise of the Warrants and the Additional Warrants may bear a restrictive
legend in substantially the following form (and a stop-transfer order may be
placed against transfer of the certificates for such Securities):

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE
          SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
          SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
          REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL
          THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

     Once the Registration Statement required to be filed by the Company
     pursuant to Section 2 of the Registration Rights Agreement has been
     declared effective, thereafter (i) upon request of the Buyer the Company
     will substitute certificates without this restrictive legend for
     certificates for any Common Shares issued prior to the date such
     Registration Statement is declared effective by the SEC which bear such
     restrictive legend and remove any stop-transfer restriction relating
     thereto promptly, but in no

                                      -11-
<PAGE>
     event later than three Business Days after surrender of such certificates
     by the Buyer and (ii) the Company shall not place any restrictive legend on
     certificates for Common Shares issued on conversion of the Preferred Shares
     or Option Shares or for Warrant Shares issued upon exercise of the Warrants
     or the Additional Warrants or impose any stop-transfer restriction thereon
     except as permitted under the Registration Rights Agreement.

               (2) The Buyer further acknowledges and agrees that the
certificates for the Preferred Shares and Option Shares may bear the following
additional identifying and restrictive legends in substantially the following
form:

          WITH REFERENCE TO THE STATEMENT OR RIGHTS AND PREFERENCES OF
          THE SERIES B CONVERTIBLE PREFERRED STOCK (THE "STATEMENT OF
          RIGHTS") PURSUANT TO WHICH THE SECURITIES REPRESENTED BY
          THIS CERTIFICATE WERE ISSUED, THE PORTION OF THE MAXIMUM
          SHARE AMOUNT (AS DEFINED IN SECTION 4(a)(1) OF THE STATEMENT
          OF RIGHTS) ALLOCATED TO THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE FOR PURPOSES OF CONVERSION THEREOF IS 609,375
          SHARES OR SUCH GREATER NUMBER AS PERMITTED BY THE RULES OF
          THE NASDAQ.

          SECTION 7(c)(3) OF THE STATEMENT OF RIGHTS PERMITS A HOLDER
          OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE TO CONVERT
          SUCH SECURITIES IN ACCORDANCE WITH THE STATEMENT OF RIGHTS
          WITHOUT BEING REQUIRED TO PHYSICALLY SURRENDER THIS
          CERTIFICATE TO THE COMPANY UNLESS ALL OF THE SECURITIES
          REPRESENTED HEREBY ARE SO CONVERTED. CONSEQUENTLY, FOLLOWING
          CONVERSION OF ANY OF THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE, THE NUMBER OF SHARES REPRESENTED BY THIS
          CERTIFICATE MAY BE LESS THAN THE NUMBER OF SHARES STATED
          HEREON.

          THE ISSUANCE DATE (AS DEFINED IN SECTION 7(b) OF THE
          STATEMENT OF RIGHTS) OF THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE IS [JUNE 30, 1998] [THE OPTION CLOSING DATE].

                                 -12-
<PAGE>
          (c) Registration Rights Agreement. The parties hereto agree to enter
into the Registration Rights Agreement on or before the Closing Date.

          (d) Form D. The Company agrees to file a Form D with the SEC with
respect to the Securities as required under Regulation D promulgated under the
1933 Act and to provide a copy thereof to the Buyer promptly after such filing.
The Buyer agrees to cooperate with the Company in connection with such filing
and, upon request of the Company, to provide all information relating to the
Buyer reasonably required for such filing.

          (e) Authorization for Trading; Reporting Status. On or before the date
that is 30 days after the Closing Date, but in any event before the effective
date of the Registration Statement (as defined in the Registration Rights
Agreement), the Company shall file a listing application for the Common Shares
with the Nasdaq and shall provide evidence of such filing to the Buyer. From the
Closing Date until such time as the Registration Statement is no longer required
to be in effect, the Company shall file all reports required to be filed with
the SEC pursuant to Section 13 or 15(d) of the 1934 Act and the Company shall
not terminate its status as an issuer required to file reports under the 1934
Act even if the 1934 Act or the rules and regulations thereunder would permit
such termination.

          (f) Use of Proceeds. The Company does not own or have any present
intention of acquiring any "margin stock" as defined in Regulation G (12 C.F.R.
Part 207) of the Board of Governors of the Federal Reserve System ("margin
stock"). The proceeds of sale of the Preferred Shares and, if the Put Option is
exercised, the Option Shares will be used for general working capital purposes
and in the operation of the Company's business. None of such proceeds will be
used, directly or indirectly (i) to make any loan to or investment in any other
person or (ii) for the purpose, whether immediate, incidental or ultimate, of
purchasing or carrying any margin stock or for the purpose of maintaining,
reducing or retiring any indebtedness which was originally incurred to purchase
or carry any stock that is currently a margin stock or for any other purpose
that might constitute the transactions contemplated by this Agreement as a
"purpose credit" within the meaning of such Regulation G. Neither the Company
nor any agent acting on its behalf has taken or will take any action which might
cause this Agreement or the transactions contemplated hereby to violate
Regulation G, Regulation T or any other regulation of the Board of Governors of
the Federal Reserve System or to violate the 1934 Act, in each case as in effect
now or as the same may hereafter be in effect.

          (g) Blue Sky Laws. On or before the Closing Date, the Company shall
take such action as shall be necessary to qualify, or to obtain an exemption
for, the Preferred Shares and Option Shares for sale to the Buyer pursuant to
this Agreement and the Common Shares for issuance to the Buyer on conversion of
the Preferred Shares and Option Shares, and exercise of the Warrants and the
Additional Warrants, under such of the securities or "blue sky" laws of
jurisdictions as shall be applicable to the sale of the Preferred Shares and

                                      -13-
<PAGE>
the Option Shares and the issuance of the Warrants and the Additional Warrants
pursuant to this Agreement and the issuance to the Buyer of Common Shares on
conversion of the Preferred Shares and Option Shares and exercise of the
Warrants and the Additional Warrants, or both. The Company shall furnish copies
of all filings, applications, orders and grants or confirmations of exemptions
relating to such securities or "blue sky" laws to the Buyer on or prior to the
Closing Date.

          (h) Certain Expenses and Fees. Whether or not the closing occurs, the
Company shall pay or reimburse the Buyer for all reasonable expenses (including,
without limitation, legal fees and expenses of counsel to the Buyer of up to
$15,000) incurred by the Buyer in connection with this Agreement and the
transactions contemplated hereby. Notwithstanding the foregoing, the Company
shall pay on demand all expenses (including reasonable attorneys' fees and
expenses) incurred by the Buyer, and the Buyer shall pay on demand all expenses
(including reasonable attorneys' fees and expenses) incurred by the Company, as
a consequence of, or in connection with, (1) any default or breach of any of the
other party's obligations under this Agreement, the Statement of Rights, the
Registration Rights Agreement, the Warrants, the Additional Warrants, and the
Transfer Agent Instructions (which payment shall be made by the defaulting or
breaching party), and (2) the enforcement or restructuring of any right of,
including the collection of any payments due, the Buyer or the Company, as the
case may be, under any of such agreements or instruments, including any action
or proceeding relating to such enforcement or any order, injunction or other
process seeking to restrain the Company or the Buyer, as the case may be, from
paying any amount due the Buyer or the Company, as the case may be, in which the
party seeking such enforcement or restructuring prevails.

          (i) Certain Issuances of Securities.

               (1) Unless the Company obtains Shareholder Approval (as defined
in Section 4(a)(7) of the Statement of Rights) or a waiver thereof from Nasdaq,
the Company will not issue any shares of Common Stock or shares of any other
series of preferred stock or other securities convertible into, exchangeable for
or otherwise entitling the holder to acquire shares of Common Stock which
issuance would be subject to the requirements of Rule 4460(i) of the Nasdaq (or
any successor or replacement provision thereof or any similar provision of any
other market on which the Common Stock is listed for trading) and which would be
integrated with the sale of the Preferred Shares and the Option Shares to the
Buyer or the issuance of Common Shares upon conversion thereof or upon exercise
of the Warrants and Additional Warrants for purposes of Rule 4460(i) (or any
successor or replacement provision thereof or any similar provision of any other
market on which the Common Stock is listed for trading).

               (2) The Company shall not offer, sell, contract to sell or issue
(or engage any person to assist the Company in taking any such action) any
equity securities or securities convertible into, exchangeable for or otherwise
entitling the holder to acquire, any

                                      -14-
<PAGE>
Common Stock (collectively, "Equity Securities") at a price below the market
price of the Common Stock (i) during the period from the Closing Date to the
date on which the Registration Statement shall have been effective with the SEC
for 60 consecutive days; and (ii) during the period from the date an Exercise
Notice is given by the Company to the Buyer to the date which is 60 days after
the Option Closing Date; provided, however, that nothing in this Section 5(i)(2)
shall prohibit the Company from issuing securities (x) pursuant to compensation
plans for employees, directors, officers, advisers or consultants of the Company
and in accordance with the terms of such plans as in effect as of the date of
this Agreement or (y) upon exercise of conversion, exchange, purchase or similar
rights issued, granted or given by the Company and outstanding as of the date of
this Agreement or pursuant to the exercise of the Warrants and the Additional
Warrants.

          (j) Best Efforts. Each of the parties shall use its best efforts
timely to satisfy each of the conditions to the other party's obligations to
sell and purchase the Preferred Shares set forth in Section 8 or 9, as the case
may be, of this Agreement on or before the Closing Date.

          (k) Certain Trading Restrictions. The Buyer agrees that, during the
period from the date the Registration Statement is first declared effective by
the SEC to the date of the conversion in full or redemption of all Preferred
Shares or Option Shares owned by the Buyer, the Buyer shall not engage in short
sales or other hedging transactions relating to the Common Stock, except that
the Buyer may enter into such transactions involving a number of shares of
Common Stock not to exceed the number of shares for which a Conversion Notice
(as defined in Section 6(b) herein) has been submitted to the Company and the
Transfer Agent (as defined in Section 6(a) herein) plus the number of shares
involved in such transactions which are permitted by the terms of the
Subscription Agreement, dated as of December 23, 1997, by and between the
Company and the Buyer, as such agreement may be amended from time to time (the
"1997 Subscription Agreement"). The Company and the Buyer further agree that, on
and after the Closing Date (in addition to the transactions permitted by the
preceding sentence) (i) the Buyer may engage in short sales or other hedging
transactions relating to up to one-half of the Warrant Shares or Warrants or the
Additional Warrants exercisable for up to one-half of the Warrant Shares,
provided that such transactions may only be effected at or above the last
reported sale price of the Common Stock in accordance with Rule 10a-1 under the
1934 Act, and (ii) the Buyer may engage in short sales and other hedging
transactions relating to the warrants issued pursuant to the 1997 Subscription
Agreement and the shares of Common Stock issued or issuable upon exercise
thereof in accordance with the terms of the 1997 Subscription Agreement.

     6. TRANSFER AGENT INSTRUCTIONS; CONVERSION PROCEDURE.

          (a) Transfer Agent Instructions. Prior to the Closing Date, the
Company will instruct ChaseMellon Shareholder Services, L.L.C., as Transfer
Agent and Registrar (the "Transfer Agent"), by letter in the form attached
hereto as Annex IV (the "Transfer

                                      -15-
<PAGE>
Agent Instructions"), to issue certificates for the Common Shares from time to
time on conversion of the Preferred Shares and exercise of the Warrants in such
amounts as specified from time to time to the Company in the Conversion Notices
and subscription form attached to the Warrants delivered in connection with such
conversions and exercises, as the case may be, and referred to in Sections 6(b)
and 6(c) of this Agreement. If the Company exercises the Put Option, prior to
the Option Closing Date the Company will provide an instruction in substantially
the same form to the Transfer Agent with respect to conversion of the Option
Shares and exercise of the Additional Warrants. The Common Shares shall be
registered in the name of the Buyer or its nominee and in such denominations to
be specified by the Buyer in connection with each conversion of Preferred Shares
and Option Shares and exercise of the Warrants and the Additional Warrants, as
the case may be. Such certificates may bear the restrictive legends specified in
Section 5(b) of this Agreement prior to registration of the resale of the Common
Shares under the 1933 Act. The Company warrants that no instructions other than
(x) such instructions referred to in this Section 6(a), (y) stop-transfer
instructions to give effect to Section 5(a) hereof prior to the registration of
the resale of the Common Shares under the 1933 Act, and (z) the instructions
required by Section 4(n) of the Registration Rights Agreement will be given by
the Company to the Transfer Agent and that the Common Shares otherwise shall be
freely transferable on the books and records of the Company as and to the extent
provided in this Agreement. Nothing in this Section 6(a) shall limit in any way
the Buyer's obligation and agreement to comply with all applicable securities
laws upon resale of the Shares. If the Buyer provides the Company with an
opinion of counsel reasonably satisfactory in form, scope, and substance to the
Company that registration of a resale by the Buyer of any of the Shares in
accordance with clause (i)(b) of Section 5(a) of this Agreement is not required
under the 1933 Act, the Company shall permit the transfer of such Shares and, in
the case of the Common Shares, promptly, but in no event later than three
Business Days after receipt of such opinion, instruct the Transfer Agent to
issue upon transfer one more share certificates in such name and such
denominations as specified by the Buyer. The provisions of Section 4(n) of the
Registration Rights Agreement shall be in addition to this Section 6(a) once
said Section 4(n) becomes applicable.

          (b) Conversion Procedure. In connection with the exercise of
conversion rights relating to the Preferred Shares and the Option Shares, the
Buyer or any subsequent holder of the Preferred Shares or the Option Shares
shall complete, sign and furnish to the Company, with a copy to the Transfer
Agent, a Notice of Conversion in the form attached hereto as Annex V, which
shall be deemed to satisfy all requirements of the Statement of Rights (a
"Conversion Notice"). As set forth in Section 7(c)(3) of the Statement of
Rights, the number of Common Shares to be issued in connection with a particular
conversion of Preferred Shares or Option Shares is, absent manifest error,
conclusively the number of Common Shares stated in the applicable Conversion
Notice. If in connection with a particular conversion of Preferred Shares or
Option Shares the Company determines that manifest error has been made by virtue
of the conversion price or other information set forth in the applicable
Conversion Notice, the Company shall have the right immediately to notify the
converting holder of such error (with a copy of such notice given to the
Transfer Agent

                                      -16-
<PAGE>
by facsimile), which notice shall state the number of Common Shares in dispute,
and, notwithstanding such notice from the Company, shall direct the Transfer
Agent to issue and deliver the number of Common Shares not in dispute as and
when required by the Statement of Rights. If the Company shall have notified the
Transfer Agent of any such error, the Company shall, on the date such notice is
given, submit the dispute to Deloitte & Touche LLP or another firm of
independent public accountants of recognized national standing (the "Auditors")
for determination and shall instruct the Auditors to resolve such dispute and to
notify the Company, the Transfer Agent, and the converting holder of Preferred
Shares or Option Shares, as the case may be, within one Business Day after such
dispute is submitted to the Auditors. Immediately after receipt of timely notice
of the Auditors' determination, the Company shall instruct the Transfer Agent to
issue to the converting holder any additional Common Shares to which such holder
is entitled based on the determination of the Auditors. If the Auditors shall
fail to notify the Transfer Agent within three Business Days after the
applicable Conversion Notice is given to the Company and the Transfer Agent,
then the Company shall instruct the Transfer Agent to issue, within three
Business Days after receipt of the applicable Conversion Notice, to the
converting holder any additional Common Shares to which such holder is entitled
based on the applicable Conversion Notice. Such immediate action shall be taken
by the Company to assure that there shall be full compliance with the Company's
unqualified obligation that all Common Shares issuable on such conversion be
issued by the due date therefor as provided in the Statement of Rights.

          (c) Exercise Procedure. In connection with an exercise of the Warrants
or the Additional Warrants, the Buyer or any subsequent holder of the Warrants
or the Additional Warrants shall complete, sign and furnish to the Company, with
a copy to the Transfer Agent, a form of subscription in the form attached to the
Warrants and the Additional Warrants and (if not exercised pursuant to the net
issuance provisions thereof) a certified or bank check or wire transfer in an
amount equal to the aggregate Purchase Price (as such term is defined in the
Warrants and the Additional Warrants) for the number of shares of Common Stock
being purchased, which shall be deemed to comply with all requirements of the
Warrants and the Additional Warrants (a "Subscription Form").

     7. CLOSING DATE.

     The date and time of the issuance and sale of the Preferred Shares and the
issuance of the Warrants (the "Closing Date") shall be 12:00 noon, New York City

are being offered and sold, the Warrants are being issued, and the Common Shares

requirements of United States federal and state securities laws and that the
Company is relying upon the truth and accuracy of, and the Buyer's compliance
with, the representations, warranties, agreements, acknowledgments and
understandings of the Buyer set forth herein in order to determine the
availability of such exemptions and the eligibility of the Buyer to acquire the
Preferred Shares and Warrants and to receive an offer of the Common Shares.

          (e) Information Provided. The Buyer and its advisors, if any, have
been furnished with all materials relating to the business, finances and
operations of the Company and materials relating to the offer and sale of the
Preferred Shares and Warrants and the offer of the Common Shares which have been

Company's (i) Annual Report on Form 10-K for the fiscal year ended December 31,
1997; (ii) the Quarterly Report on Form 10-Q for the fiscal quarter ended March
31, 1998; and (iii) the proxy statement for the Company's 1998 Annual Meeting

     3. COMPANY REPRESENTATIONS AND WARRANTIES.

     The Company represents and warrants to, and covenants and agrees with, the
Buyer that:

          (a) Organization and Authority. The Company is a corporation duly
organized and validly existing under the laws of the State of Washington, and
has all requisite corporate power and authority (i) to own, lease and operate
its properties and to carry on its business as now being conducted, and (ii) to
execute, deliver and perform its obligations under this Agreement, the
Registration Rights Agreement, the Statement of Rights, the Warrants, and the
other agreements to be executed and delivered by the Company in connection
herewith, and to consummate the transactions contemplated hereby and thereby.
The Company is duly qualified to do business as a foreign corporation and is in
good standing in all jurisdictions wherein such qualification is necessary and
where failure so to qualify could have a material adverse effect on the
business, properties, operations, condition (financial or other), results of
operations or prospects of the Company. The Company has no subsidiaries.

          (b) Capitalization. The authorized capital stock of the Company
currently consists of (a) 25,000,000 shares of Common Stock, of which 12,188,775
shares were outstanding as of June 29, 1998, all of which are fully paid and
nonassessable; and (b) 5,000,000 shares of Preferred Stock, $.01 par value, of
which (i) 10,000 shares are designated as Series A Convertible Preferred Stock,
of which 5,890 shares are outstanding; (ii) 12,000 shares will be designated as
Series B Convertible Preferred Stock prior to the Closing Date; and (iii) 5,000
shares are designated as Series C Convertible Preferred Stock, none of which are
outstanding. As of June 29, 1998, the Company had outstanding options entitling
the holders thereof to purchase 2,071,213 shares of Common Stock and outstanding
warrants entitling the holders thereof to purchase 782,196 shares of Common
Stock. As of the Closing Date, there will have been no material increase from
June 29, 1998 in the number of shares of Common Stock outstanding other than
pursuant to the exercise of outstanding options or warrants or the conversion of
outstanding shares of Series A Stock or both. The Company does not have
outstanding any material amount of securities (or obligations to issue any such
securities) convertible into, exchangeable for or otherwise entitling the
holders thereof to acquire shares of Common Stock, except as disclosed above or
in the Disclosure Documents or as set forth in Section 4(b) of the disclosure
letter delivered to the Buyer at or before the execution of this Agreement (the
"Disclosure Letter"). The outstanding shares of Common Stock and outstanding
options, warrants, and other securities to purchase Common Stock have been duly
authorized and validly issued. None of such outstanding shares of Common Stock,
options, warrants, and other securities has been issued in violation of the
preemptive rights of any security holder of the Company. The offers and sales of
the outstanding shares of Common Stock and options, warrants and other rights to
acquire Common Stock were at all relevant times either registered under the 1933
Act and applicable state securities laws or exempt from such requirements. No
holder

                                       -4-
<PAGE>
of any of the Company's securities has any rights, "demand," "piggy-back" or
otherwise, to have such securities registered by reason of the intention to
file, filing or effectiveness of the Registration Statement (as defined in the
Registration Rights Agreement), except for Advantage Fund II Ltd. and Genesee
Fund Limited - Portfolio B and as set forth in Section 4(b) of the Disclosure
Letter.

          (c) Concerning the Securities. The Securities have been duly
authorized and the Preferred Shares, when issued and paid for in accordance with
this Agreement, and the Common Shares, when issued upon conversion of the
Preferred Shares or in payment of dividends thereon or upon exercise of the
Warrants, as the case may be, will be duly and validly issued, fully paid and
non-assessable, and will not subject the holder thereof to personal liability by
reason of being such holder. There are no preemptive or similar rights of any
security holder of the Company or any other person to acquire any of the Shares.

and, except as set forth in Section 4(c) of the Disclosure Letter, (i) the
Company and the Common Stock meet the currently applicable criteria for
continued listing and trading on Nasdaq; (ii) the Company has not been notified
since September 25, 1995, by Nasdaq of any failure or potential failure to meet
the criteria for continued listing and trading on Nasdaq; (iii) no suspension of
trading in the Common Stock is in effect; and (iv) the Company knows of no
reason that the Common Shares will not be eligible for listing on Nasdaq.

in accordance with their respective terms, subject as to enforceability to
general principles of equity and to bankruptcy, insolvency, moratorium and other
similar laws affecting the enforcement of creditors' rights generally and limits
upon rights to indemnity.

          (e) Non-contravention. The execution and delivery of this Agreement by
the Company and the consummation by the Company of the issuance of the Preferred
Shares and the Warrants, as contemplated by this Agreement and completion of the
other transactions contemplated by this Agreement, the Registration Rights
Agreement and the terms of the Preferred Stock and the Warrants do not and will
not conflict with or result in a breach by the Company of any of the terms or
provisions of, or constitute a default under, the Restated Articles of
Incorporation or Bylaws of the Company, or any indenture, mortgage, deed of
trust or other material agreement or instrument to which the Company is a party
or by which it or any of its properties or assets are bound which would have a
material adverse effect on the Company or any applicable law, rule or regulation
or any applicable decree, judgment or order of any court, United States federal
or state regulatory body,

     4. Certain Covenants and Acknowledgments.

          (a) Transfer Restrictions. The Buyer acknowledges that (i) the
Preferred Shares and Warrants have not been and are not being registered under
the provisions of the 1933 Act and, except as provided in the Registration
Rights Agreement, the Common Shares have not been and are not being registered
under the 1933 Act, and may not be transferred unless (a) subsequently
registered thereunder or (b) the Buyer shall have delivered to the Company an
opinion of counsel, reasonably satisfactory in form, scope and substance to the
Company, to the effect that the Securities to be sold or transferred may be sold
or transferred pursuant to an exemption from such registration; (ii) any sale of
the Securities made in reliance on Rule 144 promulgated under the 1933 Act may
be made only in accordance with the terms of said Rule and further, if said Rule
is not applicable, any such resale of

                                       -7-
<PAGE>
Securities under circumstances in which the seller, or the person through whom
the sale is made, may be deemed to be an underwriter, as that term is used in
the 1933 Act, may require compliance with some other exemption under the 1933
Act or the rules and regulations of the SEC thereunder; and (iii) neither the
Company nor any other person is under any obligation to register the Securities
(other than pursuant to the Registration Rights Agreement) under the 1933 Act or
to comply with the terms and conditions of any exemption thereunder (other than
pursuant to Section 4(d) hereof and pursuant to the Registration Rights
Agreement).

          (b) Restrictive Legend.

               (1) The Buyer acknowledges and agrees that the certificates for
the Preferred Shares and the Warrants and, until such time as the Common Shares
have been registered under the 1933 Act as contemplated by the Registration
Rights Agreement, the certificates for the Common Shares issued upon conversion
of the Preferred Shares and exercise of the Warrants may bear a restrictive
legend in substantially the following form (and a stop-transfer order may be
placed against transfer of the certificates for such Securities):

          THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE
          SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE
          SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
          REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL
          THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

     Once the Registration Statement required to be filed by the Company
     pursuant to Section 2 of the Registration Rights Agreement has been
     declared effective, thereafter (i) upon request of the Buyer the Company
     will substitute certificates without this restrictive legend for
     certificates for any Common Shares issued prior to the date such
     Registration Statement is declared effective by the SEC which bear such
     restrictive legend and remove any stop-transfer restriction relating
     thereto promptly, but in no event later than three Business Days after
     surrender of such certificates by the Buyer and (ii) the Company shall not
     place any restrictive legend on certificates for Common Shares issued on
     conversion of the Preferred Shares or for Warrant Shares issued upon
     exercise of the Warrants or impose any stop-transfer restriction thereon
     except as permitted under the Registration Rights Agreement.

<PAGE>
               (2) The Buyer further acknowledges and agrees that the
certificates for the Preferred Shares may bear the following additional
identifying and restrictive legends in substantially the following form:

          WITH REFERENCE TO THE STATEMENT OR RIGHTS AND PREFERENCES OF
          THE SERIES B CONVERTIBLE PREFERRED STOCK (THE "STATEMENT OF
          RIGHTS") PURSUANT TO WHICH THE SECURITIES REPRESENTED BY
          THIS CERTIFICATE WERE ISSUED, THE PORTION OF THE MAXIMUM
          SHARE AMOUNT (AS DEFINED IN SECTION 4(a)(1) OF THE STATEMENT
          OF RIGHTS) ALLOCATED TO THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE FOR PURPOSES OF CONVERSION THEREOF IS 609,375
          SHARES OR SUCH GREATER NUMBER AS PERMITTED BY THE RULES OF
          THE NASDAQ.

          SECTION 7(c)(3) OF THE STATEMENT OF RIGHTS PERMITS A HOLDER
          OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE TO CONVERT
          SUCH SECURITIES IN ACCORDANCE WITH THE STATEMENT OF RIGHTS
          WITHOUT BEING REQUIRED TO PHYSICALLY SURRENDER THIS
          CERTIFICATE TO THE COMPANY UNLESS ALL OF THE SECURITIES
          REPRESENTED HEREBY ARE SO CONVERTED. CONSEQUENTLY, FOLLOWING
          CONVERSION OF ANY OF THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE, THE NUMBER OF SHARES REPRESENTED BY THIS
          CERTIFICATE MAY BE LESS THAN THE NUMBER OF SHARES STATED
          HEREON.

          THE ISSUANCE DATE (AS DEFINED IN SECTION 7(b) OF THE
          STATEMENT OF RIGHTS) OF THE SECURITIES REPRESENTED BY THIS
          CERTIFICATE IS JUNE 30, 1998.

          (c) Registration Rights Agreement. The parties hereto agree to enter
into the Registration Rights Agreement on or before the Closing Date.

          (d) Form D. The Company agrees to file a Form D with the SEC with
respect to the Securities as required under Regulation D promulgated under the
1933 Act and to provide a copy thereof to the Buyer promptly after such filing.
The Buyer agrees to cooperate with the Company in connection with such filing
and, upon request of the

                                       -9-
<PAGE>
Company, to provide all information relating to the Buyer reasonably required
for such filing.

          (e) Authorization for Trading; Reporting Status. On or before the date
that is 30 days after the Closing Date, but in any event before the effective
date of the Registration Statement (as defined in the Registration Rights
Agreement), the Company shall file a listing application for the Common Shares
with the Nasdaq and shall provide evidence of such filing to the Buyer. From the
Closing Date until such time as the Registration Statement is no longer required
to be in effect, the Company shall file all reports required to be filed with
the SEC pursuant to Section 13 or 15(d) of the 1934 Act and the Company shall
not terminate its status as an issuer required to file reports under the 1934
Act even if the 1934 Act or the rules and regulations thereunder would permit
such termination.

          (f) Use of Proceeds. The Company does not own or have any present
intention of acquiring any "margin stock" as defined in Regulation G (12 C.F.R.
Part 207) of the Board of Governors of the Federal Reserve System ("margin
stock"). The proceeds of sale of the Preferred Shares will be used for general
working capital purposes and in the operation of the Company's business. None of
such proceeds will be used, directly or indirectly (i) to make any loan to or
investment in any other person or (ii) for the purpose, whether immediate,
incidental or ultimate, of purchasing or carrying any margin stock or for the
purpose of maintaining, reducing or retiring any indebtedness which was
originally incurred to purchase or carry any stock that is currently a margin
stock or for any other purpose that might constitute the transactions
contemplated by this Agreement as a "purpose credit" within the meaning of such
Regulation G. Neither the Company nor any agent acting on its behalf has taken
or will take any action which might cause this Agreement or the transactions
contemplated hereby to violate Regulation G, Regulation T or any other
regulation of the Board of Governors of the Federal Reserve System or to violate
the 1934 Act, in each case as in effect now or as the same may hereafter be in
effect.

          (g) Blue Sky Laws. On or before the Closing Date, the Company shall
take such action as shall be necessary to qualify, or to obtain an exemption
for, the Preferred Shares for sale to the Buyer pursuant to this Agreement and
the Common Shares for issuance to the Buyer on conversion of the Preferred
Shares, and exercise of the Warrants, under such of the securities or "blue sky"
laws of jurisdictions as shall be applicable to the sale of the Preferred Shares
and the issuance of the Warrants pursuant to this Agreement and the issuance to
the Buyer of Common Shares on conversion of the Preferred Shares and exercise of
the Warrants, or both. The Company shall furnish copies of all filings,
applications, orders and grants or confirmations of exemptions relating to such
securities or "blue sky" laws to the Buyer on or prior to the Closing Date.

                                      -10-
<PAGE>
          (h) Certain Expenses and Fees. Whether or not the closing occurs, the
Company shall pay or reimburse the Buyer for all reasonable expenses (including,
without limitation, legal fees and expenses of counsel to the Buyer of up to
$15,000) incurred by the Buyer in connection with this Agreement and the
transactions contemplated hereby. Notwithstanding the foregoing, the Company
shall pay on demand all expenses (including reasonable attorneys' fees and
expenses) incurred by the Buyer, and the Buyer shall pay on demand all expenses
(including reasonable attorneys' fees and expenses) incurred by the Company, as
a consequence of, or in connection with, (1) any default or breach of any of the
other party's obligations under this Agreement, the Statement of Rights, the
Registration Rights Agreement, the Warrants, and the Transfer Agent Instructions
(which payment shall be made by the defaulting or breaching party), and (2) the
enforcement or restructuring of any right of, including the collection of any
payments due, the Buyer or the Company, as the case may be, under any of such
agreements or instruments, including any action or proceeding relating to such
enforcement or any order, injunction or other process seeking to restrain the
Company or the Buyer, as the case may be, from paying any amount due the Buyer
or the Company, as the case may be, in which the party seeking such enforcement
or restructuring prevails.

          (i) Certain Issuances of Securities.

               (1) Unless the Company obtains Shareholder Approval (as defined
in Section 4(a)(7) of the Statement of Rights) or a waiver thereof from Nasdaq,
the Company will not issue any shares of Common Stock or shares of any other
series of preferred stock or other securities convertible into, exchangeable for
or otherwise entitling the holder to acquire shares of Common Stock which
issuance would be subject to the requirements of Rule 4460(i) of the Nasdaq (or
any successor or replacement provision thereof or any similar provision of any
other market on which the Common Stock is listed for trading) and which would be
integrated with the sale of the Preferred Shares to the Buyer or the issuance of
Common Shares upon conversion thereof or upon exercise of the Warrants for
purposes of Rule 4460(i) (or any successor or replacement provision thereof or
any similar provision of any other market on which the Common Stock is listed
for trading).

               (2) The Company shall not offer, sell, contract to sell or issue
(or engage any person to assist the Company in taking any such action) any
equity securities or securities convertible into, exchangeable for or otherwise
entitling the holder to acquire, any Common Stock (collectively, "Equity
Securities") at a price below the market price of the Common Stock during the
period from the Closing Date to the date on which the Registration Statement
shall have been effective with the SEC for 60 consecutive days; provided,
however, that nothing in this Section 4(i)(2) shall prohibit the Company from
issuing securities (x) pursuant to compensation plans for employees, directors,
officers, advisers or consultants of the Company and in accordance with the
terms of such plans as in effect as of the date of this Agreement or (y) upon
exercise of conversion, exchange,

                                      -11-
<PAGE>
purchase or similar rights issued, granted or given by the Company and
outstanding as of the date of this Agreement or pursuant to the exercise of the
Warrants.

          (j) Best Efforts. Each of the parties shall use its best efforts
timely to satisfy each of the conditions to the other party's obligations to
sell and purchase the Preferred Shares set forth in Section 7 or 8, as the case
may be, of this Agreement on or before the Closing Date.

          (k) Certain Trading Restrictions. The Buyer agrees that, during the
period from the date the Registration Statement is first declared effective by
the SEC to the date of the conversion in full or redemption of all Preferred
Shares owned by the Buyer, the Buyer shall not engage in short sales or other
hedging transactions relating to the Common Stock, except that the Buyer may
enter into such transactions involving a number of shares of Common Stock not to
exceed the number of shares for which a Conversion Notice (as defined in Section
5(b) herein) has been submitted to the Company and the Transfer Agent (as
defined in Section 5(a) herein) plus the number of shares involved in such
transactions which are permitted by the terms of the Subscription Agreement,
dated as of December 23, 1997, by and between the Company and the Buyer, as such
agreement may be amended from time to time (the "1997 Subscription Agreement").
The Company and the Buyer further agree that, on and after the Closing Date (in
addition to the transactions permitted by the preceding sentence) (i) the Buyer
may engage in short sales or other hedging transactions relating to up to
one-half of the Warrant Shares or Warrants exercisable for up to one-half of the
Warrant Shares, provided that such transactions may only be effected at or above
the last reported sale price of the Common Stock in accordance with Rule 10a-1
under the 1934 Act, and (ii) the Buyer may engage in short sales and other
hedging transactions relating to the warrants issued pursuant to the 1997
Subscription Agreement and the shares of Common Stock issued or issuable upon
exercise thereof in accordance with the terms of the 1997 Subscription
Agreement.

     5. TRANSFER AGENT INSTRUCTIONS; CONVERSION PROCEDURE.

          (a) Transfer Agent Instructions. Prior to the Closing Date, the
Company will instruct ChaseMellon Shareholder Services, L.L.C., as Transfer
Agent and Registrar (the "Transfer Agent"), by letter in the form attached
hereto as Annex IV (the "Transfer Agent Instructions"), to issue certificates
for the Common Shares from time to time on conversion of the Preferred Shares
and exercise of the Warrants in such amounts as specified from time to time to
the Company in the Conversion Notices and subscription form attached to the
Warrants delivered in connection with such conversions and exercises, as the
case may be, and referred to in Sections 5(b) and 5(c) of this Agreement. The
Common Shares shall be registered in the name of the Buyer or its nominee and in
such denominations to be specified by the Buyer in connection with each
conversion of Preferred Shares and exercise of the Warrants, as the case may be.
Such certificates may bear the restrictive legends specified in Section 4(b) of
this Agreement prior to registration of the resale of the Common

                                      -12-
<PAGE>
Shares under the 1933 Act. The Company warrants that no instructions other than
(x) such instructions referred to in this Section 5(a), (y) stop-transfer
instructions to give effect to Section 4(a) hereof prior to the registration of
the resale of the Common Shares under the 1933 Act, and (z) the instructions
required by Section 4(n) of the Registration Rights Agreement will be given by
the Company to the Transfer Agent and that the Common Shares otherwise shall be
freely transferable on the books and records of the Company as and to the extent
provided in this Agreement. Nothing in this Section 5(a) shall limit in any way
the Buyer's obligation and agreement to comply with all applicable securities
laws upon resale of the Shares. If the Buyer provides the Company with an
opinion of counsel reasonably satisfactory in form, scope, and substance to the
Company that registration of a resale by the Buyer of any of the Shares in
accordance with clause (i)(b) of Section 4(a) of this Agreement is not required
under the 1933 Act, the Company shall permit the transfer of such Shares and, in
the case of the Common Shares, promptly, but in no event later than three
Business Days after receipt of such opinion, instruct the Transfer Agent to
issue upon transfer one more share certificates in such name and such
denominations as specified by the Buyer. The provisions of Section 4(n) of the
Registration Rights Agreement shall be in addition to this Section 5(a) once
said Section 4(n) becomes applicable.

          (b) Conversion Procedure. In connection with the exercise of
conversion rights relating to the Preferred Shares, the Buyer or any subsequent
holder of the Preferred Shares shall complete, sign and furnish to the Company,
with a copy to the Transfer Agent, a Notice of Conversion in the form attached
hereto as Annex V, which shall be deemed to satisfy all requirements of the
Statement of Rights (a "Conversion Notice"). As set forth in Section 7(c)(3) of
the Statement of Rights, the number of Common Shares to be issued in connection
with a particular conversion of Preferred Shares is, absent manifest error,
conclusively the number of Common Shares stated in the applicable Conversion
Notice. If in connection with a particular conversion of Preferred Shares the
Company determines that manifest error has been made by virtue of the conversion
price or other information set forth in the applicable Conversion Notice, the
Company shall have the right immediately to notify the converting holder of such
error (with a copy of such notice given to the Transfer Agent by facsimile),
which notice shall state the number of Common Shares in dispute, and,
notwithstanding such notice from the Company, shall direct the Transfer Agent to
issue and deliver the number of Common Shares not in dispute as and when
required by the Statement of Rights. If the Company shall have notified the
Transfer Agent of any such error, the Company shall, on the date such notice is
given, submit the dispute to Deloitte & Touche LLP or another firm of
independent public accountants of recognized national standing (the "Auditors")
for determination and shall instruct the Auditors to resolve such dispute and to
notify the Company, the Transfer Agent, and the converting holder of Preferred
Shares, as the case may be, within one Business Day after such dispute is
submitted to the Auditors. Immediately after receipt of timely notice of the
Auditors' determination, the Company shall instruct the Transfer Agent to issue
to the converting holder any additional Common Shares to which such holder is
entitled based on the determination of the Auditors. If the Auditors shall fail
to notify the Transfer Agent within three Business Days after the applicable

                                      -13-
<PAGE>
Conversion Notice is given to the Company and the Transfer Agent, then the
Company shall instruct the Transfer Agent to issue, within three Business Days
after receipt of the applicable Conversion Notice, to the converting holder any
additional Common Shares to which such holder is entitled based on the
applicable Conversion Notice. Such immediate action shall be taken by the
Company to assure that there shall be full compliance with the Company's
unqualified obligation that all Common Shares issuable on such conversion be
issued by the due date therefor as provided in the Statement of Rights.

          (c) Exercise Procedure. In connection with an exercise of the
Warrants, the Buyer or any subsequent holder of the Warrants shall complete,
sign and furnish to the Company, with a copy to the Transfer Agent, a form of
subscription in the form attached to the Warrants and (if not exercised pursuant
to the net issuance provisions thereof) a certified or bank check or wire
transfer in an amount equal to the aggregate Purchase Price (as such term is
defined in the Warrants) for the number of shares of Common Stock being
purchased, which shall be deemed to comply with all requirements of the Warrants
(a "Subscription Form").

     6. CLOSING DATE.

     The date and time of the issuance and sale of the Preferred Shares and the
issuance of the Warrants (the "Closing Date") shall be 12:00 noon, New York City
time, on the date which is (i) the date specified in Section 1(c) hereof, if
applicable, or (ii) such other mutually agreed to date and time. The closing
shall occur on the Closing Date at a location mutually agreed to by the parties
hereto.

     7.   CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL AND ISSUE.

the Warrants, the Buyer shall have the right to assign all of its rights and
obligations under this Agreement with respect to the purchase of all or any

obligations of the Buyer hereunder with respect to the purchase of the portion
of the Preferred Shares and the acquisition of the Warrants so assigned and

agreements of the Buyer and the Company contained in this Agreement or made by

by or on behalf of them or any person controlling or advising any of them.

          (j) This Agreement and its Annexes set forth the entire agreement
between the parties hereto with respect to the subject matter hereof and
supersede all prior agreements and understandings, whether written or oral, with
respect thereto.

          (k) The Buyer shall have the right to terminate this Agreement by
giving notice to the Company at any time at or prior to the Closing Date if:

               (1) the Company shall have failed, refused, or been unable at or
prior to the date of such termination of this Agreement to perform any of its
obligations hereunder;

               (2) any other condition of the Buyer's obligations hereunder is
not fulfilled; or

               (3) the closing shall not have occurred on or before June 30,
1998, other than solely by reason of a breach of this Agreement by the Buyer.

                                      -17-

Any such termination shall be effective upon the giving of notice thereof by the
Buyer. Upon such termination, the Buyer shall have no further obligation to the
Company hereunder and the Company shall remain liable for any breach of this
Agreement or the other documents contemplated hereby which occurred on or prior
to the date of such termination.

     2. Mandatory Registration for Resale.

          (a) The Company shall prepare and, on or before July 31, 1998, file
with the SEC a Registration Statement on Form S-3, which on the SEC Filing Date
covers the resale of a number of shares of Common Stock equal to at least the
number of Conversion Shares and Warrant Shares issuable to the Investor upon
conversion of the Preferred Shares and the Option Shares and exercise of the
Warrants and the Additional Warrants, determined as if the Preferred Shares and
the Option Shares were converted in full and the Warrants and the Additional
Warrants were exercised in full on the SEC Filing Date (determined without
regard to the limitation contained in the second sentence of Section 7(a) of the
Statement of Rights and the limitation contained in Section 1.1(b) of the
Warrants), and which Registration Statement shall state that, in accordance with
Rule 416 under the Securities Act, such Registration Statement also covers such
indeterminate number of additional shares of Common Stock as may become issuable
upon conversion of the Preferred Shares and the Option Shares and exercise of
the Warrants and the Additional Warrants to prevent dilution resulting from
stock splits, stock dividends or similar transactions, including by reason of
changes in the conversion price of the Preferred Shares and the Option Shares
and the exercise price of the Warrants and the Additional Warrants in accordance
with the respective terms thereof. The Registration Statement shall also cover
the resale of shares of Common Stock issuable to the holder of 3,000 shares of
Series B Convertible Preferred Stock and warrants to purchase 50,000 shares of
Common Stock which shares are required to be registered by the Company pursuant
to an agreement dated the date hereof in substantially the form of this
Agreement. If at any time the number of shares of Common Stock included in the
Registration Statement required to be filed as provided in the first sentence of
this Section 2(a) shall be insufficient to cover the number of shares of Common
Stock issuable on conversion in full of the unconverted Preferred Shares or
Option Shares and upon exercise of unexercised Warrants or Additional Warrants,
then promptly, but in no event later than 20 days after such insufficiency shall
occur, the Company shall file with the SEC an additional Registration Statement
on Form S-3 (which shall not constitute a post-effective amendment to the
Registration Statement filed pursuant to the first sentence of this Section
2(a)) covering such number of shares of Common Stock as shall be sufficient to
permit such conversion and exercises. For all purposes of this Agreement such
additional Registration Statement shall be deemed to be the Registration
Statement required to be filed by the Company pursuant to Section 2(a) of this
Agreement, and the Company and the Investors shall have the same rights and
obligations with respect to such additional Registration Statement as they shall
have with respect to the initial Registration Statement required to be filed by
the Company pursuant to this Section 2(a).

                                       -3-
<PAGE>
          (b) If any offering pursuant to a Registration Statement under Section
2(a) hereof involves an underwritten offering, the Investors who hold a majority
in interest of the Registrable Securities subject to such underwritten offering
shall have the right to select legal counsel and an investment banker or bankers
and manager or managers to administer the offering, which investment banker(s)
or manager(s) shall be reasonably satisfactory to the Company. The Investors who
hold the Registrable Securities to be included in such underwritten offering
shall pay all underwriting discounts and selling commissions and other fees and
expenses of such investment banker(s) and manager(s) (other than registration
expenses payable by the Company pursuant to Section 6 hereof) with respect to
their Registrable Securities and the fees and disbursements of such legal
counsel selected by the Investors.

          (c) If (i) the Company fails to file a Registration Statement with the
SEC on or before July 31, 1998, (ii) the Registration Statement covering the
Registrable Securities which is required to be filed by the Company pursuant to
the first sentence of Section 2(a) hereof is not effective within 90 days after
the Closing Date, (iii) the Company fails to submit a request for acceleration
of the effective date of the Registration Statement in accordance with Section
4(a), (iv) the Registration Statement required to be filed by the Company
pursuant to Section 2(a) shall cease to be available for use by any holder of
Preferred Shares or Option Shares which is named therein as a selling
shareholder for any reason (including, without limitation, by reason of an SEC
stop order, a material misstatement or omission in such Registration Statement
or the information contained in such Registration Statement having become
outdated) other than for an Excluded Period or for action caused by the selling
shareholder, including without limitation the attempt to sell securities other
than pursuant to the method of disposition described in the Registration
Statement, or (v) a holder of Preferred Shares or Option Shares has become
unable to convert any Preferred Shares or Option Shares in accordance with
Section (7)(a) of the Statement of Rights (other than by reason of the 4.9%
limitation set forth therein), then the Conversion Rate (as defined in the
Statement of Rights) shall be adjusted as provided in the Statement of Rights.

          (d) The Company, without the prior consent of the holders of a
majority in interest of the outstanding Preferred Shares and Option Shares, will
not file another registration statement with the SEC covering shares of the
Company's Common Stock prior to the effectiveness of the Registration Statement
described in Section 2(a), other than Registration Statements on Forms S-4 or
S-8.

          (e) The Company meets the requirements for the use of Form S-3 for
registration of the Registrable Securities for resale by the Investors. The
Company shall file all reports required to be filed by the Company with the SEC
in a timely manner so as to maintain such eligibility for the use of Form S-3.

     3. Company Registration and Underwritten Offering.

          (a) If at any time or from time to time the Company shall determine to
register any of its shares of Common Stock for its own account for offer and
sale in a firmly underwritten public offering, it shall (i) promptly give
written notice thereof to each Investor that owns of record any Registrable
Securities as of the date of such notice, and (ii) include in such registration
and underwritten offering all Registrable Securities requested to be so included
by any such Investor in a writing delivered to the Company within 20 days after
receipt of such written notice from the Company by the Investor, except as set
forth below.

          (b) Investors proposing to distribute all or a portion of their
Registrable Securities through such underwritten offering shall (together with
the Company and any other shareholders distributing their securities through
such underwritten offering) enter into an underwriting agreement in usual and
customary form with the managing underwriter(s) selected for such underwritten
offering by the Company. Notwithstanding any other provision of this Section 3,
if the managing underwriter determines that marketing factors require a
limitation of the number of shares to be underwritten, the managing underwriter
in its sole discretion may limit the number of Registrable Securities to be
included in the registration, or may exclude Registrable Securities entirely
from such registration. In such case, the Company shall so advise all Investors
whose Registrable Securities otherwise would be included in such registration,
and the number of shares of Registrable Securities that may be included in such
registration and underwritten offering shall be allocated among the Investors
requesting registration in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by each of such Investors at
the date of filing of the Registration Statement. If any Investor disapproves of
the terms and conditions of the underwritten offering, such Investor may
withdraw therefrom by written notice to the Company and the managing
underwriter(s). Any Registrable Securities excluded or withdrawn from such
underwritten offering shall be withdrawn from such registration.

          (c) Each Investor hereby agrees that, if requested by the Company and
the managing underwriter(s), it will enter into a customary form of "lock-up"
agreement with the Company and the managing underwriter(s) with respect to any
Registrable Securities then held by such Investor (other than those included in
the registration and underwritten offering described in this Section 3), which
agreement shall contain such terms and conditions no more restrictive on the
Investor's ability to sell or otherwise transfer such Registrable Securities
than those contained in any other such agreements then entered into by the
Company and the managing underwriter(s) with other comparable holders of the
Company's Common Stock.

                                       -5-
<PAGE>
          (d) Promptly following the expiration or termination of any such
lock-up agreement, the Company will take all reasonable steps, including filing
a Registration Statement in accordance with Section 2(a) hereof (or, in
accordance with Section 4(a) hereof, a post-effective amendment or supplement to
any Registration Statement and prospectus contained therein that previously was
filed in accordance with Section 2(a)), to enable Investors to sell their
remaining Registrable Securities free from restrictions under applicable
securities laws.

          (e) The Company shall have the right to terminate or withdraw any
registration initiated by the Company under this Section 3 prior to the
effectiveness of such registration whether or not any Investor has elected to
include Registrable Securities in such registration.

     4. Obligations of the Company. In connection with the registration of the
Registrable Securities pursuant to Sections 2 and 3 hereof, as applicable, the
Company shall:

          (a) prepare promptly, and file with the SEC not later than July 31,
1998, a Registration Statement with respect to the number of Registrable
Securities provided in Section 2(a), and thereafter use its best efforts to
cause each Registration Statement relating to Registrable Securities to become
effective as soon as possible after such filing, and keep the Registration
Statement effective pursuant to Rule 415 at all times until the earliest of (i)
such date as is three years after the date the Registration Statement is first
declared effective by the SEC, (ii) the date, on or after two years after the
later of the Closing Date and the Option Closing Date, if any, on which all of
Registrable Securities may be sold without regard to any requirement under the
Securities Act with respect to volume or manner of sale or the filing of any
notice relating thereto, and (iii) the date on which the Investors no longer
beneficially own any Registrable Securities (the period until such date, the
"Registration Period"); submit to the SEC, within five business days after the
Company learns that no review of the Registration Statement will be made by the
staff of the SEC or that the staff of the SEC has no further comments on the
Registration Statement, as the case may be, a request for acceleration of
effectiveness of the Registration Statement to a time and date not later than 48
hours after the delivery of such request; and the Company represents and
warrants to, and covenants and agrees with, the Investors that the Registration
Statement (including any amendments or supplements thereto and prospectuses
contained therein), at the time it is first filed with the SEC, at the time it
is ordered effective by the SEC and at all times during which it is required to
be effective hereunder (and each such amendment and supplement at the time it is
filed with the SEC and at all time during which it is available for use in
connection with the offer and sale of the Registrable Securities) shall not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein, or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading;

                                       -6-
<PAGE>
          (b) prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection therewith as may be necessary to keep such
Registration Statement effective at all times during the Registration Period,
and, during the Registration Period, comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Securities
covered by the Registration Statement until such time as all of such Registrable
Securities have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in the Registration
Statement;

          (c) furnish to each Investor whose Registrable Securities are included
in the Registration Statement and its legal counsel, (i) promptly after the same
is prepared and publicly distributed, filed with the SEC or received by the
Company, one copy of the Registration Statement and any amendment thereto, each
preliminary prospectus and prospectus and each amendment or supplement thereto,
each letter written by or on behalf of the Company to the SEC or the staff of
the SEC and each item of written correspondence from the SEC or the staff of the
SEC relating to such Registration Statement (other than any portion of any
thereof that contains information for which the Company has sought confidential
treatment) and (ii) such number of copies of a prospectus, including a
preliminary prospectus, and all amendments and supplements thereto and such
other documents, as such Investor may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by such Investor;

          (d) use reasonable efforts to (i) register and qualify the Registrable
Securities covered by the Registration Statement under such securities or blue
sky laws of such jurisdictions as the Investors who hold a majority in interest
of the Registrable Securities being offered reasonably request, (ii) prepare and
file in those jurisdictions such amendments (including post-effective
amendments) and supplements to such registrations and qualifications as may be
necessary to maintain the effectiveness thereof at all times during the
Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto (I) to qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 4(d), (II) to subject itself to general taxation in any such
jurisdiction, (III) to file a general consent to service of process in any such
jurisdiction, (IV) to provide any undertakings that cause more than nominal
expense or burden to the Company or (V) to make any change in its articles or
by-laws, which in each case the Board of Directors of the Company determines to
be contrary to the best interests of the Company and its shareholders;

                                       -7-
<PAGE>
          (e) in the event that the Registrable Securities are being offered in
an underwritten offering, enter into and perform its obligations under an
underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
underwriters of such offering;

          (f) as promptly as practicable after becoming aware of such event or
circumstance, notify each Investor of any event or circumstance of which the
Company has knowledge, as a result of which the prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and use its best efforts promptly to
prepare a supplement or amendment to the Registration Statement to correct such
untrue statement or omission, and deliver a number of copies of such supplement
or amendment to each Investor as such Investor may reasonably request. If such
event is the conduct of negotiations with respect to a transaction, the
disclosure of which the Company reasonably concludes would be detrimental to the
Company (each, a "Negotiation Event"), the Company shall be entitled, upon
giving notice of a Negotiation Event to each holder (the "Negotiation Notice")
and upon the reasonable determination of the Company, after consulting with
counsel, that failure to disclose the Negotiation Event would constitute an
omission to state a material fact required to be stated in the Registration
Statement, to require the Investors to suspend sales of the Common Stock
pursuant to the Registration Statement for a period of up to fifteen (15) days
after the giving of the Negotiation Notice; provided, however, that the Company
shall not give more than one (1) Negotiation Notice in any twelve-month period;

          (g) as promptly as practicable after becoming aware of such event,
notify each Investor who holds Registrable Securities being sold (or, in the
event of an underwritten offering, the managing underwriters) of the issuance by
the SEC of any stop order or other suspension of effectiveness of the
Registration Statement at the earliest possible time;

          (h) permit a single firm of counsel designated as selling
shareholders' counsel by the Investors who hold a majority in interest of the
Registrable Securities being sold to review and comment on the Registration
Statement and all amendments and supplements thereto a reasonable period of time
prior to their filing with the SEC, provided, that to the extent that the
failure of such counsel to respond promptly hereunder results in a delay in the
filing of the registration statement beyond July 31, 1998 or results in the
delay in the effective date thereof beyond the 90-day period specified in
Section 2(c)(ii), the July 31, 1998 filing deadline specified in Section 2(c)(i)
and the 90-day period specified in Section 2(c)(ii) shall be extended by the
amount of such resulting delay;

                                       -8-
<PAGE>
          (i) make generally available to its security holders as soon as
practical, but not later than 90 days after the close of the period covered
thereby, an earnings statement (in form complying with the provisions of Rule
158 under the Securities Act) covering a twelve-month period beginning not later
than the first day of the Company's fiscal quarter next following the effective
date of the Registration Statement;

          (j) at the request of the Investors who hold a majority in interest of
the Registrable Securities being sold, furnish on the date that Registrable
Securities are delivered to an underwriter, if any, for sale in connection with
the Registration Statement (i) a letter, dated such date, from the Company's
independent certified public accountants in form and substance as is customarily
given by independent certified public accountants to underwriters in
underwritten public offerings, addressed to the underwriters; and (ii) an
opinion, dated such date, from counsel representing the Company for purposes of
such Registration Statement, in form and substance as is customarily given in
underwritten public offerings, addressed to the underwriters and the Investors;

          (k) make available for inspection by any Investor, any underwriter
participating in any disposition pursuant to the Registration Statement and a
single firm of counsel and a single firm of accountants or other agents retained
by any such Investor and one firm of attorneys retained by all such underwriters
(collectively, the "Inspectors"), all pertinent financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records"), as shall be reasonably necessary to enable each Inspector to
exercise its due diligence responsibility, and cause the Company's officers,
directors and employees to supply all information that any Inspector reasonably
may request for purposes of such due diligence; provided, however, that each
Inspector shall hold in confidence and shall not make any disclosure (except to
an Investor) of any Record or other information which the Company determines in
good faith to be confidential, and of which determination the Inspectors are so
notified, unless (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in any Registration Statement, (ii) the
release of such Records is ordered pursuant to a subpoena or other order from a
court or government body of competent jurisdiction or (iii) the information in
such Records has been made generally available to the public other than by
disclosure in violation of this or any other agreement. The Company shall not be
required to disclose any confidential information in such Records to any
Inspector until and unless such Inspector shall have entered into
confidentiality agreements (in form and substance satisfactory to the Company)
with the Company with respect thereto, substantially in the form of this Section
4(k). Each Investor agrees that it shall, upon learning that disclosure of such
Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at the Company's own expense, to undertake appropriate action to
prevent disclosure of, or to obtain a protective order for, the Records deemed
confidential. The Company shall hold in confidence and shall not make any
disclosure of information concerning an Investor provided to the Company
pursuant to

                                       -9-
<PAGE>
Sections 5(a) and 5(e) hereof unless (i) disclosure of such information is
necessary to comply with federal or state securities laws, (ii) the disclosure
of such information is necessary to avoid or correct a misstatement or omission
in any Registration Statement, (iii) the release of such information is ordered
pursuant to a subpoena or other order from a court or governmental body of
competent jurisdiction or (iv) such information has been made generally
available to the public other than by disclosure in violation of this or any
other agreement. The Company agrees that it shall, upon learning that disclosure
of such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
notice to such Investor, at such Investor's own expense, to undertake
appropriate action to prevent disclosure of, or to obtain a protective order
for, such information;

          (l) use its best efforts (i) to cause all the Registrable Securities
covered by the Registration Statement to be listed on the Nasdaq National Market
(the "Nasdaq") or such other principal securities market on which securities of
the same class or series issued by the Company are then listed or traded or (ii)
if securities of the same class or series as the Registrable Securities are not
then listed on Nasdaq or any such other securities market, to cause all of the
Registrable Securities covered by the Registration Statement to be listed on the
New York Stock Exchange or the American Stock Exchange;

          (m) provide a transfer agent and registrar, which may be a single
entity, for the Registrable Securities not later than the effective date of the
Registration Statement;

          (n) cooperate with the Investors who hold Registrable Securities being
offered and the managing underwriter(s), if any, to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legends)
representing Registrable Securities to be offered pursuant to the Registration
Statement and enable such certificates to be in such denominations or amounts as
the case may be, as the managing underwriter(s), if any, or the Investors may
reasonably request and registered in such names as the managing underwriter(s),
if any, or the Investors may request; and, within three business days after a
Registration Statement which includes Registrable Securities is ordered
effective by the SEC, the Company shall deliver to the transfer agent for the
Registrable Securities (with copies to the Investors whose Registrable
Securities are included in such Registration Statement) an instruction
substantially in the form attached hereto as Exhibit 1 and shall deliver to the
Investors (with a copy to the Company's transfer agent) an opinion of its
general counsel, in the form attached hereto as Exhibit 2;

          (o) during the Registration Period the Company shall not bid for or
purchase any Common Stock or any right to purchase Common Stock or attempt to
induce any person to purchase any such security or right if such bid, purchase
or attempt would in any way limit the right of the Investors to sell Registrable
Securities by reason of the limitations in Regulation M under the Exchange Act;
and

                                      -10-
<PAGE>
          (p) take all other reasonable actions necessary to expedite and
facilitate disposition by the Investors of the Registrable Securities pursuant
to the Registration Statement.

     5. Obligations of the Investors. In connection with the registration of the
Registrable Securities, the Investors shall have the following obligations:

          (a) It shall be a condition precedent to the obligations of the
Company to complete the registration pursuant to this Agreement with respect to
the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the registration
of such Registrable Securities and shall execute such documents in connection
with such registration as the Company may reasonably request. At least four days
prior to the first anticipated filing date of the Registration Statement, the
Company shall notify each Investor of the information the Company requires from
each such Investor (the "Requested Information") if any of such Investor's
Registrable Securities are eligible for inclusion in the Registration Statement.
If at least one business day prior to the filing date the Company has not
received the Requested Information from an Investor (a "Non-Responsive
Investor"), then the Company may file the Registration Statement without
including Registrable Securities of such Non-Responsive Investor, but shall not
be relieved of its obligation to file a Registration Statement with the SEC
relating to the Registrable Securities of such Non-Responsive Investor promptly
after such Non-Responsive Investor provides the Requested Information;

          (b) Each Investor by such Investor's acceptance of the Registrable
Securities agrees to cooperate with the Company as reasonably requested thereby
in connection with the preparation and filing of the Registration Statement
hereunder, unless such Investor has notified the Company in writing of such
Investor's election to exclude all of such Investor's Registrable Securities
from the Registration Statement;

          (c) In the event Investors holding a majority in interest of the
Registrable Securities being registered determine to engage the services of an
underwriter, or if an Investor seeks to participate in a registration and
underwritten offering pursuant to Section 3 hereof, each Investor or each such
participating Investor, as the case may be, agrees to enter into and perform
such Investor's obligations under an underwriting agreement, in usual and
customary form, including, without limitation, customary indemnification and
contribution obligations, with the managing underwriter(s) of such offering and
take such other actions as are reasonably required in order to expedite or
facilitate the disposition of the Registrable Securities, unless such Investor
has notified the Company in writing of such Investor's

                                      -11-
<PAGE>
election to exclude all or a portion of such Investor's Registrable Securities
from the Registration Statement;

          (d) Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 4(f) or
4(g), such Investor will immediately discontinue disposition of Registrable
Securities pursuant to the Registration Statement covering such Registrable
Securities until such Investor's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 4(f) or 4(g) and, if so directed by
the Company, such Investor shall deliver to the Company (at the expense of the
Company) or destroy (and deliver to the Company a certificate of destruction)
all copies in such Investor's possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice;

          (e) No Investor may participate in any registration relating to an
underwritten offering hereunder unless such Investor (i) agrees to sell such
Investor's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Investors entitled hereunder to approve such
arrangements, with respect to an underwritten offering under Section 2 hereof,
or approved by the Company, with respect to an underwritten offering under
Section 3 hereof; (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements; and (iii) agrees to
pay its pro rata share of all underwriting discounts and selling commissions
(and, with respect to an underwritten offering pursuant to Section 2(b) hereof,
any other fees and expenses) of any investment banker(s) and manager(s) with
respect to its Registrable Securities sold in such offering and of the fees and
expenses of counsel selected by the Investors.

          (f) Each Investor agrees that during the period from the date the
Registration Statement is first declared effective by the SEC to the date of
conversion in full or redemption of all Preferred Shares and Option Shares owned
by the Investor, the Investor shall not engage in short sales or other hedging
transactions relating to the Common Stock, except that the Investor may enter
into such transactions involving a number of shares of Common Stock not to
exceed the number of shares for which a Conversion Notice has been submitted to
the Transfer Agent and the Company (it being understood that this Section 5(f)
shall not restrict such transactions which are otherwise permitted by the
Subscription Agreement or any other agreement between the Investor and the
Company).

          (g) Each Investor agrees that it will not effect any disposition of
the Registrable Securities except as contemplated in the Registration Statement
or as is otherwise in compliance with applicable securities laws and that it
will promptly notify the Company of any material change in the information set
forth in the Registration Statement regarding such Investor's plan of
distribution. Each Investor agrees (a) to notify the Company in writing in

                                      -12-
<PAGE>
the event that such Investor enters into any material agreement with a broker or
a dealer for the sale of the Registrable Securities through a block trade,
special offering or exchange distribution and (b) in connection with such
agreement, to provide to the Company in writing the information necessary to
enable the Company to prepare, at the Company's sole cost and expense, any
supplemental prospectus pursuant to Rule 424(c) under the Securities Act which
is required with respect to such transaction. In connection with any sale of
Registrable Securities which is made pursuant to the Registration Statement,
each Investor shall instruct its broker or brokers to deliver the prospectus to
the purchaser or purchasers in connection with such sale, shall supply copies of
such prospectus to such broker or brokers and shall otherwise use its reasonable
best efforts to comply with the prospectus delivery requirements of the
Securities Act.

     6. Expenses of Registration. All reasonable expenses incurred in effecting
any registration pursuant to this Agreement, including, without limitation, all
registration, listing, qualification, and filing fees, printing and accounting
expenses, fees and disbursements of counsel for the Company, shall be borne by
the Company (except as otherwise may be required under applicable state
securities or blue sky laws); provided, however, that the Investors shall pay
all (i) underwriting discounts and selling commissions (and, with respect to an
underwritten offering pursuant to Section 2(b) hereof, any other fees and
expenses) of any investment banker(s) and manager(s) applicable to the sale of
Registrable Securities in an underwritten offering and (ii) fees and
disbursements of counsel to the Investors, in accordance with Sections 2(b) and
5(e) hereof.

     7. Indemnification. In the event any Registrable Securities are included in
a Registration Statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Investor who holds such Registrable Securities, the
directors, if any, of such Investor, the officers, if any, of such Investor,
each person, if any, who controls any Investor within the meaning of the
Securities Act or the Exchange Act, any underwriter (as defined in the
Securities Act) for the Investors, the directors, if any, of such underwriter
and the officers, if any, of such underwriter, and each person, if any, who
controls any such underwriter within the meaning of the Securities Act or the
Exchange Act (each, an "Indemnified Person"), against any losses, claims,
damages, liabilities or expenses (joint or several) incurred (collectively,
"Claims") to which any of them may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such Claims (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any of the following statements, omissions or violations in the
Registration Statement, or any post-effective amendment thereof, or any
prospectus included therein: (i) any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any
post-effective amendment thereof or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements

                                      -13-
<PAGE>
therein not misleading, (ii) any untrue statement or alleged untrue statement of
a material fact contained in any preliminary prospectus if used prior to the
effective date of such Registration Statement, or contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading or (iii) any violation or alleged violation by the Company
of the Securities Act, the Exchange Act, any state securities law or any rule or
regulation under the Securities Act, the Exchange Act or any state securities
law (the matters in the foregoing clauses (i) through (iii) being, collectively,
"Violations"). Subject to the restrictions set forth in Section 7(d) with
respect to the number of legal counsel, the Company shall reimburse the
Investors and each such underwriter or controlling person, promptly as such
expenses are incurred and are due and payable, for any legal fees or other
reasonable expenses incurred by them in connection with investigating or
defending any such Claim. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 7(a): (I) shall
not apply to a Claim arising out of or based upon a Violation which occurs in
reliance upon and in conformity with information furnished in writing to the
Company by any Indemnified Person or underwriter for such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto, if such
prospectus was timely made available by the Company pursuant to Section 4(c)
hereof; (II) with respect to any preliminary prospectus shall not inure to the
benefit of any such person from whom the person asserting any such Claim
purchased the Registrable Securities that are the subject thereof (or to the
benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus was corrected
in the prospectus, as then amended or supplemented, if such prospectus was
timely made available by the Company pursuant to Section 4(c) hereof; and (III)
shall not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnified
Person and shall survive the transfer of the Registrable Securities by the
Investors pursuant to Section 10.

          (b) In connection with any Registration Statement in which an Investor
is participating, each such Investor agrees to indemnify and hold harmless, to
the same extent and in the same manner set forth in Section 7(a), the Company,
each of its directors, each of its officers who signs the Registration
Statement, each person, if any, who controls the Company within the meaning of
the Securities Act or the Exchange Act, any underwriter and any other
shareholder selling securities pursuant to the Registration Statement or any of
its directors or officers or any person who controls such shareholder or
underwriter within the meaning of the Securities Act or the Exchange Act
(collectively and together with an Indemnified Person, an "Indemnified Party"),
against any Claim to which any of them may become subject, under the Securities
Act, the Exchange Act or otherwise, insofar as such

                                      -14-
<PAGE>
Claim arises out of or is based upon any Violation, in each case to the extent
(and only to the extent) that such Violation occurs in reliance upon and in
conformity with written information furnished to the Company by such Investor
expressly for use in connection with such Registration Statement; and such
Investor will reimburse any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such Claim; provided, however,
that the indemnity agreement contained in this Section 7(b) shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of such Investor, which consent shall not be
unreasonably withheld; provided, further, however, that the Investor shall be
liable under this Section 7(b) for only that amount of a Claim as does not
exceed the amount by which the net proceeds to such Investor from the sale of
Registrable Securities pursuant to such Registration Statement exceeds the cost
of such Registrable Securities to such Investor. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
such Indemnified Party and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 10. Notwithstanding anything to
the contrary contained herein, the indemnification agreement contained in this
Section 7(b) with respect to any preliminary prospectus shall not inure to the
benefit of any Indemnified Party if the untrue statement or omission of material
fact contained in the preliminary prospectus was corrected on a timely basis in
the prospectus, as then amended or supplemented.

          (c) The Company shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in any distribution, to the same extent as provided
above, with respect to information so furnished in writing by such persons
expressly for inclusion in the Registration Statement.

          (d) Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 7 of notice of the commencement of any action
(including any governmental action), such Indemnified Person or Indemnified
Party shall, if a Claim in respect thereof is to be made against any
indemnifying party under this Section 7, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel selected by the indemnifying party
but reasonably acceptable to the Indemnified Person or the Indemnified Party, as
the case may be; provided, however, that an Indemnified Person or Indemnified
Party shall have the right to retain its own counsel with the fees and expenses
to be paid by the indemnifying party, if, in the reasonable opinion of counsel
retained by the indemnifying party, the representation by such counsel of the
Indemnified Person or Indemnified Party and the indemnifying party would be
inappropriate due to actual or potential differing interests between such
Indemnified Person or Indemnified Party and any other party represented by such
counsel in such proceeding. In such event, the Company shall pay for only one
separate legal counsel for the Investors; such legal

                                      -15-
<PAGE>
counsel shall be selected by the Investors holding a majority in interest of the
Registrable Securities included in the Registration Statement to which the Claim
relates. The failure to deliver written notice to the indemnifying party within
a reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 7, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action. The indemnification required by
this Section 7 shall be made by periodic payments of the amount thereof during
the course of the investigation or defense, as such expense, loss, damage or
liability is incurred and is due and payable.

     8. Contribution. To the extent any indemnification by an indemnifying party
is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 7 to the fullest extent permitted by law; provided,
however, that (a) no contribution shall be made under circumstances where the
maker would not have been liable for indemnification under the fault standards
set forth in Section 7, (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 12(f) of the
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation and (c)
contribution by a seller of Registrable Securities shall be limited in amount to
the amount by which the net amount of proceeds received by such seller from the
sale of such Registrable Securities exceeds the purchase price paid by such
seller for such Registrable Securities.

     9. Reports under Exchange Act. With a view to making available to the
Investors the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the
Investors to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

          (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

          (c) furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Exchange Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company and
(iii) such other information as may be reasonably requested to permit the
Investors to sell such securities pursuant to Rule 144 without registration.

                                      -16-
<PAGE>
     10. Assignment of the Registration Rights. The rights to have the Company
register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the Investors to any transferee who holds at least 20%
of the Registrable Securities (or Preferred Shares, Option Shares, Warrants, and
Additional Warrants convertible or exercisable into 20% of the Registrable
Securities) (or any equivalent combination of Preferred Shares, Option Shares,
Warrants, Additional Warrants, and Registrable Securities) only if: (a) the
Investor agrees in writing with the transferee or assignee to assign such
rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment; (b) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (i) the
name and address of such transferee or assignee and (ii) the securities with
respect to which such registration rights are being transferred or assigned; (c)
immediately following such transfer or assignment the further disposition of
such securities by the transferee or assignee is restricted under the Securities
Act and applicable state securities laws; (d) at or before the time the Company
received the written notice contemplated by clause (b) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; (e) such transfer shall have been made in
accordance with the applicable requirements of the Subscription Agreement; (f)
such transferee shall be an "Accredited Investor" as that term defined in Rule
501 of Regulation D promulgated under the Securities Act but shall not be a
broker-dealer or a member of the National Association of Securities Dealers,
Inc.; and (g) in the event the assignment occurs subsequent to the date of
effectiveness of the Registration Statement required to be filed pursuant to
Section 2(a) and the assignment is not made pursuant to Section 2(c) of the
Subscription Agreement, such assignee or transferee agrees to pay all reasonable
expenses of amending or supplementing such Registration Statement to reflect
such assignment. In connection with any such transfer the Company shall promptly
after such assignment take such actions as shall be reasonably acceptable to the
Initial Investor and such transferee to assure that the Registration Statement
and related prospectus are available for use by such transferee for sales of the
Registrable Securities in respect of which the rights to registration have been
so assigned.

     11. Amendment of Registration Rights. Any provision of this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors who hold or have the right to
acquire a majority in interest of the Registrable Securities. Any amendment or
waiver effected in accordance with this Section 11 shall be binding upon each
Investor and the Company.

                                      -17-

     12. Miscellaneous.

          (a) A person or entity is deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

          (b) Notices required or permitted to be given hereunder shall be in
writing and shall be deemed to be sufficiently given when personally delivered

if to any other Investor, at such address as such Investor shall have provided
in writing to the Company, or at such other address as each such party furnishes
by notice given in accordance with this Section 12(b), and shall be effective,
when personally delivered, upon receipt, and when sent by facsimile, upon
receipt of confirmation of successful transmission.

          (c) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

          (d) This Agreement shall be enforced, governed by and construed in
accordance with the laws of the State of Washington applicable to agreements
made and to be performed entirely within such State. In the event that any
provision of this Agreement is invalid or unenforceable under any applicable
statute or rule of law, then such provision shall be deemed inoperative to the
extent that it may conflict therewith and shall be deemed modified to conform
with such statute or rule of law. Any provision hereof which may prove invalid
or unenforceable under any law shall not affect the validity or enforceability
of any other provision hereof.

          (e) This Agreement constitutes the entire agreement among the parties
hereto with respect to the subject matter hereof. There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to
herein. This Agreement supersedes all prior agreements and understandings among
the parties hereto with respect to the subject matter hereof.

          (f) Subject to the requirements of Section 10 hereof, this Agreement
shall inure to the benefit of and be binding upon the successors and assigns of
each of the parties hereto.

feminine or neuter, singular or plural, as the context may require.

          (h) The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof.

          (i) The Company acknowledges that any failure by the Company to
perform its obligations under this Agreement, including, without limitation, the
Company's obligations under Section 4(n), or any delay in such performance could
result in damages to the Investors and the Company agrees that, in addition to
any other liability the Company may have by reason of any such failure or delay,
the Company shall be liable for all direct and consequential damages caused by
any such failure or delay; provided, however, that in no event shall the total
damages recoverable by the Investors for claims arising from or related to this
Agreement exceed 150% of the aggregate purchase price paid by the Initial
Investor to the Company for the Preferred Shares (and, if the Put Option is
exercised, the Option Shares), less all amounts received by the Investors from
market resales of shares of Common Stock as contemplated by this Agreement.

          (j) This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original but all of which shall constitute one and
the same agreement. This Agreement, once executed by a party, may be delivered
to the other party hereto by facsimile of a copy of this Agreement bearing the
signature of the party so delivering this Agreement.

To the Investors listed on Schedule A


ChaseMellon Shareholder Services, L.L.C.
   as Transfer Agent and Registrar
520 Pike Street, Suite 1220
Seattle, WA  98101


Ladies and Gentlemen:

     I am the general counsel of Tera Computer Company, a Washington corporation
(the "Company"), and I understand that [Name of Investor] (the "Holder") has
purchased from the Company an aggregate of ____________ shares (the "Preferred
Shares") of the Company's Series B Convertible Preferred Stock, $.01 par value
(the "Preferred Stock"), and acquired _________ Warrants (the "Warrants"). The
Preferred Shares were purchased and Warrants were acquired by the Holder
pursuant to a Subscription Agreement, dated as of June __, 1998, between the
Holder and the Company (the "Subscription Agreement"). Pursuant to a
Registration Rights Agreement, dated as of June __, 1998, between the Company
and the Holder (the "Registration Rights Agreement") entered into in connection
with the purchase by the Holder of the Preferred Shares, the Company agreed with
the Holder, among other things, to register for resale the shares of Common
Stock issuable upon conversion of the Preferred Shares and exercise of the
Warrants (the "Underlying Shares") under the Securities Act of 1933, as amended
(the "Securities Act"), upon the terms provided in the Registration Rights
Agreement. Pursuant to the Registration Rights Agreement, on __________, the
Company filed a Registration Statement on Form S-3 (File No. 333-__________)
(the "Registration Statement") with the Securities and Exchange Commission (the
"SEC") relating to the Underlying Shares, which names the Holder as a selling
shareholder thereunder.
<PAGE>
     I advise you that, on ________, 1998, a registration statement under the
Securities Act became effective with respect to the resale of the shares of
Common Stock underlying the shares of Preferred Stock and Warrants held by the
Holder. Therefore, I am of the opinion that the Underlying Shares may be resold
by the selling shareholders named in the Prospectus included in such
registration statement and the certificates evidencing the Underlying Shares
need not bear any Securities Act restrictive legend.


                                       Very truly yours,

                          REGISTRATION RIGHTS AGREEMENT


     THIS REGISTRATION RIGHTS AGREEMENT, dated as of June 30, 1998 (this
"Agreement"), is made by and between TERA COMPUTER COMPANY, a Washington
corporation (the "Company"), and the person named on the signature page hereto
(the "Initial Investor").

                              W I T N E S S E T H:

     WHEREAS, in connection with the Subscription Agreement, dated as of June

Underlying Shares (as defined in Section 1(a)(viii) below);

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein and other good and valuable consideration, the receipt and

Investor hereby agree as follows:

               (iii) "Investor" means the Initial Investor and any transferee or
     assignee who agrees to become bound by the provisions of this Agreement in
     accordance with Section 10 hereof.

               (iv) "Register," "registered," and "registration" refer to a
     registration effected by preparing and filing a Registration Statement or
     Statements in compliance with the Securities Act and pursuant to Rule 415
     under the Securities Act or any successor rule providing for offering
     securities on a continuous basis ("Rule 415"), and the declaration or
     ordering of effectiveness of such Registration Statement by the United
     States Securities and Exchange Commission (the "SEC").

               (v) "Registrable Securities" means the Underlying Shares and any
     shares of Common Stock issued by the Company to any Investor as a dividend
     on the Preferred Shares and as payment of any interest on accrued dividends
     in arrears.

               (vi) "Registration Statement" means a registration statement of
     the Company under the Securities Act, including any amendment thereto.

               (vii) "SEC Filing Date" means the date the Registration Statement

Capitalized terms used herein and not otherwise defined herein shall have the
respective meanings set forth in the Subscription Agreement, or, if applicable,
in the Statement of Rights and Preferences of the Series B Convertible Preferred
Stock and the Warrants.

     2. Mandatory Registration for Resale.

          (a) The Company shall prepare and, on or before July 31, 1998, file
with the SEC a Registration Statement on Form S-3, which on the SEC Filing Date
covers the

                                       -2-
<PAGE>
resale of a number of shares of Common Stock equal to at least the number of
Conversion Shares and Warrant Shares issuable to the Investor upon conversion of
the Preferred Shares and exercise of the Warrants, determined as if the
Preferred Shares were converted in full and the Warrants were exercised in full
on the SEC Filing Date (determined without regard to the limitation contained in
the second sentence of Section 7(a) of the Statement of Rights and the
limitation contained in Section 1.1(b) of the Warrants), and which Registration
Statement shall state that, in accordance with Rule 416 under the Securities
Act, such Registration Statement also covers such indeterminate number of
additional shares of Common Stock as may become issuable upon conversion of the
Preferred Shares and exercise of the Warrants to prevent dilution resulting from
stock splits, stock dividends or similar transactions, including by reason of
changes in the conversion price of the Preferred Shares and the exercise price
of the Warrants in accordance with the respective terms thereof. The
Registration Statement shall also cover the resale of shares of Common Stock
initially issuable or which may become issuable to Advantage Fund II Ltd. which
holds or may acquire an aggregate of up to 9,000 shares of Series B Convertible
Preferred Stock and warrants to purchase up to 150,000 shares of Common Stock
which shares are required to be registered by the Company pursuant to an
agreement dated the date hereof in substantially the form of this Agreement. If
at any time the number of shares of Common Stock included in the Registration
Statement required to be filed as provided in the first sentence of this Section
2(a) shall be insufficient to cover the number of shares of Common Stock
issuable on conversion in full of the unconverted Preferred Shares and upon
exercise of unexercised Warrants, then promptly, but in no event later than 20
days after such insufficiency shall occur, the Company shall file with the SEC
an additional Registration Statement on Form S-3 (which shall not constitute a
post-effective amendment to the Registration Statement filed pursuant to the
first sentence of this Section 2(a)) covering such number of shares of Common
Stock as shall be sufficient to permit such conversion and exercises. For all
purposes of this Agreement such additional Registration Statement shall be
deemed to be the Registration Statement required to be filed by the Company
pursuant to Section 2(a) of this Agreement, and the Company and the Investors
shall have the same rights and obligations with respect to such additional
Registration Statement as they shall have with respect to the initial
Registration Statement required to be filed by the Company pursuant to this
Section 2(a).

          (b) If any offering pursuant to a Registration Statement under Section
2(a) hereof involves an underwritten offering, the Investors who hold a majority
in interest of the Registrable Securities subject to such underwritten offering
shall have the right to select legal counsel and an investment banker or bankers
and manager or managers to administer the offering, which investment banker(s)
or manager(s) shall be reasonably satisfactory to the Company. The Investors who
hold the Registrable Securities to be included in such underwritten offering
shall pay all underwriting discounts and selling commissions and other fees and
expenses of such investment banker(s) and manager(s) (other than registration
expenses payable by the Company pursuant to Section 6 hereof) with respect to
their

                                       -3-
<PAGE>
Registrable Securities and the fees and disbursements of such legal counsel
selected by the Investors.

          (c) If (i) the Company fails to file a Registration Statement with the
SEC on or before July 31, 1998, (ii) the Registration Statement covering the
Registrable Securities which is required to be filed by the Company pursuant to
the first sentence of Section 2(a) hereof is not effective within 90 days after
the Closing Date, (iii) the Company fails to submit a request for acceleration
of the effective date of the Registration Statement in accordance with Section
4(a), (iv) the Registration Statement required to be filed by the Company
pursuant to Section 2(a) shall cease to be available for use by any holder of
Preferred Shares which is named therein as a selling shareholder for any reason
(including, without limitation, by reason of an SEC stop order, a material
misstatement or omission in such Registration Statement or the information
contained in such Registration Statement having become outdated) other than for
an Excluded Period or for action caused by the selling shareholder, including
without limitation the attempt to sell securities other than pursuant to the
method of disposition described in the Registration Statement, or (v) a holder
of Preferred Shares has become unable to convert any Preferred Shares in
accordance with Section (7)(a) of the Statement of Rights (other than by reason
of the 4.9% limitation set forth therein), then the Conversion Rate (as defined
in the Statement of Rights) shall be adjusted as provided in the Statement of
Rights.

          (d) The Company, without the prior consent of the holders of a
majority in interest of the outstanding Preferred Shares, will not file another
registration statement with the SEC covering shares of the Company's Common
Stock prior to the effectiveness of the Registration Statement described in
Section 2(a), other than Registration Statements on Forms S-4 or S-8.

          (e) The Company meets the requirements for the use of Form S-3 for
registration of the Registrable Securities for resale by the Investors. The
Company shall file all reports required to be filed by the Company with the SEC
in a timely manner so as to maintain such eligibility for the use of Form S-3.

     3. Company Registration and Underwritten Offering.

          (a) If at any time or from time to time the Company shall determine to
register any of its shares of Common Stock for its own account for offer and
sale in a firmly underwritten public offering, it shall (i) promptly give
written notice thereof to each Investor that owns of record any Registrable
Securities as of the date of such notice, and (ii) include in such registration
and underwritten offering all Registrable Securities requested to be so included
by any such Investor in a writing delivered to the Company within 20 days after
receipt of such written notice from the Company by the Investor, except as set
forth below.

                                       -4-
<PAGE>
          (b) Investors proposing to distribute all or a portion of their
Registrable Securities through such underwritten offering shall (together with
the Company and any other shareholders distributing their securities through
such underwritten offering) enter into an underwriting agreement in usual and
customary form with the managing underwriter(s) selected for such underwritten
offering by the Company. Notwithstanding any other provision of this Section 3,
if the managing underwriter determines that marketing factors require a
limitation of the number of shares to be underwritten, the managing underwriter
in its sole discretion may limit the number of Registrable Securities to be
included in the registration, or may exclude Registrable Securities entirely
from such registration. In such case, the Company shall so advise all Investors
whose Registrable Securities otherwise would be included in such registration,
and the number of shares of Registrable Securities that may be included in such
registration and underwritten offering shall be allocated among the Investors
requesting registration in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by each of such Investors at
the date of filing of the Registration Statement. If any Investor disapproves of
the terms and conditions of the underwritten offering, such Investor may
withdraw therefrom by written notice to the Company and the managing
underwriter(s). Any Registrable Securities excluded or withdrawn from such
underwritten offering shall be withdrawn from such registration.

          (c) Each Investor hereby agrees that, if requested by the Company and
the managing underwriter(s), it will enter into a customary form of "lock-up"
agreement with the Company and the managing underwriter(s) with respect to any
Registrable Securities then held by such Investor (other than those included in
the registration and underwritten offering described in this Section 3), which
agreement shall contain such terms and conditions no more restrictive on the
Investor's ability to sell or otherwise transfer such Registrable Securities
than those contained in any other such agreements then entered into by the
Company and the managing underwriter(s) with other comparable holders of the
Company's Common Stock.

          (d) Promptly following the expiration or termination of any such
lock-up agreement, the Company will take all reasonable steps, including filing
a Registration Statement in accordance with Section 2(a) hereof (or, in
accordance with Section 4(a) hereof, a post-effective amendment or supplement to
any Registration Statement and prospectus contained therein that previously was
filed in accordance with Section 2(a)), to enable Investors to sell their
remaining Registrable Securities free from restrictions under applicable
securities laws.

          (e) The Company shall have the right to terminate or withdraw any
registration initiated by the Company under this Section 3 prior to the
effectiveness of such registration whether or not any Investor has elected to
include Registrable Securities in such registration.

                                       -5-
<PAGE>
     4. Obligations of the Company. In connection with the registration of the
Registrable Securities pursuant to Sections 2 and 3 hereof, as applicable, the
Company shall:

          (a) prepare promptly, and file with the SEC not later than July 31,
1998, a Registration Statement with respect to the number of Registrable
Securities provided in Section 2(a), and thereafter use its best efforts to
cause each Registration Statement relating to Registrable Securities to become
effective as soon as possible after such filing, and keep the Registration
Statement effective pursuant to Rule 415 at all times until the earliest of (i)
such date as is three years after the date the Registration Statement is first
declared effective by the SEC, (ii) the date, on or after two years after the
Closing Date, on which all of Registrable Securities may be sold without regard
to any requirement under the Securities Act with respect to volume or manner of
sale or the filing of any notice relating thereto, and (iii) the date on which
the Investors no longer beneficially own any Registrable Securities (the period
until such date, the "Registration Period"); submit to the SEC, within five
business days after the Company learns that no review of the Registration
Statement will be made by the staff of the SEC or that the staff of the SEC has
no further comments on the Registration Statement, as the case may be, a request
for acceleration of effectiveness of the Registration Statement to a time and
date not later than 48 hours after the delivery of such request; and the Company
represents and warrants to, and covenants and agrees with, the Investors that
the Registration Statement (including any amendments or supplements thereto and
prospectuses contained therein), at the time it is first filed with the SEC, at
the time it is ordered effective by the SEC and at all times during which it is
required to be effective hereunder (and each such amendment and supplement at
the time it is filed with the SEC and at all time during which it is available
for use in connection with the offer and sale of the Registrable Securities)
shall not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein, or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading;

          (b) prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to the Registration Statement and the
prospectus used in connection therewith as may be necessary to keep such
Registration Statement effective at all times during the Registration Period,
and, during the Registration Period, comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Securities
covered by the Registration Statement until such time as all of such Registrable
Securities have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in the Registration
Statement;

          (c) furnish to each Investor whose Registrable Securities are included
in the Registration Statement and its legal counsel, (i) promptly after the same
is prepared and publicly distributed, filed with the SEC or received by the
Company, one copy of the Registration Statement and any amendment thereto, each
preliminary prospectus and prospectus and each amendment or supplement thereto,
each letter written by or on behalf of

                                       -6-
<PAGE>
the Company to the SEC or the staff of the SEC and each item of written
correspondence from the SEC or the staff of the SEC relating to such
Registration Statement (other than any portion of any thereof that contains
information for which the Company has sought confidential treatment) and (ii)
such number of copies of a prospectus, including a preliminary prospectus, and
all amendments and supplements thereto and such other documents, as such
Investor may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such Investor;

          (d) use reasonable efforts to (i) register and qualify the Registrable
Securities covered by the Registration Statement under such securities or blue
sky laws of such jurisdictions as the Investors who hold a majority in interest
of the Registrable Securities being offered reasonably request, (ii) prepare and
file in those jurisdictions such amendments (including post-effective
amendments) and supplements to such registrations and qualifications as may be
necessary to maintain the effectiveness thereof at all times during the
Registration Period, (iii) take such other actions as may be necessary to
maintain such registrations and qualifications in effect at all times during the
Registration Period and (iv) take all other actions reasonably necessary or
advisable to qualify the Registrable Securities for sale in such jurisdictions;
provided, however, that the Company shall not be required in connection
therewith or as a condition thereto (I) to qualify to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
Section 4(d), (II) to subject itself to general taxation in any such
jurisdiction, (III) to file a general consent to service of process in any such
jurisdiction, (IV) to provide any undertakings that cause more than nominal
expense or burden to the Company or (V) to make any change in its articles or
by-laws, which in each case the Board of Directors of the Company determines to
be contrary to the best interests of the Company and its shareholders;

          (e) in the event that the Registrable Securities are being offered in
an underwritten offering, enter into and perform its obligations under an
underwriting agreement, in usual and customary form, including, without
limitation, customary indemnification and contribution obligations, with the
underwriters of such offering;

          (f) as promptly as practicable after becoming aware of such event or
circumstance, notify each Investor of any event or circumstance of which the
Company has knowledge, as a result of which the prospectus included in the
Registration Statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and use its best efforts promptly to
prepare a supplement or amendment to the Registration Statement to correct such
untrue statement or omission, and deliver a number of copies of such supplement
or amendment to each Investor as such Investor may reasonably request. If such
event is the conduct of negotiations with respect to a transaction, the
disclosure of which the Company reasonably concludes would be detrimental to the
Company (each, a "Negotiation Event"), the Company

                                       -7-
<PAGE>
shall be entitled, upon giving notice of a Negotiation Event to each holder (the
"Negotiation Notice") and upon the reasonable determination of the Company,
after consulting with counsel, that failure to disclose the Negotiation Event
would constitute an omission to state a material fact required to be stated in
the Registration Statement, to require the Investors to suspend sales of the
Common Stock pursuant to the Registration Statement for a period of up to
fifteen (15) days after the giving of the Negotiation Notice; provided, however,
that the Company shall not give more than one (1) Negotiation Notice in any
twelve-month period;

          (g) as promptly as practicable after becoming aware of such event,
notify each Investor who holds Registrable Securities being sold (or, in the
event of an underwritten offering, the managing underwriters) of the issuance by
the SEC of any stop order or other suspension of effectiveness of the
Registration Statement at the earliest possible time;

          (h) permit a single firm of counsel designated as selling
shareholders' counsel by the Investors who hold a majority in interest of the
Registrable Securities being sold to review and comment on the Registration
Statement and all amendments and supplements thereto a reasonable period of time
prior to their filing with the SEC, provided, that to the extent that the
failure of such counsel to respond promptly hereunder results in a delay in the
filing of the registration statement beyond July 31, 1998 or results in the
delay in the effective date thereof beyond the 90-day period specified in
Section 2(c)(ii), the July 31, 1998 filing deadline specified in Section 2(c)(i)
and the 90-day period specified in Section 2(c)(ii) shall be extended by the
amount of such resulting delay;

          (i) make generally available to its security holders as soon as
practical, but not later than 90 days after the close of the period covered
thereby, an earnings statement (in form complying with the provisions of Rule
158 under the Securities Act) covering a twelve-month period beginning not later
than the first day of the Company's fiscal quarter next following the effective
date of the Registration Statement;

          (j) at the request of the Investors who hold a majority in interest of
the Registrable Securities being sold, furnish on the date that Registrable
Securities are delivered to an underwriter, if any, for sale in connection with
the Registration Statement (i) a letter, dated such date, from the Company's
independent certified public accountants in form and substance as is customarily
given by independent certified public accountants to underwriters in
underwritten public offerings, addressed to the underwriters; and (ii) an
opinion, dated such date, from counsel representing the Company for purposes of
such Registration Statement, in form and substance as is customarily given in
underwritten public offerings, addressed to the underwriters and the Investors;

                                       -8-
<PAGE>
          (k) make available for inspection by any Investor, any underwriter
participating in any disposition pursuant to the Registration Statement and a
single firm of counsel and a single firm of accountants or other agents retained
by any such Investor and one firm of attorneys retained by all such underwriters
(collectively, the "Inspectors"), all pertinent financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records"), as shall be reasonably necessary to enable each Inspector to
exercise its due diligence responsibility, and cause the Company's officers,
directors and employees to supply all information that any Inspector reasonably
may request for purposes of such due diligence; provided, however, that each
Inspector shall hold in confidence and shall not make any disclosure (except to
an Investor) of any Record or other information which the Company determines in
good faith to be confidential, and of which determination the Inspectors are so
notified, unless (i) the disclosure of such Records is necessary to avoid or
correct a misstatement or omission in any Registration Statement, (ii) the
release of such Records is ordered pursuant to a subpoena or other order from a
court or government body of competent jurisdiction or (iii) the information in
such Records has been made generally available to the public other than by
disclosure in violation of this or any other agreement. The Company shall not be
required to disclose any confidential information in such Records to any
Inspector until and unless such Inspector shall have entered into
confidentiality agreements (in form and substance satisfactory to the Company)
with the Company with respect thereto, substantially in the form of this Section
4(k). Each Investor agrees that it shall, upon learning that disclosure of such
Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at the Company's own expense, to undertake appropriate action to
prevent disclosure of, or to obtain a protective order for, the Records deemed
confidential. The Company shall hold in confidence and shall not make any
disclosure of information concerning an Investor provided to the Company
pursuant to Sections 5(a) and 5(e) hereof unless (i) disclosure of such
information is necessary to comply with federal or state securities laws, (ii)
the disclosure of such information is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (iii) the release of
such information is ordered pursuant to a subpoena or other order from a court
or governmental body of competent jurisdiction or (iv) such information has been
made generally available to the public other than by disclosure in violation of
this or any other agreement. The Company agrees that it shall, upon learning
that disclosure of such information concerning an Investor is sought in or by a
court or governmental body of competent jurisdiction or through other means,
give prompt notice to such Investor, at such Investor's own expense, to
undertake appropriate action to prevent disclosure of, or to obtain a protective
order for, such information;

          (l) use its best efforts (i) to cause all the Registrable Securities
covered by the Registration Statement to be listed on the Nasdaq National Market
(the "Nasdaq") or such other principal securities market on which securities of
the same class or series issued by the Company are then listed or traded or (ii)
if securities of the same class or series as the

                                       -9-
<PAGE>
Registrable Securities are not then listed on Nasdaq or any such other
securities market, to cause all of the Registrable Securities covered by the
Registration Statement to be listed on the New York Stock Exchange or the
American Stock Exchange;

          (m) provide a transfer agent and registrar, which may be a single
entity, for the Registrable Securities not later than the effective date of the
Registration Statement;

          (n) cooperate with the Investors who hold Registrable Securities being
offered and the managing underwriter(s), if any, to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legends)
representing Registrable Securities to be offered pursuant to the Registration
Statement and enable such certificates to be in such denominations or amounts as
the case may be, as the managing underwriter(s), if any, or the Investors may
reasonably request and registered in such names as the managing underwriter(s),
if any, or the Investors may request; and, within three business days after a
Registration Statement which includes Registrable Securities is ordered
effective by the SEC, the Company shall deliver to the transfer agent for the
Registrable Securities (with copies to the Investors whose Registrable
Securities are included in such Registration Statement) an instruction
substantially in the form attached hereto as Exhibit 1 and shall deliver to the
Investors (with a copy to the Company's transfer agent) an opinion of its
general counsel, in the form attached hereto as Exhibit 2;

          (o) during the Registration Period the Company shall not bid for or
purchase any Common Stock or any right to purchase Common Stock or attempt to
induce any person to purchase any such security or right if such bid, purchase
or attempt would in any way limit the right of the Investors to sell Registrable
Securities by reason of the limitations in Regulation M under the Exchange Act;
and

          (p) take all other reasonable actions necessary to expedite and
facilitate disposition by the Investors of the Registrable Securities pursuant
to the Registration Statement.

     5. Obligations of the Investors. In connection with the registration of the
Registrable Securities, the Investors shall have the following obligations:

          (a) It shall be a condition precedent to the obligations of the
Company to complete the registration pursuant to this Agreement with respect to
the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the registration
of such Registrable Securities and shall execute such documents in connection
with such registration as the Company may reasonably request. At least four days
prior to the first anticipated filing date of the Registration Statement, the
Company shall notify each

                                      -10-
<PAGE>
Investor of the information the Company requires from each such Investor (the
"Requested Information") if any of such Investor's Registrable Securities are
eligible for inclusion in the Registration Statement. If at least one business
day prior to the filing date the Company has not received the Requested
Information from an Investor (a "Non-Responsive Investor"), then the Company may
file the Registration Statement without including Registrable Securities of such
Non-Responsive Investor, but shall not be relieved of its obligation to file a
Registration Statement with the SEC relating to the Registrable Securities of
such Non-Responsive Investor promptly after such Non-Responsive Investor
provides the Requested Information;

          (b) Each Investor by such Investor's acceptance of the Registrable
Securities agrees to cooperate with the Company as reasonably requested thereby
in connection with the preparation and filing of the Registration Statement
hereunder, unless such Investor has notified the Company in writing of such
Investor's election to exclude all of such Investor's Registrable Securities
from the Registration Statement;

          (c) In the event Investors holding a majority in interest of the
Registrable Securities being registered determine to engage the services of an
underwriter, or if an Investor seeks to participate in a registration and
underwritten offering pursuant to Section 3 hereof, each Investor or each such
participating Investor, as the case may be, agrees to enter into and perform
such Investor's obligations under an underwriting agreement, in usual and
customary form, including, without limitation, customary indemnification and
contribution obligations, with the managing underwriter(s) of such offering and
take such other actions as are reasonably required in order to expedite or
facilitate the disposition of the Registrable Securities, unless such Investor
has notified the Company in writing of such Investor's election to exclude all
or a portion of such Investor's Registrable Securities from the Registration
Statement;

          (d) Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 4(f) or
4(g), such Investor will immediately discontinue disposition of Registrable
Securities pursuant to the Registration Statement covering such Registrable
Securities until such Investor's receipt of the copies of the supplemented or
amended prospectus contemplated by Section 4(f) or 4(g) and, if so directed by
the Company, such Investor shall deliver to the Company (at the expense of the
Company) or destroy (and deliver to the Company a certificate of destruction)
all copies in such Investor's possession, of the prospectus covering such
Registrable Securities current at the time of receipt of such notice;

          (e) No Investor may participate in any registration relating to an
underwritten offering hereunder unless such Investor (i) agrees to sell such
Investor's Registrable Securities on the basis provided in any underwriting
arrangements approved by the Investors entitled hereunder to approve such
arrangements, with respect to an

                                      -11-
<PAGE>
underwritten offering under Section 2 hereof, or approved by the Company, with
respect to an underwritten offering under Section 3 hereof; (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such
underwriting arrangements; and (iii) agrees to pay its pro rata share of all
underwriting discounts and selling commissions (and, with respect to an
underwritten offering pursuant to Section 2(b) hereof, any other fees and
expenses) of any investment banker(s) and manager(s) with respect to its
Registrable Securities sold in such offering and of the fees and expenses of
counsel selected by the Investors.

          (f) Each Investor agrees that during the period from the date the
Registration Statement is first declared effective by the SEC to the date of
conversion in full or redemption of all Preferred Shares owned by the Investor,
the Investor shall not engage in short sales or other hedging transactions
relating to the Common Stock, except that the Investor may enter into such
transactions involving a number of shares of Common Stock not to exceed the
number of shares for which a Conversion Notice has been submitted to the
Transfer Agent and the Company (it being understood that this Section 5(f) shall
not restrict such transactions which are otherwise permitted by the Subscription
Agreement or any other agreement between the Investor and the Company).

          (g) Each Investor agrees that it will not effect any disposition of
the Registrable Securities except as contemplated in the Registration Statement
or as is otherwise in compliance with applicable securities laws and that it
will promptly notify the Company of any material change in the information set
forth in the Registration Statement regarding such Investor's plan of
distribution. Each Investor agrees (a) to notify the Company in writing in the
event that such Investor enters into any material agreement with a broker or a
dealer for the sale of the Registrable Securities through a block trade, special
offering or exchange distribution and (b) in connection with such agreement, to
provide to the Company in writing the information necessary to enable the
Company to prepare, at the Company's sole cost and expense, any supplemental
prospectus pursuant to Rule 424(c) under the Securities Act which is required
with respect to such transaction. In connection with any sale of Registrable
Securities which is made pursuant to the Registration Statement, each Investor
shall instruct its broker or brokers to deliver the prospectus to the purchaser
or purchasers in connection with such sale, shall supply copies of such
prospectus to such broker or brokers and shall otherwise use its reasonable best
efforts to comply with the prospectus delivery requirements of the Securities
Act.

     6. Expenses of Registration. All reasonable expenses incurred in effecting
any registration pursuant to this Agreement, including, without limitation, all
registration, listing, qualification, and filing fees, printing and accounting
expenses, fees and disbursements of counsel for the Company, shall be borne by
the Company (except as otherwise may be required under applicable state
securities or blue sky laws); provided, however, that the

                                      -12-
<PAGE>
Investors shall pay all (i) underwriting discounts and selling commissions (and,
with respect to an underwritten offering pursuant to Section 2(b) hereof, any
other fees and expenses) of any investment banker(s) and manager(s) applicable
to the sale of Registrable Securities in an underwritten offering and (ii) fees
and disbursements of counsel to the Investors, in accordance with Sections 2(b)
and 5(e) hereof.

     7. Indemnification. In the event any Registrable Securities are included in
a Registration Statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Investor who holds such Registrable Securities, the
directors, if any, of such Investor, the officers, if any, of such Investor,
each person, if any, who controls any Investor within the meaning of the
Securities Act or the Exchange Act, any underwriter (as defined in the
Securities Act) for the Investors, the directors, if any, of such underwriter
and the officers, if any, of such underwriter, and each person, if any, who
controls any such underwriter within the meaning of the Securities Act or the
Exchange Act (each, an "Indemnified Person"), against any losses, claims,
damages, liabilities or expenses (joint or several) incurred (collectively,
"Claims") to which any of them may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such Claims (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any of the following statements, omissions or violations in the
Registration Statement, or any post-effective amendment thereof, or any
prospectus included therein: (i) any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any
post-effective amendment thereof or the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, (ii) any untrue statement or alleged untrue
statement of a material fact contained in any preliminary prospectus if used
prior to the effective date of such Registration Statement, or contained in the
final prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading or (iii) any violation or alleged violation by the Company
of the Securities Act, the Exchange Act, any state securities law or any rule or
regulation under the Securities Act, the Exchange Act or any state securities
law (the matters in the foregoing clauses (i) through (iii) being, collectively,
"Violations"). Subject to the restrictions set forth in Section 7(d) with
respect to the number of legal counsel, the Company shall reimburse the
Investors and each such underwriter or controlling person, promptly as such
expenses are incurred and are due and payable, for any legal fees or other
reasonable expenses incurred by them in connection with investigating or
defending any such Claim. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 7(a): (I) shall
not apply to a Claim arising out of or based upon a Violation which occurs in
reliance upon and in conformity with information furnished in writing to the

                                      -13-
<PAGE>
Company by any Indemnified Person or underwriter for such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto, if such
prospectus was timely made available by the Company pursuant to Section 4(c)
hereof; (II) with respect to any preliminary prospectus shall not inure to the
benefit of any such person from whom the person asserting any such Claim
purchased the Registrable Securities that are the subject thereof (or to the
benefit of any person controlling such person) if the untrue statement or
omission of material fact contained in the preliminary prospectus was corrected
in the prospectus, as then amended or supplemented, if such prospectus was
timely made available by the Company pursuant to Section 4(c) hereof; and (III)
shall not apply to amounts paid in settlement of any Claim if such settlement is
effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of the Indemnified
Person and shall survive the transfer of the Registrable Securities by the
Investors pursuant to Section 10.

          (b) In connection with any Registration Statement in which an Investor
is participating, each such Investor agrees to indemnify and hold harmless, to
the same extent and in the same manner set forth in Section 7(a), the Company,
each of its directors, each of its officers who signs the Registration
Statement, each person, if any, who controls the Company within the meaning of
the Securities Act or the Exchange Act, any underwriter and any other
shareholder selling securities pursuant to the Registration Statement or any of
its directors or officers or any person who controls such shareholder or
underwriter within the meaning of the Securities Act or the Exchange Act
(collectively and together with an Indemnified Person, an "Indemnified Party"),
against any Claim to which any of them may become subject, under the Securities
Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is
based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with written
information furnished to the Company by such Investor expressly for use in
connection with such Registration Statement; and such Investor will reimburse
any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such Claim; provided, however, that the indemnity
agreement contained in this Section 7(b) shall not apply to amounts paid in
settlement of any Claim if such settlement is effected without the prior written
consent of such Investor, which consent shall not be unreasonably withheld;
provided, further, however, that the Investor shall be liable under this Section
7(b) for only that amount of a Claim as does not exceed the amount by which the
net proceeds to such Investor from the sale of Registrable Securities pursuant
to such Registration Statement exceeds the cost of such Registrable Securities
to such Investor. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investors
pursuant to Section 10. Notwithstanding anything to the contrary contained
herein, the indemnification agreement contained in this Section 7(b) with
respect to any preliminary prospectus shall not inure to the benefit of any
Indemnified Party if the untrue statement or

                                      -14-
<PAGE>
omission of material fact contained in the preliminary prospectus was corrected
on a timely basis in the prospectus, as then amended or supplemented.

          (c) The Company shall be entitled to receive indemnities from
underwriters, selling brokers, dealer managers and similar securities industry
professionals participating in any distribution, to the same extent as provided
above, with respect to information so furnished in writing by such persons
expressly for inclusion in the Registration Statement.

          (d) Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 7 of notice of the commencement of any action
(including any governmental action), such Indemnified Person or Indemnified
Party shall, if a Claim in respect thereof is to be made against any
indemnifying party under this Section 7, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
control of the defense thereof with counsel selected by the indemnifying party
but reasonably acceptable to the Indemnified Person or the Indemnified Party, as
the case may be; provided, however, that an Indemnified Person or Indemnified
Party shall have the right to retain its own counsel with the fees and expenses
to be paid by the indemnifying party, if, in the reasonable opinion of counsel
retained by the indemnifying party, the representation by such counsel of the
Indemnified Person or Indemnified Party and the indemnifying party would be
inappropriate due to actual or potential differing interests between such
Indemnified Person or Indemnified Party and any other party represented by such
counsel in such proceeding. In such event, the Company shall pay for only one
separate legal counsel for the Investors; such legal counsel shall be selected
by the Investors holding a majority in interest of the Registrable Securities
included in the Registration Statement to which the Claim relates. The failure
to deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action shall not relieve such indemnifying party of
any liability to the Indemnified Person or Indemnified Party under this Section
7, except to the extent that the indemnifying party is prejudiced in its ability
to defend such action. The indemnification required by this Section 7 shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as such expense, loss, damage or liability is incurred
and is due and payable.

     8. Contribution. To the extent any indemnification by an indemnifying party
is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise be
liable under Section 7 to the fullest extent permitted by law; provided,
however, that (a) no contribution shall be made under circumstances where the
maker would not have been liable for indemnification under the fault standards
set forth in Section 7, (b) no seller of Registrable Securities guilty of
fraudulent misrepresentation (within the meaning of Section 12(f) of the

                                      -15-
<PAGE>
Securities Act) shall be entitled to contribution from any seller of Registrable
Securities who was not guilty of such fraudulent misrepresentation and (c)
contribution by a seller of Registrable Securities shall be limited in amount to
the amount by which the net amount of proceeds received by such seller from the
sale of such Registrable Securities exceeds the purchase price paid by such
seller for such Registrable Securities.

     9. Reports under Exchange Act. With a view to making available to the
Investors the benefits of Rule 144 promulgated under the Securities Act or any
other similar rule or regulation of the SEC that may at any time permit the
Investors to sell securities of the Company to the public without registration
("Rule 144"), the Company agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

          (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

          (c) furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Exchange Act, (ii) a copy of the most recent annual or quarterly report
of the Company and such other reports and documents so filed by the Company and
(iii) such other information as may be reasonably requested to permit the
Investors to sell such securities pursuant to Rule 144 without registration.

     10. Assignment of the Registration Rights. The rights to have the Company
register Registrable Securities pursuant to this Agreement shall be
automatically assigned by the Investors to any transferee who holds at least 20%
of the Registrable Securities (or Preferred Shares and Warrants convertible or
exercisable into 20% of the Registrable Securities) (or any equivalent
combination of Preferred Shares, Warrants, and Registrable Securities) only if:
(a) the Investor agrees in writing with the transferee or assignee to assign
such rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment; (b) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (i) the
name and address of such transferee or assignee and (ii) the securities with
respect to which such registration rights are being transferred or assigned; (c)
immediately following such transfer or assignment the further disposition of
such securities by the transferee or assignee is restricted under the Securities
Act and applicable state securities laws; (d) at or before the time the Company
received the written notice contemplated by clause (b) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein; (e) such transfer shall have been made in
accordance with the applicable requirements of the Subscription Agreement; (f)
such transferee shall be an "Accredited Investor" as that term

                                      -16-
<PAGE>
defined in Rule 501 of Regulation D promulgated under the Securities Act but
shall not be a broker-dealer or a member of the National Association of
Securities Dealers, Inc.; and (g) in the event the assignment occurs subsequent
to the date of effectiveness of the Registration Statement required to be filed
pursuant to Section 2(a), such assignee or transferee agrees to pay all
reasonable expenses of amending or supplementing such Registration Statement to
reflect such assignment. In connection with any such transfer the Company shall
promptly after such assignment take such actions as shall be reasonably
acceptable to the Initial Investor and such transferee to assure that the
Registration Statement and related prospectus are available for use by such
transferee for sales of the Registrable Securities in respect of which the
rights to registration have been so assigned.

     11. Amendment of Registration Rights. Any provision of this Agreement may
be amended and the observance thereof may be waived (either generally or in a
particular instance and either retroactively or prospectively), only with the
written consent of the Company and Investors who hold or have the right to
acquire a majority in interest of the Registrable Securities. Any amendment or
waiver effected in accordance with this Section 11 shall be binding upon each
Investor and the Company.

     12. Miscellaneous.

          (a) A person or entity is deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

          (b) Notices required or permitted to be given hereunder shall be in

<PAGE>
          (c) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

          (d) This Agreement shall be enforced, governed by and construed in
accordance with the laws of the State of Washington applicable to agreements
made and to be performed entirely within such State. In the event that any
provision of this Agreement is invalid or unenforceable under any applicable
statute or rule of law, then such provision shall be deemed inoperative to the
extent that it may conflict therewith and shall be deemed modified to conform
with such statute or rule of law. Any provision hereof which may prove invalid
or unenforceable under any law shall not affect the validity or enforceability
of any other provision hereof.

          (e) This Agreement constitutes the entire agreement among the parties
hereto with respect to the subject matter hereof. There are no restrictions,
promises, warranties or undertakings, other than those set forth or referred to
herein. This Agreement supersedes all prior agreements and understandings among
the parties hereto with respect to the subject matter hereof.

feminine or neuter, singular or plural, as the context may require.

          (h) The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof.

          (i) The Company acknowledges that any failure by the Company to
perform its obligations under this Agreement, including, without limitation, the
Company's obligations under Section 4(n), or any delay in such performance could
result in damages to the Investors and the Company agrees that, in addition to
any other liability the Company may have by reason of any such failure or delay,
the Company shall be liable for all direct and consequential damages caused by
any such failure or delay; provided, however, that in no event shall the total
damages recoverable by the Investors for claims arising from or related to this
Agreement exceed 150% of the aggregate purchase price paid by the Initial
Investor to the Company for the Preferred Shares, less all amounts received by
the Investors from market resales of shares of Common Stock as contemplated by
this Agreement.

          (j) This Agreement may be executed in two or more counterparts, each
of which shall be deemed an original but all of which shall constitute one and
the same agreement. This Agreement, once executed by a party, may be delivered
to the other party hereto by facsimile of a copy of this Agreement bearing the
signature of the party so delivering this Agreement.

To the Investors listed on Schedule A


ChaseMellon Shareholder Services, L.L.C.
   as Transfer Agent and Registrar
520 Pike Street, Suite 1220
Seattle, WA  98101


Ladies and Gentlemen:

     I am the general counsel of Tera Computer Company, a Washington corporation
(the "Company"), and I understand that [Name of Investor] (the "Holder") has
purchased from the Company an aggregate of ____________ shares (the "Preferred
Shares") of the Company's Series B Convertible Preferred Stock, $.01 par value
(the "Preferred Stock"), and acquired _________ Warrants (the "Warrants"). The
Preferred Shares were purchased and Warrants were acquired by the Holder
pursuant to a Subscription Agreement, dated as of June __, 1998, between the
Holder and the Company (the "Subscription Agreement"). Pursuant to a
Registration Rights Agreement, dated as of June __, 1998, between the Company
and the Holder (the "Registration Rights Agreement") entered into in connection
with the purchase by the Holder of the Preferred Shares, the Company agreed with
the Holder, among other things, to register for resale the shares of Common
Stock issuable upon conversion of the Preferred Shares and exercise of the
Warrants (the "Underlying Shares") under the Securities Act of 1933, as amended
(the "Securities Act"), upon the terms provided in the Registration Rights
Agreement. Pursuant to the Registration Rights Agreement, on __________, the
Company filed a Registration Statement on Form S-3 (File No. 333-__________)
(the "Registration Statement") with the Securities and Exchange Commission (the
"SEC") relating to the Underlying Shares, which names the Holder as a selling
shareholder thereunder.
<PAGE>
     I advise you that, on ________, 1998, a registration statement under the
Securities Act became effective with respect to the resale of the shares of
Common Stock underlying the shares of Preferred Stock and Warrants held by the
Holder. Therefore, I am of the opinion that the Underlying Shares may be resold
by the selling shareholders named in the Prospectus included in such
registration statement and the certificates evidencing the Underlying Shares
need not bear any Securities Act restrictive legend.


                                       Very truly yours,

                                   Schedule A

                                List of Investors


THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"), OR ANY STATE SECURITIES LAWS. THE SALE TO THE HOLDER OF
THIS SECURITY OF THE SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THIS
SECURITY ARE NOT COVERED BY A REGISTRATION STATEMENT UNDER THE ACT OR
REGISTRATION UNDER STATE SECURITIES LAWS. THIS SECURITY HAS BEEN ACQUIRED, AND
SUCH SHARES OF COMMON STOCK MUST BE ACQUIRED, FOR INVESTMENT ONLY AND MAY NOT BE
SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF REGISTRATION OF THE RESALE
THEREOF OR AN OPINION OF COUNSEL REASONABLY ACCEPTABLE IN FORM, SCOPE AND
SUBSTANCE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

                                              Right to Purchase 50,000 Shares of
                                           Common Stock of Tera Computer Company


                              TERA COMPUTER COMPANY

                          Common Stock Purchase Warrant


          TERA COMPUTER COMPANY, a Washington corporation (the "Company"),
hereby certifies that, for value received, __________________________________ or
registered assigns (the "Holder"), is entitled, subject to the terms set forth
below, to purchase from the Company at any time or from time to time after the
date hereof, and before 5:00 p.m., New York City time, on the Expiration Date
(as defined herein), 50,000 fully paid and nonassessable shares of Common Stock,
$.01 par value, of the Company at a purchase price per share equal to the
Purchase Price (as hereinafter defined). The number of such shares of Common
Stock and the Purchase Price are subject to adjustment as provided in this
Warrant.

          As used herein the following terms, unless the context otherwise
requires, have the following respective meanings:

          (a) The term "Business Day" as used herein shall mean a day on which
     the New York Stock Exchange is open for business.

          (b) The term "Common Stock" includes the Company's Common Stock, $.01
     par value per share, as authorized on the date hereof, and any other
     securities into which or for which the Common Stock may be converted or
     exchanged pursuant to a plan of recapitalization, reorganization, merger,
     sale of assets or otherwise.

          (c) The term "Company" shall include Tera Computer Company and any
     corporation that shall succeed to or assume the obligations of Tera
     Computer Company hereunder.

          (d) The term "Expiration Date" refers to June 30, 2003.
<PAGE>
          (e) The term "Other Securities" refers to any capital stock (other
     than Common Stock) and other securities of the Company or any other person
     (corporate or otherwise) which the Holder of this Warrant at any time shall
     be entitled to receive, or shall have received, on the exercise of this
     Warrant, in lieu of or in addition to Common Stock, or which at any time
     shall be issuable or shall have been issued in exchange for or in
     replacement of Common Stock or Other Securities pursuant to Section 4.

          (f) The term "Purchase Price" shall mean $15.00, subject to adjustment
     as provided in this Warrant.

     1. Exercise of Warrant.

          1.1 Exercise at Option of Holder. (a) This Warrant may be exercised by
the Holder hereof in full or in part at any time or from time to time during the
exercise period specified in the first paragraph hereof until the Expiration
Date by surrender of this Warrant and the subscription form annexed hereto (duly
executed) by such Holder to the Company's transfer agent and registrar for the
Common Stock and by making payment, in cash or by certified or official bank
check payable to the Company, or by wire transfer to an account designated by
the Company, in the amount obtained by multiplying (1) the number of shares of
Common Stock designated by the Holder in the subscription form by (2) the
Purchase Price then in effect. On any partial exercise the Company will
forthwith issue and deliver to or upon the order of the Holder hereof a new
Warrant or Warrants of like tenor, in the name of the Holder hereof or as such
Holder (upon payment by such Holder of any applicable transfer taxes) may
request, providing in the aggregate on the face or faces thereof for the
purchase of the number of shares of Common Stock for which such Warrant or
Warrants may still be exercised.

          (b) Notwithstanding any other provision of this Warrant, in no event
shall the holder of this Warrant be entitled at any time to purchase a number of
shares of Common Stock on exercise of this Warrant in excess of that number of
shares upon purchase of which the sum of (1) the number of shares of Common
Stock beneficially owned by such holder and any person whose beneficial
ownership of shares of Common Stock would be aggregated with such holder's
beneficial ownership of shares of Common Stock for purposes of Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
Regulation 13D-G thereunder (each an "Aggregated Person" and collectively, the
"Aggregated Persons") (other than shares of Common Stock deemed beneficially
owned through the ownership of the unexercised portion of this Warrant and any
other security of the Company containing a restriction similar to this Section
1.1(b), including unconverted shares of Series A Convertible Preferred Stock,
$.01 par value, of the Company, and Series B Convertible Preferred Stock, $.01
par value, of the Company, (the "Series B Convertible Preferred Stock")
beneficially owned by all such Aggregated Persons) and (2) the number of shares
of Common Stock issuable upon exercise of the portion of this Warrant with
respect to which the determination in this sentence is being made, would result
in beneficial ownership by any Aggregated Person of more than 4.9% of the
outstanding shares of Common Stock. For purposes of the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Exchange Act and Regulation 13D-G thereunder, except as otherwise
provided in clause (1) of the immediately preceding sentence.

                                       2
<PAGE>
          1.2 Net Issuance. Notwithstanding anything to the contrary contained
in Section 1.1, the Holder may elect to exercise this Warrant in whole or in
part by receiving shares of Common Stock equal to the net issuance value (as
determined below) of this Warrant, or any part hereof, upon surrender of this
Warrant at the principal office of the Company together with notice of such
election, in which event the Company shall issue to the Holder a number of
shares of Common Stock computed using the following formula:

                  X = Y (A-B)
                      -------
                          A

     Where:      X =   the number of shares of Common Stock to be issued to the
                       Holder

                 Y =   the number of shares of Common Stock as to which this
                       Warrant is to be exercised

                 A =   the current fair market value of one share of Common
                       Stock calculated as of the last trading day immediately
                       preceding the exercise of this Warrant

                 B =   the Purchase Price

     As used herein, current fair market value of Common Stock as of a specified
date shall mean with respect to each share of Common Stock the average of the
closing bid prices of the Common Stock on the principal securities market on
which the Common Stock may at the time be traded over a period of five Business
Days consisting of the day as of which the current fair market value of a share
of Common Stock is being determined (or if such day is not a Business Day, the
Business Day next preceding such day) and the four consecutive Business Days
prior to such day. If on the date for which current fair market value is to be
determined the Common Stock is not eligible for trading on any securities
market, the current fair market value of Common Stock shall be the highest price
per share which the Company could then obtain from a willing buyer (other than a
current employee or director) for shares of Common Stock sold by the Company,
from authorized but unissued shares, as determined in good faith by the Board of
Directors of the Company, unless prior to such date the Company has become
subject to a merger, acquisition or other consolidation pursuant to which the
Company is not the surviving party, in which case the current fair market value
of the Common Stock shall be deemed to be the value received by the holders of
the Company's Common Stock for each share thereof pursuant to the Company's
acquisition.

     2. Delivery of Stock Certificates, etc., on Exercise. As soon as
practicable after the exercise of this Warrant, and in any event within three
Business Days thereafter, the Company at its expense (including the payment by
it of any applicable issue or stamp taxes) will cause to be issued in the name
of and delivered to the Holder hereof, or as such Holder (upon payment by such
Holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of fully paid and nonassessable shares of Common
Stock (or Other Securities) to which such Holder shall be entitled on such
exercise, in such denominations as may be requested by such Holder, plus, in
lieu of any fractional share to which such Holder would otherwise be entitled,
cash equal to such fraction multiplied by the then current fair market value (as
determined in accordance with

                                       3
<PAGE>
subsection 1.2) of one full share, together with any other stock or other
securities or property (including cash, where applicable) to which such Holder
is entitled upon such exercise pursuant to Section 1 or otherwise. Upon exercise
of this Warrant as provided herein, the Company's obligation to issue and
deliver the certificates for Common Stock shall be absolute and unconditional,
irrespective of any action or inaction by the Holder to enforce the same, any
waiver or consent with respect to any provision thereof, the recovery of any
judgment against any person or any action to enforce the same, any failure or
delay in the enforcement of any other obligation of the Company to the Holder,
or any setoff, counterclaim, recoupment, limitation or termination, or any
breach or alleged breach by the Holder or any other person of any obligation to
the Company or any violation or alleged violation of law by the Holder or any
other person, and irrespective of any other circumstance which might otherwise
limit such obligation of the Company to the Holder in connection with such
exercise. If the Company fails to issue and deliver the certificates for the
Common Stock to the Holder pursuant to the first sentence of this paragraph as
and when required to do so, in addition to any other liabilities the Company may
have hereunder and under applicable law, the Company shall pay or reimburse the
Holder on demand for all out-of-pocket expenses including, without limitation,
fees and expenses of legal counsel incurred by the Holder as a result of such
failure.

     3. Adjustment for Dividends in Other Stock, Property, etc.;
Reclassification, etc. In case at any time or from time to time, all the holders
of Common Stock (or Other Securities) shall have received, or (on or after the
record date fixed for the determination of shareholders eligible to receive)
shall have become entitled to receive, without payment therefor,

          (a) other or additional stock or other securities or property (other
     than cash) by way of dividend, or

          (b) any cash (excluding cash dividends payable solely out of earnings
     or earned surplus of the Company), or

          (c) other or additional stock or other securities or property
     (including cash) by way of spin-off, split-up, reclassification,
     recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other Securities) issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in Section 5), then and in each such case the Holder of this Warrant, on the
exercise hereof as provided in Section 1, shall be entitled to receive the
amount of stock and other securities and property (including cash in the cases
referred to in subdivisions (b) and (c) of this Section 3) which such Holder
would hold on the date of such exercise if on the date hereof the Holder had
been the holder of record of the number of shares of Common Stock called for on
the face of this Warrant and had thereafter, during the period from the date
hereof to and including the date of such exercise, retained such shares and all
such other or additional stock and other securities and property (including cash
in the case referred to in subdivisions (b) and (c) of this Section 3)
receivable by the Holder as aforesaid during such period, giving effect to all
adjustments called for during such period by Section 4.

                                       4
<PAGE>
     4. Exercise upon Reorganization, Consolidation, Merger, etc. In case at any
time or from time to time, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person, (c) effect an exchange of
outstanding shares of the Company for securities of any other person or (d)
transfer all or substantially all of its properties or assets to any other
person under any plan or arrangement contemplating the dissolution of the
Company, then, in each such case, as a condition of such reorganization,
consolidation, merger, share exchange, sale or conveyance, the Company shall
cause effective provisions to be made so that the Holder shall have the right
thereafter, by exercising this Warrant (in lieu of the shares of Common Stock of
the Company purchasable and receivable upon exercise of the rights represented
hereby immediately prior to such transaction) to purchase the kind and amount of
shares of stock and other securities and property (including cash) receivable
upon such reorganization, consolidation, merger, share exchange, sale or
conveyance by a holder of the number of shares of Common Stock that might have
been received upon exercise of this Warrant immediately prior to such
reorganization, consolidation, merger, share exchange, sale or conveyance;
provided, however, that in the event (x) the value of the stock, securities or
other assets or property (determined in good faith by the Board of Directors of
the Company) issuable or payable with respect to one share of Common Stock of
the Company purchasable and receivable upon the exercise of the rights
represented hereby immediately prior to such transaction is in excess of the
Purchase Price hereof in effect at the time of such reorganization,
consolidation, merger, share exchange, sale or conveyance (after giving effect
to any adjustment in such Purchase Price required to be made under the terms of
this Warrant), and (y) the securities, if any, to be received in such
reorganization, consolidation, merger, share exchange, sale or conveyance are
publicly traded, then if the Company gives the Holder at least 20 Business Days
(or such lesser period as the Company gives notice of such transaction to the
holders of the outstanding shares of Common Stock) prior notice of such
reorganization, merger, share exchange, sale or conveyance this Warrant shall
expire unless exercised prior to such reorganization, consolidation, merger,
share exchange, sale or conveyance. Any such provision shall include provisions
for adjustments in respect of such shares of stock and other securities and
property that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Warrant. The provisions of this Section shall
apply to successive reorganizations, consolidations, mergers, share exchanges,
sales and conveyances.

     5. Adjustment for Extraordinary Events. In the event that the Company shall
(a) issue additional shares of the Common Stock as a dividend or other
distribution on outstanding Common Stock, (b) subdivide or reclassify its
outstanding shares of Common Stock, or (c) combine its outstanding shares of
Common Stock into a smaller number of shares of Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 5.
The Holder of this Warrant shall thereafter, on the exercise hereof as provided
in Section 1, be entitled to receive that number of shares of Common Stock
determined by multiplying the number of shares of Common Stock which would be
issuable on such exercise as of immediately prior to such

                                       5
<PAGE>
issuance by a fraction of which (x) the numerator is the Purchase Price in
effect immediately prior to such issuance and (y) the denominator is the
Purchase Price in effect on the date of such exercise.

     6. Further Assurances. The Company will take all action that may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable shares of stock, free from all taxes, liens and
charges with respect to the issue thereof, on the exercise of all or any portion
of this Warrant from time to time outstanding.

     7. Notices of Record Date, etc. In the event of

          (a) any taking by the Company of a record of the holders of any class
     of securities for the purpose of determining the holders thereof who are
     entitled to receive any dividend on, or any right to subscribe for,
     purchase or otherwise acquire any shares of stock of any class or any other
     securities or property, or to receive any other right, or

          (b) any capital reorganization of the Company, any reclassification or
     recapitalization of the capital stock of the Company or any transfer of all
     or substantially all of the assets of the Company to or consolidation or
     merger of the Company with or into any other person, or

then and in each such event the Company will mail or cause to be mailed to the
Holder, at least ten days prior to such record date, a notice specifying (i) the
date on which any such record is to be taken for the purpose of such dividend,
distribution or right, and stating the amount and character of such dividend,

reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up is to take place, and the time, if any is
to be fixed, as of which the holders of record of Common Stock (or Other
Securities) shall be entitled to exchange their shares of Common Stock (or Other
Securities) for securities or other property deliverable on such reorganization,
reclassification, recapitalization, transfer, consolidation, merger,
dissolution, liquidation or winding-up; and (iii) the amount and character of
any stock or other securities, or rights or options with respect thereto,

the Securities Act of 1933, as amended (the "Securities Act"), or a favorable
vote of shareholders, if either is required. Such notice shall be mailed at
least ten days prior to the date specified in such notice on which any such
action is to be taken or the record date, whichever is earlier.

attorney, upon surrender of this Warrant properly endorsed.

     10. Register of Warrants. The Company shall maintain, at the principal

Holder hereof), a register in which the Company shall record the name and
address of the person in whose name this Warrant has been issued, as well as the

hereof by the Holder hereof at the office or agency of the Company referred to
in Section 10, for one or more new Warrants of like tenor representing in the
aggregate the right to subscribe for and purchase the number of shares of Common

and cancellation of this Warrant, the Company at its expense will execute and

     13. Warrant Agent. In accordance with the instruction letter, dated June
26, 1998, from the Company to ChaseMellon Shareholder Services, L.L.C. (the
"Transfer Agent"), the Transfer Agent will act as the exercise agent for the
purpose of issuing Common Stock (or Other Securities) on the exercise of this
Warrant pursuant to Section 1. The Company may, by written notice to the Holder,
appoint an agent having an office in the United States of America, for the
purpose of issuing Common Stock (or Other Securities) on the exercise of this
Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section 11,
and replacing this Warrant pursuant to Section 12, or any of the foregoing, and
thereafter any such issuance, exchange or replacement, as the case may be, shall
be made at such office by such agent.

     14. Remedies. The Company stipulates that the remedies at law of the Holder
of this Warrant in the event of any default or threatened default by the Company
in the performance of or compliance with any of the terms of this Warrant are
not and will not be adequate, and that such terms may be specifically enforced
by a decree for the specific performance of any agreement contained herein or by
an injunction against a violation of any of the terms hereof or otherwise.

     15. No Rights or Liabilities as a Shareholder. This Warrant shall not
entitle the Holder hereof to any voting rights or other rights as a shareholder

<PAGE>
Stock, and no mere enumeration herein of the rights or privileges of the Holder
hereof, shall give rise to any liability of such Holder for the Purchase Price
or as a shareholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

     16. Notices, etc. All notices and other communications from the Company to
the registered Holder of this Warrant shall be mailed by first class certified
mail, postage prepaid, at such address as may have been furnished to the Company
in writing by such Holder or at the address shown for such Holder on the
register of Warrants referred to in Section 10.

     17. Investment Representations. By acceptance of this Warrant, the Holder
represents to the Company that this Warrant is being acquired for the Holder's
own account and for the purpose of investment and not with a view to, or for
sale in connection with, the distribution thereof, nor with any present
intention of distributing or selling the Warrant or the Common Stock issuable
upon exercise of the Warrant. The Holder acknowledges that the Holder has been
afforded the opportunity to meet with the management of the Company and to ask
questions of, and receive answers from, such management and the Company's
counsel about the business and affairs of the Company and concerning the terms
and conditions of the offering of this Warrant, and to obtain any additional
information, to the extent that the Company possessed such information or could
acquire it without unreasonable effort or expense, necessary to verify the
accuracy of the information otherwise obtained by or furnished to the Holder in
connection with the offering of this Warrant. The Holder asserts that it may be
considered to be a sophisticated investor, is familiar with the risks inherent
in speculative investments such as in the Company, has such knowledge and
experience in financial and business matters that it is capable of evaluating
the merits and risks of the investment in this Warrant and the Common Stock
issuable upon exercise of this Warrant, and is able to bear the economic risk of
the investment. The Holder acknowledges and agrees that this Warrant and, except
as otherwise provided in the Registration Rights Agreement between the original
Holder of the Series B Convertible Preferred Stock and the Company, as amended
or modified from time to time (the "Registration Rights Agreement"), the shares
of Common Stock issuable upon exercise of this Warrant (if any) have not been
(and at the time of acquisition by the Holder, will not have been or will not
be) registered under the Securities Act or under the securities laws of any
state, in reliance upon certain exemptive provisions of such statutes. The
Holder recognizes and acknowledges that such claims of exemption are based, in
part, upon the representations of the Holder contained herein. The Holder
further recognizes and acknowledges that because this Warrant and, except as
provided in the Registration Rights Agreement, the Common Stock issuable upon
exercise of this Warrant (if any) are unregistered, they may not be eligible for
resale, and may only be resold in the future pursuant to an effective
registration statement under the Securities Act and any applicable state
securities laws, or pursuant to a valid exemption from such registration
requirements. Unless the shares of Common Stock have theretofore been registered
for resale or are otherwise exempt from registration under the Securities Act,
the Company may require, as a condition to the issuance of Common Stock upon the
exercise of this Warrant (i) in the case of an exercise in accordance with
Section 1.1 hereof, a confirmation as of the date of exercise of the Holder's
representations pursuant to this Section 17 or (ii) in the case of an exercise
in accordance with Section 1.2 hereof, an opinion of counsel (in form, scope and
substance reasonably satisfactory to the Company) that the shares of Common
Stock to be issued upon such exercise may be issued without registration under
the Securities Act.

                                       8
<PAGE>
     18. Legend. Unless theretofore registered for resale under the Securities
Act or otherwise exempt from registration under the Securities Act when issued
upon exercise of this Warrant and when resold thereafter, each certificate for
shares issued upon exercise of this Warrant shall bear the following legend:

          The securities represented by this certificate have not been
          registered under the Securities Act of 1933, as amended. The
          securities have been acquired for investment and may not be
          sold, transferred or assigned in the absence of an effective
          registration statement for the securities under the
          Securities Act of 1933, as amended, or an opinion of counsel
          reasonably satisfactory in form, scope and substance to the
          Company that registration is not required under said Act.

     19. Miscellaneous. This Warrant and any terms hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement or such change, waiver, discharge or termination
is sought. This Warrant shall be construed and enforced in accordance with and
governed by the internal laws of the State of Washington. The headings in this
Warrant are for purposes of reference only, and shall not limit or otherwise
affect any of the terms hereof. The invalidity or unenforceability of any
provision hereof shall in no way affect the validity or enforceability of any
other provision.

     IN WITNESS WHEREOF, Tera Computer Company has caused this Warrant to be
executed on its behalf by one of its officers thereunto duly authorized.

Board of Directors of
Tera Computer Company

Dear Sirs:

     I have supervised the corporate proceedings relative to the issuance of
6,000 shares of Series B Convertible Preferred Stock, $.01 par value (the
"Series B Preferred Stock"), and 100,000 common stock purchase warrants (the
"Warrants"), of Tera Computer Company, a Washington corporation (the "Company"),
and of the authorization of shares of common stock, $.01 par value (the "Common
Stock"), issuable upon conversion of the Series B Preferred Stock and exercise
of the Warrants.

     I also am familiar with the corporate proceedings relative to the
incorporation of the Company and to its present corporate status. Based upon the
foregoing and having regard for such legal considerations as I have deemed
relevant, I am of the opinion that:

     1. The Company is a corporation duly incorporated and validly existing
under the laws of the State of Washington, with full corporate power to issue
the Series B Preferred Stock and the Warrants and to issue the Common Stock
reserved for issuance upon conversion of the Series B Preferred Stock and
exercise of the Warrants.

     2. The shares of the Series B Preferred Stock have been duly authorized by
appropriate corporate action and are validly issued, fully paid, and
nonassessable.

     3. The shares of Common Stock issuable upon conversion of the Series B
Preferred Stock and exercise of the Warrants have been duly authorized and
reserved for such purpose by appropriate corporate action and, when issued upon
such conversion or exercise, as the case may be, will be validly issued, fully
paid, and nonassessable.

     This opinion may be used in connection with qualification of such shares of
Common Stock under the applicable securities laws of any state.

                                       Very truly yours,

                                       /s/ KENNETH W. JOHNSON

                                       Kenneth W. Johnson, Esq.
                                       Vice President - Finance
                                       and General Counsel

                          INDEPENDENT AUDITORS' CONSENT
