BASIS OF PRESENTATION

        The accompanying balance sheets and related interim statements of
operations and cash flows have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of
management, all adjustments considered necessary for fair presentation have been
included. Interim results are not necessarily indicative of results for a full
year. The information included in this Form 10-Q should be read in conjunction
with Management's Discussion and Analysis and the financial statements and notes
thereto included in the Company's restated financial statements for the years
ended December 31, 1996 and 1997, and the period from December 7, 1987 through
December 31, 1997, contained in the Company's Annual Report on Form 10-K/A for
the fiscal year ended December 31, 1997.

NET LOSS PER COMMON SHARE

        Net loss per common share is computed on the basis of the weighted 
average number of shares of Common Stock outstanding. As outstanding stock 
options, warrants and preferred stock are antidilutive, their effect has not 
been included in the calculation of net loss per share.

INVENTORY

        Inventory consisted of the following:

CHANGES IN CAPITAL

        The Company previously classified its Series A Convertible Preferred
Stock, issued in December 1997, and its Series B Convertible Preferred Stock,
issued in June 1998, as redeemable securities as the governing instruments for
both securities contained conditions for redemption which were not solely within
the control of 



                                       6
<PAGE>   7

the Company; for example a significant decline in the market value of the
Company's common stock which could lead to a delisting of the common stock from
the Nasdaq National Market System. The Company and each of the holders of these
securities have entered into agreements providing that the holders no longer may
redeem these securities if the condition otherwise giving rise to a redemption
right by the holders is not solely within the control of the Company. Therefore,
these securities are now classified as Shareholders' Equity.

        The Company previously reported the issuance on June 30, 1998, of 6,000
shares of Series B Convertible Preferred Stock and 100,000 warrants, with an
exercise price of $15.00 per share. The warrants were valued at $464,733 (net of
allocated offering costs), using the Black-Scholes method. The discount arising
from the allocation of proceeds to the warrants has been amortized as a return
of capital to the preferred shareholders over the period the related Series B
Convertible Preferred was first convertible, which occurred in the three months
ended September 30, 1998.

        On September 30, 1998, the Company issued 600,000 shares of Common Stock
and five year warrants to purchase 121,008 shares of Common Stock with an
exercise price of $10.04 per share, subject to adjustment, for total proceeds of
$6,000,000, less offering expenses. Of the proceeds, $3,000,000 were received on
September 30, 1998; the remaining $3,000,000 were in transit on September 30,
1998, and were received on October 1, 1998. See Item 2 under Part II, below, for
additional information regarding this financing.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

PRELIMINARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        The information set forth in this Item 2 includes forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act, as amended, and is
subject to the safe harbor created by those sections. For a discussion of Risk
Factors that could affect the Company's future performance, please see "Business
- - - - Risk Factors" contained in the Company's Annual Report on Form 10-K/A for the
fiscal year ended December 31, 1997.

OVERVIEW

        The Company had an accumulated net loss from operations of approximately
$58.8 million as of September 30, 1998. The Company's funding to date has been
primarily from the sale of approximately $70.8 million in securities, research
funding from the Defense Advanced Research Projects Agency ("DARPA"), of
approximately $19.2 million, and product sales of approximately $1.3 million.



                                       7
<PAGE>   8

        The Company has experienced net losses in each year of operations and
expects to incur further substantial losses until additional sales are made, and
possibly thereafter. In April 1998 the Company recognized its first revenue from
system sales with its delivery of a two-processor MTA system to the San Diego
Supercomputer Center ("SDSC"); through September 30, 1998, the Company had not
generated any earnings. The Company plans to upgrade the SDSC system in stages
to larger configurations as it receives production printed circuit boards,
integrated circuits and other components that are integrated into a commercially
acceptable system. See "Business - Risk Factors - Development Status of the MTA
System" and " - Manufacturing Risks; Reliance On And Capacity Of Third-Party
Sole Source Suppliers" and "Business - Strategy" in the Company's Annual Report
on Form 10-K/A for the fiscal year ended December 31, 1997.

RESULTS OF OPERATIONS

THREE AND NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1998

        Revenue. The Company recorded revenue in the first nine months of 1998
of approximately $1.8 million, of which $232,000 was recognized in the third
quarter pursuant to a subcontract with SDSC to evaluate multithreaded
architecture for certain defense applications. The Company expects to complete
this subcontract in for an additional $487,000, of which the Company's portion,
after payments to subcontractors, will be approximately $183,000; this
subcontract expires on June 30, 1999. The Company may obtain additional revenues
in 1998 from the sale of larger configurations to SDSC and from other sales to
potential customers, although it currently has no purchase orders for sales to
other customers.

        Operating Expenses. Cost of revenue for the third quarter and the first
nine months of 1998, largely arising from the company's first system sales to
SDSC in the second quarter, were high as a percentage of sales due to favorable
pricing terms provided to SDSC and the inclusion of costs of system
infrastructure to support a full 16-processor MTA system.

        Research and development expenses include costs associated with the
development of the MTA system, including personnel expense, depreciation and
lease expense on facilities and equipment, nonrecurring engineering, software
and hardware costs and preproduction expenses. Research and development expenses
for the three and nine months ended September 30, 1998 were $3.3 million and
$11.2 million, respectively, representing approximately 79% and 82% of the
respective net operating expenses for each period, compared to $3.9 million and
$9.0 million for the same respective periods in 1997, which represented
approximately 88% and 87% of such periods' respective net operating expenses.
During the third quarter, approximately $1.3 million of the $3.3 million were
related to the completion and testing of the initial MTA system, preproduction
costs and expense related to inventory revaluation and obsolescence due to
redesign and optimization of components in inventory, compared to $2.0 million
for such items in the third 



                                       8
<PAGE>   9

quarter of 1997. The corresponding figures for the first nine months of 1998
were $5.0 million compared to $3.7 million for the first nine months of 1997;
this difference primarily arose from inventory obsolescence recognized in the
first quarter of 1998. Although non-recurring hardware engineering expenses for
the current MTA implementation should continue to decrease, research and
development expenses will continue to be a major expense as the Company devotes
greater effort to future system development.

        Marketing and sales expenses for the three and nine months ended
September 30, 1998 were $484,000 and $1.27 million, respectively, compared to
$262,000 and $635,000 for the same periods in 1997, representing an increase of
85% over the third quarter of 1997 and 100% over the first nine months of 1997.
General and administrative expenses for the first three and nine months ended
September 30, 1998 were $516,000 and $1.50 million, respectively, compared to
$367,000 and $1.07 million for the same periods in 1997, representing an
increase of 41% in the third quarter and 40% for the nine month period. The
increase in marketing and sales expenses was due to additional sales and
applications staff, increased marketing efforts and higher wages, while the
increase in general and administrative expenses was due largely to additional
staff, operating costs associated with being a publicly owned company and higher
wages. These expenses are expected to increase commensurate with any growth in
the Company's operations.

        Research Funding. The Company currently is billing DARPA under a
research contract awarded in September 1995. Billings under this contract were
approximately $181,000 in the first nine months of 1998, with $106,000 billed in
the third quarter, and $282,000 left to be billed under this contract.

        Other Income. Other income, net of other expense, increased to $164,000
in the first nine months of 1998, largely due to interest received on the
Company's increased cash balances. Other net income in the third quarter of
1998, however, was about $63,000, as compared to $104,000 for the third quarter
of 1997.

        Taxes. There was no provision for federal income taxes in any period as
the Company has continued to incur net operating losses.

        Preferred Stock. The Company recorded a $141,000 cumulative charge for
dividends on the Company's Series A and Series B Convertible Preferred Stock in
the third quarter, all of which has been paid by the issuance of 19,934 shares
of the Company's Common Stock. In addition, the Company amortized in the third
quarter the preferred stock discount resulting from the allocation of proceeds
to warrants issued on June 30, 1998; this resulted in a $465,000 non-cash charge
to the Loss for Common Stock.

        Year 2000. Although it has not completed a formal inquiry of its
suppliers and customers, the Company does not expect that issues relating to the
Year 2000 problem will be significant to its financial condition or results of
operations. No 



                                       9
<PAGE>   10

significant modifications to its internal computer system are necessary to
address Year 2000 issues, and it does not anticipate that any issues affecting
its suppliers and customers will substantially affect the Company's operations.

LIQUIDITY AND CAPITAL RESOURCES

        Since its inception through September 30, 1998, the Company's principal
sources of liquidity have been net proceeds from the sale of securities totaling
$70.8 million, DARPA research funding of approximately $19.2 million and sales
receipts of approximately $1.3 million. At September 30, 1998, the Company had
$8.3 million in cash, cash equivalents and funds in transit, $384,000 in
accounts receivable and no bank line of credit.

        During the remainder of 1998 and the first half of 1999, the Company's
working capital needs will depend primarily upon its personnel costs and the
cost of inventory, as well as manufacturing startup costs and research and
development expenses related to future implementations of the MTA system. In the
first nine months of 1998, overall wages and benefits increased by about 55%
over the first nine months of 1997 to approximately $7.0 million, reflecting
both additional personnel (which increased from 75 to 102 from the end of
September 1997 to the end of September 1998) and higher wages, while total
expenditures related to inventory increased to approximately $7.6 million in the
first nine months of 1998, a $4.4 million increase over the first nine months of
1997. Personnel costs are expected to increase gradually as additional employees
are added; the level of inventory expenditures will depend upon further orders
for MTA systems and the timing of future sales and deliveries. The Company has
experienced delays in the receipt 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.

        Although the Company believes its current cash resources, together with
funds anticipated from future sales of MTA systems, to be sufficient to continue
anticipated levels of business operations through 1998, the Company believes it
will need to raise additional capital by early 1999. 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. There
can be no assurance that any additional financing will be available on
acceptable terms when needed or that such financings will not be dilutive to the
Company's shareholders.

                           PART II. OTHER INFORMATION

ITEM 2.  CHANGES IN SECURITIES

        On September 30, 1998, the Company raised $6,000,000 dollars through the
negotiated private sale of 600,000 shares of Common Stock and five year warrants
to purchase 121,008 shares of Common Stock, with a per share exercise price of
$10.04, subject to adjustment, to two accredited investors, Advantage Fund II
Ltd., and Koch Industries, Inc. Further information regarding the Common Stock
and the warrants is contained under "Changes in Capital" in the Notes to
Financial Statements, above. There were no sales agents or underwriters involved
in this placement. These sales were exempt from the registration provisions of
the Securities Act of 1933 pursuant to Section 4(2) thereof, based on the nature
of the offering and status of the offerees.

        Pursuant to the Subscription Agreement between the Company and the
investors, the Company would be required to issue additional shares of Common
Stock to the holders if the average closing price of the Common Stock is below
$12.00 for the 15 trading days immediately prior to February 22, 1999 (or such
later date as a registration statement covering the resale of the shares of
Common Stock issued and issuable to the investors becomes effective). There are
similar adjustment periods with respect to these securities still owned by the
investors each three months thereafter through September 30, 2001.

                                WAIVER AGREEMENT

        THIS WAIVER AGREEMENT, dated as of December 23, 1997, is by and between
TERA COMPUTER COMPANY, a Washington corporation (the "Company"), and ADVANTAGE
FUND II LTD., a British Virgin Islands corporation (the "Buyer").

        WHEREAS, the Company and the Buyer entered into a Subscription
Agreement, dated as of December 23, 1997 (the "Subscription Agreement"),
pursuant to which the Company issued to the Buyer certain shares of the
Company's Series A Convertible Preferred Stock, $.01 par value ("Preferred
Stock"), and warrants to purchase shares of the Company's common stock, $.01 par
value ("Common Stock"), and in connection therewith the Company and the Buyer
entered into a Registration Rights Agreement, dated as of December 23, 1997 (the
"Registration Rights Agreement"); and

        WHEREAS, the Company and the Buyer have been informed that certain
provisions of the Statement of Rights and Preferences of the Preferred Stock
(the "Statement") may be construed, under generally accepted accounting
principles and rules and regulations of the Securities and Exchange Commission,
as requiring that the Company classify the shares of Preferred Stock issued to
the Buyer as "redeemable" shares of Preferred Stock on the Company's financial
statements; and

        WHEREAS, neither the Company nor the Buyer intended that the shares of
Preferred Stock issued to the Buyers be so classified; and

        WHEREAS, the parties desire to correctly state their intent and
understanding;

        NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants contained herein, the parties hereby agree as follows:

1. (a) Notwithstanding Sections 4 and 8 and any other provision of the
Statement, if (A) an Optional Redemption Event occurs by reason of the
occurrence of an event described in clause (1), (2) or (5) of Section 8(a) of
the Statement, or (B) the Company is required to redeem shares of Preferred
Stock by reason of the occurrence of an event described in Section 4(a) of the
Statement, and such occurrence is by reason of events which are not solely
within the control of the Company, then the Company, in its sole discretion, may
elect not to redeem any or all of the shares of Preferred Stock and, if the
Company so elects, then the Buyer hereby waives any and all rights to require
the Company to so redeem such shares of Preferred Stock under such provisions.
In order to make such election, the Company shall so notify the



                                       1
<PAGE>   2

Buyer which has given either an Optional Redemption Notice or has given a notice
to the Company directing the Company to redeem shares of Preferred Stock
pursuant to Section 4(a)(2) (an "Inconvertibility Redemption Notice"), as the
case may be, and shall deliver to the Buyer an Auditor's Determination (as
defined below) within ten (10) Business Day's after the Company's receipt of an
Optional Redemption Notice or an Inconvertibility Redemption Notice.

        (b) If the Company so elects and notifies the Buyer, then, for each
thirty (30) days that such Optional Redemption Event or Share Limitation Event
(as defined below), as the case may be, continues to exist, commencing as of the
first Business Day of the event which gave rise to such Optional Redemption
Event or such Share Limitation Event, the Conversion Percentage shall be
permanently reduced by six percentage points and the Ceiling Price shall be
permanently reduced by six percent of the amount the Ceiling Price otherwise
would have been without any reduction pursuant to this clause (such Conversion
Percentage and Ceiling Price reduction shall be pro rated for any period of, or
in case the Optional Redemption Event or Share Limitation Event ceases to exist
in, less than thirty (30) days), provided that the Conversion Percentage and
Ceiling Price shall not be so reduced if the Company duly and timely issues a
Shareholder Approval Notice and obtains Shareholder Approval pursuant to Section
4 of the Statement.

        (c) With respect to a Share Limitation Event, on or after the date the
Company gives a Shareholder Approval Notice, the Company promptly shall call a
special meeting of its shareholders, to be held not later than 60 days after
such Notice is given, to seek the Shareholder Approval for the issuance of all
shares of Common Stock issuable in accordance with the Statement and this
Agreement without regard to Rule 4460(i) of Nasdaq or any similar or successor
provision (the "Rule") and shall use its best efforts to obtain the Shareholder
Approval. The Company shall prepare and file with the SEC within 20 days after
such notice is given preliminary proxy materials which set forth a proposal to
seek such Shareholder Approval. The Company shall provide the Buyer an
opportunity to consult with the Company regarding the content of such proxy
materials insofar as it relates to the Shareholder Approval by providing copies
of such preliminary proxy materials and any revised preliminary proxy materials
to the Buyer a reasonable period of time prior to their filing with the SEC. The
Company shall furnish to the Buyer a copy of its definitive proxy materials for
such special meeting and any amendments or supplements thereto promptly after
the same are mailed to shareholders or filed with the SEC. Upon the earlier of
(i) the failure to obtain the Shareholder Approval at the special meeting or
(ii) the failure to hold the special meeting within such 60-day period, the
Company shall so notify the Buyer and such of the following as shall be
specified by notice to the Company from the Buyer shall occur: (1) the
Conversion Percentage and the Ceiling Price shall be reduced pursuant to

<PAGE>   3

Subsection (b) above and (2) the Company shall promptly file applications and
take all other actions necessary to (i) list the Common Stock for trading and
quotation on the OTC Bulletin Board or such other securities market or exchange
which will not restrict the number of shares of Common Stock issuable under this
Agreement and (ii) upon filing such applications, request the immediate removal
of the Common Stock from listing on the securities market on which it is then
listed which restricts the issuance of shares of Common Stock under this
Agreement without the Shareholder Approval. Upon obtaining such Shareholder
Approval or listing, as the case may be, the Company shall issue promptly all
shares of Common Stock due through the date of such issuance.

For purposes of this Agreement, the term "Share Limitation Event" means a time
at which the Company is unable to redeem all shares of Preferred Stock otherwise
required to be redeemed pursuant to Section 4(a) of the Statement by reason of
events which are not solely within the control of the Company.

        (d) For purposes of this Agreement, (A) an Optional Redemption Event
described in clause (1), (2) or (5) of the definition of the term "Optional
Redemption Event" or (B) a requirement of the Company to redeem shares pursuant
to Section 4(a) of the Statement shall be deemed to have occurred by reason of
events which are not solely within the control of the Company if a requirement
of the Company to redeem, or a right of any holder of shares of Preferred Stock
to require redemption of, shares of Preferred Stock by reason thereof, would
result in the Company being required to classify the Preferred Stock as
redeemable preferred stock on a balance sheet of the Company prepared in
accordance with generally accepted accounting principles and Regulation S-X of
the SEC.

        (e) For purposes of this Agreement, the term "Auditor's Determination"
shall mean a written determination signed by the Auditors concurring with the
Company's conclusion that (A) the Optional Redemption Event described in the
applicable clause (1), (2) or (5) of the definition of Optional Redemption Event
in Section 8(a) of the Statement or (B) a requirement of the Company to redeem
shares pursuant to Section 4(a) of the Statement, was due to the occurrence of
events which were not solely within the control of the Company, as such phrase
is defined in Subsection (d) immediately above. The Auditor's Determination
shall (i) set forth in reasonable detail all relevant facts considered by the
Auditors in connection therewith, (ii) set forth all applicable accounting
principles and assumptions used, and (iii) set forth in reasonable detail or
attach copies of all legal, expert and other advice or information used by the
Auditors in reaching their conclusion. To the extent any facts are assumed for
purposes of the Auditor's Determination, the validity of such conclusion or
determination shall depend upon such assumed facts being true and complete in
all material respects.

recognized independent accounting firm then serving as the Company's auditors or
such other "big five" nationally recognized accounting firm (including
successors thereto) as the Company may designate. The fees and expenses of the
Auditors shall be paid by the Company.

2. This Agreement is binding upon the Buyer, any holder which acquires the
Preferred Stock from the Buyer, and any and all successors and assigns of the
Buyer. The Buyer hereby agrees to deliver this document to all transferees of
the Preferred Stock and to surrender the certificates evidencing the Preferred
Stock to the Company, at the Company's request, so that an appropriate legend
evidencing this Agreement may be added to such certificates.

3. The recitals made above are an integral part of this Agreement and are hereby
incorporated herein and made a part hereof as though set forth in full in this
Section.

4. This Agreement is effective as of December 23, 1997.

5. All defined terms not defined herein are used as defined in the Subscription
Agreement and the Statement.

6. The Company shall pay the Buyer's reasonable expenses, including attorney's

Company, the Buyer and such other parties. This Agreement shall be governed by

8. This Agreement may be executed in counterparts and by the parties hereto on
separate counterparts, all of which together shall constitute one and the same
instrument. A telephone line facsimile copy of this Agreement bearing a
signature on behalf of a party hereto shall be legal and binding on such party.

the Statement are hereby confirmed. The parties further confirm that the terms

Approval or listing, as the case may be, the Company shall issue promptly all
shares of Common Stock due through the date of such issuance.

For purposes of this Agreement, the term "Share Limitation Event" means a time
at which the Company is unable to redeem all shares of Preferred Stock otherwise
required to be redeemed pursuant to Section 4(a) of the Statement by reason of
events which are not solely within the control of the Company.

        (d) For purposes of this Agreement, (A) an Optional Redemption Event
described in clause (1), (2) or (5) of the definition of the term "Optional
Redemption Event" or (B) a requirement of the Company to redeem shares pursuant
to Section 4(a) of the Statement shall be deemed to have occurred by reason of
events which are not solely within the control of the Company if a requirement
of the Company to redeem, or a right of any holder of shares of Preferred Stock
to require redemption of, shares of Preferred Stock by reason thereof, would
result in the Company being required to classify the Preferred Stock as
redeemable preferred stock on a balance sheet of the Company prepared in
accordance with generally accepted accounting principles and Regulation S-X of
the SEC.

        (e) For purposes of this Agreement, the term "Auditor's Determination"
shall mean a written determination signed by the Auditors concurring with the
Company's conclusion that (A) the Optional Redemption Event described in the
applicable clause (1), (2) or (5) of the definition of Optional Redemption Event
in Section 8(a) of the Statement or (B) a requirement of the Company to redeem
shares pursuant to Section 4(a) of the Statement, was due to the occurrence of
events which were not solely within the control of the Company, as such phrase
is defined in Subsection (d) immediately above. The Auditor's Determination
shall (i) set forth in reasonable detail all relevant facts considered by the
Auditors in connection therewith, (ii) set forth all applicable accounting
principles and assumptions used, and (iii) set forth in reasonable detail or
attach copies of all legal, expert and other advice or information used by the
Auditors in reaching their conclusion. To the extent any facts are assumed for
purposes of the Auditor's Determination, the validity of such conclusion or
determination shall depend upon such assumed facts being true and complete in
all material respects.

                                WAIVER AGREEMENT

        THIS WAIVER AGREEMENT, dated as of June 30, 1998, is by and between TERA
COMPUTER COMPANY, a Washington corporation (the "Company"), and GENESEE FUND
LIMITED - PORTFOLIO B., a British Virgin Islands corporation (the "Buyer").

        WHEREAS, the Company and the Buyer entered into a Subscription
Agreement, dated as of June 30, 1998 (the "Subscription Agreement"), pursuant to
which the Company issued to the Buyer certain shares of the Company's Series B
Convertible Preferred Stock, $.01 par value ("Preferred Stock"), and warrants to
purchase shares of the Company's common stock, $.01 par value ("Common Stock"),
and in connection therewith the Company and the Buyer entered into a
Registration Rights Agreement, dated as of June 30, 1998 (the "Registration
Rights Agreement"); and

        WHEREAS, the Company and the Buyer have been informed that certain
provisions of the Statement of Rights and Preferences of the Preferred Stock
(the "Statement") may be construed, under generally accepted accounting
principles and rules and regulations of the Securities and Exchange Commission,
as requiring that the Company classify the shares of Preferred Stock issued to
the Buyer as "redeemable" shares of Preferred Stock on the Company's financial
statements; and

        WHEREAS, neither the Company nor the Buyer intended that the shares of
Preferred Stock issued to the Buyers be so classified; and

        WHEREAS, the parties desire to correctly state their intent and
understanding;

        NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants contained herein, the parties hereby agree as follows:

1. (a) Notwithstanding Sections 4 and 8 and any other provision of the
Statement, if (A) an Optional Redemption Event occurs by reason of the
occurrence of an event described in clause (1), (2) or (5) of Section 8(a) of
the Statement, or (B) the Company is required to redeem shares of Preferred
Stock by reason of the occurrence of an event described in Section 4(a) of the
Statement, and such occurrence is by reason of events which are not solely
within the control of the Company, then the Company, in its sole discretion, may
elect not to redeem any or all of the shares of Preferred Stock and, if the
Company so elects, then the Buyer hereby waives any and all rights to require
the Company to so redeem such shares of Preferred Stock under such provisions.
In order to make such election, the Company shall so notify the 



                                       1
<PAGE>   2

Buyer which has given either an Optional Redemption Notice or has given a notice
to the Company directing the Company to redeem shares of Preferred Stock
pursuant to Section 4(a)(2) (an "Inconvertibility Redemption Notice"), as the
case may be, and shall deliver to the Buyer an Auditor's Determination (as
defined below) within ten (10) Business Day's after the Company's receipt of an
Optional Redemption Notice or an Inconvertibility Redemption Notice.

        (b) If the Company so elects and notifies the Buyer, then, for each
thirty (30) days that such Optional Redemption Event or Share Limitation Event
(as defined below), as the case may be, continues to exist, commencing as of the
first Business Day of the event which gave rise to such Optional Redemption
Event or such Share Limitation Event, the Conversion Percentage shall be
permanently reduced by six percentage points and the Ceiling Price shall be
permanently reduced by six percent of the amount the Ceiling Price otherwise
would have been without any reduction pursuant to this clause (such Conversion
Percentage and Ceiling Price reduction shall be pro rated for any period of, or
in case the Optional Redemption Event or Share Limitation Event ceases to exist
in, less than thirty (30) days), provided that the Conversion Percentage and
Ceiling Price shall not be so reduced if the Company duly and timely issues a
Shareholder Approval Notice and obtains Shareholder Approval pursuant to Section
4 of the Statement.

        (c) With respect to a Share Limitation Event, on or after the date the
Company gives a Shareholder Approval Notice, the Company promptly shall call a
special meeting of its shareholders, to be held not later than 60 days after
such Notice is given, to seek the Shareholder Approval for the issuance of all
shares of Common Stock issuable in accordance with the Statement and this
Agreement without regard to Rule 4460(i) of Nasdaq or any similar or successor
provision (the "Rule") and shall use its best efforts to obtain the Shareholder
Approval. The Company shall prepare and file with the SEC within 20 days after
such notice is given preliminary proxy materials which set forth a proposal to
seek such Shareholder Approval. The Company shall provide the Buyer an
opportunity to consult with the Company regarding the content of such proxy
materials insofar as it relates to the Shareholder Approval by providing copies
of such preliminary proxy materials and any revised preliminary proxy materials
to the Buyer a reasonable period of time prior to their filing with the SEC. The
Company shall furnish to the Buyer a copy of its definitive proxy materials for
such special meeting and any amendments or supplements thereto promptly after
the same are mailed to shareholders or filed with the SEC. Upon the earlier of
(i) the failure to obtain the Shareholder Approval at the special meeting or
(ii) the failure to hold the special meeting within such 60-day period, the
Company shall so notify the Buyer and such of the following as shall be
specified by notice to the Company from the Buyer shall occur: (1) the
Conversion Percentage and the Ceiling Price shall be reduced pursuant to



                                       2
<PAGE>   3

Subsection (b) above and (2) the Company shall promptly file applications and
take all other actions necessary to (i) list the Common Stock for trading and
quotation on the OTC Bulletin Board or such other securities market or exchange
which will not restrict the number of shares of Common Stock issuable under this
Agreement and (ii) upon filing such applications, request the immediate removal
of the Common Stock from listing on the securities market on which it is then
listed which restricts the issuance of shares of Common Stock under this
Agreement without the Shareholder Approval. Upon obtaining such Shareholder
Approval or listing, as the case may be, the Company shall issue promptly all
shares of Common Stock due through the date of such issuance.

For purposes of this Agreement, the term "Share Limitation Event" means a time
at which the Company is unable to redeem all shares of Preferred Stock otherwise
required to be redeemed pursuant to Section 4(a) of the Statement by reason of
events which are not solely within the control of the Company.

        (d) For purposes of this Agreement, (A) an Optional Redemption Event
described in clause (1), (2) or (5) of the definition of the term "Optional
Redemption Event" or (B) a requirement of the Company to redeem shares pursuant
to Section 4(a) of the Statement shall be deemed to have occurred by reason of
events which are not solely within the control of the Company if a requirement
of the Company to redeem, or a right of any holder of shares of Preferred Stock
to require redemption of, shares of Preferred Stock by reason thereof, would
result in the Company being required to classify the Preferred Stock as
redeemable preferred stock on a balance sheet of the Company prepared in
accordance with generally accepted accounting principles and Regulation S-X of
the SEC.

        (e) For purposes of this Agreement, the term "Auditor's Determination"
shall mean a written determination signed by the Auditors concurring with the
Company's conclusion that (A) the Optional Redemption Event described in the
applicable clause (1), (2) or (5) of the definition of Optional Redemption Event
in Section 8(a) of the Statement or (B) a requirement of the Company to redeem
shares pursuant to Section 4(a) of the Statement, was due to the occurrence of
events which were not solely within the control of the Company, as such phrase
is defined in Subsection (d) immediately above. The Auditor's Determination
shall (i) set forth in reasonable detail all relevant facts considered by the
Auditors in connection therewith, (ii) set forth all applicable accounting
principles and assumptions used, and (iii) set forth in reasonable detail or
attach copies of all legal, expert and other advice or information used by the
Auditors in reaching their conclusion. To the extent any facts are assumed for
purposes of the Auditor's Determination, the validity of such conclusion or
determination shall depend upon such assumed facts being true and complete in
all material respects.

Agreement in reliance upon the exemption from securities registration afforded

<PAGE>   2

               (d) "Adjustment Shares" means the shares of Common Stock issuable
by the Company to the Buyers pursuant to Section 3 hereof and any other

exchanged pursuant to a plan of recapitalization, reorganization, merger, sale
of assets or otherwise.

               (e) "Business Day" means any day other than a Saturday, Sunday or

               (f) "Closing Date" means September 30, 1998 or such other date as
to which the parties hereto may agree.

               (g) "Closing Price" of the Common Stock on any date means the
closing bid price for one share of Common Stock on such date on the first
applicable among the following: (a) the national securities exchange on which
the shares of Common Stock are listed which constitutes the principal securities
market for the Common Stock, (b) the Nasdaq, if the Nasdaq constitutes the
principal market for the Common Stock on such date, or (c) the Nasdaq SmallCap,
if the Nasdaq SmallCap constitutes the principal securities market for the
Common Stock on such date, in any such case as reported by Bloomberg, L.P.;
provided, however, that if during any Measurement Period or other period during
which the Closing Price is being determined:

                      (i) The Company shall declare or pay a dividend or make a
distribution to all holders of the outstanding Common Stock in shares of Common
Stock or fix any record date for any such action, then the Closing Price for
each day in such Measurement Period or such other period which day is 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 Closing Price
(determined without regard to this proviso) for each such day in such
Measurement Period or such other period by a fraction, the numerator of which
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 of which shall be the
sum of such number of shares and the total number of shares constituting such
dividend or other distribution;

                      (ii) The Company 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 Closing Price
(determined without regard to this proviso) for any day in such Measurement
Period or such other period which day is prior to the end of such 45-day period,
then the Closing Price



                                       -2-
<PAGE>   3
for each such day shall be reduced so that the same shall equal the price
determined by multiplying the Closing Price (determined without regard to this
proviso) by a fraction, the numerator of which 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 Closing Price, and the denominator
of which 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 Closing 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 cash, to
be determined in good faith by a resolution of the Board of Directors of the
Company;

                      (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 Closing Price of the Common Stock
for each day in such Measurement Period or such other period which day is 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 Closing Price for each day in such
Measurement Period or such other period which day is prior to the earlier of (1)
the date on which such combination becomes effective and (2) the date on which
trading in the Common Stock on a basis which gives effect to such combination
begins, shall be proportionately increased;

                      (iv) The Company shall, by dividend or otherwise,
distribute to all holders of its Common Stock shares of any class of capital
stock of the Company (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 Closing Price for each
day in such Measurement Period or such other period which day is 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 Closing Price (determined without regard to this proviso) by a
fraction, the numerator of which shall be the Closing Price (determined without
regard to this proviso) for such trade less the fair market value (as determined
in good faith by resolution of the Board of Directors of the Company) 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 of which shall be
the Closing



                                       -3-

<PAGE>   4

Price (determined without regard to this proviso). If the Board of Directors of
the Company 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 Closing 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 (i) or (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 (i) or (ii) of this proviso applies (and any Closing 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 Closing 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 Company or any subsidiary of the Company 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 (other than an Option Share Surrender) 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 after the Closing Date and within the twelve (12) months
preceding the date of 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 Company) of consideration paid in
respect of any repurchase or other reacquisition by the Company or any
subsidiary of the Company of any shares of Common Stock (other than an Option
Share Surrender) made after the Closing Date and 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 Company) of consideration payable in respect of any
Tender Offer by the Company 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 (such aggregate amount combined with the

product of the Closing Price (determined without regard to this proviso) for any
day in such Measurement Period or such other period which day is prior to the
earlier of (A) the record date with respect to such distribution and (B) 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 Closing Price for each such day shall be
reduced so that the same shall equal the price determined by multiplying the
Closing Price (determined without regard to this proviso) for such day by a
fraction (i) the numerator of which shall be equal to the Closing 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 Closing Price (determined without
regard to this proviso) for such day; or

                      (vi) A Tender Offer made by the Company or any of its
subsidiaries 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 Company) 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 Company), as of the
expiration of such Tender Offer, of consideration payable in respect of any
other Tender Offers, by the Company or any of its subsidiaries for all or any
portion of the Common Stock expiring within the 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 Company) of consideration paid in respect of any repurchase or
other reacquisition by the Company or any subsidiary of the Company of any
shares of Common Stock (other than an Option Share Surrender) made after the
Closing Date and within the 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, and (3) the aggregate amount of any distributions to all
holders of Common Stock made exclusively in cash within 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
Closing Price (determined without regard to this proviso) for any day in such
period times the number of shares of Common Stock outstanding on such day, then,
and in each such case, the Closing Price for such day shall be reduced so that
the same shall equal the price determined by multiplying the Closing Price
(determined without regard to this proviso) for such day by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding on
such day multiplied by the Closing Price (determined without regard to this
proviso) for such day and the denominator of which shall be the sum of (x) the
fair market value (determined as aforesaid) of the aggregate consideration
payable to shareholders

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 times the Closing
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 Closing Price

be made for such Tender Offer under this clause (vi) for such day.

<PAGE>   9

where:

               (b) SUBSEQUENT ISSUANCES OF ADJUSTMENT SHARES. On each subsequent

shall issue to each Buyer the number of Adjustment Shares calculated in
accordance with the following formula:

                          [ (1.0125 x A x C) / B ] - A

where:

A =  Number of Initial Shares and Adjustment Shares beneficially owned by Buyer 
     on the Adjustment Date,

B =  Adjustment Price applicable to the Adjustment Date, and 

C =  Lowest Adjustment Price for any prior Adjustment Date.


               (c) BUYER'S ASSIGNMENT OF RIGHTS UNDER SECTION 3. If a Buyer
intends to assign all or any portion of its rights to acquire any Adjustment
Shares in accordance with Section 10(h) hereof, then such Buyer shall so notify
the Company not less than ten days before any Adjustment Date. Each such notice
of assignment by a Buyer shall specify the name(s) of the assignee(s) and the
rights to be assigned thereto. Each such notice shall be executed by the
assignee(s). From and after the giving of such notice by such Buyer, the Buyer
shall be deemed for all purposes to have assigned to such assignee(s) the rights
under this Agreement with respect to the acquisition of the number of Adjustment
Shares covered by such notice, and such assignee(s) shall be deemed a party to
this Agreement with respect to the acquisition of such number of Adjustment
Shares upon the terms and subject to the conditions of this Agreement, and all
applicable references hereinafter to the "Buyers" shall include such
assignee(s).

               (d) NO FRACTIONAL SHARES. No fractional shares of Common Stock
shall be issued as Adjustment Shares but, in lieu of any fraction of a share of
Common Stock that would otherwise be issuable as Adjustment Shares, the Company
shall pay in cash an amount equal to the product of (i) the Adjustment Price and
(ii) such fraction of a share.

               (e) DELIVERY OF ADJUSTMENT SHARES. The Company shall issue and
deliver to each Buyer certificates for the Adjustment Shares not later than 4:00

for the Adjustment Shares shall be made at



                                       -9-

<PAGE>   10

a location mutually agreed to by the parties hereto. In lieu of delivering
physical certificates representing the Adjustment Shares, provided that the
Company's transfer agent is participating in the Depository Trust Company
("DTC") Fast Automated Securities Transfer program, upon request of a Buyer, the
Company shall cause its transfer agent to electronically transmit such
Adjustment Shares by crediting the account of such Buyer or the Buyer's broker
with the DTC through its Deposit Withdrawal Agent Commission system. The
Company's obligation to issue and deliver the certificates for Common Stock
representing the Adjustment Shares shall be absolute and unconditional,
irrespective of any action or inaction by the Buyer to enforce the same, any
waiver or consent with respect to any provision hereof, 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 Buyer, or
any setoff, counterclaim, recoupment, limitation or termination, or any breach
or alleged breach by the Buyer or any other person of any obligation to the
Company or any violation or alleged violation of law by the Buyer or any other
person, and irrespective of any other circumstance which might otherwise limit
such obligation of the Company to the Buyer in connection with such obligation.
If the Company fails to issue and deliver the certificates for the Common Stock
pursuant to this Section 3(e) as and when required to do so following each
Adjustment Date, in addition to any other liabilities the Company may have
hereunder and under applicable law (1) the Company shall pay or reimburse the
Buyer on demand for all reasonable out-of-pocket expenses including, without
limitation, fees and expenses of legal counsel incurred by the Buyer as a result
of such failure, and (2) the Adjustment Price used to determine the number of
Adjustment Shares due with respect to such Adjustment Date shall be reduced by
two percent from the Adjustment Price otherwise used to calculate such number of
Adjustment Shares for each Trading Day the Company fails to issue and deliver
such certificates and, accordingly, the Buyer shall be entitled to receive the
additional Adjustment Shares resulting from such reduced Adjustment Price.

               (f) CONDITION PRECEDENT TO ISSUANCE OF ADJUSTMENT SHARES. Each
Buyer understands that the Company's obligation to issue the Adjustment Shares
to such Buyer in accordance with this Agreement is conditioned upon the accuracy
in all material respects on the Adjustment Date of the representations and
warranties of the Buyer contained in Sections 4(a), (b), (c), (d), (f) and (g)
of this Agreement as if made on the Adjustment Date.

               (c) REOFFERS AND RESALES. All subsequent offers and sales of the

from the registration 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 Initial Shares and the Warrants and to receive an offer of the
Adjustment 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
Initial Shares and the Warrants and the offer of the Adjustment Shares, that
have been requested by the Buyer. The Buyer and its advisors, if any, have been
afforded the opportunity to ask questions of the management of the Company and
have received complete and satisfactory answers to any such inquiries. Without
limiting the generality of the foregoing, the Buyer has had the opportunity to
obtain and to review the Disclosure Documents.

               (f) ABSENCE OF APPROVALS. The Buyer understands that no United
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Securities.

               (g) SUBSCRIPTION AGREEMENT. This Agreement has been duly and
validly authorized, executed, and delivered on behalf of the Buyer and is a
valid and binding agreement of the Buyer enforceable in accordance with its
terms, subject to general principles of equity and to bankruptcy, insolvency,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally.

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

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 of Series B 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 Schedule 5(b) hereof. The outstanding shares of
Common Stock and outstanding options, warrants, and other securities to purchase

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 Agreements).

               (c) CONCERNING THE SECURITIES. The Securities have been duly
authorized and the Initial Shares, when issued and paid for in accordance with
this Agreement, the Adjustment Shares, when issued, and the Warrant Shares, when
issued 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 Common Shares. The Common Stock is listed for
trading on the Nasdaq and, except as set forth in Schedule 5(c), (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

reason that the Common Shares will not be eligible for listing on Nasdaq.

AGREEMENTS. This Agreement, the Warrants, and the Registration Rights Agreements
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

by the Company, will be, valid and binding obligations of the Company
enforceable in accordance with their respective terms, subject 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.

Agreement by the Company and the issuance by the Company of the Initial Shares,
the Adjustment Shares, the Warrants, and the Warrant Shares, as contemplated by
this Agreement, and completion of the other transactions contemplated in this
Agreement, the Registration Rights Agreements 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 and Amended 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

effect on the Company.

prospects of the Company, and, except as and to the extent disclosed, reflected
or reserved against in the financial statements of the Company and the notes
thereto included in the Disclosure Documents, the Company has no material

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 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,



                                      -14-

<PAGE>   15

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 confidential treatment of information and to the
knowledge of the Company, no such request will be made by the Company prior to
the time the Registration Statement relating to the Initial Shares which is
contemplated by the Registration Rights Agreements is first ordered effective by
the SEC; and, to the knowledge of the Company, 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 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 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. The Company does not have any knowledge of, and the Company has not
given or received any notice of, any pending conflicts with or infringement of
the rights of others with respect to any Company Proprietary Rights (as defined
herein) or with respect to any license of Company Proprietary Rights. No action,
suit, arbitration, or legal, administrative or other proceeding or investigation
is pending, or, to the best knowledge of the Company, threatened, which involves
any Company Proprietary Rights. The Company is not subject to any judgment,
order, writ, injunction or decree of any court or any federal, state, local,
foreign or other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, or any arbitrator, or has entered into or
is a party to any contract which restricts or impairs the use of any such
Company Proprietary Rights in a manner which would have a material adverse
effect on the use by the Company of any of the Company Proprietary Rights. To
the best knowledge of the Company, no Company Proprietary Rights and no services
or products sold by the Company, conflict with or infringe upon any proprietary
rights available to any third party. The Company has not received written notice
of any pending conflict with or infringement upon such third-party proprietary
rights. The Company has not entered into any consent, indemnification,
forbearance to sue or settlement agreement with respect to Company Proprietary
Rights other than in the ordinary course of business. No claims have been
asserted by any person with respect to the validity of the Company's ownership
or right to use the Company Proprietary Rights and, to the best knowledge of the
Company, there is no reasonable basis for any such claim to be successful. To
the best knowledge of the Company, the Company Proprietary Rights are valid and
enforceable. No registration relating to the Company Proprietary Rights has
lapsed, expired or been abandoned or



                                      -15-
<PAGE>   16

canceled or is the subject of cancellation or other adversarial proceedings, and
all applications therefor are pending and are in good standing, except for such
lapses, expirations, abandonments, cancellations, adversarial proceedings or
failures to be in good standing which would not, singly or in the aggregate,
have a material adverse effect on the business, properties, operations,
condition (financial or otherwise), results of operations or prospects of the
Company. The Company has complied, in all material respects, with its
contractual obligations relating to the protection of the Company Proprietary
Rights used pursuant to licenses. To the best knowledge of the Company, no
person is infringing on or violating the Company Proprietary Rights. As used
herein, the term "Company Proprietary Rights" means all patents, patent
applications, inventions, trademarks, trade names, applications for registration
of trademarks, service marks, service mark applications, copyrights, know-how,
manufacturing processes, formulae, trade secrets, licenses and rights in any
thereof and any other intangible property and assets which are material to the
business of the Company as now conducted, as proposed to be conducted or as
described in this Agreement.

               (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. The Company has not filed any
reports with the SEC under the 1934 Act since January 22, 1998, other than the
Disclosure Documents.

               (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 each Buyer harmless from, any claim made against
such Buyer by any person for any such commission, 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.

               (o) NO SOLICITATION. No form of general solicitation or general
advertising was used by the Company or, to the best of its knowledge, any other
person acting on behalf of the Company, in respect of or in connection with the
offer and sale of the Securities. Neither the Company nor, to its knowledge, any
person acting on behalf of the Company has, either directly or indirectly, sold
or offered for sale to any person any of the Common Shares or the Warrants or,
within the six months prior to the date hereof, any other similar security of
the Company except as contemplated by this Agreement; and neither the



                                      -16-

<PAGE>   17

Company nor any person authorized to act on its behalf will sell or offer for
sale any shares of Common Stock or Warrants, or solicit any offers to buy any
shares of Common Stock or Warrants, so as thereby to cause the issuance or sale
of any of the Common Shares or the issuance of the Warrants to be in violation
of Section 5 of the 1933 Act.

               (p) CERTAIN ISSUANCES OF SECURITIES. The Company has not issued
any shares of Common Stock or shares of any series of preferred stock or other
securities convertible into, exchangeable for or otherwise entitling the holder
to acquire shares of Common Stock which are subject to Rule 4460(i) of Nasdaq
(or any successor, replacement or similar provision thereof or of any other
market on which the Common Stock is listed for trading) and which would be
integrated with the sale of the Initial Shares to the Buyers or the issuance of
Adjustment Shares or Warrant Shares for purposes of such Rule 4460(i) (or any
successor, replacement or similar provision thereof or of any other market on
which the Common Stock is listed for trading), other than the Company's Series B
Convertible Preferred Stock.

        6.     CERTAIN COVENANTS AND ACKNOWLEDGMENTS

               (a) TRANSFER RESTRICTIONS. Each Buyer acknowledges that (i) the
Warrants have not been and are not being registered under the 1933 Act, and,
except as provided in the Registration Rights Agreements, the Common Shares have
not been and are not being registered under the 1933 Act, and may not be
transferred unless (x) subsequently registered thereunder or (y) such 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 Agreements) under the 1933 Act or to comply with the terms and conditions
of any exemption thereunder (other than pursuant to Section 6(d) hereof and
pursuant to the Registration Rights Agreements).

               (b) RESTRICTIVE LEGEND. Each Buyer acknowledges and agrees that
the certificates for the Initial Shares, the Adjustment Shares, the Warrants,
and the Warrant Shares and, until such time as the Common Shares have been
registered under the 1933 Act as contemplated by the Registration Rights
Agreements, the certificates for the Common Shares shall 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):



                                      -17-

<PAGE>   18

                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 Agreements has been declared effective,
thereafter (i) upon request of a Buyer the Company will substitute certificates
without the above-referenced legend for certificates for any Common Shares
issued prior to the date such Registration Statement is declared effective by
the SEC which bear such legend and promptly remove any stop-transfer restriction
relating to such Common Shares, but in no event later than three Business Days
after surrender of such certificates by such Buyer, and (ii) the Company shall
not place any restrictive legend on certificates for any Common Shares issued or
impose any stop-transfer restriction thereon.

               (c) REGISTRATION RIGHTS AGREEMENTS. The Company and each Buyer
agree to enter into a 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 Buyers promptly after such filing.
Each Buyer agrees to cooperate with the Company in connection with such filing
and, upon request of the Company, to provide all information relating to such
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 Agreements), the Company shall file a listing application for the Common
Shares with the Nasdaq and shall provide evidence of such filing to each 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



                                      -18-

<PAGE>   19

of sale of the Common 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 from qualification for, the Initial Shares for sale to the Buyers
pursuant to this Agreement and the Warrants, and the Adjustment Shares and the
Warrant Shares for issuance to the Buyers, under such of the securities or "blue
sky" laws of jurisdictions as shall be applicable to the offer and sale of the
Initial Shares, the issuance of the Warrants, and the offer of the Adjustment
Shares pursuant to this Agreement. 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 Buyers withing five days
of filing or receipt thereof, as the case may be.

               (h) CERTAIN EXPENSES AND FEES. Whether or not the closing of the
transactions contemplated hereby occurs, the Company shall pay or reimburse the
Buyers for all reasonable expenses (including, without limitation, legal fees
and expenses of counsel to the Buyers of up to $20,000) incurred by the Buyers
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 Buyers, and
the Buyers shall pay on demand all expenses (including reasonable attorneys'
fees and expenses) incurred by the Company, as a consequence of, or in
connection with, (i) any default or breach of any of the other party's
obligations under this Agreement, the Warrants, and the Registration Rights
Agreements (which payment shall be made by the defaulting or breaching party),
and (ii) the enforcement or restructuring of any right of, including the
collection of any payments due, the Buyers 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 Buyers, as the case may be, from paying any
amount due the Buyers or the Company, as the case may be, in which the party
seeking such enforcement or restructuring prevails.

               (i)    CERTAIN ISSUANCES OF SECURITIES.

                      (i) Unless the Company obtains the Shareholder Approval
(as defined in Section 6(i)(2) below) or a waiver thereof from Nasdaq, the
Company will not issue any shares of Common Stock or shares of any 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 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 Initial Shares to the Buyers, or the issuance of Adjustment Shares or
Warrant Shares to the Buyers, or the sale and issuance of the Series B Stock and
the common stock purchase warrants issued in connection therewith (including the
issuance of shares of Common Stock upon conversion of the Series B Stock or in
payment of dividends thereof, and upon exercise of the aforesaid common stock
purchase 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).

                      (ii) For purposes of this Agreement, "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 Company (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 Company of 20% or more of the
outstanding Common Stock of the Company for less than the greater of the book or
market value of such Common Stock, taking into account all issuances of Common
Stock to the Buyers on the Closing Date, on all Adjustment Dates, and upon the
exercise of the Warrants, as and to the extent required under Rule 4460(i) of
Nasdaq as in effect from time to time or any successor or replacement provision
thereof or of any similar provision of any other market on which the Common
Stock is listed for trading.

                      (iii) During the period from the Closing Date to the later
of the date on which the Registration Statement shall have been effective with
the SEC for 60 consecutive days or the Initial Adjustment Date, 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 at a price below the Market Price of the Common Stock;
provided, however, that nothing in this Section 6(i)(3) 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.



                                      -20-

<PAGE>   21

               (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 Initial Shares set forth in Section 8 or 9, as the case
may be, of this Agreement on the Closing Date.

               (k) CERTAIN TRADING RESTRICTIONS. So long as the Company is in
compliance in all material respects with its obligations to the Buyer pursuant
to this Agreement, the Registration Rights Agreements and the Warrants, each
Buyer agrees that it and its affiliates shall not engage in short sales or other
hedging transactions relating to the Common Stock (i) during the 18 Trading Days
prior to the Initial Adjustment Date unless and only while the then highest
current bid price of the Common Stock, as reported on Nasdaq, is higher than
125% of the Floor Price, and (ii) during the 18 Trading Days prior to any other
Adjustment Date unless and only while the then highest current bid price of the
Common Stock, as reported on Nasdaq, is higher than 125% of the then applicable
lowest Adjustment Price for any prior Adjustment Date. To the extent that any
prior agreement between the Company and the Buyers otherwise permits short sales
or other hedging transactions, any such sale and transaction shall conform to
the provisions of the foregoing sentence, except as otherwise provided below
with respect to the Preferred Stock Subscription Agreements. To the extent that
the first sentence of this Section 6(k) permits short sales or other hedging
transactions, then 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 (assuming that the exclusions in subparagraph (e) of Rule 10a-1 are
inapplicable), and in any case such transactions will not create any daily low
sales prices for the Common Stock. The foregoing notwithstanding, nothing herein
shall prohibit Advantage from entering into a short sale or other hedging
transaction involving a number of shares of Common Stock not in excess of the
number of shares for which it has submitted a conversion notice to the Company
and its transfer agent pursuant to its respective Subscription Agreements, dated
as of December 23, 1997 and June 30, 1998, with the Company (the "Preferred
Stock Subscription Agreements").

               (l) RESERVATION OF COMMON STOCK. The Company (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 issuance of all Adjustment
Shares and Warrant Shares issuable hereunder are at all times reserved by the
Company (or any successor corporation), free from preemptive rights. If the
Company shall issue any securities or make any change in its capital structure
which would change the number of shares of Common Stock issuable as Adjustment
Shares or Warrant Shares as herein provided, the Company 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 issuance of the Common Shares on the new basis. If at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to permit
the issuance of all Adjustment Shares and Warrant Shares issuable hereunder, the
Company promptly shall seek, and use its



                                      -21-

<PAGE>   22

best efforts to obtain and complete, 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.

               (m) CONSOLIDATION, MERGER, ETC. In case of any consolidation or
merger of the Company with any other corporation (other than a wholly-owned
subsidiary of the Company) in which the Company is not the surviving
corporation, or in case of any sale or transfer of all or substantially all of
the assets of the Company, 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 Company shall make appropriate provision or cause
appropriate provision to be made so that each holder of Common Shares then
outstanding shall have the right thereafter to receive Adjustment Shares in the
form of 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 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 rights of the holders of Common Shares to
receive Adjustment Shares on a basis as nearly as practical as such rights exist
hereunder prior thereto. The Company shall not effect any such transaction
unless the provisions of this Section 6(m) have been complied with. The above
provisions shall similarly apply to successive consolidations, mergers, sales,
transfers, or share exchanges.

               (n) OVERDUE AMOUNTS. Whenever any amount which is due by the
Company to any holder of Common Shares pursuant to the terms of this Agreement,
the Registration Rights Agreements or the Warrants is not paid to such holder
when due, such amount shall bear interest at the rate of 14% per annum (or such
other rate as shall be the maximum rate allowable by applicable law) until paid
in full.

        7.     BUYERS' RIGHT TO REQUIRE REPURCHASE OF THE COMMON SHARES

               (a) REPURCHASE AT OPTION OF BUYERS. Each Buyer shall be entitled,
at its option by notice to the Company given within 90 days after the occurrence
of a Repurchase Event (as defined in Section 7(b)), to require the Company to
repurchase all or a portion of its Common Shares following the occurrence of a
Repurchase Event.

               (b) REPURCHASE EVENTS. A "Repurchase Event" means any one of the
following events:

                      (i) For any period of five consecutive Trading Days there
shall be no reported closing bid price of the Common Stock on any national
securities exchange, the Nasdaq or on the Nasdaq SmallCap Market;



                                      -22-

<PAGE>   23

                      (ii) The Common Stock ceases to be listed for trading on
the Nasdaq, the Nasdaq SmallCap Market, the New York Stock Exchange, or the
American Stock Exchange;

                      (iii) The inability for 30 or more days (whether or not
consecutive) of any holder of Common Shares who is entitled to exercise its
repurchase right under this Section 7 to sell such Common Shares pursuant to the
Registration Statement for any reason on each of such 30 days, other than for an
Excluded Period as defined in the Registration Rights Agreements;

                      (iv) The Company shall fail or default in the timely
performance of any material obligation to the Buyer under the terms of this
Agreement, the Warrants, the Registration Rights Agreements or any other
agreement or document entered into in connection with the transactions
contemplated hereby, as such instruments may be amended from time to time,
provided such failure or default is not cured prior to the delivery of an
Repurchase Notice (as defined in Section 7(c)); or

                      (v) Any consolidation or merger of the Company with or
into another entity (other than a merger or consolidation of a subsidiary of the
Company into the Company or a wholly-owned subsidiary of the Company) where the
shareholders of the Company immediately prior to such transaction do not
collectively own at least 51% of the outstanding voting securities of the
surviving corporation of such consolidation or merger immediately following such
transaction or the common stock of such surviving corporation is not listed for
trading on the Nasdaq, the Nasdaq SmallCap Market, the New York Stock Exchange,
or the American Stock Exchange.

               (c) REPURCHASE NOTICE. To exercise the right of repurchase under
Section 7(a), a Buyer shall deliver to the Company a notice of repurchase (a
"Repurchase Notice"), accompanied by the certificate(s) for the Common Shares to
be repurchased. Any Repurchase Notice shall state (i) that such Buyer is thereby
requiring the Company to repurchase Common Shares pursuant to this Section 7,
(ii) the Repurchase Event giving rise to such repurchase, and (iii) the number
of Common Shares which are to be repurchased. Promptly and in no event later
than three Business Days after the Company's receipt of the Repurchase Notice,
the Company shall make payment in immediately available funds of the Repurchase
Price (as defined in Section 7(d)) applicable on the date of such repurchase
with respect to the Common Shares to be repurchased to or upon the order of the
Buyer as specified in the Repurchase Notice. Upon repurchase of less than all of
the Common Shares evidenced by a particular certificate, promptly, but in no
event later than three Business Days after surrender of such certificate to the
Company, the Company shall issue a replacement certificate for the Common Shares
that have not been repurchased. Only whole Common Shares may be repurchased.



                                      -23-

<PAGE>   24

               (d) REPURCHASE PRICE. As used herein, "Repurchase Price" means
(1) during the period from the Closing Date through and including the Initial
Adjustment Date, the product of (i) the number of Common Shares to be
repurchased and (ii) the Floor Price, and (2) after the Initial Adjustment Date,
the product of (i) the number of Shares to be repurchased and (ii) the greater
of (x) the arithmetic average of the Market Price of the Common Stock for the
five consecutive Trading Days ending on the Trading Day immediately preceding
the date of repurchase and (y) the most recent Adjustment Price.

               (e) THIRD PARTY REPURCHASE RIGHTS. Each Buyer acknowledges that
holders of outstanding securities of the Company issued pursuant to the
Preferred Stock Subscription Agreements (including Advantage and its affiliates)
are entitled to have their securities repurchased or redeemed by the Company
upon the occurrence of certain events, including but not limited to events
substantially similar to the Repurchase Events, and that such obligations of the
Company to repurchase securities held by third parties may affect the Company's
ability to pay any Repurchase Price due under this Agreement.

               (f) INABILITY TO ISSUE ADJUSTMENT SHARES. In the event the
Company is unable to issue all Adjustment Shares required to be issued with
respect to any Adjustment Date by reason of the restrictions set forth in 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) (collectively, the "Rule"), each Buyer shall be entitled, at its
option, by notice to the Company given within 90 days after such Adjustment
Date, to require the Company to make a payment to such Buyer in an amount equal
to the product of (i) the number of Adjustment Shares otherwise required to be
issued to each Buyer on such Adjustment Date which the Company is unable to
issue by reason of the Rule and (ii) the Repurchase Price. Promptly and in no
event later than three Business Days after the Company's receipt of such notice,
the Company shall make a cash payment in immediately available funds of such
Repurchase Price to or upon the order of such Buyer unless prior thereto the
Company notifies such Buyer that it is seeking Shareholder Approval to permit
the issuance of all required Adjustment Shares in accordance with the Rule. If
the Company so elects to seek such Shareholder Approval and for any reason such
approval is not obtained within 60 days of the applicable Adjustment Date, the
Company shall be obligated to pay such Buyer the amount due pursuant to this
Section 7(f) within three Business Days after such 60th day. The Company's
obligations to make payments pursuant to this Section 7(f) shall not limit or
otherwise affect its obligations to repurchase Common Shares pursuant to the
other provisions of this Section 7.

               (g) LIMITATIONS ON REPURCHASES BY THE COMPANY. Notwithstanding
the foregoing, the Company's obligation to repurchase a Buyer's Common Shares
upon the occurrence of a Repurchase Event shall be subject to (i) the
restrictions on the Company's ability to purchase, redeem or otherwise acquire
any shares of its Common Stock as may be set forth in the Company's Amended and
Restated Articles of Incorporation, including the Statement of Rights and
Preferences for the Series A Stock and for the Series B Stock, and

                      (ii) the limitations on distributions to shareholders set
forth in the Washington Business Corporation Act. The Company agrees that it
will not amend its Restated Articles of Incorporation to limit or prohibit the
Buyers' rights to have their Common Shares repurchased pursuant to this
Agreement.

                               AMENDMENT AGREEMENT

        THIS AMENDMENT AGREEMENT, dated as of September 30, 1998, is by and
among TERA COMPUTER COMPANY, a Washington corporation (the "Company"), and
ADVANTAGE FUND II LTD., a British Virgin Islands corporation ("Advantage"), and
KOCH INDUSTRIES, INC., a Kansas corporation ("Koch" and, collectively with
Advantage, the "Buyers").

        WHEREAS, the Company and the Buyers entered into a Subscription
Agreement, dated as of September 30, 1998 (the "Subscription Agreement"),
pursuant to which the Company issued to the Buyers certain shares of the
Company's common stock, $.01 par value ("Common Stock"), and warrants to
purchase shares of Common Stock, and in connection therewith the Company and
each of the Buyers entered into separate Registration Rights Agreements, dated
as of September 30, 1998 (the "Registration Rights Agreements"); and

        WHEREAS, the Company and the Buyers have been informed that certain
provisions of the Subscription Agreement may be construed, under generally
accepted accounting principles and rules and regulations of the Securities and
Exchange Commission, as requiring that the Company classify the shares of Common
Stock issued or issuable to the Buyers as "redeemable" shares of Common Stock on
the Company's financial statements; and

        WHEREAS, neither the Company nor the Buyers intended that the shares of
Common Stock issued or issuable to the Buyers be so classified; and

        WHEREAS, the parties desire to correctly state their intent and
understanding;

        NOW THEREFORE, in consideration of the foregoing and of the mutual
covenants contained herein, the parties hereby agree as follows:

1. The Subscription Agreement is hereby amended by adding the following clauses
to the end of Section 7(b) thereof:

        "Notwithstanding Sections 7(a), 7(c) and any other provision of this
Agreement, if a Repurchase Event occurs by reason of the occurrence of an event
described in clause (i), (ii) or (v) of Section 7(b) above, and such occurrence
is by reason of events which are not solely within the control of the Company,
then the Company, in its sole discretion, may elect not to repurchase any or all
of the Common Shares and, if the Company so elects, each Buyer hereby waives any
and all rights to require the Company to so repurchase such Common Shares under
such clauses. In order to make such 



                                       1
<PAGE>   2

election, the Company shall so notify each Buyer which has submitted a
Repurchase Notice with respect to such event and shall deliver to each such
Buyer an Auditor's Determination (as defined below) within ten (10) Business
Days after the Company's receipt of the Repurchase Notice. If the Company so
elects and notifies each such Buyer, then for each thirty (30) days that such
Repurchase Event continues to exist, which period shall commence as of the first
Business Day of the event which gave rise to such Repurchase Event, the Company
shall issue to each such Buyer shares of Common Stock (the "Repurchase Shares")
equal to six percent (6%) of the number of Common Shares acquired hereunder and
beneficially held on the Determination Date (as defined below) by the Buyer (pro
rated for any period of, or in case the Repurchase Event ceases to exist in,
less than thirty (30) days). For purposes of this Section 7(b), a "Determination
Date" means the last day of each calendar month in which the Repurchase Event
continues. Such Repurchase Shares shall be issued by the Company within three
Business Days after each Determination Date. When issued and delivered to such
Buyer, the Repurchase Shares shall be duly authorized, validly issued, fully
paid and nonassessable.

        "For purposes of this Section 7, (A) a Repurchase Event described in
clause (i), (ii) or (v) of the definition of the term "Repurchase Event" in
Section 7(b) or (B) a requirement of the Company to make a payment pursuant
Section 7(f), shall be deemed to have occurred by reason of events which are not
solely within the control of the Company if a requirement of the Company to
repurchase, or a right of any holder of Common Shares to require repurchase of,
Common Shares pursuant to such clauses of Section 7(b), or the requirement of
the Company to make a payment pursuant to Section 7(f), would result in the
Company being required to classify the Common Shares as redeemable common stock
on a balance sheet of the Company prepared in accordance with generally accepted
accounting principles and Regulation S-X of the Securities and Exchange
Commission.

        "For purposes of this Section 7, the term "Auditor's Determination"
shall mean a written determination signed by the Auditors concurring with the
Company's conclusion that (A) the Repurchase Event described in the applicable
clause (i), (ii) or (v) of the definition of Repurchase Event in Section 7(b) or
(B) the requirement of the Company to make a payment pursuant to Section 7(f),
was due to the occurrence of events which were not solely within the control of
the Company, as such phrase is defined in the immediately preceding paragraph.
The Auditors' Determination shall (i) set forth in reasonable detail all
relevant facts considered by the Auditors in connection therewith, (ii) set
forth all applicable accounting principles and assumptions used, and (iii) set
forth in reasonable detail or attach copies of all legal, expert and other
advice or information used by the Auditors in reaching their conclusion. To the
extent any facts are assumed for purposes of the Auditor's Determination, the
validity of such conclusion or 



                                       2
<PAGE>   3

determination shall depend upon such assumed facts being true and complete in
all material respects.

        "For purposes of this Section 7, the term "Auditors" shall mean the
nationally recognized independent accounting firm then serving as the Company's
auditors or such other "big five" nationally recognized independent accounting
firm (including successors thereto) as the Company may designate. The fees and
expenses of the Auditors shall be paid by the Company."

2. The Subscription Agreement is hereby amended by adding a new Section 7(h) at
the end of Section 7 thereof:

               (h) SHARE LIMITATION EVENTS. Notwithstanding any other provision
of this Agreement, if a Share Limitation Event (as defined below) occurs by
reason of events which are not solely within the control of the Company, the
Company shall have the right to give a notice (a "Share Limitation Notice"),
accompanied by an Auditor's Determination, to the Buyer at any time after such
Share Limitation Event occurs and prior to the earlier of (1) the date on which
the Buyer's right (other than as limited by this Section 7(h)) to receive a cash
payment pursuant to Section 7(f) by reason of the occurrence of such Share
Limitation Event expires and (2) the date on which the Company is obligated to
make a payment to the Buyer pursuant to Section 7(f). If the Company timely
gives a Share Limitation Notice and an Auditor's Determination to the Buyer,
then, in lieu of making the payment required by Section 7(f) or issuing
Repurchase Shares pursuant to Section 7(b), pursuant to a notice given by the
Buyer by reason of such Share Limitation Event, on the next Adjustment Date to
occur the Adjustment Price shall be reduced to 80% of the amount such Adjustment
Price would otherwise be. On or after the date the Company gives such Share
Limitation Notice, upon notice from the Buyer, the Company promptly shall call a
special meeting of its shareholders, to be held not later than 60 days after
such notice is given, to seek the Shareholder Approval for the issuance of all
shares of Common Stock issuable in accordance with this Agreement without regard
to the Rule and shall use its best efforts to obtain the Shareholder Approval.
The Company shall prepare and file with the SEC within 20 days after such notice
is given preliminary proxy materials which set forth a proposal to seek such
Shareholder Approval. The Company shall provide the Buyer an opportunity to
consult with the Company regarding the content of such proxy materials insofar
as it relates to the Shareholder Approval by providing copies of such
preliminary proxy materials and any revised preliminary proxy materials to the
Buyer a reasonable period of time prior to their filing with the SEC. The
Company shall furnish to the Buyer a copy of its definitive proxy materials for
such special meeting and any amendments or supplements thereto promptly after
the same are mailed to shareholders or filed with the SEC. Upon the earlier of
(i) the failure to obtain Shareholder



                                       3
<PAGE>   4
Approval in accordance with Section 7(f), (ii) the failure to obtain the
Shareholder Approval at the special meeting provided in this paragraph or (ii)
the failure to hold such special meeting within such 60-day period provided in
this paragraph, the Company shall so notify the Buyer and such of the following
as shall be specified by notice to the Company from the Buyer shall occur: (1)
on the next Adjustment Date to occur the Adjustment Price shall be reduced to
70% of the amount such Adjustment Price would otherwise be and (2) the Company
shall promptly file applications and take all other actions necessary to (i)
list the Common Stock for trading and quotation on the OTC Bulletin Board or
such other securities market or exchange which will not restrict the number of
shares of Common Stock issuable under this Agreement and (ii) upon filing such
applications, request the immediate removal of the Common Stock from listing on
the securities market on which it is then listed which restricts the issuance of
shares of Common Stock under this Agreement without the Shareholder Approval.
Upon obtaining such Shareholder Approval or listing, as the case may be, the
Company shall promptly issue all Adjustment Shares and Repurchase Shares due
through the date of such issuance.

        For purposes of this Section 7, the term "Share Limitation Event" means
a time at which the Company is unable to issue all Adjustment Shares or
Repurchase Shares otherwise required to be issued by this Agreement by reason of
the restrictions set forth in the Rule and the Company has not obtained a waiver
thereof.

3. Each of the respective Registration Rights Agreements is hereby amended as
follows:

        (a) The definition of "Registrable Securities" in Section 1 thereof is
amended to read in its entirety as follows: "Registrable Securities" means the
Common Shares, the Warrant Shares and the Repurchase Shares."

        (b) Clause (i) of Section 2(a) is hereby amended to change the term
"150%" to "170%."

        (c) The third sentence of Section 2(a) is hereby amended to insert the
words "and Repurchase Shares" after each of the two references to "Adjustment
Shares" in such sentence.

4. This Agreement is binding upon each Buyer, any holder which acquires the
Common Shares from the Buyers (other than by transfers consummated pursuant to
the Registration Statement and Prospectus or pursuant to Rule 144 or another
exemption from registration under the 1933 Act), and any and all successors and
assigns of the Buyers. The Buyers hereby agree to deliver this document to all
assignees of the Subscription Agreement, the Registration Rights Agreements and
of the Common Shares (other than 



                                       4
<PAGE>   5

pursuant to transfers consummated pursuant to the Registration Statement and
Prospectus, or pursuant to Rule 144 or another exemption from registration under
the 1933 Act).

5. The recitals made above are an integral part of this Agreement and are hereby
incorporated herein and made a part hereof as though set forth in full in this
Section.

6. This Agreement is effective as of September 30, 1998.

7. All defined terms not defined herein are used as defined in the Subscription
Agreement.

8. The Company shall pay each Buyer's reasonable expenses, including attorney's

solely upon the use or sale of Products; provided such indemnification shall be
limited to the Unisys Assembly processes covering heat spreader attach, die
attach, wirebonding, encapsulation and marking. Unisys agrees to defend or

End Users. In any event, Tera at its own expense, shall have the right to
participate in the defense of any such action through Tera's own counsel. If any
Unisys assembly process as defined above is held to be an infringement or
misappropriation for which Tera is indemnified by Unisys, and its use is
enjoined, Unisys shall:

        a) procure for Tera and its customers the right to utilize the Product
granted herein, or

        b) replace or modify it so it becomes non-infringing (without
compromising Tera's intended use of said Products), or

        c) if neither of the foregoing is feasible, remove said Goods and refund
the purchase price and the transportation and installation cost thereof less
depreciation.

Unisys will not be liable if the infringing item has been modified by any of the
parties indemnified hereunder and such modification is the cause of any such
infringement or misappropriation, or if the infringement is due to the
combination of the Product with product not sold or licensed by Unisys
hereunder.


9.2     BUYER INDEMNITY

Tera agrees to indemnify and hold harmless Unisys and its subsidiaries from any
liability, damage or expense including but not limited to legal expenses,

its subsidiaries or third parties in connection with the promotion, sale or
licensing of Product to end users or a claim of any end user made directly
against Unisys or its subsidiaries based on promotion, sale or licensing of the
Product to end users by Tera, its subsidiaries or third parties. Tera agrees to
defend or settle, at Tera's expense, all suits or proceedings arising out of any
of the foregoing; provided that Unisys shall give Tera prompt written notice of
all suits or threats of suit against Unisys and its Subsidiaries. In any event,
Unisys, at its own expense, shall have the right to participate in the defense
of any such action through its own counsel.

the claim indemnified against is not a result of any violation by Unisys of its
obligations under this Agreement, or is not a result of any act of negligence of
Unisys.

Unisys warrants to Tera that for a period of twelve (12) months after shipment
to Tera the Product shall: (a) conform in all respects to all of the
requirements and Specifications in this Agreement; and (b) be free from all

the manner of storage, handling, next level assembly and rework are beyond
control of Unisys, this warranty is limited to defects that can be proven to be
present at the time of shipment or delivery of the Products to the carrier.

9.4     WARRANTY EXCLUSIONS

Unisys shall have no obligation under this Section 9 to repair or replace
Products when the defects result from accident, disaster, neglect, abuse,
misuse, transportation, alteration, improper storage, or improperly performed
repairs or activities once Product has been consigned to carrier and is out of
the control of Unisys.

Warranties granted hereunder are given to and enforceable only by Tera. No
warranties shall be assignable or transferable to subsequent purchasers or
lessors.

party may, upon not less than sixty (60) calendar days' prior written notice to
the party in breach, terminate this Agreement unless the breach is cured prior
to the end of the notice period. If a material breach is not cured within sixty

remedies as follows. Neither party shall exercise these rights without having
first attempted to resolve any dispute in accordance with the provisions of the

           Products scheduled for shipment at the time of Tera's default; (2)
           discontinue all work-in-process unless Tera requests completion and
           delivery and provides assurances of payment therefor acceptable to
           Unisys; (3) recover from Tera all costs incurred by Unisys for raw
           materials and labor for unfinished Products ordered by Tera, to the
           extent that Unisys is unable to return such raw materials for credit,
           or apply such raw materials and labor to the completion of Products
           for purchase by Tera or other Unisys customers; (4) recover from Tera
           all amounts due, but unpaid, for Products previously shipped to Tera
           and, (5) pursue any and all other remedies at law to which Unisys may
           be entitled.

Should any provision of this Agreement be finally determined to contravene any
applicable law or governmental regulation, such provision shall be automatically
terminated and performance thereof by both parties shall be waived to the extent
of such contravention. Should such provision be considered by either party to be
an essential element of this Agreement, the parties hereto agree to negotiate a
new, applicable provision in good faith.

13.2    TERMINATION

shall be in an amount consistent with prices specified herein.

In the event of the commencement of a case against Unisys under the U.S.
bankruptcy laws, whether voluntary or involuntary, Tera may elect to retain its
rights under this Agreement pursuant to 11 U.S.C. # 365(n). In this regard, the
designs, Manufacturing Processes, drawings libraries, and technical data
licensed to Tera under Section 12.1(c) shall be deemed to be "intellectual

If resolution is not achieved by negotiators at any given management level at
the end of their allotted time, then the allotted time for the negotiators at
the next management level, if any, will begin immediately. If resolution is not
achieved by negotiators at the final level within the allotted time, the parties
agree within forty-five (45) calendar days to select a form of alternative
dispute resolution (ADR) from informal non binding arbitration, private judging,
mini-trial, summary jury trial, moderated settlement conference, mediation or
other, and negotiate and ADR agreement for an ADR process. The ADR agreement
shall at least include provisions governing the ADR procedure, rules, discovery,
timing and cost allocations. In no event will such ADR process result in the
imposition of any element of punitive damages in the event of any awards.

If the ADR agreement is not agreed to by the parties within the time as set
forth in this Section 14.11 hereof, then either party may bring suit to resolve
the dispute in a court of competent jurisdiction. In the event of any material
breach between the parties hereto relating to this Agreement or the breach of
this Agreement, the prevailing party in any resulting litigation shall be
entitled to recover from the other party thereto the costs and expenses,
including reasonable attorneys fees, incurred in taking or defending such
action, including on any appeal.


14.12   AGENCY PRODUCT SUBMISSIONS

If Tera seeks regulatory or safety agency approval for Product, Unisys shall
cooperate and fully support Tera. Such cooperation primarily shall consist of
providing design and test data to support the submission.

product manufactured by Unisys or Tera, Unisys shall use its best efforts to
give notice thereof to Tera within 24 hours of receipt of such contact.


14.15   NON WAIVER

These terms and conditions set forth the entire understanding between the
parties with reference to the subject matter hereof. The failure of either party
to enforce at any time any of the provision hereof shall not constitute a waiver
