Item 2. Acquisition of Assets

           On July 28, 1998, Data Dimensions, Inc. (the "Company") entered into
a definitive agreement with ST Labs, Inc. ("ST Labs") and certain of its
shareholders, pursuant to which, on August 6, 1998, the Company acquired all of
the outstanding common stock of ST Labs in exchange for 515,300 shares of 
Company common stock. In addition, the Company assumed all options outstanding
under ST Labs' Option Plans. If fully excercised, such options will result in 
the issuance of approximately 158,000 additional shares of the Company's common
stock. The value of the Company shares exchanged in the Merger, combined with 
the shares issuable under the Option Plans, is approximately $9.7 million. ST 
Labs provides information technology services to its customers including 
recruiting contract test engineers, test automation training, and software 
testing in its own or customer locations, and testing facilities management. 
As a result of the transaction, ST Labs became a wholly-owned subsidiary of 
the Company. The Company intends to continue to use the assets acquired in the 
manner used by ST Labs prior to the acquisition.

Item 7. Financial statements and exhibits

(a)     Financial statements of business acquired

                Included herewith are ST Labs audited financial statements as of
        December 31, 1997 and for the year then ended and the unaudited
        financial statements as of March 31, 1998 and for each of the three
        month periods ended March 31, 1997 and 1998.

(b)     Pro forma financial information

                Included herewith is a pro forma condensed consolidated balance
        sheet as of March 31,1998, presented on the basis as if the Company's
        acquisition of ST Labs had occurred on March 31, 1998, and condensed
        consolidated statements of operations for each of the years ended
        December 31, 1995, 1996 and 1997 and each of the three month periods
        ended March 31, 1997 and 1998, presenting results of operations as the
        combined results of the Company and ST Labs.

                This business combination will be accounted for as a
        "pooling-of-interests" for financial reporting purposes. The
        pooling-of-interests method of accounting is intended to present as a
        single interest two or more common shareholder interests which were
        previously independent. Consequently, the historical financial
        statements for periods prior to the consummation of the combination will
        be restated as though the companies had been combined for all periods
        presented.

(c) Exhibits - The following exhibits are filed as a part of this report:

                        July 28, 1998.

                        [The following exhibits and schedules to the Agreement 
                        and Plan of Reorganization have been omitted:]

                       Report of Independent Accountants



To the Board of Directors
and Shareholders of
ST Labs, Inc.

In our opinion, the accompanying balance sheet and the related statements of
operations, of changes in shareholders' equity and of cash flow present fairly,
in all material respects, the financial position of ST Labs, Inc. at December
31, 1997 and the results of its operations and its cash flows for the year, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit on these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 8 to the
accompanying financial statements, the Company has incurred recurring losses
from operations and has a net capital deficiency and a net working capital
deficiency that raise substantial doubt about its ability to continue as a going
concern. The Company has signed a letter of intent to merge with another
corporation. This merger transaction and management's plans in regard to these
matters are also described in Note 8 to the accompanying financial statements.
The financial statements do not include any adjustments that might result from
the outcome of this uncertainty.

                          NOTES TO FINANCIAL STATEMENTS

NOTE 1 - DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of business - ST Labs, Inc. (the "Company"), formerly Software
Testing Laboratories, Inc., was incorporated in July 1993, in the State of
Washington. The Company provides services which include recruiting contract test
engineers, test automation training, software testing in Company facilities and
at customer locations, and managing a testing facility on behalf of one
particular customer.

Fair value disclosures - Recorded amounts of cash, accounts receivable, prepaid
and other current assets, accounts payable, and other amounts included in
current liabilities meeting the definition of financial instruments approximate
fair value.

Revenue recognition - Revenues are recognized in the period in which they are
earned, when services are provided.

Concentration of credit risk and significant customers - Financial instruments
that potentially subject the Company to concentration of credit risk include
primarily accounts receivable. Accounts receivable consists of account balances
due from several relatively large companies dispersed primarily across the
northwestern United States with industry concentration in information
technology. The Company performs ongoing credit evaluations of its customer's
financial condition and generally requires no collateral from its own customers.
Revenues from major customers exceeding 10% of total revenue included three
customers in 1997 accounting for 20%, 14%, and 11%, respectively, of total
revenue. These customers represented 12%, 14%, and 5% of accounts receivable at
December 31, 1997.

Equipment and furniture - Equipment and furniture are stated at cost and are
depreciated using the straight-line method over estimated useful lives of three
to five years. Leasehold improvements are amortized over the lesser of the lease
term or estimated useful life.

Income taxes - Income taxes are accounted for utilizing the liability method.
Deferred income taxes are provided to represent the tax consequences on future
years for temporary differences between tax and financial reporting basis of
assets and liabilities. A valuation allowance has been provided for the total
amount of deferred tax assets which would otherwise be recorded for income tax
benefits, primarily relating to operating loss carryforwards, as realization is
not considered more likely than not.

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

Stock-Based Compensation - Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("FAS 123"), encourages, but does not
require companies to record compensation cost for stock-based employee
compensation. The Company has chosen to continue to account for stock-based
compensation utilizing the intrinsic value method prescribed in Accounting
Principles Board Opinion No. 25 "Accounting for Stock Issued to Employees."
Accordingly, compensation cost for stock options is measured as the excess, if
any, of the fair market price of the Company's stock at the date of grant over
the amount an employee must pay to acquire the stock. Pro forma net loss is
presented on the basis as if the compensation has been determined pursuant to
FAS 123.

         (CONTINUED)

Interim Financial Statements - The interim financial data at March 31, 1998 and
for the three months ended March 31, 1997 and 1998 is unaudited; however, in the
opinion of the Company management, the interim data includes all adjustments,
consisting only of normal recurring adjustments necessary for a fair statement
of results for the interim periods. The interim results of operations for the
three months ended March 31, 1998 are not necessarily indicative of results
expected for the entire year.

NOTE 3 - RELATED PARTY TRANSACTIONS

The Company provides temporary employee placement services, testing facility
management, and software testing courses on a subcontract basis to a company
which is a shareholder of approximately 15% of the Company's common stock (a
"Significant Shareholder"). Revenues for these services amounted to
approximately $1.1 million in 1997, and related accounts receivable at December
31, 1997 approximated $76,000. In addition, the Significant Shareholder provides
temporary labor services to the Company, which during 1997 amounted to
approximately $1 million, and related accounts payable approximated $141,000 at
December 31, 1997.

 In April 1996, the Company borrowed $115,000 from related parties under terms
of loan and warrant purchase agreements. The notes bear interest at 18% per
annum payable monthly and are due in April 1998. The loans are unsecured and are
subordinated to notes payable to bank and are outstanding at June 30, 1998. The
loan agreements provide the holders with warrants to purchase 23,000 shares of
the Company's common stock for $.45 per share through April 1999.

In May 1997, the Company borrowed $100,000 from a related party under terms of a
loan and warrant purchase agreement. The note bears interest at 15% per annum
payable monthly, and is due in May 1998. The loan is unsecured and subordinated
to notes payable to bank and is outstanding at June 30, 1998. The agreement
provides the holder with warrants to purchase 2,000 shares of the Company's
common stock for $1.00 per share through January 2001.

In October 1997, the Company loaned $42,000 to certain shareholders bearing
interest at 12% per annum. The notes mature in October 1998 and may be extended
one year at the option of the holders.

NOTE 4 - REVOLVING LINE OF CREDIT AND NOTES PAYABLE

The Company has a revolving line of credit with commercial bank (the "Bank").
Amounts available under the line of credit are limited to a borrowing ceiling
calculated as a percentage of eligible accounts receivable and to a maximum
borrowing outstanding of $1.5 million. The line of credit bears interest at
prime plus 1% (9.50% at December 31, 1997). This agreement contains certain
restrictive covenants with which the Company was not in compliance at December
31, 1997. The Company has not received a waiver of these covenant violations
from the Bank. However, in April 1998, the Company's revolving line of credit
agreement was amended to, among other things, increase the maximum available
borrowing to $2 million and revise certain restrictive covenants. Subsequently,
the Company became in violation of the revised restrictive covenants and such
non-compliance continues through July 13, 1998.

In February 1997, the Company entered into a term loan agreement with the Bank
providing for maximum borrowings of $2 million over an 18 month period. The
Company borrowed $1 million with the remainder becoming available to borrow,
subject to certain performance targets. Amounts outstanding under the agreement
bear interest at 12% per annum. In connection with this loan, the Company issued
to the Bank a warrant to purchase 10% of the Company's common stock under
certain future conditions, including if the loan is not paid in full upon
maturity. The Company is obligated under certain circumstances to pay $75,000 if
repayment occurs prior to August 28, 1998 and $150,000 thereafter.

At December 31, 1997, the Company has three equipment notes payable to the Bank
which bear interest between 10% and 11% annually and are due in monthly
installments through February 2002.

The revolving line of credit, term loan and equipment loans are secured by
substantially all assets of the Company and are guaranteed by the Company's two
principal shareholders. Interest paid on Bank borrowings was $407,000 during
1997. Notes payable consist of the following (in thousands):

NOTE 5 - INCOME TAXES

Deferred income taxes recorded for significant temporary differences between tax
and financial reporting basis of assets and liabilities approximate $910,000 at
December 31, 1997 and primarily relate to operating loss carryforwards. A
valuation allowance has been recorded for the full amount of deferred taxes as
realization of such deferred tax asset is not considered to be more likely than
not. The change in the valuation allowance approximated $850,000 in 1997.

Deferred tax assets at December 31, 1997 are summarized as follows (in
thousands):

</TABLE>

For income tax purposes, at December 31, 1997, the Company had net operating
loss carry-forwards of approximately $1.7 million which expire in 2008 through
2012. As a result of changes in ownership, utilization of net operating loss
carryforwards are subject to annual limitations.

NOTE 6 - COMMON STOCK AND STOCK OPTIONS

In February 1997, the Company amended its Articles of Incorporation to authorize
the issuance of 25 million shares of common stock and the Board of Directors
declared a ten-for-one stock split on the Company's common stock effected in the
form of stock dividend to holders of record on that date. All share information
has been restated to reflect this split.

During 1997, the Company extended the exercise period for stock options granted
to certain terminated employees and recorded compensation expense of $329,000.

During 1997, certain shareholders of the Company made a capital contribution of
approximately $67,000 to enable the Company to pay an employee severance
obligation.

The Company adopted a Stock Option Plan (the 1995 Plan) in 1995 for key
employees, under which 2 million shares of common stock are reserved for stock
option grants. The vesting period, exercise price and expiration period of
options are established at the discretion of the Board of Directors, except that
incentive stock options must be granted with exercise prices of not less than
100% of fair market value of the underlying common stock on the date of grant.
Options issued under the 1995 Plan become fully vested upon the completion of a
change in control transaction. In 1997, the Company established a 1997 Stock
Option Plan (the 1997 Plan) for key employees under which 500,000 shares of
common stock are reserved for stock option grants. Most terms are comparable to
the 1995 Plan. Stock options vest and become exercisable over periods of one to
three years and expire ten years from the date of grant. Outstanding stock
options at December 31, 1997 had a weighted average contractual life of 8.1
years.

The per share weighted average fair value of stock options granted during 1997
was $0.27 on the date of grant using the minimum value method with the following
weighted average assumptions: expected dividend yield of zero; risk-free
interest rate of 6.6% and an expected life of 5 years.

NOTE 6 - COMMON STOCK AND STOCK OPTIONS (CONTINUED)

The Company applies APB Opinion No. 25 in accounting for employee stock options
and, accordingly, compensation cost has been recognized in the financial
statements only to the extent that the option exercise price is less than the
fair value of the underlying stock on the measurement date. Had the Company
determined compensation cost based on fair value at the grant date for its stock
options under SFAS No. 123, the Company's net loss would have been increased
from $2.89 million to a pro forma loss of $2.93 million. The full impact of
compensation cost for stock options under SFAS No. 123 is not reflected in the
pro forma net loss amount because compensation cost is amortized over the
options' vesting period of three years.

The following summarizes stock option activity:

The Company leases its corporate headquarters in Bellevue, Washington, under
terms of a noncancelable operating lease that expires in August 2003, subject to
extensions at the Company's option. The Company is responsible for its share of
any property tax and operating costs higher than forecasted for this location.
The Company also has two other noncancelable testing facilities leases expiring
in 2002. The Company has subleased one of these sites to a third party through
March 1999. The Company also leases computer equipment under two operating
leases expiring in 1999 and 2000. Rent expense under noncancelable operating
leases approximated $1.36 million in 1997.

NOTE 8 - LIQUIDITY

The accompanying financial statements have been prepared assuming the Company
will continue as a going concern. To date, the Company incurred recurring
operating losses and has a net capital deficiency and a working capital deficit.
Additionally, as disclosed in Note 4, the Company is in violation of its debt
covenants and substantially all of its outstanding Bank debt is due by the end
of 1998. Based on the Company's current projected earnings and cash flow,
Company management does not believe that cash generated from operations alone
will be sufficient to pay its debt by December 31, 1998. Management is
considering financing alternatives which include, among other things, a business
combination, sale of assets, or a refinancing of the bank debt.

In June 1998 the Company signed a letter of intent to combine with another
corporation. The merger is a stock for stock combination and is intended to be
accounted for as a pooling of interests transaction.

If the above transaction or other financing alternative does not occur, and the
Company is unable to make required payments due December 31, 1998, it may be
unable to continue its operations, except to the extent permitted by the Bank.

The accompanying pro forma financial information gives effect to the business
combination of Data Dimensions, Inc. (the "Company") and ST Labs, Inc. ("ST
Labs"). This business combination will be accounted for as a
"pooling-of-interests" for accounting and financial reporting purposes. The
pooling-of-interests method of accounting is intended to present as a single
interest two or more common shareholder interests which were previously
independent. Consequently, the historical financial statements for periods prior
to the consummation of the combination will be restated as though the companies
had been combined for all periods presented.

The pro forma financial statements included herein should be read in conjunction
with the Company's audited, annual financial statements included in the
Company's December 31, 1997 Annual Report on Form 10-KSB and its unaudited
interim financial statements included in the Company's March 31, 1998 Quarterly
Report on Form 10-Q, and the ST Labs financial statements, which are included in
this Form 8-K.

The accompanying pro forma condensed consolidated balance sheet presents the
financial position of the combined businesses as of March 31, 1998, giving
effect to the business combination utilizing the pooling-of-interests method of
accounting.

The accompanying pro forma condensed consolidated statements of operations for
each of the years ended December 31, 1995, 1996 and 1997 and each of the three

         NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1998


(a)     All fees and expenses related to the business combination and to the
        consolidation of the combining companies will be expensed as required
        under the pooling-of-interest accounting method. These expenses have not
        been reflected in the unaudited pro forma condensed consolidated balance
        sheet or statements of operations, but will be reflected in the
        statement of operations of the Company in the period the business
        combination is consummated. Such fees and expenses are presently
        estimated to approximate $750,000.

(b)     The calculation of unaudited pro forma net income per common share for
        each period presented reflects the issuance of Company common stock in
        exchange for all of the outstanding shares of ST Labs common stock. The
        number of shares included in the basic earnings per share computation
        has been determined utilizing the exchange ratio of Company shares for
        ST Labs shares as set forth in the business combination merger agreement
        (the "Exchange Ratio") based upon the actual weighted average number of
        ST Labs common shares outstanding during the period presented, and a per
        share price of Company common stock of $14.38. The computation of
        diluted earnings per share is similar to the computation of basic
        earnings per share, except that the number of shares utilized as the
        denominator is increased to include the number of ST Labs additional
        shares that would have been outstanding if dilutive common shares had
        been issued. Outstanding options and warrants have been considered
        utilizing the Treasury stock method in calculating dilutive earnings per
        share.

                      AGREEMENT AND PLAN OF REORGANIZATION


        THIS AGREEMENT AND PLAN OF REORGANIZATION (the agreement, schedules, and
exhibits are hereinafter referred to as this "Agreement") is made and entered
into as of July 28, 1998 (the "Effective Date") among Data Dimensions, Inc., a
Delaware corporation ("Parent"), DS Acquisition Corporation, a Washington
corporation and a wholly-owned subsidiary of Parent ("Merger Sub"), ST Labs,
Inc., a Washington corporation (the "Company"), and Robert Arnold, Jr. and Tye
V. Minckler (individually, a "Principal Shareholder," and collectively the
"Principal Shareholders").

        WHEREAS, the Boards of Directors of each of the Company, Parent and
Merger Sub believe it is in the best interests of each company and their
respective stockholders that Parent acquire the Company through the statutory
merger of Merger Sub with and into the Company (the "Merger") and, in
furtherance thereof, have approved the Merger;

        WHEREAS, pursuant to the Merger, among other things, and subject to the
terms and conditions of this Agreement, all of the issued and outstanding shares
of common stock, no par value, of the Company ("Company Common Stock") will be
converted into Common Stock of Parent ("Parent Common Stock");

        WHEREAS, a portion of the shares of Parent Common Stock issuable by
Parent in connection with the Merger will be placed in escrow by Parent, the
release of which amount will be contingent upon certain events and conditions,
all as set forth in Section 1.8.2 hereof; and

        WHEREAS, the Company, Principal Shareholders, Parent and Merger Sub
desire to make certain representations and warranties and other agreements in
connection with the Merger.

         NOW, THEREFORE, in consideration of the covenants, promises and
  representations set forth herein, and for other good and valuable
  consideration, intending to be legally bound hereby, the parties agree as
  follows:

                             ARTICLE I - THE MERGER

Section 1.1 The Merger.

           At the Effective Time (as defined in Section 1.3) and subject to and
  upon the terms and conditions of this Agreement and applicable law, including
  without limitation, the Washington Business Corporation Act ("WBCA"), Merger
  Sub will be merged with and into the Company, the separate corporate existence
  of Merger Sub will cease and the Company will continue as the surviving
  corporation and as a wholly-owned subsidiary of Parent. The Company as the
  surviving corporation after the Merger is hereinafter sometimes referred to
  as the "Surviving Corporation."



                                       1
<PAGE>   6

Section 1.2 Written Consent of the Shareholders of the Company.

        The Company will take all action necessary or advisable in accordance
with applicable law and Articles of Incorporation and Bylaws (i) to solicit the
approval of this Agreement, the Merger and all the transactions contemplated
hereby, by all holders of the issued and outstanding stock of the Company (the
"Company Shareholders"), by means of a unanimous written consent of shareholders
(the "Company's Shareholders' Consent"), or (ii) to call, give notice of,
convene and hold a special meeting of the shareholders of the Company to be held
for the purpose of voting upon this Agreement, the Merger and all the
transactions contemplated thereby. The Company shall use its best efforts to
obtain such shareholder approval. The Company represents and warrants that its
Board of Directors, at a meeting duly called and held, has (x) determined that
the Merger is fair to and in the best interests of the Company and the Company
Shareholders and (y) resolved to recommend to the Company Shareholders that they
approve this Agreement, the Merger and all the transactions contemplated hereby.

Section 1.3 Effective Time.

        Unless this Agreement is earlier terminated pursuant to Section 7.1,
the closing of the Merger (the "Closing") will take place following satisfaction
or waiver of the conditions set forth in Section 6, at the offices of Garvey,
Schubert & Barer in Seattle, Washington on August 6, 1998, unless another place
or time is agreed to by Parent and the Company. The date upon which the Closing
actually occurs is herein referred to as the "Closing Date." As soon as
practicable following the Closing, the parties hereto will cause the Merger to
be consummated by filing Articles of Merger substantially in the form of Exhibit
1.3 with the Secretary of State of the State of Washington (the "Articles of
Merger") in accordance with the WBCA (the time of acceptance of such filing
being referred to herein as the "Effective Time"). Each certificate which before
the Effective Time represented shares of Company Common Stock shall thereafter
evidence ownership of the number of full shares of Parent Common Stock into
which such shares of Company Common Stock shall have been so converted pursuant
to Section 1.7.1 hereof.

Section 1.4 Effect of the Merger.

        At the Effective Time, the effect of the Merger will be as provided by
the WBCA. Without limiting the generality of the foregoing, and subject thereto,
at the Effective Time, all the property, rights, privileges, powers and
franchises of the Company and Merger Sub will vest in the Surviving Corporation,
and all debts, liabilities and duties of the Company and Merger Sub will become
the debts, liabilities and duties of the Surviving Corporation.

Section 1.5 Certificate of Incorporation; Bylaws.

        Unless otherwise determined by Parent prior to the Effective Time, at
the Effective Time, the Articles of Incorporation and Bylaws of the Merger Sub
as in effect immediately prior to the Effective Time will be the Articles of
Incorporation and Bylaws of the Surviving Corporation until thereafter amended.



                                       2
<PAGE>   7

Section 1.6 Directors and Officers.

        From and after the Effective Time: (a) the director(s) of Merger Sub
immediately prior to the Effective Time will be the director(s) of the
Surviving Corporation, each to hold office in accordance with the Articles of
Incorporation and Bylaws of the Surviving Corporation; and (b) the officers of
Merger Sub immediately prior to the Effective Time will be the officers of the
Surviving Corporation, each to hold office in accordance with the Bylaws of the
Surviving Corporation.

Section 1.7 Conversion of Common Stock.

        1.7.1 Exchange Ratio.

        Each share of Company Common Stock issued and outstanding immediately
before the Effective Time will, at the Effective Time, by virtue of the Merger
and without any action on the part of the holder thereof, be converted into the
right to receive that fraction of a share of Parent Common Stock equal to the
quotient (the "Exchange Ratio") obtained by dividing

        (i) the amount obtained by dividing (a) Nine Million Six Hundred Seventy
        Five Thousand Dollars ($9,675,000) by (b) the Parent Average Closing
        Price, by

        (ii) the number of Fully Diluted Company Shares at the Effective Time.

For purposes of this Agreement, "Parent Average Closing Price" shall mean the
average of the closing prices of Parent Common Stock as reported for
consolidated trading on the NASDAQ National Market System, as reported in the
Wall Street Journal beginning on and including the Effective Date and ending on
and including the date that is two (2) trading days prior to the Closing Date,
provided that (i) if such average is less than $14.00, the "Parent Average
Closing Price" shall be $14.00, and (ii) if such average is more than $16.00,
the "Parent Average Closing Price" shall be $16.00. For purposes of this
Agreement, "Fully Diluted Company Shares" shall mean the sum of (i) the number
of shares of Company Common Stock outstanding as of the Effective Time plus (ii)
the number of shares of Company Common Stock subject to issuance pursuant to
stock options outstanding under the Company Stock Option Plans (as defined in
Section 1.7.1 below), plus (iii) 58,690 shares of Company Common Stock which
will be converted into Exchange Shares in exchange for the warrant held by U.S.
Bank in accordance with Exhibit 6.3.13. The shares of Parent Common Stock issued
at the Effective Time pursuant to this Section 1.7.1 to holders of Company
Common Stock and pursuant to Exhibit 6.3.13 are hereinafter referred to as the
"Exchange Shares". As soon as practicable after the Effective Time, the Company
Shareholders will surrender all certificates representing Company Common Stock
to Parent or a designated exchange agent, together with such duly executed
documentation as may be required by Parent or the exchange agent to effect a
transfer of such shares.

        1.7.2 Company Stock Option Plans.

        At the Effective Time, the Software Testing Laboratories, Inc. 1995
Stock Option Plan (the "1995 Plan") and the ST Labs, Inc. 1997 Stock Option Plan
(the "1997 Plan," and together



                                       3
<PAGE>   8

with the 1995 Plan, the "Company Stock Option Plans") shall be assumed by Parent
in accordance with Section 5.11 hereof.

        1.7.3 Capital Stock of Merger Sub.

        Each share of Common Stock of Merger Sub issued and outstanding
immediately prior to the Effective Time will by virtue of the Merger and without
any action on the part of the holder thereof, be converted into and exchanged
for one validly issued, fully paid and nonassessable share of Common Stock of
the Surviving Corporation. The Surviving Corporation will issue a stock
certificate evidencing ownership of any such shares of capital stock of the
Surviving Corporation upon surrender of the certificates that formerly
represented the Common Stock of Merger Sub.

        1.7.4 Adjustments.

        The Exchange Ratio herein will be adjusted to reflect fully the effect
of any stock split, reverse split, stock dividend (including any dividend or
distribution of securities convertible into Parent Common Stock or Company
Common Stock), reorganization, recapitalization or other like change with
respect to Parent Common Stock or Company Common Stock occurring after the date
hereof and prior to the Effective Time.

        1.7.5 Fractional Shares.

        No fractional shares of Parent Common Stock will be issued in the
Merger. In lieu of any fractional share of Parent Common Stock to which a holder
would have otherwise been entitled, Parent shall pay in cash an amount equal to
the product of such fractional share multiplied by the Average Parent Closing
Price.

        1.7.6 Limitation on Shares Issuable.

        In no event shall the aggregate value of Parent Common Stock which
Parent is obligated to issue (i) upon the assumption of the Company Stock Option
Plans and (ii) in exchange for outstanding shares of Company Common Stock
pursuant to this Agreement exceed Nine Million Six Hundred Seventy Five Thousand
Dollars ($9,675,000) calculated on the basis of the Parent Average Closing
Price.

        1.7.7 Private Placement.

        The Parent Common Stock to be issued in the Merger is intended to be
exempt from the registration requirements of the Securities Act of 1933 (the
"Securities Act") pursuant to the private placement exemption provided by
Section 4(2) of the Securities Act and applicable state securities laws. Each
Principal Shareholder hereby agrees to take all reasonable actions and execute
all documents necessary or advisable to qualify the issuance of the Parent
Common Stock pursuant to this Agreement for such exemptions.



                                       4
<PAGE>   9

Section 1.8 Surrender of Certificates.

        1.8.1 Parent to Provide Common Stock and Cash.

        Promptly after the Effective Time, Parent shall, in accordance with this
Section 1.8, (i) issue certificates representing the aggregate number of
Exchange Shares of Parent Common Stock issuable pursuant to Section 1.7.1 in
exchange for certificates formerly representing outstanding shares of Company
Common Stock, and (ii) tender cash in an amount sufficient to permit payment of
cash in lieu of fractional shares pursuant to Section 1.7.4 (the Exchange Shares
and such cash are collectively referred to as the "Merger Consideration").

        1.8.2 Exchange Procedures.

        At the Closing, each holder of record of a certificate or certificates
which immediately prior to the Effective Time represented issued and outstanding
Company Common Stock (individually a "Certificate" and collectively the
"Certificates") shall deliver to the Parent such shareholder's Certificates. The
holder of such Certificate(s) shall be entitled to receive at the Effective Time
in exchange therefor a certificate representing all of the Exchange Shares
(excluding those shares being placed in escrow as described below) and all the
cash, if any, that such holder is entitled to receive pursuant to Section 1.7
hereof. Of the Exchange Shares otherwise issuable to the Company Shareholders
under Section 1.7.1, a number of Exchange Shares equal to 10% of the aggregate
thereof (the "Indemnification Escrow Shares") rounded up to the nearest whole
share shall be deposited by the Parent with ChaseMellon Shareholder Services,
Inc. ("ChaseMellon" or the "Escrow Agent") in accordance with the terms and
conditions of the Escrow Agreement substantially in the form of Exhibit 1.8.2
(the "Indemnification and Escrow Agreement"). The number of Indemnification
Escrow Shares to be delivered on behalf of each Company Shareholder shall equal
the product of (i) the total number of Indemnification Escrow Shares to be
delivered to the Escrow Agent and (ii) a fraction, the numerator of which is the
number of shares of Parent Common Stock to be received by such Company
Shareholders as Merger Consideration and the denominator of which is the total
number of Exchange Shares, rounded up to the next whole share. The delivery of
the Indemnification Escrow Shares shall be made on behalf of the Company
Shareholders in accordance with the provisions hereof, with the same force and
effect as if such shares had been delivered by Parent directly to such holders
and subsequently delivered by such holders to the Escrow Agent. The shares so
deposited shall be evidenced by a stock certificate in the names of the Company
Shareholders and shall be subject to the restrictions on transfer and assignment
provided in the Indemnification and Escrow Agreement. The Indemnification Escrow
Shares shall not be eligible for registration pursuant to the Registration
Rights Agreements (defined in Section 5.1) of even date herewith. Tye V.
Minckler has been selected by the Company Shareholders as the initial
representative of the Company Shareholders (the "Indemnification
Representative") and, in the event of the inability or unwillingness prior to
the execution of the Indemnification and Escrow Agreement of Tye V. Minckler to
act as Indemnification Representative, a substitute Indemnification
Representative will be selected by the holders of a majority of the shares of
Parent Common Stock to be issued as Merger Consideration. Such Indemnification
Representative is authorized by this Agreement, as a specific term of the Merger
provided for herein, to act as Indemnification Representative of the Company
Shareholders in



                                       5
<PAGE>   10

accordance with the provisions hereof, with the powers and authority provided
for in the Indemnification and Escrow Agreement. The approval of this Agreement
by the Company Shareholders shall also constitute their approval of the terms
and provisions of the Indemnification and Escrow Agreement, their confirmation
of the appointment of ChaseMellon to act as Escrow Agent, and their approval of
the terms and provisions therein relating to the Indemnification Representative,
including the provisions relating to the appointment of replacements, and their
confirmation of the appointment of Tye V. Minckler to act as the initial
Indemnification Representative.

        1.8.3 Restricted Stock; Transfer Restrictions; Legends.

        The shares of Parent Common Stock issued in the Merger shall not be
transferable in the absence of an effective registration statement under the
Securities Act, or an exemption therefrom. In the absence of an effective
registration statement under the Securities Act, neither such shares of Parent
Common Stock nor any interest therein shall be sold, transferred, assigned or
otherwise disposed of, unless Parent shall have previously received an opinion
of counsel knowledgeable in federal securities law, in form and substance
reasonably satisfactory to Parent and accompanied by such supporting documents
as Parent may reasonably request, to the effect that registration under the
Securities Act is not required in connection with such disposition. Parent shall
be entitled to give stop transfer instructions to its transfer agent with
respect to such shares of Parent Common Stock in order to enforce the foregoing
restrictions.

        The certificate or certificates representing the shares of Parent Common
Stock issued in the Merger shall bear the following legend restricting the
transfer thereof, in addition to any other legend required by applicable law:

        "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT
TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE
COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED."

        1.8.4 No Further Ownership rights in Company Common Stock.

        All Exchange Shares and any cash paid in lieu of fractional Exchange
Shares shall be deemed to have been issued or paid, respectively, in full
satisfaction of all rights pertaining to such shares of Company Common Stock,
and there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Company Common Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time, Company
Common Stock certificates are presented to the Surviving Corporation for any
reason, they shall be cancelled and exchanged as provided in this Article 1.



                                       6
<PAGE>   11

Section 1.9   Dissenters' Rights.

        Notwithstanding anything to the contrary contained this Agreement, any
holder of Company Common Stock issued and outstanding immediately prior to the
Effective Time with respect to which dissenters' rights, if any, are granted by
reason of the Merger under the WBCA and who does not vote in favor of the Merger
and who otherwise complies with Chapter 23B.13 of the WBCA ("Dissenting Company
Shares") shall not be converted into the right to receive the Merger
Consideration at or after the Effective Time pursuant to Section 1.7, unless
such holder fails to perfect, effectively withdraws or loses his or her right to
dissent from the Merger under the WBCA. Such holder shall have only such rights
as are granted by Chapter 23B.13 of the WBCA. If a holder of Dissenting Company
Shares fails to perfect, withdraws or loses his or her dissenters' rights under
the WBCA, then, as of the Effective Time or the occurrence of such event of
failure, withdrawal or loss, whichever last occurs, such holder's Dissenting
Company Shares shall cease to be Dissenting Company Shares and shall be
converted into the right to receive, and shall be exchangeable for, the Merger
Consideration into which such Dissenting Company Shares would have been
otherwise converted pursuant to Section 1.7 hereof.

Section l.10 Tax and Accounting Consequences.

        It is intended by the parties hereto that the Merger will (i) constitute
a tax-free reorganization within the meaning of Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code") and (ii) be accounted for as a

(ii) a federal or state court shall have issued a final, nonappealable order
preventing consummation of the Merger; or (iii) any Governmental Entity shall
have enacted, promulgated or issued or deemed applicable to the Merger any
statute, rule, regulation or order that would make consummation of the Merger
illegal.

         7.1.3 By Parent if there will be any action taken, or any statute,
rule, regulation or order enacted, promulgated or issued or deemed applicable to
the Merger, by any Governmental Entity, which would: (i) prohibit Parent's or
the Company's ownership or operation of any portion of the business of the
Company or (ii) compel Parent or the Company to dispose of or hold separate, as
a result of the Merger, any portion of the business or assets of the Company or
Parent;

         7.1.4 By Parent if there has been a breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of the
Company or the Principal Shareholders and as a result of such breach the
conditions set forth in Section 6.3.1 or Section 6.3.2, as the case may be,
would not then be satisfied; and

         7.1.5 By the Company if there has been a breach of any representation,
warranty, covenant or agreement contained in this Agreement on the part of
Parent or Merger Sub and as a result of such breach the conditions set forth in
Section 6.2.1 or Section 6.2.2, as the case may be, would not then be satisfied.

         Where action is taken to terminate this Agreement pursuant to this
Section 7.1, it will be sufficient for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

Section 7.2 Effect of Termination.

         Each party's right of termination under Section 7.1 is in addition to
any other rights it may have under this Agreement or otherwise, and the exercise
of a right of termination will not be an election of remedies. If this Agreement
is terminated pursuant to Section 7.1, all further obligations of the parties
under this Agreement will terminate except the obligations in Section 5.3 will
survive; provided, however, if this Agreement is terminated by a party because
of breach of this Agreement by the other party or because one or more conditions
to the terminating party's obligations under this Agreement are not satisfied as
a result of the other party's failure to comply with its obligations under this
Agreement, the terminating party's right to pursue all legal remedies will
survive such termination unimpaired.

Section 7.3 Amendment.

         This Agreement may be amended by the parties hereto by action taken or
authorized by their respective Boards of Directors, at any time before or after
approval of the matters presented in connection with the Merger by the Company
Shareholders but after any such approval, no amendment may be made which by law
requires further approval by such shareholders without



                                       39
<PAGE>   44

such further approval. This Agreement may not be amended except by execution of
an instrument in writing signed on behalf of each of the parties hereto.

Section 7.4 Extension; Waiver.

         At any time prior to the Effective Time, Parent and Merger Sub, on the
one hand, and the Company, on the other, may, to the extent legally allowed, (i)
extend the time for the performance of any of the obligations of the other party
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto, and
(iii) waive compliance with any of the agreements or conditions for the benefit
of such party contained herein. Any agreement on the part of a party hereto to
any such extension or waiver will be valid only if set forth in an instrument in
writing signed on behalf of such party and shall not prejudice or otherwise
influence whatsoever any other agreements or conditions and/or require or imply
additional future waivers or extensions on similar or different matters.

        THIS STOCK RESTRICTION AND REGISTRATION RIGHTS AGREEMENT (this
"Agreement") is entered into as of August ___ , 1998, by and among Data 
Dimensions, Inc., a Delaware corporation (the "Company") and those shareholders 
and warrantholders of ST Labs, Inc., a Washington corporation ("STL"),
appearing as signatories hereto (each, a "Holder" or, as the context requires, 
"seller," and collectively, the "Holders").

        WHEREAS, pursuant to the Agreement and Plan of Reorganization dated as
of July 28 , 1998 (the "Merger Agreement"), by and among the Company, DS
Acquisition Corporation, a Washington corporation and wholly-owned subsidiary of
the Company ("Merger Sub"), STL, Robert Arnold, Jr., and Tye V. Minckler, Merger
Sub is being merged with and into STL (the "Merger"); and

        WHEREAS, in connection with the Merger Agreement, the shareholders of
STL and U.S. Bancorp (as warrantholder) are acquiring shares of Common Stock of
the Company pursuant to certain exemptions from the registration requirements of
the Securities Act (as defined below); and

        WHEREAS, the Company has agreed to grant to the Holders certain
registration rights.

        NOW, THEREFORE, in consideration of the foregoing premises and for other
good and valuable consideration, the parties hereby agree as follows:

        1. Certain Definitions. As used in this Agreement, the following terms
shall have the following respective meanings:

        "ASR 130 and 135" shall mean the Commission Accounting Series Release
Nos. 130 and 135, as amended.

        "Commission" shall mean the Securities and Exchange Commission or any
other federal agency at the time administering the Securities Act.

        "Common Shares" shall mean the shares of Common Stock of the Company

<PAGE>   2
        "Quarterly Report Filing Date" shall mean the date that the Commission
requires the Company to file a quarterly or annual report with respect to the
first three month fiscal quarter after the effective time of the Merger which

post-closing operations required by ASR 130 and 135.

        "Registration Expenses" shall mean the expenses so described in 
Section 8.

        "Restricted Stock" shall mean the Common Shares, excluding Common Shares

        2. Restrictions On Transfer.

         Each Holder agrees that such Holder will not transfer or
otherwise reduce such Holder's risks relative to the Common Shares to be
received by each Holder until such time as the Company notifies the Holder that
the requirements of ASR 130 and 135 have been met. Each Holder understands that
ASR 130 and 135 relate to publication of financial results of post-closing
combined operations of the Company and STL. The Company agrees that it will
publish such results on or before the Quarterly Report Filing Date, and that it
will notify the Holders promptly following such publication.

        3. Compliance with Securities Laws. Each Holder represents and warrants
that:

               (a) Holder has received and reviewed the Confidential Offering
Memorandum, which includes copies of the following:

                      (i) The Merger Agreement;

                      (ii) The Company's 1997 Annual Report to Shareholders;

fiscal year ended December 31, 1997;

                                       2


<PAGE>   3
                      (v) The Company's Proxy Statement for its 1998 Annual
Meeting of Stockholders.

               (b) Holder acknowledges that [CHECK AT LEAST ONE BOX]:

               [ ] Holder is an "accredited investor" as defined in Rule 501(a)
of Regulation D as adopted by the Commission, as set forth in Appendix 1 hereto.

               [ ] William L. Eisenhart has acted as Holder's purchaser
representative (as defined in Rule 501(h) of Regulation D as adopted by the
Commission) in connection with evaluating the merits and risks of the Merger.

               (c) Holder has been advised that, as of the date hereof, Holder
may be deemed to be an "affiliate" of STL, as the term "affiliate" is used in
and for purposes of ASR 130 and 135.

               (d) Holder understands that the representations, warranties and
covenants set forth herein will be relied upon by STL, other shareholders of
STL, the Company, shareholders of the Company and their respective counsel and
accounting firms.

               (e) Holder hereby represents and warrants that Holder has not
sold, exchanged, transferred, pledged, disposed of or otherwise reduced Holder's
risk relative to any shares of STL common stock owned by Holder during the
thirty (30) day period preceding the date hereof.

               (f) Holder is acquiring the Common Shares to be issued to Holder
solely in exchange for the shares of capital stock of STL owned by Holder or
otherwise issuable to Holder by STL in connection with the transactions
contemplated by the Merger Agreement.

               (g) Holder has paid no brokerage or similar commissions in
connection with the acquisition of such Common Shares.

               (h) Holder is acquiring such Common Shares solely for Holder's
account.


                                       3


<PAGE>   4
               (i) Holder has provided such information as may reasonably have
been requested by the Company in order for the Company or its counsel to
evaluate the availability of an exemption under the Securities Act for the
issuance of Company Stock to Holder.

        4. Securities Act Matters. Each Holder acknowledges and agrees that the
Common Shares to be issued to Holder have not been (and at the time of
acquisition by Holder, will not have been) registered under the Securities Act
or under the securities laws of any state, in reliance upon certain exemptive
provisions of such statutes. Holder recognizes and acknowledges that such claims
of exemption are based, in part, upon each Holder's representations contained in
this Agreement. Holder further recognizes and acknowledges that, because the
Common Shares are unregistered under federal and state laws, they are not
presently eligible for public resale, and may be sold in the future only
pursuant to an effective registration statement under the Securities Act and any
applicable state securities laws, or pursuant to a valid exemption from such
registration requirements. Holder recognizes and acknowledges that Rule 144
promulgated under the Securities Act (which facilitates routine sales of
securities in accordance with the terms and conditions of that Rule, including a
holding period requirement) is not now available to Holder for resale of the
Common Shares, and Holder recognizes and acknowledges that, in the absence of
the availability of Rule 144, a sale pursuant to a claim of exemption from
registration under the Securities Act would require compliance with some other
exemption under the Securities Act, none of which may be available for resale of
the Common Shares by Holder. Holder recognizes and acknowledges that, except as
set forth in this Agreement, the Company is under no obligation to register the
Common Shares, either pursuant to the Securities Act or the securities laws of
any state.

        5. Restrictive Legend. Each certificate representing Common Shares
shall, except as otherwise provided in this Section 5 or in Section 6, be
stamped or otherwise imprinted with a legend substantially in the following
form:


        "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
        AND MAY NOT BE TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS IT HAS BEEN
        REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS
        AVAILABLE.

        THE HOLDER OF THIS SECURITY IS ENTITLED TO CERTAIN REGISTRATION RIGHTS
        SET FORTH IN A STOCK RESTRICTION AND REGISTRATION RIGHTS AGREEMENT DATED
        AUGUST ______, 1998, A COPY OF WHICH MAY BE OBTAINED FROM THE SECRETARY
        OF THE CORPORATION."

Such certificates shall not bear such legend if in the opinion of counsel
satisfactory to the Company the securities being sold thereby may be publicly
sold without registration under the Securities Act or if such securities have
been sold pursuant to Rule 144 or an effective registration statement.


                                       4


<PAGE>   5
        6. Notice of Proposed Transfer. Prior to any proposed transfer of any
Common Shares, Holder shall give written notice to the Company of the Holder's
intention to effect such transfer. Each such notice shall describe the manner of
the proposed transfer and, if requested by the Company, shall be accompanied by
an opinion of counsel satisfactory to the Company to the effect that the
proposed transfer may be effected without registration under the Securities Act,
whereupon Holder shall be entitled to transfer such security in accordance with
the terms of its notice; provided, however, that no prior notice or opinion of
counsel shall be required if the sale is made in compliance with Rule 144 or if
such transfer is to one or more partners of the transferor (in the case of a
transferor that is a partnership). Each certificate for Common Shares
transferred as above provided shall bear the legend set forth in Section 5,
except that such certificate shall not bear such legend if (i) such transfer is
in accordance with the provisions of Rule 144 (or any other rule permitting
public sale without registration under the Securities Act) or (ii) the opinion
of counsel referred to above is to the further effect that the transferee and
any subsequent transferee (other than an affiliate of the Company) would be
entitled to transfer such securities in a public sale without registration under
the Securities Act. The restrictions provided for in this Section 6 shall not
apply to securities which are not required to bear the legend prescribed by
Section 5 in accordance with the provisions of that Section.

        7. Registration Procedures. On or before the Shelf Filing Date, the
Company shall file a "shelf" registration statement pursuant to Rule 415 under
the Securities Act with respect to the Common Shares. In its efforts to effect
the registration of Company Shares the Company will:

           (a) prepare and file with the Commission a registration statement
with respect to such securities on or before the Shelf Filing Date and use its
reasonable efforts to cause such registration statement to remain effective
until the earlier of the sale of all Restricted Stock covered thereby or the
first anniversary of the Closing Date; provided, however, that the Company may
suspend sales at any time under the registration statement immediately upon
notice to each Holder at the last known address of each Holder, for a period or
periods of time not to exceed in the aggregate ninety (90) days, if there then
exists material, non-public information relating to the Company which, in the
reasonable opinion of the Company, would not be appropriate for disclosure
during that time; provided further, that if the Company suspends such sales, it
will keep the registration statement effective for such additional time as sales
were suspended;

           (b) prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for
the period specified in paragraph (a) above;

           (c) furnish to each seller of Restricted Stock such number of
copies of the registration statement and each such amendment and supplement
thereto and the prospectus included therein (including each preliminary
prospectus) as such persons reasonably may request in order to facilitate the
public sale or other disposition of the Restricted Stock covered by such
registration statement;


                                       5


<PAGE>   6
          (d) use reasonable efforts to register or qualify the Restricted
Stock covered by such registration statement under the securities or "blue sky"
laws of such jurisdictions as the sellers of Restricted Stock reasonably shall
request, provided, however, that the Company shall not for any such purpose be
required to qualify generally to transact business as a foreign corporation in
any jurisdiction where it is not so qualified or to consent to general service
of process in any such jurisdiction;

          (e) use its reasonable best efforts to have the Restricted Stock
covered by such registration statement subject to quotation on the NASDAQ
National Market System; and

          (f) notify each seller of Restricted Stock under such
registration statement (at any time when a prospectus relating thereto is
required to be delivered under the Securities Act), of the happening of any
event of which the Company has knowledge as a result of which the prospectus
contained in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing, and promptly prepare and furnish to
such seller a reasonable number of copies of a prospectus supplemented or
amended so that, as thereafter delivered to the purchasers of such Restricted
Stock, such prospectus shall not include an untrue statement of material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances then
existing

        In connection with the registration hereunder, the sellers of Restricted
Stock will furnish to the Company in writing such information requested by the
Company with respect to themselves and the proposed distribution by them as
shall be necessary in order to assure compliance with federal and applicable
state securities laws.

        If the registration pursuant to this Section 7 involves an underwritten
public offering, the Company and each seller who wishes to participate in such
underwriting agree to enter into a written agreement with the managing
underwriter in such form and containing such provisions as are customary in the
securities business for such an arrangement between such underwriter and
companies of the Company's size and investment status.

        8. Expenses. All expenses incurred by the Company in complying with
Section 7, including, without limitation, all registration and filing fees,
printing expenses, fees and disbursements of counsel and independent public
accountants for the Company, fees and expenses incurred in connection with
complying with state securities or "blue sky" laws, fees of the National
Association of Securities Dealers, Inc., transfer taxes, fees of transfer agents
and registrars, and costs of issuance, but excluding any Selling Expenses, are
called "Registration Expenses." All underwriting discounts (if any) and selling
commissions applicable to the sale of Restricted Stock are called "Selling
Expenses."

<PAGE>   7
          The Company will pay all Registration Expenses in connection with a
registration statement under Section 7; provided, however, that all such
expenses shall be borne by the participating sellers in proportion to the number
of shares covered by such registration statement if such registration statement
is withdrawn, delayed or abandoned for any reason by the sellers. All Selling
Expenses in connection with any registration statement under Section 7 shall be
borne by the participating sellers in proportion to the number of shares sold by
each.

        9. Indemnification and Contribution.

          (a) In connection with the registration of the Restricted Stock
under the Securities Act pursuant to Section 7, the Company will indemnify and
hold harmless each seller of such Restricted Stock thereunder, its officers and
directors, each underwriter of such Restricted Stock thereunder and each other
person, if any, who controls such seller or underwriter within the meaning of
the Securities Act, against any losses, claims, damages or liabilities, joint or
several, to which such seller, officer, director, underwriter or controlling
person may become subject under the Securities Act, Exchange Act, state
securities laws or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of material fact contained in
the registration statement under which such Restricted Stock was registered
under the Securities Act pursuant to Section 7, any preliminary prospectus or
final prospectus contained therein, or any amendment or supplement thereto, (ii)
the omission or alleged omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading or (iii) any
violation by the Company or its agents of any rule or regulation promulgated
under the Securities Act, Exchange Act or state securities laws applicable to
the Company or its agents and relating to action or inaction required of the
Company in connection with such registration, and the Company will reimburse
each such seller, each such officer and director, each underwriter and each such
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission so made in conformity with information furnished
in writing to the Company by any such seller, any such underwriter or any such
controlling person, specifically for use in the registration statement.

          (b) In connection with the registration of the Restricted Stock
under the Securities Act pursuant to Section 7, each seller of such Restricted
Stock thereunder, severally and not jointly, will indemnify and hold harmless
the Company, each person, if any, who controls the Company within the meaning of
the Securities Act, each officer of the Company who signs the registration
statement, each director of the Company, each underwriter and each person who
controls any underwriter within the meaning of the Securities Act, against all
losses, claims, damages or liabilities, joint or several, to which the Company
or such officer, director, underwriter or controlling person may become subject
under the Securities Act or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) the failure of 


                                       7


<PAGE>   8
such seller to comply with the provisions of Section 12 herein or (ii) any
untrue statement or alleged untrue statement of any material fact contained in
the registration statement, any preliminary prospectus or final prospectus
contained therein, or any amendment or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and will reimburse the Company and each such officer, director,
underwriter and-controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action; provided, however, that such seller will be
liable hereunder in any such case if and only to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in reliance upon
and in conformity with information pertaining to such seller, furnished to the
Company in writing by such seller, specifically for use in the registration
statement; and provided, further, that in no event shall any indemnity under
this subsection 9(b) exceed the gross proceeds from the offering received by
such seller(s).

        (c) Promptly after receipt by an indemnified party hereunder of
notice of the commencement of any action, such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof, but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 9 and shall only relieve
it from any liability which it may have to such indemnified party under this
Section 9 if and to the extent the indemnifying party is prejudiced by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate in and, to the extent it
shall wish, to assume and undertake the defense thereof with counsel
satisfactory to such indemnified party, and, after notice from the indemnifying
party to such indemnified party of its election so to assume and undertake the
defense thereof and the approval by the indemnified party of the counsel chosen
by the indemnifying party, the indemnifying party shall not be liable to such
indemnified party under this Section 9 for any legal expenses subsequently
incurred by such indemnified party in connection with the defense thereof other
than reasonable costs of investigation and of liaison with counsel so selected;
provided, however, that, if the defendants in any such action include both the
indemnified party and the indemnifying party and if the interests of the
indemnified party reasonably may be deemed to conflict with the interests of the
indemnifying party, the indemnified party shall have the right to select a
separate counsel and to assume such legal defenses and otherwise to participate
in the defense of such action, with the expenses and fees of such separate
counsel and other expenses related to such participation to be reimbursed by the
indemnifying party as incurred.

        (d) In order to provide for just and equitable contribution to
joint liability in any case in which either (i) any Holder of Restricted Stock
exercising rights under this Agreement, or any controlling person of any such
Holder, makes a claim for indemnification pursuant to this Section 9, but it is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time 


                                       8


<PAGE>   9
to appeal or the denial of the last right of appeal) that such indemnification
may not be enforced in such case notwithstanding the fact that this Section 9
provides for indemnification in such case, or (ii) contribution under the
Securities Act may be required on the part of any such selling Holder or any
such controlling person in circumstances for which indemnification is provided
under this Section 9; then, and in each such case, the Company and such Holder
will contribute to the aggregate losses, claims, damages or liabilities to which
they may be subject (after contribution from others) in proportion to the
relative fault of the Company, on the one hand, and each Holder, severally, on
the other hand; provided, however, that, in any such case, no person or entity
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any person or entity
who was not guilty of such fraudulent misrepresentation and; provided, further,
that in no event shall any indemnity under this subsection 9 (d) exceed the
gross proceeds from the offering received by such Holder.

          (e) The indemnities provided in this Section 9 shall survive the
transfer of any Restricted Stock by any Holder.

        10. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the
Securities Act and any other rule or regulation thereunder that may at any time
permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to:

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

          (b) maintain registration of its Common Stock under Section 12 of
the Exchange Act;

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

          (d) furnish to any Holder, so long as the Holder owns any
Restricted Securities, forthwith upon request: (i) a written statement by the
Company that it has complied with the reporting requirements of Rule 144, (ii) a
copy of the most recent annual or quarterly report of the Company and such other
reports and documents so filed by the Company; and (iii) such other information
as may be reasonably requested in availing any Holder of any rule or regulation
under the Securities Act which permits the selling of any such securities
without registration or pursuant to such form.

        11. Changes in Common Stock. If, and as often as, there is any change in
the Common Stock by way of a stock split, stock dividend, combination or
reclassification, or through a merger, consolidation, reorganization or
recapitalization, or by any other means, appropriate adjustment shall be made in
the provisions hereof so that the rights and privileges granted hereby shall
continue with respect to the Common Stock as so changed.

<PAGE>   10
        12. Sellers' Conduct. With respect to any sale of Common Shares pursuant
to Section 7, each Holder understands and agrees as follows:

           (a) Holder will carefully review the information concerning
Holder contained in the registration statement (if any) and will promptly notify
the Company if such information is not complete and accurate in all respects,
including having properly disclosed any position, office or other material
relationship within the past three years with the Company or its affiliates;

           (b) Holder agrees to sell Holder's Common Shares only in the
manner set forth in the registration statement;

           (c) Holder agrees to comply with the anti-manipulation rules
under the Exchange Act in connection with purchases and sales of securities of
the Company during the time the registration statement remains effective;

           (d) Holder agrees to only sell shares in a jurisdiction after
counsel for the Company has advised that such sale is permissible under the
applicable state securities or "Blue Sky" laws;

           (e) Holder agrees to comply with the prospectus delivery
requirements of the Exchange Act;

           (f) Holder agrees to promptly notify the Company of any and all
planned sales and completed sales of shares;

           (g) Holder agrees to suspend sales during the periods when sales
are to be suspended pursuant to Section 7(a) herein; and

            (h) Holder agrees not to take any action that could adversely
affect the ability of the Company to account for the business combination to be
effected by the Merger as a pooling of interests.

        13. Miscellaneous.

            (a) All covenants and agreements contained in this Agreement by
or on behalf of any of the parties hereto shall bind and inure to the benefit of
the respective successors and assigns of the parties hereto (including without
limitation transferees of any Restricted Stock, provided, that such transferee
executes a counterpart signature page to this Agreement), whether so expressed
or not.

            (b) All notices, requests, consents and other communications
hereunder shall be in writing and shall be mailed by certified or registered

of any facts, claim or demand which has given rise to, or could reasonably give
rise to, an Indemnification Claim under Section 1.1(a) or 1.1(b), Parent may

claim is not provided by the Indemnification Representative within such 45-day
period, Parent shall give written notice to the Escrow Agent and the

whereupon the validity and stated amount of the claim and, if the Parent
Threshold has been met, the number of Indemnification Escrow Shares to be
delivered will be deemed to have been accepted (such claims being referred to
herein as "Accepted Claims"). If a notice of objection is provided, the
Indemnification Representative and Parent shall have sixty (60) days in which
they shall attempt to agree on the rights of both parties. If the
Indemnification Representative and Parent shall so agree, a memorandum setting
forth such agreement shall be prepared and furnished to the Escrow Agent who
shall be entitled to rely upon such memorandum. If after 60 days no agreement is

have forty-five (45) days from the date a Notice of Claim is given within which
to object, by written notice to Parent, to any Indemnification Claim (a
"Principal Shareholder Challenged Claim"). If notice of objection to any such
claim is not provided by a Principal Shareholder, the validity and stated amount
of the claim will be deemed to have been accepted and, if the Principal
Shareholder Threshold has been met, payment in the amount of the Loss set forth
in the Notice of Claim shall be delivered to Parent not later than five (5) days
after the expiration of such 45 day period. The parties shall submit the matter
of a Principal Shareholder Challenged Claim to arbitration in accordance with
Article VI hereof. If a Notice of Claim sets forth a Third Party Claim, the
provisions of Section 1.5(b) shall also apply.

        1.4 Company Shareholder Claims.

        (a) At any time after obtaining knowledge of any facts, claim or demand
which has given rise to, or could reasonably give rise to, an Indemnification

Notice of Claim whether or not the Company Threshold has been reached. The
Notice of Claim must be given on or prior to the Escrow Termination Date, and

the Company Shareholders.

        (b) Upon receipt of a Notice of Claim, Parent shall, subject to the
provisions of Section 1.4(c), pay the Indemnification Representative in
immediately available funds within five (5) days of the expiration of the
forty-five (45) day notice period described in Section 1.4(c) an amount equal to

        (c) Parent shall have forty-five (45) days from the date a Notice of

stated amount of the claim will be deemed to have been accepted and payment in
the amount of the Loss set forth in the Notice of Claim shall be delivered to
the Indemnification Representative not later than five (5) days after the
expiration of such 45 day period. The parties shall submit the matter of a
Parent Challenged Claim to arbitration in accordance with Article VI hereof. If
a Notice of Claim sets forth a Third Party 


                                       4


<PAGE>   5
Claim, the provisions of Section 1.5(b) shall also apply.

        1.5 Procedural Matters.

        (a) Notice Delivery. So long as the Notice of Claim is given by the
Indemnified Party in accordance with Section 1.3(a) or 1.4(a), no failure or
delay by the Indemnified Party in the giving of a Notice of Claim shall reduce
or otherwise affect the Indemnified Party's right to indemnification hereunder.
Notice of Claim shall be deemed to be given as of:

                (x) the second business day after the date of the postmark on
        the registered or certified mail (postage prepaid, return receipt
        requested) containing the Notice of Claim; or

                (y) if the Notice of Claim is personally delivered, the date of
        such personal delivery.

        (b) Third Party Claims. In the event of a Third Party Claim, the
Indemnifying Party shall have the right, but not the obligation, exercisable by
written notice to the Indemnified Party within ten (10) days of the date of the
Notice of Claim concerning the commencement or assertion of any Third Party
Claim, to participate in the defense of such Third Party Claim. The Indemnified
Party shall not settle such Third Party Claim without the prior written consent
of the Indemnifying Party, which consent shall not be unreasonably withheld or
delayed. Notwithstanding the foregoing, the Indemnified Party shall have the
right to pay or settle any Third Party Claim at any time, provided that in such
event it waives any right to indemnification therefor by the Indemnifying Party.
Within ten (10) days of the date a court of competent jurisdiction or arbitrator
shall determine that the Indemnified Party is liable for all or a portion of the
monetary liability arising out of any Third Party Claim or a settlement is
reached, the Indemnifying Party shall pay such claim as if such claim had been
accepted in accordance with the other provisions hereof unless an appeal is made
in accordance with the next sentence. If the Indemnifying Party desires to
appeal from an adverse judgment, then the Indemnifying Party shall post and pay
the cost of the security or bond required to stay execution of the judgment
pending appeal. Upon the payment in full by the Indemnifying Party of such
amounts, the Indemnifying Party shall succeed to the rights of such Indemnified
Party, to the extent not waived in settlement, against the third party who made
such Third Party Claim. The Indemnifying Party and Indemnified Party shall
submit disputes regarding any payments due under this Section 1.5(b) to
arbitration in accordance with Article VI. The Indemnifying Party and the
Indemnified Party shall cooperate in the defense or prosecution of any Third
Party Claim and shall furnish or cause to be furnished such records, information
and testimony, and attend such conferences, discovery proceedings, hearings,
trials or appeals, as may be requested in connection therewith.

                             ESTABLISHMENT OF ESCROW

        2.1 Escrow Shares. On this date, Parent has executed and delivered to
the Escrow Agent a stock certificate in negotiable form representing the
Indemnification Escrow Shares. The Escrow Agent acknowledges receipt of the
Indemnification Escrow Shares and agrees to hold 


                                       5


<PAGE>   6
and disburse the Indemnification Escrow Shares for the benefit of Parent and the
Company Shareholders in accordance with the provisions of this Agreement.

        2.2 Shareholder Percentage Interests. Attached as Schedule I hereto is a
schedule showing for each Company Shareholder (i) the respective percentage
interest (the "Percentage Interest") of each such Company Shareholder in the
Indemnification Escrow Shares, and (ii) the corresponding aggregate maximum
number of Indemnification Escrow Shares issuable to each Shareholder, subject to
the adjustments provided herein.

        2.3 Delivery of IRS Form W-9. Upon the request of the Escrow Agent, each
Company Shareholder will deliver to the Escrow Agent such Shareholder's current
IRS Form W-8 or 9. Company and Parent will use its reasonable efforts to assist
the Escrow Agent in obtaining such IRS Forms W-8 or 9 from the Company
Shareholders.

        2.4 Escrow Termination Procedures.

        (a) On the Escrow Termination Date, Parent and the Indemnification
Representative shall prepare, execute and deliver to the Escrow Agent a
certificate instructing the Escrow Agent as to the number of Indemnification
Escrow Shares, if any, to be retained in escrow following the Escrow Termination
Date. Such number shall be equal to the quotient of the dollar amount of all
Challenged Claims and pending Indemnification Claims which have not been finally
determined (collectively, "Pending Claims") divided by the Parent Average
Closing Price (rounded up to the nearest whole share). The "dollar amount" of
any Pending Claim shall be calculated assuming the maximum possible exposure set
forth in the Notice of Claim; provided, however, that, with respect to a Pending
Claim for which legal action has not been taken against the Indemnified Party
within two years following the Notice of Claim (the "Period"), then the dollar
amount of such Pending Claim shall be as agreed upon by Parent and the
Indemnification Representative, and if they cannot agree within ninety (90) days
of the end of the Period, then such dollar amount shall be determined by
arbitration in accordance with Article VI hereof. The Escrow Agent shall retain
in escrow after the Escrow Termination Date the number of Indemnification Escrow
Shares as are set forth in such certificate of Parent and Indemnification
Representative.

        (b) As promptly as practicable after the Escrow Termination Date, the
Escrow Agent shall deliver to the Company Shareholders the balance of the
Indemnification Escrow Shares not delivered to the Parent Parties or retained in
escrow pursuant to Section 2.4(a). Each Company Shareholder shall receive his or
her Percentage Interest of such distribution.

        (c) Indemnification Escrow Shares that are not distributed to the
Company Shareholders on the Escrow Termination Date because they have been
retained pursuant to Section 2.4(a) shall be distributed as follows: Upon
receipt by the Escrow Agent of a certificate of Parent and Indemnification
Representative setting forth the amount of the final distribution to Parent and
confirming that all Pending Claims have been finally determined, the balance of
all Indemnification Escrow Shares shall be delivered to the Company Shareholders
in accordance with Section 2.4(b).

        3.1 Voting Rights; Distributions. Unless and until the Indemnification
Escrow Shares are delivered to Parent pursuant to this Agreement, Parent shall
cause its stock transfer agent to register such shares in the respective names
of the Company Shareholders in accordance with their respective Percentage
Interests, who shall be entitled to vote their respective Indemnification Escrow
Shares. All cash dividends or distributions of assets declared by Parent with
respect to its Common Stock prior to the Escrow Termination Date shall be
payable directly to the Company Shareholders as if each had received all of the
shares of Parent Common Stock deliverable to such shareholder at the Effective
Time of the Merger and no shares had been placed into escrow under this
Agreement (subject to reduction to reflect the delivery of Indemnification
Escrow Shares to Parent under this Agreement).

        3.2 Additional Shares. All shares of Parent Common Stock relating to
Indemnification Escrow Shares still held by the Escrow Agent under this
Agreement and resulting from conversion, stock dividend, stock split,
reclassification, recapitalization or corporate reorganization of Parent, shall
be delivered to the Escrow Agent when deliverable to holders of other
outstanding shares of Parent Common Stock, shall be allocated according to the
Percentage Interest of each Company Shareholder and shall constitute additional
Indemnification Escrow Shares.

        3.3 Interest in Escrow Shares. The interest of the Company Shareholders
in the Indemnification Escrow Shares (until released to them hereunder) is
nonassignable and shall be transferable only by operation of law.

escrow pursuant to this Agreement, the Company Shareholders, and each of them,
will be represented by the Indemnification Representative who is empowered to
give any and all notices and instructions and take any and all action for and on
behalf of the Company Shareholders, and each of them, under this Agreement. The
Company Shareholders will have the right to remove the Indemnification
Representative and, upon such removal or, in the event of the Indemnification
Representative's death or resignation, to appoint as the new Indemnification
Representative any Company Shareholder at any time and from time to time during
the period when any shares are held in escrow, by a vote of Company Shareholders
holding a majority interest in the Indemnification Escrow Shares held in escrow
at such time evidenced by a writing executed by such majority Company
Shareholders. The appointment of a new Indemnification Representative will be of

this Agreement until three days after the later of the dates when Parent or the
Escrow Agent is deemed to have received written notice of such appointment,
which notice must include at least: (i) the identity and address of the new
Indemnification Representative and a statement that such Indemnification
Representative has been appointed by a vote of Company Shareholders holding a
majority interest in the Indemnification Escrow Shares then held in escrow; (ii)
the duly acknowledged signatures of each of the Company Shareholders voting for

non-signing Company Shareholder has been notified in writing of the appointment
of the new Indemnification Representative. Parent and the Escrow Agent will be
entitled to rely on any notice received in such form without conducting an
investigation of the contents thereof.

received from, the Indemnification Representative will be deemed to be action
by, or notice or instruction from, each and all of the Company Shareholders.

received from any Company Shareholder other than the then-acting Indemnification
Representative with regard to this Agreement prior to the Escrow Termination
Date.

which he or she in good faith believes to be genuine.

may deem necessary to advise him or her properly with respect to his or her
rights and obligations hereunder and to evaluate Indemnification Claims and to

reasonable expenses and fees of such counsel and experts, and any reasonable,
documented out of pocket expenses which the Indemnification Representative

        5.5 Duties. The duties and responsibilities of the Escrow Agent shall be
limited to those expressly set forth in this Agreement and instructions given to
the Escrow Agent pursuant to this Agreement, and the Escrow Agent shall neither
be subject to, have any liability under, nor obligated to recognize, any other
agreement between any or all of the parties hereto even though reference thereto
may be made herein; provided, however, with the written consent of the Escrow
Agent, this Agreement may be amended at any time by an instrument in writing

discretion, to disregard any and all notices or instructions given by any of the
parties hereto or by any other person, firm or corporation, except only such
notices or instructions as are herein expressly provided for in this Agreement

                                       9


<PAGE>   10
of any such property shall be stayed or enjoined by any court order, or in case
any order, judgment or decree shall be made or entered by any court affecting
such property or any part thereof, then and in any of such events, the Escrow
Agent is authorized, in its sole discretion, to rely upon and comply with any
such order, writ, judgment or decree which the Escrow Agent is advised by legal
counsel of its own choosing is binding upon it; and if the Escrow Agent complies
with any such order, writ, judgment or decree, it shall not be liable to any of
the parties hereto or to any other person, firm or corporation by reason of such
compliance even though such order, writ, judgment or decree may be subsequently
reversed, modified, annulled, set aside or vacated.

        5.8 Resignation. The Escrow Agent may resign by giving twenty (20) days
advance written notice to Parent and the Indemnification Representative and

directed and empowered to file an interplea motion and deliver all items held by
it to a court of competent jurisdiction.

the Escrow Agent, the Parent agrees to indemnify and hold the Escrow Agent
harmless as to and against any loss, liability or expense incurred by it to any
person, firm or corporation by reason of its having accepted the same or in
carrying out any of the terms hereof (except as such liability may arise out of
or be based upon the gross negligence or willful misconduct of the Escrow
Agent), and to reimburse the Escrow Agent for all its reasonable expenses,
including, among other things, counsel fees and court costs, incurred by reason
of its position hereunder or actions taken pursuant hereto. The indemnity of
this paragraph shall survive the resignation or substitution of the Escrow Agent
or the termination of this Escrow Agreement.

        5.10 Termination. The obligations of the Escrow Agent shall terminate
upon the disbursement of all of the Indemnification Escrow Shares.
Notwithstanding any termination of this Escrow Agreement, the provisions of

                               DISPUTE RESOLUTION

        6.1 Submission of Disputes. Except as provided in Section 6.3, all
disputes related to the obligations of all or any of the parties hereto under
the provisions of this Agreement shall be submitted to, and settled by,
arbitration in Seattle, Washington, in accordance with the Commercial Rules of
the American Arbitration Association. The dispute shall be submitted to one
arbitrator agreed to by the Indemnified Party and the Indemnifying Party. If the
Indemnified Party and the Indemnifying Party cannot agree on one arbitrator, one
arbitrator will be selected by each party, with the two selected arbitrators
then selecting a third arbitrator.

        6.2 Fees, Expenses and Awards. The fees and expenses of the arbitration
or arbitrators shall be paid by the Indemnifying Party unless the
indemnification obligation is reduced to less than 80% of the amount in the
related Notice of Claim and in such event the fees

Indemnifying Party. Any arbitration award may be entered in and enforced by any
court having jurisdiction thereover and the parties hereby consent and commit
themselves to the jurisdiction of the courts of the State of Washington for the
purposes of the enforcement of any arbitration award.

        6.3 Disputes as to Duties of Escrow Agent. Any dispute which may arise
with respect to the duties of the Escrow Agent hereunder shall be settled by the
mutual agreement of the parties concerned. The Escrow Agent shall be under no
duty to institute or defend any proceeding unless the subject of such proceeding
is part of its duties hereunder. In the event adverse claims or demands are made
upon any of the Indemnification Escrow Shares, or in the event that the Escrow
Agent, in good faith, is in doubt as to what action it should take hereunder,
the Escrow Agent may, at its option, file a suit as interpleader in a court of
appropriate jurisdiction, or refuse to comply with any claims or demands on it,
or refuse to take any other action hereunder, so long as such dispute shall
continue or such doubt shall exist. The Escrow Agent shall be entitled to
continue so to refrain from acting until (i) the rights of all parties have been
fully and finally adjudicated by a court of appropriate jurisdiction, or (ii)
all differences and doubt shall have been resolved by agreement among all of the
