                             ARTICLE II: THE MERGER

        2.1    THE MERGER. At the Effective Time and upon and subject to the
terms and conditions of this Agreement, IST will be merged with and into Merger
Sub, which shall be the Surviving Corporation in the Merger and shall continue
to be governed by the Laws of the State of Oregon, and the separate existence of
IST shall cease. The Merger shall be pursuant to the provisions of, and shall be
with the effects provided in, the OBCA.

        2.2    EFFECTIVE TIME. Subject to the terms and conditions of this
Agreement, on the Closing Date, Merger Sub and IST will cause the Articles of
Merger to be executed, delivered and filed as provided in the OBCA. The Merger
shall become effective at the time of the filing of the Articles of Merger with
the Oregon Secretary of State or at such later time as Microfield and IST may
agree and as may be set forth in the Articles of Merger.

        2.3    ARTICLES OF INCORPORATION OF SURVIVING CORPORATION. The Articles
of Incorporation of Merger Sub in effect immediately prior to the Effective Time
shall be the Articles of Incorporation of the Surviving Corporation until
amended in accordance with the OBCA, provided that Article I of the Articles of
Incorporation of Merger Sub shall be amended at the Effective Time to change the
name of Merger Sub to "Innovative Safety Technologies, Inc."

        2.4    BYLAWS OF SURVIVING CORPORATION. The Bylaws of Merger Sub in
effect immediately prior to the Effective Time shall be the Bylaws of the
Surviving Corporation until amended in accordance with the OBCA.

        2.5    DIRECTORS AND OFFICERS OF SURVIVING CORPORATION. The duly
qualified and acting directors and officers of Merger Sub immediately prior to
the Effective Time shall be the directors and officers of the Surviving
Corporation, to hold office as provided in the Bylaws of the Surviving
Corporation.

        2.6    CONVERSION OF IST MEMBERSHIP INTERESTS. At the Effective Time, by
virtue of the Merger and without any action on the part of Merger Sub, IST,
Microfield or the Members, each holder of IST Membership Interests issued and
outstanding at the Effective Time shall be entitled to, and such interests will
be converted into the right to receive, the number of shares of Microfield
Common Stock as determined by the following formula:

               X = I x 1,818,181

               Where:

               "X" is the number of shares of Microfield Common Stock to be
               received by a Member and

               "I" is the percentage of the issued and outstanding IST
               Membership Interests held by such Member immediately before the
               Effective Time.


                                       5


        2.7    PROCEDURE FOR PAYMENT.

               (a)    SURRENDER OF MEMBERSHIP INTERESTS. From and after the
Effective Time, each holder of IST Membership Interests outstanding immediately
prior to the Effective Time, upon surrender to Microfield or its agent
designated for such purpose of any letters of transmittal or other documents as
may be reasonably requested by Microfield or its agent, shall be entitled to
receive a certificate representing the number of shares of Microfield Common
Stock into which such IST Membership Interests shall have been converted
pursuant to the provisions of Section 2.6.

               (b)    NO FRACTIONAL SHARES. No certificates or scrip evidencing
fractional shares of Microfield Common Stock shall be issued in the Merger, and
such fractional share interests will not entitle the owner thereof to any rights
as a shareholder of Microfield. Merger Consideration to be paid to each Member
will be rounded to the nearest whole share.

               (c)    NO FURTHER RIGHTS IN IST MEMBERSHIP INTERESTS. All shares
of Microfield Common Stock issued upon conversion of the IST Membership
Interests in accordance with the terms of this Agreement shall be deemed to have
been issued (and paid) in full satisfaction of all rights pertaining to the IST
Membership Interests.

        2.8    MEMBERSHIP TRANSFER BOOKS. At the Effective Time, the membership
transfer books of IST shall be closed and there shall be no further registration
of transfers of IST Membership Interests thereafter on the records of IST. From
and after the Effective Time, the holders of IST Membership Interests
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to such IST Membership Interests except as otherwise
provided in this Agreement or by Law.

        2.9    UNREGISTERED SHARES. The Members have been informed by Microfield
that the Microfield Common Stock conveyed hereunder as Merger Consideration has
not been registered under the Securities Act of 1933 (the "SECURITIES ACT") and
that such Microfield Common Stock must be held for the time required by Rule 144
promulgated under the Securities Act ("RULE 144"), unless (i) the distribution
for sale of the Microfield Common Stock has been registered under the Securities
Act, (ii) a sale of the Microfield Common Stock is made in conformity with the
provisions of Rule 144, or (iii) in the opinion of counsel, which opinion is
reasonably acceptable to Microfield, some other exemption from registration is
available with respect to any such sale, transfer or other disposition of such
Microfield Common Stock.

        2.10   STOCK CERTIFICATE LEGENDS. Each Member acknowledges and
understands that stock transfer instructions will be given to Microfield's
transfer agent with respect to the Merger Consideration and that there will be
placed on the certificates for such shares, or any substitution therefor, the
following legend:

                      "The securities evidenced by this certificate have not
               been registered under the Securities Act of 1933 (the "Act") or
               any applicable state law, and no interest therein may be sold,
               distributed, assigned, offered, pledged or otherwise transferred


                                       6


               unless (a) there is an effective registration statement under
               such Act and applicable state securities laws covering any such
               transaction involving these securities or (b) the Company
               receives an opinion of legal counsel for the holder of these
               securities (concurred in by legal counsel for the Company) to the
               effect that such transaction is exempt from registration or the
               Company otherwise satisfies itself that such transaction is
               exempt from registration."

        2.11   APPOINTMENT OF REPRESENTATIVE. (a) The Representative is hereby
appointed as representative of the Members for purposes of this Agreement.
Member approval of this Agreement shall include confirmation of the authority of
the Representative. Microfield, Merger Sub and IST may rely upon the acts of the
Representative for all purposes permitted hereunder.

               (b)    The Representative shall have full power of substitution

with this Agreement. The Representative's power shall include the following
powers, without limitation: the power to act for the Members with regard to the
indemnification obligations hereunder; the power to compromise any claim on
behalf of the Members and to transact matters of litigation or arbitration in
connection with this Agreement; the power to do or refrain from doing all such
further acts and things on behalf of the Members that the Representative deems

with any claims hereunder.

               (c)    If the Representative resigns, dies or otherwise becomes

be determined in accordance with the proportionate interests of each Member in
the Microfield Common Stock received by the Members in the Merger).

               (d)    The Representative shall act for the Members hereunder in
the manner the Representative believes to be in the best interest of the Members
and consistent with his obligations hereunder, but shall have no duties or
obligations except as specifically set forth herein. In acting as representative
of the Members, the Representative may rely upon, and shall be protected in

certificate of auditors or other certificate, statement, instrument, opinion,
report, notice, request, consent, order arbitrator's award, appraisal, bond or
other paper or documents reasonably believed by him to be genuine and to have
been signed or presented by the proper party or parties. The Representative
shall not be personally liable to the Members for any action taken, suffered or
omitted by him in good faith and reasonably believed by him to be authorized or
within the discretion of the rights or powers conferred upon him by this Section
2.11. The Representative may consult with counsel and any advice of such counsel

duties as Representative either directly or by or through his agents or
attorneys, and

jurisdiction in which the character of the property owned, leased or operated by
it or the nature of the business conducted by it makes such qualification or
licensing necessary, except where the failure to be so duly qualified or

Material Adverse Effect. IST has delivered to Microfield accurate and complete
copies of the Articles of Organization and Operating Agreement, as currently in
effect, of IST.

        3.2    CAPITALIZATION. As of the date hereof, the IST Membership

this Agreement and the completion of the transactions contemplated hereby,
including, but not limited to, the Merger, have been duly and validly authorized
by IST's manager, and no other limited liability company proceedings on the part
of IST are necessary to authorize the execution and delivery of this Agreement
or to complete the transactions contemplated hereby (other than adoption of this
Agreement by the Members in accordance with the OLLCA and the Operating
Agreement of IST). This Agreement has been duly and validly executed and
delivered by IST and constitutes the legal, valid and binding agreement of IST,
enforceable against IST in accordance with its


                                       8

Enforceability Exceptions.

        3.5    GOVERNMENTAL APPROVALS. No consent, approval, waiver or

Governmental Authority, on the part of IST is required in connection with the
execution or delivery by IST of this Agreement or the completion by IST of the
transactions contemplated hereby other than (a) the filing of the Articles of
Merger with the Secretary of State of Oregon in accordance with the OBCA, and
(b) those Consents that, if they were not obtained or made, would not reasonably
be expected to have a Material Adverse Effect.

        3.6    NO VIOLATIONS. The execution and delivery of this Agreement, the
completion of the transactions contemplated hereby and compliance by IST with
any of the provisions hereof will not (a) conflict with or result in any breach
of any provision of the Articles of Organization or Operating Agreement of IST,
(b) require any Consent under or result in a violation or breach of, or
constitute (with or without notice or lapse of time or both) a default (or give
rise to any right of termination, cancellation or acceleration) under any of the
terms, conditions or provisions of, any Material Contract, (c) result in the
creation or imposition of any Lien upon any of the assets of IST or (d) subject
to obtaining the Consents from Governmental Authorities referred to in Section
3.5, violate any applicable provision of any Law to which IST or its assets or
properties are subject, except, in the case of each of clauses (b), (c) and (d)

expected to have a Material Adverse Effect.

business; (g) any payments to IST employees or service providers outside of
IST's regular course of business; or (h) any other action or event, involving an
amount exceeding $5,000 that would have required the consent of Microfield
pursuant to Section 5.1 had such action or event occurred after the date of this
Agreement.


                                       9

connection with the operation of its business, (b) IST is not in violation of
any Permit and (c) no proceedings are pending or, to the Knowledge of IST,
threatened, to revoke or limit any Permit, except, in the case of each of
clauses (a) and (b), where the absence or violation would not reasonably be
expected to have a Material Adverse Effect.

        3.12   LITIGATION. There is no suit, action or proceeding ("LITIGATION")
pending or, to the Knowledge of IST, threatened against IST, nor is there any
judgment, decree, injunction, rule or order of any Governmental Authority

all the Material Contracts are valid and binding and are in full force and
effect and enforceable against IST in accordance with their respective terms,
subject to the Enforceability Exceptions, and IST is not in violation or breach
of or default under any Material Contract, except where the failure to be in

expected to have a Material Adverse Effect. To the Knowledge of IST, no party is
in default, violation or breach of any Material Contract where such violation or
breach would reasonably be expected to have a Material Adverse Effect.


                                       10

subject IST or any ERISA Affiliate, directly or indirectly, to a tax, penalty or
other liability for prohibited transactions under ERISA or Section 4975 of the

expected to result in a Material Adverse Effect; (iv) to the Knowledge of IST,

        7.5    INDEMNIFICATION PROCEDURE.

               (a)    THIRD PARTY CLAIMS.

                      (i)    Each indemnified party will, with reasonable
promptness after obtaining knowledge thereof, provide the indemnifying party
with written notice of all third party actions, suits, proceedings, claims,
demands or assessments that may be subject to the indemnification provisions of
this Section 7 (collectively, "THIRD PARTY CLAIMS"), including, in reasonable
detail, the basis for the claim, the nature of Damages and a good faith estimate
of the amount of Damages.

                      (ii)   The indemnifying party or, in the case where the
Members are the indemnifying party, the Representative, shall have 15 days after
receipt of the claim notice to notify the indemnified party in writing whether
the indemnifying party agrees that the claim is subject to this Section 7 and,
if so, whether the indemnifying party elects to undertake, conduct


                                       26


and control, through counsel of its choosing (subject to the consent of the
indemnified party, such consent not to be withheld unreasonably), and at its
sole risk and expense, the good faith settlement or defense of the Third Party
Claim.

                      (iii)  If within 15 days after receipt of the claim notice
the indemnifying party or, in the case where the Members are the indemnifying
party, the Representative, notifies the indemnified party that the indemnifying
party elects to undertake the good faith settlement or defense of the Third
Party Claim, the indemnified party shall reasonably cooperate with the
indemnifying party in connection therewith including, without limitation, by
making available to the indemnifying party all relevant information material to
the defense of the Third Party Claim. The indemnified party shall be entitled to
participate in the settlement or defense of the Third Party Claim through
counsel chosen by the indemnified party, at its expense, and to approve any
proposed settlement that would impose any obligation or duty on the indemnified
party, which approval may, in the sole discretion of the indemnified party, be
withheld. So long as the indemnifying party is contesting the Third Party Claim
in good faith and with reasonable diligence, the indemnified party shall not pay
or settle the Third Party Claim. 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.

                      (iv)   If the indemnifying party or, in the case where the
Members are the indemnifying party, the Representative, does not provide notice
that it elects to undertake the good faith settlement or defense of the Third
Party Claim, or if the indemnifying party or, in the case where the Members are
the indemnifying party, the Representative, fails to contest the Third Party
Claim or undertake or approve settlement, in good faith and with reasonable
diligence, the indemnified party shall thereafter have the right to contest,
settle or compromise the Third Party Claim at its exclusive discretion, at the
risk and expense of the indemnifying party and the indemnifying party will
thereby waive any claim, defense or argument that the indemnified party's
defense or settlement of such Third Party Claim is in any respect inadequate or
unreasonable.

                      (v)    A party's failure to give timely notice will not
constitute a defense (in part or in whole) to any claim for indemnification by
such party, except if, and only to the extent that, such failure results in any
material prejudice to the indemnifying party.

               (b)    NON-THIRD PARTY CLAIMS.

                      (i)    Each indemnified party will, with reasonable
promptness, deliver to the indemnifying party written notice of all claims for
indemnification under this Section 7, other than Third Party Claims, including,
in reasonable detail, the basis for the claim, the nature of Damages and a good
faith estimate of the amount of Damages.

                      (ii)   The indemnifying party or, in the case where the
Members are the indemnifying party, the Representative, shall have 30 days after
receipt of the claim notice to notify the indemnified party in writing whether
the indemnifying party accepts liability for all or any part of the Damages
described in the claim notice. If the indemnifying party or, in the case


                                       27


where the Members are the indemnifying party, the Representative, does not so
notify the indemnified party the indemnifying party shall be deemed to accept
liability for all the Damages described in the claim notice.

                      (iii)  A party's failure to give timely notice will not
constitute a defense (in part or in whole) to any claim for indemnification by
such party, except if, and only to the extent that, such failure results in any
material prejudice to the indemnifying party.

        7.6    PAYMENT WITH MICROFIELD COMMON STOCK. Any Damages payable
hereunder may be paid by delivery of the equivalent value of Microfield Common
Stock using the Microfield Stock Value. In the case of payment by Members, such
payment will be accomplished by delivery of certificates representing shares of
Microfield Common Stock together with duly executed stock powers to Mellon
Investor Services, LLC, the transfer agent for Microfield Common Stock, or its
successor, with instructions to transfer and deliver to Microfield a stock
certificate evidencing the requisite number of shares to be transferred to
Microfield or instructing that the shares be cancelled, as the case may be, with
certificates representing the balance to be returned to Members. In the case of
payment by Microfield, such payment will be accomplished by the issuance and
delivery of certificates representing the requisite number of shares of
Microfield Common Stock to each Member.

        7.7    RIGHTS NOT EXCLUSIVE. An indemnified party's rights to
indemnification under this Section 7 are in addition to, and not in lieu of, any
other rights to which the indemnified party may be entitled at law or in equity.

                                       29

herein:

               (a)    by mutual written consent of Microfield and IST;

               (b)    by either Microfield or IST if (i) any Governmental
Authority shall have issued an order, decree or ruling or taken any other action
permanently enjoining, restraining or otherwise prohibiting the completion of
the transactions contemplated by this Agreement and such order, decree or ruling
or other action shall have become final and nonappealable, or (ii) the Members
do not approve the Merger at the Special Meeting;

               (c)    by Microfield if:

                      (i)    IST shall have breached or failed to perform in any
material respect any of its covenants or other agreements contained in this
Agreement, which breach or failure to perform is incapable of being cured or has
not been cured within 5 days after the giving of written notice thereof to IST;

                      (ii)   any representation or warranty of IST shall not
have been true and correct when made (without for this purpose giving effect to
qualifications of materiality contained in such representation and warranty), if
such failure to be true and correct, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect;


                                       30


                      (iii)  any representation or warranty of IST shall cease
to be true and correct at any later date (without for this purpose giving effect
to qualifications of materiality contained in such representation and warranty)
as if made on such date (other than representations and warranties made as of a
specified date) other than as a result of a breach or failure to perform by
Microfield of any of its covenants or agreements under this Agreement if such
failure to be true and correct, individually or in the aggregate, would
reasonably be expected to have a Material Adverse Effect; provided, however,
that such representation or warranty is incapable of being cured or has not been
cured within 5 days after the giving of written notice thereof to IST;

                      (iv)   since June 30, 2002, IST shall have suffered a
Material Adverse Change;

               (d)    by IST if:

                      (i)    Microfield or Merger Sub shall have breached or
failed to perform in any material respect any of its representations,
warranties, covenants or other agreements contained in this Agreement, which
breach or failure to perform is incapable of being cured or has not been cured
within 5 days after the giving of written notice thereof to Microfield;

                      (ii)   any representation or warranty of Microfield or
Merger Sub shall not have been true and correct when made (without for this
purpose giving effect to qualifications of materiality contained in such
representation and warranty), if such failure to be true and correct,
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect;

                      (iii)  any representation or warranty of Microfield or
Merger Sub shall cease to be true and correct at any later date (without for
this purpose giving effect to qualifications of materiality contained in such
representation and warranty) as if made on such date (other than representations
and warranties made as of a specified date) other than as a result of a breach
or failure to perform by IST of any of its covenants or agreements under this
Agreement if such failure to be true and correct, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect;
provided, however, that such representation or warranty is incapable of being
cured or has not been cured within 5 days after the giving of written notice
thereof to Microfield or Merger Sub;

                      (iv)   since June 29, 2002, Microfield shall have suffered
a Material Adverse Change.

               (e)    by either Microfield or IST if the Merger is not completed
on or before October 31, 2002, provided that the right to terminate this
Agreement pursuant to this Section 9.1(e) shall not be available to any party
where failure to perform any of its obligations under this Agreement results in
the failure of the Merger to be completed by such time.

        The party desiring to terminate this Agreement pursuant to the preceding
paragraphs shall give written notice of such termination to the other party in
accordance with Section 10.5 hereof.


                                       31


        9.2    EFFECT OF TERMINATION AND ABANDONMENT. In the event of
termination of this Agreement and the abandonment of the Merger pursuant to this
Article XI, this Agreement (other than Sections 9.2, 10.1, 10.3, 10.5, 10.6,
10.7, 10.8, 10.10, 10.11, 10.12, 10.14 and 10.15) shall become void and of no
effect with no liability on the part of any party hereto (or of any of its
directors, officers, members, employees, agents, legal or financial advisors or
other representatives); provided, however, that no such termination shall
relieve any party hereto from any liability for any willful breach of this
Agreement prior to termination. If this Agreement is terminated as provided
herein, each party shall use all reasonable best efforts to redeliver all
documents, work papers and other material (including any copies thereof) of any
other party relating to the transactions contemplated hereby, whether obtained
before or after the execution hereof, to the party furnishing the same.

                            ARTICLE X: MISCELLANEOUS

        10.1    CONFIDENTIALITY. (a) Unless (i) otherwise expressly provided in
this Agreement, (ii) required by applicable Law, (iii) necessary to secure any
required Consents as to which the other party has been advised or (iv) consented
to in writing by Microfield and IST, all information (whether oral or written)
and documents furnished in connection herewith together with analyses,
compilations, studies or other documents prepared by such party which contain or
otherwise reflect such information shall be kept strictly confidential by
Microfield, IST, Merger Sub and their respective officers, directors, employees
and agents. Prior to any disclosure permitted pursuant to the preceding
sentence, the party intending to make such disclosure shall consult with the
other party regarding the nature and extent of the disclosure. Nothing contained
herein shall preclude disclosures to the extent necessary to comply with
obligations imposed by applicable Law.

               (b)    In the event the transactions contemplated by this
Agreement are not completed, each party shall return to the other any documents
furnished by the other and all copies thereof that any of them may have made and
will hold in confidence any information obtained from the other party except to
the extent (i) such party is required to disclose such information by Law or
such disclosure is necessary or desirable in connection with the pursuit or
defense of a claim, (ii) such information was known by such party prior to such
disclosure (and provided that, except with respect to information referred to in
the following clause (iii), such party shall have advised the other party of
such knowledge upon or promptly after its receipt of such information) or was
thereafter developed or obtained by such party independent of such disclosure or
(iii) such information is or becomes generally available to the public other
than by breach of this Section 10.1 (or, to such party's Knowledge, breach of a
confidentiality agreement with the other party). Prior to any disclosure of
information pursuant to the exception in clause (i) of the preceding sentence,
the party intending to disclose the same shall so notify the party which
provided the same in order that such party may seek a protective order or other
appropriate remedy should it choose to do so.

        10.2   AMENDMENT AND MODIFICATION. This Agreement may be amended,
modified or supplemented only by a written agreement among IST, Microfield and
Merger Sub.


                                       32


        10.3   WAIVER OF COMPLIANCE; CONSENTS. Any failure of IST on the one
hand, or Microfield and Merger Sub on the other hand, to comply with any
obligation, covenant, agreement or condition herein may be waived by Microfield
on the one hand, or IST on the other hand, only by a written instrument signed
by the party granting such waiver, but such waiver or failure to insist upon
strict compliance with such obligation, covenant, agreement or condition shall
not operate as a waiver of, or estoppel with respect to, any subsequent or other
failure. Whenever this Agreement requires or permits consent by or on behalf of
any party hereto, such consent shall be given in writing in a manner consistent
with the requirements for a waiver of compliance as set forth in this Section
10.3.

        10.4   SURVIVAL. The respective representations, warranties, covenants
and agreements of IST and Microfield contained herein or in any certificates or
other documents delivered prior to or at the Closing shall survive the execution
and delivery of this Agreement, notwithstanding any investigation made or
information obtained by the other party, but shall terminate at the Effective
Time, except for those contained in Article VII and Sections 2.8, 2.9, 2.10,
10.4 and 10.8, which shall survive beyond the Effective Time.

        10.5   NOTICES. All notices and other communications hereunder shall be
in writing and shall be deemed to have been duly given when delivered in person,
by facsimile, receipt confirmed, or on the next business day when sent by

referred to herein including, but not limited to, the attached Exhibits and
Disclosure Schedules, which Exhibits and Disclosure Schedules are incorporated

qualified in their entirety by reference to specific provisions of this
Agreement, and (c) are not intended to constitute and shall not be construed as

               THIS COMMON STOCK PURCHASE AGREEMENT is made as of September 16,
2002, by and among Microfield Graphics, Inc., an Oregon corporation (the
"Company"), and each of the investors listed on Schedule 1 hereto (each an
"Investor" and collectively the "Investors").

               The parties hereby agree as follows:

                      ARTICLE I. PURCHASE AND SALE OF STOCK

               1.2 CLOSING. The purchase and sale of the Purchased Stock shall
take place at the offices of Stoel Rives LLP, 900 SW Fifth Avenue, Suite 2300,

with and into a wholly owned subsidiary of the Company (the "IST Merger"). At
the Closing, the Company shall instruct its transfer agent to deliver to each

                  ARTICLE II. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

               The Company hereby represents and warrants to the investors that:

Company and its officers, directors and shareholders necessary for the

               2.4 VALID ISSUANCE OF COMMON STOCK. The Purchased Stock, when
issued, sold and delivered in accordance with the terms of this Agreement for
the consideration expressed herein, will be duly and validly issued, fully paid,

               2.5 ABSENCE OF CONFLICTING AGREEMENTS; CONSENTS. The execution

any of its properties. No consent, approval, authorization, declaration or other

of this Agreement or its consummation of the transactions contemplated hereby,
except such consents, approvals, authorizations, declarations, registrations or
filings that have already been obtained or made, or those disclosed to the

general economic conditions (a "Material Adverse Effect").

               2.8 LITIGATION. There is no action, proceeding or suit pending,
or, to the Company's knowledge, threatened, that questions the validity of this
Agreement or that would prevent or materially hinder the consummation of the
transactions contemplated hereby or thereby. There is no suit, action or
proceeding pending or, to the knowledge of the Company, threatened against the
Company which, individually or in the aggregate, would reasonably be expected to
have a Material Adverse Effect, nor is there any judgment, decree, injunction,
rule or order of any federal or state governmental authority outstanding against
the Company which, individually or in the aggregate, would reasonably be
expected to have a Material Adverse Effect.

               2.9 SUBSIDIARIES. The Company has no subsidiaries except

          ARTICLE III. REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

               Each investor hereby represents and warrants to the Company that:

               3.1 ORGANIZATION, GOOD STANDING AND QUALIFICATION. If the
Investor is an entity, it is duly organized, validly existing and in good
standing under the laws of its jurisdiction of formation and has all requisite
power and authority, corporate or otherwise, to carry on its business as now
conducted. Investor is duly qualified to transact business and is in good
standing in each jurisdiction in which the failure to so qualify would have a
material adverse effect on its business or properties.

               3.2 AUTHORIZATION. Investor has full power and authority to enter
into this Agreement and this Agreement constitutes his or its valid and legally
binding obligation, enforceable in accordance with its terms, except (i) as
limited by applicable bankruptcy, insolvency, reorganization, moratorium, and
other laws of general application affecting enforcement of creditors' rights
generally and (ii) as limited by laws relating to the availability of specific
performance, injunctive relief, or other equitable remedies.

               3.3 ABSENCE OF CONFLICTING AGREEMENTS; CONSENTS. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby will not conflict in any material respect with or result in
a material breach of any terms or provisions




                                       3


of, or constitute a material default under (a) the Articles of Incorporation,
Bylaws or other organizational or governing documents of Investor; (b) any note,
bond, mortgage, indenture, license, lease, contract, commitment, agreement or
other instrument or obligation to which Investor is a party or by which Investor
or any of its properties may be bound; or (c) any statute, order, writ,
injunction, decree, rule or regulation applicable to Investor or any of its
properties. No consent, approval, authorization, declaration or other order of,
or registration or filing with, any court or regulatory authority or any third
person is required for the valid execution, delivery and performance of this
Agreement by Investor or its consummation of the transactions contemplated
hereby, except such consents, approvals, authorizations, declarations,
registrations or filings that have already been obtained or made, or those
disclosed to the Company pursuant to this Agreement.

               3.4 LITIGATION. There is no action, proceeding or suit pending,
or, to Investor's knowledge, threatened, that questions the validity of this
Agreement or that would prevent or materially hinder the consummation of the
transactions contemplated hereby.

               3.5 PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made
with Investor in reliance upon such Investor's representation to the Company,
which by Investor's execution of this Agreement Investor hereby confirms, that
the Purchased Stock will be acquired for investment for Investor's own account,
not as a nominee or agent, and not with a view to the resale or distribution of
any part thereof, and that Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same. By executing
this Agreement, Investor further represents Investor does not have any contract,
undertaking, agreement or arrangement with any person to sell, transfer or grant
participations to such person or to any third person, with respect to any of the
Purchased Stock.

               3.6 DISCLOSURE OF INFORMATION. Investor believes he or it has
received all the information it considers necessary or appropriate for deciding
whether to purchase the Purchased Stock. Investor further represents that he or
it has had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the offering of the Purchased Stock and
the business, properties and financial condition of the Company. Investor
acknowledges that he or it has reviewed the Merger Agreement relating to the IST
Merger. The foregoing, however, does not limit or modify the representations and
warranties of the Company in Section 3 of this Agreement or the right of
Investor to rely thereon.

               3.7 INVESTMENT EXPERIENCE. Investor is an investor in securities
of companies in the development stage and acknowledges that he or it is able to
fend for himself or itself, can bear the economic risk of his or its investment,
and has such knowledge and experience in financial or business matters that he
or it is capable of evaluating the merits and risks of the investment in the
Purchased Stock.

               3.8 ACCREDITED INVESTOR. Investor is an "accredited investor"
within the meaning of Securities and Exchange Commission ("SEC") Rule 501 of
Regulation D, as presently in effect, in that Investor (a), if a natural person,
(i) has individual net worth, or joint net worth with Investor's spouse, in
excess of $1,000,000 or (ii) has had individual income in excess of $200,000 in
each of the two most recent years or joint income with Investor's spouse in
excess of $300,000 in each of those years and has a reasonable expectation of
reaching the same




                                       4


income level in the current year, or (b) all the equity owners of Investor
satisfy the conditions in clauses (a)(i) or (a)(ii) above if Investor is an
entity.

               3.9 RESTRICTED SECURITIES. Investor understands that the
Purchased Stock he or it is purchasing is characterized as "restricted
securities" under the federal securities laws because it is being acquired from
the Company in a transaction not involving a public offering and that under such
laws and applicable regulations the Purchased Stock may be resold without
registration under the Act only in certain limited circumstances. In this
connection, Investor represents that he or it is familiar with SEC Rule 144, as
presently in effect, and understands the resale limitations imposed thereby and
by the Act.

               3.10 LEGENDS. It is understood that the certificates evidencing
the Purchased Stock may bear the following legend:

               "The securities evidenced by this certificate have not been
               registered under the Securities Act of 1933 (the "Act") or any
               applicable state law, and no interest therein may be sold,
               distributed, assigned, offered, pledged or otherwise transferred
               unless (a) there is an effective registration statement under
               such Act and applicable state securities laws covering any such
               transaction involving these securities or (b) the Company
               receives an opinion of legal counsel for the holder of these
               securities (concurred in by legal counsel for the Company) to the
               effect that such transaction is exempt from registration or the
               Company otherwise satisfies itself that such transaction is
               exempt from registration."

               3.11 NO FINDERS. Investor has not employed any broker, finder,
agent or investment banker, dealt with anyone purporting to act in that capacity
or agreed to pay any brokerage fee, finder's fee or commission with respect to
the transactions contemplated by this Agreement.
