be, duly executed and delivered by Adaptec. This Agreement constitutes, and,
upon Adaptec's execution of each of the other Ancillary Agreements and the

the Adaptec Closing Documents will constitute, a legal, valid and binding
obligation of Adaptec enforceable against Adaptec 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

         SECTION 3.3. No Conflict. The execution, delivery and performance of
this Agreement, the Ancillary Agreements and the Adaptec Closing Documents by
Adaptec and the consummation of the transactions contemplated hereby do not and
will not (a) result in a violation or default in any material respect of any
provision of Adaptec's charter documents or any judgment, order, writ or decree
applicable to Adaptec or to any of the Business Assets or (b) result in the
creation of any material Encumbrance on any of the Business Assets.

         SECTION 3.4. Consents. No consent, approval, order or authorization of
or registration, qualification, designation, declaration or filing with, any
governmental entity on the part of Adaptec is required in connection with the
consummation of the transactions contemplated by this Agreement and the

clear of all material Encumbrances without obtaining the consent or approval of
any person. Schedule 1 was prepared in the ordinary course, in a manner
consistent with Adaptec's past practice and in accordance with Adaptec's
business records.

         SECTION 3.6. No Restrictive Agreements. No Business Asset is bound or
affected by any judgment, injunction, order, decree, contract, covenant or
agreement that restricts or prohibits Adaptec (or would restrict Chaparral) from
freely engaging in the ESS Business as now conducted.

         SECTION 3.7. Litigation. There is no claim, action, suit, arbitration,
mediation, investigation or other proceeding of any nature pending or, to the
best of Adaptec's knowledge, threatened, at law or in equity, by way of
arbitration or before any court, governmental department, commission, board or
agency that: (i) may adversely affect, contest or challenge Adaptec's authority,
right or ability to transfer or convey any of the Business Assets to Chaparral
hereunder or otherwise perform Adaptec's obligations under this Agreement or any

any Business Asset, or any action taken by any employee, consultant or
contractor of Adaptec with respect to any Business Asset, infringes or
misappropriates any Intellectual Property Rights of any third party.

         SECTION 3.8. Intellectual Property Rights.

         (a) Ownership. Adaptec is the sole and exclusive owner or has the right
to use the Business Assets pursuant to license, sublicense, agreement, or other
valid permission, all intellectual property rights necessary for the manufacture
and sale of the Products conducted.

         (b) No Infringement. To Adaptec's knowledge, the Products and, as and
to the extent used in the development of or integrated or incorporated in or
with the Products, the other Licensed Assets have not infringed or violated and
currently do not infringe or violate upon, or misappropriate any copyright, mask
work or trade secret, or any patent or other intellectual property rights (other
than trademarks) of any third party, and no third party has asserted or
threatened to assert against Adaptec any claim of infringement or
misappropriation of any such rights. To Adaptec's knowledge, no third party has
interfered with, infringed upon, misappropriated, or otherwise come into
conflict with any of the Intellectual Property Rights in any manner affecting
the ESS Business.

         (c) Licenses. Adaptec has not granted to any third party any right to
the Business Assets inconsistent with the rights granted to Chaparral hereunder.

         SECTION 3.9. Acquisition for Own Account. The Preferred Shares will be
acquired for investment for Adaptec's own account, not as a nominee or agent,
and not with a view to the public resale or distribution thereof within the
meaning of the 1933 Act, and Adaptec has no present intention of selling,
granting any participation in, or otherwise distributing the same.

         SECTION 3.10. Investment Experience. Adaptec understands that the
acquisition of the Preferred Shares involves substantial risk. Adaptec: (a) has
experience as Adaptec in securities of companies in the development stage and
acknowledges that Adaptec is able to fend for itself, can bear

                                      -7-
<PAGE>   8

the economic risk of Adaptec's investment in the Preferred Shares and warrant
and has such knowledge and experience in financial or business matters that
Adaptec is capable of evaluating the merits and risks of this investment in the
Preferred Shares and protecting its own interests in connection with this
investment and/or (b) has a preexisting personal or business relationship with
Chaparral and certain of its officers, directors or controlling persons of a
nature and duration that enables Adaptec to be aware of the character, business
acumen and financial circumstances of such persons.

         SECTION 3.11. Accredited Adaptec Status. Adaptec is an "accredited
investor" within the meaning of Regulation D promulgated under the 1933 Act.

         SECTION 3.12. Restricted Securities. Adaptec understands that the
Preferred Shares are characterized as "restricted securities" under the 1933 Act
inasmuch as they are being acquired from Chaparral in a transaction not
involving a public offering and that under the 1933 Act and applicable
regulations thereunder such securities may be resold without registration under
the 1933 Act only in certain limited circumstances. In this connection, Adaptec
represents that Adaptec is familiar with Rule 144 of the U.S. Securities and
Exchange Commission (the "SEC"), as presently in effect, and understands the
resale limitations imposed thereby and by the 1933 Act. Adaptec understands that
Chaparral is under no obligation to register any of the securities sold
hereunder except as provided in Investors Rights Agreement. Adaptec understands
that no public market now exists for any of the Preferred Shares and Conversion
Shares (collectively, the "SECURITIES") and that it is uncertain whether a
public market will ever exist for the Securities.

         SECTION 3.13. Further Limitations on Disposition. Without in any way
limiting the representations set forth above, Adaptec further agrees not to make
any disposition of all or any portion of the Securities unless and until:

         (a) there is then in effect a registration statement under the 1933 Act
covering such proposed disposition and such disposition is made in accordance
with such registration statement; or

         (b) Adaptec shall have notified Chaparral of the proposed disposition,
shall have furnished Chaparral with a statement of the circumstances surrounding
the proposed disposition, and, at the expense of Adaptec or its transferee,
shall have furnished Chaparral with an opinion of counsel, reasonably
satisfactory to Chaparral, that such disposition will not require registration
of such securities under the 1933 Act.

         Notwithstanding the provisions of paragraphs (a) and (b) above, no such
registration statement or opinion of counsel shall be required for any transfer
of any Securities in compliance with SEC Rule 144 or Rule 144A.

         SECTION 3.14. Legends. It is understood that the certificates
evidencing the Preferred Shares and Conversion Shares will bear the legends set
forth below:

               (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, As AMENDED (THE

                                      -8-
<PAGE>   9

         "ACT"), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE
         SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE
         AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE ACT
         AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR
         EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
         REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN
         INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE
         AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER
         TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE
         WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

         (b) Any legend required by the laws of the State of California,
including any legend required by the California Department of Corporations and
Sections 417 and 418 if the California Corporations Code or any other state
securities laws, including a legend substantially in the form of the following
on the certificates evidencing the Preferred Shares:

                  THE PREFERRED SHARES EVIDENCED BY THIS CERTIFICATE: (1) ARE
         CONVERTIBLE INTO SHARES OF COMMON STOCK OF CHAPARRAL AT THE OPTION OF
         THE HOLDER AT ANY TIME PRIOR TO AUTOMATIC CONVERSION THEREOF, AND (2)
         AUTOMATICALLY CONVERT INTO COMMON STOCK OF CHAPARRAL IN THE EVENT OF A
         PUBLIC OFFERING MEETING CERTAIN REQUIREMENTS OR UPON CERTAIN CONSENTS
         OF THE HOLDERS OF CHAPARRAL'S PREFERRED STOCK; ALL PURSUANT TO AND UPON
         THE TERMS AND CONDITIONS SPECIFIED IN CHAPARRAL'S CERTIFICATE OF
         INCORPORATION. A COPY OF SUCH CERTIFICATE OF INCORPORATION MAY BE
         OBTAINED, WITHOUT CHARGE, AT CHAPARRAL'S PRINCIPAL OFFICE.

         The legend set forth in (a) above shall be removed by Chaparral from
any certificate evidencing Preferred Shares and Conversion Shares upon delivery
to Chaparral of an opinion by counsel, reasonably satisfactory to Chaparral,
that a registration statement under the 1933 Act is at that time in effect with
respect to the legended security or that such security can be freely transferred
in a public sale without such a registration statement being in effect and that
such transfer will not jeopardize the exemption or exemptions from registration
pursuant to which Chaparral issued the Preferred Shares and Conversion Shares.

         SECTION 3.15. Brokers. Adaptec has not employed any broker, finder,
investment banker or agent, incurred or agreed to pay any brokerage fee,
finder's fee or commission with respect to the transactions contemplated by this
Agreement, or dealt with anyone purporting to act in the capacity of a broker,
finder, investment banker or agent with respect thereto.

business as now conducted and as presently proposed to be conducted, without any
conflict with or infringement of the rights of others. To the best of

<PAGE>   13

relating to any Proprietary Asset of Chaparral, nor is Chaparral bound by or a
party to any option, license or agreement of any kind with respect to any of its

payments to third parties with respect to the marketing, sale, distribution,
manufacture, license or use of any Proprietary Asset or any other property or
rights.

interfere with the use of his or her best efforts to carry out his or her duties
for Chaparral or to promote the interests of Chaparral or that would conflict
with Chaparral's business as proposed to be conducted. The carrying on of
Chaparral's business by the employees and contractors of Chaparral and the
conduct of Chaparral's business as presently proposed, will not, to the best of

A.       Adaptec desires to purchase shares of the Company's Series B Preferred
         Stock, par value $0.001 per share (the "SERIES B PREFERRED STOCK"), in
         exchange for the transfer by Adaptec to the Company of the Business
         Assets, as defined in the Asset Acquisition Agreement between the
         Company and Adaptec entered into concurrently herewith (the "ASSET
         ACQUISITION AGREEMENT").

B.       The Note Holders desire to purchase shares of the Company's Common
         Stock, par value $0.001 per share (the "COMMON STOCK") and/or Series A

         STOCK") in exchange for delivery to the Company by the Note Holders of
         the full purchase price paid by cancellation of indebtedness evidenced
         by promissory notes of the Company in favor of the Note Holders dated
         November 15, 1998 in the aggregate principal amount of $118,750.00 (the
         "PROMISSORY NOTES").

C.       The parties hereto intend that the payment for and receipt of the stock
         of the Company to the Purchasers hereunder and the issuance of the
         Common Stock, Series A Preferred Stock and Series B Preferred Stock by
         the Company hereunder shall be treated as a tax-free exchange, pursuant
         to Section 351 of the Internal Revenue Code of 1986, as amended.
