Officer of Seller as being prepared in accordance with the definitions herein

relevant principle is not set forth on SCHEDULE 2.7(A), then in accordance with
those generally accepted accounting principles consistently applied with prior
practice for earlier periods (collectively, the "Seller Accounting Principles").
For purposes of preparation of the Closing Statement, all calculations shall be
made with precision, and lack of materiality shall not be a defense to the
requirement of precise and proper determinations. Parent and its auditors or
other representatives shall be provided an opportunity to review the procedures
performed in connection with preparation of the Closing Statement. Immediately
following delivery of the Closing Statement, Seller shall make

                                       11

available, and shall cause its auditors to make available, all records, work
papers and employees at Seller's expense reasonably requested by Parent in
connection with its review of the Closing Statement.

      The Closing Statement, subject to any adjustments agreed to by Parent and
Seller, shall be used for determining any post-Closing adjustments to the
Initial Purchase Price, unless either party provides the other with a notice of
dispute (a "Dispute Notice") within fifteen (15) days of receipt of the Closing
Statement. If a Dispute Notice is given, Parent and Seller shall promptly meet
in good faith to attempt to resolve any issues, and if any issues are unresolved
within fifteen (15) days of the Dispute Notice, the unresolved issues shall be
submitted to a "Big Five" auditing firm with no material existing relationship
to Parent or Seller, which shall be selected by Parent and approved by Seller,
which approval will not be unreasonably withheld or delayed. The independent
auditor shall be directed to issue a final and binding decision as to the
matters in dispute within thirty (30) days of its engagement. The fees and
expenses of the independent auditor shall be divided equally between the
parties.

      The Closing Statement in the form accepted by Parent and Seller, or
determined by the independent auditor, shall be used to adjust the Initial
Purchase Price in the manner set forth in Section 2.7(c) of this Agreement. Any
payments provided for in Section 2.7(c) shall be made within five business days
of the acceptance of the Closing Statement or the independent auditor's
decision. The full force and effect of the representations and warranties
contained herein shall not be diminished by the Closing Statement, the
acceptance thereof by Parent or the decision of the independent auditor.

            (b) DEFINITIONS. "Closing Net Assets Value" shall mean the book
value of the Assets, net of depreciation, amortization, and reserves, as of the
Closing Date.

            (c) PURCHASE PRICE ADJUSTMENT. If the Closing Net Assets Value is
less than the amount shown on SCHEDULE 1.47 delivered at Closing, Seller
(through the Trust) shall pay Parent an amount equal to the difference. If the
Closing Net Assets Value is greater than the amount shown on SCHEDULE 1.47
delivered at Closing, Parent shall pay Seller an amount equal to the difference.

      A payment to Seller shall be made by wire transfer to the Trust Account. A
payment to Parent shall be made by wire transfer to an account designated in
writing by Parent.

      2.8 ALLOCATION. Seller and Parent shall cooperate in the preparation of a
joint schedule (the "Allocation Schedule") allocating the purchase price
(including the Assumed Liabilities) among the Assets. If Seller and Parent are
able to agree upon the Allocation Schedule within 30 days following the Closing
Date, Seller and Parent shall each file IRS Form 8594, and all federal, state,
local and foreign tax returns, in accordance with the Allocation Schedule. If
Parent and Seller are unable to complete the Allocation Schedule within 30 days
following the Closing Date, each of Seller and Parent may file IRS Form 8594 and
any federal, state, local and foreign tax returns, allocating the aggregate
consideration (including the Assumed Liabilities) among the Assets in the manner
each believes appropriate, provided such allocation is reasonable and in
accordance with Section 1060 of the Internal Revenue Code of 1986, as amended,
and the regulations thereunder.

agreements being referred to hereafter as the "Ancillary Agreements") have been,
or upon their execution and delivery hereunder will have been, duly and validly
executed and delivered by Seller and constitute, or will constitute, valid and
binding agreements of Seller enforceable against Seller in accordance with their
respective terms, except as enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting creditors'
rights generally or by general equitable principles or the exercise of judicial
discretion in accordance with such principles. Seller has all requisite power
and authority to execute and deliver this Agreement and, at the time of the
Closing, will have all requisite power and authority to carry out the
transactions contemplated in this Agreement and the Ancillary Agreements to
which it is or will be a party. All requisite corporate action on the part of
Seller has been taken to authorize the execution and delivery of this Agreement
and the Ancillary Agreements to which Seller is or will be a party subject only
to the approval of the Transaction and this Agreement by Seller's stockholders
as contemplated by Section 6.8(a). The affirmative vote of the holders of a
majority of the shares of common stock of Seller outstanding on the record date
for the stockholders meeting called pursuant to Section 6.8(a) (the "Required
Seller Stockholder Vote") is the only vote of the holders of any of Seller's
capital stock necessary under Delaware Law to approve this Agreement and the

                                       13
<PAGE>
transactions contemplated hereby. The Board of Directors of Seller has
unanimously (i) approved this Agreement and the Transaction, (ii) determined
that in its opinion the Transaction and this Agreement is in the best interests
of the stockholders of Seller and is on terms that are fair to such stockholders
and (iii) recommended that the stockholders of Seller approve this Agreement and
the Merger.

      4.4 NO CONFLICTS; CONSENTS. The execution and the delivery of this
Agreement and the Ancillary Agreements to which Seller is or will be a party by
Seller, do not, and the consummation of the transactions contemplated herein and
therein and compliance with the provisions hereof and thereof will not, conflict
with, result in a breach of, constitute a default (with or without notice or
lapse of time, or both) under or violation of, or result in the creation of any
lien, charge or Encumbrance pursuant to, (a) any provision of the Certificate of
Incorporation or Bylaws of Seller, (b) any Law or Decree or (c) any provision of
any agreement, instrument or understanding to which Seller is a party or by
which Seller or any of its properties or assets is bound or affected, nor will
such actions give to any other Person or entity any interests or rights of any
kind, including rights of termination, acceleration or cancellation, in or with
respect to the Business, any of the Assets, the Assumed Liabilities or the
Assumed Contracts. Except as set forth in the immediately preceding sentence, no
consent of any third party or any Governmental Entity is required to be obtained
on the part of Seller to permit the consummation of the transactions
contemplated in this Agreement or the Ancillary Agreements to which Seller is or
will be a party.

      4.5 TITLE TO ASSETS. Seller has good and marketable title to all of the
Assets, free and clear of all Encumbrances except for Permitted Encumbrances. At
the Closing, Seller will sell, convey, assign, transfer and deliver to Parent
and Purchaser good, valid and marketable title, and all Seller's respective
right and interest, in and to all of the Assets, free and clear of any
Encumbrances, except for Permitted Encumbrances. The Assets include all
property, tangible and intangible, and all agreements and rights used in the
Business.

      4.6 TANGIBLE ASSETS. SCHEDULE 1.62 sets forth a complete and accurate list
of the Tangible Assets used in the Business, which description identifies, to
the extent available, original acquisition date and cost of such items. Except
as set forth in SCHEDULE 1.62, each Tangible Asset is, and as of the Closing
Date will be, in good operating condition and good repair, ordinary wear and
tear excepted, will be free from all defect and damage, and are usable in the
ordinary course of business. SCHEDULE 1.62 also sets forth by category the
location of the Tangible Assets as of the Closing Date.

      4.7 INVENTORY. The inventories shown on the Business Financial Statements
or thereafter acquired by Seller were acquired and maintained in the ordinary
course of business, are of good and merchantable quality, and consist of items
of a quantity and quality usable or salable in the ordinary course of business.
Since December 31, 1999, Seller has continued to replenish inventories in a
normal and customary manner consistent with past practices. The values at which
inventories are carried reflect the inventory valuation policy of Seller, which
is consistent with its past practice and in accordance with generally accepted
accounting principles applied on a consistent basis. Since December 31, 1999,
adequate provision has been made on the books of Seller in the ordinary course
of business consistent with past practices to provide for all slow-moving,
obsolete, or unusable inventories to their estimated useful or scrap values and

                                       14
<PAGE>
such inventory reserves are adequate to provide for such slow-moving, obsolete
or unusable inventory and inventory shrinkage. SCHEDULE 1.39 to this Agreement
sets forth by category and amount the location of the Inventory as of the
Closing Date.

      4.8 LITIGATION AND CLAIMS. There are no claims, actions, suits,
proceedings or, to Seller's Knowledge, investigations, pending before any
Governmental Entity, or to Seller's Knowledge, threatened or reasonably
expected, against Seller (a) relating to the Business, the Assets, the Assumed
Liabilities or the Intellectual Property, (b) which questions or challenges the
validity of this Agreement or any of the ANCILLARY Agreements to which either
Seller is or will be a party, or any of the transactions contemplated herein or
therein or (c) which might be reasonably expected to have a Material Adverse
Effect on Seller. Seller is not a party to or subject to any decree, order or
arbitration award (or agreement entered into in any administrative, judicial or
arbitration proceeding with any Governmental Entity) with respect to or
affecting the Business, or any of the Assets, the Assumed Liabilities or the
Intellectual Property.

      4.9 COMPLIANCE WITH LAWS AND REGULATIONS; GOVERNMENTAL LICENSES, ETC.
Seller is in compliance with all applicable Laws or Decrees with respect to or
affecting the Business or the Assets, the Assumed Liabilities or the
Intellectual Property, including, without limitation, Laws or Decrees relating
to anticompetitive or unfair pricing or trade practices, false advertising,
consumer protection, export or import controls, government contracting,
occupational health and safety, equal employment opportunities, fair employment
practices, and sex, race, religious and age discrimination, except for such
failure to comply as which would not result in a Material Adverse Effect on the
Business, the Assets, the Assumed Liabilities or the Intellectual Property.
Seller is not subject to any order, injunction or decree issued by any
Governmental Entity which could impair the ability of Seller to consummate the
transactions contemplated herein or which could adversely affect Purchaser's
conduct of the Business or its use and enjoyment of the Assets or the
Intellectual Property from and after the Closing Date. Seller possesses all
Permits which are required in order for Seller to operate the Business as
presently conducted, and is in compliance with all such Permits. SCHEDULE 4.9 to
this Agreement contains a complete list of such Permits held by Seller relating
to the Business, the date of expiration of each such Permit, and whether each
such Permit is transferable. Neither the sale and transfer of the Assets
pursuant to this Agreement, nor Purchaser's possession and use thereof from and
after the Closing Date because of such sale and transfer will: (a) violate any
law pertaining to bulk sales or transfers or to the effectiveness of bulk sales
or transfers as against creditors of Seller or (b) result in the imposition of
any liability upon Purchaser for appraisal rights or other liability owing to
any shareholder of Seller.

      4.10 FINANCIAL STATEMENTS, SEC REPORTS.

            (a) Seller has delivered to Purchaser copies of (i) Seller's
unaudited balance sheets pertaining to the Business as of December 31, 1999 (the
"Interim Balance Sheet") and statement of operations pertaining to the Business
for the year then ended (collectively, the "Business Financial Statements"). The
Business Financial Statements have been prepared in accordance with GAAP, and
present fairly the financial position of the Business as of their respective
dates and the results of operations and changes in financial position of the
Business for the periods indicated, except that the unaudited Business Financial
Statements do not contain all footnotes and other information required by GAAP.

                                       15
<PAGE>
            (b) There is no debt, liability, or obligation of any nature,
whether accrued, absolute, contingent, or otherwise, and whether due or to
become due, that is not reflected or reserved against in the Business Financial
Statements except for those (i) that have been incurred after December 31, 1999
or (ii) that are not required by GAAP to be included in a balance sheet or the
notes thereto. All debts, liabilities, and obligations incurred by the Business
after December 31, 1999 were incurred in the ordinary course of business. The
Business Financial Statements in accordance with GAAP reflect all costs and
expenses incurred in the operation of the Business.

            (c) Seller has made available to Parent or its counsel through EDGAR
a true and complete copy of each statement, report, registration statement (with
the prospectus in the form filed pursuant to Rule 424(b) of the Securities Act),
definitive proxy statement, and other filing filed with the SEC by Seller since
January 1, 1997, and, prior to the Closing, Seller will have made available to
Parent or its counsel through EDGAR true and complete copies of any additional
documents filed with the SEC by Seller prior to the Closing (collectively, the
"Seller SEC Documents"). In addition, Seller has made available to Parent all
exhibits to the Seller SEC Documents filed prior to the date hereof which are
(i) requested by Parent and (ii) are not available in complete form through
EDGAR ("Requested Confidential Exhibits") and will promptly make available to
Parent all Requested Confidential Exhibits to any additional Seller SEC
Documents filed prior to the Closing. All documents required to be filed as
exhibits to the Parent SEC Documents have been so filed, and all material
contracts so filed as exhibits are in full force and effect, except those which
have expired in accordance with their terms, and neither Seller nor any of its
subsidiaries is in default thereunder. As of their respective filing dates, none
of the Seller SEC Documents contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements made therein, in light of the circumstances in which they
were made, not misleading, except to the extent corrected by a subsequently
filed Seller SEC Document prior to the date hereof. The financial statements of
Seller, including the notes thereto, included in the Seller SEC Documents (the
"Seller Financial Statements"), complied as to form in all material respects
with applicable accounting requirements and with the published rules and
regulations of the SEC with respect thereto as of their respective dates, and
have been prepared in accordance with generally accepted accounting principles
applied on a basis consistent throughout the periods indicated and consistent
with each other (except as may be indicated in the notes thereto or, in the case
of unaudited statements included in Quarterly Reports on Form 10-Qs, as
permitted by Form 10-Q of the SEC). The Seller Financial Statements fairly
present the consolidated financial condition and operating results of Seller and
its subsidiaries at the dates and during the periods indicated therein (subject,
in the case of unaudited statements, to normal, recurring year-end adjustments).
There has been no change in Seller accounting policies except as described in
the notes to the Seller Financial Statements.

      4.11 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since December 31, 1999, Seller
has conducted the Business in the ordinary and usual course consistent with past

                                       17

information, manufacturing and operating specifications, know-how, formulae,
trade secrets, technical data, computer programs, hardware, software and

                  (vi) all other intangible assets, properties and rights
(whether or not appropriate steps have been taken to protect, under applicable
law, such other intangible assets, properties or rights).

            (b) Seller and its subsidiaries own and have good and marketable
title to, or possess legally enforceable rights to use, all Intellectual
Property used or currently proposed to be used in the Business as currently
conducted or as proposed to be conducted by Seller and its subsidiaries. The
Intellectual Property owned by and licensed to Seller collectively constitute
all of the Intellectual Property necessary to enable Seller to conduct the
Business as the Business is currently being conducted. No current or former
officer, director, stockholder, employee, consultant or independent contractor
of Seller has any right, claim or interest in or with respect to any
Intellectual Property used in the Business. There is no unauthorized use,
disclosure or misappropriation of any Intellectual Property used in the Business
by any employee or, to Seller's knowledge, former employee of Seller or any of
its subsidiaries or, to Seller's knowledge, by any other third party. There are
no royalties, fees or other payments payable by Seller to any Person under any
written or oral contract or understanding by reason of the ownership, use, sale
or disposition of Intellectual Property used in the Business.

            (c) With respect to each item of Intellectual Property used in the
Business (except "off the shelf" or other software widely available through
regular commercial distribution channels at a cost not exceeding $10,000 on
standard terms and conditions, as modified for Seller's operations) ("Seller
Intellectual Property") SCHEDULE 4.12 lists all Patents

                                       18
<PAGE>
and Patent Applications and all registered Trademarks, and trademark
applications and all registered Copyrights, including the jurisdictions in which
each such Intellectual Property has been issued or registered or in which any
such application for such issuance and registration has been filed.

            (d) SCHEDULE 4.12 contains an accurate list as of the date of this
Agreement of all licenses, sublicenses and other agreements to which Seller or
its Subsidiaries are a party and pursuant to which Seller or its Subsidiaries
are authorized to use any Intellectual Property owned by any third party,
excluding "off the shelf" or other software at a cost not exceeding $10,000 and
widely available through regular commercial distribution channels on standard
terms and conditions ("Third Party Intellectual Property").

            (e) There is no unauthorized use, disclosure, infringement or
misappropriation of any Seller Intellectual Property, including any Third Party
Intellectual Property by any third party, including any employee or former
employee of Seller or any of its subsidiaries. Neither Seller nor any of its
subsidiaries has entered into any agreement to indemnify any other person
against any charge of infringement of any Intellectual Property. There are no
royalties, fees or other payments payable by Seller to any Person by reason of
the ownership, use, sale or disposition of Intellectual Property.

            (f) Seller is not in breach of any license, sublicense or other
agreement relating to the Seller Intellectual Property or Third Party
Intellectual Property. Neither the execution, delivery or performance of this
Agreement or any ancillary agreement contemplated hereby nor the consummation of
the Acquisition will contravene, conflict with or result in an infringement on
the Parent's right to own or use any Seller Intellectual Property, including any
Third Party Intellectual Property.

            (g) All Patents, registered Trademarks, registered service marks and
registered Copyrights held by Seller are valid and subsisting. All maintenance
and annual fees have been fully paid and all fees paid during prosecution and
after issuance of any patent comprising or relating to such item have been paid
in the correct entity status amounts. Seller is not infringing, misappropriating
or making unlawful use of, or received any notice or other communication (in
writing or otherwise) of any actual, alleged, possible or potential
infringement, misappropriation or unlawful use of any proprietary asset owned or
used by any third party. There is no proceeding pending or threatened to the
knowledge of Seller, nor has any claim or demand been made, which challenges the
legality, validity, enforceability or ownership of any item of Seller
Intellectual Property or Third Party Intellectual Property or alleges a claim of
infringement of any Patents, Trademarks, service marks, Copyrights or violation
of any trade secret or other proprietary right of any third party. Seller has
not brought a proceeding alleging infringement of Seller Intellectual Property
or breach of any license or agreement involving Intellectual Property against
any third party.

            (h) All current and former officers of Seller have executed and
delivered to Seller an agreement (containing no exceptions or exclusions from
the scope of its coverage) regarding the protection of proprietary information
and the assignment to Seller of any Intellectual Property arising from services
performed for Seller by such persons, the form of which has been supplied to
Parent. All current and former consultants and independent

                                       19
<PAGE>
contractors to Seller involved in the development, modification, marketing and
servicing of Seller Intellectual Property have executed and delivered to Seller
an agreement in the form provided to Parent or its counsel (containing no
exceptions or exclusions from the scope of its coverage) regarding the
protection of proprietary information and the assignment to Seller of any
Intellectual Property arising from services performed for Seller by such
persons. It has at all times been Seller's practice and procedure to require all
employees of Seller to execute and deliver to Seller an agreement (containing no
exceptions or exclusions from the scope of its coverage) regarding the
protection of proprietary information and the assignment to Seller of any
Intellectual Property arising from services performed for Seller by such
employees, the form of which has been provided to Parent; and substantially all
of Seller's current and former employees, including all current and former
software engineers, each of which have had access to the Seller's computer
software, have executed such agreements, although some current or former
employees other than those related to software may not have done so. To Seller's
knowledge, no current or former officer, employee or independent contractor of
Seller is in violation of any term of any agreement regarding the protection of
proprietary information and the assignment to Seller of any Intellectual
Property arising from services performed for Seller by such persons or any
employment contract or any other contract or agreement relating to the
relationship of any such officer, employee or independent contractor with
Seller. No current or former officer, director, stockholder, employee,
consultant or independent contractor has any right, claim or interest in or with
respect to any Seller Intellectual Property.

            (i) Seller has taken all commercially reasonable and customary
measures and precautions necessary to protect and maintain the confidentiality
of all Seller Intellectual Property (except such Seller Intellectual Property
whose value would be unimpaired by public disclosure) and otherwise to maintain
and protect the full value of all Intellectual Property it owns or uses. All
use, disclosure or appropriation of Intellectual Property not otherwise
protected by patents, patent applications or copyright ("Confidential
Information") owned by Seller by or to a third party has been pursuant to the
terms of a written agreement between Seller and such third party. All use,
disclosure or appropriation of Confidential Information not owned by Seller has
been pursuant to the terms of a written agreement between Seller and the owner
of such Confidential Information, or is otherwise lawful.

            (j) No product liability claims have been communicated in writing to
or, to Seller's knowledge, threatened against Seller.

            (k) A complete list of Seller's proprietary software ("Seller
Software"), together with a brief description of each, is set forth in SCHEDULE
4.12. Seller Software conforms in all material respects with any specification,
documentation, performance standard, representation or statement provided with
respect thereto by or on behalf of Seller.

            (l) Seller is not subject to any proceeding or outstanding decree,
order, judgment, or stipulation restricting in any manner the use, transfer, or
licensing thereof by Seller, or which may affect the validity, use or
enforceability of such Seller Intellectual Property. Seller is not subject to
any agreement which restricts in any material respect the use, transfer, or
licensing by Seller of the Seller Intellectual Property.

                                       20
<PAGE>
            (m) Seller is not aware that any of Seller's Information Technology
(as defined below) is not Year 2000 Compliant or will cause an interruption in
the ongoing operations of Seller's business on or after January 1, 2000. For
purposes of the foregoing, the term "Information Technology" shall mean and
include all material software, hardware, firmware, telecommunications systems,
network systems, embedded systems and other systems, components and/or services
(other than general utility services including gas, electric, telephone and
postal) that are owned or used by Seller in the conduct of the Business. Seller
has implemented a comprehensive, detailed program to analyze and address the
risk that the computer hardware and software used by them may be unable to
recognize and properly execute date-sensitive functions involving certain dates
prior to and any dates after December 31, 1999 (the "Year 2000 Problem"), and
reasonably believe that such risk will be remedied on a timely basis and will
not have a Material Adverse Effect and Seller believes, after due inquiry, that
each suppler, vendor, customer or financial service organization used or
serviced by Seller has remedied or will remedy on a timely basis the Year 2000
Problem, except to the extent that a failure to remedy by any such suppler,
vendor, customer or financial service organization would not have a Material
Adverse Effect.

      4.13 FACILITIES. SCHEDULE 4.13 provides an accurate and complete list of
the current Facilities. Seller has provided Purchaser true and complete copies
of (i) the leases for any rented Facilities, and (ii) any acquisition
agreements, loan documents, and title reports applicable to any currently owned
Facilities or applicable to any Facilities which Seller has contracted to
acquire in connection with the Business. Seller enjoys peaceful and undisturbed
possession of all current Facilities. Except as set forth on SCHEDULE 4.13,
there exists no event of default by Seller (nor any event which with notice or
lapse of time would constitute an event of default by Seller) with respect to
any agreement or instrument with regard to any current Facility, and to Seller's
Knowledge there exists no event of default by any of the other parties thereto
(nor any event which with notice or lapse of time would constitute an event of
default by any of the other parties thereto) with respect to any such agreement
or instrument, except where such default would not have a Material Adverse
Effect on the Business. Except as set forth on SCHEDULE 4.13, all such
agreements and instruments are in full force and effect.

      4.14 CONTRACTS AND ARRANGEMENTS.

            (a) SCHEDULE 4.14 hereto contains a true and accurate list of all
Contracts, pursuant to which Seller enjoys any right or benefit or undertakes
any obligation related to the Business, the Intellectual Property, the Assumed
Liabilities or the Assets. Except for the Contracts, Seller is not a party to or
otherwise bound by the terms of any contract, agreement or obligation, written
or oral, affecting the Business, the Assets, Intellectual Property, or the
Assumed Liabilities. Each of the Assumed Contracts is (assuming due
authorization and execution by the other party or parties hereto) valid, binding
and in full force and effect and enforceable by Seller in accordance with its
terms, except as enforcement may be limited by general equitable principles and
the exercise of judicial discretion in accordance with such principles. Neither
Seller, nor, to Seller's Knowledge, any other party, is in default under any
Assumed Contract, and there are no existing disputes or claims of default
relating thereto, or any facts or conditions Known to Seller which, if
continued, will result in a default or claim of default thereunder, which
default could reasonably be expected to have a Material Adverse Effect on the
Business, the Assets, the Assumed Contracts or the Assumed Liabilities. No

                                       21
<PAGE>
Assumed Contract contains any liquidated damages, penalty or similar provision.
There is no Assumed Contract which Seller can reasonably foresee will result in
any material loss upon the performance thereof by Purchaser from and after the
Closing Date. To Seller's Knowledge, no party to any Contract has notified
Seller that it intends to cancel, withdraw, modify or amend such Contract.
Except as set forth on SCHEDULE 4.14 attached hereto, no consents are necessary
for the effective assignment to and assumption by Parent or Purchaser of any of
the Assumed Contracts.

            (b) To Seller's Knowledge, there are no unresolved claims between
Seller and any of the principal licensors, vendors, suppliers, distributors,
representatives or customers of the Business, and no event which could
reasonably be expected to result in (i) a material breach of an Assumed
Contract, (ii) a request for a material accommodation or concession in
connection with the sale of services, distributors, representatives or customers
or (iii) a significant impairment of the relationships of any Business with its
principal licensors, vendors, suppliers, distributors, representatives, or
customers, and none of such persons has advised Seller of its intention to cease
doing business with Seller or with Parent or the Purchaser following the Closing
Date, whether as a result of the transactions contemplated hereunder or
otherwise.

            (c) Each accepted and unfilled order entered into by Seller for the
provisions of services by Seller, and each agreement, contract or commitment for
the purchase of supplies, included in the Contracts was made in the ordinary
course of the Business.

      4.15 INSURANCE. Seller maintains insurance policies relating to the
Business providing coverage described on SCHEDULE 4.15. All of such policies are
in full force and effect, and Seller is not in default with respect to any
material provision of any of such policies. Seller has not received notice from
any issuer of any such policies of its intention to cancel, terminate or refuse
to renew any policy issued by it.

      4.16 BROKERS. There is no broker, finder, investment banker or other
person, other than Oak Tree Resources, Inc., whose fees are to be paid by
Seller, who would have any valid claim against any of the parties to this
Agreement for a commission or brokerage fee or payment in connection with this
Agreement or the transactions contemplated herein as a result of any agreement
of, or action taken by, Seller.

      4.17 ACCOUNTS RECEIVABLE. Subject to any reserves set forth in the
Business Financial Statements, the accounts receivable shown on the Business
Financial Statements are valid and genuine, have arisen solely out of bona fide
sales and deliveries of goods, performance of services, and other business
transactions in the ordinary course of business consistent with past practices
in each case with persons other than Affiliates, are not subject to any prior
assignment, lien or security interest and are not subject to valid defenses,
set-offs or counter claims. The accounts receivable will be collected in

such Licenses are current, valid and in good standing, and copies of all such
Licenses have been provided to Purchaser. The Business is conducted and at all
times has been conducted in compliance with Environmental Laws and Licenses,
including without limitation, as may be applicable to the ownership, use,

No civil, criminal or administrative actions, proceedings, directives,
inquiries, or investigations are pending, or to the Knowledge of Seller
threatened, pertaining to Seller or the Business and brought by any Governmental
Entity or Person, regarding any alleged non-compliance by the Business or any
Facility with Environmental Laws, or regarding any alleged Release of Hazardous

affiliate of Seller, or the Business, in connection with the Business or any
Facility, that Hazardous Materials have been Handled improperly or in violation
of Environmental Laws or in such a manner as to harm or threaten to harm human
health, ecology, or the environment. Seller has not received any notice with
respect to any Facility, and is not aware of the issuance, at any time, to any
Person of any notice with respect to any Facility, alleging that (i) a Release
of Hazardous Materials occurred, or is suspected of having occurred, at any time
at a Facility, or (ii) a Facility has been listed or is proposed to be listed on
any list, registry or inventory maintained by any Governmental Entity of sites
where a Release of Hazardous Materials has occurred or is suspected of having
occurred. No Release of Hazardous Materials has occurred at any time in

the Business which require any remedial action, removal action, corrective
action, closure action, or other environmental response action under
Environmental Laws or Licenses. There are not present at any current Facility,
nor to Seller's Knowledge were there present at any prior Facility, nor are
there any plans to install at any current Facility, any aboveground or
underground storage tanks, vaults, containments, impoundments or other
aboveground or underground structures or equipment, that are used, will be used,
or were used, or that are or were intended to be used, for Handling Hazardous
Materials. No equipment or improvements used in the Business presently require,
or to the Knowledge of Seller may require, any expenditure of funds or any
removal, closure, updating, modification or replacement to comply with
Environmental Laws and Licenses. To the Knowledge of Seller, no Release of
Hazardous Materials has migrated to or from, or threatens to migrate to or from,
the soil, surface water, or groundwater of any current Facility. With respect to
the Business and to the Knowledge of Seller, there are no conditions existing at
any site to which Seller has sent Hazardous Materials at any time for
transportation, transfer, recycling, treatment, storage, or disposal, which
require any investigation, remedial action, removal action, corrective action,
or other environmental response action pursuant to Environmental Laws. No
employee of Seller and no other Person currently asserts, has asserted or, to
the Knowledge of Seller threatened or has threatened to assert, a demand or
claim pertaining to Seller, an affiliate of Seller, or the Business, based upon
or relating to alleged damage to health caused by any Hazardous Material
allegedly used in connection with the Business or which was allegedly present at
any Facility.

occurred since the

                                       25
<PAGE>
issuance of each such letter which could reasonably be expected to cause the
loss of the tax-qualified status of any Seller Employee Plan subject to Code
Section 401(a).

            (c) COMPLIANCE (i) Each Seller Employee Plan has been administered
in accordance with its terms and in compliance with the requirements prescribed
by any and all statutes, rules and regulations (including ERISA and the Code),
except as would not have, in the aggregate, a Material Adverse Effect, and
Seller and each subsidiary or ERISA Affiliate have performed all material
obligations required to be performed by them under, are not in material respect
in default under or violation of, and have no knowledge of any material default
or violation by any other party to, any of the Seller Employee Plans; (ii) any
Seller Employee Plan intended to be qualified under Section 401(a) of the Code
has either obtained from the Internal Revenue Service a favorable determination
letter as to its qualified status under the Code, including all amendments to
the Code which are currently effective, or has time remaining to apply under
applicable Treasury Regulations or Internal Revenue Service pronouncements for a
determination or opinion letter and to make any amendments necessary to obtain a
favorable determination or opinion letter; (iii) none of the Seller Employee
Plans promises or provides retiree medical or other retiree welfare benefits to

defined in Section 406 of ERISA or Section 4975 of the Code, with respect to any
Seller Employee Plan; (v) none of Seller, any subsidiary or any ERISA Affiliate
is subject to any liability or penalty under Sections 4976 through 4980 of the
Code or Title I of ERISA with respect to any Seller Employee Plan; (vi) all
contributions required to be made by Seller, any subsidiary or ERISA Affiliate
to any Seller Employee Plan have been paid or accrued; (vii) with respect to
each Seller Employee Plan, no "reportable event" within the meaning of Section
4043 of ERISA (excluding any such event for which the thirty (30) day notice
requirement has been waived under the regulations to Section 4043 of ERISA) nor
any event described in Section 4062, 4063 or 4041 or ERISA has occurred; (viii)
each Seller Employee Plan subject to ERISA has prepared in good faith and timely
filed all requisite governmental reports (which were true and correct as of the
date filed) and has properly and timely filed and distributed or posted all
notices and reports to employees required to be filed, distributed or posted
with respect to each such Seller Employee Plan; (ix) no suit, administrative
proceeding, action or other litigation has been brought, or to the knowledge of
Seller is threatened, against or with respect to any such Seller Employee Plan,
including any audit or inquiry by the IRS or United States Department of Labor;
and (x) there has been no amendment to, written interpretation or announcement
by Seller, any subsidiary or ERISA Affiliate which would materially increase the
expense of maintaining any Seller Employee Plan above the level of expense
incurred with respect to that Plan for the most recent fiscal year included in
Seller's financial statements.

            (d) NO TITLE IV OR MULTIEMPLOYER PLAN None of Seller, any subsidiary
or any ERISA Affiliate has ever maintained, established, sponsored, participated
in, contributed to, or is obligated to contribute to, or otherwise incurred any
obligation or liability (including, without limitation, any contingent
liability) under any "multiemployer plan" (as defined in Section 3(37) of ERISA)
or to any "pension plan" (as defined in Section 3(2) of ERISA) subject to Title
IV of ERISA or Section 412 of the Code. None of Seller, any subsidiary or any
ERISA Affiliate has any actual or potential withdrawal liability (including,
without limitation, any contingent liability) for any complete or partial
withdrawal (as defined in Sections 4203 and 4205 of ERISA) from any
multiemployer plan.

            (e) COBRA, FMLA, HIPAA, CANCER RIGHTS With respect to each Seller
Employee Plan, Seller and each of its United States subsidiaries have complied

or continuation; (ii) the applicable requirements of the Family and Medical
Leave Act of 1993 and the regulations thereunder; (iii) the applicable
requirements of the Health Insurance Portability and Accountability Act of 1996
("HIPAA"); and (iv) the applicable requirements of the Cancer Rights Act of
1998, except to the extent that such failure to comply would not in the
aggregate have a Material Adverse Effect. Seller has no material unsatisfied
obligations to any employees, former employees, or qualified beneficiaries
pursuant to COBRA, HIPAA, or any state law governing health care coverage
extension or continuation.

            (f) EFFECT OF ACQUISITION The consummation of the transactions
contemplated by this Agreement will not (i) entitle any current or former
employee or other service provider of Seller, any subsidiary or any ERISA
Affiliate to severance benefits or any other payment (including, without
limitation, unemployment compensation, golden parachute, bonus or benefits under
any Seller Employee Plan), except as expressly provided in this Agreement or
(ii) accelerate the time of payment or vesting of any such benefits or increase
the amount of compensation due any such employee or service provider. No benefit
payable or which may become payable by Seller pursuant to any Seller Employee
Plan or as a result of or arising under this Agreement shall constitute an
"excess parachute payment" (as defined in Section 280G(b)(1) of the Code) which
is subject to the imposition of an excise Tax under Section 4999 of the Code or
the deduction for which would be disallowed by reason of Section 280G of the
Code. Each Seller Employee Plan can be amended, terminated or otherwise
discontinued after the Closing in accordance with its terms, without material
liability to Parent and/or Purchaser, as the case may be, or Seller (other than
ordinary administration expenses typically incurred in a termination event).

            (g) SALE OF SUBSTANTIALLY ALL ASSETS. Seller agrees that the
consummation of the transactions contemplated by this Agreement constitute, as
provided in Code Section 401(k)(10)(A)(ii), a sale of substantially all the
assets (within the meaning of Code Section 409(d)(2)) used by Seller in any
trade or business.

      4.24 EMPLOYEE MATTERS. Seller is in compliance with all currently
applicable laws and regulations respecting terms and conditions of employment
including, without limitation, applicant and employee background checking,
immigration laws, discrimination laws, verification of employment eligibility,
employee leave laws, classification of workers as employees and independent
contractors, wage and hour laws, and occupational safety and health laws. There
are no proceedings pending or, to Seller's knowledge, reasonably expected or
threatened, between Seller, on the one hand, and any or all of its current or
former employees, on the other hand, including, but not limited to, any claims
for actual or alleged harassment or discrimination based on race, national
origin, age, sex, sexual orientation, religion, disability, or similar tortious
conduct, breach of contract, wrongful termination, defamation, intentional or
negligent infliction of emotional distress, interference with contract or
interference with actual or prospective economic disadvantage. There are no
claims pending, or, to Seller's knowledge, reasonably expected or threatened,
against Seller under any workers' compensation or long term

                                       27
<PAGE>
disability plan or policy. Seller is not a party to any collective bargaining
agreement or other labor union contract, nor does Seller know of any activities
or proceedings of any labor union to organize its employees. Seller has provided
all employees with all wages, benefits, relocation benefits, stock options,
bonuses and incentives, and all other compensation which became due and payable
through the date of this Agreement.

      4.25 INSURANCE. Seller and each of its subsidiaries have policies of
insurance and bonds of the type and in amounts customarily carried by persons
conducting businesses or owning assets similar to those of Seller and its
subsidiaries. There is no material claim pending under any of such policies or
bonds as to which coverage has been questioned, denied or disputed by the
underwriters of such policies or bonds. All premiums due and payable under all
such policies and bonds have been paid and Seller and its subsidiaries are
otherwise in compliance with the terms of such policies and bonds. Seller has no
knowledge of any threatened termination of, or material premium increase with
respect to, any of such policies.

      4.26 COMPLIANCE WITH LAWS. Each of Seller and its subsidiaries has
complied with, is not in violation of and has not received any notices of
violation with respect to, any federal state, local or foreign statute, law or
regulation with respect to the conduct of its business, or the ownership or
operation of its business, except for such violations or failures to comply as
do not and could not be reasonably expected to have a Material Adverse Effect on
Seller.

      4.27 ACCURACY OF MATERIAL FACTS; COPIES OF MATERIALS. No representation,
warranty or covenant of Seller contained in this Agreement or in any
certificate, schedule or exhibit delivered pursuant to this Agreement contains
any untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements contained herein and therein, taken as

applicable. Seller shall not agree to any modification of any Assumed Contract
in the course of obtaining any such consent, where such modification would
materially and adversely affect Parent's or Purchaser's ability to conduct the

                                       31
<PAGE>
permitted by applicable law, in the event consents to the assignment of such
Assumed Contracts are not obtained by Seller as of the Closing, and Parent and
Purchaser agree to close the Acquisition, such Assumed Contracts shall be held,
as and from the Closing Date, by Seller in trust for Parent or Purchaser as
designated by Parent, and the covenants and obligations thereunder shall be
performed by Parent or Purchaser in Seller's respective name and all benefits
and obligations existing thereunder shall be for Parent's or Purchaser's, as
applicable, account PROVIDED that such performance by Parent or Purchaser, as
applicable, shall be contingent on the passing of all benefits of such Assumed
Contracts to Parent and/or Purchaser. Seller shall take or cause to be taken
such actions in its name or otherwise as Parent or Purchaser, as applicable, may
reasonably request so as to provide Parent or Purchaser with the benefits of the
Assumed Contracts and to effect collection of money or other consideration to
become due and payable under the Assumed Contracts, and Seller shall promptly
pay over to Purchaser all money or other consideration received by it in respect
to all Assumed Contracts. The compliance of Seller with this provision shall not
excuse Seller from any breach of the representations, warranties and covenants
of Seller resulting from such non-assignment.

commercial efforts to satisfy or cause to be satisfied all the conditions
precedent to the Closing hereunder, and to cause the transactions contemplated

      12.1 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. (a) The representations
and warranties made by Seller or Purchaser herein, or in any certificate,
schedule or exhibit delivered pursuant hereto, shall in no manner be limited by

representation or warranty of Seller contained in or made pursuant to this
Agreement or any certificate, schedule or exhibit delivered by Seller in
connection with this Agreement;

                  (ii) the breach or nonperformance of any covenant or agreement

liable under this ARTICLE XII shall not exceed $250,000.

            (c) Purchaser's sole and exclusive remedy against Seller for any

(A) nothing contained in this ARTICLE XII shall limit in any manner any remedy
at law or in equity to which Purchaser or any other member of the Purchaser
Group shall be entitled against Seller as a result of willful fraud or
intentional misrepresentation by Seller, or any of its representatives or agents
and (B) the provisions of Sections 12.2(b) above shall not limit, in any manner,

Confidentiality Agreement, and the Ancillary Agreements.

      12.3 ESCROW FUND. At the Closing, $250,000 shall be deposited with, Bank
of America, NT&SA (or other institution selected by Parent with the reasonable
consent of Seller) as escrow agent (the "Escrow Agent"), such deposit to

in the Escrow Agreement attached hereto as EXHIBIT "A". The Escrow Fund shall be
available to compensate Seller pursuant to the indemnification obligations of
the shareholders of Seller.

      12.4 ESCROW PERIOD; RELEASE FROM ESCROW.

            (a) The Escrow Period shall terminate six (6) months after the
Closing (the "Termination Date"); provided, however, that a portion of the
Escrow Fund, which, in the reasonable judgment of Parent, subject to the
objection of Seller and the subsequent arbitration of the matter in the manner
provided in Section 12.7 hereof, is necessary to satisfy any unsatisfied claims
specified in any Officer's Certificate theretofore delivered to the Escrow Agent
prior to termination of the Escrow Period with respect to facts and
circumstances existing prior to expiration of the Escrow Period, shall remain in
the Escrow Fund until such claims have been resolved.

            (b) Within three (3) business days after the Termination Date (the
"Release Date"), the Escrow Agent shall release from escrow to Seller the Escrow
Fund less the dollar amount equal to (A) any portion of the Escrow Fund

indemnification claims by Parent and/or Purchaser (collectively, "Indemnitee")
and (B) any portion of the Escrow Fund subject to delivery to Indemnitee in
accordance with Section 12.4(a) with respect to any pending but unresolved
indemnification claims of Indemnitee. Any portion of the Escrow Fund held as a
result of clause (B) shall be released to Seller or released to Parent (as
appropriate) promptly upon resolution of each specific indemnification claim
involved.

            (c) The Escrow Agent is hereby granted the power to effect any
transfer of the Escrow Fund contemplated by this Agreement.

      12.5 CLAIMS UPON ESCROW FUND. Upon receipt by the Escrow Agent on or
before the Release Date of a certificate signed by any officer of Parent (an
"Officer's Certificate") stating

                                       47
<PAGE>
that with respect to the indemnification obligations of the Seller set forth in
Section 12.2, damages exist and specifying in reasonable detail the individual
items of such damages included in the amount so stated, the date each such item
was paid, or properly accrued or arose, and the nature of the misrepresentation,
breach of warranty, covenant or claim to which such item is related, the Escrow
Agent shall, subject to the provisions of this ARTICLE XII, deliver to Parent
out of the Escrow Fund, as promptly as practicable, cash held in the Escrow Fund
having a value equal to such damages.

      12.6 OBJECTIONS TO CLAIMS.

            (a) At the time of delivery of any Officer's Certificate to the
Escrow Agent, a duplicate copy of such Officer's Certificate shall be delivered
to Seller and for a period of thirty (30) days after such delivery, the Escrow
Agent shall make no delivery of the Escrow Fund hereof unless the Escrow Agent
shall have received written authorization from Seller to make such delivery.
After the expiration of such thirty (30) day period, the Escrow Agent shall make
delivery of the portion of the Escrow Fund or other property in the Escrow Fund
in accordance with Section 12.5 hereof, provided that no such payment or
delivery may be made if Seller shall object in a written statement to the claim
made in the Officer's Certificate, and such statement shall have been delivered
to the Escrow Agent and Parent prior to the expiration of such thirty (30) day
period.

            (b) In case Seller shall so object in writing to any claim or claims
by Parent made in any Officer's Certificate, Parent shall have thirty (30) days
to respond in a written statement to the objection of Seller. If after such
thirty (30) day period there remains a dispute as to any claims, Seller and
Parent shall attempt in good faith for sixty (60) days to agree upon the rights
of the respective parties with respect to each of such claims. If Seller and
Parent should so agree, a memorandum setting forth such agreement shall be
prepared and signed by both parties and shall be furnished to the Escrow Agent.
The Escrow Agent shall be entitled to rely on any such memorandum and shall
distribute the cash from the Escrow Fund in accordance with the terms thereof.

      12.7 RESOLUTION OF CONFLICTS AND ARBITRATION.

            (a) If no agreement can be reached after good faith negotiation
between the parties pursuant to Sections 12.6, either party may, by written
notice to the other, demand arbitration of the matter unless the amount of the
damages is at issue in pending litigation with a third party, in which event
arbitration shall not be commenced until such amount is ascertained or both
parties agree to arbitration; and in either such event the matter shall be
settled by arbitration conducted by one arbitrator. Parent and Seller shall
agree on the arbitrator, provided that if Parent and Seller cannot agree on such
arbitrator, either Parent or Seller can request that Judicial Arbitration and
Mediation Services ("JAMS") select the arbitrator. The arbitrator shall set a
limited time period and establish procedures designed to reduce the cost and
time for discovery while allowing the parties an opportunity, adequate in the
sole judgment of the arbitrator, to discover relevant information from the
opposing parties about the subject matter of the dispute. The arbitrator shall
rule upon motions to compel or limit discovery and shall have the authority to
impose sanctions, including attorneys' fees and costs, to the same extent as a
court of competent law or equity, should the arbitrator determine that discovery
was sought

                                       48
<PAGE>
without substantial justification or that discovery was refused or objected to
without substantial justification. The decision of the arbitrator shall be
written, shall be in accordance with applicable law and with this Agreement, and
shall be supported by written findings of fact and conclusion of law which shall
set forth the basis for the decision of the arbitrator. The decision of the
arbitrator as to the validity and amount of any claim in such Officer's
Certificate shall be binding and conclusive upon the parties to this Agreement,
and notwithstanding anything in ARTICLE XII hereof, the Escrow Agent and the
parties shall be entitled to act in accordance with such decision and the Escrow
Agent shall be entitled to make or withhold payments out of the Escrow Fund in
accordance therewith.

            (b) Judgment upon any award rendered by the arbitrator may be
entered in any court having jurisdiction. Any such arbitration shall be held in
Santa Clara County, California under the commercial rules then in effect of the
American Arbitration Association. For purposes of this Section 12.7(b), in any
arbitration hereunder in which any claim or the amount thereof stated in the
Officer's Certificate is at issue, the party seeking indemnification shall be
deemed to be the Non-Prevailing Party unless the arbitrators award the party
seeking indemnification more than one-half (1/2) of the amount in dispute, plus
any amounts not in dispute; otherwise, the person against whom indemnification
is sought shall be deemed to be the Non-Prevailing Party. The Non-Prevailing
Party to an arbitration shall pay its own expenses, the fees of the arbitrator,
any administrative fee of JAMS, and the expenses, including attorneys' fees and
costs, reasonably incurred by the other party to the arbitration.

      12.8 THIRD-PARTY CLAIMS. In the event Parent becomes aware of a
third-party claim which Parent believes may result in a demand against the
Escrow Fund, Parent shall notify Seller of such claim, and Seller shall be
entitled, at its expense, to participate in any defense of such claim with the
consent of Parent which shall not be unreasonably withheld. Parent shall have
the right in its sole discretion to settle any such claim. In the event that
Seller has consented to any such settlement, Seller shall have no power or
authority to object under ARTICLE XII or any other provision of this Section
12.6 to the amount of any claim by Parent against the Escrow Fund for indemnity
with respect to such settlement.

                                  ARTICLE XIII

                                     GENERAL

      13.1 GOVERNING LAW; JURISDICTION; VENUE. It is the intention of the
parties hereto that the internal laws of the State of California (irrespective
of its choice of law principles) shall govern the validity of this Agreement,
the construction of its terms, and the interpretation and enforcement of the
rights and duties of the parties hereto. Any action to enforce, or which arises
out of or in any way relates to, any of the provisions of this Agreement, or any
of the Ancillary Agreements shall be brought and prosecuted exclusively in the
United States District Court, Northern District of California (or, in the event
such court does not have jurisdiction, the courts of the State of California
located in such district), and the parties hereto hereby consent to the
jurisdiction of such court or courts and to service of process by registered
mail, return receipt requested, or by any other manner provided by the law of
the State of California and the rules of such courts.

      13.2 ASSIGNMENT; BINDING UPON SUCCESSORS AND ASSIGNS. None of the parties
hereto may assign any of its rights or obligations hereunder without the prior
written consent of the other party, which consent shall not be unreasonably
withheld; PROVIDED, HOWEVER, that Parent may assign its rights under this
Agreement (a) to any majority-owned subsidiary of Purchaser, provided that
Parent guarantees the obligations of such subsidiary hereunder or (b) to any
successor of Parent through any merger or consolidation, or purchase of all or
substantially all of Parent's stock or all or substantially all of Parent's
assets. This Agreement will be binding upon and inure to the benefit of the
parties hereto and their respective permitted successors and assigns.

      13.3 SEVERABILITY. If any provision of this Agreement, or the application
thereof, shall for any reason and to any extent be held to be invalid or
unenforceable, the remainder of this Agreement and the application of such
provision to other persons or circumstances shall be interpreted so as best to
reasonably effect the intent of the parties hereto. The parties further agree to
replace such invalid or unenforceable provision of this Agreement with a valid
and enforceable provision which will achieve, to the extent possible, the
economic, business and other purposes of the invalid or unenforceable provision.

      13.4 ENTIRE AGREEMENT. This Agreement, the exhibits and schedules hereto,
the certificates referenced herein, the exhibits thereto, and the
Confidentiality Agreement constitute the entire understanding and agreement of
the parties hereto with respect to the subject matter hereof and thereof and
supersede all prior and contemporaneous agreements or understandings,
inducements or conditions, express or implied, written or oral, between the
parties with respect hereto and thereto including, without limitation, that
certain letter of intent between the parties dated January 19, 2000.

      13.10 CONSTRUCTION AND INTERPRETATION OF AGREEMENT.

            (a) This Agreement has been negotiated by the parties hereto and
their respective attorneys, and the language hereof shall not be construed for
or against either party by reason of its having drafted such language.

            (b) The titles and headings herein are for reference purposes only
and shall not in any manner limit the construction of this Agreement, which
shall be considered as a whole.

            (c) As used in this Agreement, any reference to any state of facts,
event, change or effect being "material" with respect to any entity means a
state of facts that is material to the current condition (financial or
otherwise), properties, assets, liabilities, business or operations of such
entity. Whenever the term "enforceable in accordance with its terms" or like
expression is used in this Agreement, it is understood that excepted therefrom
are any limitations on enforceability under applicable bankruptcy, insolvency,
reorganization, moratorium or other laws of general application affecting the
enforcement of creditor's rights.

      13.11 NO JOINT VENTURE. Nothing contained in this Agreement shall be
deemed or construed as creating a joint venture or partnership between any of
the parties hereto. No party is by virtue of this Agreement authorized as an
agent, employee or legal representative of any other party. No party shall have
the power to control the activities and operations of any other and their status
is, and at all times, will continue to be, that of independent contractors with
respect to each other. No party shall have any power or authority to bind or
commit any other. No party shall hold itself out as having any authority or
relationship in contravention of this Section.

      13.12 ABSENCE OF THIRD PARTY BENEFICIARY RIGHTS. No provisions of this
Agreement are intended, nor shall be interpreted, to provide or create any third
party beneficiary rights or any other rights of any kind in any client,
customer, affiliate, shareholder, partner of any party hereto or any other
person or entity unless specifically provided otherwise herein, and, except as
so provided, all provisions hereof shall be personal solely between the parties
to this Agreement.

      a. On each Offering Date the Company shall grant each Eligible Employee an
option to purchase shares of Common Stock, subject to the limitations set forth
in Sections 3.b, 3.c and 10 hereof.

      b. The option price per share of the Common Stock subject to an offering

of a share of Common Stock on the Offering Date or (ii) eighty-five percent
(85%) of the Fair Market Value of a share of Common Stock on the Exercise Date.

purchase Common Stock under all employee stock purchase plans of the Company to
accrue at a rate which exceeds $25,000 of the Fair Market Value of the Common
Stock (determined at the time the option is granted) for each calendar year in
which such stock option is outstanding at any time.

      d. No Participant may be granted an option if, upon such grant, such
Participant would own immediately after the grant of an option under the Plan
and applying the rules of Section 424(d) of the Code in determining stock
ownership shares, and/or hold outstanding options to purchase shares, possessing
five percent (5%) or more of the total combined voting power or value of all
classes of shares of the Company.

      5. PAYROLL DEDUCTIONS AND LUMP SUM PAYMENTS.

      a. An Eligible Employee may become a Participant in the Plan through
payroll deduction on an Offering Date by delivering an Authorization Form to the
Company within the time specified in rules adopted by the Committee. Each such
Authorization Form shall authorize payroll deductions of up to the maximum
amount or percentage of Compensation specified by the Committee (if any such
maximum amount or percentage of Compensation is lower than the amount
established by operation of section 4(c) hereof) of such Employee's Compensation
during the Offering. Payroll deductions shall not be less than five dollars for
Employees paid on a weekly basis nor less than ten dollars for Employees paid on
a bi-weekly basis. A Participant may increase or decrease such payroll deduction
(including a cessation of payroll deductions) effective as of the start of the
next Offering Period, provided the Participant files with the Company the
Authorization Form requesting such change by the date required by the Company.
An Eligible Employee may also become a Participant for an Offering Period by
making one lump sum payment into his or her account if lump sum payments are not
specifically prohibited by the Committee for such Offering Period. Such a
lump-sum amount shall be due by the date prescribed by the Committee and shall
not exceed any maximum amount established by the Committee. Participants who
have enrolled through an Authorization Form may also make one lump sum payment
per Offering Period by the date prescribed by the Committee as long as they have
not already reached the maximum amount permitted for such Offering Period.

      b. All payroll deductions and lump-sum payments (if any) made by a
Participant shall be credited to such Participant's account under the Plan.

      6. EXERCISE OF OPTION.

      a. Unless a Participant withdraws from the Plan as provided in Section 8
hereof, such Participant's election to purchase shares will be exercised
automatically on the Exercise Date, and the maximum number of full shares
subject to such option will be purchased for such Participant at the applicable
option price with the accumulated payroll deductions, cash dividends (credited
pursuant to Section 9 hereof) and lump-sum payment amount in such Participant's
account. During a Participant's lifetime, his or her option to purchase shares
hereunder is exercisable only by such Participant.

      b. Any cash balance remaining in a Participant's account after the
termination of an Offering Period will be carried forward to the Participant's
account for the purchase of Common Stock during the next Offering Period if the
Participant has elected to continue to participate in the Plan. Otherwise the
Participant will receive a cash payment equal to the balance of his or her
account as soon as administratively
<PAGE>
feasible.

      c. The shares of Common Stock purchased upon exercise of an option
hereunder shall be credited to the Participant's account under the Plan and
shall be deemed to be transferred to the Participant on the Exercise Date and,
except as otherwise provided herein, the Participant shall have all rights of a
stockholder with respect to such shares.

      7. DELIVERY OF COMMON STOCK. As promptly as practicable after receipt by
the Committee of a written request for withdrawal of Common Stock from any
Participant, the Company shall arrange the delivery to such Participant of a
stock certificate representing the shares of Common Stock which the Participant
requests to withdraw. Withdrawals may be made no more frequently than once each
Plan Year unless approved by the Committee in its sole discretion. Shares of
Common Stock received upon stock dividends or stock splits shall be treated as
having been purchased on the Exercise Date of the shares to which they relate.

      8. WITHDRAWAL; TERMINATION OF EMPLOYMENT.

      a. A Participant may withdraw all, but not less than all, the payroll
deductions, cash dividends and lump-sum payment amount credited to such
Participant's account (that have not been used to purchase shares of Common
Stock) under the Plan at any time by giving written notice to the Company
received prior to the Exercise Date. All such amounts credited to such
Participant's account will be paid to such Participant promptly after receipt of
such Participant's notice of withdrawal and such Participant's option for the
Offering Period in which the withdrawal occurs will be automatically terminated.
No further payroll deductions for the purchase of shares of Common Stock will be
made for such Participant during such Offering Period, any additional cash
dividends during the Offering Period will be distributed to the Participant, and
no further lump-sum payments for such Offering Period will be accepted. If a
Participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the Participant
delivers to the Company a new Authorization Form.

      b. A Participant's withdrawal from an Offering Period will not have any
effect upon such Participant's eligibility to participate in a succeeding
Offering Period or in any similar plan, which may hereafter be adopted by the
Company.

      c. Upon termination of a Participant's status as an Employee during the
Offering Period for any reason, including voluntary or involuntary termination,
retirement or death, the payroll deductions, cash dividends and any lump-sum
payment credited to such Participant's account that have not been used to
purchase shares of Common Stock will be returned (and any future cash dividends
will be distributed) to such Participant or, in the case of such Participant's
death, to the person or persons entitled thereto under Section 12 hereof, and
such Participant's option will be automatically terminated. A Participant's
status as an Employee shall not be considered terminated in the case of a leave
of absence agreed to in writing by the Company (including, but not limited to,
military and sick leave), provided that such leave is for a period of not more
than ninety (90) days or reemployment upon expiration of such leave is
guaranteed by contract or statute.

      9. DIVIDENDS.

      a. Cash dividends paid on Common Stock held in a Participant's account
shall be credited to such Participant's account and used in addition to payroll
deductions and lump-sum payments to purchase shares of Common Stock on the
Exercise Date. Dividends paid in Common Stock or stock splits of the Common
Stock shall be credited to the accounts of Participants. Dividends paid in
property other than cash or Common Stock shall be distributed to Participants as
soon as practicable.

      b. No interest shall accrue on or be payable with respect to the payroll
deductions or credited cash dividends of a Participant in the Plan.
<PAGE>
      10. STOCK.

      a. The maximum number of shares of Common Stock, which shall be reserved
for sale under the Plan, shall be 250,000, subject to adjustment upon the
occurrence of an event as provided in Section 15 hereof. If the total number of
shares which would otherwise be subject to options granted pursuant to Section
4.a. hereof on an Offering Date exceeds the number of shares then available
under the Plan (after deduction of all shares for which options have been
exercised or are then outstanding), the Committee shall make a pro rata
allocation of the shares remaining available for option grant in as uniform a
manner as shall be practicable and as it shall determine to be equitable. In
such event, the Committee shall give written notice to each Participant of such
reduction of the number of option shares affected thereby and shall similarly
reduce the rate of payroll deductions, if necessary. The source of shares may be
treasury, open market purchase, or new issue.

      b. Shares of Common Stock to be delivered to a Participant under the Plan
will be registered in the name of the Participant or, at the election of the
Participant, in the name of the Participant and another person as joint tenants
with rights of survivorship.

      11. ADMINISTRATION. The Plan shall be administered by the Committee, and
the Committee may select an administrator to whom its duties and
responsibilities hereunder may be delegated. The Committee shall have full power
and authority, subject to the provisions of the Plan, to promulgate such rules
and regulations as it deems necessary for the proper administration of the Plan,
to interpret the provisions and supervise the administration of the Plan, and to
take all action in connection therewith or in relation thereto as it deems
necessary or advisable. Any decision reduced to writing and signed by a majority
of the members of the Committee shall be fully effective as if it had been made
at a meeting duly held. The Company will pay all expenses incurred in the
administration of the Plan. No member of the Committee shall be personally
liable for any action, determination, or interpretation made in good faith with
respect to the Plan, and all members of the Committee shall be fully indemnified
by the Company with respect to any such action, determination or interpretation.

      12. DESIGNATION OF BENEFICIARY.

      a. A Participant may file, on forms supplied by and delivered to the
Company, a written designation of a beneficiary who is to receive any shares and
cash in the event of the Participant's death.

      b. Such designation of beneficiary may be changed by the Participant at
any time by written notice. In the event of the death of a Participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such Participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the Participant
or, if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
Participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

      13. TRANSFERABILITY. Neither amounts credited to a Participant's account
nor any rights with regard to the exercise of an option or to receive shares
under the Plan may be assigned, transferred, pledged or otherwise disposed of in
any way (other than by will, the laws of descent and distribution or as provided
in Section 12 hereof) by the Participant. Any such attempt at assignment,
transfer, pledge or other disposition shall be without effect, except that the
Company may treat such act as an election to withdraw funds in accordance with
Section 8 hereof.

      14. USE OF FUNDS. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.
<PAGE>
      15. EFFECT OF CERTAIN CHANGES. In the event of any increase, reduction, or
change or exchange of shares of Common Stock for a different number or kind of
shares or other securities of the Company by reason of a reclassification,
recapitalization, merger, consolidation, reorganization, stock dividend, stock
split or reverse stock split, combination or exchange of shares, repurchase of
shares, change in corporate structure, distribution of an extraordinary dividend
or otherwise, the Committee shall conclusively determine the appropriate
equitable adjustments, if any, to be made under the Plan, including without
limitation adjustments to the number of shares of Common Stock which have been
authorized for issuance under the Plan but have not yet been placed under
option, as well as the price per share of Common Stock covered by each option
under the Plan which has not yet been exercised.

      16. AMENDMENT OR TERMINATION. The Board may at any time terminate or amend
the Plan. Except as provided in Section 15 hereof, no such termination can
adversely affect options previously granted and no amendment may make any change
in any option theretofore granted which adversely affects the rights of any
Participant. No amendment shall be effective unless approved by the stockholders
of the Company if stockholder approval of such amendment is required to comply
with any law, regulation or stock exchange rule.

      17. NOTICES. All notices or other communications by a Participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

      18. REGULATIONS AND OTHER APPROVALS; GOVERNING LAW.

      a. This Plan and the rights of all persons claiming hereunder shall be
construed and determined in accordance with the laws of the State of Texas
applicable to contracts made and to be performed in such State.

      b. The obligation of the Company to sell or deliver shares of Common Stock
with respect to options granted under the Plan shall be subject to all
applicable laws, rules and regulations, including all applicable Federal and
state securities laws, and the obtaining of all such approvals by governmental
agencies as may be deemed necessary or appropriate by the Committee.

      c. The Plan is intended to comply with Rule 16b-3 as promulgated under
Section 16 of the Exchange Act and the Committee shall interpret and administer
the provisions of the Plan in a manner consistent therewith. Any provisions
inconsistent with such Rule shall be inoperative and shall not affect the
validity of the Plan.

      19. WITHHOLDING OF TAXES. If the Participant makes a disposition, within
the meaning of Section 424(c) of the Code and regulations promulgated
thereunder, of any share or shares issued to such Participant pursuant to such
Participant's exercise of an option, and such disposition occurs within the
two-year period commencing on the day after the Offering Date or within the
one-year period commencing on the day after the Exercise Date, such Participant
shall, within five (5) days of such disposition, notify the Company thereof and
thereafter immediately deliver to the Company any amount of Federal, state or
local income taxes and other amounts which the Company informs the Participant
the Company is required to withhold.

      20. EFFECTIVE DATE; APPROVAL OF STOCKHOLDERS. The Plan is effective as of
January 1, 2000. The Plan shall be submitted to the stockholders of the Company
for their approval within twelve (12) months after the date the Plan is adopted.
The Plan is conditioned upon the approval of the stockholders of the Company,
and failure to receive their approval shall render the Plan and all outstanding
options issued thereunder void and of no effect.
