pursuant to Section 1.6(b)) will be canceled and extinguished and be converted
automatically into the right to receive 0.80 shares of Acquiror Common Stock
(the "Exchange Ratio").

                (b) CANCELLATION OF TARGET COMMON STOCK OWNED BY ACQUIROR OR
TARGET. At the Effective Time, all shares of Target Common Stock that are owned
by Acquiror or any direct or indirect wholly owned subsidiary of Acquiror or of
Target immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof.

                (c) CANCELLATION OF SERIES B PREFERRED STOCK. At the Effective
Time, all shares of Series B Preferred Stock (as defined at Section 2.2) that
are owned by Acquiror, if any, immediately prior to the Effective Time shall be
canceled and extinguished without any conversion thereof.

                (d) TARGET STOCK OPTION PLANS. At the Effective Time, all
outstanding options to purchase Target Common Stock ("Target Options") issued
pursuant to (i) those certain stock option agreements set forth on SECTION
1.6(d) of the Target Disclosure Schedule; and (ii) Target's 1997 Nonstatutory
Stock Option Plan, shall be assumed by Acquiror (the "Assumed Options"). Each
Assumed Option shall continue to have, and be subject to, the same terms and
conditions set forth in Target's 1997 Nonstatutory Stock Option Plan and the
applicable stock option agreements, immediately prior to the Effective Time,
except that (i) such options will be exercisable for that number of whole shares
of Acquiror Common Stock equal to the product of the number of shares of Target
Common Stock that were issuable upon exercise of such option (assuming
acceleration of vesting) multiplied by the Exchange Ratio and, in the case of
fractional shares, such number shall be rounded down to the nearest whole share
of Acquiror Common Stock unless such fractional share is 0.5 of a share or
above, in which case such number shall be rounded up to the nearest whole share
of Acquiror Common Stock, and (ii) the per share exercise price for the shares
of Acquiror Common Stock issuable upon exercise of the Assumed Option will be
equal to the quotient determined by dividing the exercise price per share of
Target Common Stock at which such Assumed Option was exercisable immediately
prior to the Effective Time by the Exchange Ratio, rounded to the nearest whole
cent. Target Options that are not Assumed Options shall terminate upon the
Effective Time in accordance with the terms of the option plans pursuant to
which such options were issued.

                (e) CAPITAL STOCK OF MERGER SUB. At the Effective Time, each
share of Common Stock, no par value, of Merger Sub ("Merger Sub Common Stock")
issued and outstanding immediately prior to the Effective Time shall be
converted into and exchanged for one validly issued, fully paid and
nonassessable share of Common Stock, no par value, of the Surviving Corporation,
and the Surviving Corporation shall be a wholly-owned subsidiary of Acquiror.
Each stock certificate of Merger Sub evidencing ownership of any such shares
shall continue to evidence ownership of such shares of capital stock of the
Surviving Corporation.

                (f) ADJUSTMENTS TO EXCHANGE RATIO. The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split, reverse split, stock
dividend (including any dividend or distribution of securities convertible into
Acquiror Common Stock or Target Common Stock), reorganization, recapitalization
or other like change with respect to Acquiror Common Stock or Target Common
Stock occurring after the date hereof and prior to the Effective Time.

                (g) DISSENTING SHARES. Shares of Target Common Stock held by a
shareholder who has properly exercised dissenters' rights with respect thereto
(collectively, the "Dissenting Shares") in accordance with Section 1300, et seq.
of the California Law (the "Dissenters Law") shall not be converted into
Acquiror Common Stock. A shareholder who has properly exercised such dissenters'
rights shall no longer retain any rights of a shareholder of Target or the
Surviving Corporation, except those provided under the California Law. Target
shall give Acquiror (i) prompt notice of any written demands under the
Dissenters Law with respect to any shares of Target Common Stock, any withdrawal
of any such demands and any other instruments served pursuant to the Dissenters
Law and received by Target, and (ii) the right to participate in all
negotiations and proceedings with respect to any demands under the Dissenters
Law with respect to any shares of Target Common Stock. Target shall cooperate
with Acquiror concerning, and shall not, except with the prior written consent
of Acquiror, voluntarily make any payment with respect to, or offer to settle or
settle, any such demands.

                (h) FRACTIONAL SHARES. No fraction of a share of Acquiror Common
Stock will be issued. The number of shares of Acquiror Common Stock awardable
hereunder (after aggregating all fractional shares of Acquiror Common Stock
resulting from the application of the Exchange Ratio) shall be rounded down to
the nearest whole share of Acquiror Common Stock, unless such fraction is .5 or
more, in which case the number of shares of Acquiror Common Stock awardable
shall be rounded up to the nearest whole share of Acquiror Common Stock.

        1.7 SURRENDER OF CERTIFICATES.

                (a) EXCHANGE AGENT. American Stock Transfer & Trust Company
shall act as exchange agent (the "Exchange Agent") in the Merger.

                (b) ACQUIROR TO PROVIDE COMMON STOCK. Promptly after the
Effective Time, Acquiror shall make available to the Exchange Agent for exchange
in accordance with this Article I, through such reasonable procedures as
Acquiror may adopt, the shares of Acquiror Common Stock issuable pursuant to
Section 1.6(a) in exchange for shares of Target Common Stock outstanding
immediately prior to the Effective Time.

                (c) EXCHANGE PROCEDURES. Promptly after the Effective Time, the
Surviving Corporation shall cause to be mailed to each holder of record of a
certificate or certificates (the "Certificates") which immediately prior to the
Effective Time represented outstanding shares of Target Common Stock, whose
shares were converted into the right to receive shares of Acquiror Common Stock
pursuant to Section 1.6, (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon receipt of the Certificates by the Exchange Agent, and shall be
in such form and have such other provisions as Acquiror may reasonably specify)
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for certificates representing shares of Acquiror Common Stock. Upon
surrender of a Certificate for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Acquiror, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holder of such Certificate shall be entitled to
receive in exchange therefor a certificate representing the number of whole
shares of Acquiror Common Stock which such holder has the right to receive
pursuant to Section 1.6, and the Certificate so surrendered shall forthwith be
canceled. Until so surrendered, each outstanding Certificate that, prior to the
Effective Time, represented shares of Target Common Stock will be deemed from
and after the Effective Time, for all corporate purposes, other than the payment
of dividends, to evidence the ownership of the number of full shares of Acquiror
Common Stock into which such shares of Target Common Stock shall have been so
converted in accordance with Section 1.6.

                (d) DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES. No
dividends or other distributions with respect to Acquiror Common Stock with a
record date after the Effective Time will be paid to the holder of any
unsurrendered Certificate with respect to the shares of Acquiror Common Stock
represented thereby until the holder of record of such Certificate shall
surrender such Certificate. Subject to applicable law, following surrender of
any such Certificate, there shall be paid to the record holder of the
certificates representing whole shares of Acquiror Common Stock issued in
exchange therefor, without interest, at the time of such surrender, the amount
of any such dividends or other distributions with a record date after the
Effective Time theretofore payable (but for the provisions of this Section
1.7(d)) with respect to such shares of Acquiror Common Stock.

   12

                (e) TRANSFERS OF OWNERSHIP. If any certificate for shares of
Acquiror Common Stock is to be issued in a name other than that in which the
Certificate surrendered in exchange therefor is registered, it will be a
condition of the issuance thereof that the Certificate so surrendered will be
properly endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to Acquiror or any agent designated by
it any transfer or other taxes required by reason of the issuance of a
certificate for shares of Acquiror Common Stock in any name other than that of
the registered holder of the Certificate surrendered, or established to the
satisfaction of Acquiror or any agent designated by it that such tax has been
paid or is not payable.

                (f) NO LIABILITY. Notwithstanding anything to the contrary in
this Section 1.7, none of the Exchange Agent, the Surviving Corporation or any
party hereto shall be liable to any person for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat or
similar law.

        1.8 NO FURTHER OWNERSHIP RIGHTS IN TARGET COMMON STOCK. All shares of
Acquiror Common Stock issued upon the surrender for exchange of shares of Target
Common Stock in accordance with the terms hereof shall be deemed to have been
issued in full satisfaction of all rights pertaining to such shares of Target
Common Stock, and there shall be no further registration of transfers on the
records of the Surviving Corporation of shares of Target Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article I.

        1.9 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of
Acquiror Common Stock as may be required pursuant to Section 1.6; provided,
however, that Acquiror may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Acquiror, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

        1.10 TAX CONSEQUENCES. It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code.

        1.11 TAKING OF NECESSARY ACTION; FURTHER ACTION. If, at any time after
the Effective Time, any further action is necessary or desirable to carry out
the purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Target and Merger Sub, the officers and directors of Target
and Merger Sub are fully authorized in the name of their respective corporations
or otherwise to take, and will take, all such lawful and necessary action, so
long as such action is not inconsistent with this Agreement.

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF TARGET

        In this Agreement, any reference to any event, change, condition or
effect being "material" with respect to any person means any material event,
change, condition or effect related to the condition (financial or otherwise),
properties, assets (including intangible assets), liabilities, business,
operations or results of operations of such person and its subsidiaries, taken
as a whole. In this Agreement, any reference to a "Material Adverse Effect" with
respect to any person means any event, change or effect that is materially
adverse to the condition (financial or otherwise), properties, assets,
liabilities, business, operations or results of operations of such person and
its subsidiaries, taken as a whole. In this Agreement, any reference to a
party's "knowledge" means such party's actual knowledge after reasonable inquiry
of officers and directors of such party charged with senior administrative or
operational responsibility for such matters. No representation or warranty is
made by Target with respect to Acquiror in its capacity as a shareholder, or to
its contracts and other relationships with Acquiror. Except as disclosed in that
section of the document of even date herewith delivered by Target to Acquiror
prior to the execution and delivery of this Agreement (the "Target Disclosure
Schedule") corresponding to the Section of this Agreement to which any of the
following representations and warranties specifically relate or as disclosed in
another section of the Target Disclosure Schedule if it is reasonably apparent
on the face of the disclosure that it is applicable to another Section of this
Agreement, Target represents and warrants to Acquiror and Merger Sub as follows:

        2.1 ORGANIZATION, AND QUALIFICATION; NO SUBSIDIARIES. Target is a
corporation duly organized, validly existing and in good standing under the laws
of the state of California and is in good standing as a foreign corporation in
each jurisdiction where the properties owned, leased or operated, or the
business conducted, by it require such qualification, except where failure to be
in good standing or to so qualify would not have a Material Adverse Effect on
Target. Target has the requisite corporate power and authority and all necessary
governmental approvals to own, lease and operate its properties and to carry on
its business as it is now being conducted, except where the failure to have such
power, or authority and governmental approvals would not, individually or in the



                                       -7-

   14

aggregate, have a Material Adverse Effect. Target has heretofore made available
to Acquiror a complete and correct copy of its Restated Articles of
Incorporation (including all Certificates of Determination) and Bylaws, each as
amended to the date hereof (the "Articles of Incorporation" and "Bylaws",
respectively). Such Articles of Incorporation, Bylaws and equivalent
organizational documents are in full force and effect. Target is not in
violation of any provision of its Articles of Incorporation, Bylaws, or
equivalent organizational documents. Target does not have any subsidiaries.

        2.2 CAPITALIZATION. The authorized capital stock of Target consists of
20,000,000 shares of Target Common Stock and 20,000,000 shares of preferred
stock ("Preferred Stock"), 100,000 shares of which are designated Series A
Junior Participating Preferred Stock, no par value ("Junior Preferred Stock")
and 2,000 shares of which are designated Series B Preferred Stock, no par value
(the "Series B Preferred Stock"). As of the close of business on October 21,
1999, 4,305,428 shares of Target Common Stock were issued and outstanding.
Target has no shares of Preferred Stock issued and outstanding. As of the date
hereof, except for (i) 1,494,972 shares of Target Common Stock reserved for
issuance pursuant to outstanding Target Options, (ii) 2,000 shares of Target
Common Stock reserved for issuance pursuant to the potential conversion of the
Series B Preferred Stock, and (iii) 100,000 shares of Junior Preferred Stock
reserved for issuance upon exercise of the Rights, there are not now, and at the
Effective Time there will not be, any existing options, warrants, calls,
subscriptions, or other rights, or other agreements or commitments, obligating
Target to issue, transfer or sell any shares of capital stock of Target or
bonds, debentures, notes or other indebtedness having general voting rights (or
convertible into securities having such rights) of, or other equity interest in,
Target or securities convertible into or exchangeable for such shares or equity
interest or obligating Target to grant, extend or enter into any such option,
warrant, call, subscription or other right, agreement, arrangement or
commitment. Since May 31, 1999, Target has not issued any shares of its capital
stock, except pursuant to Target Options outstanding on such date. All issued
and outstanding shares of Target Common Stock are and all shares of Target
Common Stock which may be issued pursuant to the exercise of outstanding Target
Options will be, when issued in accordance with the respective terms thereof,
duly authorized and validly issued, fully paid and nonassessable, and such
issuance will not violate any preemptive rights under law or otherwise. There
are no outstanding contractual obligations of Target to repurchase, redeem or
otherwise acquire any shares of Target Common Stock or the capital stock of
Target.

        2.3 AUTHORITY RELATIVE TO THIS AGREEMENT.

                (a) Target has the requisite corporate power and authority to
execute and deliver this Agreement and, to the extent required by applicable law
or Target's Articles of Incorporation, subject only to the approval and adoption
of the Merger by the shareholders of Target as contemplated by Section 6.1(a) to



                                       -8-

   15

consummate the transactions contemplated hereby. The execution and delivery of
this Agreement by Target and the consummation by Target of the transactions
contemplated hereby have been duly and validly authorized by all necessary
corporate action on the part of Target, subject, in the case of the Merger, to
the approval thereof by the shareholders of Target. This Agreement has been duly
and validly executed and delivered by Target, and, assuming this Agreement
constitutes a valid and binding obligation of Acquiror and Merger Sub, this
Agreement constitutes a valid and binding agreement of Target, enforceable
against Target in accordance with its terms (except in all cases as such
enforceability may be limited to applicable bankruptcy, insolvency,
reorganization, moratorium, or similar laws affecting the enforcement of
creditor's rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of any court before which any proceeding may be brought).

                (b) Other than in connection with, or in compliance with, the
provisions of California Law with respect to the transactions contemplated
hereby, the federal securities laws, the securities laws of the various states,
the rules of the National Association of Securities Dealers and other than
notices to or filings with the Internal Revenue Service or the Pension Benefit
Guaranty Corporation with respect to employee benefit plans, or under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), no authorization, consent or approval of, or filing with, any
Governmental Entity (as hereinafter defined) is necessary for the consummation
by Target of the transactions contemplated by this Agreement other than
authorizations, consents and approvals the failure to obtain, or filings the
failure to make, which would not, individually or in the aggregate, have a
Material Adverse Effect on Target. As used in this Agreement, the term
"Governmental Entity" means any government or subdivision thereof, domestic,
foreign or supranational or any administrative, governmental or regulatory
authority, agency, commission, tribunal or body, domestic, foreign or
supranational.

        2.4 NO VIOLATION. Neither the execution or delivery of this Agreement by
Target nor the consummation by Target of the transactions contemplated hereby
will (i) constitute a breach or violation of any provision of the Articles of
Incorporation or Bylaws of Target, (ii) constitute a breach, violation or
default (or any event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination of, or accelerate the
performance required by, or result in the creation of any lien or encumbrance
upon any material property or asset of Target under, any note, bond, mortgage,
indenture, deed of trust, license, lease, agreement or other instrument to which
Target, or by which it or any of its properties or assets, are bound, or (iii)
subject to the receipt of the requisite consents, approvals, or authorizations



                                       -9-

   16

of, or filings with Governmental Entities under federal securities laws,
applicable corporate and securities laws, the rules of The Nasdaq Stock Market,
Inc. and the National Association of Securities Dealers, and laws relating to
employee benefit plans, conflict with or violate any order, judgment or decree,
or to the knowledge of Target, any statute, ordinance, rule or regulation
applicable to Target, or by which it or any of its properties or assets may be
bound or affected, other than, in the case of the foregoing clauses (ii) or
(iii), conflicts, breaches, violations, defaults, terminations, accelerations or
creation of liens and encumbrances which, individually or in the aggregate,
would not have a Material Adverse Effect on Target.

        2.5 SEC REPORTS AND FINANCIAL STATEMENTS. Target has filed with the
Securities and Exchange Commission ("SEC"), and has made available to Acquiror,
copies of all forms, reports and documents ("Target SEC Documents") required to
be filed by it since September 1, 1995 under the Securities Act of 1933, as
amended (the "Securities Act") or the Exchange Act of 1934, as amended (the
"Exchange Act"). None of such Target SEC Documents (as of their respective
filing dates) contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they were
made, not misleading (except any statement or omission therein which has been
corrected or otherwise disclosed or updated in a subsequent Target SEC
Document). The audited and unaudited consolidated financial statements of Target
included in any Target SEC Document on Form 10-QSB or Form 10-KSB (the "Target
Financial Statements") have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis (except as otherwise stated
in such financial statements, including the related notes or, in the case of
unaudited statements, as permitted by Form 10-QSB of the SEC rules), comply as
to form in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto and fairly
present the financial position of Target as of the dates thereof and the results
of its operations and changes in financial position for the periods then ended,
subject, in the case of the unaudited financial statements, to year-end audit
adjustments, and except for the absence of certain footnote information in the
unaudited statements. Target does not have any material liabilities or
obligations of any nature (whether absolute, accrued, contingent, unmatured,
unaccrued, unliquidated, unasserted, conditional or otherwise), except for
liabilities or obligations (i) reflected or reserved against on the balance
sheet as at May 31, 1999 (including the notes thereto and the other disclosures
made in Target's Form 10-QSB for the quarter ended May 31, 1999) (the "Target
Balance Sheet") included in the Target SEC Documents, or (ii) incurred in the
ordinary course of business consistent with past practice since such date. The
reserves disclosed in Target SEC Documents as of the Target Balance Sheet Date
and in any subsequently filed Target SEC Documents are sufficient to provide for
Target's warranty obligations.

   17

        2.6 COMPLIANCE WITH APPLICABLE LAWS AND PERMITS; REGULATORY MATTERS. To
the knowledge of Target, it has in effect and holds all permits, licenses,
orders, authorizations, registrations, approvals and other analogous
instruments, and Target has made all filings and registrations and the like
necessary or required by law to conduct its business as presently conducted,
other than such permits, licenses, orders, authorizations, registrations,
approvals, and other instruments, the absence of which do not have a Material
Adverse Effect on Target. Target has not received any written governmental
notices within two years of the date hereof of any violation by Target of any
such laws, rules, regulations or orders. Except as disclosed at Section 2.6 of
the Target Disclosure Schedule or where the failure to comply would not have a
Material Adverse Effect on Target, to the knowledge of Target, Target is not in
default or noncompliance under any (a) permits, consents, or similar
instruments, and (b) the business and local and county laws, ordinances,
regulations, judgments, orders, decrees or rules of any court, arbitrator or
governmental, regulatory or administrative agency or entity, other than such
default or noncompliance which is not reasonably likely to have a Material
Adverse Effect on Target. Without limiting the generality of the foregoing, all
of the products presently marketed by Target have been approved or cleared to
market pursuant to valid and subsisting Premarket Approvals or Section 510(k)
Clearances issued by the United States Food and Drug Administration ("FDA").
Target has never conducted any clinical trials which have required
Investigational Device Exemptions (IDE's). No written notification has been
furnished to Target of any medical complications arising in connection with or
resulting from clinical trials conducted by Target either directly or under its
direction, or from the use of its products following FDA approval or clearance.
Target has not received any written complaint nor has Steven Verdooner, during
the past six months, been made aware of any oral complaint made with respect to
such procedures and no Medical Device Reports have been filed by Target or have
been required to be filed. The design, manufacture and distribution of all of
Target products, to the extent required, has been conducted, and shall continue
through the Effective Date to be conducted, substantially in accordance with
"good manufacturing practices" as required by the FDA.

        2.7 CHANGE OF CONTROL. Except as provided by the terms of any Target
Stock Option Plan, or any Target Options, transactions contemplated by this
Agreement will not constitute a "change of control" under, require the consent
from or the giving of notice to a third party pursuant to, permit a third party
to terminate or accelerate vesting or repurchase rights, or create any other
detriment under the terms, conditions or provisions of any material note, bond,
mortgage, indenture, license, lease, contract, agreement or other instrument or
obligation to which Target is a party or by which it or any of its properties or
assets may be bound, except where the adverse consequences resulting from such
change of control or where the failure to obtain such consents or provide such
notices would not, individually or in the aggregate, reasonably be expect to
have a Material Adverse Effect on Target.



                                      -11-

   18

        2.8 LITIGATION. Except as disclosed in the Target Disclosure Schedule,
in a Target SEC Document or otherwise fully covered by insurance, there is no
suit, claim, action, proceeding or investigation pending or, to the knowledge of
Target, threatened, against Target, individually or in the aggregate, which
would have a Material Adverse Effect on Target or would reasonably be expected
to prevent or materially delay the consummation of the transactions contemplated
by this Agreement. Except as disclosed in the Target SEC Documents filed prior
to the date of this Agreement, Target is not subject to any outstanding order,
writ, injunction or decree which, individually or in the aggregate, would have a
Material Adverse Effect on Target or would reasonably be expected to prevent or
materially delay the consummation of the transactions contemplated hereby.

        2.9 REGISTRATION STATEMENT; PROXY STATEMENT/PROSPECTUS. The information
supplied by Target for inclusion in the registration statement on Form S-4 (or
such other or successor form as shall be appropriate) pursuant to which the
shares of Acquiror Common Stock to be issued in the Merger will be registered
with the SEC (the "Registration Statement") shall not at the time the
Registration Statement (including any amendments or supplements thereto) is
declared effective by the SEC contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The information supplied by Target for inclusion
in the proxy statement/prospectus to be sent to the shareholders of Target in
connection with the meeting of Target's shareholders to consider the Merger (the
"Target Shareholders Meeting") (such proxy statement/prospectus as amended or
supplemented is referred to herein as the "Proxy Statement") shall not, on the
date the Proxy Statement is first mailed to Target's shareholders, at the time
of the Target Shareholders Meeting and at the Effective Time, contain any
statement which, at such time, is false or misleading with respect to any
material fact, or omit to state any material fact necessary in order to make the
statements made therein, in light of the circumstances under which they are
made, not false or misleading; or omit to state any material fact necessary to
correct any statement in any earlier communication with respect to the
solicitation of proxies for the Target Shareholders Meeting which has become
false or misleading. If at any time prior to the Effective Time any event or
information should be discovered by Target which should be set forth in an
amendment to the Registration Statement or a supplement to the Proxy Statement,
Target shall promptly inform Acquiror and Merger Sub. Notwithstanding the
foregoing, Target makes no representation, warranty or covenant with respect to
any information supplied by or respecting Acquiror or Merger Sub (other than
information with respect to Target) which is contained in any of the foregoing
documents.

        2.10 EMPLOYEE BENEFIT PLANS.

                (a) SECTION 2.10(a)/(b) of the Target Disclosure Schedule
includes a complete list of all material employee benefit plans and programs
providing benefits to any employee or former employee of Target sponsored or
maintained by Target or to which Target contributes or is obligated to
contribute ("Plans") and all written employment, severance, consulting and other

Disclosure Schedule, all Plans are in compliance, in all material respects with
all applicable provisions of ERISA, the Code and all laws and regulations
applicable to the Plans. With respect to each Plan that is intended to be a
"qualified plan" within the meaning of Section 401(a) of the Code ("Qualified
Plans"), the IRS has issued a favorable determination letter.

                (d) Except as set forth in SECTION 2.10(d) of the Target
Disclosure Schedule, all contributions required to be made by Target to any Plan
under applicable law or regulation or by any plan document or other contractual
undertaking, and all premiums due or payable with respect to insurance policies
funding any Plan, have been timely made or paid in full or, to the extent not
required to be made or paid, have been fully reflected in the financial
statements of Target included in the Target SEC Documents to the extent required
under generally accepted accounting principles.

                (e) No Plan is subject to Title IV or Section 302 of ERISA or
Section 412 or 4971 of the Code. Without limiting the generality of the
foregoing, no Plan is a "multi-employer plan" within the meaning of Section
4001(a)(3) of ERISA (a "Multi-Employer Plan") or a plan that has two or more
contributing sponsors at least two of whom are not under common control, within
the meaning of Section 4063 of ERISA and which is subject to Title IV of ERISA
(a "Multiple Employer Plan").

(iv) the continuation coverage requirements of Section 601 et seq. of ERISA and
Section 4980B of the Code, or (v) corresponding or similar provisions of foreign
laws or regulations, other than a liability that arises solely out of, or relate

Effective Time. Without limiting the generality of the foregoing, (i) neither of
Target nor any ERISA Affiliate of Target has engaged in any transaction
described in Section 4069 or Section 4204 or 4212 of ERISA, (ii) no liability
under Title IV or a violation of Section 302 of ERISA has been incurred by
Target that has not been satisfied in full, and Target is not aware of any
condition that exists that presents a material risk to Target of incurring any
such liability, other than liability for premiums due to the Pension Benefit
Guaranty Corporation (which premiums have been paid when due) and for
contributions due to a pension plan (for which a contribution has been paid
through the end of 1998), and (iii) no Plan or any trust established thereunder
has incurred any "accumulated funding deficiency" (as defined in Section 302 of
ERISA and Section 412 of the Code), whether or not waived, as of the last day of
the most recent fiscal year of each Plan ended prior to the Effective Date. An
"ERISA Affiliate" means any entity, trade or business that is a member of a
group described in Section 414(b), (c), (m) or (o) of the Code or Section
4001(b)(1) of ERISA that includes Target, or that is a member of the same
"controlled group" as Target, pursuant to Section 4001(a)(14) of ERISA.

                (g) To the knowledge of Target, there are no pending, threatened
or anticipated claims by or on behalf of any Plan, by any employee or
beneficiary covered under any such Plan, or otherwise involving any such Plan
(other than routine claims for benefits).

                (h) With respect to each Plan, Target has complied except to the
extent that such failure to comply would not, individually or in the aggregate,
have a Material Adverse Effect on Target, with (i) the applicable health care
continuation and notice provisions of the Consolidated Omnibus Budget
Reconciliation Act of 1985 ("COBRA") and the regulations (including proposed
regulations) thereunder, (ii) the applicable requirements of the Family Medical
and Leave Act of 1993 and the regulations thereunder, and (iii) the applicable

There are no Tax liens upon any of the assets or property of Target, except
liens for current Taxes not yet due and payable. Target has provided Acquiror
with written schedules with respect to income taxes of (i) the taxable years of
Target as to which the statutes of limitations with respect to Taxes have not
expired and (ii) with respect to such taxable years, those years for which
examinations have been completed, those years for which examinations are
presently being conducted, those years for which examinations have not been

faith by a majority vote that it is necessary to terminate or revise such
amendment or the Rights Agreement in the exercise of its fiduciary obligations

experience in the foreseeable future any difficulty in obtaining, in the desired
quantity and quality and at a reasonable price and upon reasonable terms and
conditions, the raw materials, supplies or component products required for the
manufacture, assembly or production of its products. The values at which
inventories are carried reflect the inventory valuation policy of Target, which
is consistent with its past practice and in accordance with generally accepted
accounting principles applied on a consistent basis. Since the Target Balance
Sheet Date, due provision was made on the books of Target 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
such inventory reserves are adequate to provide for such slow-moving, obsolete
or unusable inventory and inventory shrinkage.

        2.31 ACCOUNTS RECEIVABLE. The accounts receivable disclosed in the
Target SEC Documents as of Target Balance Sheet Date, and, with respect to
accounts receivable created since such date, disclosed in any subsequently filed
Target SEC Documents, or as accrued on the books of Target in the ordinary
course of business consistent with past practices in accordance with generally
accepted accounting principles since the last filed Target SEC Documents,
represent and will represent bona fide claims against debtors for sales and
other charges, are not subject to discount except for normal cash and immaterial
trade discount. The amount carried for doubtful accounts and allowances
disclosed in each of such Target SEC Document or accrued on such books is
sufficient to provide for any losses that may be sustained on realization of the
receivables.

individually accounted for more than 5% of Target's gross revenues during the
12-month period preceding the date hereof has terminated any agreement with
Target. As of the date hereof, no material supplier of Target has indicated that
it will stop, or decrease the rate of, supplying materials, products or services
to Target. Target has not knowingly breached, so as to provide a benefit to
Target that was not intended by the parties, any agreement with, or engaged in

they are capable upon installation of accurately processing, providing and/or
receiving (i) date-related data from, into and between the Twentieth (20th) and
Twenty-First (21st) centuries, or (ii) date-related data in connection with any
valid date in the Twentieth (20th) and Twenty-First (21st) centuries; provided
that all other products used in combination in any way with Target's current
products properly exchange date-related data with them. Target has commenced
efforts to ensure that the information technology systems and non-information
technology systems used by Target in its internal operations will function
properly beyond 1999. Target has made inquiries to its key third-party vendors
and providers as to the status of their Year 2000 efforts, and has not uncovered
any problems that could reasonably be expected to have a material adverse effect
on the operation of the products or that could disrupt or harm the day-to-day
functioning of the business or operations of Target.

State (in proper form and substance for acceptance) setting forth the

shall have entered into an agreement under which Acquiror shall have the right

        4.6 PERFORMANCE OF MANUFACTURING AGREEMENT. Acquiror will continue to
perform its obligations in all material respects under the Manufacturing
Agreement so long as Target is not in material breach thereof.

        4.7 TARGET INDEBTEDNESS TO ACQUIROR.

                (a) Target and Acquiror acknowledge that as of August 31, 1999,
Target owes $1,595,877.41 to Acquiror, subject to a potential reduction by a
$500,000 "break-up" fee which Target asserts is owed by Acquiror to Target in
connection with the termination of the Stock Purchase Agreement between Acquiror
and Target, dated as of February 25, 1998 (the "Deferred Amount"). Target and
Acquiror agree that no payments shall be required to be made in respect of the
Deferred Amount during the term of this Agreement.

                (b) Target and Acquiror agree that Target shall pay to Knobbe,
Martens, Olson & Bear LLP obligations of Target with respect to legal fees in
the approximate amount of $29,500 with respect to services rendered in
connection with patent prosecution work, subject to receipt by Target of
executed copies of a Patent Agreement and a Patent Collateral Agreement from
Acquiror.

                (c) Target and Acquiror agree that, in addition to the amount
specified in Subsection 4.7(a) above, Target owes Acquiror $24,354.43 as of
September 30, 1999 (the "Current Amount"). Target and Acquiror agree that
intercompany accounts (excluding the Deferred Amount) shall be settled on a
monthly basis, commencing October 31, 1999. The Current Amount shall be offset
against any amounts due Target from Acquiror for the month of October. Payment
of the intercompany account shall be made on or before the 15th of each month
for the prior month. Target and Acquiror agree to promptly determine the
intercompany account at the end of each month and to negotiate in good faith
with respect to any differences over the amounts due each other. If the parties,
following good faith negotiations, are unable to resolve disputes over amounts
due, such disputes shall be submitted to arbitration, and the failure to make
payment of disputed amounts shall not be considered a breach of this Agreement
which would give rise to any party having a right to terminate this Agreement.

                (d) Any dispute over the intercompany account, including the
Deferred Amount, which cannot be settled by negotiation between the parties
shall be submitted to and resolved conclusively and finally by binding
arbitration in accordance with the Commercial Arbitration Rules of the American
Arbitration Association, as modified by any agreements that the parties hereto
may execute in connection with the arbitration. The arbitration shall be
conducted by a single neutral arbitrator chosen by mutual agreement between the
parties; provided, however, that if the parties are unable to agree upon a
single arbitrator, then the arbitration shall be conducted by a panel of three
arbitrators. Each party shall choose one arbitrator and the third arbitrator
shall be selected by the two arbitrators so chosen. The fees of the American
Arbitration Association and of the arbitrators shall be borne equally by the
parties. Each party shall bear its own legal fees in connection with any
arbitration.

Surviving Corporation to, indemnify and hold harmless the present and former
officers, directors, employees and agents of Target (the "Indemnified Parties")
in respect of acts or omissions occurring on or prior to the Effective Time to
the extent provided under Target's Articles of Incorporation and Bylaws or any
indemnification agreement with Target officers and directors to which Target is
a party, in each case in effect on the date hereof; provided that such
indemnification shall be subject to any limitation imposed from time to time
under applicable law. Without limitation of the foregoing and in accordance
therewith, in the event any such Indemnified Party is or becomes involved in any
capacity in any action, proceeding or investigation in connection with any
matter relating to this Agreement or the transactions contemplated hereby
occurring on or prior to the Effective Time, Acquiror shall, or shall cause the
Surviving Corporation to, pay as incurred such Indemnified Party's reasonable
legal and other expenses (including the cost of any investigation and
preparation) incurred in connection therewith.



                                      -43-

   50

                (b) For four years after the Effective Time, Acquiror will
continue to use its commercially reasonable efforts to provide officers' and
directors' liability insurance in respect of acts or omissions occurring on or
prior to the Effective Time covering each officer and director of Target
currently covered by Acquiror's officers' and directors' liability insurance
policy on terms substantially similar to those of such policy in effect on the
date hereof. Acquiror confirms that all premiums due on its officers' and
directors' liability insurance policy have been paid to date and that officers
and directors of Target are covered thereunder.

                (c) To the extent there is any claim, action, suit, proceeding
or investigation (whether arising before or after the Effective Time) against an
Indemnified Party that arises out of or pertains to any action or omission in
his or her capacity as director, officer, employee, fiduciary or agent of Target
occurring prior to the Effective Time, or arises out of or pertains to the
transactions contemplated by this Agreement for a period of four years after the
Effective Time (whether arising before or after the Effective Time), in each
case for which such Indemnified Party is indemnified under this Section 5.17,
such Indemnified Party shall be entitled to be represented by counsel, which
counsel shall be counsel of the Acquiror (provided that if use of counsel of the
Acquiror would be expected under applicable standards of professional conduct to
give rise to a conflict between the position of the Indemnified Person and of
the Acquiror, the Indemnified Party shall be entitled instead to be represented
by counsel selected by the Indemnified Party and reasonably acceptable to
Acquiror) and following the Effective Time the Surviving Corporation and
Acquiror shall pay the reasonable fees and expenses of such counsel, promptly
after statements therefor are received and the Surviving Corporation and
Acquiror will cooperate in the defense of any such matter; provided, however,
that neither the Surviving Corporation nor Acquiror shall be liable for any
settlement effected without its written consent (which consent shall not be
unreasonably withheld); and provided, further, that, in the event that any claim
or claims for indemnification are asserted or made within such four year period,
all rights to indemnification in respect to any such claim or claims shall
continue until the disposition of any and all such claims. The Indemnified
Parties as a group may retain only one law firm (in addition to local counsel)
to represent them with respect to any single action unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the position of any two or more Indemnified Parties.

                (d) The provisions of this Section 5.17 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and representatives.

have been approved and adopted by the requisite vote of the shareholders of

for Acquiror included in the Registration Statement shall not contain any

Statement or any part thereof shall have been issued and no proceeding for that
purpose, and no similar proceeding in respect of the Proxy Statement, shall have
been initiated or threatened by the SEC; and all requests for additional
information on the part of the SEC shall have been complied with to the
reasonable satisfaction of the parties hereto.

                (c) NO INJUNCTIONS OR RESTRAINTS; ILLEGALITY. No temporary

governmental authority or instrumentality, domestic or foreign, seeking any of
the foregoing be pending; nor shall there be any action taken, or any statute,

Merger, which makes the consummation of the Merger illegal. In the event an
injunction or other order shall have been issued, each party agrees to use its
reasonable best efforts to have such injunction or other order lifted.

to in the Proxy Statement as first mailed to shareholders of Target and shall be
to the effect that the Merger will constitute a reorganization within the
meaning of Section 368(a) of the Code, and such opinions shall not have been
withdrawn. In rendering such opinion, counsel shall be entitled to rely upon,
among other things, reasonable assumptions as well as representations of
Acquiror, Merger Sub and Target and certain shareholders of Target.

                (f) LISTING OF ADDITIONAL SHARES. The filing with the Nasdaq
National Market of a Notification Form for Listing of Additional Shares with

with evidence satisfactory to it of the consent or approval of those persons
whose consent or approval shall be required in connection with the Merger under
any material contract of Target or otherwise, except where failure to obtain

temporary restraining order, preliminary or permanent injunction or other order
issued by any court of competent jurisdiction or other legal or regulatory

and provided further that the right to terminate this Agreement under this
Section 7.1(b) shall not be available to any party whose action or failure to
act has been the cause of or resulted in the failure of the Merger to occur on

representations, warranties, covenants or other obligations hereunder and such
breach shall not have been cured within ten (10) business days following receipt

Acquiror), Section 5.4 (Confidentiality), Section 7.3 (Expenses and Termination

The table of contents and headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

        8.4 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

        8.5 ENTIRE AGREEMENT; NONASSIGNABILITY; PARTIES IN INTEREST. This
Agreement and the documents and instruments and other agreements specifically
referred to herein or delivered pursuant hereto, including the Exhibits, the
Schedules, including the Target Disclosure Schedule and the Acquiror Disclosure
Schedule (a) constitute the entire agreement among the parties with respect to
the subject matter hereof and supersede all prior agreements and understandings,
both written and oral, among the parties with respect to the subject matter
hereof, except for the Confidentiality Agreement, which shall continue in full
force and effect, and shall survive any termination of this Agreement or the
Closing, in accordance with its terms; (b) are not intended to confer upon any

Agreement will continue in full force and effect and the application of such

        8.7 REMEDIES CUMULATIVE. Except as otherwise provided herein, any and
all remedies herein expressly conferred upon a party will be deemed cumulative
with and not exclusive of any other remedy conferred hereby, or by law or equity

waives and covenants not to assert or plead any objection which they might
otherwise have to such jurisdiction and such process.

document.
