       1.1    PURCHASE AND SALE.   On the Closing Date (as defined in Section 2 
below), Seller agrees to sell, transfer, assign and deliver to Buyer and Buyer 
agrees to purchase, accept and acquire from Seller, all of Seller's right, 
title and interest in and to the assets (the "Assets") of Seller described in 
the Bill of Sale and the Patent Assignment Agreement and the 510(k) Assignment 
Agreement attached as EXHIBITS A, B and C (collectively, the "Conveyance 
Documents").  On the Closing Date, Seller shall deliver executed Conveyance 
Documents to Buyer and shall simultaneously take all additional steps and 
execute all additional documents and instruments as may be necessary to put 
Buyer in possession and complete operating control of the Assets and to 
transfer all Seller's right, title and interest in and to the Assets to Buyer.  
Seller agrees that Buyer shall also have the right to contact and retain 
certain employees, contractors and consultants of Seller including those 
persons whose names are set forth on EXHIBIT D, attached hereto.

       1.2    PURCHASE PRICE.  Upon the terms and subject to the conditions 
contained herein, the purchase price to be paid by Buyer to Seller for the 
sale, transfer, assignment and delivery of the Assets (the "Purchase Price") 
shall be as follows:

       (a)    $4,750,000 in cash at the Closing, subject to Section 1.3.

       (b)    the cancellation of that certain Promissory Note for $375,000

       (c)    $125,000 in cash previously paid to Seller on March 31, 1998 
pursuant to the No-Shop Agreement.

       1.3    CLOSING BALANCE SHEET ADJUSTMENT.

              (a)    Within thirty (30) days after the Closing Date, Seller 
shall cause to be prepared and shall deliver to Buyer a balance sheet of Seller 
as of the close of business on the Closing Date, which balance sheet shall 
reflect, among other things, total Current Assets, total Current Liabilities 
and Net Plant and Equipment ("Closing Date Balance Sheet").  The Closing Date 
Balance Sheet shall be prepared in accordance with GAAP applied in a manner 
consistent with that utilized in preparing the Financial Statements (as defined 
in Section 3.6).

<PAGE>

              (b)    If Buyer does not dispute the amounts set forth in the 
Closing Date Balance Sheet, the Closing Date Balance Sheet shall be conclusive. 
If Buyer disputes any amount set forth in the Closing Date Balance Sheet, 
Buyer shall so notify Seller in writing (specifying his objections and the 
reasons therefor in reasonable detail) within thirty (30) days following 
receipt thereof and the parties will use all reasonable efforts to resolve any 
such disputes.  If any such dispute cannot promptly be resolved (but in any 
event within thirty (30) days after submission of the written objections of 
Buyer, the parties agree that they will submit the matter to the office of 
JAMS/ENdispute located in San Diego, California (or, if none, then the office 
of JAMS/Endispute located closest to San Diego, California) to be arbitrated by 
a single arbitrator to be mutually selected by the parties.  The resolution of 
the dispute by JAMS/Endispute will be conclusive and binding upon the parties.  
The fees and expenses of JAMS/ENdispute will be paid one-half by Seller and 
one-half by Buyer.  The Closing Date Balance Sheet and the information set 
forth thereon, as finally determined pursuant to this Section 1.3(b), is 
hereinafter referred to as the "Final Closing Balance Sheet."

              (c)    In the event the Current Assets and Net Plant and 
Equipment less Current Liabilities set forth in the Final Closing Balance Sheet 
is less than the Current Assets and Net Plant and Equipment less Current 
Liabilities set forth in the December 31, 1997 Balance Sheet contained in 
Schedule 3.6 (the "Assets Shortfall"), then the Seller and Parent, jointly and 
severally, shall be liable to pay over to Buyer an amount in cash equal to the 
Assets Shortfall.

              (d)    Any payment required to be made under Section 1.3(c) shall 
be made within five (5) business days after the determination thereof ("Due 
Date"), without setoff for any other matter, by wire transfer to an account 
designated by Buyer and shall, in addition to such amount, include interest on 
the amount required to be paid calculated from the Closing Date through the Due 
Date at a rate of twelve percent (12%) per annum.  Any payment to be made 
pursuant to Section 1.3(c) which is not made on the Due Date shall bear 
interest at the rate of fifteen percent (15%) per annum from the Due Date until 
the date paid; provided that no interest shall accrue on any payment due under 
Section 1.3(c) for so long as a dispute exists under Section 1.3(b) unless the 
final determination of such dispute requires a payment by the Seller or Parent 
under Section 1.3(c) of more than $50,000.

       1.4    ASSUMED LIABILITIES.  Upon the terms and subject to the 
conditions contained herein, Buyer shall assume all of the current obligations 
and liabilities of Seller set forth on attached EXHIBIT E (the "Assumed 
Liabilities"), which shall set forth the obligations and liabilities being 
assumed as of April 30, 1998.  Buyer shall also assume the liabilities of 
Seller incurred in the ordinary course of Seller's business between April 30, 
1998 and the Closing Date; provided, however, that no liabilities or 
obligations relating to obsolete inventory, or unrecorded or unwritten 
commitments to customers or distributors shall be assumed by Buyer.  Buyer 
shall not assume and shall under no circumstances be responsible for, and 
Seller shall retain and be responsible for, any liabilities or obligations of 
Seller related to the Assets of Seller or Parent whatsoever, regardless of 
amount, character or description, or whether accrued, contingent, determined, 
undetermined, known or unknown or otherwise, including (without limitation) any 
obligation or liability whatsoever arising from the conduct of Seller's 
business or Parent's business at or prior to the Closing Date other than the 
Assumed Liabilities.  Furthermore, and without limiting in any way the 
foregoing, Buyer shall not assume and shall under no circumstances be 
responsible for, and Seller shall retain and be responsible for, any 
liabilities or obligations of Seller related to the employees, consultants and 
contractors of Seller or Parent whatsoever, regardless of amount, character or 
description, or whether accrued, contingent, determined, undetermined, known or 
unknown or otherwise, including (without limitation) any obligation or 
liability whatsoever arising from any employment event or from any employment, 
consulting or contracting agreement related to the periods or entered into 
prior to the Closing.  Without limiting the breadth of the foregoing 
provisions, Seller shall retain and be responsible for, any liabilities or

concerning payment of any salary continuation, any representation by Seller or 
Parent concerning extension of any termination date, any representation by

       1.5    GUARANTY OF PAYMENT OF ACCOUNTS RECEIVABLE AND INTERCOMPANY 
RECEIVABLES. As a material inducement to Buyer's execution of this Agreement, 
and payment of the consideration hereunder, each of Seller and Parent guarantee 
that the accounts receivable as set forth on the 1997 Balance Sheet in Schedule 
3.6 and the Closing Date Balance Sheet (the "Accounts Receivable") will be 
fully and completely paid and discharged as of the date which is seventy-five

balance of all Accounts Receivable as of Receivable Date shall be paid by 
Seller, in the form of a certified or cashier's check, on or before the date 
which is ten (10) business days after the Receivable Date.  Payments received 
from customers by Buyer after the Closing Date shall be applied to such 
customer's Account Receivable on a first in, first out basis (that is, to the

otherwise. Following such payment by Seller, Buyer shall assign all unpaid 
Accounts Receivable to Seller.  Any amounts received as payments on the 
Accounts Receivable by Buyer on or after the Receivable Date shall be held by 
Buyer as custodian for Seller and, further, shall be paid by Buyer to Seller 
within ten (10) business days of the end of each calendar month, commencing 
with the first calendar month ending after the Receivable Date.  Buyer shall 
make a reasonable effort to collect the Accounts Receivable and shall 
cooperate, at Seller's request and expense, in collecting Receivables assigned 
to Seller.

       1.6    ALLOCATION OF PURCHASE PRICE.  The Purchase Price to be paid by 
Buyer to Seller hereunder shall be allocated among the Assets in a manner to be 
mutually agreed upon by the parties.  The parties hereto agree to report this 
transaction for federal and state tax purposes in accordance with such 
allocation of Purchase Price.

       3.2    AUTHORIZATION.  The execution, delivery and performance by Seller 
and Parent of this Agreement, and all documents and instruments contemplated 
hereby, referenced herein or executed in connection herewith (collectively, the 
"Related Documents"), and the consummation by Seller and Parent of the 
transactions contemplated hereby and therein, have been duly authorized and 
approved by all necessary corporate proceedings of Seller and Parent.  This 
Agreement and each of the Related Documents have been duly executed and 
delivered by Seller and Parent and each constitutes a legal, valid and binding 
agreement of Seller and Parent, enforceable against Seller and Parent in 
accordance with their respective terms, except as limited by bankruptcy,

       3.3    TITLE; CONDITION OF ASSETS.  Except as set forth on the 
Disclosure Schedule, Seller has good, marketable and insurable title to all of 
the Assets, free and clear of all mortgages, liens (tax or otherwise), pledges, 
charges, leases, encumbrances, claims or restrictions of any kind or character. 
 The Assets are in good operating condition with no known defects, excepting 
normal wear and tear, and conform with all applicable laws, regulations, 
ordinances and the like.  The Assets constitute all of the material rights and 
properties, tangible or intangible, real or personal, which are used in the 
conduct of the business of Seller, as such business is presently being 
conducted.  No other material properties or rights, whether or not owned by 
Seller, are required for the operation of such business as presently being 
operated.  Seller is in possession and operating control of all of its assets, 
properties and rights related to the conduct of its business.  The Assets are 
not subject to any liability or obligation of whatever nature, whether known or 
unknown, absolute, accrued, contingent or otherwise.

       3.4    NO VIOLATION.  The execution, delivery and performance of this 
Agreement and the Related Documents by Seller and Parent will not (with notice 
and/or the lapse of time) result in a breach or violation of, or constitute a 
material default under, their respective Articles of Incorporation, Code of 
Regulations or any agreement to which Seller or Parent is a party or by which 
Seller or Parent is bound, and will not be in violation of any constitution, 
statute, judgment, order, rule, regulation or other restriction in effect at 
the Closing Date of any court or federal, state or other Governmental Authority 
having jurisdiction over Seller, Parent or the Assets.  Neither Seller or 
Parent is a party to, subject to or bound by any agreement or judgment, order, 
writ, injunction or decree of any court or federal, state or other Governmental 
Authority that prevents or impairs the consummation of the transactions 
contemplated by this Agreement or the Related Documents or the rights of the 
Buyer hereunder and thereunder.

       3.5    GOVERNMENTAL AUTHORITIES.  Except as set forth in the Disclosure 
Schedule, neither Seller nor Parent is required to submit any notice, report or 
other filing to any Governmental Authority nor is any consent, approval or 
authorization of any Governmental Authority required to be obtained in 
connection with the consummation of the transactions contemplated hereby or in 
the Related Documents.

       3.6    FINANCIAL STATEMENTS.   The Disclosure Schedule contains an 
unaudited Balance Sheet of Seller ("Balance Sheet") as at December 31, 1997 and 
at April 30, 1998 (the "Balance Sheet Date"), and a Statement of Income and 
Expense of Seller for the four-month period then ended (the "Income 
Statement"), collectively referred to herein as the "Financial Statements."  
The Balance Sheet fairly and accurately represents the financial position of 
Seller as of the Balance Sheet Date and the Income Statement accurately 
represents the results of the operations of Seller for such periods, each of 
which has been prepared in accordance with GAAP.  Neither Seller, Seller's 
officers, employees or agents or Parent, Parent's officers, employees or agents 
have employed any broker or finder or incurred any liability for any brokerage 
fees, commissions or finders' fees in connection with the transactions 
contemplated hereby or the Related Documents.

       3.7    INVENTORY.  All inventory of Seller reflected on the Balance 
Sheet is (except to the extent of reserves reflected thereon) of a quality and 
quantity usable and salable in the ordinary course of Seller's business as of 
the Balance Sheet Date, and all such inventory is reflected on the Balance 
Sheet with adequate provisions or adjustments for damaged, defective or excess 
inventory, slow-moving inventory and inventory obsolescence and shrinkage at

       3.8    LITIGATION.  Except as set forth in the Disclosure Schedule,

pending or threatened against or affecting any of the Assets or the 
consummation of the transactions contemplated hereby or the Related Documents,

instrumentality has at any time challenged or questioned the legal right of 
Seller to sell any of its products or to provide any of its services in the 
present manner or as contemplated in the conduct of the Seller's business.

       3.9    CONTRACTS.  Seller is not (and, to the best knowledge of Seller 
and Parent no other party is) in breach or default under (with notice and/or 
the lapse of time), and there is no valid basis for a claim of breach or 
default under, any material agreement, instrument, commitment, contract or 
other obligation of any type to which Seller is a party or is bound, or to 
which the Assets are subject, and no event has occurred which constitutes or, 
with the lapse of time and/or the giving of notice, will constitute such a 
breach or default.  The Assets are not subject to any agreement, contract,

whether written or oral and of whatever nature.  A true copy of each agreement, 
contract, commitment or instrument of the type set forth above has been

enforceable in accordance with their respective terms; all parties to such 
Scheduled Contracts have complied with the provisions thereof; no such party is 
in default under any of the terms thereof and no event has occurred that (with 
the passage of time and/or the giving of notice) would constitute a default by 
any party under any provision thereof.  Seller will continue to be entitled to 
the full benefits thereof after the Closing without the consent of or notice to 
any third party and the transactions contemplated hereby and in the Related 
Documents will not create any termination rights in favor of any third party or 
otherwise change the material rights and obligations of the parties thereunder.

business and ownership and use of the Assets, in compliance with all applicable 
foreign, federal, state or local laws, statutes, rules, regulations,

concessions (collectively, "Regulations"), as such apply to the Assets, 
including without limitation, any applicable intellectual property law or other 
Regulations in respect of any of Seller's operations related to its business,

Agreement.

<PAGE>

              (c)    DEFENSE AND SETTLEMENT.  Buyer shall have the right to 
defend a claim of infringement or misappropriation asserted by a third party 
with litigation counsel of its choice and shall instruct said counsel to 
diligently and energetically defend.  Buyer shall keep Seller apprised of the 
developments in the action.  Seller shall cooperate in the defense of each and 
every claim. Without limitation, the cooperation shall include making available 
documents and or witnesses as may be within the control of Seller, cooperating 
in assisting Buyer to determine all particulars of operation of the accused 
product or method, and in identifying and proving counterclaims against the 
third party. Buyer shall retain control of the litigation and shall therefore, 
have the right to make the final decision with respect to defenses, 
counterclaims and strategy. Seller shall strictly observe all conduct and 
communication rules that litigation counsel shall impose with respect to the 
claim or litigation, including, but not limited to, issuance of press releases, 
public statements and even to statements to individuals within the employ of 
Seller who either do not have a strict need to know, or, to whom communication 
would be restricted by reason of any protective order in effect.  Buyer shall 
be entitled to settle any third party claim in any manner which, in Buyer's 
sole judgment, is appropriate, and Seller shall cooperate and comply with such 
acts as shall be required to accomplish settlement.

       7.2  REPRESENTATION, COOPERATION AND SETTLEMENT.

              (a)    Each party agrees to give prompt notice to the other, of 
any claim against the other, which might give rise to a claim based on the 
indemnity contained in Sections 7.1 and 7.2, stating the nature and basis of 
the claim and the amount thereof.

              (b)    In the event any claims, action, suit or proceeding is 
brought against a party (the "Indemnified Party") with respect to which the 
other party (the "Indemnifying Party") may have liability under the indemnity 
contained in Sections 7.1 and 7.2 hereof, the Indemnified Party shall permit 
the Indemnifying Party to assume the defense of any such claim or any 
litigation resulting from such claim, provided that Buyer shall not be required 
to permit Seller or Parent to assume the defense of any third party claim which 
if not first paid, discharged, or otherwise complied with would result in a 
material interruption or cessation of the conduct of Buyer's business or any 
material part thereof or materially impair the value of the Assets.  Failure by 
the Indemnifying Party to notify the Indemnified Party of its election to 
defend any such claim or action by a third party within thirty (30) days after 
notice thereof shall have been given by the Indemnified Party, shall be deemed 
a waiver of any such election. If the Indemnifying Party assumes the defense of 
such claim or litigation resulting therefrom, the obligations of the 
Indemnifying Party hereunder as to such claim shall include taking all steps 
reasonably necessary in the defense or settlement of such claim or litigation 
resulting therefrom, including the retention of competent counsel satisfactory 
to the Indemnified Party, and holding the Indemnified Party harmless from and 
against any and all damage resulting from, arising out of, or incurred with 
respect to any settlement approved by the Indemnifying Party or any judgment in 
connection with such claim or litigation resulting therefrom.  The Indemnifying 
Party shall not, in the defense of such claim or litigation, consent to the 
entry of any judgment (other than a judgment of dismissal on the merits without 
costs) except with the written consent of the Indemnified Party nor enter into 
any settlement (except with the written consent of the Indemnified Party) which 
does not include as an unconditional term thereof the giving by the claimant or 
the plaintiff to the Indemnified Party a release from all liability in respect 
to such claim or litigation.

              (c)    If the Indemnifying Party shall not assume the defense of 
any such claim by a third party or litigation resulting therefrom, the 
Indemnified Party may defend against such claim or litigation in such manner as 
it deems appropriate. The Indemnifying Party shall, in accordance with the 
provisions hereof, promptly reimburse the Indemnified Party for the amount of 
any settlement reasonably entered into by the Indemnified Party and for all 
damage incurred by the Indemnified Party in connection with the defense against 
or settlement of such claim or litigation.

       7.3  INTEREST.  In the case of payments to third parties (including
federal, state, local or other tax authorities) which are indemnifiable
hereunder, the amount of the indemnifying party's liability under this Article 7
with respect thereto shall include interest on the amount of such payment from
the effective date of the indemnified party's notice of such payment to the
indemnifying party or the date on which such payment is made (whichever is
later) through the date on which the indemnified party shall have been
indemnified therefor, at a simple rate of


                                     -17-
<PAGE>

interest equal to eight percent (8%) per annum; provided, in no event shall 
such rate exceed the maximum rate permitted by law.

       7.4    SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  All the 
representations and warranties of the Seller and Parent contained in Article 3 
and of the Buyer in Article 4 above shall survive the Closing hereunder and 
shall continue in full force and effect after such Closing for a period of 
thirty (30) months after the Closing Date; provided, however, that (i) the 
representations and warranties in Sections 3.12, 3.13 and 3.18 shall continue 
to survive after the Closing Date until the expiration of all applicable 
statutes of limitations, and (ii) the representations and warranties in Section 
3.14 shall continue to survive after the Closing Date for a period of five (5) 
years.

       7.5    LIMITATIONS ON INDEMNIFICATION.

              7.5.1  Notwithstanding the other provisions of Section 7 hereof, 
the Buyer agrees that with respect to demands by Buyer for indemnification for 
Claims and Losses relating to breaches of representations or warranties by the 
Seller:

                     (a)  The Seller shall indemnify Buyer only for the amount 
by which the aggregate of all Claims actually suffered exceeds Fifty Thousand 
Dollars ($50,000.00) (this sum being referred to hereafter as the "Deductible").

                     (b)  No demand for indemnification under Section 7 shall 
be made with respect to any Claim that is not for an amount at least equal to 
One Thousand Dollars ($1,000.00) (a "De minimis Claim"), and no De minimis 
Claim shall be taken into account for the purpose of determining whether the 
aggregate Claims exceed the Deductible.

                     (c)  The maximum total liability for all Claims shall be 
the total Purchase Price.

              7.5.2  Notwithstanding the other provisions of Section 7 hereof,
the Buyer agrees that with respect to demands by Buyer for indemnification for
any Claims hereunder against the Seller:

                     (a)  No demand for indemnification under Section 7 shall 
be made with respect to any claim to the extent the Claim arises wholly as a 
result of the passing or amending after the Closing Date of a statute, rule or 
other government regulation with retroactive effect.

                     (b)  The amount of any Claim subject to indemnification 
shall be determined after taking into account the present value of any tax 
benefits (net of tax detriments) accruing to Buyer (or any member of its 
consolidated group) as a result of such Claim, but only to the extent that the 
present value of the tax benefits can be estimated based upon assumptions 
reasonable under the circumstances.

otherwise carry out the transactions contemplated by this Agreement and the 
Related Documents.

       8.2  SALES AND USE TAXES.  Any sales, use or other transfer tax which is

and compliance with the representations, warranties, covenants and conditions 
applicable to Seller and Parent hereunder or the Related Documents.

                                   ARTICLE 9

                            MISCELLANEOUS PROVISIONS

       9.1    INVESTIGATIONS AND SURVIVAL.  The respective representations, 
warranties, covenants and agreements of Seller, Parent and Buyer herein and in 
the Related Documents, or in any certificates or other documents delivered 
prior to or at the Closing, shall not be deemed modified, waived or otherwise 
affected by any investigation made by any party or its representatives hereto.

       9.2    SUCCESSORS AND ASSIGNS.  This Agreement may not be assigned by a

shall not be unreasonably withheld or delayed; provided, however, this 
Agreement may be assigned and the obligations hereunder delegated by the Buyer 
to a purchaser or acquiror of all or substantially all of the business, stock 
or assets of Buyer in whatever form of corporate transaction or to any other 
corporation or entity that, directly or indirectly, through one or more 
intermediaries, controls, is controlled by or under common control with Buyer 
without the consent of Seller or Parent.  Except as otherwise provided herein, 
the terms and conditions of this Agreement shall inure to the benefit of and be 
binding upon the respective successors, assigns, heirs, legatees, executors and 
administrators of the parties.

       9.3    GOVERNING LAW; JURISDICTION AND VENUE; SEVERABILITY.  This 
Agreement shall be governed by and construed in accordance with the laws of the 
State of California, without regard to principles of conflicts of law.  The 
parties agree that any dispute regarding the interpretation or validity of this 
Agreement shall be subject to the exclusive jurisdiction of the state and 
federal courts in and for the County of San Diego, California, and each party 
hereby agrees to submit to the personal and exclusive jurisdiction and venue of 
such courts.  If any term, covenant or condition of this Agreement is held to

hereof and supersede all prior and contemporaneous agreements and 
understandings.  All Exhibits and Schedules attached hereto are incorporated 
herein by this reference.  This Agreement may be modified, amended or

No covenant, term or condition or the breach thereof shall be deemed waived, 
unless it is waived in writing and signed by the party against whom the waiver 
is claimed.  Any waiver of breach of any covenant, term or condition shall not 
be deemed to be a waiver of any preceding or succeeding breach of the same or

strict performance of any covenant, term or condition hereunder shall not 
constitute a waiver of such party's right to demand strict compliance therewith 
in the future.  Time is of the essence for purposes of each and every provision 
of this Agreement.
