material adverse effect on the value of the Wilshire Med Assets.

         4.4   Contracts and Leases. Except for the Assumed Contracts, Wilshire
Tech is not a party to any written or oral leases, commitments, or any other
agreements in respect of the operations of Wilshire Med. Each of the Assumed
Contracts is a valid and binding obligation of Wilshire Tech and the other
parties thereto, enforceable in accordance with its terms, except as may be
affected by bankruptcy, insolvency, moratorium, or similar laws affecting
creditors' rights generally and general principles of equity relating to the
availability of equitable remedies. There have not been any defaults by Wilshire
Tech or, to the best of Wilshire Tech's knowledge, defaults or any claims of
default or claims of unenforceability by the other party or parties which,
individually or in the aggregate, would have a material adverse effect on the
Business or any of the Wilshire Med Assets, and, to the best of Wilshire Tech's
knowledge, there are no facts or conditions that have occurred or that are
anticipated to occur which, through the passage of time or the giving of notice,
or both, would constitute a default by Wilshire Tech in respect of the Business,
or by the other party or parties, under any of such contracts, agreements,
leases, licenses, and instruments or would cause a creation of a lien, security
interest, or encumbrance upon any of the Wilshire Med Assets or otherwise
materially and adversely affect any of the Wilshire Med Assets or the Business.

         4.5   Insurance. Wilshire Tech has provided to either Horizon Med or
Acacia Texas a copy of each insurance policy currently in effect that insures
Wilshire Tech against losses or damages and other risks in respect of the
operations of the Business. Wilshire Tech has not received any notice of
cancellation or material amendment of any such policies; no coverage thereunder
is being disputed; and all material claims thereunder have been filed in a
timely fashion.

         4.6   Intellectual Property Rights. Except with respect to the license
agreements set forth on Exhibit 1.4 hereto, the Intangible Property Rights
constitute the only material intangible property used by Wilshire Tech in the
Business and, after the Closing Date, Acacia Texas shall have the exclusive
right to use all of the Intangible Property Rights in the Business consistent
with Wilshire Tech's use of the Intangible Property Rights in the Business.
Except as set forth on Exhibit 4.6 hereto, to the best of Wilshire Tech's
knowledge, Wilshire Tech owns, or holds adequate licenses, or other rights to
use, all of the Intangible Property Rights, such use does not conflict with,
infringe on, or otherwise violate any rights of any other person and Wilshire
Tech has taken all necessary or appropriate actions to protect the Intangible
Property Rights. Wilshire Tech has not granted, transferred, or assigned any
right, license, or


                                      - 9 -
   10
interest in any of its Intangible Property Rights. To the best of Wilshire
Tech's knowledge after diligent inquiry, Wilshire Tech has not infringed, is not
now infringing, and has not received notice of any infringement, on any patent,
trade name, trademark, service mark, copyright, trade secret, trade dress,
design, invention, technology, know-how, process or other proprietary right
belonging to any other person, firm, or corporation, which infringement would
have an adverse effect on any of the Wilshire Med Assets or the Business. To the
best of Wilshire Tech's knowledge, there is no infringement by any other person
of any Intangible Property Right.

         4.7   FDA Registered Facility; Good Manufacturing Practices. The 
facility from which the Wilshire Med Business is conducted is registered with
the U.S. Food and Drug Administration ("FDA"), which facility manufactures
products relating to the Business in accordance with the FDA's current good
manufacturing practices ("GMP") requirements. Such facility was most recently
audited by the FDA in January of 1996 and did not receive a 483 inspection
report. Without limitation of the foregoing representation and warranty, in
respect of the Business, Wilshire Tech further represents and warrants as
follows that:

               (a)    It has properly filed pre-market notices under Section
         510(k) of the FD&C Act for all products relating to the Business, which
         have been commercially distributed or introduced into interstate
         commerce for commercial distribution by Wilshire Tech and which require
         the filing of such notices.

               (b)    Wilshire Tech has been, from and after January 1, 1994,
         and is in material compliance with all applicable FDA GMP requirements.

               (c)    Wilshire Tech registered with the FDA, to the extent such
         registration is required by FDA regulations, and all of Wilshire Tech's
         medical devices relating to the Business are listed with the FDA, to
         the extent such listing is required by FDA regulations.

               (d)    Wilshire Tech has investigational device exemptions for
         all products relating to the Business requiring such exemptions, and
         such products have not been and are not being sold or distributed
         outside the terms of such investigational device exemptions.

               (e)    To Wilshire Tech's knowledge, Wilshire Tech's marketed
         devices (1) have not caused or contributed to a death or serious injury
         or (2) malfunctioned such that the device would be likely to cause or
         contribute to a death or serious injury.

         4.8   Product Recalls. None of the products manufactured by or on 
behalf of Wilshire Tech in respect of the operations of the Business has been
the subject of any recall. For purposes hereof, "recall" means, with respect to
any such product, that Wilshire Tech has, after reasonable determination, or
after request by the FDA or any other appropriate regulatory authority, ceased
the sale of such product and provided public notice requesting return to
Wilshire Tech of all quantities of such product sold by Wilshire Tech, directly
or indirectly, prior to the date of such public notice.

         4.9   Title to Properties. Except as set forth on Exhibit 1.3, Wilshire
Tech has good and marketable title to all of the Wilshire Med Assets, all of
which are free and clear of liens and encumbrances. All material leases pursuant
to which Wilshire Tech is a lessee of real or personal property in respect of
the operations of Wilshire Med are valid and binding. A copy of the Wilshire Med
Sublease, pursuant to which the Wilshire Med conducts its business is attached
to the Agreement as Exhibit 4.9-a. The form of assignment agreement among
Advanced Materials, Inc., as landlord, Wilshire Tech, as subtenant and assignor,
as Acacia Texas, as assignee, (the "Wilshire Med Sublease Assignment Agreement")
is attached to this Agreement as Exhibit 4.9-b. At the Closing Date, Wilshire
Tech will convey and transfer to Acacia Texas, good, complete, and marketable
title to all of the Wilshire Med Assets, free and clear of all mortgages, liens,
security interests, encumbrances, pledges, leases, equities, claims, charges,
restrictions, conditions, conditional sale contracts, and any other adverse
interests of any kind whatsoever. All of the Wilshire Med Assets are in the
exclusive possession and control of Wilshire Tech and Wilshire Tech has the
unencumbered right to use and sell to Acacia Texas all of the Wilshire Med
Assets without interference from others. The Wilshire Med Assets constitute all
of the assets, properties, rights, privileges, and interests that (i) Wilshire
Tech uses or holds for use exclusively in connection with the Business; and (ii)
are necessary for Acacia Texas to own and operate the Business following the
Closing Date substantially in the same manner as it has been conducted by
Wilshire Tech during the fiscal year ended November 30, 1995.

         4.10  Litigation. In respect of the operations of the Business, there
are neither any actions, suits, proceedings, orders, investigations, or claims
(whether or not purportedly on behalf of Wilshire Tech) pending, or to the best
knowledge of Wilshire Tech, against or affecting Wilshire Tech at law or in
equity or before or by any federal, state, municipal, or other governmental
department, commission, board, agency, or instrumentality, domestic or foreign,
nor are any such actions, suits, proceedings, or investigations pending or, to
the best knowledge of Wilshire Tech, threatened (i) which seek to or could
prohibit, restrict, or delay the consummation of the Wilshire Med Asset purchase
and the Wilshire Med Sublease assumption, or either of them, contemplated
hereby, or (ii) which may in time become a claim against either Horizon Med or
Acacia Texas. In respect of the operations of the Business, Wilshire Tech is not
operating under or subject to, or in default with respect to, any order, writ,
injunction, or decree of any court or federal, state, municipal, or other
governmental department, commission, board, agency, or instrumentality.

         4.11  No Defaults. Wilshire Tech is not in default under or in 
violation of any provision of its Articles of Incorporation or Bylaws. Wilshire
Tech is not in violation of any statute, law, ordinance, order, judgment, rule,
regulation, permit, franchise, or other approval or authorization of any court
or governmental agency or body having jurisdiction over it or any of its
properties which, if enforced, would have a material, adverse effect on the
Business or the Wilshire Med Assets. Neither the execution and delivery of this
Agreement, nor the consummation of the transactions contemplated herein, will
conflict with or result in a breach of or constitute a default under any of the
foregoing or result in the creation of any lien, mortgage, pledge, charge, or
encumbrance upon any of the Wilshire Med Assets, or will cause the cessation or
termination of any other business relationship or arrangement between Wilshire
Tech and any third party that is material to the Business or any of the Wilshire
Med Assets, and, except as set forth in Exhibit 4.11, no consents or waivers
thereunder are required to be

Horizon Med nor Acacia Texas has made any representations or warranties to
Wilshire Tech regarding the collectibility or value of the Accounts Receivable
or the reasonableness of the allowance for doubtful accounts thereof. Subject to
full compliance by each of Horizon Med and Acacia Texas with their post-closing
undertakings set forth in Section 5.2(g), below, Wilshire Tech expressly assumes
the entire risk of collection of the Accounts Receivable.

         4.14   Conduct of Business Pending the Closing Date. Except as 
otherwise consented to by Acacia Texas in writing, for actions to be taken to
the contrary, between the Effective Date and the Closing Date, and until the

   19
The liability of Wilshire Tech for Wilshire Tech's Indemnified Obligations shall
be subject to the following limitations:

                         (i)   Wilshire Tech shall not be liable for Wilshire
                  Tech's Indemnified Obligations unless it has received written
                  notice of a claim asserted under Section 10.1 hereof on or
                  before the expiration of the 12th month following the Closing
                  Date.

                        (ii)   No such claim shall be asserted unless the
                  aggregate of all claims for Wilshire Tech's Indemnified
                  Obligations shall exceed $10,000, whereupon Wilshire Tech
                  shall be liable for all amounts, including the threshold of
                  $10,000.

         10.2     Horizon's Indemnified Obligations. Subject to the limitations 
set forth in this Section 10, each of Horizon Med and Acacia Texas shall
indemnify and hold Wilshire Tech harmless from and against the following (herein

                  (a)  any and all liabilities, losses, damages, claims, costs,
         and expenses of Wilshire Tech and its officers, directors, employees,
         successors, and assigns, of any nature, whether absolute, contingent,
         or otherwise, that arise from or are in connection with: (i) any breach
         of the representations or warranties of either or both of Horizon Med
         or Acacia Texas contained in this Agreement or in any Exhibits or
         Schedules hereto or any certificates or other documents delivered
         hereunder by or on behalf of either or both of Horizon Med or Acacia
         Texas; (ii) any breach or default by either or both of Horizon Med or
         Acacia Texas of any of their respective covenants or agreements
         contained in this Agreement; and

                  (b)  any and all actions, suits, proceedings, demands, 
         assessments, or judgments, costs and expenses incident to any of the
         foregoing.

The liability of each of Horizon Med and Acacia Texas for Horizon's Indemnified
Obligations shall be subject to the following limitations:

                        (i)   Each of Horizon Med and Acacia Texas shall not
                  be liable for Horizon's Indemnified Obligations unless either
                  has received written notice of a claim asserted under Section
                  10.2 hereof on or before the expiration of the 12th month
                  following the Closing Date.

                       (ii)   No such claim shall be asserted unless the
                  aggregate of all claims for Horizon's Indemnified Obligations
                  shall exceed $10,000, whereupon Wilshire Tech shall be liable
                  for all amounts, including the threshold of $10,000.

         10.3     Notification; Assumption of Defense. Any party entitled to
indemnification hereunder (the "Indemnified Party") shall promptly give written
notice to the indemnifying party (the "Indemnifying Party") after the
Indemnified Party has knowledge of any claim against the Indemnifying Party as
to which recovery may be sought against the Indemnified Party because of the
indemnity set forth Sections 10.1 and 10.2 hereunder, or of the commencement of
any


                                     - 19 -
   20
legal proceedings against the Indemnified Party as to such claim after the
Indemnified Party has knowledge of such proceedings, whichever shall first
occur, and shall permit the Indemnifying Party to assume the defense of any such
claim or any litigation resulting from such claim. Failure by the Indemnifying
Party to notify the Indemnified Party of its election to defend any such action
within 30 days after notice thereof shall have been given to the Indemnifying
Party shall be deemed a waiver by the Indemnifying Party of its right to defend
such action. If the Indemnifying Party assumes the defense of any such claim or
litigation resulting therefrom, the obligations of the Indemnifying Party
hereunder as to such claim shall be limited to taking all steps necessary in the
defense or settlement of such claim or litigation resulting therefrom and to
holding the Indemnified Party harmless from and against any and all losses,
damages, and liabilities caused by or arising out of 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 any litigation resulting therefrom, consent to entry of any
judgment except with the written consent of the Indemnified Party, or 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 of a release from all liability in
respect of such claim or litigation.

         10.4   Failure to Assume. If the Indemnifying Party shall not assume 
the defense of any such claim or litigation resulting therefrom, the Indemnified
Party may defend against such claim or litigation in such manner as it may deem
appropriate and unless the Indemnifying Party shall deposit with the Indemnified
Party a sum equivalent to the total amount demanded in such claim or litigation
plus the Indemnified Party's estimate of the cost of defending the same, the
Indemnified Party may settle such claim or litigation on such terms as it may
deem appropriate, in its reasonable judgment, and the Indemnifying Party shall
promptly reimburse the Indemnified Party for the amount of all expenses, legal
or otherwise, incurred by the Indemnified Party in connection with the defense
against or settlement of such claim or litigation. If no settlement of such
claim or litigation is made, the Indemnifying Party shall promptly reimburse the
Indemnified Party for the amount of any judgment rendered with respect to such
claim or in such litigation and of all expenses, legal or otherwise, incurred by
the Indemnified Party in the defense against such claim or litigation.

         11.2   Time of the Essence.  Time shall be of the essence of this 
Agreement.

         11.3   Offers of Employment. For so long as any principal of the
Promissory Note remains outstanding and unpaid, Wilshire Tech covenants not to
offer to employ any individual who, as of the date five business days prior to
the Closing Date, was employed by Wilshire Med, subject to such individual
becoming an employee of Acacia Texas as of the Closing Date; provided, however,
that such covenant shall terminate upon the earlier of (i) an event of default
by Acacia Texas under the Promissory Note or (ii) with respect to any such
individual, the cessation of the employment relationship between such individual
and Acacia Texas, unless such cessation was prompted, directly or indirectly, by
Wilshire Tech. Notwithstanding the above, the parties agree that each may make
an offer of employment or continued employment to Sarah Casey and that her
acceptance of either offer or rejection of both offers is not contemplated by
the parties as a material term or condition of this Agreement and, therefore,
shall not be deemed to affect the transaction contemplated hereby.

         11.4   Entire Agreement and Amendment. This Agreement and the documents
delivered at the Closing Date hereunder contain the entire agreement between the
parties hereto with respect to the transactions contemplated by this Agreement
and supersede all other agreements, written or oral, with respect thereto. This
Agreement may be amended or modified in whole or in part, and any rights
hereunder may be waived, only by an agreement in writing, duly and validly
executed in the same manner as this Agreement or by the party against whom the
waiver would be asserted. The waiver of any right hereunder shall be effective
only with respect to the matter specifically waived and shall not act as a
continuing waiver unless it so states by its terms.

         11.5   Counterparts. This Agreement may be executed in one or more
counterparts each of which shall be deemed to constitute an original and shall
become effective when one or more counterparts have been signed by each party
hereto and delivered to the other party.

         11.6   Governing Law.  This Agreement shall be governed by, and 
construed and interpreted in accordance with, the laws of the State of 
California.

         11.7   Successors and Assigns. This Agreement shall inure to the 
benefit of and be binding upon the parties hereto and their respective heirs,
executors, personal representatives, successors, and assigns as the case may be.

                                 PROMISSORY NOTE

U.S. $540,000.00                                           Carlsbad, California
                                                                   May 31, 1996

         1. Promise to Pay. The undersigned, ACACIA LABORATORIES OF TEXAS, INC.,
a Texas corporation (the "Maker"), promises to pay WILSHIRE TECHNOLOGIES, INC.,
a California corporation (the "Holder"), the sum of Five Hundred Forty Thousand
and No/100 Dollars ($540,000.00) and interest thereon at a rate of five percent
(5%) per annum from the date hereof until this Note is fully paid.

         2. Accrued Interest. Accrued Interest shall be payable monthly in
arrears commencing on July 31, 1996, with respect to interest accruing during
the preceding period, and continuing on the last day of each succeeding month
until all principal is paid in full. Interest hereunder is computed on the basis
of a year of three hundred sixty (360) days for the actual number of days
elapsed. Notwithstanding the above, interest shall commence to accrue hereunder
from and after the Closing Date (as that term is defined in the Purchase of
Assets and Assumption of Sublease Agreement (the "Asset Purchase Agreement").)

         3. Manner of Payment. Principal and interest shall be payable in
thirty-six (36) equal monthly payments of Sixteen Thousand One Hundred
Eighty-four and 28/100 Dollars ($16,184.28) beginning July 31, 1996, and
continuing on the last day of each month thereafter. All remaining principal and
accrued but unpaid interest thereon shall be payable in full on June 30, 1999.
Both principal hereof and interest thereon are payable in lawful money of the
United States of America at the offices of Holder as indicated in the Asset
Purchase Agreement.

         4. Late Charges. If any amount payable hereunder is not paid within
fifteen (15) days of the date it becomes due, Maker shall pay, at Holder's
option, a late or collection charge equal to five percent (5%) of the unpaid
amount. Further, any amount payable hereunder that is not paid when due shall
bear interest at the rate of ten percent (10%) per annum from the date such
amount became due.

         5. Security. This Note is secured by a security agreement and by UCC-1
financing statements (together, the "Security Documents") of even date herewith,
encumbering the assets of Maker set forth in the aforementioned security
agreement. Holder's security interest in and to such assets of Maker acquired
pursuant to the terms and conditions of the Asset Purchase Agreement shall not
be subordinated to any other creditor of, or lender to Maker.

         6. Optional Acceleration. Holder may, at its sole option, declare all
sums owing under this Note immediately due and payable upon the occurrence of a
default or breach under this Note, a breach of Sections 2.3, 3.5, 5.2(j), (k),
or (l), or 10 of the Asset Purchase Agreement, or a material breach under the
terms of the Security Documents, which breach under this Note or the terms of
the Security Documents remains uncured for a period of fifteen (15) days after
notice thereof has been given to Holder.

                                      - 1 -
   26
         7. Mandatory Acceleration.  Upon the closing of a registered public 
offering of any securities of Acacia Laboratories, Inc. a California corporation
that also does business under the name Horizon Medical, Inc., whether or not
such offering is underwritten, all sums owing under this Note shall be
immediately due and payable.

         8. Affirmative Covenants.  As long as any of Maker's obligations 
hereunder remain outstanding or owing, Maker shall, unless Holder otherwise
consents in writing:

                  (a) Duly pay and discharge all other indebtedness and
obligations, except such as Maker may contest in good faith and for which
adequate provision is made for the payment thereof if it is found that the same
is an obligation of Maker.

                  (b) Maintain for itself and each of its subsidiaries (a)

or authority, commission, board, bureau, agency or instrumentality having
jurisdiction over Maker or any of its subsidiaries.

         9. Waiver. No previous waiver and no failure or delay by Holder in
acting with respect to the terms of this Note shall constitute a waiver of any
breach, default, or failure of condition under this Note, the Security Documents
or the obligations secured thereby. A waiver of any term of this Note or the
Security Documents must be made in writing and shall be limited to the express
written terms of such waiver.

         10. Attorney's Fees. If any attorney is engaged by Holder or Maker to

appropriate) shall immediately pay on demand all attorneys' fees and all other
costs incurred by Holder or Maker (as appropriate), together with interest

                                                                         ----- 
                               SECURITY AGREEMENT

         THIS SECURITY AGREEMENT (the "Security Agreement") is made and dated as
of May 31, 1996, between ACACIA LABORATORIES OF TEXAS, INC., a Texas corporation
(the "Debtor"), and WILSHIRE TECHNOLOGIES, INC., a California corporation (the
"Secured Party").

                                    RECITALS

         A. Pursuant to a Purchase of Assets and Assumption of Sublease
Agreement (the "Asset Purchase Agreement") of even date herewith, Secured Party
has sold those certain assets specified in the Asset Purchase Agreement to
Debtor for consideration that includes a promissory note (the "Note") in the
amount of Five Hundred Forty Thousand Dollars ($540,000.00).

         B. Debtor's execution and delivery of this Security Agreement 
constitutes one of the closing activities under the Asset Purchase Agreement.

         1. Security Interest. Debtor hereby grants a security interest pursuant
to the Uniform Commercial Code to Secured Party in the assets of Debtor
described in Section 2, below ("Collateral"), to secure payment and performance

         2. Collateral. The Collateral of Debtor includes the following, and 
shall be limited to such Collateral which has an aggregate value not less than
120% of the amounts owing under the Note at the time Secured Party's rights are
to be enforced hereunder:

                  (a) All inventory of Debtor, now owned or hereafter acquired,
and all raw materials, work in process, materials used or consumed in Debtor's
business and finished goods, together with all additions and accessions thereto
and replacements therefor, and products thereof;

                  (b) All equipment of Debtor, now owned or hereafter acquired,

catalogues, computer hardware and software, furniture, furnishings, and
fixtures;

                  (c) All documents and instruments now owned or hereafter

additional documents and instruments issued with respect thereto, all voting or
other rights now or hereafter exercis- able and all cash and non-cash dividends
and all other property now or hereafter receivable with respect to any of the
foregoing;

                  (d) All now existing and hereafter acquired books and records
relating to the foregoing Collateral and all equipment containing such books and
records;

possession, custody or control of Secured Party and all property of Debtor in
which Secured Party now has or hereafter acquires a security interest; and

                  (f) All proceeds of the foregoing Collateral. For purposes of
this Agreement, the term "proceeds" includes whatever is receivable or received
when Collateral or proceeds is sold, collected, exchanged or otherwise disposed
of, whether such disposition is voluntary or involuntary, and includes, without
limitation, all rights to payment, including return premiums, with respect to
any insurance relating thereto; provided, however, "proceeds" shall not include
any receivables to be paid to Debtor.

         3. Obligations. The obligations ("Obligations") secured by this
Security Agreement shall consist of all obligations of Debtor under the Note and
Section 3.5 of the Asset Purchase Agreement and all reasonable sums and
expenses, including attorneys' fees advanced or incurred by Secured Party in
connection with Secured Party's collection thereof and enforcement hereof.

         4. Collateral Agreements. As to Collateral, (a) Debtor will: (1) except
to the extent expressly permitted under the terms of the Note, keep it free of
all levies, liens, encumbrances and other security interests; (2) comply with
all laws, statutes and regulations pertaining to it, the non-compliance with
which would have an adverse effect on Secured Party's rights hereunder or under
the Note; (3) pay when due all taxes, licenses, charges and other impositions on
or for it, provided that Debtor may contest the same in good faith so long as in
conjunction therewith Debtor posts appropriate bond(s) or otherwise takes all
necessary and appropriate steps to fully protect Secured Party's interest in the
Collateral and to forestall and prevent foreclosure upon or realization of other
remedies against the Collateral in satisfaction of any such tax, license, charge
or other imposition; (4) execute, file and record such statements, notices and
agreements, take such action and obtain such certificates and documents, in
accordance with all applicable laws, statutes, and regulations, as may
reasonably be requested by Secured Party from time to time as may be reasonably
necessary to perfect, evidence and continue Secured Party's security interest in
it; (5) upon demand, give Secured Party such information as reasonably requested
concerning it and Debtor's business, and permit Secured Party to inspect and
copy the records thereof at Secured Party's expense, and subject to Secured
Party entering into a reasonable Confidentiality Agreement in a form provided by
Debtor; (6) keep or require any goods which are security for or represented by
it to be insured in amounts, on terms and with carriers comparable with those as
in existence on the date hereof; and (7) as appropriate, properly care for,
house, store and maintain it and any goods represented by it in good condition,
free of misuse, abuse, waste and deterioration, and prepare it for sale or
market according to approved methods, and promptly and duly observe and perform
any contract or agreement pertaining to or part of it; (b) Debtor will not,
without Secured Party's written consent: (1) exchange, lease, lend, use,
operate, demonstrate, sell or dispose of it or Debtor's rights therein other
than in the ordinary course of business or permit it to be or become so affixed
to realty as to be part of or become a fixture thereof; except that until
otherwise notified by Secured Party, equipment goods may be used in the regular
course of Debtor's business for their intended use only and replaced as
necessitated by reasonable wear and tear, and inventory goods or raw materials
may be used, and inventory goods held for sale may be sold, in the regular
course of Debtor's business; (2) as appropriate, remove it from or outside of
Debtor's chief place of business or other site on which Collateral has been
located only after prior written notice to Secured Party; or (3) permit anything
to be done that may impair, or fail to do anything reasonably necessary or
advisable to preserve, its value and the security and insurance coverage.

                                      - 2 -

         5. Default. Upon the happening of any default in payment or performance
of Debtor's Obligations or the failure of Debtor to cure within fifteen (15)
days following the giving of notice thereof by Secured Party to Debtor, any
material breach of Debtor's covenants and agreements pursuant to this Security
Agreement; then Secured Party, at its election and in addition to all other
rights, powers and privileges, may (1) declare the unpaid balance, in whole or
in part, of Debtor's Obligations immediately due and payable without demand or
notice and proceed to collect same; (2) waive or remedy any default without
waiving it or any prior or subsequent default; (3) terminate any agreement for
financial accommodation, and (4) as appropriate, take possession of Collateral
with or without legal process or require Debtor to assemble it and make it
available to, and at a reasonably convenient place designated by, Secured Party
and, upon giving fifteen (15) days prior written notice to Debtor, sell it at
public sale upon commercially reasonable terms, in the county where located or
where this agreement was made or at private sale upon commercially reasonable
terms and whether or not Collateral is present at the place of sale.

         6. No Subordination.  The security interest granted herein shall not be
subordinated to any other creditor of, or lender to Debtor.

         7. Termination.

                  (a) This Security Agreement and the security interest granted
to Secured Party by Debtor hereunder shall terminate when all of the Debtor's
Obligations are paid to Secured Party in full or otherwise satisfied or
terminated.

                  (b) Promptly upon termination of this Security Agreement,
Secured Party agrees to execute and file with the California Secretary of State
a termination statement on Form UCC-2 terminating Secured Party's security
interest in the Collateral. This subparagraph (b) is subject to specific
performance and injunctive relief for the benefit of Debtor in the event of a
failure by Secured Party to comply duly with a reasonable request for such
compliance.

         8. General.

                  (a) Such care as Secured Party gives to the safekeeping of its
own property of like kinds shall constitute reasonable care of Collateral when
in Secured Party's possession, but Secured Party is not required to make
presentment, demand or protest, or give notice and need not take action to
preserve any rights against prior parties in connection with any obligation or
evidence of indebtedness held as Collateral.

                  (b) After the occurrence of a default under Section 6, Secured
Party, in its own or Debtor's name and at any time upon giving at least five (5)
days prior written notice to Debtor and at Debtor's reasonable expense, may, but
is not obligated to: (1) notify any obligor or account debtor on Collateral to
make payment to Secured Party; (2) collect by legal proceedings or otherwise and
endorse, receive and receipt for all dividends, interest, payments, proceeds and
other sums and property now or hereafter payable on or on account of Collateral;
(3) enter into any extension, reorganization, deposit, merger, consolidation or
other agreement pertaining to, or deposit, surrender, accept, hold or apply
other property in

                                      - 3 -
   31
exchange for, Collateral; (4) insure, process and preserve Collateral; (5)
transfer Collateral to its own or its nominee's name; (6) make any compromise or
settlement, and take any action it deems advisable in its reasonable discretion,
and upon demand Debtor will pay the same to Secured Party together with any
deficiency or balance on Debtor's Obligations remaining after any sale or other
disposition of Collateral by Secured Party, with interest at 10% per annum or as
agreed, which interest shall only accrue ten (10) days after such payment is
due.

                  (c) Debtor will give Secured Party prior written notice of any
change of place of business and address thereof and all policies or certificates
of insurance required for Collateral.

                  (d) This is a continuing agreement and applies to all present
and future obligations of Debtor to Secured Party, and whether or not such
obligations continue, increase, decrease or create new indebtedness and
notwithstanding the bankruptcy of, or other event or proceedings affecting
Debtor.

                  (e) Time is of the essence. Acceptance of partial or
delinquent payments or failure to exercise any right, power or remedy shall not
waive any obligation of Debtor or modify this Agreement. Secured Party, its
successors and assigns, have all rights, powers and remedies herein and as
provided by law, including those of a secured party under the Uniform Commercial
Code, and may exercise the same and effect any set-off and proceed against
Collateral or other security for Debtor's Obligations at any time.

         9. Cumulative Rights. The rights, powers and remedies of Secured Party
under this Security Agreement shall be in addition to all rights, powers and
remedies given to Secured Party by virtue of any statute or rule of law, or any
other agreement between Debtor and Secured Party or otherwise, all of which
rights, powers and remedies shall be cumulative and may be exercised
successively or concurrently without impairing Secured Party's security interest
in the Collateral.

         10. Waiver. Any forbearance or failure or delay by Secured Party in
exercising any right, power or remedy shall not preclude the further exercise
thereof, and every right, power or remedy of Secured Party shall continue in
full force and effect until such right, power or remedy is specifically waived
in a writing executed by Secured Party. Debtor waives any right to require
Secured Party to proceed against any person or to exhaust any Collateral or to
pursue any remedy in Secured Party's power.

         11. Binding Upon Successors.  All rights of Secured Party under this 
Security Agreement shall inure to the benefit of its successors and assigns, and
all obligations of Debtor shall bind its successors and assigns.

         12. Entire Agreement; Severability. This Security Agreement contains
the entire agreement between Secured Party and Debtor with respect to the
subject matter hereof. If any of the provisions of this Security Agreement shall
be held invalid or unenforceable, this Security Agreement shall be construed as
if not containing those provisions and the rights and obligations of the parties
hereto shall be construed and enforced accordingly.

         13. Choice Of Law. This Security Agreement shall be construed in
accordance with and governed by the internal laws of the State of California,

                               CORPORATE GUARANTY

                                                           Carlsbad, California

         For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, and to induce Wilshire Technologies, Inc., a
California corporation (the "Holder") to enter into that certain Purchase of
Assets and Assumption of Sublease Agreement of even date herewith among Holder,
Acacia Laboratories of Texas, Inc., a Texas corporation ("Acacia Texas"), and
Acacia Laboratories, Inc., a California corporation that also does business
under the name Horizon Medical, Inc. ("Horizon Med"), and all other
certificates, documents, agreements, or instruments executed and delivered in
connection therewith (the "Agreement"), and to make a loan to Acacia Texas, of
which Horizon Med is the sole shareholder, which loan is evidenced by that
certain promissory note (the "Note") of Acacia Texas, of even date herewith, in
the initial principal amount of Five Hundred Forty Thousand Dollars
($540,000.00), the undersigned, hereby absolutely and unconditionally,
guaranties to Holder the full and prompt payment when due, whether at maturity
or earlier by reason of acceleration or otherwise, of any and all present and
future debts, liabilities, and obligations owed by Acacia Texas to Holder
pursuant to the terms of the Note and the undersigned hereby acknowledges and   
agrees with Holder that:
        
         1. The debts, liabilities and obligations guarantied hereby
(collectively referred to herein as the "Indebtedness") shall include those
outstanding debts, liabilities, and obligations arising under and pursuant to or
in connection with Sections 2.3, 3.5 and 5.2(j), (k), and (l) of the Agreement
or the Note, including without limitation accrued but unpaid interest thereon
and all legal fees and other costs of collection, whether now existing or
hereafter arising, whether absolute or contingent, direct or indirect, primary
or secondary, sole, joint, several or joint and several, secured or unsecured,
due or not due, contractual, tortious or statutory, liquidated or unliquidated,
arising by agreement or imposed by law or otherwise.

         2. No act or thing need occur to establish the liability of Horizon Med
hereunder, and no act or thing except full payment and discharge of all of the
Indebtedness, shall in any way exonerate Horizon Med hereunder or modify,
reduce, limit or release the liability of Horizon Med hereunder. This is an
absolute, unconditional and continuing guaranty of payment of the Indebtedness
and shall continue to be in force and be binding upon Horizon Med, until paid in
full.

         3. The occurrence of any one of the following events shall constitute
an event of default under this Guaranty, and, upon the occurrence thereof and at
the election of Holder, upon notice or demand, the Indebtedness of Horizon Med
hereunder shall become immediately due, payable and enforceable against Horizon
Med, whether or not the Indebtedness is then due and payable: (1) the occurrence
of any event of default under the Note and the failure to pay upon demand the
obligation of the Guaranty; (2) the commencement of any bankruptcy, insolvency,
receivership, or similar proceeding by Horizon Med (or against Horizon Med if
not cured within 60 days after commencement); (3) the attempt by Horizon Med to
effect an assignment for the benefit of creditors or a composition with
creditors; (4) the insolvency of Horizon Med; or (5) the material breach of any
representation, warranty, cove-

                                      - 1 -
   34
nant, or agreement on the part of Horizon Med under this Guaranty, which breach
remains uncured for a period of fifteen (15) days after notice thereof from
Holder has been given to the undersigned; provided, however, that for a breach
of Sections 2.3, 3.5, and 5.2(j), (k), and (l) of the Agreement, there shall be
no such cure period after notice of such breach has been given to the
undersigned.

         4. Horizon Med hereby waives any right of subrogation Horizon Med may
now or hereafter have against Acacia Texas with respect to the Indebtedness. In
addition, Horizon Med hereby waives any defense based on a right to proceed
against Acacia Texas, now or hereafter, for contribution, indemnity,
reimbursement, and any other suretyship rights and claims, whether direct or
indirect, liquidated or contingent, whether arising under express or implied
contract, or by operation of law, which Horizon Med may now or hereafter have as
against Acacia Texas with respect to the Indebtedness. Horizon Med also hereby
waives any rights to recourse to or with respect to any asset of Acacia Texas.
The waivers set forth in this Section 4 shall continue in effect until the
Indebtedness has been paid in full. To the extent Horizon Med's waiver of these
rights of subrogation, reimbursement or contribution as set forth herein are
found by a court of competent jurisdiction to be void or voidable for any
reason, Horizon Med agrees that Horizon Med's right of subrogation and
reimbursement against Acacia Texas and Horizon Med's right of subrogation
against any collateral or security shall be junior and subordinate to Holder's
rights against Acacia Texas and to Holder's right, title and interest in such
collateral or security, and Horizon Med's right of contribution against any
other guarantor or pledgor shall be junior and subordinate to Holder's rights
against such other guarantor or pledgor.

         5. Horizon Med will pay or reimburse Holder for all costs, expenses and
attorneys' fees reasonably paid or incurred by Holder in endeavoring to collect
and enforce the Indebtedness and in enforcing this Guaranty.

         6. Whether or not any existing relationship between Horizon Med and
Acacia Texas has been changed or ended and whether or not this Guaranty has been
revoked, Holder may enter into transactions resulting in the continuance of the
Indebtedness and may otherwise agree, consent to, or suffer the continuance of
any of the Indebtedness, without any consent or approval by Horizon Med and
without any prior or subsequent notice to Horizon Med. The liability of Horizon
Med shall not be affected or impaired by any of the following acts or things
(which Holder is expressly authorized to do, omit, or suffer from time to time,
both before and after revocation of this Guaranty, without consent or approval
by or notice to Horizon Med): (a) any acceptance of collateral security,
guarantors, accommodation parties or sureties for any or all of the
Indebtedness; (b) one or more extensions or renewals of the Indebtedness
(whether or not for longer than the original period) or any modification of the
interest rate, maturity or other contractual terms applicable to the
Indebtedness or any amendment or modification of any of the terms or provisions
of the Note or Sections 2.3, 3.5, 5.2(j), (k), and (l) of the Agreement under
which the Indebtedness or any part thereof arose; (c) any waiver or indulgence
granted to Acacia Texas, any delay or lack of diligence in the enforcement of
the Indebtedness or any failure to institute proceedings, file a claim, give any
required notices or otherwise protect any of the Indebtedness; (d) any full or
partial release of, compromise or settlement with, or agreement not to sue,
Acacia Texas or any guarantor or other person liable in respect of any of the
Indebtedness; (e) any release, surrender, can-

                                      - 2 -
   35
cellation or other discharge of any evidence of the Indebtedness or the
acceptance of any instrument in renewal or substitution therefor; (f) any
failure to obtain collateral security (including rights of setoff) for the
Indebtedness, or to see to the proper or sufficient creation and perfection
thereof, or to establish the priority thereof, or to preserve, protect, insure,
care for, exercise or enforce any collateral security; or any modification,
alteration, substitution, exchange, surrender, cancellation, termination,
release or other change, impairment, limitation, loss or discharge of any
collateral security; (g) any collection, sale, lease or disposition of, or any
other foreclosure or enforcement of or realization on, any collateral security;
(h) any assignment, pledge or other transfer of any of the Indebtedness or any
evidence thereof; and (i) any manner, order or method of application of any
payments or credits upon the Indebtedness. Horizon Med waives any and all
defenses and discharges available to a surety, guarantor, or accommodation
co-obligor.

         7. Horizon Med expressly agrees that Horizon Med shall be and remain
liable for any deficiency remaining after foreclosure of any security interest
securing the Indebtedness, whether or not the liability of Acacia Texas or any
other obligor for such deficiency is discharged pursuant to statute or judicial
decision. The liability of Horizon Med shall not be affected or impaired by any
voluntary or involuntary liquidation, dissolution, sale or other disposition of
all or substantially all the assets, marshalling of assets and liabilities,
receivership, insolvency, bankruptcy, assignment for the benefit of creditors,
reorganization, arrangement, composition or readjustment of, or other similar
event or proceeding affecting, Acacia Texas or any of its assets. Horizon Med
will not assert, plead or enforce against Holder any claim, defense or setoff
available to Horizon Med against Acacia Texas.

         8. Holder shall not be required first to resort for payment of the
Indebtedness to Acacia Texas or other persons, or their properties, or first to
enforce, realize upon or exhaust any collateral security for the Indebtedness,
before enforcing this Guaranty.

         9. If any payment applied by Holder to the Indebtedness is thereafter
set aside, recovered, rescinded, or required to be returned for any reason
(including, without limitation, the bankruptcy, insolvency or reorganization of
Acacia Texas or any other obligor), the Indebtedness to which such payment was
applied shall for the purpose of this Guaranty be deemed to have continued in
existence, notwithstanding such application, and this Guaranty shall be
enforceable as to such Indebtedness as fully as if such application had never
been made.

         10. Horizon Med acknowledges and agrees that Holder (a) has not made
any representations or warranties with respect to, (b) does not assume any
responsibility to Horizon Med for, and (c) has no duty to provide information
to Horizon Med regarding the enforceability of any of the Indebtedness or the
financial condition of Acacia Texas or any guarantor. Horizon Med has
independently determined the creditworthiness of Acacia Texas and the 
enforceability of the Indebtedness and until the Indebtedness is paid in full
will independently and without reliance on Holder continue to make such
determinations.
        
         11. This Guaranty shall be effective upon delivery to Holder, without
further act, condition or acceptance by Holder, shall be binding upon Horizon
Med and its successors and assigns and shall inure to the benefit of Holder and
its successors and assigns. Any invalidity

                                      - 3 -
   36
or unenforceability of any provision or application of this Guaranty shall not
affect other lawful provisions and applications thereof, and to this end the
provisions of this Guaranty are declared to be severable. This Guaranty may not
be waived, modified, amended, terminated, released, or otherwise changed except
by a writing signed by Horizon Med and Holder. This Guaranty shall be governed
by and interpreted and enforced in accordance with the internal laws of the
State of California, without giving effect to its conflicts-of-law provisions or
interpretations. Horizon Med waives notice of Holder's acceptance hereof.
Horizon Med irrevocably (a) agrees that any suit, action or other legal
proceeding arising out of or relating to this Guaranty may be brought in a court
of record in the State of California or in the Courts of the United States
located in such State, (b) consent to the jurisdiction of each such court in any
suit, action or proceeding, (c) waives any objection which he may have to the
venue of any such suit, action or proceeding in any such courts and any claim
that any such suit, action or proceeding has been brought in an inconvenient
forum, and (d) agrees that a final judgment in any such suit, action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.

         12. Horizon Med has had the opportunity to review the matters discussed
and contemplated by the Note, including the remedies Holder may pursue against
Acacia Texas in the event of a default under the Note, and Acacia Texas'
financial condition and ability to perform under the Note. Horizon Med further
agrees to keep itself fully informed on all aspects of Acacia Texas' financial
condition and the performance of Acacia Texas' obligations to Holder and that
Holder has no duty to disclose to Horizon Med any information pertaining to
Acacia Texas or any security or collateral.

         13. The following provisions shall apply (but shall not be deemed to 
limit in any respect the foregoing provisions of this Guaranty):

                  (a) Changes Do Not Affect Liability. Horizon Med hereby waives
the rights and benefits under California Civil Code ("CC") Section 2819, and
agrees that by doing so Horizon Med's liability shall continue even if Holder
alters any obligations under the Indebtedness in any respect or Holder's
remedies or rights against Acacia Texas are in any way impaired or suspended
without Horizon Med's consent.

                  (b) Guarantee of Payment and Performance. Horizon Med's
liability under this Guaranty is a guarantee of payment and performance of the
Note and not of collectibility, and is not conditioned or contingent upon the
genuineness, validity, regularity or enforceability of any of the Indebtedness,
and Horizon Med hereby waives any and all benefits and defenses under CC Section
2810 and agrees that by doing so Horizon Med is liable even if Acacia Texas had
no liability at the time of execution of the Note or thereafter ceases to be
liable. Horizon Med hereby waives any and all benefits and defenses under CC
Section 2809 and agrees that by doing so Horizon Med's liability may be larger
in amount and more burdensome than that of Acacia Texas. Horizon Med's liability
hereunder shall continue until all sums due under the Indebtedness have been
paid in full and shall not be limited or affected in any way by any impairment
or any diminution or loss of value of any security or collateral for the
Indebtedness, Holder's failure to perfect a security interest in it or any
disability or other defense of Acacia Texas or  any other guarantor or pledgor.
        
                                      - 4 -
   37
                  (c) Waivers of Certain Rights and Defenses. Horizon Med hereby
waives any and all benefits and defenses under CC Sections 2845, 2849, and 2850,
including, without limitation, the right to require Holder to (a) proceed
against Acacia Texas or any other guarantor or pledgor, (b) proceed against or
exhaust any security or collateral Holder may hold, or (c) pursue any other
right or remedy for Horizon Med's benefit, and agrees that Holder may proceed
against Horizon Med for the obligations guaranteed herein without taking any
action against Acacia Texas or any other guarantor or pledgor and without
proceeding against or exhausting any security or collateral Holder holds.
Horizon Med agrees that Holder may unqualifiedly exercise at his sole discretion
any or all rights and remedies available to him against Acacia Texas or any
other guarantor or pledgor without impairing Holder's rights and remedies in
enforcing this Guaranty, under which Horizon Med's liabilities shall remain
independent and unconditional. Horizon Med agrees that Holder's exercise of
certain of such rights or remedies may affect or eliminate Horizon Med's right
of subrogation or recovery against Acacia Texas and that Horizon Med may incur a
partially or totally nonreimbursable liability under this Guaranty.

                  (d) Subrogation, Reimbursement, and Contribution Rights.
Horizon Med hereby waives all benefits and defenses under CC Sections 2847, 2848
and 2849 and agrees that Horizon Med shall have no right of subrogation or
reimbursement against Acacia Texas, right of subrogation against any collateral
or security provided for in the Indebtedness and no right of contribution
against any other guarantor or pledgor unless and until all amounts due under
the Indebtedness have been paid in full and Holder has released, transferred or
disposed of all of his right, title and interest in any collateral or security.
To the extent Horizon Med's waiver of these rights of subrogation, reimbursement
or contribution as set forth herein are found by a court of competent
jurisdiction to be void or voidable for any reason, Horizon Med agrees that
Horizon Med's right of subrogation and reimbursement against Acacia Texas and
Horizon Med's right of subrogation against any collateral or security shall be
junior and subordinate to Holder's rights against Acacia Texas and to Holder's
right, title and interest in such collateral or security, and Horizon Med's
right of contribution against any other guarantor or pledgor shall be junior and
subordinate to Holder's rights against such other guarantor or pledgor.

         14. Any notices or other communications required or permitted hereunder
shall be sufficiently given if written and delivered in person or sent by
certified mail, postage prepaid, addressed as follows:

                               SECURITY AGREEMENT

         THIS SECURITY AGREEMENT (the "Security Agreement") is made and dated as
of May 31, 1996, between ACACIA LABORATORIES, INC., a California corporation
that also does business under the name HORIZON MEDICAL, INC. (the "Guarantor"),
and WILSHIRE TECHNOLOGIES, INC., a California corporation (the "Secured Party").

                                    RECITALS

         A.    Pursuant to a Purchase of Assets and Assumption of Sublease
Agreement (the "Asset Purchase Agreement") of even date herewith, Secured Party
has sold those certain assets specified in the Asset Purchase Agreement to
Guarantor's wholly-owned subsidiary, Acacia Laboratories of Texas, Inc. ("Acacia
Texas"), for consideration that includes a promissory note (the "Note") in the
amount of Five Hundred Forty Thousand Dollars ($540,000.00).

         B.    Guarantor's execution and delivery of the Corporate Guaranty and 
of this Security Agreement constitutes certain of the closing activities under
the Asset Purchase Agreement.

         1.    Security Interest.  Guarantor hereby grants a security interest 
pursuant to the Uniform Commercial Code to Secured Party in the assets of
Guarantor described in Section 2, below ("Collateral"), to secure payment and
performance of Guarantor's Obligations described at Paragraph 3 below.

         2.    Collateral. The Collateral of Guarantor includes the following, 
and shall be limited to such Collateral which has an aggregate value not less
than 120% of the difference between the amounts owing under the Note at the time
Secured Party's rights are to be enforced hereunder and the value of the
"Collateral" as defined in the Security Agreement of even date herewith between
Secured Party and Acacia Texas at the time Secured Party's rights are to be
enforced hereunder:

               (a)   All present and future accounts, general intangibles and
other rights of Guarantor to the payment of money no matter how evidenced, all
chattel paper, instruments and other writings evidencing any such right, and all
goods repossessed or returned in connection therewith;

               (b)   All inventory of Guarantor, now owned or hereafter 
acquired, and all raw materials, work in process, materials used or consumed in
Guarantor's business and finished goods, together with all additions and
accessions thereto and replacements therefor, and products thereof;

               (c)   All equipment of Guarantor, now owned or hereafter
acquired, including, without limitation, all machinery, tools, dies, blueprints,
catalogues, computer hardware and software, furniture, furnishings and fixtures;

               (d)   All documents and instruments now owned or hereafter 
acquired, including, without limitation, securities and all new substituted and
additional documents and



                                      - 1 -
   40
instruments issued with respect thereto, all voting or other rights now or
hereafter exercisable and all cash and non-cash dividends and all other
property now or hereafter receivable with respect to any of the foregoing;

               (e)   All now existing and hereafter acquired books and records 
relating to the foregoing Collateral and all equipment containing such books and
records;

               (f)   All other property of Guarantor now or hereafter in the
possession, custody or control of Secured Party and all property of Guarantor in
which Secured Party now has or hereafter acquires a security interest; and

               (g)   All proceeds of the foregoing Collateral. For purposes of
this Agreement, the term "proceeds" includes whatever is receivable or received
when Collateral or proceeds is sold, collected, exchanged or otherwise disposed
of, whether such disposition is voluntary or involuntary, and includes, without
limitation, all rights to payment, including return premiums, with respect to
any insurance relating thereto.

         3.    Obligations. The obligations ("Obligations") secured by this
Security Agreement shall consist of all obligations of Guarantor under the Note
and Sections 2.3, 3.5, and 5.2(j), (k), and (l) of the Asset Purchase Agreement
and all reasonable sums and expenses, including attorneys' fees advanced or
incurred by Secured Party in connection with Secured Party's collection thereof
and enforcement hereof.

         4.    Collateral Agreements. As to Collateral, (a) Guarantor will: (1)
except to the extent expressly permitted under the terms of its financing
arrangements with Union Bank of California N.A. ("Union Bank"), keep it free of
all levies, liens, encumbrances and other security interests; (2) comply with
all laws, statutes and regulations pertaining to it, the non-compliance with
which would have an adverse effect on Secured Party's rights hereunder or under
its financing arrangements with Union Bank; (3) pay when due all taxes,
licenses, charges and other impositions on or for it, provided that Guarantor
may contest the same in good faith so long as in conjunction therewith Guarantor
posts appropriate bond(s) or otherwise takes all necessary and appropriate steps
to fully protect Secured Party's interest in the Collateral and to forestall and
prevent foreclosure upon or realization of other remedies against the Collateral
in satisfaction of any such tax, license, charge or other imposition; (4)
execute, file and record such statements, notices and agreements, take such
action and obtain such certificates and documents, in accordance with all
applicable laws, statutes, and regulations, as may reasonably be requested by
Secured Party from time to time as may be reasonably necessary to perfect,
evidence and continue Secured Party's security interest in it; (5) upon demand,
give Secured Party such information as reasonably requested concerning it and
Guarantor's business, and permit Secured Party to inspect and copy the records
thereof at Secured Party's expense, and subject to Secured Party entering into a
reasonable Confidentiality Agreement in a form provided by Guarantor; (6) keep
or require any goods which are security for or represented by it to be insured
in amounts, on terms and with carriers comparable with those as in existence on
the date hereof; and (7) as appropriate, properly care for, house, store and
maintain it and any goods represented by it in good condition, free of misuse,
abuse, waste and deterioration, and prepare it for sale or market according to
approved methods, and promptly and duly observe and perform any contract or
agreement pertaining to or part of it;


                                      - 2 -
   41
(b) Guarantor will not, without Secured Party's written consent: (1) exchange,
lease, lend, use, operate, demonstrate, sell or dispose of it or Guarantor's
rights therein other than in the ordinary course of business or permit it to be
or become so affixed to realty as to be part of or become a fixture thereof;
except that until otherwise notified by Secured Party, equipment goods may be
used in the regular course of Guarantor's business for their intended use only
and replaced as necessitated by reasonable wear and tear, and inventory goods or
raw materials may be used, and inventory goods held for sale may be sold, in the
regular course of Guarantor's business; (2) as appropriate, remove it from or
outside of Guarantor's chief place of business or other site on which Collateral
has been located only after prior written notice to Secured Party; or (3) permit
anything to be done that may impair, or fail to do anything reasonably necessary
or advisable to preserve, its value and the security and insurance coverage.

         5.    Default. Upon the happening of (i) any default in payment or
performance of Guarantor's Obligations, (ii) or the failure of Guarantor to cure
within fifteen (15) days following the giving of notice thereof by Secured Party
to Guarantor, any material breach of Guarantor's covenants and agreements
pursuant to this Security Agreement or (iii) a "Change-in-Control" (as defined
below), then Secured Party, at its election and in addition to all other rights,
powers and privileges, may (1) declare the unpaid balance, in whole or in part,
of Guarantor's Obligations immediately due and payable without demand or notice
and proceed to collect same; (2) waive or remedy any default without waiving it
or any prior or subsequent default; (3) terminate any agreement for financial
accommodation, and (4) as appropriate, take possession of Collateral with or
without legal process or require Guarantor to assemble it and make it available
to, and at a reasonably convenient place designated by, Secured Party and, upon
giving fifteen (15) days prior written notice to Guarantor, sell it at public
sale upon commercially reasonable terms, in the county where located or where
this agreement was made or at private sale upon commercially reasonable terms
and whether or not Collateral is present at the place of sale. For purposes of
this Section 5, a "Change-in-Control" shall occur when the Guarantor shall merge
or consolidate with, or sell, assign, lease, or otherwise dispose of or
voluntarily part with capital stock or substantially all of its assets (whether
now owned or hereinafter acquired) to any person or entity, except for sales or
other dispositions of assets in the ordinary course of the Guarantor's business
and except that the Guarantor may merge any person or entity into it or
otherwise acquire such person or entity so long as the Guarantor is the
surviving entity or the holders of voting stock of the Guarantor immediately
prior to such merger (or a series of such mergers) are the holders of more than
50% of the Guarantor immediately following such merger(s), without constituting
a "Change-in-Control."

         6.    No Subordination.  The security interest granted herein shall not
be subordinated to any other creditor of, or lender to, Guarantor other than
Union Bank, or a successor bank.

   42
         7.    Termination.

               (a)   This Security Agreement and the security interest granted
to Secured Party by Guarantor hereunder shall terminate when all of the
Guarantor's Obligations are paid to Secured Party in full or otherwise satisfied
or terminated.

               (b)   Promptly upon termination of this Security Agreement,
Secured Party agrees to execute and file with the California Secretary of State
a termination statement on Form UCC-2 terminating Secured Party's security
interest in the Collateral. This subparagraph (b) is subject to specific
performance and injunctive relief for the benefit of Guarantor in the event of a
failure by Secured Party to comply duly with a reasonable request for such
compliance.

         8.    General.

               (a)   Such care as Secured Party gives to the safekeeping of its
own property of like kinds shall constitute reasonable care of Collateral when
in Secured Party's possession, but Secured Party is not required to make
presentment, demand or protest, or give notice and need not take action to
preserve any rights against prior parties in connection with any obligation or
evidence of indebtedness held as Collateral.

               (b)   After the occurrence of a default under Section 6, Secured
Party, in its own or Guarantor's name and at any time upon giving at least five
(5) days prior written notice to Guarantor and at Guarantor's reasonable
expense, may, but is not obligated to: (1) notify any obligor or account debtor
on Collateral to make payment to Secured Party; (2) collect by legal proceedings
or otherwise and endorse, receive and receipt for all dividends, interest,
payments, proceeds and other sums and property now or hereafter payable on or on
account of Collateral; (3) enter into any extension, reorganization, deposit,
merger, consolidation or other agreement pertaining to, or deposit, surrender,
accept, hold or apply other property in exchange for, Collateral; (4) insure,
process and preserve Collateral; (5) transfer Collateral to its own or its
nominee's name; (6) make any compromise or settlement, and take any action it
deems advisable in its reasonable discretion, and upon demand Guarantor will pay
the same to Secured Party together with any deficiency or balance on Guarantor's
Obligations remaining after any sale or other disposition of Collateral by
Secured Party, with interest at 10% per annum or as agreed, which interest shall
only accrue ten (10) days after such payment is due.
 
               (c)   Guarantor will give Secured Party prior written notice of
any change of place of business and address thereof and all policies or
certificates of insurance required for Collateral.

               (d)   This is a continuing agreement and applies to all present
and future obligations of Guarantor to Secured Party, and whether or not such
obligations continue, increase, decrease or create new indebtedness and
notwithstanding the bankruptcy of, or other event or proceedings affecting
Guarantor.


                                      - 4 -
   43
               (e)   Time is of the essence. Acceptance of partial or delinquent
payments or failure to exercise any right, power or remedy shall not waive any
obligation of Guarantor or modify this Agreement. Secured Party, its successors
and assigns, have all rights, powers and remedies herein and as provided by law,
including those of a secured party under the Uniform Commercial Code, and may
exercise the same and effect any set-off and proceed against Collateral or other
security for Guarantor's Obligations at any time.

the occurrence of such damage.

                  B. If the Building of which the Premises are a part, should be
damaged by any peril covered by the insurance to be provided by the landlord
under the Underlying Lease, or effective upon the date of the occurrence of such
damage and ending upon substantial completion, if the Premises are untenantable
in whole or part during such period, the rent shall be reduced to such extent as
may be fair and reasonable under all of the circumstances.

                  C. Notwithstanding anything herein to the contrary, in the
event the holder of any indebtedness secured by a mortgage or deed of trust
covering the Premises requires that the insurance proceeds be applied to such
indebtedness, then Landlord shall have the right to terminate this Lease by
delivering written notice of termination to Tenant within fifteen (15) days
after such requirement is made known to Landlord, whereupon all rights and
obligations hereunder shall cease and terminate (except as expressly provided to
the contrary herein).

         16.      LIABILITY AND INDEMNIFICATION. Except for any claims, rights 
of recovery and causes of action that Tenant has released, Landlord shall hold
Tenant harmless and defend Tenant against any and all claims or liability for
any injury or damage to any person in, on or about the Premises, when such
injury or damage shall be caused by an affirmative act of negligence by such
landlord, its agents, servants and employees (unless the indemnified loss is
caused wholly or in part by Tenant's or any other party's negligence, in which
event this indemnity shall not apply to the allocable share of such loss
resulting from Tenant's or such other party's negligence). Except for any
claims, rights of recovery and causes of action that Landlord has released,
Tenant shall indemnify, protect, hold harmless and defend Landlord, its agents,
employees, contractors, partners, directors, officers and any affiliates of the
above-mentioned parties (collectively the "Landlord Affiliates") from and
against any and all obligations, suits, losses, judgments, actions, damages,
claims or liability (including, without limitation, all costs, attorneys' fees,
and expenses incurred in connection therewith) in connection with any loss,
injury or damage (i) to any person or property whatsoever occurring in, on or
about the Project, when such injury or damage shall be caused by the act,
neglect, fault of, or omission of any duty with respect to the same by Tenant,
its agents, servants, employees, or invitees (ii) arising from the conduct of
management of any work done by or for Tenant in or about the Project, (iii)
arising from transactions of the Tenant, or (iv) arising from a breach,
violation or non-performance of any term, provision, covenant or agreement of
Tenant hereunder, or a breach or violation by Tenant of any court order or any
law, regulation, or ordinance

                                      - 4 -
   50
of any federal, state or local authority (collectively, the "Losses"). If any
claim is made against Landlord or Landlord Affiliates, Tenant, at its sole cost
and expense, shall defend any such claim, suit or proceeding by or through
attorneys satisfactory to Landlord. The provisions of this Paragraph 16 shall
survive the expiration or termination of this Lease with respect to any claims
or liability occurring prior to such expiration or termination.

         18.      INSPECTION. Landlord and Landlord's agents and representatives
(including Landlord and its agents and affiliates under the Underlying Lease)
shall have the right to enter the Premises during business hours, upon prior
reasonable notice except in the event of an emergency, to (i) inspect the
Premises, (ii) make such repairs as may be required or permitted pursuant to
this Lease, and (iii) show the Premises to prospective purchasers of, or parties
who are anticipated to provide financing with respect to, the Building.
Notwithstanding the foregoing, Landlord and landlord under the Underlying Lease
shall have the right to enter the Premises at any time, without notice to
Tenant, in case of an emergency posing a threat to persons or property. Upon
telephonic notice to Tenant, Landlord and Landlord's representatives may enter
the Premises stating the Premises are available. Tenant shall notify Landlord in
writing at least fifteen (15) days prior to vacating the Premises and shall
arrange to meet with Landlord for a joint inspection of the Premises prior to
vacating. If Tenant fails to give such notice or to arrange for such inspection,
then Landlord's inspection of the Premises shall be deemed correct for the
purpose of determining Tenant's responsibility for repairs and restoration of
the Premises.

         22.      QUIET ENJOYMENT. This Lease is a sublease, and Tenant agrees 
to take the Premises subject to the provisions of the prior leases. Landlord
represents that it has the authority to enter into this Lease and that so long
as Tenant pays all amounts due hereunder and performs all other covenants and
agreements herein set forth, Tenant shall peaceably and quietly have, hold and
enjoy the Premises for the Term hereof without hindrance or molestation from
Landlord subject to the terms and provisions of this Lease.

         35.      MISCELLANEOUS.

                  H. During the term of this Sublease, Tenant will provide
Landlord, without charge, the following services currently performed by Sarah
Casey: purchasing, materials management, cost accounting, and inventory control.
In return, Landlord will provide Tenant, without charge, the following
warehouse-related services: shipping, receiving, quality inspection based on
past practices, and inventory storage. Such services will be provided in a
commercially reasonable manner and the provision thereof, where relevant, shall
be consistent with past practice.

                           (a)      Advanced's consent to this Assignment and 
the terms contained in the Estoppel Certificate by its execution of the Estoppel

                           (e)      receipt by Advanced of a payment from 
Assignee in the aggregate sum of $18,151.10, representing payment of the first

Advanced, without obligation for interest, as security for the performance of

                  5.       Assignee's Representations.  Assignee represents and
warrants:

                           (a)      it understands that neither Advanced nor New
York Life has made any express or implied warranties with respect to the
Sublease;

                           (b)      it has had the opportunity to inspect the
Property;

                           (c)      it has been provided with a copy of the 
Lease and Sublease, has read the Lease and Sublease and fully understands its
obligations under the Lease and Sublease;


                                        2
   54
                           (d)      it understands that it is taking the 
property AS IS without any representation or warranty from the Assignor
other than what is contained in this Assignment;

                           (e)      it understands and agrees that (x) Advanced,
notwithstanding the terms of the Sublease, may charge it a late payment penalty
of five percent (5%) of the amount owed, should it fail to make payments when
due under the Sublease and the failure to pay such amount within five (5) days
after demand therefor shall be an additional event of default under the
Sublease; (y) such provision for such late charges shall be in addition to all
of Advanced's other rights and remedies; and (z) in addition, to the extent
allowed by law, rent that is more than 30 days past due shall bear interest at
the highest applicable rate of interest that may then be lawfully charged on
such past due amounts (after taking into account any late charges or other
amounts paid or payable hereunder if and to the extent they are held to
constitute interest) or, if there is no such higher rate, then at a rate equal
to eighteen percent (18%) per annum; and

                           (f)      it understands and agrees that (x) it shall
deposit with Advanced on the date hereof the security deposit referenced in
Section 5(e), above, which shall be held by Advanced, without obligation for
interest, as security for the performance of Assignee's obligations under the
Sublease, it being expressly understood and agreed that such security deposit is
not an advance rental deposit or a measure of Advanced's damages in case of
Assignee's default; (y) upon each occurrence of an event of default under the
Sublease, Advanced may use all or part of such security deposit to pay past due
rent or other payments due Advanced under the Sublease, and the cost of any
other damage, injury, expense or liability caused by such event of default
without prejudice to any other remedy provided therein or provided by law; and
(z) that, on demand, it shall pay Advanced the amount that will restore such
security deposit to its original amount and that such security deposit shall be
deemed the property of Advanced, but any remaining balance of such security
deposit after payment and performance of all of Assignee's obligations under the
Sublease shall be returned to Assignee within 30 days of the end of the
Sublease.

                  6.       Amendment.  That Section of the Sublease entitled
"Renewal Option" shall be replaced by the following:

         "Landlord hereby grants to Tenant the right and option to renew the
         lease on the same terms and conditions as at each of the first three
         (3) anniversaries of the Commencement Date (the "Renewal Option"),
         provided Tenant is not then and has not at any time been in material
         breach of any term of this Lease or an Event of Default has not
         occurred or is continuing. If exercised, the Lease will be renewed for
         an additional twelve (12) month term as a result of each of the first
         two such exercises, and shall be renewed for an additional twenty-four
         (24) month term as a result of the third such exercise with no further
         renewal options unless expressly granted by Land-

   55
         lord in writing. To exercise the Renewal Option, Tenant must give
         Landlord written notice of its exercise at least ninety (90) days prior
         to the respective anniversary date."

Assignee, upon demand, any and all other instruments that Assignee may require
to carry out the intent of this Assignment.

                  8.  No Waiver.  Failure of Assignee to avail itself of any
provisions hereof shall not be a waiver of any of its rights.

to be given to any party hereunder shall be in writing and sent by regular or
certified mail as follows:
