                             DISTRIBUTION AGREEMENT

       This Distribution Agreement ("Agreement"), effective May 1, 1997, is
entered into by and between ORIGIN MEDSYSTEMS, INC., 135 Constitution Drive,
Menlo Park, California, 94025, USA, hereinafter called "ORIGIN", and LIFEQUEST
MEDICAL, INC., whose principal place of business is 9601 McAllister Freeway,
San Antonio, Texas, 98216, USA, hereinafter called "DISTRIBUTOR."

                                    RECITALS

       A.     ORIGIN has established an excellent worldwide reputation as a
manufacturer and seller of high quality lines of medical products which have
been sold and used successfully throughout the world.

       B.      DISTRIBUTOR has acquired two of Origin's existing distributors,
Klein Medical, Inc. ("Klein") and Val-U-Med, and desires to sell ORIGIN
products to the accounts and in the territories that those distributors sold
ORIGIN products, and to certain other accounts and in certain other
territories.

       C.     DISTRIBUTOR represents that it and each of Distributor's
representatives identified on Exhibit A (the "Representatives') have the
capability and resources to promote and sell ORIGIN products in those accounts
and territories listed on Exhibit A hereto, hereinafter referred to as the
"Primary Area of Responsibility," and to fulfill the needs and requirements of
customers for ORIGIN products there.

       D.     ORIGIN desires to appoint DISTRIBUTOR to promote, sell and
distribute ORIGIN products in the Primary Area of Responsibility in accordance
with the terms and conditions stated herein.
                                   AGREEMENT

       IN CONSIDERATION OF THE FOREGOING, it is mutually agreed by and between
the parties as follows:

       1.     Termination of Existing Agreements; Grant.

              (a)    ORIGIN and DISTRIBUTOR hereby agree that the distribution
agreements between ORIGIN and Klein dated November 25, 1996, and between ORIGIN
and Val-U-Med dated August 8, 1996, are hereby terminated and are of no further
force and effect.

              (b)    ORIGIN hereby grants to DISTRIBUTOR THE right to purchase
from ORIGIN those products identified pursuant to Paragraph 2 of this
Agreement, for sale in the Primary Area of Responsibility. DISTRIBUTOR, through
the Representatives, shall have the exclusive rights to sell the products to
the accounts and areas identified in the Distributor Territory Addendum(a)
<PAGE>   2
attached as Exhibit A hereto. ORIGIN appoints DISTRIBUTOR, through the
Representatives, as its representative in the Primary Area of Responsibility to
promote, sell, market, and distribute ORIGIN products there. DISTRIBUTOR hereby
accepts the appointment and agrees to represent ORIGIN on the terms and
conditions set forth herein. ORIGIN shall make available for purchase by
DISTRIBUTOR sufficient quantities of products from those available for sales to
meet DISTRIBUTOR's reasonable needs and requirements in order to fulfill the
terms and conditions of this Agreement. ORIGIN and DISTRIBUTOR may add
additional accounts and/or territories to the Primary Area of Responsibility by
both parties executing a revised or new Distributor Territory Addendum.

              (c)    ORIGIN shall have the right to make sales directly to
customers other than those listed in attached Exhibit A, which is incorporated
herein by reference and made apart hereof. In addition, ORIGIN may sell
private-labeled ORIGIN products directly or through others in the Primary Area
of Responsibility.

              (d)    DISTRIBUTOR and ORIGIN agree that the forecast attached
with the Distributor Territory Addendum as Exhibit A hereto represents the
forecast for each Representative in his area of responsibility identified on
Exhibit A for calendar year 1997 for the total amount (in U.S. Dollars) of
products to be purchased by DISTRIBUTOR from ORIGIN during each month of the
1997 calendar year of this Agreement ("Annual Purchase Commitment"). For each
calendar year after 1997 that this Agreement is in effect, DISTRIBUTOR and
ORIGIN shall mutually agree in writing on a reasonable Annual Purchase
Commitment for the following year. Failure to do so will result in a
probationary three (3) month period. After the probationary period, ORIGIN
shall have the right, at anytime, to terminate DISTRIBUTOR's exclusive right to
sell ORIGIN products in all or any portion of the Primary Area of
Responsibility by notifying DISTRIBUTOR OF such termination.

       If a Representative fails to purchase enough Products to satisfy the
sales forecast for his accounts and/or area in any calendar quarter, ORIGIN
shall have the right, at anytime by providing written notice to DISTRIBUTOR, to
terminate this Agreement as to the accounts and/or area covered by that
Representative as set forth on Exhibit A.

              (e)    DISTRIBUTOR agrees to use its best efforts to develop a
market for ORIGIN products and to enhance  ORIGIN's image in the marketplace as
a provider of quality products. At  the beginning of each calendar year,
DISTRIBUTOR and ORIGIN shall mutually agree in writing on the sales promotion
activities and performance criteria to be met by DISTRIBUTOR for that calendar
year. DISTRIBUTOR shall provide ORIGIN with information concerning products,
competitors, competitor prices, marketing programs and strategies, and with
unit sales reports by customer, ORIGIN product inventory, key accounts and
DISTRIBUTOR business plans. DISTRIBUTOR shall provide ORIGIN with an annual
analysis of the market, including total market size, market share data and
competitive activities. Such information shall, be provided to enable ORIGIN to
assist DISTRIBUTOR in fully developing the market demand for ORIGIN products
and





                                      -2-

in developing appropriate marketing and business plans for the mutual advantage
of DISTRIBUTOR AND ORIGIN.

       2.     Products.

              The products covered by this Agreement are ORIGIN products, as
identified on attached Exhibit D, which is incorporated herein by reference and
made a part hereof, to be sold in the Primary Area of Responsibility as of the
date of this Agreement. If ORIGIN, in its sole discretion, decides to make a
new product available for sales in the Primary Area of Responsibility, ORIGIN
will discuss with DISTRIBUTOR the addition of such product to this Agreement.
In the event ORIGIN decides not to add the product to this Agreement, or if
DISTRIBUTOR decides that it does not want to add the product to this Agreement,
ORIGIN shall have the right to have the product distributed by another
representative. ORIGIN has the right, at its sole discretion, to add to, delete
from or otherwise modify Exhibit D, except those products listed on Exhibit E,
upon thirty (30) days prior written notice to DISTRIBUTOR. ORIGIN may also
discontinue one or more of the products listed oil Exhibit E, but only if
ORIGIN discontinues manufacture of such product.

       3.     Prices.

              (a)    Prices to DISTRIBUTOR shall be in United States dollars
and, initially, according to Exhibit C. ORIGIN shall I not increase the prices
during calendar year 1997 without DISTRIBUTOR's written permission. After
calendar year 1997, changes in price may be made by ORIGIN, subject to thirty
(30) days' notice in advance to DISTRIBUTOR; provided, however, that any
increase in 1998 shall not be greater than two and one-half percent (2.5%) of
the calendar year 1997 prices.. All prices are calculated for delivery F.O.B.
destination. Prices to DISTRIBUTOR do not include any federal, state or local
taxes that may be applicable to products. When ORIGIN has the legal obligation
to collect such taxes, the appropriate amount shall be added to DISTRIBUTOR's
invoice and paid by DISTRIBUTOR unless DISTRIBUTOR provides ORIGIN with a valid
tax exemption certificate authorized by the appropriate taxing authority.

              (b)    The difference in the cost to DISTRIBUTOR of ORIGIN
products and the selling priced charge by DISTRIBUTOR to its customers
represents a payment to DISTRIBUTOR for the following: sales commission,
promotional allowance, compensation for development of goodwill, for
development and maintenance of a sales organization, and/or allowance for
in-service training and other user education.

              (c)    Pursuant to this Agreement the DISTRIBUTOR will submit
purchase orders for the products ("Purchase Orders").  Such Purchase Orders
shall be subject to the terms and conditions contained  herein.

       4.     Payment

              Full payment to ORIGIN of DISTRIBUTOR's purchase price (including
any freight, taxes or other applicable costs) shall be made in the United
States in United States dollars within thirty (30) days of the date of ORIGIN's
invoice to DISTRIBUTOR. Payments not made when due will bear interest at the
rate of 12% per year or the maximum amount permitted by law, whichever is less.

       5.     Diligence and Conflict of Interest

              (a)    DISTRIBUTOR shall exercise due diligence and its best
efforts in promoting and selling ORIGIN products within the Primary Area of
Responsibility, and to enhance, develop, and expand the popularity of, and
demand for, ORIGIN products. DISTRIBUTOR shall promote the products of other
companies only if such promotion will not, in ORIGIN's sole judgment, prejudice
ORIGIN's business interests or create a conflict of interest in handling
ORIGIN's confidential or proprietary information. Immediately prior to the
execution of this Agreement, DISTRIBUTOR shall provide ORIGIN with a list of
the companies and products that it currently represents and shall notify ORIGIN
in writing of any new companies or products at such time as its promotion of
those new companies or products commences.

              (b)    DISTRIBUTOR shall maintain the financial capability to
perform the Distribution Agreement and shall, at its own expense, establish and
maintain sales, marketing and distribution, organization and personnel of
sufficient size to adequately and effectively sell ORIGIN products in the
Primary Area of Responsibility.

              (c)    DISTRIBUTOR shall maintain adequate and accurate books and
records with respect to he sale or distribution of ORIGIN products. DISTRIBUTOR
is responsible for maintaining lot number traceability, so as to know which
customers received which lot numbers of product. ORIGIN shall have the right
during reasonable business hours, to inspect the facilities of DISTRIBUTOR
which are used or provided in connection with the sale, administration and
stocking of ORIGIN products, and to inspect such books and records. Upon
termination of this Agreement, DISTRIBUTOR shall, within thirty (30) days of
written request from ORIGIN, furnish a list, by name and address, of all
customers and users of ORIGIN products made or supplied by DISTRIBUTOR during
the term of this Agreement.

              (d)    DISTRIBUTOR shall provide in-service training for
personnel of customers acquiring ORIGIN products and shall provide necessary
user education for such personnel. ORIGIN shall provide DISTRIBUTOR with
marketing and technical information concerning the products as well as
reasonable quantities of brochures, instructional material, advertising
literature and other product data, provided that all such material will be
printed in the English language. In addition, ORIGIN will supply each
Representative with up to one thousand dollars ($ 1,000) per month in sample
products. The price for such sample products shall be one-half (50%) of the
regular price of such products. The Representative must indicate that the
products being purchased are sample products at the time he or she makes the
purchase, and no part of the one thousand dollars ($ 1,000) per month limit
will carry over from month-to-month.

<PAGE>   5
              (e)    Within 10 days of the end of each calendar month,
DISTRIBUTOR agrees to provide ORIGIN customer service representatives with a
detailed transactional analysis of all product transactions by the
Representatives or DISTRIBUTOR during the preceding calendar month. The
transactional analysis shall include, at a minimum, each customer name, and the
quantity and ORIGIN product numbers of any products sold or transferred to such
customer.

              (f)    Both ORIGIN and DISTRIBUTOR understand, acknowledge and
agree that the continued maintenance of an image of excellence and high level
ethical marketing of ORIGIN products, as outlined in the Guidant Corporation
Code of Business Conduct, is essential to the continued success of both
parties. DISTRIBUTOR agrees that its sales, marketing, distribution, or
advertising will not reflect unfavorably on, or dilute in anyway, ORIGIN's
image of excellence and high level ethical marketing. DISTRIBUTOR agrees that
it shall not do anything, directly or indirectly, to impair the current image
or to lower the prestige or quality of ORIGIN products.

       6.     Delivery, Title, Risk of Loss, and Returns.

              (a)    Firm Purchase Orders are to be placed by DISTRIBUTOR at
least thirty (30) days prior to the required delivery date, and ORIGIN shall
use reasonable commercial efforts to accommodate firm Purchase Orders placed
with a shorter lead time. Products shall be shipped at DISTRIBUTOR's expense in
such manner as ORIGIN shall deem appropriate, or as otherwise directed. Title
and risk of loss for ORIGIN products shall remain with ORIGIN while in transit
until delivery to Distributor, at which time title and risk of loss will shift
to DISTRIBUTOR. DISTRIBUTOR will obtain insurance sufficient to cover the value
of each shipment or shall instruct ORIGIN to obtain such insurance and to bill
DISTRIBUTOR therefor.

              (b)    DISTRIBUTOR shall inspect all products promptly upon
receipt thereof and may reject any product that fails in any material way to
meet the specifications set forth in ORIGIN's current brochure for that
product. Any product not properly rejected within thirty (30) days of receipt
of that product by DISTRIBUTOR (the "Rejection Period") shall be deemed
accepted. To reject a product, DISTRIBUTOR shall, within the Rejection Period,
notify ORIGIN of its rejection and request a Material Return Authorization
("MRA") number. ORIGIN shall provide the MRA number to DISTRIBUTOR within seven
(7) days of receipt of the request. Within seven (7) days of receipt of the MRA
number, DISTRIBUTOR shall return to ORIGIN the rejected product, freight
prepaid, in its original shipping carton with the MRA number displayed on the
outside of the carton. ORIGIN reserves the right to refuse to accept any
rejected products that do not bear all MRA number on the outside of the carton.
As promptly as possible but no later than thirty (30) working days after
receipt of properly rejected products, ORIGIN shall, at its option and expense,
replace the products. ORIGIN shall pay the shipping charges back to DISTRIBUTOR
for properly rejected products; otherwise, DISTRIBUTOR shall be responsible for
the shipping charges.

<PAGE>   6
              (c)    After the Rejection Period, DISTRIBUTOR may not return a
product to ORIGIN for any reason without  ORIGIN 's prior written consent. For
any product for which ORIGIN gives such consent, ORIGIN shall charge twenty
percent (20%) of DISTRIBUTOR's purchase price for that product and shall credit
the balance of the purchase price to DISTRIBUTOR's account within thirty (30)
days upon receipt of returned product. DISTRIBUTOR shall be responsible for all
shipping charges.

       7.     Warranty

              (a)    DISTRIBUTOR shall pass onto its customers ORIGIN's
standard limited warranty for products, including the limitations set forth in
Subsections7(b) and 7(c) below. ORIGIN warrants that its products are free from
any deficiencies for a period of twelve (12) months from the date of shipment
to DISTRIBUTOR, and will replace any deficient products free or refund the
purchase price, at ORIGIN's option during said period. This warranty is
contingent upon proper use of products in the application for which they were
intended and does not cover products that were modified without ORIGIN's
approval or that were subjected by the customer to unusual physical stress.

              (b)    EXCEPT FOR THE EXPRESS WARRANTY SET FORTH ABOVE, ORIGIN
GRANTS NO OTHER WARRANTIES, EXPRESS OR IMPLIED, BY STATUTE OR OTHERWISE,
REGARDING THE PRODUCTS, THEIR FITNESS FOR ANY PURPOSE, THEIR QUALITY, THEIR
MERCHANTABILITY, OR OTHERWISE.

              (c)    ORIGIN'S LIABILITY UNDER THE WARRANTY SHALL BE LIMITED TO
A REFUND OF THE CUSTOMER'S PURCHASE PRICE. IN NO EVENT SHALL ORIGIN BE LIABLE
FOR THE COST OF PROCUREMENT OF SUBSTITUTE GOODS BY THE CUSTOMER OR FOR ANY
SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES FOR BREACH OF WARRANTY.

       8.     Protection of Rights

              (a)    DISTRIBUTOR shall not dispute or contest or assist others
to dispute or contest the validity of any of ORIGIN's or its affiliated
companies' rights to letters patent, trademarks, copyrights, product
registrations and approvals, interest, know-how or other intangible property
concerning ORIGIN products. This covenant not to contest shall not, however,
apply to the validity of any U.S. letters patent owned by ORIGIN or to the
extent the covenant is invalid under applicable law.

              (b)    DISTRIBUTOR shall not omit or alter patent numbers, trade
names or trademarks, numbers or series, or any other ORIGIN markings affixed on
the products obtained from ORIGIN or alter product labeling without prior
written consent from ORIGIN. DISTRIBUTOR shall, however, be entitled to mark
the products with its trademark or trade name in a prominent





                                      -6-
<PAGE>   7
place, subject to ORIGIN's prior written consent. DISTRIBUTOR is not authorized
to use the trademark and trade name "ORIGIN" in any manner except to indicate,
during the term of this Agreement, that it is an independent DISTRIBUTOR for
ORIGIN and is selling ORIGIN products. DISTRIBUTOR shall acquire no rights in
the ORIGIN trademark and trade name, or any other trademark owned by ORIGIN.

              (c)    DISTRIBUTOR understands and agrees that it is not
authorized to use the name "Origin Medsystems, Inc." or "ORIGIN" in connection
with its general business or to imply to third parties that its relationship
with ORIGIN is other than as a sales DISTRIBUTOR under this Agreement.
DISTRIBUTOR shall hold ORIGIN harmless and indemnify it against any liability,
including attorneys' fees and other costs of defense, resulting from actions of
third parties claiming injury or loss as a result of the failure by DISTRIBUTOR
to honor this paragraph.

              (d)    DISTRIBUTOR agrees to protect ORIGIN's products against
imitations and unfair competition by others, and will give ORIGIN written
notice of any such conduct. DISTRIBUTOR agrees to cooperate with ORIGIN, at
ORIGIN's request and expense, and take whatever action is required to cause the
termination of such conduct. ORIGIN reserves the right to take whatever action
it deems appropriate to protect its trademarks and trade names.

              (e)    All representations of ORIGIN's trademarks that
DISTRIBUTOR intends to use shall first be submitted to ORIGIN for approval
(which shall not be unreasonably withheld) of design, color, and other details
or shall be exact copies of those used by ORIGIN. If any of ORIGIN's trademarks
are to be used in conjunction with another trademark on or in relation to
ORIGIN products, then ORIGIN's mark shall be presented equally legibly, equally
prominently, and of greater size than the other but nevertheless separated from
the other so that each appears to be a mark in its own right, distinct from the
other mark.

              (f)    ORIGIN products are offered for sale and are sold subject
in every case to the condition that such sale does not convey any license,
expressly or by implication, to manufacture, duplicate or otherwise copy or
reproduce any of ORIGIN's products. DISTRIBUTOR shall take appropriate steps
with its customers, as ORIGIN may request, to inform them of and assure
compliance with the restrictions contained in this Subsection 8(f).

       9.     Independent Contractor Relationship

              It is understood that both parties hereto are independent
contractors and engaged in the operation of their own respective businesses.
Neither party hereto is to be considered the agent of the other party for any
purpose whatsoever, and neither party has any authority, express or implied, to
enter into any contracts or assume any obligations for the other party, to
pledge the credit, or make any warranties or representations on behalf of the
other party, except where expressly authorized in writing to do so. Nothing in
this Agreement or in the activities of either party shall be deemed to create
an agency, partnership, or joint venture relationship.





                                      -7-
<PAGE>   8
       10.    Indemnity, Legal Actions, and Product Condition.

              (a)    DISTRIBUTOR agrees to save and hold ORIGIN harmless from
any and all claims, costs, liabilities and responsibilities, regardless of the
claimant or his place of  filing a claim, resulting from or in any way
associated with the functioning or performance of DISTRIBUTOR as a distributor,
supplier and seller, or other related descriptive classifications, for products
supplied to DISTRIBUTOR by ORIGIN. DISTRIBUTOR shall be the warrantor or
guarantor of the safety, operation and performance of the products covered by
this Agreement to whatever extent such a warranty or guarantee is made by
DISTRIBUTOR. The foregoing indemnity shall not extend to claims arising out of
a product defect that rendered the product unreasonably dangerous at the time
it was sold by  ORIGIN.  ORIGIN shall be responsible for any of its products
that fail to meet label specifications at the time of delivery to DISTRIBUTOR.
After delivery to DISTRIBUTOR, DISTRIBUTOR is fully responsible for any
repackaging, or re-labeling and holds ORIGIN harmless from any claims, costs,
liabilities, and responsibilities resulting in any way from any such changes
made by DISTRIBUTOR.

              (b)    DISTRIBUTOR agrees not to join ORIGIN or any ORIGIN
employee as a party defendant or plaintiff, or any interest thereof, in any
action at law or in equity or in any other proceeding, regardless of the
descriptive classification, arising out of the liabilities, duties and
responsibilities above described which DISTRIBUTOR assumes or performs.
DISTRIBUTOR shall promptly notify ORIGIN of any and all actions at law or
equity or claims or governmental administrative proceeding arising out of the
operation or performance of this Agreement.

              (c)    ORIGIN warrants that all products are in operating
condition at the time of shipment. Nothing herein shall relieve ORIGIN of any
obligation or liability existing under applicable law regarding claimed defects
in the products supplied to DISTRIBUTOR by ORIGIN, provided that (i) such
defect existed at the time the product was shipped by ORIGIN; (ii) no
modifications in design have been made by or with the approval of DISTRIBUTOR
or by the customer which affect the stability or reliability of the product;
(iii) the product has not been subject to misuse, negligence or accident; (iv)
the instrument has not had the serial or lot number altered, effaced or
removed; (v) the instrument has been used in accordance with its instructions
for use; (vi) the Product has been packed for shipment to final customer in
such a way as to protect sterility and functionality of Product; and (vii) any
re-labeling done by distributor does not physically cover required information,
and was applied correctly according to all applicable laws and regulations.

       11.    Inability to Deliver.

              (a)    Nonperformance of either party shall be excused to the
extent that performance is rendered impossible due to industrial conflicts,
mobilization, requisition, embargo, currency restriction, insurrection, general
shortage of transport, material or power supply, fire, explosion, stroke of
lightning, force majeure and similar casualties or other events beyond ORIGIN's
control, as well as default in deliveries from subcontractors due to such
circumstances as defined in this clause.





                                      -8-
<PAGE>   9
              (b)    If the performance of this Agreement by either party is
made commercially impracticable (i) by the occurrence of an economic
contingency the non-occurrence of which was a basic assumption oil which this
Agreement was made or (ii) by compliance in good faith with any applicable
foreign or domestic governmental law, regulation, or order, then this Agreement
shall terminate immediately. For purposes of this Agreement, currency
devaluation, currency restrictions, currency and exchange controls, and other
monetary controls, restrictions, and restraints shall not be considered to
render the performance of this Agreement by DISTRIBUTOR commercially
impracticable, or otherwise be considered force majeure with respect to
DISTRIBUTOR.

       12.    Proprietary Information

              DISTRIBUTOR acknowledges that it has access to valuable ORIGIN
proprietary information, including but not limited to, technical data and
customer and marketing information, all of which are the property of ORIGIN,
have been maintained confidential, and are used in the course of ORIGIN's
business. DISTRIBUTOR shall not, either during the term of this Agreement or
thereafter, disclose such ORIGIN proprietary information to anyone other than
those of its employees having a need to know and shall refrain from use of such
information other than in the performance of this Agreement. In addition,
DISTRIBUTOR shall take all reasonable precautions to protect the value and
confidentiality of such information to ORIGIN. All records, files, notes,
drawings, prints, samples, advertising material and the like relating to the
business, products or projects of ORIGIN, and all copies made from such
documents, shall remain the sole and exclusive property of ORIGIN and shall be
returned to ORIGIN immediately upon written request by ORIGIN. DISTRIBUTOR
agrees to continue to maintain all proprietary information confidential and to
refrain from using such proprietary information in any future manufacturing or
marketing operations anywhere in the world for a period of five (5) years
following termination of this Agreement, unless written authorization to do so
is first obtained from ORIGIN. Neither party shall be obligated or required to
maintain in confidence any information which it can demonstrate with written
records (i) is in the public domain or known to the receiving party prior to
disclosure by the disclosing party; or (ii) becomes known to the public after
disclosure by the disclosing party, other than through breach of this
Agreement; or (iii) becomes known to the receiving party from a source other
than the disclosing party without breach of any obligation of confidence; or
(iv) is or has been furnished to a third party by the disclosing party without
restriction on the third party's right to disclose.

       13.    Government Regulations

              DISTRIBUTOR agrees that it shall not allow either the products
supplied to it by ORIGIN, ORIGIN's trademarks, any proprietary data of ORIGIN,
or any direct product of such data, to be knowingly made available, either
directly or indirectly, or in any way to be knowingly given, transferred, sold
or reexported to any country in violation of its laws and export control
regulations or applicable laws of any country (or the European Economic
Community). United States laws and





                                      -9-
<PAGE>   10
export control regulations governing the exportability of technical data and
products to nations are subject to change.

              DISTRIBUTOR will promptly notify ORIGIN by phone or in writing if
any of its end users notify DISTRIBUTOR that any ORIGIN products are found by
such end-users, upon incoming inspection, to be defective or to fail to meet
applicable specifications. If such notification is by phone DISTRIBUTOR shall
follow-up with a confirmation in writing. If any of DISTRIBUTOR's customers
notify DISTRIBUTOR of an alleged failure in the performance of the products,
DISTRIBUTOR will notify ORIGIN in writing, in reasonable detail, promptly, but
no later than twenty-four (24) hours after DISTRIBUTOR's receipt of such
complaint, describing the particulars of the complaint.

              If either DISTRIBUTOR receives a complaint, oral or written,
regarding any of the ORIGIN products, it will notify ORIGIN, in writing and in
reasonable detail of such complaint as soon as is practicable, but in no event
later than three days after its receipt of the complaint, and will provide all
information necessary for ORIGIN to comply with any applicable regulatory and
legal requirements. ORIGIN will be responsible for evaluating in detail all
customer complaints that relate to any ORIGIN products.

              If ORIGIN desires to undertake a recall of any product, ORIGIN
will immediately notify the DISTRIBUTOR, and the parties will promptly discuss
such recall, with such notification and discussion being made prior to any
recall, to the extent permitted, in ORIGIN's judgment, by any applicable legal
or safety constraints. DISTRIBUTOR will maintain complete and accurate records,
for such periods as may be required by applicable law, of all products sold by
it, and will provide access to such records to the extent necessary to
effectuate any recall. DISTRIBUTOR will cooperate with ORIGIN as to the
initiation and conduct of any recall, including communications with any
purchasers and end-users and any applicable regulatory authorities.

       14.    Unfair Competition and Patent Infringement

              (a)    DISTRIBUTOR shall promptly advise ORIGIN of any
infringement or potential infringement by third parties of which DISTRIBUTOR
becomes aware of any issued patents relating to the products supplied by ORIGIN
under this is Agreement. ORIGIN shall have the right, but not the obligation,
to sue alleged infringers. If suit is brought by  ORIGIN , ORIGIN shall control
the prosecution thereof and be entitled to retain any amounts recovered in full
by reason of such infringement. DISTRIBUTOR agrees to cooperate with and assist
ORIGIN in any such suit. ORIGIN shall reimburse DISTRIBUTOR for costs related
to such assistance. ORIGIN shall have the exclusive right to negotiate and
approve any settlement of such suits.

              (b)    In the event that DISTRIBUTOR joins ORIGIN by mutual
agreement in litigation relating to such infringement, DISTRIBUTOR shall bear
an agreed proportion of the legal costs. Should any damages or costs in such
litigation be awarded to ORIGIN and DISTRIBUTOR,





                                      -10-
<PAGE>   11
DISTRIBUTOR shall be entitled to recover the same proportion thereof as its
contribution to expenses.

              (c)    ORIGIN represents that it has no knowledge of any patent
rights that would be infringed by use or sale of ORIGIN products in the Primary
Area of Responsibility, or use of its proprietary in formation, but ORIGIN does
not warrant that the manufacture, use or sale of any of its products, or
utilization of any of its proprietary information, is free of liability for
infringement or charges of infringement of patent rights owned by third
