Expansion of Territory.

Pharmanetics will promptly advise Bayer in writing of opportunities for
extension of Bayer's distribution rights into any country outside the Territory
in which Pharmanetics desires to expand or any country where existing rights
lapse or are subject to competitive bid or in any country in which Pharmanetics
currently has a distribution agreement, in each case where Bayer has a
distribution network in place. Pharmanetics agrees not to enter into any
contract for distribution rights in such other country until the earlier of the
receipt of a proposal from Bayer regarding such country or the expiration of the
ninety (90) day period following Bayer's receipt of written notification
pursuant to this sub-section. In considering the award of any expansion
territory, the parties hereto agree to consider the relationship of Pharmanetics
and Bayer and Bayer's performance hereunder as a criteria in making any such
award. Nothing in this sub-section shall limit the rights of Pharmanetics to
solicit, review or negotiate with any party at any time with respect to areas
outside the Territory as the same may exist from time to time.

Notwithstanding the foregoing, if Pharmanetics determines to enter into any
agreement or significant negotiations with a third party granting distribution
rights to such party with respect to (i) Specialty Products in the United States
or Canada or (ii) Products in the Home Market, Pharmanetics will promptly advise
Bayer in writing prior to entering into any such negotiations or agreement
granting any such distribution rights to a third party. Pharmanetics agrees not
to enter into a distribution agreement for (i) Specialty Products in the United
States or Canada or (ii) Products in the Home Market until the earlier of the
receipt of a proposal from Bayer regarding such rights or the expiration of the
ninety (90) day period following Bayer's receipt of written notification
pursuant to this sub-section. In considering the award of any such rights,
Pharmanetics agrees to consider the relationship of Pharmanetics and Bayer and

rights. Nothing in this Sub-section shall limit the rights of Pharmanetics to
solicit, review or negotiate with any party at any time with respect to such
distribution rights. The provisions of this subparagraph relating to Bayer's
opportunity to gain distribution rights in the Home Market shall not be
available to Bayer if Bayer determines to enter any agreement with a third party
relating to the Home Market or if Bayer enters into significant negotiations
with a third party regarding the Home Market if such third party is not
Pharmanetics. Bayer shall discuss with Pharmanetics its plans regarding the Home
Market prior to entering the Home Market and prior to entering into an agreement
with a third party relating to the sale of products to the Home Market.

Pharmanetics will use its best efforts to facilitate and aid Bayer's
negotiations with Tokuyama Soda Company, Ltd., (excluding the payment of any
money) regarding distribution of Pharmanetics PT and aPTT cards in Japan, Korea
and Taiwan.

Pharmanetics and Bayer jointly developed and agreed to a worldwide distributor
transition plan to provide for granting distributor relationships in favor of
Bayer as and when permitted under any such existing distribution agreements.

Pharmanetics hereby grants Bayer the non-exclusive right to process orders for
the Specialty Products within the United States and Canada in the Specified
Markets pursuant to the terms and conditions of this Section 2.8. Pharmanetics

the marketing of the Specialty Products in the United States and Canada.
Pharmanetics, at its expense, shall provide Bayer with reasonable quantities of

Pursuant to the terms and conditions of this Section 2.8, Bayer shall process
orders placed with Pharmanetics and received by Bayer directly from a
prospective customer for Specialty Products to be sold by Pharmanetics in the
United States or Canada (a "Specialty Product Order").

Immediately upon receipt of a Specialty Product Order (as defined below), Bayer

Order, including the name and address of the customer, the Specialty Product to
be purchased by such customer, delivery dates and delivery instructions. Upon
Pharmanetics receipt of such information, Pharmanetics will provide Bayer with

Within one business day of Bayer's receipt of a Specialty Product Order Purchase
Price, Bayer will perform a credit check on the customer referred to in the
Specialty Product Order, and if Bayer at Bayer's reasonable discretion approves
such customer, then Bayer shall promptly request in writing that Pharmanetics
deliver to the Customer the Specialty Product(s) referred to in the Specialty
Product Order (an "Approved Specialty Product Order"). With respect to each
Approved Specialty Product Order, Bayer shall assume all responsibility for
billing the customer and collecting from the customer. In the event Bayer
rejects a Specialty Product Order, it shall promptly notify Pharmanetics of the
same in writing and Pharmanetics shall be permitted to process the rejected
Specialty Product Order.

Pharmanetics shall use its best efforts to deliver the Specialty Products
ordered by the customer in accordance with the delivery schedule and in the
quantities specified in the Approved Specialty Product Order. At no time shall
title to Specialty Products delivered pursuant to this Section 2.8(d) pass to

For each Specialty Product delivered to a Customer pursuant to this Section 2.8,
Bayer shall pay Pharmanetics an amount as set forth in Schedule 2.8. Such
amounts shall be due and payable seventy (70) days from date of invoice. The
failure of Bayer to collect any amounts due pursuant to any Approved Specialty
Product Order shall in no way affect amounts due to Pharmanetics, provided
however, that Bayer may deduct amounts customers refuse to pay for reasons
related to Product defects.

Pharmanetics shall be responsible for providing technical support to customers
of Specialty Products delivered pursuant to an Approved Specialty Product Order.

The provisions of this Section 2.8 shall in no way be deemed to restrict the
ability of Pharmanetics to provide Specialty Products to collaborative partners
and other entities participating in such collaborations and such Specialty
Products in the United States and Canada.

action. Pharmanetics and Bayer will review any recommendation and agree to the
appropriateness of the corrective action prior to its initiation and the

                                       13
<PAGE>

notification of any affected customers. However, in the event the parties cannot
agree on the corrective action, the party having responsibility for the
corrective action may act at its discretion. Bayer will provide notice to its
customers of the required corrective action for the Products. Upon determination
of the party responsible for the recall or Field Corrective Action, such party
shall be responsible for the cost of notifying end users and for determining the
corrective actions to be taken and the costs associated with such actions.
Pharmanetics and Bayer shall fully cooperate with one another and provide all
reasonable assistance in conducting any recall or Field Corrective Action under
this Paragraph. Bayer shall maintain records of all sales of the Products
sufficient to carry out a recall with respect to Products purchased under the
Agreement. If the recall meets the definition of corrective action and removal,
and constitutes a risk to health, as defined by 21 CFR 806, corrective action
shall be carried out in accordance with regulations including reporting to the
FDA or under Vigilance reporting to the European Union competent authority and
other applicable regulatory agencies.

General Obligations of Pharmanetics and Bayer.

Except as otherwise expressly provided in the Agreement, Pharmanetics shall
manufacture, test, package, and label the Products pursuant to the terms,
conditions and subject to the limitation contained in this Agreement. Bayer
shall price, invoice and have shipped in the Territory or in the Specified
Markets, all Products pursuant to the terms, conditions and subject to the
limitations contained in this Agreement.

Pharmanetics shall manufacture, test, package, label and release and Bayer shall
maintain, store and ship the Products in accordance with all applicable GMP

Products from the market; (4) any regulatory comments relating to the
manufacture of the Products requiring a response or action by either party.

Pharmanetics shall maintain all manufacturing and analytical records, all
records of shipments of the Products from Pharmanetics, and all validation data

or otherwise as required by applicable law.

Forecasts.  Beginning with the execution hereof, Bayer shall provide monthly, by
the fifteenth day of each month, its estimated  forecast of its requirements for
the  Products for each of the six (6) months  following  the end of the month in

                                       14

which such forecast is submitted (each a "Forecast"). All Forecasts under this
Agreement and updates thereof for any period will constitute a firm obligation
of Bayer to purchase the quantities of Products indicated for the first three
months of such Forecast.

Delivery. Pharmanetics shall use its best efforts to supply the Products ordered
by Bayer and shall supply Products in accordance with the delivery schedule and
in the quantities specified by Bayer provided; however, Pharmanetics shall not
be obligated to deliver Products to the extent that orders for such Products

contains the firm obligation of Bayer to purchase Products. Pharmanetics
shipments of Products shall be delivered FOB freight collect Pharmanetics's
distribution site, Raleigh, North Carolina, to Bayer's carrier at which time
title, ownership and risk of loss and damage shall pass to Bayer. Pharmanetics
shall deliver Products, properly packed for distribution (including, but not
limited to refrigerated distribution), to the carrier selected by Bayer at its
distribution site. All freight and insurance expenses, as well as any special
handling or special packing expenses requested by Bayer, shall be paid by Bayer.
(Packing for refrigerated distribution is not a special packing expense.) Bayer
shall bear any and all applicable taxes, duties and similar charges that may be
assessed against the Products after delivery to the carrier at Pharmanetics's
distribution site. Pharmanetics shall include shipping documents with Products
in accordance with Bayer's reasonable requests.

Acceptance of Products. Pharmanetics shall test each newly manufactured lot of
Products for conformance with the applicable Release Criteria. Each lot meeting
such Release Criteria shall be deemed accepted and Pharmanetics shall complete
and forward to Bayer a certificate of analysis for such lot in a form based upon
the Release Criteria and mutually agreed by the parties.

Packaging. All labels and labeling produced by Pharmanetics for Products,
including packaging layout, design and color, shall be consistent with artwork
supplied or approved by Bayer. Pharmanetics shall provide all necessary labels
and package inserts for all Products, as well as for the shipping container,
which labels and package inserts shall comply with applicable label and labeling
requirements of the FDA and other regulatory agencies, including the labeling
requirements of the IVDD. Bayer shall not use any other labels or package
inserts for any of such Products.

Taxes; Duties. The actual amount of sales, use, excise, value-added and similar
taxes levied upon or applicable to the transfer of Products to Bayer are payable
by Bayer. Bayer and its Affiliates shall pay all duties, tariffs, surcharges and
other customs and other governmental fees levied in connection with the export
of Products outside of the United States but within the Territory.

Quality. The parties shall in connection with the quarterly meetings required
under Section 3.1 cooperate to develop and implement a quality plan designed to
minimize or eliminate Product defects and provide for continuous improvement in
Product quality.

Product Warranty.

Standard Limited Warranty. Pharmanetics warrants that the Routine Products, New

package inserts approved by Pharmanetics; (c) will not be products that are
adulterated or misbranded within the meaning of the Act; (d) shall have been
manufactured, packaged, stored and shipped in conformity with applicable GMP
requirements; and (e) will not be products that may not be introduced into
interstate commerce pursuant to applicable federal or state law.

               Pharmanetics warrants that all Instruments and Accent Instruments
          shall, until the earlier of twenty-four (24) months from shipment by
          Pharmanetics or twelve (12) months after the date of installation with
          the customer: (a) conform to the Instrument and Accent Instrument
          Specifications, as applicable; (b) comply with the requirements of the
          Act, if applicable, and shall conform to the labeling and package
          inserts approved by Pharmanetics; (c) will not be products that are
          adulterated or misbranded within the meaning of the Act; (d) shall

          may not be introduced into interstate commerce pursuant to applicable
          federal or state law.

               This limited warranty is contingent upon proper use of a Product
          in the application for which such Product was intended and does not
          cover Products that were modified without Pharmanetics's written
          approval, that have expired, or that were improperly stored or
          handled. Except as set forth in Schedule 6.1(b), as of the date of the
          execution of this Agreement, Pharmanetics has no knowledge that any of
          the Products, or the sale or use of any of the Products for their
          intended purposes infringe any intellectual property of any third
          party.

No Other Warranty. EXCEPT FOR THE EXPRESS LIMITED WARRANTIES SET FORTH IN
SECTION 6.1 ABOVE, PHARMANETICS GRANTS NO WARRANTIES FOR THE PRODUCTS, EXPRESS
OR IMPLIED, EITHER IN FACT OR BY OPERATION OF LAW, BY STATUTE OR OTHERWISE, AND
PHARMANETICS SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTY OF QUALITY, WARRANTY OF
MERCHANTABILITY, WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE OR WARRANTY OF
NON-INFRINGEMENT.

Remedy  and  Limitation  of  Liability.  EXCEPT AS  OTHERWISE  PROVIDED  HEREIN,
PHARMANETICS'S LIABILITY AND BAYER AND ITS AFFILIATES,  ITS DISTRIBUTORS AND ITS
CUSTOMERS  SOLE REMEDY UNDER THE LIMITED  WARRANTY  UNDER  ARTICLE 6 HEREOF WITH
RESPECT TO ANY  PRODUCTS  SHALL BE  LIMITED  TO A REFUND OF BAYER'S  COST OF THE
PRODUCTS  OR  REPAIR  OR  REPLACEMENT,  IN ALL  EVENTS  AT  PHARMANETICS'S  SOLE
DISCRETION.  EXCEPT AS OTHERWISE PROVIDED HEREIN, IN NO EVENT SHALL PHARMANETICS

                                       16
<PAGE>

BE LIABLE FOR THE COST OF PROCUREMENT OF SUBSTITUTE PRODUCT OR FOR ANY-SPECIAL,
CONSEQUENTIAL OR INCIDENTAL DAMAGES FOR BREACH OF WARRANTY OR OTHERWISE.
PHARMANETICS SHALL BEAR THE EXPENSE OF FREIGHT FOR ALL RETURNED GOODS.

Card Dating. Pharmanetics guarantees to deliver all Routine Products within
three (3) months of the date of manufacture and with a minimum of nine (9)
months dating at the time of such delivery. Specialty Products delivered to
Bayer pursuant to Section 2.8 shall be shipped into Bayer inventory with 9
months dating.

Assertion of Claims. In any case where Bayer expects to make a claim against
Pharmanetics with respect to nonconforming Product, Bayer shall retain the
Product for the lesser of thirty (30) days or receipt of written authorization
and instructions of Pharmanetics either to dispose of the Product or to return
the Product to Pharmanetics. Bayer will provide Pharmanetics proof of
destruction of cards when requested by Pharmanetics.

Year 2000 Compliance. Subject to the limitations set forth in this Article 6,
Pharmanetics certifies to Bayer that all Products are year 2000-compliant.

Payments for Product.

Purchase Price. Payments for Product shall be made in accordance with Schedule
7.

Adjustments to the Purchase  Price.  The Card Purchase Price shall be subject to
adjustment as set forth in Schedule 7.

Failure of Efforts Maintain Distribution Rights. Notwithstanding anything to the
contrary in this Agreement, at any time upon sixty (60) days' written notice
where Bayer fails to (i) use commercially reasonable efforts to sell Products in
any country within the Territory, or (ii) maintain a distribution network or
other sales presence in any country within the Territory other than the United
States and Canada, and such failure persists beyond such sixty (60) day period,
Pharmanetics shall be entitled to terminate this Agreement with respect to the
grant of distribution rights for that specific country.

Payment. All Pharmanetics invoices shall be paid net 30 days from date of
invoice in US Dollars; provided, however, that if a customer will only accept a
single lot of material over an extended period of time, payment for such
Pharmanetics invoices shall be paid net sixty (60) days from date of
Pharmanetics's invoice in US Dollars. Bayer shall provide Pharmanetics with
documentation of such arrangements. Any invoiced amounts not paid when due shall
be subject to a service charge at the lower of the rate of one and one-half
(1.5%) percent per month or the maximum rate permitted by law. If Bayer fails to
make any payment to Pharmanetics when due, Pharmanetics shall give Bayer written
notice of such non-payment and Bayer shall have ten (10) days from the receipt
of such notice to make the payment. Pharmanetics may upon thirty (30) days

                                       17
<PAGE>

written notice to Bayer without affecting any other rights under this Agreement,
terminate this Agreement or cancel or delay shipments hereunder to Bayer for
non-payment by Bayer after such ten (10) day period.

Confidentiality.

"Proprietary Information" means: all financial information, marketing
information, sales information, customer information, raw materials, know-how,
drawings, compositions, manufacturing and other specifications, analytical
procedures, flow sheets, reports, market studies, preclinical and clinical test
results, FDA and other regulatory submissions, software and other medical,
research, technical, and marketing information disclosed, directly or
indirectly, by either party or any of its Affiliates to the other party,
retroactively to December 17, 1997, in writing, marked "Confidential",
"Proprietary" or the like, or, if transmitted orally or by observation of
equipment or other material, confirmed by a writing so marked within sixty (60)
days of its disclosure, or which by its nature is information normally intended
to be held in confidence, unless the same: (a) is or becomes public knowledge
through no fault of the receiving party; (b) is legally in the possession of the
receiving party prior to receipt from the disclosing party; (c) is subsequently
and lawfully received from a third party without its breach of any nondisclosure
obligation; (d) is independently developed by employees of the receiving party
who have had no access to the Proprietary Information of the disclosing party;
or (e) is required to be disclosed by order of a court or administrative agency,
provided that in such event the party that is subject to the required disclosure
furnish the other party with adequate notice. Notwithstanding the immediately
preceding sentence, Pharmanetics agrees that all new materials and other
information which Bayer provided to Pharmanetics prior to December 17, 1997,
shall be treated as Proprietary Information.

Non-Disclosure. During the duration of this Agreement and for a period of five
(5) years thereafter, neither party shall disclose to third parties, or use for
its benefit, in whole or in part, any Proprietary Information received from
other party, except to the extent required to comply with the Act or other laws.
Each party shall take all reasonable steps to minimize the risk of disclosure of
Proprietary Information, including, without limitation:

ensuring that only its employees whose duties require them to possess such
information have access thereto; and

exercising at least the same degree of care that it uses for its own Proprietary
Information.

Duties Upon Termination. Except as otherwise permitted under this Agreement,
upon request by the disclosing party after expiration or termination of this
Agreement, the other party shall either return all of such disclosing party's
Proprietary Information (including data, memoranda, drawings and other writings
and tapes and all copies thereof) received or prepared by it or destroy the
same, and in any event shall make no further use of such Proprietary Information

                                       18
<PAGE>

at any time provided, however, that counsel for the receiving party may keep one
copy of the Proprietary Information for purposes of ascertaining the receiving
party's obligations pursuant to this Section 8.

Use of Proprietary Information. During the duration of this Agreement and for a
period of five (5) years thereafter, neither party shall use the other party's
Proprietary Information for any purposes, except to perform its obligations
hereunder. In no event shall Bayer use any Proprietary Information for
commercial purposes subsequent to the termination of this Agreement.

Injunctive Relief. Each party acknowledges that the other party would not have
an adequate remedy at law for breach of any of the covenants contained in this
Section 8 and hereby consents to the enforcement of same by the other party by
means of temporary or permanent injunction issued by any court having
jurisdiction thereof and further agrees that the other party shall be entitled
to assert any claim it may have for damages resulting from the breach of such
covenants in addition to seeking injunctive or other relief. The provisions of
this Agreement relating to Proprietary Information shall supercede any prior
agreements relating to Proprietary Information between Bayer and Pharmanetics.

Indemnification.

Indemnification by Pharmanetics. Subject to Bayer's compliance with its
obligations set forth in Section 9.3 below, Pharmanetics shall indemnify, defend
and hold Bayer, its Affiliates, subdistributors, their directors, officers,
employees and agents harmless from and against any and all losses, damages,
liabilities, claims, demands, judgments, settlements, costs and expenses
(including, without limitation, reasonable attorneys' fees and other costs of
defense) (collectively "Losses") attributable to, or arising out of a breach by
Pharmanetics of any of Pharmanetics's warranties, representations, covenants or
obligations hereunder or any claim, lawsuit or other action by a third party
for, breach of contract, personal injury or property damage to the extent caused
by a breach by Pharmanetics of this Agreement, or out of or connected with the
use or sale of the Product to the extent directly caused by Pharmanetics's
fault, negligence or breach of any of its obligations hereunder concerning the
use or sale of the Product.

Indemnification by Bayer. Subject to Bayer's compliance with its obligations set
forth in Section 9.3 below, Bayer shall indemnify, defend and hold Pharmanetics
and its Affiliates, their shareholders, directors, officers, employees and
agents harmless from and against any and all Losses attributable to, or arising
out of a breach by Bayer of any of Bayer's warranties, representations,
covenants or obligations hereunder, or any claim, lawsuit or other action by a
third party for, breach of contract, personal injury or property damage to the
extent caused by a breach by Bayer or any of its Affiliates of this Agreement,
or out of or connected with the use or sale of the Product to the extent
directly caused by Bayer's fault, negligence or breach of any its obligations
hereunder concerning the use or sale of the Product.

Notice  and  Assistance.  A party  (the  "indemnitee")  which  intends  to claim
indemnification  under this Section 9 shall promptly notify the other party (the

                                       19
<PAGE>

"indemnitor") in writing of any action, claim or other matter in respect of
which the indemnitee or any of its employees or agents intend to claim such
indemnification. The indemnitee shall permit, and shall cause its employees and
agents to permit, the indemnitor, at its discretion, to settle any such action,
claim or other matter and agrees to the complete control of such defense or
settlement by the indemnitor; provided, however, that such settlement does not
adversely affect the indemnitee's rights hereunder or impose any obligations on
the indemnitee in addition to those set forth herein in order for it to exercise
such rights. No such action, claim or other matter shall be settled without the
prior written consent of the indemnitor and the indemnitor shall not be
responsible for any legal fees or other costs incurred other than as provided
herein. At the expense of the indemnitor, the indemnitee shall render the
indemnitor all assistance reasonably necessary in defending against such claim,
suit, or action. The indemnitee party shall have the right at its expense, to
retain separate counsel to act in an advisory capacity in connection with any
matter involving a claim for indemnity and the indemnitor will cooperate with
such counsel.

Patents.

Ownership. Except as provided herein with respect to trademarks, Bayer
acknowledges that it does not have, nor does it hereby acquire, any right, title
and interest in and to any patents, patent applications, trademarks or other
proprietary rights of Pharmanetics owned by Pharmanetics at the time of the
execution of this Agreement. Except as provided herein with respect to
trademarks, Pharmanetics acknowledges that it does not have, nor does it hereby
acquire, any right, title and interest in and to any patents, patent
applications, trademarks or other proprietary rights of Bayer owned by Bayer at
the time of the execution of this Agreement.

Patent Infringement.

Defense. Bayer agrees that Pharmanetics has the right to defend or at
Pharmanetics's option to settle, and Pharmanetics agrees at Pharmanetics's
expense, to defend or at Pharmanetics's option to settle, each claim, suit or
proceeding brought against Bayer or Bayer's customers arising out of or related
to an allegation of infringement of any United States patent, copyright, or
trademark or misappropriation of trade secrets by the sale of Products sold
hereunder or the use thereof, subject to the limitations hereinafter set forth.
Pharmanetics shall have sole control of any such action or settlement
negotiations, and Pharmanetics agrees to pay, subject to the limitations
hereinafter set forth, any final judgment (including all prejudgment and
post-judgment interest) entered against Bayer or Bayer's customers on such issue
in any such suit or proceeding defended by Pharmanetics. Bayer agrees that
Pharmanetics at Pharmanetics's sole option, shall be relieved of the foregoing
obligations unless Bayer shall notify Pharmanetics promptly in writing following
receipt of service of process or any other direct communication from the party
bringing a claim, suit or proceeding of such claim, suit or proceeding and give
Pharmanetics authority to proceed as contemplated herein, and at Pharmanetics's
expense, cooperates with Pharmanetics to settle and/or defend any such claim,
suit or proceeding. Pharmanetics shall not be liable for any costs or expenses
incurred without Pharmanetics's written authorization.

                                       20
<PAGE>

Limitation. Notwithstanding the provisions of subsection 10.2(a) above,
Pharmanetics assumes no liability for (i) infringements covering completed
Products when used in combination with another product or products or any
composition, assembly, combination method or process in which any of the
Products may be used in combination with another product or products; provided,
however, that such limitation shall not apply where the sale or use of the
Product (whether or not in any composition, assembly, combination, method or
process) is a sale for a use or a use intended or approved by Pharmanetics; (ii)
infringements involving any marking or branding not applied by Pharmanetics or
applied at the request of Bayer; or (iii) infringements involving the
modification or servicing of the Products, or any part thereof unless such
modification or servicing was performed by Pharmanetics or in accordance with
Pharmanetics's written instructions or approved by Pharmanetics.

THE FOREGOING PROVISIONS OF THIS SECTION 10.2 STATE THE ENTIRE LIABILITY AND
OBLIGATION OF PHARMANETICS AND THE EXCLUSIVE REMEDY OF BAYER, ITS AFFILIATES,
DISTRIBUTORS AND CUSTOMERS WITH RESPECT TO ANY ALLEGED INFRINGEMENT OF PATENTS,
COPYRIGHTS, TRADEMARKS, OR OTHER INTELLECTUAL PROPERTY RIGHTS BY THE PRODUCTS OR
ANY PART THEREOF.

Patent Enforcement. If Bayer believes that a third party is reasonably likely
infringing Pharmanetics's patent rights in the Territory, Bayer shall promptly
notify Pharmanetics of that fact and shall provide to Pharmanetics reasonable
evidence of any such claim based upon materials available to Bayer. Upon receipt
of evidence satisfactory to Pharmanetics of infringement, in Pharmanetics's sole
discretion Pharmanetics shall then have the sole right to take action against
such infringing third party. If Pharmanetics fails to take commercially
reasonable action within two (2)months to stop such infringement, and such
infringement, if allowed to continue, would have a substantial effect on Bayer's
sales of the Product, Bayer shall then be entitled to take commercially
reasonable action to stop such infringement, including the filing of suit;
provided, that Bayer shall not have such right so long as Pharmanetics is then
diligently taking action against at least one infringing third party in at least
one country in the Territory. If Bayer chooses to take such commercially
reasonable action, Pharmanetics shall cooperate with Bayer to enable Bayer to
take such action and Bayer shall have sole control over any lawsuit or
settlement. For purposes of this Section 10.2(d), "commercially reasonable
action" requires at a minimum advising the infringing party to cease and desist
its infringement. For purposes of this Section 10.2(d), "substantial effect on
Bayer's sales of the Product" means a third party offering for sale the Product
or an equivalent of the Product. For purposes of this Section 10.2(d),
"diligently taking action" means that Pharmanetics has filed at least one patent
infringement lawsuit against at least one infringer in at least one country. Any
recovery of damages or settlement amounts from any court actions or out of court
actions shall be divided as follows: one hundred percent to cover costs of the
parties until expenses are reimbursed in full and thereafter seventy five
percent to Pharmanetics and twenty-five percent to Bayer. Pharmanetics shall
have the right to settle any such action. Bayer shall have the right to
renegotiate its minimum performance obligations under Section 7.3 to the extent
they may be affected by such third party sales of the Product(s) in the
Territory.

                                       21
<PAGE>

Cooperation. If either party takes action against a third party pursuant to this
Section 10.2, or if a third party claims the manufacture, use or sale of Product
in the Territory infringes its patent or other proprietary rights, the other
party agrees to provide reasonable assistance by supplying information within
its control which may assist the party taking the enforcement action or
defending such claim.

Distribution Rights. Pharmanetics hereby grants to Bayer the right to act as its
authorized distributor in the Territory to use and sell the Products for the
term of this Agreement. During the term of this Agreement Pharmanetics shall not
bring any claim or action against Bayer or any of its Affiliates for the
infringement or misappropriation of any intellectual property owned or licensed
to Pharmanetics based upon the use or sale by Bayer or any of its Affiliates of
Products pursuant to the terms and conditions of this Agreement.

Term; Termination.

Term. The initial term of this Agreement shall be from the Effective Date until
December 31, 2003, unless terminated earlier under the provisions of this
Agreement. The parties intend to renew this Agreement at the end of each
five-year period (subject to the parties' renegotiation in good faith of minimum
purchase and price provisions) unless at least one hundred eighty (180) days
prior to the end of any five year term, either party provides to the other
written notice of its intent to terminate.

Termination for Cause - Either Party. Without prejudice to any other rights it
may have hereunder or at law or in equity, either party may terminate this
Agreement immediately by written notice to the other party upon the occurrence
of any of the following:

the other party becomes insolvent, an order for relief is entered against the
other party under any bankruptcy or insolvency laws or laws of similar import;

the other party makes an assignment for the benefit of its creditors or a
receiver or custodian is appointed for it or its business is placed under
attachment, garnishment or other process involving a significant portion of its
business;

after sixty (60) days' written notice from the terminating party without cure by
the other party of any material breach of this Agreement by the other party not
involving minimum sales or payments;

the  failure by Bayer to make any payment  due under this  Agreement  consistent
with the terms contained in Section 7.2;

the failure by Bayer to maintain  sales to end users as set forth in sub-section
7.3;

after sixty (60) days written notice from Pharmanetics, without cure by Bayer,
in the event of the sale of products by a distributor appointed by Bayer in the
Territory which are competitive with the Products; or

                                       22
<PAGE>

the "change of control" of Pharmanetics. Change of control of Pharmanetics shall
be defined as (i) the merger or consolidation of Pharmanetics with a third party
where Pharmanetics is not the surviving entity or (ii) the sale of all or
substantially all of Pharmanetics's assets or (iii) the sale or transfer of all
or substantially all of Pharmanetics's rights related to the manufacture and
sale of products in Pharmanetics's Routine Product or Specialty Product
division, provided, however, Pharmanetics may not terminate this Agreement for
this cause prior to December 31, 2002.

The "change of control" of Bayer where Bayer or the successor entity, as the
case may be, competes with Pharmanetics with respect to rapid diagnostic testing
of hemostasis in the Territory in the Specified Markets. For purposes of this
Section 11.2(h), "change of control" of Bayer shall have the meaning set forth
in Section 10.1(d) of the Common Stock Purchase Agreement between Bayer and
Pharmanetics, dated as of the date hereof.

Rights and Duties Upon Termination.

Termination of this Agreement, for whatever reason, shall not affect any rights
or obligations accrued by either party prior to the effective date of
termination, including under any purchase order for Products placed prior to the
effective date of termination.

Except as provided otherwise in this Section 11.3, upon termination of this
Agreement, Pharmanetics shall use reasonable efforts to continue to sell and
supply Products to Bayer and its Affiliates in such quantities as ordered but in
quantities no greater than reasonably appropriate in connection with fulfilling
contractual commitments to customers of Bayer, its Affiliates and its
subdistributors for a period not to exceed twelve (12) months; provided,
however, that such customers are end-user customers that purchased Products
during the six (6) months immediately prior to the termination of this
Agreement. Prices for Products shall remain at the level of the immediately
prior year adjusted solely for increases/decreases in material, labor, and
reasonable overhead; provided, however, that if the termination of this
Agreement does not relate to Section 11.2(c) or Section 11.2(d) or Section
11.2(e), any such price increases shall be limited to increases in the Producer
Price Index over the index for the year prior to any such termination. Upon
termination of this Agreement, and to the extent permitted under applicable law,
in each and every case for a price paid by Pharmanetics equal to the cost and
expense incurred by Bayer and its Affiliates to obtain such approvals and
registrations, Bayer, upon Pharmanetics's request, shall assign to Pharmanetics
(or such other entities designated by Pharmanetics) all product approvals,
registrations and regulatory approvals to sell Products in each country in the
Territory; or, if assignment of any such registration or approval is not
permissible under applicable law, where requested by Pharmanetics, Bayer shall
grant Pharmanetics (or its designee) a right of reference to such registrations
and approvals. Bayer shall otherwise use reasonable efforts to enable
Pharmanetics to import and sell the Products in such countries.

Upon termination of this Agreement by Bayer, Pharmanetics will not sell cards
bearing Bayer marks except to Bayer.

Sections of this Agreement shall survive any termination of this Agreement which
relate to confidentiality and indemnification, or otherwise which by their
nature cannot be accomplished or fulfilled prior to termination or which relate
to obligations of the parties accrued prior to termination.

Non-Competition. Bayer shall not, during the term of this Agreement,
manufacture, sell, distribute or cause to be distributed a competing point of
care coagulation product in the Territory in the Specified Markets.

Arbitration.

         Except for terminations pursuant to Section 11.3 above, all disputes,
         controversies and differences which may arise between the parties out
         of, in relation to or in connection with this Agreement, or for the
         breach thereof, or any claim based on or arising from any alleged
         wrongful conduct or omission related to this Agreement, may upon mutual
         agreement of the parties, be determined by arbitration. The arbitration
         shall be conducted in accordance with the Rules of the American
         Arbitration Association ("AAA"), Supplementary Procedures for Large
         Complex Disputes, in effect as of the commencement of the arbitration,
         as modified by the provisions of this paragraph. The arbitration shall
         be held in Raleigh, North Carolina if the arbitration is called for by
         Pharmanetics and in Boston, Massachusetts if the arbitration is called
         for by Bayer. Whenever a party desires to request arbitration
         proceedings, such party shall first cause its chief executive officer
         or other designated and authorized officer to contact the other party;
         which shall cause its chief executive officer or other designated and
         authorized officer to make good faith efforts to resolve any such
         dispute prior to arbitration or litigation.

         No provision of this section shall limit the right of either party to
         this Agreement to obtain provisional or ancillary remedies from a court
         of competent jurisdiction before, after or during the pendency of any
         arbitration if injunctive relief from the court is necessary to prevent
         serious and irreparable injury to one party or the other. The parties
         acknowledge that for purposes of this Agreement (1) preliminary
         injunctions, appointments of receivers, attachments, temporary
         protective orders and writs of possession constitute "provisional
         remedies," and (2) judicial actions to enforce a decision reached
         pursuant to this section constitute "ancillary remedies."

Severability. In the event that any provision of this Agreement shall be found
in any jurisdiction to be in violation of public policy or illegal or
unenforceable in law or equity, such finding shall in no event invalidate any
other provision of this Agreement in that jurisdiction, and this Agreement shall
be deemed amended to the minimum extent required to comply with the law of such
jurisdiction.

Entire Agreement. This Agreement states the entire agreement between the parties
hereto about the transactions contemplated hereby and may not be amended or
modified except by written instrument duly executed by the parties hereto.

No Waiver. The failure of either party hereto to enforce at any time, or for any
period of time, any provision of this Agreement shall not be construed as a
waiver of such provision or of the right of such party thereafter to enforce
each and every provision.

Assignment, Binding Effect. Neither party shall assign this Agreement nor any of
their respective rights or obligations hereunder without the prior written
consent of the other party, except that either party may assign this Agreement
to any of its Affiliates or to any person to which substantially all of the
assets comprising its hemostasis products business are transferred by operation
of law or otherwise, including, but without limitation, by merger or transfer of
stock. Any other attempted assignment without such consent shall be void. Any
assignee or transferee of this Agreement and/or the rights or obligations
hereunder shall expressly assume in writing all obligations of the
assignor/transferor pursuant to this Agreement. In performing this Agreement,
Bayer may, upon sixty (60) days advance written notice, delegate to its
Affiliates its obligations hereunder. Bayer Diagnostics shall remain primarily
liable to Pharmanetics despite such delegation.

Independent Contractor. Each party shall act as the independent contractor of
the other party. Neither party shall be the legal agent of the other for any
purpose whatsoever and therefore has no right or authority to make or underwrite
any promise, warranty or representation, to execute any contract or otherwise to
assume any obligation or responsibility in the name of or in behalf of the other
party, except to the extent specifically authorized in writing by the other
party. Neither of the parties hereto shall be bound by or liable to any third
persons for any act or for any obligation or debt incurred by the other toward
such third party, except to the extent specifically agreed to in writing by the
party so to be bound.

Headings. All section headings contained in this Agreement are for convenience
of reference only, do not form a part of this Agreement and shall not affect in
any way the meaning or interpretation of this Agreement.

Counterparts. This Agreement may be executed in any number of counterparts and
any party hereto may execute any such counterpart, each of which when executed
and delivered shall be deemed to be an original and all of which counterparts
taken together shall constitute but one and the same instrument. It shall not be
necessary in making proof of this Agreement or any counterpart hereof to account
for any of the other counterpart.

                                       27

Force Majeure. Neither party shall be deemed to be in default for failure or
delay in performance to the extent of causes which are reasonably unforeseeable
or, if foreseeable, reasonably unremediable in spite of diligent efforts to
effect a reasonable remedy, and which are caused by act or omission of any
governmental authority or of the other party, compliance with new governmental
regulations, insurrection, riot, embargo, delays or shortages in transportation
or inability to obtain necessary materials, and Acts of God or Nature.

Insurance. Pharmanetics and Bayer shall at all times maintain insurance,
including product liability insurance, in the amount of $5,000,000.00. Each
party shall, at the request of the other party, provide such evidence of such
insurance as requested, including a certificate of insurance. Such insurance
shall not be canceled without at least thirty (30) days prior written notice to
Bayer.

Books and Records. Pharmanetics and Bayer shall, during the term of this
Agreement and for three (3) years thereafter, make and keep full and accurate
books and records showing the quantities of Products sold in sufficient detail
to determine applicable pricing pursuant to Section 7.2 and applicable Card,
commission, and Instrument credits pursuant to Sections 3.6, 5.6 and 5.7. Each
party shall be permitted to designate an independent third party such as a
nationally recognized accounting firm to inspect the applicable books and
records of the other party from time to time, during regular business hours to
the extent necessary to verify applicable pricing and credits. The designated
party shall report its findings to the requesting party. Each party agrees to
treat as Proprietary Information all information learned in the course of any
such inspection hereunder, except when it is necessary for the party to reveal
such information in order to enforce its rights under this Agreement.
Notwithstanding anything to the contrary contained herein, the party to be
inspected may waive at any time the requirement contained in this section
relating to the use of an independent third party.

Press Releases; Publicity. Neither party shall publicly disclose or announce any
term of this Agreement; provided, however, that a party may issue a press
release disclosing the existence of this Agreement and other terms only upon
prior written agreement of the other party, further provided, that each party
shall at all times be entitled to make disclosures required by applicable
securities laws.
