pursuant to Section 3.1(a) and Section 3.1(b), the Company may, through its
representatives on the U.S. Commercialization Team, propose to AZ revisions to a
draft Strategic Targeting Plan that the Company reasonably believes are
appropriate, necessary or useful to permit the Company to (i) perform its
obligations hereunder or (ii) allow the Company Sales Force to have
opportunities comparable overall (in terms of quality and quantity of Calls,
Details and other factors affecting Promotion) to those provided to the AZ Sales
Force overall to Promote the Products. AZ shall consider any such proposed
revisions in good faith, and discuss them with the Company to allow the adoption
of a final Strategic Targeting Plan that considers the interests and obligations
of the Parties,

-11-

recognizing that AstraZeneca and its Affiliates controls the commercialization
of the Products.

(d) Once a Strategic Targeting Plan is finalized pursuant to Section
3.1(a) and Section 3.1(b), either Party may propose amendments thereto, and the
Parties shall, at meetings of the U.S. Commercialization Team, discuss such
proposed amendments in good faith and in a manner consistent with that described
in Section 3.1(c)

(e) If, in connection with any discussions between the Parties
concerning the finalization of, or update or amendment to, a Strategic Targeting
Plan, the Parties are unable to reach agreement concerning any matter, and if
the resolution of such matter could be reasonably expected to have a material
adverse effect on the Company's relative ability to Promote Products, as
compared to the similarly deployed AZ Sales Force, such matter may be referred
by either Party to the JMC for resolution pursuant to the terms of the
Collaboration Agreement; provided, that the appeal process set forth in this
Section 3.1(e) shall not operate to delay or otherwise impair AZ's ability to
implement any STP, including any disputed portions thereof, which has been
approved by the U.S. Commercialization Team pending any final decision by the
JMC.

3.2. Requisite Details

The Company shall, through the Company Sales Force, provide at least
the minimum number of Calls and Details set forth in Schedule 3.2 to the
applicable Target Prescribers in accordance with the Strategic Targeting Plan;
provided that the Company Sales Force may provide up to [****], or a greater or
lesser percentage if such greater or lesser percentage is provided for the AZ
Sales Force, of the required number of Calls and Details each Calendar Year to
non-Target Prescribers; provided that the Company believes in good faith that
such Calls and Details to non-Target Prescribers are likely to result in
increased sales of the Products. For each Calendar Trimester, the Company shall
achieve a Targeting Delivery Score (currently, at least [****]) that is
consistent with the Targeting Delivery Score for the AZ Sales Force assigned to
the same Product for the same Calendar Trimester. Otherwise, the Company agrees
within fifteen (15) business days of receipt of the Calendar Trimester TDS
score, to provide AZ with an explanation for the underperformance and a
corrective action plan designed to achieve a TDS score consistent with that of
such AZ Sales Force in the next Calendar Trimester. Compliance by the Company
with the foregoing sentence shall be determined by AZ's internal call reporting
system. During the Funding Term and any Detail Funding Term, the Company shall
perform its Promotion, Call and Detail obligations hereunder exclusively through
the Company Sales Force. There will be a subset of targeted physicians that are
the sole responsibility of the Company for Promotion, in order for AZ to be able
to reasonably assess the Company's performance, which subset shall constitute
cardiologists [****].

3.3. Secondary Products

-12-

The Secondary Product to be Promoted by the Company shall be
selected by AZ from the list of AZ Affiliate products set forth in Schedule 3.3
attached hereto and disclosed to the Company within thirty (30) days prior to
the Anticipated Approval Date. At any time during the Term, AZ shall have the
right to substitute the Secondary Product with any other AZ Affiliate product
appearing on Schedule 3.3; provided that AZ may not substitute any Secondary
Product more than twice in any twelve-month period; and provided, further, that
AZ may not substitute any Secondary Product unless it is also substituting such
product for all or a substantial portion of AZ's own sales Representatives who
are promoting the Primary Product.

3.4. Services Provided by the Company

The Company shall provide Promotion services pursuant to this
Agreement through a Sales Force of up to a total of one hundred twenty-five

members of the Sales Force (including other managers), as determined by the
Sales Operations Group within ninety (90) days prior to the Anticipated Approval
Date and set forth on Schedule 3.4 hereto as necessary to supervise or support
Company Representatives in order to implement the Program (it is currently
anticipated by AZ that the ratio of Representatives to District Sales Managers
would be approximately 10-to-1). A copy of the Company's recruiting and hiring
standards shall be made available to the Sales Operations Group, and the Company
shall not make changes to such standards if the proposed changes would
materially impact the Hiring Profile, unless agreed to by the Sales Operations
Group. Each member of the Company Sales Force shall be properly trained in
accordance with the terms of ARTICLE IV. The Company, where necessary, shall
make available its Project Manager and field management personnel to accompany
Company Representatives on Calls and to ensure completion of the Calls
consistent with the terms of this Agreement. It is AZ's expectation that the
Company will ensure that each of the Company's District Sales Manager's working
time spent in the field coaching the Company's Representatives shall be
consistent with such time spent by AZ's District Sales Managers. The Company
shall remove or reassign from the Program any member of the Company Sales Force
as reasonably requested by AZ. All monies paid by AZ to the Company for
incentive compensation shall be paid out in full to all field personnel. Based

to the Parties, and account knowledge, at both the regional and national levels,
relating to the Promotion of the Products by each Sales Force, intended to
assist in the market share growth of the Products within each account.

(c) During the Funding and Detail Funding Term, if any, the Company
shall permit sales management personnel of AZ to conduct annual field
observations with the Company's Representatives in order to allow AZ to evaluate
overall quality assurance of the Program. During the Funding Term and the Detail
Funding Term, if any, AZ shall permit a reasonable number of the Company's sales

Representatives in order to allow the Company to learn first hand some of AZ's
best selling and servicing practices. Each of the foregoing field observations

prepare the initial Promotion Plan for the Products. The initial Promotion Plan
shall cover the first three (3) years following the Approval Date, and will be
updated annually on a calendar year basis. The Company shall, within thirty (30)
days of receipt, determine whether the initial Promotion Plan and any subsequent
annual update thereof is sufficient to enable the

-14-

Company to perform its obligations hereunder; provided, however, that in no
event shall any Promotion Plan alter the obligations of either Party under this
Agreement. If the Company reasonably concludes that the Promotion Plan is not
sufficient, the Company shall propose to AZ amendments to such plan. AZ shall
review such proposed amendments and shall adopt any amendments to the Promotion
Plan that the U.S. Commercialization Team in its good faith judgment deems
appropriate. Subject to the foregoing requirements, the U.S. Commercialization
Team may amend and modify the Promotion Plan in any material respect with not

Center or Medical Resources Department all PIRs received by the Company or
Company Representatives. AZ shall provide to the appropriate Company

for a specific period; provided, however, that the Company shall, at AZ's
reasonable request, audit the inventory of any Company Representative whose

adjustment of Allowable Costs to reflect any additional costs reasonably

(a) AZ and the Company shall each provide a goal-based bonus or
similar incentive payment plan for members of their respective Sales Forces to

Company the amounts reflected on such invoice by check or wire transfer on or
before AZ makes payments to any AZ Representatives for a comparable time period,
and in a manner that allows for consistency of the timing for the payment of the
same award by AZ for any AZ Representatives, but in any event, within thirty
(30) days after receipt of such invoice.

6.3. Detail Funding Term

On or before ninety (90) days prior to the conclusion of the Funding
Term, AZ shall complete an assessment of the value of the Company's
participation in the Program, and shall inform the Company in writing as to
whether it wishes to continue to fund the Company's activities on the same basis
as it did so during the Funding Term, or on some other basis, including on a
per-detail basis. If AZ informs the Company that it wishes to continue such
funding, the Parties shall negotiate the terms of any such arrangement in good
faith. If AZ wishes to fund on a per Detail basis, the Parties shall negotiate a
rate consistent with the then-going arm's length commercial rate per detail used
by third parties in comparable arrangements. Notwithstanding the foregoing,
neither Party shall be obligated to agree to the terms of any such arrangement.
The period during which the Parties agree to continued funding pursuant to this
Section 6.3 shall be called the "Detail Funding Term."

entitled, at its expense, to have access to (i) the Company's internal call
reporting system, and (ii) solely through review by a third party, books and
records (including receipts, invoices and other proof of expenditures) in the
Company's possession or control as they relate to the relevant Products, in each
case for the purpose of verifying the Company's determination of Allowable
Costs, and such other matters as AZ reasonably requests relating to the
performance by the Company of its obligations under this Agreement; provided,
however, that if such audit shows charges by the Company for Allowable Costs in
excess of five percent (5%) of the total amount owed for the Calendar Year then
being audited, the Company shall pay for the reasonable fees and expenses of
such third party to perform the audit. AZ shall have the right to exercise this
audit right no more frequently than once in each twelve (12) month period,
unless AZ reasonably believes that the Company is not complying with its

defense of the Third Party Claim any legal counsel selected by the Indemnifying

-37-

Party which shall be reasonably acceptable to the Indemnified Party. In the
event the Indemnifying Party assumes the defense of a Third Party Claim, the
Indemnified Party shall immediately deliver to the Indemnifying Party all
original notices and documents (including court papers) received by any
Indemnified Party in connection with the Third Party Claim. Subject to clause
(ii) below, if the Indemnifying Party assumes the defense of a Third Party
Claim, the Indemnifying Party shall not be liable to the Indemnified Party for
any legal expenses subsequently incurred by such Indemnified Party in connection
with the analysis, defense or settlement of the Third Party Claim. In the event
that it is ultimately determined that the Indemnifying Party is not obligated to
indemnify, defend or hold harmless an Indemnified Party from and against the
Third Party Claim, the Indemnified Party shall reimburse the Indemnifying Party
for any and all costs and expenses (including attorneys' fees and costs of suit)
and any Losses incurred by the Indemnifying Party in its defense of the Third
Party Claim with respect to such Indemnified Party.

(ii) Right to Participate in Defense. Without limiting Section
14.4(b)(i), any Indemnified Party shall be entitled to participate in, but not
control, the defense of such Third Party Claim and to employ counsel of its
choice for such purpose; provided, however, that such employment shall be at the
Indemnified Party's own expense unless (A) the employment thereof has been
specifically authorized by the Indemnifying Party in writing, (B) the
Indemnifying Party has failed to assume the defense and employ counsel in
accordance with Section 14.4(b)(i) (in which case the Indemnified Party shall
control the defense).

(iii) Settlement. With respect to any Losses relating solely
to the payment of money damages in connection with a Third Party Claim and that
will not result in the Indemnified Party's becoming subject to injunctive or
other relief or otherwise adversely affect the business of the Indemnified Party
in any manner, and as to which the Indemnifying Party shall have acknowledged in
writing the obligation to indemnify the Indemnified Party hereunder, the
Indemnifying Party shall have the sole right to consent to the entry of any
judgment, enter into any settlement or otherwise dispose of such Loss, on such
terms as the Indemnifying Party, in its sole discretion, shall deem appropriate.
With respect to all other Losses in connection with Third Party Claims, where
the Indemnifying Party has assumed the defense of the Third Party Claim in
accordance with Section 14.4(b)(i), the Indemnifying Party shall have authority
to consent to the entry of any judgment, enter into any settlement or otherwise
dispose of such Loss provided that it obtains the prior written consent of the
Indemnified Party (which consent shall not be unreasonably withheld or delayed).
The Indemnifying Party shall not be liable for any settlement or other
disposition of a Loss by an Indemnified Party that is reached without the
written consent of the Indemnifying Party. Regardless of whether the
Indemnifying Party chooses to defend or prosecute any Third Party Claim, no
Indemnified Party shall admit any liability with respect to, or settle,
compromise or discharge, any Third Party Claim without the prior written consent
of the Indemnifying Party (which consent shall not be unreasonably withheld or
delayed).

-38-

(iv) Cooperation. Regardless of whether the Indemnifying Party
chooses to defend or prosecute any Third Party Claim, the Indemnified Party
shall cooperate in the defense or prosecution thereof and shall furnish such
records, information and testimony, provide such witnesses and attend such
conferences, discovery proceedings, hearings, trials and appeals as may be
reasonably requested in connection therewith. Such cooperation shall include
access during normal business hours afforded to the Indemnifying Party to, and
reasonable retention by the Indemnified Party of, records and information that
are reasonably relevant to such Third Party Claim, and making employees and
agents available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder, and the
Indemnifying Party shall reimburse the Indemnified Party for all its reasonable
out-of-pocket expenses in connection therewith.

(v) Expenses. Except as provided above, the reasonable and
verifiable costs and expenses, including fees and disbursements of counsel,
incurred by the Indemnified Party in connection with any Third Party Claim shall
be reimbursed on a calendar quarter basis in arrears by the Indemnifying Party,
without prejudice to the Indemnifying Party's right to contest the Indemnified
Party's right to indemnification and subject to refund in the event the
Indemnifying Party is ultimately held not to be obligated to indemnify the
Indemnified Party.

14.5. Workers' Compensation and Liability Insurance

(a) The Company shall, at its own expense, provide and keep in full
force and effect, during any period during the Term following the Approval Date

MISCELLANEOUS

16.1. Dispute Resolution

(a) Except as provided in Sections 3.1(e), 6.4, 7,1(c), 11.1 and
12.4, the Parties shall attempt in good faith to settle any Disputes by
negotiations between representatives who have decision-making authority
regarding such Dispute. Within ten (10) days after either Party gives written
notice of a Dispute to the other Party (the "Dispute Notice"), representatives
of each Party having decision-making authority regarding the Dispute (subject to
Board of Directors' or equivalent approval, if required), shall meet at a
mutually acceptable time and place, and thereafter as often as they

-43-

reasonably deem necessary, to exchange relevant information and to attempt to
resolve the Dispute.

(b) If, within thirty (30) days after the Dispute Notice, the
Parties have not resolved the Dispute, upon written request by either Party to
the other Party, the Parties shall promptly appoint a mutually acceptable
Neutral to act as a mediator. If the Parties are not able to agree on an
acceptable Neutral within forty-five (45) days after the Dispute Notice, the JMC
shall be responsible for selecting a qualified, disinterested, and conflict-free
Neutral within fifteen (15) days of being approached by either AZ or the
Company. The fees and costs of the Neutral shall be shared equally by the
Parties.

(c) The Neutral shall conduct the mediation pursuant to the rules
and procedures of JAMS applicable to evaluative mediations. The Parties shall
participate in the mediation to its conclusion; provided, however, that neither
Party shall be obligated to continue to participate in the mediation if the
Parties have not resolved the Dispute in writing within one-hundred and twenty
(120) days after the Dispute Notice and if either Party shall have terminated
the mediation by delivery of written notice of termination to the other Party
following expiration of the one-hundred and twenty (120) day period. The results
of the mediation shall not be binding upon the Parties; provided, however, that
the Parties shall give good faith consideration to the settlement of the Dispute
on the basis of such result. Notwithstanding any other provision hereof to the
contrary, if one Party does not accept such result (the "Disputing Party") and
either Party thereafter pursues any other judicial or nonjudicial remedy to
conclusion, the Disputing Party shall pay the reasonable attorneys' fees, costs,
and other expenses (including expert witness fees) of the other Party, if any,
if the result of such other remedy is not more favorable to the Disputing Party
than the result of the mediation.

(d) Nothing in this Section 16.1 shall preclude either Party from
seeking interim or provisional relief, including a temporary restraining order,
preliminary injunction or other interim equitable relief concerning a Dispute
either prior to or during the mediation if necessary to protect the interests of
such Party. This Section 16.1 shall be specifically enforceable.

(e) The Parties hereto agree that none of their respective conduct
during the course of the mediation nor any of their respective statements made
or information exchanged in connection with the mediation shall be deemed an
admission of any kind by any Party. No such conduct, statements or information
may be admitted as evidence by either Party in any other subsequent proceeding
initiated by either Party. Without limiting the foregoing, no offer of
settlement made in connection with the mediation shall be admitted as evidenced
by the Parties hereto in any other subsequent proceeding initiated by either
Party.

16.2. Governing Law

-44-

The interpretation and construction of this Agreement, and all
matters relating hereto, shall be governed by the laws of the State of New York
applicable to agreements executed and to be performed solely within such State
excluding any conflicts or choice of law rule or principle that might otherwise
refer construction or interpretation of this Agreement to the substantive law of
another jurisdiction

16.3. Force Majeure

Neither Party shall be liable for delay in delivery or
nonperformance in whole or in part, nor shall the other Party have the right to
terminate this Agreement except as otherwise specifically provided in this
Section 16.3, where delivery or performance has been affected by a condition
beyond a Party's reasonable control, including inability to obtain labor,
materials or manufacturing facilities, provided that the Party affected by such
a condition shall, within ten (10) days of its occurrence, give notice to the
other Party stating the nature of the condition, its anticipated duration and
any action being taken to avoid or minimize its effect. The suspension of
performance shall be of no greater scope and no longer duration than is
reasonably required and the nonperforming Party shall use its best efforts to
remedy its inability to perform; provided, however, that in the event the
suspension of performance continues for 60 days after the date of the
occurrence, and such failure to perform would constitute a material breach of
this Agreement in the absence of such force majeure, the nonaffected Party may
terminate this Agreement by written notice to the other Party.

16.4. Waiver

A Party's failure to enforce, at any time or for any period of time,
any provision of this Agreement, or to exercise any right or remedy, does not
constitute a waiver of such provision, right or remedy, or prevent such Party
thereafter from enforcing any or all provisions and exercising any or all other
rights and remedies. The exercise of any right or remedy does not constitute an
election or prevent the exercise of any or all rights or remedies, all rights
and remedies being cumulative.

in any respect, then, to the fullest extent permitted by applicable law, (a) all
