                  (iv) Meetings. Prior to U.S. NDA Approval for the First
Product, the JDC shall meet at least once a month. After U.S. NDA Approval and
unless otherwise agreed to by the Parties, the JDC shall meet at least four
times each Calendar Year. Such meetings shall be in accordance with a schedule
and at a location mutually determined by the Parties. Ad hoc meetings of the JDC
may be called by either Party upon reasonable advance notice to the other Party.
Upon mutual agreement, such ad hoc meetings may be face-to-face or by
teleconference, video or Webex.

            (c) Representatives. The Parties, through the committee structure,
may establish and later change the number of representatives on the JMC or JDC
committee as long as an equal number of representatives from each of AstraZeneca
and AGIX are maintained. Each Party may change its representatives to the JDC or
JMC at any time by written notice to the other Party.

            (d) Committee Chairs. The JMC shall be co-chaired by AstraZeneca and
AGIX. Prior to the earlier of (a) the date U.S. NDA Approval is received and (b)
the date that AstraZeneca makes an Accelerated Assumption Payment, the JDC shall
be chaired by a representative of AGIX. After such date, the JDC shall each be
chaired by a representative of AstraZeneca.

<PAGE>

                  (ii) Decision-making Authority. Notwithstanding anything to
the contrary, neither the JDC or the JMC shall have the authority to determine
any of the matters for which (i) one or more of the Parties is allocated
decision-making authority elsewhere in this Agreement or (ii) the Agreement
provides that the matter in question is explicitly a matter requiring the mutual
or joint agreement of the Parties. Each of the JDC and JMC shall be deemed to
have a quorum if they have at least two (2) designated representatives from each
Party. A quorum shall also be deemed to have been achieved if at least ten (10)
Business Days written notice of a meeting, including a proposed agenda, has been
provided for a meeting held by telephone conference or in Atlanta, Georgia or
Puerto Rico.

                  (iii) Disputes

                        (A) JDC Disputes. The JDC, or either Party, may, after
      thirty (30) days (or such other period as the Parties otherwise agree) of
      good faith efforts to reach a unanimous decision on an issue, refer any
      unresolved issue to the respective heads of the appropriate department for
      each Party. If the department heads can not resolve such issue within ten
      (10) days, then such issue shall be referred to the JMC.

                        (B) JMC Disputes. The JMC or either Party may, after
      thirty (30) days (or such other period as the Parties may otherwise agree)
      of good faith efforts to reach a unanimous decision on an issue refer such
      issue to the officers set forth in Section 14.1(b), or their designee.
      Such officers of the Parties shall meet promptly thereafter and shall
      negotiate in good faith to resolve the issues. If the issues were raised
      by the JDC and if they cannot resolve the issue within thirty (30) days of
      commencing negotiations, prior to the earlier of (i) the date U.S. NDA
      Approval is received and (ii) the date upon which AstraZeneca makes an
      Accelerated Assumption Payment, the resolution of such issue shall be
      determined by AGIX. For all other JMC issues, the resolution of any such
      issue shall be determined by AstraZeneca.

                  (iv) Decisions Affecting Development and Commercialization
Plans. Notwithstanding anything in this Section 6 to the contrary:

                        (A) no decision by the JDC or the JMC shall affect
      AstraZeneca's control of all aspects regarding the Commercialization of
      Products;

                        (B) neither Party's rights and obligations as contained
      in this Agreement can be amended without such Party's consent;

                        (C) prior to the Assumption Date, no decision by the JDC
      or the JMC shall increase AstraZeneca's development obligations as set
      forth in the Development Plan Outline or AstraZeneca's commercialization
      obligations

                                       33

<PAGE>

      as set forth in the Commercialization Plan outline included in a letter
      delivered by AGIX to AstraZeneca on the date hereof, without the consent
      of AstraZeneca; and

                        (D) after the Assumption Date, AstraZeneca shall have
      authority to determine the resolution of any disagreement in the JMC with
      respect to the approval of the Development Plan governing activities
      following U.S. NDA Approval, even if such Development Plan was approved
      prior to U.S. NDA Approval.

            (h) IPC. No later than thirty (30) days after the Effective Date,
the Parties shall establish an Intellectual Property Committee ("IPC"). The IPC

Third Party Licenses) that, if Controlled by AGIX would be Licensed Patents or
AGIX Know-How, and where AGIX is required to pay upfront payments, royalties,
milestones or other payments to such Third Party for such rights, then:

                  (i) AGIX shall send AstraZeneca a written notice within thirty
(30) days of when AGIX has licensed or otherwise acquired such rights;

                  (ii) AstraZeneca shall have the option to acquire a
Non-Exclusive Sublicense to such rights to Develop, Manufacture and
Commercialize the Compound and Products in the Field during the Term from any

regarding obtaining a Sublicense to any such rights.

      7.4 Covenants Concerning the Products, the Compound and the Field

            (a) Expansion of Field for the Compound. In the event that AGIX can
reasonably demonstrate that the exploitation of the Compound in an indication
outside of the Field (the "EXPANDED FIELD INDICATION") presents a reasonable
commercial opportunity, then AGIX may, but shall not be required to, present to
AstraZeneca all relevant information demonstrating such opportunity for the
Compound in the Expanded Field Indication (the "INDICATION INFORMATION"). Any
dispute regarding whether an Expanded Field Indication presents reasonable
commercial opportunity shall be resolved in accordance with Section 14 of this
Agreement. For the [****] Expanded Field Indications, within thirty (30)
days of receipt of the Indication Information, (i) AstraZeneca shall pay to AGIX
[****] and (ii) the Field shall automatically be expanded to include the
Expanded Field Indication. Following the [****] payments of the Indication
Fee as described in the preceding sentence, upon delivery of Indication

<PAGE>

Field shall automatically be expanded to include such Expanded Field
Indications, but no further Indication Fees shall be due to AGIX. AstraZeneca
shall be free to Develop, Commercialize and Manufacture, in its discretion, the
Compound and any Product within any Expanded Field Indication. The provisions of
Articles 2, 3, 4, 5, 6 and Sections 8.1, 8.2 shall not apply to any Development,
Manufacture or Commercialization of a Product within the Expanded Field
Indication. AGIX shall not directly or indirectly Develop, Commercialize or
Manufacture the Compound other than pursuant to this Agreement.

            (b) Expansion of Field for Probucol Analogs. In the event that AGIX
can reasonably demonstrate that the exploitation of a Probucol Analog in the
Field (the "LICENSED PROBUCOL ANALOG") presents a reasonable commercial
opportunity, then AGIX may, but shall not be required to, present to AstraZeneca
all relevant information demonstrating such opportunity for such Licensed
Probucol Analog (the "PROBUCOL ANALOG INFORMATION"). Any dispute regarding
whether an Licensed Probucol Analog presents reasonable commercial opportunity
shall be resolved in accordance with Section 14 of this Agreement. For the
[****] Licensed Probucol Analogs, within thirty (30) days of receipt of the
Indication Information, (i) AstraZeneca shall pay to AGIX [****] and (ii) the
definition of Compound under this Agreement shall automatically be expanded to
include the Licensed Probucol Analog. Following the [****] payments of the
Probucol Analog Fee as described in the preceding sentence, upon delivery of
Probucol Analog Information regarding additional Licensed Probucol Analogs, the
definition of Compound shall automatically be expanded to include such Licensed
Probucol Analogs, but no further Probucol Analog Fee shall be due to AGIX.
AstraZeneca shall be free to Develop, Manufacture and Commercialize, in its
discretion, any Licensed Probucol Analog within the Field. The provisions of
Articles 2, 3, 4, 5, 6 and Sections 8.1, 8.2 shall not apply to any Development,
Manufacture or Commercialization of a Licensed Probucol Analog within the Field.
AGIX shall not directly or indirectly Develop, Manufacture or Commercialize any
Probucol Analog in the Field other than the Development, Manufacture or
Commercialization of Products pursuant to this Agreement and otherwise pursuant
to this Section.

            (c) Cooperation

                  (i) Subject to Section 7.4(c)(iii), AGIX shall consult with
AstraZeneca prior to engaging in any activity that AGIX believes could violate
the requirements of this Section 7.4. As part of such consultation, AGIX shall
provide to AstraZeneca such information as AstraZeneca reasonably requests to
assist AstraZeneca in discussing such activities.

                  (ii) Subject to Section 7.4(c)(iii), AstraZeneca may at any
time initiate discussions with AGIX if AstraZeneca reasonably believes that AGIX
has been violating or could violate the requirements of this Section 7.4. AGIX
shall provide to AstraZeneca such information as AstraZeneca reasonably believes
is necessary to assist

AstraZeneca in considering whether such activities constituted or could
constitute such a violation.

                  (iii) AGIX may, in lieu of consulting with AstraZeneca
pursuant to Section 7.4(c)(i) or Section 7.4(c)(ii), or in lieu of providing
information pursuant to either such section, elect to seek an opinion from a
neutral outside patent counsel with appropriate legal and technical credentials
as to whether a compound to be developed, manufactured or commercialized by AGIX
is a Probucol Analog in the Field. AGIX shall inform AstraZeneca in writing
promptly upon making any such election. AGIX shall select the neutral outside
patent counsel from the list of appropriate outside patent counsel created by
the IPC pursuant to Section 9.2(c)(i). Such counsel shall not disclose to
AstraZeneca any discussions between AGIX and the counsel, or any other
information provided to such counsel by AGIX. AGIX shall provide to AstraZeneca
a copy of any such opinion, with such opinion to be redacted as AGIX reasonably
considers appropriate to protect AGIX's proprietary interests. In the event such
counsel determines that, in such counsel's opinion, the compound AGIX proposes
to develop, manufacture or commercialize is not a Probucol Analog in the Field,
AGIX shall (assuming its activities otherwise comply with Section 7.4(b)) be
permitted to continue engaging in such activities subject to AstraZeneca's
further right to initiate discussions pursuant to Section 7.4(c)(ii); provided,
however, that to the extent AstraZeneca disagrees with such determination,
AstraZeneca may refer such issue to arbitration in accordance with Section 14.
In the event such counsel determines that, in such counsel's opinion the
compound proposed to be developed, manufacture or commercialized is a Probucol
Analog in the Field, AGIX shall cease such activities promptly; provided,
however, that to the extent that AGIX disagrees with such determination, AGIX
may refer the issue to arbitration in accordance with Section 14. If such
neutral patent counsel determines that such compound is not a Probucol Analog in
the Field and AstraZeneca refers such issue to arbitration pursuant to Section
14, AGIX shall be permitted to continue such activities during the pendency of
such arbitration proceedings.

            (d) AGIX Activities Outside this Agreement. AstraZeneca shall not
take any action that would prevent appropriate cardiovascular safety studies on
Probucol Analogs being developed for therapeutic uses outside the Field,
including, but not limited to, preclinical studies and clinical studies such as
Thorough QT Studies or long-term cardiovascular safety studies required by
Regulatory Authorities for clinical development and registration of such
compounds for indications outside the Field; provided that no such study shall
result in a label for a Probucol Analog that would permit a promotable efficacy
claim in the Field.

            (e) Equitable Remedies. Each Party acknowledges that its breach of
Section 7.4 would cause the other Party irreparable injury for which it would
not have an adequate remedy at law. In the event of such a breach, the
non-breaching Party shall be entitled to obtain injunctive relief, without the
need to show damages or harm, in addition to any other remedies it may have at
law or in equity.

            (f) Certain AstraZeneca Actions Involving AGIX Patents. AstraZeneca
shall not (i) directly or indirectly oppose, or assist any Third Party to
oppose, in any patent office or court proceeding, the grant of any patent or
patent application within the Licensed Patents, and, in any patent office or
court proceeding, dispute or directly or indirectly assist any Third Party to
dispute, the validity of any patent within the Licensed Patents or any of the
claims thereof, including opposing any application for amendment thereto; or
(ii) bring any claim or proceedings of whatever nature in relation to the
Licensed Patents against AGIX and AGIX's Affiliates (and in respect of the
foregoing their directors and officers) in respect of any activities carried out
by them under any Licensed Patents which may be the subject of a Valid Patent
Claim of the Licensed Patents; provided, however, that the foregoing shall not
prohibit AstraZeneca from bringing an action against AGIX as the result of any
breach of a representation, warranty, covenant or obligation by AGIX or
Affiliates or otherwise under or arising out of this Agreement.

            (g) Non-solicitation. During the Term, neither Party, nor any of its
Affiliates, or Representatives of such Party or Affiliate, shall, in any manner,
directly or indirectly, independently, in concert with a Third Party, or on
behalf of a Third Party, solicit to employ any of the officers or management
employees of the other Party, or of any Affiliate of such other Party, as well
as any employee in such other Party's, or the other Party's Affiliate's,
research department, without in any such case obtaining the prior written
consent of such other Party; provided that nothing herein prevents a Party from
making general solicitations not directed to the other Party's or the other
Party's Affiliate's employees, such as customary advertisements or website
postings.

8. PAYMENTS AND REPORTS

      8.1 Upfront Payment. In partial consideration for the licenses and other

than forty-five (45) days following the end of each such Calendar Quarter, the
following Royalties on Net Sales for such Calendar Quarter at the applicable
royalty rates based on Annualized

Quarterly Net Sales of all Products sold in the [****], subject to
adjustment in accordance with Section 8.4:

                  (i) [****] if such Annualized Quarterly Net Sales are less
than or equal to [****];

                  (ii) [****] if such Annualized Quarterly Net Sales are greater
than [****] and less than or equal to [****];

                  (iii) [****] if such Annualized Quarterly Net Sales are
greater than [****]and less than or equal to [****];

                  (iv) [****] if such Annualized Quarterly Net Sales are greater
than [****] and less than or equal to[****];

                  (v) [****]if such Annualized Quarterly Net Sales are greater
than [****] and less than or equal to [****]; and

                  (vi) [****]if such Annualized Quarterly Net Sales are greater
than[****] and less than [****].

The percentage rate specified in Sections 8.3(a)(i) through (vi) above shall
apply to all Net Sales and not just Net Sales above the levels specified in each
subsection. For example, if Net Sales in [****] for a Calendar Quarter are
[****], the Royalty payable to AGIX for such sales would be [****].

For Annualized Quarterly Net Sales in [****] in excess of [****], a Royalty
of[****] plus an additional Royalty of [****] of the amount in excess of [****]
shall be paid. Thus, for example, if Net Sales in [****] for a Calendar Quarter
are [****], the Royalty payable to AGIX for such sales would be [****].

            (b) Royalties for Sales Outside [****] During [****]. Except as
provided in Section 8.4, for each of the first three Calendar Quarters of each
Calendar Year during the applicable Royalty Term, AstraZeneca will pay AGIX, no
later than forty-five (45) days following the end of each such Calendar Quarter,
the following Royalties on Net Sales for such Calendar Quarter at the applicable
royalty rates based on the aggregate Annualized Quarterly Net Sales of all
Products sold in all countries and jurisdictions in the Territory other than
[****], subject to adjustment in accordance with Section 8.4:

                  (i) [****] if such Annualized Quarterly Net Sales are less
than or equal to [****];

                  (ii) [****]if such Annualized Quarterly Net Sales that are
greater than [****]and less than or equal to [****];

                  (iii) [****] if such Annualized Quarterly Net Sales are
greater than [****] and less than or equal to [****]; and

                  (iv) [****] if such Annualized Quarterly Net Sales are greater
than [****]. The percentage rate specified in Sections 8.2(b)(i) through (iv)
above shall apply to all Net Sales, and not just Net Sales above the levels
specified in each subsection. Thus, for example, if Net Sales in all countries
in the Territory [****] for a Calendar Quarter are [****], the Royalty payable
to AGIX for such sales would be [****].

            (c) Royalties Payable for the Fourth Calendar Quarter of Each
Calendar Year. Except as provided in Section 8.4, although Royalties payable for
the first three Calendar Quarters of each Calendar Year are based on Annualized
Quarterly Net Sales pursuant to Section 8.3(a) and Section 8.3(b), total
Royalties for each Calendar Year shall be based on total Net Sales for such
Calendar Year. As the level of Annualized Quarterly Net Sales in each Calendar
Quarter of a given Calendar Year increases or decreases, the Royalty payable for
the fourth Calendar Quarter of such Calendar Year shall be adjusted so that the
total Royalties due for such Calendar Year are paid for total Net Sales for the
entire Calendar Year rather than Annualized Quarterly Sales. Thus,
notwithstanding anything in this Section 8.3 to the contrary, Royalties owed and
paid in respect of the fourth Calendar Quarter of each Calendar Year during the
Term (and in respect of the final Calendar Quarter of the Term if it is not a
fourth Calendar Quarter) shall be determined in accordance with this Section
8.3(c).

                  (i) First, Royalties owed for Net Sales for the entire
Calendar Year [****]shall be determined as follows, subject to adjustment in
accordance with Sections 8.4:

                        (A) [****] if such total Net Sales for such Calendar
      Year are less than or equal to [****];

                        (B) [****] if such total Net Sales for such Calendar
      Year are greater than [****] and less than or equal to [****];

                        (C) [****] if such total Net Sales for such Calendar
      Year are greater than [****] and less than or equal to [****];

                        (D) [****] if such total Net Sales for such Calendar
      Year are greater than [****]and less than or equal to [****];

                        (E) [****] if such total Net Sales for such Calendar
      Year are greater than [****] and less than or equal to [****];

                        (F) [****] if such total Net Sales for such Calendar
      Year are greater than [****] and less than [****].

For total Net Sales for such Calendar Year [****] in excess of [****], a Royalty
of [****] plus an additional Royalty of [****] of the amount in excess of [****]
shall be paid.

                  (ii) Second, Royalties owed for Net Sales for the entire
Calendar Year for [****] shall be determined as follows, subject to adjustment
in accordance with Section 8.4:

                        (A) [****] if such total Net Sales for such Calendar
      Year are less than or equal to [****];

                        (B) [****] if such total Net Sales for such Calendar
      Year are greater than [****] and less than or equal to [****];

                        (C) [****]if such total Net Sales for such Calendar Year
      are greater than [****] and less than or equal to [****]; and

                        (D) [****] if such total Net Sales for such Calendar
      Year are greater than [****].

                  (iii) Third, the sums determined pursuant to Section 8.3(c)(i)
and Section 8.3(c)(ii) shall be added together.

                  (iv) Fourth, the total Royalties paid by AstraZeneca in
respect of the first three Calendar Quarters for such Calendar Year shall be
subtracted from the amount determined pursuant to Section 8.3(c)(iii).

                  (v) Finally, the Royalty due and payable in respect of the
fourth Quarter of the Calendar Year shall equal the amount determined pursuant
to Section 8.3(c)(iv).

                  (vi) For example, if total Royalties paid in the first three
Calendar Quarters of a given Calendar Year are [****], and Net Sales for such
Calendar Year [****] are [****] and Net Sales for such Calendar Year for [****]
are [****], and there are no adjustments pursuant to Section 8.4, the Royalty
due for the fourth Calendar Quarter of such Calendar year is [****].

      8.4 Adjustments and Changes to Royalty Rates in Certain Circumstances

            (a) End of Royalty Term. Notwithstanding anything else to the
contrary in Section 8.3, if, during the applicable Royalty Term in any country
in the Territory, there ceases to be a Valid Patent Claim of a Licensed Patent,
Joint Patent or

AstraZeneca Patent that would preclude a Third Party from developing, making,
using, selling or importing such Product in such country, then during the
remainder of the applicable Royalty Term, Royalties payable pursuant to this
Section 8 shall be reduced in such country so that they would equal [****] of
the Royalties that otherwise would have applied during such period in such
country (taking into account all adjustments, including those under subsections
(b) through (f) below), but for this Section 8.4(a). For example, if Net Sales
[****] for the first Calendar Quarter of a particular Calendar Year was [****]
and further assuming that on the day immediately preceding such Calendar Quarter
there ceases to be a Valid Patent Claim of a Licensed Patent, Joint Patent or
AstraZeneca Patent that would preclude a Third Party from developing, making,
using, selling or importing such Product [****], and if the Net Sales [****] for
such first Calendar Quarter was [****] (and further assuming that there were not
other sufficient Net Sales [****] that increased the applicable royalty rate to
more than [****]), then the Royalty payable to AGIX for such sales [****] would
be [****]. Any such Royalties shall be payable at the times and under the
circumstances otherwise provided in this Section 8.

            (b) Third Party Royalties

                  (i) The Royalties required to be paid with respect to any
particular country and any particular Calendar Quarter pursuant to Section 8.3
shall be subject to a reduction by AstraZeneca in an amount equal to [****] of
the amount of Third Party Royalties (other than royalties and other payments
paid pursuant to Pre-Existing Third Party Licenses arising out of the
Development or Commercialization of Products) that were paid by AstraZeneca in
such country during such Quarter to any Third Party that is or has at any time
been an Affiliate of AGIX.

                  (ii) The Royalties required to be paid with respect to any
particular country and any particular Calendar Quarter pursuant to Section 8.3
shall be subject to a reduction by AstraZeneca in an amount equal to [****] of
the amount of Third Party Royalties (other than royalties and other payments
paid pursuant to the Pre-Existing Third Party Licenses arising out of the
Development or Commercialization of Products) that are paid by AstraZeneca in
such country during such Calendar Quarter; provided however, that:

                        (A) such reduction may be made only to the extent such
      Third Party Royalties have not previously been subject to reduction
      pursuant to this Section 8.4; and

                        (B) no reductions in royalties otherwise due to AGIX
      shall exceed an amount equal to [****]of the amount otherwise due in such
      country pursuant to Section 8.3 for such Calendar Quarter.

Any amount that has not been reduced on such date because of this Section 8.4
shall not be eligible for further reduction in any succeeding royalty payment or
payments due for

such Product. AstraZeneca shall be responsible for any financial obligations
accruing after the Effective Date under the Pre-Existing Third Party Licenses
arising out of the Development or Commercialization of Products. AGIX shall not
amend a Pre-Existing Third Party License without the prior written consent of
AstraZeneca; provided, however, that consent shall not be unreasonably withheld;
provided further that AstraZeneca shall be permitted to withhold consent for any
amendment that materially increases costs or that decreases AstraZeneca's rights
under such Pre-Existing Third Party License.

            (c) Generic Competition. Notwithstanding anything else to the
contrary in this Agreement, for any Product in any country in the Territory, if
and so long as there is Generic Competition with respect to such Product, then
AstraZeneca shall not be obligated to pay AGIX any Royalties pursuant to this
Agreement in respect of Net Sales for such Product in such country. If Generic
Competition commences and no longer exists in such country for such Product,
then the Royalty obligations for Net Sales of such Product in such country shall
be reinstated from the date of cessation of such Generic Competition until the
end of the Royalty Term, or until Generic Competition occurs again in such
country for such Product.

            (d) Sublicenses

                  (i) During the applicable Royalty Term in each country in the
Territory, for any Compulsory Sublicense, AstraZeneca will pay AGIX, no later
than forty-five (45) days following the end of the preceding Calendar Quarter, a
payment equal to [****] of all amounts received by AstraZeneca as consideration
during such Calendar Quarter for any Compulsory Sublicense (either from the
Sublicensee or any other Third Party) in the form of milestones, royalty
payments or any other form of consideration (including, if the Sublicensee
purchases Product from AstraZeneca for resale, the gross sales price paid by
such Sublicensee minus AstraZeneca's costs for Manufacture of such Product),
subject to adjustment in accordance with Section 8.4.

                  (ii) Sales of Products under or as a result of Noncompulsory
Sublicenses, for purposes of the definition of "Net Sales" and for calculating
royalties under this Section 8.4, shall be deemed to be "Net Sales" by
AstraZeneca.

            (e) Coated Stents. Notwithstanding anything else in this Section 8
to the contrary, if the JMC approves the Development and Commercialization of
Coated Stents, the Parties will, prior to Product Launch of any such Product,
negotiate in good faith the Royalties and any other payments to be paid to AGIX
in respect of sales of such Product, with such terms to be based on terms then
prevailing in comparable arrangements involving Third Parties and all other
relevant factors.

            (f) Combination Products

                  (i) For Combination Products containing one or more Exclusive
Market Product(s), in each country in which such Combination Product is sold,
Net Sales shall be adjusted as follows:

                        (A) Net Sales shall be multiplied by the Net Sales of
      the Combination Product during the applicable Calendar Quarter by the
      fraction A/(A+B), where A is the Standard Sales Price of the Product
      containing the same amount of Compound as the sole active ingredient as
      the Combination Product in question in such country and B is the Standard
      Sales Price of the ready for sale product containing the same amount of
      the other therapeutically active ingredient that is contained in the
      Combination Product in question in such country, in each case during the
      applicable Calendar Quarter. For clarity, if a Combination Product
      contains three or more active ingredients (including the Product), the
      Standard Sale Price of such additional Exclusive Market Products ,
      calculated in the same manner as described above, shall be included in the
      denominator so that such fraction shall be A/(A+B1+ B2+...).

                        (B) If sales of the Product or the Exclusive Market
      Product did not occur in such Calendar Quarter, then the most recent
      previous Standard Sales Price of the Product containing the same amount of
      Compound as the sole active ingredient as the Combination Product in
      question in the given country, shall be used. If, in a specific country,
      both a Product containing the Compound(s) and a product containing the
      other active ingredients in such Combination Product are not sold
      separately, a market price for such Product and such other active
      ingredients shall be negotiated by the Parties in good faith based upon
      the costs, overhead and profit as are then incurred for such Combination
      Product and all Products then being made and marketed by AstraZeneca and
      having an ascertainable market price that are comparable to such Product
      or such other active ingredients, as applicable; provided, however, that
      in no event shall the Royalty due to AGIX for such Combination Product be
      less than [****] of what the Royalty would have been if the Net Sales for
      such Combination Product were calculated by multiplying the number of
      units of the Combination Product sold times the selling price of such
      Product as if sold alone.

                        (C) Notwithstanding anything else in this Section
      8.4(f)(i) to the contrary, if AstraZeneca or one of its Affiliates or
      Sublicensees sells such a Combination Product in a country for less than
      [****] of the sum of the then-Standard Sales Prices of the Product and the
      Exclusive Market Product(s) that make up such Combination Product as sold
      separately in finished form in such country, then in no event shall the
      Royalty due to AGIX for such Combination Product be less than [****] of
      what the Royalty would have been if

      the Net Sales for such Combination Product were calculated by multiplying
      the number of units of the Combination Product sold times the selling
      price of the Product as if sold alone. If the Product is not then sold
      separately in such country, then the most recent previous Standard Sales
      Price in such country of such Product shall be used.

                  (ii) For Combination Products containing, as active
pharmaceutical ingredients, only Non-Exclusive Market Product(s) and a Product,
in each country in which such Combination Product is sold, the Net Sales for
such Combination Product shall be calculated by multiplying the number of units
of the Combination Product sold by the selling price of the Product as if sold
alone.

      8.5 Payment; Report

            (a) Reports. Following the First Commercial Sale of a Product,
AstraZeneca shall furnish to AGIX, within forty-five (45) days following the end
of each Calendar Quarter, a written report for such Calendar Quarter showing,
for each Product in each country in the Territory, (i) the adjustments resulting
from the deductions in the definition of "Net Sales" and from the calculation of
the amount of any applicable reductions or limitations pursuant to Section 8.4
to the extent reasonably available to AstraZeneca on a global basis; (ii) total
Net Sales; and (iii) the calculation of Royalties due.

            (b) Records and Audit. AstraZeneca shall maintain, and shall require
its Affiliates and Sublicensees to maintain, for at least [****], complete and
accurate books and records in connection with the sale of Products as necessary
to allow the accurate calculation of the Royalties.

      8.6 Exchange Rate; Manner and Place of Payment

            (a) Payments. Unless otherwise specified in writing by the receiving
Party, all payments to be made by a Party making a payment under this Agreement
shall be made in United States dollars and shall be paid by bank wire transfer
in immediately available funds selected by the paying Party to a bank account
designated in writing by the receiving Party from time to time.

            (b) Sales [****]. With respect to sales [****], Net Sales shall be
converted from the local currency to United States dollars based on applicable
currency exchange rates (as provided in Section 8.6(c)), and royalty amounts
owed shall be calculated based on such dollar amounts and paid to AGIX.

            (c) Exchange Rate. The conversion of non-U.S. dollar sales into U.S.
dollar sales shall be calculated in accordance with AstraZeneca's then current
foreign exchange conversion methodology for external financial reporting to the
Securities and Exchange Commission.

            (d) Tax Liability. In the event that, between the Effective Date and
the end of AGIX's second full tax year after Product Launch, any amount paid by
AstraZeneca to AGIX under this Section 8 suffers tax to be withheld by
AstraZeneca under applicable law or regulation ("Withholding Tax") for which
AGIX cannot obtain offset against U.S. corporate tax liability before foreign
tax credit for that year, then AstraZeneca shall, upon AGIX's claim to be
delivered in writing within four (4) months of the end of the relevant year,
advance AGIX the amount of such Withholding Tax to the extent that such offset
has not been obtained. Within thirty (30) days after the actual filing date of a
subsequent U.S. federal income tax return on which any amount of such
Withholding Tax so advanced under the preceding paragraph is offset against
AGIX's U.S. corporate tax liability as filed, AGIX shall repay to AstraZeneca
the corresponding amount previously advanced to AGIX by AstraZeneca, without
interest. In any event, all amounts advanced under this Section 8.6(d) by
AstraZeneca to AGIX shall, to the extent not previously repaid pursuant to the
immediately preceding sentence, be repaid by AGIX to AstraZeneca, without
interest, no later than the [****] of the Product Launch. For the avoidance of
doubt, [****]. AGIX will provide to AstraZeneca (or an agreed independent Third
Party accountant at AGIX's cost) upon the occasion of each advance and within
(30) days of filing of each relevant U.S. federal income tax return, supporting
documentation or a statement from their auditors or appointed tax advisers that
is sufficient to evidence the extent to which the Withholding Tax paid and
temporarily borne by AstraZeneca can or cannot be credited wholly or in part
against AGIX's U.S. tax for the relevant year when so prioritized.

            (e) Income Tax Withholding. Subject to Section 8.6(d), each Party
shall pay any and all taxes levied on account of any license fee, royalty or
milestone payments made to it under this Agreement. If any taxes are required by
applicable law or regulation to be withheld by a Party, such Party shall (i)
deduct such taxes from the payment made to the other Party, (ii) timely pay the
taxes to the proper Governmental Authority, and (iii) send proof of payment to
the other Party and certify its receipt by the Governmental Authority within
thirty (30) days following such payment. If AGIX is entitled, subject only to
any requirement to file a prescribed form or other documentation, the
preparation and filing of which would not be unduly burdensome, under any
applicable tax treaty or local law to a reduction of rate of any applicable
withholding tax, upon AstraZeneca's prompt request therefore, AGIX shall deliver
to AstraZeneca or the appropriate Governmental Authority (with the assistance of
AstraZeneca) such forms or documentation, and AstraZeneca shall apply the
reduced rate of withholding once formal confirmation of AGIX's entitlement
thereto has been received from the relevant tax authority

            (f) Indirect Taxes. Notwithstanding anything else contained in this
Section 8.6, this Section 8.6(f) shall apply with respect to Indirect Taxes. All
payments are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable
in respect of any payments, the paying Party shall pay such Indirect Taxes at
the applicable rate in respect of any such payments following the receipt, where
applicable, of an Indirect Taxes

invoice in the appropriate form issued by the receiving Party in respect of
those payments, such Indirect Taxes to be payable on the due date of the
Payments to which such Indirect Taxes relate.

            (g) Late Fee. All past due amounts owed by one Party to the other
Party under this Agreement shall bear simple interest at the U.S. Prime Rate, as
reported by the Wall Street Journal, Eastern Edition, on the due date (or the
next Business Day if the due date is not a Business Day), calculated based on
the number of days between the actual date the payment is made and the date the
payment was due; provided, however, that in no event shall such rate exceed the
maximum legal annual interest rate. The payment of such interest shall not limit
a Party from exercising any other rights it may have as a consequence of the
lateness of any payment.

            (h) Audits

                  (i) The Parties shall permit upon written notice to the other
Party, at its own expense, a certified public accountant or a person possessing
similar professional status and associated with an independent accounting firm
acceptable to the Parties to inspect, during normal business hours, and not more
than once in any Calendar Year, to audit the other Party's books and records as
may be reasonably necessary to verify the accuracy of the financial reports
furnished by the other Party pursuant to this Agreement or of any charges,
reimbursements or payments made by the other Party pursuant to this Agreement,
in respect of any Calendar Year ending not more than three (3) years prior to
the date of such notice.

                  (ii) Each Party recognizes that the Third Party performing any
audit for a Party may perform accounting services for a Party, and each Party
hereby waives any conflict of interest relating to the use of such accounting
firm.

                  (iii) Upon the expiration of the [****] following the end of
any Calendar Year (or [****] with respect to Section 8.6(d)), the calculation of
amounts payable with respect to such fiscal year shall be binding and conclusive
upon the Parties, and the Parties shall be released from any liability or
accountability with respect to payments for such year.

                  (iv) The report prepared by any Third Party, if used by a
Party, shall contain the conclusions of such Third Party regarding the audit and
shall specify that the amounts paid pursuant thereto were correct or, if
incorrect, the amount of any underpayment or overpayment.

                  (v) In the case of any payment of Royalties, if such report
shows any underpayment by AstraZeneca, AstraZeneca shall remit to AGIX within
thirty (30) days after receipt of such report, (A) the amount of such
underpayment; and (B) if such underpayment exceeds [****] of the total amount
owed for the Calendar Year then being audited, the reasonable and necessary fees
and expenses of such Third Party to

perform the audit, subject to reasonable substantiation thereof. If such report
shows any overpayment by AstraZeneca, then at AstraZeneca's option, such
overpayment shall either be refunded to AstraZeneca by AGIX within thirty (30)
days of receipt of the audit report, or be creditable against amounts payable by
AstraZeneca in subsequent payment periods.

                  (vi) The Parties agree that all information subject to review
under this Section 8.6(h) is Confidential Information and that each Party shall
retain and cause any Third Party used for any audit to retain all such
information in confidence.

      8.7 Representations and Covenants Concerning Certain Matters

            (a) Insurance. AstraZeneca is and, throughout the Term, will remain
a party to the insurance program designated internally as the AstraZeneca Group
Insurance Programme on the same basis as any other Affiliate in the internally
designated AstraZeneca Group. The AstraZeneca Group Insurance Programme policy
indemnifies each Affiliate of AstraZeneca Group, including AstraZeneca, for any
legal or contractual liability to compensate third parties for, inter alia,
product liability subject to the policy's terms, conditions and limitations.

            (b) Balance Sheet. The unaudited balance sheet for AstraZeneca dated
December 15, 2005 that has been delivered to AGIX is true and correct in all
material respects and presents fairly the financial position of AstraZeneca as
of the date thereof.

            (c) Material Restructuring. Each Party agrees that, in the event
that a Material Restructuring of such Party is contemplated, no later than
thirty (30) days prior to the consummation of such Material Restructuring, such
Party will advise the other Party of such contemplated Material Restructuring
and the Parties will discuss in good faith whether any amendments are required
to this Agreement to ensure continued performance under the agreement by both
Parties following any such Material Restructuring.

9. INTELLECTUAL PROPERTY

      9.1 Ownership of Inventions; Obligation to Update

            (a) Ownership of Inventions. Each Party shall own any inventions
that are first identified, discovered, developed, conceived or made solely by
its employees, agents or independent contractors in conducting their activities
hereunder.

            (b) Assignment. Each Party shall promptly execute all papers and
instruments, and/or require, to the extent possible, its employees, agents,
consultants or

                                       51

<PAGE>

independent contractors to execute such papers and instruments, as applicable,
so as to effectuate the ownership of AGIX IP, AstraZeneca IP and Joint IP.

            (c) Obligation to Supplement AGIX Compound Patents. AGIX shall amend
or supplement Exhibit 1A from time to time to include any Patent Controlled by
AGIX or its Affiliates after the Effective Date that claims or is directed
solely to the Compound or the Product or solely to the Development, Manufacture,
formulation or use of the Compound or the Product in the Field. Upon such
inclusion, any such Patent shall be deemed an "AGIX Compound Patent."

            (d) Obligation to Supplement Other AGIX Patents. AGIX shall amend or
supplement Exhibit 1C from time to time to include any Patent Controlled by AGIX
or its Affiliates after the Effective Date that is necessary or useful for the
Development, Manufacture, Commercialization, use, sale, offer for sale or
importation of the Compound or any Products in the Field. Upon such inclusion,
any such Patent shall be deemed an "Other AGIX Patent."

            (e) Joint Inventions; Joint Patents. Inventions that are identified,
discovered, developed, conceived or made jointly by employees, agents,
consultants or independent contractors of each Party shall be deemed "JOINT
INVENTIONS". To the extent that the Parties file Patents directed to Joint
Inventions, such Patents shall be deemed "JOINT PATENTS," and ownership thereof
shall be determined in accordance with United States patent laws. For purposes
of this Section 9, any Joint Patents filed by the Parties shall be treated as
AGIX IP.

      9.2 IPC

            (a) IPC. The Parties shall form the IPC, pursuant to Section 6.3(h),
which shall function under the procedures established in this Section 9.2, until
the Parties agree to disband such committee, to oversee, facilitate, discuss,
manage and implement the filing, procurement, enforcement, and defense of
intellectual property matters relating to this Agreement in accordance with the
terms hereof.

            (b) Composition

                  (i) The IPC shall have two (2) named representatives of AGIX
and two (2) named representatives of AstraZeneca, who may or may not be members
of the JMC or the JDC. Each Party shall appoint its respective representatives
to the IPC and may, from time to time, substitute one or more of its
representatives, in its sole discretion, effective upon notice to the other
Party of such change.

                  (ii) The IPC shall be co-chaired by one (1) representative of
AGIX and one (1) representative of AstraZeneca.

                                       52

<PAGE>

                  (iii) The IPC representatives shall have appropriate technical
or legal credentials, experience and knowledge, and ongoing familiarity with
Compounds, Products and related Patents and other intellectual property issues
arising under this Agreement. Members of the IPC may delegate from time to time
certain matters arising within the IPC as they from time to time deem
appropriate.

                  (iv) Each Party may designate its own internal or external
patent counsel (who may or may not be a member of the IPC) who may attend IPC
meetings ("IPC PATENT COUNSEL"). The Parties shall take reasonable efforts to
preserve the lawyer-client privilege and work product privilege applicable to
the communications and work of IPC Patent Counsel and other legal counsel, and
shall enter into a shared-interest agreement.

                  (v) Additional representatives or consultants may from time to
time, by mutual consent of the Parties, be invited to attend IPC meetings,
subject to such representative's or consultant's written agreement to comply
with the confidentiality and non-use obligations equivalent to those set forth
in Section 10, and provided that such additional representatives shall have no
vote.

                  (vi) Alliance Managers may attend any IPC meeting without
notice or consent.

            (c) Governance. In matters where the IPC has jurisdiction to make
decisions, such decisions shall be made by unanimous vote, with each Party's
representatives on the IPC collectively having one (1) vote.

                  (i) In the event that the IPC cannot or does not, after good
faith efforts, reach agreement on an issue (including, but not limited to, the
inventorship and ownership of Patents and Joint Patents under Section 9.1(e))
within thirty (30) days (or such shorter period as may be appropriate if prompt
action is required), then such issue shall be referred to the officer employed
by each Party who is in charge of intellectual property matters. If such
officers cannot resolve such issue, such issue shall then be referred to a
mutually agreed upon neutral outside patent counsel that has appropriate legal
and technical credentials; provided, however, that a Party may object to the
retention or continued retention of such counsel if such Party reasonably
believes such retention would be prejudicial to its intellectual property
interests (including, without limitation, conflicts of interest, such as if
outside counsel prosecutes patents for compounds similar to the Compound on
behalf of Third Parties, but excluding any perceived conflict of interest as a
result of the application of the standards described in Section 9.2(c)(ii)). A
list of appropriate counsel from which such neutral outside patent counsel may
be selected shall be created by the IPC promptly after the Effective Date and
approved by each Party. Such list may be updated from time to time as the IPC
deems appropriate. Such neutral outside counsel shall consider the interests of
both Parties when recommending a course of action. The IPC shall resolve issues
in a manner consistent with the recommendation of the neutral outside patent
counsel.

                                       53

<PAGE>

                  (ii) For any decisions concerning a Patent made by the IPC, or
by the neutral counsel, described in Section 9.2.(c)(i),

                        (A) that involves a Compound-Only Issue, such decision
      shall favor an outcome that allows for the strongest patentable scope of
      patent rights afforded for the Compound, taking into account the invention
      disclosed in light of any relevant prior art, and the longest possible
      term for such Patent.

                        (B) that involves a Mixed Issue, such decision shall
      favor an outcome that allows for the strongest patentable scope of patent
      rights afforded for the Compound, taking into account the invention
      disclosed in light of any relevant prior art, and the longest possible
      term for such Patent; provided, however that such decision may not
      reasonably, materially jeopardize the validity, enforceability or scope of
      any claim of any Licensed Patent.

                  (iii) The IPC may establish and revise from time to time rules
for operation, in such form and detail as the IPC considers appropriate.

            (d) Authority and Jurisdiction

                  (i) The IPC's decision-making authority shall be limited to
matters related to Licensed Patents, Blocking Patents, Orange Book listings and
patent term extensions. The IPC will discuss (but not decide) the status of
AstraZeneca Patents, AGIX Know-How and AstraZeneca Know-How, and will discuss
and review data and information, consider and advise on any technical issues
that arise, and discuss patent application filing priorities.

                  (ii) In no event shall the IPC have the right:

                        (A) to modify or amend the terms and conditions of this
      Agreement;

                        (B) to review, direct or control, or make any decisions
      or determinations with respect to, the Development or Commercialization or
      Manufacturing of the Compound or Product (except with respect to Patent or
      other intellectual property issues relating thereto);

                        (C) to determine which personnel of a Party perform
      activities relating to matters affecting AGIX IP, or act as such Party's
      representatives on the IPC;

                        (D) to make any decision with respect to a Party's
      Prosecution activities, except as provided for in Section 9.3; and

                                       54

<PAGE>

                        (E) to determine any such issue in a manner that would
      conflict with the express terms and conditions of this Agreement.

            (e) Meetings

                  (i) The IPC shall meet in accordance with a schedule
established by mutual written agreement of the Parties, but no less frequently
than twice per year, with the location for such meetings to be mutually agreed
by the Parties, with the first meeting of the IPC to occur no later than fifteen
(15) days after the Effective Date.

                  (ii) Either Party may call for non-scheduled meetings of the
IPC upon reasonable notice, which shall occur at mutually agreeable times. The
IPC, upon mutual agreement, may meet in person or by means of teleconference,
videoconference, Webex or other similar communications equipment.

                  (iii) No IPC meeting may be conducted unless at least one (1)
representative of each Party is participating.

                  (iv) Each Party shall bear its own expenses related to the
attendance of such meetings by its representatives.

      9.3 Patent Prosecution

            (a) Prosecution. As used herein, "PROSECUTION" shall mean the
preparation, filing, prosecution and maintenance of patents or patent
applications and includes any procedure or practice before an administrative
agency such as the United States Patent and Trademark Office, or an equivalent
agency, including but not limited to interferences, reexaminations,
examinations, protests, reissues, oppositions, and the like.

            (b) Prosecution Activities

                  (i) Subject to Section 9.3(b)(ii), AGIX shall control
Prosecution of all Licensed Patents and Joint Patents, under the direction of
the IPC. AstraZeneca shall have the right to comment on Prosecution activities
by AGIX to the extent that such activities involve a Licensed Patent or Joint
Patent. AGIX shall identify any such Prosecution activity to the IPC and provide
the IPC copies of any official action, filing (including a draft patent
application), communication, proposed submission in response to, and associated
data or information, in a timely manner but in no case less than fourteen (14)
days prior to the date any response to such official action or said application
is proposed to be filed. AGIX and its patent counsel will reasonably consider
AstraZeneca's comments thereon. If AstraZeneca does not provide AGIX with timely
comments, AGIX shall be free to proceed with its submission or other
contemplated action consistent with the direction of the IPC.

                                       55

<PAGE>

                  (ii) For any pending patent applications within the Licensed
Patents or any new patent applications that would otherwise be included in the
Licensed Patents that the IPC believes should be filed, AGIX shall file and
Prosecute patent applications or, if in the IPC's judgment the filing or
prosecution of such applications would materially adversely affect any Licensed
Patents, claims within patent applications, that in either case claim or are
directed solely to the Compound or Product, or the Development, Manufacturing,
formulation or use thereof. Any Prosecution activity in such patent application
shall be directed by the IPC, in accordance with Section 9.3(b)(i), and
implemented by AGIX in a manner consistent with Section 9.2(c)(ii).

            (c) AstraZeneca Prosecution Activities. AstraZeneca shall control
Prosecution of all AstraZeneca Patents, at its sole expense; provided, however,
that AstraZeneca shall reasonably consider AGIX's comments thereon. AstraZeneca
shall identify any such Prosecution activity to the IPC and provide the IPC
copies of any official action, filing (including a draft patent application),
communication, proposed submission in response to, and associated data or
information, in a timely manner but in no case less than fourteen (14) days
prior to the date any response to such official action or said application is
proposed to be filed. AstraZeneca and its patent counsel will reasonably
consider AGIX's comments thereon; provided, however, that resolution of any
issue under this Section 9.3(c) shall be decided by AstraZeneca in its
discretion.

            (d) Cooperation. In connection with any Prosecution activity, AGIX
and AstraZeneca shall cooperate fully and will provide each other with any
information or assistance that either Party reasonably requests, including
executing all documents necessary with respect to any such Prosecution activity.
If either Party becomes aware of any patents, information or proceeding that
relate to a Licensed Patent or Joint Patent and that may adversely impact the
validity, title or enforceability of such Licensed Patent or Joint Patent in the
Territory, such Party shall promptly notify the other Party of such patent,
information or proceeding; provided however that neither Party shall be
obligated to disclose any information that would cause such Party to violate any
confidentiality or nondisclosure obligation to a Third Party.

            (e) Abandonment. If AGIX elects to abandon or discontinue
prosecution of or not maintain any claim in a Licensed Patent or Joint Patent
anywhere in the Territory, then AGIX shall provide AstraZeneca with thirty (30)
days' prior written notice of such determination, and shall provide AstraZeneca
with the right, but not the obligation, to prosecute and maintain such claim at
AstraZeneca's sole expense and, if requested by AstraZeneca, AGIX will
reasonably assist AstraZeneca with the prosecution and maintenance of the
Licensed Patent or Joint Patent. If AGIX elects to abandon or discontinue
prosecution of a Joint Patent and AstraZeneca elects to prosecute such Joint
Patent, AGIX will assign its interests in such Joint Patent to AstraZeneca. If
AstraZeneca elects to abandon or discontinue prosecution of or not maintain any
claim in an AstraZeneca Patent or Joint Patent anywhere in the Territory, where
such claim is

                                       56

<PAGE>

necessary or useful for the Development, Manufacture, Commercialization, use,
sale, offer for sale or importation of the Compound or any Product in the Field,
then AstraZeneca shall provide AGIX with thirty (30) days' prior written notice
of such determination, and shall provide AGIX with the right, but not the
obligation to prosecute and maintain such claim at AGIX's sole expense and, if
requested by AGIX, AstraZeneca will reasonably assist AGIX with the prosecution
and maintenance of the AstraZeneca Patent.

            (f) Interference, Opposition, Protest, Reexamination and Reissue

                  (i) AGIX shall inform the IPC of any request for, or filing or
declaration of, any interference, opposition, protest, reexamination or reissue
relating to any claim in a Licensed Patent or Joint Patent within thirty (30)
days of learning of such event. The IPC shall review and consult with AGIX
regarding any submission to be made in connection with such proceeding. AGIX
shall give the IPC timely notice of any proposed settlement of an interference
relating to any Licensed Patents or Joint Patents.

                  (ii) AGIX shall conduct all activities in respect of any such
proceedings in accordance with the direction of the IPC. Any decisions made by
the IPC shall be made in accordance with Section 9.2(c)(ii).

            (g) Patent Term Extension. Where directed by the IPC, AGIX shall use
reasonable efforts to obtain patent term extension or supplemental protection
certificates or their equivalents in any country in the Territory where
applicable to any Licensed Patent or Joint Patent that claims or is directed to
a Compound or Product, and AstraZeneca shall provide reasonable assistance to
AGIX (including the provision of copies of any necessary documents) to apply for
such extension.

            (h) Expenses. Reasonable costs incurred by AGIX for any Prosecution
activities described in this Section 9.3 shall be reimbursed in accordance with
the procedures described in Section 9.9.

      9.4 Patent Marking. Each Party shall mark all Products made, used or sold
under the terms of this Agreement, or their containers, in accordance with all
applicable patent-marking laws.

      9.5 Infringement by Third Parties

            (a) Notice. If either Party learns of any infringement of any
Licensed Patent or Joint Patent, or any misappropriation or misuse of AGIX
Know-How, such Party shall promptly notify the IPC in writing of such
infringement, misappropriation or misuse; provided, however that neither Party
shall be obligated to disclose any information that would cause such Party to
violate any confidentiality or nondisclosure obligation to a Third Party.

                                       57

<PAGE>

            (b) Right to Bring and Prosecute Suit

                  (i) AGIX shall have the first right, but not the obligation,
to initiate and prosecute any legal action or other action or defense with
respect to any infringement of the Licensed Patents or Joint Patents or
misappropriation or misuse of AGIX Know-How by Third Parties, or to assume the
defense in any declaratory judgment action relating thereto, and if necessary,
to name AstraZeneca as a co-party. AstraZeneca shall cooperate fully with AGIX
in any such action. AstraZeneca shall have the right in any action or defense
brought under this Section 9.5(b)(i) to join such action voluntarily, at its own
expense, in which case the Parties shall cooperate fully in all reasonable
respects and will provide each other with any information or assistance that
either Party reasonably requests in connection with any such action.

                  (ii) If such action involves an AGIX Compound Patent and if,
within ninety (90) days of receiving the notice provided for in Section 9.5(a)
or thirty (30) days before the time limit, if any, set forth in the appropriate
laws and regulations for the filing of such actions, whichever comes first, AGIX
fails to institute or prosecute such action, or if AGIX informs AstraZeneca that
it elects not to exercise such first right, AstraZeneca thereafter shall have
the right to initiate and prosecute such action, or to assume the defense of
such declaratory judgment action, and if necessary, to name or retain AGIX as a
co-party. AGIX shall cooperate fully with AstraZeneca in any such action.

                  (iii) Except as provided in Section 9.5(b), any legal action,
other action or defense prosecuted or assumed by either AGIX or AstraZeneca
under this Section 9.5(b), including the decision to initiate any such action,
shall be subject to the direction and control of the IPC.

                  (iv) Any decision by AGIX not to initiate any action under
Section 9.5 that involves an Other AGIX Patent but that does not involve any
claims in the Field shall be made by AGIX in its sole discretion and shall not
be subject to the direction or control of the IPC.

            (c) Certifications. Each Party shall inform the other Party of any
certification regarding any Licensed Patent that it has received pursuant to
either 21 U.S.C. Sections 355(b)(2)(A)(iv) or (j)(2)(A)(vii)(IV) or its
successor provisions, or Canada's Patented Medicines (Notice of Compliance)
Regulations Article 5, or any similar provisions in a country other than the
United States and Canada, and shall provide the other Party with a copy of such
certification within five (5) days of receipt by such Party. AGIX's and
AstraZeneca's rights with respect to the initiation and prosecution of any legal
action as a result of such certification or any recovery obtained as a result of
such legal action shall be as defined in this Section 9.5.

                                       58

<PAGE>

      9.6 Infringement of Third Party Rights

            (a) Notice. If any Product Manufactured, used or sold by either
Party, its Affiliates, licensees or Sublicensees under this Agreement becomes
the subject of a Third Party claim, or there is a reasonable and credible basis
for a potential claim, of patent infringement relating to the Manufacture, use,
sale, offer for sale or importation of a Compound or Product, the Party first
having notice of the claim shall promptly notify the other Party, and the
Parties shall promptly thereafter meet to consider the claim and the appropriate
course of action.

            (b) Defense

                  (i) The Party against which the action is brought shall have
the right, but not the obligation, to defend itself against such claim or
initiate any declaratory judgment action relating to a Compound or Product, or
bring any such action necessary to protect its interest in such Compound or
Product.

                  (ii) The Party not defending against such claim or initiating
a declaratory judgment action shall have a full right to participate in any such
action at its own expense.

                  (iii) The Party that defends any claim, or that brings any
declaratory action, under this Section 9.6(b), shall keep the IPC informed of
all material developments in any proceeding involving such defense or action.
The IPC may discuss any matters affecting such defense or action, but shall not
have the authority to direct any matter in such defense or action.

      9.7 Cooperation

            (a) Joining Action and Documentation. Notwithstanding anything to
the contrary in Section 9.5 or 9.6, for any action to terminate or defend
against claims of any infringement described in Section 9.5 or 9.6, if either
Party is unable to initiate or prosecute such action or defense solely in its
own name, the other Party shall join such action voluntarily and shall execute
all documents necessary to initiate litigation to prosecute and maintain such
action or defense. In connection with any such action, AGIX and AstraZeneca
shall cooperate fully in all reasonable respects and will provide each other
with any information or assistance that either reasonably requests, including if
required, furnishing a power of attorney, giving testimony, producing documents
lawfully requested and using reasonable and diligent efforts to make available
such employees who may be helpful with respect to such litigation action or
defense. Any costs incurred as the result of such cooperation shall be borne
equally by the Parties and subject to reimbursement in accordance with the
procedures described in Section 9.9.

                                       59

<PAGE>

            (b) Information and Decision-making by IPC. Each Party shall keep
the other Party informed of developments in any action or proceeding described
in Sections 9.5 and 9.6, including, to the extent permissible by law, the
consultation and approval of any offer related thereto. All information and
developments in any such action or proceeding shall be reported to the IPC and
each Party shall reasonably consider or follow the direction and advice and
consultation of the IPC with respect to any such action as provided in this
Section 9.

      9.8 Awards and Recovery

            (a) Reasonable out-of-pocket costs and expenses incurred by a Party
in respect of any action described in Section 9.5 or 9.6, including without
limitation attorney's fees, filing and court fees, and travel expenses, shall be
borne equally by the Parties. Reimbursement for any such costs shall be in
accordance with the procedures described in Section 9.9.

            (b) Any recovery obtained by either Party in connection with or as a
result of any action contemplated by Section 9.5 or 9.6, whether by settlement
or otherwise, shall be shared in order as follows:

                  (i) Such recovery shall first be allocated to the Parties for
reimbursement in respect of their proportional costs and expenses incurred in
connection with the action after giving effect to the reimbursement provided for
in Section 9.9; and

                  (ii) Any remaining amounts after such reimbursement of the
Parties' costs and expenses shall be [****]to AGIX and [****] to AstraZeneca,
unless AGIX and AstraZeneca otherwise agree in writing.

      9.9 Costs

            (a) Within thirty (30) days following the end of each Calendar
Quarter, each Party will send a statement of reasonable out-of-pocket costs
incurred under Section 9.3, or by either Party under Section 9.2, 9.5 or 9.6 (in
such form and manner as the Parties shall agree from time to time) to the IPC
for consideration and review; provided, however, that any costs incurred related
to Pre-Existing Third Party Licenses arising out of the Development or
Commercialization of Products shall be borne by AstraZeneca.

            (b) The IPC shall, within fifteen (15) days after receipt of the
statements described in Section 9.9(a), determine whether the amounts reflected
therein are reasonable and, to the extent such amounts are so determined to be
reasonable, determine the net difference ("NET DIFFERENCE") between such
reasonable amounts reflected in such two statements.

            (c) Following the determination pursuant to Section 9.9(b), the
Party that incurred the lower costs in such Calendar Quarter shall pay to the
other Party, within sixty (60) days of the end of such Calendar Quarter, an
amount equal to [****] of the Net Difference for such Calendar Quarter.

            (d) Any issues discussed by the IPC pursuant to this Section 9.9,
which cannot be resolved by unanimous vote pursuant to Section 9.2(c) shall be
determined pursuant to Section 14.

      9.10 Trademarks

            (a) The Global Commercialization Team shall in good faith select
Product Trademarks. The Global Commercialization Team may change the Product
Trademarks at any time in its sole discretion upon the exercise of its good
faith judgment. AstraZeneca shall own all Product Trademarks and be responsible
for registering, maintaining and enforcing such Trademarks throughout the
Territory. AstraZeneca shall also own any domain names directly associated with
the Product in the Territory.

            (b) In the Territory, the Parties agree to work together in a
cooperative fashion to cause, to the extent permitted by the FDA, the corporate
Trademarks of both Parties to (i) appear in equal prominence on any Product
package inserts, main promotional pieces for professionals (e.g., detail aids
and printed advertisements), smaller promotional pieces where practical,
exhibition stand panels and monographs; and (ii) be referenced at all
investigator meetings and symposia, all Product specific press releases, and any
direct to consumer advertising.

            (c) AGIX hereby grants AstraZeneca a non-exclusive, royalty free
license to use AGIX's corporate Trademarks solely for purposes of
Commercializing Products, which license shall terminate upon the expiration or
earlier termination of this Agreement for any reason.

            (d) No Ownership or Rights in the Product Trademarks

                  (i) Except as otherwise expressly set forth in this Section
9.10, nothing in this Agreement shall give either Party any rights, title or
interest in and to any other Trademarks that are owned, licensed or maintained,
as the case may be, by the other Party. AGIX acknowledges and agrees that
AstraZeneca or its Affiliates, as the case may be, are the owners of all rights,
title and interest in and to the Product Trademarks, including any form or
embodiment thereof, and the goodwill now and hereafter associated with the
Product Trademarks. AstraZeneca and its Affiliates acknowledge and agree that
AGIX is the owner of all rights, title and interest in and to AGIX's corporate
Trademarks, including any form or embodiment thereof, and the goodwill now and
hereafter associated with the AGIX corporate Trademarks.

            (a) Confidential Information. All information disclosed by one Party
to the other Party hereunder, including the terms of this Agreement
("CONFIDENTIAL INFORMATION"), shall be maintained in confidence by the receiving
Party and shall not be disclosed to any non-Party or used for any purpose except
to exercise its rights and perform its obligations under this Agreement without
the prior written consent of the disclosing Party, except to the extent that the
receiving Party can demonstrate by competent written evidence that such
Confidential Information:

                  (i) is known by the receiving Party at the time of its receipt
and, not through a prior disclosure by the disclosing Party, as documented by
the receiving Party's business records;

                  (ii) is in the public domain other than as a result of any
breach of this Agreement by the receiving Party;

                  (iii) is subsequently disclosed to the receiving Party on a
non-confidential basis by a Third Party who may lawfully do so; or

                  (iv) is independently discovered or developed by the receiving
Party without the use of Confidential Information provided by the disclosing
Party, as documented by the receiving Party's business records.

            (b) Return of Confidential Information Upon Expiration or
Termination of Agreement. Within thirty (30) days after any expiration or
termination of this Agreement, each Party shall destroy (and certify to the
other Party such destruction) or return such Confidential Information provided
by the other Party as the other Party reasonably requests be destroyed or
returned; provided, however, that (i) the foregoing

                                       62

<PAGE>

obligation shall not apply to any matter of Confidential Information otherwise
provided for in this Agreement; and (ii) each Party may retain a single copy of

            (a) Permitted Disclosure. Each Party may disclose Confidential
Information provided by the other Party without such other Party's written
consent to the extent such disclosure is reasonably necessary in the following
instances:

                  (i) disclosure to governmental or other regulatory agencies in
order to obtain or maintain Patents on Licensed Patents and Joint Patents and to
obtain, maintain or amend any Regulatory Materials regarding a Product or
satisfy any other regulatory obligation regarding a Product, but such disclosure
may be only to the extent reasonably necessary to obtain Patents or obtain,
maintain or amend such Regulatory Materials;

                  (ii) complying with applicable court orders or governmental
regulations, including without limitation rules or regulations of the Securities
and Exchange Commission, or by rules of the National Association of Securities
Dealers, any securities exchange or NASDAQ; provided, however, that the
receiving Party shall first have given notice to the other Party hereto in order
to allow such Party the opportunity to seek confidential treatment of the
Confidential Information;

                  (iii) disclosure to consultants, agents or other Third Parties
solely to the extent required to accomplish the purposes of this Agreement or in
connection with due diligence or similar investigations by such Third Parties;

Agreement.

            (b) Written Agreements. Each Party shall obtain written agreements
from each of its employees and consultants who perform work pursuant to this

of confidentiality and to assign to such Party all inventions made by such
persons during the course of performing such work. Each Party will notify the
other Party promptly upon discovery of any unauthorized use or disclosure of the
Confidential Information of the other Party.

            (c) Required Disclosure. If a Party is required by judicial or
administrative process to disclose Confidential Information that is subject to
the non-disclosure provisions of Section 10.1, such Party shall promptly inform
the other Party of the disclosure that is being sought in order to provide the
other Party an opportunity to challenge or limit the disclosure obligations,
provided that such Party's obligations to

                                       63

<PAGE>

comply with Applicable Laws shall not be affected by such obligations.
Confidential Information that is disclosed by judicial or administrative process
shall remain otherwise subject to the confidentiality and non-use provisions of
this Section 10.2(c), and the Party disclosing Confidential Information pursuant
to law or court order shall take all reasonable steps necessary, including
without limitation obtaining an order of confidentiality, to ensure the
continued confidential treatment of such Confidential Information.

      10.3 Use of Name. Neither Party shall use the name of the other Party,
without the prior written approval of the other Party, for any purpose other
than informing employees who need to know about this Agreement; provided,
however, that AstraZeneca may, without AGIX's prior written approval, use AGIX's

US Commercialization Team or Global Commercialization Team. Without limitation,
these prohibitions apply to press releases, annual reports, prospectuses, public

that each Party may desire or be required to issue subsequent press releases
relating to the Agreement or activities hereunder. The Parties agree to consult
with each other reasonably and in good faith with respect to the text and timing
of such press releases prior to the issuance thereof, provided that a Party may
not unreasonably withhold consent to such releases, and that either Party may
issue such press releases as it determines, based on advice of counsel, are
reasonably necessary to comply with laws or regulations or for appropriate
market disclosure. In addition, following the initial press releases announcing

"AGIX INDEMNITEES"), at AstraZeneca's cost and expense, and will indemnify and
hold harmless the AGIX Indemnitees from and against any and all losses, costs,
damages, fees or expenses (including reasonable attorneys' fees and other
litigation expenses) ("AGIX LOSSES") incurred by or awarded against an AGIX
Indemnitee relating to or in connection with any claim or action, regulatory
investigation, or any other cause, brought against any AGIX Indemnitee by a
Third Party arising out of:

            (a) the labeling, packaging, marketing, use and sale of the
Products;

            (b) to the extent not controlled by AGIX, the Development,
Manufacture and Promotion of the Products;

            (c) any breach by AstraZeneca of its representations, warranties,
covenants or obligations made under this Agreement; or

            (d) any negligent act or omission or willful misconduct of
AstraZeneca or its Affiliates or any of their employees, Sublicensees,
contractors or agents, in performing its obligations under this Agreement;

provided, however, that, the foregoing indemnity shall not apply to the extent
that any such AGIX Losses are (i) attributable to the gross negligence or
willful misconduct of the AGIX Indemnitees or (ii) otherwise subject to an
obligation by AGIX to indemnify AstraZeneca Indemnitees under Section 12.2 or
any Related Agreement.

      12.2 AGIX Indemnification. AGIX agrees to defend AstraZeneca and its
Affiliates, and their respective agents, directors, officers and employees (the
"ASTRAZENECA INDEMNITEES"), at AGIX's cost and expense, and will indemnify and
hold harmless the AstraZeneca Indemnitees from and against any and all losses,
costs, damages, fees or expenses (including reasonable attorneys' fees and other
litigation expenses) ("ASTRAZENECA LOSSES") incurred by or awarded against an
AstraZeneca Indemnitee relating to or in connection with any claim or action,
regulatory investigation, or any other cause, brought against any AstraZeneca
Indemnitee by a Third Party arising out of:

            (a) to the extent controlled by AGIX, the Development of the
Products;

            (b) to the extent controlled by AGIX, the Promotion of the Products;

                                       71

<PAGE>

            (c) any breach by AGIX of its representations, warranties, covenants
or obligations made under this Agreement; or

            (d) any negligent act or omission or willful misconduct of AGIX or
its Affiliates or any of their employees, Sublicensees, contractors or agents,
in performing its obligations under this Agreement; provided, however, that, the
foregoing indemnity shall not apply to the extent that any such AstraZeneca
Losses are (i) attributable to the gross negligence or willful misconduct of the
AstraZeneca Indemnitees, or (ii) otherwise subject to an obligation by
AstraZeneca to indemnify AGIX Indemnitees under Section 12.1 or any Related
Agreements.

      12.3 Indemnification Procedures

            (a) Notice. Promptly after an Indemnitee receives notice of a
pending or threatened claim, demand, suit, action or proceeding brought or
initiated by a Third Party (an "ACTION"), such Indemnitee shall give written
notice of the Action to the Indemnifying Party to whom the Indemnitee is
entitled to look for indemnification pursuant to this Section 12 (which notice
shall describe, among other things, the nature and amount being claimed in such
Action). However, an Indemnitee's delay in providing or failure to provide such
notice shall not relieve the Indemnifying Party of its indemnification
obligations, except to the extent it can demonstrate prejudice due to the delay
or lack of notice.

            (b) Defense. Upon receipt of notice under Subsection (a) from the
Indemnitee, the Indemnifying Party shall have the duty to either compromise or
defend, at its own expense and by counsel (reasonably satisfactory to
Indemnitee) such Action. The Indemnifying Party shall promptly (and in any event
not more than twenty (20) days after receipt of the Indemnitee's original
notice) notify the Indemnitee in writing that it wishes to assume control of the
Action pursuant to this Section 12 and of its intention to either compromise or
defend such Action. The assumption of the defense of an Action by the
Indemnifying Party shall not be construed as an acknowledgement that the
Indemnifying Party is liable to indemnify the Indemnitee in respect of the
Action, nor shall it constitute a waiver by the Indemnifying Party of any
defenses it may assert against any Indemnified Party's claim for
indemnification. Once the Indemnifying Party gives such notice to the
Indemnitee, the Indemnifying Party is not liable to the Indemnitee for the fees
of other counsel or any other expenses subsequently incurred by the Indemnitee
in connection with such defense, other than the Indemnitee's reasonable costs of
investigation and cooperation. However, the Indemnitee shall have the right to
employ separate counsel and to control the defense of an Action (and the
Indemnifying Party shall bear the reasonable fees, costs, and expenses of such
counsel) if:

                  (i) the use of the counsel chosen by the Indemnifying Party
would present such counsel with a conflict of interest;

                                       72

<PAGE>

                  (ii) the actual or potential defendants in, or targets of,
such Action include both the Indemnifying Party and the Indemnitee, and the
Indemnitee reasonably concludes that there may be legal defenses available to it
that are different from or additional to those available to the Indemnifying
Party (in which case the Indemnifying Party shall not have the right to assume
the defense of such Action on the Indemnitee's behalf);

                  (iii) the Indemnifying Party does not employ counsel
reasonably satisfactory to the Indemnitee to represent the Indemnitee within a
reasonable time after the Indemnitee's notice of such Action; or

                  (iv) in the reasonable opinion of counsel to the Indemnitee,
the claim could result in the Indemnitee becoming subject to injunctive relief
or relief other than the payment of Losses that could have a materially adverse
effect on the ongoing business of the Indemnitee; provided, however, that in no
event shall the Indemnifying Party be obligated to bear the fees, costs and
expenses of more than one (1) separate counsel for all of the other Party's
Indemnitees in such Action.

            (c) Cooperation. The Indemnitee shall cooperate fully with the
Indemnifying Party and its legal representatives in the investigation and
defense of an Action. The Indemnifying Party shall keep the Indemnitee informed
on a reasonable and timely basis as to the status of such Action (to the extent
the Indemnitee is not participating in the defense of such Action) and conduct
the defense of such Action in a prudent manner.

            (d) Settlement. If an Indemnifying Party assumes the defense of an
Action, no compromise or settlement of such Action may be effected by the
Indemnifying Party without the Indemnitee's written consent (which consent shall
not be unreasonably withheld or delayed), unless (i) there is no finding or
admission of any violation of law or any violation of the rights of any person
and no effect on any other claims that may be made against the Indemnitee, (ii)
the sole relief provided is monetary damages that are paid in full by the
Indemnifying Party, and (iii) the Indemnitee's rights under this Agreement are
not adversely affected. If the Indemnifying Party fails to assume defense of an
Action within a reasonable time, the Indemnitee may settle such Action on such
terms as it deems appropriate with the consent of the Indemnifying Party (which
consent shall not be unreasonably withheld), and Indemnifying Party shall be
obligated to indemnify the Indemnitee for such settlement as provided in this
Section 12.

      12.4 Indemnification Payment Adjustments

            (a) Insurance Proceeds Or Other Recovery. The amount of any Losses
for which indemnification is provided under this Section 12 shall be reduced by
the insurance proceeds received and any other amount recovered, if any, by the
Indemnitee with respect to any Losses. An Indemnitee shall mitigate, to the
extent such mitigation

                                       73

<PAGE>

does not otherwise harm such Indemnitee or is otherwise inconsistent with this
Section 12, any Losses for which indemnification is sought hereunder and, to the
extent such Losses are covered by Indemnitee's insurance, shall pursue an
insurance claim relating to such Losses.

            (b) Refund. If an Indemnitee receives a payment pursuant to this
Section 12 and subsequently receives insurance proceeds or other amounts with
respect to the same Losses, the Indemnitee shall pay to the Indemnifying Party
an amount equal to the difference (if any) between: (i) the sum of the insurance
proceeds received, other amounts received, and the indemnification amount
received from the Indemnifying Party pursuant to this Section 12 and (ii) the
amount necessary to fully and completely indemnify and hold harmless the
Indemnitee from and against such Losses. However, in no event shall such refund
ever exceed the Indemnifying Party's payment to the Indemnitee under this
Section 12.

      12.5 Indemnification Payment. Any amount owed by an Indemnitee to a Third
Person, for which the Indemnifying Party has an obligation under this Section 12
to indemnify, shall be due from the Indemnifying Party to the Third Person,
whether upon entry of judgment, upon settlement, or otherwise.

      12.6 Survival. The provisions of this Section 12 shall survive any
termination or expiration of this Agreement. Each Indemnitee's rights under this
Section 12 shall not be deemed to have been waived or otherwise affected by such
Indemnitee's waiver of the breach of any obligation, agreement, condition,
covenant, representation, or warranty contained in, or made pursuant to, this
Agreement, unless such waiver expressly (and in writing) also waives any or all
of the Indemnitee's rights under this Section 12.

13. TERM AND TERMINATION

      13.1 Term. This Agreement shall commence on the Effective Date and shall
be in full force and effect until the expiration of the last to expire Royalty
Term or, if terminated earlier pursuant to Section 13.3 or Section 13.4, until
the effective date of termination as provided in Section 13.3 or Section 13.4
(the "TERM"). The Parties shall be obligated to continue to perform all of their
obligations, and enjoy all of their rights, under this Agreement until the end
of the Term.

      13.2 Condition Precedent

Diligent Efforts to satisfy any applicable requirements under the HSR, and the
regulations promulgated thereunder, including by making an initial HSR filing no
later than five (5) Business Days after the Execution Date. This Agreement will
not be

                                       74

<PAGE>

effective until the date ("EFFECTIVE DATE") of either satisfaction of any such
requirements and the expiration or termination of all applicable waiting periods
(including any extensions thereof), or when AstraZeneca determines and notifies
AGIX in writing that no filings are required thereunder. All obligations,
rights, duties and liabilities under this Agreement (except those contained in
this Section and Sections 10, 14 and 15 of this Agreement) are subject to such
date.

            (b) Cooperation. Each Party shall cooperate with the other Party in
the prompt preparation, execution and filing of all documents that are required
or permitted to be filed pursuant to HSR, and to notify the other Party upon
receipt of any formal or informal requests for information from any antitrust
agency in connection with any filings under HSR. Each Party shall bear its own
costs with respect thereto (including the filing fees for HSR, which shall be
paid by AstraZeneca).

            (c) Termination Right. If the Effective Date has not occurred within
six (6) months after the Execution Date, notwithstanding that each Party having
fulfilled its obligations under this Section, either Party has the right to
terminate this Agreement without liability to the other Party by notice in
writing with immediate effect.

      13.3 Termination by AstraZeneca

            (a) ARISE

                  (i) The JDC shall determine, within five (5) days after
delivery by AGIX to the JDC of ARISE Results, whether such ARISE Results are
complete and final ("FINAL ARISE RESULTS"). If the JDC is unable to agree
unanimously as to whether such ARISE Results constitute Final ARISE Results
within such five (5) day period, the matter shall be immediately referred to the
JMC and, if the JMC cannot promptly resolve the matter, the officers set forth
in Section 14.1(b), or their designee, for attempted resolution by good faith
negotiations. In the event that the JMC and, if necessary, the designated
executive officers, do not resolve the matter within thirty (30) days, the ARISE
Results as submitted by AGIX shall for purposes of this Agreement be considered
Final ARISE Results.

                  (ii) AstraZeneca shall have the right, in its sole discretion
and for any reason, to terminate this Agreement in its entirety, upon ninety
(90) days' prior written notice, at any time during the [****] period following

in section 13.3(a)(i).

            (b) Approvable Letter. AstraZeneca shall have the right, in its sole
discretion and for any reason, to terminate this Agreement in its entirety, upon

<PAGE>

information or materials required, or specified conditions, that are reasonably
likely to require, in order to obtain U.S. NDA Approval, either (i) more than
twenty-four (24) months from receipt of such Approvable Letter to submit such
additional information or materials to meet such condition, or (ii) reasonable
out-of-pocket costs paid to Third Parties (whether or not AstraZeneca were to
actually engage Third Parties for such activities or perform them internally) of
more than [****] by AstraZeneca for items or activities not included in the
Initial Development Plan, unless AGIX agrees to pay any amounts in excess of
such [****].

            (c) Additional Studies. AstraZeneca shall have the right in its sole
discretion and for any reason, upon ninety (90) days' prior written notice, to
terminate this Agreement in its entirety if the FDA, in an Approvable Letter
subsequent to the Approvable Letter referred to in Section 13.3(b), requires
information or data from additional studies not contemplated in the Initial
Development Plan, where the reasonable out-of-pocket costs paid to Third Parties
(whether or not AstraZeneca were to actually engage Third Parties for such
activities or perform them internally) for such additional information or
studies, when added to the cost to AstraZeneca of complying with the
requirements described in Section 13.3(b), is reasonably likely to exceed
[****], unless AGIX agrees to pay any amounts in excess of such [****].

            (d) Elective Termination. AstraZeneca shall have the right, in its
sole discretion and for any reason, to terminate this Agreement in its entirety,
at any time during the one-year period following the third annual anniversary of

notice to AGIX delivered at any time during such one-year period.

      13.4 Termination for Material Breach or Bankruptcy

            (a) Breach. If a Party materially breaches any material term of this
Agreement, the other Party may terminate this Agreement or any part thereof as
specifically permitted by this Agreement, effective ninety (90) days after
providing written notice to the breaching Party (or, in the case of a breach of
the diligence obligation by AstraZeneca provided for in Section 5, one hundred
and eighty (180) days or, if the breach of the diligence obligations are
referred to arbitration under Section 14, as specified by the Arbitration Panel
under Section 14.4), if within that time the breaching Party fails to cure its
material breach and the non-breaching Party does not withdraw its termination
notice.

            (b) Tolling of Time Periods. In the event that a Party initiates
arbitration proceedings pursuant to Section 14 during the ninety (90) day cure
period set forth in Section 13.4(a), such ninety (90) day period shall be
extended during the pendency of any dispute resolution proceedings under Section
14 (i.e., until the Arbitration Panel issues a final decision) with respect to
such termination notice.

            (c) Bankruptcy. Either Party may terminate this Agreement if (i) the
other Party files in any court or agency pursuant to any statute or regulation

trustee of a Party or of its assets, (ii) the other Party proposes a written

                        (E) all material information, and any other information

      AGIX a license in all of AstraZeneca's interest in and to Joint Inventions
      and Joint Patents necessary or useful for the Development, Manufacture or
      Commercialization of the Compound and/or Products in the Field. In the
      event of such election, the Parties shall negotiate in good faith
      commercially reasonable terms for such license; provided, however, that

      If the Parties do not agree upon the terms of such

                  (vi) Until such time, if at all, that AstraZeneca assigns this
Agreement and other assets to AGIX under Section 4.3 of the Transition Services

new suppliers;

                  (vii) In the event that AstraZeneca supplies Product and/or

termination;

                  (viii) AGIX may elect to acquire an exclusive, royalty bearing

                  (ix) In the event that, at the time of termination, there is a
Combination Product in Development that contains an Exclusive Market Product, or

Section 5.2.

                  (iv) The obligations of the Parties under Sections 2, 3, 4, 5

the other Party at no cost, such additional appropriate technology transfer,
transition assistance and post-termination services not otherwise specified in
this Section 13, including without limitation, Manufacturing services and the
continuation of the Supply of Product, necessary or useful for such other Party
to effectuate its rights hereunder.

            (e) Return of Confidential Information. Upon expiration or

rights that either Party may have arising under applicable law or equity.

      13.7 Rights in Bankruptcy. All rights and licenses granted under or
pursuant to this Agreement by AGIX and AstraZeneca are, and shall otherwise be
deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code,
licenses of rights to "Intellectual Property" as defined under Section 101 of
the U.S. Bankruptcy Code. The Parties agree that the Parties, as licensees of
such rights under this Agreement, shall retain and may fully exercise all of
their rights and elections under the U.S. Bankruptcy Code. The Parties further
agree that, in the event of the commencement of a bankruptcy proceeding by or
against a Party under the U.S. Bankruptcy Code, the Party hereto that is not a
Party to such proceeding shall be entitled to a complete duplicate of (or
complete access to, as appropriate) any such intellectual property and all
embodiments of such intellectual property, which, if not already in the
non-subject Party's possession, shall be promptly delivered to it (a) upon any
such commencement of a bankruptcy proceeding upon the non-subject Party's
written request therefor, unless the Party subject to such proceeding continues

behalf of the Party subject to such proceeding upon written request therefor by
the non-subject Party.

      13.8 Accrued Rights and Obligations; Survival. Termination of this
Agreement by a Party pursuant to Section 13.4 shall not be a Party's sole remedy
for a material breach of this Agreement, but shall be in addition to any other
rights or remedies of a

                                       81

<PAGE>

Party under this Agreement. Termination or expiration of this Agreement shall
not affect any accrued rights or surviving obligations of the Parties. The
provisions of Sections 3.2(e), 9.1, 9.7(a), 10.1, 10.2, 11.10, 11.11, 13.1,
13.3, 13.4, 13.5, 13.6, 13.7, 13.8 and Sections 12, 14 and 15 shall survive the

      14.1 Procedure

            (a) Scope. Any dispute arising out of or relating to this Agreement
(a "DISPUTE") is subject to the provisions of this Section 14; provided,
however, that Disputes regarding the scope, validity or enforceability of
Patents are excluded from the scope of this Section 14, ("Excluded Disputes")
and such Excluded Disputes shall be submitted to a court of competent
jurisdiction.

            (b) Good Faith Negotiations. In the event of a Dispute that is not
an Excluded Dispute, either Party may provide written notice of the Dispute to
the other, in which event the Dispute shall be referred to the executive

            For AGIX: President and Chief Executive Officer of AGIX

            For AstraZeneca: Chief Executive Officer of AstraZeneca PLC In the
event the designated executive officers do not resolve such Dispute within the
allotted fourteen (14) days, either Party may within thirty (30) days of the end
of the fourteen (14) day period invoke the provisions of Section 14.2
hereinafter.

      14.2 Alternative Dispute Resolution. Following the failure of settlement
efforts pursuant to Section 14.1, any Dispute other than an Excluded Dispute ,
shall be subject to binding arbitration ("ADR") in the manner described below:

            (a) Request. A Party shall initiate an ADR to resolve a Dispute by
providing written notice (the "ADR REQUEST") to counsel for the other Party, the
issues to be resolved by the ADR.

            (b) Issues Covered. Within ten (10) Business Days after the receipt
of the ADR Request, the other Party may, by written notice to the counsel for
the Party initiating ADR, add additional issues to be resolved, if such issues
had previously been addressed by the Executive Officers of the Parties pursuant
to Section 14.1. Issues that had not previously been addressed by the Executive
Officers of the Parties pursuant to Section 14.1, and issues not added within
(ten) 10 Business Days of receipt of the ADR

                                       82

<PAGE>

Request, may not be subjects of the ADR invoked by the ADR Request and must be
resolved, if at all, by initiation of separate Dispute proceedings.

      14.3 Arbitration Procedure. The ADR shall be conducted pursuant to the
JAMS Rules then in effect, except that notwithstanding those rules, the
following provisions shall apply to the ADR hereunder:

            (a) Panel. The arbitration shall be conducted by a panel of three
(3) arbitrators (the "ARBITRATION PANEL"). The Arbitration Panel shall be
selected from a pool of retired independent federal judges to be presented to
the Parties by JAMS.

            (b) Process. The time periods set forth in the JAMS rules shall be
followed, unless a Party can demonstrate to the Arbitration Panel that the
complexity of the issues, urgency of the Dispute or other reasons warrant
extension or contraction of one or more of the timetables. For good cause shown,
the Arbitration Panel may extend or contract such timetables, but in no event
shall the timetables be extended so that the ADR proceeding extends more than
eighteen (18) months from the date of the ADR Request. Within such time frames,
each Party shall have the right to conduct such discovery as would be permitted
by the Federal Rules of Civil Procedure. The Arbitration Panel shall not award
punitive damages to either Party and the Parties shall be deemed to have waived
any right to such damages. The Arbitration Panel shall in rendering its
decision, apply the substantive law of the State of New York, excluding its
choice of law rules that would require the application of the laws of another
jurisdiction, except that the interpretation of and enforcement of this Section
14 shall be governed by the Federal Arbitration Act. The Arbitration Panel shall
apply the Federal Rules of Evidence to the hearing. In the event that
arbitration is initiated by AGIX, the hearing shall convene in New York, New
York. In the event that arbitration is initiated by AstraZeneca, the hearing
shall convene in Atlanta, Georgia. The fees of the Arbitration Panel and JAMS
shall be paid by the losing Party, which shall be designated by the Arbitration
Panel. If the Arbitration Panel is unable to designate a losing Party, it shall
so state and the fees shall be split equally between the Parties.

            (c) Remedies. The Arbitration Panel is empowered to award any remedy
allowed by law or equity, including money damages, prejudgment interest and
attorneys' fees, and to grant final, or complete relief, but excluding punitive
damages. By agreeing to arbitration, the Parties do not intend to deprive any
court of its jurisdiction to issue a pre-arbitral injunction, pre-arbitral
attachment, or other order in aid of arbitration proceedings and the enforcement
of any award. Without prejudice to such provisional remedies as may be available
under the jurisdiction of a court, the Arbitration Panel shall have full
authority to grant provisional remedies (including without limitation injunctive
relief) or to order any Party or Parties to request that a court modify or
vacate any temporary or preliminary relief issued by that court, and to award
damages for the failure of any Party to comply with the Arbitration Panel's
orders to that effect.

                                       83

<PAGE>

            (d) Fees. Except as set forth in Section 14.3(b) above, each Party
shall bear its own legal fees and expenses against the Party losing the ADR
unless it believes that neither Party is the clear loser, in which case the
Arbitration Panel shall divide such fees, costs and expenses according to the
Arbitration Panel's sole discretion.

            (e) Confidentiality. The ADR proceeding shall be confidential and
the Arbitration Panel shall issue appropriate protective orders to safeguard
each Party's Confidential Information. Except as required by law, no Party shall
make (or instruct the Arbitration Panel to make) any public announcement with
respect to the proceedings or decision of the Arbitration Panel without prior
written consent of each other Party. The existence of any Dispute submitted to
ADR, and the award, shall be kept in confidence by the Parties and the
Arbitration Panel, except as required in connection with the enforcement of such
award or as otherwise required by applicable law.

            (f) Judicial Enforcement. The Parties agree that judgment on any
arbitral award issued pursuant to this Section shall be entered in the United
States District Court for the Northern District of Georgia.

            (g) Governing Law. This Agreement shall be governed and construed in
accordance with the laws of the State of New York, except for any of its choice
of law rules that would require the application of the laws of another
jurisdiction.

      14.4 Special Rules for Disputes Concerning Diligence Covenant. In
rendering any decision involving any Dispute relating to or arising out of
Section 5, the Arbitration Panel shall specify:

            (a) the requirements, if any, considered necessary or appropriate
for a Party to comply with Section 5, and

            (b) the deadline or deadlines for taking steps required for any such
compliance, which deadlines may be shorter or longer than the one hundred eighty
(180) day cure period specified in Section 13.4(a).

15. MISCELLANEOUS

      15.1 Standstill. [****]

      15.2 Termination of Certain Rights Upon AGIX Change of Corporate Control.
Notwithstanding anything else in this Agreement to the contrary, unless
otherwise specified by AstraZeneca within three (3) months after a Change of
Corporate Control involving AGIX, the following provisions of this Agreement
shall terminate:

-------
[****] indicates that certain confidential information contained in this
document has been omitted pursuant to a request for confidential treatment and
filed separately with the Securities and Exchange Commission.

                                       84

<PAGE>

            (a) AGIX's right to participate in the JDC, JMC, Global
Commercialization Team, U.S. Commercialization Team, and any other subcommittees
or working groups established pursuant to Section 6.1, except as provided in
Section 15.2(b);

            (b) AGIX and/or its successor shall continue to participate fully on
the IPC, except that the IPC shall no longer have decision-making jurisdiction
over all Licensed Patents, but instead shall have such jurisdiction only over
Other AGIX Patents, with AstraZeneca having unilateral control over Prosecution,
enforcement and defense of AGIX Compound Patents (and the rest of IPC
jurisdiction and control would remain unaffected);

            (c) some or all of AGIX's rights as described in the Co-Promotion
Agreement, to the extent and as provided therein. The Co-Promotion Agreement
further provides that, under certain circumstances described herein, AstraZeneca
may, following an AGIX Change of Corporate Control, object under certain
circumstances to AGIX being permitted to continue to co-promote the Product; and

            (d) AstraZeneca shall assume control of Prosecution, enforcement and
defense of all AGIX Compound Patents. AGIX shall cooperate in providing to
AstraZeneca all information, assistance, assignments and other support
reasonably requested to assist AstraZeneca in assuming such control.

      15.3 Assignment. This Agreement shall inure to the benefit and be binding
upon each Party, its successors and assigns, except as provided in Section 15.2.
The Agreement may not be assigned or otherwise transferred, nor, except as
expressly provided hereunder, may any right or obligation hereunder be assigned
or transferred by either Party without the prior written consent of the other
Party, provided, however, that either Party may, without such consent, assign
the Agreement and its rights and obligations hereunder (i) to an Affiliate,
provided such Affiliate has the financial resources to perform the obligations
of this Agreement in the reasonable judgment of the other Party or (ii) in
connection with the transfer or sale of all or substantially all of its assets
or business to which this Agreement relates, or in the event of its merger or
consolidation or change in control or similar transaction, or a sale of all or
substantially all the pharmaceutical business assets of the Party; and provided
further, that AGIX or an Affiliate of AGIX shall be permitted to sell, assign or
transfer the right to receive Royalties owed by AstraZeneca to AGIX pursuant to
Section 8 to one or more Third Parties, and shall be permitted in connection
with any such sale, assignment or transfer, to assign the right to receive
reports and audit rights pursuant to Section 8, but not any other rights
hereunder, except to the extent the Parties otherwise agree in writing, to such
Third Party or Third Parties. Any attempted assignment not in accordance with
this Section 15.3 shall be void.

                                       85

<PAGE>

      15.4 Force Majeure. Neither Party shall be liable for any delay or failure
of performance to the extent such delay or failure is caused by circumstances
beyond its reasonable control and that by exercise of due diligence it is unable
to prevent, provided that the Party claiming excuse immediately notifies the
other Party and uses and continues to use commercially reasonable efforts to
overcome the same.

      15.5 Further Assurances. The Parties intend that this Agreement contain
all consents, licenses and authorizations from one Party to the other necessary
to enable each Party to perform its obligations hereunder. In the event any
further such consents, licenses or authorizations are necessary, each Party
agrees to take such further actions and execute such further agreements as may
be reasonably necessary to carry out the intent and purposes of this Agreement.

      15.6 Severability. The provisions of this Agreement are severable. If any
item or provision of this Agreement shall to any extent be invalid or
unenforceable, the remainder of this Agreement shall not be affected thereby,
and each term and provision of this Agreement shall be valid and shall be
enforced to the fullest extent permitted by law. The Parties will use diligent
good faith efforts to revise this Agreement as and to the extent reasonably
necessary to effectuate their original intent and purpose under this Agreement.

      15.7 Notices. All notices hereunder shall be in writing and shall be
delivered personally, sent for next day delivery by internationally recognized
courier service or transmitted by facsimile (transmission confirmed), with

      15.8 Jurisdiction and Venue. In connection with any Dispute arising
hereunder or in connection with the subject matter hereof that is not settled in
accordance with Sections 14.1 and 14.2, each of the Parties hereby consents to
the non-exclusive jurisdiction and venue of the U.S. federal courts located
within the Southern District of New York. Each Party hereby irrevocably waives
any right that it may have to assert that any such court lacks jurisdiction,
other than the grounds that such Dispute is covered by Section 14, or that such
forum is not convenient.

      15.9 Affiliates. Without limiting the generality of the foregoing, any
obligations of AstraZeneca may be performed by any of AstraZeneca's Affiliates,
including but not limited to AstraZeneca, and such obligations will be deemed
satisfied upon full and complete performance by such Affiliate as specified in
this Agreement.

      15.10 Entire Agreement. This Agreement and the Related Agreements, herein
and therein, including any exhibits expressly named and referenced herein and
therein, constitute the entire agreement and understanding of the Parties and
supersede any prior agreements or understandings relating to the subject matter
hereof, including the Confidential Disclosure Agreement between AGIX and
AstraZeneca Pharmaceuticals LP dated as of March 12, 2003. Any modification of
this Agreement shall be effective only to the extent it is reduced to writing
and signed by a duly authorized representative of each Party hereto.

      15.11 Headings. The captions to the several Sections and subsections
hereof are not a part of this Agreement, but are merely for convenience to
assist in locating and reading the several Articles and Sections hereof.

      15.12 Independent Contractors. It is expressly agreed that AGIX and
AstraZeneca shall be independent contractors and that the relationship between
the two

                                       87

<PAGE>

Parties shall not constitute a partnership, joint venture or agency. Neither
AGIX nor AstraZeneca shall have the authority to make any statements,
representations or commitments of any kind, or to take any action, which shall
be binding on the other, without the prior consent of the other Party.

      15.13 Waiver. The failure on the part of a Party to exercise or enforce
any rights conferred upon it hereunder shall not be deemed to be a waiver of any
such rights nor operate to bar the exercise or enforcement thereof at any time
or times hereafter.

      15.14 No Third Party Beneficiaries. This Agreement is neither expressly
nor impliedly made for the benefit of any Person other than the Parties.

      15.15 Cumulative Remedies. No remedy referred to in this Agreement is
intended to be exclusive, but each shall be cumulative and in addition to any
other remedy referred to in this Agreement or otherwise available under law.

      15.16 Counterparts. The Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

      15.17 Waiver of Rule of Construction. Each Party has had the opportunity
to consult with counsel in connection with the review, drafting and negotiation
of this Agreement. Accordingly, the rule of construction that any ambiguity in
this Agreement shall be construed against the drafting Party shall not apply.

      3.1. Strategic Targeting Plan

            (a) Within one hundred twenty (120) days after delivery by the
Company to AstraZeneca of the Final ARISE Results, the U.S. Commercialization
Team (which shall include representatives of the Company pursuant to the
Collaboration Agreement), shall begin developing a Strategic Targeting Plan for
the four (4) month period following the Approval Date. Such Strategic Targeting
Plan shall be finalized no later than thirty (30) days prior to the Anticipated
Approval Date. Any Strategic Targeting Plan [****], with a predominant emphasis
on cardiologists, [****].

            (b) Not less than thirty (30) days prior to the beginning of each
Calendar Trimester during the Funding Term and the Detail Funding Term, if any,
the U.S. Commercialization Team (which shall include representatives of the
Company pursuant to the Collaboration Agreement), shall finalize an updated
Strategic Targeting Plan for the next succeeding Calendar Trimester.

            (c) During the course of preparation of any Strategic Targeting Plan
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,

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 [****].

members of the Sales Force (including other managers), as determined by the
Sales Operations Group within ninety (90) days prior to the Anticipated Approval

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

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
upon monthly performance data that AZ provides the Company, the Company shall

the Funding Term, the Company Sales Force shall be dedicated exclusively to the
Promotion of the Products.

      3.5. Expertise of the Company

            The Company shall employ its expertise, best professional judgment,
and where applicable its working relationships with the Target Prescribers, for
the purpose of having Company Representatives Detail the Products consistent
with the Strategic Targeting Plan.

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
management personnel to conduct annual field observations with AZ'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
shall be granted by each Party upon reasonable advance notice from such other
Party.

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-

<PAGE>

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

makes available to AZ Representatives for similarly valued specialists, as

            AZ shall make Product samples available to the Company for use by
Company Representatives in Detailing the Products at AZ's sole cost during the
Term. Such Product samples shall be of the same quality and quantity on a per
Representative basis as the Product samples that AZ makes available to the AZ

Targeting Plan. The U.S. Commercialization Team shall determine sampling
strategy, including whether sample-send or sample-carry methods are utilized;
provided that any such determination shall be applied consistently with the

Representatives shall (i) use the Information Technology to order Product
samples from AZ and to maintain accurate records of use and distribution of
Product samples; and (ii) ensure that not less than [****] (or whatever lower
amount of samples required to be provided by AZ Representatives for the Product)
are provided to Target Prescribers in accordance with the Strategic Targeting
Plan and that samples are provided to non-Target Prescribers only in such cases
the Company reasonably believes that such deliveries are likely to result in
increased sales of the Products. The Company shall comply with all requirements

Company shall use Commercially Diligent Efforts to ensure that Company
Representatives carry only those quantities of Product samples reasonably needed
for a specific period; provided, however, that the Company shall, at AZ's
reasonable request, audit the inventory of any Company Representative whose
supply of Product samples is materially inconsistent with such Company
Representative's need for such Product samples. In no event, however, shall any
Company Representative carry more than a five (5) day supply of samples in his

                                      -22-

Funding Term to reflect estimated costs for the next Calendar Year. All

            (b) Not more than thirty (30) days prior to the beginning of each
month during the Funding Term, the Company shall provide AZ with an invoice,
using the form provided in Schedule 6.1A attached hereto, of the estimated

Calendar Quarter during the Funding Term, the Company shall provide AZ with a
statement, using the form provided in Schedule 6.1B attached hereto, of any

            (d) AZ shall pay to the Company the amounts reflected on the
invoice(s) described in Section 6.1(b), and, if any statement provided to AZ
pursuant to Section 6.1(c) shows an amount due to the Company, the amounts

AZ pursuant to Section 6.1(b). In the event that the amount due to AZ exceeds
the amount due to the Company under the next invoice, the Company shall remit to
AZ, by check or wire transfer within thirty (30) days, such excess amount.

            (e) Schedule 6.1A and Schedule 6.1B shall be amended for any

            (b) The Company shall submit an invoice to AZ for all payments due
in respect of any such bonus or incentive payment promptly after any obligation
to make such payment has accrued during the Funding Term. AZ shall pay to the
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,

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,

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
obligations under this Agreement; provided, however, that the Company shall not
be required to maintain any receipts, invoices and other proof of expenditures
described in this Section 6.4(a) for more than three (3) years. Any adjustment
necessary under this section shall be made pursuant to Section 6.1(c).

            (b) Should AZ discover information indicating, in its opinion, an
inaccuracy in the calculation of the number of Calls or Details, AZ shall so
notify the Company in writing thereof (and shall set out its preliminary
conclusions in reasonable

public accounting firm selected by each Party's certified public accountants or
to such other Person as the Parties shall mutually agree (the "Arbitrator"). The
decision of the Arbitrator shall be final, and the losing Party shall bear all
of the costs and expenses of such arbitration, including the prevailing Party's
reasonable attorneys' fees.

            (d) Upon reasonable advance notice to the Company, AZ shall be
entitled, to the extent permitted by law and the Company's privacy policies, at
its expense, to have access to the Company's books and records relating to the
Company's compliance with Applicable Laws and the Corporate Integrity Agreement.
Such books and records shall include any policies and procedures concerning
compliance with Applicable Laws, and records of any investigations and remedial
and disciplinary actions taken to address material violations of Applicable
Laws. AZ may exercise this audit right no more frequently than once in each
twelve month period, unless AZ reasonably believes that the Company is not
complying with its obligations under this Agreement; provided, however, that the
Company shall not be required to maintain any books and records described in
this Section 6.4(d) for more than three (3) years.

      6.5. Amendments

            In the event that AZ adds to or substitutes the Secondary Product to
be Promoted by Company hereunder, the aggregate amounts of compensation payable
under Sections 6.1 and 6.2 hereof shall not change, but the methodology of
determining such compensation may be modified as agreed by the parties in
writing and certain additional provisions of this Agreement may require mutually
agreed upon modification, including the Strategic Targeting Plan.

      6.6. All Inclusive

obligation to pay the Company for its services under this Agreement. Except as
otherwise expressly provided in this Agreement, the Company shall be responsible
for all of its costs and expenses incurred in connection with the performance of

            (a) Confidential Information. All Information disclosed by one Party
to the other Party hereunder, including the terms of this Agreement
("Confidential Information"), shall be maintained in confidence by the receiving
Party and shall not be disclosed to any Person who is not a Party or an
Affiliate of such Party, or used for any purpose except to exercise its rights
and perform its obligations under this Agreement without the prior written
consent of the disclosing Party, except to the extent that the receiving Party
can demonstrate by competent written evidence that such Information:

                  (i) is known by the receiving Party at the time of its receipt
and, not through a prior disclosure by the disclosing Party, as documented by
the receiving Party's business records;

                  (ii) is in the public domain other than as a result of any
breach of this Agreement by the receiving Party;

                  (iii) is subsequently disclosed to the receiving Party on a
non-confidential basis by a Third Party who may lawfully do so; or

                  (iv) is independently discovered or developed by the receiving
Party without the use of Confidential Information provided by the disclosing
Party, as documented by the receiving Party's business records.

            (b) Return of Confidential Information Upon Expiration or
Termination of Agreement. Within thirty (30) days after any expiration or
termination of this Agreement, each Party shall destroy (and certify to the
other Party such destruction) or return such Confidential Information provided
by the other Party as the other Party reasonably requests be destroyed or
returned; provided, however, that (i) the foregoing obligation shall not apply
to any matter of Confidential Information otherwise provided for in this
Agreement; and (ii) each Party may retain a single copy of the Confidential

its ongoing rights and responsibilities regarding the Confidential Information.

      12.2. Permitted Disclosures

            (a) Permitted Disclosure. Each Party may disclose Confidential
Information provided by the other Party without such other Party's written
consent to the extent such disclosure is reasonably necessary in the following
instances:

                  (i) disclosure to governmental or other regulatory agencies in
order to obtain or maintain intellectual property protection (such as
Trademarks) and to obtain, maintain or amend any Regulatory Materials regarding
a Product or satisfy any other regulatory obligation regarding a Product, but
such disclosure may be only to the extent reasonably necessary to obtain or
maintain intellectual property protection or obtain, maintain or amend such
Regulatory Materials;

                  (ii) complying with applicable court orders or governmental
regulations, including without limitation rules or regulations of the Securities
and Exchange Commission, or by rules of the National Association of Securities
Dealers, any securities exchange or NASDAQ; provided, however, that the
receiving Party shall first have given notice to the other Party hereto in order
to allow such Party the opportunity to seek confidential treatment of the
Confidential Information;

                  (iii) disclosure to consultants, agents or other Third Parties
solely to the extent required to accomplish the purposes of this Agreement;
provided however that such Third Parties agree to be bound by confidentiality
and non-use obligations at least equivalent in scope to those contained in this
Agreement.

            (b) Written Agreements. Each Party shall obtain written agreements
from each of its employees and consultants who perform work pursuant to this
Agreement, which agreements shall obligate such persons to similar obligations
of confidentiality and to assign to such Party all inventions made by such
persons during the course of performing such work. Execution of the Service
Agreement shall be considered satisfaction of this obligation. Each Party will
notify the other Party promptly upon discovery of any unauthorized use or
disclosure of the Confidential Information of the other Party.

            (c) Required Disclosure. If a Party is required by judicial or
administrative process to disclose Confidential Information that is subject to
the non-disclosure provisions of Section 12.1, such Party shall promptly inform
the other Party of the disclosure that is being sought in order to provide the
other Party an opportunity to challenge or limit the disclosure obligations,
provided that such Party's obligations to comply with Applicable Laws shall not
be affected by such obligations. Confidential Information that is disclosed by
judicial or administrative process shall remain otherwise subject to the
confidentiality and non-use provisions of Section 12.1, and the Party

                                      -33-

<PAGE>

disclosing Confidential Information pursuant to law or court order shall take
all reasonable steps necessary, including without limitation obtaining an order
of confidentiality, to ensure the continued confidential treatment of such
Confidential Information.

      12.3. Use of Name

            Neither Party shall use the name of the other Party, without the
prior written approval of the other Party, for any purpose other than informing
employees who need to know about this Agreement; provided, however, that
AstraZeneca or its Affiliates may, without the Company's prior written approval,
use the Company's name on marketing materials that were developed by or under
the direction of the U.S. Commercialization Team or Global Commercialization

reports, prospectuses, public statements, educational and scientific
conferences, Promotional Materials, governmental filings and discussions with
public officials, securities analysts, investors and the media. However, subject

Party has advised is required by law or regulation or in response to requests
for a copy of this Agreement or related information by tax authorities.

anything else in this Section 14.2 to the contrary, (i) AZ shall not be
obligated to indemnify the Company for those Losses for which the Company has an
obligation to indemnify AZ pursuant to Section 14.3, as to which Losses each
Party shall indemnify the other to the extent of their respective liability for

                                      -36-

<PAGE>

      14.3. Company Indemnification

            The Company shall indemnify AZ, its Affiliates and their respective
directors, officers, employees and agents (the "AZ Indemnified Parties"), and
defend and save each of them harmless, from and against any and all Losses
incurred by any of them in connection with, arising from or occurring as a
result of (i) the breach by the Company of any of its obligations under this
Agreement (including this Section 14.3) or (ii) the breach or inaccuracy of any
representation or warranty made by the Company in this Agreement.
Notwithstanding anything else in this Section 14.3 to the contrary, (i) the
Company shall not be obligated to indemnify AZ for those Losses for which AZ has
an obligation to indemnify the Company pursuant to Section 14.2, as to which
Losses each Party shall indemnify the other to the extent of their respective
liability for such Losses; and (ii) the Company shall not be obligated to
indemnify any AZ Indemnified Party for any Losses that arise as a result of
gross negligence or willful misconduct on the part of any AZ Indemnified Party.

      14.4. Indemnification Procedure

            (a) Notice of Claim. The indemnified Party (the "Indemnified Party")
shall give the indemnifying Party (the "Indemnifying Party") prompt written
notice (an "Indemnification Claim Notice") of any Losses or discovery of facts
upon which such Indemnified Party intends to base a request for indemnification
under Section 14.2 or Section 14.3, but in no event shall the Indemnifying Party
be liable for any Losses that result from any delay in providing such notice.
Each Indemnification Claim Notice must contain a description of the claim and
the nature and amount of such Loss (to the extent that the nature and amount of
such Loss are known at such time). The Indemnified Party shall furnish promptly
to the Indemnifying Party copies of all papers and official documents received
in respect of any Losses.

            (b) Third Party Claims. The obligations of an Indemnifying Party
under this ARTICLE XIV with respect to Losses arising from claims of any third
party that are subject to indemnification as provided for in Section 14.2 or
Section 14.3 (a "Third Party Claim") shall be governed by and be contingent upon
the following additional terms and conditions:

                  (i) Control of Defense. At its option, the Indemnifying Party
may assume the defense of any Third Party Claim by giving written notice to the
Indemnified Party within thirty (30) days after the Indemnifying Party's receipt
of an Indemnification Claim Notice. The assumption of the defense of a Third
Party Claim by the Indemnifying Party shall not be construed as an
acknowledgment that the Indemnifying Party is liable to indemnify any
Indemnified Party in respect of the Third Party Claim, nor shall it constitute a
waiver by the Indemnifying Party of any defenses it may assert against any
Indemnified Party's claim for indemnification. Upon assuming the defense of a
Third Party Claim, the Indemnifying Party may appoint as lead counsel in the
defense of the Third Party Claim any legal counsel selected by the Indemnifying

                                      -37-

<PAGE>

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-

<PAGE>

                  (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

<PAGE>

            (b) Upon the effective date of termination of this Agreement
pursuant to Section 15.1, the Company shall promptly cease all Promotion of the
Products and promptly discontinue the use of any Product Trademarks. The
termination of this Agreement shall be without prejudice to any rights or
obligations of the Parties that may have accrued prior to such termination, and
the provisions of Sections 8.1 (with respect to the Company's obligation to
report to AZ), 14.2, 14.3, 14.4, 14.5 and Articles IX, X, XI, XII, XIII, XV and
XVI shall survive any termination of this Agreement. Except as otherwise
expressly provided herein, termination of this Agreement in accordance with the
provisions hereof shall not limit remedies which may otherwise be available in
law or equity.

            (c) Upon the effective date of expiration or termination of the
Funding Term or the Detail Funding Term pursuant to Section 15.2 or 2.1(c), the

this Agreement.

      15.4. Return of All Materials

            At the end of the Term, the Company shall promptly return to AZ all
Product samples, all equipment and materials, Promotional Materials, and

the control of, the Company or the Company Sales Force; provided the Company
shall have the right to purchase the lap top and Territory Management Devices
from AZ at their respective then fair market value.

      15.5. Continuation of Promotion of Secondary Product

            The Company would be permitted to continue to co-promote the

agreement of the Parties.

                                  ARTICLE XVI.
                                 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-

<PAGE>

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-

<PAGE>

            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.

liberally construed in order to carry out the intent of the Parties as nearly as
may be possible, and (b) the Parties shall use their best efforts to negotiate a

unenforceable, that is consistent with applicable law and accomplishes, as
nearly as possible, the original intention of the Parties with respect thereto.

provision of law that would render any provision hereof prohibited or
unenforceable in any respect.

remedies under this Agreement.

                               SERVICES AGREEMENT
                            (COMPANY EMPLOYEE MODEL)

      This Services Agreement ("Agreement") is made by and between AtheroGenics,
Inc. (the "Company") and ____________________________________ ("Employee").

      WHEREAS, the Company and Employee each acknowledge that Employee is an
employee of the Company;

      WHEREAS, Company has entered into a Co-Promote Agreement (the "AZ
Agreement") with AstraZeneca Pharmaceuticals LP ("AZ"); and

      NOW, THEREFORE, in consideration of the premises and mutual agreements
herein contained, and other good and valuable consideration (the receipt and
sufficiency of which are hereby acknowledged), and intending to be legally bound
hereby, the parties hereto agree as follows:

      1. General. The parties agree that the premises as set forth above are
incorporated within and made a part of this Agreement.

      2. Confidential Information

            (a) Employee acknowledges and agrees that he or she will have access
to, or become acquainted with, Confidential Information of the Company and AZ.
For the purposes of this Agreement, "Confidential Information" shall mean any
information of the Company and AZ, whether or not developed by Employee,
including but not limited to, information which relates to all ideas, designs,
methods, discoveries, improvements, products or other results of the services
provided pursuant to this Agreement and in connection with the AZ Agreement
("Services"), and trade secrets, product data and specifications, proprietary
rights, business affairs, product developments, customer information or employee
information.

            (b) Employee acknowledges and agrees that the Confidential
Information constitutes valuable trade secrets of the Company and AZ. Employee
shall keep all Confidential Information in confidence and shall not, at any
time, without the Company's prior written consent, disclose or otherwise make

      3. Work Product

            (a) Employee agrees that all works capable of copyright protection
that are created, in part or in whole, by him or her in connection with the
Services (the "Copyright Work Product") shall be considered "works made for
hire" within the meaning of the copyright laws of the United States and that the
Company is and shall be the sole author of the Copyright Work Product, and the
sole owner of all rights therein. If any of the Copyright Work Product is

                                       1

deemed not to be a "work made for hire," then Employee hereby assigns to the
Company all worldwide rights, title and interest in and to the Copyright Work
Product.

            (b) Employee further agrees that the Company shall be the sole owner
of all inventions, discoveries, concepts, ideas, methods, improvements or
results, including all patents, trade secret rights and any other proprietary
rights therein that are developed, written, conceived, reduced to practice or
made by him or her, either solely or jointly with others, in connection with the
Services (the "Other Work Product", collectively with Copyright Work Product,
the "Work Product") and hereby assigns to the Company all worldwide rights to
and title and interest in such Other Work Product.

            (c) Employee agrees to assign, and cause his or her successors and
assigns to assign, to the Company all rights in and to (i) any invention
developed, written, conceived, reduced to practice or made by him or her in
connection with the Services and (ii) all applications for registration of any
patent rights in any such invention worldwide, including all United States and
foreign letters patent and United States and foreign letters patent granted upon
any invention and all extensions, renewals and reissues thereof, and all rights
to claim priority on the basis of these applications. Employee also agrees, and
shall cause his or her successors or assigns to agree, to authorize the
Commission of the United States Patent Office and the officials of any foreign
country whose duty it is to issue patents on applications to issue all letters
patent for such inventions to the Company, its successors and assignees.

            (d) Employee agrees to (i) execute all documents and perform all
acts deemed necessary by the Company to evidence the Company's ownership of all
of the foregoing Work Product; and (ii) assist the Company in obtaining,
registering, maintaining and defending, at the Company's sole expense, all
patents, copyrights, trade secret rights and other proprietary rights in and to
the Work Product in any and all countries as may be determined by the Company.

            (e) Employee hereby irrevocably appoints the Company as his or her
attorney-in-fact for the purpose of executing such documents in his or her name.

      4. No Other Benefits. Employee acknowledges and agrees that he or she
shall not receive any employee benefits or any other compensation of any kind
from any entity other than the Company, but shall receive all compensation for
all services performed hereunder from the Company.

      5. Employee Representation. Employee represents and warrants to the
Company that Employee has not been debarred and is not subject to debarment
pursuant to Section 306 of the Federal Food, Drug, and Cosmetic Act, as amended,
or is the subject of a conviction described in such section. Employee agrees to
notify the Company in writing immediately if he or she is debarred or is the
subject of a conviction described in Section 306, or if any action, suit, claim,
investigation, or legal or administrative proceeding is pending or, to the best
of Employee's knowledge, is threatened, relating to the debarment or conviction
of Employee.

[IN THE EVENT THE EMPLOYEE EXECUTING THIS AGREEMENT IS EMPLOYED BY A CONTRACT
SALES ORGANIZATION, CONFORMING CHANGES TO THIS AGREEMENT WILL BE REQUIRED,
CONSISTENT WITH THE SERVICES AGREEMENT OF AZ FOR USE WITH CONTRACT SALES
ORGANIZATIONS.]
