Reasonable Efforts to negotiate an agreement with such Third Party which will be

Accredo Agreement, the New TheraCom Agreement or any such other Third Party
specialty pharmacy agreement shall not be materially disadvantageous to GSK or
its assignee relative to the terms of the Current Accredo Agreement or the
current TheraCom Agreement. GSK agrees that it shall negotiate in any of the New
TheraCom Agreement, the New Accredo Agreement or any such other Third Party
specialty pharmacy agreement a prompt payment discount to encourage payment of
invoices within approximately thirty (30) days.

          (c) Assignment of New Agreements.

               (i) Within five (5) Business Days after the execution of the New
Accredo Agreement, each Party will cause their respective authorized
representative to execute an assignment agreement with respect to the New
Accredo Agreement (the "New Accredo Agreement Assignment"), a copy of which is
attached hereto and incorporated herein as Exhibit D, pursuant to which as of
the Commencement Date, all rights and responsibilities of GSK under the New
Accredo Agreement will be assigned to Myogen, subject to the terms and
conditions of the New Accredo Agreement Assignment; and

               (ii) Within five (5) Business Days after the execution of the New
TheraCom Agreement, each Party will cause their respective authorized
representative to execute an assignment agreement with respect to the New
TheraCom Agreement (the "New TheraCom Agreement Assignment"), a copy of which is

conditions of the New TheraCom Agreement Assignment.

     Section 2.3 Territorial Limitation.

          (a) Myogen agrees that it will conduct its marketing, promotion,
advertisement, sale and distribution of Product solely in the Territory. Myogen
will not sell, market, promote, advertise or distribute Product in the GSK
Territory. Myogen will not knowingly sell or otherwise offer Product, directly
or indirectly, to any Customer for resale in the GSK Territory. Myogen will not,
directly or indirectly, sell or otherwise offer Product to any Customer that
Myogen reasonably believes is going to sell such Product, directly or
indirectly, in the GSK Territory, unless mutually agreed in writing upon by both
Parties. It is acknowledged by the Parties, however, that certain sales of
Product by Myogen to the United States Government, and its subdivisions thereof,
may result in Product being shipped to military bases and other government
installations that are in the GSK Territory and such sales will not constitute a
breach of this Agreement.

          (b) Subject to Applicable Law, Myogen will implement reasonable
safeguards so that Product is sold to Customers for resale only in the Territory
and not for resale in any country in the GSK Territory. If Myogen becomes aware
that any of its Customers has imported Product from the GSK Territory or
exported Product into the GSK Territory, or has reason to believe that a
Customer intends to import Product from the GSK Territory or export Product to
the GSK Territory, Myogen, to the extent permitted by Applicable Law, will take
Commercially Reasonable Efforts to cause such Customer to cease such
unauthorized import/export activities; provided, however, that nothing contained
in this Section 2.3(b) will obligate Myogen to take any action to comply with
this Section 2.3(b) which is greater than that taken by GSK with respect to the
Product prior to the Effective Date.

          (c) GSK agrees that it will, and will use Commercially Reasonable
Efforts to cause its Affiliates and their sublicensees to, conduct the
marketing, promotion, advertisement,

sale and distribution of Product solely in the GSK Territory. GSK will not
(except as expressly permitted by this Agreement or as required by Applicable
Law), and will use Commercially Reasonable Efforts to cause its Affiliates and
their sublicensees not to, sell, market, promote, advertise or distribute
Product in the Territory. GSK will not knowingly, and will use Commercially
Reasonable Efforts to ensure that its Affiliates and their sublicensees will not
knowingly, sell or otherwise offer Product, directly or indirectly, to any Third
Party in the GSK Territory for resale in the Territory. GSK will not, and will
use Commercially Reasonable Efforts to cause its Affiliates and their
sublicensees not to, directly or indirectly, offer Product to any Third Party
that GSK, such Affiliate or sublicensee reasonably believes is going to sell
such Product, directly or indirectly, in the Territory, unless mutually agreed
in writing by both Parties.

          (d) Subject to Applicable Law, GSK will, and will use Commercially
Reasonable Efforts to cause its Affiliates and their sublicensees to, implement
reasonable safeguards so that Product is sold by or on behalf of GSK, such
Affiliates or sublicensees only outside of the Territory ("GSK Territory") and
except as set forth in this Agreement, is not sold by or on behalf of GSK, its
Affiliates or their sublicensees in the Territory. If GSK becomes aware that any
Affiliate of GSK, its sublicensee or any of their Third Party purchasers has
imported Product from the Territory or exported Product into the Territory, or
has reason to believe that any Affiliate of GSK, its sublicensee or a Third
Party purchaser intends to import Product from the Territory or export Product
to the Territory, GSK, to the extent permitted by Applicable Law, will take
Commercially Reasonable Efforts to cause such Affiliate of GSK, sublicensee or
Third Party purchaser to cease such unauthorized import/export activities;
provided, however, that nothing contained in this Section 2.3(d) will obligate
GSK to take any action to comply with this Section 2.3(d) which is greater than
that taken by GSK with respect to Product prior to the Effective Date.

     Section 2.4 Restriction of Sub-Distributors. Without the prior written
consent of GSK, Myogen will not grant to any Third Party any rights to market,
promote, advertise, sell or distribute Product, and will not enter into any
agreement or arrangement with respect to co-promoting the Product. The foregoing
notwithstanding, Myogen may employ the services of a Third Party in the
acceptance of orders, generation of invoices and collection and management of
receivables with respect to Myogen's sales of Product in the Territory.

     Section 2.5 Compliance with Product Registration Resale in Same Packaging.
Myogen will not at any time do, and neither will Myogen permit its agents or
representatives to do, any act in violation of the Product Registration for any
of Product in the Territory. In the event that any filings are required to be
made with or approvals required to be obtained from applicable Governmental
Authorities in order to sell Product to Myogen or for Myogen to initiate
distribution, marketing, advertisement, sale or promotion of Product in the
Territory, the Parties will use Commercially Reasonable Efforts to ensure that
such filings and approvals are obtained or made as expeditiously as reasonably
practicable. Myogen will not alter in any manner any of the Product or its
packaging as sold to it by GSK hereunder and will resell Product without
alteration in the form sold to it by GSK.

     Section 2.6 No Manufacturing Rights Conveyed on Effective Date. Except for
Myogen's right to use the Trademarks pursuant to Section 3.3 hereof, no right or
license under any Trademark, or under any patent rights or know-how owned or
controlled by GSK or any of its Affiliates to make or have made Product is
granted under this Agreement to Myogen.

     Section 2.7 Non-Compete. During the Term, and for the consecutive [..**..]
period immediately succeeding the termination of this Agreement by GSK pursuant
to Section 12.2, neither Myogen nor any of its Affiliates will directly or
indirectly distribute, market, promote, detail, advertise or sell any product
[..**..] other than Product. During the Term, and for the consecutive [..**..]
period immediately succeeding the termination of this Agreement by Myogen
pursuant to Section 12.2, neither GSK nor any of its Affiliates will directly or
indirectly distribute, market, promote, detail, advertise or sell any product
[..**..] other than Product or Product Improvements not included within the
definition of Product pursuant to Section 4.5. The foregoing covenants shall not
restrict either Party or any Affiliate from obtaining rights to, or engaging in
research and development activities related to, products in such class during
the restricted time period, so long as such Party or its Affiliate does not
engage in the activities set forth in the first two sentences of this paragraph,
as applicable.

take prompt affirmative action to ensure that such activity will cease, and take
additional remedial action to advise its sales personnel concerning the
activities described in this subsection;

          (c) not take any action which constitutes a violation of Applicable

               (i) the commercialization of Product in the Territory; or

               (ii) the then-existing business of GSK, its Affiliates and
licensees with respect to Product in the GSK Territory;

and all governmental approvals as are required for Myogen to fulfill its
obligations hereunder (including filings with the FDA for distributor NDCs). GSK
will cause the NDC number obtained by Myogen to appear on all Product (other
than Product consisting of current inventory of finished goods) sold by GSK to
Myogen as soon as reasonably practicable after Myogen provides the NDC to GSK;

          (f) maintain the availability of the current package inserts with

promote, advertise and distribute the Product in a manner that will not have a
material adverse effect on the Product; and

          (h) support the Patient Assistance Programs with respect to Product in
the Territory as GSK specifically requests and Myogen agrees. For purposes of
this clause (h), the "Patient Assistance Programs" means the indigent programs
maintained by Accredo and TheraCom during the Term, but for which GSK will
determine all eligibility criteria in its sole discretion.

     Section 3.2 Promotional Materials and Promotional Activities.

          (a) Subject to the provisions of Sections 3.2(b) and 3.9 below, after
the Commencement Date, Myogen will be solely responsible, at its sole expense

Product in the Territory (the "Promotional Activities") and for designing,
preparing and distributing all materials and advertisements used in the
promotion, advertising, Detailing and marketing of Product in the Territory

upon the request of GSK, permit GSK personnel to accompany Myogen sales
representatives when Detailing Product to Target Prescribers and to participate

time to time during the Term. Myogen will ensure that all

Promotional Materials and Promotional Activities comply with, and Myogen will be
solely responsible and liable for any failure of such Promotional Materials and
Promotional Activities to comply with the applicable labeling and Product
Registration for Product, Applicable Law, the PhRMA Code and the PhRMA Guiding
Principles, Direct-to-Consumer Advertisements About Prescription Medicines,
notwithstanding any prior review or approval of such Promotional Materials or
Promotional Activities by GSK and notwithstanding that such Promotional
Materials or Promotional Activities may have been previously reviewed, used or
conducted by GSK or may be used or conducted by GSK during the Term in the GSK
Territory. Myogen will be solely responsible for fulfilling regulatory
requirements pertaining to the Promotional Materials and its Promotional
Activities, including, without limitation, sole responsibility for submitting to
FDA all Promotional Materials prepared by or for Myogen at the time of initial
dissemination, by way of a Form FDA-2253, consistent with 21 CFR Part 314.81. To
this effect, GSK will, upon the Commencement Date, or as soon thereafter as is
reasonably practicable, place a letter on file with DDMAC with respect to
Product advising DDMAC that Myogen will be the sole marketer and promoter of
Product in the Territory and requesting that DDMAC address regulatory inquiries
and concerns regarding Myogen's promotional activities solely with Myogen.
Myogen will promptly, but in no event within more than two (2) Business Days
after Myogen's receipt thereof, provide a copy to GSK of any correspondence from
a Governmental Authority with respect to Product, including, but not limited to,
the FDA, reflecting any purported legal or regulatory violations or legal or
regulatory action being considered or taken by such Governmental Authority,
including without limitation, copies of FDA NOV's and Warning Letters. Unless
otherwise required, Myogen will not provide GSK with copies of any Promotional
Materials or notify GSK of any Promotional Activities unless pursuant to a
written request by GSK, in which case such information will be provided by
Myogen to GSK within three (3) Business Days of such request by GSK. Myogen will
absorb and be solely responsible for any and all lost profits, lost revenues,
damages, losses, expenses and costs incurred by Myogen and its Affiliates
arising from the failure of any Promotional Materials used, or Promotional
Activities conducted, by Myogen to comply with the applicable labeling, the
Product Registrations and/or with Applicable Law. Without limiting the rights
GSK may have under the indemnification provisions of this Agreement, but subject
to Section 9.5 hereof, Myogen will promptly reimburse GSK and its Affiliates for
any and all documented damages, losses, expenses and costs suffered or incurred
by GSK and its Affiliates arising from (i) the failure of any Promotional
Materials used, or Promotional Activities conducted by, Myogen to comply with
the applicable labeling, the applicable Product Registrations, Applicable Law,
and/or any comments, guidance or direction given by FDA or DDMAC in the
Pre-Clearance Process pursuant to Section 3.2(b)(ii), or (ii) the failure of
Myogen or its representatives to promote Product in compliance with the
applicable labeling, the applicable Product Registrations and/or with Applicable
Law, including, without limitation, any damages, losses, expenses and costs
reasonably incurred by GSK to so mitigate or limit the effect or impact of (i)
or (ii) above, on GSK and its Affiliates' products or corporate image
(including, but not limited to, the costs of any remedial action GSK may choose
to undertake to communicate with physicians or Customers (including, but not
limited to, so-called "dear doctor letters"). The foregoing obligation of Myogen
will not include any obligation to reimburse GSK or its Affiliates for damages,
losses, expenses or cost suffered or incurred by GSK as a result of acts or
omissions of GSK, GSK' Affiliates or any of their representatives.

          (b) Promotional Review

               (i) If Myogen (or GSK) receives a Warning Letter from the FDA
which relates to marketing, promotion, advertisement, sale or distribution of
Product after the Commencement Date, or Myogen (or GSK) receives two (2) NOV's
from the FDA which relate to marketing, promotion, advertisement, sale or
distribution of Product after the Commencement Date, GSK will have the right to
call, and Myogen will participate/or attend at its own expense, a meeting of
Myogen (which will include senior level marketing and sales management of
Myogen) and GSK, to be held at GSK's offices in Research Triangle Park, N.C. The
purpose of such meeting will be to discuss the Promotional Materials or
Promotional Activities which led to the issuance of the Warning Letter or the
NOV's, as the case may be, and to discuss, if appropriate, appropriate
corrective or remedial measures to Myogen's promotional review process.
Subsequent to any such meeting or in lieu of such meeting (if such meeting is
not held as a result of the mutual agreement of the Parties or as a result of
Myogen's failure or refusal to attend), GSK may, in its sole and absolute
discretion, at any time after the issuance of a Warning Letter or a second NOV
from FDA related to Product after the Commencement Date, decide to invoke the
promotional review procedures set forth in Section 3.2(b)(ii) below by sending
written notice thereof to Myogen (hereinafter, a "Promotional Review Notice").

               (ii) In the event that GSK sends a Promotional Review Notice to
Myogen, Myogen will comply with the procedures set forth in this Section
3.2(b)(ii). Myogen will ensure that all Promotional Materials and Promotional
Activities comply with the applicable labeling and the applicable Product
Registration for Product and with Applicable Law, including, without limitation,
addressing any concerns which were the subject of such FDA letter(s). For a
period of [..**..] after the Promotional Review Notice (the "Pre-Clearance
Period"), Myogen will submit all of the following for review and approval by
DDMAC (the "Pre-Clearance Process") prior to use or dissemination: any and all
Promotional Materials and Promotional Activities (including, without limitation,
detail aids, brochures, reprints and other printed materials shown to or left
with healthcare providers, letters, brochures and other printed materials
intended for consumers, website content, materials for use in promotional
programs, and any print, television, radio, and other media advertising
materials intended for healthcare providers or consumers, speaker slide kits).
Myogen will not use any materials or make any claims in advertising, promoting
or selling Product which have not gone through the Pre-Clearance Process and
received specific and entire written approval by DDMAC; provided, however, that
in the case of materials not accepted for review by DDMAC, Myogen will ensure
that all such materials and the claims and promotional messages therein: (A) are
consistent with the materials and claims that have gone through the
Pre-Clearance Process and received written approval by DDMAC, if any, and (B)
comply with all comments, direction and guidance given by DDMAC during the
Pre-Clearance Period, if any. Myogen will use Commercially Reasonable Efforts to
ensure that all Promotional Activities of all sales representatives promoting
the Product comply with any and all comments, direction or guidance given by
DDMAC during the Pre-Clearance Period. Upon expiration of the Pre-Clearance
Period, Myogen will continue to promote, detail, sell and advertise Product in a
manner consistent with all comments, directions and guidance received from
DDMAC. Myogen will be solely responsible for submitting all Promotional
Materials

prepared by or for it to the FDA by way of a Form 2253 or otherwise. GSK will
have the right to terminate this Agreement on thirty (30) days written notice
if: (1) Myogen fails to fully comply with the requirements of this Section
3.2(b)(ii); or (2) FDA issues a Warning Letter or NOV with respect to Product at
any time during or after the Pre-Clearance Period. Myogen will immediately cease
the promotion of the Product upon receipt of such notice of termination from
GSK.

          (c) GSK will provide Myogen with copies of any advertising,
promotional or training materials in its possession and previously used by GSK
relating to Product in the Territory ("GSK Promotional Materials"), and will
permit Myogen, subject to compliance by Myogen with Applicable Law, to update,
adapt and use such GSK Promotional Materials in the Territory in developing new
Promotional Materials (subject to any copyrights or other rights reserved to
GSK, its Affiliates and to Third Parties in such materials). GSK reserves and
retains title and all rights, including copyright rights, in and to all GSK
Promotional Materials, whether written, visual or electronic works provided by
it to Myogen under this Agreement. Subject to the foregoing, Myogen is granted
the nonexclusive right under this Section to use, copy, modify, and distribute
such GSK Promotional Materials only for the purposes of this Agreement and in
furtherance of the rights granted to Myogen hereunder, for the Term for the
Product to which such works and materials relate. Myogen will ensure that all
copyright notices and this permission notice appear on all copies of the written
materials provided by GSK and all adaptations and derivative works thereof. Any
and all new Promotional Materials developed by Myogen, including that which
adapts or utilizes the GSK Promotional Materials supplied to Myogen by GSK, will
be filed by Myogen with FDA at the time of initial dissemination via Form
FDA-2253.

          (d) Myogen will have strategic responsibility and sole authority and
responsibility, at its sole expense, for independent and non-independent
symposia, speaker training and engagement programs, advisory board meetings and
other consulting arrangements, scientific exhibits and other types of scientific
exchange, and other such events or programs as Myogen, in its sole discretion,
deems to be appropriate with respect to the Product in the Territory; provided,
however, that any and all such events and programs must comply in all respects
with Applicable Law and relevant FDA policies, including without limitation, the
FDA's Guidance on Industry-Supported Educational and Scientific Activities.

          (e) Myogen will provide GSK with copies of any market research
conducted after the Commencement Date regarding Product.

     Section 3.3 Use of Trademarks; Trade Dress. After the Commencement Date and
for the duration of the Term, and subject to the terms and conditions of this
Agreement:

          (a) GSK hereby grants to Myogen an exclusive (except as otherwise
provided in this Agreement), royalty free license to use the Trademarks to
promote, market, sell and distribute the Product in the Territory during the
Term. Myogen will not identify Product by any designation other than the
Trademarks, except that Myogen may identify itself as distributor of Product.
With respect to Product which bears Myogen's NDC codes as provided herein,
Myogen will be identified as the distributor of such Product on the Product's
label as the same

not specify how the distributor will be indicated on a Product's label, then as
determined (including without limitation as to size and placement) jointly by
GSK and Myogen. The use of the Trademarks by Myogen will be expressly subject to
subparagraph (c) below.

          (b) Myogen will use the Trademarks solely with respect to Product
purchased from GSK or its designee as provided in this Agreement, only in
accordance with the standards of quality established or approved by GSK or its
designee, and only in the Territory. Myogen will permit duly authorized
representatives of GSK to inspect, on the premises of Myogen or its
subcontractors and agents, at reasonable times during normal business hours and
upon not less than ten (10) Business Days prior written notice, inventory of
Product, Myogen's quality control records, and Myogen's facilities used in or
relating to the sale of Product to ensure compliance with quality control
standards and with applicable terms of this Agreement pertaining to the use of
the Trademarks.

          (c) Whenever Myogen uses the Trademarks in any Promotional Materials
or in any other manner in connection with Product, Myogen will clearly indicate
that the Trademarks are owned by the GlaxoSmithKline group of companies. When
using the Trademarks under this Agreement, Myogen will comply with all
Applicable Law pertaining to the Trademarks in force at any time in the
Territory. During the Term, Myogen will provide GSK with copies of Promotional
Materials on a periodic basis, as requested by GSK, for review of the use of the
Trademarks by Myogen. Myogen will promptly take any and all actions directed by
GSK with respect to Myogen's use of the Trademarks that are reasonably designed
to ensure compliance with the provisions of this Section 3.3.

          (d) Myogen acknowledges and agrees that GSK and/or its Affiliates, is,
and at all times will remain the owner of the Trademarks. Myogen will not at any
time do, cause to be done, or permit any of its employees, agents, contractors
and subcontractors to commit any act inconsistent with, contesting or in any way
impairing, or tending to impair, such ownership. Myogen agrees that all use of
the Trademarks by Myogen will inure to the benefit of and be on behalf of GSK or
its Affiliates. Myogen acknowledges that nothing in this Agreement will give
Myogen any right, title or interest in the Trademarks other than the right to
use the Trademarks within the Territory in accordance with this Agreement.
Myogen agrees that it will not challenge GSK's or its Affiliates' title to, or
ownership of, the Trademarks, or attack or contest the validity of the
Trademarks. All goodwill accruing to the Trademarks as a result of the use of
the Trademarks in the performance of this Agreement will belong solely to GSK or
its Affiliates. In the event that Myogen acquires any rights in the Trademarks
in connection with Myogen's activities pursuant to this Agreement, Myogen will
assign, and hereby does assign, to GSK or its Affiliates all such rights,
including any related goodwill.

          (e) Myogen is limited to using the Trademarks in connection with the
Internet as follows:

                (i) the use must be in compliance with local rules regarding
advertising of pharmaceuticals on the Internet;

               (ii) the use of any Trademarks as a domain name is limited to the
relevant country code domain within the Territory. No license is granted to use
the ".com generic code domain" or any other such top-level domain. All domain
names containing the Trademark will be registered and maintained by and in the
name of GSK or its designee;

                (iii) the use of any Trademarks as a domain name is limited to
use on websites with universal resource locaters using the relevant country code
domain within the Territory and aimed at audiences in those countries in the
Territory;

                (iv) appropriate disclaimers must be included in any website to
the effect that it is intended for residents in that country within the
Territory only; and

               (v) in using any of the Trademarks as a domain name or on the
Internet, Myogen will not have and will not represent in any way that it has any
title or right to the ownership or registration or their use, except as provided
in this Agreement. Myogen will at all times indicate that each of the Trademarks
is a trademark of the GlaxoSmithKline group and is used under license.

     Section 3.4 Trademark Infringement by Third Parties. If either Party
becomes aware that a Third Party is infringing any Trademark used in connection
with Product in the Territory, such Party will give written notice to the other
Party describing in detail the nature of such infringement. GSK and its
Affiliates will have the first right, but not the obligation, to enforce any
such Trademarks against such Third Party infringer, in their reasonable
discretion, and to settle or compromise any such possible infringement by taking
such action as GSK or its Affiliates may determine in their sole and absolute
discretion; provided, however that no settlement or consent judgment or other
voluntary final disposition of any suit or action pursuant to this Section 3.4
may be entered into without the consent of Myogen if such settlement would
subject Myogen to an injunction or if such settlement or judgment would
materially diminish or limit or otherwise materially and adversely affect the
rights, activities or financial interests of Myogen. If GSK does not commence a
particular infringement action within ninety (90) calendar days of receipt of
the notice of infringement, then Myogen, after notifying GSK in writing, will be
entitled but will have no obligation to bring such infringement action at its
own expense. In any event, GSK and Myogen will provide the other Party with all
reasonable assistance (including, without limitation, making documents and
records available for review and copying, and making persons within its control
available for pertinent testimony), at the other Party's expense, in such
enforcement.

     Section 3.5 Rebates and Chargebacks.

          (a) GSK's Obligations. GSK will be responsible for all governmental

thereof as determined by Myogen; provided, however, that the Net Effective Price
Increase in any Contract Year for any SKU of the Product will not exceed

     Section 3.8 Sales Force.

          (a) All members of Myogen's sales force (including management and
sales representatives) will complete a Product-related training program
conducted by Myogen at its cost and expense. All members of Myogen's sales force

previously used in training sales representatives in the Territory on the
Product. Myogen will have the sole responsibility for any such materials and for

contents of any training provided by Myogen that relates to the Product will be
developed and coordinated by Myogen, and Myogen will be solely responsible for
training its sales force (including management and sales representatives) with
regard to Applicable Law and directing such sales force and sales force
personnel to be compliant with Applicable Law, regardless of whether Myogen
utilized GSK provided materials for training.

           (b) As of the Commencement Date and continuing during the Term, Myogen

during the Term, Myogen will maintain policies and procedures in effect that
require, and that it will otherwise require, all employees and contractors to
immediately disclose to Myogen any debarment, exclusion, suspension or other
event that may make such employee or contractor an Ineligible Person. If Myogen
has actual notice that one of its employees or contractors providing services
under this Agreement has become or is likely to become an Ineligible Person,
Myogen will remove such Person from any responsibility associated with this
Agreement and the Product. If Myogen has actual notice that one of its employees
or contractors is charged with a criminal offense related to any Federal health
care program, or is proposed for exclusion, Myogen will take all appropriate
action to ensure that the responsibilities of such Person have not and will not
in the future adversely affect this Agreement and the Product.

     Section 3.9 Diligence Requirements.

          (a) Myogen will employ sales force representatives and other marketing

such Details will be provided during at least [..**..] Business Days during each
Contract Year at an average rate of [..**..] Details during each such Business
Day, provided, however, that the Parties agree to pro-rate the Details required

following number of Details during each Contract Year:

                    (A) First Year - [..**..] Details;

                    (B) Second Year - [..**..] Details; and

Prescribers will be subject to the approval of GSK, not to be unreasonably
withheld. At either Party's request, the Parties shall consult on a Calendar
Quarterly basis regarding the list of Target Prescribers. If Myogen fails to
provide the minimum number of Details specified for a given Contract Year, but
provides at least [..**..] of such number, Myogen shall not be in breach of such
obligation, provided that it pays to GSK an amount equal to [..**..] in the
number of required Details multiplied by [..**..], such payment to be made
within thirty (30) calendar days of the end of the applicable Contract Year.

                (ii) In addition to Sales Representative FTEs, Myogen
acknowledges and agrees that within thirty (30) calendar days after the
Commencement Date and for the duration of the Term, it will maintain the
following marketing personnel to support Myogen's obligations with respect to
Product in the Territory:

                    (A) [..**..];

                    (B) [..**..];

                    (C) [..**..];

                    (D) [..**..]; and

                    (E) [..**..].

Myogen represents and warrants that no individual will hold more than one
position set forth above.

               (iii) Myogen acknowledges and agrees that during the First (1st)
Contract Year, the Incentive Compensation for Product available to be earned by
each sales representative and sales marketing personnel involved in the
promotion of Product in the Territory will be [..**..] the Incentive
Compensation (defined below) available to be earned for any other product for
which such sales representative or sales marketing personnel is being
compensated. During the second (2nd) Contract Year and each Contract Year
thereafter during the Term, the Incentive Compensation for Product available to
be earned by each sales representative and sales marketing personnel involved in
the promotion of Product in the Territory will be [..**..] the Incentive
Compensation available to be earned by such sales representatives and sales
marketing personnel for all products promoted by Myogen to Target Prescribers
multiplied by a fraction, the numerator of which is equal to the number of Sales
Representative FTEs required to be provided during such Contract Year under
Section 3.9(b) and the denominator of which is equal to the number of Myogen
sales representatives actively Detailing physicians who are treaters of
pulmonary hypertension during such Contract Year. For the purposes of this
Section 3.9(c)(iii), "Incentive Compensation" means incentive compensation for a
product available to be earned by a sales representative or sales marketing
personnel of Myogen based on [..**..] quota attainment pursuant to the terms of
the then current incentive compensation plan for such sales representative or
sales marketing personnel. During the Term,

Myogen acknowledges and agrees that [..**..] quota attainment for Product, if
based upon Gross Sales in any Contract Year, will not be based on a Gross Sales
amount that is greater than the Baseline Gross Sales for such Contract Year.

               (iv) Myogen will be solely responsible for the costs and expenses
of establishing and maintaining its sales force and marketing functions for the
Product, and for conducting its other activities under this Agreement, and
subject to the foregoing, will have the sole authority to control its sales
force and direct the activities of its sales force.

          (d) Myogen acknowledges and agrees that it will spend not less than
the following for advertising and promotion activities relating to Product under
this Agreement (including Myogen's reasonable, documented internal costs for
personnel providing services in connection with such activities that would
typically otherwise be provided by a Third Party vendor (e.g., an advertising
agency)); provided, however, that such amounts will not include those expenses
relating to the compensation of sales force and marketing personnel as set forth
in Section 3.9:

               (i) If no Generic Equivalent is sold in the Territory prior to
the start of the [..**..] Calendar Quarter of [..**..], then:

                    (A) for the First Year - [..**..] of Gross Sales;

                    (B) for the Second Year - [..**..] of Gross Sales; and

                    (C) for the Third Year - [..**..] of Gross Sales;

               (ii) If a Generic Equivalent is not first sold in the Territory
until after the end of the [..**..] Calendar Quarter of [..**..] but prior to
the start of the [..**..] Calendar Quarter of [..**..], then:

                    (A) for the First Year - [..**..] of Gross Sales;

                    (B) for the Second Year - [..**..] of Gross Sales; and

                    (C) for the Third Year - [..**..] of Gross Sales; and

               (iii) If a Generic Equivalent is sold in the Territory prior to
the end of the [..**..] Calendar Quarter of [..**..], then:

                    (A) for the First Year - [..**..] of Gross Sales;

                    (B) for the Second Year - [..**..] of Gross Sales; and

                    (C) for the Third Year - [..**..] of Gross Sales.

     For avoidance of doubt, Myogen shall not be obligated to incur expenses for
advertising and promotion activities relating to Product in excess of the
amounts stated above, unless Myogen elects in its sole discretion to do so. If
Myogen fails to spend the applicable, specified amounts for advertising and
promotion activities in a given Contract Year, but spends at least [..**..] of
such amounts, Myogen shall not be in breach of such obligation, provided that it
pays to GSK an amount equal to the spending shortfall, such payment to be made
within thirty (30) calendar days of the end of the applicable Contract Year.

as to any developments that may have a material adverse effect on a Product
Registration. Myogen will cooperate with GSK with respect to obtaining and
maintaining the Product Registrations, and will execute, acknowledge and deliver
such further instruments at GSK's request and expense, and use Commercially
Reasonable Efforts to do all such other acts, as promptly as possible, which may
be necessary or appropriate to obtain and maintain the Product Registrations in

obligations hereunder to fulfill such Product Registration maintenance
requirements (including, but not limited to, providing sales distribution
information concerning the Product). GSK will have the final decision-making
authority in every case on whether and how to supplement, amend or otherwise
alter the Product Registrations and any other issues in connection with such
Product Registrations (including, but not limited to, decisions, subject to
Section 6.8, to recall the Product) and on whether and how to communicate with
the FDA and other applicable governmental agencies or authorities in connection
with such Product Registrations.

          (b) GSK and Myogen each will make its respective facilities available
at reasonable times during business hours for inspection by representatives of
Governmental Authorities relating to the manufacture, sale, marketing,
promotion, distribution, or use of Product in the Territory. GSK and Myogen each
will notify the other within twenty-four (24) hours (or, if such twenty-four
(24) hour period ends on a day that is not a Business Day, then prior to Noon on
the next following Business Day) of receipt, and provide a copy thereof, of any
notice of any FDA or other Governmental Authority inspection, investigation or
other inquiry, or other material governmental notice or communication, relating
to the manufacture, sale, marketing, promotion, distribution, or use of Product
in the Territory. Myogen and GSK will cooperate with each other during any such
inspection, investigation or other inquiry. Myogen and GSK will discuss any
response to observations or notifications received in connection with any such
inspection, investigation or other inquiry and each will give the other an
opportunity to comment upon any proposed response before it is made; provided,
however, that (i) GSK will not be required to discuss with Myogen any issues
specific to the manufacture of Product, unless it impacts Myogen's ability to
distribute the Product under this Agreement, or to obtain the consent or
agreement of Myogen with respect to issues related thereto, and (ii) Myogen will
be solely responsible for responding to inquiries and actions from Governmental
Authorities relating to Promotional Activities and Promotional Materials as
contemplated by Section 3.2. In the event of disagreement concerning the form or
content of such response, however, GSK will be responsible for deciding the
appropriate form and content of any response with respect to any of its
governmental agency cited activities and Myogen will be responsible for deciding
the appropriate form and content of any response with respect to any of its
governmental agency cited activities. Myogen and GSK will provide each other
with copies of all correspondence received by it from, or filed by it with, any
Governmental Authority to the extent pertaining to Product in the Territory or
its labeling, packaging, distribution, promotion, advertisement, marketing or
sale in the Territory; provided, however, that Myogen will not provide copies of
Promotional Materials to GSK unless requested by GSK in writing as provided in
Section 3.2(a). In addition, GSK will provide Myogen copies of all material
correspondence received by GSK from, or filed by GSK with, any Governmental
Authority to the extent such correspondence or filing could reasonably, in GSK's
opinion, have an affect on Myogen's ability to perform its obligations under
this Agreement. Nothing in this Section 4.2(b) will limit or condition the
rights of either Party under Section 6.12.

          (c) GSK will have sole responsibility and authority for, and control
of, all package inserts and package labeling (and any changes or supplements

the responsibility at its expense for securing any approvals required by FDA to
any such changes or supplements thereto. Myogen will not at any time do, and
neither will Myogen permit its agents or representatives to do, any act in
violation of the Product Registration for Product in the Territory. In the event
that any filings are required to be made with or approvals required to be
obtained from applicable regulatory authorities in order to change or supplement
the package inserts and labeling, GSK will have the sole responsibility for and
authority to effect such filings and the sole right and discretion on how to
effect such changes at GSK's expense. GSK will promptly, but in no event less
than five (5) Business Days, advise Myogen in writing of any changes or
supplements to the package inserts and package labeling for Product. The Parties
acknowledge and agree that Product sold immediately after the Commencement Date
will be sold under a GSK label; however, as soon as reasonably practicable
following the Commencement Date, all Product will be identified as product
manufactured by GSK and Myogen will be identified as the distributor thereof,
including the Myogen NDC and logo. Myogen will, within thirty (30) calendar days
after the Commencement Date, provide GSK with all information for Myogen's logo
and NDCs.

     Section 4.3 Prosecution and Maintenance of Trademarks and Patents.

          (a) GSK will register and maintain, or cause to be registered and
maintained, at its cost and expense, the Trademarks in the Territory during the
Term. The rights of the Parties with respect to Trademark infringement are set
forth in Section 3.4 of this Agreement.

          (b) Notwithstanding any other provision of this Agreement to the
contrary, GSK and its Affiliates will have the right but not the obligation to
prosecute, maintain or abandon any patent rights and know-how owned or
controlled by GSK covering the Product. GSK will not abandon any patent right or
know-how owned or controlled by GSK with respect to the Product in the Territory
without giving thirty (30) days prior written notice to Myogen. Should GSK elect
to abandon any patent in the Territory contained in the Intellectual Property,
GSK will (i) provide Myogen with written notice as soon as reasonably possible
after making such election but in any event no later than sixty (60) calendar
days after making such election but in any event before a possible loss of
rights, and Myogen will have the right to prosecute and maintain such patent in
its sole discretion, at its sole expense and in GSK's name, Myogen's name or the
name of both GSK and Myogen, as determined by GSK in its sole discretion.

          (c) GSK will have the sole right, but not the obligation, at its sole
discretion and expense, to maintain and enforce any contract entered into by GSK
covering the supply of any compounds, intermediates, biomaterials, packaging
components, containers and other materials used in the manufacture of Product.

          (d) If either Party becomes aware of actual or threatened infringement
of a patent included within the Intellectual Property anywhere in the Territory
by a Third Party, including any action or proceeding filed in connection with an
ANDA filed by a Third Party related to the Intellectual Property, that Party
will promptly notify the other Party in writing. GSK will have the first right,
but not the obligation, to bring, at its own expense, an infringement action
against any Third Party. If GSK does not commence a particular infringement
action within ninety (90) calendar days of receipt of the notice of
infringement, then Myogen, after

notifying GSK in writing, will be entitled but will have no obligation to bring
such infringement action at its own expense. The Party conducting such action
will have full control over and will use Commercially Reasonable Efforts to
conduct such action, including settlement thereof subject to Section 4.3(f). In
any event, GSK and Myogen will provide reasonable assistance to one another and
will reasonably cooperate in any such litigation at the other's request [..**..]
to the requesting Party.

          (e) GSK and Myogen will recover its actual and reasonable
out-of-pocket expenses associated with any litigation or settlement thereof from
any recovery made by either Party. In the event GSK was the Party to commence an
infringement action pursuant to Section 4.3(d), any excess amount attributable
to compensatory and punitive damages for infringement of any patent included
within the Intellectual Property, such amount will be shared between Myogen and
GSK, provided that Myogen's share of any excess amount attributable to
compensatory and punitive damages for sales of the product that was the subject
of the litigation will be limited to the amount of, or proportionate to,
compensation that Myogen would have been entitled to receive had those been
sales of Product in the Territory made by Myogen. In the event Myogen was the
Party to commence an infringement action pursuant to Section 4.3(d), then any
excess amount attributable to infringement of any patents included within the
Intellectual Property will be retained solely by Myogen.

          (f) The Parties will keep one another informed of the status of its
activities regarding any litigation or settlement thereof concerning the
Intellectual Property; provided, however that no settlement or consent judgment
or other voluntary final disposition of any suit or action pursuant to Section
4.3(d) may be entered into without the consent of the other Party if such
settlement would subject such Party to an injunction or if such settlement or
judgment would materially diminish or limit or otherwise materially and
adversely affect the rights, activities or financial interests of such Party.

          (g) Each Party shall retain the right to be represented by counsel of
its own selection and its own expense in any suit or other action instituted by
the other Party pursuant to Section 4.3(d).

     Section 4.4 Patient Assistance Programs. During the Term, GSK will use
Commercially Reasonable Efforts to continue to support the Patient Assistance
Programs by (a) overseeing Accredo's and TheraCom's enrollment of eligible
Patient Assistance Program recipients, (b) providing sufficient inventories of
Product to Accredo and TheraCom for distribution under the Patient Assistance
Program, (c) providing Myogen with monthly reports, which reports will set forth
the number of patients receiving Product under the Patient Assistance Program
and the amount of Product shipped to Customers pursuant to the Patient
Assistance Program, (d) issuing a credit to Myogen for any amounts paid by
Myogen to GSK for Product distributed under the Patient Assistance Program, and
(e) providing such additional information as reasonably requested by Myogen
regarding the Patient Assistance Program.

     Section 4.5 Product Improvements. GSK will have no obligation, express or
implied, to develop new formulations, indications, dosages, presentations, forms
of administration, or

preparations for Product. However, if GSK does develop a new formulation,
dosage, presentation, form of administration or preparation for Product (a
"Product Improvement") during the Term, such Product Improvement will be deemed
to be included within the definition of Product; provided, that the Parties
agree in writing upon any terms in addition to those set forth in this Agreement
(including, without limitation, promotional diligence and supply price) pursuant
to which Myogen will promote and distribute, and GSK will supply, such Product
Improvement in the Territory. If the Parties, despite good faith negotiations,
cannot reach agreement on such additional terms, the Product Improvement will
not be deemed to be included within the definition of Product and GSK will be
free to market, promote, advertise, sell and distribute such Product Improvement
in the Territory during the Term; provided, however, that GSK will not enter
into any agreement with a Third Party with respect to such Product Improvement
in the Territory that includes terms that are less favorable to GSK than those
last offered by Myogen during the Parties negotiations.
