to time) as provided herein (each such approved subdistributor, an "Approved
Subdistributor") and (b) to delegate to such Approved Subdistributor the whole
or any part of its obligations; provided that (i) Endo shall remain primarily
liable for the Approved Subdistributor's compliance with this Agreement, (ii)
prior to or concurrently with its appointment, each Approved Subdistributor

hereof, (iii) each Approved Subdistributor Agreement shall name Noven as a third
party beneficiary, and (iv) no Approved Subdistributor Agreement shall permit
such Approved Subdistributor to appoint or assign such agreement, or delegate
any obligations, to any other subdistributor. Endo shall be solely responsible
for the fees of, and any other payments to, each Approved Subdistributor. Upon
Noven's request, Endo shall make available to Noven a redacted copy of each
Approved Subdistributor Agreement evidencing such agreements conformance with
the requirements of this Section 2.04. The foregoing notwithstanding, nothing
herein shall prevent or prohibit Endo from using subcontractors to perform

provided, however, that (i) Endo shall retain strategic control over the
marketing and sale of Licensed product, (ii) Endo shall remain fully liable and
responsible to Noven for all actions and/or inactions of its subcontractors
under this Agreement as though such actions and/or inactions were made by Endo

other payments to, each subcontractor.

reasonable efforts to Launch the Licensed Product promptly after Regulatory
Approval of the Product ANDA and, at its own expense, to actively and diligently
promote, market and sell the Licensed Product in the Territory during the term

it has received all launch supplies of Licensed Product properly ordered from
Noven pursuant to the Supply Agreement; provided that any delays or non-delivery
of Licensed Product under the Supply Agreement are not a result of a breach of
the Supply Agreement by Endo.

         (c) Endo's obligation to Launch and to sell Licensed Product shall be
suspended ***

         (d) Endo's obligation to Launch and sell Licensed Product shall be
suspended for such time as it is prevented from selling Licensed Product by a
court order in the relevant territory that Licensed Product infringes a valid
claim of a patent of a Third Party or Endo is prohibited from marketing the
Licensed Product by any judgment, order, injunction, decree or award of any
court, administrative agency, or arbitrator or government body.

         (e) Except as otherwise set forth in this Article IV and Section 14.14,
if Endo fails to commence to market any Licensed Product in accordance with the
requirements of this Article IV, and such failure continues for a period of
fifteen (15) business days after written notice from Noven to Endo, then this
Agreement shall immediately terminate upon notice to Endo by Noven. Thereafter,
Noven shall be free to use and sell Licensed Product in the territory as it may
see fit. If Noven determines to terminate this Agreement with respect to the
Licensed Product, Endo shall promptly take such actions as Noven may reasonably
request, in order to transfer to Noven or its designee, for no additional
consideration, all of Endo's right, title, and interest in and to any Regulatory
Approvals relating to the Licensed Product in such country, and all information
relating to any Regulatory Approvals not previously supplied to Noven.

         Section 4.03 Marketing Plan. No later than ninety (90) days before the
first commercial sale of Licensed Product, Endo shall provide Noven with a
written marketing plan setting forth a detailed description of Endo's strategies
and business plan with respect to the marketing, distribution, and sale of the
Licensed Product in the Territory (the "Marketing Plan"). Thereafter, Endo
Agrees to keep Noven apprised of its strategies and business plan with respect
to the marketing, distribution, and sale of the Licensed Product in the
Territory, and to provide to

Noven such other marketing related information as Noven shall reasonably
request. Endo shall also provide Noven with an updated copy of the Marketing
Plan prior to the beginning of each subsequent calendar year during the term of
this Agreement. At Noven's request, designated employees of each of the parties
shall confer not more than once every calendar quarter either in person at a
location to be mutually agreed upon, or by teleconference, to discuss the
Marketing Plan, competitive market conditions, strategic changes in the
marketplace and Endo's respective actions and planned responses thereto.

         Section 4.04 Limitations on Endo's Marketing of the Licensed Product.
Endo shall be permitted to market and sell the Product as it would normally
market and sell products of comparable market potential in the ordinary course
of Endo's business. ***

         Section 5.01. Canada. Noven hereby authorizes Endo to appoint an

mutually agreed to between the Parties and set forth in Exhibit D and Noven will
use reasonable efforts to provide the deliverables described therein to Endo by

candidate that has failed the feasibility studies.

         Section 8.02 Additional Commitments Regarding Additional Products. As
Noven performs its technical feasibility work, the product candidates will be
evaluated by the parties against Endo's clinical development criteria. Endo will
determine whether an Additional Product will move into pilot studies within ***

that an Additional Product will move into pilot studies, Endo will conduct pilot
studies on the successful candidates ***. Within *** days of the completion of
human pharmacokinetic studies on each Additional Product that has been nominated
for pilot studies, Endo will determine whether such Additional Product will move
into full clinical development. If Endo determines that an Additional Product is
to move into final clinical work then the parties will negotiate a
Commercialization Agreement pursuant to Section 8.03 below. Endo will move each
nominated Additional Product for which a Commercialization Agreement is entered
into between the Parties into full clinical development. If Endo at any time
makes a final decision not to advance an Additional Product into pilot studies
or nominate it for full clinical development, Noven shall be thereafter free to
develop, license and/or commercialize such compound for its own benefit. Noven
agrees to work with Endo in good faith to provide additional information to aid
Endo in making its determination of whether to move each Additional Product into
pilot studies and thereafter into full clinical development . Endo agrees to
work with Noven in good faith in determining whether to move each Additional
Product into pilot studies and thereafter into full clinical development.

         Section 8.03. Commercialization Agreement. Once a product is nominated
for full clinical development, the parties will have *** days to establish
business terms for commercialization and to establish a clinical plan and budget

parties cannot agree to terms in the *** period, then ***.

such Proceeding, at its sole expense, including the settlement thereof at the
sole option of the Indemnifying Party or its insurers; provided, however, that

shall try to settle their differences amicably between themselves. Any party may
initiate such informal dispute resolution by sending written notice of the
dispute to the other parties, and within ten (10) days after such notice, the

arbitration shall pay, and to the extent applicable reimburse the prevailing
party for, the costs and expenses of the arbitrator, including costs and
expenses payable to the American Arbitration Association mid to the arbitrator;
and provided further, that in the event each party prevails as to certain claims
in connection with any such arbitration, the fees of the arbitrator shall be
paid and/or reimbursed in accordance with the decision of the arbitrator. Each
party shall bear its own costs incurred in connection with attorneys' fees and
related expenses. Notwithstanding the foregoing provisions of this Section 8.02,
