provided, however, that if there is, during the Initial Period, an increase in
the price of the tangible raw materials included in the TIMERx that is
significantly in excess of the increase in the Producers' Price Index for the
comparable period, the TIMERx Cost of Materials shall, at PENWEST's election, be

********************************************************************************
********************************************************************************
********************************************************************************
*****************. MYLAN may present potential Authorized Distributors to
PENWEST for PENWEST's consideration at any time during the term of this
Agreement. In the event that either party presents a potential Authorized
Distributor to the other party, said other party shall respond within thirty
days by accepting or rejecting the proposed Authorized Distributor. A failure to
respond shall be deemed an acceptance by said other party. An acceptance or
rejection of an Authorized Distributor shall mean that the parties agree or do
not agree to proceed with discussions and negotiations with said Authorized
Distributor. It is specifically recognized by both parties that the discussions
and negotiations may not lead to an Authorized Distributor Agreement and neither
party makes any warranty as to the success of the negotiations leading to an
Authorized Distributor Agreement.

                  2.2 The terms of the Authorized Distributor Agreement(s), if
any, shall be determined by PENWEST and the Authorized Distributor, provided
that none of such terms shall conflict with this Agreement nor preclude
PENWEST's compliance with this Agreement, specifically including, but not
limited to, protecting the confidentiality of the MYLAN Manufacturing
Technology. MYLAN shall be entitled to review the terms and conditions of any
Authorized Distributor Agreement. It is understood that, while PENWEST intends
to attempt to obtain and to maintain one or more Authorized Distributors, it has
not committed that it will be able to do so and will have no liability to MYLAN
for any failure to do so. Except as set forth in Section 2.3 and Section 5.7,
MYLAN shall have no responsibility for assisting PENWEST or the Authorized
Distributor in obtaining registrations or approval to market the Product in the
Territory.

                  2.3 Upon request for specific information by PENWEST and/or an
Authorized Distributor, MYLAN shall, at no significant expense to MYLAN, provide
to the Authorized Distributor, in a reasonably timely manner, such information
in its possession necessary to allow the Authorized Distributor to obtain and
maintain regulatory approval to market the Products in the Territory. Such
disclosures shall include, after receipt of reasonable prior notice to MYLAN,
MYLAN's giving duly accredited representatives of PENWEST and/or the Authorized
Distributor(s) access at all reasonable times during regular business hours to
inspect and audit any relevant records of MYLAN's plant in which the Product or
any raw materials therefor are produced, packaged or stored, all to the extent
required to allow the Authorized Distributor to obtain and maintain regulatory
approval to market the

Products in the Territory. Any such disclosure shall be subject to the
Confidentiality provisions set forth herein. PENWEST shall confirm the date of
submission of all applications for required registrations and approvals from any
applicable regulatory authority in the Territory and then quarterly inform MYLAN
in writing about the status of said application in the Territory, as such
information is available to PENWEST from the Authorized Distributor. PENWEST
shall also obtain the agreement of the Authorized Distributor(s) ************ 
to obtain the necessary registrations in the Territory and to market and sell 
the Product in the Territory.

III.              TERM

                  The Term of this Agreement shall begin on the date first
hereinabove entered and shall continue for a period of ten (10) years ("Initial
Term") or, if later, until the expiration of the term of any Authorized
Distributor Agreement then in force, provided that MYLAN was given notice of
such term of the Authorized Distributor Agreement at least ******************* 
prior to its execution and MYLAN did not object thereto in writing within such
period; provided, however, that MYLAN has already received notice of the
proposed term of an agreement with Sanofi, as set forth in Exhibit 2 hereto,
and need not be given further notice thereof as to that agreement. The Term of
this Agreement shall automatically renew for additional terms of one (1) year
("Additional Terms") unless, not later than six (6) months prior to the end of
the Initial Term or any Additional Term, one party provides written notice to
the other party that the term of this Agreement will not be renewed past the
end of such then-current term. The term of this Agreement will, at PENWEST's
option, remain in effect as specified herein notwithstanding the earlier
termination of the Nifedipine XL Agreement, but only if such termination is as
a result of: (i) the expiration of the Term of the Nifedipine XL Agreement or
(ii) the breach of the Nifedipine XL Agreement by MYLAN. In the event the Term
of this Agreement exists beyond the term of the Nifedipine XL Agreement, those
terms and provisions contained in the Nifedipine XL Agreement, which are
necessary for MYLAN to perform under this Agreement shall survive as if fully
set forth herein.

IV.               INDEMNIFICATION AND INSURANCE

                  4.1 MYLAN agrees to indemnify, defend and hold PENWEST
harmless from and against any and all liabilities, damages, costs or expenses,
including reasonable attorney's fees, ("Losses") resulting from or arising out
of MYLAN's manufacturing, storage, handling, distribution, and/or delivery of

Product at the FOB delivery point, the execution of MYLAN of this Agreement, the
performance or breach by MYLAN of its representations, warranties or obligations
under this Agreement, the negligence or willful misconduct of MYLAN, its
employees or its agents (collectively "MYLAN Activities"), including without
limitation any matters or MYLAN Activities that would be the responsibility of
MYLAN as provided under the Nifedipine XL Agreement (that is, as if the
Nifedipine XL Agreement contemplated the manufacture and sale of the Product for
distribution in the Territory pursuant to this Agreement), except: (1) to the
extent such Losses result from PENWEST Activities (as defined in Section 4.2);
and (2) MYLAN's indemnity, defense and hold harmless responsibilities as to
claims of patent infringement in the Territory shall apply only to infringements
of which MYLAN knew or (without undertaking any special investigation) had
reason to know prior to the delivery at the FOB delivery point to PENWEST of the
units of the Product at issue, and of which MYLAN failed to inform PENWEST in
writing at or prior to the earlier of such delivery or thirty (30) days
following MYLAN's first obtaining such knowledge or reason to know.

                  4.2 PENWEST agrees to indemnify, defend and hold MYLAN
harmless from and against any Losses resulting from or arising out of PENWEST's
or any Authorized Distributor's re-packaging, labeling, testing, storage,
handling, distribution, delivery, marketing and/or sale of the Product
(including without limitation the Consignment Inventory), the execution by
PENWEST of this Agreement, the breach by PENWEST of its representations,
warranties or obligations under this Agreement, the negligence or willful
misconduct of PENWEST, its employees or its agents (collectively "PENWEST
Activities"), including without limitation any matters or PENWEST Activities
that would be the responsibility of PENWEST as provided under the Nifedipine XL
Agreement, except to the extent such Losses result from MYLAN Activities (as
defined in Section 4.1).

                  4.3 A party seeking indemnification ("Indemnified Party"),
shall notify, in writing, the other party ("Indemnifying Party") within
****************** of the assertion of any claim or discovery of any fact upon
which the Indemnified Party intends to base a claim for indemnification. An
Indemnified Party's failure to so notify the Indemnifying Party shall not,
however, relieve such Indemnifying Party from any liability under this Agreement
to the Indemnified Party with respect to such claim except to the extent that
such Indemnifying Party is actually denied, during the period of delay in
notice, the opportunity to remedy or otherwise mitigate the event or
activity(ies) giving rise to the claim for indemnification and thereby suffers
or otherwise incurs additional liquidated or other readily quantifiable damages

result of such failure. The Indemnifying Party, while reserving the right to
contest its obligations to indemnify hereunder, shall be responsible for the
defense of any claim, demand, lawsuit, or other proceeding in connection with
which the Indemnified Party claims indemnification hereunder. The Indemnified
Party shall have the right, at its own expense, to participate jointly with the
Indemnifying Party in the defense of any such claim, demand, lawsuit or other
proceeding, but with respect to any issue involved in such claim, demand,
lawsuit or other proceeding with respect to which the Indemnifying Party has
acknowledged its obligation to indemnify the Indemnified Party hereunder, the
Indemnifying Party shall have the right to select counsel, settle, try or
otherwise dispose of or handle such claim, demand, lawsuit or other proceeding
on such terms as the Indemnifying Party shall deem appropriate, subject to any
reasonable objection of the Indemnified Party. If the defendants in any such
action include both MYLAN and PENWEST, and either party concludes that there may
be legal defenses available to it which are different from, additional to, or
inconsistent with, those available to the other, that party shall have the right
to select separate counsel to participate in the defense of such action on its
behalf, and such party shall thereafter bear the cost and expense of such
separate defense.

                  4.4 Each party shall, at its own cost and expense, obtain and
maintain from a qualified insurance company comprehensive general liability and
products liability insurance coverage during the term of this Agreement. Such
insurance shall be in an amount no less than ********************************* 
combined single limit for each occurrence for bodily injury and/or property
damage. Each party agrees to provide the other party with a certificate of
insurance evidencing such insurance within thirty (30) days after the execution
of this Agreement and again thereafter from time to time as reasonably
requested by such other party.

V.                PRODUCT PRICING

                  5.1 The price of the Product to be supplied to PENWEST under

within ********* following the receipt by PENWEST of such Other Compensation.
Provided, however, if the combined first, second, and third components of the

of the Other Compensation shall then be paid to MYLAN under this Section. If
additional biostudies should be required for Product approval in the Territory,
MYLAN and PENWEST will ********* ********* the cost of additional biostudies.
PENWEST shall **************** for said required biostudies and shall be
reimbursed the amount from Other Compensation until such amount has been
recovered by PENWEST up to a maximum of **********. The necessity of such
studies shall be agreed to by both MYLAN and PENWEST.

VI.               SUPPLY OF PRODUCT

                  6.1 As provided herein, PENWEST shall purchase in whole lot
quantities, and MYLAN will supply PENWEST with, sufficient quantities of Product
to meet all of the requirements therefor of each Authorized Distributor during

than whole lot quantities, up to a ****************** as reasonably requested
for use in the testing and certification of the Product and its manufacture.
MYLAN and PENWEST will share equally the costs of such testing and certification
quantities by adjustments to the amounts payable from Other Compensation. To the
extent permitted under applicable law, PENWEST shall cause the Authorized
Distributor(s) to agree that they shall purchase all of their requirements for
the Product from PENWEST during such period, subject to such commercially
reasonable contingent agreements (the "Contingent License") as PENWEST may make
to permit one or more Authorized Distributors to manufacture the Product on its
own (or to obtain it from an alternate source) in the event that MYLAN is not
able, or for any reason fails, for any continuous period in excess of *********,
or has been so unable, or has so failed, for any cumulative period of
***************************, to supply PENWEST hereunder Product sufficient in
quantity and quality to meet such Authorized Distributor's requirements
therefor, including without limitation the Consignment Inventory described in
Section 6.8.

                  6.2 MYLAN shall purchase and PENWEST shall supply TIMERx for
use in the manufacture of the Product pursuant to this Agreement at the price,
and on the terms, set forth in the Nifedipine XL Agreement. Following the FDA

approval of the Designated Product for sale under the Nifedipine XL Agreement,
quantities to be purchased hereunder shall be added to the estimates and orders
called for under the Nifedipine XL Agreement. If PENWEST notifies MYLAN of an
Authorized Distributor's estimates for Product to be ordered hereunder (whether
before or after FDA approval of the Designated Product for sale in the Mylan
Territory under the Nifedipine XL Agreement), MYLAN shall time its orders for
TIMERx accordingly, as if (for such scheduling purposes) the Authorized
Distributor's requested shipment dates were the dates for MYLAN's sales of the
Designated Product under the Nifedipine XL Agreement. Payment for the TIMERx
shall be made as provided in the Nifedipine XL Agreement.

                  6.3      All sales of Product shall be F.O.B., Morgantown,
West Virginia, or Caguas, Puerto Rico, as MYLAN may specify (but no change from
one location to the other shall be made on less than 45 days' prior written
notice), and PENWEST or the Authorized Distributor (as they may agree) shall
bear all transportation, insurance, taxes, duties, and other costs and risks of
loss, spoilage and damage associated with the shipping and delivery of Product
to PENWEST or the Authorized Distributor.

                  6.4      MYLAN shall be responsible to obtain and maintain any
and all regulatory approvals and licenses for the manufacture of the Product by
it in West Virginia and/or in Puerto Rico and for export from those locations to
the Territory. MYLAN warrants that it will not change or modify the formulation,
manufacturing methods, Bulk Packaging specifications, and/or Product
Specifications as provided hereunder, without at least thirty days' prior
written notice to PENWEST. If MYLAN is required by the FDA to change the
formulation, manufacturing methods, or Product Specifications for the product it
is then making for sale in the MYLAN Territory, or MYLAN otherwise institutes
such changes on its own due to its good faith determination that the same are
necessary or beneficial for the production of the product for sale in the MYLAN
Territory, and if such changes would require the consent of any regulatory
agency in the Territory with regard to the approval or continuing right to use
the same in connection with the Product for sale in the relevant country, MYLAN
will have the following options, with respect to the relevant country(ies) in
the Territory:

                           6.4.1    MYLAN may continue to manufacture the
                                    Product under the prior formulation,
                                    manufacturing methods and Product
                                    Specifications, for supply under this
                                    Agreement, and Section 1.6.2 will be
                                    applicable;

                           6.4.2    where such changes may reasonably be
                                    acceptable to the relevant regulatory
                                    agency(ies), MYLAN may assist PENWEST and
                                    the Authorized Distributor to secure the
                                    approval from the relevant health

                                    regulatory agency(ies) in the Territory for
                                    its making the same changes with respect to
                                    the Product to be supplied under this
                                    Agreement, including without limitation
                                    MYLAN's sharing equally with PENWEST the
                                    costs of all reasonable efforts to secure
                                    such approval(s);

                           6.4.3    MYLAN may permit this circumstance to be a
                                    triggering event that brings into effect the
                                    Contingent License, without the contingency
                                    of the passage of the 30 days specified in
                                    Section 6.1.

MYLAN must pursue at least one of these options with respect to each applicable
country in the Territory at all times, in such a circumstance. MYLAN may pursue
more than one of these options simultaneously as follows: If MYLAN pursues the
option in 6.4.1, it may, but it need not, also pursue the option in 6.4.2 (and,
in either case, the option in 6.4.3 would not be then applicable). If MYLAN
pursues the option in 6.4.3, it may, but it need not, also pursue the option in
6.4.2 (but, in either case, the option in 6.4.1 would not be then applicable).
MYLAN must pursue either 6.4.1 or 6.4.3 in conjunction with 6.4.2, if it elects
to pursue 6.4.2 at all.

                  6.5      At least ********* before an Authorized Distributor
begins sale of the Product, PENWEST shall deliver to MYLAN a written,
non-binding estimate of all the Authorized Distributor's requirements of Product
for the ********* ********* period following the anticipated first commercial
sale by the Authorized Distributor. PENWEST will deliver to MYLAN updates to
such estimates on or before the first day of each ********* thereafter during
the term of this Agreement, which updates may revise estimates previously
submitted and will add estimates for additional months so that at all times such
estimate shall cover the ****************** ********* period following the end
of the ********* in which the estimate is made. MYLAN shall not be obligated to
supply the Authorized Distributor with quantities of the Product during any
********* in excess of ****************** of the quantities estimated in the
Authorized Distributor's highest written estimate applicable to that *********.

                  6.6      PENWEST shall deliver to MYLAN a firm written order
stating the Authorized Distributor's requirements for Product no less than
********* in advance of the requested delivery date therefor. To the extent
practicable, PENWEST will group into single orders all such requirements for
each Authorized Distributor

for the entire Territory for each ********* covered by each such order.

                  6.7 No order for the Product hereunder may be cancelled or
deferred by PENWEST except by written notice delivered to MYLAN at least
********* prior to the scheduled delivery date. No orders may be cancelled or
deferred (even with such ********* notice) without MYLAN's approval if such
cancellation or deferral would reduce PENWEST's or the Authorized Distributor's
purchases for the ********* *************************** of the highest
quantities of the Product estimated as to such
*********.
                  6.8 MYLAN will supply to PENWEST, to be consigned with the
applicable Authorized Distributor, an inventory of approximately *********
production of the Product for such Authorized Distributor, based on PENWEST's
projections given under Section 6.5 for the ********* extending beyond the
********* firm ordering period. This shall be referred to as the "Consignment
Inventory." The initial Consignment Inventory will be drawn down and replenished
on a regular, first-in-first-out basis as the Authorized Distributor takes
deliveries therefrom for its sales. The parties agree that each of them will
*************************** of the MYLAN Cost of Product for the Consignment
Inventory at any given time.

                  6.9 Subject to and conditional upon the failure of MYLAN to
meet the PENWEST Authorized Distributor's requirements for Product as described
in Section 6.1, upon the request of PENWEST, MYLAN grants to PENWEST, as part of
the Contingent License, a license under the MYLAN Manufacturing Technology to
have made by the Authorized Distributor Product for sale in the Territory during
the term of the Authorized Distributor Agreement. Said license shall exist only
for those periods, if any, in which MYLAN is unable to supply the Product, plus
an additional period of up to ********* after MYLAN's notice that it is again
able and ready to supply the Product, during which the Authorized Distributor
will be entitled to exhaust work-in-process and any inventory of finished goods.
Neither PENWEST nor the Authorized Distributor shall have the right to grant a
sublicense hereunder (other than by PENWEST to the Authorized Distributor)
without the prior written consent of MYLAN, which consent shall not be
unreasonably withheld. In order to facilitate the communication of the MYLAN
Manufacturing Technology to the Authorized Distributor and the certification of
its facility as contemplated herein, such that there will be no significant
delay in doing so if PENWEST's rights under this Section 6.9 ever become
applicable, MYLAN will exert reasonable efforts to disclose the MYLAN
Manufacturing Technology to the Authorized Distributor(s) designated for such
purpose by PENWEST, including without limitation by making knowledgeable MYLAN
personnel reasonably available, at a consulting fee not in excess of MYLAN's

actual costs, to consult with the Authorized Distributor or with representatives
of PENWEST who may then consult in turn with the Authorized Distributor, all to
the extent necessary to enable the Authorized Distributor to produce Product
that would otherwise have been supplied by MYLAN. MYLAN will make such
disclosure and provide such consultation within a reasonable time following the
signing of this Agreement, and in any event prior to the filing by the
Authorized Distributor of the first Product License Application for the Product
to be filed by such Authorized Distributor in the Territory, it being
understood, however, that such early consultation shall not give the Authorized
Distributor any right to make any production use of the MYLAN Manufacturing
Technology unless and until the license under this Section becomes applicable,
other than in connection with obtaining the advance regulatory certification in
the Territory of the Authorized Distributor's own facility as an approved
alternate site of manufacture of the Product. This Section and the license
described will survive the termination of this Agreement due to any breach by
MYLAN, for the balance of the Term otherwise provided for in Section 3.1.

                  6.10     In the event that, and for so long as, MYLAN is
unable due to causes beyond its control to supply product to PENWEST and the
Authorized Distributor, and Section 6.9 is instituted, or if Section 6.9 is
instituted as described in 6.4.3, PENWEST shall, in lieu of the price and
payments described in Section 5, pay to MYLAN in consideration of the grant of
such license to the MYLAN Manufacturing Technology an amount equal to *********
of the Sales Royalties received from the Authorized Distributor making the
Product using the MYLAN Manufacturing Technology as permitted under Section 6.9.

                  6.11     If and to the extent that the failure of MYLAN
described in Section 6.9 is due to causes beyond MYLAN's control, and if MYLAN
establishes to PENWEST's reasonable satisfaction that MYLAN is diligently
attempting through its best efforts to remove or resolve such causes such that
MYLAN will be able, or will again be able, to supply the Product as contemplated
herein (which, in the circumstances described in Section 6.4, will require, at a
minimum, that 6.4.2 be applicable and that MYLAN actively and continuously
pursue the option described in 6.4.2), PENWEST shall, in addition to the sums
payable under Section 6.10, pay to MYLAN a further sum equal to *********:

                                    the Product.

hereto and their Affiliates, successors and permitted assigns; provided,
however, that except for assignments or delegations to Affiliates of a party
(which shall not release such party from any of its rights or responsibilities
hereunder), or as part of the transfer of all or substantially all assets to a
single buyer or pursuant to a merger or other corporate reorganization (which in

specifically permitted hereunder, neither party shall assign or delegate any of
its rights or obligations hereunder at any time without the prior written
consent of the other party hereto, which consent shall not be unreasonably
withheld.

         11.5     FORCE MAJEURE:

its reasonable control, whether similar to the foregoing contingencies or not,
said party shall provide written notice of same to the other party. Said notice
shall be provided within five (5) working days of the occurrence of such event
and shall identify the requirements of this Agreement or such of its obligations

         11.8     NO IMPLIED RIGHTS:

         Nothing in this Agreement shall be deemed or implied to be the grant by
one party to the other of any right, title or interest in the Product,
Intellectual Property or any other proprietary right of the other except as is
expressly provided for herein.

         11.9     MODIFICATION BY OPERATION OF LAW:

         If any of the terms or provisions of this Agreement are in or come into
conflict with any applicable law within the Territory then such term or
provision shall be deemed inoperative to the extent it may conflict therewith
and shall be deemed to be modified to conform with such law unless such
modification would render the affected provision inconsistent with or contrary
to the intent of the parties. However, in the event the terms and conditions of
this Agreement are materially altered as a result of this subsection, the
parties shall in good faith attempt to renegotiate said terms and conditions to
resolve any disputes related thereto. Should they be unable to agree on suitable
substantial language the issue shall be referred to arbitration pursuant to
Section 11.1.

between the parties and supersedes all prior drafts or understandings with
respect to its subject matter.

         11.12  COUNTERPARTS:

to be considered an original and taken together as one and the same document.

         11.14    SINGULAR AND PLURAL:

         The singular form of any noun or pronoun shall include the plural when
the context in which such a word is used is such that it is apparent the
singular is intended to include the plural or vice versa.

         11.15    CONFIDENTIALITY:

         In the course of performance under this Agreement, a party may disclose
to the other confidential information belonging to such party in writing, orally
or by demonstration or sample, which information is marked or stated in writing
at or within thirty (30) days after its disclosure to be "confidential" or
"trade secret" information. All such confidential information of a party shall
be maintained in confidence by the other and will not be used by the other party
for any purpose except as authorized hereunder. Each party shall exercise, and
shall cause its Affiliates, sublicensees and consultants to exercise, a
reasonable degree of care and at least the same degree of care as it uses to
protect its own confidential information of similar nature to preserve the
confidentiality of such information of the other party. Each party shall
safeguard such information against disclosure to third parties, including
without limitation employees and persons working or consulting for such party
that do not have an established, current need to know such information for
purposes authorized under this Agreement. This obligation of confidentiality
does not apply to information and material:

                  a. that were properly in the possession of the receiving
party, without any restriction on use or disclosure, prior to receipt from the
other party;

                  b. that are at the time of disclosure hereunder in the public
domain by public use, publication, or general knowledge;

                  c. that become general or public knowledge through no fault of
the receiving party or its Affiliates or sublicensees following disclosure
hereunder;

                  d. that are properly obtained by the receiving party from a
third party not under a confidentiality obligation to the disclosing party
hereto;

                  e. that are independently developed by or on behalf of the
receiving party without the use or assistance of the confidential information of
the other party;

                  f. that consist merely of an idea or conception for the
combination of one or more active ingredients with a controlled-release agent
such as TIMERx; or

                  g. to the extent the same are required to be disclosed by
order of

                                      -22-

   23


any court or governmental authority; provided, however, that the receiving party
shall use its best efforts to give the disclosing party prior notice of any such
disclosure so as to afford the disclosing party a reasonable opportunity to
seek, at the expense of the disclosing party, such protective orders or other
relief as may be available in the circumstances.

         Neither party shall make any public announcement or other publication
regarding this Agreement (whether as to the existence or terms hereof) or the
development work or project hereunder or the results thereof without the prior,
written consent of the other party, which consent shall not be unreasonably
withheld; provided that the foregoing shall not prohibit any disclosure which,
in the opinion of counsel to the disclosing party, is required by any applicable
law or by any competent governmental authority. In no event shall either party
make any disclosure of any such results before a patent application has been
filed with respect thereto, except upon the prior written approval of the other
party.

         11.16  INSPECTION AND AUDIT:

                  a. Each party shall maintain all records attributable to the
matters contemplated herein according to its normal corporate and accounting
procedures. Either party, upon reasonable notice to the other party, shall have
the right to inspect said other party's records, and relevant facilities, during
normal business hours.

                  b. In the event either party receives notice of an inspection
or other notification by a governmental entity, including FDA, relating to the
Products or other matters within the scope of this Agreement, the party in
receipt of such notice of an inspection or other notification will notify the
other party within twenty-four (24) hours of when such notice or notification is
received, and provide to such other party, within seventy-two (72) hours, copies
of all relevant documents, including FDA Forms 482, 483, warning letters, and
other correspondence and notifications as such other party may reasonably
request. PENWEST and MYLAN agree to cooperate with each other during any
inspection, investigation or other inquiry by FDA or any governmental entity,
including providing information and/or documentation as required by the FDA or
other governmental entity. To the extent permissible, PENWEST and MYLAN also
agree to discuss any response to observations or notifications received and to
give the other party an opportunity to comment on any proposed response before
it is made. In the event of disagreement concerning the content or form of such
response, MYLAN shall be responsible for deciding the appropriate form and
content of any response with respect to any of its cited activities and PENWEST
shall be responsible for deciding the appropriate form and content of any
response with respect to any of its cited activities. Each party shall inform
the other of all comments and conclusions received from the governmental
authority.

                  c. In the event PENWEST or MYLAN shall be required or
requested by a governmental authority, or shall voluntarily decide to recall any
Products, MYLAN shall be responsible for coordinating such recall. The parties
shall cooperate fully with one another in connection with any recall. If the
recall is due to any act or omission of PENWEST or the Authorized Distributor,
PENWEST shall reimburse MYLAN for all of the reasonable costs and expenses
actually incurred by MYLAN in connection with the recall including, but not
limited to, costs of retrieving Products already distributed by MYLAN, and such
other costs as may be reasonably related to the recall. If the recall is due to
any act or omission of MYLAN, MYLAN shall reimburse PENWEST and the Authorized
Distributor for any reasonable costs or expenses actually incurred by PENWEST or
the Authorized Distributor in connection with said recall. Pursuant to this
section, the party claiming any reimbursement shall provide the other party with
reasonable documentation of all reimbursable costs and expenses.

         IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
the date set forth above.
