receipt of the invoice. The price may be adjusted between October 1 and October
31 of each year and such adjustment will be made effective January 1 for the
following calendar year by the lesser of (i) ******** or (ii) the increase or
decrease in the Producer Price Index, Pharmaceutical Preparations, Ethical
(Prescription), series code PCU-2834 #1, published by the United States
Department of Labor, Bureau of Labor Statistics, or comparable successor index
(or some other index agreed to in writing by the Parties) during the most recent
******** period preceding each ******** for which such data are available,
provided that POZEN is notified of such adjustment in writing (including the
calculation and data period on which such adjustment is based) by ********
preceding the year in which the price adjustment is effective. The first price
adjustment may be made effective ********. Lek will use commercially reasonable
efforts to keep prices in line with actual increases in cost,********.

(b) ********, POZEN will pay to LPI an additional consideration of
******** on Net Sales by POZEN, its affiliates or Licensees ******** ("Additonal

accuracy of the payment of Additional Consideration made. LPI will have the
right to cause an independent, certified public accountant reasonably acceptable
to POZEN to audit those of POZEN's records required for the purpose of verifying
any amounts payable under this Agreement for the previous year. ********. Such
audits by LPI may be exercised ********, within ninety (90) days of the close of
the previous calendar year, during normal business hours upon reasonable prior
written notice to POZEN. Further, POZEN will secure from its Licensees the right
to audit or have audited such Licensees' records, and to make the findings of
such audits available to LPI in connection with LPI's exercise of its audit
rights under this subsection (c) subject to an agreement on confidentiality
between LPI and such Licensee. Adjustments will be made by the Parties to
reflect the results of such audits within thirty (30) days of the date on which
audit results are made available to the Parties.

(d) If during any payment period during which Additional
Consideration is owed and for ******** after the termination or expiration of
this Agreement, the adjustments to gross sales result in a Net Sales amount that
is a negative number, LPI will repay to POZEN within ten (10) days after receipt
of such Net Sales report an amount corresponding to the amount of Additional
Consideration that POZEN would have had to pay to LPI if such negative Net Sales
number had been positive. ********.

SECTION 6. Warranties.

(a) Lek and LPI warrant that (i) Product manufactured hereunder
will (A) conform to the Specifications, the applicable DMF and Applicable Laws,
including, without limitation, U.S. cGMP regulations and equivalent foreign

(the "IP Warranty"), and that (iii) during the term of this Agreement, the
Manufacturing Process and associated data and information in the DMFs (or such
corresponding portions of regulatory filings as may be required in a given
country, ********) for the Y Product and the X Product conform to the
requirements of the Regulatory Authorities in the ******** and other portions of
the Territory where the Finished Product will be marketed (parts (i), (ii),
(iii) above comprise the "Limited Warranty").

(b) POZEN will advise Lek of any other country in the Territory in
which it intends to effect a commercial launch of the Finished Product. Lek and
LPI will thereafter advise POZEN whether they are willing to make the
representation contained in clause (ii) of sub-paragraph (a) with respect to
such country in the Territory. In the event Lek has satisfied itself that the
Manufacturing Process used in the manufacture of Product by Lek hereunder, does
not infringe upon the intellectual property rights of any person or entity or
constitute a misappropriation of the trade secrets or other intellectual
property rights of any person or entity in any country in addition to those set
forth in clause (ii) of subparagraph (a), Lek will promptly notify POZEN thereof
and the country list in clause (ii) of this sub-paragraph will thereafter be
deemed to be amended to include such country.

(c) OTHER THAN THE LIMITED WARRANTY ABOVE, LEK MAKES NO WARRANTIES,
EXPRESS OR IMPLIED, WITH RESPECT TO THE PRODUCTS, INCLUDING, WITHOUT LIMITATION,
ANY WARRANTY OF MERCHANTABILITY OR WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE.

(d) During the term of the Agreement, if and when a third party is
granted or asserts intellectual property rights related to the Manufacturing
Process, Lek will evaluate such intellectual property and will either (i)
confirm to POZEN and its Licensees that such process does not infringe any such
third party intellectual property, or (ii) use commercially reasonable efforts
to (1) develop an alternative noninfringing process in a timely fashion and
according to the terms provided in Section 10(b) and/or 10(c), as applicable, or
(2) take such other action as may be necessary to make such process
non-infringing.

SECTION 7. Delivery. LPI will deliver Product DDU (Incoterms 2000) at the
U.S. or European facility designated by POZEN, according to the schedule and in
the amounts specified in the purchase orders provided by POZEN and under the
provisions set out in Section 2 or 3, as applicable. Lek will test each batch of
Product and supply POZEN with a Certificate of Analysis confirming that such
batch meets the Specifications.

SECTION 8. Acceptance Testing; Rejection. If a shipment of a lot of Product
or any portion thereof fails to conform to the Product Warranty, then POZEN will
have the right to reject such nonconforming shipment of the Product or the
nonconforming portion thereof, as the case may be, in accordance with the
following:

(a) Patent Defect.

(i) POZEN will give written notice to Lek and LPI of its
rejection (or its Licensee's or customer's rejection) hereunder, within sixty
(60) days after delivery by LPI to POZEN's or its Licensee's or customer's
designated facilities of any shipment of any Product containing a Patent Defect,
specifying the grounds for such rejection and, if such rejection is made for
failure of the Product to conform to Specifications, deliver to Lek samples of
the rejected Product.

(ii) After receipt of such notice and samples from POZEN, Lek
will be permitted, for a period of fourteen (14) business days, to analyze the
Product rejected by POZEN

for nonconformity to the Specifications, and to present its findings with
respect to such Product to POZEN. If the parties cannot agree on whether the
Product in question conforms to such Specifications within fourteen (14)
business days of Lek's receipt of POZEN's written notice of rejection, an
independent laboratory or independent consultant selected by POZEN from the list
attached hereto as Exhibit F (as amended from time to time by the parties in
writing) ********, will analyze both POZEN's and Lek's samples of the Product in
question. Each Party may have representatives present during the independent
analysis. The definitive results of such analysis by the independent laboratory
or independent consultant will be binding on the parties.

(iii) If the shipment of Product in question is determined to be
nonconforming with respect to the Specifications or otherwise fails to conform
to the Product Warranties, such nonconforming Product will be held for Lek's
disposition, or will be returned to Lek (unless prohibited by Regulatory
Authorities), ********, as directed by Lek, ********. Lek will then use its
commercially reasonable efforts to replace each nonconforming shipment of
Product, or the nonconforming portion thereof on a batch-by-batch basis, with
conforming Product as soon as reasonably practicable after receipt of notice of
rejection thereof or will promptly provide POZEN with a credit therefor, at
POZEN's election. If the Product was improperly rejected, POZEN will be required
to accept ******** such Product and ********.

(b) Latent Defect.

(i) If Lek becomes aware of a Latent Defect in any shipment of
Product, Lek will immediately notify POZEN as to the shipment involved, and, at
POZEN's election, such Product will be deemed rejected as of the date of such
notice, and Lek will use commercially reasonable efforts to replace each
nonconforming shipment, or the nonconforming portion thereof, with conforming
Product as soon as reasonably practicable after receipt of notice of rejection
thereof, or will promptly provide POZEN with a credit therefor, at POZEN's
election.

(ii) POZEN will give written notice to Lek of its rejection (or
its customer's or Licensee's rejection) hereunder, within thirty (30) days after
POZEN's (or its customer's or Licensee's) discovery that a shipment of any
Product contains a Latent Defect, specifying the grounds for such rejection, and
if such rejection is made for failure of the Product to conform to
Specifications, deliver to Lek samples of the rejected Product.

(iii) After receipt of such notice and samples from POZEN, Lek
will be permitted, for a period of fourteen (14) business days, to analyze the
Product rejected by POZEN for nonconformity to the Specifications, and to
present its findings with respect to such Product to POZEN. If the parties
cannot agree on whether the Product in question conforms to such Specifications
within fourteen (14) business days of Lek's receipt of POZEN's written notice of
rejection, an independent laboratory or independent consultant selected by POZEN
from the list attached hereto as Exhibit F (as amended from time to time by the
parties in writing) ********, will analyze both POZEN's and Lek's samples of the
Product in question. Each Party may have representatives present during the
independent analysis. The definitive results of such analysis by the independent
laboratory or independent consultant will be binding on the parties.

(iv) If the shipment of Product in question is determined to be
nonconforming with respect to the Specifications or otherwise fails to conform
to the Product Warranties, such nonconforming Product will be held for Lek's
disposition, or will be returned to Lek, ********, as directed by Lek, ********.
Lek will then use its commercially reasonable efforts to replace each
nonconforming shipment of Product, or the nonconforming portion thereof on a
batch-by-batch basis, with conforming Product as soon as reasonably practicable
after receipt of notice of rejection thereof or will promptly provide POZEN with
a credit therefor, at POZEN's election. If the Product was improperly rejected,
POZEN will be required to accept ******** such Product ********.

(c) Recalls. In the event a Party believes it may be necessary to
conduct a recall, field correction, market withdrawal, stock recovery, or other
similar action with respect to any Product that was sold by LPI to POZEN under
this Agreement or thereafter by POZEN and/or its Licensees to their customers (a
"Recall"), Lek and POZEN will consult with each other as to how best to proceed,
it being understood and agreed that the final decision as to any such Recall
with respect to Finished Product will be made by POZEN or its Licensees, and the
final decision as to any such Recall with respect to Product that has not yet
been processed into Finished Product will be made by Lek. The Party whose
actions resulted in the Recall, if attributable to a Party, will bear any and
all associated costs and expenses in connection with any such Recall. If the
Recall is attributable to a breach of warranty by Lek or LPI or the failure of
Product supplied by Lek or LPI to meet Specifications, any and all associated
costs and expenses incurred as a result of such Recall will be borne by Lek. If
the Recall is attributable to a determination by the FDA that the Finished
Product is no longer safe and effective or due to adverse drug events which are
not attributable to a breach of warranty by Lek or LPI or the failure of Product
supplied by Lek or LPI to meet Specifications, any and all associated costs and
expenses incurred as a result of such Recall will be borne by POZEN. In the
event neither Party's actions are attributable, directly or indirectly, to the
Recall, and the Recall is not attributed to adverse drug events or a
determination by the FDA that the Finished Product is no longer safe and
effective any and all associated costs and expenses incurred as a result of such
Recall will be borne by the parties in proportion to their respective revenues
from Net Sales in that country of the Territory.

(d) Adverse Drug Events. Any adverse drug event or reaction complaint
reports or any other reports or information indicating that the Product within
any Finished Product has any toxicity, sensitivity reactions, or is otherwise
alleged to cause illness or injury of any kind or is adulterated or misbranded
will be reported promptly by POZEN to Lek, or as otherwise may be required under
any applicable laws, rules or regulations, with copies of any such written
reports, and Lek will thereafter expeditiously investigate the information
contained in such reports and communicate such results promptly to POZEN upon
conclusion of such investigation.

SECTION 9. Confidential Information.

(a) During the term of this Agreement and seven (7) years after
termination of the Agreement, all Confidential Information furnished by POZEN to
Lek or LPI, or by Lek or LPI to POZEN, relating to the subject matter hereof,
will be kept confidential by the party receiving said confidential information
and the party receiving said Confidential Information will

not make use of said Confidential Information, except for purposes authorized by
the Agreement, nor disclose the same to any person or firm unless previously
authorized in writing to do so; provided, however, that the party receiving said
Confidential Information may disclose same to its responsible officers,
employees, consultants and Licensees who require said information for the
purposes contemplated by this Agreement, provided that said officers, employees
and consultants and Licensees have assumed obligations of confidentiality not
less stringent than those contained herein.

(b) Any other provision hereof to the contrary notwithstanding, it is
expressly understood and agreed by the parties hereto that the obligations of
confidence and non-use herein assumed will not apply to any information which:

(i) is lawfully, at the time of disclosure or thereafter so
becomes, a part of the public domain;

(ii) was otherwise in the receiving party's lawful possession
prior to disclosure, as shown by its written record;

(iii) is hereafter lawfully disclosed to the receiving party by a
third party who is not in violation of an obligation of confidentiality to the
disclosing party relative to said information;

(iv) is, by mutual agreement of the parties hereto, released from
a confidential status; or

(v) results from research and development by the receiving Party
without use and by persons without access to Confidential Information of the
other Party as shown by competent evidence including, but not limited to,
records contemporaneously maintained with such research and development.

(c) Either Party may disclose Confidential Information of the other
if required by legal process; provided, in each case the receiving Party timely
informs the disclosing Party and uses its best efforts to limit the content of
the disclosure, limit the disclosure to those specific legal parties requesting
such information, maintain confidentiality to the extent possible and permit the
disclosing Party to attempt by appropriate legal means to limit such disclosure
in terms of content and recipient.

(d) POZEN or its Licensees may disclose Lek Confidential Information,
including, without limitation, the DMFs, to government or other regulatory
authorities to the extent that such disclosure is reasonably necessary to obtain
marketing authorization for products containing DHE. POZEN or its Licensees may
disclose Lek Confidential Information (other than the DMFs) to other
manufacturers in the supply chain of the Finished Product for the sole purpose
of the manufacture of the Finished Product, provided that such third party
manufacturers are bound by confidentiality obligations not less stringent than
those contained herein, and that Lek is made a third party beneficiary of such
confidentiality agreements. POZEN and its Licensees will have the right to
access and reference the X Product DMF and the Y Product DMF solely for the
purpose of developing and commercializing products containing DHE.

(e) Additionally, POZEN may disclose this Agreement (i) to
prospective licensees provided such prospective licensees have a legal
obligation to protect the confidentiality of said disclosure and (ii) as may be
required by applicable law in connection with securities or other public
filings.

SECTION 10. Process Implementation; Quality Control.

(a) With respect to each Finished Product, Lek will permit
representatives of POZEN or its designees, upon sixty (60) days prior notice,
(i) two (2) times per year prior to and for two (2) years after final Regulatory
Approval to market such Finished Product and (ii) one (1) time per year
thereafter during the term of this Agreement, to inspect the Lek Facility, batch
records, standard operating procedures and all other records reasonably relating
to the Product manufacturing process. Such inspections will take place during
regular business hours and with the least possible disruption of Lek's
operations. POZEN will discuss the results of any inspection with Lek. Any
inspection by POZEN, if it occurs, does not relieve Lek of its sole obligation
to comply with all Applicable Laws and does not constitute a waiver of any right
otherwise available to POZEN. In the event that Lek's Quality Control is
preparing for another previously confirmed audit with the FDA or other
Regulatory Authority, POZEN's audit pursuant to this subsection (a) may be
postponed for a reasonable period. POZEN will have the right to request copies
of and/or examine all batch records generated in the manufacture, storage and
shipment of Product under this Agreement.

(b) Lek will provide POZEN with written notice of any planned change
that is pertinent to the manufacture, testing, or storage of Product, including
but not limited to changes in the Manufacturing Process, Specifications, or
analytical methods. Within thirty (30) days from the date of receipt of such
written notice from Lek, POZEN will notify Lek if such planned change in POZEN's
reasonable judgment requires notification of a Regulatory Authority or
additional testing of Product or Finished Product. If POZEN so notifies Lek, the
Parties will develop a change implementation plan (including, without
limitation, a regulatory strategy related thereto) within sixty (60) days from
the date of POZEN's notice to Lek, and Lek will implement such planned change
only after the completion of such change implementation plan. Any such change
implementation plan will take into account the time required for any actions or
filings required to comply with applicable regulatory requirements. In the event
POZEN does not provide Lek with such written notice within the designated thirty
(30) day period, Lek is free to proceed with its planned change.

(c) When required or requested to do so by a Regulatory Authority,
POZEN may in writing modify the Specifications in Exhibit B, or request a change
in the Manufacturing Process, and the Parties will agree to a specific written
procedure and the costs necessary to implement any such changes related to the
Specifications or Manufacturing Process. Additionally, POZEN may, from time to
time, in writing suggest other modifications of the Specifications in Exhibit B
or the Manufacturing Process, and in the case of Lek's approval (which will not
be unreasonably withheld), the Parties will agree to a specific written
procedure and the costs necessary to implement such other changes to the
Specifications.

(d) Lek will submit to POZEN the DMF annual reports, including
information on changes within any DMF, within thirty (30) days of any such
reports and/or filing any such changes with any Regulatory Authority.

SECTION 11. Drug Master File; Regulatory Matters.

(a) Lek will develop a Manufacturing Process and file a X Product DMF
that satisfies the ******** parameters of the Specifications in Exhibit B-2 in
those countries where POZEN or its Licensees intend to file a Finished Product
containing the X Product for Regulatory Approval. POZEN and/or its Licensees
will advise Lek in writing of the countries in which it intends to file for
Regulatory Approval of a Finished Product containing the X Product at least
twelve months prior to filing. In the event that significant deviations from the
Specifications in Exhibit B-2 are necessary to meet regulatory requirements in a
specific country, the Parties will agree to a specific written procedure to
modify the Specifications in Exhibit B-2 and the costs necessary to implement
any such changes.

(b) Lek will at all times during the term of this Agreement maintain
the DMFs in current and active status, and will regularly provide the Regulatory
Authorities with all reports and information necessary to keep such DMFs current
and in force.

(c) Lek will inform POZEN of the results of any inspection of the Lek
Facility by a Regulatory Authority that is pertinent to the manufacture,
testing, or storage of Product or which could affect the manufacture and supply
of the Product by Lek or LPI, regardless of whether such inspection was
conducted in connection with the Product manufacture, at the conclusion of each
calendar year. If such an inspection is in connection with the Product
manufacture, Lek will additionally provide POZEN with a copy of the Regulatory
Authority final report within three (3) days of Lek's receipt of such report.
Notwithstanding the foregoing, Lek will within three (3) days of receipt provide
POZEN with copies of any Form No. 483 notification, Enforcement Inspection
Reports, Notice of Adverse Finding, or their analogous forms from any Regulatory
Authorities ("Warning Letters") and any subsequent responses by Lek or the
Regulatory Authorities relating to the manufacture of Product or the Lek
Facility. Lek will have the right to redact from any documentation provided to
POZEN under this subsection (c) any information that is specific to products
other than the Products. In addition to the audit as provided in Section 10(a),
in the event that (i) Lek receives any Warning Letters relating to the Lek
Facility or (ii) POZEN has properly rejected a shipment of Product in accordance
with the rejection procedures of Section 8(a) or (b) (including, if necessary,
after following the independent laboratory testing procedures set forth therein)
for failure to meet Specifications or otherwise to conform with the Product
Warranties, POZEN will have the right to conduct an additional audit according
to the terms specified in Section 10(a).

(d) Lek will notify POZEN of any production issues or other
information of which Lek becomes aware which may cause the Product to no longer
conform with Regulatory Approvals or Applicable Laws or materially affect the
ability of Lek or LPI to supply Product in accordance with this Agreement. Lek
agrees to inform POZEN within three (3) days of receipt of notice of inquiry or
inspection activity by any Regulatory Authority from a country in which POZEN or
its Licensees plan to submit or have submitted dossiers for Regulatory Approval
in regard to Product, and will provide POZEN with copies of any written
communications received

from Regulatory Authorities related to the manufacture of Product. Lek will
furnish to POZEN any proposed response to inquiries from Regulatory Authorities
in sufficient time to give POZEN a reasonable opportunity to review, discuss,
and comment on the inquiry and the proposed response. Lek will consider POZEN's
comments and appropriately address POZEN's concerns in its response.

(e) Neither Party will use in any capacity, in connection with any
manufacturing or other services to be performed under this Agreement, any
individual who has been debarred pursuant to the U.S. Federal Food, Drug and
Cosmetic Act or who is subject to an action, suit, claim, investigation or legal
or administrative proceeding that could reasonably be expected to lead to a
debarment of Lek, POZEN or any person performing manufacturing or other services
hereunder. Either Party will, if so requested by the other Party, prepare and
submit a certification statement as necessary to satisfy the requirements of the
U.S. Federal Food, Drug and Cosmetic Act. Either Party agrees to immediately
inform the other Party in writing if any person who is performing services
hereunder is debarred or if such person becomes subject to an action, suit,
claim, investigation or legal or administrative proceeding that could lead to a
debarment of such person.

exist as to the interpretation of the regulatory requirements applicable to the
Product and its manufacture. If such difference of opinion exists between the
Parties at any time during the term of this Agreement, the Parties will discuss
in good faith how to reconcile such differences. If the Parties are unable to
come to an agreement thereon after good faith negotiations, POZEN will have the
right to require Lek to make such changes to the Product and its manufacture,
and to provide such data and documentation as it reasonably believes necessary
to comply with regulatory requirements. Lek will use commercially reasonable
efforts to comply with POZEN's request. ********.

SECTION 12. Indemnification; Insurance.

(a) Lek's Indemnity Obligations. Except as set forth in Section 12(d)
below, Lek will indemnify, defend and hold harmless POZEN and its affiliates and
Licensees, and their respective successors and permitted assigns (and the
respective officers, directors, stockholders, partners and employees of each),
from and against any and all losses, liabilities, claims, actions, proceedings,
damages and expenses (including without limitation reasonable attorneys' fees
and expenses) (herein "Damages") resulting from any third party claims or suits
arising out of (i) any breach by Lek of any warranty, representation, covenant
or obligation hereunder, (ii) a claim that the manufacturing process used to
manufacture the Product infringes the intellectual property rights of a third
party in the ********, and such other countries as may be included within clause
(ii) of the Limited Warranty in Section 6(a) with agreement between the parties
as provided in Section 6(b), or (iii) product liability claims relating to
Product supplied by Lek hereunder to the extent such claims arise out of a
failure of the Product to conform to the Product Warranties.

(b) POZEN's Indemnity Obligations. Except as set forth in Section
12(d) below, POZEN will indemnify, defend and hold harmless Lek and its
affiliates, and their respective successors and permitted assigns (and the
respective officers, directors, stockholders,

partners and employees of each) from and against any and all Damages resulting
from any third party claims or suits arising out of (i) any breach by POZEN of
any warranty, representation, covenant or obligation hereunder, (ii) a claim
that the manufacture, marketing, use, distribution or sale of Finished Products
(other than the manufacturing process used to manufacture the Product contained

intends to claim indemnification under this Section 12 will notify the other
Party (the "indemnitor") promptly in writing of any action, claim or liability
in respect of which the indemnitee believes it is entitled to claim
indemnification, provided that the failure to give timely notice to the
indemnitor will not release the indemnitor from any liability to the indemnitee
except to the extent the indemnitor is prejudiced thereby. No such claim will be
settled other than by the Party defending the same, and then only with the
consent of the other Party which will not be unreasonably withheld; provided
that the indemnitee will have no obligation to consent to any settlement of any
such action or claim which imposes on the indemnitee any liability or obligation
which cannot be assumed and performed in full by the indemnitor, and the
indemnitee will have no right to withhold its consent to any settlement of any
such action or claim if the settlement involves only the payment of money by the
indemnitor or its insurer.

(d) Limitations on Indemnification. Notwithstanding any contrary
provision herein:

(i) Neither Party will be entitled to indemnification with
respect to any claim or suit to the extent such claim or suit results from (A)
its own negligence or willful misconduct, or (B) any action to which it has
consented in writing; and

(ii) NEITHER PARTY WILL BE LIABLE TO THE OTHER FOR ANY PUNITIVE,
CONSEQUENTIAL, INCIDENTAL OR INDIRECT DAMAGES, INCLUDING DAMAGES FOR LOST
PROFITS, LOSS OF OPPORTUNITY OR USE OF ANY KIND, SUFFERED BY THE OTHER PARTY,
WHETHER IN CONTRACT, TORT OR OTHERWISE.

(e) Product Liability Insurance.

(i) Lek and POZEN will each maintain comprehensive product
liability insurance to cover its indemnification obligation provided in Section
12 in the annual aggregate amount of ********, combined single limit for bodily
injury and property damage per occurrence and up to ******** immediately prior
to the Date of First Commercial Sale for costs associated with a recall, per
occurrence and in the annual aggregate. Each of Lek and POZEN will maintain such
insurance during the term of this Agreement and thereafter for so long as it
customarily maintains insurance for itself for similar products and activities.
Each of Lek and POZEN will cause the other to be named as an additional insured
under such insurance. Each of Lek and POZEN will provide the other with at least
thirty (30) days notice of any cancellation, termination or change in such
insurance. Each Party shall provide the other Party with

certification from its insurance company indicating its compliance with the
requirements of this Section 12(e) ("Certificate of Insurance") as soon as is
reasonably practicable. Each Party shall provide to the other Party an updated
Certificate of Insurance on an annual basis during the term of this Agreement.

(b) By Lek.

(i) At any time following the ********* anniversary of the Date
of First Commercial Sale, Lek may cancel this Agreement upon ******** written
notice to POZEN if Lek decides to permanently cease the manufacture of DHE.

subsection (i) above, Lek will have the right to accelerate the delivery of
Product to be supplied prior to the termination date in such quantities as
determined by POZEN's and its Licensees' forecasted requirements for each year
of the notice period, provided that the quantities of Product delivered to cover
such requirements for a particular year of the notice period will have a shelf
life of at least three (3) years as of the year of the notice period for which
such Product is required by POZEN or its Licensee. If a ******** shelf life is
not attainable, Lek will deliver the Product in each remaining year of this
Agreement according to the normal delivery schedule procedure outlined in this
Agreement or to a delivery schedule otherwise agreed upon by the Parties.

(iii) Promptly upon providing notice of termination as provided
in subsection (i) above, Lek will transfer both the open and closed portion of
the DMF, which uses ergotamine tartrate as the starting material for the
manufacturing process of the Product, to POZEN and/or its Licensees to be used
in accordance with Section 9 hereof. The Parties will agree to a specific
written procedure and the costs necessary to implement such transfer to POZEN.
Lek will make its employees available to POZEN for a period of ******** after
the transfer of the DMF to consult with POZEN or its designated contract
manufacturer on the implementation of the manufacturing process. If such
consulting activity requires travel by Lek employees to the new manufacturing
site, POZEN will reimburse Lek for time and reasonable travel expenses based on
Lek's standard hourly rate.

(iv) Upon cancellation of this Agreement by Lek under this
subsection (b), Lek will continue to supply POZEN with ergotamine tartrate under
terms mutually agreed by the parties, and if Lek decides to permanently cease
the manufacture of ergotamine tartrate, Lek will transfer the technical data
package relating to the manufacture of ergotamine tartrate to POZEN and/or its
Licensees to be used subject to Section 9 hereof, in addition to the DMF
transferred by Lek pursuant to subsection (b)(iii) above.

(i) POZEN may cancel this Agreement upon written notice to Lek
if POZEN or its Licensees decide to abandon the filing of all Regulatory
Approvals or to withdraw the Finished Product in all countries of the Territory.
Such cancellation will be effective immediately without further obligation
except for any Product in process or unshipped Product either of which have been
manufactured by Lek at POZEN's request as substantiated by POZEN's purchase
orders prior to receipt of the notice of cancellation and except as detailed
below in this Section 13(c)(i). In any such case, POZEN will provide Lek with as
much notice as reasonably possible regarding the possibility of cancellation.
*********.

(ii) POZEN may cancel this Agreement upon written notice to Lek
in the event that Lek fails to supply ******** the Product ordered by POZEN in
accordance with Section 3(f) ******** after the scheduled delivery ********.

(iii) POZEN may cancel this Agreement upon written notice to Lek
in the event that (1) Lek is unable (A) to develop a manufacturing process for X
Product meeting the Specifications in Exhibit B-2 by ********, or (B) to modify
such process ******** after a change of such Specifications may be required to
be made or requested by POZEN for regulatory or competitive marketing reasons,
********.

(iv) At any time following the ******** anniversary of the Date
of First Commercial Sale, POZEN may cancel this Agreement upon ******** written
notice to Lek.

Lek within ******** thereafter develops a manufacturing process for X DHE that
is substantially similar to the X Product as described in the Specifications
provided in Exhibit B-2, Lek will notify POZEN thereof in writing and will offer
POZEN to enter into an exclusive supply agreement for such product on terms not
less favorable to POZEN than those provided for with respect to the X Product in
this Agreement. If POZEN is interested in entering into such agreement, the
Parties will negotiate and execute a substantially similar supply agreement for
such product ******** thereafter. If POZEN declines to enter into such
relationship or does not respond to Lek's offer ******** after receipt thereof,
Lek will be free to sell such product to third parties without further
obligation to POZEN.

SECTION 14. Termination.

(a) Default. If either Party materially defaults in the performance
of a material provision of this Agreement, and does not remedy that default to
the other Party's reasonable satisfaction ******** after receipt of a notice of
default, the Party not in default may terminate this Agreement. Termination of
this Agreement pursuant to this Section 14(a) will not affect any other rights
or remedies that may be available to the nondefaulting Party.

(b) Bankruptcy. Either Party may terminate this Agreement in the
event the other Party is declared bankrupt or insolvent, or makes an assignment
for the benefit of its creditors, or if a receiver is appointed or any
proceedings are commenced, voluntary or involuntary, by or against such bankrupt
or insolvent Party under any bankruptcy or similar law

(other than a reorganization under Chapter 11 of the United States Bankruptcy
Code or any successive provision), and, if instituted by a third party against a
Party, such status is not cured within sixty (60) days from its occurrence.

(c) Force Majeure. Neither Party will be held liable or responsible
for failure or delay in fulfilling or performing any of its obligations under
this Agreement in case such failure or delay is due to any condition beyond the
reasonable control of the affected Party including, without limitation, Acts of
God, strikes or other labor disputes, war, riot, earthquake, hurricane, fire,
flood, governmental regulations or actions (a "Force Majeure Event"). Such
excuse will continue only as long as the Force Majeure Event continues;
provided, that if the Force Majeure Event continues for a period of more than
one hundred eighty (180) days, the other Party will have the right to terminate
this Agreement with written notice effective upon receipt. The Party affected by
the Force Majeure Event will give immediate notice to the other Party of the
extent and nature thereof and will use its best efforts to mitigate the
consequences of the occurrence of such Force Majeure Event.

SECTION 15. Effects of Cancellation or Termination.

(a) Accrued Obligations. The cancellation or termination of this
Agreement will not affect any payment obligation, fulfillment of purchase order
obligation or other obligation that accrued prior thereto with the exception of
the obligations specifically excused in Sections 13 and 14.

(b) Transfer of Manufacturing Information. If and when Lek gives
notice of termination of this Agreement pursuant to Section 13(b)(i), Lek will
provide POZEN with a complete copy of the DMFs and reference standards necessary
to transfer manufacturing (synthesis) and analytical methods associated with the
Product to another manufacturer, and POZEN, its Licensees, or their respective
contract manufacturers will have the right to practice the manufacturing process
described in such DMFs to manufacture the Finished Product as of the Effective
Date of such termination.

(c) Survival. The rights and obligations of the Parties under Section
6, 9, 11, 12, 15, 16, 20, 21, 22 and 23 of this Agreement will survive any
termination or expiration of this Agreement.

SECTION 16. Waiver. Failure of either Party to insist in any instance on
the strict performance of any covenant, term, provision or condition hereunder,
or to exercise any option herein contained, will not be construed as a waiver of
such covenant, term, provision, condition or option in any other instance.

SECTION 17. Assignment. This Agreement may not be assigned by a Party
without the prior written consent of the other Parties except that a Party may
assign this Agreement without the other Parties' consent to any entity that
acquires substantially all of its stock, assets or business. In addition, POZEN
may assign this Agreement without Lek's or LPI's consent, in whole or in part,
to (i) any affiliate of POZEN, defined as any corporation controlled by, or
under common control with, POZEN, or (ii) any partnership or joint venture or
other entity directly or indirectly controlled by, or under common control with,
POZEN, or (iii) a

Licensee that has the right to commercialize the Finished Product, and that is
not a company listed in Exhibit E. Any permitted assignee will assume all
obligations of its assignor under this Agreement.

SECTION 18. Relationship of the Parties. The relationship between Lek and
LPI, on the one hand, and POZEN, on the other hand, created by this Agreement is
solely that of independent contractors. This Agreement does not create an
agency, partnership or joint venture and nothing in this Agreement authorizes a
Party to act for, represent or bind any other or any of its affiliates, except
to the extent expressly provided in this Agreement.

SECTION 19. Further Assurances. Lek, LPI and POZEN agree to execute,
acknowledge and deliver all further documents, and perform all other acts
reasonably necessary and appropriate to fulfill the purposes of this Agreement.

SECTION 20. Use of Party's Name. Neither Party may use the other Party's
name, trade names or trademarks in any manner without the express written
consent of that Party. Notwithstanding the above, as may be required by
applicable law, the Parties and their affiliates will be permitted to use the
other Party's name and to disclose the existence and terms of this Agreement in
connection with securities or other public filings. POZEN may additionally
disclose this Agreement in connection with its financing and licensing
activities.

SECTION 21. Applicable Law. This Agreement will be construed and enforced
in accordance with the laws of the United States of America, State of North
Carolina, without regard to its conflict of laws provisions and without regard
to the United Nations Convention on the International Sale of Goods.

SECTION 22. Dispute Resolution. Any material disputes or disagreements
between the Parties arising hereunder will be referred to the Chief Executive
Officer of POZEN, the President of the Board of Management of Lek and the
President and CEO of LPI or their designees for good faith resolution for a
period of thirty (30) days. If the Parties are not able to settle their dispute
or disagreement during such thirty (30) day period, such dispute or disagreement
will be settled by arbitration in accordance with the then existing Commercial
Arbitration Rules of the American Arbitration Association. Upon request by a
Party, arbitration will be by a panel of three arbitrators within thirty (30)
days of such arbitration request. Lek and LPI will jointly select one
arbitrator, POZEN will select one arbitrator, and the third will be mutually
agreed upon in writing by the Parties. In any such arbitration, the Parties will
select a panel with relevant experience in the pharmaceutical industry. Judgment
upon the award rendered by the panel will be final and nonappealable and may be
entered in any court having jurisdiction thereof. The parties will be entitled
to all discovery in like manner as if the arbitration were a civil suit in the
federal district courts located in Wilmington, North Carolina. Any arbitration
will be held in Wilmington, North Carolina, unless the parties hereto mutually
agree in writing to another place. The prevailing Party in any arbitration
action to enforce or interpret this Agreement will be entitled to recover
reasonable costs and attorneys' fees from the non-prevailing Party.

SECTION 23. Entire Agreement. This Agreement, with its attached Exhibits,
constitutes the entire agreement between the Parties concerning this subject
matter and

supersedes all previous agreements, whether written or oral. This Agreement may
not be modified orally, and no modification will be effective unless in writing
signed by duly authorized representatives of both Parties. Any preprinted
provision on any forms used by a Party in connection with shipments hereunder
(e.g., purchase orders, acknowledgments, invoices, etc.) will be of no effect
despite any provision to the contrary, unless that provision specifically refers
to and purports to modify this Agreement and that writing is signed by duly
authorized representatives of Lek, LPI and POZEN.

In Witness Whereof, the Parties have executed this Agreement effective as
of the Effective Date.
