                  (b) Neither Leiner nor any of its Affiliates  shall,  directly
or  indirectly,  market or sell the Product (i) to any of the Persons  listed on
SCHEDULE 3.3 hereto,  (ii) bearing  prescription  labeling to any Person,  (iii)
outside of the Territory or (iv) to any Person in the  Territory  where it knows
or has  reason to  believe  that  such  Product  will be  resold by such  Person
(directly  or  indirectly)  outside  of  the  Territory.   Genpharm  and  Leiner
understand  and agree that Par shall  retain the  exclusive  right to market and
sell the Product  (A) to the  customers  listed on  SCHEDULE  3.3 hereto and (B)
bearing prescription labeling to any Person.

                  3.4  FORECASTS  AND  FIRM  ORDERS.  Leiner  shall  provide  to
Genpharm and Par, quarterly (at least sixty (60) calendar days in advance of the
commencement  of the  first  calendar  month  forecasted  thereunder),  a twelve
(12)-month rolling forecast of Leiner's  estimated  requirements of the Product,
which forecast  shall  represent a commitment of Leiner to purchase the quantity
of Product  projected for the first three months  thereunder and a commitment to
purchase  from Genpharm (or  Genpharm's  designee) any raw materials not used or
resold  by the  Manufacturer  but  ordered  by the  Manufacturer  in  reasonable
reliance on the quantity of Product  forecasted by Leiner for the fourth,  fifth
and sixth months forecasted  thereunder.  Such raw material  purchased by Leiner
shall be delivered to Leiner  promptly  after  Leiner's  payment  therefor,  and
Leiner  shall pay  Genpharm  promptly  upon  receipt of  Genpharm's  invoice for
applicable freight,  insurance and taxes, imposts or duties levied upon the sale
of the raw  materials  by  Genpharm  to Leiner.  Subject to the  foregoing,  all
forecasts  are  estimates  only,  and Leiner shall be bound only to purchase the
Product  pursuant  to  purchase  orders  submitted,  or deemed  hereunder  to be
submitted,  by it to Genpharm  (and Par).  Leiner  shall  deliver the first such
forecast as soon as possible and in any event within  thirty (30)  calendar days
after the  Effective  Date,  and Leiner  shall,  subject  to the first  sentence
hereof,  deliver  the  updated  and  extended  forecasts  every three (3) months
thereafter.

                  3.5  INSUFFICIENCY OF SUPPLY. In the event that Genpharm shall
fail to supply Leiner's Reasonable and Consistent  Requirements  hereunder for a
period exceeding one hundred twenty (120)  consecutive days and Leiner is not in
breach of this  Agreement,  Leiner  may, in its  discretion,  elect to cause the
Product to be manufactured  for Leiner by a third party of Leiner's  choosing (a
"Third  Party  Source").  At the end of such 120-day  period,  Leiner shall give
Genpharm  not less than sixty (60) days notice of Leiner's  intent to cause such
Product to be  manufactured  by a Third Party Source for Leiner.  If Genpharm is
able to demonstrate to Leiner,  in Leiner's  reasonable  good faith  discretion,
that it can meet Leiner's  Reasonable  and Consistent  Requirements  within such
sixty  (60) day  period,  then  Leiner  shall  continue  to  procure  all of its
requirements of the Product from Genpharm.  If Genpharm is unable to demonstrate
to  Leiner,  in  Leiner's  reasonable  good faith  discretion,  that it can meet
Leiner's  Reaonable  and  Consistent  Requirements  within  such  sixty (60) day
period,  and Leiner is not in breach of this  Agreement,  then Leiner shall have
the right to secure  additional  supply of the Product from a Third Party Source
to the extent that Genpharm is unable to meet Leiner's Reasonable and Consistent
Requirements, only until such time as Genpharm is able to demonstrate to Leiner,
in  Leiner's  reasonable  good  faith  discretion,  that  it can  meet  Leiner's
Reasonable and Consistent Requirements hereunder.

non-prevailing  party. Leiner shall not dispose of any Product claimed by it not
to comply with the terms and  conditions  hereof until final  resolution  of any
dispute with respect thereto.  Genpharm shall cause the Manufacturer to promptly

the Manufacturer  to, maintain true and complete books of account  containing an
accurate  record of all data  necessary  for proper  assessment  of the Transfer

hereof,  Genpharm shall,  and shall cause the  Manufacturer  to, provide Par and
Leiner  with the  right,  through an  independent  certified  public  accountant
(except any to whom Genpharm or the Manufacturer has a reasonable objection), to
audit  such books of account  related  to such cost at any time,  on  reasonable
prior written notice, within two (2) years after the end of the calendar year in
which the Products that are the subject of such payment were  delivered for sale
in the  Territory  for the  purpose  of  verifying  the  accuracy  of such cost.
Genpharm or the Manufacturer may require such accountant to execute a reasonable
confidentiality  agreement as a condition  to providing  access to its books and
records. Subject to the final sentence of this Section 8.1, the party or parties
requesting  the audit shall bear all costs of the audit.  In the event that such
certified public accountant shall have questions which are not in their judgment
answered by such books and records,  the auditor  shall have the right to confer
with  representatives of Genpharm,  including its Chief Financial  Officer.  The
parties  agree that  information  furnished to Par and Leiner as a result of any
such audit  shall be limited to a written  statement  by such  certified  public
accountant to the effect that they have reviewed the books of account maintained
by or on behalf of Genpharm or the Manufacturer and either (a) Genpharm's or the
Manufacturer's  calculations  are  correct  or (b)  setting  forth any  required

audit. If any such audit shows any overpayment by Leiner,  Genpharm shall make a
correcting  refund or, at Leiner's option,  credit,  within thirty (30) calendar
days after  receipt  of the  written  statement  described  above  and,  if such
overpayment  shall exceed three (3%) percent of any amount payable  hereunder or
$10,000,  whichever is greater,  Genpharm shall bear all costs of the audit.  If
any such audit shows any underpayment by Leiner,  Leiner shall make a correcting
payment within thirty (30) calendar days after receipt of the written  statement
described above.

                  8.2 AUDIT OF LEINER'S  BOOKS.  Leiner shall  maintain true and
complete  books of account  containing an accurate  record of all data necessary
for proper assessment of the Net Profit payments provided in Section 6.6 hereof.
Subject to Section 8.3 hereof, Par and Genpharm shall have the right, through an
independent  certified  public  accountant  (except  any to  whom  Leiner  has a
reasonable  objection),  to audit  Leiner's  books of  account  related  to such
payment at any time, on reasonable  prior written  notice,  within two (2) years
after the end of the calendar year in which the Products that are the subject of
such  payment  were  delivered  for sale in the  Territory  for the  purpose  of
verifying  the accuracy of such payment.  Leiner may require such  accountant to
execute a  reasonable  confidentiality  agreement  as a condition  to  providing
access to its books and records.  Subject to the final  sentence of this Section
8.2,  the party or  parties  requesting  the audit  shall  bear all costs of the
audit. In the event that such certified  public  accountant shall have questions
which are not in their judgment answered by such books and records,  the auditor
shall have the right to confer with  representatives  of Leiner,  including  its
Chief Financial Officer. The parties agree that information furnished to Par and
Genpharm as a result of any such audit  shall be limited to a written  statement
by such  certified  public  accountant to the effect that they have reviewed the
books of account of Leiner and either (a) Leiner's  calculations  are correct or
(b) setting  forth any required  adjustments  thereto.  The parties  agree to be
bound  by  the  final  result  of  such  audit.  If any  such  audit  shows  any
underpayment  by Leiner,  Leiner shall make a correcting  payment  within thirty
(30) calendar days after receipt of the written  statement  described above and,
if such  underpayment  shall  exceed  three (3%)  percent of any amount  payable
hereunder or $10,000,  whichever is greater,  Leiner shall bear all costs of the
audit. If any such audit shows any overpayment by Leiner,  Genpharm shall make a
correcting payment or, at Leiner's option,  credit,  within thirty (30) calendar
days after receipt of the written statement described above.

occasion  during  any  fiscal  year and (ii)  audit the books of  account of any
fiscal year  pursuant  to this  Section 8 on more than one  occasion;  PROVIDED,
HOWEVER,  that the  limitations  provided in this Section 8.3 shall not apply to
the  Arbitrator(s)  in respect of any  resolution  of any  disputes  pursuant to
Section 12.1 hereof.

                  9. TERM AND TERMINATION.

                  9.1 TERM.  This Agreement shall commence on the Effective Date
and  continue  for a  period  of five  (5)  years  from  the  date of the  First
Commercial Sale of the Product (the "Initial  Term");  PROVIDED,  HOWEVER,  that

Initial Term or any Renewal  Term upon the  occurrence  of any of the  following
events:

                  (a) FAILURE TO OBTAIN  OVER-THE-COUNTER  PRODUCT APPROVAL.  If
the Manufacturer  shall fail to obtain Product Approval by the first anniversary
of the first  commercial  sale of the  Product in generic  form by a third party
pursuant to a valid  abbreviated new drug  application,  any party may terminate
this Agreement upon written notice thereof to the other parties.

                  (b)  CHANGE  IN  CIRCUMSTANCES.   Notwithstanding   any  other
provision  of this  Agreement,  if during any rolling  twelve  (12)-month-period
after the First  Commercial Sale of the Product,  the Net Profit for the Product

terminate  this  Agreement by notice in writing to the other  parties,  given no
later than one hundred  twenty (120) calendar days after the end of such rolling
twelve (12) month period;  PROVIDED,  HOWEVER,  a party may not  terminate  this
Agreement under this Section 9.2(b) if its own breach of this Agreement or other
actions has caused the Net Profit for such  period to be less than ******  (**%)
percent of Net Sales.

                  (c) INFRINGEMENT.  Any party may terminate this Agreement upon
ninety (90) calendar days written notice to the other parties if, based upon the
opinion of qualified  counsel,  such party  believes that there is a substantial
likelihood that the Product or API infringes the intellectual property rights of
a third party.

                  (d)  BREACH.  If any party  commits a breach or default in the
performance  or  observance  of any  of  its  material  obligations  under  this
Agreement  and such breach or default is not cured within thirty (30) days after
receipt  by such  party  of the  written  notice  from any  non-breaching  party
specifying the breach or default, then the non-breaching or non-defaulting party
may terminate this  Agreement with immediate  effect by giving written notice to
the other parties.

                  (e) BANKRUPTCY.  This Agreement shall automatically  terminate
upon  the  initiation  of  any  proceeding  in  bankruptcy,   reorganization  or
arrangement  for the  appointment of a receiver or trustee to take possession of
the assets of a party hereto or similar  proceeding under the law for release of
creditors  by or  against a party  hereto,  or if a party  hereto  shall make an
assignment for the benefit of its creditors.

                  (f) FORCE  MAJEURE  EVENT.  If, as a result of a Force Majeure
Event, a party does not perform its  obligations  hereunder for any  consecutive
period of 120 calendar  days,  any other party shall have the right to terminate
this  Agreement  in its  entirety  upon  providing  written  notice to the other
parties,  such  termination to be effective  within thirty (30) calendar days of
such notice.

                  (g)  INELIGIBLE  PERSON.  (i) In the event  that  Genpharm  or
Leiner or any Affiliate of either of them shall become an Ineligible Person with
respect to the Product,  such party shall  promptly  notify the other parties in
writing and shall keep the other parties apprised of its reasonable best efforts
to have the status as an  Ineligible  Person  removed,  and any other  party may
terminate  this  Agreement  upon thirty (30) calendar days prior written  notice
unless the status as an Ineligible  Person is removed  within such period.  (ii)
Leiner or Genpharm may terminate  this  Agreement upon thirty (30) calendar days
prior  written  notice to the other  parties if  (otherwise  than by reason of a
breach of its  obligations  hereunder) it is legally  prohibited from performing

its  obligations  hereunder  or it or one  of its  Affiliates  shall  become  an
Ineligible Person in respect of the Product (and it has made its reasonable best
efforts to remove the  prohibition  or such status as an Ineligible  Person) and
such prohibition or status as an Ineligible  Person has continued  uninterrupted
for a period of 120 calendar days.

                  9.3  POST-TERMINATION.  (a) Upon the expiration or termination
of this Agreement for any of the above  reasons,  the parties shall be permitted
to continue in their  respective  businesses  as if the  Agreement  has not been
entered into in the first place.

                  (b)  Expiration or  termination  of this  Agreement  shall not
relieve the parties of any  obligations  accruing  prior to the  effective  date
thereof or resulting  therefrom.  All payment  obligations  due pursuant to this
Agreement shall survive termination or expiration of this Agreement,  including,
without limitation, (i) the payment by Leiner for the cost of all raw materials,
production  materials and inventories  ordered on behalf of Leiner in accordance
with Sections 3.4 and 4.1 hereof, but not used by the Manufacturer, and (ii) the
payment by Leiner of all amounts pursuant to Sections 5 and 6.6 hereof.

                  10. CONFIDENTIALITY.

                  10.1 TREATMENT OF CONFIDENTIAL INFORMATION. Except as required
by applicable laws and regulations or as otherwise  provided in this Article 10,
during the Term and any Renewal  Term,  and for a period of five (5) years after
the later of the termination or expiration of this  Agreement,  each party shall
hold  in  strict  confidence,  and may not use  for  purposes  other  than  this
Agreement,  exploit or  disclose to a third party  (except as  specifically  set
forth herein or with the express prior  written  consent of the other party) any
and all Confidential Information.

                  10.2 LIMITS ON DISCLOSURE. (a) Without limiting the generality
of the foregoing,  each party may disclose  Confidential  Information,  to those
employees who need to receive the  Confidential  Information in order to further
the activities contemplated in this Agreement.  Each party shall take sufficient
precautions  to safeguard  the  Confidential  Information,  including  obtaining
appropriate commitments and enforceable  confidentiality  agreements. Each party
understands  and agrees that the  disclosure  of  Confidential  Information  may
result in serious and irreparable  damage to the other party, that the remedy at
law or any breach of this covenant may be inadequate, and that the party seeking
redress hereunder shall be entitled to injunctive  relief,  without prejudice to
any other rights and remedies to which such party may be entitled.

                  (b) It is acknowledged  that  Confidential  Information may be
obtained by a party from the other  party not only in writing or other  tangible
form (including  electronic),  but also through discussions between each party's
respective  representatives,  demonstrations,  observations and memorization and
other intangible methods.

                  (c) The above notwithstanding, each party shall have the right
with the  exercise  of  discretion,  and  insofar  as  practical  under  written
confidentiality  agreements  having  provisions  no less  stringent  than  those
contained   herein,  to  make  disclosures  of  such  portions  of  Confidential
Information  to  third  party  consultants,  attorneys,  contractors,  advisors,
Affiliates  and  governmental  agencies  where,  in the  recipient's  reasonable
judgment, such disclosure is beneficial to development, approval or marketing of
the Product pursuant to this Agreement.

                  (d) Any party shall  consult  with,  and obtain prior  written
consent of, the other  parties  before  issuing any press  release or making any
other public statement with respect to this Agreement, except as may be required
by  applicable  law  or any  listing  agreement  with  any  national  securities
exchange;  provided,  that a party  issuing  such press  release or making  such
public statement under  requirement of applicable law or listing agreement shall
nevertheless  use its best efforts to consult  with,  and obtain  prior  written
consent of, the other parties  before  issuing such press release or making such
public statement.

                  (e) Except as otherwise set forth in this Agreement,  upon the
expiration or termination  of this  Agreement and at the written  request of the
disclosing party, the receiving party shall return all Confidential  Information
of the disclosing  party (including all copies,  excerpts and summaries  thereof
contained on any media) or destroy such  Confidential  Information at the option
of the disclosing party, in either case keeping no copies or extracts thereof.

                  11. FORCE MAJEURE.

                  11.1 EFFECTS OF FORCE  MAJEURE.  No party hereto shall be held
liable or  responsible  for failure or delay in fulfilling or performing  any of
its  obligations  under  this  Agreement  (other  than the  payment  of money or
indemnification) if such failure or delay is caused by, without limitation, acts
of God,  acts  of the  public  enemy,  fire,  explosion,  flood,  drought,  war,
terrorists,  riot, sabotage, embargo, strikes or other labor disputes, or by any
other event or  circumstance  of like or different  character  to the  foregoing
beyond  the  reasonable  control  and  without  the fault or  negligence  of the
affected party, or by intervention of governmental  agency,  regardless of fault
(a "Force  Majeure  Event").  Such  excuse  shall  continue as long as the Force
Majeure Event  continues.  Subject to Section 9.2(f)  hereof,  upon cessation of
such  Force  Majeure  Event,  such  party  shall  promptly  resume   performance
hereunder.

                  11.2 NOTICE OF FORCE  MAJEURE.  Each party  agrees to give the
other  parties  prompt  written  notice of the  occurrence  of any Force Majeure
Event,  the nature  thereof and the extent to which the  affected  party will be
unable to perform its  obligations  hereunder.  Each party further agrees to use
reasonable  efforts to correct or address (if it is amenable  thereto) the Force
Majeure  Event as  quickly  as  possible  and to give the other  parties  prompt
written notice when it is again fully able to perform such obligations.

                  11.3 ALLOCATION OF CAPACITY.  If the  Manufacturer at any time
is unable to fully  supply  the  purchase  orders of Leiner  for the  Product in
accordance with this Agreement,  Genpharm shall use reasonable  efforts to cause
the  Manufacturer to equitably  allocate its available  resources and production
capacity among Leiner and its other  customers,  taking into  consideration  the
respective  requirements of each during a reasonable period of time prior to the
allocation,  as well as such expected requirements during the allocation period.
Leiner's  recourse under Section 3.5 hereof shall be Leiner's sole and exclusive
remedy (at law or equity)  against  Genpharm and Par with respect to any failure
by Genpharm  and Par to fully  supply the  purchase  orders  submitted by Leiner
pursuant to this Agreement.
