         3.2      PRODUCTION SCHEDULING.  At least thirty (30) days prior to the
start of each calendar quarter during the Supply Term, Celgene or its designated
agent shall, by written notice  hereunder,  deliver to NPI: (i) a Purchase Order
setting forth the Products to be purchased  during the next succeeding  calendar
quarter (the "Next Quarter") and the quantity in amounts at or above the minimum
order  quantities  set forth in  Schedule  3.2 hereto and the  desired  delivery
date(s)  (which  date(s)  shall be no more than once per month  during  the Next
Quarter)  for each  quantity  so  ordered;  and  (ii) a  written  forecast  (the
"Forecast") of Celgene's expected  requirements of Products and the presentation
forms thereof for the next three (3) calendar  quarters  after the Next Quarter,
together  with the expected  quantity and delivery  date(s) for each quantity so
forecast  to be ordered  during such  quarters.  NPI shall  provide  capacity to
accommodate  Product  volume  increases  in  the  Next  Quarter  and  subsequent
quarterly  forecasts of at least 25%.  Celgene may not reject as  non-conforming
orders  filled  within 10% of the requested  order  quantity,  provided that the
Products are otherwise satisfactory.

                  (a)      RELEASE FOR SHIPMENT.  NPI shall release for shipment
quantities  of Product  consistent  with each  Purchase  Order.  If there is any

Agreement, the terms of this Agreement shall control.

                  (b)      LIMITATIONS.  In no event shall NPI be  obligated  to
deliver to Celgene in the Next Quarter more than *** percent (***%) of the total
quantity set forth in the last forecast  issued by Celgene for the Next Quarter.
If the Purchase Order in the Next Quarter is more than *** percent (***%) of the
total quantity set forth in such Next Quarter forecast, NPI shall use reasonable
efforts to determine  feasibility  of meeting the  Purchase  Order  request.  If
feasible,  NPI shall produce and invoice  Celgene for any premium costs required
to deliver the product  that  exceeds  *** percent  (***%) of such Next  Quarter
forecast.  If the  Purchase  Order in the Next  Quarter is less than *** percent
(***%) of the  immediately  preceding Next Quarter  forecast,  NPI shall invoice
Celgene a carrying fee for raw materials  held in inventory  that are reasonably
allocable to such  shortfall,  in an amount equal to *** percent (***%) of NPI's
cost of such excess raw materials.

         3.3      TESTING  AND  CERTIFICATE  OF  ANALYSIS.  NPI shall  provide a
certificate of analysis ("Certificate of Analysis") to Celgene or its designated
agent with each shipment of supplied Product made hereunder. Such Certificate of
Analysis  shall  certify with respect to each  shipment and lot  (identified  by
batch/lot or control number): (i) the quantity of the shipment and (ii) that the
Product delivered was manufactured in accordance with the Specifications and the
Master Batch Records and documented according to requirements of Laws, Rules and
Regulations and applicable production standard operating procedures.

         3.4      TESTING  UPON  DELIVERY.  Promptly  following  receipt  of the
Products in any  shipment,  Celgene may check the  compliance of such batch with
the  Specifications.  Such  compliance  check shall be  performed  by  Celgene's
quality assurance and control  departments and shall be certified by the head of
such  department  (or  his/her  designee).  If Celgene  deems that any  Products
delivered  to Celgene  hereunder  fail to conform  to the  Specifications,  then
Celgene  shall  notify  NPI  thereof  in writing  (such  notice to include  test
results)  within *** days from delivery of such  Products to Celgene,  or in the
case of Products  having  Latent  Defects,  which upon diligent  examination  in
accordance  with  the  quality  control  testing  procedures  and

set out in the  Specifications  upon  receipt  could not have  been  discovered,
within *** days after Celgene's  discovery of such Latent Defect.  Celgene shall
retain the non-conforming  Products and NPI shall have the right to inspect such
Products.

                  (a)      UNDISPUTED  CLAIMS.  NPI  shall,  if it  agrees  with
Celgene's  non-conformance  assessment,  replace any such Products with an equal
quantity of Products complying with the Specifications at no cost to Celgene and
without undue delay subject to the  provisions of Section 8.3 of this  Agreement
(force  majeure).  Celgene  shall  dispose  of any  Products  which  are  not in
compliance  with the  Specifications  at NPI's cost, and in compliance  with all
applicable laws, except that, upon request,  Celgene shall follow any reasonable
instructions from NPI to return such Products to NP1 at NPI's cost.

                  (b)      DISPUTED CLAIMS. If NPI does not agree with Celgene's
non-conformance  assessment,  then NPI shall notify Celgene of such disagreement
within  *** days of  receipt  of notice of  deficiency.  If the  Parties  cannot
themselves  resolve  such  disagreement  within ***  business  days of Celgene's
receipt of NPI's  notice of  disagreement,  then the matter  shall be  submitted
(without  undue  delay) to an  independent  qualified  laboratory  agreed by the
Parties to determine whether the Products in question conform to Specifications.
The  assessment  of such  laboratory  shall be binding  upon the Parties and any
related  expense shall be borne by the Party whose analysis was in error. In the
event that NPI is the Party in error, NPI shall replace the applicable  Products
in  accordance  with Section  3.4(a)  above as if it had not disputed  Celgene's
non-conformance assessment.

         3.5      VIOLATIONS. Each Party shall notify the other of any violation
of any Laws, Rules and Regulations applicable to the Products alleged by a third
party promptly following receipt of notice of such allegation.

with all federal,  state and local laws (including  without limitation all Laws,
Rules  and  Regulations)  applicable  to  the  Manufacture  of the  Products  in
accordance with the Specifications.  NPI makes no warranties with respect to the
Products  other  than those  specifically  set forth in this  section.  No other
warranty  is   expressed   or  implied  by  NPI   including   any   warranty  of
merchantability  or fitness for a particular  purpose and none shall be implied.
Further,  all  warranties  with respect to the  Products  shall not apply to any
Product that is  subsequently  altered by the Celgene or the Carrier.  NPI shall
not be liable for  Celgene's  consequential,  incidental,  special  or  indirect
damages  resulting  from the use,  handling,  transportation,  or storage of the
Product,  even if NPI has been made aware of the  possibility  of such  damages.
Except as otherwise  set forth  herein,  the extent of NPI  liability  shall not
exceed contract value.

described herein during the Supply Term.

         6.4      NPI INSURANCE. NPI shall provide Celgene with evidence that it

agents from and against any and all third party claims, loss, damage, liability,
payment,  and  obligation,  and  all  expenses,   including  without  limitation
reasonable legal fees (collectively,  "Losses") whether such Losses are based in
contract, strict liability,  negligence,  warranty,  statutes or regulations, or
any other  legal  theory,  including  without  limitation  injury to or death of
persons  and/or  property  or  contamination  of or  adverse  effect on  humans,
animals,  aquatic  life  or  the  environment,  based  upon,  arising  out of or
otherwise in respect of: (1) the  Manufacture,  use, sale or distribution of the
Products,  provided such Products were in  compliance  with the  warranties  set
forth in the first sentence of Section 6.2, (ii) any claim threatened or brought
against NPI alleging  that the  Specifications  for any Product,  including  the
labeling for such Product,  violate any applicable United States federal, state,
or  local  rule,  regulation,   law  or  ordinance,  to  the  extent  that  such
Specifications  were provided to NPI by Celgene,  provided such Products were in
compliance  with the  warranties set forth in the first sentence of Section 6.2,
(iii) any inaccuracy in or breach of any representation,  warranty,  or covenant
made by Celgene in this Agreement;  (iv) the willful misconduct or any negligent
or reckless acts or omissions of any of Celgene's officers,  directors,  agents,
affiliates,  employees  and/or  representatives,  or any allegations of the same
made by any third  party;  (v) any  claim  threatened  or  brought  against  NPI
alleging that the Manufacture,  in accordance with the design or  Specifications
of any Product,  as provided to NPI by Celgene,  infringes upon any intellectual
property  interest of a third party,  (vi) any product warranty claim or product
liability claim  threatened or brought against NPI with respect to the Products,
provided such Products were in compliance  with the  warranties set forth in the
first  sentence of Section  6.2,  and (vii) any claim,  including  damage to any
property,   or   injury   to  any   person   (including   Celgene's   employees,
representatives,  agents,  associates,  or other  persons  invited by Celgene to
inspect NPI's  facilities  on behalf of Celgene),  arising out of, or related to
the  inspection  of  NPI's  facilities  contemplated  by  Section  2.6  of  this
Agreement,  provided that such damage or injury is not caused by the  negligence
or willful misconduct of any NPI employee,  contractor or agent or any defect in
such facilities.

         6.6      NPI  INDEMNITY.  Notwithstanding  anything to the  contrary in
this  Agreement,  NPI shall  indemnify,  defend and hold  harmless  Celgene  and
Celgene's  affiliates,  and each of their respective officers,  directors (past,
present and future) employees,  representatives  and agents from and against any
and all Losses,  based upon,  arising out of or otherwise in respect of: (i) the
failure  of  the  Products   transferred  to  Celgene   hereunder  to  meet  the
requirements  of Section 6.2 hereof,  (ii) bodily  injury or property  damage in
connection with the Manufacture of the Products;  (iii) any breach by NPI of any
representation,  warranty  or covenant  of this  Agreement;  or (iv) the willful
misconduct  or any  negligent  or  reckless  acts or  omissions  of any of NPI's
officers,  directors, agents, affiliates,  employees and/or representatives,  or
any allegations of the same made by any third party.

         6.7      JOINT NEGLIGENCE.  If any Loss incurred by or rendered against
either  Party  is  determined  by an  independent  tribunal  to be  due  to  the
negligence or willful misconduct of both NPI and Celgene, then the Parties shall
share the costs attributable to such Loss (including but not limited to the cost
of defense  thereof) in accordance with the proportion of each Party's  relative
fault,  as determined  by the  independent  tribunal.  Each Party shall give the
other notice of any Loss to which it believes the preceding sentence applies and
the Parties shall  cooperate in the defense thereof in accordance with the terms
of this Section 6.7.

         6.8      NOTICE AND  OPPORTUNITY  TO DEFEND.  Promptly  after  becoming
aware of a Loss as to which a Party is  entitled to  indemnification  under this
Agreement,  such  Party  (the  "Claiming  Party")  shall  notify  the other (the
"Indemnifying  Party") of such Loss.  The  failure  or delay in  providing  such
notice shall not relieve the Indemnifying Party of its obligations other than to
the extent it was materially  prejudiced by such failure or delay.  Upon receipt
of such notice,  the  Indemnifying  Party will handle and control the defense of
such Loss. If both Parties claim indemnification  hereunder for the same Loss or
if the Indemnifying Party in good faith rejects the claim of indemnity, then the
Claiming  Party will  handle and  control  the  defense of the Loss  against it,
pending final resolution of the Parties'  respective  claims for or with respect
to indemnity hereunder.  At the time of such resolution,  defense costs incurred
pursuant to the preceding  sentence shall be apportioned  between the Parties in
the same manner as the Parties share ultimate  liability for the underlying Loss
pursuant  to  Sections  6.5,  6.6 or 6.7  hereof.  In all  cases,  the Party not
handling and  controlling  such defense shall cooperate in such defense and may,
at its own expense,  participate in such defense  through counsel of its choice.
An Indemnifying Party shall not dispose of or agree to dispose of a Loss without
the prior written  approval of the Claiming  Party which  approval  shall not be
unreasonably withheld, conditioned or delayed.

         7.3      EFFECTS OF  TERMINATION.  Except in the event of a termination
of this  Agreement  by Celgene  pursuant to  Sections  7.2(a) or (c), if NPI has

five (5) years thereafter,  the Parties, and all of their respective  employees,
agents,  representatives,  and advisors, shall maintain in confidence all of the
other  Party's  Confidential  Information,  and shall not disclose  Confidential
Information to any third party,  or use  Confidential  Information in any way or
for the  benefit  of any  person  other  than  as  expressly  permitted  in this
Agreement.  For the  purposes  of  this  covenant,  the  Parties  shall  have no
obligation with respect to any information  which: (i) has been either published
or is otherwise in the public  domain or  subsequently  enters the public domain
without breach of the confidentiality  obligations  hereunder;  (ii) is lawfully
acquired from a third party under no obligation of confidentiality,  directly or
indirectly,  to the owner of the Confidential  Information;  or (iii) is legally
required to be disclosed pursuant to applicable law, regulation,  court order or
in  connection  with a legal  proceeding.  If either Party is required by law to
disclose  the  other's  Confidential  Information,  the  disclosing  Party  will
promptly notify the owner of the Confidential Information of the requirement and
will  cooperate in all  reasonable  respects with the owner of the  Confidential
Information to limit the amount of information to be disclosed.

         8.2      INTELLECTUAL PROPERTY.

                  (a)      NPI agrees that any and all right, title and interest
in and to any patentable and/or  copyrightable  material,  notes, data, results,
records, inventions, improvements,  developments,  discoveries and trade secrets
made,  conceived,  reduced to practice,  or  discovered  in the  Manufacture  of
Products that consists of or relates to the Products,  the use,  formulation  or
manufacture  thereof,  or any other  material,  product or process  belonging to
Celgene  or  its  licensors,   or  to  any  improvement(s),   enhancement(s)  or
refinement(s)  of any of same,  shall be the sole property of Celgene  ("Celgene
Inventions").  NPI further  agrees to assign (or cause to be assigned)  and does
hereby  assign  fully to Celgene all such  Celgene  Inventions  and any patents,
copyrights or other intellectual  property rights relating thereto. In addition,
to  the  extent  allowed  by  law,  any  Celgene   Inventions  which  constitute
copyrightable  subject matter shall be considered  "works made for hire" as that
term is defined in the United States  Copyright Act. All Celgene  Inventions and
any information  with respect thereto shall be deemed  Confidential  Information
hereunder and be subject to the confidentiality provisions of Section 8.1 above.

                  (b)      Upon  the  termination  of  this  Agreement,  or upon

                  (c)      NPI agrees to assist Celgene,  or Celgene's designee,
at  Celgene's  expense,  to obtain  and from  time to time  enforce  and  defend
Celgene's rights in the Celgene Inventions and any copyrights,  patents or other
intellectual  property rights relating thereto in any and all countries,  and to
execute all documents reasonably necessary for Celgene to do so.

                  (d)      NPI agrees that if Celgene is unable because of NPI's
unavailability,  dissolution, or for any other reason, to secure NPI's signature
to apply for or to pursue any  application  for any United  States of America or
foreign patents or copyright registrations covering the Celgene Inventions, then
NPI hereby  irrevocably  designates  and  appoints  Celgene and  Celgene's  duly
authorized officers and agents as NPI's agent and  attorney-in-fact,  to act for
and in NPI's behalf and stead to execute and file any such  applications  and to
do all other lawfully  permitted acts to further the prosecution and issuance of
patents and copyright registrations thereon with the same legal force and effect
as if executed by NPI.

                  (e)      NPI  represents  and warrants  that each employee and
independent  contractor  of NPI  has  executed  a  written  agreement  with  NPI
sufficient for NPI to fulfill its obligations to Celgene under this Section 8.2,
including,  without limitation,  an obligation on the part of each such employee
and independent contractor to assign any and all Celgene Inventions to NPI.

         8.3      FORCE MAJEURE.

                  (a)      NPI shall not be subject to any  liability  for delay
in  performance  or  nonperformance  hereunder  as a result and to the extent of
contingencies and circumstances  beyond its reasonable control  (including,  but
not limited  to,  fire,  flood,  or other  natural  catastrophe,  strike,  labor
trouble,  accident,  riot,  war, act of governmental  authority,  or act of God)
interfering with the Production, supply, transportation or receipt of Product or
with the supply of any Materials used in the Manufacture thereof.

                  (b)      Except where the nature of the event shall prevent it
from doing so, if NPI  suffers  such  force  majeure  it shall  promptly  notify
Celgene in writing after the occurrence of such force majeure and shall in every
instance,  to the extent reasonable and lawful under the circumstances,  use its
best efforts to remove or remedy such cause with all reasonable dispatch.

                  (c)      When the force majeure  conditions in question  cease
to exist,  NPI shall promptly  notify Celgene in writing about the force majeure
termination.

                  (d)      Should  a  circumstance   of  force  majeure  prevent
performance  of this  Agreement by NPI for a continuous  three (3) month period,
Celgene may  terminate  this  Agreement  upon thirty (30) days  written  notice,
provided that such notice is given during the continuance of such force majeure.

         8.4      SEVERABILITY.  If any provision of this  Agreement is found or
declared  to be  invalid  or  unenforceable  by any  court  or  other  competent
authority having  jurisdiction,  such finding or declaration will not invalidate
any other provision hereof and this Agreement shall thereafter  continue in full
force and effect, except that such invalid or unenforceable  provision,  and (if
necessary) other provisions  thereof,  shall be reformed by a court of competent
jurisdiction

forth in this  Agreement,  provided that if such court is unable or unwilling to

         8.8      WAIVER:  AMENDMENT.  Any  waiver by either  Party  hereto of a
breach or a default of any provision of this Agreement by any other Party hereto
shall not be construed as a waiver of any  succeeding  breach of the same or any
other provision, nor shall any delay or omission on the part of any Party hereto
to exercise or avail itself of any right,  power or privilege that it has or may
have hereunder operate as a waiver of any such right, power or privilege by such
Party.  Any amendment or  supplementation  of this Agreement  shall be effective
only if in writing signed by both of the Parties hereto.

         8.9      COUNTERPARTS.   This   Agreement   may  be   executed  in  two
