application  shall be owned by Par and submitted in its name, and Par shall have
the final  authority  with  respect to all  decisions  concerning  the  content,
compilation,  prosecution, amendment or supplementation of any such ANDA. Nortec
shall not have any obligation to carry out any analytical, stability or clinical
studies in connection  with its duty to provide  information  to Par that Nortec
has in its possession.  Nortec shall exercise  diligent efforts to assist Par in
the  review  and  compilation  of  reports  to be  included  in  any  such  ANDA
application. Nortec shall have the right to consult with Par with respect to the

       (e) Each party shall provide the other party with all  information in its
possession  or control that is necessary  for the other party to comply with any
applicable  reporting  requirements.  Each party shall promptly notify the other
party of any comments,  responses or notices  received from, or inspections  by,
the FDA or other applicable competent  authorities which relate to or may impact
a New Product. Each party shall promptly inform the other party of any responses
to such comments,  responses,  notices or inspections  and the resolution of any
issue raised by the FDA or other competent authorities.

       3.    PAR'S EXCLUSIVITY.

       (a) Commencing on the date that Par asks Nortec to begin development work
on any New Product,  Nortec shall not,  and shall cause its  Affiliates  not to,
develop,  make, have made,  sell,  offer for sale,  distribute or otherwise make
available (or contract with any third party to do any of the foregoing) that New
Product or any other  pharmaceutical  product that has the same Active Moiety as
that New Product in the Territory for its own (or such  Affiliates  own) benefit
or for  any  other  party.  The  prohibition  in the  preceding  sentence  shall
automatically  end, however,  with respect to any New Product (i) immediately if
and when Par abandons all work  involving  that New Product under this Agreement
pursuant to Section  9(b) below or (ii) one year  following  the  expiration  or
termination  of this  Agreement  with  respect to that New Product for any other
reason.  For the  avoidance of doubt,  nothing in this Section 3(a) shall in any
way limit or prohibit  Nortec or any  Affiliate  of Nortec from (1)  developing,
making,  having  made,  selling,  offering for sale,  distributing  or otherwise
making  available  (or  contracting  with  any  third  party  to do  any  of the
foregoing) any  pharmaceutical  product that competes with that New Product,  as
long as that  pharmaceutical  product does not contain the same Active Moiety as
that New Product, and (2) manufacturing,  developing,  selling,  distributing or
servicing any Non-CPS  Equipment,  or providing  technical  support for any such
equipment,  even if that equipment is utilized by any other party to manufacture
any pharmaceutical  product that is the same as that New Product or has the same
Active Moiety as that New Product.  Non-CPS  Equipment is equipment  that is not
being  provided  specifically  to a customer  for the  manufacture  of  products
embodying the CPS Technology

       (b) Within 90 days after the date of this Agreement, Par shall provide to
Nortec a written list (referred to here as the "PRIORITY  LIST") that identifies
up to twelve drugs.  Within 45 days after  receiving the Priority  List,  Nortec
will notify Par if Nortec or any of its Affiliates have  previously  granted any
option,  right or license to any third  person or entity with  respect to any of
CPS Patent Rights or Know-How  relating to the  manufacture,  use or sale within
the Territory of any drugs  identified in that Priority List; in that event, any
such drug shall be removed from the Priority List, and Par shall have the right,
within 45 days  thereafter,  to substitute a different drug for the drug that is
so removed from the Priority  List.  In the event that any third party  requests
that GAT or any Affiliate of GAT (including CPS Orocel) begin  discussions which
would  involve GAT or that  Affiliate  developing  or producing any drug that is
identified  on the Priority  List  utilizing  the CPS  Technology,  Nortec shall
promptly  notify Par of that  request.  That notice will  identify only the drug
involved;  that notice will not identify the third party. Par shall have fifteen
business  days after  receiving  that notice to provide a notice to Nortec which
sets forth a request for Nortec to begin  development  work (pursuant to Section
2(a) above) on a New Product that  utilizes  that drug.  If Par provides  such a
notice within that 15-business day period,  then Nortec shall begin  development
work on that New Product for Par  (pursuant to Section 2(a) above),  and Nortec,
GAT and their respective  Affiliates shall not perform or permit to be performed
by their  Affiliates  any  development  work or  production  of any product that
utilizes the drug for that third party or for any other  party.  If Par does not
provide such a notice within that 15-business day period, then that drug will be
automatically  and permanently be removed from the Priority List, and thereafter
Nortec, GAT and their Affiliates may conduct  development work and production of
any product  utilizing  the CPS  technology  involving  that drug for that third
party or for any other party. The restriction set forth in the fifth sentence of
this Section 3(b) shall automatically end, however,  with respect to any drug if
and when Par abandons all work under this  Agreement  involving  the New Product
that utilizes that drug.

       4.    PATENT AND KNOW-HOW LICENSE.

       (a) Subject to the terms and conditions of this Agreement,  Nortec hereby
grants to Par, and Par hereby  accepts,  a license of the CPS Patent  Rights and
the  Know-How  to make,  import,  use and sell each of the New  Products  in the
Territory.  No license is granted for any other  product  than the New  Products
that are developed by Nortec  pursuant to Section 2 above. No license is granted
for any New Product anywhere outside the Territory. Except as otherwise provided
in Sections 8 or 9 below,  this license  with  respect to any New Product  shall
remain in effect (1) with respect to any patent,  until the  expiration  of that
patent, including any reissues, extensions, continuations, continuations-in-part
or divisions of that patent,  and (2) with respect to any Know-How,  for as long
as Par is manufacturing and marketing that New Product.

       (b) Except as  provided  in the next  sentence,  the license set forth in
Section 4(a) above is  exclusive;  in other  words,  for as long as that license
remains in effect  under  Section  4(a) above with  respect to any New  Product,
Nortec  and its  Affiliates  shall not grant to any other  person or entity  any
license  to use the CPS  Patent  Rights  or the  Know-How  anywhere  within  the
Territory  for the purpose of making,  using or selling  that New Product or any
other  pharmaceutical  product that  contains the same Active Moiety as that New
Product;  provided,  however,  that nothing  herein shall prevent Nortec and its
Affiliates  from  generally  selling,  distributing  or  servicing  any  Non-CPS
Equipment,  or providing technical support for any such equipment,  even if that
equipment  is  utilized  by any other party to  manufacture  any  pharmaceutical
product  that is the same as that New Product or has the same  Active  Moiety as
that New  Product.  The  license set forth in Section  4(a) above  shall  become
non-exclusive  with  respect to any New Product if at any time after three years
from  the date of the  launch  of that New  Product,  the Net  Sales of that New
Product fall below *** of the total  generic  solid  dosage  market for the drug
that is  contained  in that New  Product;  in that event,  Nortec shall have the
right to grant to third parties non-exclusive  licenses to the CPS Patent Rights
and Know-How in the Territory  relating to that New Product under such terms and
conditions as Nortec deems appropriate.

       (c) Within 14 days after Par asks Nortec to start  development  work on a
New Product  (pursuant  to Section  2(a)  above),  Nortec will  disclose to Par,
subject to the confidentiality provisions of Section 10 below, all then-existing
Know-How  not  previously  disclosed to PAR to the extent  necessary  for Par to
describe  the  manufacture  of that New Product in  connection  with any ANDA or
equivalent document.  Thereafter, Nortec shall promptly identify and disclose to
PAR, to the extent PAR requests disclosure, any new or additional Know-How which
comes into the possession or control of Nortec or any of its  Affiliates,  again
subject to Section 10 below and to the extent  necessary for Par to describe the
manufacture  of that New  Product  in  connection  with  any ANDA or  equivalent
document.  Nortec  shall  provide to Par,  at no  additional  cost to Par,  such
assistance as Nortec deems necessary for Par to describe the manufacture of that
New Product under this Agreement.

       (d) Par hereby acknowledges that it does not have, and shall not acquire,
any interest in any  trademarks or trade names owned or licensed by Nortec,  GAT
or any of their Affiliates that may appear on the labels or packaging  materials
for any New Product.

       (e) Except as  expressly  provided in this  Section  4(e),  Par shall not
assign or sublicense  all or any portion of this Agreement or all or any portion
of the license set forth in Section 4(a) above without the prior written consent
of Nortec, which consent shall not be unreasonably  withheld.  Par may, however,
enter into one or more contracts with third parties  (referred to here as "THIRD
PARTY  CONTRACTS")  pursuant to which those third parties have the right to sell
one or more New Products,  subject to the limitations set forth in subparagraphs
(1) through (5) below, inclusive.

            If those  limitations  are satisfied with respect to any Third Party
Contract,  then Par shall have the right to sublicense the CPS Patent Rights and
the Know-How to the third party under that Third Party  Contract  solely for the
purpose of enabling  that third party to sell any New Product that is covered by
such Third Party Contract. The applicable limitations are as follows:

            (1) Any such sublicense of the CPS Patent Rights and Know-How to any
such  third  party is subject  to the prior  written  consent of Nortec for each
subject  New  Product,  which  consent  shall not be  unreasonably  withheld  or
delayed;

            (2) Prior to entering into any such Third Party Contract,  Par shall
consult  with Nortec  regarding  the  proposed  Third Party  Contract  and shall
provide Nortec with such  information as Nortec may reasonably  request relating
to that proposed Third Party Contract;

            (4) Par shall  remain fully  liable for all  obligations  under this
Agreement, notwithstanding any sublicense set forth in any Third Party Contract;
and

            (5) Par shall not,  and shall not have any right to,  sublicense  or
assign any other  rights  under this  Agreement,  including  without  limitation
providing a sublicense to develop or manufacture any products  utilizing the CPS
Patent Rights or the Know-How, sublicensing or assigning any right under Section
7(c) below to purchase  any  equipment  that  embodies  the CPS  Technology,  or
assigning  any right to utilize  any  equipment  purchased  by Par  pursuant  to
Section 7(c) below.

       5.     COMPENSATION TO NORTEC - ADVANCE PAYMENTS AND ROYALTIES.

       (a) In consideration for the services to be provided by Nortec under this
Agreement  and the license of the CPS Patent  Rights and  Know-How  set forth in
this  Agreement,  Nortec  hereby  acknowledges  that Par has paid to Nortec  the
amount of Five Hundred  Thousand Dollars  ($500,000) and Par shall  additionally
pay to Nortec  the  Advance  Payments  set forth in  Section  5(b) below and the
Royalties set forth in Section 5(c) below.

       (b) Par  shall  pay to  Nortec  payments  (referred  to here as  "ADVANCE
PAYMENTS")  totaling Two Million Five Hundred Thousand  Dollars  (US$2,500,000).
Par will pay the Advance  Payments  as follows:  $500,000 on each of October 15,
2003,  December 15, 2003, June 15, 2004,  September 15, 2004,  January 15, 2005.
[In economic terms, the Advance Payments represent advance payments of royalties
that would otherwise have been payable with respect to the New Products.]1

       (c) Par  shall  pay to Nortec a royalty  (individually  a  "ROYALTY"  and
collectively the "ROYALTIES")  with respect to each New Product based on the Net
Sales and the market share of that New Product, as shown in the following table:

- ------------------------------------------------------------------------------

                     WITH SECURITIES AND EXCHANGE COMMISSION
                         ASTERISKS DENOTE SUCH OMISSION

       For these  purposes,  the market share of each New Product shall be based
on the total sales  reported for that New Product  divided by the total sales of
the branded and generic  products in all dosage forms, as reported by IMS at the
end of each calendar year

       (d) In the  event  that Par  enters  into any  Third  Party  Contract  as
permitted   pursuant  to  Section  4(e)  above,  then  solely  for  purposes  of
calculating the Royalty applicable to sales of New Product made by a third party
under that Third Party  Contract,  Par shall pay to Nortec the Royalty  shown in
the table in Section 5(c) above,  with the "Net Sales" in that case equal to the
total  consideration  (both cash and non-cash)  received by Par under that Third
Party Contract.

       (e) Par shall pay  Royalties  to Nortec with  respect to each New Product
during such time as Par (or its  subcontractor)  offers the New Product for sale
in the  Territory  until the date that is  fifteen  (15)  years from the date of
final FDA  approval to market such New Product in the  Territory.  Par shall pay
the Royalty to Nortec with respect to each New Product  within 45 days after the
end of each  calendar  quarter  based on the Net Sales of that New Product  made
within that calendar quarter and based on Par's reasonable estimate at that time
of the  market  share  of that New  Product.  If at any time  after  making  any
quarterly  payment Par or Nortec determines that the actual market share of that
New  Product  is  different  than  the  market  share  that  was  used by Par in
determining  the amount of that payment,  Par and Nortec shall  promptly make an
appropriate  payment  to the other to  account  for that  difference.  Any other
discrepancies  in the calculation and payment of the Royalty shall be reconciled
promptly after the delivery of each quarterly  sales report  pursuant to Section
6(e) below.

       (f) While this  Agreement is in effect and for a period of six (6) months
thereafter,  Nortec  shall have the right at its expense to have an  independent
certified  public  accounting  firm  reasonably  acceptable  to Par  examine the
records described in Section 6(e) below (excluding those records,  if any, which
relate to the  qualitative  commentary of Section 6(e) below) and Section 5.2(c)
above.  Nortec may have those records examined during reasonable business hours,
not more  often  than  once each  calendar  year for  then-current  year and for
then-preceding  three (3)  years.  That  examination  shall be made for the sole
purpose of  determining  whether the amount of the Royalties has been  correctly
calculated and paid. That independent  certified public accounting firm shall be
required to treat as confidential,  and not disclose to Nortec,  any information
that it has obtained,  except such information which would properly be contained
in a sales report provided by Par to Nortec under this  Agreement.  In addition,
that  independent  certified  public  accounting  firm shall not disclose to any
other party any information obtained as a result of such examination,  except as
may be required by binding legal process or  government  requirements,  and then
only on reasonable prior notice and in consultation with Par.

       6.  ADDITIONAL OBLIGATIONS RELATING TO PRODUCT DEVELOPMENT AND MARKETING.

       The  provisions  of this  Section 6 shall apply with  respect to each New
Product  starting on the date that Par asks Nortec to start  development work on
that New Product until such time that Par abandons all work  involving  that New
Product under this Agreement.

       (a)  PROCEDURES  FOR  FILING  AN  ANDA.  (1)  Par  shall  use  reasonable
commercial  efforts to prepare,  compile and submit an ANDA for each New Product
in the Territory and, following such submission,  Par shall diligently prosecute
that ANDA with the FDA with a view to  obtaining  timely  approval  for that New
Product.


                      Product Development and Patent License Agreement - Page 11

              CONFIDENTIAL INFORMATION OMITTED AND FILED SEPARATELY
                     WITH SECURITIES AND EXCHANGE COMMISSION
                         ASTERISKS DENOTE SUCH OMISSION


       (2) At such time or times as may be reasonably  requested by Nortec,  Par
shall provide Nortec with written  reports on its efforts to obtain from the FDA
marketing approval in the Territory for that New Product,  including  supporting
documentation  reasonably  requested  by Nortec.  Nortec shall have the right to
inspect the ANDA and associated  correspondence for each New Product at any time
on prior notice during normal business hours during the term of this Agreement.

       (b) MARKETING  EFFORTS.  Par will use  reasonable  commercial  efforts to
market each New Product in the Territory  during the term of the Agreement.  Par
shall furnish and label each New Product in compliance  with the  specifications
and requirements set forth in the FDA's marketing approval documents.

       (c) ADVERSE DRUG REACTIONS. Par and Nortec shall promptly, after learning
thereof,  notify the other in writing of any report of  adverse,  or possible or
suspected adverse, effects of any New Product.  Whenever either party intends to
report the same to any governmental authority,  that party shall, when feasible,
consult  with the other party with respect to such  notification.  Specifically,
and without limiting the foregoing,  Par shall provide Nortec with adverse event
data for filing with the FDA.

       (d) MARKET REPORTS. Par and Nortec shall meet on a quarterly basis during
the  first  year  following  the  initial  launch  of  each  New  Product,  on a
semi-annual  basis  during  each of the second and third  years  following  that
initial  launch,  and on an annual  basis  during  each of the  fourth and fifth
years. At those meetings,  which will be at a location(s)  specified by Par, Par
will  report  on the  ongoing  sales  performance  of each  New  Product  in the
Territory,  including without  limitation  marketing  approaches,  promotion and
advertising  campaigns,   sales  plans  and  results,  and  performance  against
competitors. Each of Par and Nortec shall bear all of its own costs and expenses
relating to those  meetings.  At Nortec's  request,  Par shall  provide  similar
information at other times,  provided that all  information  disclosed at any of
those meetings or otherwise shall only be information  prepared or maintained by
Par in the ordinary course of its business.

       (e) NET SALES  REPORTS.  Beginning  ninety (90) days after the end of the
first  calendar  quarter in which Net Sales of each New  Product are first made,
and ninety (90) days after the end of each  subsequent  calendar  quarter during
the term of this Agreement, Par shall deliver or cause to be delivered to Nortec
a written  report showing the Net Sales of each New Product during the preceding
quarterly period.

       7.    MANUFACTURE OF NEW PRODUCTS.

       (a) For all New Products  which employ CPS  Technology Par will negotiate
in good  faith  with GAT to enter into one or more  Supply  Agreements  with GAT
pursuant to which GAT will manufacture,  at GAT's facility,  all CPS pellets for
such New Products (in other words,  pellets that are formulated or  manufactured
utilizing the CPS  Technology),  except as provided in Section 7(c) below. It is
envisioned that those Supply Agreements will, among other things,  set forth the
terms and conditions  under which Par shall purchase all of its requirements for
CPS pellets for all New Products  exclusively from GAT and GAT shall sell to Par
all of Par's  requirements  for CPS pellets for all New Products for sale in the
Territory.  It is further  envisioned that those Supply  Agreements will contain
such other  provisions with respect to  forecasting,  orders,  quality  control,
adverse event reporting, warranties and indemnities as is usual and customary in
commercial  agreements of that type.  Within the Territory,  GAT shall sell such
CPS pellets for each such New Product  exclusively  to Par.  Except as otherwise
expressly  permitted  under this  Agreement,  Par shall not  manufacture any CPS
pellets  for any New  Products  itself or  purchase  any CPS pellets for any New
Products from any other source for sale in the Territory while this Agreement is
in effect.

                     WITH SECURITIES AND EXCHANGE COMMISSION
                         ASTERISKS DENOTE SUCH OMISSION


       (b) The provisions of this Section 7(b) shall apply for  determining  the
price  that Par  will  pay to GAT for  manufacturing  CPS  pellets  for each New
Product under the Supply Agreements. On or about, but no later than the later of
(1) the date on which Par submits a New  Product  for  pivotal  bio  equivalency
studies and (2) the date on which that New Product demonstrates  stability under
accelerated  stability  conditions,  GAT will calculate and present to Par GAT's
transfer  price to supply to Par the CPS pellets for that New Product,  based on
the process used to manufacture those CPS pellets and Par's  anticipated  supply
requirements  for those CPS  pellets  as defined  and known at that time.  GAT's
transfer  price shall not be greater than the transfer  price charged by GAT for
manufacturing  similarly situated products (if any) developed or manufactured by
GAT utilizing the CPS  Technology.  That transfer  price for the CPS pellets for
that  New  Product  may  thereafter  only  be  adjusted  by GAT to  reflect  any
subsequent changes in (x) the process used to manufacture those CPS pellets, (y)
Par's supply  requirements for those CPS pellets,  or (z) inflation costs during
the period  commencing with the  establishment  of the transfer price and ending
with the time of  commercial  launch of that New Product.  In the event that Par
and GAT are not able mutually to agree on a transfer price at the time specified
in this  Section  7(b),  Par may, at its sole option,  elect to  terminate  this
Agreement  with respect to that New Product  without any further  obligation  to
Nortec or to GAT with respect to such New Product.

       (c) At any time after Par has entered into a binding Supply Agreement (or
Supply  Agreements)  with GAT to have GAT  manufacture CPS pellets for sale (not
development) for two New Products, Par shall have the right to purchase from GAT
equipment that embodies the CPS  Technology.  Par may use that equipment  solely
for the purpose of producing  CPS pellets for New  Products,  other than the New
Products that are the subject of that Supply  Agreement  (or Supply  Agreements)
and other than the products  developed  under the Two Existing  Agreements.  The
purchase  price for that equipment will be negotiated in good faith at that time
by Par and GAT. In addition to the purchase price for that  equipment,  and as a
condition to that purchase,  Par shall pay to GAT an additional  amount equal to
***% of the Net  Sales  of any New  Product  that  is  manufactured  using  that
equipment;  the calculation and payment of that amount shall be made in the same
manner  and at the same time that the  Royalty  is paid to  Nortec  pursuant  to
Section 5 above. Except as specifically provided in this Section 7(c), GAT shall
not have any obligation to sell any equipment that embodies the CPS  Technology,
either to Par or to any other  party,  that  would  allow Par to have  access to
equipment that embodies the CPS Technology.

       (d) To the extent that any part of the process used in manufacturing  any
           New  Product  for  sale  (not   development)  does  not  involve  the
           manufacture  of CPS pellets and Par decides (in its sole  discretion)
           to  contract  with any party  (referred  to here as an  "UNAFFILIATED
           PARTY") that is not an Affiliate of Par to provide such manufacturing
           services  for such New  Products  (referred  to here as the  "NON-CPS
           MANUFACTURING  SERVICES"),  then Par shall give GAT a "right of first
           refusal" to provide those Non-CPS Manufacturing Services, as follows:
           Promptly  after Par has  negotiated  with the  Unaffiliated  Party to
           provide the Non-CPS Manufacturing  Services,  Par shall send a notice
           to GAT (the "INTENT  NOTICE")  which states that Par intends to enter
           into a  contract  with  an  Unaffiliated  Party  to  provide  Non-CPS
           Manufacturing Services. The Intent Notice shall include a copy of any
           written  offer,  term sheet or proposed  contract  setting  forth the
           price  and  the  other  terms  and   conditions   of  those   Non-CPS
           Manufacturing  Services with that Unaffiliated  Party. GAT shall have
           the right in its sole discretion, to be exercised by notice (the "GAT
           NOTICE")  given to Par within  five (5)  business  days  after  GAT's
           receipt of the Intent  Notice,  to enter into a contract  with Par to
           provide those Non-CPS Manufacturing Services for Par. If GAT provides
           a GAT Notice within that 5-day period,  then Par shall not enter into
           an agreement  with the  Unaffiliated  Party to provide  those Non-CPS
           Manufacturing Services, but instead Par shall enter into an agreement
           with  GAT  pursuant  to  which  GAT  shall   provide   those  Non-CPS
           Manufacturing  Services  to Par,  at the same  price  and on the same
           terms and conditions included with the Intent Notice.

                     WITH SECURITIES AND EXCHANGE COMMISSION
                         ASTERISKS DENOTE SUCH OMISSION


           If GAT does not provide a GAT Notice within that 5-day  period,  then
           Par  shall  have  the  right  to  enter  into  a  contract  with  the
           Unaffiliated Party to provide those Non-CPS  Manufacturing  Services,
           on terms no less  favorable  to Par than  the  terms  and  conditions
           included with the Intent  Notice,  provided that such a contract with
           the  Unaffiliated  Party is signed  within 90 days of the date of the
           Intent  Notice.  If for any  reason  Par does not  enter  into such a
           contract with the Unaffiliated Party within that 90-day period,  then
           Par may not enter into such a contract with the Unaffiliated Party as
           contemplated  by the Intent Notice  without again  providing GAT with
           the "right of first  refusal"  under this section 7(d), and any other
           or future  contract for such  Non-CPS  Manufacturing  Services  shall
           again become subject to the provisions of this Section 7(d).

       (e)  Nothing  in this  Agreement  shall in any way  restrict,  or require
payments  by Par in  respect  of,  Par's  right to conduct  coating,  packaging,
labeling or other post CPS  Technology  operations  for all New  Products at any
facility (either Par's or any third party).

       8.    TERMINATION OF DEVELOPMENT RIGHTS.

       (a) Par shall have the right in its sole discretion,  as provided in this
Section 8, to terminate its right to have Nortec develop New Products under this
Agreement.  Such a  termination  by Par  is  referred  to  here  as the  "RIGHTS
TERMINATION".  Par shall have the right to exercise the Rights  Termination only
if that Rights  Termination  becomes effective on and as of October 15, 2005 and
only by providing  notice to Nortec of Par's exercise of the Rights  Termination
not later than  October 15,  2005.  Nortec  shall  provide a notice to Par,  not
earlier  than April 1, 2005 and not later than July 15, 2005,  reminding  Par of
Par's right to exercise  the Rights  Termination.  If Par does not  exercise the
Rights  Termination  by  providing  such a notice to Nortec by October 15, 2005,
then Par will not have any right to  exercise  the Rights  Termination.  If, and
only if, Par  exercises  the Rights  Termination  by providing  such a notice to
Nortec by October 15,  2005,  then the  remaining  provisions  of this Section 8
shall apply.

       (b) Par shall not have any further  right to have Nortec  develop any New
Products not previously  initiated  under this Agreement.  Without  limiting the
forgoing,  Par will not have any right to have Nortec  develop any New  Products
based  on any of the  drugs  identified  in the  Priority  List  that  have  not
previously  been initiated,  and there shall not be any  restriction  under this
Agreement on the rights of Nortec,  GAT or any of their Affiliates to develop or
produce any such drugs for any third parties.

       (c) Par,  Nortec and GAT shall  continue to develop any New  Products and
manufacture CPS pellets for any New Products that are under development prior to
the Rights Termination.  In that event,  however, in lieu of paying Royalties to
Nortec as provided in Section 5(c) above,  Par shall pay to Nortec the following
Development Fees and Modified Royalties with respect to such New Products:

           (1) Par shall pay to Nortec the following  amounts  (referred to here
       as the "DEVELOPMENT FEES") for each such New Product,  subject to Section
       8(d) below:

               (i) the sum of $125,000 for each such New Product, payable within
           ten days after the date of the Rights Termination;

                     WITH SECURITIES AND EXCHANGE COMMISSION
                         ASTERISKS DENOTE SUCH OMISSION


               (ii) the sum of  $375,000  for each such New  Product on the date
           that   Nortec   submits   to  Par  the   formulation   and   physical
           specifications  of immediate  release beads produced  during Nortec's
           first  immediate  release  core  bead  trial  campaign  for  that New
           Product.  In the event that Nortec has submitted such  specifications
           to Par with respect to any New Product on or prior to the date of the
           Rights  Termination,  then Par shall pay that  amount to Nortec  with
           respect  to that New  Product  within  ten days after the date of the
           Rights  Termination.  In the event that Nortec has not submitted such
           specifications  to Par with respect to any New Product on or prior to
           the date of the Rights Termination, then PAR may, at its sole option,
           elect  to  terminate  all  development  work  with  respect  that New
           Product;  Par can make this  election  only by  providing a notice of
           that  termination to Nortec after the date of the Rights  Termination
           and prior to the date on which Nortec submits those specifications to
           Par;

               (iii)  the sum of  $400,000  for  each  such New  Product  on the
           completion   of  both  (x)  a  successful   pivotal   biostudy   that
           demonstrates  bio  equivalence  of that New  Product  to the  branded
           sustained  release solid dosage form of the drug  containing the same
           active  ingredient(s) as that New Product,  and (y) the demonstration
           of stability of that New Product under 90-day  accelerated  stability
           conditions; and,

                (iv) the sum of $600,000 for each such New Product on the date
           of the first commercial sale of that New Product.

           (2) Par  shall  pay to Nortec a  royalty  (individually  a  "MODIFIED
       ROYALTY" and collectively the "MODIFIED  ROYALTIES") with respect to each
       such New Product  based on the Net Sales and the market share of that New
       Product,  as  shown  in the  following  table,  but  subject  to  Section
       8(c)(2)(ii) below:

- ------------------------------------------------------------------------------

           For these  purposes,  the market  share of each New  Product  will be
           determined at the end of each  calendar year from IMS published  data
           relating to total sales of such New Product,  including  both generic
           and branded  products and including all doses of such  products.  Par
           shall pay the Modified  Royalties to Nortec on the dates specified in
           Section 5(e) above. Nortec shall have the right to have the amount of
           the Modified Royalties examined as provided in Section 5(f) above.

       (d) The total amount of the Advance  Payments that Par has paid to Nortec
as of the date of the Rights Termination shall be credited against the amount of
any Development Fees that are payable pursuant to Section 8(c)(1).  If the total
amount of those  Advance  Payments  is  greater  than the total  amount of those
Development Fees, Par shall not be entitled to a refund of the excess amount.

       (e) If at any time after the Rights  Termination  Par wants Nortec or GAT
to develop or manufacture any other products utilizing the CPS Technology or the
Know-How,  neither Nortec nor GAT shall have any obligation to perform such work
for Par.  If Par wants  Nortec or GAT to develop or  manufacture  any other such
product,  at that time Par and Nortec or GAT would need to  negotiate  the terms
and conditions of that work.

       (f) After the exercise of the Rights Termination,  Par shall not have any
right thereafter to acquire any shares of stock in Nortec as contemplated by the
Stock Purchase Agreement or to otherwise share in any of Nortec's profits.

       9     TERMINATION RIGHTS.

       (a) Either Nortec or Par may terminate  this Agreement in its entirety if
the other party  (including its Affiliates)  commits a material breach of any of
the  material  terms of the  Agreement  and does not remedy that  breach  within
ninety  (90) days after  receipt of a notice  demanding  that any such breach be
remedied,  or, if ninety (90) days is an  inadequate  cure  period,  such longer
period as is reasonably necessary, provided that such breach is capable of cure,
the breaching  party promptly  commences to cure that breach,  and the breaching
party continues to act with reasonable diligence to cure that breach.

       (b) In the event that Par in good faith  determines  that it is no longer
economically  viable to pursue the  development,  registration  or sale of a New
Product in the Territory,  then Par may terminate  this  Agreement  solely as it
applies to that New Product.  In the event that Par exercises  this right,  then
Par shall use  reasonable  commercial  efforts to transfer to Nortec all rights,
contracts, data and information associated with that New Product,  including all
rights under any  unapproved or approved  ANDA. On that  termination,  Par shall
grant to Nortec,  without any cost or fee, a license to any  trademark  that Par
may have selected as a brand trademark for that New Product. Notwithstanding the
foregoing,  in any subsequent promotion of that New Product,  Nortec may utilize
in such promotion efforts previously  published  material,  for example clinical
results and  studies,  that  reference  Par's  trademark  for that New  Product.
Nortec's right to use any such trademark does not include the right to use Par's
name or any other trademark of Par.

       (c) If the  license  granted  pursuant  to Section 4 above is  terminated
pursuant to Section 9(a) above or if this  Agreement is terminated  with respect
to any  particular  New  Product  pursuant  to  Section  9(b)  above,  any  such
termination  shall be without  prejudice to Nortec's  right to receive  payments
that  are  unpaid  under  this  Agreement  as of the  date of such  termination,
including  but not limited to payment for any New Product  delivered  to Par and
any work in progress under firm purchase orders issued by Par.

       (d) If the  license  granted  pursuant  to Section 4 above is  terminated
pursuant to Section 9(a) above or if this  Agreement is terminated  with respect
to any  particular  New  Product  pursuant  to  Section  9(b)  above,  Par  will
nevertheless have the right to sell or otherwise dispose of any inventory of any
such New Product which is then on hand.

       (e) In the event that this  Agreement is  terminated  pursuant to Section
9(a)  above  by Par  for a  breach  of  this  Agreement  by  Nortec  and/or  its
Affiliates,then  (1) except as provided  in this  Section  9(e)  neither Par nor
Nortec shall have any further rights or obligations  under this  Agreement,  (2)
Par and Nortec shall remain liable to each other for all  obligations  that have
accrued prior to such  termination,  (3) Sections 3(a),  3(b), 4(a), 4(b), 5(c),
5(d), 5(e), 5(f), and 6(e) of this Agreement shall survive such termination with
respect to all New Products  for which  development  has already been  initiated
prior to such  termination,  (4)  Sections  10, 12, 13, 16, 17, 18, 19 and 20 of
this Agreement shall survive such  termination,  and (5) except Nortec shall not
have any obligation to conduct any further Development Work.

       (f) In the event that this  Agreement is  terminated  pursuant to Section
9(a) above by Nortec for a breach of this Agreement by Par, then neither Par nor
Nortec shall have any further rights or obligations under this  Agreement,EXCEPT
that Par and Nortec shall remain liable to each other for all  obligations  that
have accrued prior to such termination, and EXCEPT that Sections 10, 12, 13, 16,
17, 18, 19 and 20 of this Agreement shall survive such termination.

       (g) Par and Nortec  hereby  acknowledgethat  Par has certain  termination
rights under Sections 8(a) and 8(b) of the Stock Purchase Agreement arising from
a breach of the Stock  Purchase  Agreement and that those Sections 8(a) and 8(b)
provide that, in that event,  there will be corresponding  changes in the rights
and  obligations of Par and Nortec under this  Agreement.  Par and Nortec hereby
confirm  those  provisions  of the Stock  Purchase  Agreement to the extent that
those provisions modify this Agreement.

       (H) FOLLOWING THE FINAL CLOSING AND THE COMPLETE ACQUISITION OF NORTEC BY
PAR, PAR SHALL ACQUIRE CERTAIN RIGHTS, AND ASSUME CERTAIN OBLIGATIONS, UNDER THE
CPS  PATENT  RIGHTS  AND THE  KNOW-HOW  AS SET  FORTH IN  ARTICLE 6 OF THE STOCK
PURCHASE AGREEMENT.

       10.   CONFIDENTIALITY.

       Par and Nortec shall hold in confidence, and shall cause their respective
Affiliates  to  hold in  confidence,  all  confidential  and  other  proprietary
information of the other party  disclosed to the receiving party and relating to
this Agreement,  except for information (a) which is or becomes public knowledge
(through no fault of the receiving  party),  (b) which is made  available to the
receiving party free of an obligation of confidentiality by an independent third
party  legally  able to do so,  (c) which is already  in the  receiving  party's
possession  at the time of  receipt  from the  disclosing  party (and such prior
possession  can be  properly  demonstrated),  (d)  which is  required  by law or
regulation to be disclosed (and only to the extent of such  disclosure),  or (e)
which becomes publicly known as a result of required disclosures made to or as a
result of FDA  regulations  under which any New Product is approved  for sale in
the  Territory.  Additionally,  each  party  may  provide  such  information  to
governmental  agencies to the extent legally  required by such agencies and such
information shall not be further  disclosable  unless made public as a result of
such  disclosure  to such  agencies as required  by law. If in  connection  with
studies which are carried out to obtain FDA approval it is necessary to disclose
confidential  information  under this Agreement,  the disclosing party will make
diligent  efforts to bind the receiving party to customary  confidentiality  and
use restrictions.

       11.   REPRESENTATIONS AND WARRANTIES.

       (a) Nortec hereby  represents and warrants the following to Par as of the
date of this Agreement:

           (1) Nortec is a corporation  duly organized,  validly existing and in
good  standing  under the laws of the State of New Jersey and has the  corporate
power and  authority  and the legal  right to enter into this  Agreement  and to

corporate  action on its part to authorize  the  execution  and delivery of this
Agreement and the  performance of its  obligations  under this  Agreement.  This
Agreement  has been duly  executed and delivered by Nortec and does not conflict
with any other  obligations or contracts to which it is a party.  This Agreement

                         ASTERISKS DENOTE SUCH OMISSION


           (2) Nortec is the owner of or has  sufficient  contractual  rights to
all of the Patent Rights and Know-how licensed to Par under this Agreement,  and
Nortec has the legal power,  authority and right to grant the licenses set forth

           (3) To the best of Nortec's knowledge after reasonable investigation,
the CPS  Technology  and the Know-How do not infringe any patent  rights held by
any  third  party  in  the  Territory.   Nortec  does  not,  however,  make  any
representation  as to  whether  the CPS  Technology  and/or the  Know-How,  when
applied to  develop,  formulate,  manufacture  or sell any  particular  product,
infringes any patent rights held by any third party.

           (4) To the best of Nortec's knowledge after reasonable investigation,
Par does not require any further licenses from Nortec,  any of its Affiliates or
any third party in order to utilize the CPS  Technology  or the  Know-How in the
Territory  to  develop,  formulate,  manufacture  or sell  any New  Products  as
authorized by this Agreement.

           (5) Nortec does not have any knowledge of any claim or allegation, or
any basis of any such  claim or  allegation,  of  misuse  of any  third  party's
confidential  or  proprietary  information  with regard to use of the CPS Patent
Rights or the Know-How licensed by Nortec to Par under this Agreement.

           (6) If Par has provided to Nortec the Priority  List on or before the
execution  and  delivery  of  this  Agreement,  neither  Nortec  nor  any of its
Affiliates  have  granted any  effective  option(s) or  license(s)  to any third
person or entity under any of CPS Patent  Rights or Know-How with respect to the
manufacture,  use or sale within the  Territory of any drugs  identified  in the
Priority List.

       (b) Par hereby represents and  warrants the following to Nortec as of the
date of this Agreement:

           (1) Par is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has the corporate power and
authority  and the legal right to enter into this  Agreement  and to perform its
obligations under this Agreement.  Par has taken all necessary  corporate action
on its part to authorize the  execution  and delivery of this  Agreement and the
performance of its  obligations  under this  Agreement.  This Agreement has been
duly  executed  and  delivered  by Par and does  not  conflict  with  any  other
obligations or contracts to which it is a party.  This  Agreement  constitutes a
legal, valid and binding obligation,  enforceable against Par in accordance with
its terms.

           (2) Par will  exercise  commercially  reasonable  care  regarding the
formulation  of each New  Product,  including  but not  limited to the design of
biostudies,  the selection of qualified test facilities,  the funding and review
of final reports from the qualified test facilities  carrying out and evaluating
the  bioequivalency  of the  formulation,  the storage of the New  Product,  the
labeling of the New Product,  the packaging of the New Product,  the shipment of
the New Product, and the selection and use of trademarks on the New Product.

           (3) Prior to filing of the ANDA for any New Product,  Par will have a
study carried out at Par's expense for the purpose of  determining  if there are
any unexpired  patents in the  Territory  that would be infringed as a result of
the  manufacture,  use or sale of that New Product.  Following  the execution of
mutually   acceptable   agreements  for  each  New  Product   concerning   joint
attorney-client privilege, Par will disclose the patents obtained as a result of
such studies for each such New Product to Nortec.

                         ASTERISKS DENOTE SUCH OMISSION

       (c) Nortec does not make any representation or warranty as to whether the
manufacture, use and sale of any New Product will present any question of
infringement of any adversely held patent in the Territory solely as a result of
the use of the Know-How or the CPS Patent Rights.

       12.   INDEMNIFICATION.

       (a)  Par  shall  indemnify  and  hold  harmless  Nortec,  GAT  and  their
respective  Affiliates  and their  respective  employees,  agents,  officers and
directors from and against any costs,  claims,  judgments,  expenses  (including
reasonable attorney fees),  damages and awards (but not incidental,  indirect or
consequential damages) arising out ofa breach of its representations, warranties
or  covenants  set forth in this  Agreement,  or from Par's breach of any of the
terms and conditions of this Agreement, whether by act or omission.

       (b) Par shall defend,  indemnify and hold harmless Nortec,  GAT and their
respective  Affiliates  and their  respective  employees,  agents,  officers and
directors from and against any costs,  claims,  judgments,  expenses  (including
reasonable  attorney  fees),  damages  and awards  arising  out of any claim for
product liability relating to any New Product, regardless of the identity of the
person  or  entity  making  that  claim,  and  regardless  of how that  claim is
characterized  (including  without limitation as a negligence claim, a claim for
strict  liability,  a breach of  warranty,  a breach of any  express  or implied
contract,  or otherwise),  EXCEPT to the extent that any such damages are caused
by a breach of this Agreement by Nortec,  GAT or any such Affiliate.  While this
Agreement  is in effect,  Par shall  maintain at its expense  product  liability
coverage  covering  the  manufacture  and sale of all New  Products,  with  such
insurance  to be in the minimum  amount of  $**********,  and Par shall  provide
Nortec with, and  periodically  update upon Nortec's  request,  a certificate of
insurance evidencing that insurance.

       (c) Par shall  also  defend,  indemnify  and hold  Nortec,  GAT and their
respective  Affiliates  harmless for any loss (including  reasonable  attorneys'
fees) arising out of a claim alleging infringement of any patent, except patents
embodying the CPS  Technology  or the  Know-How,  relating in any way to the New
Products or to any of the work performed by Nortec under this Agreement.  In any
such action,  Par shall undertake the defense of such claims.  Par shall control
the defense of the action and the  prosecution  of any  relevant  counterclaims.
Notwithstanding  the  foregoing,  Par shall not settle any such  action on terms
that are  materially  prejudicial  to any  right or claim of  Nortec  in any New
Product,  in any of the CPS Patents,  or any of the Know-How without the consent
of Nortec, which consent shall not be withheld or delayed  unreasonably.  Nortec
shall  cooperate  with Par in the  defense  of such  claims,  including  without
limitation  supplying  on a timely  basis such  witnesses,  documents  and other
information  as is  necessary  to assist  Par in  fulfilling  Par's  obligations
concerning discovery in any such action.

       (d) Nortec shall  indemnify and hold harmless Par and its  Affiliates and
their respective employees,  agents, officers and directors from and against any
costs,  claims,  judgments,  expenses  (including  reasonable  attorneys  fees),
damages and awards (but not any incidental,  indirect or consequential  damages)
arising out of or a breach of its  representations,  warranties or covenants set
forth  in this  Agreement  or  from  Nortec's  breach  of any of the  terms  and
conditions of this Agreement,  whether by act or omission.  While this Agreement
is in effect,  Nortec shall  maintain at its expense a  commercially  reasonable
amount of commercial general liability  insurance coverage and shall provide Par
with,  and  periodically  provide on Par's  request,  a certificate of insurance
evidencing that insurance.

       (e) Each party shall give the other party prompt written  notice,  and in
           any event within  thirty (30) days, of any claims made which may give
           rise  to  an  indemnification   obligation  under  this  Section  12,
           including any claims asserted or made by any  governmental  authority
           having jurisdiction.

           Each party  shall  give the other  party the  opportunity  to defend,
           negotiate  and  settle  such  claims  and  will  provide   reasonable
           assistance to such other party's defense of such claim.  For any suit
           covered by a party's  indemnification  obligation  under this Section
           12, the indemnified party shall permit the indemnifying party to have
           control  of the  conduct  of the  defense  of such  suit,  including,
           without limitation, the selection of counsel.

       13.   LIMITATION ON LIABILITY.

None of Par, Nortec or their  respective  Affiliates shall have any liability to
any other party under or with  respect to this  Agreement or otherwise at law or
equity for any indirect, incidental or consequential damages, including, without
limitation,  lost  profits.  It  is  the  intention  of  the  parties  that  any
liabilities  of one  party  to  another  arising  from  performance  or  lack of
performance  under  this  Agreement  shall  be  limited  to  direct  damages  as
customarily defined.

       14.   OWNERSHIP OF INVENTIONS.

During the course of this  Agreement,  it is  contemplated  that  Nortec and Par
employees  will  cooperate in the  development  of each New  Product,  and it is
recognized that inventions and know-how may be developed which may be applicable
in the  manufacture of the New Products and other products which are not covered
by this Agreement.  For these reasons, Par shall be the sole and exclusive owner
of all inventions,  whether  patentable or  unpatentable,  arising in connection
with the parties'  performance of their  obligations  under this Agreement which
relate solely to analytical methods or to testing procedures applicable to a New
Product  and to the  particular  formulation  of each New  Product.  Nortec,  or
Affiliates of Nortec,  shall be the sole and exclusive  owner of all inventions,
whether  patentable or  unpatentable,  arising in  connection  with the parties'
performance of their  obligations  under this Agreement  which relate to the CPS
Technology  and/or the Know-How,  and all equipment that embodies any of the CPS
Technology or any Know-How, and all improvements and modifications to any of the
foregoing;  all such inventions  relating to the CPS Technology and the Know-How
shall be included in the license  granted to Par pursuant to Section 4(a) above.
Ownership of all other inventions shall be allocated  between Par and Nortec, or
Affiliates of Nortec,  in  accordance  with United States patent law and, to the
extent that they are owned by Nortec or Affiliates or Nortec,  shall be included
in the license  granted to Par pursuant to Section 4(a) above. In the event that
Par obtains any patent on any  analytical or testing  procedure  relating to any
New  Product,  Par shall grant to Nortec and GAT a royalty  free  license to the
extent  that  Nortec  and/or  GAT  uses  such  patented  subject  matter  in the
manufacture of any New Product.

       15.   STOCK OPTIONS.

       (a)  Subject  to  the   limitations   set  forth  in  this   Section  15,
Pharmaceutical  Resources,  Inc. (the parent company of Par) ("PRI") shall grant

       (b) These stock options will be covered by PRI's existing  employee stock
option plan which deals with such  matters as the annual date that such  options
are granted,  the period of time during which the options will remain in effect,
whether and under what  conditions the options will be forfeited  (other than as
specifically  set  forth  in  this  Agreement),   whether  the  options  can  be
transferred (for example, to a family member), and whether the shares into which
the options are  exercisable  will be registered  (under the  Securities  Act of
1933,  as  amended)  or,  if not,  whether  the  option  holders  will  have any
"piggyback",  "demand"  or  other  registration  rights  to  have  their  shares
registered.

       (c) The strike price (purchase price) for the shares acquired pursuant to
these stock  options  will be the market  price of those  shares on the date the
option is granted.

       (d) PRI has the right to discontinue the annual granting of stock options
at any time after Par purchases all of the shares of stock of Nortec pursuant to
the Stock Purchase  Agreement.  Such a purchase of Nortec's  shares by Par shall
not,  however,  affect any stock  options that have already been issued prior to
that time.

       (e) If and when Oliver Mueller,  Orapin Rubino or Dave Jones leaves GAT's
employment or is otherwise no longer available to work on the New Products, then
that  employee  will forfeit all stock  options which have not vested as of that
time and that  employee  will not have any right to  receive  any  future  stock
options.  (f) PRI has the right to  discontinue  the  annual  granting  of stock
options at any time after Par has terminated  the Stock  Purchase  Agreement for
any  reason.  Such a  termination  by Par shall not,  however,  affect any stock
options that have already been issued prior to that time.

       16.   PUBLICITY.

Neither  party shall  publicize  or disclose  the  existence  or terms of or the
termination  of this  Agreement,  except (1) as required by law, (2) solely with
respect to  information  relating to any New Product and the existence  (but not
the terms) of this Agreement,  when the FDA has issued an approvable  letter for
the ANDA for that New  Product,  or (3) if consented to in writing in advance of
disclosure  by an  authorized  representative  of the other party.  In addition,
neither party shall release information to the press or the public pertaining to
this  Agreement or its  performance  without first agreeing with the other party
with respect to the content of such disclosure.  Notwithstanding the above, both
parties agree that Par will release to the press a public  statement  announcing
the  agreement  of the  parties to develop  one or more oral  sustained  release
products under an exclusive  license to utilize Nortec's  intellectual  property
including  Nortec's  rights to the CPS  Technology on the effective date of this
Agreement.

       17.   FORCE MAJEURE.

No failure or omission by a party to this  Agreement in the  performance  of any
obligation of this  Agreement  shall be deemed a breach of this  Agreement,  nor
shall any such failure or omission  create any  liability,  provided  that party
uses  reasonable  efforts to resume  performance  under this  Agreement and that
party  is  capable  through  the  exercise  of such  efforts  in  resuming  such
performance,  if that failure or omission arises from any cause or causes beyond
the control of the affected party, including, but not limited to, the following,
which for purposes of the  Agreement  shall be regarded as beyond the control of
the party in question:  act of God;  acts or omissions  of any  government;  any
rules,  regulation,  or orders  issued by any  governmental  authority or by any
officer,  department,  agency or  instrumentality  hereof;  fire; storm;  flood;
earthquake; accident; war; rebellion; insurrection; riot; invasion; strikes; and
lockouts.  This Section 17, however, does not apply to any obligation to pay any
Development Fees under Section 8(c)(1) above.

       18.   ARBITRATION.

Any and all claims, disputes, controversies, and other matters arising out of or
relating  to  this  Agreement,  including  but  not  limited  to  the  formation
(including  any  claim  as to  fraud in the  inducement),  breach,  performance,
interpretation,   or  termination  Agreement,   shall  be  resolved  by  binding
arbitration in accordance with the commercial  Arbitration Rules of the American
Arbitration  Association  which  are then in  effect.  Three  arbitrators  shall
conduct the  arbitration  in the English  language in the State of New York. The
arbitrators must be knowledgeable or experienced in the pharmaceutical industry.
Each party will,  within 20 days of the date on which  arbitration is requested,
select  one  arbitrator  and  advise  the  opposite  party  of the  name of that
arbitrator, and those two arbitrators will select a third arbitrator. If the two
arbitrators  selected by the  parties are unable to agree on a third  arbitrator
within forty (40) days of the date on which arbitration is requested,  the third
arbitrator  will be  appointed  by the  American  Arbitration  Association.  The
decision  of any  two of the  three  arbitrators  will  be the  decision  of the
arbitrators.  The costs of arbitration,  including  reasonable  attorney's fees,
shall be borne by as assessed by the  Arbitrators.  Notwithstanding  anything to
the  contrary  contained in this  Section 18, the terms and  provisions  of this
Section 18 shall not  preclude any party from  seeking,  or a court of competent
jurisdiction from granting, a temporary restraining order,  temporary injunction
or  other  equitable  relief  for any  breach  of any  restrictive  covenant  or
confidentiality  covenant in this Agreement.  The arbitrators' decision shall be
reduced  to  writing  and shall be binding  on the  parties.  Judgment  upon the
award(s)  rendered  by the  arbitrators  may be  entered  in  any  court  having
applicable jurisdiction,  and execution of that award may be had in any court of
competent  jurisdiction  or application may be made to such court for a judicial
acceptance of the award and an order of enforcement.  In that  arbitration,  all
evidentiary  privileges under state and federal law,  including  attorney-client
and work-product privileges, shall be preserved and protected to the same extent
that such  privileges  would be  protected  in a United  States  district  court
proceeding  applying  the  internal  law of the  State of New York  (other  than
Section 5-1401 of the New York General  Obligations  Laws) without  reference to
the law of conflicts of any jurisdiction).  Any failure of either party to abide
by the  arbitrators'  decision  shall permit the other party to  terminate  this
Agreement in whole or in part.

       19.   NOTICES.

       Any  notice  to be given  to a party  under or in  connection  with  this
Agreement  shall be in writing and shall be delivered  by  confirmed  facsimile,

20.   MISCELLANEOUS.

       (a) ENTIRE  AGREEMENT.  This  Agreement  together with the Stock Purchase
Agreement constitutes the entire understanding and agreement between the parties
with respect to the subject  matter of this Agreement and supersedes any and all
prior  agreements,  understandings  and  arrangements,  whether oral or written,
between  the  parties  relating  to the  subject  matter of this  Agreement.  No
amendment,  change,  modification  or alteration of the terms and  conditions of
this  Agreement  shall be binding on either  party  unless it is in writing  and
signed by both parties.

       (b) INDEPENDENT  CONTRACTORS.  The parties  specifically  acknowledge the
parties are  independent  contractors  and engage in the  operation of their own
respective  businesses,  and neither  party is the agent or partner of the other
party for any purpose whatsoever.  Neither party has or shall have any authority
(either  express or implied) to enter into any  contracts or  commitments  or to
assume  any   obligations  for  the  other  party  or  make  any  warranties  or
representations on behalf of the other party.

       (c) NO ASSIGNMENT.  This  Agreement  shall not be assigned or transferred
(in whole or in part) by either  party,  except to a  wholly-owned  Affiliate of
that party,  without the prior written consent of the other party, which consent
shall not be unreasonably withheld or delayed. Par may, however, assign all (and
not less than all) of its rights in and obligations  under this Agreement to any
entity that acquires all or substantially all of the assets and business of Par,
including  without  limitation  as a result of a sale of  assets,  a merger or a
consolidation by or of Par.

       (d)  SURVIVAL.  The  representations  and  warranties  contained  in  the
Agreement, as well as all other provisions of this Agreement,  shall survive the
termination or expiration of the Agreement.

       (e) PARTIAL  INVALIDITY.  If and to the extent that any court or tribunal
of competent jurisdiction holds any of the provisions of this Agreement,  or the
application  of  any  provisions  to  any   circumstances,   to  be  invalid  or
unenforceable in a final  nonappealable  order, the parties shall use their best
efforts  to reform  the  provisions  of the  Agreement  that have been  declared
invalid in order to fully  realize,  to the extent  possible,  the intent of the
parties, and the remainder of this Agreement and the application of such invalid
provision  to  circumstances  other than those as to which it is held invalid or
unenforceable  shall  not  be  affected  thereby,  and  each  of  the  remaining
provisions  of this  Agreement  shall be valid and  enforceable  to the  fullest
extent of the law.

       (f)  LIMITATION  ON  WAIVERS.  The waiver by either of the parties of any
breach  of any  provision  of this  Agreement  by the other  party  shall not be
construed to be a waiver of any succeeding  breach of such provision or a waiver
of the provision itself.

       (g) GOVERNING LAW. This Agreement shall be governed by and construed with
the laws of the  State of New York,  without  application  of its  choice of law
principles (other than Section 5-1401 of the New York General Obligations Law) .

       (h) HEADINGS.  The headings in this Agreement  have been inserted  solely
for the convenience of reference and shall not affect the construction,  meaning
or interpretation of the Agreement or any of its terms.

       (i)  COUNTERPARTS.  This Agreement may be signed in counterparts,  all of
which together shall constitute a single contract.
