of SANO,  sufficient  to enable  SANO to  complete  the  Development  Program as
contemplated hereby. Except as set forth in Schedule 2.1.3, SANO has received no
notice,  and is not aware, that any portion of SANO's Technology  infringes upon
the rights of any other Person.

          2.1.4 Development Program. SANO has filed an ANDA with respect to each
of the Licensed Products and has no knowledge of any fact or circumstance  which

warrant that any Licensed  Product will be approved for commercial sale, or will
ultimately be marketed.

          2.1.5  Information.  All data and other  information  relating to SANO
and/or the Licensed Products provided by SANO, or its agents, to Par was derived

federal,  state or local regulatory agency or authority having jurisdiction with
respect to the  distribution of  pharmaceutical  products within its territorial
jurisdiction   from  selling  the  Licensed   Products  within  the  territorial
jurisdiction  of  such  government,  regulatory  agency  or  authority  (on  the
assumption  that  it  holds  whatever   licenses  are  required  for  a  foreign
corporation to carry on business  generally within such  jurisdiction)  and that
SANO is not an Ineligible  Person or Person from whom any United States federal,
state or local  government,  regulatory  authority  or  agency  which  purchases
pharmaceutical  products  (including,  without  limitation,  the federal Defense
Logistics  Agency) will or may not purchase any products  manufactured  by it or
with whom it will or may not  otherwise  conduct  business as a result its being
publicly  listed  or  otherwise  (except  for  the  fact  that  it is a  foreign
corporation).

         3.4 Supply and Use of  Information.  The parties shall,  as promptly as
possible, provide to each other any information that comes to the knowledge of a
responsible  officer of any party  relating  to any  adverse  reaction  or other

timing of said filings shall be in SANO's sole discretion.  SANO shall have full
and  complete  ownership  of all  governmental  approvals  relating  to Licensed
Products.  SANO shall  provide Par with  appropriate  sections of and a right of

Licensed Products.

         3.8 Title.  SANO will  protect  and  defend its rights to all  Licensed

                                   ARTICLE IV

                              EXCLUSIVE DISTRIBUTOR

         4.1 Subject to the provisions of this  Agreement,  SANO hereby appoints
Par as the exclusive  distributor of the Licensed Products for the United States
and Par hereby  accepts  such  appointment  and agrees to act as such  exclusive
distributor.  The rights and licenses  granted to Par under this Agreement shall
henceforth be referred to as "the Right." Par acknowledges that it has no rights
with  respect to SANO's  Technology  or the  Licensed  Products,  except for the
distribution rights with respect to the Licensed Products as herein described.

         4.2 SANO, or Par, as applicable,  covenants and agrees that, during the
term  of this  Agreement  or  until  the  Right  (or its  exclusive  nature)  is
terminated in accordance with the provisions hereof:

          4.2.1  SANO  will  refer  to Par all  inquiries  concerning  potential
purchases of Licensed Products received by it from Persons located in the United

                                       6


States or from  Persons  outside the United  States if SANO knows or  reasonably
suspects  that such Person  intends to resell or export the Licensed  Product to
the United States;

          4.2.2  SANO will  not,  directly  or  indirectly,  knowingly  sell any
Licensed  Product in the United  States nor to any Person  outside of the United
States if SANO  reasonably  expects that such Person intends to resell or export
the  Licensed  Product to the United  States and, if notified by Par that one of
SANO's  customers  is selling the Licensed  Product in the United  States in any
material respect, SANO shall either cease to supply such customer or obtain (and
enforce,  if  necessary)  an  undertaking  from  such  customer  not to sell the
Licensed Product in the United States (unless SANO is precluded from taking such
action under  applicable  law). Par  acknowledges  that SANO will use reasonable
efforts to prevent  the sale of Licensed  Products  in United  States by Persons
other than Par, but shall not be held  responsible if, despite such efforts,  it
is unsuccessful in so doing (subject to its obligations above to cease to supply
or to obtain and  enforce  the  undertaking  as and to the  extent  contemplated
above).

          4.2.3 Par shall not, and shall not authorize,  permit or suffer any of
its Affiliates to, purchase any  Transdermal  Generic Drug Delivery System which
has the same strength,  contains the same active  ingredient and is for the same
indication  as,  and  is  competitive  with,  any of the  Licensed  Products  (a
"Competitive  Product") for distribution,  sale or use in the United States from
any Person other than SANO.  Par shall not, and shall not  authorize,  permit or
suffer any of its Affiliates to, seek  regulatory  approval in the United States
for any Competitive  Product or to, directly or indirectly,  manufacture,  sell,
handle,  distribute or be financially  interested  (except as a stockholder with
not  greater  than a 5%  interest  in a  public  company)  in the  sales of such
products  within the United States for its own account or for the account of any
other Person as agent, distributor or otherwise.

          Notwithstanding  the foregoing,  if Par or PRI becomes an Affiliate of
an entity (the "Merger Partner") as a result of a merger,  acquisition, or other
similar extraordinary corporate transaction,  and such Merger Partner is engaged
in the manufacture or distribution of a Competitive Product, Par shall so notify
SANO and shall  offer (the  "Offer")  to sell,  assign and  transfer to SANO the
Right with respect to the Licensed Product with which such  Competitive  Product
is competitive  in exchange for an amount equal to the Licensed  Product Fee (as
hereinafter  defined) for such  Licensed  Product.  If,  within thirty (30) days
after its  receipt of the Offer,  SANO  accepts the Offer,  SANO  shall,  within
fifteen  (15) days of such  acceptance,  deliver  to Par,  against  delivery  of
appropriate instruments of release and transfer, its promissory note in form and
substance  reasonably  acceptable  to Par,  payable to the order of Par,  in the
principal amount of the Licensed Product Fee, bearing interest at the prime rate
of Citibank,  N.A.,  as  announced  from time to time at its offices in New York
City (the  "Prime  Rate"),  with  interest  and  principal  payable on the first
anniversary  of the date of  delivery  of such note.  From and after the date of
delivery  of such note,  Par shall have no rights with  respect to the  relevant
Licensed Product and SANO shall be free to grant any rights related thereto to a
third party or to retain such rights for itself.  If SANO declines to accept the
Offer or fails to accept the Offer  within the  aforesaid  30-day  period,  this
Agreement  shall remain in full force and effect,  except that the provisions of
this Section 4.2.3 shall not apply to that Competitive Product. Par shall notify
SANO promptly if any Merger Partner has a Competitive Product.

                                       7


          4.2.4 Par shall not, and shall not authorize,  permit or suffer any of
its Affiliates  to,  directly or  indirectly,  sell any Licensed  Product to any
Person outside of the United  States,  nor to any Person in the United States if
Par or any of its  Affiliates  reasonably  expects  that  such  Person  intends,
directly or indirectly,  to sell or export the Licensed  Product  outside of the
United  States.  If Par is  notified  by SANO  that  one of its  customers  or a
customer of Par or any of its Affiliates is exporting the Licensed  Product from
the  United  States in any  material  respect  Par  shall  (or  shall  cause its
Affiliates  to) either cease to supply such customer or obtain (and enforce,  if
necessary) an undertaking  from such customer not to sell the Product outside of
the United  States  (unless Par or any such  Affiliate is precluded  from taking
such action under applicable law). SANO acknowledges that Par will use (and will
cause its  Affiliates to use)  reasonable  efforts to prevent its customers from
exporting  any Licensed  Product out of the United  States but shall not be held
responsible if, despite such efforts, it is unsuccessful in so doing (subject to
its  obligations  above  to  cease  to  supply  or to  obtain  and  enforce  the
undertaking as and to the extent contemplated above).

          4.2.5  Par  shall  refer to SANO any  inquiry  or order  for  Licensed
Products  which Par or any of its Affiliates may receive from any Person located
outside of the United  States and from any Person  located in the United  States
where Par or any of its  Affiliates  knows or has  reason to  suspect  that such
Person intends to export the Licensed Products outside of the United States.

          4.2.6 The parties acknowledge, agree and declare that the relationship
hereby established between Par and SANO is solely that of buyer and seller, that
each is an independent contractor engaged in the operation of its own respective
business,  that neither  party shall be  considered to be the agent of the other
party for any purpose  whatsoever,  except as otherwise  expressly  indicated in
this  Agreement,  and that,  except as  otherwise  expressly  indicated  in this
Agreement,  neither party has any  authority to enter into any contract,  assume
any obligations or make any warranties or representations on behalf of the other
party.  Nothing in this Agreement  shall be construed to establish a partnership
or joint venture relationship between or among the parties.

          4.2.7 SANO shall not engage in marketing and promotion of the Licensed
Products in the United States unless reasonably requested to do so by Par.

         5.1 Par and PRI jointly and severally  represent,  warrant and covenant
as follows:

          5.1.1 Organization,  etc. They are duly organized and validly existing
under  the  laws of the  State  of New  Jersey,  have all  requisite  power  and
authority to conduct  their  business as now and as proposed to be conducted and

                                       8


to execute,  deliver and perform their  obligations  under this Agreement.  This
Agreement  has been duly  authorized,  executed and delivered by Par and PRI and
represents  a valid and binding  obligation  enforceable  against Par and PRI in
accordance with its terms.

          5.1.2 No  Conflicts;  Consents.  Execution  and  delivery  hereof,  or
performance  by either Par or PRI  hereunder,  will not (a)  violate or create a
default under (i) Par's and PRI's Certificates of Incorporation or by-laws (true
and correct  copies of which have been  delivered to SANO),  (ii) any  mortgage,
indenture, agreement, note or other instruments to which either is a party or by
which  either's  assets are  subject or (iii) any court order or decree or other
governmental  direction  or (b)  result in the  action  of any  lien,  charge or
encumbrance on any material portion of Par's and PRI's assets.

          5.1.3 Information.  All data and other information relating to Par and
PRI provided to SANO by Par and PRI, or their agents, was derived from Par's and
PRI's records (which have been diligently maintained) and is an accurate copy or
summary thereof in all material respects.

          5.1.4  Sufficiency.  Par maintains and agrees that it will continue to
maintain  those  places of  business  and  equipment  to be used in storing  and
shipping the Licensed  Products in  accordance  with Current Good  Manufacturing
Practices of the FDA and all other  applicable  requirements  of the FDA (as the
same may be  modified  from time to time).  Par hereby  further  represents  and
warrants  that it currently  has and/or has  available to it and  maintains  and
agrees to  continue  to have  and/or to have  available  to it and  maintain  an
adequate marketing  organization and qualified sales persons to promote the sale
of the Licensed Products in the United States.

         5.2 Par shall purchase the Licensed  Products from SANO as contemplated
in Article VI hereof.

         5.3 Par will  use its  reasonable  efforts  (utilizing  its  marketing,
distribution  and management  systems and those of its  Affiliates) to develop a
market for and sell the Licensed Products in the United States,  such efforts to
be not less  rigorous  than those efforts used by Par in relation to its leading
or principal  products.  Par shall devote particular  attention to the marketing
and sale of the Licensed  Products and shall use its resources in a way it deems
most effective in promoting the Licensed Products given market conditions.

         5.4 Par shall have sole  discretion  in setting the sales price for the
sale of the Licensed Products, provided that Par shall not specifically discount
the  price  of  the  Licensed  Products  for  the  benefit  of Par or any of its
Affiliates'  other products or to otherwise use the Licensed  Products as a loss
leader or incentive to procure the sale of Par's or any of its Affiliates' other
products.  Rebate and other discount  programs  (excluding any program where the
price of the  Licensed  Products  are  discounted  primarily  for the benefit of
enhancing the sale of Par's or any of its Affiliates' other products)  generally
available to Par's  customers on the purchase of  pharmaceutical  products shall
not be prohibited by this Section 5.4,  provided that such programs  shall be in
accordance with industry standards for comparable products and shall be designed
to promote the sale of the Licensed Products and not other products.

                                       9


         5.5 Par shall comply with all applicable  laws,  rules and  regulations
relating to  transporting,  storing,  advertising,  promoting and selling of the
Licensed Products within the United States and shall assume sole  responsibility
for all credit  risks and  collection  of  receivables  with respect to Licensed
Products  sold by it and its  Affiliates,  and,  except  as  expressly  provided
herein,  in respect of all dealings  between itself (and its Affiliates) and its
(and their) customers.

         5.6 Par shall notify SANO promptly  upon becoming  aware of any adverse
information  relating to the safety or  effectiveness  of a Licensed Product and
shall  consult  from time to time  with  regard to  competition  or  potentially
competitive products.

         5.7 Par hereby  further  represents  and warrants to SANO that,  to the
best  of its  knowledge,  information  and  belief,  neither  it nor  any of its
Affiliates is prohibited by any federal,  state or local law, rule or regulation
or by any order,  directive  or policy of the United  States  government  or any
state or local  government  thereof or any  federal,  state or local  regulatory
agency or authority  having  jurisdiction  with respect to the  distribution  of
pharmaceutical  products  within its territorial  jurisdiction  from selling the
Licensed  Products  within  the  territorial  jurisdiction  of such  government,
regulatory agency or authority and that neither Par nor any of its Affiliates is
a Person who, by public  notice,  is listed by a United States federal agency as
debarred,  suspended, proposed for debarment or otherwise ineligible for federal
programs in the United States (an  "Ineligible  Person") or Person from whom any

which purchases  pharmaceutical  products  (including,  without limitation,  the
federal Defense  Logistics Agency) will or may not purchase any products or with
whom it will or may not  otherwise  conduct  business  as a result of any of its
Affiliates or Par being publicly listed or otherwise.

                                   ARTICLE VI

                                    DELIVERY

         6.1 Licensed  Products  shall be made available to PRI for pickup ready
for shipment in Standard  Packaging,  or as  otherwise  permitted by the FDA, at
SANO's facilities  located in Plantation,  Florida,  or such other facilities in
the continental United States as SANO may utilize with the consent of Par, which
consent shall not be  unreasonably  withheld or delayed,  and SANO shall use its
reasonable  efforts  to  make  available  to Par  sufficient  quantities  of the
Licensed  Products to satisfy  orders for the Licensed  Products.  SANO shall be
solely  responsible  for the  contents of the labels and artwork on all finished
labeled products sold by PRI and its Affiliates. SANO shall provide all Standard
Packaging for the Licensed Products.

         6.2 To assist SANO in scheduling  production for the manufacture of the
Licensed Products,  Par shall provide to SANO,  quarterly,  a nine month rolling
forecast of its requirements for a Licensed Product. The first forecast shall be
provided by Par to SANO approximately six months prior to the anticipated market
launch of a Licensed  Product,  as  reasonably  estimated  by the  parties,  and
thereafter  shall be  provided  to SANO on or  before  the 20th day of the first

                                       10


month of each successive  quarterly period (to forecast the requirements for the
next nine  succeeding  calendar  months).  It is understood  and agreed that all
forecasts  are  estimates  only and Par  shall  only be bound  to  purchase  the
Licensed  Products  pursuant to purchase  orders  submitted  by it to SANO.  All
purchase orders shall be for minimum batch size quantities  reasonably agreed by
the  parties  and shall  anticipate  an  order/production/availability  cycle of
approximately  twelve  weeks  during the first two  contract  years (as  defined
below)  of  this  Agreement  and  an   order/production/availability   cycle  of
approximately sixteen weeks thereafter.

         6.3  Par  shall  arrange  for  shipping  and/or  transportation  of the
Licensed Products from SANO's facility to Par's Spring Valley, New York facility
and pay all shipping and related  costs.  Risk of loss and title to the Licensed
Product(s) shall pass to Par upon pick-up of the Licensed Products by, on behalf
of or for the account of Par at SANO's facility.

          6.3.1 SANO shall  promptly  notify Par by both fax and telephone  that
any order (or part thereof  acceptable  to Par) is available for pick-up at SANO
(this notice shall hereafter be referred to as the "Availability Notice").

          6.3.2 Par shall use  reasonable  and good faith efforts to pick up the
Licensed Products that are the subject of an Availability Notice within ten (10)
business  days of receipt of the  Availability  Notice;  provided  that, if such
pickup has not  occurred on or prior to the expiry of such ten day  period,  Par
shall,  for purposes of its payment  obligations to SANO pursuant to Section 7.2
below,  be deemed to have picked up the Licensed  Products which are the subject
of the Availability  Notice on the last business day of such ten-day period.  If
the Licensed Products in question have not been picked up by or on behalf of Par
within twenty (20) business days of an Availability  Notice, SANO may, but shall
not be obligated to, cause the Licensed Products to be delivered to Par's Spring
Valley,  New York,  facility by truck or other  overland  delivery at Par's sole
cost and  expense and risk of loss and title to the  Products  shall pass to Par
upon  pickup of the  Products  at SANO's  facility  in the same manner as if the
pickup had been effected by Par itself, provided that SANO shall provide for the
Licensed  Products to be insured  during  transit in a  commercially  reasonable
manner at Par's sole cost and expense.

         7.2 Price. The price to PRI for each order, or part thereof  reasonably
acceptable to PRI as contemplated in Section 8.2(d),  of Licensed  Products made
available to PRI  hereunder  shall be SANO's Costs related to such order or part
thereof.  Par shall also pay to SANO any  applicable  federal or state  sales or
excise tax payable on the  purchase of such  Licensed  Products,  which  payment
shall be remitted with the payment of the price as  contemplated  in Section 7.3
below and upon payment thereof by Par to SANO, SANO shall be solely  responsible
for remitting the amount so paid on account of such taxes to the relevant

governmental  collecting  authorities.  Promptly upon Par's request,  SANO shall
provide Par with reasonable  evidence of such direct costs and applicable  taxes
and payment of such taxes.

         7.3 Payment  Terms.  Payment for each order of Licensed  Products  made
available  by SANO for  pick-up  by Par shall be due  within 35 days of  pick-up
(whether actual or deemed pursuant to Section 6.3.2) by Par at SANO's facility.

         7.4  Additional  Licensed  Product Fee. Upon request by SANO,  Par will
remit up to an aggregate of [****] to fund skin irritation  studies  required by
the FDA for any of the Licensed Products.  Such request shall specify the amount
to be paid for the specific  Licensed Product which is the subject of such study
or  studies,  and the amount so paid by Par shall be deemed an  addition  to and
part of the Licensed Product Fee for such Licensed Product.

         7.5  Additional  Consideration.  Par shall  pay to SANO the  Additional
Consideration  described in Section 11.1 and  Schedule B hereto,  in  accordance
with the provisions of said Section 11.1.

                                  ARTICLE VIII

                               PRODUCT ACCEPTANCE

         8.1  SANO  shall  manufacture  the  Licensed  Products  and  make  them
available for pickup by Par in accordance  with all applicable  laws,  rules and
regulations including,  without limitation, the Specifications applicable to the
Licensed Product in question,  Current Good  Manufacturing  Practices of the FDA
(as the same may change from time to time) and all other applicable requirements
of the FDA and other governmental authorities having jurisdiction.

         8.2 All Licensed  Products  made  available for pick up by Par shall be
accompanied  by  quality  control  certificates  of  analysis  signed  by a duly
authorized  laboratory  official of SANO  confirming that each batch of Licensed
Product covered by such certificate meets its release  Specifications  and shall
be deemed accepted by it unless Par, acting reasonably and in good faith,  shall
give written notice of rejection (hereafter referred to as a "Rejection Notice")
to SANO within 35 days after pick up of the  Licensed  Products by, on behalf of
or for the account of Par at SANO's facility.

          (a) The Rejection Notice shall state in reasonable detail  (sufficient
to enable SANO to identify the nature of the problem and the tests or studies to
be conducted by or on its behalf to confirm or dispute  same) the reason why the
Licensed  Products are not acceptable to Par. If the Licensed  Products meet the
applicable  provisions  of  Section  8.1 and are in  quantities  specified  in a

                                       12


purchase order,  Par shall not be entitled to reject them. Any Rejection  Notice
shall be accompanied by copies of all written reports relating to tests, studies
or  investigations  performed to that date by or for Par on the Licensed Product
batch rejected.  

          (b) Upon  receipt of such  Rejection  Notice,  SANO may require Par to
return the  rejected  Licensed  Products or samples  thereof to SANO for further
testing,  in which event such Licensed Products or samples thereof,  as the case
may be,  shall be  returned  by Par to SANO or, at SANO's  direction,  at SANO's
expense.  If it  is  later  determined  by  the  parties  or  by an  independent
laboratory  or  consultant  that Par was not justified in rejecting the Licensed
Products or that Par or its Affiliates were the cause of or were responsible for
the problem,  Par shall  reimburse SANO for the costs of the return,  as well as
any other costs or expenses  incurred  by SANO as a result of the  rejection  or
return. 

          (c) Par's test  results  or basis for  rejection  shall be  conclusive
unless  SANO  notifies  Par,  within 30 days of receipt by SANO of the  rejected
Licensed Products or samples or such longer periods of time as may be reasonable
in the  circumstances to enable SANO to conduct (and receive the results of) the
appropriate  tests,  studies  or  investigations  which SANO  should  reasonably
conduct to confirm the problem in question and to identify  the source  thereof,
that it disagrees with such test results or its  responsibility  for the problem
in question.  In the event of such a notice by SANO,  representative  samples of
the batch of the Licensed  Product in question  shall be submitted to a mutually
acceptable  independent  laboratory or consultant (if not a laboratory  analysis
issue) for  analysis  or review,  the costs of which  shall be paid by the party
that is  determined  by the  independent  laboratory  or consultant to have been
responsible  for the  rejection.  

          (d) If a Licensed  Product is rejected  by Par,  Par's duty to pay the
amount payable to SANO pursuant to Section 7.2 hereof in respect of the rejected
Licensed  Product shall be suspended  until such time as it is determined (i) by
an independent  laboratory or consultant  that the Licensed  Product in question
should  not  have  been  rejected  by  Par or  (ii)  by  the  parties  or by any
arbitration  conducted  pursuant  hereto  or by a  final  order  of a  court  of
competent  jurisdiction (which is not subject to further appeal) that any act or
omission of, on behalf of or for which Par or its Affiliates is responsible  was
the cause of the problem that was the basis for the rejection. If only a portion
of an order is  rejected,  only the  duty to pay the  amount  allocable  to such
portion  shall  be  suspended.  

        8.3 In the event any Licensed Products are appropriately rejected by Par
(being Licensed  Products that do not meet the applicable  provisions of Section
8.1 other  than as a result of any act or  omission  by Par or its  Affiliates),
SANO shall replace such Licensed Products with conforming goods or, if requested
by Par, shall provide a credit to Par for the amount, if any, previously paid by
Par to SANO on account of the Licensed Products in question. The credit shall be
provided by SANO to Par  immediately  following  the expiry of the period during
which SANO may  dispute a Rejection  Notice as  contemplated  in Section  8.2(c)
above  (unless the  Rejection  Notice is  disputed by SANO,  in which event such
credit  shall  be  given  only if the  dispute  is  resolved  in  favor of Par).
Replacement  Licensed  Products,  as aforesaid,  shall be delivered to Par at no
cost to Par if Par has already paid for the rejected  Licensed  Products and not
received  a  credit  therefor,  as  aforesaid.  All  delivery  costs,  including

                                       13


insurance,  incident to the return of Licensed  Products to SANO and delivery of
the replacement  Licensed Products to Par's Spring Valley facility shall be paid
by SANO,  unless the  rejection  is  determined  not to have been  appropriately
rejected, in which case the last sentence of Section 8.2(a) shall apply. 


                                   ARTICLE IX

                             RETURNS AND ALLOWANCES

        9.1 Returns. If Par, acting reasonably and in good faith, accepts from a
customer a return of a Licensed Product and issues to such customer a credit for
the  invoice  price  thereof,  Par may debit  against  the amount of  Additional
Consideration, as hereinafter defined, due to SANO with respect to Net Sales, as
hereinafter defined, in the month in which such return occurs, any Gross Profit,
as hereinafter  defined,  previously paid, credited or due to SANO in respect of
the sale of such returned Licensed Product.

        9.2 Handling of Returns.

          (a) In the  event  any  Licensed  Product  is  returned  to Par by its
customers  because  the  Licensed  Product is alleged  to be  defective  and Par
reasonably  believes  that such  defect  is due to the fault of SANO,  Par shall
notify SANO within ten (10)  working days of any such return and provide or make
available to SANO such samples (if available) and other  information  concerning
the  returned  Licensed  Product  so as to allow SANO to test and  evaluate  the
allegedly  defective  Licensed Product.  Par shall retain a sufficient number of
samples of the allegedly  defective  Licensed Product so that additional samples
are  available  at a later date  should  additional  testing be  required  by an
independent  testing  laboratory as described in Section 9.3(b) below, or by Par
or SANO for their own  purposes.  If not enough  samples exist to be so divided,
then the parties  shall  confer and reach  agreement  as to the  handling of any
available samples.

          (b) SANO shall  complete  its review and  evaluation  of the  returned
Licensed  Product  within  twenty (20)  business  days of receiving the returned
Licensed  Product from Par or such longer period of time as may be reasonable in
the circumstances to enable SANO to conduct or cause to be conducted such tests,
studies or  investigations  (and to receive  the  results  therefrom)  as may be
required to confirm or dispute the  existence  of the problem or to identify the
cause or source thereof.

         9.3    Costs and Credits.

          (a) If  SANO  concludes  or it is  otherwise  determined  pursuant  to
Section 9.3(b) hereof that the returned Licensed Product is defective due to the
fault of SANO:

              (i) any  replacement  Licensed  Product to be  provided by SANO in
        respect of the returned  Licensed Product shall be made available to Par
        without  charge or appropriate  credit shall be given  therefor  (giving
        account to any adjustment made pursuant to Section 9.1 hereof);

                                       14


              (ii) all  delivery  costs,  including  insurance,  incident to the
        delivery of the  replacement  Licensed  Products to Par's Spring  Valley
        facility  shall  be paid by SANO or  appropriate  credit  shall be given
        therefor; and

              (iii) SANO shall provide a credit to Par for the reasonable  costs
        incurred by Par (or where the duty has been  performed by an  Affiliate,
        pursuant to the provisions of this Agreement,  for the reasonable  costs
        incurred  by  such  Affiliate)  in  respect  of the  defective  Licensed
        Product.

              (b)  If  SANO  asserts  that  the  returned  Licensed  Product  is
defective due  primarily to any act or omission of Par or its  Affiliates or any
agents or other persons acting on their behalf as aforesaid, then representative
samples of the Licensed  Products  shall be  submitted to a mutually  acceptable
independent  laboratory or consultant (if not a laboratory  analysis  issue) for
analysis or review,  the costs of which shall be paid by the party determined by
the independent laboratory or consultant to have been responsible.

              (c) If it is determined in  accordance  with Section  9.3(b) above
that any such defect is  primarily  due to any act or  omission by Par,  then no
credit or other payment of costs shall be due from SANO, and Par shall reimburse
SANO for all costs and  expenses it incurred in  connection  with the return and
investigation.

              (d) If it is determined in  accordance  with Section  9.3(b) above
that no such defect exists or, if existing,  cannot be attributable primarily to
an act or omission of either party,  then any  replacement  Licensed  Product in
respect of the returned  Licensed Product shall be made available to Par without
additional charge or appropriate credit, if any, shall be given therefor, but no
other credits or payments of costs shall be due from SANO.

           9.4  Par  acknowledges  that  the  Licensed  Products  may  be  of  a
perishable  nature and that the  Licensed  Product must be stored and shipped in
accordance with the  Specifications  applicable thereto (to the extent disclosed
in writing to Par or its Affiliates) or the conditions, if any, set forth on its
package label.

           9.5 Par agrees to notify SANO of any customer complaints with respect
to  the  quality,   nature  or  integrity  of  a  Licensed  Product  or  alleged
adverse-drug  experiences  ("ADE") within five (5) working days of their receipt
by Par and of any Par or FDA complaints within 24 hours,  except on weekends and
holidays.  SANO shall have the sole and primary  obligation to file any required
adverse  experience  report  with  FDA.  SANO  shall  also  be  responsible  for
maintaining  complaint  files as  required  by FDA  regulations.  SANO agrees to
investigate  and respond in writing to any  complaint or ADE  forwarded to it by
Par  promptly  and in no event  later than 30 days  after  receipt of the ADE or
complaint   from  Par  (or  such  longer  period  as  may  be  required  in  the
circumstances to enable SANO to conduct such tests, studies or investigations as
may be reasonably required [and to receive the results therefrom] to enable SANO
to  appropriately   respond).  SANO  shall  provide  Par  with  a  copy  of  any
correspondence,  reports,  or other  documents  relating to a  complaint  or ADE
within a reasonable period following generation of such document by SANO.

                                       15


           9.6 The provisions of this Article 9 shall survive the termination or
expiration of this Agreement.

                                    ARTICLE X

                     DAMAGES, INDEMNIFICATION AND INSURANCE

          10.1 Subject to the limitations set forth in this Article X and to the
other provisions of this Agreement, SANO, on the one hand, and Par, on the other
hand,  covenant and agree to indemnify  and save harmless the other of them from
and against  any and all  claims,  demands,  actions,  causes of action,  suits,
proceedings,  judgments,  damages,  expenses (including reasonable attorney fees
and  expenses),  losses,  fines,  penalties and other similar  assessments  (the
"Damages")  relating  to or arising  out of a breach by any such party of any of
its  representations,  warranties,  covenants or  agreements  contained  herein;
provided  that,  except  where the  breach  arises  out of a  representation  or
warranty  made by a  party  in  this  Agreement  being  intentionally  false  or
inaccurate,  or constitutes a willful  material  breach by a party of any of its
duties or  obligations  hereunder,  the claim of an aggrieved  party for Damages
arising  out of the breach  shall be limited to claiming  the  amounts  owing or
payable  to it in  accordance  with the  provisions  of this  Agreement  and any
out-of-pocket  costs and  expenses  (including  amounts paid or payable by it to
third  parties,   other  than   re-procurement   costs  [except  to  the  extent
contemplated  in Section  14.3 hereof]  which it has incurred and the  aggrieved
party shall not be entitled to recover from the  defaulting  or breaching  party
any lost profits or consequential or punitive damages,  including loss or damage
to its goodwill or reputation.  For purposes of this  Agreement  where Par is in
breach of its duties or obligations hereunder and such duties or obligations, if
delegated by Par to any of its Affiliates, could reasonably be performed by such
Affiliate  and Par has  either not  delegated  such duty or  obligation  to such
Affiliate or such Affiliate has either refused to perform or willfully  breached
such duty or obligation then Par shall be deemed to have willfully breached such
duty or  obligation  hereunder.  Similarly,  whenever in this  Agreement  Par is
required  to cause any of its  respective  Affiliates  to do or to refrain  from
doing any thing herein provided and such Affiliate refuses to do or refrain from
doing  such  thing  or  otherwise   willfully   breaches  the  provision  herein
contemplated  (on the assumption that such Affiliate were bound by the provision
herein  contemplated  as if a signatory  hereto) then Par will be deemed to have
willfully breached the provision of this Agreement in question.

           10.2 In the event that the  release  of a Licensed  Product by Par or
its Affiliates in the United States results in a third party claim:

              (a) to the extent that the Damages  awarded or incurred  relate to
or arise out of the  safety or  effectiveness  of the  Licensed  Product  or the
manufacturing,  packaging, labeling, storage or handling of the Product by SANO,
SANO shall be  responsible  therefor and shall  indemnify  and hold Par harmless
from and against all such damages; and

              (b) to the extent that the Damages  awarded or incurred  relate to
or arise out of the transportation, storage, handling or selling of the Licensed

                                       16


Product by Par or its  Affiliates,  then Par shall be  responsible  therefor and
shall indemnify and hold SANO harmless from and against all such damages.

         Upon the assertion of any third party claim against a party hereto that
may give rise to a right of  indemnification  under  this  Agreement,  the party
claiming a right to indemnification  (the "Indemnified Party") shall give prompt
notice to the party  alleged to have the duty to  indemnify  (the  "Indemnifying
Party") of the  existence  of such claim and shall give the  Indemnifying  Party
reasonable  opportunity  to control,  defend and/or settle such claim at its own
expense  and with  counsel of its own  selection;  provided,  however,  that the
Indemnified  Party shall,  at all times,  have the right fully to participate in
such  defense  at its own  expense  and with  separate  counsel  and,  provided,
further,  that both parties, to the extent they are not contractually or legally
excluded therefrom or otherwise  prejudiced in their legal position by so doing,
shall cooperate with each other and their respective insurers in relation to the
defense of such third party claims.  In the event the Indemnifying  Party elects
to defend such claim, the Indemnified Party may not settle the claim without the
prior written consent of the Indemnifying  Party. The Indemnifying Party may not
settle the claim  without the prior  written  consent of the  Indemnified  Party
unless,   as  part  of  such   settlement,   the  Indemnified   Party  shall  be
unconditionally  released  therefrom or the Indemnified Party otherwise consents
thereto in writing.  If the Indemnifying  Party shall,  within a reasonable time
after such  notice has been  given,  fail to defend,  compromise  or settle such
claim, then the Indemnified Party shall have the right to defend,  compromise or
settle such claim without prejudice to its rights of indemnification  hereunder.
Notwithstanding  the  foregoing,  in the event of any  dispute  with  respect to
indemnity hereunder,  each party shall be entitled to participate in the defense
of such claim and to join and implead the other in any such action.

         In addition to the  foregoing,  SANO will defend,  at its sole cost and
expense,  its rights with respect to the  Licensed  Products and Par's rights to
distribute the Licensed Products  hereunder against any claim,  action,  suit or
proceeding ("Action") by any third party asserting prior or superior rights with
respect to the Licensed Product,  product  infringement or similar claims (other
than  as may be  based  on acts of Par not  contemplated  herein  or  authorized
hereby) and shall  indemnify and hold Par and its  affiliates  harmless from the
cost of the defense  thereof.  Par shall, at all times,  have the right fully to
participate in such defense at its own expense.  SANO shall control such defense
and shall, in its reasonable discretion,  defend or settle such Action; provided
that,  notwithstanding the foregoing SANO shall not enter into any settlement or
compromise  of any such Action which  requires Par or any of its  Affiliates  to
make  payments  of any kind  without  the  prior  written  consent  of Par or an
unconditional  release of Par and its  Affiliates  with  respect to the  subject
matter of such Action.  The provisions of this paragraph should not be construed
as requiring SANO to bear any damages,  judgments or other  liabilities  entered
against  Par in any such  Action,  provided  that  the  foregoing  shall  not be
construed  as or deemed a waiver of any  rights Par may have  against  SANO as a
result of such Action hereunder, at law or otherwise, and all of such rights, if
any, are expressly reserved.

         10.3  Insurance.  Each of SANO and Par shall  carry  product  liability
insurance in an amount at least equal to Ten Million Dollars  ($10,000,000) with
an insurance carrier reasonably acceptable to the other party, such insurance to

                                       17


be in place at times  reasonably  acceptable to the parties,  but not later than
the date of the first  commercial sale of a Licensed  Product.  Each party shall
promptly  furnish to the other  evidence  of the  maintenance  of the  insurance
required  by this  Section  10.3  and  shall  name the  other as an  "additional
insured" under such insurance  policy.  Each party's  coverage shall (i) include
broad form  vendor  coverage  and such other  provisions  as are  typical in the
industry and (ii) name the other party as an additional insured thereunder. SANO
shall carry  clinical  testing  insurance  in an amount and at times  reasonably
acceptable to the parties.

         10.4  Survival.  The  provisions  of this  Article X shall  survive the
termination or expiration of this  Agreement,  provided that the  requirement to
maintain the insurance contemplated in Section 10.3 above shall only survive for
a period of 36 months from the effective  date of  termination  or expiration of
this Agreement.

                                   ARTICLE XI

              ADDITIONAL CONSIDERATION, REPORTING AND VERIFICATION

         11.1 Additional  Consideration.  As additional  consideration  for SANO
entering into this Agreement and permitting Par to sell the Licensed Products in
the United States in accordance with the provisions hereof, Par agrees to pay to
SANO the  additional  amounts more  particularly  described in Exhibit B to this
Agreement in respect of the  aggregate  Gross Profit (as that term is defined in
Exhibit B) of the Licensed  Products.  The amount payable to SANO  determined in
accordance  with Exhibit B is herein and in Exhibit B annexed hereto referred to
as the  "Additional  Consideration."  Par  shall  pay to SANO,  monthly,  on the
seventh  day of each  month,  commencing  on the  seventh day of the third month
after the month in which sales of the Licensed Products commence, the Additional
Consideration  payable  to SANO in  respect  of the Net  Sales  of the  Licensed
Products made by Par and its Affiliates  during the third preceding  month.  For
greater  certainty,  examples of what constitutes the "third preceding  calendar
month" are contained in Exhibit B annexed hereto.  The consideration  payable to
SANO  pursuant to this  Article XI shall be paid to it as part of the sale price
of the  Licensed  Product from SANO to Par and shall not be treated as a royalty
or similar payment.

         11.2     Reporting and Information Obligations of Par.

              (a) Approved Contracts. Par shall provide to SANO, monthly, within
seven days of the expiry of each calendar  month during the term hereof,  a copy
of each Approved Contract (as hereinafter defined), entered into by Par with its
customers during the immediately  preceding month irrespective of whether a copy
of such contract had previously been forwarded to SANO. If the Approved Contract
has a term of less than 18 months,  Par may delete  (e.g.,  by blacking out) any
information  in the  Approved  Contract  that tends to indicate  the identity or
location  of the Par  customer;  provided,  however,  that Par  marks  each such
Approved  Contract with a unique  customer code relative to the customer that is
the party to that Approved Contract.

                                       18


              (b) Net Sales and Gross Profits. Par shall report to SANO monthly,
on the 7th day of each  calendar  month during the term hereof and for 12 months
after the termination hereof:

                   (i) a sales summary, in the form annexed hereto as Exhibit C,
              showing  all sales of the  Licensed  Products  made by Par and its
              Affiliates during the immediately preceding calendar month;

                   (ii)  a  detailed  statement  showing  all  returns  and  all
              credits, rebates,  allowances and other debit and credits relevant
              to the  calculation of Net Sales and Gross Profits (as those terms
              are  defined  in  Exhibit B annexed  hereto)  for the  immediately
              preceding calendar month together with copies of all documentation
              to  support  allowable  adjustments  used in  computing  Net Sales
              during the period in question;

                   (iii) a certificate  signed by the Chief Financial Officer of
              Par certifying that, to the best of his knowledge, information and
              belief, after reasonable  investigation,  the foregoing statements
              contemplated in (i) and (ii) above are true and correct and do not
              omit any material  information required to be provided pursuant to
              this Section 11.2(b) and

                   (iv)  a  summary  of  the   calculation   of  the  Additional
              Consideration payable to SANO on such date.

         For purposes of this  Agreement a sale shall be considered to have been
         made at the time the Product(s) are shipped to the customer.

         11.3  Par  shall  make  available  for  inspection  by  SANO  at  Par's
facilities  and shall cause its  Affiliates to make  available for inspection by
SANO at their respective  facilities,  promptly  following a reasonable  request
therefor,  such additional information concerning any sales (including,  without
limitation, in respect of any sale, the date of the shipment, the code number of
the customer [or the name of the customer in the case of a customer disclosed to
SANO pursuant to Section 11.2(a) hereof and an Approved Contract], the number of
units of each Licensed Product in each dosage involved (broken down by container
size per  Product,  and the  invoice  price  charged by Par or its  Affiliates),
credits, returns, allowances and other credits and debits previously reported to
SANO  pursuant  to  Section  11.2(b)(ii)  hereof  or with  respect  to  Approved
Contracts previously reported to SANO pursuant to Section 11.2(a) hereof as SANO
may  reasonably  require from time to time (except  information  concerning  the
identity or location of a customer where Par is not already required to disclose
that  information to SANO pursuant to Section  11.2(a) hereof) to enable SANO to
confirm  or  reconcile  the  amounts  which  are or were to have been paid to it
pursuant to this  Agreement  (without the need to audit the books and records of
Par or its Affiliates pursuant to Section 11.4 hereof).

         11.4 Par shall keep and shall cause its Affiliates to keep complete and
accurate  records and books of account  containing all information  required for
  
                                       19


the  computation  and  verification of the amounts to be paid to SANO hereunder.
Par further  agrees  that at the request of SANO,  it will permit and will cause
its Affiliates to permit one or more accountants selected by SANO, except any to
whom Par or such Affiliate has some reasonable  objection,  at any time and from
time to time,  to have access during  ordinary  working hours to such records as
may be necessary  to audit,  with respect to any payment  report  period  ending
prior to such request,  the correctness of any report or payment made under this
Agreement,  or to obtain  information as to the payments due for any such period
in the case of failure of Par to report or make payment pursuant to the terms of
this  Agreement.  Such  accountant  shall not  disclose to SANO any  information
relating to the  business of PRI except that which is  reasonably  necessary  to
inform SANO of:

                   (i) the accuracy or inaccuracy of Par's reports and payments;

                   (ii) compliance or  non-compliance  by Par with the terms and
              conditions of this Agreement; and

                   (iii) the extent of any such  inaccuracy  or  non-compliance;
              provided,  that  if it is  not  reasonably  possible  to  separate
              information  relating  to the  business  of Par from that which is
              reasonably  necessary  to  so  inform  SANO,  the  accountant  may
              disclose  any  information  necessary  to so inform  SANO and SANO
              shall retain all other information disclosed as confidential.

         Par shall  provide and shall cause its  Affiliates  to provide full and
complete access to the accountant to Par's and such Affiliates'  pertinent books
and records and the  accountant  shall have the right to make and retain  copies
(including  photocopies).   Should  any  such  accountant  discover  information
indicating  inaccuracy in any of Par's payments or  non-compliance by Par or its
Affiliates  with  any of such  terms  and  conditions,  and  should  Par fail to
acknowledge  in writing to SANO the deficiency or  non-compliance  discovered by
such  accountant  within  ten (10)  business  days of being  advised  of same in
writing by the  accountant,  the  accountant  shall have the right to deliver to
SANO copies (including photocopies) of any pertinent portions of the records and
books of account which relate to or disclose the  deficiency  or  non-compliance
(to the extent not  acknowledged by Par). In the event that the accountant shall
have questions  which are not in its judgment  answered by the books and records
provided to it, the  accountant  shall have the right to confer with officers of
Par or such  Affiliate,  including  Par's or such  Affiliate's  Chief  Financial
Officer.  If any audit  under  this  Section  shall  reveal an  underpayment  or
understatement  of the amount  payable to SANO by more than  $10,000.00  for any
period in question, Par shall reimburse SANO for all costs and expenses relating
to such  investigational  audit.  SANO  shall  only have the right to audit such
books and records of Par and its  Affiliates  pursuant to this  Section  11.4 no
more often than twice in any contract year unless  earlier in such contract year
or in any of the prior  three  contract  years  such  investigation  revealed  a
discrepancy of more than $10,000.00, as aforesaid, in which case SANO shall have
the right to audit such books and records three times in such contract year. For
purposes of this  Agreement,  a contract year shall be a period of twelve months
commencing on either the date of this  Agreement or on an  anniversary  thereof.
Unless the disclosure of same is reasonably  required by SANO in connection with
any litigation or arbitration  arising out of such audit,  the accountant  shall

                                       20


not reveal to SANO the name or address (or other information  reasonably tending
to identify the location of a customer) of any customer of Par or its Affiliates
[other than one whose name has been  disclosed to SANO  pursuant to Section 11.2
hereof], but shall identify such customer to SANO, if necessary, by the customer
code number used by Par in its  reporting  obligations  to SANO [and Par and its
Affiliates shall make such information  known to the accountant].  Par may, as a
condition to providing any accountant  access to its books and records (or those
of its  Affiliates),  require  SANO  to  execute  a  reasonable  confidentiality
agreement consistent with the terms of this Section 11.4.

         11.5 Except as specifically set forth to the contrary,  all payments to
be made under this Agreement  shall bear interest equal to two percent above the
prime rate as quoted by Citibank N.A., New York, New York,  calculated daily (as
at the close of business on each such day) and compounded monthly,  from the day
following  the day the  payment  is due until the date on which it is paid.  Any
adjustment  to the prime rate as quoted by Citibank N.A. from time to time shall
result in a corresponding  adjustment to the rate of interest payable hereunder,
the rate of interest  quoted by  Citibank  N.A. at the close of business on each
day to be the rate applicable for such day.

         11.6 The obligation of Par to make the payments contemplated in Section
11.1 and to provide the reports and  information  contemplated  in Sections 11.2
and 11.3 and the right of SANO to conduct its audits or investigations  pursuant
to Section 11.4 hereof  shall  survive the  termination  or  expiration  of this
Agreement and shall apply to all Licensed Products made available to Par by SANO
prior to the effective  date of the  termination or expiration of this Agreement
(or made  available  to Par after such date  pursuant to any  provision  of this
Agreement)  notwithstanding  that such Licensed Products may have been resold by
Par or its  Affiliates to its or their  customers  after the  effective  date of
termination or expiration.  For greater certainty,  the parties  acknowledge and
agree  that  it  is  their  intention  that  Par  pay  to  SANO  the  Additional
Consideration  applicable to Net Sales of all Licensed Products supplied by SANO
to Par  pursuant  to this  Agreement  (in  respect of which the  purchase  price
charged  by SANO to Par  therefor  [whether  paid or owing]  was  determined  in
accordance with the provisions of Section 7.2 hereof or was provided to Par free
of such charge pursuant to any other  provision of this Agreement)  irrespective
of whether such Licensed  Product is resold by Par or its Affiliates prior to or
subsequent to the effective  date of termination or expiration of this Agreement
and that SANO's  rights  pursuant to Section  11.4 hereof  shall  continue for a
period of twelve  (12)  months  following  the final  sale of all such  Licensed
Products.

         11.7 Par shall have the right,  upon reasonable  advance written notice
to SANO, to inspect SANO's  facilities at which the Licensed  Products are being
manufactured to monitor compliance by SANO with FDA Good Manufacturing Practices
and to otherwise  confirm that the Licensed  Products are being  manufactured in
accordance with their respective Specifications.  Similarly, SANO shall have the
right, upon reasonable advance written notice to Par to inspect those facilities
of Par and any of its  Affiliates  which are used in the  storage  of any of the
Licensed  Products to ensure  compliance by Par or such  Affiliate with FDA Good
Manufacturing  Practices and to otherwise  ensure that the Licensed  Products do
not cease to meet their  Specifications  as a result of any  storage or shipping
conducted by Par or its  Affiliates.  SANO shall cooperate with Par in providing
access to its facilities and Par shall  cooperate and shall cause its Affiliates

                                       21


to  cooperate  in providing  access to SANO to its  facilities  and those of its
Affiliates used as aforesaid.

         11.8 SANO shall keep complete and accurate records and books of account
containing all  information  required for the  computation  and  verification of
SANO's Costs as  contemplated in Section 7.2 hereof with respect to the Licensed
Product(s)  made available to Par by SANO pursuant  hereto.  SANO further agrees
that at the  request of Par it will permit one or more  accountants  selected by
Par except any to whom SANO has some reasonable objection, to have access during
ordinary  working  hours to such books and records as may be  necessary to audit
the amounts  previously  charged by SANO to Par  pursuant to Section 7.2 hereof.
Such  accountant  shall not  disclose  to Par any  information  relating  to the
business of SANO except the accuracy or inaccuracy of SANO's previously reported
charges  and the  amount,  if  any,  that  Par  may  have  been  overcharged  or
undercharged  with respect to Licensed Products made available to it. Should any
such accountant  discover  information  indicating that Par has been overcharged
for  Products  made  available  to it, and should  SANO fail to  acknowledge  in
writing to Par the  inaccuracy  discovered  by such  accountant  within ten (10)
business  days of  being  advised  of same in  writing  by the  accountant,  the
accountant   shall  have  the  right  to  make  and  retain  copies   (including
photocopies) of any pertinent portions of the records and books of account which
relate to or disclose the inaccuracy (to the extent not  acknowledged  by SANO).
SANO  shall  provide  full and  complete  access  to the  accountant  to  SANO's
pertinent  books  and  records.  In the event  that the  accountant  shall  have
questions which are not in its judgment answered by such books and records,  the
accountant  shall  have the right to confer  with  officers  of SANO,  including
SANO's Chief Financial Officer.  If any audit under this Section shall reveal an
overstatement  of the  amount  payable to SANO by more than  $10,000.00  for the
Licensed  Products  in  question,  SANO  shall  reimburse  Par for all costs and
expenses relating to such investigation/audit.  It is understood and agreed that
Par shall only have the right to audit such books ad records of SANO pursuant to
this Section 11.8 no more often than twice in any contract  year unless  earlier
in  such  contract  year  or in any of  the  prior  three  contract  years  such
investigation revealed a discrepancy of more than $10,000.00,  as aforesaid,  in
which case Par shall have the right to audit such books and records  three times
in such contract year.  Unless the disclosure of same is reasonably  required by
Par in connection with any litigation or arbitration  arising out of such audit,
the accountant shall not reveal to Par the name or address (or other information
reasonably  tending to identify  the  location of a supplier) of any supplier of
materials to SANO in the  manufacturing  or  packaging of the Licensed  Products
(but shall identify such supplier to Par if necessary,  by a code name or number
supplied by such accountant) or the name of or financial information relating to
any  employee of SANO.  SANO may, as a condition  to  providing  any  accountant
access  to  its  books and   records,   require  Par  to  execute  a  reasonable
confidentiality  agreement  consistent  with the terms of this Section 11.8. The
rights of Par  pursuant to this Section 11.8 shall  survive the  termination  or
expiration of this Agreement for a period of one year.

                                       22


                                   ARTICLE XII

                             RIGHT OF FIRST REFUSAL

         12.1 Right of First Refusal. During the term hereof, Par shall have the
right of first  refusal to  distribute  the  Licensed  Products  in the State of
Israel,  on a  product  by  product  basis,  in  accordance  with the  following
procedures.

         12.2  Procedures.  For each Licensed Product with respect to which SANO
proposes to enter into a  distribution  agreement  in Israel with a third party,
SANO shall  communicate to Par in writing a reasonably  detailed  description of
the provisions of such agreement (a "Proposed Israeli Distribution  Agreement").
Within 30 days of its receipt of a Proposed Israeli Distribution  Agreement (the
"Acceptance  Period"),  Par shall notify SANO whether it wishes to enter into an
agreement  with SANO on such terms.  If Par notifies SANO within the  Acceptance
Period  that it wishes to do so,  Par and SANO will  enter  into a  distribution
agreement  on such terms.  If Par fails to notify SANO of its  election to enter
into such an  agreement  within  the  Acceptance  Period,  SANO may enter into a
license or distribution  agreement with respect to such Licensed  Product with a
third party on substantially the same terms as set forth in the Proposed Israeli
Distribution  Agreement and Par's rights under this Article XII will  terminate.
SANO  may  not  enter  into  such  an  agreement  with a third  party  on  terms
substantially  different from those set forth in the relevant  Proposed  Israeli
Distribution  Agreement without first offering such terms to Par for a period of
thirty  days.  If SANO shall not enter into the  Proposed  Israeli  Distribution
Agreement  within 30 days following the  expiration of the Acceptance  Period or
any extension thereof as set forth in the preceding  sentence,  SANO's execution
of any such Agreement or any other Proposed Israeli Distribution Agreement shall
again be subject to Par's rights under this Article XII. Each  Proposed  Israeli
Distribution  Agreement  for each  Licensed  Product  shall be  subject to Par's
rights of first  refusal in  accordance  with the  procedures  set forth in this
Section 12.2.

                                  ARTICLE XIII

                              TERMS AND TERMINATION

         13.1 This Agreement shall become effective on the date hereof and shall
remain in effect for a period of ten years per Licensed  Product starting on the
date such Licensed Product becomes available for sale in commercial  quantities,
unless earlier  terminated in accordance  with the provisions of this Agreement.
Thereafter,  this Agreement shall  automatically  be renewed as to each Licensed
Product from year to year unless either party gives notice of termination to the
other  party at least one  hundred  and  twenty  days prior to the expiry of the
initial term or of any renewal term.

         13.2  Either  party  may,  by notice  in  writing  to the other  party,
terminate  this  Agreement  if such other party shall have  breached  any of its
material duties or obligations  under this Agreement (other than the obligations
of Par to pay to SANO any amount due to SANO  hereunder  [whether  on account of

                                       23


Additional  Consideration,  the price for the Licensed Products or otherwise] or
to provide SANO with the reports or information  contemplated in Section 11.2 or
11.3 hereof) and such breach shall remain  uncured for at least sixty days after
the aggrieved party shall have given notice of the breach to the other party.

         13.3 SANO may, by notice in writing to Par, terminate this Agreement if
Par fails to pay to SANO any amount payable by Par to SANO hereunder, whether on
account of the  Additional  Consideration,  the purchase  price for the Licensed
Products,  interest or otherwise, as and when the same shall have become due and
payable or Par shall have failed to deliver (or caused to be  delivered,  as the
case may be), in timely  fashion,  the reports or  information  contemplated  in
Section  11.2 or 11.3  hereof,  and in  either  case,  such  breach  shall  have
continued  unremedied for a period of twelve  business days after written notice
of such breach has been given by SANO to Par;  provided  that Par shall not have
the right to such twelve-day  grace period within which to cure such default and
SANO shall have the  immediate  right to terminate the Agreement for such breach
if Par shall have previously  breached  Section 11.2 or 11.3, or failed to remit
any sums of at least $10,000.00 to SANO, when due, in the aggregate, one time in
the twelve month period immediately preceding the default in question.

         13.4 Either  party may  terminate  this  Agreement on thirty days prior
written  notice to the other  party if such party or the other  party is legally
prohibited from performing its obligations  hereunder (other than by reason of a
breach of its  obligations  hereunder)  or becomes  (or, in the case of Par, its
Affiliate  becomes) an  Ineligible  Person (and,  where the party  purporting to
terminate the Agreement is also the party  prohibited  from  performing or it or
its Affiliate is the Ineligible  Person,  it [or its Affiliate,  as the case may
be] has made diligent good faith best efforts to remove the  prohibition  or its
status as an Ineligible  Person) and such prohibition or status as an Ineligible
Person shall have continued uninterrupted for a period of 120 days.

         13.5  Either  party  may  terminate  this  Agreement  in  respect  of a
particular Licensed Product (the "Specific  Product"),  but this Agreement shall
continue  in respect of any other  Licensed  Product,  on thirty (30) days prior
written notice to the other party (which notice must be delivered within 90 days
of the expiration of the applicable contract year) if the aggregate Net Sales of
the Specific  Product made by PRI and its Affiliates  for any complete  contract
year after the second  anniversary of the date on which such  Specified  Product
became available for sale shall be less than the amounts stated in or determined
pursuant to Section 13.8; provided, however, SANO may not terminate with respect
to any Specific Product pursuant to this Section 13.5 without the consent of Par
in the event that SANO shall have previously  terminated the exclusive nature of
the Right pursuant to Section 13.8 and shall be selling, directly or indirectly,
such Licensed Product in the United States.

         13.6 Either party may terminate this  Agreement in accordance  with the
provisions of Section 15.1 hereof.

         13.7 Par or SANO shall have the right to terminate  this Agreement upon
written  notice to the other in the event that any one or more of the  following
events shall become  applicable to such other party  (herein  referred to as the
"Party"):

                                       24


              (a) an order is made or a resolution or other action of such Party
is taken for the dissolution,  liquidation,  winding up or other  termination of
its corporate existence;

              (b) the  Party  commits a  voluntary  act of  bankruptcy,  becomes
insolvent,  makes an assignment  for the benefit of its creditors or proposes to
its creditors a reorganization,  arrangement, composition or readjustment of its
debts or obligations or otherwise proposes to take advantage of or shelter under
any statute in force in the United States for the protection of debtors;

              (c) if any  proceeding  is taken with respect to a  compromise  or
arrangement,  or to have such  Party  declared  bankrupt  or to have a  receiver
appointed in respect of such Party or a substantial  portion of its property and
such  proceeding  is instituted by such Party or is not opposed by such Party or
if such  proceeding is instituted by a Person other than such Party,  such Party
does not proceed diligently and in good faith to have such proceeding  withdrawn
forthwith;

              (d) a receiver  or a receiver  and manager of any of the assets of
such Party is appointed and such receiver or receiver and manager is not removed
within ninety days of such appointment;

              (e) such  Party  ceases  or  takes  steps to cease to carry on its
business.

SANO shall  similarly  have the right to terminate  this  Agreement upon written
notice to PRI if any of the foregoing events becomes applicable to any Affiliate
of PRI that has been expressly assigned obligations under this Agreement.

        13.8  (a) If

                   (i) in the  twenty-four  (24) month period (such period being
              herein  referred to as the "A Period")  beginning on the date (the
              "A  Commencement  Date") the first of any  shipments  of  Licensed
              Product "A" is made available to Par hereunder,  the aggregate Net
              Sales of  Licensed  Product "A" for such A Period is less than the
              Product Sales Threshold (as hereinafter defined);

                   (ii) in the twenty-four  (24) month period (such period being
              herein  referred to as the "B Period")  beginning on the date (the
              "B  Commencement  Date") the first of any  shipments  of  Licensed
              Product "B" is made available to Par hereunder,  the aggregate Net
              Sales of  Licensed  Product "B" for such B Period is less than the
              Product Sales Threshold; or

                   (iii) in any twelve month period commencing on the second and
              each  subsequent  anniversary of the A Commencement  Date or the B
              Commencement  Date the Net Sales of the relevant  Licensed Product
              sold by Par and its  Affiliates  in such  period  is less than the
              Product Sales Threshold;

and the  shortfall  in sales  cannot be  attributable  primarily to the fault of
SANO,  SANO  shall  have the right to  convert  Par's  Right  hereunder  from an
exclusive to a non-exclusive right to

                                       25


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

distribute  such Licensed  Product upon ninety days prior written notice to Par.
As used herein,  as to any Licensed  Product,  the Product Sales Threshold shall
mean an amount  reasonably  agreed upon by Par and SANO after  consideration  of
relevant market factors and conditions, provided that if Par and SANO shall fail
or be unable to agree as to any Licensed Product for any period in question, the
Product Sales Threshold for such period and Licensed Product shall be [****].

              (b)  Notwithstanding the exercise by SANO of its right pursuant to
Section 13.8(a) hereof,  and the resultant  conversion of Par to a non-exclusive
distributor hereunder, Par shall have the right to sell the Licensed Products on
a non-exclusive basis on the terms and conditions as set forth herein, except as
provided otherwise in this Paragraph 13.8, during the balance of the term of the
Agreement  (subject to earlier  termination  as herein  provided) and SANO shall
continue  to  supply  the  Licensed  Products  to Par  in  accordance  with  the
provisions  hereof,  provided that the  obligation of SANO to use its reasonable
best efforts to supply Par with its requirements of the Licensed  Products shall
take into account Par's requirements as well as the requirements of SANO and any
other third party  distributor  or  distributors  appointed  by SANO to sell the
Licensed Products in the United States.

              (c) In the event  that SANO  exercises  its rights  under  Section
13.8(a) and  contemporaneously  therewith or subsequent  thereto  enters into an
agreement  with any Person  (herein  referred to as a "Third  Party  Licensee"),
authorizing  or licensing  such Third Party Licensee to sell any of the Licensed
Products in the United  States on royalty,  payment or other cash  equivalent or
otherwise readily economically  measured terms more favorable to the Third Party
Licensee (such more favorable terms being herein referred to as the "MFP") then:

                   (i) SANO  shall  promptly  notify Par of such  agreement  and
              shall  describe  in the notice  both the MFP and any  obligations,
              duties,  undertakings or other consideration to be provided by the
              Third Party Licensee; and

                   (ii) Par shall have  thirty  days from the date of receipt of
              such notice to notify SANO whether Par desires to have the benefit
              of the MFP,  which can be accepted only if Par shall agree (to the
              extent not already  assumed in this  Agreement) to any  additional
              obligations,   duties,   or  undertakings,   and  to  provide  any
              consideration to be provided by the Third Party Licensee.

Par's  entitlement to seek the benefit of the MFP shall be conditioned  upon and
subject to Par assuming and being capable of fully  performing  all the non-cash
obligations  assumed by the Third Party  Licensee in a manner  substantially  as
valuable to SANO.  If Par shall  dispute  such  assessment,  Par shall so notify
SANO,  whereupon  the issue shall be deemed to be a dispute  between the parties
and subject to resolution pursuant to Section 15.2 hereof.

                                       26



         13.9  Notwithstanding  the  termination or expiration of this Agreement
pursuant to this Article  XIII or any other  provision  of this  Agreement,  all
rights  and  obligations  which  were  incurred  or which  matured  prior to the
effective  date of  termination  or  expiration,  including  accrued  Additional
Consideration  and any cause of action for  breach of  contract,  shall  survive
termination  and be subject to  enforcement  under the terms of this  Agreement.
Termination of this Agreement  shall not affect any duty of Par or SANO existing
prior to the effective  date of  termination or expiration and which is, whether
or not by expressed terms, intended to survive termination. Without limiting the
generality  of the  foregoing,  termination  shall not  affect  any duty to keep
confidential  any Confidential  Information  (within the meaning of Section 14.4
hereof)  disclosed by one party to the other (or its Affiliate) as  contemplated
in Section 14.4 hereof,  but rather such Confidential  Information shall be held
by the receiving  party subject to such  restrictions  on use and  disclosure as
provided in the said Section.

         13.10 Upon  termination  of this  Agreement  by Par pursuant to Section
13.2 or 13.7 or  pursuant  to Section  13.4 as a result of SANO's  inability  to
perform  its  obligations  hereunder  or becoming  an  Ineligible  Person or the
termination  of this  Agreement by SANO  pursuant to Section  13.5 hereof,  SANO
shall,  at the request of Par,  repurchase  all  Licensed  Products  then in the
possession, custody or control of Par and available for sale (and which have not
been  adulterated  since  they were made  available  for pick up by Par) and all
packaging  material  in the  possession,  custody  or  control of Par which were
specifically  acquired by Par for these  Licensed  Products  and which cannot be
used by Par or its Affiliates for any other products sold by any of them, at the
price originally paid by Par therefor plus all  transportation  costs previously
incurred  (even if not yet paid) by Par  payable in cash on  delivery  by Par to
SANO.  SANO shall pay all  transportation  costs  associated  with  shipping the
repurchased Licensed Product to SANO or to such other places SANO may require.

         13.11 In the event that this  Agreement is  terminated  pursuant to the
provisions of Section 13.4 hereof as a result of a party (herein  referred to as
the  "Prohibited  Party") being unable to perform its  obligations  hereunder as
therein  contemplated  or having  become  (or its  Affiliate  having  become) an
Ineligible  Person  and  within  twelve  (12)  months of the  effective  date of
termination of this Agreement the Prohibited  Party is again able to perform its
obligations  hereunder  or has ceased  (or its  Affiliate  has  ceased) to be an
Ineligible Person, then the Prohibited Party shall, by notice in writing, advise
the other party  (herein  referred to as the  "Receiving  Party")  that it is no
longer legally  prohibited from performing its duties and obligations  hereunder
or that it has ceased (or that its  Affiliate  has  ceased) to be an  Ineligible
Person and the Receiving  Party shall have the right,  to be exercised by notice
in writing given to the  Prohibited  Party within thirty (30) days of receipt of
the  aforesaid  notice from  Prohibited  Party,  to  reinstate  this  Agreement;
provided,  however, that if the Prohibited Party is Par then SANO shall have the
right to reinstate  this Agreement as if a proper notice had been given pursuant
to Section 13.8 of this Agreement and Par shall be reinstated on a non-exclusive
basis,  but only to the extent  that such  reinstatement  will not  violate  the
provisions of any  agreement  SANO shall have entered into during the period Par
was a Prohibited Party.



                                       27



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

         13.12 If SANO terminates this Agreement  pursuant to Section 13.2, 13.3
and 13.7 hereof then Par shall not and shall cause its  Affiliates not to, for a
period of twelve (12) months  following the effective date of termination,  sell
in the United States any Competitive Product.

         13.13 In the event that SANO  terminates this Agreement in respect of a
Specific Product pursuant to Section 13.5 hereof,  SANO shall, at the request of
Par,  make  available  to Par  within  a  reasonable  period  of  time  of  such
termination,  such number of units of such Specific Product as shall be equal to
the net number of units of such  Specific  Product sold by Par during the entire
contract  year  immediately  preceding  the year in which this  Agreement  is so
terminated or such lesser  number of units of each such Specific  Product as Par
shall advise SANO in writing within ten business days of such termination.  Such
Specific  Product  shall  be  made  available  to Par  in  accordance  with  the
provisions of this Agreement and the provisions of this Agreement shall apply to
all such Specific  Product as if such Specific Product had been supplied by SANO
during the term of this Agreement.

              (a) If SANO has not  received an approval of an ANDA for  Licensed
Product B prior to the later of [****] for Par may terminate this Agreement with
respect to Licensed  Product B by  providing  SANO with  written  notice of such
termination  and neither party shall have any obligation  hereunder with respect
to Licensed Product B other than applicable  confidentiality  provisions and the
payment  by SANO  described  in the  following  sentence.  In the  event of such
termination,  SANO shall pay Par the sum of (i) [****] and (ii) the amount  paid
by Par in respect of Licensed  Product B pursuant  to Section  7.4 hereof,  with
half of such sum payable three (3) months after SANO's receipt of notice of such
termination  and half of such sum  payable  fifteen  (15)  months  after  SANO's
receipt of notice of such termination.

              (b) For the  purposes of this  Section  13.14,  the dates on which
ANDAs were filed for the respective  Licensed  Products shall be as set forth on
Exhibit A attached hereto.

                                   ARTICLE XIV

               RECALLS, ADMINISTRATIVE MATTERS AND CONFIDENTIALITY

         14.1  Recalls.  In the event  that it  becomes  necessary  to conduct a
recall, market withdrawal or field correction  (hereafter  collectively referred
to as "recall") of any Licensed Product  manufactured by SANO and sold by Par or
its Affiliates the following provisions shall govern such a recall:

                                       28


              (a)  After  consulting  with  SANO,  and on terms  and  conditions
reasonably  satisfactory  to SANO,  Par  shall  conduct  (and  shall  cause  its
Affiliate to conduct) the recall and shall have primary responsibility therefore
and SANO and Par shall each  cooperate  with the other in recalling any affected
Licensed  Product(s).  Par  covenants  and agrees to  maintain  and to cause its
Affiliates to maintain  such records of all sales of the Licensed  Products made
by  Par or  its  Affiliates  as are  required  by the  FDA or as are  reasonably
appropriate  for a distributor of  pharmaceutical  products to maintain so as to
enable a recall to be properly completed.

              (b)  Irrespective  of whether the recall is initiated by Par or by
SANO:

                   (i) If it is  later  demonstrated  that  the  reason  for the
              recall  was due  primarily  to acts or  omissions  of SANO (or the
              safety or efficacy of the Licensed  Product other than as a result
              of acts or  omissions of Par or its  Affiliates),  then SANO shall
              pay or  reimburse,  as the  case  may be,  all  reasonable  direct
              out-of-pocket  expenses,  including  but not limited to reasonable
              attorney's  fees and  expenses  and  credits  and recall  expenses
              claimed  by and  paid  to  customers,  incurred  by Par or SANO in
              connection with performing any such recall, provided that expenses
              incurred  by  Par  shall  be in  accordance  with  the  terms  and
              conditions of the recall approved by SANO; or

                   (ii) If it is later determined that the reason for the recall
              was  due  primarily  to  the  acts  or  omissions  of  Par  or its
              Affiliates,  then Par shall pay or reimburse,  as the case may be,
              all direct  out-of-pocket  expenses,  including but not limited to
              reasonable  attorney's  fees and  expenses  and credits and recall
              expenses claimed by and paid to customers, incurred by Par or SANO
              in connection with performing any such recall; or

                   (iii) If the  parties  are  unable to agree that the cause of
              the recall was due  primarily to the act or omission of one of the
              parties (or its Affiliates,  as the case may be) within sixty days
              of the initiation of the recall and have not commenced arbitration
              proceedings  to resolve such dispute  within such sixty day period
              then all  direct  out-of-pocket  costs  incurred  by Par and SANO,
              including  but not  limited  to  reasonable  attorney's  fees  and
              expenses  and credits and recall  expenses  claimed by and paid to
              customers,  shall be shared by the parties in  proportion to their
              sharing  of Gross  Profits in  respect  of the  Licensed  Products
              recalled.

Each of the  parties  shall use its  reasonable  best  efforts to  minimize  the
expenses of recall which it incurs.  It is understood and agreed that the direct
out-of-pocket  costs and expenses of the recall  contemplated in Paragraphs (i),
(ii) and (iii) above shall not include the invoice  price  charged by PRI or its
Affiliates  to the customers  for the Products  recalled,  which amount shall be
dealt with in accordance  with the provisions of Section 9 hereof and shall also
not include any excess  re-procurement  costs  (within the meaning of  Paragraph
14.3 hereof) and related penalties and assessments,  which costs,  penalties and
assessments  shall be an  expense  of Par  except  to the  extent  that it is an
expense  of SANO  pursuant  to  Section  14.3  hereof  (provided  that where the
provisions of Paragraph (iii) above apply,  the excess  reprocurement  costs and

                                       29


related penalties and assessments  incurred  pursuant to Approved  Contracts [as
that term is defined in Section 14.3  hereof]  shall be shared by the parties in
the  proportion  in which Gross  Profits  are shared in respect of the  recalled
Products sold pursuant to such Approved Contracts).

              (c) All Licensed  Products  recalled pursuant to this Section 14.1
shall be treated as Licensed  Products  returned to Par by its customers and the
provisions of Section 9 shall apply thereto.

              (d) The  party  initiating  the  recall  shall  inform  FDA of the
proposed recall;  however,  nothing contained herein shall preclude either party
from  informing  FDA of any proposed or actual recall by either party should the
recalling  party  fail to inform  FDA of that  recall  within ten (10) days of a
written request by the non-recalling party to so inform FDA.

              (e) For greater certainty, in the event of a recall, neither party
or its Affiliates shall profit from any out-of-pocket expenses incurred by it in
connection  with the recall and for which it is  reimbursed  by the other  party
and,  except where the recall  relates  directly to an  intentional  breach of a
representation or warranty contained in this Agreement or arises directly out of
a  willful  material  breach  by a party  of any of its  duties  or  obligations
hereunder (in each case, as contemplated in Section 10.1 hereof),  neither party
shall have a claim  against the other party for any damages,  losses or expenses
which it suffers or incurs as a result thereof except to the extent permitted or
contemplated in this Section 14.

              (f) Each party shall provide  reasonable  evidence to the other of
the  out-of-pocket  expenses being claimed by it and the rights of SANO pursuant
to Section  11.4 and the rights of Par  pursuant  to  Section  11.8 shall  apply
thereto.

         14.2 ANDA-Related FDA Correspondence. Each of the parties shall provide
the other with a copy of any  correspondence  or notices  received by such party
from FDA relating or referring to the Licensed  Product(s)  within ten (10) days
of receipt. Each party shall also provide the other with copies of any responses
to any such  correspondence  or  notices  within  ten (10)  days of  making  the
response.

         14.3     Excess Re-procurement Costs.

              (a)  In  the  event  that  a  recall   occurs   which  recall  was
necessitated  primarily  by any act or omission of SANO and SANO does not supply
Par with replacement Licensed Product on a timely basis or if SANO, in breach of
its  obligations  under  this  Agreement,  fails  to  make  Licensed  Product(s)
available to Par, SANO shall,  in addition to any  reimbursement  required under
Section 14.1, pay any excess  re-procurement  costs and/or related  penalties or
assessments incurred by, or assessed on, Par by a customer of Par pursuant to an
Approved  Contract  (as that term is defined  below) due to Par's  inability  to
supply Licensed Product(s) to such customer due to the aforesaid acts, omissions
or breaches of SANO.

              (b) SANO  shall  cooperate  with Par with  respect to any legal or
administrative  proceedings  that arise pursuant to the Approved  Contracts as a


                                       30


result of Par's inability to supply Licensed  Product(s) to such customer due to
the  aforesaid  acts,  omissions  or breaches by SANO.  The  foregoing  shall be
without  prejudice  to any other  damages,  expense  or costs  that Par may have
suffered in connection with SANO's  inability to supply the Licensed  Product as
aforesaid,  subject to the  limitations  and other  provisions set forth in this
Agreement.

                  (c) For purposes  hereof the term  "Approved  Contract"  shall
mean a contract  entered into by Par on or after the Execution  Date with one of
its customers:

                   (i) pursuant to which Par agrees to supply such customer with
              pharmaceutical  products  which include the Licensed  Products (or
              any of them),  and which provides that if Par fails to supply such
              customer with the Licensed  Product in accordance  with  specified
              terms and  conditions  therein set forth then such customer  shall
              have the right to procure a comparable replacement product for the
              Licensed  Product in substitution  for the Licensed  Products that
              Par has failed to supply to such customer in  accordance  with the
              provisions  of its  agreement  and to charge back to Par any costs
              and expenses  incurred by such customer to acquire such comparable
              replacement  product in excess of the price which was to have been
              charged by Par to the customer for the Licensed  Products which it
              failed to provide (such excess costs and expenses being the excess
              re-procurement  costs  contemplated  in  Section  14.1 and in this
              Section 14.3);

                   (ii) which has a term of twelve (12) months or less; and

                   (iii) which provides for the supply of the relevant  Licensed
              Product in an amount not greater  than the amount  forecast by Par
              pursuant  to Section 6.2  hereof,  taking  into  account all other
              sales of the Licensed Product in the relevant period; or

                   (iv) where the contract has a term of more than 12 months, or
              provides for an amount greater than that contemplated by Paragraph
              (iii) above, SANO has approved or has been deemed to have approved
              such contract in accordance with the provisions of Section 14.3(v)
              hereof; or

                   (v) if the approval of SANO as contemplated in Paragraph (iv)
              above is requested, Par shall have provided to SANO, in accordance
              with the  provisions  of this  paragraph,  a complete  copy of the
              proposed  final  agreement  between Par and its customer  prior to
              entering into such contract. A copy of any contract to be provided
              to SANO as  contemplated  in this Paragraph (v) shall be forwarded
              to SANO in the manner  contemplated  in Section 15.4 hereof.  SANO
              shall have a period of ten business  days from the date upon which
              copies of such  contract are actually  received by it as aforesaid
              to notify Par in writing  that it does not approve of the contract
              and failing  such notice  from SANO within such ten  business  day
              period SANO shall be deemed to have approved of such contract.



                                       31



         14.4 Confidentiality.

              (a) The parties agree that,  without the prior written  consent of
the other party (such consent not to be unreasonably  withheld) or except as may
be required  under law or court order,  the  provisions of the  Agreement  shall
remain confidential and shall not be disclosed to any Person not affiliated with
any of the parties.  

              (b) Par and SANO  hereby  agree  not to  reveal  or  disclose  any
Confidential  Information  (as  defined  below)  to  any  Person  without  first
obtaining  the  written  consent  of  the  disclosing  party,  except  as may be
necessary  in  regulatory   proceedings  or  litigation.   For  purposes  hereof
Confidential Information shall mean all information,  in whatever form, which is
or was  disclosed  by one party to another or to an Affiliate of the other prior
to or during  the term of this  Agreement  and which  relates  in any way to the
Products  or to  the  business  of  the  disclosing  party,  including,  without
limitation   information   relating  to  customers  and  pricing.   Confidential
Information  shall  not  include  information  that a party can  demonstrate  by
written evidence:  

                   (i) is in the public domain (provided that information in the
              public  domain has not and does not come into the public domain as
              a result of the  disclosure by the  receiving  party or any of its
              Affiliates);

                   (ii) is known to the receiving party or any of its Affiliates
              prior to the disclosure by the other party: or

                   (iii)  becomes  available to the party on a  non-confidential
              basis from a source  other than an  Affiliate of that party or the
              disclosing  party  and Par  covenants  and  agrees  to  cause  its
              Affiliates to comply with the provisions of this Section 14.4.

                                   ARTICLE XV

                          GENERAL TERMS AND CONDITIONS

         15.1 Force Majeure Clauses.  Neither party shall be considered to be in
default in respect of any obligation  hereunder,  other than the obligation of a
party to make  payment of amounts  due to the other  party  under or pursuant to
this  Agreement,  if failure of performance  shall be due to Force  Majeure.  If
either party is affected by a Force Majeure event,  such party shall,  within 20
days of its occurrence, give notice to the other party stating the nature of the
event, its anticipated  duration and any action being taken to avoid or minimize
its effect.  The suspension of performance  shall be of no greater scope and not
longer  duration  than is required  and the  non-performing  party shall use its
reasonable  best efforts to remedy its inability to perform.  The  obligation to
pay money in a timely  manner is absolute  and shall not be subject to the Force
Majeure  provisions,  except to the extent  prohibited by  governmental  rule or
regulations other than rules or regulations incident to bankruptcy or insolvency
proceedings of a party. Force Majeure shall mean an unforeseeable or unavoidable
cause  beyond the control and without the fault or  negligence  of a party (and,
where the party is Par,  beyond the control and without the fault or  negligence
of any of its Affiliates) including,  but not limited to, explosion,  flood, war

                                       32


(whether  declared  or  otherwise),  accident,  labor  strike,  or  other  labor
disturbance,  sabotage,  acts of God,  newly enacted  legislation,  newly issued
orders or decrees of any Court or of any  governmental  agency.  Notwithstanding
anything in this Section to the contrary,  the party to whom performance is owed
but to  whom it is not  rendered  because  of any  event  of  Force  Majeure  as
contemplated  in this Section  15.1 shall,  after the passage of one hundred and
twenty days,  have the option to terminate  this  Agreement on thirty days prior
written notice to the other party hereto. For greater  certainty,  the inability
or failure of Par to cause any of its  respective  Affiliates to comply with any
of the provisions of this Agreement  expressed o be applicable to its Affiliates
or which  require such party to cause the Affiliate to do or not to do something
shall not be considered Force Majeure unless the Affiliate in question is unable
to comply by reason of  unforeseeable  or unavoidable  causes beyond the control
and without the fault or negligence of such Affiliate.

         15.2 Arbitration.  All disputes arising out of, or in relation to, this
Agreement  (other than disputes  arising out of any claim by a third party in an
action commenced against a party), shall be referred for decision forthwith to a
senior executive of each party not involved in the dispute.  If no agreement can
be reached  through this process  within  thirty days of request by one party to
the other to nominate a senior  executive  for dispute  resolution,  then either
party hereto shall be entitled to refer such dispute to a single  arbitrator for
arbitration under Florida law, such arbitration to be held in Miami,  Florida on
an expedited  basis in accordance with the rules and regulations of the American
Arbitration  Association.  Any party demanding arbitration shall with service of
its demand for arbitration  propose a neutral arbitrator  selected by it. In the
event that the parties cannot agree upon a neutral arbitrator within thirty (30)
days after the demand for  arbitration,  an arbitrator shall be appointed by the
American Arbitration  Association who shall be a partner in a Miami, Florida law
firm having at least ten (10) partners.

         15.3  Assignment.  This  Agreement  may  not be  assigned  nor  can the
performance  of any duties  hereunder be delegated by Par or by SANO without the
prior  written  consent  of  the  other  parties,  which  consent  shall  not be

                                   ARTICLE XVI

                                GUARANTEE OF PRI

         16.1 Guarantee.  PRI does hereby unconditionally  guarantee to SANO the
full and prompt  payment and  performance  by Par of all of the  obligations  of
every  nature  whatsoever  to be  performed  by Par under  this  Agreement  (the
"Guaranteed  Obligations")  as and when  required to be paid or performed  under
this  Agreement.  The  guarantee  set  forth  in the  preceding  sentence  (this
"Guarantee") is an absolute,  unconditional and continuing guarantee of the full
and punctual payment and performance of the Guaranteed  Obligations and is in no
way conditioned  upon any requirement  that SANO first attempt to enforce any of
the Guaranteed  Obligations  against Par, any other  guarantor of the Guaranteed
Obligations  or any other  Person or  resort  to any  other  means of  obtaining
performance of any of the Guaranteed Obligations.  This Guarantee shall continue
in full force and effect until Par shall have satisfactorily  performed or fully
discharged all of the Guaranteed Obligations.  No performance or payment made by
Par, PRI, any other  guarantor or any other Person,  or received or collected by
SANO from Par, PRI, any other guarantor or any other Person in performance of or
in  payment of the  Guaranteed  Obligations  shall be deemed to  modify,  reduce
(except to the extent  that any such  performance  or payment  shall  reduce the
Guaranteed Obligations),  release or otherwise affect the liability of PRI under
this  Guarantee  which shall,  notwithstanding  any such payment or  performance
other than those made by PRI in respect of the  Guaranteed  Obligations or those
received or collected from PRI in respect of the Guaranteed Obligations,  remain
liable  for the  amount of the  Guaranteed  Obligations,  until  the  Guaranteed
Obligations are paid and performed in full.

         16.2 No Subrogation. Notwithstanding any payment or performance by PRI,
PRI shall not be entitled to be  subrogated  to any of the rights of SANO or any
other guarantor or any collateral security held by SANO against Par or any other
guarantor  or  any  collateral  security  for  the  payment  of  the  Guaranteed
Obligations,  nor  shall PRI seek or be  entitled  to seek any  contribution  or
reimbursement from Par or any other guarantor in respect of payments made by PRI
under this Guarantee.  PRI HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY AND
ALL  RIGHTS  AND  CLAIMS  WHICH  PRI MAY NOW  HAVE OR  HEREAFTER  ACQUIRE  TO BE
SUBROGATED  TO ANY SUCH  RIGHTS OF SANO AND TO SEEK OR BE  ENTITLED  TO SEEK ANY
SUCH  CONTRIBUTION  OR  REIMBURSEMENT  FROM  Par OR  ANY  OTHER  GUARANTOR.  THE

                                       36


OBLIGATIONS  OF AND WAIVERS BY PRI SET FORTH IN THIS SECTION 16.2 SHALL  SURVIVE
THE TERMINATION OF THIS GUARANTEE AND THE PAYMENT,  PERFORMANCE AND SATISFACTION
IN FULL OF ALL OF THE GUARANTEED OBLIGATIONS.

         16.3 Amendments, etc. with Respect to Guaranteed Obligations; Waiver of
Rights.  PRI shall remain obligated under this Guarantee  notwithstanding  that,
without any  reservation  of rights against PRI and without notice to or further
assent by PRI, any demand for payment or  performance  of any of the  Guaranteed
Obligations  made by SANO may be  rescinded  by SANO  and any of the  Guaranteed
Obligations continued,  and the Guaranteed Obligations,  or the liability of any
other  Person  upon or for any part  thereof,  or any  collateral  security  (or
guarantee  therefor  may,  from time to time,  in whole or in part,  be renewed,
extended, amended, modified,  accelerated,  compromised,  waived, surrendered or
released by SANO and this Agreement,  any collateral  security document or other
guarantee  or  document  in  connection  herewith  may  be  amended,   modified,
supplemented or terminated, in whole or in part, as SANO may deem advisable from
time to time, and any collateral  security or guarantee at any time held by SANO
for the  payment  or  performance  of the  Guaranteed  Obligations  may be sold,
exchanged,  waived,  surrendered or released. SANO shall not have any obligation
to  protect,  secure,  perfect  or  insure  any lien at any  time  held by it as
security for the  Guaranteed  Obligations  or for this Guarantee or any property
subject  thereto.  When making any demand  hereunder  against PRI, SANO may, but
shall be under no  obligation  to,  make a  similar  demand  on Par or any other
guarantor,  and any  failure by SANO to make any such  demand or to collect  any
payments  from Par or any such  other  guarantor  or any  release of Par or such
other guarantor  shall not relieve PRI of its  obligations or liabilities  under
this Guarantee, and shall not impair or affect the rights and remedies,  express
or implied, or as a matter of law, of SANO against PRI.

         16.4 Extent of Liability and Waivers.  PRI  understands and agrees that
the  obligation  of  guarantee  of PRI  pursuant to Section 16.1 are intended to
render PRI liable  hereunder  in each  instance  where Par would be liable under
this  Agreement,  and no more, and except that the  obligations of PRI hereunder
shall not be  discharged  by any  bankruptcy  or  similar  proceeding  which may
discharge Par herefrom.  Accordingly,  PRI acknowledges that it will not assert,
and hereby  waives to the fullest  extent  permitted by law, any rights to avoid
performance  hereunder available to it as guarantor which are not also available
to Par.  PRI waives any and all notice of the  creation,  renewal,  extension or
accrual of any of the Guaranteed  Obligations and notice of or proof of reliance
by SANO upon this  Guarantee or acceptance  of this  Guarantee;  the  Guaranteed
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred,  or renewed,  extended,  amended or waived,  in reliance
upon this Guarantee;  and all dealings  between Par or PRI, on the one hand, and
SANO on the other,  pursuant to this Agreement  shall  likewise be  conclusively
presumed to have been had or  consummated in reliance upon this  Guarantee.  PRI
waives diligence, presentment, protest, demand for payment and notice of default
or  nonpayment or  nonperformance  to or upon Par or any other  guarantors  with
respect to the  Guaranteed  Obligations.  When  pursuing its rights and remedies
hereunder  against PRI,  SANO may, but shall be under no  obligation  to, pursue

                                       37


such  rights and  remedies  as it may have  against  Par or any other  Person or
against any collateral security or guarantee for the Guaranteed Obligations, and
any  failure by PRI to pursue  such other  rights or  remedies or to collect any
payments  from  Par or any  such  other  Person  or to  realize  upon  any  such
collateral security or guarantee, or any release of Par or any such other Person
or any such  collateral  security  or  guarantee,  shall not  relieve PRI of any
liability  hereunder  and shall not impair or affect  the  rights and  remedies,
whether  express,  implied or available as a matter of law, of SANO against PRI.
This Guarantee shall remain in full force and effect and be binding upon PRI and
its  successors  and  assigns  and shall  inure to the  benefit  of SANO and its
successors  and assigns,  until all the Guaranteed  Obligations  shall have been
satisfied by payment and performance in full.

         16.5 Reinstatement.  This Guarantee shall continue to be effective,  or
be reinstated, as the case may be, if at any time payment or performance, or any
part  thereof,  of  any of the  Guaranteed  Obligations  is  rescinded  or  must
otherwise  be  restored or  returned  by SANO upon the  insolvency,  bankruptcy,
dissolution, liquidation or reorganization of Par or PRI, or upon or as a result
of the  appointment of a receiver,  intervenor or conservator  of, or trustee or
similar  officer  for,  Par or PRI,  or any  substantial  part  of its or  their
property, or otherwise, all as though such payments had not been made.

         16.6 No Waiver;  Cumulative Remedies. SANO shall not by any act (except
by a written instrument pursuant to Section 15.7), delay,  indulgence,  omission
or otherwise  be deemed to have waived any right or remedy  hereunder or to have
acquiesced in any breach of any of the terms and  conditions of this  Agreement.
No failure to exercise,  nor any delay in  exercising,  on the part of SANO, any
right, power or privilege hereunder shall operate as a waiver thereof. No single
or partial  exercise of any right,  power or privilege  hereunder shall preclude
any other or further exercise thereof or the exercise of any other right,  power
or  privilege.  A waiver  by SANO of any right or  remedy  hereunder  on any one
occasion  shall not be  construed as a bar to any right or remedy which the SANO
would  otherwise  have on any future  occasion.  The rights and remedies  herein
provided are cumulative,  may be exercised  singly or  concurrently  and are not
exclusive of any rights or remedies provided by law.

         16.7 Affiliates.  To the extent that Par or PRI is obligated  hereunder
to cause its  Affiliates to do or refrain from doing  anything,  PRI will do all
things that it may lawfully and reasonably do to cause such Affiliate to comply.




                                       38



         IN WITNESS WHEREOF, the parties have duly executed this Agreement as of
the Execution Date.
