calculation of Actual Q1 Sales and the amount of the Q1 Payment (if any) due, in
sufficient  detail to permit  Seller to  determine  whether the  calculation  of
Actual Q1 Units Sold or Actual Q1 Sales,  as the case may be, and the Q1 Payment
(if any) due is accurate.  Seller shall notify Buyer in writing  within five (5)
Business Days after  receiving the Quarter  Report of whether Seller agrees with
or disputes  Buyer's  calculation of Actual Q1 Units Sold or Actual Q1 Sales, as
the case may be, and the amount of the Q1  Payment  (if any).  In the event that
Seller agrees with Buyer's calculation of the Q1 Payment,  Seller shall promptly
pay any such Q1 Payment  to Buyer.  In the event that  Seller  disputes  Buyer's
calculation  of the Q1 Payment (if any),  the Parties  shall  attempt to resolve
such dispute in good faith.  The Q1 Payment (if any) to be made pursuant to this
Section 4.05 shall be paid by wire transfer of immediately available funds to an
account or accounts designated by Buyer in writing.

in such other form as Seller may  determine)  for all returned  Product  bearing
Seller's  NDC numbers and  evidenced by lot number as being sold by or on behalf
of Seller. Such handling of returned Products by Seller, and the issuance of any
credits or other form of  reimbursement  in  connection  therewith,  shall be in
accordance with Seller's then current returned goods policy. Buyer will process,
and be solely  responsible  for  reimbursements  with respect to Product returns
arising with respect to, or resulting from,  shipping errors,  damage in transit

          (i) All Products returned to Buyer through [***], bearing Seller's NDC
numbers and  evidenced  by lot number as sold by or on behalf of Seller shall be
the financial responsibility of Seller.

          (ii)  Effective  as of [***],  Buyer  shall be solely and  exclusively
responsible for processing any and all returned Products (including all returned
Products  bearing Seller's NDC's) and for the issuance of any and all credits or
other reimbursement  therefor.  Any and all returned Products received by Seller
on and after [***] will be  destroyed  by Seller,  and Seller  will,  after such
destruction,  forward  to Buyer  any  necessary  accompanying  documentation  to
determine the appropriate credit. Except as otherwise provided herein, Buyer and
Seller will not bill one another for costs incurred  strictly for the processing
of claims for returned Products. Seller and Buyer will use reasonable efforts in
requesting that customers direct all Product returns after [***] to Buyer.

          (iii)  Buyer  and  Seller  shall  be  responsible   for  handling  the
destruction  of any  Product  returned  to  their  respective  returns  handling
facility.  If  Buyer  or  Seller  destroys  Product  for  which  the  other  was

claim).  All payments due Seller under this Section  shall be made within thirty
(30)  days of  submission  to Buyer of  invoices  that  describe  the  requested
payments in reasonable detail.

a  chargeback  invoice  dated  (i.e.  date of sale  from the  wholesaler  to the
wholesaler customer,  subsequently  referred to as the "Activity Date") prior to
[***] (the  "Transition  Chargebacks").  Buyer shall process and be  financially
liable for all  chargeback  claims with an Activity  Date  subsequent  to [***].
Notwithstanding  the  foregoing,  the parties  acknowledge  that the VA National
Acquisition  Center  must  approve  the removal of the  Products  from  Seller's
Federal Supply  Schedule  ("FSS") before the  responsibility  of processing such
rebates is  transferred  from  Seller to Buyer.  Accordingly,  in the event such
approval is not obtained prior to [***], Seller shall continue to be responsible
for processing the FSS chargebacks on Buyer's behalf,  and Buyer shall reimburse
Seller for same.  Buyer and Seller agree that (a) Seller's  financial  liability
for the Transition  Chargebacks  shall be limited to those commercial  customers
with which Seller has chargeback obligations as of the Closing, and (b) any such
chargebacks issued by Seller shall be made on terms and conditions comparable to
Seller's  obligations  as of the Closing with respect to each customer and shall
be based on Seller's terms of respective agreements as of the Closing.

documentation  maintained by Buyer for the purpose of determining  compliance by
Buyer with its obligations under this Agreement.

maintain  the  Regulatory  Approvals  and perform  other  regulatory  compliance
activities  required to be  performed  under the  Regulatory  Approvals  (to the

Authorities  that are necessary to permit  Seller and its  Affiliates to provide
the maintenance and performance  contemplated by this Section 8.14. Buyer hereby

for  the  treatment  of  pediatric   urinary  tract   infection  which  contains
nitrofurantoin as its active pharmaceutical ingredient and has substantially the
same formulation as the Product (a "Competing Product"); provided, however, that

Affiliates,  which shall not exceed a [***] percent  ([***]%) equity interest in

Pharmaceuticals,  Inc. or any of their  Affiliates  from purchasing or otherwise
acquiring any Person (or part thereof) that engages in the activities  otherwise
restricted  pursuant  to this  Section  8.15 if such  Person's  total  sales  to
unaffiliated  entities  attributable  to Competing  Products on the date of such
purchase or  acquisition  or  thereafter  do not exceed  [***]  ([***]%) of such
Person's  total sales.  The Parties  hereto agree that the duration,  geographic
scope and other provisions set forth in this Section 8.16 are reasonable. In the
event that any court of competent  jurisdiction  determines  that the  duration,
geographic  scope  or any  other  provisions  are  unreasonable  and  that  such
provision is to that extent  unenforceable,  the parties  hereto agree that such
provision shall be interpreted in accordance  with Section 13.09 hereof.  Seller
agrees on behalf of itself and Elan  Pharmaceuticals,  Inc.  that damages are an
inadequate  remedy for any breach of the  provisions  set forth in this  Section
8.15 and that Buyer shall,  whether or not it is pursuing any potential remedies
at law, be  entitled to an  injunction  restraining  any further  breach of such
provisions.

     Section 8.16 Audit Financial Information.

     Buyer  has  informed  Seller  that  the  consummation  of the  transactions
contemplated  hereby will require Buyer to file a Current  Report on Form 8-K in
accordance  with the  Securities  Exchange Act of 1934, as amended and the rules
and regulations  promulgated  thereunder,  pursuant to Items 2 and 7 of Form 8-K
(the "8-K Filing").  Buyer  acknowledges  and agrees that subsequent to Closing,
Seller will  conduct an audit of certain  financial  information  related to the
Product and the Business  for purposes of making the 8-K Filing  pursuant to the
terms hereof,  with respect to the results of such audit to be provided to Buyer
on or before January 31, 2002.  During normal  business  hours,  upon reasonable
prior  notice and in such  manner as will not  unreasonably  interfere  with the
conduct of the business of Seller and its  Affiliates,  Seller shall provide and
shall cause its Affiliates to provide,  until  February 28, 2002,  Buyer and its
representatives  reasonable access to the books, records,  financial information

                                       26
<PAGE>

and personnel of Seller insofar as such books, records and financial information
relate to the  Product  and the  Business as  conducted  by Seller  prior to the
Closing Date as is  reasonably  necessary to make the 8-K Filing or an amendment
thereto.   All  costs  and   expenses   related  to  such  audit  shall  be  the
responsibility of the Buyer.  Buyer's access to such books,  records,  financial
information  and personnel of the Seller and its Affiliates  shall be subject to
the same  restrictions  as set forth in Section  13.01.  Any third party auditor
utilized  by Buyer  pursuant to this  Section  8.16 shall be selected by Seller,
subject  to Buyer's  prior  written  consent,  which  shall not be  unreasonably
withheld,  and such third party  auditor  will only be permitted to conduct such
audit if it  executes  a  confidentiality  agreement  with  Seller or any of its
Affiliates affected by such audit.

     Section 8.17 Government Multi-Product Contracts.

     From and after  the  Closing  Date,  Buyer  shall  honor  and  perform  all
obligations and liabilities of Seller arising subsequent to Closing and relating
to the Product  under and pursuant to each  Government  Multi-Product  Contract,
until  such time as Seller has  terminated  each such  Government  Multi-Product
Contract as provided  below.  Seller  agrees that after the Closing Date it will
not take any action with respect to any Government  Multi-Product  Contract that
would extend the term of such Government  Multi-Product contract with respect to
the Product,  create or agree to any additional  obligations with respect to the
Product, or otherwise adversely affect Buyer or the Business,  without the prior
written consent of Buyer,  although  Seller may enter into a separate  agreement
with such  government  party,  provided that such  agreements do not contain any
provisions  relating to the Product or the Business.  Buyer hereby covenants and
agrees to use all  commercially  reasonable  efforts to enter into  Contracts as
soon as  practicable  after the  Closing by which  Buyer will  dispense  Product
through a Governmental or Regulatory  Authority (such as the Medicaid program or
a state  equivalent),  together  with  other  pharmaceutical  products  of Buyer
("Buyer Government  Multi-Product  Contracts").  Seller agrees to coordinate its
termination of the rights and  obligations of Seller with respect to the Product
under each Government  Multi-Product  Contract,  to the extent  permitted by the
terms thereof,  with Buyer's  timing of Buyer's entry into the Buyer  Government
Multi-Product Contracts.

     Section 8.18 Further Assurances.

     (a) On and after  the  Closing,  Seller  shall  from  time to time,  at the
request of Buyer,  execute and deliver,  or cause to be executed and  delivered,
such other instruments of conveyance and transfer and take such other actions as
Buyer  may  reasonably  request,  in order to more  effectively  consummate  the
transactions  contemplated hereby and to vest in Buyer good and marketable title
to the Purchased Assets and the Product Inventory.

substantially the same terms and conditions as currently in effect.

     (d)  Seller  shall use all  commercially  reasonable  efforts to obtain for
Buyer,  without  cost  to  Buyer,  through  Seller's  negotiations  with  P&G an

agreement with P&G to supply to Buyer for at least five (5) years  subsequent to
Closing nitrofurantoin as the active pharmaceutical ingredient of the Product.

     (e) On and after the Closing, Buyer shall from time to time, at the request
of Seller,  take such actions as Seller may reasonably request, in order to more
effectively consummate the transactions  contemplated hereby,  including Buyer's
assumption of the Assumed Liabilities.

     Section 8.19 Notice to Customers.

     Seller  agrees  to  cooperate  with  Buyer,  at  Buyer's  request,  in  the
notification to customers of the transactions contemplated by this Agreement and
Seller  agrees not to notify  any  customer  of such  transactions  without  the
consent  of Buyer.  Such  notification  shall be in such  form as is  reasonably
satisfactory  to both  Buyer  and  Seller  and  shall be  negotiated  as soon as
reasonably practicable after the Closing.

     Section 11.02 Indemnification.

     (a) By Seller.  Subject to Sections  11.03 and 11.04 of this  Agreement and
Section 8.14 of the Supply Agreement,  from and after the Closing,  Seller shall
indemnify,  reimburse, defend and hold harmless Buyer, its Affiliates, and their
respective  officers,  directors,  employees,  agents,  successors  and  assigns
(collectively,  the "Buyer  Indemnified  Parties")  from and against any and all
costs, losses, Liabilities, damages, lawsuits, deficiencies, claims and expenses
(including  interest,   penalties  and  reasonable  fees  and  disbursements  of
attorneys  and experts paid in  connection  with the  investigation,  defense or
settlement of any of the foregoing) (collectively, the "Damages"), to the extent
relating to or resulting from (i) any inaccuracy or breach of any representation
or warranty of Seller herein or in any other Seller Closing  Document;  (ii) any
breach or default of a covenant or agreement  of Seller  herein or in any Seller
Closing  document;  (iii) Seller's  conduct of the Business prior to the Closing
(other than with  respect to the Assumed  Liabilities);  and (iv) the failure of
Seller to pay, perform or discharge any Excluded Liabilities.

     (b) By Buyer.  Subject  to  Sections  11.03 and  11.04,  from and after the
Closing, Buyer shall indemnify,  reimburse, defend and hold harmless Seller, its
Affiliates  and  their  respective  officers,   directors,   employees,  agents,
successors and assigns (collectively, the "Seller Indemnified Parties") from and
against any and all Damages  resulting  from (i) any inaccuracy or breach of any
representation  or warranty of Buyer  herein or in any Buyer  Closing  Document,
(ii) any breach or default of a covenant or  agreement of Buyer herein or in any
Buyer Closing Document; (iii) Buyer's conduct of the Business from and after the
Closing;  (iv) the  failure of Buyer to pay,  perform or  discharge  any Assumed
Liabilities; and (v) any payments that Seller may be obligated to make on behalf
of Buyer under any agreement between Buyer and P&G.

     (c) Procedures.  The indemnified Party (the "Indemnified Party") shall give
the  indemnifying  Party (the  "Indemnifying  Party")  prompt written notice (an
"Indemnification  Claim  Notice") of any Damages or discovery of fact upon which
such  Indemnified  Party  intends to base a request  for  indemnification  under
Section 11.02(a) or Section 11.02(b),  provided that no delay on the part of the
Indemnified  Party  in  notifying  the  Indemnifying  Party  shall  relieve  the
Indemnifying  Party from any obligation  hereunder unless the Indemnifying Party
is materially prejudiced thereby. Each Indemnification Claim Notice must contain
a reasonable  description of the claim and the nature and amount of such Damages
(to the extent  that the nature  and  amount of such  Damages  are known at such
time). The Indemnified  Party shall furnish  promptly to the Indemnifying  Party
copies of all papers and official  documents received in respect of any Damages.
All  indemnification  claims in  respect  of a Party,  its  Affiliates  or their
respective  directors,   officers,  employees  and  agents  (collectively,   the
"Indemnitees"  and each an  "Indemnitee")  shall be made solely by such Party to
this Agreement.

     (d) Third Party Claims. The obligations of an Indemnifying Party under this
Section  11.02 with  respect to Damages  arising  from claims of any third party
that are  subject to  indemnification  as  provided  for in Section  11.02(a) or
Section  11.02(b) (a "Third Party  Claim")  shall be governed upon the following
additional terms and conditions:

                                       30
<PAGE>

          (i) At its option,  the  Indemnifying  Party may assume the defense of
any Third Party Claim by giving written notice to the  Indemnified  Party within
thirty (30) days after the  Indemnifying  Party's receipt of an  Indemnification
Claim  Notice.  The  assumption  of the  defense of a Third  Party  Claim by the
Indemnifying  Party  shall  not  be  construed  as an  acknowledgment  that  the
Indemnifying Party is liable to indemnify any Indemnitee in respect of the Third
Party Claim, nor shall it constitute a waiver by the  Indemnifying  Party of any
defenses it may assert against any Indemnitee's claim for indemnification.  Upon
assuming the defense of a Third Party Claim, the Indemnifying  Party may appoint
as lead  counsel  in the  defense  of the Third  Party  Claim any legal  counsel
selected  by  the  Indemnifying  Party  that  is  reasonably  acceptable  to the
Indemnified  Party. In the event the Indemnifying Party assumes the defense of a
Third  Party  Claim,  the  Indemnified  Party  shall  promptly  deliver  to  the
Indemnifying  Party all original notices and documents  (including court papers)
received by any Indemnitee in connection with the Third Party Claim.  Should the
Indemnifying Party assume the defense of a Third Party Claim, except as provided
in  subsection  (ii) below,  the  Indemnifying  Party shall not be liable to the
Indemnified  Party or any other  Indemnitee for any legal expenses  subsequently
incurred by such  Indemnified  Party or other  Indemnitee in connection with the
analysis,  defense or settlement of the Third Party Claim.  In the event that it
is  ultimately  determined  that  the  Indemnifying  Party is not  obligated  to
indemnify,  defend or hold  harmless  an  Indemnitee  from and against the Third
Party Claim, the Indemnified  Party shall reimburse the  Indemnifying  Party for
any and all costs and expenses (including attorneys' fees and costs of suit) and
any Damages incurred by the Indemnifying Party in its defense of the Third Party
Claim with respect to such Indemnitee.

          (ii) Without  limiting  Section  11.02(d)(i),  any Indemnitee shall be
entitled to  participate  in, but not  control,  the defense of such Third Party
Claim and to employ counsel of its choice for such purpose;  provided,  however,
that such  employment  shall be at the  Indemnitee's  own expense unless (A) the
employment   thereof  has  been  specifically   authorized  in  advance  by  the
Indemnifying  Party in writing,  (B) the Indemnifying Party has failed to assume
the defense and employ counsel in accordance with Section  11.02(d)(i) (in which
case the Indemnified  Party shall control the defense) or (C) if the Indemnified
Party and the  Indemnifying  Party are both named parties to the  proceeding and
the  Indemnified  Party has  reasonably  concluded that there may be one or more
legal defenses that are different from or in addition to those  available to the
Indemnifying  Party (in which  case the  Indemnifying  Party  shall not have the
right to assume the  defense of such action on behalf of the  Indemnified  Party
and the  Indemnifying  Party shall be liable for all legal expenses  incurred by
the Indemnified Party in furtherance thereof).

          (iii) With  respect to any Damages  relating  solely to the payment of
money damages in connection with a Third Party Claim and that will not result in
the  Indemnitee's  becoming  subject to  injunctive or other relief or otherwise
materially adversely affect the business of the Indemnitee in any manner, and as
to  which  the  Indemnifying  Party  shall  have  acknowledged  in  writing  the
obligation to indemnify the Indemnitee  hereunder,  the Indemnifying Party shall
have the sole  right to  consent  to the entry of any  judgment,  enter into any
settlement  or  otherwise  dispose  of  such  Damages,  on  such  terms  as  the
Indemnifying  Party,  in its  reasonable  discretion,  shall  deem  appropriate;
provided,  however,  that the  Indemnifying  Party  shall  have  obtained a full
release  from  such  Third  Party in  connection  with any  such  settlement  or
disposition.  With respect to all other Damages in  connection  with Third Party

                                       31
<PAGE>

                                        [***] - CONFIDENTIAL TREATMENT REQUESTED

Claims,  where the Indemnifying Party has assumed the defense of the Third Party
Claim in accordance with Section 11.02(d)(i),  the Indemnifying Party shall have
authority to consent to the entry of any judgment,  enter into any settlement or
otherwise  dispose of such  Damages;  provided that it obtains the prior written
consent  of the  Indemnified  Party  (which  consent  shall not be  unreasonably
withheld  or  delayed).  The  Indemnifying  Party  shall not be  liable  for any
settlement  or other  disposition  of Damages by an  Indemnitee  that is reached
without the written consent of the  Indemnifying  Party (which consent shall not
be  unreasonably  withheld or delayed).  Regardless of whether the  Indemnifying
Party chooses to defend or prosecute any Third Party Claim, no Indemnitee  shall
admit any liability  with respect to, or settle,  compromise  or discharge,  any
Third Party Claim without the prior written  consent of the  Indemnifying  Party
which consent shall not be unreasonably withheld or delayed.

          (iv) Regardless of whether the Indemnifying Party chooses to defend or
prosecute any Third Party Claim,  the Indemnified  Party shall,  and shall cause
each other  Indemnitee to,  cooperate in the defense or prosecution  thereof and
shall furnish such records,  information  and testimony,  provide such witnesses
and attend such conferences, discovery proceedings, hearings, trials and appeals
as may be reasonably requested in connection  therewith.  Such cooperation shall
include access during normal business hours afforded to the  Indemnifying  Party
to,  and  reasonable   retention  by  the  Indemnified  Party  of,  records  and
information  that are reasonably  relevant to such Third Party Claim, and making
Indemnitees  and other employees and agents  available on a mutually  convenient
basis to provide additional information and explanation of any material provided
hereunder,  and the Indemnifying Party shall reimburse the Indemnified Party for
all its  reasonable  out-of-pocket  expenses  in  connection  therewith.  If the
Indemnified  Party  controls the defense of the claim,  the  Indemnifying  Party
shall cooperate with the Indemnified Party on the terms described above.

     (e) Expenses.  Except as provided above, the costs and expenses,  including
fees  and  disbursements  of  counsel,  incurred  by the  Indemnified  Party  in
connection  with any  claim  shall be  reimbursed  on a  quarterly  basis by the
Indemnifying  Party,  without  prejudice to the  Indemnifying  Party's  right to
contest the Indemnified  Party's right to indemnification  and subject to refund
in the event the  Indemnifying  Party is ultimately  held not to be obligated to
indemnity the Indemnified Party.

     Section 11.03 Limitations.

     (a) In no event shall Seller be liable for any Damages  pursuant to Section
11.02(a) of this  Agreement  unless and until the  aggregate  amount of all such
Damages under this Agreement exceeds [***] Dollars ([***]), in which case Seller
shall be liable for all such Damages  including the first [***] Dollars ($[***])
of Damages.

     (b) In no event  shall the  aggregate  liability  of Seller for any Damages
pursuant to Section  11.02(a) exceed an aggregate  amount equal to [***] Dollars
($[***]);  and further,  in no event shall the aggregate liability of Seller for
any Damages  other than  Damages  arising out of Third Party  Claims  based upon
product  liability claims or threatened  claims or injuries caused by either (x)
Product  sold prior to the Closing or (y) Product  Inventory  (other than to the
extent  that the  subject  product  liability  claims  or  threatened  claims or

                                       32
<PAGE>

injuries  with respect to Product  Inventory are due to the acts or omissions of
Buyer) exceed an aggregate amount equal to [***] Dollars ($[***]).

     (c) The amount of any Damages  under Section  11.02(a) or Section  11.02(b)
shall be reduced by the amount of any insurance proceeds paid to the Indemnified
Party relating to such claim.

     (d) Except with respect to claims based on fraud, notwithstanding any other
terms or  provisions  of this  Agreement  or any  terms or  provisions  under or
pursuant to any other agreement to which Buyer and Seller are parties, including
the Supply Agreement  (including  Section 8.14 thereof),  the right of the Buyer
Indemnified  Parties to indemnification  under this Article XI shall be the sole
and exclusive remedy, without duplication, of the Buyer Indemnified Parties with
respect to claims incurred in connection with, arising out of, resulting from or
incident to (i) any  inaccuracy or breach of any  representation  or warranty of
Seller  herein or in any  other  Seller  Closing  Document;  (ii) any  breach or
default of a covenant or  agreement  of Seller  herein,  or in any other  Seller
Closing  document;  (iii) Seller's conduct of the Business prior to the Closing;
or (iv) the  failure  of  Seller  to pay,  perform  or  discharge  any  Excluded
Liabilities.

     (e) Except with respect to claims based on fraud, notwithstanding any other
terms or  provisions  of this  Agreement  or any  terms or  provisions  under or
pursuant to any other agreement to which Buyer and Seller are parties, including
the Supply Agreement  (including Section 8.14 thereof),  the right of the Seller
Indemnified  Parties to indemnification  under this Article XI shall be the sole
and exclusive remedy,  without  duplication,  of the Seller Indemnified  Parties
with respect to claims incurred in connection  with,  arising out of,  resulting
from or  incident  to (i) any  inaccuracy  or  breach of any  representation  or
warranty of Buyer herein or in any other Buyer Closing Document; (ii) any breach
or default of a covenant  or  agreement  of Buyer  herein or in any other  Buyer
Closing  Document;  (iii)  Buyer's  conduct of the  Business  from and after the
Closing;  or (iv) the failure of Buyer to pay,  perform or discharge any Assumed
Liabilities;  and (v) any payments that Seller is obligated to make on behalf of
Buyer under any agreement between Buyer and P&G.

     Section 11.04 Limitation of Liability

     NOTWITHSTANDING  ANYTHING  TO THE  CONTRARY IN THIS  AGREEMENT  (SUBJECT TO
SECTION 8.14 OF THE SUPPLY AGREEMENT),  NEITHER SELLER NOR ANY OF ITS AFFILIATES
SHALL BE LIABLE TO THE BUYER OR ANY THIRD PARTY BY REASON OF ANY  REPRESENTATION
OR  WARRANTY,  CONDITION  OR OTHER TERM OR ANY DUTY OF COMMON  LAW, OR UNDER THE
EXPRESS TERMS OF THIS AGREEMENT, FOR ANY CONSEQUENTIAL, SPECIAL OR INCIDENTAL OR
PUNITIVE LOSS OR DAMAGE (WHETHER FOR LOSS OF CURRENT OR FUTURE PROFITS,  LOSS OF
ENTERPRISE  VALUE OR  OTHERWISE)  AND WHETHER  OCCASIONED  BY THE  NEGLIGENCE OF
SELLER  OR ITS  AFFILIATES  OR  ANY OF  THEIR  RESPECTIVE  OFFICERS,  DIRECTORS,
EMPLOYEES, AGENTS OR REPRESENTATIVES.

                      Article XII. [Intentionally Omitted]

                          Article XIII. Miscellaneous

     Section 13.01 Confidentiality.

     (a) In addition to the  restrictions  contained in Section 8.03,  after the
Closing,  no Party (a  "Disclosing  Party")  shall,  without  the prior  written
consent of the other Party (the "Non-disclosing Party"),  disclose to any Person
Confidential  Information (as defined below) of the Non-disclosing Party, except
to a Disclosing Party's or its Affiliates  employees or representatives who need
to know such information for any reason contemplated by this Agreement (and then
only to the extent that such  persons are under an  obligation  to maintain  the
confidentiality  of  the  Confidential  Information),  or use  any  Confidential
Information of the  Non-disclosing  Party for any reason other than contemplated
by this  Agreement  unless  such  Disclosing  Party has (i)  consulted  with the
Non-disclosing  Party and  obtained the  Non-disclosing  Party's  prior  written
consent, and (ii) been advised by counsel that disclosure is required to be made
under  applicable Law or the requirements of a national  securities  exchange or
another  similar  regulatory  body.  In the event that the  Disclosing  Party is
requested  or required  by  documents,  subpoena,  civil  investigative  demand,
interrogatories,  requests for information, or other similar process to disclose
any   Confidential   Information,   the  Disclosing   Party  shall  provide  the
Non-disclosing  Party with prompt  written  notice of such request or demands or
other similar process so that the  Non-disclosing  Party may seek an appropriate
protective  order  or,  if such  request,  demand or other  similar  process  is
mandatory,  waive the Disclosing  Party's compliance with the provisions of this
Section 13.01(a) as appropriate.

     (b) The term "Confidential Information" as used in this Section 13.01 means
(i) as to Buyer, all confidential  information relating to Buyer's business, the
Purchased Assets, the Product Inventory and the Assumed Liabilities, and (ii) as
to Seller, all confidential information relating to the Business (other than the
Purchased  Assets,  Product  Inventory  and  the  Assumed  Liabilities)  and the
business and operations of the Seller and its Affiliates, including the Excluded
Assets and the Excluded  Liabilities or other obligations other than the Assumed
Liabilities,  in each of (i) and (ii)  whether  disclosed  prior to or after the
date hereof.  The term "Confidential  Information" does not include  information
which  becomes  generally  available  to the  public  other  than as a result of
disclosure by the Disclosing Party, or becomes available to the Disclosing Party
on a non-confidential  basis from a source other than the Non-disclosing  Party,
provided that such source is not bound by a  confidentiality  agreement with the
Non-disclosing Party.

     (c) This Section 13.01 supercedes and replaces in its entirety that certain
letter agreement  relating to  confidentiality  previously  entered into between
Seller or its  Affiliate  and Buyer in connection  with the  negotiation  of the
transactions contemplated by this Agreement.

     Section 13.02 Notices.

     All notices, requests and other communications hereunder must be in writing
and will be deemed to have been duly given only if delivered  personally against
written receipt or by facsimile  transmission  with answer back  confirmation or

of the Party  waiving such term or  condition.  No waiver by any Party hereto of

will not be required  with  respect to an  assignment  by either Party (i) to an
Affiliate of such Party so long as such Party remains bound by the terms hereof;
or  (ii)  in  connection  with a  merger,  sale  or  transfer  involving  all or
substantially  all of the assets of such Party.  This Agreement is binding upon,

affected thereby, (a) such provision will be fully severable, (b) this Agreement
will be construed  and  enforced as if such  illegal,  invalid or  unenforceable
provision had never compromised a part hereof,  (c) the remaining  provisions of
this  Agreement will remain in full force and effect and will not be affected by
the illegal,  invalid or unenforceable  provision or by its severance  herefrom,
and (d) in lieu of such illegal, invalid or unenforceable provision,  there will
be  added  automatically  as a  part  of  this  Agreement  a  legal,  valid  and
enforceable  provision  as  similar  to  terms  to  such  illegal,   invalid  or
unenforceable  provision as may be possible  and  reasonably  acceptable  to the
Parties herein.
