          for the first  Quarter  Period and the second  Quarter  Period  ending
          December 31, 1997. The final Additional Consideration Payment shall be

          U.S. patents included in the Patents; and (B) ten percent (10%) of Net
          Sales for the relevant Quarter Period of any products  marketed by the
          Buyer as  substitute  treatment  products  for  either  of the two (2)
          Viractin Cold Sore and Fever Blister Treatment products existing as of
          the date of this Agreement,  if such substitute  products are marketed
          under  the  Viractin(R)  brand  name  (The  products  referred  to  in
          subparagraph (ii) hereof are collectively  referred to as the "Covered
          Products.");

                    (iii) For purposes of calculating  Additional  Consideration
          Payments,  "Net Sales" shall mean the invoiced  price  received by the
          Buyer for the  Covered  Products  sold to third  parties  during  each
          Quarter Period less (A) cash discounts or accruals  actually  allowed;
          (B) credits  and/or  cash  refunds or  accruals  actually  allowed for
          damaged or  returned  products;  (C) trade  discounts  and  allowances
          actually  paid or allowed  (with  respect to (A), (B) and (C), in each
          case, as long as such  discounts and allowances are for the purpose of
          enhancing sales of the Covered  Products);  and (D) sales or use taxes
          (other than income taxes);

                    (iv) For purposes of  calculating  Additional  Consideration
          Payments,  with  respect to sales of the  Covered  Products in foreign
          countries,  the Seller shall  calculate Net Sales in each such country
          on a monthly  basis and convert  such amount into U.S.  Dollars  based
          upon the exchange  rate as reported in The Wall Street  Journal on the
          last business day of the month. Such monthly figures shall be included
          in the statement  reflecting  the Net Sales  calculations  as provided
          herein;

                    (v)  As  set  forth  above,  each  Additional  Consideration
          Payment shall be accompanied by a statement of Net Sales in sufficient
          detail  to  permit  confirmation  of the  accuracy  of the  Additional
          Consideration  Payment made, including without limitation,  the number
          of Covered  Products sold by the Buyer from the Viractin Product Line,
          the gross sales and Net Sales by the Buyer from the  Viractin  Product
          Line, the Additional Consideration Payment, in U.S. dollars,  payable,
          the method used to calculate the Additional  Consideration Payment and
          the exchange rates used;

                    (vi) In the event that any Additional  Consideration Payment
          due  hereunder  is not made when due,  such  Additional  Consideration
          Payment  shall  accrue  interest  from the date due at the rate of one
          percent (1%) per month; provided, however, that in no event shall such
          rate exceed the maximum  legal annual  interest  rate.  The payment of
          such interest shall not limit Seller from  exercising any other rights
          it may have as a consequence of the lateness of any payment;



                                      -7-



                    (vii) For a period of one (1) year from the date upon  which
          an  Additional  Consideration  Payment is made,  the Buyer  shall keep
          complete  and  accurate  records  pertaining  to  the  sale  or  other
          disposition  of Covered  Products  sold by the Buyer from the Viractin
          Product Line in sufficient  detail to permit the Seller to confirm the
          accuracy of such Additional  Consideration  Payment.  The Seller shall
          have the  right to  review  such  records  to  confirm  Net  Sales and
          Additional Consideration Payments for the preceding calendar year (the
          "Seller's  Audit").  The Seller's Audit may be exercised during normal
          business  hours not more than  once a year upon at least  thirty  (30)
          working days' prior written notice to the Buyer. The Seller shall bear
          the full cost of the Seller's Audit.

                    (viii) If after completion of the Seller's Audit, the Seller
          disagrees with the accuracy of the Additional  Consideration Payments,
          the Seller shall notify the Buyer of such disagreement and its reasons
          for so  disagreeing,  in which  case the  Seller  and the Buyer  shall
          attempt to resolve the disagreement. If within ten (10) days after the
          Buyer's receipt of the notice,  the Seller and the Buyer are unable to
          resolve the disagreement,  they shall submit the records pertaining to
          the sale or other  disposition of Covered  Products to an independent,
          certified public accountant (the "Accountant")  reasonably  acceptable
          to  both  parties  for  a  binding  and  nonappealable   determination
          regarding  Net  Sales  and  Additional   Consideration  Payments  (the
          "Accountant's  Audit").  Such  determination  shall be rendered within
          thirty (30) days after submission to the Accountant.  The Seller shall
          bear the full cost of the Accountant's  Audit unless such Accountant's
          Audit  discloses  an amount owed the Seller of more than five  percent
          (5%)  from  the  amount  actually  paid to the  Seller  as  Additional
          Consideration Payments for the period of such audit. In such case, the
          Buyer shall bear the full cost of the Accountant's Audit.

          2.2. Allocation. The Purchase Price shall be allocated to the Viractin
Product Line and the Purchased Assets, and such allocation shall be used for all
purposes,  including the preparation and filing of Internal Revenue Service Form
8594 with respect to the transactions contemplated hereby.

                                  ARTICLE III.

                  REPRESENTATIONS AND WARRANTIES OF THE SELLER

          The Seller  represents and warrants to the Buyer as of the date hereof
as follows:

          4.1. Organization and Qualification.  The Seller is a corporation duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction  of its  organization,  with all requisite power and authority and,
except for the rights granted the Seller's Licensee, which rights will terminate
on the  Transition  Date,  has a legal  right to own,  operate  and carry on the
Viractin  Product  Line.  The Seller is duly  qualified to do business and is in
good standing in every  jurisdiction  where Seller's  conduct of the business of
the  Viractin  Product  Line  requires  such   qualification,   except  in  such
jurisdictions  where the failure to so qualify would not have a material adverse
effect on the business,  revenues,  financial condition,  properties,  assets or
prospects of the Viractin Product Line.

          4.2. Authorization. The Seller has full corporate power, authority and
legal  right to execute  and  deliver  and,  except for the rights  granted  the
Seller's  Licensee,  which rights will  terminate  on the  Transition  Date,  to
perform its obligations under this Agreement. The execution and delivery of this
Agreement  by the Seller and the  performance  by the Seller of its  obligations
hereunder  have  been  duly  authorized  by  all  requisite   corporate  action,
including,  without limitation,  by its Board of Directors and stockholders.  No
other action on the part of the Seller is necessary to authorize  the  execution
and delivery of this Agreement or the  performance  of the Seller's  obligations



                                      -10-



hereunder.  This  Agreement has been duly and validly  executed and delivered by
the Seller and constitutes a legal,  valid and binding obligation of the Seller,
enforceable  against  the Seller in  accordance  with its  terms,  except to the
extent  that  such   enforcement  may  be  subject  to  applicable   bankruptcy,
insolvency, reorganization, moratorium or other similar laws now or hereafter in
effect relating to creditors' rights and remedies generally.

          4.3.  No  Violation.  Neither  the  execution  and  delivery  of  this
Agreement  by the Seller,  the  consummation  of the  transactions  contemplated
hereby, nor the performance by the Seller of its obligations hereunder will:

               (a)  Violate  or result in any  breach  of any  provision  of the
          Certificate of Incorporation and/or By-laws of the Seller;

               (b)  Violate,  conflict  with  or  result  in  a  breach  of,  or
          constitute  a default  (with or without due notice or lapse of time or
          both)  under,   or  permit  the  termination  of,  or  result  in  the
          acceleration  of, or entitle any party to  accelerate  any  obligation
          under,  or  result  in the  loss of any  benefit  from,  any  material
          contract, agreement or arrangement, whether written or oral, formal or
          informal;

               (c) Result in the imposition or creation of any pledges, security
          interests,   liens,  mortgages,   claims,  debts,  charges,  or  other
          encumbrances or restrictions on transfer of any kind whatsoever (each,
          an "Encumbrance") upon any of the Purchased Assets; or

               (d)  Violate  any  order,  writ,  judgment,  injunction,  decree,
          statute,   law,  rule,   regulation  or  ordinance  of  any  court  or
          governmental, quasi-governmental or regulatory department or authority
          ("Governmental  Authority")  applicable  to the Seller,  the  Viractin
          Product Line or the Purchased Assets.

          4.4. Consents and Approvals.  Other than the consents and approvals of
or  filings  or  registrations  with  the  governmental,  quasi-governmental  or
regulatory  departments and authorities  listed on Section 4.4 of the Disclosure
Schedule,  no  filing  or  registration  with,  no  notice  to  and  no  permit,
authorization,  consent or approval of any governmental,  quasi-governmental  or
regulatory  department  or authority is necessary for the execution and delivery
of this Agreement or the  consummation  of the purchase and sale of the Viractin
Product Line.

          4.5.  Inventory.  To the Seller's  Knowledge,  all  finished  goods in
Inventory (i) are of good merchantable  quality and are suitable for retail sale
in the ordinary  course of business,  (ii) have been  manufactured in accordance
with good  manufacturing  practices,  as defined by the Federal  Food,  Drug and
Cosmetic Act, as amended (the "FDA Act") and (iii) have not been  adulterated or
misbranded  within  the  meaning  of the FDA Act,  or the rules and  regulations
promulgated thereunder.



                                      -11-



          4.6. Litigation.  Except as set forth in Section 4.6 of the Disclosure
Schedule,  there  is  no  action,  suit,  inquiry,  judicial  or  administrative
proceeding,  arbitration or investigation (collectively referred to as "Claims")
relating  to the  Viractin  Product  Line or the  Purchased  Assets,  including,
without  limitation,  Claims relating to product  liability or consumer  safety,
pending or  threatened  against the Seller or, to the  Seller's  Knowledge,  the
Seller's   Licensee,   before  any  court,   arbitrator  or   administrative  or
governmental body, nor is there any judgment, decree, injunction,  rule or order
of any court, governmental department,  commission,  agency,  instrumentality or
arbitrator  outstanding  against,  and  unsatisfied  by,  the  Seller or, to the
Seller's knowledge, the Seller's Licensee, relating to the Viractin Product Line
or the  Purchased  Assets  (any of the  foregoing  being  herein  referred to as
"Existing Litigation"), nor does the Seller know of any fact, event or condition
which could  reasonably be expected to serve as a basis for the assertion of any
Claim.  Without  limiting  the  generality  of  the  foregoing,   there  are  no
investigations or proceedings  currently existing or threatened  relating to the
Viractin  Product  Line  or the  Purchased  Assets  before  the  Food  and  Drug
Administration (the "FDA") or any similar agency (whether federal or state), and
all such  investigations or proceedings during the last five (5) years are fully
set forth in Section 4.6 of the Disclosure Schedule.

          4.7.  Title to  Assets.  Except for the rights  granted  the  Seller's
Licensee which rights will terminate on the Transition Date, the Seller has good
and marketable title to all of the Purchased  Assets,  free and clear of any and
all Encumbrances,  and the Purchased Assets are all of the properties and assets
that are,  individually  or in the aggregate,  material to the Viractin  Product
Line.

          4.8. Material Contracts.

               (a) Other than the Seller's  Licensee  Agreement,  as modified by
          the Termination  Agreement,  and the Termination  Agreement,  true and
          correct copies of which are attached  hereto as Exhibit  4.8(a)(i) and
          4.8(a)(ii),  respectively,  there  are  no  contracts,  agreements  or
          arrangements,  whether written or oral, formal or informal,  which are
          material to the  Viractin  Product Line to which the Seller is a party
          or, to the Seller's Knowledge, which will survive the Closing Date and
          which  would  adversely  impact the Buyer's  ability to  exercise  its
          ownership rights to the Viractin Product Line or the Purchased Assets.

               (b)  The  execution,  delivery  and  performance  of  each of the
          Seller's  Licensee  Agreement and the  Termination  Agreement has been
          duly  authorized  by all  requisite  corporate  action  and each  such
          agreement  is in full force and effect  (with  regard to the  Seller's
          Licensee Agreement,  as such agreement was modified by the Termination
          Agreement).  Neither the Seller nor, to the  Seller's  Knowledge,  the
          Seller's Licensee has breached either of such agreements. There exists
          no event, occurrence or act (including the execution of this Agreement
          and the consummation



                                      -12-



          of the  transactions  contemplated  hereby) which,  with the giving of
          notice  or the  lapse of  time,  or both,  could  reasonably  become a
          default by the Seller under either of such agreements.

               (c)  Section  4.8(c) to the  Disclosure  Schedule  describes  all
          commitments   and  obligations   with  respect  to  trade   promotions
          (including  coop   advertising),   refunds  and  similar   promotional
          campaigns  and all  consumer  promotions,  such as  coupons,  rebates,
          refunds and similar  promotional  campaigns,  relating to the Viractin
          Product Line, which are known by Seller.

          4.9. Permits. Section 4.9 of the Disclosure Schedule sets forth all of
the licenses, franchises, permits, consents and authorizations necessary for the
lawful conduct of the business of the Viractin Product Line.

          4.10. Broker's Fees and Commissions. Neither the Seller nor any of its
directors,  officers,  employees or agents has employed any  investment  banker,

          list of all of the Trademarks,  Patents and Copyrights included in the

          the Seller's Licensee,  which rights will revert back to the Seller on
          the Transition Date, the Seller is the sole and exclusive owner of the
          Proprietary  Rights,  and has the  sole  and  exclusive  right to use,
          license,  sublicense,  assign or sell the  Proprietary  Rights without
          liability to, or consent of, any person or entity;

               (b) Except for the rights  granted to  Seller's  Licensee,  which
          rights will terminate on the Transition Date, the ownership and use of
          the Proprietary  Rights by the Buyer will not infringe upon the rights
          of any  person or  entity,  whether  or not  registered,  patented  or
          copyrighted.  The Seller has not received any notice of a claim of any
          infringement nor were any such claims the subject of any action,  suit
          or  proceeding  involving  the  Seller,  or to the  best  of  Seller's
          knowledge, the Seller's Licensee;

               (c) The Seller has no knowledge of any  infringement  or improper
          use by any third party of the Proprietary  Rights, nor has the Seller,
          nor, to the Seller's Knowledge, the Seller's Licensee or any affiliate
          of either  instituted  any action,  suit or proceeding in which an act
          constituting  an  infringement  of any of the  Proprietary  Rights was
          alleged to have been committed by a third party;



                                      -13-



               (d)  Except as set forth in  Section  4.11(d)  of the  Disclosure
          Schedule, there are no licenses, sublicenses or agreements relating to
          (i) the use by third parties of the Proprietary Rights or (ii) the use
          by the Seller of the Proprietary  Rights,  and there is no prior right
          of any other  party or other  impediment  which  would  invalidate  or
          adversely affect any of the Proprietary Rights.

               (e) Set forth in Section 4.11(e) of the Disclosure  Schedule is a
          list of all  license,  royalty or  similar  agreements  entitling  the
          Seller to use any Trademarks or Copyrights of third parties.

          4.12.  Regulatory  Reports.  The  Seller  has,  and  to  the  Seller's
Knowledge,  the Seller's Licensee has filed all material reports,  registrations
and  statements,  together with any amendments  required to be made with respect
thereto, that they were required to file in respect of the Viractin Product Line
in the last five (5) year  period  with any  federal,  state,  local or  foreign
governmental,  quasi-governmental or regulatory department, authority or agency,
including,   without  limitation,  the  FDA  or  the  Federal  Trade  Commission
(hereinafter sometimes collectively,  the "Regulatory  Agencies"),  and has paid
all fees or  assessments  due and payable in  connection  therewith.  Except for
normal periodic  examinations  conducted by the applicable  Regulatory Agency in
the regular course of the Viractin Product Line, to the Seller's  Knowledge,  no
Regulatory  Agency  has  initiated  any  proceeding  or  investigation  into the
business or  operations  of the Viractin  Product Line in the last five (5) year
period,  nor  has  the  Seller  or the  Seller's  Licensee  initiated  any  such
proceeding.  To  the  Seller's  Knowledge,  there  is no  unresolved  violation,
criticism or exception  by any  Regulatory  Agency with respect to any report or
statement relating to an examination of the Viractin Product Line.

          4.13.  Agreements  with  Regulatory  Agencies.  Except as set forth in
Section  4.13 of the  Disclosure  Schedule,  the  Seller is not  subject  to any
cease-and-desist  or other order issued by, or a party to any written  agreement
or memorandum of  understanding  with,  any  Regulatory  Agency that  materially
restricts or may adversely impact the conduct of the Viractin Product Line.

          4.14.  Customers.  Section 4.14 of the Disclosure  Schedule contains a

          6.4.  Foreign Patent and Trademark  Assignments.  The Seller shall use
its best  efforts  to obtain  and record  all  appropriate  assignments  for any

or use  any  Buyer  Confidential  Information  for  its own  benefit  except  as
expressly   permitted   hereunder.   The  Seller  will  limit  access  to  Buyer

the extent such  disclosure  is  reasonably  necessary in filing or  prosecuting
patent  applications,  prosecuting  or defending  litigation  or complying  with

publish or disclose any information of the Seller which is proprietary,  a trade

                                      -18-

Agreement or its  representative,  or (iv) relates to the Viractin Product Line.
The  Buyer  acknowledges  that  there is not an  adequate  remedy at law for the
breach  of  this  Section  7.1 and  that,  in  addition  to any  other  remedies
available, injunctive relief may be granted for any such breach.

          7.2. Best Efforts.  The Buyer shall use its best efforts to consummate

                              RIGHT OF FIRST OFFER

          8.1.  Right of First Offer.  The Seller  agrees that,  for a period of
three (3) years following the Closing,  if the Seller develops any products that
are  intended  to be sold to  consumers  at  product  launch  without a doctor's
prescription  ("Over-the-Counter Products") which it wants to license or sell to
a third party,  then the Buyer shall have the first right to offer to license or
purchase such products from the Seller.

          8.2. Procedure of Right of First Offer.

               (a)  The  Seller  shall  notify  the  Buyer  in  writing  of  its
          intentions  regarding  the  license  or sale  of the  Over-the-Counter
          Product(s);

               (b) Within  thirty (30) days after  receipt of such  notice,  the
          Buyer shall submit a proposal in writing to the Seller  setting  forth
          the terms and conditions pursuant to which it is willing to license or
          purchase the product(s);

               (c) Seller  shall have thirty (30) days after  receipt of Buyer's
          proposal  to  reject  such  proposal,  which  it may  do at  its  sole
          discretion.  Such rejection must be delivered to the Buyer in writing.
          Failure to deliver such notice within the thirty (30) day period shall
          be deemed an acceptance by the Seller of the Buyer's



                                      -19-



          proposed  terms and  conditions.  If the Seller  rejects  the  Buyer's
          proposal,  the Seller can license or sell such  product(s)  to a third
          party  provided the material terms of such license or sale are no less
          favorable to the Seller as those proposed by the Buyer.

                      (i) upon or after the breach of any material  provision of

               thereof by the other party;

                      (ii)  if  a  court   of   competent   jurisdiction   or  a

               or (B) whose  failure to have  satisfied  the  conditions  to the
               other party's  obligations  under Section 9.2 (in the case of the
               Seller) or 9.3 (in the case of the Buyer), has been the cause of,

               obligation to any other party to this  Agreement  resulting  from
               such termination,  except (i) that the provisions of this Section
               10.2  shall  remain  in full  force and  effect,  and (ii) to the
               extent that any such  termination  results  from a breach by such
               party of any of its  representations,  warranties,  covenants  or
               agreements set forth in this Agreement, or any failure to satisfy
               the conditions to the other party's obligations under Section 9.2
               (in the case of Seller) or 9.3 (in the case of Buyer),  the other

Indemnified Party"), forever harmless from and against, and to promptly pay to a
Buyer  Indemnified  Party or reimburse a Buyer Indemnified Party for any and all
losses, damages, expenses (including,  without limitation,  court costs, amounts
paid in settlement,  judgments, reasonable attorneys' fees or other expenses for
investigating and defending, including, without limitation, those arising out of
the  enforcement  of this  Agreement),  suits,  actions,  claims,  deficiencies,
liabilities or obligations (collectively, the "Losses") sustained or incurred by
such Buyer  Indemnified  Party  relating to, caused by or resulting  directly or
indirectly from:

               (a) Any  misrepresentation  or breach of warranty,  or failure to
          fulfill  or  satisfy  any  covenant  or  agreement  made by the Seller
          contained  herein or in any certificate,  schedule,  document or other
          writing delivered by the Seller pursuant hereto;

               (b) Any  liability  of the Buyer for causes of action  arising in
          connection with the Viractin Product Line, the Purchased Assets or the
          Assumed  Liabilities based, in whole or in part, upon acts,  omissions
          or  events  which  occurred  on or prior to the  Transition  Date,  or
          relating to the period  prior to the  Transition  Date,  except as set
          forth in the Assignment and Assumption Agreement;

               (c) The Excluded Liabilities and Obligations; and

               (d) The  non-compliance  of  Seller  with the  provisions  of any
          applicable  bulk  sales act  governing  the  purchase  and sale of the
          Purchased Assets.

          11.3.  Indemnification of the Seller. From and after the Closing,  the
Buyer  agrees  to  indemnify,  defend  and save the  Seller  and its  directors,
officers, employees,



                                      -23-



owners,  agents and  affiliates  and their  successors  and assigns or heirs and
personal  representatives,  as the  case may be  (each,  a  "Seller  Indemnified
Party")  forever  harmless  from and  against,  and to promptly  pay to a Seller
Indemnified  Party or  reimburse  a Seller  Indemnified  Party for,  any and all
Losses  sustained  or incurred by such Seller  Indemnified  Party  relating  to,
caused by or resulting directly or indirectly from:

               (a) Any  misrepresentation  or breach of  warranty,  the  Assumed
          Liabilities or failure to fulfill or satisfy any covenant or agreement
          made by the Buyer contained  herein or in any  certificate,  schedule,
          document or other writing delivered by the Buyer pursuant hereto; and

               (b) Any  liability of the Seller for causes of action  arising in
          connection  with the  Viractin  Product Line or the  Purchased  Assets
          (including,  but not limited to,  Inventory,  promotional  allowances,
          product returns,  product  liability for any products  manufactured by
          the  Buyer,   and  Seller's   Licensee's   advertising,   display  and
          promotional  materials and customer lists) based upon acts,  omissions
          or events which occurred following the Transition Date, or relating to
          the period following the Transition Date.

          11.4.  Limitations  on  Indemnification.  Notwithstanding  anything in
Sections 11.2 and 11.3 to the contrary:

               (a) Neither the Seller nor the Buyer shall be entitled to recover
          any Losses for indemnification  under this Article XI unless and until
          the  aggregate  Losses  entitled to be  recovered by such party exceed
          Fifty Thousand Dollars ($50,000),  at which time the appropriate party
          shall be  entitled  to  recover  Losses  that are in  excess  of Fifty
          Thousand Dollars ($50,000);

               (b) In no event shall either party's indemnification  obligations
          exceed an aggregate  amount equal to the amount of the Purchase Price;
          and

               (c) The  limitations of Sections  11.4(a) and (b) shall not apply
          to any claim for Losses that are  determined  by a court of  competent
          jurisdiction in a proceeding from which no further appeal is permitted
          to be  taken to have  been  primarily  caused  by  fraud,  intentional
          misrepresentation or intentional breach.

          11.5.   Indemnification  Procedure  for  Third  Party  Claims  Against
Indemnified Parties.

               (a)  In the  event  that  subsequent  to the  Closing  any  Buyer
          Indemnified  Party or Seller  Indemnified Party (each, an "Indemnified
          Party")  receives  notice  of the  assertion  of any  claim  or of the
          commencement of any action,  suit or proceeding by any entity which is
          not a party to this Agreement (including, without



                                      -24-



          limitation,   any  governmental,   quasi-governmental   or  regulatory
          agencies) (a "Third Party Claim") against such Indemnified Party, with
          respect to which the Buyer or the Seller (the  "Indemnifying  Party"),
          as the case may be, are required to provide indemnification under this
          Agreement,  the Indemnified  Party shall promptly give written notice,
          together with a statement of any available  information regarding such
          claim (collectively, the "Third Party Indemnification Notice"), to the
          Indemnifying  Party  within  thirty  (30) days after  learning of such
          claim (or within such  shorter  time as may be  necessary  to give the
          Indemnifying Party a reasonable opportunity to respond to such claim).
          The Indemnifying  Party shall have the right, upon delivering  written
          notice to the Indemnified  Party (the "Defense  Notice") within thirty
          (30) days after  receipt  from an  Indemnified  Party of a Third Party
          Indemnification  Notice, to conduct, at the Indemnifying  Party's sole
          cost and  expense,  the defense  against such Third Party Claim in the
          Indemnifying  Party's own name,  or, if necessary,  in the name of the
          Indemnified Party; provided, however, that the Indemnified Party shall
          have the right to reasonably approve the defense counsel  representing
          the  Indemnifying  Party,  which  approval  shall not be  unreasonably
          withheld,  and in the  event  that  the  Indemnifying  Party  and  the
          Indemnified  Party cannot agree upon such counsel within ten (10) days
          after the Defense  Notice is  provided,  then the  Indemnifying  Party
          shall  propose an alternate  defense  counsel,  which shall be subject
          again to the  Indemnified  Party's  reasonable  approval in accordance
          with the terms hereof.

               (b) In the event that the  Indemnifying  Party shall fail to give
          the  Defense  Notice  within  the time and as  prescribed  by  Section
          11.5(a)  hereof,  then in any such event the  Indemnified  Party shall
          have the right to conduct  such  defense  in good  faith with  counsel
          reasonably  acceptable to the Indemnifying  Party, but the Indemnified
          Party shall be prohibited from compromising or settling any such claim
          without the prior written  consent of the  Indemnifying  Party,  which
          consent shall not be  unreasonably  withheld and shall be deemed given
          in the  absence  of  providing  the  Indemnified  Party with a written
          response  within  ten  (10)  days  of  any  request  therefor.  If the
          Indemnified  Party fails to diligently  defend such claim with counsel
          reasonably satisfactory to the Indemnifying Party, or settles any such
          claim  without the  Indemnifying  Party's prior  written  consent,  or
          otherwise  breaches  this  Article XI, the  Indemnified  Party will be
          liable for all costs,  expenses,  settlement  amounts or other  Losses
          paid or incurred in connection  therewith and the  Indemnifying  Party
          shall have no  obligation  to  indemnify  the  Indemnified  Party with
          respect to such claim.

               (c) In the  event  that the  Indemnifying  Party  does  deliver a
          Defense  Notice  and  thereby  elects to  conduct  the  defense of the
          subject Third Party Claim,  the Indemnified  Party will cooperate with
          and make  available  to the  Indemnifying  Party such  assistance  and
          materials as the Indemnifying Party may reasonably



                                      -25-



          request,  all at the sole cost and expense of the Indemnifying  Party.
          Regardless of which party  defends such claim,  the other party hereto
          shall have the right at its own cost and expense to participate in the
          defense  assisted  by counsel of its own  choosing.  The  Indemnifying
          Party  shall not enter into any  settlement  of any Third  Party Claim
          without the prior  written  consent of the  Indemnified  Party,  which
          consent shall not be unreasonably withheld. If a firm decision is made
          to settle a Third Party Claim,  which offer the Indemnifying  Party is
          permitted to settle under this Section  11.5(c),  and the Indemnifying
          Party  desires to accept  and agree to such  offer,  the  Indemnifying
          Party will give at least five (5) days'  prior  written  notice to the
          Indemnified  Party to that effect,  setting forth in reasonable detail
          the terms  and  conditions  of any such  settlement  (the  "Settlement
          Notice").  If the Indemnified  Party objects to such firm offer within
          ten (10)  calendar days after its receipt of such  Settlement  Notice,
          the  Indemnified  Party may  continue  to contest or defend such Third
          Party  Claim  and,  in  such  event,  the  maximum  liability  of  the
          Indemnifying  Party as to such Third  Party  Claim will not exceed the
          amount of such settlement  offer  described in the Settlement  Notice,
          plus costs and expenses paid or incurred by the  Indemnified  Party up
          to  the  point  such  Settlement  Notice  had  been  delivered.  If an
          Indemnified  Party  settles any Third  Party  Claim  without the prior
          written consent of the  Indemnifying  Party,  the  Indemnifying  Party
          shall have no obligation to indemnify the Indemnified Party under this
          Article XI with respect to such Third Party Claim.

               (d) Any judgment entered or settlement  agreed upon in the manner
          provided  herein shall be binding  upon the  Indemnifying  Party,  and
          shall be conclusively deemed to be an obligation with respect to which
          the Indemnified Party is entitled to prompt indemnification hereunder,
          subject  to the  Indemnifying  Party's  right to appeal an  appealable
          judgment or order. Such  indemnification  shall be required to be made
          no later than the tenth (10th) day  following  the  expiration  of any
          period in which an  appeal  may be taken,  and shall be  satisfied  by
          payment of the amount thereof in cash.

          11.6. Failure to Give Timely Third Party  Indemnification  Notice. Any
failure by an  Indemnified  Party to give a timely,  complete or accurate  Third
Party Indemnification  Notice as provided in this Article XI will not affect the
rights or obligations of any party hereunder except and only to the extent that,
as a result of such  failure,  any party  entitled  to receive  such Third Party
Indemnification  Notice was  deprived of its right to recover any payment  under
its applicable insurance coverage or was otherwise adversely affected or damaged
as a result of such failure to give a timely,  complete and accurate Third Party
Indemnification Notice.

          11.7.  Notice of  Claims.  In the case of a claim for  indemnification
under  Section  11.2 or  Section  11.3  hereof,  upon  determination  by a Buyer
Indemnified Party or a



                                      -26-



Seller  Indemnified  Party,  as  the  case  may  be,  that  it has a  claim  for
indemnification, the Indemnified Party shall deliver notice of such claim to the
Indemnifying  Party,  setting forth in reasonable detail the basis of such claim
for   indemnification   (each,   an   "Indemnification    Notice").   Upon   the
Indemnification  Notice  having been  received by the  Indemnifying  Party,  the
Indemnifying  Party  shall  have  thirty  (30)  days  in  which  to  notify  the
Indemnified Party in writing (the "Dispute Notice") that the amount of the claim
for indemnification is in dispute,  setting forth in reasonable detail the basis
of such  dispute.  In the  event  that a  Dispute  Notice  is not  given  to the
Indemnified  Party within the required thirty (30) day period,  the Indemnifying
Party shall be obligated to pay to the Indemnified Party the amount set forth in
the  Indemnification  Notice  within  sixty  (60)  days  after the date that the
Indemnification Notice had been received by the Indemnifying Party.

          In the event that a Dispute  Notice is timely given to an  Indemnified
Party,  the  parties  hereto  shall have  thirty  (30) days to resolve  any such
dispute.  In the event that such dispute is not resolved by such parties  within
such  period,  the parties  shall have the right to pursue all  available  legal
remedies to resolve such dispute.

                                  ARTICLE XII.

                                 NON-COMPETITION

          12.1. Non-Competition.  Commencing on the Closing Date and ending five
(5) years thereafter (the "Covered Period"),  the Seller agrees not to engage in
any  Competitive  Activity  (as  hereinafter  defined).  For  purposes  of  this
Agreement,  the term  "Competitive  Activity"  shall mean directly or indirectly
engaging  in the  business  of  licensing,  manufacturing,  distributing  and/or
selling  any  products  and  researching  and  developing  any  Over-the-Counter
Products for the treatment of cold sores and fever blisters.

          12.2.  Injunctive Relief. The Seller  acknowledges and agrees that the
Buyer is engaged in a highly  competitive  business and that the  protections of
the Buyer set forth in this Article XII are fair and reasonable and are of vital
concern to the Buyer.  Further, the Seller acknowledges and agrees that monetary
damages for any violation of this Article XII will not adequately compensate the
Buyer with respect to any such violation. Therefore, in the event of a breach by
the Seller of this Article  XII, the Buyer shall be entitled to institute  legal
proceedings to obtain damages for any such breach and/or to enforce the specific
performance  of this Article XII by the Seller and to enjoin the Seller from any
further violations.



                                      -27-



                                  ARTICLE XIII.

                            MISCELLANEOUS PROVISIONS

          13.1.  Waiver.  No  provision  of this  Agreement  will be  waived  or
discharged  by any  act,  omission  or  knowledge  of a party or its  agents  or
employees,  except by a written instrument expressly waiving or discharging such
provision  signed by a duly authorized  representative  of the waiving party. No
waiver  by either  party  hereto  at any time of any  breach by the other  party
hereto of, or compliance  with,  any condition or provision of this Agreement to
be  performed  by such  other  party  shall be  deemed a waiver  of  similar  or
dissimilar  provisions  or  conditions at the same or at any prior or subsequent
time.

          13.2.   Amendment;   Modification.   No  amendment,   modification  or
supplement of any provision of this Agreement will be valid or effective  unless
made in writing and signed by an authorized representative of each party.

          13.3.  Invalidity.  If  any  provision  of  this  Agreement  shall  be
determined by any court of competent jurisdiction to be unenforceable or invalid
to any extent,  the remainder of this Agreement  shall not be affected  thereby,
and this  Agreement  shall be construed to the fullest  extent  possible to give
effect to the intentions of the provision found unenforceable or invalid.

          13.4.  Parties in Interest.  This Agreement  shall be binding upon and

remedies of any nature whatsoever under or by reason of this Agreement.

relating to its performance of its respective  obligations  hereunder,  (b) to a
wholly  owned  subsidiary   provided  it  guarantees  the  obligations  of  such
subsidiary  or (c) in the event of its  merger  or  consolidation  with  another
company at any time during the term of this Agreement.  The Buyer may assign all
or any part of its rights and  obligations  hereunder  to a person or entity who

with the Buyer (in each case by ownership of at least fifty percent (50%) of the
outstanding  voting securities of a corporation or comparable equity interest in
any other type of entity,  or by contract or other  arrangement).  Any purported
assignment  in  violation of this  Section  13.11 shall be void.  The rights and
obligations  of the parties under this Agreement will be binding upon the heirs,
successors  and  permitted  assigns  of the  parties  and  the  name  of a party
appearing herein will be deemed to include the names of such party's  successors
and  permitted  assigns to the extent  necessary to carry out the intent of this
Agreement.

          13.12.  Publicity.  No party shall  issue any press  release or public
announcement  of any  kind  concerning  the  transactions  contemplated  by this
Agreement without the prior written consent of the other parties hereto,  except
as may be  required  by law or by the  rules of any  stock  exchange,  and if so
required,  the parties shall,  to the extent that it is reasonably  practicable,
consult with each other prior to such  publicity.  The parties agree to issue an
announcement  following the Closing in form and content  satisfactory  to all of
the parties hereto.
