(1)   BASIS OF PRESENTATION

      The unaudited condensed  consolidated financial statements included herein
have been prepared by the Company,  pursuant to the rules and regulations of the
Securities  and Exchange  Commission and in accordance  with generally  accepted
accounting  principles.  Certain information and footnote  disclosures  normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles have been condensed or omitted pursuant to such rules and
regulations.  These unaudited condensed consolidated financial statements should
be read in conjunction  with the Company's 1997 audited  consolidated  financial
statements and footnotes.

      The accompanying  unaudited condensed  consolidated  financial  statements
include the results of the Company and its wholly-owned  subsidiary  (CollaGenex
International,  Ltd.).  All  intercompany  accounts and  transactions  have been
eliminated.

      In the opinion of the Company's  management,  the  accompanying  unaudited
condensed  consolidated  financial  statements  have  been  prepared  on a basis
substantially  consistent with the audited consolidated financial statements and
contain adjustments, all of which are of a normal recurring nature, necessary to
present  fairly the Company's  financial  position as of September 30, 1998, its
results of operations for the three and nine months ended September 30, 1997 and
1998 and for the period January 10, 1992  (inception) to September 30, 1998, and
its cash flows for the nine months ended September 30, 1997 and 1998 and for the
period January 10, 1992  (inception) to September 30, 1998.  Interim results are
not necessarily indicative of results anticipated for the full fiscal year.


(2)   NEW ACCOUNTING PRONOUNCEMENTS

      Effective  January 1, 1998,  the Company  adopted  Statement  of Financial
Accounting Standards No. 130 "Reporting Comprehensive Income" ("SFAS 130"). SFAS
130 requires that all items defined as comprehensive  income,  including changes
in the amounts of certain items such as foreign currency translation adjustments
and  gains  and  losses  on  certain  securities,  be  shown as a  component  of
comprehensive income in a financial  statement.  The adoption of SFAS 130 had no
effect on the Company's unaudited condensed  consolidated  financial  statements
contained herein, as the Company had no items of comprehensive income during any
period presented therein.

      Statement of Financial  Accounting Standards No. 128, "Earnings Per Share"
("SFAS  128"),  was adopted by the Company on December 31, 1997.  In  accordance
with SFAS 128, all earnings per share data for periods prior to adoption  should
be  restated  to  conform  to the  new  standard.  There  was no  change  in the
previously  reported  net loss per share for the three  months  and nine  months
ended September 30, 1997 as computed under SFAS 128.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


OVERVIEW

      CollaGenex   Pharmaceuticals,   Inc.   (the   "Company")  is  an  emerging
pharmaceutical company focused on developing innovative medial therapies for the
treatment  of  diseases  involving  the  destruction  of the  body's  connective
tissues.  The Company's  core  technology  involves  inhibiting  the activity of
certain  enzymes that degrade the connective  tissues of the body. The Company's
first  product,  Periostat(R),  was approved by the United  States Food and Drug
Administration  (the  "FDA")  in  September  1998  for the  treatment  of  adult
periodontitis,  which  affects  approximately  67  million  people in the United
States and is the  leading  cause of tooth  loss.  Periostat  is a  prescription
pharmaceutical  capsule  indicated  as an adjunct to scaling  and root  planning
("SRP"),  the most prevalent therapy for  periodontitis,  to promote  attachment
level gain and to reduce  pocket  depth in  patients  with adult  periodontitis.
Periostat will be shipped to wholesalers by mid-November and should be available
to patients in the United States no later than  December 1, 1998.  Substantially
all  of  the  Company's  expenditures  to  date  have  been  for  pharmaceutical
development activities,  including the development of Periostat, and general and
administrative expenses.

      Since  inception,  the  Company  has  operated  with a  minimal  number of
employees.  Substantially all pharmaceutical  development activities,  including
clinical trials, have been contracted to independent contract research and other
organizations.  Following  approval from the FDA to market  Periostat within the
United States,  the Company has begun and  anticipates  that it will continue to
significantly increase the number of its employees over the next year, primarily
in sales and marketing  and general and  administrative  areas.  There can be no
assurance,  however,  that the Company will successfully market Periostat in the
United States or elsewhere.

      The  Company has  incurred  losses  each year since  inception  and had an
accumulated  deficit of $34.6 million at September 30, 1998. The Company expects
to continue to incur losses in the foreseeable future from expenditures on sales
and marketing, manufacturing, drug development and administrative activities.

      Statements contained or incorporated by reference in this Quarterly Report
on Form  10-Q  that  are not  based  on  historical  fact  are  "forward-looking
statements" within the meaning of Section 21E of the Securities  Exchange Act of
1934,  as amended.  Forward-looking  statements  may be identified by the use of
forward-looking   terminology  such  as  "may,"  "will,"  "expect,"  "estimate,"
"anticipate,"  "continue,"  or similar  terms,  variations  of such terms or the
negative of those terms. This Form 10-Q contains forward-looking statements that
involve risks and uncertainties.  The Company's  business of selling,  marketing
and  developing  pharmaceutical  products is subject to a number of  significant
risks, including risks relating to the implementation of the Company's sales and
marketing plans for Periostat, risks inherent in research and

                                       8

<PAGE>

development  activities,  risks associated with conducting  business in a highly
regulated environment,  risks relating to the Company's Year 2000 compliance and
the Year 2000  compliance of the Company's  vendors,  suppliers,  manufacturers,
distributors,  marketing  partners  and certain  other  parties and  uncertainty
relating to clinical  trials of products under  development.  The success of the
Company  depends to a large  degree upon the market  acceptance  of Periostat by
periodontists,  dental practitioners,  other health care providers, patients and
insurance  companies.  Other than  Periostat,  which has been FDA  approved  for
marketing  in the  United  States,  there  can be no  assurance  that any of the
Company's other product candidates will be approved by any regulatory  authority
for marketing in any jurisdiction  or, if approved,  that any such products will
be successfully  commercialized by the Company. The Company's actual results may
differ materially from the results discussed in the  forward-looking  statements
contained herein.


RESULTS OF OPERATIONS

      From its founding through  September 30, 1998, the Company had no revenues
from sales of its own products.  The Company expects to have Periostat available
by prescription no later than December 1, 1998.  Operating  expenses  consist of
research  and  development  expenses  and general and  administrative  expenses.
Research and development  expenses  consist  primarily of funds paid to contract
research  organizations  for the  provision of services and  materials  for drug
development and clinical  trials.  General and  administrative  expenses consist
primarily of personnel salaries and benefits,  professional and consulting fees,
insurance,  facilities and general office expenses.  Following approval from the
FDA in  September  1998 to  market  Periostat  within  the  United  States,  the
Company's  sales and  marketing  expenses have begun to increase and the Company
believes that its general and administrative  expenses will continue to increase
during the next several years due to the  expansion of the Company's  commercial
infrastructure, primarily in sales and marketing.

      The Company  earned  $8,000 and $1,000 in contract  revenues  for the nine
months and the three months ended September 30, 1998, respectively,  and did not
recognize  contract  revenues in either of the comparable year earlier  periods.
The Company earned an aggregate of $400,000 in licensing revenue during the nine
month  and three  month  periods  ending  September  30,  1998,  compared  to an
aggregate of $300,000 for the nine months ended  September 30, 1997.  There were
no licensing revenues recorded during the three months ended September 30, 1997.
Licensing revenues achieved in 1998 were attributable to the Company's licensing
arrangement with Laboratoires Pharmascience S.A. ("Laboratoires  Pharmascience")
executed in July 1998.  Licensing revenues achieved in 1997 were attributable to
the Company's licensing arrangement with Boehringer Mannheim Italia.

      Research  and  development  expenses  increased  $572,000,  or 15.8%,  and
$247,000,  or 15.9%,  respectively,  for the nine months and three  months ended
September 30, 1998,  over the comparable  year earlier  periods.  Such increases
resulted  primarily  from  expenses  relating to a Phase 3b  clinical  trial for
Periostat  initiated during the first quarter of 1998, the initiation of certain
pre-clinical studies for Nephrostat(R), the Company's compound for the treatment
of  complications  of diabetes,  and  consulting and product  registration  fees
associated  with  obtaining

                                       9

<PAGE>


regulatory approval for Periostat in the United Kingdom. The Company anticipates
that the results from the Phase 3b clinical trial, if favorable, will be used to
support marketing  activities for Periostat.  There can be no assurance that the
Company will successfully market Periostat in the future.

      General and administrative  expenses increased $1.1 million, or 25.8%, and
$617,000,  or 34.2%,  respectively,  for the nine months and three  months ended
September 30, 1998,  over the comparable  year earlier  periods.  Such increases
were primarily due to the Company's  pre-launch  marketing activities related to
Periostat  and  sales and  marketing  efforts  related  to  certain  contractual
marketing arrangements entered into during 1997.

      Interest income  decreased  $171,000,  or 17.5%,  and $128,000,  or 35.8%,
respectively,  for the nine months and three  months ended  September  30, 1998,
over the  comparable  year earlier  periods.  Such  decreases  were due to lower
balances  in cash and  short-term  investments  as a result of normal  operating
activities  since the  Company's  follow-on  public  offering of Common Stock in
April 1997.


LIQUIDITY AND CAPITAL RESOURCES

      Since its origin in January 1992,  the Company has financed its operations
through  private  placements  of preferred  stock and common  stock,  an initial
public  offering  of  2,000,000  shares of common  stock,  which  generated  net
proceeds to the Company of approximately  $18.0 million after  underwriting fees
and related  expenses,  and a subsequent  public offering of 1,000,000 shares of
common stock, which generated net proceeds to the Company of approximately $11.6
million after underwriting fees and related expenses. At September 30, 1998, the
Company had cash, cash  equivalents and short-term  investments of approximately
$15.3  million,  a decrease of $7.5  million from the $22.8  million  balance at
December 31, 1997.  In accordance  with  investment  guidelines  approved by the
Company's Board of Directors,  cash balances in excess of those required to fund
operations  have been  invested  in  short-term  U.S.  Treasury  securities  and
commercial paper with a credit rating no lower than A1/P1. The Company's working
capital of $12.5  million at  September  30,  1998  reflected a decrease of $8.1
million in working capital from December 31, 1997.

      The Company had no debt or capital leases outstanding (other than accounts
payable and accrued  expenses) at  September  30,  1998.  On June 26, 1997,  the
Company  entered into a credit  arrangement  consisting of a $5,000,000  line of
credit (the "LOC") to support the future  working  capital needs of the Company.
The LOC will be unsecured as long as the Company's cash and investment  balances
maintained  with the lender or an  affiliate of the lender equal or exceed $10.0
million. At the Company's option, the LOC will bear interest at either the prime
rate  charged by the lender or LIBOR plus 2.15%.  The LOC is  terminable  by the
lender at any time.  No balance was  outstanding  under the LOC at September 30,
1998.

     The  Company   anticipates  that  its  existing  working  capital  will  be
sufficient to fund the Company's  operations  through at least 1998. The Company
is considering  capital  raising efforts to satisfy  additional  working capital
requirements.  The Company's future capital requirements and the adequacy of its
available funds will depend on many factors, including the size and scope

                                       10

<PAGE>


of the Company's sales and marketing  activities with respect to Periostat,  for
which the FDA granted approval to the Company in September 1998 to market within
the United States, the terms of agreements entered into with corporate partners,
if any,  and the  results of  research  and  development  and  pre-clinical  and
clinical studies for other  applications of the Company's core technology.  Over
the long term, the Company's  liquidity is dependent on market acceptance of its
products and technology.


Year 2000 Compliance

      The Company is presently  assessing its state of readiness with respect to
the Year 2000  problem.  The  Company  has been  informed  by the  vendor of its
internal  accounting,  management and financial reporting  applications that the
current version of such software is not presently Year 2000 compliant.  In early
1999, the Company expects to install an upgraded  version of such software which
the  vendor  has  represented  is  Year  2000  compliant.  Management  does  not
anticipate that Year 2000 issues will have a significant  impact on its internal
accounting,  management  or  financial  reporting  or  result  in a  significant
commitment  of  resources  to  resolve  potential   problems  with  its  systems
associated with this event. The Company is also presently  conducting  inquiries
of its outside  vendors,  suppliers,  manufacturers,  distributors and marketing
partners to assess their respective Year 2000 readiness.  Upon completion of the
foregoing,  the Company will be able to estimate the financial  impact,  if any,
should  such  parties  fail to be  Year  2000  compliant.  The  Company  has not
developed a contingency plan with respect to Year 2000 issues should they arise.


European Monetary Union

      On January 1, 1999, eleven of the fifteen member countries of the European
Union are scheduled to set fixed  conversion rates between their existing legacy
currencies and the euro. At such time, these participating countries have agreed
to adopt the euro as their  common  legal  currency.  The  eleven  participating
countries will issue  sovereign debt  exclusively in euro and will  redenominate
outstanding  sovereign  debt. The legacy  currencies will continue to be used as
legal tender through January 1, 2002, at which point the legacy  currencies will
be canceled and euro bills and coins will be used for cash  transactions  in the
participating countries.

      The Company does not denominate its international  licensing agreements in
foreign  currencies.  The  Company  currently  does  not  believe  that the euro
conversion will have a material impact on the Company's results of operations or
financial condition.

Item 5.  Other Information

         New Drug Application

      On October 1, 1998,  the Company  announced that the FDA had granted final
approval to the  Company to market  Periostat  within the United  States for the
treatment of adult  periodontitis.  Periostat is a  prescription  pharmaceutical
capsule  indicated  as an  adjunct  to  scaling  and root  planning  to  promote
attachment  level  gain and to  reduce  pocket  depth  in  patients  with  adult
periodontitis.  The Company expects to have Periostat  available by prescription
no later than December 1, 1998.  There can be no assurance that the Company will
successfully market Periostat in the United States or elsewhere.

         Licensing Agreement

      The Company executed a licensing agreement with Laboratoires Pharmascience
in July 1998 pursuant to which  Laboratoires  Pharmascience will manufacture and
distribute Periostat in France, Morocco, Algeria, Tunisia and other countries of
French speaking Africa.  Pursuant to the agreement,  Laboratoires  Pharmascience
paid the Company a $400,000  non-refundable  license  fee on August 4, 1998.  In
addition,  Laboratoires  Pharmascience  agreed to pay  additional  fees upon the
achievement of future milestones and royalties upon future sales of Periostat in
such  areas.  The  Company  has agreed to use its  reasonable  efforts to obtain
applicable marketing authorization for Periostat in the licensing territory. The
non-refundable  license  fee was  recorded  as  licensing  revenue  in the third
quarter of 1998.

         Co-Promotion Agreement

      The Company  executed a  Co-Promotion  Agreement with  SmithKline  Beecham
Consumer Healthcare,  L.P.  ("SmithKline") in October 1998 pursuant to which the
Company  will  promote   SmithKline's   Denavir(R)   product,  an  FDA  approved
prescription pharmaceutical for the treatment of recurrent cold sores in healthy
adults,  to the United  States  dental  community.  The  agreement  provides for
certain payments by SmithKline to the Company upon future sales of Denavir.

         Distribution Services Agreement

      The  Company  executed  a  Distribution   Services   Agreement  with  Cord
Logistics, Inc. ("Cord") in November 1998 pursuant to which Cord will act as the
Company's  exclusive  distribution  agent for Periostat in the United States and
Puerto Rico.  Under this  agreement,  Cord will  warehouse and ship Periostat to
wholesalers from its distribution facility in Tennessee for a pre-negotiated fee
and will provide various financial and other support services to the Company.

        be complied with. Other than as defined in Clause 12 hereof, the failure
        of a manufacturing  source to supply the Products to Licensee  resulting
        in Licensee  having an out of stock situation that lasts up to three (3)

        CollaGenex.

        obtain the applicable  marketing  authorisations for the Products in the
        Territory from the relevant  authorities,  save where such  applications
        are  made,  by  prior  agreement,  by  Licensee;  and to  maintain  such
        marketing  authorisations  during  the  term  hereof  and any  extension
        hereto. CollaGenex shall be the owner and party of record sponsoring all
        submissions to the regulatory  authorities in the Territory with respect
        to the Products and to the Improved  Products.  CollaGenex  will furnish
        Licensee  with all Know-how and relevant  documentation  required by the
        regulatory  authorities  in the Territory to allow Licensee to use, sell
        and distribute the Products in the Territory.

        Upon the request of CollaGenex,  Licensee shall provide reasonable local
        technical and local market knowledge assistance to CollaGenex and/or any
        professional  advisors to CollaGenex which shall include, but may not be

        organisations;    in   obtaining   and    maintaining    the   marketing
        authorisations.

        efforts  to  furnish   Licensee  with  all  commercial   information  in
        CollaGenex's  possession  which may include,  but may not be limited to;
        market  research  data;   marketing  plans;  sales  plans;   promotional
        activities;  conferences;  seminars;  exhibitions  and the like in which
        CollaGenex   and/or   Affiliates  of  CollaGenex   and/or  licensees  of
        CollaGenex  outside of the Territory  may be involved or concerned,  and
        relating to the Products, in English; within a reasonable period of such
        commercial  information  becoming  available
<PAGE>

        to CollaGenex  and which may reasonably be required by Licensee in order
        for Licensee to fulfil its obligations  hereunder.  Licensee understands
        and agrees that such commercial information may constitute  Confidential
        Information  hereunder.  Licensee shall be responsible for obtaining all
        local  commercial  and pricing  authorisations  for the marketing of the
        Products in the Territory in accordance with the regulations  pertaining
        to the Territory and shall keep CollaGenex or an Affiliate of CollaGenex
        fully   informed  with  regard  to  progress  in  obtaining  such  local
        commercial and pricing authorisations.

3.2.    REPORTS  AND  PAYMENTS.  Payments  pursuant to Clauses  3.1.1.,  3.1.2.,
        3.1.3.  and  3.1.4.  inclusive  hereof  will  be  paid  by  Licensee  to
        CollaGenex,  by a method  designated by  CollaGenex,  within thirty (30)
        days of the milestone or other event specified therein.

        No payment  shall be due in  accordance  with the  provisions  of Clause
        3.1.1.  hereof if, within thirty (30) days of the effective date of this
        Agreement,  the parties have met with an Expert Rapporteur to the French
        Medicines  Agency and have  mutually  agreed that there is no reasonable
        probability  of  acceptance  by  the  French   Medicines  Agency  of  an
        application for a marketing  authorisation  in France and this Agreement
        shall immediately terminate save as for the provisions of this Agreement
        that shall survive termination.

        Licensee undertakes and agrees to notify CollaGenex,  in writing, within
        seven (7) days of the  commercial  and pricing  approvals  specified  in
        Clause 3.1.4. hereof being obtained. Payments pursuant to Clauses 3.1.5.
        and  3.1.6.  hereof,  as  applicable,  will  be  paid,  as  directed  by
        CollaGenex,  within  fifteen  (15) days  after the end of each  calendar
        quarter  during the term hereof or any extension  hereto with respect to
        the  applicable  Net Sales  made by  Licensee  and/or any  Affiliate  of
        Licensee during each calendar quarter.

        With each quarterly  payment,  Licensee will provide  CollaGenex  with a
        written report stating the actual Net Sales made by the Licensee  and/or
        any  Affiliate of Licensee  during such prior  calendar  quarter and the
        amount of royalties due to CollaGenex thereon pursuant to this Clause 3.
        The  minimum  payment  shown in Clause  10.3.  hereof  shall be  payable
        annually after calculation against the actual royalties remitted and any
        shortfall remitted,  in a manner to be designated by CollaGenex,  within
        thirty (30) days of the end of such quarter.

        The parties have the option to mutually agree,  at an appropriate  time,
        for  royalties  to be remitted in the European  currency  "the Euro" (or
        such other  designation as may be given to a common  European  currency)
        provided that the parties have agreed an exchange  rate,  subject to the
        terms above,  of the Euro against the  currency in which  royalties  had
        been previously remitted or would have been remitted.

3.3.    RECORDING AND INSPECTION. Licensee agrees that for a period of three (3)
        years after delivery of each report referred to in Clause 3.2. above, it
        shall  keep at its  principal  place of  business  complete  records  of
        applicable  Net Sales  received  by  Licensee  and/or any  Affiliate  of
        Licensee  and all other  information  necessary  to permit  Licensee  to
        verify  the  accuracy  of the  calculations  of Net  Sales,  and to make
        regular entries in such records at its earliest business convenience for
        the purpose of determining the Net Sales as defined herein.

        For  the  sole  purpose  of  verifying  Licensee's  performance  of  its
        obligations to make payments hereunder,  CollaGenex,  solely through its
        certified  public  accountant  or authorised  representative  thereof or
        other independent  third party designee,  will have the right to examine
        Licensee's  records  reflecting  such Net Sales  and other  information,
        provided that such  examination is made within three (3) years after the
        close of the
<PAGE>
        calendar year in respect of which Licensee's records are being examined,
        conducted  within  Licensee's  normal business hours,  made after thirty
        (30) days advance written notice to Licensee and limited to no more than
        one   examination  in  any  one  calendar  year.  The  results  of  such
        examination  shall be made available to both parties.  CollaGenex  shall
        bear the full cost of the performance of such  examination,  unless such
        examination discloses a variance of more than two per cent (2%) from the
        amount of the  original  report or  payment  calculation.  In such case,
        Licensee shall bear the full cost of the performance of such examination
        and Licensee shall promptly pay to CollaGenex any variance  disclosed in
        such examination.

3.4.    CURRENCY OF PAYMENT. All payments shall be made in United States dollars
        (US$).  Royalty  payments in United States  dollars  pursuant to Clauses
        3.1.5.  and 3.1.6 hereof shall be  translated at the rate of exchange at
        which  United  States  dollars  are  listed in the Wall  Street  Journal
        against the French franc, or, as applicable,  the Euro; at an average of
        the  daily  rate  during  the  calendar  quarter  in which Net Sales are
        received by Licensee or by an Affiliate of Licensee.

3.5.    METHOD OF PAYMENT.  All payments  shall be made in  accordance  with the
        provisions  of  Clause  3.2.  hereof by Direct  Wire  Transfer  or other
        generally accepted method of Bank to Bank currency transfer, all charges
        to account of drawer,  to an account of  CollaGenex's  definition and at
        the sole discretion of CollaGenex.

4.      TRADEMARK MATTERS

4.1.    Licensee shall be permitted to use the trade mark  "Periostat" in styles
        and formats to be  designated  solely by CollaGenex  for the  marketing,
        selling, advertising and distribution of the Products in the Territory.

4.2.    Registration of the trade mark, maintenance and protection of such trade
        mark,   and  all   costs   associated   therewith   shall  be  the  sole
        responsibility of CollaGenex.

4.3.    Licensee shall promptly notify CollaGenex,  in writing,  in the event of
        any  infringement  of the trade mark, or potential  infringement  of the
        trade mark, in the Territory  coming to its attention,  or the attention
        of one of its  Affiliates,  and shall assist  CollaGenex,  to the extent
        requested and/or directed by CollaGenex, in protecting the trade mark in
        the Territory.

8.3.    TERMINATION RELATED TO REGISTRATION.  The parties agree that gaining the
        necessary marketing  authorisation for the Products in France is pivotal
        to this Agreement. CollaGenex agrees to keep Licensee informed regarding

        shall be liable to the other in the event of delays directly relating to
        the actions of a regulatory  authority  and neither party shall have the

        distribute  the Products in the  Territory  under this  Agreement at any
        time  upon               *                    days  written   notice  to
        CollaGenex.  Such reversion  shall be free of any continuing lien on, or
        grant of any right or  interest  in, the  Products  or the  Confidential
        Information.  In the  event of such  termination,  no  further  payments
        relating to the  milestones  specified  in Clauses  3.1.2.,  3.1.3.  and
        3.1.4. hereof relating to the Products shall accrue or be due under this
        Agreement   subsequent  to  the  effective  date  of  such  termination;
        provided,  however,  that Licensee shall pay to CollaGenex any royalties
        accrued on Net Sales prior to the effective  date of the  termination of
        the License under this Clause 8.4.

8.5.    TERMINATION BY FAILURE OF LICENSEE TO MARKET.  CollaGenex shall have the
        right to terminate this Agreement  should  Licensee fail to initiate and
        maintain for the term of this Agreement an active  marketing,  sales and
        distribution  programme  and  launch the  Product  in France  within    
                   *             days of written advice from CollaGenex that the
        marketing  authorisation  has been granted  and/or  written  advice from
        Licensee to CollaGenex in accordance with Clause 3.1.4.  hereof that the
        reimbursement

     Securities and Exchange Commission.

<PAGE>

        received official  notification that reimbursement for the Products will
        not be granted, whichever shall be the later.

8.6.    BREACH OF MATERIAL  OBLIGATIONS.  Failure by either party to comply with
        any of the  material  obligations  contained  in  this  Agreement  shall
        entitle  the  other  party  to  give  to the  party  in  default  notice
        specifying  the nature of the default and requiring such party to remedy
        such  default.  If such default is not remedied  within ninety (90) days
        (or, if the default cannot be remedied within such ninety day period and
        the party in default does not commence and diligently  continue  actions
        to remedy such default), the notifying party shall be entitled,  without
        prejudice to any of its other rights  conferred on it by this Agreement,
        to all remedies available to it by law or in equity, including,  without
        limitation, the termination of this Agreement.

8.7.    INSOLVENCY  OR  BANKRUPTCY.  Either  party may, in addition to any other
        remedies  available to it by law or in equity,  terminate this Agreement
        by written  notice to the other party in the event the other party shall
        have become insolvent or bankrupt,  or shall have made an assignment for
        the  benefit of its  creditors,  or there  shall have been  appointed  a
        trustee or receiver of the other party for all or a substantial  part of
        its  property,  or any case or proceeding  shall have been  commenced or
        other  action  taken by or  against  the other  party in  bankruptcy  or
        seeking   re-organisation,    liquidation,    dissolution,    winding-up
        arrangement,  composition  or  re-adjustment  of its debts or any relief
        under any bankruptcy,  insolvency,  re-organisation or other similar act
        or law of any  jurisdiction  now or hereafter in effect,  or there shall
        have been issued a warrant of  attachment,  execution  or  distraint  or
        similar  process  against any  substantial  part of the  property of the
        other party, and any such event shall have continued for sixty (60) days
        undismissed, unbonded and undischarged.

8.8.    RIGHT TO SELL STOCK ON HAND. Upon the termination of the License granted
        hereunder  for any  reason  other  than a failure  to remedy a  material
        breach of this  Agreement by Licensee,  Licensee shall have the right to
        complete all work in progress and for one year (or such longer period as
        the parties may reasonably and mutually  agree) to dispose of all of the
        Products then on hand by way of normal trade sales in the Territory, and
        royalties  shall be paid to CollaGenex with respect to such sales of the
        Products as though such License had not terminated or expired.

8.9.    EFFECT OF  TERMINATION.  In the event of termination of this  Agreement,
        except as otherwise  provided for herein; all rights to the Products and
        the  Confidential  Information  shall revert to CollaGenex  who shall be
        free to  develop,  license or  otherwise  exploit the  Products  and the
        Confidential  Information in the Territory as it deems  appropriate  and
        Licensee  shall (a) take  whatever  steps are  reasonably  necessary and
        appropriate  to revert to CollaGenex  all rights in the Products and the
        Confidential  Information  in the Territory and (b) return to CollaGenex
        all   information   relating  to  the  Products  and  the   Confidential
        Information  without retaining any copies or extracts  therefrom save as
        may be required  to  identify  the  obligations  of Licensee  under this
        Agreement  and  (c)  make  no  further  use of 
<PAGE>

        any of the  Confidential  Information  and (d) take  whatever  steps are
        reasonably  necessary and  appropriate  to transfer to CollaGenex or its
        designees  all  submissions  to  regulatory  authorities  (or  any  part
        thereof) in the Territory and (e) to immediately  cease to use the Trade
        Marks and in the event that  (contrary to the  intention of  CollaGenex)
        the  Licensee  has  acquired  any  rights in or over the trade  marks to
        transfer  the  same,  unencumbered,  to  CollaGenex  and  (f) to take no
        actions that would in any way have a negative effect on the sales of the
        Products in the Territory.

8.10.   SURVIVING RIGHTS.  Any termination under this Agreement shall be without
        prejudice to the rights and remedies of either party with respect to any
        provisions  of this  Agreement or arising out of breaches  prior to such
        termination  and  shall  not  relieve  either  of  the  parties  of  any
        obligation or liability  accrued  hereunder  prior to such  termination,
        including,  without limitation,  indemnity  obligations,  nor rescind or
        give rise to any right to rescind  anything done or any payments made or
        other   consideration   given  hereunder  prior  to  the  time  of  such
        termination  and shall not affect in any  manner  any  vested  rights of
        either party arising out of this Agreement prior to such termination.

        part of this  Agreement  as  Appendix  II,  for each of the three  years
        following  the  date of first  Commercial  Sale of the  Products  in the
        Territory  and this Schedule II will be updated by Licensee on an annual
        basis,  in accordance  with  Licensee's own business and budget planning
        process,  and such updates will include the  following  years so that at

        Products in the  Territory.  Such  forecasts  shall  reasonably  reflect
        actual historical  Commercial Sales and Commercial Sales trends, if any.
        Prior to first  Commercial  Sale,  any  changes to  Schedule II shall be
        subject to the  approval of  CollaGenex.  Such  schedule,  in the agreed
        format of Appendix II, shall be furnished by Licensee to  CollaGenex  by
        no later than the 1st January of each calendar year for the term of this
        Agreement and any extension hereto.

        month period from date of first  Commercial  Sale of the Products in the
        Territory.  In the second  twelve  (12) month  period from date of first
        Commercial   Sale  of  the  Products  in  the  Territory,   the  Minimum
        Performance  as defined  in this  Clause  10.3.  shall be       *       
              of the most recent  forecast for such period.  Commencing with the
        third twelve (12) month period from the date of first Commercial Sale of
        the  Products in the  Territory,  and for each twelve (12) month  period
        thereafter,  a sum equivalent to            *                of the most
        recent  forecast  for  such  period  shall  be  agreed  as  the  Minimum
        Performance  of  Licensee  for such  period,  hereinafter  "the  Minimum
        Performance".

        In the event of the actual  Net Sales of  Licensee,  as defined  herein,
        being less than the Minimum  Performance,  then Licensee  shall have the
        right to pay the royalty as defined in Clauses 3.1.5. and 3.1.6.  hereof
        based on the Minimum  Performance  as defined  herein in order to retain
        its rights under this Agreement, failing which CollaGenex shall have the

                  Adverse  Experiences  (as defined in Paragraph  8.1),  and the
                  reporting thereof to SB, in accordance with the procedures and
                  timelines set out in Article 8.

3.3      SAMPLES

         3.3.1    Samples  of  DENAVIR(R)  to be  used  by  COMPANY  under  this
                  AGREEMENT  shall be sent to  COMPANY or its  designees  at the
                  expense  (internally  charged standard unit cost plus shipping
                  and  handling)  of SB. The  storage and  distribution  of such
                  samples to professional  representatives shall be at COMPANY's
                  expense.

         3.3.2    COMPANY shall receive amounts of such samples as determined by

                  the extent  possible,  with both SB's and  COMPANY's  shipping
                  schedules.   SB  shall   periodically   provide  COMPANY  with
                  guidelines  concerning the  distribution  of samples to TARGET
                  PRESCRIBERS.

         3.3.3    COMPANY  warrants  and  represents  that it  shall  establish,
                  maintain  and  adhere to  written  procedures  to assure  that
                  COMPANY's  receipt,  storage and distribution of samples,  and
                  all of its  professional  sales  representatives  to whom such
                  samples are  distributed,  comply with all requirements of the
                  AGENCIES including the Prescription Drug Marketing Act of 1987
                  (as such may be subsequently  modified), as well as reasonable
                  compliance  with  the  U.S.  Food  and  Drug  Administration's
                  proposed regulations,  published at 59 Fed. Reg. p11842, March
                  14,  1994.  Specifically,  such  procedures  shall  include  a
                  requirement  that  COMPANY  shall notify SB  immediately  upon
                  learning  that any samples  shipped by SB to COMPANY have been
                  lost or have not been received as scheduled. Furthermore, such
                  procedures  shall include a requirement  that COMPANY shall be
                  responsible for reporting  directly to the relevant AGENCY any
                  known  thefts or  significant  losses of  samples,  as such is
                  required by AGENCY  policy or  regulation,  and COMPANY  shall
                  promptly  provide SB with a complete  copy of any such report.
                  In  the  event  that  COMPANY  or  any  of  its   professional
                  representatives fails to comply or causes SB to fail to comply
                  with  any  of  the  requirements  of  the  Prescription   Drug
                  Marketing Act of 1987 (as such may be  subsequently  modified)
                  and a  civil  penalty  is  assessed  against  SB or any of its
                  AFFILIATES or employees,  then COMPANY shall hold harmless and
                  indemnify SB, its  AFFILIATES and their  officers,  directors,
                  shareholders,  employees,  successors  and  assigns  from  and
                  against  any such  civil  penalty  or other  damages or losses
                  related thereto, including attorneys' fees.

         3.3.4    Upon  reasonable  advance  notice  to  COMPANY,  SB  shall  be
                  entitled,  at SB's expense, to conduct an inspection and audit
                  of COMPANY's  sample  allocation at any of COMPANY's  owned or
                  controlled  facilities  where samples of  DENAVIR(R)  received
                  from SB under this  AGREEMENT are stored.  The purpose of such
                  inspection and audit shall be solely to ensure compliance with
                  the applicable  provisions of the Prescription  Drug Marketing
                  Act of 1987 (as such

                  may be subsequently  modified) and with the provisions of this
                  AGREEMENT,  as well  as to copy  records  relating  to  sample

                  designated  distribution  center,  any  samples of  DENAVIR(R)
                  received  by COMPANY  from SB under this  AGREEMENT  which are
                  still in its or its sales representatives possession.

         3.3.6    The parties  understand and acknowledge  that COMPANY does not
                  currently  have the  procedures  in place  to  receive,  store
                  and/or distribute  samples to TARGET PRESCRIBERS in accordance
                  with the terms of this Agreement.  Therefore,  until such time
                  as COMPANY is able to receive, store and/or distribute samples
                  to TARGET  PRESCRIBERS  in  accordance  with the terms of this
                  Agreement,  COMPANY shall not be required to do so;  provided,
                  however,  that COMPANY  agrees to use good faith efforts to be
                  able to  receive,  store  and  distribute  samples  to  TARGET
                  PRESCRIBERS  in  accordance  with the terms of this  Agreement

                  be paid within sixty (60) days after the end of the quarter.

         4.3      In the event that the first PROMOTION PERIOD does not commence

                  reduced  term of the  PROMOTION  PERIOD.  In  particular,  the
                  DENAVIR(R)  PRESCRIPTION  BASELINE and GROSS PRESCRIPTIONS for
                  the  abbreviated   PROMOTION  PERIOD  shall  be  appropriately
                  reduced based on the actual number of months that have elapsed

                  compensation  for an additional one month period following the
                  effective date of such termination. Such compensation shall be
                  calculated in accordance with this Section 4.

         whatsoever,  or to create or impose any  contractual or other liability
         on the other party without said party's authorized written approval.

10.      RETURN/RECALL

10.1     Any DENAVIR(R) or DENAVIR(R) related items returned to COMPANY shall be

         other documented direct cost to be paid by SB.

         any other cause beyond the control of the party; and provided that such
         failure or omission  resulting from one of the above causes is cured as
         soon  as  practicable  after  the  occurrence  of  one or  more  of the
         above-mentioned.

12.      SECRECY AND NON-USE

12.1     All confidential information which is received by either party from the
         other party during the TERM OF THE  AGREEMENT  shall be  maintained  in

         same  degree of care used by such  employees  when  dealing  with their
         employer's  confidential  information,   but  in  no  event  less  than
         reasonable care.  Further,  such information  shall not be disclosed to
         any other person, firm, or AGENCY, governmental or private, or used for
         purposes other than set forth herein, without the prior written consent
         of the disclosing party except to the extent that the information:

                  is documented in its tangible records, or

         12.1.2   is properly in the public domain, or

         12.1.3   is  subsequently  disclosed to the receiving  party by a THIRD
                  PARTY who may lawfully do so, or

         12.1.4   is independently developed by the receiving party, or

12.2     Upon termination or expiration of this AGREEMENT,  and upon the request
         of the  disclosing  party,  the  receiving  party shall return all such
         information  and copies  thereof  in its  possession,  except  that the
         receiving  party  may keep one copy of such  information  in its  legal
         department  confidential  files  solely  for  archival  purposes.  Such
         archival copy will be deemed to be the confidential  information of the
         disclosing  party,  and will not be copied or distributed in any manner
         without the express prior written  permission of the disclosing  party,
         except as otherwise provided in Paragraph 12.1.

13.      TERM AND TERMINATION

13.1     The TERM OF THE  AGREEMENT  is as defined in  Paragraph  1.14,  and the
         AGREEMENT  shall expire upon the  expiration of the period  outlined in
         Paragraph 1.14 unless the parties mutually agree, in writing, to extend
         the TERM OF THE  AGREEMENT  in  accordance  with  Paragraph  13.6.  The
         AGREEMENT may be terminated  earlier than the expiration of the TERM OF
         THE AGREEMENT as provided in this Article 13.

13.2     Notwithstanding Paragraph 13.3 below, SB may terminate the AGREEMENT at
         any  time,  upon  five  (5)  days  written  notice,  if  SB  reasonably
         determines  that COMPANY has  breached  any warranty or  representation
         made by COMPANY under this AGREEMENT,  including,  without  limitation,
         those outlined in Paragraphs  3.1.1,  3.1.5.2,  3.1.6,  3.1.7, or if SB
         reasonably determines that COMPANY is otherwise acting illegally in the
         manner in which it is PERSONAL  SELLING or PROMOTING  DENAVIR(R) in the
         TERRITORY,  or if SB reasonably  determines that COMPANY is interfering
         with SB's rights under Paragraph 3.1.10.

13.3     If either  party  materially  fails or  neglects  to  perform  material
         covenants or  provisions  of this  AGREEMENT and if such default is not
         corrected  within thirty (30) days after receiving  written notice from
         the other party with  respect to such  default,  such other party shall
         have the right to terminate  this AGREEMENT by giving written notice to
         the party in default  provided the notice of termination is given prior
         to correction of the default.

13.4     SB may terminate  the AGREEMENT at any time by giving  COMPANY at least
         thirty  (30) days  written  notice  thereof for  business or  strategic
         reasons, including, without limitation, in the event:

                  (a)  DENAVIR(R)  is approved by the  appropriate  AGENCIES for
         sale in the TERRITORY as an over-the-counter product; or
                  (b) SB determines,  in its sole  discretion,  to embark upon a
         direct to consumer  advertising effort for DENAVIR(R) in the TERRITORY;
         or
                  (c) SB determines, in its sole discretion, to directly conduct
         PERSONAL  SALES and PROMOTE  DENAVIR(R)  to TARGET  PRESCRIBERS  in the
         TERRITORY.

13.5     COMPANY may  terminate  the AGREEMENT at any time by giving SB at least
         thirty  (30) days  written  notice  thereof for  business or  strategic
         reasons.

13.6     In the event that the AGREEMENT  expires in accordance  with  Paragraph
         13.1,  or is  terminated  by either SB or  COMPANY in  accordance  with
         Paragraphs 13.4 or 13.5, respectively,  SB and COMPANY agree to discuss
         in good  faith for no more  than  thirty  (30) days (or such  longer or
         shorter period as may be mutually agreed upon by the parties) the terms
         and  conditions of an  arrangement  pursuant to which the parties would
         continue to work together to promote  and/or market  products to TARGET
         PRESCRIBERS including, without limitation, DENAVIR(R) and PERIOSTAT(R);
         provided,  however,  that it is  expressly  understood  and agreed that
         neither  party  shall be under  any  obligation  to enter  into such an
         arrangement.  The parties acknowledge and understand that the terms and
         conditions of such an arrangement may be  substantially  different than
         the terms of this  AGREEMENT  as a result of changes in  circumstances,
         including,  without  limitation,  the  approval  of  DENAVIR(R)  by the
         appropriate  AGENCIES  for  marketing  and  sale  in the  TERRITORY  as
         over-the-counter product.

13.7     Either party may terminate  this  AGREEMENT if, at any time,  the other
         party  shall  file in any court or agency  pursuant  to any  statute or
         regulation  of any  state or  country,  a  petition  in  bankruptcy  or
         insolvency  or for  reorganization  or for an  arrangement  or for  the
         appointment of a receiver or trustee of the party or of its assets,  or
         if the other  party  proposes a written  agreement  of  composition  or
         extension  of its debts,  or if the other party shall be served with an
         involuntary  petition  against it, filed in any insolvency  proceeding,
         and such petition shall not be dismissed with sixty (60) days after the
         filing  thereof,  or if the other party shall  propose or be a party to
         any  dissolution  or  liquidation,  or if the other party shall make an
         assignment for the benefit of creditors.

13.8     SB may terminate  this AGREEMENT upon thirty (30) day written notice in
         the event  either  party is the subject of a "Change of  Control."  For
         purposes of this  Paragraph,  a "Change of Control"  shall mean (i) the
         sale or conveyance of all or substantially all of the party's property,
         business or assets, whether tangible or intangible,  or (ii) the merger
         or consolidation  with any other corporation  (other than an AFFILIATE)
         or (iii)  the  completion  of any  transaction  or  series  of  related
         transactions in which more than fifty percent (50%) of the voting power
         or equity interests of the party are disposed of.

13.9     During any period  preceding the effective  date of  termination,  each
         party shall  continue to  diligently  fulfill all  obligations  of this
         AGREEMENT,  which  shall  continue  to  apply  during  such  period  in
         accordance with the provisions of this AGREEMENT.

13.10    The termination of this AGREEMENT shall not affect SB's  obligations to
         pay any amount owing to COMPANY  which  accrued  prior to the effective
         date of termination.  Termination or expiration of this AGREEMENT shall
         terminate all  obligations  and rights between the parties arising from
         this AGREEMENT except those described in Article 12 and Paragraphs 4.5,
         13.6,  13.10,  14.3,  15.2,  15.3,  15.4 and 15.5, as well as any other
         provision  which, by its terms, is stated to survive the termination or
         expiration of this

                                                                  EXECUTION COPY



         AGREEMENT.  In addition,  any other provision required to interpret and
         enforce the parties' rights and  obligations  under this AGREEMENT also
         shall  survive  to the extent  required  for the full  observation  and
         performance of this AGREEMENT by the parties hereto.

14.      RECORDKEEPING PROVISIONS

14.1     As a courtesy,  COMPANY  agrees to use good faith  efforts to submit to
         SB, within twenty (20) days of the end of each month during the TERM OF
         THIS  AGREEMENT,  an accounting  of all PERSONAL  SALES made by COMPANY
         sales  representatives  for  DENAVIR(R)  to TARGET  PRESCRIBERS  in the
         TERRITORY  made  during  such  month,  and  any  other  information  in
         COMPANY's  possession which SB reasonably deems necessary regarding all
         such PERSONAL SALES;  provided,  however,  that is expressly understood
         and agreed that  failure of COMPANY to provide such reports to SB shall
         not be deemed a material breach of this Agreement (so long COMPANY uses
         good faith efforts to provide such reports). The PERSONAL SALES reports
         shall be in a form mutually  acceptable  to both parties.  In the event
         SB, in good  faith,  believes  that  such  information  is  inaccurate,
         COMPANY  and SB shall  promptly  meet to  attempt  to reach a  mutually
         acceptable  conclusion on such matter.  In the event the parties cannot
         reach  such  mutually  acceptable  conclusion,  SB may pursue its audit
         option under Paragraph 14.2.

14.2     SB,  at  its  expense,   may  request  and  COMPANY   shall  permit  an
         independent,  certified public  accountant,  except one to whom COMPANY
         has a reasonable  objection,  to have access during  ordinary  business
         hours to COMPANY's  records  necessary to determine the  correctness of
         any  data  supplied  to  SB  by  COMPANY  under  Paragraph  14.1.  Such
         examination  shall  not take  place  more  than  once  for  each  given
         PROMOTION PERIOD.

14.3     SB shall  keep  accurate  records  in  sufficient  detail to enable the
         amount due to COMPANY under Article 4 to be determined. In this regard,
         SB shall submit to COMPANY, within sixty (60) days after the end of the
         first  PROMOTION  PERIOD and after each quarter during each  subsequent
         PROMOTION PERIOD, if any, a statement of all GROSS PRESCRIPTIONS during
         such period and the calculation of INCREMENTAL RX for such period. Upon
         COMPANY's request,  and at its expense, SB shall permit an independent,
         certified  public  accountant,  except one to whom SB has a  reasonable
         objection,  to have  access  during  ordinary  business  hours  to SB's
         records,  but only to the extent necessary to determine the correctness
         of any report or payment.  Such  examination  shall not take place more
         than once for any given PROMOTION  PERIOD.  These requests with respect
         to any PROMOTION  PERIOD shall  terminate  twelve (12) months after the
         end of such  PERIOD.  No  information  other than a statement as to the
         correctness  of any report or payment  shall be  supplied to COMPANY by
         such  accountant.  In the event of a determination  by the independent,
         certified public accountant that there has been an inaccurate report or
         payment made hereunder,  an appropriate adjustment shall be made to the
         next  payment  due to  COMPANY.  In the  event  the  audit  reveals  an
         underpayment  by SB  of  greater  than  five  percent  (5%),  SB  shall
         reimburse COMPANY for the reasonable costs and expenses associated with
         the audit.

15.      WARRANTIES, REPRESENTATIONS, INDEMNIFICATIONS & INSURANCE

15.1     Each party  warrants and  represents  to the other that it has the full
         right and  authority to enter into this  AGREEMENT,  and that it is not
         aware of any  impediment  that would inhibit its ability to perform any
         of its obligations under this AGREEMENT.

15.2     SB shall defend,  indemnify and hold  harmless  COMPANY,  its officers,
         directors,  shareholders,  employees,  successors  and assigns from and
         against all claims,  complaints, or lawsuits for damages that arise (i)
         as a result of the  activities of any employee or agent of SB or anyone
         acting  on  behalf  of SB,  such  as any of its  employees,  agents  or
         representatives, including, but not limited to, negligence, malfeasance
         or willful  misconduct,  (ii) as a result of personal injury,  death or
         tangible  personal  property damage that is alleged to have been caused
         by or  attributed  to any  DENAVIR(R)  which  is  dispensed,  utilized,
         ingested, and/or administered in the TERRITORY, provided:

            (a) SB shall not be obligated under this Paragraph if it is shown by
        evidence  acceptable  in a court  of law  having  jurisdiction  over the
        subject  matter and  meeting  the  appropriate  degree of proof for such
        action,  that (i) the injury was the  result of the  performance  by any
        employee or agent of COMPANY or anyone acting on behalf of COMPANY, such
        as any of its employees,  agents or representatives,  including, but not
        limited to, negligence,  malfeasance or willful  misconduct,  unless the
        primary legal theory of the complaint is related to a product defect due
        to a failure  to inform  and  COMPANY  has  followed  the  training  and
        instructions provided by SB under this AGREEMENT, or (ii) the injury was
        the result of the  failure to adhere to the terms of this  AGREEMENT  by
        any employee or agent of COMPANY or anyone  acting on behalf of COMPANY,
        such as any of its employees, agents or representatives,  including, but
        not limited to, negligence,  malfeasance or willful misconduct, or (iii)
        the injury was the result of a breach of any warranty or representation,
        whether express or implied, made by COMPANY under this AGREEMENT;
            (b) SB shall have no obligation  under this Paragraph unless COMPANY
        (i) gives SB prompt  written  notice  of any claim or  lawsuit  or other
        action for which it seeks to be indemnified  under this AGREEMENT,  (ii)
        SB is granted full  authority  and control  over the defense,  including
        settlement,  against  such claim or lawsuit or other  action,  and (iii)
        COMPANY cooperates fully with SB and its agents in defense of the claims
        or lawsuit or other action; and
            (c) COMPANY  shall have the right to  participate  in the defense of
        any such claim, complaint,  suit, proceeding or cause of action referred
        to in this  Paragraph  utilizing  attorneys  of its  choice,  at its own

        shown by evidence  acceptable in a court of law having jurisdiction over
        the subject matter and meeting the appropriate  degree of proof for such
        action,  that  the  injury  was the  result  of the  performance  by any

        such claim,  complaint,  suit, proceeding or cause of action referred to

        handle any such claim,  complaint,  suit, proceeding or cause of action,
        including any  settlement  or other  disposition  thereof,  for which SB
        seeks indemnification under this Paragraph.

         complaint,  suit,  proceeding  or cause of action  brought  against one
         party containing allegations of liability based on activities for which
         such party was responsible, such party shall control and bear financial

                         DISTRIBUTION SERVICES AGREEMENT

     This  agreement  is  made  as  of  August  15,  1998,   between  CollaGenex
Pharmaceuticals,  Inc., a Delaware corporation  ("Client"),  and CORD Logistics,
Inc., an Ohio corporation ("CORD").

                             Background Information

     A. Client is,  among  other  things,  in the  business  of  developing  and
marketing pharmaceutical products in the United States, the District of Columbia
and Puerto Rico (the "Territory").

     B. CORD  is,  among  other  things,   in   the  business  of   distributing
pharmaceutical  products to  wholesalers,  specialty  distributors,  physicians,
clinics,  hospitals,  retail pharmacies,  and other health care providers in the
Territory,  and of providing Information Systems and other services that support
its clients' use of its distribution capabilities.

     C. Client  desires to engage CORD as its exclusive  distribution  agent for
Periostat(R)  (the  "Product")  in the  Territory,  following  FDA  approval  of
Periostat(R), and to perform certain other services described in this agreement,
all upon the terms and conditions set forth in this agreement.

                             Statement of Agreement

     Customer and CORD (the  "Parties")  hereby  acknowledge the accuracy of the
above Background Information and agree as follows:

     Section 1.  Appointment.  Upon the terms and  conditions  described in this
agreement,  Customer hereby appoints CORD as its exclusive distribution agent in
the Territory for distribution of the Product and Product samples (collectively,
the "Product") to Clients's direct customers ("Customers").

     CORD's  services to Client shall be as described below and in the Operating
Guidelines (defined in Section 6) to this agreement (the "Services"). Changes to
such Operating  Guidelines  may only be made with the prior written  approval of
CORD  and  Client.  Such  requirements  in  the  Operating   Guidelines  may  be
supplemented or amended from time to time by Client with 30 days prior notice to
and approval by CORD, which approval shall not be unreasonably withheld. If CORD
notifies Client in good faith that any such supplement or amendment will require
a  material   modification  to  the  CORD  Facility  or  CORD's   procedures  or
requirements  which are  unique and  specific  to the  Product  or the  Services
resulting in a material increase to CORD's anticipated costs and expenses,  then
Client and CORD shall  consult  regarding  such  reasonable  costs and  expenses
(hereinafter,  simply "unique costs") and the parties shall negotiate the extent
to which Client shall pay such unique costs resulting from that modification.

     Section 2. Product Supply,  Warehousing and Storage.  Client shall ship the
Product to CORD at CORD's  distribution  facility currently located at 1135 Heil
Quaker Boulevard,  Suite 100, La Vergne, TN 37086 or to such other  distribution
facility  in the  Territory  as may  be  designated  by  CORD  (individually  or
collectively,  the "CORD Facility"),  in sufficient  quantities to meet Client's
anticipated  Customer  orders.  CORD shall visually inspect each shipment of the

<PAGE>

Product for external  damage or loss in transit and notify Client of such damage
or loss within ten days following discovery of such damage or loss by CORD.

     Client shall provide CORD with  projections  of its  anticipated  quarterly
shipments  of Product to CORD no later  than 30 days prior to the  beginning  of
each  quarter.  CORD shall store the Product in the CORD  Facility in accordance
with the requirements outlined in the Operating Guidelines. Client shall pay all
costs and expenses of  delivering  the Product to the CORD  Facility.  CORD will
never take title to the  Product,  even when such Product is located at the CORD
Facility.

     Section 3.  Standard  Product  Distribution.  All Customer  orders shall be
processed by CORD as described in the Operating  Guidelines.

     Customer  orders will be delivered by a courier  mutually  chosen by Client
and CORD.  CORD will invoice Client for such handling  services and freight cost
on a monthly  basis.  CORD will use  reasonable  efforts to manage any claims by
Client against the courier,  provided,  however,  that CORD shall not be be held
responsible for all lost or damaged shipments.

     In  addition,  Client  shall  reimburse  CORD for all  costs  and  handling
expenses of  packaging  material  used for shipping the Product and all business
forms unique to Client (e.g., packing slips, invoices, etc.).

     The Product shall be shipped on a first expiration  date-first out basis or
as otherwise  directed by Client. In addition,  CORD shall establish (and Client
shall approve) procedures for the processing and shipment of emergency orders on
weekends and holidays,  provided that Client shall  separately pay all increased
costs resulting from such orders.

     Section 4. Product Prices. Within thirty days prior to launch, Client shall
deliver to CORD a Product price list for Customers who purchase the Product (the
"Customer  Price List").  Client shall notify CORD of any change in the Customer
Price List not less than 10  business  days prior to the  effective  date of any
such change.  The Parties hereby  acknowledge that Client,  and not CORD, is the
seller of the Product to Customers.

     Section 5. Financial Support Services.

     (a) CORD shall perform the,  billing,  contract pricing  maintenance,  cash
application,   collections,   chargeback  processing,   and  reporting  services
described in the Operating Guidelines (the "Financial Support Service).

     (b) CORD shall have no  obligation  to pay for the Product or to  reimburse
Client for any losses incurred in connection with the failure of any Customer to
pay Client any amount due.

     (c)  Customers  shall be  directed  to make  payments  for the  Products in
accordance with the Operating Guidelines.

     Section  6.  Operating  Guidelines.  CORD and  Client  have  developed  the
"operating  guidelines"  relating to the product and the services,  which define
and  document  the  responsibilities  of  CORD  and  Client  in  support  of the
relationship  described in this  agreement  (the  "Operating  Guidelines").  The

Operating  Guidelines.  All Operating  Guidelines  shall be  implemented in good
faith and in a commercially reasonable manner, subject to the qualifications set

     If Client is required  to recall,  or, on its own  initiative,  recalls any
Product,  CORD  will  assist  Client  with that  recall  in all ways  reasonably
requested by Client ("Product Recall Services");  provided that Client shall pay
to CORD an amount equal to all  reasonable  costs incurred by CORD in connection

         storage    of    product    and    distribution     services.     These
         Storage/Distribution  Fees  shall be based  upon the  number of pallets
         stored  per month at the  Facility,  and the  number of  Invoice  Lines
         (defined below) of Product shipped from the CORD Facility or the number
         of Invoice Lines of Product returns received at the CORD Facility.  The
         Storage/Distribution Fees shall be calculated as described in  (the Fee
         Schedule) and the following provisions of this section. For purposes of
         this  agreement,  the term  "Invoice  Line"  shall  mean:  (i) for each

         (shelf-keeping  unit) specified in the packing slip, shipping manifest,
         or other similar  document  dispatched  with such shipment and (ii) for
         each Customer return processed, including recall returns, each distinct
         SKU included as part of that return. For each calendar month, the total
         number of Invoice  Lines to be calculated  for purposes of  determining
         the  amount of the  Storage/Distribution  Fees  payable  for that month
         shall be determined by aggregating  the Invoice Lines  contained in all
         shipments completed and returns processed during such month.

      c) Information  System  Access and Use Fees.  This  component  of the Fees
         shall cover Client's access and use of CORD's or an affiliate of CORD's

         Services Fees") shall be in the amount specified in Exhibit A.

      e) Customer  Service Fees.  This  component of the Fees shall be a monthly
         fee as compensation for the Customer Services performed pursuant to the
         Operating Guidelines,  which fees (the "Customer Service Fee") shall be
         in the amount specified in Exhibit A.

      f) Chargeback/Contract  System  Access  and Use Fee.  This Fee shall be as

         Customers,  which fees are included in the  Information  System Fees in
         Exhibit A.

for the prior month. The Fees or other amounts owed to CORD by Client under this
agreement shall be payable within 30 days of the date of CORD's invoice for such

the  maximum  rate  permitted  by law if such rate is less than 1.5% per  month)

     If CORD  can  reasonably  demonstrate  that the  costs  for  providing  the
Services have materially increased,  or are likely to materially increase in the
coming year due to the  adoption of any  applicable  law or  regulation,  or any
material  change  in the  interpretation  or  administration  thereof  (a  "Cost
Adjustment"),  then CORD may propose an increase to the applicable  component of
the Fees as of any anniversary of the Commencement Date by an amount designed to
eliminate any Cost Adjustment; provided that the costs used for determining such
increases shall be reasonably  determined  under Generally  Accepted  Accounting
Principles and cost allocation methods applied on a consistent basis. CORD shall
notify  Client of any such proposed  Cost  Adjustment  not less than 120 days in
advance. If CORD and Client cannot agree on such proposed Cost Adjustment,  then
Client may terminate  this agreement on 90 days notice,  and no Cost  Adjustment
will apply during such remaining 90 days until termination.

     Section 10. Term and  Termination.  (a) The initial term of this  agreement
(the  "Initial  Term") shall begin on the date that  inventory of the Product is

until the third anniversary of the Commencement Date, unless or until terminated
sooner pursuant to the other provisions of this section. After the Initial Term,
this agreement  shall renew  automatically  for successive  renewal terms of one
year each unless  notice of  termination  is given by any Party at least 90 days

of this agreement" shall include the Initial Term and any such renewal terms.

breach by the other Party of a material  provision  of this  agreement  and that
Party's  failure to cure such breach within  30-days  following  written  notice
thereof  from the  non-breaching  Party  or, in the event  such  failure  is not
capable of being cured within such 30-day period,  the breaching Party's failure
to continue to diligently prosecute such cure thereafter;  provided,  that, with
respect to any failure to make any payment when due under this  agreement,  such
period in which to cure shall be reduced to 10 days.

     (c)  Either  Party  shall  have  the  right  to  terminate  this  agreement
immediately  upon notice to the other Party  following the  commencement  of any
bankruptcy or insolvency  proceeding  (whether  voluntary or  involuntary)  with
respect  to such other  Party or its  assets,  the  general  assignment  for the
benefit of  creditors  by such other Party,  or the  appointment  of a receiver,
trustee or liquidator by or for such other Party.

     (d) Sections 13 and 15 through 18, inclusive, and the first paragraph under
"Warehousing"  in the Operating  Guidelines in Exhibit D of this agreement shall

the other and its parent and affiliates, and each of their directors,  officers,

made by that Party in this  agreement.  Client  further  agrees to indemnify and
hold harmless CORD and its parent and  affiliates  and each of their  directors,
officers,  employees,  agents and  representatives  from and against all claims,
liability,  losses,  damages,  costs, and expenses (including without limitation
reasonable  attorney's  fees) arising  directly or  indirectly  out of injury or

the property  damage  insurance  policy(ies).  Prior to the  Commencement  Date,
Client shall deliver to CORD  certificates  evidencing  such  insurance.  Client

United States mail,  first-class postage prepaid, and addressed to that Party at

business day after delivered to Federal Express,  Airborne, or any other similar
express delivery service for delivery to that Party at that address; or (c) when

notices under this agreement by giving the other Parties notice of such change.

     Section  21.  Remedies.  Each Party  acknowledges  that in the event of any
violation  by that Party of any of the  provisions  of Section 15 and 16 of this
agreement, the other Party would suffer irreparable harm and its remedies at law
would be  inadequate.  Accordingly,  in the event of any  violation or attempted
violation  of any such  provisions  by either  Party,  the other  Party shall be
entitled to a temporary restraining order,  temporary and permanent injunctions,
specific  performance,  and other  equitable  relief,  without  any  showing  of
irreparable  harm or damage or the posting of any bond.  The rights and remedies
of each Party under this  agreement  shall be cumulative  and in addition to any
other  rights or  remedies  available  to such  Party,  whether  under any other
agreement, at law, or in equity.

     23  Severability.  The intention of the Parties is to comply fully with all
laws and public  policies,  and this agreement  shall be construed  consistently
with all laws and public policies to the extent  possible.  If and to the extent
that any court of competent  jurisdiction  determines  that it is  impossible to
construe any  provision of this  agreement  consistently  with any law or public
policy and consequently  holds that provision to be invalid,  such holding shall
in no way affect the validity of the other  provisions of this agreement,  which
shall remain in full force and effect.

     Section 24.  Non-waiver.  No failure by either  Party to insist upon strict
compliance with any term of this agreement,  to exercise any option,  to enforce
any right,  or to seek any remedy  upon any  default  of the other  Party  shall
affect, or constitute a waiver of, the first Party's right to insist upon strict
compliance,  to exercise  that option,  to enforce  that right,  or to seek that
remedy with respect to that default or any prior, contemporaneous, or subsequent
default.  No custom or practice of the Parties at variance with any provision of
this  agreement  shall affect,  or constitute a waiver of, that Party's right to
demand strict compliance with all provisions of this agreement.

     Section 25. Force Majeure. If the performance of any part of this agreement
by  either  Party  shall be  affected  for any  length  of time by fire or other
casualty,  government restrictions,  war, riots, strikes or labor disputes, lock
out,  transportation  delays,  acts of God, or any other causes which are beyond
the control of the  Parties,  such Party shall not be  responsible  for delay or
failure of  performance  of this  agreement  for such length of time,  provided,
however,  that the obligation of one Party to pay amounts due to any other Party
shall not be subject to the  provisions of this section.

attached  hereto and the other  documents  referred to herein,  all of which are
hereby  incorporated  herein by reference) contains the entire agreement between
the  Parties  and   supersedes   all  prior  or   contemporaneous   discussions,
negotiations, representations, warranties, or agreements relating to the subject
matter of this  agreement.  No  changes  to this  agreement  shall be made or be
binding on either Party unless made in writing and signed by both Parties.

Party  shall  have the right to assign  this  agreement  or any of such  Party's
rights or obligations  under this agreement without the prior written consent of
the other Party,  which consent shall not be unreasonably  withheld.  Subject to

agreement  or  the  Distribution   Agreement  to  the  contrary,   each  party's
obligations  under this agreement  (exclusive of payment  obligations)  shall be
excused  if and to the  extent  that  any  delay  or  failure  to  perform  such
obligations is due to fire or other  casualty,  material  shortages,  strikes or
labor  disputes,  acts of God, or other causes beyond the reasonable  control of
that party.

            10. Successors. Licensee shall not assign or otherwise transfer this

construe any  provision of this  agreement  consistently  with any law or public
policy and consequently  holds that provision to be invalid,  such holding shall
in no way affect the validity of the other  provisions of this agreement,  which
shall remain in full force and effect.

CollaGenex  Pharmaceuticals Inc. ("CollaGenex").  These Operating Guidelines are
in addition to CORD Information Systems Operating  Instructions,  as well as the
CORD  Standard  Operating  Procedures  ("SOPs").  Copies of these  documents are
maintained by both parties and will be reviewed, and updated if necessary,  from
time to time as mutually agreed, but not less than once per calendar year.

WAREHOUSING
- -----------

CORD will  maintain  its  warehouse  facility in  accordance  with all state and
federal licensing requirements and will ensure full compliance with Prescription
Drug  Marketing Act and FDA guidelines  and  regulations.  CORD will ensure full
compliance with all cGMP, SOP and QA procedures.  Documented  training  programs
will be maintained by CORD.

CORD will comply with storage,  handling and shipping  conditions  designated by
CollaGenex  for the  Products.  Products  will be stored in an area with secured
access,  accessible only to authorized CORD personnel as agreed to by CollaGenex
and CORD.

Inventory  will be received  into and tracked on an automated  inventory  system
capable of full lot tracking on a shipment by shipment basis.  Inventory must be
recorded  and  controlled  by SKU,  by lot number and by  expiration  date.  Any
quarantined  Product must be physically  segregated and  appropriately  labeled.
Quarantined Product can only be released from quarantine status in the automated
inventory system by an authorized CollaGenex or, if designated by CollaGenex,  a
CORD QA  employee  and  physically  released  by an  authorized  CORD  employee.
Inventory will be routinely verified by CORD through weekly cycle counts. Should
deviations occur,  CollaGenex and CORD will jointly determine corrective actions
required.  CollaGenex  and their  auditors  will have  access  for  pre-arranged
physical  inventory  observations.  CORD will notify  CollaGenex  of all expired
Product  or  Product  which has  reached  "short  dated"  status,  specified  by
CollaGenex to be six months prior to expiration  date.  Disposition of returned,
rejected or expired Product must be handled according to CollaGenex's direction.

DISTRIBUTION
- ------------

CORD and  CollaGenex  will agree upon a common  carrier  that  provides the most
favorable rates and pick up schedule.  CORD will procure and bill CollaGenex for
all shipping materials in accordance with this Agreement.  CORD's proposal.  All
Product will be shipped  utilizing  packaging  and shipping  carton(s) as deemed
appropriate by CORD.  Unless instructed  otherwise by CollaGenex,  shipping will
occur based on the shipping procedures provided by CollaGenex.

CORD will comply with First to Expire,  First Out (FEFO)  inventory  allocation.
Any deviations from FEFO must have prior approval by CollaGenex in writing.

<PAGE>

CORD will perform quality  verification by an individual other than the employee
whom picked the order, on all CollaGenex shipments. All orders will be confirmed
on the same business day in which shipment occurs.

CORD will establish an account for CollaGenex with the carrier  selected by CORD
and approved by CollaGenex.  If UPS is the selected  carrier,  shipping  charges
will be billed  directly to CORD's  account and passed through to CollaGenex per
the  Distribution  Agreement.   All  freight  and  insurance  will  be  paid  by
CollaGenex. Title will pass to the customer at the point of delivery to a common
carrier. CORD will perform proof of delivery or freight claim services on behalf
of the customer for CollaGenex. In the event of legitimate customer claims, CORD
will issue a credit to the  customer  for the invoice  amount.  CollaGenex  will
approve all such credits.

CUSTOMER CREDIT
- ---------------

CollaGenex  will determine the customers to whom it will sell on a direct basis.
Customer class  definitions  will be  established  and customers will be grouped
according to their functional criteria. Wholesalers will be required to sign the
CollaGenex  Distributor  Agreement  form  which will  automatically  renew on an
annual basis until terminated by either Party.

CollaGenex will assign credit limits to customers.  The CORD system will monitor
orders and outstanding  accounts  receivable  against such credit limit and hold
orders as  needed.  Additionally,  CollaGenex  may  elect to place a  customer's
account on credit hold so that all orders are reviewed  prior to  shipment.  All
orders held for credit  limits or for credit hold will be reviewed  and approved
by CollaGenex prior to shipment.

CORD will be responsible  for inputting and for maintaining  customer  profiles.
The  initial  set up will be verified  to  information  provided by  CollaGenex.
Subsequent  customers will be added after a customer profile automation form has
been completed by CollaGenex.

CUSTOMER SERVICE
- ----------------

CORD will staff the CollaGenex  Customer Service line from 7:00 a.m. - 6:00 p.m.
central  standard  time. No more than two rings will occur before the customer's
call is handled.  As a backup to the customer service  representatives,  a voice
mail  system  will be  maintained  to accept  telephone  orders  and to  collect
messages from customers.  CORD's dedicated  customer service line for CollaGenex
will  incorporate  programming  to  forward  calls  to a  CollaGenex  designated
clinical service phone number if calls of a clinical nature are received outside
of regular customer service hours.  CORD's Customer Service  representative will
be knowledgeable about CollaGenex and the Product and will conduct themselves in
a courteous and professional manner.

Orders
- ------

Orders will be accepted via EDI, telephone,  fax or mail. All orders received by
2:00  p.m.  central  time and  validated  as  approved  orders  will be  shipped
according  to  CollaGenex's  shipping  procedures.  EDI orders will be collected
throughout the day, accordingly to a pre-determined  scheduled developed by CORD
and  CollaGenex.  EDI Orders  received  after  12:00 p.m.  central  time will be
shipped the following  shipping day,  excepting  holidays and days designated by
CollaGenex as non-shipment dates.

ordering instructions.

CollaGenex  will instruct its customers to place orders based on the  CollaGenex
Distribution Agreement.  However at CollaGenex's discretion,  the policy may not
be enforced at launch.  Post-launch  customer order  frequency will be monitored
via a report  furnished  by  CORD.  Customers  habitually  exceeding  the  order
frequency policy may be required to pay freight costs. CollaGenex will determine
when  this  policy  will be  enforced  and  will  notify  CORD  of the  specific
instructions for enforcement in writing.

CollaGenex reserves the right to limit quantities,  to hold or to refuse orders.
These decisions will be executed by CORD.

CORD will  ensure  order  entry  accuracy  of 98% or higher for all order  lines
processed  during each  calendar  quarter.  Errors  which may occur  within this
tolerance  range are wrong Product NDC input or incorrect  order quantity input.
Should  deviations occur outside the tolerance  range,  CollaGenex and CORD will
jointly determine corrective actions.

Pricing and Terms
- -----------------

CollaGenex  will  publish  terms to  wholesalers  and  warehouse  chains.  Those
standard  terms are 2% - 30 days;  net 31 days.  Contracted  customers  may have
non-standard terms.

List prices for wholesalers and warehouse chains will be published by CollaGenex
and  are  subject  to  change  from  time  to time  at the  sole  discretion  of
CollaGenex.  Contract  prices will be  determined by CollaGenex on a contract by
contract  basis.  CollaGenex  will  notify  CORD  of  such  price  changes  with
sufficient  notice  for  update  of the CORD  system  files.  Advance  notice to
customers may or may not be provided, at CollaGenex's  discretion.  All customer
notifications will be developed by CORD and approved by CollaGenex.

All  system  maintenance  of  pricing  and  terms  will be  performed  by  CORD.
CollaGenex will provide to CORD in writing any changes to prices or terms.  CORD
will be  responsible  for  updating  the CORD  system  within  24 to 48 hours of
receipt of such  notice.  All CORD  employees  are bound by the  confidentiality
provisions of the Agreement  between CORD and CollaGenex and, as such, shall not
disclose  CollaGenex sales data or pricing information outside the specific CORD
employees  who  have a need  to  know  of  this  information  in the  course  of
performing their routine job responsibilities.

CORD will provide the necessary  reports  within time frames to be agreed by the
parties to ensure  CollaGenex  can comply  with the  reporting  requirements  of
Medicaid (OBRA), Veterans HealthCare Act, PHS Covered Entities, and state rebate
programs.  CollaGenex will define reporting requirements against which CORD will
produce the required reports.

INVOICING
- ---------

CORD  Customer  Service  will  ensure all  invoices  are mailed or,  once an EDI
invoicing  system is  implemented,  transmitted via EDI the same business day as
the shipment occurs; or by noon the following business day.

<PAGE>

For any order shipped after the close of business,  the invoice will be prepared
and mailed the following business day.

Once an EDI  invoicing  system  is fully  and  jointly  implemented  by CORD and
CollaGenex, CORD will execute and complete EDI testing for additional CollaGenex
customers within 30 days of the customer's request.

PRIME VENDOR PROGRAM/CHARGEBACKS
- --------------------------------

CollaGenex may enter into prime vendor  arrangements  for contract or government
mandated pricing arrangements.  CollaGenex has the right to accept or refuse the
contractee's request to be named prime vendor. Once EDI chargeback processing is
available,  CollaGenex,  where possible, will encourage the contract customer to
select  a  wholesaler  with  full  EDI   capabilities,   receipt  of  bid  award
notification,   chargeback  submission,  chargeback  reconciliation  and  credit
invoicing to serve as their prime vendor.

CORD,  on  behalf of  CollaGenex,  will run  chargeback  processing  daily  with
reconciliation of chargeback discrepancies within 5 working days. The chargeback
SOP will define the parameters available to CORD to resolve discrepancies.

All  chargebacks  will be  processed  according  to the  chargeback  policy  for
CollaGenex.  All  validated  chargeback  submissions  will be settled via credit
invoice.  CollaGenex  will  not  make  advance  payments  or  authorize  advance
deductions of chargebacks.

Prime vendors will be  instructed  that all returns from  CollaGenex's  contract
customers must be reported as a reverse chargeback. CollaGenex will maintain the
right to audit a prime vendor's records related to chargeback requests.

ACCOUNTS RECEIVABLE
- -------------------

CollaGenex will open and maintain a lockbox.  CORD will receive the notification
of lockbox deposits along with the customer's remittance information.  CORD will
reconcile and apply the cash receipt to the outstanding  accounts  receivable on
the same day as received from the bank or within 24 hours of receipt.  CORD will
have no access to funds in the  lockbox.  To aid the cash  application  process,
CollaGenex  will  authorize  accounts  receivable  payment terms of one day past
published  terms.  This grace period will not be communicated to customers.  For
payments  received with a postmark  beyond the payment  terms grace period,  the
discount  will be  disallowed  and  maintained  as a balance due on the Accounts
Receivable account. CORD will notify the customer of the outstanding balance via
a letter to be developed by CORD

Accounts Receivable will be monitored by CORD with appropriate collection action
taken  as  directed  by  CollaGenex.  The  performance  measurement  for CORD is
confirmation  of the strict  compliance  with the SOP for collection of past due
receivables.
