              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                          SEPTEMBER 30, 1995 AND 1996
                                  (UNAUDITED)

(1) BASIS OF PRESENTATION

    The unaudited condensed consolidated financial statements included
herein have been prepared by the Company, without audit, 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 financial statements
should be read in conjunction with the Company's 1995 audited financial
statements and notes thereto included in the Company's  initial public offering
prospectus dated June 20, 1996.

    In September 1996, the Company formed a wholly owned subsidiary in the
U.K., CollaGenex International Ltd. ("CIL"), to conduct regulatory and
commercialization activities for the Company in Europe.  During the third
quarter of 1996, CIL had no significant activities.

    In the opinion of the Company's management, the accompanying unaudited
condensed financial statements have been prepared on a basis substantially
consistent with the audited financial statements and contain adjustments, all of
which are of a normal recurring nature, necessary to present fairly its
financial position as of September 30,  1996, its results of operations for the
three and nine months ended September 30, 1995 and 1996 and for the period
January 10, 1992 (inception) to September 30, 1996, and its cash flows for the
nine months ended September 30, 1995 and 1996 and for the period January 10,
1992 (inception) to September 30, 1996.  Interim reports are not necessarily
indicative of results anticipated for the full fiscal year.

(2) COMPLETION OF INITIAL PUBLIC OFFERING/CONVERSION OF PREFERRED STOCK

    On June 20, 1996, the Company completed an initial public offering of
2,000,000 shares of its common stock at a price of $10.00 per share.  The
Company's net proceeds from the offering were approximately $18.0 million after
underwriting fees and other expenses.

    On June 19, 1996, more than 60% of the holders of Series A, Series B and
Series C mandatorily redeemable convertible preferred stock approved an
amendment to the respective Series A, B and C agreements to reduce the price per
share upon which the mandatory conversion of the preferred stock shall occur
upon the closing of an initial public offering for the sale of the Company's
common stock from not less than $12.00 to not less than $8.00 per share.   Upon
consummation of the initial public offering, all shares of such convertible
preferred stock outstanding were automatically converted on a one-for-two basis
into 5,199,124 shares of common stock.

(3) COMMITMENT

    In April 1996, the Company entered into a manufacturing agreement for
the manufacture of Periostat. Under the terms of this agreement, the Company is
obligated to make annual minimum purchase commitments with such vendor for three
years following the date of initial product launch, as defined.

(4) LICENSING FEE

    During the third quarter of 1996, the Company executed a licensing
agreement with Boehringer Mannheim Italia ("BMI") pursuant to which BMI will
distribute and manufacture Periostat in Italy.  The agreement provided for BMI
to pay the Company a $400,000 nonrefundable license fee upon signing, additional
fees upon the achievement of future milestones and royalties upon future sales
of Periostat in Italy, San Marino and The Vatican City.  Such fee, net of the
applicable 10% foreign withholding tax, was recorded as an account receivable at
September 30, 1996.  Payment was received in early October.



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


OVERVIEW

        The Company began operations in January 1992 and is engaged in the
development and commercialization of innovative, proprietary medical therapies
for the treatment of periodontal disease and other dental pathologies.  Since
inception, the Company has had no revenues from product sales and has funded
its operations primarily through the issuance of common and preferred stock.
Substantially all of the Company's expenditures to date have been for
pharmaceutical development activities and general and administrative expenses.

    The Company has incurred losses each year since inception and had an        
accumulated deficit of $16.3 million at September 30, 1996.  The Company expects
to continue to incur losses over the next several years from expenditures on
clinical, product development, marketing and administrative activities.

    The Company does not expect to generate any revenues from product sales
in 1996 or 1997.  No assurance can be given, however, that product sales will be
achieved in the future.  Successful future operations will depend on the
Company's ability to develop, obtain regulatory approval for and commercialize
its products.

    RESULTS OF OPERATIONS

    From inception through September 30, 1996, the Company had no revenues
from product sales.  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 clinical trials and, to a lesser
extent, for research grants paid to The State University of New York and other
research institutions.  General and administrative expenses consist primarily of
personnel salaries and benefits, professional and consulting fees, facilities
and general office expenses.  The Company anticipates that selling, general and
administrative expenses will increase during the next several years due to the
expansion of its corporate infrastructure, primarily in sales, marketing and
finance.

    The Company earned $400,000 in licensing fee revenue during the three
and nine month periods ended September 30, 1996, compared to no revenues
during the comparable periods in 1995.  This revenue resulted from the signing
of a licensing agreement with Boehringer Mannheim Italia.  See Note 4 of Notes
to Condensed Consolidated Financial Statements.

    Research and development expenses increased $258,000, or 25%, and
$762,000, or 27%, respectively, during the three and nine month periods ended
September 30, 1996 over the comparable year earlier periods due to higher
contract costs associated with preparing and submitting the New Drug Application
("NDA") for Periostat, including data compilation, statistical analysis and 
validation of production processes.  General and administrative expenses
increased $345,000, or 86%, and $740,000, or 77%, respectively during these
periods due to the hiring of additional staff (which  resulted in a non-cash
compensation charge of approximately $125,000 during the nine months ended
September 30, 1996 from the grant of certain employee stock options) and to
higher consulting and legal fees.

    LIQUIDITY AND CAPITAL RESOURCES

    On June 20, 1996, the Company completed an initial public offering of
2,000,000 shares of common stock at a price of $10.00 per share, which generated
net proceeds to the Company of approximately $18.0 million after underwriting
fees and related expenses.  At September 30, 1996, the Company had cash and cash
equivalents of $18.9 million.  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 $18.9 million at September 30, 1996 reflected an increase of
$13.6 million from December 31, 1995.

    The Company had no debt outstanding (other than accounts payable and
accrued expenses) at September 30, 1996.  The Company has no lines of credit,
and no capital leases were outstanding at September 30, 1996.

    The Company anticipates that its existing cash resources will be sufficient
to fund the Company's





                                       8
<PAGE>   9
operations through at least 1997.  The Company's future capital requirements
and the adequacy of its available funds will depend on many factors, including
the timing of FDA approval, if any, of the Company's NDA for Periostat, such
NDA having been submitted to the FDA in August 1996,  the magnitude of the
sales and marketing organization to be established, 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.




                          PART II.  OTHER INFORMATION



    ITEM 5.  OTHER INFORMATION

        During the third quarter, the Company executed a licensing agreement
with Boehringer Mannheim Italia ("BMI") pursuant to which BMI will distribute
and manufacture Periostat in Italy.  The agreement provided for BMI to pay the
Company a $400,000 nonrefundable license fee upon signing, additional fees upon
the achievement of future milestones and royalties upon future sales of
Periostat in Italy, San Marino and The Vatican City.  Such fee, net of the
applicable 10% foreign withholding tax, was recorded as an account receivable at
September 30, 1996.  Payment was received in early October.

        In August 1996, the Company entered into a research agreement with
Istituto Gentili, an Italian pharmaceutical company, to evaluate the application
of the Company's technology in the field of osteoarthritis.

        In October 1996, the Company and the National Cancer Institute ("NCI")
executed a letter of intent to formalize a collaborative research and
development agreement pursuant to which the NCI agreed to perform pharmacology,
toxicology and Phase I clinical trials using one of the Company's compounds for
the prevention of cancer metastases.

<PAGE>   3
            1.10 "Territory" shall mean the country of Italy, San Marino and the
Vatican City.

      2.    LICENSES AND OTHER RIGHTS.

            2.1 Grant of Licenses. Subject to the limitations described below,
CollaGenex hereby grants to BMI (i) an exclusive right and license to use,
distribute and sell Products in the Territory, (ii) a non-exclusive right and
license to make, manufacture and use Technical Information to make Products,
(iii) an exclusive right and license under Patents applicable to the Territory,
if any, to use, distribute and sell Products in the Territory, and iv) a
non-exclusive right and license under Patents applicable to the Territory, if
any, to make and manufacture Products in the Territory. BMI shall have no right
to sublicense its rights hereunder to any third party, other than Affiliates of
BMI, for any purpose, including, without limitation, third party manufacturing
of Products, without the express written permission of CollaGenex, which will
not be unreasonably withheld.

            2.2 Exclusivity of License; Title. All exclusive licenses granted to
BMI hereunder will be exclusive as to CollaGenex and all others. CollaGenex
shall retain title to, and be the owner of, any and all (i) Patents, (ii)
Technical Information, (iii) BMI Improvements and (iv) CollaGenex Improvements.
BMI agrees to notify CollaGenex of any BMI improvements. To the extent any BMI
Improvements are covered by Patents and should BMI not be permitted by
applicable law to assign such BMI Improvements to CollaGenex, then BMI agrees to
grant to CollaGenex a perpetual, exclusive (except for BMI's use in the
manufacturing and marketing of Products), irrevocable, royalty free license to
such BMI Improvements. In the event BMI decides not to seek patent protection
for a particular BMI Improvement, CollaGenex shall have the right, but not the
obligation, to seek patent protection for such BMI Improvement. BMI agrees to
execute such documents as reasonably required by CollaGenex to document, record
and otherwise perfect its interests in the Technical Information, Patents and
BMI Improvements. CollaGenex agrees to advise BMI of any CollaGenex Improvements
and, to the extent that it is able, CollaGenex agrees to grant BMI a license to
make, manufacture, use, distribute and sell Products in the Territory using
CollaGenex Improvements. If such CollaGenex Improvements are the subject of a
licensing agreement with a third party, then BMI agrees to abide by the terms of
such licensing agreement, except that it is understood that BMI shall not be
obligated to pay any royalty, licensing fee or other amount to such third party.
BMI understands that the rights granted to them BMI to CollaGenex Improvements
may not be as broad as those rights granted under Section 2.1 hereof.

            2.3 Prohibited Transfers. CollaGenex agrees that, without BMI's
prior express written consent, CollaGenex will not assign, sell, convey, lease,
license, transfer, hypothecate, encumber or suffer imposition of any lien on,
grant any right or interest in, or disclose to any third party any Confidential
Information concerning, the Products in the Territory. BMI shall not disclose
any unpublished Technical Information furnished by CollaGenex pursuant to
Section 2.1 hereof to third parties during the term hereof, or at any time
thereafter; provided, however, that disclosure may be made of any such Technical
Information to the extent necessary to market Products to 


                                     - 3 -
<PAGE>   4
purchasers, provided that such purchasers agree to be bound by a similar
non-disclosure agreement. BMI shall not use any Technical Information furnished
by CollaGenex other than in the manufacture and marketing of Products and only
during the term of this Agreement.

            2.4 Manufacturing Rights. During the term hereof, BMI may either (i)
manufacture Products itself or have Products manufactured by Affiliates or Third
Parties (as set forth in Section 2.1) and/or (ii) purchase Products for resale
by BMI in the Territory from contract manufacturers in the United States
licensed and authorized by CollaGenex to perform such contract manufacturing on
terms and conditions agreed upon by BMI and such third party manufacturers. In
the event BMI or any of its Affiliates develops its own manufacturing capability
for Products, each of BMI and such Affiliate agrees to manufacture such Products
in accordance with (A) any specifications set by any applicable regulatory
authorities and (B) any applicable rules and regulations relating to quality
controls.

            2.5 Supply of Other European Licensees. In the event BMI or any of
its Affiliates develops its own manufacturing capability for the Products, BMI
and such Affiliates agree to manufacture and supply Products to any other
licensees of Products in Europe who have not established their own manufacturing
capability of Products. Such agreements to supply Product will be reached on a
case-by-case basis, based on the availability of manufacturing capacity, and, in
the event that sufficient manufacturing capacity does not exist to supply such
licensees, BMI agrees to notify CollaGenex as soon as possible and to facilitate
the establishment of an alternative source of supply. In case BMI supplies
Product to a licensee of CollaGenex, such Products shall be supplied by BMI at a
price which does not exceed BMI's direct costs plus a 50% mark-up. In supplying
Products to such other licensees, BMI and its Affiliates agree to comply with
all applicable laws and regulations relating to the control of exports or the
transfer of pharmaceutical compounds, drugs and/or technologies, including,
without limitation, Products. It is understood that the sale of Products by BMI
or its affiliates to other licensees of CollaGenex does not represent Net Sales.

            2.6 Government Submissions. As soon as reasonably practicable after
delivery by CollaGenex to BMI of all relevant sections of the New Drug
Application (the "NDA") filed with the United States Food and Drug
Administration ("FDA") with respect to the Product, BMI shall prepare and make
all necessary regulatory filings with all applicable regulatory authorities in
the Territory with respect to the Product. CollaGenex shall provide such
relevant sections of the NDA to BMI on a prompt basis. BMI shall use diligent
efforts to obtain the approval of all necessary regulatory authorities in the
Territory with respect to the Product. BMI shall be the owner and party of
record sponsoring all submissions to regulatory authorities in the Territory
with respect to the Product. The labeling will be agreed upon between the
Parties and prepared in accordance with Regulatory requirements in the
Territory. In the event that BMI is unable to obtain the approval of all
necessary regulatory authorities in the Territory with respect to the Product
within two and one-half (2.5) years from the date CollaGenex supplies to BMI all
relevant sections of the NDA, all rights and licenses granted to BMI by
CollaGenex hereunder shall terminate and such termination shall be 


                                     - 4 -
<PAGE>   5
subject to the provisions of Section 8.6 and 8.7 hereof, unless BMI can provide
written evidence that the delays incurred were beyond its control: in such case
the Parties will agree about a new reasonable term for obtaining the approval.

      3.    LICENSING FEES AND ROYALTY PAYMENTS.

            3.1   Royalty Payments.  In consideration of the license granted
under this Agreement, BMI agrees to pay to CollaGenex the following licensing
fees:

                  (i)   $ *** upon the execution of this Agreement;

                  (ii)  $ *** upon the *** anniversary of the delivery by
                        CollaGenex to BMI of all NDA Documentation, unless BMI
                        can provide written evidence that additional studies are
                        required for the submission of a regulatory filing to
                        the Italian authorities, in which case the payment will
                        be made at the time of submission of the filing;

                  (iii) $ *** upon the regulatory approval of the Products in
                        Italy.

In addition, a running royalty will be paid according to the following terms:

                  (a)   *** percent ( *** %) of the applicable Net Sales of
                        Products for the first *** following first Commercial
                        Sale in the Territory;

                  (b)   *** percent ( *** %) of the applicable Net Sales of
                        Products for *** following first Commercial Sale in the
                        Territory;

                  (c)   *** percent ( *** %) thereafter.

If at any time during the term of this Agreement it can be demonstrated by way
of a recognized market audit (e.g. IMS) that an equivalent competitive Product
has captured at least *** % of the total market for such Products, measured by
volume of sales units, then the royalty rate applicable under (a) and (b) above
will be reduced to *** %.

            3.2 Reports and Payments. Payments pursuant to clauses (i-iii) of
Section 3.1 hereof will be paid to CollaGenex within forty five (45) days after
the triggering event. Payments pursuant to clauses (a-c) of Section 3.1 hereof
will be paid to CollaGenex within sixty (60) days after the end of each calendar
quarter during the term hereof with respect to applicable Net Sales paid to BMI
and/or any Affiliate of BMI during such calendar quarter. With each such
quarterly payment, BMI will provide CollaGenex with a written report stating the
respective Net Sales actually paid to BMI

    Securities and Exchange Commission.


                                     - 5 -

and/or any Affiliate of BMI during such prior calendar quarter and the amount of
royalties earned by CollaGenex thereon pursuant to this Section 3.


            3.3 Recording and Inspection. BMI agrees that for a period of three
(3) years after delivery of each report referred to in Section 3.2, it shall
keep at its principal place of business complete records of applicable Net Sales
received by BMI and/or any Affiliate of BMI and other information necessary to
permit BMI to confirm 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 hereunder. For the sole purpose of
verifying BMI's performance of its obligation to make payments hereunder,
CollaGenex, solely through its independent certified public accountant or other
independent third party designee, will have the right to examine BMI's records
reflecting such Net Sales and other information, provided, that such examination
is made within three (3) years after the close of the calendar year in respect
of which BMI's records are being examined, conducted during BMI's normal
business hours, made after thirty (30) days' advance written notice to BMI and
limited to no more than one examination in any calendar year. The results of
such examination shall be made available to both parties. CollaGenex shall bear
the full cost of the performance of any such examination, unless such
examination discloses a variance of more than *** percent ( *** %) from the
amount of the original report or payment calculation. In such case, BMI shall
bear the full cost of the performance of such examination. BMI shall promptly
pay to CollaGenex any variance disclosed in any such examination.

            3.4 Mode of Payment. All payments shall be paid in U.S. dollars.
Payments due on currencies received other than United States Dollars shall be
translated at the rate of exchange at which United States Dollars are listed in
the Wall Street Journal for Italian Lira on the last business day of the
calendar quarter in which such revenues are received by BMI and/or an Affiliate
of BMI.

      4.    PATENT AND TRADEMARK MATTERS.

            4.1 Patents. CollaGenex shall have the sole right, but not the
obligation, to file, prosecute and maintain all Patents that are the property of
CollaGenex. CollaGenex shall have the sole right to determine whether or not,
and where, to file Patents, to abandon the prosecution of any Patents or to
discontinue the maintenance of any Patents. BMI shall execute such documents as
are reasonably necessary to file, prosecute and maintain all Patents.

            4.2 Recordation. If either BMI or CollaGenex so requests in writing,
the parties will promptly file and record with any applicable patent office or
authority, a copy or memorandum of this Agreement and any other agreement
granting BMI rights in the Products and Technical Information.

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

*** Confidential information has been omitted and filed separately with the

<PAGE>   7
            4.3 Patent Enforcement. BMI shall notify CollaGenex of any suspected
infringement of Patents, if any, in the Territory. CollaGenex shall have the
sole right to institute patent infringement actions against third parties based
on any suspected infringement of Patents in the Territory. BMI shall execute all
necessary and proper documents and take such actions as shall be appropriate,
including, without limitation, making available employees of BMI for testimony
and making available any records, papers, information and other materials, to
assist CollaGenex in instituting and prosecuting such infringement actions. Any
award paid by third parties as a result of such an infringement action (whether
by way of settlement or otherwise), shall be retained by CollaGenex. During the
term hereof, BMI shall notify CollaGenex of any prior art or other information
known to BMI which is relevant to the patentability or validity of any of the
Patents or which might cause a court to deem any of the Patents wholly or partly
inoperative or invalid.

            4.4 Trademarks. BMI will use the trademarks of CollaGenex, if such
trademarks are registrable, in advertising and selling the Products in the
Territory and only in accordance with approved method of use of such trademarks.
This Agreement does not give BMI any rights to changing the trademark or trade
names of any Product.

or proceeding is based on any of the representations or warranties contained in
this Agreement being untrue or upon the breach of any of the provisions of this
Agreement; provided that the indemnified party promptly notifies the

<PAGE>   9
party agrees to cooperate with the indemnifying party, at the indemnifying

hold harmless CollaGenex from any and all Damages arising from injury or damage

will utilize its best efforts to obtain liability insurance covering the
manufacture and sale of Products on terms and in amounts as are customary for
the pharmaceutical industry.

            6.3 Limitation on Damages. In no event shall the liability of

fees and royalty payments paid by BMI to CollaGenex pursuant to Section 3.1
hereof.

            6.4 Limitation on Warranties. NOTHING IN THIS AGREEMENT SHALL BE
DEEMED TO BE A REPRESENTATION OR WARRANTY BY COLLAGENEX OF (A) THE VALIDITY OF
ANY OF THE PATENTS OR (B) THE SAFETY OR USEFULNESS FOR ANY PURPOSE OF ANY OF THE
TECHNICAL INFORMATION AT ANY TIME MADE AVAILABLE BY COLLAGENEX OR (C) THAT THE
PRODUCTS PRODUCED IN ACCORDANCE WITH SUCH TECHNICAL INFORMATION WILL BE FREE
FROM CLAIMS OF INFRINGEMENT OF PATENTS OF ANY THIRD PARTY. COLLAGENEX SHALL HAVE
NO LIABILITY WHATSOEVER TO BMI OR ANY AFFILIATE THEREOF FOR OR ON ACCOUNT OF ANY
DAMAGES ASSESSED OR ASSERTED AGAINST, OR ANY OTHER LIABILITY INCURRED BY OR
IMPOSED UPON BMI OR ANY AFFILIATE THEREOF, ARISING OUT OF OR IN CONNECTION WITH
OR RESULTING FROM (1) THE PRODUCTION, USE OR SALE OF ANY PRODUCTS IN THE
TERRITORY, OR THE PRACTICE OF THE PATENTS EXCEPT FOR THE INFRINGEMENT OF
PROPRIETARY RIGHTS, (2) THE USE OF ANY TECHNICAL INFORMATION DISCLOSED BY
COLLAGENEX OR (3) ANY ADVERTISING OR OTHER PROMOTIONAL ACTIVITIES WITH RESPECT
TO ANY OF THE FOREGOING.

      7.    CONFIDENTIALITY.

            7.1 Confidentiality. Except to the extent expressly authorized by
this Agreement or otherwise agreed in writing, the parties agree that, for the
term of this Agreement and for five (5) years thereafter, the recipient shall
keep completely confidential and shall not publish or otherwise disclose and
shall not use for any purpose any Confidential Information furnished to it by
the other party or developed pursuant to this Agreement; provided, however, that
after the expiration or termination of this Agreement, either party shall be
free to exploit commercially in any manner any proprietary information and
technology which belongs solely or jointly to it.

            7.2 Authorized Disclosure. Each party may disclose Confidential
Information of the other party to its employees, agents or Affiliates (i) who
are required to know such information in connection with the permitted use of
such information 


                                     - 9 -
<PAGE>   10
hereunder and (ii) who are bound by customary non-use and confidentiality
obligations as set forth in this Section 7.

financial terms contained in Section 3.1 of this Agreement shall be
considered Confidential Information hereunder.

      8.    TERMINATION AND REVERSION OF TECHNOLOGY.

            8.1 Mutual Termination. The parties hereto may terminate this
Agreement by mutual consent. Such termination shall be effective 60 days after
such a determination or upon such other date as the parties may mutually agree.

            8.2 Termination of Licenses Without Cause. BMI may terminate and
revert its licenses and all right to make, use or sell under this Agreement at
any time upon *** prior written notice. Such reversion shall be free of any
continuing lien on, or grant of any right or interest in, the Products or
Technical Information. In the event of such termination, no further payments
relating to the Products shall accrue or be due under this Agreement subsequent
to the effective date of such termination; provided, however, that BMI shall pay
to CollaGenex any royalties accrued on sales prior to the effective date of the
termination of the license.

            8.3 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 cure such default. If the
party receiving such notice disagrees with the existence, extent or nature of
the default, the issue shall be referred to arbitration pursuant to Section 9.10
for a decision regarding the existence, extent or nature of the default, cure
and remedy therefor. If such default is not cured within 60 days or after the
determination pursuant to arbitration (or, if such default cannot be cured
within such 60 day period and the party in default does not commence and
diligently continue actions to cure 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.

            8.4 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 or 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

material breach of this Agreement by BMI, BMI shall have the right to complete
all work in progress and for one year (or such longer period as the parties may
reasonably agree) to dispose of all Products or substantially completed Products
then on hand, and royalties shall be paid to CollaGenex with respect to such
Products as though such license had not terminated or expired.

            8.6 Effect of Termination. In the event of any termination of this
Agreement, except as otherwise provided herein, all rights to the Products and
Technical Information shall revert to CollaGenex who shall be free to develop,

paid to CollaGenex all amounts under sections 3.1(i), (ii), and (iii) hereof,
CollaGenex shall become insolvent or bankrupt under applicable U.S. bankruptcy
laws, or shall make an assignment for the benefit of its creditors, or there
shall be appointed a trustee or receiver of CollaGenex or 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 CollaGenex in bankruptcy or
seeking reorganization, liquidation, dissolution, winding-up arrangement,
composition or readjustment of its debts or any other relief under bankruptcy,
insolvency, reorganization 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, distraint or similar process against any substantial part of the
property of CollaGenex, and any such event shall have continued for sixty (60)
days undismissed, unbonded and undischarged (each such event being a "Bankruptcy
Event"), then all amounts thereafter paid by BMI to CollaGenex pursuant to
Section 3.1(a), (b) or (c) hereof shall be used *** .
