Item 5. Other Events.

     On April 8, 2004, CollaGenex Pharmaceuticals,  Inc., a Delaware corporation
(the  "Company")  issued a press  release  announcing  that it has  settled  all
pending  litigation  between  the  Company  and  United  Research  Laboratories,
Inc./Mutual Pharmaceutical Company, Inc. ("Mutual").

     In connection  with the  settlement,  the Company and Mutual entered into a
License and Supply Agreement pursuant to which Mutual received a license to sell
a branded version of Periostat(R). Under this agreement, the Company will be the
sole  supplier  of this  product to Mutual,  subject to certain  conditions,  at
prices below the Company's average  manufacturer's price through May 2007 or the
earlier termination of such supply arrangements due to certain circumstances. In
addition,  the  Company  agreed not to grant any  license to sell  Periostat  in
generic trade dress to any third party during the supply term.

     The Company sued Mutual in the United States District Court for the Eastern
District of New York,  alleging that Mutual infringed the Company's  patents for
Periostat for the treatment of adult periodontitis. The Company's complaint also
alleged that Mutual  infringed  the  Company's  patent  rights by  submitting an
Abbreviated New Drug Application ("ANDA") with the Food and Drug Administration,
(the  "FDA")  seeking  FDA  approval  to  market a  generic  tablet  version  of
Periostat.

     In a separate  action in the United States  District Court for the District
of Columbia, the Company sought and, on July 22, 2003, was granted a preliminary
injunction  preventing  the FDA from  approving  generic  versions of Periostat,
including Mutual's version. Mutual intervened in that case.

     In July 2003,  Mutual commenced an action against the Company in the United
States District Court for the Eastern District of  Pennsylvania.  Mutual alleged
that the Company had engaged in an effort to monopolize  the market for low-dose
doxycycline products.

     In the  settlement,  Mutual  agreed  and  confessed  to  judgment  that the
Company's  Periostat  patents are valid and would be infringed by the commercial
manufacture,  use, sale, importation or offer for sale of the generic version of
Periostat for which Mutual  submitted its ANDA.  Mutual  consented to a judgment
enjoining Mutual and any party acting in concert with Mutual from infringing the
Company's patents by making and selling a generic version of Periostat until the
Company's  patents expire or are declared invalid or unenforceable by a court of
competent jurisdiction,  or until Mutual is granted a license under the patents,
which will  occur  under the  License  and Supply  Agreement  if a  third-party,
generic version of Periostat is launched and remains on the market for a certain
period of time or the Company  materially  breaches  its  obligations  under the
agreement.  Finally, Mutual agreed to withdraw from the FDA case in the District
of Columbia.

     The  Company  agreed  to pay to Mutual  the  amount  of  $2,000,000,  which
represents a portion of the anticipated  fees and expenses that the Company will
save as a result of the  settlement  of the pending  actions with  Mutual.  This
charge  will be  recorded  in the first  quarter  of 2004.  Under the  Company's
license agreement with the State University of New York




("SUNY")  covering  Periostat,  the Company is entitled to deduct costs incurred
todefend its patents,  including this payment, from current and future royalties
due SUNY on net sales of Periostat and Mutual's branded version of Periostat.

     A complete  copy of the License and Supply  Agreement is filed  herewith as
Exhibit 10.1 and is incorporated herein by reference.  The foregoing  statements
are qualified in their entirety by the Company's press release,  a complete copy
of which is filed  herewith  as  Exhibit  99.1  and is  incorporated  herein  by
reference.
