  Cephalon,&nbsp;Inc. (the &#147;Company&#148;) received a paragraph IV certification
  notice letter (the &#147;Notice Letter&#148;) relating to an abbreviated new drug
  application (&#147;ANDA&#148;) submitted to the U.S. Food and Drug Administration (the &#147;FDA&#148;)
  by Barr Laboratories,&nbsp;Inc. (&#147;Barr&#148;) requesting approval to market and sell
  a generic version of the Company&#146;s FENTORA&#174; (fentanyl buccal tablet) [C-II]
  product.</font></p>
  
  <p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In its Notice Letter,
  Barr alleges that the U.S. Patent Numbers 6,200,604 and 6,974,590 (the &#147;Patents&#148;),
  which cover methods of use for FENTORA, are invalid, unenforceable and/or will
  not be infringed by Barr&#146;s manufacture, use or sale of the product described in
  its ANDA.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company currently is
  reviewing the Notice Letter and, under the Hatch-Waxman Act, has 45 days to
  initiate a patent infringement lawsuit against Barr.&#160; A patent infringement lawsuit would
  automatically stay the approval by the FDA of Barr&#146;s ANDA until the earlier of
  a district court decision or 30 months from the Company&#146;s receipt of the Notice
  Letter.</font></p>

  Other Events
  .
  On June 10, 2008,
  Cephalon, Inc. (the "Company") received a paragraph IV certification
  notice letter (the "Notice Letter") relating to an abbreviated new drug
  application ("ANDA") submitted to the U.S. Food and Drug Administration (the "FDA")
  by Barr Laboratories, Inc. ("Barr") requesting approval to market and sell
  a generic version of the Company's FENTORA® (fentanyl buccal tablet) [C-II]
  product.
  In its Notice Letter,
  Barr alleges that the U.S. Patent Numbers 6,200,604 and 6,974,590 (the "Patents"),
  which cover methods of use for FENTORA, are invalid, unenforceable and/or will
  not be infringed by Barr's manufacture, use or sale of the product described in
  its ANDA.
  The Company currently is
  reviewing the Notice Letter and, under the Hatch-Waxman Act, has 45 days to
  initiate a patent infringement lawsuit against Barr.  A patent infringement lawsuit would
  automatically stay the approval by the FDA of Barr's ANDA until the earlier of
  a district court decision or 30 months from the Company's receipt of the Notice
  Letter.
  The Company has a
  three-year period of marketing exclusivity for FENTORA that extends until September 2009.  Additionally, the Patents described above
  expire in 2019.
  As previously disclosed in the Company's Current
  Report on Form 8-K filed June 3, 2008, the Company and its
  wholly-owned subsidiary CIMA LABS INC. filed a lawsuit in U.S. District Court
  in Delaware against Watson Laboratories, Inc. and its parent, Watson
  Pharmaceuticals, Inc. (collectively, "Watson"), for infringement of the
  Patents. The lawsuit stems from Watson's filing of an ANDA requesting FDA
  approval to market and sell a generic version of FENTORA.
