      3 As the  Shares  currently  trade  as a  Unit,  together  with  the  Elan

the  accounts may from time to time have debit  balances.  It is not possible to

corresponding Shares).

Item 4.  Purpose of the Transaction.

      Item 4 of the  Schedule  13D is amended and  restated  in its  entirety as
follows:

      The purpose of the acquisition of the Units (and corresponding  Shares) is
for investment,  and the acquisitions of the Units (and corresponding Shares) by
each of the  Partnerships  and the Managed  Accounts  were made in the  ordinary
course of  business  and were not made for the purpose of  acquiring  control of
Axogen.

      Although no Reporting  Person has any specific plan or proposal to acquire
or dispose of Units (and corresponding  Shares),  consistent with its investment
purpose,  each  Reporting  Person at any time and from time to time may  acquire
additional  Units  (and  corresponding  Shares)  or dispose of any or all of its
Units (and  corresponding  Shares)  depending upon an ongoing  evaluation of the
investment  in  the  Units  (and   corresponding   Shares),   prevailing  market
conditions,  other  investment  opportunities,  liquidity  requirements  of  the
Reporting Person and/or other investment considerations.

      Also,  consistent with their investment  intent, the Reporting Persons may
engage in communications  with one or more  shareholders of Axogen,  one or more
officers  of Axogen,  and/or one or more  members of the board of  directors  of
Axogen regarding Axogen, including but not limited to its operations.

      Except to the extent the foregoing may be deemed a plan or proposal,  none
of the  Reporting  Persons has any plans or proposals  which relate to, or could
result in,  any of the  matters  referred  to in  paragraphs  (a)  through  (j),
inclusive,  of the instructions to Item 4 of Schedule 13D. The Reporting Persons
may,  at any time and from time to time,  review or  reconsider  their  position
and/or change their purpose  and/or  formulate  plans or proposals  with respect
thereto.
