      NOW THEREFORE, in consideration of the premises, the mutual agreements set
forth below and other good and valuable consideration, the receipt and adequacy
of which are hereby acknowledged, the parties agree as follows:

      1. Executive's full-time employment as the Company's President and Chief
Executive Officer shall continue from the date of this Separation Agreement
through the close of business on May 10, 2004 (the "Remaining Term"). During the
Remaining Term, Executive shall continue to serve as the Company's President and
Chief Executive Officer in accordance the provisions of Section 3 of the
Employment Agreement.

      2. Executive agrees to serve as Chairman of the Board until such time as
the Board determines it is appropriate to appoint a new Chairman.

      3. Executive will assist the Company in searching for a Successor CEO.

      4. Executive will serve as a member, and Chairman, of the Executive
Committee of the Board until such time as the Company employs a Successor CEO or
such earlier time as may be determined by the Board. In the event the Company
has not employed a Successor CEO prior to the expiration of the Remaining Term,
the Executive Committee of the Board shall be responsible for the supervision
and direction of the Company's business until such time as the Company employs a
Successor CEO, provided that notwithstanding the foregoing, the Board shall have
the power in its sole discretion to determine the members, powers and role of
the Executive Committee.

      5. It is understood and agreed that the termination of Executive's
employment with the Company is the result of a voluntary resignation by the
Executive and not the result of Good Reason (as defined in the Employment
Agreement) or any breach of the Employment Agreement by the Company.

      6. Executive will continue to receive his current base salary and his
current medical, dental and life insurance benefits during the Remaining Term.
Executive will be entitled to any deferred compensation and other unpaid amounts
and benefits earned and vested prior to the end of the Remaining Term. In
recognition of the accomplishments of Executive and the Company to date during
the Company's current fiscal year ending June 30, 2004, within fifteen (15) days
after the end of the Remaining Term the Company shall pay to Executive a cash
bonus of $216,000. The Company shall be entitled to make all required tax and
other customary withholdings from such cash payment.

      7. Executive shall retain the 10,000 shares of Restricted Stock granted
pursuant to the 2001 Stock Agreement that will have vested under the terms of
the 2001 Stock Agreement as of the end of the Remaining Term. To the extent not
previously done, the Company shall deliver certificates for such 10,000 shares
to Executive and such certificates shall not contain any restrictive legend. The
remaining 15,000 shares of Restricted Stock granted pursuant to the 2001 Stock
Agreement and the entire 200,000 shares of Restricted Stock granted pursuant to
the 2002 Stock Agreement will not have vested as of the end of the Remaining
Term and will be forfeited by Executive back to the Company. The certificates
for such 215,000 unvested shares shall be delivered to the Company together with
any stock powers relating to such certificates executed by Executive. To the
extent necessary Executive will execute and deliver to the Company or its
transfer agent any additional stock powers or other documents required to effect
the forfeiture of such shares to the Company and allow the Company to cancel
such shares. The 2004 Restricted


                                       2

Stock Units shall not be granted to Executive and Executive shall forfeit all
rights he may have in and to the 2004 Restricted Stock Units.

      8. Any options granted to Executive which have not vested in accordance
with their terms as of the last day of the Remaining Term shall terminate and be
of no further force and effect as of the last day of the Remaining Term. Any
options granted to Executive which have vested as of the last day of the
Remaining Term shall remain exercisable in accordance with their terms through
the close of business on November 10, 2004, at which time any of such options
which remain unexercised shall terminate and be of no further force and effect.
Attached hereto as Exhibit A is the vesting schedule of all options held by
Executive. It is agreed that the transfer restrictions set forth in Section 3(f)
of the December 2002 Option Agreement are hereby waived and of no further force
and effect.

      9. In order to acknowledge Executive's forfeiture of certain restricted
stock of Executive's prior employer when he joined the Company and in
recognition of Executive's many valuable contributions to the Company, within
fifteen (15) days after the end of the Remaining Term, the Company shall make a
cash payment of $1,250,000 to Executive. The Company shall be entitled to make
all required tax and other customary withholdings from such lump sum cash
payment.

      10. In consideration of the compensation and benefits provided to
Executive under the Employment Agreement and the additional compensation payable
to Executive under this Separation Agreement, it is agreed that the
non-competition provisions set forth in Section 5(a) of the Employment
Agreement, the confidentiality provisions set forth in Section 5(b) of the
Employment Agreement and the non-solicitation of employees provisions set forth
in Section 5(c) of the Employment Agreement shall remain in full force and
effect in accordance with their terms, provided that the "Non-Compete Period" as
defined in Section 5 (a) of the Employment Agreement and as applicable in
Section 5(c) of the Employment Agreement shall extend through May 10, 2007.

      11. Each party agrees not to directly or indirectly make any disparaging,
untrue or defamatory statements or communications (regardless of medium) about
the other.

      12. Except as provided in the next sentence, the Employment Agreement is
terminated and of no further force and effect as of the date of this Separation
Agreement. Notwithstanding the preceding sentence, the following sections of the
Employment Agreement shall survive in accordance with their terms, as such
sections may be amended by the terms of this Separation Agreement: Sections 3,
5, 7, 8 and 11.

      13. The terms and conditions of this Separation Agreement may not be
altered, amended or modified except by a writing duly executed by both the
Company and Executive.

      14. If any provision of this Separation Agreement or the application
thereof is held invalid by a court of law, the invalid provision shall not
affect any other provision or the application thereof which can be given effect
without the invalid provision or application, and to this end the provisions of
this Separation Agreement are declared to be severable.

      15. Courts situated within the State of New Jersey shall have sole
jurisdiction over any disputes arising out of or concerning this Separation
Agreement. The rights and obligations of the parties under this Separation
Agreement shall be construed and enforced in accordance


                                       3

with, and governed by, the laws of the State of New Jersey without regard to
principles of conflict of laws.

      16. No waiver of any breach of any term or provision of this Separation
Agreement shall be construed to be, nor shall it be, a waiver of any other
breach of this Separation Agreement.

      17. This Separation Agreement contains the entire understanding between
the parties hereto with respect to the subject matter hereof and supersedes any
prior understandings, agreements or representations, written or oral, relating
to the subject matter hereof.

            IN WITNESS WHEREOF, the parties have executed this Release Agreement
as of the date written above.
