Executive's signature on any application for patent, copyright, trademark or
other analogous protection or other documents regarding any legal protection
relating to a Development assigned or assignable to the Company under this
Article VI, whether because of Executive's physical or mental incapacity or for
any other reason whatsoever, Executive hereby irrevocably designates and
appoints the Company and its duly authorized officers and agents as his agent
and attorney-in-fact, to act for and in his behalf and stead to execute and file
any such application or applications or other documents and to do all other
lawfully permitted acts to further the prosecution and issuance of patent,
copyright or trademark registrations or any other legal protection thereon with

Executive has produced, composed or written, and which Executive shall produce,
compose or write, individually or in collaboration with others, which arises out
of work delegated to Executive by the Company. Executive agrees that all such

Executive hereby assigns to the Company all his interest in such copyrightable
material and will sign all papers and do all other acts necessary to assist the
Company to obtain copyrights on such material in any and all countries.

Appendix attached hereto, if any, comprise all the Developments that he has made
or conceived prior to his employment by the Company, which Developments are
excluded from this Agreement. Executive understands that it is only necessary to

and confirms that his full, uninhibited and faithful observance of each of the
covenants contained in this Agreement will not cause him any undue hardship,
financial or otherwise, and that enforcement of each of the covenants contained

of the needs of his creditors. The Executive acknowledges and confirms that his
special knowledge of

                                        7

the business of the Company is such as would cause the Company serious injury or
loss if he were to use such ability and knowledge to the benefit of a competitor
or were to compete with the Company in violation of the terms of this Agreement.
The Executive further acknowledges that the restrictions contained in this
Agreement are intended to be, and shall be, for the benefit of and shall be
enforceable by, the Company's successors and assigns.

                               General Provisions
                               ------------------

         13.1 Executive agrees that this Agreement shall be binding upon him

with the Company, or the amount of his wages and/or salary.

cause irreparable damage to the Company and in the event of such breach the

         13.3 This Agreement sets forth the complete, sole and entire agreement
between the parties with respect to the subject matter herein and supersedes any
and all other agreements, negotiations, discussions, proposals, or
understandings, whether oral or written, previously entered into, discussed or
considered by the parties, including that certain Amended and Restated
Employment Agreement that Executive entered into with CELLIT, Inc. on November
19, 1998. Executive represents, warrants and agrees that entering into the
instant Agreement, and the employment relationship with the Company, does not
constitute a termination without cause by CELLIT, Inc. of Executive as that term
is used in the Amended and Restated Employment Agreement. No modification or
variation to this Agreement shall be deemed valid unless in writing and signed
by the Company and Executive.

         13.4 Executive does not have the right to assign or delegate his rights
or obligations hereunder to any other person and this Agreement shall be binding
upon Executive's heirs, executors, administrators and legal representatives. The
Company has the right to assign this Agreement by operation of law or otherwise,
without notice, to any entity which acquires by merger or otherwise a majority
voting interest in Company. This Agreement shall inure to the benefit of the
successors and assigns of the Company.

         13.5 Executive represents and warrants to the Company that he is not
under any obligations to any person, firm, corporation, or other business entity
other than the Company, and has no other interest which is inconsistent or in
conflict with this Agreement, or which would prevent, limit or impair, in any
way, the performance by him of any of the covenants hereunder or his duties in
his employment with the Company. Executive has not entered into, and shall not
enter into, any agreement either oral or written in conflict herewith.

         13.6 Any waiver by either party of a breach of any provision of this
Agreement shall not operate or be construed as a waiver of any subsequent breach
of such provision or any other

                                        8

<PAGE>

provision hereof. In addition, any amendment to or modification of this
Agreement or any waiver of any provision hereof must be in writing and signed by
the Company and Executive.

         13.7 The parties agree that each provision and the subparts of each
provision herein shall be treated as a separate and independent clause, and the
unenforceability of any one clause shall in no way impair the enforceability of
any of the other clauses of the Agreement. Moreover, if one or more of the
provisions contained in this Agreement shall for any reason be held to be
excessively broad as to scope, activity, subject or otherwise, so as to be
unenforceable by law, such provision or provisions shall be construed by the
appropriate judicial body by limiting or reducing it or them, so as to be
enforceable to the maximum extent compatible with the applicable law as it shall
then appear. The parties hereby further agree that the language of all parts of
this agreement shall in all cases be construed as a whole according to its fair
meaning and not strictly for or against either of the parties.

         13.8 The headings contained herein are for the sole purpose of
convenience of reference, and shall not in any way limit or affect the meaning
or interpretation of any of the terms or provisions of this Agreement.

the uniform interpretation and enforcement of its Employment Agreements.

and governed under the internal and domestic laws of such state, without giving
effect to the principles of conflicts of laws of such state.
