         3.       Term. This Agreement is effective when signed by both parties.
The parties agree that Executive's employment may be terminated at any time, for
any reason or for no reason, for cause or not for cause, with or without notice,
by Company or Executive. Upon any such termination, Executive shall return
immediately to Company all documents and other property of Company, together
with all copies thereof, including all Work Product and Proprietary Information,
within Executive's possession or control.

                  For purposes of this Agreement, Work Product shall mean the
data, materials, documentation, computer programs, inventions (whether or not
patentable), and all works of authorship, including all worldwide rights therein
under patent, copyright, trade secret, confidential information, or other
property right, created or developed in whole or in part by Executive while
performing services in furtherance of or related to the Company Business.

                  For purposes of this Agreement, Proprietary Information means
all Trade Secrets and Confidential Information of Company.

                  For purposes of this Agreement, Confidential Information shall
mean Company information in whatever form, other than Trade Secrets, that is of
value to its owner and is treated as confidential.

         4.       Ownership.

                  (a)      All Work Product will be considered work made for
hire by Executive and owned by Company. To the extent that any Work Product may
not by operation of law be considered work made for hire or if ownership of all
rights therein will not vest exclusively in Company, Executive assigns to
Company, now or upon its creation without further consideration, the ownership
of all such Work Product. Company has the right to obtain and hold in its own
name copyrights, patents, registrations, and any other protection available in
the Work Product. Executive agrees to perform any acts as may be reasonably
requested by Company to transfer, perfect, and defend Company's ownership of the
Work Product.

                  (b)      To the extent any materials other than Work Product
are contained in the materials Executive delivers to Company or its Customers,
Executive grants to Company an irrevocable, nonexclusive, worldwide,
royalty-free license to use and distribute (internally or externally) or
authorize others to use and distribute copies of, and prepare derivative works
based upon, such materials and derivative works thereof. Executive agrees that
during his or her employment, any money or other remuneration received by
Executive for services rendered to a Customer belong to Company.

                  For purposes of this Agreement, Customers shall mean any
current customer or prospective customer of Company.

         5.       Trade Secrets and Confidential Information.

                  (a)      Company may disclose to Executive certain Proprietary
Information. Executive agrees that the Proprietary Information is the exclusive
property of Company (or a third party providing such information to Company) and
Company (or such third party) owns all worldwide copyrights, trade secret
rights, confidential information rights, and all other property rights therein.

                  (b)      Company's disclosure of the Proprietary Information
to Executive does not confer upon Executive any license, interest or rights in
or to the Proprietary Information. Except in the performance of services for
Company, Executive will hold in confidence and will not, without Company's prior
written consent, use, reproduce, distribute, transmit, reverse engineer,
decompile, disassemble, or transfer, directly or indirectly, in any form, or for
any purpose, any Proprietary Information communicated or made available by
Company to or received by Executive. Executive agrees to notify Company
immediately if he discovers any unauthorized use or disclosure of the
Proprietary Information.

                  (c)      Executive's obligations under this Agreement with
regard to (i) Trade Secrets shall remain in effect for as long as such
information remains a trade secret under applicable law, and (ii) Confidential
Information shall remain in effect during Executive's employment with Company
and for three years thereafter. These obligations will not apply to the extent
that Executive establishes that the information communicated (1) was already
known to Executive, without an obligation to keep it confidential at the time of
its receipt from Company; (2) was received by Executive in good faith from a
third party lawfully in possession thereof and having no obligation to keep such
information confidential; or (3) was publicly known at the time of its receipt
by Executive or has become publicly known other than by a breach of this
Agreement or other action by Executive.

         6.       Non-Solicitation.

                  A.       Customers. The relationships made or enhanced during
Executive's employment with Company belong to Company. During Executive's
employment and the one year period beginning immediately upon the termination of
Executive's employment with Company for any reason (the "One Year Limitation
Period"), Executive will not, without Company's prior written consent, contact,
solicit or attempt to solicit, on his own or another's behalf, any Customer with
whom Executive had contact in the one year prior to the end of Executive's
employment with Company for any reason (the "One Year Restrictive Period") with
a view of offering, selling or licensing any program, product or service that is
competitive with the Company Business.

                  B. Employees/Independent Contractors. During Executive's
employment and the One Year Limitation Period, Executive will not, without
Company's prior written consent, call upon, solicit, recruit, or assist others
in calling upon, soliciting or recruiting any person who is or was an employee
of Company during the One Year Restrictive Period.

         7.       Acknowledgments. The parties hereto agree that: (i) the
restrictions contained in this Agreement are fair and reasonable in that they
are reasonably required for the protection of Company; (ii) by having access to
information concerning employees and customers of Company, Executive shall
obtain a competitive advantage as to such parties; (iii) the covenants and
agreements of Executive contained in this Agreement are reasonably necessary to
protect the interests of Company in whose favor said covenants and agreements
are imposed in light of the nature of Company's business and the involvement of
Executive in such business; (iv) the restrictions imposed by this Agreement are
not greater than are necessary for the protection of Company in light of the
substantial harm that Company will suffer should Executive breach any of the
provisions of said covenants or agreements and (v) the covenants and agreements
of Executive contained in this Agreement form material consideration for this
Agreement.

         8.       Remedy for Breach. Executive agrees that the remedies at law
of Company for any actual or threatened breach by Executive of the covenants
contained in Sections 4 through 7 of this Agreement would be inadequate and that
Company shall be entitled to specific performance of the covenants in such
paragraphs or injunctive relief against activities in violation of such
paragraphs, or both, by temporary or permanent injunction or other appropriate
judicial remedy, writ or order, in addition to any damages and legal expenses
(including attorney's fees) which Company may be legally entitled to recover.
Executive acknowledges and agrees that the covenants contained in Sections 4
through 7 of this Agreement shall be construed as agreements independent of any
other provision of this or any other agreement between the parties hereto, and
that the existence of any claim or cause of action by Executive

<PAGE>

against Company, whether predicated upon this or any other agreement, shall not
constitute a defense to the enforcement by Company of said covenants.

         9.       No Prior Agreements. Executive hereby represents and warrants
to Company that the execution of this Agreement by Executive and Executive's
employment by Company and the performance of Executive's duties hereunder shall
not violate or be a breach of any agreement with a former employer, client or
any other person or entity.

         10.      Assignment; Binding Effect. Executive understands that
Executive has been selected for employment by Company on the basis of
Executive's personal qualifications, experience and skills. Executive agrees,
therefore, that Executive cannot assign all or any portion of Executive's
performance under this Agreement. Subject to the preceding two (2) sentences and
the express provisions of Section 13. below, this Agreement shall be binding
upon, inure to the benefit of and be enforceable by the parties hereto and their
respective heirs, legal representatives, successors and assigns. The rights and
obligations of Company hereunder shall be available to a successor in interest
of Company, including a successor established for the purpose of converting
Company to a corporation.

         11.      Complete Agreement. This Agreement is not a promise of future
employment. Executive has no oral representations, understandings or agreements
with Company or any of its officers, directors or representatives covering the
same subject matter as this Agreement. This Agreement hereby supersedes any
other employment agreements or understandings, written or oral, between Company
and Executive. This written Agreement is the final, complete and exclusive
statement and expression of the agreement between Company and Executive and of
all the terms of this Agreement, and it cannot be varied, contradicted or
supplemented by evidence of any prior or contemporaneous oral or written
agreements. This written Agreement may not be later modified, except by a
further writing signed by a duly authorized officer of Company and Executive,
and no term of this Agreement may be waived except by writing signed by the
party waiving the benefit of such term.
