Section 4.  Ownership of Papers and Intellectual Property Rights.

exclusive right to ownership, possession and title to all papers, documents,
tapes, drawings, notebooks, formulas, customer lists, software, hardware,
trademarks, trade names, service marks, processes, data, intellectual property,
or other records, information, or products prepared by Employee during
employment with Company or provided by Company, or which otherwise come into

any copies of such items. Employee further agrees to deliver to the Company upon
request all
<PAGE>

such items in Employee's possession and without request to immediately deliver
such items upon the termination, voluntarily or involuntarily, of Employee's
employment.

               (b)  Inventions. The term "Inventions" means all ideas,
inventions, and discoveries, whether patentable, copyrightable, or not, relating
to any present or prospective business of the Company, including but not limited
to software, algorithms, designs, devices, processes, methods, formulae,
techniques, software, data storage systems, networks, servers, and any
improvements to the foregoing.

                    (i)    Report. Employee agrees to promptly disclose all
Inventions made or conceived by the Employee, whether or not during the hours of
his employment or with the use of Company facilities, materials, or personnel,
either solely or jointly with others, during the term of his employment by the
Company. Employee shall inform the Company promptly and fully of such Inventions
by a written report, setting forth in detail the structures, procedures, and
methodology employed and the results achieved. A report shall also be submitted
by the Employee upon completion of any study or research project undertaken on
the Company's behalf, whether or not in the Employee's opinion a given study or
project has resulted in an Invention.

                    (ii)   Assignment and Patent. Employee hereby assigns and
agrees to assign to the Company all of his rights to such Inventions and to all
proprietary rights therein, based thereon or related thereto, including, but not
limited to, applications for United States and foreign letters patent and
resulting letters patent. At the Company's request and expense, the Employee
shall execute such documents and provide such assistance as may be deemed
necessary by the Company of apply for, defend or enforce any United States and
foreign letters patent based on or related to such Inventions. Employee agrees
to execute all documents reasonably requested by Company to assist the Company
in perfecting or protecting any or all of its rights in the Inventions.

                    (iii)  Copyright. Employee acknowledges that all
copyrightable Inventions are "works made for hire" and consequently that the
Company owns all copyrights thereto, including, but not limited to, 17 U.S.C.
Sections 101 and 210. The Company shall have the sole and exclusive right to
register the copyright(s), or its assignees, in all such work in its name as the
owner and author of such work and shall have the exclusive rights conveyed under
17 U.S.C. Sections 106 and 106A, including, but not limited to, the right to
make all uses of the works in which attribution or integrity rights may be
implicated. Additionally, without in any way limiting the foregoing, Employee
hereby assigns, transfers and conveys to Company, its successors, heirs and
assigns, any and all right, title or interest that Employee may now have, or may
acquire in the future, to the work including, but not limited to, all ownership,
patent (United States and foreign letters patent), trade secret, trade names and
trademarks, copyright moral, attribution and/or integrity rights. Employee
hereby expressly and forever waives any and all rights that Employee may have
arising under 17 U.S.C. Section 106A, and any rights arising under any federal
or state laws that convey rights which are similar in nature to those conveyed
under 17 U.S.C. Section 106A. Notwithstanding any provision of the Copyright
Act, any and all copyrightable works, prepared either in whole or in part by
Employee under this agreement, are, shall be, or shall become, owned by the
Company.

Section 5.  Termination of Employment.
            -------------------------

               (a)  Subject to Section 5.(b), either party, with or without
cause, may terminate the employment relationship with fourteen (14) days written
notice ("Required Notice") to the other party. The relationship established
hereunder is employment at will. If Employee fails to give the Required Notice,
Employee shall waive any and all rights he may have to any accrued vacation due
him. In the event either Employee gives the Required Notice or Company gives the
Required Notice, but Company wishes to accelerate termination of Employee's
employment, Company may elect to so accelerate, in Company's sole discretion,
and terminate Employee immediately; provided, however, Company must in all
events pay the Employee for the fourteen (14) day notice period unless the cause
of the termination was for Employee's violation of

                                       2

<PAGE>

Company's rules, regulations and policies, Employee misconduct, Employee neglect
of duties, or Employee's conviction of a felony. The death of Employee shall
automatically terminate this Agreement.

               (b)  The foregoing notwithstanding, in the event that Employee's
employment is terminated by Company other than for Good Cause and prior to the
Company's initial public offering, the Company shall pay to Employee an amount
equal to the Employee's annual compensation in 12 equal monthly installments and
if Employee's employment is terminated by Company other than for Good Cause and
after the Company's initial public offering, the Company shall only pay to
Employee an amount equal to one half (1/2) of the Employee's annual compensation
paid monthly for six months. The term "Good Cause" shall mean Employee's
commitment of an act of dishonesty, conviction of a felony, gross neglect or
material failure to perform Employee's duties hereunder. If the Company proposes
to terminate the employment relationship for Good Cause, the Company shall give
notice to Employee with sufficient particularity that the Employee will have an
opportunity to correct the situation to the reasonable satisfaction of the
Company within a reasonable period of time set forth in the Company notice which
shall not be less than 45 days, provided no notice and cure shall be required
for terminations attributable to dishonesty and conviction of a felony.

Section 6.  Confidentiality and Noncompetition.
            ----------------------------------

          In order for Company to reasonably protect its interests against the
competitive use of any of Company's confidential information or business
relationships, Employee agrees to the following covenants.

               (a)  Covenant Not to Compete. During Employee's employment, and
for a period of one (1) year after Employee's termination of employment, for
whatever reason, Employee shall not, within the continental United States,
directly or indirectly, acting alone or with others, voluntarily or
involuntarily, own, operate, engage in, be interested in, control through stock
ownership or otherwise, or become employed by, work for, advise, be connected
with, consult with or represent in any capacity or in any manner whatsoever in
any role, an individual, firm, corporation, partnership, association or other
entity other than the Company who or which is engaged in a business competitive
with the Company or with the Company's Business.

               (b)  Confidentiality. For purposes of this Agreement,
"Confidential Information" shall mean any communication disclosed to Employee or
known by Employee as a consequence of or through his past, present or
prospective employment or business relationship with Company, not generally
known and available in Company's industry, which constitutes Company's
proprietary and non-public method(s) of doing business, including, but not
limited to, any information related to trade secrets, pricing formulas, know-
how, test data, customer lists, vendor lists, training and operating manuals,
software, and reporting systems. Company and Employee acknowledge that during
Employee's period of employment by Company, Company will furnish Employee with
Confidential Information. Employee agrees both during his employment with the
Company, whether under this Agreement or otherwise, and at all times thereafter,
that Employee, his officers, directors, partners, employees, affiliates, agents,
representatives, or assigns (collectively "representatives") shall keep all
Confidential Information in the strictest confidence and shall not discuss,
publish, communicate, transmit, reproduce, or otherwise disclose such
Confidential Information, in any manner whatsoever, in whole or in part, without
the prior written consent of Company, unless and until such time as the
Confidential Information becomes generally known in Company's industry other
than through breach of this Agreement. Any written consent by Company to
Employee's disclosure of Confidential Information, if given, shall in no way
operate as a waiver of Employee's obligation to maintain the confidential nature
of the material disclosed or to protect and preserve that Confidential
Information from disclosures so that it will receive confidential treatment
thereafter. Employee agrees to reimburse Company for any damages sustained and
costs and expenses, including attorneys' fees, incurred in connection with an
unauthorized disclosure of Confidential Information by Employee, his
representatives, or other any person or persons to whom Employee or his
representatives previously had disclosed Confidential Information.

<PAGE>

               (c)  Non-Solicitation of Customers and Employees. During
Employee's employment and for a period of one (1) year after Employee's
termination of employment, for whatever reason, Employee shall not, either
directly or indirectly: 1) solicit any person or persons employed by or
otherwise associated with Company for the purpose of terminating said employee's
or person's employment relationship or association with Company.

                                       4
<PAGE>

               (d)  Reasonableness of Covenants. Employee acknowledges and
agrees that the covenants and agreements contained in this Section are
reasonable, and Employee agrees he shall not raise any issue of their
reasonableness in any proceeding to enforce such covenants and agreements.
Employee agrees that any violation or breach by Employee and/or his
representatives of this Agreement would cause immediate and irreparable harm to
Company, the exact amount of which will be impossible to ascertain, and for that
reason further agrees that Company shall be entitled, as a matter of right, to
an injunction out of any court of competent jurisdiction, restraining any
further violation or breach of this Agreement by Employee and/or his
representatives, either directly or indirectly, such right to an injunction
being cumulative and in addition to whatever remedies Company may have under
applicable law and/or this Agreement. In the event of any litigation or
arbitration under this agreement, the prevailing party shall be entitled to an
award of all cost of the proceeding or suite, including reasonable attorney's
fees.

Section 7.  Ability to Perform. Employee warrants that Employee's execution and
            ------------------
performance of this Agreement is not restricted or prohibited by any agreement
to which Employee is subject.

Section 8.  Miscellaneous. In case of any conflict or ambiguity in connection
            -------------
with or between this Agreement and any policy manuals, including but not limited
to any employee manuals, employment applications, management instructions or
promises, etc., this Agreement shall control. This Agreement shall inure to the
benefit of and be binding upon the Parties hereto, their successors and assigns.
Company may assign this Agreement. Provided, however, Employee's rights under
this Agreement shall not be assignable, nor shall Employee's obligations be
delegable. This Agreement shall be construed and enforced in accordance with the
laws of the State of Missouri, and the Parties hereby irrevocably and
unequivocally consent to the jurisdiction of the court sitting in the County of
St. Louis, State of Missouri, and waive any defense of an inconvenient forum to
the maintenance of any action or proceeding brought in such court in connection
with this Agreement, any objection to venue with respect to any such action, and
any right of jurisdiction on account of the place of residence or domicile of
any party to such action. If any provision or part thereof of this Agreement is
declared invalid, illegal or unenforceable in any respect, the validity,
legality or enforceability of the remaining provisions of this Agreement, and
any other application thereof, shall not in any way be affected or impaired, and
the Agreement shall be construed in all respects as if such invalid, illegal or
unenforceable provisions are omitted. Any notice or other communication required
or which may be given to any party hereunder shall be in writing and shall be
delivered personally, sent by facsimile transmission, or sent by certified,
registered or express mail, postage prepaid, and shall be deemed given when so
delivered personally, sent by facsimile transmission, or if mailed, two days
after the date of mailing, to the address of such party set forth on the first
page hereof, or to such other address as the parties may indicate in writing.
This writing contains the agreement of the parties with respect to the
employment contemplated herein. No amendments or variations of the terms or
conditions of this Agreement shall be valid unless in writing and signed by the
parties hereto. The headings contained in this Agreement are for convenience
only and shall in no manner be construed as part of the Agreement. The waiver by
either Party of a breach or violation of any provisions of this Agreement shall
not operate as or be construed to be a waiver of any subsequent breach hereof.

     IN WITNESS WHEREOF, the parties hereto have caused this instrument to be
duly executed effective as of the day and year first above written.
