                                       4
<PAGE>   5

Relationship as a result of the Executive's Disability, the Company's payment
obligations hereunder shall expire and terminate as of the Date of Termination;
provided, however, that the Company shall be obligated to pay the Executive all
payment obligations accrued and owed to the Executive through the Date of
Termination and shall continue to pay any and all additional payments necessary
to provide the Executive with continuing disability insurance benefits in
accordance with and as provided by Section 2.01(d) hereof.

         b. Termination Upon Death. If the Employment Relationship terminates as
a result of the death of the Executive, the Company's payment obligations
hereunder (including, without limitation, under Sections 2.01(a) and 2.02) shall
expire as of the last day of the month in which the Executive's death occurs;
provided, however, that (i) the Company shall pay to the Executive's estate, as
soon as practicable, any payment obligations accrued hereunder through the date
of the Executive's death; and (ii) for the balance of the Term, the Executive's
wife and children shall be entitled to continue participation in the Company's
group hospitalization, medical, and dental plans (if any), with the full amount
of any premium to be borne by the Company.

         c. Termination for Cause or without Good Reason. In the event the

Executive terminates the Employment Relationship without Good Reason, the
Company shall have no payment or other obligation to Executive whatsoever as of
the Date of Termination or such later specified date, as the case may be;
provided, however, that the Company shall pay the Executive any payment
obligations accrued hereunder through the Date of Termination, or such later
specified date, as the case may be, or that are otherwise required to be made
under the terms of any employee benefit programs in which the Executive is
participating.

         d. Termination Without Cause. In the event the Company terminates the
Employment Relationship without Cause, the Company shall pay to the Executive,
as severance pay in a lump sum, no later than the 30th day following the Date of
Termination, the following amounts:

                  (i)   any payment of Salary (at the rate in effect as of the
Date of Termination) or any Annual Bonus which has accrued, but has not been
paid, through the Date of Termination;

                  (ii)  an Annual Bonus for the fiscal year in which the Date of
Termination occurs, as pro-rated through the Date of Termination. If the amount
of such Annual Bonus cannot be determined by the Board without a review of
financial data unknown to the Board at the Date of Termination, the amount
determined by the Board to be the Annual Bonus for the prior fiscal year shall
be deemed to be the amount of the Annual Bonus for the fiscal year in which the
Date of Termination occurs; and

                  (iii) an amount equal to the product of (A) the sum of the
Salary at the rate in effect as of the Date of Termination, plus the average
Annual Bonus paid to the Executive during the preceding two (2) years (or such
shorter period for which any Annual Bonus has been paid), multiplied by (B) the
number three (3).

                                       5
<PAGE>   6

         The Company shall also continue to provide the Executive with the
employee benefits set forth in Section 2.01 (d), (e), and (f) for the duration
of the Term.

         e. Termination Upon a Change in Control. If the Executive terminates
the Employment Relationship due to a Change in Control, the Company shall pay to
the Executive as severance pay and as liquidated damages (because actual damages
are difficult to ascertain), in a lump sum, in cash, within 30 days after
termination, an amount equal to the amounts described and the cash value of the
employee benefits described in Section 4.03(d) hereof. In addition, if the
Executive is liable for any excise tax (the "BASIC EXCISE TAX") because of
Section 4999 of the Internal Revenue Code of 1986, as amended (the "CODE"), or
any successor or similar provision, with respect to any payments or benefits
received or to be received from the Company or its Affiliates, or any successor
to the Company or its Affiliates, whether provided under this Agreement or
otherwise, the Company shall pay the Executive an amount (the "SPECIAL
REIMBURSEMENT") which, after payment by the Executive (or on the Executive's
behalf) of any federal, state, and local taxes applicable thereto, including,
without limitation, any further excise tax under such Section 4999 of the Code,
on, with respect to or resulting from the Special Reimbursement, equals the net
amount of the Basic Excise Tax. The Company's independent auditors shall make
the determination of the amount of the payment described in this Section
4.03(e).

         f. Employee Benefits. Unless the Company terminates the Employment
Relationship for Cause, or the Executive terminates the Employment Relationship
without Good Reason, the Company shall maintain in full force and effect, for
the continued benefit of the Executive and, if applicable, his wife and
children, the employee benefits set forth in Section 2.01(d), and any
hospitalization, medical, and dental coverage included in 2.01(e) hereof, that
he was entitled to receive immediately prior to the Date of Termination (subject
to the general terms and conditions of the plans and programs under which he
receives such benefits) for the balance of the Term or for the period provided
for under the terms and conditions of such plans and programs, whichever is
longer, with the full amount of any applicable premiums to be borne by the
Company.

         4.04 Termination and Expiration of Agreement. Although the Employment
Relationship may be terminated, this Agreement shall not terminate prior to the
expiration of the Term except upon the prior written consent of both the Company
and the Executive. Upon the expiration or termination of the Term, all rights
and obligations of the parties hereto shall cease and expire, subject to any
provisions to the contrary in Articles 5 and 6.

agreements and covenants set forth in this Article 5; (d) the Company is
employing the Executive because of his expertise and skill in the Company's
business, and thus, would be at a substantial competitive disadvantage if it
fails to acquire exclusive ownership of any and all Executive Inventions
(defined below); and (e) the provisions of this Article 5 are reasonable and
necessary to prevent the improper use or disclosure of Confidential Information
and to enable the Company to acquire sole and exclusive ownership of the
Executive Inventions.

         5.03 Maintaining Confidential Information. In consideration of the
compensation and benefits to be paid or provided to the Executive by the Company
under this Agreement and the acknowledgments set forth above, the Executive,
during the Employment Period and at all times thereafter, agrees and covenants
as follows:

         (a) Company Information. The Executive will hold in strictest
confidence the Confidential Information and will not disclose it to any Person
(defined below) except with the specific prior written consent of the Company or
as may be required by court order, law, government agencies with which the
Company deals in the ordinary course of its business, or except as otherwise
expressly permitted by the terms of this Agreement. Any trade secrets of the
Company will be entitled to all of the protections and benefits afforded under
applicable laws. If any information that the Company deems to be a trade secret
is ruled by a court of competent jurisdiction not to be a trade secret, such
information will, nevertheless, be considered Confidential Information for
purposes of this Agreement. The Executive hereby waives any requirement that the
Company submit proof of the economic value of any trade secret or post a bond or
other security. The Executive will not

                                       7
<PAGE>   8

remove from the Company's premises or record (regardless of the media) any
Confidential Information of the Company or its Affiliates, except to the extent
such removal or recording is necessary for the performance of the Executive's
duties. The Executive acknowledges and agrees that all Confidential Information,
and physical embodiments thereof, whether or not developed by the Executive, are
the exclusive property of the Company or its Affiliates, as the case may be.

                  (b) Third Party Information. The Executive recognizes that the
Company and its Affiliates has received and in the future will receive from
third parties their confidential or proprietary information subject to a duty on
their parts to maintain the confidentiality of such information and to use it
only for certain limited purposes. The Executive agrees that he owes the
Company, its Affiliates, and such third parties, during the Employment Period
and thereafter, a duty to hold all such confidential or proprietary information
in the strictest confidence and not to disclose it to any Person (except as
necessary in carrying out his duties for the Company consistent with the
Company's agreement with such third party) or to use it for the benefit of
anyone other than for the Company or such third party (consistent with the
Company's agreement with such third party) without the express written
authorization of the Company or its Affiliate, as the case may be.

                  (c) Returning Company Documents. The Executive agrees that, at
the time of the termination of his employment with the Company, he will deliver
to the Company (and will not keep in his possession or deliver to any other
Person) any and all devices, records, data, notes, reports, proposals, lists,
correspondence, specifications, drawings, blueprints, sketches, materials,
equipment, other documents or property, or reproductions of any of the
aforementioned items belonging to the Company or any of its Affiliates, and
their respective successors or assigns, regardless of whether such items are
represented in tangible, electronic, digital, magnetic or any other media. In
the event of the termination of his employment, the Executive agrees to sign and
deliver the "TERMINATION CERTIFICATION" attached hereto as Exhibit C.

         5.04 Disputes or Controversies. The Executive recognizes that should a
dispute or controversy arising from or relating to this Agreement be submitted
for adjudication to any court, arbitration panel, or other third party, the
preservation of the secrecy of Confidential Information may be jeopardized. All
pleadings, documents, testimony, and records relating to any such adjudication
will be maintained in secrecy and will be available for inspection by the
Company, the Executive, and their respective attorneys and experts, who will
agree, in advance and in writing, to receive and maintain all such information
in secrecy, except as may be limited by them in writing.

         5.05 Executive Inventions. The Executive will promptly disclose in
writing to the Company as set forth below complete information concerning each
and every invention, discovery, improvement, device, design, apparatus,
practice, process, method, product, computer program or database, whether or not
patentable or copyrightable, made, developed, perfected, devised, conceived,
produced, created or first reduced to practice by the Executive, during the term
of the Executive's employment with the Company, during working hours with the
Company or using the Company's property, facilities or resources or which relate
either directly or indirectly to the services, programs, software, products or
other applications of the Company developed or being developed

                                       8
<PAGE>   9

by the Company which are known to the Executive ("EXECUTIVE INVENTIONS"). The
Executive acknowledges that any and all of said Executive Inventions are the
property of the Company and hereby assigns and agrees to assign to the Company
any and all of my right, title and interest in and to any and all of such
Executive Inventions. The Executive will execute any documents requested by the
Company (which shall be prepared at the Company's expense), including but not
limited to patent and copyright applications and registrations, and will perform
any and all further acts deemed necessary or desirable by the Company in order
to confirm, exploit, or enforce the rights herein granted and assigned by the
Executive to the Company. The provisions of this Section 5.05 shall not apply to
any Executive Invention meeting each of the following conditions: (i) such
Executive Invention was developed entirely on the Executive's own time, (ii)
such Executive Invention was made without the use of any Company equipment,
supplies, facility or Confidential Information, (iii) such Executive Invention
does not relate to any service, program, software, product or other application
of the Company in place or planned during the term of the Executive's employment
or to any research or development efforts of the Company during such term which
are known to the Executive, and (iv) such Executive Invention does not result
from any work or service performed by the Executive on behalf of, or for the
Company. The Executive will promptly disclose all Executive Inventions to the
Board and perform all actions reasonably requested by the Board to establish and
confirm ownership thereof by the Company. Executive Inventions shall not include
the inventions, discoveries, improvements, devices, designs, apparatus,
practices, processes, methods, products, computer programs or databases, listed
on Exhibit D attached hereto.

Article 6:  NON-COMPETITION AND NON-INTERFERENCE

         6.01 Covenants Regarding Competitive Protection. The Company and the
Executive hereby mutually agree that the nature of the Company's business and
the Executive's employment hereunder are based on the Company's goodwill, public
perception, and customer relations. Therefore, in consideration of the
acknowledgments set forth in Section 5.02 herein and the compensation and
benefits to be paid to the Executive pursuant to this Agreement, in particular
the termination pay provided for in Section 4.03 of this Agreement, the
Executive hereby agrees and covenants to each and all of the following:

                  (a) Noncompete. During the Employment Period and the
Post-Employment Period (defined below), the Executive will not, directly or
indirectly, in any capacity whatsoever, individually or on behalf of any other
person or entity, engage or invest in, own, manage, operate, finance, control,
or participate in the ownership, management, operation, financing, or control
of, be employed by, associated with, or in any manner connected with, lend the
Executive's name or any similar name to, lend the Executive's credit to or
render services or advice to, any business engaged or about to become engaged in
the Business (defined below) of the Company, or any of its Affiliates, in the
Market Area. For purposes of this Agreement, the "BUSINESS" of the Company, or
its Affiliates, includes all those businesses, products, and services that are
presently or hereafter marketed by the Company, or its Affiliates, or that are
in the development stage on the Date of Termination (as defined herein); and any
other business in which the Company, or any of its Affiliates, are engaged on
the Date of Termination.

                                       9
<PAGE>   10

                  (b) Solicitation of Customers. During the Employment Period
and the Post-Employment Period, the Executive hereby covenants and agrees that
he will not, either directly or through an Affiliate, solicit any Person that is
a Current Customer (defined below) of the Company or its Affiliates for purposes
of selling products or services to such Person that are in competition with the
products and services offered or sold by the Company or its Affiliates.

                  (c) Solicitation of Employees. During the Employment Period
and the Post-Employment Period, the Executive hereby agrees not to employ,
either directly or through an Affiliate, any current employee of the Company or
its Affiliates or any individual who was an employee of the Company or its
Affiliates during the 12 months immediately preceding the Date of Termination,
and agrees not to solicit, or contact in any manner that could reasonably be
construed as a solicitation, either directly or through an Affiliate, any
employee of the Company or its Affiliates for the purpose of encouraging such
employee to leave or terminate his or her employment with the Company or its
Affiliates.

                  (d) Solicitation of Vendors. During the Employment Period and
the Post-Employment Period, the Executive hereby agrees not to solicit, either
directly or through an Affiliate, a current vendor or supplier of the Company or
its Affiliates for purposes of encouraging such vendor or supplier to cease or
diminish providing products or services to the Company or its Affiliates, or to
change adversely the terms under which such vendor or supplier provides such
products or services to the Company or its Affiliates.

                  (e) Interference. During the Employment Period and the
Post-Employment Period, the Executive hereby agrees not to interfere with the
Company's relationship with any person who at the relevant time is an employee,
contractor, supplier, or customer of the Company or its Affiliates.

                  (f) Post-Employment Period. For purposes of this Section 6.01,
the term "POST-EMPLOYMENT PERIOD" means the one-year period beginning on the
Date of Termination.

                  (g) Market Area. For purposes of this Section 6.01, the term
"MARKET AREA" means the United States of America.

         6.02 Scope. The Executive acknowledges and agrees that the Company is
engaged in or intends to be engaged in business throughout the United States and
that the marketplace for the Company's businesses, products and services is
nationwide, and thus the geographic area, length and scope of the restrictions
contained in Section 6.01 are reasonable and necessary to protect the legitimate
business interests of the Company. The length of the agreements contained in
Sections 6.01 shall be extended for the amount of any time of any violation
thereof and the time, if greater, necessary to enforce such provisions or obtain
any relief or damages for such violation through the court system or
arbitration. The Company may, at any time on written notice approved by its
Board, reduce the geographic area, length or scope of any restrictions contained
in Section 6.01 and,

                                       10
<PAGE>   11

thereafter, the Executive shall comply with the restriction as so reduced,
subject to subsequent reductions. If any covenant in Section 6.01 of this
Agreement is held to be unreasonable, arbitrary, or against public policy, such
covenant will be considered to be divisible with respect to scope, time, and
geographic area, and such lesser scope, time, or geographic area, or all of
them, as an arbitrator or a court of competent jurisdiction may determine to be
reasonable, not arbitrary, and not against public policy, will be effective,
binding, and enforceable against the Executive. In the event of termination of
the Executive's employment with the Company for any reason, the Executive
consents to the Company communicating with my new Company, any entity in the
Business or through or in connection with which the Executive is restricted
hereunder or other party about the restrictions and obligations imposed on the
Executive under this Agreement.

Article 7:  INDEMNIFICATION

         7.1 Claims Arising from the Executive's Position with the Company. In
addition to any separate agreements between the Executive and the Company
relating to indemnification, the Company will indemnify and hold harmless the
Executive, to the fullest extent permitted by applicable law, in respect of any
liability, damage, cost or expense (including reasonable counsel fees) incurred
in connection with the defense of any claim, action, suit or proceeding, or
threatened claim action suit or proceed, to which he is a party, by reason of
his being or having been an officer or director of the Company or any subsidiary
or Affiliate of the Company, or his serving or having served at the request of
the Company as a director, officer, employee or agent of another corporation or
of a partnership, joint venture, trust, business organization, enterprise or
other entity, including service with respect to employee benefit plans. Without
limiting the generality of the foregoing, the Company will pay the expenses
(including reasonable counsel fees) of defending any such claim, action, suit or
proceeding in advance of its final disposition.

         7.02 Contests of this Agreement. The Company agrees to pay promptly, to
the full extent permitted by law, all legal fees and expenses which the
Executive may reasonably incur as a result of any contest in which the Executive
shall be the prevailing party by the Company, the Executive or others of the
validity or enforceability of, or liability under any provision of this
Agreement or any guarantee of performance thereof (including as a result of any
contest by the Executive about the amount of any payment pursuant to this
Agreement), plus in each case interest on any delayed payment at the applicable
Federal rate provided for in Section 7872(f)(2)(A) of the Code.

         7.03 Liability Insurance. During the Employment Period, the Company
agrees to continue on the Executive's behalf, directors and officers insurance
or any other indemnity policy presently carried on behalf of the Executive, and
further agrees to supplement any such existing policy to cover all actions taken
by the Executive in connection with his employment by the Company.

Article 8:  GENERAL PROVISIONS

         8.01 Injunctive Relief and Additional Remedy. The Executive
acknowledges that the injury that would be suffered by the Company as a result
of a breach of the provisions of Articles 5 and 6

                                       11
<PAGE>   12

hereof might be irreparable and that an award of monetary damages to the Company
for such a breach would be an inadequate remedy. Consequently, the Company will
have the right, in addition to any other rights it may have, to obtain
injunctive relief to restrain any breach or threatened breach or otherwise to
specifically enforce the provisions of Articles 5 and 6 hereof.

         8.02 Covenants of Articles 5 and 6 are Essential and Independent
Covenants. The covenants by the Executive in Articles 5 and 6 are essential
elements of this Agreement, and without the Executive's agreement to comply with
such covenants, the Company would not have entered into this Agreement or
employed or continued the employment of the Executive. The Company and the
Executive have independently consulted their respective counsel and have been
advised in all respects concerning the reasonableness and propriety of such
covenants, with specific regard to the nature of the business conducted by the
Company. If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Articles 5 and 6.

         8.03 Representations and Warranties by the Executive. The Executive
represents and warrants to the Company that (a) the Executive has never taken
any action of the types set forth in Section 6.01 and (b) the execution and
delivery by the Executive of this Agreement does not, and the performance by the
Executive of the Executive's obligations hereunder will not, with or without the
giving of notice or the passage of time, or both: (i) violate any judgment,
writ, injunction, or order of any court, arbitrator, or governmental agency
applicable to the Executive; or (ii) conflict with, result in the breach of any
provisions of or the termination of, or constitute a default under, any
agreement to which the Executive is a party or by which the Executive is or may
be bound.

         8.04 Obligations Contingent on Performance. The obligations of the
Company hereunder, including its obligation to pay the compensation provided for
herein, are contingent upon the Executive's performance of the Executive's
obligations hereunder.

         8.05 Binding Effect; Delegation of Duties Prohibited. This Agreement
shall inure to the benefit of, and shall be binding upon, the parties hereto and
their respective successors, assigns, heirs, and legal representatives,
including any entity with which the Company may merge or consolidate or to which
all or substantially all of its assets may be transferred. The covenants of the
Executive under this Agreement, being personal, may not be delegated.

         8.06 Notices. All notices, consents, waivers, and other communications
under this Agreement must be in writing and will be deemed to have been duly
delivered when (a) delivered by hand (with written confirmation of receipt), (b)
sent by facsimile (with written confirmation of receipt), provided that a copy
is mailed by registered mail, return receipt requested, or (c) when received by
the addressee, if sent by a nationally recognized overnight delivery service

         8.10 Severability. If any provision of this Agreement is held invalid
or unenforceable by an arbitrator or any court of competent jurisdiction, the
other provisions of this Agreement will remain in full force and effect. Any
provision of this Agreement held invalid or unenforceable only in part or degree
will remain in full force and effect to the extent not held invalid or
unenforceable.

         8.11 Counterparts. This Agreement may be executed in one or more

Agreement and all of which, when taken together, will be deemed to constitute

breach of this Agreement or investigation thereof pending resolution of such
matter.

         8.14 Arbitration. Any controversy or claim arising out of or relating
to this Agreement, or violation of this Agreement, shall be settled by
arbitration in accordance with the Rules of the American Arbitration
Association, and judgment rendered by the arbitrator may be entered in any court
having jurisdiction thereover. The arbitration shall be conducted in the city of
the Company's principal Executive office at the time such arbitration is
initiated, unless otherwise agreed by the parties thereto. The arbitrator shall
be deemed to possess the power to issue mandatory orders and restraining orders
in connection with such arbitration; provided, however, that nothing in this
Section 8.14 shall be construed as to deny the Company the right and power to
seek and obtain injunctive relief in a court of competent jurisdiction for any
breach or threatened breach of the Company's agreements contained in this
Agreement.
