"Change of Control" shall be deemed to have occurred if:

                           (a) The merger or consolidation of the Company with
                           another corporation where (i) the stockholders of the
                           Company, immediately prior to the merger or
                           consolidation, would not beneficially own,
                           immediately after the merger or consolidation, shares
                           entitling such stockholders to 50% or more of all
                           votes (without consideration of the rights of any

                           vote) to which all stockholders of the surviving
                           corporation would be entitled in the election of
                           directors, and (ii) the members of the Board,

<PAGE>   3

                           (b) The sale or other disposition of all or
                           substantially all the assets of the Company, or a
                           liquidation, dissolution or statutory exchange of the
                           Company.

                           6.2 EFFECT OF A CHANGE OF CONTROL. If a Change of
Control occurs during the Employment Term, Employee's Employment Term shall
terminate 30 days after the Change of Control and it will be treated as a

he will be entitled only to those payments and benefits under that Section.

                  7. COVENANT NOT TO COMPETE. For so long as Employee is
employed by the Company and for a period of eighteen (18) months following the
date Employee ceases to be employed by the Company, to the fullest extent
authorized by law, Employee will not engage in, directly or indirectly, or have
any interest in any person, firm, corporation or business (whether as an
employee, officer, director, agent, security holder, creditor, consultant
shareholder or otherwise) in the United States of America that engages in any
business competitive with the business of the Company; PROVIDED, HOWEVER, that
Employee may own, solely as an investment, not more than one percent (1%) of any
class of securities of any publicly held corporation in competition with the
Company, whose securities are traded on any national securities exchange in the
United States, and may retain ownership interest in such entities. The covenants
in this Section 8 are severable and separate, and the unenforceability of any
specific covenant will not affect the provisions of any other covenant.

                  8. AGREEMENT NOT TO DIVULGE CONFIDENTIAL INFORMATION. Employee
recognizes that by reason of Employee's interest in the Company and its
affiliates and employment or engagement (as an agent, independent contractor,
consultant, director or otherwise) by the Company or its affiliates, Employee
has acquired and will acquire Confidential Information concerning the operations
and business of the Company and its affiliates, the use or disclosure of which
would cause substantial loss and damages that could not be readily calculated
and for which no remedy at law would be adequate. Employee acknowledges and
agrees that any such Confidential Information acquired was and will be received
in confidence from the Company and its respective affiliates, and that all of
such information is the property of the Company and its affiliates. Accordingly,
Employee covenants and agrees with the Company and its affiliates that except in
performance of the Employee's obligations to the Company, or its affiliates or
with the prior written consent of the Company, Employee will not, at any time,
directly or indirectly, (i) disclose any Confidential Information learned by
reason of Employee's past affiliation with the Company or its affiliates or
employment or engagement (as an agent, independent contractor, consultant,
director or otherwise) by the Company or its affiliates; or (ii) use such
information in a manner detrimental to the interest of the Company or its
affiliates unless (x) such information becomes known to the public generally
through no fault of Employee, (y) disclosure is required by law or the order of
any governmental authority or (z) Employee must disclose such information
pursuant to court order in connection with the defense of a lawsuit against the
Employee.

                                       3
<PAGE>   4

Notwithstanding the foregoing, prior to disclosing any information pursuant to
clauses (x), (y) or (z) above, Employee will give prior written notice thereof
to the Company and provide the Company with the opportunity to contest such
disclosure and will cooperate with its efforts to prevent such disclosure. The
term "Confidential Information" includes, without limitation, information not
previously disclosed to the public or to the trade by the Company or its
respective affiliates with respect to their businesses or any products, product
elements, data sources, facilities, trade dress, methods, software, source code,
systems, procedures, manuals, confidential reports, product price list, supplier
arrangement or lists, marketing information, financial information, business
plans, prospects or opportunities or other trade secrets or intellectual
property of any kind or nature.

                  9. AGREEMENT NOT TO SOLICIT OR INTERFERE WITH EMPLOYEES,
SUPPLIERS, AND CUSTOMERS. During the term of Employees' employment with the
Company and for a period of eighteen (18) months thereafter, to the fullest
extent authorized by law, Employee will not, directly or indirectly, or by
acting in concert with others, hire, solicit to hire, or induce or influence any
person who is engaged as an employee, agent, independent contractor, supplier,
consultant, director or otherwise by the Company or any of its affiliates to
leave the employ of the Company or its affiliates (including, without limitation
Company and its subsidiaries) or modify, in any manner adverse to the Company or
any of its affiliates, or to terminate his engagement with the Company or any of
its affiliates or to induce or influence any customer of the Company or any of
its affiliates to terminate or modify his, her or its relationship as a customer
of the Company or any of its affiliates; PROVIDED, HOWEVER, that if requested by
any employee or former employee of the Company or any of its subsidiaries,
Employee may, following written notice to the Vice President of Human Resources
of DBT, provide a reference with respect to such employee.

                  10. TERMINATION OF TERM.

                           (a) DISABILITY. If Employee becomes totally disabled
(as defined below), the Company may terminate the Term and the Company will have
no further liability or obligation to Employee under this Agreement except the
Employee will receive (i) any unpaid Salary that has accrued through the date of
termination and (ii) a pro rata portion of any bonus otherwise payable in
accordance with the provisions of Section 4 for the calendar year in which the
Employee becomes totally disabled. Employee will be deemed to be "totally
disabled" if Employee is considered totally disabled under the Company's group
disability plan in effect at that time, if any, or in the absence of any such
plan, under applicable Social Security regulations.

                           (b) DEATH. If Employee dies during the Term, this
Agreement will automatically terminate, and thereafter the Company will not have
any further liability or obligation under this Agreement to Employee, his
executors, administrators, heirs, assigns or any other person claiming under or
through him except that Employee's estate shall receive any unpaid Salary that
has accrued through the date of termination.
