                  -------                                 --------


                                    RECITALS
                                    --------

     A.  The Company desires to retain Employee to provide the services set
forth in this Agreement.

                                   ---------

     In consideration of the promises and the terms and conditions set forth in
this Agreement, the parties agree as follows:

     1.  Employment and Term.
         -------------------

         (a)  Initial Term.  The Company agrees to employ the Employee and the
              ------------
Employee agrees to work for the Company, subject to the terms and conditions
below, for an initial term of two (2) years, beginning June 1, 1998, and ending
May 31, 2000.

         (b)  Renewal.  The term of the Employee's employment shall be extended
              -------
automatically, without further action of either party, as of June 1, 2000, and
on each succeeding anniversary of that date, for terms of one (1) year, unless
on or before ninety (90) days prior to the last day of the term of the
Employee's employment or any extension thereof, the Company or the Employee
shall notify the other in writing of its intention not to renew the Employee's
employment, in which case the Employee's employment shall terminate at the end
of the original term or any extension thereof. If either party notifies the
other of its intention not to renew the Employee's employment less than ninety
(90) days prior to the end of the term of this Agreement or any extension
thereof, then such termination shall be effective ninety (90) days from such
notice. No notice of non-renewal may be given by either party after a renewal
term has commenced. Any such renewal shall be upon such terms and conditions set
forth herein, unless otherwise agreed between the Company and the Employee. The
notice of non-renewal by either party shall not constitute a breach of this
Agreement.

     2.  Compensation; Benefits.  Subject to the terms and conditions of this
         ----------------------
Agreement, the Company shall pay to the Employee a base salary as set forth on
Schedule A, attached hereto and made a part hereof, payable in accordance with
----------
the Company's regular payroll policies.  In addition to this base salary, the
Employee shall be entitled to the benefits and bonuses described on Schedule A,
                                                                    ----------
subject to the terms and conditions described therein.  In addition, the
Employee shall be entitled to receive such other benefits including, but not
limited to, vacation, holidays and sick leave, as the Company generally provides
to its employees holding similar positions as
<PAGE>

that of the Employee. Notwithstanding the foregoing, the Company reserves the
right to adopt, amend or discontinue any employee benefit plan or policy in
accordance with then-applicable law.

     3.  Title; Duties.  The Employee shall be initially employed as President
         -------------
and Chief Executive Officer and shall perform duties that are executive in
nature, consistent with his title. The Company shall not, without Employee's
express written consent, require Employee to be based anywhere other than in
Maryland, except for required travel on the Company's business to an extent
substantially consistent with travel required of persons who hold similar
positions or have similar duties with similar companies.

     4.  Service.  The Employee will devote substantially all his working time
         -------
and efforts to the business and affairs of the Company and will use his best
efforts to discharge the duties assigned to him by the Company. The foregoing
shall not, however, preclude the Employee (a) from engaging in appropriate
civic, charitable, industry or religious activities, (b) from devoting a
reasonable amount of time to private investments and other business activities
arising from such investments (other than any business that is a Competitor (as
defined below) of the Company), (c) from serving on the boards of directors of
other entities, or (d) from providing incidental assistance to family members on
matters of family business, so long as the foregoing activities and service do
not conflict with the Employee's responsibilities to the Company or the terms of
this Agreement.

     5.  Termination by the Company.
         --------------------------

         (a)  General.  The Company shall have the right to terminate this
              -------
Agreement with or without cause at any time during the term of this Agreement by

prior to the date fourteen (14) days following the date of the notice of
termination itself.

         (b)  Cause.  In the event that the Employee is terminated for cause

              ------------
salary and pro rata bonus, if any, due him under this Agreement through the day
on which such termination is effective.

         (c)  Without Cause.  In addition, in the event that the Employee is
              -------------
terminated without cause, the Company shall also pay to the Employee
compensation equal to six (6) months of the Employee's base salary as of the
date of termination.

         (d)  Cause Defined.  For purposes of this Section 5, "cause" shall

hereunder due to mental, physical or other disability for a period of ninety
(90) consecutive business days, as determined in good faith by the Board of
Directors of the Company, or for ninety (90) business days in any period of
twelve (12) consecutive months, this Agreement may be terminated by the Company,
at its option, by written notice to the Employee, effective on the termination
date specified in such notice, provided such termination date shall not be a
date prior to the date of the notice of termination itself. In this case, the
Company will pay the Employee the salary due him through the day on which such
termination is effective.

         (c)  Disability Insurance.  Any amounts paid the Employee pursuant to

         (c)  Cause.  In addition, if the termination is with cause (as defined

     8.  Suspension.  In the event the Company has reasonable cause to believe
         ----------
that there exists cause for termination of this Agreement as defined in
Section 5, immediately upon written notice to the Employee, the Company may, but
---------
shall not be obligated to, suspend the Employee, with pay, for a period not to
exceed two weeks, either as a disciplinary measure or in order to investigate
the Company's belief that such cause exists. No such suspension shall prevent

employed with the Company, the Employee hereby agrees to promptly disclose in
confidence to the Company all inventions, improvements, designs, original works
of authorship, formulas, processes, compositions of matter, computer software
programs, databases, mask works, and trade secrets that are directly related to
the Company's Business (as defined above) ("Inventions"), whether or not
                                            ----------
patentable, copyrightable or protectible as trade secrets, that are made or
conceived or first reduced to practice or created by the Employee, either alone
or jointly with others, during the period of the Employee's employment and in
the course of the Employee's employment.

          (b)  Assignment.  The Employee hereby acknowledges that copyrightable
               ----------
works prepared by the Employee within the scope of the Employee's employment are

and public policies of the State of Maryland are subject to varying
interpretations and change. It is the intention of the Company and of the
Employee that the provisions of this Agreement shall be enforced to the fullest
extent permissible under the laws and public policies of the State of Maryland,
but that the unenforceability (to the modification to conform to such laws or
public policies) of any provision or provisions hereof shall not render
unenforceable, or impair, the

                                       6

remainder of this Agreement. Accordingly, if any provisions of this Agreement

otherwise, except that it shall be binding upon and inure to the benefit of any
successor of the Company and its subsidiaries and affiliates, whether by merger,
reorganization or otherwise, or any purchaser of all or substantially all of the
assets of the Company.

     14.  Notices.  Any notice expressly provided for under this Agreement
          -------
