Notwithstanding the foregoing, if the letter agreement dated February 2, 1995,
("Letter Agreement") duly signed by Employer and Employee is in effect at the
time of a termination pursuant to this paragraph 5, the Letter Agreement shall
not be affected by such termination unless and only to the extent the terms of
such Letter Agreement expressly so states.

         6.  For purposes of this Agreement, the term disability means that
Employee is substantially unable to discharge her responsibilities to Employer
and its affiliates by reason of physical or mental illness or incapacity,
whether arising out of sickness, accident or otherwise, and shall be evidenced
by the written determination of a qualified medical doctor acceptable to
Employer, which determination shall specify the date and time when such
disability commenced and that it has continued uninterrupted for a period of at
least one hundred eighty (180) days.

         7.  For purposes of the Letter Agreement, the term "For-Cause" and
for purposes of this Agreement, the term default mean that Employee has:

             (a) by intentional actions refused to perform her duties
for Employer as provided by paragraph 3 above. In the event that Employer
determines that Employee has intentionally failed to perform her duties for
Employer as provided in paragraph 3, Employer shall notify Employee in writing
of the reasons for its determination and shall provide Employee a reasonable
period in which to either contest the determination or to correct the defects in
performance; or

             (b) breached or otherwise failed to comply with the 
provisions of paragraph 4 above; or


                                        5






             (c) committed an act of dishonesty, fraud, 
misrepresentation or other acts of moral turpitude which in the reasonable
opinion of the President, CEO causes he/she to conclude that the continuation of
employment is not in the best interest of Employer.

         8.  In the event Employer shall terminate for any reason other 
than as set forth in paragraph 5 above the Employment of Employee earlier than
the expiration of the Initial Term or, in the event the parties agree to renew
the Agreement, earlier than the expiration of any renewal period, or Employer
shall change the location of Employee's primary base or employment from
Columbia, Maryland vicinity without Employee's consent, such termination shall
be deemed to be "without cause" and Employee shall be entitled to all
compensation set forth in paragraph 2 (a), and benefits under paragraph 2 (c) to
the extent allowable under the terms of such benefit plans, for the remaining
balance of the Initial Term or renewal period, as the case may be, without any
condition or restriction other than as expressly set forth in the Agreement.
This shall constitute Employer's sole obligation to Employee in the event of a
termination pursuant to this paragraph 8. This provision shall not apply if the
Employee's termination occurs as a result of the expiration of the Initial Term
or any renewal period without renewal by the parties.

Notwithstanding the foregoing, if the Letter Agreement duly signed by Employer
and Employee is in effect at the time of a termination pursuant to this
paragraph 8, the Letter Agreement shall not be affected by such termination
unless and only to the extent the terms of such Letter Agreement expressly so
states.

delivered by hand delivery or by certified mail, postage prepaid, return receipt
requested. Notices to Employer shall be addressed as follows: Green Spring

and its successors and assigns. Employee shall not assign any part of her rights
and/or duties under this Agreement, unless Employer agrees thereto in writing.

         11. This instrument contains the entire Agreement of the parties.
