to satisfy the requirements of Section 8 regarding a Notice of Termination, the
purported termination of the Executives employment pursuant to such Notice of
Termination shall not be effective for purposes of this Agreement.

of Termination any fact or circumstance which contributes to a showing of Good
Reason or Cause shall not waive any right of the Executive or the Company,
respectively, hereunder or preclude the Executive or the Company, respectively,
from asserting any such fact or circumstance in enforcing the Executives or
the Companys rights hereunder.

8.3     Any Notice of Termination for Cause given by the Company must be given
within 90 days of the occurrence of the event(s) or circumstance(s) which

Employment Period, and (ii) within 12 months following the Change in Control
Date, the Executives employment with the Company is terminated by the Company
(other than for Cause) or by the Executive for Good Reason, then, effective
upon the Date of Termination, each outstanding option to purchase shares of

not been terminated, in accordance with the applicable Benefit Plans in effect
on the Effective Date or, if more favorable to the Executive and his family, in
effect generally at any time thereafter with respect to other peer executives
of the Company and its affiliated companies; provided, however, that if the
Executive becomes reemployed with another employer, then the Company shall no
longer be required to provide such benefits to the Executive and his family;

(a)     In the event that the Company undergoes a Change in Ownership or
Control (as defined below, and different from the defined Term Change in
Control), the Company shall, within 30 days after each date on which the
Executive becomes entitled to receive (whether or not then due) a Contingent
Compensation Payment (as defined below) relating to such Change in Ownership or

Compensation Payment, the amount of the Excise Tax with respect to such
Contingent Compensation Payment and the amount of the Gross-Up Payment due to

Executive Response on or before the required date, the Companys initial
determination shall be final. Within 90 days after the due date of each
Contingent Compensation Payment to the Executive, the Company shall pay to the
Executive, in cash, the Gross-Up Payment with respect to such Contingent
Compensation Payment, in the amount determined pursuant to this Section 9.3(a).

in the nature of compensation that is made or made available (under this Agreement or otherwise) to a disqualified individual (as defined in

Section 280G(b)(2)(A)(i) of the Code) on a Change in Ownership or Control of
the Company.

amount of the Excise Tax payable with respect to a Contingent Compensation
Payment and (ii) the amount necessary to pay all additional taxes imposed on
(or economically borne by) the Executive (including the Excise Taxes, state and
federal income taxes and all applicable withholding taxes) attributable to the
receipt of such Gross-Up Payment. For purposes of the preceding sentence, all
taxes attributable to the receipt of the Gross-Up Payment shall be computed
assuming the application of the maximum tax rates provided by law.

all payments or benefits available to the Executive under this Agreement or any
other agreement or plan of the Company under which the Executive receives
Contingent Compensation Payments.

10.     Non-Competition and Non-Solicitation.

10.1     Restricted Activities. While the Executive is employed by the
Company and for a period of two years after the termination or cessation of
such employment for any reason, the Executive will not, directly or indirectly,
in the geographical areas that the Company or any of its subsidiaries does
business or has done business at the time of the Executives departure:

a.    Engage in any business or enterprise (whether as owner, partner,
officer, director, employee, consultant, investor, lender or otherwise, except
as the holder of not more than 1% of the outstanding stock of a publicly-held
company) that is competitive with the Companys business, including but not
limited to any business or enterprise that develops, manufactures, markets, or
sells any product or service that competes with any product or service
developed, manufactured, marketed, sold or provided, or planned to be
developed, manufactured, marketed, sold or provided, by the Company or any of
its subsidiaries while the Executive was employed by the Company; or

b.    Either alone or in association with others (i) solicit, or permit any
organization directly or indirectly controlled by the Executive to solicit, any
employee of the Company to leave the employ of the Company, or (ii) solicit for
employment or permit any organization directly or indirectly controlled by the
Executive to solicit for employment any person who was employed by the Company
at any time during the term of the Executives employment with the Company;
provided, that this clause (ii) shall not apply to any individual whose
employment with the Company has been terminated for a period of six months or
longer.

10.2     Extension. If the Executive violates the provisions of Section 10.1,
the Executive shall continue to be bound by the restrictions set forth in
Section 10.1 until a period of two years has expired without any violation of
such provisions.

10.3     Interpretation. If any restriction set forth in Section 10.1 is
found by any court of competent jurisdiction to be unenforceable because it
extends for too long a period of time or over too great a range of activities or in too broad a geographic
area, it shall be interpreted to extend only over the maximum period of time,
range of activities or geographic area as to which it may be enforceable.

10.4     Equitable Remedies. The restrictions contained in this Section 10
are necessary for the protection of the business and goodwill of the Company
and are considered by the Executive to be reasonable for such purpose. The
Executive agrees that any breach of this Section 10 is likely to cause the
Company substantial and irrevocable damage which is difficult to measure.
Therefore, in the event of any such breach or threatened breach, the Executive
agrees that the Company, in addition to such other remedies which may be
available, shall have the right to obtain an injunction from a court
restraining such a breach or threatened breach and the right to specific
performance of the provisions of this Section 10 and the Executive hereby
waives the adequacy of a remedy at law as a defense to such relief.

11.     Proprietary Information and Developments.

11.1     Proprietary Information.

a.    The Executive agrees that all information, whether or not in writing,
of a private, secret or confidential nature concerning the Companys business,
business relationships or financial affairs (collectively, Proprietary
Information) is and shall be the exclusive property of the Company. By way of
illustration, but not limitation, Proprietary Information may include
inventions, products, processes, methods, techniques, formulas, compositions,
compounds, projects, developments, plans, research data, clinical data,
financial data, personnel data, computer programs, customer and supplier lists,
and contacts at or knowledge of customers or prospective customers of the
Company. The Executive will not disclose any Proprietary Information to any
person or entity other than employees of the Company or use the same for any
purposes (other than in the performance of his or her duties as an employee of
the Company) without written approval by an officer of the Company, either
during or after his or her employment with the Company, unless and until such
Proprietary Information has become public knowledge without fault by the
Executive.

b.    The Executive agrees that all files, letters, memoranda, reports,
records, data, sketches, drawings, laboratory notebooks, program listings, or
other written, photographic, or other tangible material containing Proprietary
Information, whether created by the Executive or others, which shall come into
his or her custody or possession, shall be and are the exclusive property of
the Company to be used by the Executive only in the performance of his or her
duties for the Company. All such materials or copies thereof and all tangible
property of the Company in the custody or possession of the Executive shall be
delivered to the Company, upon the earlier of (i) a request by the Company or
(ii) termination of his or her employment. After such delivery, the Executive
shall not retain any such materials or copies thereof or any such tangible
property.

c.    The Executive agrees that his or her obligation not to disclose or to
use information and materials of the types set forth in paragraphs (a) and (b)
above, and his or her obligation to return materials and tangible property, set

materials and tangible property of customers of the Company or suppliers to the Company or other third parties who may have
disclosed or entrusted the same to the Company or to the Executive.

11.2     Developments.

a.    The Executive will make full and prompt disclosure to the Company of
all inventions, improvements, discoveries, methods, developments, software, and
works of authorship, whether patentable or not, which are created, made,
conceived or reduced to practice by him or her or under his or her direction or
jointly with others during his or her employment by the Company, whether or not
during normal working hours or on the premises of the Company (all of which are
collectively referred to in this Agreement as Developments).

b.    The Executive agrees to assign and does hereby assign to the Company
(or any person or entity designated by the Company) all his or her right, title
and interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications. The Executive also hereby
waives all claims to moral rights in any Developments. However, this paragraph
(b) shall not apply to Developments which do not relate to the present or
planned business or research and development of the Company and which are made
and conceived by the Executive not during normal working hours, not on the
Companys premises and not using the Companys tools, devices, equipment or
Proprietary Information. The Executive understands that, to the extent this
Agreement shall be construed in accordance with the laws of any state which
precludes a requirement in an employee agreement to assign certain classes of
inventions made by an employee, this paragraph (b) shall be interpreted not to
apply to any invention which a court rules and/or the Company agrees falls
within such classes.

c.    The Executive agrees to cooperate fully with the Company, both during
and after his or her employment with the Company, with respect to the
procurement, maintenance and enforcement of copyrights, patents and other
intellectual property rights (both in the United States and foreign countries)
relating to Developments. The Executive shall sign all papers, including,
without limitation, copyright applications, patent applications, declarations,
oaths, formal assignments, assignments of priority rights, and powers of
attorney, which the Company may deem necessary or desirable in order to protect
its rights and interests in any Development. The Executive further agrees that
if the Company is unable, after reasonable effort, to secure the signature of
the Executive on any such papers, any executive officer of the Company shall be
entitled to execute any such papers as the agent and the attorney-in-fact of
the Executive, and the Executive hereby irrevocably designates and appoints
each executive officer of the Company as his or her agent and attorney-in-fact
to execute any such papers on his or her behalf, and to take any and all
actions as the Company may deem necessary or desirable in order to protect its
rights and interests in any Development, under the conditions described in this
sentence.

11.3     United States Government Obligations. The Executive acknowledges
that the Company from time to time may have agreements with other parties or
with the United States Government, or agencies thereof, which impose
obligations or restrictions on the Company regarding inventions made during the
course of work under such agreements or regarding the confidential nature of
such work. The Executive agrees to be bound by all such obligations and restrictions which are made known to the Executive and to take all
appropriate action necessary to discharge the obligations of the Company under
such agreements.

##### 



11.4     Equitable Remedies. The restrictions contained in this Section 11
are necessary for the protection of the business and goodwill of the Company
and are considered by the Executive to be reasonable for such purpose. The
Executive agrees that any breach of this Section 11 is likely to cause the
Company substantial and irrevocable damage which is difficult to measure.
Therefore, in the event of any such breach or threatened breach, the Executive
agrees that the Company, in addition to such other remedies which may be
available, shall have the right to obtain an injunction from a court
restraining such a breach or threatened breach and the right to specific
performance of the provisions of this Section 11 and the Executive hereby
waives the adequacy of a remedy at law as a defense to such relief.

12.     Other Agreements. The Executive represents that his performance of
all the terms of this Agreement and the performance of his duties as an
employee of the Company do not and will not breach any agreement with any prior
employer or other party to which the Executive is a party (including without
limitation any nondisclosure or non-competition agreement). Any agreement to
which the Executive is a party relating to nondisclosure, non-competition or
non-solicitation of employees or customers is listed on Exhibit D attached
hereto.

13.     Successors.

13.1     Successor to Company. The Company shall require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business or assets of the Company expressly
to assume and agree to perform this Agreement to the same extent that the
Company would be required to perform it if no such succession had taken place.
Failure of the Company to obtain an assumption of this Agreement at or prior to
the effectiveness of any succession shall be a breach of this Agreement and
shall constitute Good Reason if the Executive elects to terminate employment,
except that for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be deemed the Date of Termination. As
used in this Agreement, Company shall mean the Company as defined above and
any successor to its business or assets as aforesaid which assumes and agrees
to perform this Agreement, by operation of law or otherwise.

13.2     Successor to Executive. This Agreement shall inure to the benefit of
and be enforceable by the Executives personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees. If the Executive should die while any amount would still be payable
to the Executive or his family hereunder if the Executive had continued to
live, all such amounts, unless otherwise provided herein, shall be paid in
accordance with the terms of this Agreement to the executors, personal
representatives or administrators of the Executives estate.

##### 



14.     Notice. All notices, instructions and other communications given
hereunder or in connection herewith shall be in writing. Any such notice,
instruction or communication shall be sent either (i) by registered or
certified mail, return receipt requested, postage prepaid, or (ii) prepaid via
a reputable nationwide overnight courier service, in each case addressed to the
Company, at 2600 Tower Oaks Boulevard, Rockville, MD 20852, and to the
Executive at 306 Danmark Ct., Millersville, MD 21108-1459 (or to such other address as
either the Company or the Executive may have furnished to the other in writing
in accordance herewith). Any such notice, instruction or communication shall
be deemed to have been delivered five business days after it is sent by
registered or certified mail, return receipt requested, postage prepaid, or one
business day after it is sent via a reputable nationwide overnight courier
service. Either party may give any notice, instruction or other communication
hereunder using any other means, but no such notice, instruction or other
communication shall be deemed to have been duly delivered unless and until it
actually is received by the party for whom it is intended.

15.     Miscellaneous.

15.1     Employment by Subsidiary. For purposes of this Agreement, the
Executives employment with the Company shall not be deemed to have terminated
solely as a result of the Executive continuing to be employed by a wholly-owned
subsidiary of the Company.

15.2     Severability. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

15.3     Injunctive Relief. The Company and the Executive agree that any
breach of Sections 5 and 9 this Agreement by the Company is likely to cause the
Executive substantial and irrevocable damage and therefore, in the event of any
such breach, in addition to such other remedies which may be available, the
Executive shall have the right to specific performance and injunctive relief.

15.4     Governing Law. The validity, interpretation, construction and
performance of this Agreement shall be governed by the internal laws of the
State of Maryland, without regard to conflicts of law principles.

15.5     Waivers. No waiver by the Executive at any time of any breach of, or
compliance with, any provision of this Agreement to be performed by the Company
shall be deemed a waiver of that or any other provision at any subsequent time.

15.6     Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed to be an original but both of which together shall
constitute one and the same instrument.

15.7     Entire Agreement. This Agreement sets forth the entire agreement of
the parties hereto in respect of the subject matter contained herein and
supersedes all prior agreements, promises, covenants, arrangements,
communications, representations or warranties, whether oral or written, by any
officer, employee or representative of any party hereto in respect of the
subject matter contained herein, including, without limitation, that certain
Employment Agreement, dated May 28 ,1998, as amended to date between the
Executive and the Company (the Prior Employment Agreement); provided however,
notwithstanding anything herein to the contrary, for the purposes of the Option
Agreement, dated October 21, 1998, between the Company and the Executive (the
Initial Option Agreement), the definition of Cause as set forth in the
Prior Employment Agreement shall continue to be the definition of Cause under the Initial Option Agreement. Subject to the foregoing, any prior
agreement of the parties hereto in respect of the subject matter contained
herein, including the Prior Employment Agreement, is hereby terminated and
cancelled in all respects. This Agreement does not supersede any option
agreement, indemnification agreement, stock purchase agreement, or any written
incentive compensation, deferred compensation or benefit plan or program which

EXHIBIT B

In January of each year during the Employment Period, the Compensation
Committee of the Board will set a target annual performance bonus (the Target
Bonus) for the Executive. The Executives Target Bonus for the year 2001 is
$80,000. The Executive shall be eligible to receive some or all of this Target
Bonus based upon his achievement of the Performance Goals as described below.
Determining whether the Executive has earned the Target Bonus shall be based on
the following three equally weighted components: (i) achieving the Companys
budgeted revenue target for the year, (ii) achieving the Companys budgeted
earnings per share target for the year, and (iii) achieving specified
management objectives for the year (each a Performance Goal and collectively
the Performance Goals). Each Performance Goal will correspond to, and govern
the payment of, one third (1/3) of the Executives Target Bonus (the
Performance Goal Target Bonus) and will be measured as described below.

If the Executive does not achieve at least 91% of a Performance Goal, then
the Executive will not earn any portion of the related Performance Goal Target
Bonus for that year. If the Executive achieves 110% of a Performance Goal, the
Company shall pay the Executive 200% of the related Performance Goal Target
Bonus for that year, provided that in no event and notwithstanding anything to
the contrary shall the Company be obligated to pay the Executive in the
aggregate a bonus equal to more than 200% of his Target Bonus for any given
year. If the Executive achieves 91% or greater of a Performance Goal, but less
than 110% of a Performance Goal for any given year, the Company shall pay his
related Performance Goal Target Bonus as set forth below:



|Percentage of Performance Goal
Achieved | Percentage of related Performance Goal
TargetBonus to be Paid
|--------------------------------------- | -------------------------------------------------------------
|91%                                     | 10%
