further, that if a Change of Control (as defined herein) of the Company shall

Company may be terminated by the Company (i) at any time for Cause or without
Cause; or (ii) if, as a result of the Executive’s incapacity due to physical or
mental illness, the Executive shall have been absent from the full-time
performance of the Executive’s duties with the Company for three (3) consecutive
months (a “Disability”).  The

hereto to the other in accordance with Section 19 hereof.


(c)           As used herein:


(i)            A “Notice of Termination”
shall mean a notice that specifies the Date of Termination and that, in the
case of a termination by the Executive, shall indicate the specific termination
provision in this Agreement relied upon and shall set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination
of the Executive’s employment under the provision so indicated and that, in the
case of a termination by the Company, shall indicate whether such termination
is for Cause or without Cause.


(ii)           The “Date of Termination” with
respect to any purported termination of the Executive’s employment shall mean
(A) if the Executive’s employment is terminated for Disability, thirty (30)
days after Notice of Termination is given (provided that the Executive shall
not have returned to the full-time performance of the Executive’s duties during
such thirty (30) day period), (B) if the Executive’s employment is terminated
by reason of death, then the date thereof, (C) if the Executive’s employment is

employment is terminated for any other reason, the date specified in the Notice

be less than thirty (30) nor more than sixty (60) days from the date such
Notice of Termination is given).


6.             Severance Payments.


(a)           The Company shall pay the Executive
the payments and benefits set forth in this Section 6(a) upon any
termination of the Executive’s employment, including, without limitation, the
nonextension of the Executive’s employment by the Company pursuant to Section
2 hereof, unless such termination is by the Company for Cause, by the
Executive without Constructive Termination or the nonextension of the Executive’s
employment by the Executive pursuant to Section 2 hereof:


(i)            The Company shall pay as severance
pay to the Executive an amount (the “Cash Severance Amount”) equal to
two (2) times the sum of (x) the Executive’s Base Salary at the highest rate in
effect prior to the Date of Termination, plus (y) the full amount of the target
level bonus for which the Executive is eligible (or, if no such target level
bonus exists, the maximum bonus, performance and incentive compensation amounts
for which the Executive is eligible), calculated based upon the bonus period in
which the Date of Termination occurs and annualized to the extent that such
bonus period does not reflect a twelve (12) month period.  The Company shall pay the Cash Severance
Amount over the twenty-four (24) month period immediately following the Date of
Termination (the “Severance Period”), in equal installments as nearly as
practicable, on the normal payroll dates for employees of the Company
generally; provided  that, in the event the aggregate portion of
the Cash Severance Amount



 3
 









payable during the first six (6) months of the
Severance Period would exceed an amount (the “Minimum Amount”) equal to
two (2) times the lesser of (i) the Executive’s annualized compensation as in
effect for the calendar year immediately preceding the calendar year during
which the Executive’s termination of employment occurs, or (ii) the maximum
amount that may be taken into account under a qualified plan pursuant to
Section 401(a)(17) of the Internal Revenue Code of 1986, as amended (the “Code”)
for the calendar year during which the Executive’s termination of employment
occurs, then (x) the Company shall pay a portion of the Cash Severance Amount
equal to the Minimum Amount over the first six (6) months of the Severance Period,
in equal installments as nearly as practicable, on the normal payroll dates for
employees of the Company generally and (y) the Company shall pay the remainder
of the Cash Severance Amount over the remaining eighteen (18) months of the
Severance Period, in equal installments as nearly as practicable, on the normal
payroll dates for employees of the Company generally.  Notwithstanding the foregoing, in the event
the Company terminates the Executive’s employment without Cause or elects not
to extend the Executive’s employment pursuant to Section 2 hereof or the
Executive resigns after a Constructive Termination during the time period
commencing with a written agreement for a Change of Control (which transaction
is ultimately consummated) and ending two (2) years thereafter, the Company
shall pay the Cash Severance Amount in cash in a single lump sum payment within
five (5) days of the Date of Termination; provided  that, in the
event the Cash Severance Amount would exceed the Minimum Amount (as defined
above), then a portion of the Cash Severance Amount equal to the Minimum Amount
shall be paid no later than five (5) days after the Date of Termination, and
the remainder of the Cash Severance Amount shall be paid on the date that is
one business day after the date that is six (6) months after the Date of
Termination.  In no event shall any
payments under this Section 6(a)(i) be made later than December 31 of the
second (2nd) calendar year following the calendar year during which the Date of
Termination occurs.


(ii)           For a twenty-four (24) month period
after the Date of Termination, the Company shall administer and pay for the
Executive’s life, disability, accident and health insurance benefits
substantially similar to those which the Executive is receiving immediately
prior to the Notice of Termination.


(b)           Notwithstanding any contrary
provision in any agreement relating to the grant by the Company or any of its
affiliates of any option to acquire shares of the Company’s or any affiliate’s
capital stock pursuant to such entity’s stock option plans (“Stock Options”)
or the issuance of capital stock or other equity interests of any such entity
pursuant to a restricted stock agreement or similar arrangement (“Restricted
Stock”) (including in each case, without limitation, Stock Options and
Restricted Stock granted under the Company’s Amended and Restated Omnibus 2002
Stock Incentive Plan (the “Plan”)), if such Stock Options or Restricted
Stock held by the Executive are assumed or an equivalent option right
substituted by a successor corporation (or its affiliate) in a Corporate
Transaction (as defined in the Notice of Stock Option Grant or Notice of
Restricted Stock Bonus Award entered into under the Plan) or a Change of
Control (as defined below), then during the period commencing with a written
agreement for such Corporate Transaction or Change of Control (which
transaction is ultimately consummated) and ending two (2) years thereafter the
Company terminates the Executive’s employment without Cause or elects not to
extend the Executive’s employment pursuant to Section 2 hereof or the Executive
resigns after a Constructive Termination, all Stock Options and all shares of
Restricted



 4
 









Stock which have not yet become vested shall become
vested in full on the Date of Termination. 
Stock Options and Restricted Stock not so assumed or substituted by the
successor corporation in such Corporate Transaction shall be treated as
provided in the Plan or the agreements thereunder (or other plans and
agreements applicable to such Stock Options or Restricted Stock, as the case
may be) with respect to Stock Options and Restricted Stock that are not assumed
or substituted in such Corporate Transaction or Change of Control.


(c)           The payments provided in Section
6(a) shall be in addition to the payments and benefits set forth in Section
7 hereof.


7.             Compensation Other than Severance
Payments.  If the Executive’s
employment shall be terminated by him or the Company for any reason, the
Company shall (i) pay the Executive’s normal post-termination compensation and
benefits under, and in accordance with, the Company’s retirement, insurance and
other compensation or benefit plans or programs during such period, (ii) pay
the Executive, no later than five (5) days after the Date of Termination, an
amount in cash equal to (A) the Executive’s accrued but unpaid Base Salary
through the Date of Termination, plus (B) the amount of any unpaid bonus,
performance and incentive compensation which has been earned by the Executive
for any fiscal period preceding the Date of Termination in respect of which
such compensation is paid or payable.


8.             Certain Definitions.


(a)           Cause. “Cause” shall
mean the following:


(i)            A good faith finding by the Board or
the CEO that the Executive (w) has been convicted of a felony, (x) has been
convicted of a misdemeanor (excluding traffic violations) to the extent such
conviction could reasonably be considered to compromise the best interests of
the Company or any of its Subsidiaries or render the Executive unfit or unable
to perform his services and duties hereunder, (y) has committed any other act
or omission involving dishonesty, disloyalty or fraud with respect to the
Company or any of its Subsidiaries or any of their customers or suppliers, or
(z) has committed an act involving unlawful or disreputable conduct in the
context of Executive’s employment which is likely to be harmful to the Company
or its reputation;


(ii)           The continued failure by the
Executive to perform his duties in all material respects for the Company or any
of its Subsidiaries continuing for a period of 45 days following a demand for
such performance by the Board or the CEO or a material breach by the Executive
of his obligations under this Agreement continuing uncured (if curable) for a
period of 45 days following notice from the Board or the CEO (other than any
such failure or breach resulting from the Executive’s incapacity due to
physical or mental illness), which demand shall identify in reasonable detail
the manner that that Executive has not performed his duties or has breached his
obligations (as applicable) and give the Executive an opportunity to respond.
The foregoing shall not be construed to include the Executive’s failure to
achieve financial or operating objectives and goals established by the Board or
the CEO; or


(iii)          A good faith finding by the Board or
the CEO that the Executive

or willful misconduct which has a material adverse effect on the Company or any
of its Subsidiaries.


(b)           Change of Control. A “Change
of Control” shall be deemed to occur if (i) there shall be consummated (x)
any consolidation or merger of the Company in which the Company is not the
continuing or surviving corporation or pursuant to which shares of the Company’s
Common Stock would be converted into cash, securities or other property, other
than a merger of the Company in which the holders of the Company’s Common Stock
immediately prior to the merger hold more than fifty percent (50%) of the
voting power of the surviving corporation immediately after the merger, or (y)
any sale, lease, exchange or other transfer (in one transaction or a series of
related transactions) of all, or substantially all, of the assets of the
Company, or (ii) the stockholders of the Company shall approve any plan or
proposal for liquidation or dissolution of the Company, or (iii) any person (as
such term is used in Section 13(d) and 14(d)(2) of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”)), shall become the beneficial
owner (within the meaning of Rule 13d-3 under the Exchange Act) of fifty
percent (50%) or more of the Company’s outstanding Common Stock other than
pursuant to a plan or arrangement entered into by such person and the Company,
or (iv) within any twenty-four (24) month period, the following individuals
cease for any reason to constitute a majority of the number of directors then
serving on the Board: individuals who, on the date hereof, constitute the Board
and any new director (other than a director whose initial assumption of office
is in connection with an actual or threatened election contest, including but
not limited to a consent solicitation relating to the election of directors of
the Company) whose appointment or election by the Board or nomination for
election by the Company’s shareholders was approved or recommended by a vote of
at least two-thirds (2/3) of the directors then still in office who either were

fully corrected prior to the Date of Termination specified in the Notice of
Termination given in respect thereof:


(i)            The assignment to the Executive of
any duties materially inconsistent with the Executive’s position, authority,
duties or responsibilities (including status, offices, effective titles and
reporting structures) in effect immediately prior to such assignment, or any
other action by the Company which results in the material diminishment of such
position, authority, duties or status as Chief Financial Officer of the Company
or a substantial adverse alteration in the nature or status of the Executive’s responsibilities;


(ii)           The relocation of the Executive’s
principal place of employment to a location outside of the Washington, D.C.
metropolitan area or the Company’s requiring the Executive to be based anywhere

 6
 









relocation thereof) except for required travel on the
Company’s business to an extent substantially consistent with the Executive’s
present business travel obligations; or


(iii)          A material breach of this Agreement by
the Company (which shall in any event include, without limitation, the failure
by the Company to pay to the Executive any portion of the Executive’s then Base
Salary or allocated bonus, incentive or other form of compensation or to pay to
the Executive any portion of an installment of deferred compensation under any
deferred compensation program of the Company, within seven (7) days of the date
such compensation is due, and any reduction in the Base Salary).


The Executive’s right to terminate the Executive’s
employment as a result of Constructive Termination shall not be affected by the
Executive’s incapacity due to physical or mental illness.  The Executive’s termination of employment
shall not be considered to be for Constructive Termination unless the Executive
first provides written notice to the Company within ninety (90) days following
the effective date of such event, and the Company has been provided a period of
at least thirty (30) days after receipt of the Executive’s notice during which
to rescind or otherwise remedy the actions, events, or circumstances described
in the Executive’s notice.


(e)           Subsidiary.  “Subsidiary” shall mean any
corporation of which the Company owns securities having a majority of the
ordinary voting power in electing the board of directors directly or through
one or more subsidiaries.


9.             D&O Insurance;
Indemnification.


(a)           To the fullest extent permitted by
applicable law, the Company shall indemnify the Executive against all expenses
(including reasonable attorneys’ fees), judgments, fines, and amounts paid in
settlement, as actually and reasonably incurred by the Executive in connection
with any threatened or pending action, suit, or proceeding, whether civil,
criminal, administrative, or investigative that the Executive is made a party
to by reason of the fact that he is or was performing services as an officer or
director of the Company. Such indemnification shall continue as to the
Executive even if he has ceased to be an employee, officer, or director of the
Company and shall inure to the benefit of his heirs and estate.


(b)           Any costs, fees or expenses incurred
by the Executive relating to indemnification under the Company’s Certificate of
Incorporation, as amended, or the Company’s Bylaws, as amended, shall be paid
by the Company in advance as soon as practicable but not later than three
business days after receipt of written request of the Executive; provided that
the Executive shall undertake to repay such amount to the extent that it is
ultimately determined by a court of competent jurisdiction that the Executive
is not entitled to indemnification. Subject to applicable law, the Executive’s
right to indemnification or advances from the Company shall be enforceable by
the Executive in any court of competent jurisdiction. The burden of proving that
indemnification or advances are not appropriate shall be on the Company.


(c)           The provisions of this Section 9
are in addition to, and not in derogation of, the indemnification provisions of
the Company’s Certificate of Incorporation, as amended, the



 7
 









Company’s Bylaws, as amended, and the Indemnification
Agreement between the Company and the Executive (the “Indemnification
Agreement”).


10.           No Mitigation. The Company
agrees that, if the Executive’s employment is terminated hereunder, the
Executive is not required to seek other employment or to attempt in any way to
reduce any amounts payable to the Executive by the Company. Furthermore, the
amount of any payment provided hereunder shall not be reduced by any
compensation earned by the Executive.


11.           Confidential Information. The
Executive acknowledges that the information, observations and data obtained by
him while employed by the Company or any Subsidiary (including those obtained
prior to the date of this Agreement concerning the business or affairs of the
Company or any of its Subsidiaries (collectively, “Confidential Information”))
are the property of the Company and such Subsidiaries.  Therefore, the Executive agrees that he shall
not (during his employment with the Company or at any time thereafter) disclose
to any unauthorized person or use for his own purposes any Confidential
Information without the express prior written consent of the Board, unless and
to the extent that the aforementioned matters: (a) become generally known to
and available for use by the public other than as a result of the Executive’s
acts or omissions or (b) are required to be disclosed by judicial process or
law. The Executive shall deliver to the Company at the termination of his
employment, or at any other time the Company may request, all memoranda, notes,
plans, records, reports, computer tapes, printouts and software and other
documents and data (and copies thereof) relating to the Confidential
Information, Work Product (as defined below) or the business of the Company or any
Subsidiary which he may then possess or have under his control.


12.           Inventions and Patents. The
Executive hereby assigns to the Company all right,-title and interest to all
patents and patent applications, all inventions, innovations, improvements, developments,
methods, designs, analyses, drawings, reports and all similar or related
information (in each case whether or not patentable), all copyrights and
copyrightable works, all trade secrets, confidential information and know-how,
and all other intellectual property rights that are conceived, reduced to
practice, developed or made by the Executive while employed by the Company and
its Subsidiaries and that (i) relate to the Company’s or any Subsidiary’s
actual or anticipated business, research and development or existing or future
products or services; or (ii) are conceived, reduced to practice, developed or
made using any material equipment, supplies, facilities, assets or resources of
the Company or any Subsidiary (including but not limited to any intellectual
property rights) (“Work Product”). 
The Executive shall promptly disclose such Work Product to the Board and
perform all actions reasonably requested by the Board (whether during his
employment with the Company or at any time thereafter) to establish and confirm
the Company’s ownership (including, without limitation, assignments, consents,
powers of attorney, applications and other instruments).


13.           Noncompetition.  In further consideration of the compensation
to be paid to the Executive hereunder, the Executive acknowledges that in the
course of his employment with the Company he has become and shall become
familiar with the Company’s trade secrets and with other Confidential
Information concerning the Company and its Subsidiaries and that his services
have been and shall be of special, unique and extraordinary value to the
Company and its



 8
 









Subsidiaries. 
Therefore, the Executive agrees that, during the Executive’s employment
with the Company and for six (6) months thereafter (collectively the “Noncompete
Period”), he shall not, without prior express written consent of the Board,
directly or indirectly (whether for compensation or otherwise) own or hold any
interest in, manage, operate, control, participate in, consult with, render
services for, or in any manner participate in any business engaged in any of
the businesses or services provided by the Company or its Subsidiaries during
the employment with the Company or the Noncompete Period (a “Competing
Company”) or otherwise competing with the businesses of the Company or its
Subsidiaries, either as a general or limited partner, proprietor, common or
preferred shareholder, officer, director, agent, employee, consultant, trustee,
affiliate or otherwise.  The Executive
acknowledges that the Company’s and its affiliates’ businesses are conducted
nationally and internationally and agrees that the provisions in this Section
13 shall operate throughout the United States and the world.  Nothing herein shall prohibit the Executive
from being a passive owner of not more than five percent (5%) of the
outstanding securities of any publicly traded company that constitutes a
Competing Company, so long as the Executive has no active participation in the
business of such company.


14.           Non-Solicitation.  During the Executive’s employment with the
Company and for twelve (12) months thereafter (collectively the “Nonsolicit
Period”), the Executive shall not directly or indirectly through another
entity (i) induce or attempt to induce any employee of the Company or any Subsidiary
to leave the employ of the Company or such Subsidiary, or in any way interfere
with the relationship between the Company or any Subsidiary and any employee
thereof, (ii) hire any person who was an employee of the Company or any
Subsidiary at any time during the twenty-four (24) months preceding the Date of
Termination of the Executive, or (iii) induce or attempt to induce any
customer, developer, client, member, supplier, licensee, licensor, franchisee
or other business relation of the Company or any Subsidiary to cease doing
business with the Company or such Subsidiary, or in any way interfere with the
relationship between any such customer, developer, client, member, supplier,
licensee or business relation and the Company or any Subsidiary (including,
without limitation, making any negative statements or communications about the
Company or any Subsidiary).


15.           Enforcement.  If, at the time of enforcement of any of Sections
11 through 14, a court shall hold that the duration, scope or area
restrictions stated herein are unreasonable under circumstances then existing,
the parties agree that the maximum duration, scope or area reasonable under
such circumstances shall be substituted for the stated duration, scope or area
and that the court shall be allowed to revise the restrictions contained herein
to cover the maximum period, scope and area permitted by law.  Because the Executive’s services are unique
and because he has access to Confidential Information and Work Product, the
parties hereto acknowledge and agree that money damages would not be an
adequate remedy for any breach of this Agreement.  Therefore, in the event of a breach or
threatened breach of this Agreement, the Company or its successors or assigns may,
in addition to other rights and remedies existing in their favor, apply to any
court of competent jurisdiction for specific performance and/or injunctive or
other relief in order to enforce or prevent any violations of the provisions
hereof (without posting a bond or other security).  In addition, in the event of an alleged
breach or violation by the Executive of any of Sections 11 through 14,
the Noncompete Period and the Nonsolicit Period shall be tolled until such
breach or violation has been duly cured. 
The Executive agrees that the restrictions contained in Sections 11
through 14 are reasonable.

16.           Successors; Binding Agreement.


(a)           Successors.  The Company will require any successor
(whether direct or indirect, by purchase, merger, consolidation or otherwise)
to all or substantially all of the business and/or assets of the Company, by
agreement in form and substance reasonably satisfactory to the Executive, to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that the Company would be required to perform it if no such
succession had taken place.  As used in
this Agreement, “Company” shall mean the Company as hereinbefore defined and
any successor to its business and/or assets as aforesaid which executes and
delivers the agreement provided for in this Section 16 or which
otherwise becomes bound by all the terms and provisions of this Agreement by
operation of law.


(b)           Binding Agreement.  This Agreement and all rights of the
Executive hereunder 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 amounts would still be payable to him hereunder if he had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to the Executive’s devisee,
legatee, or other designee or, if there be no such designee, to the Executive’s
estate.


17.           Representations.  The Executive hereby represents and warrants
to the Company that: (a) the execution, delivery and performance of this
Agreement by the Executive and the execution of the Company’s business plan by
the Executive do not and will not conflict with, breach, violate or cause a
default under any agreement, contract or instrument to which the Executive is a
party or any judgment, order or decree to which the Executive is subject, (b)
this Agreement constitutes the legal, valid and binding obligation of the
Executive, enforceable in accordance with its terms, (c) the Executive has not
and will not take any action that will conflict with, violate or cause a breach
of any noncompete, nonsolicitation or confidentiality agreement to which the
Executive is a party or by which the Executive is bound and (d) the Executive
is a resident of the Commonwealth of Virginia. 
The Executive hereby acknowledges and represents that he has carefully
reviewed this Agreement, that he has consulted with independent legal counsel
regarding his rights and obligations under this Agreement (or, after carefully
reviewing this Agreement, was given the opportunity to, but has freely decided
not to, consult with independent legal counsel), and that he fully understands
the terms and conditions contained herein.


18.           Certain Payments.  Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company to or for the benefit of the Executive (whether
paid or payable or distributed or distributable pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional
payments required under this Section 18) (each a “Payment”, and
collectively, “Payments”) would be subject to the excise tax imposed by
Section 4999 of the Code or any interest or penalties are incurred by the
Executive with respect to such excise tax (such excise tax, together with any
such interest and penalties, are hereinafter collectively referred to as the “Excise
Tax”), then the Executive shall be entitled to receive an additional
payment (an “Additional Payment”) in an

amount such that after payment by the Executive of all
taxes (including any interest or penalties imposed with respect to such taxes),
including, without limitation, any income taxes (and any interest and penalties
imposed with respect thereto) and Excise Tax imposed upon the Additional
Payment, the Executive retains an amount of the Additional Payment equal to the
Excise Tax imposed upon the Payments.
