                (2) By executing this Agreement, the Executive hereby agrees to

Merger.

          (e) The Company and the Partnership will reimburse the Executive, in

          (h) To the fullest extent permitted by applicable law, the Executive
shall be indemnified and held harmless by the Company and the Partnership
against any and all judgments, penalties, fines, amounts paid in settlement, and
other reasonable expenses (including, without limitation, reasonable attorneys'

any threatened, pending or completed action, suit or proceeding (whether civil,
criminal, administrative, investigative or other) for any action or omission in
his capacity as a director, officer or employee of the Company or the
Partnership.

          Indemnification under this Section 4(h) shall be in addition to, and

standard of conduct necessary for his indemnification hereunder and under the
provisions of applicable law has been met and (y) a written undertaking by or on
behalf of the Executive to repay the amount advanced if it shall ultimately be
determined by a court that the Executive engaged in conduct which precludes
indemnification under the provisions of such applicable law.  Such written
undertaking in clause (y) shall be accepted by the Company or the Partnership,

financial ability of the Executive to make repayment thereunder.  The Company
and the Partnership shall use commercially reasonable efforts to maintain in
effect for the Term of this Agreement a directors' and officers' liability
insurance policy, with a policy limit of at least $5,000,000, subject to
customary exclusions, with respect to claims made against officers and directors
of the Company or the Partnership; provided, however, the Company or the
                                   --------  -------                    
Partnership, as the case may be, shall be relieved of this obligation to
maintain directors' and officers' liability insurance if, in the good faith
judgment of the Company or the Partnership, it cannot be obtained at a
reasonable cost.

decision shall be final and binding on the Executive and the Company; provided
                                                                      --------

terminate immediately and any vested options issued pursuant to the Company's
Incentive Plan and held by the Executive at termination, will expire ninety (90)

the Executive's bonus for the fiscal year in which the termination occurred.  In
addition, the Company will make payments for one (1) year of all compensation
otherwise payable to the Executive pursuant to this Agreement, including, but
not limited to, base salary, bonus and welfare benefits.  In addition, all of
the Executive's unvested stock options and restricted stock awards will

and shares of restricted stock of the Company previously granted to the
Executive shall become free from all contractual restrictions.

          (d) Subject to Section 6(e) hereof, if the Agreement is terminated by
the Company without Cause or other than by reason of his death or Disability, in
addition to any other remedies available, or if the Executive terminates this
Agreement for Good Reason, the Company and the Partnership shall pay the
Executive, in accordance with regular payroll practices, an amount equal to the
sum of (A) the Executive's then annual base salary for the

a lump sum payment in an amount equal to the Severance Amount.

          (f) Notwithstanding anything in this Section 6 to the contrary if the
Term is terminated for any reason within twenty-four (24) months following the
Merger, the Pre-Merger Awards will immediately vest and remain exercisable in
accordance with their respective terms; provided, however, such pre-Merger

     Exchange Act) of beneficial ownership (within the meaning of Rule 13d-3
     promulgated under the Exchange Act) of fifty (50%) percent or more of the

     liquidation or dissolution of the Company or an agreement for the sale or
     other disposition of all or substantially all of the assets of the Company.

circumstances shall the Executive, upon the termination of his employment
hereunder, be required to seek alternative employment and, in the event that the

received in respect of such employment shall be set-off or in any other way
limit or reduce the obligations of the Company under this Section 6.

including, without limitation, the

accelerated vesting of the Executive's rights with respect to stock options,
restricted stock or any other benefit or compensation, results in the imposition
of an excise tax payable by the Executive under Section 4999 of the Internal
Revenue Code, or any successor or other provision with respect to "excess
parachute payments" within the meaning of Section 280G(b) of the Internal
Revenue Code, the Company shall make a cash payment to the Executive in the
amount of such excise tax (the "Excise Tax Payment") and shall also make a cash
payment to the Executive in an amount equal to the total of federal, state and
local income and excise taxes for which the Executive may be liable on account

          8.   Specific Performance.
               -------------------- 

          (a) The Executive acknowledges that the services to be rendered by him
hereunder are of a special, unique, extraordinary and personal character and
that the Company Affiliates would sustain irreparable harm in the event of a
violation by the Executive of Section 7 hereof.  Therefore, in addition to any
other remedies available, the Company shall be entitled to specific enforcement
and/or an injunction from any court of competent jurisdiction restraining the
Executive from committing or continuing any such violation of this Agreement
without proving actual damages or posting a bond or other security.  Nothing
herein shall be construed as prohibiting the Company from pursuing any other
remedies available to it for such breach or threatened breach, including the
recovery of damages.

          (b) If any of the restrictions on activities of the Executive
contained in Section 7 hereof shall for any reason be held by a court of
competent jurisdiction to be excessively broad, such restrictions shall be
construed so as thereafter to be limited or reduced to be enforceable to the
maximum extent compatible with the applicable law as it shall then appear; it
being understood that by the execution of this Agreement the parties hereto
regard such restrictions as reasonable and compatible with their respective
rights.

          (c) Notwithstanding anything in this Agreement to the contrary, in the
event that the Company fails to make any payment of any amounts or provide any
of the benefits to the Executive when due as called for under Section 6 of this
Agreement and such failure shall continue for twenty (20) days after notice
thereof from the Executive, all restrictions on the activities of the Executive
under Section 7 hereof shall be immediately and permanently terminated.

          9.   Withholding.  The parties agree that all payments to be made to
               -----------                                                    
the Executive by the Company pursuant to the Agreement shall be subject to all
applicable withholding obligations of such company.

          10.  Notices.  All notices required or permitted hereunder shall be in
               -------                                                          
writing and shall be deemed given and received when delivered personally, four
(4) days after being mailed if sent by registered or certified mail, postage
pre-paid, or by one (1) day after delivery if sent by air courier (for next-day
delivery) with evidence of receipt thereof or by facsimile with receipt
confirmed by the addressee.  Such notices shall be addressed respectively:

               If to the Executive, to:

unique services by the Executive, and the Executive's rights and obligations

any breach hereof shall be settled by arbitration in Washington, D.C. by a
single neutral arbitrator in accordance with the Commercial Arbitration Rules of
the American Arbitration Association. Judgment upon any award rendered may be
entered in any court having jurisdiction thereof, except in the event of a
controversy relating to any alleged violation by the Executive of Section 7
hereof, in which case the Company shall be entitled to seek injunctive relief
from a court of competent jurisdiction without the requirement to seek
arbitration.

          (d) The headings of the various sections of this Agreement are for
convenience of reference only and shall not define or limit any of the terms or
provisions hereof.

          (e) The provisions of this Agreement which by their terms call for
performance subsequent to the expiration or termination of the Term shall
survive such expiration or termination.

all costs incurred by the Executive in any proceeding for the successful
enforcement of the terms of this Agreement, including without limitation all
costs of investigation and reasonable attorneys fees and expenses.
