Voting Securities);provided, however,that the event described in this paragraph (b) shall not be deemed
to be a Change in Control by virtue of any of the following acquisitions: (A) by

of such Company Voting Securities among the holders thereof immediately prior
to the Business Combination, (B) no person (other than any employee
benefit plan (or related trust) sponsored or maintained by the Surviving
Corporation or the Parent Corporation), is or becomes the beneficial owner,

of more than 20% of the Company Voting Securities as a result of the
acquisition of Company Voting Securities by the Company which reduces the
number of Company Voting Securities outstanding; provided,
that if after such
acquisition by the Company such person becomes the beneficial owner of

a Change in Control occurs, this Agreement shall be null and void as of the
date of such termination of employment; provided, however, that if it is
reasonably demonstrated that such termination (i) was at the request of a
third party who has taken steps reasonably calculated to effect a Change in
Control, or (ii) otherwise arose in connection with or anticipation of a
Change in Control, then for all purposes of this Agreement the Effective Date
shall mean the date immediately prior to the date of such termination.  1.6Eligible

time the Company shall have the opportunity to remedy the conduct, unless the
notice sets forth a later date (which date shall in no event be later than
sixty (60) days after the notice is given); provided, however, that no event
described hereunder shall constitute Good Reason if such event is a result of
an isolated, insubstantial and inadvertent action that is not taken in bad
faith and that is remedied by the Company within ten (10) days after
receipt of the Notice of Termination for Good Reason by the Company from the
Executive.  If the Executive continues to
provide services to the Company after one of the events giving rise to Good

right to terminate his employment at any time during the Protection Period for
Good Reason in connection with such event.  1.8Ineligible

Options).  As soon as practicable
following the occurrence of a Change in Control, the Company shall, subject to
shareholder approval, cause the applicable committee or committees
administering the Equity Plans to grant the Executive additional stock options
(the Replacement Options) to purchase common stock of the Company (or, if the

common stock of the surviving entity). 
The Replacement Options will (i) be granted on substantially the
same terms and conditions as the Cashed-Out Options (including provisions  10


related to the term), (ii) have an exercise
price equal to the greater of (A) the fair market value of the underlying
common stock at the time of grant and (B) the exercise price of the
Cashed-Out Options to which they relate, as adjusted to take into account the
transaction or transactions that resulted in the Change in Control, (iii) relate
to the same number of shares as the Cashed-Out Options (as adjusted to take
into account the transaction or transactions that resulted in the Change in
Control), (iv) vest in accordance with the terms of the schedule of the
Cashed-Out Options to which they relate (excluding any vesting that occurs as a
result of such Change in Control and, for purposes of determining the vesting
schedule, the Replacement Options will be deemed to have been granted at the time
of grant of the Cashed-Out Options to which they relate), and (v) will
remain exercisable for the same period as the Cashed-Out Options would have
been exercisable had they not been terminated. The Replacement Options shall
vest in full as of a Qualifying Termination.Notwithstanding anything to the contrary set forth herein, the
Replacement Options will not vest in connection with a subsequent transaction
(the Subsequent Transaction) following the Change in Control in which such
Replacement Options were granted (the Initial Change in Control) that would
constitute a Change in Control if such Subsequent Transaction merely increases
the percentage ownership of common stock of the Company held by the person or
entity whose initial acquisition of common stock of the Company triggered the
Initial Change in Control.  5.Non-Exclusivity of Rights.  Nothing in this Agreement shall prevent or
limit the Executives continuing or future participation in any plan, program,
policy or practice provided by the Company or a successor company or a
Subsidiary (whichever is the Executives employer) for which the Executive may
qualify, nor shall anything in this Agreement limit or otherwise affect such
rights as the Executive may have under any contract or agreement with the
Company or a successor Company or such Subsidiary.  However, if the Executive receives severance
benefits under this Agreement, the Executive is not also entitled to any
benefit under any other severance plan, program, arrangement or agreement maintained
by the Company or a Subsidiary.  Vested
benefits and other amounts that the Executive is otherwise entitled to receive
under any incentive compensation (including, but not limited to any restricted
stock or stock option agreements), deferred compensation and other benefit
programs listed in Section 1.7(d), life insurance coverage, or any other
plan, policy, practice or program of, or any contract or agreement with, the
Company or a successor Company or such Subsidiary on or after the date of the
Qualifying Termination shall be payable in accordance with the terms of each
such plan, policy, practice, program, contract or agreement, as the case may
be, except as explicitly modified by this Agreement.  6.Full Settlement.The Companys obligation to
make the payments provided for in, and otherwise toperformits obligations
under, this Agreement shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action that the Company may have
against the Executive or others.  In no
event shall the Executive be obligated to seek other employment or take any
other action by way of mitigation of the amounts payable to the Executive under
any of the provisions of this Agreement and, such amounts shall not be reduced,
regardless of whether the Executive obtains other employment.  11


7.CertainAdditionalPayments by the Company.  (a)Anything in this Agreement to
the contrary notwithstanding, in the event it shall bedeterminedthat any payment or distribution (including an
acceleration of vesting, or a lapse of restrictions on amounts otherwise
subject to vesting) by the Company to or for the benefit of the Executive (a Payment)
would be subject to the excise tax imposed by Section 4999 of the Internal
Revenue Code of 1986, as amended (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 (a Gross-Up 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 thereon) and Excise Tax imposed
upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up
Payment equal to the Excise Tax imposed upon the Payment.  (b)Subject to the provisions of
paragraph (c) of this Section 7, all determinations required to be
made under this Section 7, including whether and when a GrossUp Payment
is requiredand the amount of
such Gross-Up Payment and the assumptions to be utilized in arriving at such
determination, shall be madebyone of the
major internationally recognized certified public accounting firms (commonly
referred to, as of the date hereof, as a Big Four firm) designated by the
Executive and approved by the Company (which approval shall not be unreasonably
withheld) (the Accounting Firm), which shall provide detailed supporting
calculations both to the Company and the Executive within fifteen (15) business
days of the receipt of notice from the Executive that there has been a Payment,
or such earlier time as is requested by the Company.  In the event that the Accounting Firm is
serving as accountant or auditor for the individual, entity or group affecting
the change of control, the Executive shall designate another Big Four
accounting firm (subject to the approval of the Company, which approval shall
not be unreasonably withheld) to make the determinations required hereunder
(which accounting firm shall then be referred to as the Accounting Firm hereunder).  All fees and expenses of the Accounting Firm
shall be borne solely by the Company. 
Any Gross-Up Payment, as determined pursuant to this Section 7,
shall be paid by the Company to the Executive within five (5) days of the
receipt of the Accounting Firms determination. 
Any determination by the Accounting Firm shall be binding upon the
Company and the Executive.  As a result
of the uncertainty in the application of Section 4999 of the Code at the
time of the initial determination by the Accounting Firm hereunder, it is
possible that Gross-Up Payments which will not have been made by the Company
should have been made (Underpayment) consistent with the calculations
required to be made hereunder.  In the
event that the Company exhausts its remedies pursuant to paragraph (c) of
this Section 7 and the Executive thereafter is required to make a payment
of any Excise Tax, the Accounting Firm shall determine the amount of the
Underpayment that has occurred and any such Underpayment shall be promptly paid
by the Company to or for the benefit of the Executive.  12


(c)The Executive shall notify
the Company in writing of any claim by the Internal Revenue Service that, if
successful, would require the payment by the Company of the Gross-Up
Payment.  Such notification shall be
given as soon as practicable but no later than ten (10) business days
after the Executive is informed in writing ofsuchclaim and shall
apprise the Company of the nature of such claim and the date on which such
claim is requested to be paid.  The
Executive shall not pay such claim prior to the expiration of the thirty (30)
day period following the date on which the Executive gives such notice to the Company
(or such shorter period ending on the date that any payment of taxes with
respect to such claim is due).  If the
Company notifies the Executive in writing prior to the expiration of such
period that it desires to contest such claim, the Executive shall:  (i)give the Company any information
reasonably requested by the Company relating to such claim,  (ii)take such action in
connection with contesting such claim as the Company shall reasonably request
in writing from time to time, including, without limitation, accepting legal
representation with respect to such claim by an attorney reasonably selected by
the Company,  (iii)cooperate with the Company in
good faith in order effectively to contest such claim, and  (iv)permit the Company to
participate in any proceedings relating to such claim;  PROVIDED, however, that the Company shall bear and
pay directly all costs and expenses (including additional interest and
penalties) incurred in connection with such contest and shall indemnify and
hold the Executive harmless, on an after-tax basis, for any Excise Tax or
income tax (including interest and penalties with respect thereto) imposed as a
result of such representation and payment of costs and expenses.  Without limitation on the foregoing
provisions of this paragraph (c) of Section 7, the Company shall
control all proceedings taken in connection with such contest and, at its sole
option, may pursue or forego any and all administrative appeals, proceedings,
hearings and conferences with the taxing authority in respect of such claim and
may, at its sole option, either direct the Executive to pay the tax claimed and
sue for a refund or contest the claim in any permissible manner, and the
Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more
appellate courts, as the Company shall determine; PROVIDED, however, that if
the Company directs the Executive to pay such claim and sue for a refund, the
Company shall advance the amount of such payment to the Executive, on an
interest-free basis and shall indemnify and hold the Executive harmless, on an
after-tax basis, from any Excise Tax or income tax (including interest or
penalties with respect thereto) imposed with respect to such advance or with
respect to any imputed income with respect to such advance; and PROVIDED,
further, that any extension of the statute of limitations relating to payment
of taxes for the taxable year of the Executive with respect to which such
contested amount is claimed to be due is limited solely to such contested
amount.  Furthermore, the  13


Companys control of the contest shall be limited to
issues with respect to which a Gross-Up Payment would be payable hereunder and
the Executive shall be entitled to settle or contest, as the case may be, any
other issue raised by the Internal Revenue Service or any other taxing
authority.  (d)If, after the receipt by the
Executive of an amount advanced by the Company pursuant to paragraph (c) of
this Section 7, the Executive becomes entitled to receive any refund with
respect to such claim, the Executive shall promptly take all necessary action
to obtain such refund and (subject to the Companys complying with the
requirements of paragraph (c) of this Section 7) upon receipt of such
refund shall promptly pay to the Company the amount of such refund (together
with any interest paid or credited thereon after taxes applicable
thereto).  If after the receipt by the
Executive of an amount advanced by the Company pursuant to paragraph (c) of
this Section 7, a determination is made that theExecutiveshall not be entitled to any refund with respect to
such claim and the Company does not notify the Executive in writing of its
intent to contest such denial of refund prior to the expiration of thirty (30)
days after such determination, then such advance shall be forgiven and shall
not be required to be repaid and the amount of such advance shall offset, to
the extent thereof, the amount of Gross-Up Payment required to be paid.  (e)Notwithstanding anything herein to the
contrary, the Company shall pay all amounts that it is required to pay to or on
behalf of the Executive under the foregoing provisions of this Section 7
not later than the end of the calendar year following (1) the calendar
year in which the related Taxes are remitted to the applicable taxing authority,
or (2) in the case of amounts relating to a claim described in Section 7(c) that
does not result in the remittance of any Taxes, the calendar year in which the
claim is finally settled or otherwise resolved.  8.Certain Additional Agreements under Section 409A.  (a)In the event the payment of
any amounts under this Agreement would be treated as non-qualified deferred
compensation under Section 409A of the Code, such payment will be delayed
for six (6) months after the date of the Executives Qualifying
Termination if required in order to avoid additional tax under Section 409A
of the Code; provided, however, that if the Executive incurs a separation from
service within the meaning of Code section 409A prior to his Qualifying
Termination, then such six (6) month delay period shall commence with the
date of his prior separation from service. If the Executive dies within six (6) months
following a Qualifying Termination (or his prior separation from service, if
applicable), any such delayed payments shall not be further delayed, and shall
be immediately payable to the Executives estate in accordance with the
applicable provisions of this Agreement.  (b)The Company intends that this
Agreement will comply and be administered in accordance with the rules and
requirements of Section 409A of the Code, including the applicable
exemptions thereunder.  The Company will
not take any  14


action that would expose any payment or benefit to the Executive under
this Agreement or under any plan, arrangement or other agreement to the
additional tax imposed under Section 409A of the Code, unless (i) the
Company is obligated to take the action under an agreement, plan or arrangement
to which the Executive is a party, (ii) the Executive requests the action,
(iii) the Company advises the Executive in writing that the action may
result in the imposition of the additional tax and (iv) the Executive
subsequently requests the action in a writing that acknowledges that he will be
responsible for any effect of the action under Section 409A of the
Code.  The Company will hold the
Executive harmless for any action it may take in violation of this paragraph.  (c)It is the parties intention
that the benefits and rights to which the Executive could become entitled in
connection with the termination of employment covered under this Agreement
comply with Section 409A of the Code, including the applicable exemptions
thereunder.  If the Executive or the
Company believes, at any time, that any of such benefit or right does not so
comply, he or it will promptly advise the other party and will negotiate
reasonably and in good faith to amend the terms of such arrangement such that
it complies (with the most limited possible economic effect on the Executive
and on the Company).  (d)Any obligation of the Company to
reimburse the Executive for legal, accounting or any other type of professional
fees shall continue for the Executives life and, if later, until the complete
disposition of all relevant claims.  In
addition, all benefits in the nature of reimbursements or in-kind services
shall comply with the requirements of Treas. Reg. § 1.409A-3(i)(1)(iv) to
the extent applicable.  For this purpose,
(i) the amount of expenses eligible for reimbursement, or benefits
provided, in one calendar year shall not affect the expenses eligible for
reimbursement, or benefits to be provided, in any other calendar year, (ii) the
reimbursement of any expense shall be made promptly, but in no event later than
the last day of the calendar year next following the calendar year in which the
expense was incurred, and (iii) the right to any reimbursement or benefit
shall not be subject to liquidation or exchange for any other benefit.  (e)Each payment made pursuant to Sections 2(a) or
(c) and Sections 3(a) or (c) shall constitute a separate payment
for 409A purposes.  (f)Any payment
made pursuant to this Agreement that would constitute a gross-up payment under
Treasury Regulation 1.409A-3(i)(1)(v) shall be made in accordance with the
timing requirements set forth in that regulation.  9.Termination of Agreement.This Agreement shall remain
in effect from the date hereof until the last day of the twenty-fourth calendar
month following the date of a Change in Control.  Further, upon a Qualifying Termination, this
Agreement shall continue until the Company or its successor shall have fully
performed all of its obligations thereunder with respect to the Executive, with
no future performance being possible. 
This Agreement may be terminated at any time by the Board with the
written consent of the Executive. 
Notwithstanding the foregoing,  15


this Agreement shall automatically terminate upon
cessation of Executives employment with the Company and its Subsidiaries prior
to the Effective Date.  10.Amendment of Agreement.This Agreement may be amended
at any time by the Board with the written consent of the Executive.  11.Construction.Wherever any words are used

they would so apply.  12.Governing Law.  ThisAgreementshall be

its then existing commercial arbitration rules. The arbitration proceedings
shall be conducted in Baltimore, Maryland, unless the parties mutually agree in
writing to a different location. Prior to presiding over any such dispute, any
arbitrator shall be required to consent in writing that he or she shall reach a
final decision within four (4) months after a claim has been filed and
within sixty (60) days after final submission. Any award rendered in the
arbitration may be enforced in any court of competent jurisdiction. Pending the
resolution of any such claim or dispute, the Executive (and his beneficiaries)
shall continue to receive all payments and benefits due under this Agreement or
otherwise, except to the extent that the arbitrators otherwise provide.  14.Successors and Assigns.  (a)This Agreement

shall 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 expressly to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would have
been required to perform it if no such succession had taken place.  As used in this Agreement, Company shall
mean both the Company as defined above and any such successor that assumes and
agrees to perform this Agreement, by
operation of law or otherwise.  15.Director & Officer Insurance and Indemnification.During the
Protection Period and, upon a Qualifying Termination, for so long thereafter as
the Executive could be subject to liability, the Company shall keep in place a
directors and officers liability insurance policy (or policies) providing
comprehensive coverage to the Executive for claims relating to the Executives
service as an employee, officer, or director of the Company, on terms and
conditions  16


no less favorable to the Executive (e.g., with
respect to scope, amounts and deductibles) provided to then-existing officers
and directors of the Company.  The
Company shall indemnify the Executive to the fullest extent permitted by the
general laws of the State of Maryland and shall provide indemnification
expenses in advance to the extent permitted thereby.  The Company will follow the procedures
required by applicable law in determining persons eligible for indemnification
and in making indemnification payments and advances.   The indemnification and advance of expenses
provided by the Company pursuant to this Agreement shall not be deemed
exclusive of any other rights to which the Executive may be entitled under any
law (common or statutory), or any agreement, vote of stockholders or
disinterested directors or other provision that is consistent with law, both as
to action in his official capacity and as to action in another capacity while
holding office or while employed or acting as agent for the Company, shall
