              AMENDED AND RESTATED 1998 INCENTIVE STOCK OPTION PLAN

Section 1.        Purpose of the Plan.
                  -------------------

     This stock option plan (the "Plan") is intended to provide incentives:

     (a) to the officers and other employees of TVI Corporation (the "Company"),
or any present or future parent or subsidiary  of the Company  ("Affiliate")  by
providing them with  opportunities  to purchase stock in the Company pursuant to
options  granted  hereunder  which qualify as "incentive  stock  options"  under
Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") ("ISO"
or "ISOs");

     (b) to officers,  employees,  directors, and consultants of the Company and
any present or future  subsidiaries  by  providing  them with  opportunities  to
purchase stock in the Company pursuant to options granted hereunder which do not
qualify as ISOs ("Non-Qualified Option" or "Non-Qualified Options," collectively
with ISO or ISOs, "Options"); and

     (c) to officers,  employees,  directors, and consultants of the Company and
any present or future  Affiliates  by  providing  them with  either  stock bonus
grants  and/or  restricted  stock  purchase  grants  for  Company  Common  Stock
(collectively, "Stock Grants").

     (d) As used  herein,  the term  "Award"  means any  Option  or Stock  Grant
hereunder.  The terms "parent" and  "subsidiary"  mean "parent  corporation" and
"subsidiary  corporation,"  respectively,  as those terms are defined in Section
424 of the  Code  and  the  Treasury  Regulations  promulgated  thereunder  (the
"Regulations").

Section 2.        Common Stock Subject to the Plan.
                  --------------------------------

     (a) The total number of shares of the authorized but unissued shares of the
common stock,  $.01 par value, of the Company  ("Common Stock") for which Awards
may be granted under the Plan shall not exceed six million  (6,000,000)  shares,
subject to adjustment as provided in Section 13 hereof.

     (b) If an Award granted  hereunder shall expire,  be cancelled or otherwise
terminate for any reason without having been exercised in full, the un-purchased
shares subject thereto shall again be available for subsequent  grants under the
Plan.

     (c) Common Stock  issuable  pursuant to an Award granted under the Plan may
be  subject  to such  restrictions  on  transfer,  repurchase  rights  or  other
restrictions  as shall be  determined  by the Board of  Directors of the Company
(the "Board") (discussed below in Section 3).

Section 3.        Administration of the Plan.
                  --------------------------

     (a) General.  The Plan shall be  administered  by the Board.  However,  the
         -------
Board  may  from  time to  time  appoint  a  committee  to make  recommendations
concerning operation of the Plan or the granting of Awards. The Board may hold a
special  meeting to take  actions  concerning  the Plan,  or it may take actions
concerning the Plan at a regular meeting.

     (b) Powers of the Board.  Subject to the  provisions of the Plan, the Board
         -------------------
shall have sole authority, in its absolute discretion:

               (i) determine  the employees of the Company and its  subsidiaries
          to whom ISOs may be granted,  and to determine  to whom  Non-Qualified
          Options may be granted;

               (ii) determine the time or times at which Awards may be granted;

               (iii)  determine the Award price of shares  subject to each Award
          which  price  shall not be less than the minimum  price  specified  in
          Section 6;

               (iv)  determine  whether  each Award  granted  shall be an ISO, a
          Non-Qualified Option or a Stock Grant;

               (v) determine  (subject to Section 9) the time or times when each
          Option  shall  become  exercisable  and the  duration of the  exercise
          period; and

               (vi) determine whether restrictions such as repurchase Awards are
          to be  imposed  on shares  subject  to Awards  and the  nature of such
          restrictions.

               (vii) to  exercise  such  powers and to perform  such acts as the
          Board deems  necessary or  expedient to promote the best  interests of
          the Company which are not in conflict with the provisions of the Plan.

     (c)  Board   Determinations.   All   determinations,   interpretation   and
          ----------------------
constructions  made by the Board in good faith shall not be subject to review by
any person and shall be final, binding and conclusive on all persons.

Section 4.        Eligibility.
                  -----------

     (a) Options  designated as ISOs may be granted only to employees and others
who may eligible  under the Code  (including  officers who are employees) of the
Company or an  Affiliate.  Non-Qualified  Options may be granted to any officer,
employee, or consultant of the Company or an Affiliate.

     (b) In determining the eligibility of an individual to be granted an Award,
as well as in determining the number of shares to be optioned to any person, the
Board shall take into account the position  and  responsibilities  of the person
being considered,  the nature and value to the Company or an Affiliate of his or
her service and accomplishments,  his or her present and potential  contribution
to the success of the  Company or an  Affiliate,  and such other  factors as the
Board may deem relevant.

     (c) No Option  designated as an ISO shall be granted to any employee of the
Company or an Affiliate if such employee owns, immediately prior to the grant of
an Option,  stock  representing more than 10% of the total combined voting power
of all  classes of stock of the  Company or an  Affiliate,  unless the  purchase
price for the stock under such Option  shall be at least 110% of its fair market
value at the time such Option is granted and the Option, by its terms, shall not
be  exercisable  more  than  five (5)  years  from the  date it is  granted.  In
determining the stock ownership under this paragraph,  the provisions of Section
424(d) of the Code shall be  controlling.  In determining  the fair market value
under this paragraph, the provisions of Section 6 hereof shall apply.

                                       61
<PAGE>

     (d) The maximum  number of shares of Common  Stock with respect to which an
Option may be granted to any employee in any taxable  year of the Company  shall
not exceed  1,300,000  shares,  taking into  account  shares  subject to options
granted and  terminated,  or  repriced,  during such  taxable  year,  subject to
adjustment as provided in Section 13 hereof.

Section 5.        Option Agreement.
                  ----------------

     (a) Each Option  shall be  evidenced  by an option  agreement  (the "Option
Agreement")  duly  executed on behalf of the Company and by the optionee to whom
such Option is granted,  which Option Agreement shall comply with and be subject
to the terms and conditions of the Plan.

     (b) The Option  Agreement  may contain  such other  terms,  provisions  and
conditions which are not inconsistent  with the Plan as may be determined by the
Board, provided that Options designated as ISOs shall meet all of the conditions
for ISOs as defined in Section  422 of the Code.  The date of grant of an Option
shall be as determined  by the Board.  More than one Option may be granted to an
individual.

Section 6.        Option Price.
                  ------------

     (a)  Non-Qualified  Options.  The  Option  price or prices of shares of the
          ----------------------
Company's Common Stock for Options designated as Non-Qualified  Options shall be
as determined by the Board,  but in no event shall the Option price be less than
eighty-five  percent  (85%) of the fair market value of such Common Stock at the
time the Option is granted as  determined  by the Board in  accordance  with the
laws of the  State of  Maryland  or the laws of any  jurisdiction  in which  the
Company or its successors in interest may be organized.

     (b) ISOs.  The  Option  price or prices of shares of the  Company's  Common
         ----
Stock for ISOs shall be the fair market  value of such Common  Stock at the time
the  Option  is  granted  as  determined  by the  Board in  accordance  with the
Regulations promulgated under Section 422 of the Code as follows:

          (i)  If  such  shares  are  then  listed  on any  national  securities
     exchange,  the fair market value shall be the mean between the high and low
     sales  prices,  if any,  on such  exchange  on the date of the grant of the
     Option.

          (ii) If the shares are traded on the NASDAQ National Market,  the fair
     market  value of such  shares  shall be the mean  between  the high and low
     sales  prices,  if any, as reported in the NASDAQ  National  Market for the
     date of the grant of the Option.

          (iii) If the  shares are not then  either  listed on any  exchange  or
     quoted in the NASDAQ  National  Market,  the fair market value shall be the
     average of the "Bid" and "Ask" prices,  if any, as reported in the National
     Daily  Quotation  Service  for the date of the grant of the  Option.  If no
     sales  occurred on the date of the grant,  market value shall be determined
     by taking a weighted  average of the means  between  the highest and lowest
     sales prices or Bid/Ask  prices as  appropriate  on the nearest date before
     and the nearest date after the date of grant in  accordance  with  Treasury
     Regulations Section 25.2512-2.

     (c) If the fair  market  value  cannot be  determined  under the  preceding
methods, it shall be determined in good faith by the Board.

Section 7.        Option Manner of Payment; Option Manner of Exercise.
                  ---------------------------------------------------

     (a)  Options  granted  under the Plan may  provide  for the  payment of the
exercise price by delivery of:

          (i) cash or a check  payable to the order of the  Company in an amount
     equal to the exercise price of such Options,

          (ii)  shares  of Common  Stock of the  Company  owned by the  optionee
     having a fair  market  value equal in amount to the  exercise  price of the
     Options being exercised,

          (iii) any combination of (i) and (ii), provided, however, that payment
     of the exercise  price by delivery of shares of Common Stock of the Company
     owned by such  optionee  may be made only under such  circumstances  and on
     such terms as may from time to time be established by the Board and only if
     provided for in the Option  Agreement.  The fair market value of any shares
     of the  Company's  Common Stock which may be delivered  upon exercise of an
     Option  shall be  determined  by the  Board in  accordance  with  Section 6
     hereof.  Payment  may  also be  made by  delivery  of a  properly  executed
     exercise  notice  to the  Company,  together  with a  copy  of  irrevocable
     instructions  to a broker to deliver  promptly to the Company the amount of
     sale or loan  proceeds to pay the  exercise  price if  provided  for in the
     Agreement.  To  facilitate  the  foregoing,  the  Company  may  enter  into
     agreements for coordinated procedures with one or more brokerage firms,

          (iv) in consideration  received by the Company under a formal cashless
     exercise program  maintained with an outside broker adopted by the Board in
     connection with the Plan, or

          (v) by any other means approved by the Board.

     (b) To the extent  that the right to  purchase  shares  under an Option has
accrued  and is in effect,  Options may be  exercised  in full at one time or in
part  from time to time,  by  giving  written  notice,  signed by the  person or
persons exercising the Option, to the Company, stating the number of shares with
respect to which the Option is being  exercised,  accompanied by payment in full
for such shares as  provided  in  subparagraph  (a) above.  Upon such  exercise,
delivery of a certificate for paid-up non-assessable shares shall be made at the
principal  office of the Company to the person or persons  exercising the Option
at such time, during ordinary  business hours,  after ten business days from the
date of receipt of the notice by the  Company,  as shall be  designated  in such
notice,  or at such time,  place and manner as may be agreed upon by the Company
and the person or persons exercising the Option.

Section 8.        Exercise of Options.
                  -------------------

     Subject to the  provisions  of  Sections 9 through 11 and 13,  each  Option
granted under the Plan shall be exercisable as follows:

     (a) Vesting.  The Option shall either be fully  exercisable  on the date of
         -------
grant or shall become  exercisable  thereafter in such installments as the Board
may specify;

                                       63
<PAGE>

     (b) Full Vesting of Installments.  Once an installment  becomes exercisable
         ----------------------------
it shall remain  exercisable  until  expiration of the Option,  unless otherwise
specified by the Board;

     (c) Partial  Exercise.  Each Option or installment  may be exercised at any
         -----------------
time or from time to time,  in whole or in part,  for up to the total  number of
shares with respect to which it is then exercisable; and

     (d)  Acceleration of Vesting.  The Board shall have the right to accelerate
          -----------------------
the date of exercise of any  installment of any Option;  provided that the Board
shall not,  without the consent of an optionee,  accelerate the exercise date of
any  installment  of any  Option  granted  to  any  employee  as an ISO if  such
acceleration  would violate the annual vesting  limitation  contained in Section
422(d) of the Code. The Board, in its sole  discretion,  shall have the right to
provide in any  Agreement  for the  acceleration  of the date of exercise of any
installment of any Option granted  hereunder upon the occurrence of any event or
circumstance as the Board shall determine.

Section 9.        Term of Options' Exercisability.
                  -------------------------------

     (a) Term.  Each Option  shall  expire not more than ten (10) years from the
         ----
date of the granting thereof but shall be subject to earlier  termination as may
be provided in any Agreement evidencing an Option granted hereunder.

     (b)  Exercisability.  Subject to the  provisions  of  Section 10 below,  an
          --------------
Option  granted to an  employee  optionee  who ceases to be an  employee  of the
Company or one of its subsidiaries  shall be exercisable only to the extent that
the right to purchase  shares  under such Option has accrued and is in effect on
the date such  optionee  ceases to be an  employee  of the Company or one of its
subsidiaries.

Section 10.       Employee's Post-Termination Exercise of Options
                  -----------------------------------------------

     (a) An Option will, to the extent not  previously  exercised by an employee
optionee,  terminate  three  (3)  months  after  the  date on  which  optionee's
employment  by  the  Company  or  an  Affiliate  is  terminated   (whether  such
termination be voluntary or involuntary)  other than by reason of disability (as
defined in Section 22(e)(3) of the Code, and the Regulations thereunder),  Cause
(as defined  below) or death.  In the event of  termination of employment due to
disability  or death,  the Option will  terminate  one (1) year from the date of
termination  of  employment  due  to  disability  or  death.  In  the  event  of
termination  of employment due to Cause,  the Option will terminate  immediately
and automatically upon such termination. After the date optionee's employment is
terminated, as aforesaid,  optionee may exercise this Option only for the number
of shares  which  optionee  had a right to purchase  and did not purchase on the
date optionee's employment terminated.  If optionee is employed by an Affiliate,
optionee's  employment shall be deemed to have terminated on the date optionee's
employer  ceases to be an Affiliate of the Company,  unless  optionee is on that
date  transferred  to the Company or another  Affiliate.  Optionee's  employment
shall not be deemed to have  terminated  if  optionee  is  transferred  from the
Company  to an  Affiliate,  or vice  versa,  or from one  Affiliate  to  another
Affiliate.  "Cause" means, in the absence of an employment,  consulting or other
agreement otherwise defining Cause and applicable to a particular optionee:  (i)
incompetence,  fraud,  personal  dishonesty,   embezzlement  or  acts  of  gross
negligence  or gross  misconduct on the part of optionee in the course of his or
her  employment or services,  (ii) an  optionee's  engagement in conduct that is
materially  injurious  to the  Company  or an  Affiliate,  (iii)  an  optionee's
conviction by a court of competent  jurisdiction of, or pleading "guilty" or "no

                                       64
<PAGE>

contest" to, (x) a felony,  or (y) any other  criminal  charge (other than minor
traffic  violations)  which  could  reasonably  be  expected  to have a material
adverse  impact on the Company's or an  Affiliate's  reputation or business;  or
(iv)  willful  failure  by an  optionee  to follow the  lawful  directions  of a
superior officer or the Board.

     (b) If  optionee  dies  while  employed  by the  Company  or an  Affiliate,
optionee's  executor  or  administrator,  as the case may be,  may,  at any time
within one (1) year after the date of optionee's  death,  exercise the Option as
to any shares which optionee had a right to purchase and did not purchase during
optionee's lifetime.  If optionee's  employment with the Company or an Affiliate
is terminated by reason of optionee's  becoming  disabled (within the meaning of
Section  22(e)(3)  of the  Code and the  Regulations  thereunder),  optionee  or
optionee's legal guardian or custodian may at any time within one (1) year after
the  date of such  termination,  exercise  the  Option  as to any  shares  which
optionee had a right to purchase and did not purchase prior to such termination.
Optionee's executor, administrator,  guardian or custodian must present proof of
his or her  authority  satisfactory  to the  Company  prior to being  allowed to
exercise this Option.

Section 11.       Transferability of Options.
                  --------------------------

     (a) An Option  shall not be  transferable  except by will or by the laws of
descent and  distribution  and shall be  exercisable  during the lifetime of the
optionee only by the optionee.  Notwithstanding the foregoing, the optionee may,
by  delivering  written  notice to the Company,  in a form  satisfactory  to the
Company, designate a third party who, in the event of the death of the optionee,
shall thereafter be entitled to exercise the Option.

     (b)  Notwithstanding  the foregoing,  a Nonqualified  Stock Option shall be
transferable to the extent provided in the Option Agreement.

Section 12.       Provisions Of Stock Grants.
                  --------------------------
     (a) Stock Bonus Grants. Each stock bonus grant shall be evidence by a stock
         ------------------
bonus agreement ("Stock Bonus Agreement") duly executed on behalf of the Company
and by the grantee, which Stock Bonus Agreement shall comply with and be subject
to the terms and conditions of the Plan. The Stock Bonus  Agreement  shall be in
such form and shall  contain such terms and  conditions  as the Board shall deem
appropriate.  The terms and conditions of Stock Bonus Agreements may change from
time to time, and the terms and  conditions of separate  Stock Bonus  Agreements
need not be identical,  but each Stock Bonus  Agreement  shall include  (through
incorporation  of provisions  hereof by reference in the agreement or otherwise)
the substance of each of the following provisions:

          (i)  Consideration.  A stock bonus may be awarded in consideration for
               -------------
     past  services  actually  rendered to the Company or an  Affiliate  for its
     benefit.

          (ii)  Vesting.  Shares of Common Stock  awarded  under the Stock Bonus
                -------
     Agreement  may,  but need not, be subject to a share  repurchase  option in
     favor of the Company in accordance with a vesting schedule to be determined
     by the Board.

          (iii) Termination of Stock Bonus Holder's  Employment.  In the event a
                -----------------------------------------------
     stock  bonus  grantee's  employment  or  other  service  with  the  Company
     terminates,  the Company may  reacquire  any or all of the shares of Common
     Stock held by the stock bonus  grantee which have not vested as of the date
     of termination under the terms of the Stock Bonus Agreement.

                                       65

     the Stock Bonus  Agreement shall be transferable by the stock bonus grantee
     only upon such  terms and  conditions  as are set forth in the Stock  Bonus
     Agreement,  as the Board  shall  determine  in its  discretion,  so long as
     Common Stock awarded under the Stock Bonus Agreement remains subject to the
     terms of the Stock Bonus Agreement.

     (b) Restricted Stock Purchase Grants.  Each restricted stock purchase grant
         --------------------------------
shall be evidence by a restricted stock purchase  agreement  ("Restricted  Stock
Purchase  Agreement") duly executed on behalf of the Company and by the grantee,
which  Restricted  Stock Purchase  Agreement shall comply with and be subject to
the terms and conditions of the Plan. The  Restricted  Stock Purchase  Agreement
shall be in such form and shall  contain such terms and  conditions as the Board
shall  deem  appropriate.  The  terms and  conditions  of the  Restricted  Stock
Purchase  Agreements  may change from time to time, and the terms and conditions
of separate Restricted Stock Purchase Agreements need not be identical, but each
Restricted  Stock Purchase  Agreement shall include  (through  incorporation  of
provisions  hereof by reference in the agreement or otherwise)  the substance of
each of the following provisions:

          (i)  Purchase  Price.  Subject  to  the  provisions  of  Section  4(c)
               ---------------
     regarding 10% shareholders,  the purchase price under each Restricted Stock
     Purchase  Agreement  shall be such amount as the Board shall  determine and
     designate in such Restricted Stock Purchase  Agreement.  In no event, shall
     the  purchase  price shall be less than  eighty-five  percent  (85%) of the
     Common  Stock's  fair market value on the date such grant is made or at the
     time the purchase is consummated.

          (ii)  Consideration.  The  purchase  price of  Common  Stock  acquired
                -------------
     pursuant to the Restricted  Stock Purchase  Agreement shall be paid either:
     (A) in cash at the time of purchase;  (B) at the  discretion  of the Board,
     according  to a deferred  payment  or other  similar  arrangement  with the
     restricted  stock  purchase  grantee;  or (C) in any  other  form of  legal
     consideration that may be acceptable to the Board in its discretion.

          (iii)  Vesting.  Shares of Common Stock  acquired under the Restricted
                 -------
     Stock  Purchase  Agreement  may,  but  need  not,  be  subject  to a  share
     repurchase  option in favor of the  Company  in  accordance  with a vesting
     schedule to be determined by the Board.

          (iv) Termination of Restricted Stock Purchase  Grantee's  Service.  In
               ------------------------------------------------------------

     with the  Company  terminates,  the  Company may  repurchase  or  otherwise
     reacquire  any or all of the shares of Common Stock held by the  restricted
     stock purchase  grantee which have not vested as of the date of termination
     under the terms of the Restricted Stock Purchase Agreement.

          (v)  Transferability.  Rights to acquire  shares of Common Stock under
               ---------------
     the  Restricted  Stock  Purchase  Agreement  shall be  transferable  by the
     restricted  stock  purchase  grantee only upon such terms and conditions as
     are set forth in the  Restricted  Stock  Purchase  Agreement,  as the Board
     shall  determine in its  discretion,  so long as Common Stock awarded under
     the Restricted Stock Purchase Agreement remains subject to the terms of the
     Restricted Stock Purchase Agreement.

Section 13.       Adjustments.
                  -----------

     (a) Upon the occurrence of any of the following  events,  an Award holder's

          (i) Common Stock  Dividends and Common Stock Splits.  If the shares of
              -----------------------------------------------
     Common  Stock shall be  subdivided  or  combined  into a greater or smaller
     number of shares or if the Company  shall issue any shares of Common  Stock
     as a stock dividend on its outstanding  Common Stock,  the number of shares
     of  Common  Stock  deliverable  upon  the  exercise  of  Options  shall  be
     appropriately  increased  or  decreased  proportionately,  and  appropriate
     adjustments  shall be made in the purchase  price per share to reflect such
     subdivision, combination or stock dividend; and

          (ii)   Recapitalization   or   Reorganization.   In  the  event  of  a
                 ----------------
     recapitalization  or  reorganization  of the Company  (except as  otherwise
     provided  in any Option  Agreement)  pursuant  to which  securities  of the
     Company  or  of  another   corporation  are  issued  with  respect  to  the
     outstanding  shares of Common Stock,  an optionee upon exercising an Option
     shall be entitled to receive for the purchase price paid upon such exercise
     the  securities  the  optionee  would have  received  if the  optionee  had
     exercised the Option prior to such recapitalization or reorganization.

          (iii)  Modification  of  ISOs.   Notwithstanding  the  foregoing,  any
                 ----------------------
     adjustments made pursuant to subparagraphs (i) or (ii) with respect to ISOs
     shall be made only after the Board,  after  consulting with counsel for the
     Company,   determines   whether  such   adjustments   would   constitute  a
     "modification"  of such ISOs (as that term is defined in Section 424 of the
     Code) or would cause any adverse tax  consequences  for the holders of such
     ISOs. If the Board  determines that such  adjustments  made with respect to
     ISOs would  constitute  a  modification  of such ISOs,  it may refrain from
     making such adjustments.

          (iv)  Dissolution  or  Liquidation.  In  the  event  of  the  proposed
                ----------------------------
     dissolution  or  liquidation  of the  Company,  each Option will  terminate
     immediately  prior to the  consummation  of such proposed action or at such
     other time and subject to such other  conditions  as shall be determined by
     the Board.

          (v) Issuances of Securities.  Except as expressly  provided herein, no
              -----------------------
     issuance  by the  Company  of shares of stock of any class,  or  securities
     convertible  into  shares  of  stock of any  class,  shall  affect,  and no
     adjustment  by reason  thereof shall be made with respect to, the number or
     price of  shares  subject  to  Options.  No  adjustments  shall be made for
     dividends paid in cash or in property other than securities of the Company.

          (vi) Fractional  Shares. No fractional share shall be issued under the
               ------------------
     Plan and the optionee  shall  receive from the Company cash in lieu of such
     fractional shares.

          (vii)  Adjustments.  Upon the happening of any of the events described
                 -----------
     in  subparagraphs  (i) or (ii)  above,  the class and  aggregate  number of
     shares  set forth in  Section 2 and  Section 4 hereof  that are  subject to
     Options which previously have been or subsequently may be granted under the
     Plan shall also be  appropriately  adjusted to reflect the events described
     in such  subparagraphs.  The Board or Successor  Board shall  determine the
     specific  adjustments  to be made  under this  Section  13 and,  subject to
     Section 3, its determination shall be conclusive.

     (b) If any person or entity  owning  restricted  Common  Stock  obtained by
exercise of an Option made  hereunder  receives  shares or securities or cash in
connection with a corporate  transaction  described in subparagraphs (i) or (ii)
above as a result  of  owning  such  restricted  Common  Stock,  such  shares or
securities or cash shall be subject to all of the  conditions  and  restrictions
applicable to the  restricted  Common Stock with respect to which such shares or
securities or cash were issued,  unless otherwise determined by the Board or the
Successor Board.

Section 14.       No Special Employment Rights.
                  ----------------------------

     Nothing  contained in the Plan or in any Award granted under the Plan shall
confer upon any Award holder any right with respect to the  continuation  of his
employment by the Company or an Affiliate or interfere in any way with the right
of the Company or an Affiliate,  subject to the terms of any separate employment
agreement  to the  contrary,  at any time to  terminate  such  employment  or to
increase  or  decrease  the  compensation  of the Award  holder from the rate in
existence at the time of the grant of an Award.  Whether an authorized  leave of
absence,  or  absence  in  military  or  government  service,  shall  constitute
termination of employment shall be determined by the Board at the time.

Section 15.       Withholding Tax.
                  ---------------

     The Company's  obligation to deliver  shares upon the exercise of any Award
granted under the Plan shall be subject to the Award  holder's  satisfaction  of
all applicable Federal, state and local income, excise, employment and any other
tax  withholding  requirements.  The Company and  employee may agree to withhold
shares of Common  Stock  purchased  upon  exercise  of an Award to  satisfy  the
above-mentioned withholding requirements. The Board shall also have the right to
require that shares be withheld from delivery to satisfy such condition.

Section 16.       Restrictions on Issue of Shares.
                  -------------------------------

     (a)  Notwithstanding the provisions of Section 7, the Company may delay the
issuance of shares  covered by an Award and the  delivery of a  certificate  for
such shares until one of the following conditions shall be satisfied:

          (i) The shares with  respect to which such Award has been  granted are
     at the time of the issue of such shares effectively registered or qualified
     under  applicable  Federal  and  state  securities  acts now in force or as
     hereafter amended; or

          (ii)  Counsel  for the  Company  shall  have given an  opinion,  which
     opinion shall not be unreasonably conditioned or withheld, that such shares
     are exempt from registration  under applicable Federal and state securities
     acts now in force or as hereafter amended.

     (b) It is  intended  that all Awards  shall be  effective,  and the Company
shall use its best efforts to bring about  compliance with the above  conditions
within a reasonable  time,  except that the Company shall be under no obligation
to  qualify  shares or to cause a  registration  statement  or a  post-effective
amendment  to any  registration  statement  to be  prepared  for the  purpose of
covering  the  issue of  shares in  respect  of which any Award may be  granted,
except as otherwise agreed to by the Company in writing.

Section  17.   Purchase  For   Investment;   Rights  of  Holder  on   Subsequent
               -----------------------------------------------------------------
               Registration.
               ------------

     (a)  Unless the shares to be issued in  connection  with any Award  granted
under the Plan have been effectively  registered or are exempt from registration
under the  Securities  Act of 1933,  as now in force or hereafter  amended,  the
Company shall be under no  obligation  to issue any shares  covered by any Award
unless the Award holder shall give a written  representation  and undertaking to
the Company which is  satisfactory  in form and scope to counsel for the Company

                                       68
<PAGE>

and upon which, in the opinion of such counsel, the Company may reasonably rely,
that he or she is acquiring the shares issued  pursuant to such Award for his or
her  own  account  as an  investment  and not  with a view  to,  or for  sale in
connection  with, the  distribution of any such shares,  and that he or she will
make no transfer of the same except in compliance with any rules and regulations
in force at the time of such transfer  under the  Securities Act of 1933, or any
other applicable law, and that if shares are issued without such registration, a
legend to this effect may be endorsed upon the securities so issued.

     (b) In the event that the Company shall, nevertheless, deem it necessary or
desirable  to  register  under the  Securities  Act of 1933 or other  applicable
statutes any shares with respect to which an Award shall have been  granted,  or
to qualify  any such shares for  exemption  from the  Securities  Act of 1933 or
other applicable statutes, then the Company may take such action and may require
from each  optionee  such  information  in writing  for use in any  registration
statement,   supplementary  registration  statement,   prospectus,  or  offering
circular as is reasonably  necessary for such purpose and may require reasonable
indemnity to the Company and its officers and directors and controlling  persons
from such holder against all losses,  claims,  damages and  liabilities  arising
from such use of the information so furnished and caused by any untrue statement
of any material  fact therein or caused by the omission to state a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading in the light of the circumstances under which they were made.

Section 18.       Loans.
                  -----

     The Company may make loans to optionees to permit them to exercise Options.
If loans are made, the requirements of all applicable Federal and state laws and
regulations regarding such loans must be met.

Section 19.       Modification of Outstanding Awards.
                  ----------------------------------

     The Board may  authorize the  amendment of any  outstanding  Award with the
consent of the optionee when and subject to such  conditions as are deemed to be
in the best interests of the Company and in accordance with the purposes of this
Plan.

Section 20.       Approval of Stockholders.
                  ------------------------

     The Plan shall be subject to approval by the vote of  stockholders  holding
at least a majority of the voting stock of the Company present,  or represented,
and entitled to vote at a duly held stockholders' meeting, or by written consent
of stockholders  holding at least a majority of the voting stock of the Company,
within  twelve (12) months after the adoption of the Plan by the Board and shall
take  effect as of the date of  adoption  by the Board upon such  approval.  The
Board may grant Awards under the Plan prior to such approval, but any such Award
shall  become  effective  as of the date of grant only upon such  approval  and,
accordingly, no such Option may be exercisable prior to such approval.

Section 21.       Termination and Amendment.
                  -------------------------

     (a) Unless sooner  terminated as herein provided,  the Plan shall terminate
ten (10) years  from the date upon which the Plan was duly  adopted by the Board
of the  Company.  The  Board  may at any time  terminate  the Plan or make  such
modification or amendment thereof as it deems advisable; provided, however, that
except as provided in this  Section 21, the Board may not,  without the approval
of the  stockholders of the Company obtained in the manner stated in Section 20,

                                       69
<PAGE>

increase the maximum  number of shares for which Awards may be granted or change
the  designation  of the class of persons  eligible to receive  Awards under the
Plan, or make any other change in the Plan which requires  stockholder  approval
under  applicable law or regulations or any applicable rule or regulation of any
stock exchange or over-the-counter market on which the Company's Common Stock is
then listed.  The Board may grant Awards under the Plan prior to such  approval,
but any such Award shall become effective as of the date of grant only upon such
approval  and,  accordingly,  no such  Award  may be  exercisable  prior to such
approval.

     (b) The Board may terminate,  amend or modify any outstanding Award without
the consent of the Award holder, provided,  however, that, except as provided in
Section 13, without the consent of the optionee,  the Board shall not change the
number of shares subject to an Award, nor the exercise price thereof, nor extend
the term of such Award.

Section 22.       Reservation of Common Stock.
                  ---------------------------

     The Company shall at all times during the term of the Plan reserve and keep
available  such number of shares of stock as will be  sufficient  to satisfy the
requirements  of the  Plan and  shall  pay all  fees  and  expenses  necessarily
incurred by the Company in connection therewith.

Section 23.       Limitation of Rights in the Award Shares.
                  ----------------------------------------

     An optionee  shall not be deemed for any purpose to be a stockholder of the
Company  with  respect to any of the Awards  except to the extent that the Award
shall have been exercised with respect  thereto and, in addition,  a certificate
shall have been issued theretofore and delivered to the optionee.

sufficiency  of which are hereby  acknowledged,  the Employer and the  Executive
agree as follows:

         SECTION 1.        Employment Relationship.

     hereby  agrees to be  employed  by the  Employer,  as  President  and Chief
     Executive Officer of Employer.  During the Executive's  employment with the
     Employer,  the Executive shall report directly to the Board of Directors of
     the Employer (the  "Board").  The  Executive  agrees to abide by the rules,
     regulations, instructions, personnel practices and policies of the Employer
     and any  changes  therein  which  may be  adopted  from time to time by the
     Employer.  The Executive  acknowledges  receipt of copies of all such rules
     and policies committed to writing as of the date of this Agreement.

          (ii)  The  Executive  shall  do and  perform  all  services  and  acts
     necessary or advisable  to fulfill the duties and  responsibilities  as are
     commensurate  and consistent with the  Executive's  position and such other
     services  as  reasonably  requested  by the  Board  (the  "Services").  The
     Executive agrees to devote all of the Executive's  working time,  attention
     and efforts to the  Employer  and to perform the duties of the  Executive's
     position in accordance with the Employer's  policies as in effect from time
     to time;  provided that, the Executive shall be permitted to engage in such
     limited  and  non-competitive  outside  business  activities  that  do  not
     interfere  with the  performance  of his  duties  hereunder  only as may be
     approved  by the Board in  advance  in  accordance  with the  business  and
     ethical standards of the Company adopted from time to time. The Executive's
     principal  place of employment  shall be the Employer's  offices located in
     the Glenn Dale, Maryland area.

     (b) Employment Period.
         -----------------

          (i) Subject to earlier  termination  as set forth  herein,  the period
     commencing  on January  1, 2003,  and  ending on  December  31,  2005 (such
     three-year term being referred to as the "Initial  Term").  Notwithstanding
     anything  to  the  contrary  contained  in  the  preceding  sentence,  this
     Agreement  shall be  automatically  renewed for  successive  one-year terms
     (each such one-year  term a "Renewal  Term"),  unless sooner  terminated in
     accordance with the provisions  hereof, or unless either party gives to the
     other party  written  notice of intent not to renew the  Agreement at least
     ninety (90) days prior to the end of the Initial Term or any Renewal  Term.
     For the purposes of this Agreement,  the Initial Term and each Renewal Term
     shall collectively be referred to as the "Employment Period."

          (ii)  Executive  agrees  and  acknowledges  that the  Employer  has no
     obligation  to  extend  the  Employment  Period,  and  Executive  expressly
     acknowledges  that no promises or  understandings to the contrary have been
     made or reached.  Executive also agrees and acknowledges  that,  should the
     Employer choose to continue  Executive's  employment for any period of time
     after the expiration of the Employment Period,  Executive's employment with
     the Employer, unless otherwise agreed by the parties, will be "at will." In

                                       72
<PAGE>

     other words,  during any time  following the  expiration of the  Employment
     Period,  unless otherwise agreed by the parties, the Employer may terminate
     Executive's  employment  at any time,  with or  without  reason and with or
     without  notice,  and  Executive  may  resign at any time,  with or without
     reason and with or without  notice.  All  references  herein to the term of
     this  Agreement  shall refer to the Initial Term,  the Renewal Term and any
     successive term as the context logically requires.

                           -----------

     (a) Death or  Disability.  If the  Executive  dies  during  the  Employment
         --------------------
Period,  the Employment Period shall terminate as of the date of the Executive's
death.  Similarly,  the Employment  Period shall terminate as of the date of the
Executive's  Disability.  For purposes of this Agreement,  the term "Disability"
shall mean:  (i) when  Executive is determined to be totally  disabled under the
terms of any disability  income insurance policy  maintained by the Employer for
the  benefit of  Executive;  (ii)  Executive's  inability,  because of mental or
physical impairment,  to perform his duties under this Agreement for a period in
excess of ninety (90) consecutive days, or (iii) Executive's inability,  because
of mental or physical impairment, to perform his duties under this Agreement for
a period in excess of one hundred  eighty (180) days in any  consecutive  twelve
(12) month  period,  if, in the case of either (ii) or (iii),  a duly  licensed,
actively practicing physician reasonably acceptable to the Employer certifies in
a written medical opinion and with reasonable  medical  certainty that Executive
is and will  continue to be unable to perform his regular  full-time  employment

duties with the Employer  for a period of six (6) months after the  commencement
date of such  disability.  During any period  prior to such  termination  during
which the Executive is absent from the full-time  performance of the Executive's
duties with the Employer due to  Disability,  the Employer shall continue to pay
the  Executive's  Base Salary at the rate in effect at the  commencement of such
period of Disability,  offset by any amounts  payable to the Executive under any
disability insurance plan or policy provided by the Employer.

     (b) Cause. The Employer, at its option, may terminate the Employment Period
         -----
and all of the  obligations  of the Employer  under this  Agreement for Cause at
anytime. The Employer shall have "Cause" to terminate the Executive's employment
hereunder in the event of: (i) the Executive's  conviction of, plea of guilty or

Agreement,  (iii)  the  Executive's  failure  to  perform  his  duties  ably and
competently;  (iv) the Executive's  willful misconduct in the performance of the
Services,  or (v) Executive's  breach of the provisions of Section 4 and/or 5 of
this Agreement;  provided that, in the case of an event described in clause (ii)

at a meeting of the Board,  and (B) the  Executive  has not cured such action to
the  satisfaction  of the Board within  thirty (30) days after  meeting with the
Board.

     (c)  Termination by Executive for Good Reason.  The Executive may terminate
          ----------------------------------------
this  Agreement  upon thirty (30) days prior written notice to the Employer that
Good Reason (as defined below) has occurred,  with such notice setting forth the
basis  therefor,  if the  basis for such Good  Reason is not cured  within  such
30-day period after written notice.  "Good Reason" means: (i) the failure of the
Employer  to pay any  amounts  due under  this  Agreement,  other  than  amounts
disputed in good faith with the basis for such dispute set forth by the Employer
in  writing,  (ii) a  substantial  diminution  in the  material  status,  title,
position or responsibilities  of the Executive,  other than for Cause, (iii) the
requirement  that the Executive engage in any unlawful act or act of dishonesty,
fraud  or  deception  in the  course  of his  employment,  or  (iv)  Executive's

     or his  estate  any  accrued  and unpaid  compensation  (together  with any
     interest or earnings thereon) that has not yet been paid; provided that, in
     the event of termination of the Employment Period due to Executive's death,
     Employer shall pay to Executive's  surviving heirs a lump sum payment equal
     to three (3) months of the then-current  Base Salary within sixty (60) days
     of the date of death, in addition to any other  death-related  benefits the
     Employer may provide.

          (ii)  Standard  Involuntary  Termination  Payment.  Subject to Section
                -------------------------------------------

     time either by the  Employer  without  Cause or by the  Executive  for Good
     Reason,  the Employer shall continue to provide to the Executive  both: (A)

     Notwithstanding  the  foregoing,  in the  event of the  termination  of the
     Employment  Period  within the one (1) year  period  following  a Change of
     Control (as hereinafter defined) either by the Employer without Cause or by
     the Executive for Good Reason,  the Employer  shall  continue to provide to
     the Executive both: (A) the Executive's Base Salary and (B) continuation of
     all  benefits  otherwise  to be  provided  under  Section  2(c)  hereof had
     employment  not  terminated  for a period  equal to the greater of: (1) the
     Employment  Period  then  remaining,  or (2) a twelve  (12)  month  period.
     Additionally,  in such an event,  Executive shall be entitled to receive an
     Annual  Bonus  for  the  year  during  which  such   termination   occurred
     notwithstanding  that  Executive  is not  employed by Employer on the Bonus
     Payment  Date.  In such an event,  the Annual  Bonus shall be pro rated and
     calculated  based upon the  number of full  months  actually  worked by the
     Executive.

          (iv) "Change of Control"  Defined.  For purposes of this Agreement,  a
     "Change of Control" means: (a) the sale of all or substantially  all of the
     assets of the Employer, (b) the dissolution or liquidation of the Employer,
     or (c) any merger, share exchange, consolidation or other reorganization or
     business  combination of the Employer if immediately after such transaction
     either: (1) persons who were directors of the Employer immediately prior to
     such  transaction do not constitute at least a majority of the directors of
     the surviving  entity,  or (2) persons who hold over fifty percent (50%) of
     the voting  capital stock of the surviving  entity are not persons who held
     voting capital stock of the Employer immediately prior to such transaction.

         SECTION 4.        Confidentiality; Non-Disclosure.
                           -------------------------------

     (a) Confidentiality.
         ---------------

          (i) Non-Disclosure  Obligation.  The Executive acknowledges that while
              --------------------------
     employed by the Employer, the Executive will occupy a position of trust and
     confidence.  The  Executive  shall not  disclose to others or use,  whether
     directly or indirectly, any Confidential Information regarding the Employer
     or any of its subsidiaries;  provided.  However,  that this Section 4(a)(i)
     shall not apply to any disclosure:  (A) required to perform the Executive's
     duties  hereunder;  (B) required by applicable  law; or (C) of  information
     that shall have  become  public  other than by the  Executive's  authorized
     disclosure. "Confidential Information" means all "Developments" (as defined
     below) and all information  about the Employer or any of its  subsidiaries,
     and their  clients and  customers  that is not disclosed by the Employer or
     any of its  subsidiaries  in the  ordinary  course of business and that was
     learned by the  Executive in the course of employment by the Employer or by
     the  Executive  in the  course of  employment  by any of its  subsidiaries,
     including (without  limitation) any proprietary  knowledge,  trade secrets,
     data, formulae, information and client and customer lists, prospects lists,
     pricing   information,   quotations,   budgets,   proposals,   existing  or
     contemplated  services or  products,  research,  financial,  marketing  and
     operational plans,  proposals and strategies and all papers,  resumes,  and
     records  (including  computer  records) of the  documents  containing  such
     Confidential Information. The Executive acknowledges that such Confidential
     Information  is  specialized,  unique in nature  and of great  value to the
     Employer and its subsidiaries, and that such information gives the Employer
     and its  subsidiaries  a competitive  advantage.  The  Executive  agrees to
     deliver or return to the Employer, at the Employer's request at any time or
     upon  termination  or expiration of the  Executive's  employment or as soon
     thereafter as possible,  all documents,  computer tapes and disks, records,
     lists,  data,  drawings,  prints,  notes and written  information  (and all
     copies thereof)  furnished by the Employer and its subsidiaries or prepared
     by  the  Executive  in the  course  of the  Executive's  employment  by the
     Employer and its  subsidiaries.  As used in this Agreement,  "subsidiaries"
     means any company controlled by the Employer.

          (ii) Compulsory Disclosures.  If the Executive is requested or (in the
               ----------------------
     opinion of his counsel)  required by law or judicial  order to disclose any
     Confidential  Information,  the  Executive  shall provide the Employer with
     prompt notice of any such request or  requirement  so that the Employer may
     seek  an  appropriate   protective  order  or  waiver  of  the  Executive's
     compliance with the provisions of this Section 4(a).

     (b)   Intellectual   Property.   Executive  agrees  that  all  innovations,
           -----------------------
inventions,  discoveries,  developments,  improvements,  works of authorship and
computer programs and related documentation that are made, conceived of or first
reduced to practice  by  him/her,  either  solely or jointly  with others  while
employed by the  Employer  as a result of tasks  assigned  to  Executive  by the
Employer,  or from the use of premises or property  owned,  leased or contracted
for  by the  Employer  (collectively,  the  "Developments"),  and  any  and  all
intellectual  property and other proprietary rights relating thereto whatsoever,
whether  patented,  copyrighted,  maintained  as  a  trade  secret,  registered,
recorded or otherwise  protected  (collectively,  the "Intellectual  Property"),
will be the  sole  and  exclusive  property  of the  Employer.  Executive  shall
promptly disclose to the Employer all Developments,  and Executive shall have no

                                       76
<PAGE>

claim for additional compensation for the Developments or Intellectual Property.
Executive shall execute such  instruments as may be requested by the Employer to
confirm the Employer's  ownership of all Intellectual  Property  described,  and
shall,  at the  Employer's  expense,  provide all  reasonable  assistance in the
application, preparation, filing, prosecution and maintenance of any protections
relating to such  property,  or such other actions as may be required to perfect
the Employer's interest in such property.

         SECTION 5.        Non-Competition; Non-Solicitation.
                           ---------------------------------

     (a) Executive  acknowledges  and recognizes his possession of  Confidential
Information and  acknowledges the highly  competitive  nature of the business of
the  Employer and  accordingly  agrees that,  in  consideration  of the premises
contained herein, he will not, during the Employment Period and for one (1) year
after  the  date  of  termination  of his  employment  for  any  reason,  either
individually or as an officer, director, stockholder, member, employee, partner,
agent, consultant or principal of another business firm (other than as a passive
shareholder  of a company  in which the  Executive  owns less than five  percent
(5%)):  (i) engage in any business  which  competes  directly with Employer with
respect to the Employer's services and products, (ii) solicit to perform for any
Customer  or  Prospective  Customer,  or  (iii)  perform  for  any  Customer  or
Prospective  Customer,  for the purpose of  providing  services or products of a
nature or kind  similar to those  provided  by the  Employer,  or proposed to be
provided by the Employer,  to any Customer or Prospective  Customer.  "Customer"
means any entity that has  purchased  products or services  from the Employer at
any  time  within  two  (2)  years  prior  to  the  termination  of  Executive's
employment, and "Prospective Customer" means any entity either identified by the
Employer  for  solicitation  for  products  or  services,  or  solicited  by the
Employer, any time within one (1) year prior to the Executive's termination.

     (b) The Executive recognizes that he will possess confidential  information
about other  employees of the Employer  and its  subsidiaries  relating to their
education,  experience,  skills,  abilities,   compensation  and  benefits,  and
inter-personal relationships with suppliers to and customers of the Employer and
its subsidiaries.  The Executive recognizes that the information he will possess
about these other employees is not generally  known, is of substantial  value to
the Employer and its subsidiaries in developing their respective  businesses and
in securing and retaining  customers,  and will be acquired by Executive because
of Executive's business position with the Employer. Executive agrees that during
the  Employment  Period or for one (1) year after the date of termination of his
employment,  Executive will not, directly or indirectly,  hire, recruit, solicit
or induce,  or attempt to hire,  recruit solicit or induce,  any employee of the
Employer for the purpose of being employed or otherwise  engaged by Executive or
by any business,  individual,  partnership, firm, corporation or other entity on
whose behalf Executive is acting as an employee,  agent or other  representative
and that Executive will not convey any Confidential Information or trade secrets
about other  employees of the Employer or any of its  subsidiaries  to any other
person except within the scope of Executive's duties hereunder.

         SECTION 6.        General Provisions.
                           ------------------

     (a) Enforceability.  It is the desire and intent of the parties hereto that
         --------------
the  provisions  of this  Agreement  shall be  enforced  to the  fullest  extent
permissible  under the laws and public policies applied in each  jurisdiction in
which  enforcement  is  sought.  Accordingly,  although  the  Executive  and the
Employer consider the restrictions  contained in this Agreement to be reasonable
for the express  purpose of preserving the Employer's  goodwill and  proprietary
rights, if any particular provision of this Agreement shall be adjudicated to be
invalid  or  unenforceable,  such  provision  shall be deemed  amended to delete
therefrom  the portion thus  adjudicated  to be invalid or  unenforceable,  such
deletion to apply only with respect to the  operation  of such  provision in the
particular  jurisdiction  in which such  adjudication  is made.  It is expressly
understood and agreed that although the Employer and the Executive  consider the
restrictions  contained in Section 5 to be  reasonable  and necessary to protect
the Employer's  legitimate business interests,  if a final determination is made
by a court of  competent  jurisdiction  that the time or  territory or any other
restriction  contained in this Agreement is unenforceable against the Executive,
the  provisions of this  Agreement  shall be deemed  amended to apply as to such
maximum  time  and  territory  and to such  maximum  extent  as such  court  may
judicially determine or indicate to be enforceable.

     (b) Remedies; Survival. The parties acknowledge that the Employer's damages
         ------------------
at law may be an  inadequate  remedy  for the  breach  by the  Executive  of any
provision  of Section 4 or Section 5, and agree in the event of such breach that
the Employer may obtain temporary and permanent  injunctive  relief  restraining
the  Executive  from such  breach,  and,  to the  extent  permissible  under the
applicable  statutes  and rules of  procedure,  a  temporary  injunction  may be
granted  immediately upon the commencement of any such suit.  Nothing  contained
herein shall be construed as  prohibiting  the Employer  from pursuing any other
remedies  available  at law or equity for such  breach or  threatened  breach of
Section 4 or  Section  5 or for any  breach  or  threatened  breach of any other
provision  of this  Agreement.  The  obligations  contained  in Sections 4 and 5
shall,  to the extent  provided in Sections 4 and 5, survive the  termination or
expiration of the  Executive's  employment with the Employer and, as applicable,
shall be fully  enforceable  thereafter  in  accordance  with the  terms of this
Agreement.  In the event of termination  of the Employment  Period in accordance
with Section 3, the Executive  agrees to cooperate with the Employer in order to
ensure an orderly  transfer  of the  Executive's  duties  and  responsibilities.
Executive  shall pay all costs  incurred by the Employer,  including  reasonable
attorneys fees, in the enforcement of this Agreement.

     (c)  Withholding.  The  Employer  shall  withhold  such  amounts  from  any
          -----------
compensation or other benefits  payable to the Executive under this Agreement on
account of payroll  and other  taxes as may be  required  by  applicable  law or
regulation of any governmental authority.

     (d) Assignment;  Successors. This Agreement shall be binding upon and inure
         -----------------------
to the benefit of both  parties and their  respective  successors  and  assigns,
including any corporation with which or into which the Employer may be merged or
which may  otherwise  succeed  to its  assets or  business.  Consequently,  this
Agreement shall,  subject to the provisions hereof, be binding upon and inure to
the benefit of such successor and such successor shall discharge and perform all
the promises,  covenants,  duties and obligations of the Employer hereunder, and
all  references  herein  to  the  "Employer"  shall  thereafter  refer  to  such
successor.  Notwithstanding the foregoing,  the obligations of the Executive are
personal and shall not be assigned by him.

     (e) Key Man Insurance.  The Employer shall have the right to obtain key man
         -----------------
life insurance,  for the benefit of the Employer, with respect to the Executive,
and the  Executive  shall undergo such  physical  examinations  and provide such
other  cooperation  as may  reasonably  be requested by the Employer in order to
obtain and maintain such insurance.

                                       78
<PAGE>

     (f)  Indemnity.  The  Employer  hereby  agrees  to  indemnify  and hold the
          ---------
Executive  harmless  to the  maximum  degree  allowed by law against any and all
liabilities,  expenses (including attorneys' fees and costs), claims, judgments,
fines,  and amounts  paid in  settlement  actually  and  reasonably  incurred in
connection with any proceeding  arising out of the  Executive's  employment with
the Employer (whether civil,  criminal,  administrative or investigative,  other
than  proceedings  by or in the right of the  Employer),  if with respect to the
actions at issue in the  proceeding  the Executive  acted in good faith and in a
manner  Executive  reasonably  believed  to be in, or not  opposed  to, the best
interests of the Employer,  and (with respect to any criminal action)  Executive
had no reason to believe Executive's conduct was unlawful.

     (g) Acknowledgment.  The parties hereto acknowledge that Employer's general
         --------------
counsel,  Whiteford,  Taylor & Preston  L.L.P.,  has prepared this  Agreement on
behalf of the Employer and not the Executive. The Executive acknowledges that he
has been advised by the Employer to seek the advice of independent counsel prior
to reaching  agreement  with the Employer on any of the terms of this  Agreement
and that he has carefully read this Agreement,  understands its terms, consulted
with an attorney of its choice,  and  voluntarily  executes  the same as its own
free act with the intent to be legally bound thereby.  The parties agree that no
rule of construction  shall apply to this Agreement  which  construes  ambiguous
language  in favor of or  against  any party by reason of that  party's  role in
drafting this Agreement.

     (h) Waivers;  Modification.  Failure to insist upon strict  compliance with
         ----------------------
any of the terms,  covenants,  or conditions hereof shall not be deemed a waiver
of such term, covenant, or condition, nor shall any waiver or relinquishment of,
or failure to insist upon strict  compliance  with, any right or power hereunder
at any one or more times be deemed a waiver or  relinquishment  of such right or
power at any other time or times.  This  Agreement  shall not be modified in any
respect except by a writing executed by each party hereto.
