Exhibit 10.0
                             EMPLOYMENT AGREEMENT

     This  EMPLOYMENT  AGREEMENT (the  "Agreement") is entered into by and among
Washington  Gas  Light  Company  (the  "Company")  and  Patrick  J.  Maher  (the
"Executive"), as of the 19th day of May, 1997.

                                   RECITALS

     The Board of Directors of the Company (the "Board"), has determined that it
is in the best interests of the Company and its  shareholders to assure that the
Company will have the continued dedication of the Executive, notwithstanding the
possibility,  threat or occurrence of a Change of Control (as defined  below) of
the Company.  The Board  believes it is  imperative  to diminish the  inevitable
distraction of the Executive by virtue of the personal  uncertainties  and risks
created  by a pending  or  threatened  Change of Control  and to  encourage  the
Executive's  full attention and  dedication to the Company  currently and in the
event of any  threatened  or  pending  Change of  Control,  and to  provide  the
Executive with  compensation and benefits  arrangements upon a Change of Control
which ensure that the  compensation  and benefits  expectations of the Executive
will be satisfied and which are  competitive  with those of other  corporations.
Therefore,  in order to accomplish  these  objectives,  the Board has caused the
Company to enter into this Agreement.

                                   AGREEMENT

            NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

     1. Certain Definitions.  (a) The "Effective Date" shall mean the first date
during  the Change of Control  Period  (as  defined in Section  l(b)) on which a
Change of Control (as defined in Section 2) occurs.  Anything in this  Agreement
to the  contrary  notwithstanding,  if a Change  of  Control  occurs  and if the
Executive's employment with the Company is terminated within twelve months prior
to the date on which the Change of Control occurs, then for all purposes of this
Agreement the "Effective Date" shall mean the date immediately prior to the date
of such termination of employment.

     (b) The "Change of Control Period" shall mean the period  commencing on the
date hereof and ending on the second anniversary of the Effective Date.

     2.  Change of  Control.  For the  purpose of this  Agreement,  a "Change of
Control" shall mean:

          (a) The  acquisition  by any  individual,  entity or group (within the
     meaning of Section  13(d)(3) or 14(d)(2) of the Securities  Exchange Act of
     1934, as amended (the "Exchange Act")) (a "Person") of beneficial ownership
     (within the meaning of Rule 13d-3  promulgated  under the Exchange  Act) of
     30% or more of either (I) the  then-outstanding  shares of common  stock of
     the Company (the  "Outstanding  Company Common Stock") or (ii) the combined
     voting  power of the  then-outstanding  voting  securities  of the  Company
     entitled to vote generally in the election of directors  (the  "Outstanding

                                      1


     Company Voting  Securities");  provided, however, that for purposes of this
     subsection  (a),  the  following acquisitions shall not constitute a Change
     of  Control:  (I)  any  acquisition  directly  from the  Company,  (ii) any
     acquisition by the Company,  (iii) any acquisition by any employee  benefit
     plan (or related  trust)  sponsored  or  maintained  by  the Company or any
     corporation  controlled by  the  Company, or (iv) any  acquisition  by  any
     corporation pursuant to a transaction which complies with clauses (I), (ii)
     and (iii) of subsection   of this Section 2; or

          (b) Individuals who, as of the date hereof,  constitute the Board (the
     "Incumbent  Board")  cease for any reason to constitute at least a majority
     of the Board;  provided,  however,  that any individual becoming a director
     subsequent to the date hereof whose election, or nomination for election by
     the Company's  shareholders,  was approved by a vote of at least a majority
     of the directors then comprising the Incumbent Board shall be considered as
     though such individual were a member of the Incumbent Board, but excluding,
     for this purpose,  any such individual  whose initial  assumption of office
     occurs as a result of an actual or threatened election contest with respect
     to the  election  or removal of  directors  or other  actual or  threatened
     solicitation  of proxies or consents by or on behalf of a Person other than
     the Board; or

            Consummation of a reorganization,  merger or consolidation or sale
     or other  disposition  of all or  substantially  all of the  assets  of the
     Company (a "Business  Combination"),  in each case, unless,  following such
     Business  Combination,  (I) all or substantially all of the individuals and
     entities who were the beneficial owners,  respectively,  of the Outstanding
     Company Common Stock and Outstanding Company Voting Securities  immediately
     prior  to  such  Business   Combination   beneficially   own,  directly  or
     indirectly, more than 50% of, respectively, the then- outstanding shares of
     common stock and the combined voting power of the  then-outstanding  voting
     securities entitled to vote generally in the election of directors,  as the
     case may be, of the  corporation  resulting from such Business  Combination
     (including,  without  limitation,  a corporation  which as a result of such
     transaction owns the Company or all or  substantially  all of the Company's
     assets   either   directly  or  through  one  or  more   subsidiaries)   in
     substantially the same proportions as their ownership, immediately prior to
     such  Business  Combination  of the  Outstanding  Company  Common Stock and
     Outstanding  Company Voting Securities,  as the case may be, (ii) no Person
     (excluding any corporation  resulting from such Business Combination or any
     employee benefit plan (or related trust) of the Company or such corporation
     resulting from such Business  Combination)  beneficially owns,  directly or
     indirectly,  30% or more of, respectively,  the then-outstanding  shares of
     common stock of the corporation  resulting from such Business  Combination,
     or the combined voting power of the then- outstanding  voting securities of
     such corporation  except to the extent that such ownership existed prior to
     the  Business  Combination  and (iii) at least a majority of the members of
     the board of  directors of the  corporation  resulting  from such  Business
     Combination  were  members  of  the  Incumbent  Board  at the  time  of the
     execution  of the  initial  agreement,  or of  the  action  of  the  Board,
     providing for such Business Combination; or

          (d)  Approval  by  the  shareholders  of  the  Company  of a  complete
     liquidation or dissolution of the Company.

          3.  Employment  Period.  "Employment  Period"  shall  mean the  period
     commencing on the Effective  Date and ending on the second  anniversary  of
     such date.

                                      2


          4.  Terms of  Employment.  (a)  Position  and  Duties.  (I) During the
     Employment Period, the Executive's  position,  duties and  responsibilities
     shall be at  least  commensurate  in all  material  respects  with the most
     significant  of those held,  exercised  and assigned at any time during the
     120-day  period   immediately   preceding  the  Effective  Date  (it  being
     understood  that changes in reporting  relationships  or offices  shall not
     necessarily   constitute  a  material   change  in   position,   duties  or
     responsibilities) and;

          (ii)  During the  Employment  Period,  and  excluding  any  periods of
     vacation and sick leave to which the  Executive is entitled,  the Executive
     agrees to devote reasonable attention and time during normal business hours
     to the business and affairs of the Company and, to the extent  necessary to
     discharge the responsibilities  assigned to the Executive hereunder, to use
     the  Executive's   reasonable  best  efforts  to  perform   faithfully  and
     efficiently such  responsibilities.  During the Employment  Period it shall
     not be a violation  of this  Agreement  for the  Executive  to (A) serve on
     corporate,  civic or charitable boards or committees, (B) deliver lectures,
     fulfill speaking engagements or teach at educational institutions,  and  
     manage   personal   investments,   so  long  as  such   activities  do  not
     significantly   interfere   with  the   performance   of  the   Executive's
     responsibilities  as an  employee of the  Company in  accordance  with this
     Agreement.  It is expressly  understood  and agreed that to the extent that
     any such  activities  have been  conducted  by the  Executive  prior to the
     Effective Date, the continued conduct of such activities (or the conduct of
     the  activities  similar in nature  and scope  thereto)  subsequent  to the
     Effective  Date  shall  not  thereafter  be deemed  to  interfere  with the
     performance of the Executive's responsibilities to the Company.

          (b) Compensation.  (I) Base Salary.  During the Employment Period, the
     Executive shall receive an annual base salary ("Annual Base Salary"), which
     shall be paid at a monthly rate, at least equal to twelve times the highest
     monthly  base salary paid or payable,  including  any base salary which has
     been  earned  but  deferred,  to the  Executive  by  the  Company  and  its
     affiliated   companies  in  respect  of  the  12-month  period  immediately
     preceding  the  month  in which  the  Effective  Date  occurs.  During  the
     Employment Period, the Annual Base Salary shall be reviewed no more than 12
     months after the last salary increase awarded to the Executive prior to the
     Effective  Date and  thereafter at least  annually.  Any increase in Annual
     Base Salary shall not serve to limit or reduce any other  obligation to the
     Executive  under this  Agreement.  Annual Base Salary  shall not be reduced
     after any such increase and the term Annual Base Salary as utilized in this
     Agreement  shall refer to Annual Base  Salary as so  increased.  As used in
     this Agreement,  the term "affiliated  companies" shall include any company
     controlled by, controlling or under common control with the Company.

          (ii)  Annual  Incentive.  In  addition  to  Annual  Base  Salary,  the
     Executive shall have the opportunity to earn annual incentive  compensation
     (the "Annual  Incentive") for each fiscal year ending during the Employment
     Period,  at least equal to that  available to other peer  executives of the
     Company and its affiliated  companies.  Each such Annual Incentive shall be
     paid no later  than the end of the  third  month of the  fiscal  year  next
     following the fiscal year for which the Annual Incentive is awarded, unless
     the Executive shall elect to defer the receipt of such Annual Incentive. In
     the event the Executive is terminated  during the  Employment  Period,  the
     Executive's Annual Incentive for the most recent year shall be prorated for
     the portion of that year that the Executive  worked in the manner set forth
     in Section 6(a)(I)(A)(2).


                                      3


          (iii) Incentive,  Savings and Retirement Plans.  During the Employment
Period, the Executive shall be entitled to participate in all incentive, savings
and retirement plans,  practices,  policies and programs applicable generally to
other  peer  executives  of the  Company  and its  affiliated companies,  but in
no event  shall  such  plans,  practices,  policies  and  programs  provide  the
Executive with incentive  opportunities (measured with  respect  to both regular
and  special  incentive  opportunities,  to  the  extent,   if  any,   that such
distinction  is  applicable),   savings  opportunities  and  retirement  benefit
opportunities,  less favorable,  in the aggregate,  than  the  most favorable of
those provided by the Company and its  affiliated companies  for  the  Executive
under such plans, practices, policies and programs as  in  effect  at  any  time
during the  120-day  period  immediately preceding the Effective Date or if more
favorable to the Executive,  those provided  generally  at  any  time  after the
Effective  Date  to  other  peer  executives  of  the Company and its affiliated
companies.

            (iv)  Welfare  Benefit  Plans.  During  the  Employment  Period, the
Executive  and/or  the  Executive's  beneficiaries, as the case may be, shall be
eligible  for  participation  in  and  shall  receive all benefits under welfare
benefit plans, practices, policies and programs provided  by the Company and its
affiliated  companies  (including,  without  limitation,  medical, prescription,
dental, disability,  employee life,  group life,  accidental  death  and  travel
accident insurance plans and programs)  to  the  extent  applicable generally to
other peer executives of the Company  and its  affiliated  companies, but  in no
event shall such plans, practices, policies and programs provide  the  Executive
with  benefits  which  are  less  favorable,  in  the  aggregate,  than the most
favorable of such  plans,  practices,  policies and  programs in  effect for the
Executive  at  any  time  during  the 120-day  period  immediately preceding the
Effective Date or, if more  favorable to the Executive, those provided generally
at any  time  after  the  Effective Date to other peer executives of the Company
and its affiliated companies.

            (v)  Expenses.  During the Employment Period, the Executive shall be
entitled to receive prompt reimbursement for all reasonable expenses incurred by
the Executive in accordance  with  the  most  favorable  policies, practices and
procedures  of  the  Company  and  its  affiliated  companies  in effect for the
Executive  at  any  time  during  the 120-day  period  immediately preceding the
Effective Date or, if more favorable to the Executive, as in effect generally at
any time thereafter with respect to other peer executives of the Company and its
affiliated companies.

            (vi)  Fringe Benefits.  During the Employment  Period, the Executive
shall be entitled to fringe benefits, including, without  limitation, payment of
club dues, and, if  applicable,  use  of  an  automobile  and payment of related
expenses, in  accordance  with the most favorable plans, practices, programs and
policies of the Company and its affiliated companies in effect for the Executive
at any time during  the  120-day period immediately preceding the Effective Date
or, if more favorable to the Executive, as  in  effect  generally  at  any  time
thereafter  with  respect  to  other  peer  executives  of  the  Company and its
affiliated companies.

            (vii)  Office.  During the Employment Period, the Executive shall be
entitled to an office at least equal  to  that  of  other peer executives of the
Company and its affiliated companies.

            (viii)  Vacation.  During the Employment Period, the Executive shall
be entitled to  paid  vacation  in  accordance  with  the  most favorable plans,
policies, programs and practices  of the Company and its affiliated companies as
in effect for the Executive at any time during the  120-day  period  immediately

                                      4


preceding the Effective  Date or, if  more  favorable  to  the Executive,  as in
effect generally at any time thereafter with respect to other peer executives of
the Company and its affiliated companies.

     5. Termination of  Employment. (a) Death  or  Disability.  The  Executive's
employment  shall  terminate automatically upon the Executive's death during the
Employment Period.  If  the Company determines in good faith that the Disability
of the Executive  has  occurred  during  the  Employment Period (pursuant to the
definition of Disability set forth below), it may give to the Executive  written
notice in  accordance  with Section  12(b) of this Agreement of its intention to
terminate the Executive's employment. In such event, the Executive's  employment
with  the  Company  shall  terminate effective  on the 30th day after receipt of
such  notice by the  Executive (the "Disability Effective Date"), provided that,
within the 30 days after such  receipt, the Executive shall not have returned to
full-time performance of the Executive's duties. For purposes of this Agreement,
"Disability" shall mean the absence of the Executive from the Executive's duties
with the Company on a full-time basis  for  180  consecutive  business days as a
result of incapacity due to mental or physical illness which is determined to be
total and permanent by a  physician  selected by the Company or its insurers and
acceptable to the Executive or the Executive's legal representative.

     (b) Cause.  The Company may terminate the Executive's employment during the
Employment  Period  for  Cause.  For  purposes  of this Agreement, "Cause" shall
mean:

       (I)  the willful and  continued  failure  of  the  Executive  to  perform
substantially  the Executive's  duties with the Company or one of its affiliates
(other than any such failure from incapacity due to physical or mental illness),
after a written demand for substantial performance is delivered to the Executive
by the Board of the Company  which  specifically  identifies the manner in which
the  Board  believes  that  the  Executive  has  not substantially performed the
Executive's duties; provided,  however,  resignation  by  the  Executive for any
reason  (or for no express reason)  shall  not  constitute  "Cause"  under  this
Section; or

       (ii)  the willful engaging by the Executive in  illegal  conduct or gross
misconduct which is materially and demonstrably injurious to the Company.

For  purposes  of  this  provision, no act or failure to act, on the part of the
Executive,  shall be considered  "willful"  unless  it is done, or omitted to be
done, by  the  Executive  in  bad  faith  or  without reasonable belief that the
Executive's  action  or  omission  was in the  best  interests  of the  Company.
Any act, or failure to act, based upon authority given pursuant to a  resolution
duly adopted by the Board of the Company or based upon the advice of counsel for
the Company shall be conclusively presumed to be done, or omitted to be done, by
the  Executive  in  good  faith  and  in the best interests of the Company.  The
cessation of employment  of  the  Executive  shall not be deemed to be for Cause
unless and until there shall have been delivered to  the  Executive  a copy of a
resolution duly adopted by  the affirmative vote of not less than three quarters
of the entire  membership of the Board at a meeting of the Board called and held
for such  purpose (after reasonable notice is provided to  the Executive and the
Executive is given an opportunity, together with counsel, to be heard before the
Board), finding  that, in the good faith opinion of the Board,  the Executive is
guilty  of  the  conduct  described  in  subparagraph  (I)  or  (ii) above,  and
specifying the particulars thereof in detail.

                                      5


             Termination  by  Executive.  During the  Employment  Period,  the
     Executive may resign for any reason (or for no express reason).

          (d) Notice of  Termination.  Any termination by the Company for Cause,
     or by the Executive during the Employment Period,  shall be communicated by
     Notice of  Termination  to the other party hereto given in accordance  with
     Section 12(b) of this Agreement.  For purposes of this Agreement, a "Notice
     of  Termination"  means a written  notice which (I)  indicates the specific
     termination  provision in this  Agreement  relied upon,  (ii) to the extent
     applicable,  sets forth in  reasonable  detail the facts and  circumstances
     claimed to provide a basis for  termination of the  Executive's  employment
     under the provision so indicated and (iii) if the Date of  Termination  (as
     defined below) is other than the date of receipt of such notice,  specifies
     the  termination  date (which date shall be not more than 30 days after the
     giving of such notice).

          (e)  Date of  Termination.  "Date  of  Termination"  means  (I) if the
     Executive's  employment is terminated by the Company for Cause, the date of
     receipt of the Notice of Termination  or any later date specified  therein,
     as the case may be, (ii) if the Executive's employment is terminated by the
     Company other than for Cause or Disability,  the Date of Termination  shall
     be  the  date  on  which  the  Company   notifies  the  Executive  of  such
     termination, (iii) if the Executive's employment is terminated by reason of
     death or Disability,  the Date of Termination shall be the date of death of
     the  Executive or the  Disability  Effective  Date, as the case may be, and
     (iv) if the Executive  terminates his employment for any reason whatsoever,
     the Date of Termination  shall be the date on which the Executive  notifies
     Company of such termination.

          6.  Obligations  of the Company  upon  Termination  During  Employment
     Period.  (a) Other Than for Cause.  If, during the Employment  Period,  the
     Company shall terminate the Executive's  employment other than for Cause or
     the Executive shall terminate employment for any reason whatsoever:

            (I)  the Company shall pay to the Executive  in a lump  sum in  cash
      within  30  days  after  the Date of  Termination  the  aggregate  of  the
      following amounts:

                  A.  the sum of (1) the Executive's Annual Base  Salary through
            the Date of Termination to the extent not theretofore  paid, (2) the
            product  of (x) the  Target  Annual  Incentive  (as  defined  in the
            Executive Compensation  Plan of the Company)  in the  fiscal year of
            the  Executive's Termination  and (y) a fraction,  the  numerator of
            which is the  number of days in the current fiscal year  through the
            Date of Termination, and the denominator of which is 365 and (3) any
            compensation previously deferred by the Executive (together with any
            accrued interest or earnings thereon)  and any accrued vacation pay,
            in  each  case  to the extent  not therefore  paid (the  sum  of the
            amounts described in clauses (1), (2), and (3) shall be  hereinafter
            referred to as the "Accrued Obligations"); and

                  B.  Subject to the  provisions of Section 9, the  amount equal
            to three  times the Executive's  Average Pay.  For  purposes of this
            Agreement, Average Pay shall mean

                                      6


            the sum of (1) the  Executive's  Annual  Base  Salary,  plus (2)the
            Executive's  average  Annual Incentive  actually earned for the last
            three full fiscal years.


            (ii)  for three  years after the  Executive's Date  of  Termination,
      or such longer period as  may be provided by the terms of the  appropriate
      plan, program, practice or policy, the Company shall continue  benefits to
      the  Executive  and/or the  Executive's  beneficiaries  at  least equal to
      those which would have been provided to them in accordance with the plans,
      programs, practices and  policies  described in  Section 4(b) (iv) of this
      Agreement if the  Executive's  employment had  not been terminated  or, if
      more  favorable to the  Executive,  as  in  effect  generally at any  time
      thereafter  with respect  to other peer executives of the Company and  its
      affiliated  companies and  their families, provided, however, that if  the
      Executive  becomes  reemployed with  another  employer and is eligible  to
      receive medical or other welfare benefits under another  employer-provided
      plan, the medical and other  welfare  benefits  described  herein shall be
      secondary to those  provided under such other plan during  such applicable
      period of eligibility.  After  this  three-year term, the  Executive shall
      immediately be eligible for  COBRA benefits.  For purposes  of determining
      eligibility  (but  not  the  time  of  commencement  of  benefits)  of the
      Executive  for  retiree  benefits  pursuant  to  such  plans,   practices,
      programs and policies, the Executive shall be considered to  have remained
      employed  until  three years  after the  Date of Termination  and to  have
      retired on the last day of such period;

            (iii)  to the extent not theretofore paid or  provided, the  Company
      shall  timely  pay  or  provide  to  the  Executive  any  other amounts or
      benefits  required  to  be  paid or  provided or  which the  Executive  is
      eligible  to  receive  under  any  plan,  program,  policy  or practice or
      contract or agreement of the Company  and its affiliated  companies  (such
      other amounts and benefits shall be hereinafter referred to as the  "Other
      Benefits"); and

            (iv) The Company shall credit the Executive with up to an additional
      three years of benefit service under the Company's Supplemental  Executive
      Retirement Plan (the "SERP"), but in no event shall such  additional years
      of benefit service result in total years of benefit service  exceeding the
      maximum under the SERP.

          (b) Death.  If the  Executive's  employment is terminated by reason of
     the Executive's  death during the Employment  Period,  this Agreement shall
     terminate   without   further   obligations   to  the   Executive's   legal
     representatives  under this  Agreement,  other than for  payment of Accrued
     Obligations and the timely payment or provision of Other Benefits.  Accrued
     Obligations  shall be paid to the  Executive's  estate or  beneficiary,  as
     applicable,  in a  lump  sum  in  cash  within  30  days  of  the  Date  of
     Termination.  With  respect to the  provision of Other  Benefits,  the term
     Other  Benefits as utilized in this  Section  6(b) shall  include,  without
     limitation,  and the  Executive's  estate  and/or  beneficiaries  shall  be
     entitled to receive, benefits at least equal to the most favorable benefits
     provided  by the  Company  and  affiliated  companies  to the  estates  and
     beneficiaries  of  peer  executives  of the  Company  and  such  affiliated
     companies under such plans,  programs,  practices and policies  relating to
     death benefits,  if any, as in effect with respect to other peers and their
     beneficiaries at any time during the 120-day period  immediately  preceding

     the  Executive's beneficiaries, as in effect on the date of the Executive's
     death  with  respect  to  other  peer  executives  of  the  Company and its
     affiliated companies and their beneficiaries.

            Disability.  If the Executive's employment is terminated by reason
     of the Executive's  Disability during the Employment Period, this Agreement
     shall terminate  without further  obligations to the Executive,  other than
     for payment of Accrued  Obligations  and the timely payment or provision of
     Other  Benefits.  Accrued  Obligations  shall be paid to the Executive in a
     lump sum in cash within 30 days of the Date of Termination. With respect to
     the provision of Other Benefits,  the term "Other  Benefits" as utilized in
     this Section 6  shall include,  and the Executive shall be entitled after
     the Disability Effective Date to receive,  disability and other benefits at
     least  equal  to the most  favorable  of those  generally  provided  by the
     Company and its affiliated  companies to disabled  executives  and/or their
     families in accordance  with such plans,  programs,  practices and policies
     relating to  disability,  if any, as in effect  generally  with  respect to
     other peer  executives  and their  families  at any time during the 120-day
     period  immediately  preceding the Effective  Date or, if more favorable to
     the Executive  and/or the  Executive's  beneficiaries,  as in effect at any
     time  thereafter  generally  with respect to other peer  executives  of the
     Company and its affiliated companies and their families.

          (d)  Cause:  Other  than for  Change of  Control.  If the  Executive's
     employment shall be terminated for Cause during the Employment Period, this
     Agreement  shall  terminate  without  further  obligations to the Executive
     other than the  obligation  to pay to the  Executive  (x) his  Annual  Base
     Salary through the Date of Termination,  (y) the amount of any compensation
     previously deferred by the Executive,  and (z) Other Benefits, in each case
     to the extent theretofore unpaid.

          7.  Nonexclusivity 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  any  of its
     affiliated companies and for which the Executive may qualify,  nor, subject
     to Section  12(f),  shall  anything  herein limit or otherwise  affect such
     rights as the Executive  may have under any contract or agreement  with the
     Company  or any of its  affiliated  companies.  Amounts  which  are  vested
     benefits or which the Executive is otherwise  entitled to receive under any
     plan, policy,  practice or program of or any contract or agreement with the
     Company or any of its affiliated  companies at or subsequent to the Date of
     Termination shall be payable in accordance with such plan, policy, practice
     or program or contract or agreement  except as explicitly  modified by this
     Agreement.

          8. Full  Settlement.  The  Company's  obligation  to make the payments
     provided for in this  Agreement  and  otherwise to perform its  obligations
     hereunder shall not be affected by any set-off,  counterclaim,  recoupment,
     defense or other claim,  right or action which 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  whether  or not  the
     Executive obtains other employment.

          9. Certain  Additional  Payments by the Company.  (a) Anything in this
     Agreement to the contrary notwithstanding and except as set forth below, in
     the event it shall be determined that  any payment or  distribution  by the

                                      8


Company  to  or for the  benefit  of  the  Executive (whether paid or payable or
distributed  or  distributable  pursuant  to  the  terms of  this  Agreement  or
otherwise (a "Payment") would be  subject to the excise tax  imposed pursuant to
Sections 280G  and/or  4999 of  the  Code  or  any  interest  or  penalties  are
incurred by the Executive with respect  to such  excise  tax (such  excise  tax,
together  with  any  such  interest and  penalties, are hereinafter collectively
referred to  as  the "Excise Tax"), then  the  Executive  shall  be  entitled to
choose whether to  receive  (I) the amount of  such  Payment, or (ii)  a smaller
amount equal to one dollar less  than the  maximum  amount  that  Executive  may
receive  without  having  such  payment  be  treated  as   an  excess  parachute
payment  under Section  280G  of the  Code or that  may  otherwise  give rise to
Excise  Tax  (the "Reduced Amount"),  or (iii)  with  respect  to the payment in
Section 6(a) (I) (B), an amount equal to  (A) 2.0 times Average Pay, plus (B) an
amount of cash that enables the Executive to pay the Excise tax on  such amount,
plus   an amount that enables the Executive to pay all additional Excise Taxes
that may  arise due to payments to  Executive that are  made for the  purpose of
paying Excise Taxes.

          (b) In order  to  choose  among  the  benefits  described  above,  the
     calculation  of such  amounts  shall  be  computed  by an  accounting  firm
     designated by the Company (the  "Accounting  Firm").  Such  Accounting Firm
     shall provide detailed  supporting  calculations both to the Company and to
     the Executive  within 15 days of the Date of Termination.  In the event the
     Executive  chooses the benefit  described in Section  9(a)(ii)  above,  the
     Executive  shall  determine  which  benefits shall be eliminated or reduced
     consistent with the requirements of Section 9(a)(ii). If the Executive does
     not  make  such  determination  within  ten  days  of  the  receipt  of the
     calculations made by the Accounting Firm, the Company shall elect which and
     how much of the benefits shall be eliminated or reduced consistent with the
     requirements  of this Section 9 and shall notify the Executive  promptly of
     such  election.  Within five days  thereafter,  the Company shall pay to or
     distribute to or for the benefit of the Executive  such amounts as are then
     due to the Executive under this Agreement.

            In the event the Internal  Revenue  Service  ("IRS")  subsequently
     challenges the Excise Tax computation herein described,  then the Executive
     shall  notify  the  Company  in  writing  of any claim by the IRS that,  if
     successful, would require the payment by the Executive of additional Excise
     Taxes.  Such  notification  shall be given no later than ten days after the
     Executive  receives  written notice of such claim.  The Executive shall not
     pay such claim prior to the  expiration of the 30-day period  following the
     date on which the  Executive  gives  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 and
     that it will bear the costs and provide the  indemnification as required by
     this sentence, the Executive shall cooperate with the Company in good faith
     in order  effectively  to contest  such  claim and  permit  the  Company to
     participate in any proceedings relating to such claim. In the event a final
     determination  is made with  respect to the IRS claim,  or in the event the
     Company chooses not to further challenge such claim, then the Company shall
     reimburse the Executive  for the  additional  Excise Tax owed to the IRS in
     excess of the Excise Tax  calculated by the  Accounting  Firm.  The Company
     shall also  reimburse the Executive for all interest and penalties  related
     to the underpayment of such Excise Tax. The Company will also reimburse the
     Executive  for all  federal  and  state  income  tax and  employment  taxes
     thereon.

          10. Confidential Information.  The Executive shall hold in a fiduciary
     capacity  for  the  benefit  of the  Company  all  secret  or  confidential
     information,  knowledge  or  data  relating  to the  Company  or any of its
     affiliated  companies,  and their respective  businesses,  which shall have
     been obtained by the  Executive  during the  Executive's  employment by the
     Company or any of its affiliated companies and which shall not be or become
     public knowledge (other than by acts by the Executive or representatives of
     the Executive in violation of this  Agreement).  After  termination  of the
     Executive's  employment with the Company,  the Executive shall not, without
     the prior written consent of the Company or as may otherwise be required by
     law  or  legal  process,  communicate  or  divulge  any  such  information,
     knowledge or data to anyone other than the Company and those  designated by
     it. In no event  shall an  asserted  violation  of the  provisions  of this
     Section 10  constitute  a basis for  deferring or  withholding  any amounts
     otherwise payable to the Executive under this Agreement.

          11.  Successors  & Assigns.  (a) This  Agreement  is  personal  to the
     Executive and without the prior written consent of the Company shall not be
     assignable by the Executive  otherwise  than by will or the laws of descent
     and  distribution.  This  Agreement  shall  inure to the  benefit of and be
     enforceable by the Executive's legal representatives.

          (b) This  Agreement  shall inure to the benefit of and be binding upon
     the Company and its successors and assigns.

            The Company will require any  successor or any party that acquires
     control of the Company  (whether direct or indirect,  by purchase,  merger,
     consolidation  or  otherwise) to all or  substantially  all of the business
     and/or  assets of the  Company  or any party that  acquires  control of the
     Company to assume expressly and agree to perform this Agreement in the same
     manner and to the same extent that the Company would be required to perform
     it if no such  succession  had  taken  place.  As  used in this  Agreement,
     "Company" shall mean the Company as hereinbefore  defined and any successor
     to its  business  and/or  assets as aforesaid  which  assumes and agrees to
     perform this Agreement by operation of law, or otherwise.

          12.  Miscellaneous.  (a)  Governing  Law;  Headings;  Amendment.  This
     Agreement shall be governed by and construed in accordance with the laws of
     the Commonwealth of Virginia,  without  reference to principles of conflict
     of laws.  The  captions of this  Agreement  are not part of the  provisions
     hereof and shall have no force or effect. This Agreement may not be amended
     or modified  otherwise than by a written agreement  executed by the parties
     hereto or their respective successors and legal representatives.

          (b) Notices. All notices and other  communications  hereunder shall be
     in writing  and shall be given by hand  delivery  to the other  party or by
     registered or certified mail,  return receipt  requested,  postage prepaid,

     or to  such  other  address as  either  party  shall  have furnished to the
     other in writing in accordance  herewith.  Notice  and communications shall
     be effective when actually received by the addressee.

            Severability.  The invalidity or unenforceability of any provision
     of this Agreement  shall not affect the validity or  enforceability  of any
     other provision of this Agreement.

          (d)  Withholding.  The Company may withhold  from any amounts  payable
     under this Agreement such federal,  state,  local or foreign taxes as shall
     be required to be withheld pursuant to any applicable law or regulation.

          (e) Waiver.  The  Executive's or the Company's  failure to insist upon
     strict  compliance  with any provision of this  Agreement or the failure to
     assert  any  right  the  Executive  or  the  Company  may  have  hereunder,
     including,  without  limitation,  the right of the  Executive  to terminate
     employment pursuant to Section 5  of this Agreement,  shall not be deemed
     to be a waiver of such  provision or right or any other  provision or right
     under this Agreement.

          (f) At Will  Employment.  The  Executive  and the Company  acknowledge
     that, except as may otherwise be provided under any other written agreement
     between the Executive and the Company,  the  employment of the Executive by
     the Company is "at will" and, subject to Section l(a) hereof,  prior to the
     Effective  Date, the  Executive's  employment  and/or this Agreement may be
     terminated  by either the Executive or the Company at any time prior to the
     Effective  Date, in which case the Executive  shall have no further  rights
     under this  Agreement.  From and after the  Effective  Date this  Agreement
     shall supersede any other agreement between the parties with respect to the
     subject matter hereof.

          (g)  Arbitration.  In the event of any  dispute  between  the  parties
     regarding this Agreement,  the parties shall submit to binding arbitration,
     conducted in Washington,  DC or in Virginia  within 25 miles of Washington,
     DC.  The  arbitration  shall  be  conducted  pursuant  to the  rules of the
     American  Arbitration  Association.  Each of the parties  shall  select one
     arbitrator,  who shall not be related  to,  affiliated  with or employed by
     that party. The two arbitrators  shall, in turn, select a third arbitrator.
     The  decision  of any two of the  arbitrators  shall  be  binding  upon the
     parties,  and may,  if  necessary,  be reduced to  judgment in any court of
     competent   jurisdiction.   Notwithstanding  the  foregoing,   the  parties
     expressly  agree that  nothing  herein in any way  precludes  Company  from
     seeking  injunctive  relief  or  declaratory  judgement  through a court of
     competent  jurisdiction  with respect to a breach (or an alleged breach) of
     any covenant not to compete or of any confidentiality covenant contained in
     this Agreement.  In the event the Executive pursues arbitration pursuant to
     this Section  herein,  the Executive shall be compensated up to $150,000 in
     legal costs.

          (h) Pooling of  Interests  Accounting.  In the event any  provision of
     this Agreement would prevent the use of pooling of interests  accounting in
     a corporate  transaction  involving  the Company  and such  transaction  is
     contingent upon pooling of interests accounting, then that provision  shall

                                      11

     be  deemed  amended  or  revoked to the extent  required  to  preserve such
     pooling of interests.  The Executive  will,  upon  advice from the Company,
     take  (or  refrain  from  taking,  as  appropriate)  all  actions necessary
     or desirable  to ensure that pooling of interests accounting  is available.

            IN WITNESS WHEREOF, the parties hereto have executed  this Agreement
     as of the day and year first above written.
