                          FORM OF EMPLOYMENT AGREEMENT

         This EMPLOYMENT AGREEMENT ("the Agreement") is made effective January
1, 2001 between American Management Systems, Incorporated, a corporation formed
under the laws of the State of Delaware with its principal place of business at
4000 and 4050 Legato Road, Fairfax, VA 22033 ("AMS" or "the Employer"), and
[Executive's Name] ("the Employee").

         WHEREAS, AMS desires to engage the services of the Employee as
Executive Vice President, and the Employee is willing to render such services to
AMS in consideration of the terms and conditions agreed to by the parties; and

         WHEREAS, the Board of Directors of AMS ("the Board") has approved the
employment of the Employee on the terms and conditions set forth in this
Agreement;

         NOW THEREFORE, in consideration of the mutual covenants and promises
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the parties hereto, AMS agrees
to employ the Employee, and the Employee agrees to perform services for AMS as
an employee, effective as of January 1, 2001 upon the terms and conditions set
forth herein.

1.       TERM.

         The initial term of this Agreement shall end on June 30, 2002, unless
         it is terminated earlier as provided herein. Beginning on that date,
         and on each anniversary thereafter, unless it is terminated earlier as
         provided herein or AMS delivers written notice to the Employee of its
         intention not to extend the Agreement at least 90 days before such
         anniversary date, the term of this Agreement shall automatically be
         extended for one additional year. The restrictive covenants in Sections
         9 and 10 hereof shall survive the termination of this Agreement.

2.       TITLE AND DUTIES.

         The Employee shall be employed as Executive Vice President of AMS. The
         Employee shall perform such services consistent with his position as
         might be assigned to him from time to time and are consistent with the
         bylaws of AMS. The Board has appointed the Employee to serve as the
         __________________________ and shall have such responsibilities and
         authority as is commensurate with such offices and as may be prescribed
         by the Board and by-laws of AMS.

3.       LOCATION.

         The Employee's place of employment shall be the Employer's offices
         described above, or at such other location within a 25 mile radius of
         the location of the offices described above as the Board shall
         reasonably direct.

4.       EXTENT OF SERVICES.

         a.       GENERAL.

                  The Employee agrees not to engage in any business activities
                  during the term of this Agreement except those that are for
                  the benefit of AMS, and to devote his entire business time,
                  attention, skill and effort to the performance of his duties
                  under this Agreement. Notwithstanding the foregoing, the
                  Employee may engage in charitable, professional and civic
                  activities that do not impair the performance of his duties to
                  AMS, as the same may be changed from time to time. Nothing
                  contained herein shall prevent the Employee from managing his
                  own personal investments and affairs, including but not
                  limited to investing his assets in the securities of publicly
                  traded companies; provided, however, that the Employee's
                  activities do not constitute a conflict of interest, violate
                  securities laws, or otherwise interfere with the performance
                  of his duties and responsibilities as described herein. The
                  Employee agrees to adhere to AMS's published policies and
                  procedures affecting directors, officers, employees, and
                  agents and shall use his best efforts to promote AMS's
                  interest, reputation, business and welfare.

         b.       CORPORATE OPPORTUNITIES.

                  The Employee agrees that he will not take personal advantage
                  of any AMS business opportunities that arise during his
                  employment with AMS and that might be of benefit to AMS. All
                  material facts regarding such opportunities must be promptly
                  reported to the Board for consideration by AMS.

5.       COMPENSATION AND BENEFITS.

         a.       BASE SALARY.

                  The Employee's base salary for calendar year 2001 shall be
                  $375,000. The base salary shall be payable in accordance with
                  AMS's standard payroll practices. The Employee's annual base
                  salary shall be reviewed no less frequently than annually for
                  increases in the discretion of the AMS Compensation Committee
                  and/or Board, taking into account the compensation level for
                  employees with similar skills and responsibilities at
                  companies comparable to AMS, and the Employee's value to AMS
                  relative to other members of the executive management
                  committee; provided, however, that at no time during the term
                  of this Agreement shall the Employee's base salary be
                  decreased from the base salary then in effect except as part
                  of an general program of salary adjustment by AMS applicable
                  to all vice presidents and above.

         b.       INCENTIVE COMPENSATION.

                  The Employee shall participate in an incentive compensation
                  plan for the year 2001 and subsequent years. The incentive
                  compensation plan target for each year shall be reasonably
                  achievable. The incentive compensation plan for each year
                  shall provide that at least 50% of the potential payout under
                  the plan at each level of achievement

<PAGE>   3

                  is based on individual performance, and shall provide for a
                  total potential payout that is at least 200% of his base
                  salary in the case of a 2-year plan or 150% in the case of a
                  1-year plan. If the Employee's employment terminates before
                  the end of a fiscal year for any reason other than termination
                  for Cause, as defined herein, the Employee shall be entitled
                  to the incentive bonus for that year, based on actual results
                  for the entire year but prorated for the period of actual
                  employment, at the time that the incentive bonus otherwise
                  would have been paid.

                  To the extent that the Compensation Committee determines that
                  any of the foregoing objectives cannot be accomplished in a
                  manner consistent with the 1996 Incentive Compensation Plan
                  for Executive Officers (the "1996 Plan"), or would require AMS
                  to make payments that do not qualify for the exception from
                  Section 162(m) of the Internal Revenue Code for qualified
                  performance-based compensation ("Performance-Based
                  Compensation"), then, as soon as practicable but in any event
                  no later than September 30, 2001, AMS shall adopt amendments
                  to, or a supplement or replacement for, the 1996 Plan (subject
                  to shareholder approval if the Board or the Compensation
                  Committee determines that such approval is appropriate or
                  necessary) that will accomplish the foregoing objectives to
                  the greatest extent possible without requiring AMS to make any
                  payments that do not qualify as Performance-Based
                  Compensation.

         c.       ADDITIONAL COMPENSATION.

                  If the Employee is an employee in good standing of AMS on June
                  30, 2001 he shall be paid, as additional compensation, the sum
                  of $150,000 in a lump sum; provided, however, that if before
                  June 30, 2001 a change in control occurs as defined in the
                  Agreement between AMS and the Employee entered into on or
                  about September 15, 2000, styled "American Management Systems,
                  Incorporated Change In Control Executive Retention Agreement"
                  ("the Change in Control Agreement"), this payment shall be
                  increased to $450,000. If the Employee is an employee in good
                  standing of AMS on June 30, 2002 he shall be paid, as
                  additional compensation, the sum of $250,000 in a lump sum.
                  The payments described in this paragraph shall be due the
                  Employee within 30 days of the stated dates.

         d.       OTHER BENEFITS.

                  The Employee shall be entitled to paid vacation, sick leave,
                  and holiday pay in accordance with AMS's policies in effect
                  from time to time, and to participate in such life, health,
                  and disability insurance, pension, deferred compensation and
                  incentive compensation plans, stock options and awards,
                  performance bonuses and other benefits as AMS extends, as a
                  matter of policy, to its executive employees. At no time
                  during the term of this Agreement shall the Employee's
                  participation in, or benefits received under, such plans or
                  programs be reduced without the written consent of the
                  Employee except as part of a general reduction that applies to
                  substantially all employees.

<PAGE>   4

         (i)      On the date that the Employee's employment terminates for any
                  reason, regardless of the Employee's actual age he shall be
                  treated as satisfying the requirements under the AMS Retiree
                  Medical Program that he must be at least age 55 and that his
                  age plus years of AMS service must equal at least 65;
                  provided, however, that if the employee is precluded from
                  participating in said plan as described, for any reason, he
                  shall be provided with the after-tax economic equivalent of
                  the benefits he would have received under the Program. The
                  economic equivalent of the benefits he would have received
                  under the Program shall be the lowest cost that would be
                  incurred by the Employee in obtaining health insurance
                  coverage for himself and his eligible dependents that will
                  provide benefits comparable to the benefits offered under the
                  AMS Retiree Medical Program, as AMS shall modify the Program
                  from time to time, less any required contributions under the
                  Program.

         (ii)     Upon the termination of the Employee's employment for any
                  reason, if the Employee's account balance under the American
                  Management Systems, Inc. Executive Deferred Compensation Plan
                  is payable to him in a lump sum or, in the case of retirement
                  benefits, in a form elected by the Employee pursuant to
                  Section 5.4 of that Plan, under no circumstances shall 10% of
                  the Employee's account balance be retained by AMS (as
                  permitted under certain circumstances by Section 5.6 of that
                  Plan).

         (iii)    Upon the termination of the Employee's employment for any
                  reason, the Employee shall have the continued right to
                  exercise any stock options that are not forfeited for the
                  remainder of the terms of the options or, if earlier, for the
                  maximum period permitted under the AMS stock option plan under
                  which the options were granted.

e.       REIMBURSEMENT OF BUSINESS EXPENSES.

         AMS shall promptly reimburse the Employee for all reasonable travel,
         entertainment and other expenses incurred or paid by the Employee in
         connection with, or related to, the performance of his duties,
         responsibilities or services under this Agreement, upon presentation by
         the Employee of such supporting information and documentation as AMS
         may reasonably request in accordance with company policy and the
         requirements of the Internal Revenue Code.

6.       TERMINATION OF EMPLOYMENT.

         a.       TERMINATION DUE TO DEATH.

                  The Employee's employment and this Agreement shall terminate
                  immediately upon his death. If the Employee's employment is
                  terminated due to his death, his estate or his beneficiaries,
                  as the case may be, shall be entitled to:

                  (i)      payment of any unpaid portion of his base salary
                           through the effective date of such termination;

<PAGE>   5

                  (ii)     reimbursement for any outstanding reasonable business
                           expense he has incurred in performing his duties
                           hereunder;

                  (iii)    the right to elect continuation coverage of insurance
                           benefits to the extent required by law;

                  (iv)     any pension survivor benefits that may become due
                           pursuant to any employee benefit plan or program of
                           AMS; and

                  (v)      payment of any accrued but unpaid benefits, and any
                           other rights, as required by the terms of any
                           employee benefit plan or program of AMS, this
                           Agreement, or any other agreement between AMS and the
                           Employee.

b.       TERMINATION DUE TO DISABILITY.

         AMS may terminate the Employee's employment at any time if the Employee
         becomes disabled, upon written notice by AMS to the Employee. If the
         Employee's employment is terminated due to his disability, he shall be
         entitled to:

         (i)      payment of any unpaid portion of his base salary through the
                  effective date of such termination;

         (ii)     reimbursement for any outstanding reasonable business expense
                  he has incurred in performing his duties hereunder;

         (iii)    the right to elect continuation coverage of insurance benefits
                  to the extent required by law; and

         (iv)     payment of any accrued but unpaid benefits, and any other
                  rights, as required by the terms of any employee benefit plan
                  or program of AMS, this Agreement, or any other agreement
                  between AMS and the Employee.

         In addition, as soon as possible after the execution of this Agreement,
         AMS shall make available to the Employee and other similarly-situated
         employees a disability benefit, paid by AMS, that is in addition to the
         disability benefits provided under its existing disability program and
         that will be sufficient to ensure that the benefits otherwise payable
         to the Employee under the terms of that program, together with the new
         benefit and any benefits from other sources that are taken into account
         in determining the amount of benefits payable under the existing
         program, are at least 60% of his base pay and continue, during the term
         of this Agreement, for as long as he remains disabled, up to age 65.

c.       TERMINATION FOR CAUSE.

         AMS may terminate the Employee's employment at any time for Cause,
         provided that it gives written notice of termination to the Employee as
         set forth below. If the Employee's employment is terminated for Cause,
         as defined below, he shall be entitled to:

<PAGE>   6

         (i)      payment of any unpaid portion of his base salary through the
                  effective date of such termination;

         (ii)     reimbursement for any outstanding reasonable business expense
                  he has incurred in performing his duties hereunder;

         (iii)    the right to elect continuation coverage of insurance benefits
                  to the extent required by law; and

         (iv)     payment of any accrued but unpaid benefits, and any other
                  rights, as required by the terms of any employee benefit plan
                  or program of AMS, this Agreement, or any other agreement
                  between AMS and the Employee.

         For purposes of this Agreement, a termination "for Cause" shall mean:
         (1) the conviction of the Employee of, or the entry of a plea of guilty
         or nolo contendere by the Employee to, any felony or misdemeanor
         involving moral turpitude; (2) fraud, misappropriation or embezzlement
         by the Employee; (3) the Employee's willful failure, gross negligence
         or gross misconduct in the performance of his assigned duties for AMS;
         (4) the Employee's breach of a fiduciary duty to AMS; (5) any act or
         omission of the Employee not at the express direction of the board or
         other appropriate authority that reflects adversely on the integrity
         and reputation for honesty and fair dealing of AMS; or (6) the breach
         by the Employee of any material term of this Agreement.

         If AMS exercises its right to terminate the Employee for Cause, AMS
         shall: (1) give the Employee written notice of termination at least
         twenty (20) days before the date of such termination specifying in
         detail the conduct constituting such Cause; and (2) deliver to the
         Employee a copy of a resolution duly adopted by a majority of the
         entire membership of the Board, after reasonable notice to the Employee
         and an opportunity for the Employee to be heard in person by members of
         the Board, finding that the Employee has engaged in such conduct.

d.       TERMINATION WITHOUT CAUSE OR CONSTRUCTIVE TERMINATION WITHOUT CAUSE.

         AMS may terminate the Employee's employment at any time without Cause,
         provided that it gives written notice of termination at least 60 days
         before the date of such termination. If the Employee's employment is
         terminated without Cause, or if there is a constructive termination
         without Cause, as defined below, the Employee shall be entitled to
         receive from AMS the following:

         (i)      payment of any unpaid portion of his base salary through the
                  effective date of such termination;

         (ii)     reimbursement for any outstanding reasonable business expense
                  he has incurred in performing his duties hereunder;

         (iii)    the right to elect continuation coverage of insurance benefits
                  to the extent required by law;

<PAGE>   7

         (iv)     full vesting of any unexercised stock options;

         (v)      payment of any accrued but unpaid benefits, and any other
                  rights, as required by the terms of any employee benefit plan
                  or program of AMS, this Agreement, or any other agreement
                  between AMS and the Employee;

         (vi)     payment of amounts equal to any premiums for health insurance
                  continuation coverage under any AMS health plans that is
                  elected by the Employee or his beneficiaries pursuant to
                  Section 4980B of the Internal Revenue Code, at a time or times
                  mutually agreed to by the parties, but only so long as the
                  Employee is not eligible for coverage under a health plan of
                  another employer (whether or not he elects to receive coverage
                  under that plan); and

         (vii)    a severance benefit in an amount equal to 250% if such
                  termination occurs on or before June 30, 2002, and 100% if
                  such termination occurs after June 30, 2002, of the Employee's
                  annual base salary in effect immediately preceding such
                  termination, but only if (1) the Employee executes a release
                  substantially identical to the release attached hereto, (2)
                  the period for revoking such release has expired, and (3) the
                  Employee has complied with the requirements of Sections 9 and
                  10 hereof.

         AMS shall pay to the Employee 75% of the severance benefit in paragraph
         (vii) within 30 days after all of the applicable conditions are
         satisfied. The other 25% of the severance benefit shall be placed in an
         interest-bearing escrow account for 12 months. If the Employee complies
         with the covenants in Sections 9 and 10 hereof throughout that period,
         the amount credited to the account shall be paid to him within 30 days
         after the end of the period. If the Employee does not comply with the
         requirements of Sections 9 and 10 hereof throughout that period, the
         amount credited to the account shall be paid to AMS. All severance
         benefits paid to the Employee shall be paid subject to all legally
         required payroll deductions and withholdings for sums owed by the
         Employee to AMS.

         For purposes of this Agreement, constructive termination without Cause
         shall mean a termination of the Employee at his own initiative
         following the occurrence, without the Employee's prior written consent,
         of one or more of the following events not on account of Cause:

         (1)      a significant diminution in the nature or scope of the
                  Employee's authority or the duties that the Employee performs,
                  unless the Employee is given new authority or assigned new
                  duties (whichever is applicable) that are substantially
                  comparable to his previous authority and duties;

         (2)      a significant reduction in the Employee's then current base
                  salary, or a significant reduction in his opportunities for
                  earnings under his incentive compensation plans, or the
                  termination or significant reduction of any employee benefit
                  or perquisite enjoyed by him (in each case except as part of

<PAGE>   8

                  a general reduction that applies to substantially all
                  employees or participants);

         (3)      the relocation of the Employee's office from its present
                  location to a location, more than 25 miles from Fairfax,
                  Virginia, without his prior written consent; or

         (4)      the failure of AMS to obtain an assumption in writing of its
                  obligation to perform this Agreement by any successor to all
                  or substantially all of the assets of AMS within 45 days after
                  a merger, consolidation, sale or similar transaction.

         In the event the Employee is terminated without Cause or there is a
         constructive termination without Cause, each party shall provide the
         other with written notice not less than 30 days before the effective
         date of the termination of employment.

e.       VOLUNTARY TERMINATION.

         If the Employee voluntarily terminates his employment on his own
         initiative for reasons other than his death, disability, or
         constructive termination without Cause, he shall be entitled to:

         (i)      payment of any unpaid portion of his base salary through the
                  effective date of such termination;

         (ii)     reimbursement for any outstanding reasonable business expense
                  he has incurred in performing his duties hereunder;

         (iii)    the right to elect continuation coverage of insurance benefits
                  to the extent required by law; and

         (iv)     payment of any accrued but unpaid benefits, and any other
                  rights, as required by the terms of any employee benefit plan
                  or program of AMS, this Agreement, or any other agreement
                  between AMS and the Employee.

         A voluntary termination under this paragraph shall be effective upon 30
         days' prior written notice to AMS unless the parties mutually agree to
         extend the effective date.

7.       MITIGATION AND OFFSET.

         If the Employee's employment is terminated during the term of this
         Agreement pursuant to the provisions of paragraph 6.d., above, the
         Employee shall be under no duty or obligation to seek or accept other
         employment, and no payment or benefits of any kind due him under this
         Agreement shall be reduced, suspended or in any way offset by any
         subsequent employment. The obligation of AMS to make the payments
         provided for in this Agreement shall not be affected by any
         circumstance including, by way of example rather than limitation, any
         set-off, counterclaim, recoupment, defense, or other right that AMS may
         assert, or due to any other employment or source of income obtained by
         the Employee.

<PAGE>   9

8.       ENTITLEMENT TO OTHER BENEFITS.

         Except as expressly provided herein, this Agreement shall not be
         construed as limiting in any way any rights or benefits the Employee,
         his spouse, dependents or beneficiaries may have pursuant to any other
         employee benefits plans or programs.

9.       CONFIDENTIALITY.

         The Employee acknowledges that all confidential information regarding
         the business of AMS and its subsidiaries and affiliates is the
         exclusive property of AMS. On or before the date that his employment
         with AMS terminates, the Employee shall return to AMS all copies of any
         material involving such confidential information to AMS, and the
         Employee agrees that he will not, directly or indirectly, divulge or
         use such information, whether or not such information is in written or
         other tangible form. The Employee also shall return to AMS by that date
         any other items in his possession, custody or control that are the
         property of AMS. The Employee understands that even after the date that
         his employment with AMS terminates he will remain bound by the terms of
         the American Management Systems, Incorporated Intellectual Property
         Rights Agreement, the AMS Employee Confidentiality Agreement, the AMS
         Guide for Ethical Business Conduct, and the restrictive covenants
         contained herein in paragraphs 9 and 10. This paragraph is intended to
         cover confidential information of AMS that relates to the business of
         AMS that has not otherwise been made public and shall not apply to
         employee responses that may be required by proper governmental or
         judicial inquiry. No breach of this Section shall be deemed to have
         occurred unless AMS provides written notice to the Employee of the
         breach within 90 days after AMS becomes aware of it.

10.      NON-SOLICITATION.

         Effective on the date that his employment with AMS terminates and for a
         period of 12 months thereafter, the Employee shall not directly (a)
         employ or solicit for employment, or assist in any way in solicitation
         for employment, any person employed by AMS or any of its affiliates
         then or at any time within the preceding 12 months; or (b) solicit, or
         assist in any way in the solicitation of business from any of AMS's or
         its affiliates' clients or prospective clients, either for the
         Employee's own benefit or the benefit of anyone other than AMS, unless
         the business being solicited is not competitive with the services or
         products provided by AMS or its affiliates. Clause (b) shall not apply
         unless the business being solicited is in a line of business in which
         AMS was already engaged or already had under active consideration while
         the Employee was employed by AMS or is a natural extension of such a
         line business with a client that was an existing client of AMS during
         that time.

11.      EMPLOYEE REPRESENTATION.

         The Employee represents and warrants to AMS that he is not now under
         any obligation of a contractual or other nature to any person, business
         or other entity that is inconsistent or in conflict with this Agreement
         or that would prevent him from performing his obligations under this
         Agreement.

<PAGE>   10

12.      ARBITRATION.

         Any dispute or controversy arising under or in connection with this
         Agreement shall, if AMS or the Employee so elects, be settled by
         arbitration, in accordance with the Commercial Arbitration Rules
         procedures of the American Arbitration Association. Arbitration shall
         occur before a single arbitrator, provided, however, that if the
         parties cannot agree on the selection of such arbitrator within 30 days
         after the matter is referred to arbitration, each party shall select
         one arbitrator and those arbitrators shall jointly designate a third
         arbitrator to comprise a panel of three arbitrators. The decision of
         the arbitrator shall be rendered in writing, shall be final, and may be
         entered as a judgment in any court in the Commonwealth of Virginia. AMS
         and the Employee each irrevocably consent to the jurisdiction of the
         federal and state courts located in Virginia for this purpose. The
         arbitrator shall be authorized to allocate the costs of arbitration
         between the parties. Notwithstanding the foregoing, AMS, in its sole
         discretion, may bring an action in any court of competent jurisdiction
         to seek injunctive relief in order to avoid irreparable harm and such
         other relief as AMS shall elect to enforce the Employee's covenants in
         Sections 9 and 10 hereof.

13.      LEGAL EXPENSES.

         Except as provided in Section 12 hereof, if any dispute or controversy
         arises under or in connection with this agreement, AMS shall promptly
         pay all the Employee's legal fees and expenses, including, by way of
         example rather than limitation, reasonable attorneys' fees incurred by
         the Employee in seeking to obtain or enforce any right or benefit under
         this Agreement, provided, however, that this obligation of AMS shall
         not apply unless the Employee prevails in whole or in part. This
         obligation shall apply irrespective of whether the dispute or
         controversy is resolved by arbitration, litigation, or a settlement
         thereof. In addition, AMS shall pay to the Employee interest at the
         prime lending rate as announced from time to time by Citibank, N.A. on
         all or any part of any amount to be paid to the Employee hereunder that
         is not paid when due.

<PAGE>   11

14.      INDEMNIFICATION.

         a.       AMS agrees that if the Employee is made a party, or, is
                  threatened to be made a party, to any action, suit or
                  proceeding, whether civil, criminal, administrative, or
                  investigative (a "Proceeding"), by reason of the fact that he
                  is or was a director, officer or employee or AMS, or is or was
                  serving at the request of AMS as a director, officer, member,
                  employee or agent of another corporation, partnership, joint
                  venture, trust or other enterprise, including service with
                  respect to employee benefit plans, whether or not the basis of
                  such Proceeding is the Employee's alleged action in an
                  official capacity while serving as a director, officer,
                  member, employee or agent, the Employee shall be Indemnified
                  and held harmless by AMS to the fullest extent permitted or
                  authorized by AMS's certificate of incorporation and by-laws.
                  To the extent consistent with the foregoing, this obligation
                  to indemnify the Employee and hold him harmless shall continue
                  even if he has ceased to be a director, officer, member,
                  employee or agent of AMS or other such entity described above,
                  and shall inure to the benefit of the Employee's heirs,
                  executors and administrators. AMS shall advance to the
                  Employee all reasonable costs and expenses incurred by him in
                  connection with a Proceeding within 20 days after receipt by
                  AMS of a written request for such advance. Such request shall
                  include an undertaking by the Employee to repay the amount of
                  such advance if it shall ultimately be determined that the
                  Employee is not entitled to be indemnified against such costs
                  and expenses.

         b.       Neither the failure of AMS (including its Board, independent
                  legal counsel or stockholders) to have made a determination
                  before such Proceeding concerning payment of amounts claimed
                  by the Employee under the subparagraph above that
                  indemnification of the Employee is proper because he has met
                  the applicable standards of conduct, nor a determination by
                  AMS (including its Board, independent legal counsel or
                  stockholders) that the Employee has not met such applicable
                  standards of conduct, shall create a presumption that the
                  Employee has not met the applicable standards of conduct.

15.      ASSIGNABILITY AND BINDING NATURE.

         This Agreement shall be binding upon and inure to the benefit of the
         parties and their respective successors, heirs (in the case of the
         Employee) and assigns. No rights or obligations may be assigned or
         transferred by AMS except that such rights or obligations may be
         assigned or transferred pursuant to a merger or consolidation in which
         AMS is not the continuing entity, or the sale or liquidation of all or
         substantially all of the assets of AMS, provided that the assignee or
         transferee is the successor to all or substantially all of the assets
         of AMS and such assignee or transferee assumes the liabilities,
         obligations, and duties of AMS, as contained in this Agreement, either
         contractually, or as a matter of law. AMS further agrees, that in the
         event of a sale of assets or liquidation as described in the foregoing
         sentence, it shall take whatever action it is legally entitled to take
         in order to Cause the assignee or transferee to expressly assume the
         liabilities, obligations, and duties of AMS under this Agreement.
         Notwithstanding any such assignment, AMS shall not be relieved from
         liability under this Agreement. No rights or obligations of the
         Employee

<PAGE>   12

         under this Agreement may be assigned or transferred by the Employee
         other than his right to receive compensation and benefits, provided
         such assignment or transfer is otherwise permitted by law.

16.      NOTICES.

         All notices required or permitted hereunder shall be in writing and

21.      ENTIRE AGREEMENT.

         Except for other agreements specifically referenced herein, this
         Agreement constitutes the entire agreement between AMS and the Employee
         and supersedes all prior agreements and understandings, whether written
         or oral relating to the subject matter hereof.

22.      SEVERABILITY.

         In case any provision hereof shall be held by a court or arbitrator
         with jurisdiction over AMS or the Employee to be invalid, illegal or
         otherwise unenforceable, such provision shall be restated to reflect as
         nearly as possible the original intentions of AMS and the Employee in
         accordance with applicable law, and the validity, legality and
         enforceability of the remaining provisions shall in not way be affected
         or impaired thereby.

23.      WAIVER.

         No delays or omission by AMS or the Employee in exercising any right
         hereunder shall operate as a waiver of that or any other right. A
         waiver or consent given by AMS or the Employee or any one occasion
         shall be effective only in that instance and shall not be construed as
         a bar or waiver of any right on any other occasion.

24.      GOVERNING LAW.

         This Agreement shall be construed, interpreted and enforced in
         accordance with the laws of the Commonwealth of Virginia, without
         regard to its conflicts of laws principles.

25.      SUCCESSORS AND ASSIGNS.

         This Agreement shall be binding upon and inure to the benefit of both
         AMS and the Employee and their respective successors and assigns,
         including any entity with which or into which AMS might be merged or
         that might succeed to its assets or business or any entity to which AMS
         might assign its rights and obligations hereunder; provided, however,
         that the obligations of the Employee are personal and shall not be
         assigned or delegated by him.

<PAGE>   14

26.      WITHHOLDING.

         AMS may make any appropriate arrangements to deduct from all benefits
         provided hereunder any taxes reasonably determined to be required to be
         withheld by any government or government agency. The Employee shall
         bear all taxes on benefits provided hereunder to the extent that no
         taxes are withheld, irrespective of whether withholding is required.

27.      COUNTERPARTS.

         This Agreement may be executed in two or more counterparts, each of
         which shall be deemed an original but all of which together shall
         constitute one and the same instruments.

28.      CONSTRUCTION WITH PRE-EXISTING CHANGE IN CONTROL RETENTION AGREEMENT

         The Change in Control Agreement referenced above is incorporated herein
         by reference. If as a result of his termination of employment following
         a Change in Control the Employee would otherwise be entitled to receive
         both the benefit provided in Section 2 of the Change in Control
         Agreement and the severance benefit provided in Section 6.d. hereof,
         the Employee shall instead receive the greater of the two benefits, and
         not both.

IN WITNESS WHEREOF, AMS and the Employee have executed this Agreement effective
as of January 1,2001.
