           (4) No employees of the Company are represented by any labor union or

     progress.

           (5) The Company has not received or been notified of any
     discrimination complaint filed by any employee, applicant, union, or other
     party with any Government Authority.

           (6) The Company has filed all required reports and information that

     4.18  Benefit Plans; ERISA Compliance.  Except as set forth on Exhibit 
           -------------------------------                          -------
4.18:
----

           (1) Schedule 4.18 contains a list of all "employee pension benefit 
               -------------             
     plans" (as defined in Section 3(2) of Employee Retirement Income Security
     Act of 1974, as amended ("ERISA")) (sometimes referred to in this Section
                               -----                                   -------
     4.18 as "Pension Plans"), "employee 
     ----     -------------   
<PAGE>
 
     welfare benefit plans" (as defined in Section 3(1) of ERISA) (sometimes
     referred to in this Section 4.18 as "Welfare Plans") and all other Benefit 
                         ------------     -------------
     Plans, as defined below, currently maintained in whole or in part,
     contributed to, or required to be contributed to by the Company for the
     benefit of any present or former officer, employee or director of the
     Company. For purposes of this Agreement, the term "Benefit Plan" shall mean
                                                        ------------
     any collective bargaining agreement or any bonus, pension, profit sharing,
     deferred compensation, incentive compensation, stock ownership, stock
     purchase, stock option, phantom stock, retirement, vacation, severance,
     disability, death benefit, hospitalization, medical, dependent care,
     cafeteria, employee assistance, scholarship or other plan, program,
     arrangement or understanding (whether or not legally binding) maintained in
     whole or in part, contributed to, or required to be contributed to by the
     Company for the benefit of any present or former officer, employee or
     director of the Company which is not a Pension Plan or Welfare Plan. The
     Company has delivered to SM&A true, complete and correct copies of (i) each
     Pension Plan, Welfare Plan and Benefit Plan (or, in the case of any
     unwritten Benefit Plans, descriptions thereof) and all amendments (none of
     which amendments will materially increase to costs of the amended plan),
     (ii) the three annual reports on Form 5500 most recently filed with the
     Internal Revenue Service (the "IRS") with respect to each Pension Plan or 
                                    ---                       
     Welfare Plan (if any such report was required), (iii) the most recent IRS
     determination letter request for each Pension Plan intended to be qualified
     under Section 401(a) of the Code and all rulings or determinations
     concerning such Pension Plan requested of the IRS subsequent to the date of
     that letter, (iv) the most recent actuarial report for each Pension Plan
     and Welfare Plan for which an actuarial report is required by ERISA, (v)
     the most recent summary plan description for each Pension Plan and Welfare
     Plan for which such summary plan description is required by ERISA and each
     summary of material modifications prepared, as required by ERISA, after the
     last summary plan description, (vi) each trust agreement and/or group
     annuity contract relating to any Benefit Plan, and (vii) all other
     information reasonably requested by SM&A.

           (2) Each Pension Plan maintained and each pension plan formerly
     maintained that is or was intended to be qualified under Section 401(a) of
     the Code has been the subject of a determination letter from the IRS to the
     effect that such plan is qualified under Section 401(a) of the Code or can
     still be submitted in a timely manner to the IRS for such a letter, and no
     such determination letter has been revoked nor has revocation of any such
     letter been threatened, nor has any such plan been amended since the date
     of its most recent determination letter or application therefor in any
     respect that would adversely affect its qualification or materially
     increase its costs, and nothing has occurred or failed to occur which would
     cause the loss of such qualification, and all amendments required to be
     adopted before the Effective Time for any such Pension Plan to continue to
     be so qualified have been or will be duly and timely adopted; provided
     however, that to the extent that this representation applies to terminated
     pension plans, this representation refers to the qualified status of any
     such plan through the time of its termination. To the best Knowledge of the
     Company, the Company has paid all premiums (including any applicable
     interest, charges and penalties for late payment) due the Pension Benefit
     Guaranty Corporation (the "PBGC") with respect to each such Pension Plan
                                ----                                       
     for which premiums to the PBGC are required and no such Pension Plan in
     whole or in part maintained by the Company has been terminated or partially
     terminated under circumstances which would result in liability to the PBGC.

           (3) Except as set forth on Schedule 4.18, each of the Pension Plan, 
                                      -------------                
     Welfare Plan and Benefit Plans sponsored by, and each of the benefit plans
     formerly sponsored by the Company: (i) has been in substantial compliance
     with all reporting and disclosure requirements of (x) Part 1 or Subtitle B
     of Title I of ERISA, if applicable, or (y) other applicable law, (ii) has
     had the appropriate required Form 5500 (or equivalent annual report) filed
     timely with the appropriate governmental entity for each year of its
     existence, (iii) has
<PAGE>
 
     at all times complied with the bonding requirements of (x) Section 412 of
     ERISA, if applicable, or (y) other applicable law, (iv) has no issue
     pending (other than the payment of benefits in the normal course) nor any
     issue resolved adversely to the Company which may subject the Company to
     the payment of penalty, interest, tax or other obligation that can be
     expected to have a Material Adverse Effect on the Company, nor is there any
     basis for any imposition of any such liability, and (v) has been maintained
     in all respects in compliance with the applicable requirements of ERISA,
     the Code and other applicable law not otherwise covered hereunder so as not
     to have any Material Adverse Effect on the Company.

           (4) All voluntary employee benefit associations maintained by the
     Company and intended to be exempt from federal income tax under Section
     501(c)(9) of the Code have been submitted to and approved as exempt from
     federal income tax under Section 501(c)(9) of the Code by the IRS, and, to
     the best Knowledge of the Company, nothing has occurred or failed to occur
     which would cause the loss of such exemption.

           (5) The execution of this Agreement or the consummation of the
     transactions contemplated by this Agreement will not give rise to any, or
     trigger any, change of control, severance or other similar provisions in
     any Pension Plan, Welfare Plan or Benefit Plan. The consummation of any
     transaction contemplated by this Agreement will not result in any (i)
     payment (whether of severance pay or otherwise) becoming due from the
     Company to any officer, employee, former employee or director thereof or to
     the trustee under any "rabbi trust" or similar arrangement; (ii) benefit
     under any Benefit Plan of the Company being established or becoming
     accelerated, vested or payable; or (iii) payment or series of payments by
     the Company, directly or indirectly, to any person that would constitute a
     "parachute payment" within the meaning of Section 280G of the Code.

           (6) The Company provides no material post-retirement medical, health,
     disability or death protection coverage or contributes to or maintains any
     employee welfare benefit plan which provides for medical, health,
     disability or death benefit coverage following termination of employment by
     any officer, director or employee except as is required by Section 4980B(f)
     of the Code or other applicable statute, nor has it made any
     representations, agreements, covenants or commitments to provide that
     coverage.

           (7) No Pension Plan or pension plan subject to Tile IV of ERISA (i)
     that the Company maintains or maintained, or (ii) to which the Company is
     or was obligated to contribute, other than any such plan that is or was a
     "multiemployer plan" (as such term is defined in Section 4001(a)(3) of
     ERISA) had, as of its most recent annual valuation date, an "unfunded
     benefit liability" (as such term is defined in Section 4001(a)(18) of
     ERISA), based on actuarial assumptions which have been furnished to SM&A.
     None of such plans subject to Section 302 of ERISA has an "accumulated
     funding deficiency" (as such term is defined in Section 302 of ERISA),
     whether or not waived. The Company, any officer of the Company, or any of
     the Pension Plan or Welfare Plans (including the Pension Plans and prior
     pension plans) which are subject to ERISA, or any trusts created
     thereunder, or any trustee or administrator thereof, has engaged in a
     "prohibited transaction" (as such term is defined in Section 406, 407 or
     408 of ERISA or Section 4975 of the Code) or any other breach of fiduciary
     responsibility that could subject the Company or any officer of the Company
     to the tax or penalty on prohibited transactions imposed by such Section
     4975 of the Code or to any liability under ERISA which would have a
     Material Adverse Effect on the Company. To the best Knowledge of the
     Company, no "reportable event" (as that term is defined in Section 4043 of
     ERISA) with respect to which the thirty (30)-day notice requirement has not
     been waived has occurred and is continuing with respect to any such Pension
     Plan, other than as may arise as a result of the consummation of the
     Merger. The Company has not suffered a "complete withdrawal" or a "partial
     withdrawal" (as such terms are defined in Section 4203 and Section 4205,
     respectively, of ERISA) since the effective date of such Sections 4203 and
<PAGE>
 
     4205 for which the Company has any liability outstanding that can be
     expected to have a Material Adverse Effect on the Company.

           (8) With respect to any Welfare Plan, (i) each such Welfare Plan that
     is a group health plan, as such term is defined in Section 5000(b)(1) of
     the Code, complies in all material respects with any applicable
     requirements of Part 6 of Title I of ERISA and Section 4980B(f) of the Code
     and (ii) each such Welfare Plan (including any such plan covering retirees
     or other former employees) may be amended or terminated with respect to
     health benefits without having a Material Adverse Effect on the Company on
     or at any time after the Consummation Date.

           (9) All contributions required by law or by a collective bargaining
     or other agreement to be made under the Pension Plan, Welfare Plan or
     Benefit Plans with respect to all periods through the Effective Date of the
     Merger, including a pro rata share of contributions due for the current
     plan year, will have been made by such date or provided for by adequate
     reserves by the Company. No changes in contribution rates or benefit levels
     have been implemented or negotiated (but not yet implemented), with respect
     to any Pension Plan, Welfare Plan or Benefit Plan since the date on which
     the information provided in the attached schedule has been provided, and no
     such changes are scheduled to occur.

          (10) The Company has not and will not have any liability or obligation
     for taxes, penalties, contributions, losses, claims, damages, judgments,
     settlement costs, expenses, costs, or any other liability or liabilities of
     any nature whatsoever arising out of or in any manner relating to any
     Pension Plan, Welfare Plan or Benefit Plan (including but not limited to
     employee benefit plans such as foreign plans which are not subject to
     ERISA), that has been, or is, contributed to by any entity, whether or not
     incorporated, which is deemed to be under common control (as defined in
     Section 414 of the Code), with the Company that can be expected to have a
     Material Adverse Effect on the Company, except to the extent they relate to
     benefits payable in the ordinary course.

          (11) The Company has not violated any of the health care continuation
     coverage requirements of the Consolidated Omnibus Budget Reconciliation Act
     of 1985 ("COBRA") applicable to its employees prior to the Effective Time
               -----                                                          
     of the Merger.

           -------------------------------------------------

                                     ---------------------

ordinance, ruling, directive, or regulation or under any order, award, judgment
or decree of any court or federal, state, municipal or other governmental
department, commission, board, bureau, agency or instrumentality having
jurisdiction over the Company or any of its assets or its business, except where
the failure to so comply or the default thereunder would not have a Material
Adverse Effect on the Company.  There are no claims, actions, suits or
proceedings, pending or, to the Knowledge of the Company threatened, against or
affecting the Company, at law or in equity, in any court, or before or by any
federal, state, municipal or other governmental department, commission, board,
bureau, agency or instrumentality having jurisdiction over the Company or its
business and no notice of any such claim, action, suit or proceeding, whether
pending or threatened, has been received.

     claim, whether pending or threatened, for Taxes has been received and not
     paid. The Company is not a party to any Tax allocation or sharing agreement
     (i.e., any agreement or arrangement for the payment of Tax liabilities or
     payment for Tax benefits with respect to a consolidated, combined or
     unitary Tax Return which includes the Company); there are no requests for
     rulings in respect of any Tax pending by the Company with any tax
     authority; and no penalty or deficiency in respect of any Taxes which has
     been assessed against the Company remains unpaid. The amounts shown as
     accruals for Taxes on the financial statements of the Company as of the
     Balance Sheet Date delivered to SM&A as a part of Schedule 4.9 are
                                                       ------------    
     sufficient for the payment of all Taxes of all kinds (including penalties

     any Tax incurred by the Company directly or indirectly as a result of the
     Merger failing to qualify as a "reorganization" within the meaning of
     Section 368(a) of the Code.  "Tax Return" shall mean any return, report or
                                   ----------                                  
     similar statement required to be filed with respect to any Tax (including

     return, claim for refund, amended return and declaration of estimated Tax.

           (2) No shareholder of the Company is a foreign person subject to

     other payments and paid over to the proper taxing authorities all amounts
     required to be so withheld and paid over for all periods under all
     applicable laws or it has finally resolved and fully satisfied any
     liability for any failure to comply with any such matters.
 
           (4) There is no pending claim by any taxing authority in any

           --------------------      -----------------                   
     commencement of any action, suit or proceeding by a person not a party to
     this Agreement in respect of which the indemnified party will seek
     indemnification hereunder (a "Third Party Action"), the indemnified party
                                   ------------------                         
     shall notify the person that is obligated to provide such indemnification
     (the "indemnifying party") thereof in writing, but any failure to so notify
           ------------------                                                   
     the indemnifying party shall not relieve it from any liability that it may
     have to the indemnified party under Section 10.2 or 10.3, except to the
                                         --------------------               
     extent that the indemnifying party is prejudiced by the failure to give
     such notice.  The indemnifying party shall be entitled to participate in
     the defense of such Third Party Action and to assume control of such
     defense (including settlement of such Third Party Action) with counsel
     reasonably satisfactory to such indemnified party; provided, however, that:
                                                        --------  -------       

               (1) the indemnified party shall be entitled to participate in the
          defense of such Third Party Action and to employ counsel at its own
          expense (which shall not constitute Legal Expenses for purposes of
          this Agreement) to assist in the handling of such Third Party Action;

               (2) the indemnifying party shall obtain the prior written
          approval of the indemnified party before entering into any settlement
          of such Third Party Action or ceasing to defend against such Third
          Party Action, if pursuant to or as a result of such settlement or
          cessation, injunctive or other equitable relief would be imposed
          against the indemnified party or the indemnified party would be
          adversely affected thereby;

               (3) no indemnifying party shall consent to the entry of any
          judgment or enter into any settlement that does not include as an
          unconditional term thereof the giving by each claimant or plaintiff to
          each indemnified party of a release from all liability in respect of
          such Third Party Action; and

               (4) the indemnifying party shall not be entitled to control the
          defense of any Third Party Action unless the indemnifying party
          confirms in writing its assumption of such defense and continues to
          pursue the defense reasonably and in good faith.  After written notice
          by the indemnifying party to the indemnified party of its election to
          assume control of the defense of any such Third Party Action in
          accordance with the foregoing, (i) the indemnifying party shall not be
          liable to such indemnified party hereunder for any Legal Expenses
          subsequently incurred by such indemnified party attributable to
          defending against such Third Party Action, and 
<PAGE>
 
          (ii) as long as the indemnifying party is reasonably contesting such
          Third Party Action in good faith, the indemnified party shall not
          admit any liability with respect to, or settle, compromise or
          discharge the claim underlying, such Third Party Action without the
          indemnifying party's prior written consent. If the indemnifying party
          does not assume control of the defense of such Third Party Action in
          accordance with this Section 10.4, the indemnified party shall have 
                               ------------
          the right to defend and/or settle such Third Party Action in such
          manner as it may deem appropriate at the cost and expense of the
          indemnifying party, and the indemnifying party will promptly reimburse
          the indemnified party therefor in accordance with this Section 10.4.
                                                                 ------------
          The reimbursement of fees, costs and expenses required by this Section
                                                                         -------
          10.4 shall be made by periodic payments during the course of the
          ----
          investigation or defense, as and when bills are received or expenses
          incurred.

          (2) If an indemnified party has actual knowledge of any facts or
     circumstances other than the commencement of a Third Party Action which
     cause in good faith it to believe that it is entitled to indemnification
     under this Article 10 then such indemnified party shall promptly give the
                ----------                                                    
     indemnifying party notice thereof in writing, but any failure to so notify
     the indemnifying party shall not relieve it from any liability that it may
     have to the indemnified party under Section 10.2 or 10.3, as the case may
                                         --------------------                 
     be, except to the extent that the indemnifying party is prejudiced by the
     failure to give such notice.

          (3) If any dispute arises concerning the representations and
     warranties contained in Section 4.8 either SM&A or the Principal
                             -----------                             
     Shareholders shall, as the case may be, send a notice to the other party
     concerning such dispute and the parties shall attempt to resolve all of the
     objecting party's objections within twenty (20) days of delivery of such
     notice.  If any objections remain unresolved after the end of such twenty
     (20) day period, SM&A and the Principal Shareholders shall appoint a

     11.1 Prohibited Activities of the Principal Shareholders.  Each Principal
          ---------------------------------------------------

               (1) For a  period ending on the later of (A) three (3) years
          after the date of this Agreement first set forth above, and (B) one
          (1) year after the (x) termination or (y) expiration of the Employment
          Term of the Employment Agreement of each Principal Shareholder (except
          as set forth in the following paragraph), each Principal Shareholder
          shall not for any reason whatsoever, directly or by other means with
          intent, for himself or on behalf of or in conjunction with any other
          Person, engage, as an officer, director, shareholder, owner, partner,
          joint venturer, lender or in any capacity, whether as an employee,
          independent contractor, consultant or advisor, or as a sales
          representative, in any business selling any products or services in
          direct or indirect competition with the Company or SM&A on the Closing
          Date;
<PAGE>
 
          Notwithstanding the foregoing provisions of this paragraph (a) each
     Principal Shareholder may (i) be a passive investor owning no more than
     five percent (5%) of the outstanding equity securities of any corporation
     the equity securities of which are listed on a national securities exchange
     or traded on the NASDAQ National Market and with which such Principal
     Shareholder has no other connection whatsoever or (ii) invest in or act as
     an employee, consultant or other position for SM&A, or any of its
     Affiliates; or

               (2) For a  period ending on the later of (A) three (3) years
          after the date of this Agreement first set forth above, and (B) one
          (1) year after the (x) termination or (y) expiration of the Employment
          Term of the Employment Agreement of each Principal Shareholder, each
          Principal Shareholder shall not, directly or by other means with
          intent, offer to employ any person who is, at that time, or who has
          been within one (1) year prior to that time, an employee of SM&A, or
          the Company.  For the purposes of this Section 11.1 general
                                                 ------------        
          advertising concerning available employment opportunities through
          newspapers or trade journals shall not constitute solicitation.

     11.2 Prohibited Activities of SM&A and Newco. In the event the Closing does
          ---------------------------------------                       
not occur for any reason, for a period of one (1) year after the date of this
Agreement, each of SM&A and Newco shall not for any reason whatsoever, solicit
the employment of any person who is, at that time, or who has been within one
(1) year prior to that date, an employee of the Company. For the purposes of
this Section 11.2 general advertising concerning available employment
     ------------                                                    
opportunities through newspapers or trade journals shall not constitute
solicitation.

     11.3 Acknowledgments.   The parties hereto agree and acknowledge that the
          ---------------                                                     
damages that would be suffered by a nonbreaching party as a result of any breach
of the provisions of this Article 11 may not be calculable and that an award of
                          ----------                                           
a monetary judgment for such a breach would be an inadequate remedy.
Consequently, a nonbreaching party shall have the right, in addition to any
other rights it may have, to obtain, in any court of competent jurisdiction,
injunctive relief to restrain any breach or threatened breach of any provision
of this Article 11 or otherwise to specifically enforce any of the provisions
        ----------                                                           
hereof, and a nonbreaching party shall not be obligated to post a bond or other
security in seeking such relief.  This remedy is in addition to damages directly
or indirectly suffered by a nonbreaching party and reasonable attorneys' fees;
and

          (1) The parties hereto agree that the restraint, duration and area for
which the covenants in this Article 11 are to be effective are reasonable in
                            ----------                                      
light of the business and activities of the parties hereto.  In the event that
any court finally determines that the time period or the geographic scope of any
such covenant is unreasonable or excessive and any covenant is to that extent
made unenforceable, the parties agree that the restrictions in this  Article 11
                                                                     ----------
shall remain in full force and effect for the greatest time period and within
the greatest geographic area that would not render it unenforceable.  The
parties intend that each of the covenants in Article 11 shall be deemed to be a
                                             ----------                        
separate covenant.

     11.4 Independent Covenant.  All of the covenants in this Article 11 shall
          --------------------                                ---------- 
be construed as an agreement independent of any other provision of this
Agreement, and the existence of any claim or cause of action of a nonbreaching
party against a breaching party, whether predicated on this Agreement or
otherwise, shall not constitute a defense to the enforcement by any party of
such covenants.
