                                   BACKGROUND
                                   ----------

          Buyer desires to purchase, and Stockholders desire to sell, all of the
Shares upon the terms hereinafter set forth in this Agreement.

          NOW THEREFORE, in consideration of the premises and of the mutual
covenants hereinafter set forth, the parties hereto, intending to be legally
bound, hereby agree as follows:

1.        Acquisition of Stock.  At the Closing (as hereinafter defined),
          --------------------
Stockholders shall sell, convey, transfer and assign to Buyer the Shares, free
and clear of all liens, security interests, pledges, claims and encumbrances of
every kind, nature and description.

2.        Purchase Price; Adjustment.
          --------------------------
(a)            In consideration of the sale, conveyance, transfer and assignment
of the Shares to Buyer, Buyer shall pay Stockholders the following (the
"Purchase Price"):

(i)              at the Closing, the sum of $3,000,000 shall be payable by wire
transfer, pursuant to the wire transfer instructions attached as Schedule
                                                                 --------
2(a)(i), to be allocated among Stockholders in accordance with the percentages
-------
set forth opposite each Stockholders name on Schedule 4(a);
                                             -------------
<PAGE>

(ii)      the sum of $1,000,000 shall be payable by delivery as soon as
practicable after the Closing of certificates evidencing that number of shares
of common stock of Parent (the "Common Shares") representing a value of
$1,000,000, based on the average of the closing price of the Common Shares for
the twenty business days immediately preceding the Closing Date, to be allocated
among Stockholders in accordance with the percentages set forth opposite each
Stockholder's name Schedule 4(a); and
                   -------------

(iii)     the sum of $750,000 shall be payable by wire transfer to the bank and
account designated by Stockholders in writing, to be allocated among
Stockholders in accordance with the percentages set forth opposite each
Stockholders name on Schedule 4(a), ten (10) days after the final determination
                     -------------
of the Closing Tangible Net Worth (as defined herein).

(b)     It is the intention of the parties that Corporation's Net Worth (as
hereinafter defined) at the Closing (the "Closing Tangible Net Worth") be equal
to or greater than $2,000,000. If the Closing Tangible Net Worth is determined
to be less than $2,000,000, any such deficiency shall be paid by Stockholders to
Buyer by wire transfer of immediately available funds to the bank and account
designated by Buyer in writing, (A) if no amounts or items shown on the Tangible
Net Worth Statement (as hereinafter defined) have been disputed as provided
herein, within 10 days after delivery to Stockholders of the Tangible Net Worth
Statement, and (B) if any amounts or items shown on the Tangible Net Worth
Statement have been disputed, within 10 business days following the resolution
of all such disputed amounts or items as provided herein. As used in this
Agreement, the term "Tangible Net Worth" means the amount by which the sum of
the book value of the assets (excluding goodwill and other intangible assets) of
Corporation exceeds the sum of the book value of the liabilities of Corporation,
calculated in accordance with generally accepted accounting principles ("GAAP"),
consistently applied. Within ninety 90 days following the Closing Date,
Stockholders and Stockholders' independent public accountants shall prepare and
deliver to Buyer a statement setting forth the Closing
<PAGE>

Tangible Net Worth (the "Tangible Net Worth Statement"). During such period of
90 days, Buyer shall provide Stockholders and Stockholders' accountants
reasonable access during normal business hours, upon reasonable advance notice,
to the books and records of Corporation; provided, however, that Stockholders
                                         --------  -------
shall schedule such access through an authorized representative of Buyer and in
such a way as to avoid material disruption of the normal business of
Corporation. For a period of 60 days after the date of delivery to Buyer of the
Tangible Net Worth Statement, Stockholders shall provide Buyer and Buyer's
accountants reasonable access during normal business hours, upon reasonable
advance notice, to the work papers used by Stockholders and Stockholders'
accountants in preparing the Tangible Net Worth Statement. Unless Buyer notifies
Stockholders in writing within 60 days after delivery to Buyer of the Tangible
Net Worth Statement that Buyer disputes one or more amounts or items shown on
the Tangible Net Worth Statement, the Tangible Net Worth Statement shall be
final, conclusive and binding on the parties hereto. If Buyer notifies
Stockholders in writing within 60 days after delivery to Buyer of the Tangible
Net Worth Statement that Buyer disputes one or more amounts or items shown on
the Tangible Net Worth Statement, then Buyer and Stockholders shall promptly
thereafter meet in good faith to attempt to resolve any and all such disputed
amounts or items. If Buyer and Stockholders are unable to agree upon a
resolution of any disputed amount within 15 days after receipt by Buyer of
Stockholders' notice regarding the existence of such disputed amount or item,
then such disputed amount or item shall be resolved by an independent nationally
recognized accounting firm, selected by mutual agreement of Buyer and
Stockholders, which is not then providing, and has not provided during the one-
year period immediately preceding the Closing Date, services to any of (i)
Buyer, or any of its affiliates or (ii) Corporation, or any of its affiliates (
"Independent Accountants"). If Buyer and Stockholders are unable to agree on
mutually acceptable Independent Accountants during the 15 day period referred to
in the immediately preceding sentence, then such Independent Accountants shall
be
<PAGE>

selected by mutual agreement of Buyer's independent public accountant and
Stockholders' independent public accountant. The resolution of such disputed
amounts and items by the Independent Accountants shall be final, conclusive and
binding upon the parties. The fees and expenses of the Independent Accountants
shall be borne equally by Buyer and Stockholders.

agreement substantially in the form attached hereto as Exhibit "A" (the "Eigen

adversely affect its qualification or tax-exempt status.

Agreement and the consummation of the transactions contemplated hereby do not
constitute a triggering event under any Plan, policy, arrangement, statement,

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

resale that, in the opinion of Stockholders' counsel, which opinion is
satisfactory to Parent, may be made without violating the registration
provisions of the Securities Act of 1933, as amended (the "Securities Act"), or
applicable state securities laws. The Common Shares are "restricted securities"
within the meaning of Rule 144 under the Securities Act and have not been
registered under the Securities Act and therefore must be held indefinitely
unless they are subsequently registered under the Securities Act or an exemption
from registration is available.

(ii)      Each Stockholder understands that there shall be endorsed on the
certificate evidencing the Common Shares issued pursuant to this Agreement a
legend substantially similar to the following:

     LAWS OF ANY OTHER JURISDICTION AND ARE "RESTRICTED SECURITIES" AS DEFINED
     BY RULE 144 UNDER THE 1933 ACT. THE SHARES MAY NOT BE SOLD, TRANSFERRED,
     PLEDGED OR DISTRIBUTED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
     STATEMENT REGISTERING THE SHARES UNDER THE 1933 ACT, OR IN LIEU THEREOF, AN
     OPINION OF COUNSEL, WHICH OPINION IS SATISFACTORY TO THE ISSUER OF THE
     SHARES, TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT."

any
<PAGE>

Reportable Event which has not been properly reported; (vi) that concern any
liability to the PBGC under Title IV of ERISA; (vii) that concern any liability
of a "multi-employer plan" (as defined in Section 4001(a)(3) of ERISA) under
Title IV of ERISA; (viii) that concern any notice any benefit continuation
requirements of COBRA or (ix) as to which any suit, proceeding or claim is
brought against Corporation or any of its ERISA Affiliates, or any Plan which
includes current employees or former employees of Corporation or any of its
ERISA Affiliates by reason of their employment by Corporation or any of its
ERISA Affiliates, or any fiduciary or former fiduciary of any such plan,
provided, however, that the obligation of Corporation and ERISA Affiliates to
indemnify Buyer and/or Parent pursuant to the provisions of this Paragraph 12
shall not apply to or include any loss, claim, damage liability, cost or expense
which is based upon or arose out of an act, omission, event, condition or
circumstance of Buyer, Parent or their respective affiliates which occurred
after the date hereof.

(iv)  any Taxes of Corporation or any Subsidiary with respect to any Tax year or
portion thereof ending on or before the Closing Date (or for any Tax year
beginning before and ending after the Closing Date to the extent allocable (as
determined in a manner consistent with subparagraph 14(a)(ii) hereof to the
portion of such period beginning before and ending on the Closing Date), to the
extent such Taxes are not reflected in the reserve for Tax liability (rather
than any reserve for deferred Taxes established to reflect timing differences
between book and Tax income) shown on the Net Worth Statement as determined to
be final, conclusive and binding on all parties pursuant to subparagraph 2(b)
hereof;

(v)   any unpaid Taxes of any person (other than that of Corporation or any
Subsidiary under Regulation Section 1.1502-6 (or any similar provision of state,

(vii)     any and all actions, suits, proceedings, demands, assessments,
penalties, liabilities, judgments, reasonable attorneys' fees, costs, expenses
and interest incident to any of the foregoing (the "Deficiency Costs").

(c)  Procedures for Establishment of Deficiencies. In the event that any claim
     --------------------------------------------
shall be asserted against Buyer, Parent, or Corporation which, if sustained,
would result in a Deficiency, Buyer or Parent, as the case may be, within a
reasonable time after learning of such claim, shall notify the Indemnitor of
such claim, and shall extend to the Indemnitor a reasonable opportunity to
defend against such claim, at the Indemnitor's sole expense and through legal
counsel reasonably satisfactory to Buyer or Parent, as the case may be, and
utilizing any insurance coverage which may be available with respect to such
claim and/or costs and expenses of the defense thereof; provided that the
Indemnitor proceeds in good faith, expeditiously and diligently. Buyer or
Parent, as the case may be, shall, at its option and expense, have the right to
participate in any defense undertaken by the Indemnitor with legal counsel of
its own selection. If the Indemnitor, in the reasonable judgment of Buyer or
Parent, as the case may be, after written notice to Indemnitor and reasonable
opportunity to cure has failed to prosecute such defense in good faith in an
expeditious and diligent manner, Buyer or Parent, as the case may be, shall have
the right to defend and/or settle such claim on behalf of the Indemnitor at the
Indemnitor's expense utilizing any insurance coverage which may be available
with respect to such claim and/or costs and expenses of the defense thereof. No
settlement or compromise of any claim which may result in a Deficiency may be
made by the Indemnitor without the prior written consent of Buyer or Parent, as
the case may be, unless the proposed settlement is solely a monetary settlement
and prior to such settlement or compromise Stockholders acknowledge in
<PAGE>

writing their obligation to pay in full the amount of the settlement and all
associated expenses, subject to the limitations set forth in this Paragraph 12,
and Buyer or Parent, as the case may be, is furnished with a full release from
the claimant in form and substance reasonably satisfactory to Buyer or Parent,
as the case may be. In connection with the defense against the claim, Buyer or
Parent, as the case may be, shall make reasonably available (and shall cause
Corporation to make reasonably available) to Stockholders and their accountants,
attorneys, agents, and representatives during normal business hours the books
and records (including any accountant's work papers), contracts, agreements,
documents, instruments and other information relating to the claim, upon
reasonable advance notice to Buyer or Parent, as the case may be, and shall
otherwise cooperate in good faith with Stockholders with respect to the defense
against the claim, including in connection with compliance with any subpoena,
request for documents, or similar request for discovery; provided, however, that
Stockholders shall schedule such access or requests through an authorized
representative of Buyer or Parent, as the case may be, and in such a way as to
avoid material disruption of the normal business operations of Corporation.

(d)       Payment of Deficiencies.
          -----------------------
(i)            If, within a period of 15 business days after the giving of
written notice by Buyer or Parent, as applicable, of a Deficiency in the manner
required under subparagraph 12(c), Indemnitor shall not give written notice to
Buyer or Parent, as the case may be, announcing its intention to contest such
assertion of Buyer or Parent, as the case may be, (such notice by the Indemnitor
being hereinafter called the "Contest Notice"), such assertion of Buyer or
Parent, as the case may be, shall be deemed accepted and the amount of the
Deficiency shall be deemed established. In the event, however, that a Contest
Notice is given to Buyer or Parent, as applicable, within said 15 day period,
then the contested assertion of a Deficiency shall be settled by arbitration to
be held in Wilmington, Delaware in accordance with the commercial arbitration
rules of the American Arbitration Association then obtaining. The determination
of the
<PAGE>

arbitrator(s) shall be delivered in writing to Stockholders and Buyer or Parent,
as the case may be, and shall be final, binding and conclusive upon all of the
parties hereto, and the amount of the Deficiency, if any, determined to exist by
the arbitrator(s) shall be deemed established.

(ii)           Buyer, Parent and Stockholders may agree in writing, at any time,
as to the existence and amount of a Deficiency, and, upon the execution of such
agreement, such Deficiency shall be deemed established. Any amounts required to
be paid with respect to an established Deficiency but not paid by the Indemnitor
within 10 business days after such Deficiency is established (the "Deficiency
Payment Date") shall bear interest from the Deficiency Payment Date until the
date paid at an annual rate equal to the rate of interest published as the
"Prime Rate" in The Wall Street Journal on the Deficiency Payment Date plus 3%.

(e)       Limitations. With the exception of (i) any Deficiencies resulting from
          -----------
any misrepresentation, breach of representation or warranty, or any non-
fulfillment of any representation, warranty, covenant or agreement on the part
of Stockholders contained in Paragraph 4 herein, (ii) any Deficiencies resulting
from a Knowing Misrepresentation on the part of Stockholders or (iii) any
Deficiencies resulting from a breach of the representation contained in
subparagraph 5(y), with respect to which there shall be no limitations, (A)
there shall be no liability for any Deficiency unless and until the aggregate of
all Deficiencies incurred by Buyer Indemnified Parties exceeds $100,000, in
which event there shall be liability for Deficiencies only to the extent such
Deficiencies exceed $50,000, and (B) the maximum aggregate amount of
Deficiencies against which the Buyer Indemnified Parties shall be entitled to be
indemnified under this Paragraph 12 with respect to all claims hereunder shall
be $3,000,000. Buyer or Parent shall not be entitled to be reimbursed by the
Stockholders for any asserted Deficiency unless (x) Buyer has determined in good
faith or, if Buyer's determination is challenged by Stockholders, Buyer's
regularly engaged independent auditors shall have determined in good faith, that
the Deficiency is neither a direct cost attributable to an open contract with
the U.S. government or, in
<PAGE>

the case of a Deficiency Cost, an indirect cost reimbursable by the U.S.
government for the year in which such cost was incurred, and therefore would be
deemed an Unallowable Cost, or (y) Buyer has asked for reimbursement for such
direct or indirect cost in the year in which such cost is incurred, and such
cost has been found to be an Unallowable Cost or has not actually been
reimbursed by the U.S. government within 24 months of the cost having been
incurred. Notwithstanding the foregoing, after such 24-month period, (xx)
Stockholders shall be liable and shall promptly pay Buyer for any reimbursed
costs that are subsequently disallowed upon audit or review, and (yy) Buyer
shall promptly return to Stockholders any costs paid by Stockholders to Buyer
hereunder if subsequently allowed and reimbursed by the U.S. government. The
rights of indemnification provided for in this Paragraph 12 shall be the sole
and exclusive remedy of the Buyer Indemnified Parties with respect to any
Deficiencies, Deficiency Costs, and any other claims by and of the Buyer
Indemnified Parties against Stockholders or either of them arising out of or
relating to this Agreement and/or the transactions contemplated by this
Agreement.

13.  The Indemnification of Stockholders.
     -----------------------------------

(a)       Basic Provision. Buyer and Parent (in this Paragraph 13 sometimes
          ---------------
referred to as the "Indemnitor") hereby indemnifies, defends and agrees to hold
harmless Stockholders, each of their respective successors, assigns, agents and
representatives (in this Paragraph 13 sometimes referred to collectively as the
"Stockholder Indemnified Parties"), (each of whom shall be a third party
beneficiary hereof) from, against and in respect of the amount of any and all
Buyer Deficiencies, as the case may be (as hereinafter defined).

(b)       Definition of "Buyer Deficiencies". As used in this Paragraph 13,
          ---------------------------------
"Buyer Deficiencies" means:

(i)       any and all loss or damage resulting from any misrepresentation,
breach of warranty, or any non-fulfillment of any warranty, representation,
covenant or agreement on the part of Buyer or Parent contained herein; and
<PAGE>

(ii)      any and all acts, suits, proceedings, demands, assessments, judgments,
reasonable attorneys' fees, costs and expenses incident to any of the foregoing.

(c)       Procedures for Establishment of Buyer Deficiencies. In the event that
          --------------------------------------------------
any claim shall be asserted by any party against an Indemnitee which, if
sustained, would result in a Buyer Deficiency, Stockholders, within a reasonable
time after learning of such claim, shall notify the applicable Indemnitor of
such claim, and shall extend to the Indemnitor a reasonable opportunity to
defend against such claim, at the Indemnitor's sole expense and through legal
counsel reasonably acceptable to Stockholders, and utilizing any insurance
coverage which may be available with respect to such claim and/or costs and
expenses of the defense thereof provided that the Indemnitor proceeds in good
faith, expeditiously and diligently. Stockholders shall, at their option and
expense, have the right to participate in any defense undertaken by the
Indemnitor with legal counsel of their own selection. If the Indemnitor, in the
reasonable judgment of Stockholders, after written notice to Indemnitor and
reasonable opportunity to cure has failed to prosecute such defense in good
faith in an expeditions and diligent manner, Stockholders shall have the right
to defend and/or settle such claim on behalf of the Indemnitor at the
Indemnitor's expense. No settlement or compromise of any claim which may result
in a Buyer Deficiency may be made by the Indemnitor without the prior written
consent of Stockholders, unless the proposed settlement is solely a monetary
settlement and prior to such settlement or compromise Buyer or Parent, as the
case may be, acknowledges in writing its obligation to pay in full the amount of
the settlement and all associated expenses, subject to the limitations set forth
in this Paragraph 13, and Stockholders are furnished with a full release from
the claimant in form and substance reasonably satisfactory to Stockholders.

(d)       Payment of Deficiencies.
          -----------------------

(i)            If, within a period of 15 business days after the giving of
written notice by Stockholders of a Deficiency in the manner requested under
subparagraph 13(c), Indemnitor shall
<PAGE>

not give written notice to Stockholders announcing its intention to contest such
assertion of Stockholders (such notice by the Indemnitor being hereinafter
called the "Contest Notice"), such assertion of the Indemnitee shall be deemed
accepted and the amount of the Buyer Deficiency shall be deemed established. In
the event, however, that a Contest Notice is given to Stockholders within such
15 day period, then the contested assertion of a Buyer Deficiency shall be
settled by arbitration to be held in Wilmington, Delaware in accordance with the
commercial arbitration rules of the American Arbitration Association then
obtaining. The determination of the arbitrator(s) shall be delivered in writing
to Stockholders and Buyer or Parent, as the case may be, and shall be final,
binding and conclusive upon all of the parties hereto, and the amount of the
Deficiency, if any, determined to exist by the arbitrator(s) shall be deemed
established.

(ii)      Buyer, Parent and Stockholders may agree in writing, at any time, as
to the existence and amount of a Deficiency, and, upon the execution of such
agreement, such Deficiency shall be deemed established. Any amounts required to
be paid with respect to an established Buyer Deficiency but not paid by the
Indemnitor within 10 business days after such Buyer Deficiency is established
(the "Deficiency Payment Date") shall bear interest from the Deficiency Payment
Date until the date paid at an annual rate equal to the rate of interest
published as the "Prime Rate" in The Wall Street Journal on the Deficiency
Payment Date plus 3%.

(e)       Limitations. With the exception of any obligation of Buyer or Parent
          -----------
to pay the Purchase Price, with respect to which there shall be no limitations,
(A) there shall be no liability for any Buyer Deficiency unless and until the
aggregate of all Buyer Deficiencies incurred by the Stockholder Indemnified
Parties exceeds $100,000, in which event there shall be liability for Buyer
Deficiencies only to the extent such Buyer Deficiencies exceed $50,000, and (B)
the maximum aggregate amount of Buyer Deficiencies against with the Stockholder
Indemnified Parties shall be entitled to be indemnified under this Paragraph 13
with respect to all claims
<PAGE>

hereunder shall be the amount of the Purchase Price less any cash paid in
consideration of the Purchase Price.

14.  Tax Covenants Relating to Corporation.
     -------------------------------------

(a)       The following provisions shall govern the allocation of responsibility
as between Buyer and Stockholders for certain Tax matters following the Closing
Date:

               (i) Stockholders shall timely prepare or cause to be prepared and
file or cause to be filed all Returns for Corporation and each of the
Subsidiaries for all tax periods ending on or prior to the Closing Date which
are to be filed after the Closing Date. Copies of all such returns shall be made
available to Buyer at least 10 days prior to the date on which they are to be
filed. If any such Return indicates that Corporation or any Subsidiary has
incurred any liability for Tax in excess of the amount of such Taxes which are
included in the reserve for Tax liability (rather than any reserve for deferred
Taxes established to reflect timing differences between book and Tax income) on
the Net Worth Statement, Stockholders shall pay such excess to Buyer within 15
days after receipt by Stockholders of a request for payment by Buyer.

               (ii) Buyer at its expense shall timely prepare or cause to be
prepared and file or cause to be filed all Returns for Corporation and each
Subsidiary for Tax periods which begin before the Closing Date and end after the
Closing Date and shall pay the Taxes due with respect to such Returns. Copies of
all such returns shall be made available to Stockholders at least 10 days prior
to the date on which they are to be filed. During such 10 day period,
Stockholders may provide to Buyer such comments or proposed changes as they deem
appropriate. Stockholders shall pay to Buyer the excess of (x) a pro rated
amount (calculated as described in subparagraph 14(a)(ii)(A) or (B)) of the
Taxes of each of Corporation and the Subsidiaries for any such period over (y)
the amount of the Taxes paid by each of Corporation and the Subsidiaries on or
prior to the Closing Date with respect to such period and the amount of such
Taxes which are included in the reserve for Tax liability (rather than any
reserve for Tax
<PAGE>

liability to reflect timing differences between book and Tax items) on the Net
Worth Statement as determined to be final, conclusive and binding on all parties
pursuant to subparagraph 2(b) hereof. Such payment by Stockholders to Buyer
shall be made within 15 days after receipt by Stockholders of a request for
payment from Buyer which includes the Return, if available, or any other
document used to calculate the pro rated amount of the Taxes.

          (A) In the case of all Taxes imposed upon or measured by property or
capital, the pro rated amount shall be based upon the number of days in the
period up to and including the Closing Date divided by the total number of days
in the Tax period.

          (B) In the case of all Taxes other than those imposed upon or measured
by property or capital, including but not limited to net income, gross receipts
taxes, sales and use taxes, and payroll taxes, the pro rated amount shall be
based upon the transactions occurring on or before the Closing Date.

(b)       All tax sharing agreements or similar agreements with respect to or
involving Corporation shall be terminated as of the Closing Date and, after the
Closing Date, Corporation shall not be bound thereby or have any liability
thereunder.

(c)       All transfer (including real estate), documentary, sales, use, stamp,
registration and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement shall be paid by
Stockholders when due, and Stockholders shall, at their own expense, file all
necessary Returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration and other Taxes and fees, and, if
required by applicable law, Buyer will, and will cause its affiliates to, join
in the execution of any such Returns and other documentation.

(d)       Buyer and Stockholders shall cooperate fully (and cause Corporation
and the Subsidiaries to cooperate fully), as and to the extent reasonably
requested by the other party, in connection with the preparation, execution and
filing of Returns pursuant to this Agreement and
<PAGE>

any audit, contest, litigation or other proceeding with respect to Taxes. Such
cooperation shall include retention and (upon the other party's request) the
provision of records and information which are reasonably relevant to any such
audit, litigation or other proceeding and making themselves, in the case of
Stockholders, and employees, in the case of Buyer, available on a mutually
convenient basis to provide additional information and explanation of any
material. Stockholders agree (i) to retain all books and records with respect to
Tax matters pertinent to Corporation relating to any Tax period beginning before
the Closing Date until the expiration of the stature of limitations (and, to the
extent notified by Buyer, any extensions thereof) of the respective taxable
periods (unless such items were transferred pursuant to this Agreement in which
case Buyer agrees to be bound by the record retention requirements and notice
provisions of this subparagraph), and to abide by all record retention
agreements entered into with any Tax authority, and (ii) to give Buyer
reasonable written notice prior to transferring, destroying or discarding any
such books and records and, if Buyer so requests, Stockholders shall allow Buyer
to take possession of such books and records.

(e)       Buyer and Stockholders agree, upon request, to use their best effort
to obtain any certificate or other document from any governmental authority or
any other person as may be necessary to mitigate, reduce or eliminate any Tax
that could be imposed (including, but not limited to, with respect to the
transactions contemplated hereby).

(f)       Buyer and Stockholders agree, upon request, to provide the other party
with all information that either party may be required to report pursuant to
Code Section 6043 and all Regulations promulgated thereunder.

(g)       Buyer shall promptly notify Stockholders in writing of the
commencement of any claim, audit, examination, or other proposed change or
adjustment by any tax authority concerning any Tax or other similar claim or
assessment for which Stockholders may be responsible (a "Tax Claim"); provided,
however, that failure to give such notice shall not relieve
<PAGE>

any party from its obligation to indemnify with respect to any such Tax Claim
except to the extent of actual prejudice. Stockholders shall have the right to
employ counsel of their choice at their expense and to participate with Buyer,
Corporation and any Subsidiaries in resolving any dispute of Taxes with respect
to Tax periods beginning before the Closing Date through the appropriate
administrative offices and in the courts, and shall have primary responsibility
for the conduct of any such proceedings relating solely to periods ending on or
before the Closing Date. Stockholders and Buyer shall be liable on a pro rated
basis (determined as in subparagraph 14(a)(ii) above) for all expenses, costs,
fees (including attorney's and accountant's fees) incurred by Buyer or
Corporation after the Closing Date in connection with the resolution of all Tax
disputes and Tax audits with respect to any tax period which includes the
Closing Date but which does not end on or before the Closing Date. Stockholders
shall make payment of its share of such costs, expenses and fees within 15 days
after receipt of notice of such expenses from Buyer, except that Buyer or Parent
shall not be entitled to be reimbursed by Stockholders for any such costs,
expenses and fees unless (x) Buyer has determined in good faith or, if Buyer's
determination is challenged by Stockholders, Buyer's regularly engaged
independent auditors shall have determined in good faith, that such costs,
expenses and fees are neither a direct cost, expense or fee attributable to an
open contract with the U.S. government or an indirect cost, expense or fee
reimbursable by the U.S. government for the year in which such cost, expense or
fee was incurred, and therefore would be deemed an Unallowable Cost, or (y)
Buyer has asked for reimbursement for such costs, expenses and fees in the year
in which such costs, expenses and fees are incurred, and such costs, expenses
and fees have been found to be Unallowable Costs or have not actually been
reimbursed by the U.S. government within 24 months of the costs, expenses and
fees having been incurred. Notwithstanding the foregoing, after such 24-month
period, (xx) Stockholders shall be liable and shall promptly pay Buyer for any
such reimbursed costs, expenses and fees that are subsequently disallowed upon
audit or review, and (yy) Buyer

<PAGE>

     shall promptly return to Stockholders the amount of any costs, expenses and
     fees paid by Stockholders to Buyer hereunder if subsequently allowed and
     reimbursed by the U.S. government.

     (h)    Except as otherwise provided in this Paragraph 14, the party
     preparing a Return or required to prepare a Return shall control resolution
     of any audit or investigation, and any proceedings with taxing authorities,
     with respect to the Tax liability relating to such Return. However, the
     party entitled to control any such audit, investigation or proceeding may,
     at its sole option, extend to the party with economic liability for any
     Taxes at issue therein the opportunity to assume the defense of the matter.

     (i)    The parties agree that each will join in making an election under
     Section 338(h)(10) of the Code with respect to the purchase by Buyer of all
     of the Shares as contemplated by this Agreement. The parties acknowledge
     that pursuant to such election, the Corporation will be treated for federal
     income tax purposes (and under state and local income tax laws, to the
     extent permitted) as having sold its assets in the manner set forth in
     Treasury Regulation Section 1.338(h)(10)-1. The parties acknowledge that
     (i) for federal income tax purposes, the Corporation shall be deemed to
     have sold all of its assets at the date hereof and distributed the proceeds
     received from the Buyer in liquidation of the Corporation, (ii) the
     Corporation's final "S" corporation tax year will end at the close of
     business on the date hereof, and (iii) as of the opening of business on the
     day after the date hereof, Corporation will be deemed to be a new
     corporation which purchased all of its assets. The parties shall report all
     transactions and make all filings with the Internal Revenue Service (and
     state and local income tax authorities, to the extent permitted) consistent
     with this election. The election under Section 338(h)(10) of the Code shall
     be made on Form 8023 (revised September 1997), shall be prepared and filed
     by the Buyer and four copies of Form 8023 shall on the date hereof be
     signed by each of the Stockholders. With respect to the Forms 8023 to be
     signed on the date hereof, the Buyer shall fill in as much of the
     information

<PAGE>

     required to be put on the Form and in attachments thereto with respect to
     the Corporation, Buyer and Stockholders as is reasonably ascertainable by
     the date hereof. The balance of the information required on or with the
     Forms shall be filled in and added as soon after the date hereof as
     possible. Stockholders agree to provide Buyer with the information which
     Buyer needs to include on the Form which relates to Stockholders and the
     Corporation. Buyer shall file a completed and fully executed Form 8023 with
     the appropriate District Director for the Internal Revenue district as is
     provided in the instructions to the Form 8023. Buyer shall provide to
     Stockholders copies of the Form 8023 that is filed with the District
     Director as soon as it is completed and ready for filing. Each Stockholder
     agrees to timely file the copies of the Form 8023 provided to it by the
     Buyer in the manner called for in the instructions to the Form 8023.

     15. Further Assurances; Registration Rights.
         ---------------------------------------

             (a) Buyer and Stockholders agree to execute and deliver all such
     other instruments and take all such other action as any party may
     reasonably request from time to time, after the date hereof and without
     payment of further consideration, in order to effectuate the transactions
     provided for herein. The parties shall cooperate fully with each other and
     with their respective counsel and accountants in connection with any steps
     required to be taken as part of their respective obligations under this
     Agreement, including, without limitation, the preparation of financial
     statements and Tax Returns. Buyer agrees to cause Corporation to retain and
     make available to Stockholders, as reasonably requested and during normal
     business hours, any and all books and records of Corporation concerning
     Taxes for each and every Tax period ending on or before or including the
     Closing Date for a period of at least six (6) years following the end of
     each such Tax period and any and all books and records of Corporation
     concerning each of Corporation's contracts for a period of four (4) years
     after the date of the "End of Contract" of such contract, which shall be
     the latter of the date of Contract Closeout or the date of completion of
     performance thereunder.

<PAGE>

               (b) Parent agrees to grant Stockholders registration rights with
     respect to the Common Shares which are pari-passu and on the same terms and
     conditions as any registration rights to be granted to any officer of
     Parent or any of its subsidiaries, none of which are in force as of the
     date hereof.

     16.    Consent to Jurisdiction, Service of Process, Appointment of Agent.
            -----------------------------------------------------------------
     (a)       Each Stockholder hereby irrevocably submits to the jurisdiction
     of any Delaware State or Federal court sitting in the City of Wilmington
     over any suit, action or proceeding arising out of or relating to this
     Agreement. Stockholders hereby irrevocably waive, to the fullest extent
     permitted by applicable law, any objection which they or any of them may
     now have or hereafter have to the laying of the venue of any such suit,
     action or proceeding brought in such court and any claim that any such
     suit, action or proceeding brought in such a court has been brought in an
     inconvenient forum. Buyer, Parent and each Stockholder agrees that, to the
     fullest extent permitted by applicable law, a final judgment in any such
     suit, action, or proceeding brought in such a court shall be conclusive and
     binding upon Buyer, Parent and Stockholders, and may be enforced in any
     courts of the jurisdiction of which Buyer, Parent or Stockholders, as the
     case may be, is or are or may be subject by a suit upon such judgment,
     provided that service or process is effected upon Buyer, Parent or
     Stockholders, as the case may be, in one of the manners specified in
     subparagraph (b) below or as otherwise permitted by applicable law.

     (b)       Buyer, Parent and each Stockholder hereby consents to process
     being served in any suit, action or proceeding of the nature referred to in
     subparagraph (a) above by the mailing of a copy thereof by registered or
     certified first-class air mail, postage prepaid, return receipt requested,
     to Buyer, Parent or such Stockholder, as the case may be, at such parties
     address set forth in subparagraph 17(c) hereof.

     (c)       Nothing in this Paragraph 16 shall affect the right of Buyer,
     Parent or Stockholders to serve process in any manner permitted by law or
     affect the right of Buyer, Parent or

<PAGE>

     Stockholders to bring proceedings against Buyer, Parent or Stockholders, or
     either of them, as the case may be, in the courts of any jurisdiction or
     jurisdictions.

     2.  Miscellaneous.
         -------------

     (a)       Indulgences, Etc. Neither the failure nor any delay on the part
               ----------------
     of any party to exercise any right, remedy, power or privilege under this

     partial exercise of any right, remedy, power or privilege preclude any
     other or further exercise of the same or of any other right, remedy, power

     with respect to any occurrence be construed as a waiver of such right,

     asserted to have granted such waiver.

     Delaware, notwithstanding any conflict-of-laws doctrines of such state or
     other jurisdiction to the contrary, and without the aid of any canon,
     custom or rule of law requiring construction against the draftsman.

                             EMPLOYMENT AGREEMENT
                             --------------------

     THIS EMPLOYMENT AGREEMENT (the "Agreement") is made as of this 31st day of
October, 2000, by and between Social and Health Services, Ltd., a Maryland
corporation (the "Company"), Macro International Inc., a Delaware corporation
("Macro") and Lewis D. Eigen (the "Executive").

                             W I T N E S S E T H:
                             - - - - - - - - - -

     WHEREAS, the Company believes that it would benefit from the application of
the Executive's particular and unique skill, experience and background, and
wishes to employ the Executive as an executive of the Company; and

     WHEREAS, the parties desire by this Agreement to set forth the terms and
conditions of the employment relationship between the Company and the Executive.

     NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
in this Agreement, the Company and the Executive agree as follows:

1.   Employment and Duties.
     ---------------------

(a)       The Company hereby employs the Executive as an executive on the terms
and conditions provided in this Agreement, and the Executive agrees to accept
such employment subject to the terms and conditions of this Agreement. The
Executive shall serve in a senior executive capacity and shall have such
executive duties and responsibilities as shall from time to time be determined
by the Board of Directors of the Company (the "Board") or the Chief Executive
Officer of Macro (the "CEO").

(b)       The Executive agrees to devote his best efforts and substantially all
of his time, attention, energy and skill to performing his duties hereunder.
Provided that such activities shall not violate any provision of this Agreement
or the Agreement Not To Compete of even date herewith among the Executive, the
Company, Macro and Opinion Research Corporation (the "Non-Compete Agreement") or
materially interfere with the performance of his duties hereunder,
<PAGE>

nothing herein shall prohibit the Executive (i) from engaging in charitable,
civic, fraternal, or trade group activities, (ii) from writing academic, trade
or mainstream papers or other publishable books, or (iii) from investing his
assets in other entities or business ventures.

(c)       Without the Company's prior consent, the Executive shall not obtain
goods or services or otherwise deal on behalf of the Company with any business
or entity in which the Executive or a member of his family has a financial
interest or from which the Executive or a member of his immediate family may
derive a financial benefit as a result of such transaction, except that this
prohibition shall not apply to any public company in which the Executive or a
member of his family owns less than three percent of the outstanding stock.

2.   Term.  The term of this Agreement shall commence on the date hereof
     ----
and shall terminate on the third anniversary of the date hereof (the "Term"),
unless extended by mutual agreement of the parties or earlier terminated in
accordance with the terms of this Agreement.

3.   Compensation.
     ------------

(a)       Base Compensation.  As compensation for performing the services
          -----------------
required by this Agreement, the Company shall pay to the Executive an annual
salary ("Annual Salary") of One Hundred Sixty-Two Thousand Five Hundred Dollars
($162,500), payable in equal installments pursuant to the Company's customary
payroll procedures in effect for its executive personnel at the time of payment,
but in no event less frequently than monthly, subject to withholding for
applicable federal, state, and local taxes. The Executive's Annual Salary shall
not be reduced during the term of this Agreement. The Executive's compensation
shall be reviewed annually by the Board or the CEO, as applicable, it being
understood that there shall be no obligation to increase the Executive's
compensation as a result of such review.

(b)       Bonus Compensation. In addition to Annual Salary, commencing with the
          ------------------
calendar year 2001, the Executive may receive bonus compensation to be
determined by the Board or the CEO, as applicable, in their or its absolute
discretion based on an annual review of
<PAGE>

the executive's performance. The Executive shall be entitled to a minimum bonus
for the 2001 calendar year in the amount of Thirty-Seven Thousand Five Hundred
Dollars ($37,500).

4.   Executive Benefits.  During the term of this Agreement the Executive
     ------------------
and his eligible dependents shall have the right to participate in any
retirement plans (qualified and non-qualified), pension plans, life, health and
disability insurance, cafeteria plans, or other benefit plan or program that has
been or is hereafter adopted by the Company (or in which the Company
participates), according to the terms of such plan or program.  Except in the
event of a termination of the Executive's employment by the Company for Cause
(as hereinafter defined), the Company shall use reasonable efforts to continue
to include the Executive in the Company's group health insurance plan after
termination of the Executive's employment with the Company and at the prevailing
COBRA rates, provided that, whether at COBRA rates or otherwise, the Executive
shall pay the Company an amount equal to the difference, if any, between the
cost to the Company of providing health insurance to its employees and the
Executive and the cost of providing such health insurance coverage without the
Executive.

5.   Vacation and Leaves of Absence.  The Executive shall be entitled to 20
     ------------------------------
vacation days during each calendar year.  Vacation will accrue, and unused
vacation days may be carried over to subsequent years, in accordance with
Macro's vacation policy in effect on the date of this Agreement.  Upon any
termination of this Agreement for any reason whatsoever, accrued and unused
vacation for the year in which this Agreement terminates will be paid to the
Executive within 10 days of such termination based on his Annual Salary in
effect on the date of such termination.  In addition, the Executive may be
granted leaves of absence with or without pay for such reasons as the Board in
its sole and absolute discretion may determine, and shall be entitled to the
same sick leave and holidays provided to other senior executives of the Company.
<PAGE>

6.   Expenses.  The Executive shall be promptly reimbursed against
     --------
presentation of vouchers or receipts for all reasonable and necessary expenses
incurred by him in connection with the performance of business-related duties.

7.   Termination.
     -----------

(a)       Termination by the Company For Cause.  The Company may terminate this
          ------------------------------------
Agreement prior to its expiration date for "Cause". In such event, the Executive
shall be paid for his services hereunder only his Annual Salary up to the
effective date of such termination. For purposes of this Section 7, Cause shall
mean (i) an act of dishonesty by the Executive constituting a felony or
resulting or intended to result in gain to, or personal enrichment of, the
Executive at the Company's expense, (ii) the engaging by the Executive in
misconduct which is demonstrably injurious to the Company, (iii) the refusal of
the Executive substantially to perform his duties hereunder, (iv) the violation
of any reasonable express direction of the Board or of any reasonable rule,
regulation, policy or plan established by the Company from time to time which
governs the Executive in the performance of his work, (v) the use by the
Executive of any illegal substance, or the use by the Executive of alcohol or
any controlled substance to an extent that it interferes with the performance of
the Executive's duties under this Agreement, and (vi) the substantial breach by
the Executive of his obligations in this Agreement or in the Non-Compete
Agreement; provided, however, that, with respect to Sections 7(a)(iii), (iv) and
(vi), such refusals, violations, and/or breaches remain uncured for a period of
15 days after written notice thereof is received by the Executive (the "Notice
and Cure Period"); provided, further, that no second Notice and Cure Period
shall be required with respect to a second violation of any one of the
aforementioned sections, regardless of whether the first violation was cured.

(b)       Termination by the Company Without Cause.  The Company may
          ----------------------------------------
terminate this agreement prior to its expiration without Cause. In such event,
the Executive shall be entitled to the continuation of his Annual Salary and
health insurance coverage during the lesser of (i) a
<PAGE>

period of one year from the date of termination, or (ii) a period equal to the
remainder of the Term. Such annual salary shall be payable in equal installments
pursuant to the Company's customary payroll procedures in effect for its
executive personnel at the time of payment.

(c)       Termination by the Executive.  The Executive may terminate this
          ----------------------------
Agreement upon 30 days' written notice to the Company (during which period the
Executive shall, if requested in writing by the Company, continue to perform his
duties as specified under this Agreement). In such event, the Executive shall be
paid only his Annual Salary for his services hereunder up to the effective date
of such termination. In addition, the Executive may terminate this Agreement for
"Good Cause." For purposes of this Section 7(c), Good Cause shall mean the
failure of the Company to pay to the Executive his Annual Salary or Bonus
Compensation (except in the event of the dispute as to the calculation of such
Bonus Compensation), provided that such failure shall remain uncured for a
period of 15 days after written notice thereof is received by the Company. In
the event this Agreement is terminated for Good Cause by the Executive, the
Company shall be deemed in breach of this Agreement and the Executive, in
addition to the Executive's rights under the Agreement Not To Compete, shall be
entitled to such damages with respect thereto as to which he may be entitled at
law or in equity with respect thereto.

(d)       Disability.  The Company may terminate this Agreement due to the
          ----------
Executive's illness, physical or mental disability, or other incapacity, in
accordance with the Company's disability practices and policies in effect from
time to time; provided, however, that no such termination may occur unless and
until the Executive has not performed such Executive's duties under this
Agreement due to such illness, disability or other incapacity for at least [six]
months. However, prior to such a termination of this Agreement, the Executive
shall not be entitled to his Annual Salary during any period during which the
Executive is receiving sick pay or short-term
<PAGE>

disability payments from the Company, or long-term disability insurance payments
under the Company's long term disability insurance plan.

(e)       Death.  This Agreement shall terminate on the date of the Executive's
          -----
death. In such event the Executive's estate shall be paid his Annual Salary for
the remainder of the month in which such termination occurs.

8.   Prior Agreements, Conflicts of Interest.  The Executive represents to the
     ---------------------------------------
Company (a) that there are no restrictions, agreements or understandings,
oral or written, to which the Executive is a party or by which the Executive is
bound that prevent or make unlawful the Executive's execution or performance of
this Agreement; (b) none of the information supplied by the Executive to the
Company or any representative of the Company in connection with the Executive's
employment by the Company misstated a material fact or omitted information
necessary to make the information supplied not materially misleading; and (c)
the Executive does not have any business or other relationship that creates a
conflict between the interests of the Executive and the Company.

9.   Company Property.  All materials or data of any kind furnished to the
     ----------------
Executive by the Company, or developed by the Executive on behalf of the
Company, or at the direction of the Company, or for the use of the Company, or
otherwise in connection with the Executive's employment hereunder, are and shall
remain the sole and confidential property of the Company, whichever applicable;
if the Company requests the return of such materials at any time during, at or
after the termination of the Executive's employment, the Executive shall
immediately deliver the same to the Company.

10.  Macro as Guarantor.  Macro hereby unconditionally guarantees the
     ------------------
obligations of the Company to the Executive.
<PAGE>

11.  Miscellaneous.
     -------------

(a)       Integration; Amendment.  This Agreement, together with the Non-Compete
          ----------------------
Agreement, constitutes the entire agreement between the parties hereto with
respect to the employment matters set forth herein. No amendments or additions
to this Agreement shall be binding unless in writing and signed by all parties
hereto.

(b)       Assignability.  The Company may assign its rights and obligations
          -------------
under this Agreement to Macro or an affiliate of Macro, in which event Macro or
such affiliate shall be the Executive's employee.

(c)       Severability.  If any part of this Agreement is contrary to,
          ------------
prohibited by, or deemed invalid under applicable law or regulations, such
provision shall be inapplicable and deemed omitted to the extent so contrary,
prohibited, or invalid, but the remainder of this Agreement shall not be invalid
and shall be given full force and effect so far as possible.

(d)       Waivers.  The failure or delay of any party at any time to require
          -------
performance by the other party of any provision of this Agreement, even if
known, shall not affect the right of such party to require performance of that
provision or to exercise any right, power, or remedy hereunder, and any waiver
by any party of any breach of any provision of this Agreement shall not be
construed as a waiver of any continuing or succeeding breach of such provision,
a waiver of the provision itself, or a waiver of any right, power, or remedy
under this Agreement. No notice to or demand on any party in any case shall, of
itself, entitle such party to the other or further notice or demand in similar
or other circumstances.

(e)       Burden and Benefit.  This Agreement shall be binding upon and inure
          ------------------
to the benefit of the parties hereto and their respective successors and
