Item 2. Acquisition or Disposition of Assets.

     On July 24, 1998, OAO Technology  Solutions,  Inc., a Delaware  corporation
(the  "Company"),  announced  by a press  release  that it had  consummated  the
acquisition of all of the outstanding  capital stock (the  "Acquisition") of OAO
Services, Inc., a District of Columbia corporation ("OAO Services"), pursuant to
the Stock  Purchase  Agreement  dated as of July 24, 1998 (the  "Stock  Purchase
Agreement")  among the  Company,  OAO  Services,  OAO  Corporation  ("OAOC") and
William R. Hill  ("Hill," and together  with OAOC,  the  "Stockholders"),  which
Acquisition  was  effective  as of  12:00  a.m.  E.D.T.  on  July 1,  1998  (the
"Effective Time"). Prior to the consummation of the Acquisition (the "Closing"),
OAO Services  was a  majority-owned  subsidiary  of OAOC.  The press  release is
attached hereto as Exhibit 99.1 and incorporated herein by reference.

     Pursuant to the terms of the Stock Purchase  Agreement,  the purchase price
payable by the Company to the  Stockholders  in connection  with the Acquisition
includes (i) cash in the amount of $2,305,000  (the "Cash  Payment")  subject to
downward  adjustment based on a post-closing  audit (the "Audit") of and certain
adjustments  (the  "Purchase  Price  Adjustments")  to be made to OAO  Services'
balance sheet as of the Effective Time relating to the repayment of intercompany
receivables  by  OAOC to OAO  Services  and a cash  contribution  by OAOC to OAO
Services  with  respect to OAO  Services'  net  equity,  (ii) the payment by the
Company to Sanwa Business Credit  Corporation  ("Sanwa") of $4,561,000 to retire
the portion of outstanding debt under a financing  agreement among Sanwa,  OAOC,
OAO  Services  and a  wholly-owned  subsidiary  of  OAOC  (the  "OAOC  Financing
Agreement")  which was secured by the  outstanding  accounts  receivable  of OAO
Services  and  assumed by the  Company in the  Acquisition,  and (iii)  earn-out
payments up to a maximum aggregate amount of $5,000,000, as more fully described
below. A portion of OAOC's share of the Cash Payment in the amount of $1,100,000
was paid by the Company at the Closing directly to Sanwa in partial repayment of
outstanding  borrowings of OAOC under the OAOC Financing Agreement.  The balance
of the Cash Payment has been retained by the Company until the completion of the
Audit and the determination of the Purchase Price  Adjustments  described above,
at which time the remaining balance of the Cash Payment, if any, will be paid to
the Stockholders or credited  against amounts owed by them to the Company.  With
respect to the earn-out payments, the Stock Purchase Agreement provides that the
Company will make additional cash payments to the  Stockholders in amounts equal
to 10% of the  Company's  Pre-Tax  Profit  (as  defined  in the  Stock  Purchase
Agreement) in excess,  if any, of $2,000,000  (which amount is subject to annual
increases  based on increases in the  outstanding  shares of common stock of the
Company),  for the three years  ending  December 31,  1999,  2000 and 2001.  The
aggregate of all earn-out  payments under the Stock Purchase  Agreement will not
exceed  $5,000,000,  and each earn-out payment will be payable by the Company on
the 90th  business  day after the  Company's  receipt of its  audited  financial
statements for the year for which such payment is to be made.

     The consideration payable by the Company for the Acquisition was negotiated
at arms' length among the parties to the Stock Purchase  Agreement.  In deriving
the  consideration,  the Company  considered,  among other things, the financial
condition of OAO Services and its business,  operations and earnings  prospects.
The Company used existing cash balances for the payments at Closing  aggregating
$5,661,000  and expects to use existing  cash for the  remaining  portion of the
Cash Payment, if any.

     Hill is the former Chief  Executive  Officer of the Company and is a member
of the Company's Board of Directors.  Cecile D. Barker ("Barker"),  the Chairman
of the Board of Directors and Chief Executive  Officer of OAOC and the holder of
95% of OAOC's  outstanding  shares of capital stock, is the Vice Chairman of the
Board of Directors of the Company,  owns  approximately  20% of the  outstanding
shares  of common  stock of the  Company  and is the  Company's  second  largest
stockholder.  Lt. Gen.  Emmett Paige,  Jr., the  President  and Chief  Operating
Officer of OAOC, is a member of the Company's Advisory Council Board.

     Pursuant to the terms of an Option Cancellation  Agreement dated as of July
11,   1997  among  the   Company,   Safeguard   Scientifics   (Delaware),   Inc.
("Safeguard"),  OAOC,  OAO Services,  Barker and Hill, the Company and Safeguard
were each to receive from OAOC  one-half of (i) the greater of  $1,000,000 or an
amount  equal to the lesser of  $3,000,000  or three  percent of the total sales
price from the sale of both OAOC and OAO Services which occurred



                                        1

prior to April 8, 2000, (ii) the greater of $1,000,000 or an amount equal to the
lesser of  $2,000,000 or three percent of the total sales price from any sale of
OAOC which  occurred  prior to April 8, 2000 and at such time that OAO  Services
was not an affiliate of OAOC, (iii) the greater of $1,000,000 or an amount equal
to the lesser of  $3,000,000 or three  percent of the market  capitalization  of
OAOC if OAOC  consummated  an initial public  offering of its equity  securities
prior to April 8, 2000 (an "OAOC IPO"),  or (iv) the greater of $1,000,000 or an
amount  equal  to the  lesser  of  $2,000,000  or  two  percent  of  the  market
capitalization of OAOC if OAO Services was no longer affiliated with OAOC at the
time of the OAOC IPO. As a  condition  to and  contemporaneously  with the Stock
Purchase  Agreement,  the parties to the Option  Cancellation  Agreement entered
into an Amendment to Option Cancellation Agreement terminating the rights of the
Company and Safeguard to such payment upon the events described in the preceding
sentence.

     further reduced by the amount of the then  outstanding  Hill Liability (the
     "Hill Liability  Reduction")  (as used herein,  the "Hill Balance" shall be

     Deficiency")  shall be added to the amount of the remaining  Hill Liability

expenses and not repaid by Hill.  Until such time as the Hill Liability has been

amounts payable to Hill under Section 2.2, including any and all amounts payable

additional  cash  payments to the  Shareholders  (the  "Earn-Out  Payments")  in
amounts equal to ten percent (10%) of OAOT's Pre-Tax Profit  (defined  below) in
excess,  if any, of $2,000,000 (the  "Threshold," as adjusted as provided in the
following sentence),  for the three years ended December 31, 1999, 2000 and 2001

Earn-Out  Payments payable for the Earn-Out Period shall not exceed an aggregate
of $5,000,000; and provided,  further, that no Earn-Out Payment shall be payable
if (i)  any  Shareholder  is then  in  breach  in any  material  respect  of any
representation,  warranty,  covenant or agreement  contained  herein or (ii) any

Statement of Financial  Accounting  Standards  No. 121. The  Threshold  shall be
increased  in each year of the  Earn-Out  Period to which the  Earn-Out  Payment
relates by the ratio  obtained by dividing  (A) the total shares of common stock
of OAOT ("OAOT Common Stock")  issued and  outstanding at the end of the year to
which such Earn-Out Payment relates by (B) the total shares of OAOT Common Stock
issued  and  outstanding  as  of  June  30,  1998;  provided  that  such  amount
outstanding  as of June 30, 1998 shall be deemed to include  (y) all shares,  if
any, issued or to be issued in connection  with OAOT's  proposed  acquisition of
Enterprise  Technology  Group and (z) all shares of OAOT Common  Stock  issuable

<PAGE>



in  comparison  to those in effect at the Closing  Time;  and (v) any items that
would be considered  extraordinary items under GAAP; provided,  however, that if
the  business of OAOT as presently  conducted is operated  during any portion of
the Earn-Out  Period as a division of a  corporation  or other  business  entity
other than OAOT,  the  determination  of the Pre-Tax  Profit shall  include such
adjustments  as are deemed  appropriate  so that the Pre-Tax  Profit would be as
close as  possible to the  Pre-Tax  Profit that would have  existed if OAOT were
operated as a separate corporation during that portion of the Earn-Out Period at
issue.

     (c) Subject to the  limitations  set forth in paragraph  (a) above,  on the
90th business day after receipt by OAOT of its audited financial  statements for
the year for which the  Earn-Out  Payment  is being  made,  OAOT  shall pay each
Shareholder,  subject,  in the case of Hill, to any reduction in accordance with
Section 2.5(a) for the Hill Liability, a cash amount equal to such Shareholder's
Proportionate  Interest multiplied by such Earn-Out Payment. OAOT shall make any
such payments to the Shareholders in "same day" funds by wire transfer.

     (d) In the  event  that  a  Shareholder  disputes  the  calculation  of any
Earn-Out Payment under paragraph (a) above (each, an "Earn-Out  Determination"),
such  Shareholder  may dispute  such  Earn-Out  Determination  in the  following
manner.  Within 30 days after OAOT pays the Earn-Out  Payment in accordance with
paragraph  (c) above,  the  Shareholders  jointly  shall give OAOT notice of the
disagreement with the Earn-Out  Determination (the "Dispute  Notice"),  and such
notice  shall  specify in detail the nature of the  disagreement.  During the 20
days after the day on which the Dispute Notice is given,  the  Shareholders  and
OAOT  shall  attempt to resolve  such  dispute.  If they fail to reach a written
agreement regarding the dispute, the Shareholders jointly shall refer the matter
to a firm of  certified  independent  accountants  (the  "Second  Firm") that is
different from the firm that audited OAOT's financial  statements from which the
Earn-Out  Payment at issued was determined  (the "First Firm"),  and request the
Second Firm to also  determine the Pre-Tax  Profit and Threshold of OAOT for the
year of the  Earn-Out  Period at issue  (the  "Second  Earn-Out  Determination")
within the 30 days after such 20-day  period.  OAO shall give OAOT prompt notice
of the results of the Second  Earn-Out  Determination.  During the 20 days after
the day on which OAO gives OAOT notice of the Second Income  Determination,  the
Shareholders and OAOT shall again attempt to resolve such dispute.  If they fail
to reach a written  agreement  regarding the dispute,  the Shareholders and OAOT
shall request the First Firm and the Second Firm together to choose a third firm
of certified  independent  accountants  (the "Third Firm") and request the Third
Firm to also  determine the Pre-Tax Profit and Threshold of OAOT for the year of
the Earn-Out Period at issue (the "Third Earn-Out  Determination") within the 30
days after the request to do so.  OAOT and the  Shareholders  shall  request the
First  Firm and the Second  Firm each to confer  with the Third Firm and to make
available to the Third Firm their  respective work papers regarding the Earn-Out
Determination  and  the  Second  Earn-Out  Determination.   The  Third  Earn-Out
Determination  shall be the final and  binding  Earn-Out  Determination  for the
purposes of determining  whether OAOT shall be obligated to pay the Shareholders
any amount in excess of the Earn-Out  Payment made in accordance  with paragraph
(c) above. The  Shareholders  shall pay the fees and expenses of the Second Firm
with  respect to the Second  Earn-Out  Determination  in  accordance  with their
Proportionate  Interests.  The  Shareholders  and OAOT  shall  pay any  expenses
relating to the engagement of the Third Firm, allocated between the Shareholders
(in accordance with their  Proportionate  Interests as a group) and OAOT so that
the Shareholders' share of such costs shall be in the same proportion that the



                                       11

<PAGE>



aggregate amount of the disputed amounts  submitted to such accounting firm that
are  unsuccessfully  disputed by the Shareholders (as finally determined by such
accounting firm) bears to the total amount of such disputed amounts so submitted
to such accounting firm.

     2.9 Post-Closing Repurchase of Certain Receivables. OAO represents that the
Closing  Balance  Sheet  will  reflect  a  reserve  for  uncollectible  accounts
receivable of at least $175,000 (the "A/R Reserve Amount"). OAO shall repurchase
from the  Company  at their  aggregate  respective  face  amounts,  less the A/R
Reserve Amount,  any accounts  receivable on the balance sheet of the Company as
of  March  31,  1998  that  remain  uncollected  as of  November  1,  1998  (the
"Uncollected Receivables"), it being understood by the parties that any accounts
receivable of the Company  arising after March 31, 1998 and prior to the Closing
Time shall be the  responsibility of OAOT after the Closing.  OAOT shall provide
written  notice to OAO of the aggregate  amount of the  Uncollected  Receivables
(which  shall  include the  reduction  for the A/R Reserve  Amount),  if any, by
November 15, 1998 or as promptly thereafter as practicable,  and upon receipt of
such notice,  OAO shall pay OAOT the amount  specified in such notice  within 15
days.

     2.10  Required   Consents.   Within  30  days  of  the  Closing  Date,  the
Shareholders  shall have obtained all Required Consents without any modification
that OAOT deems unacceptable,  including,  without limitation, the assignment of
all Contracts required by the terms thereof (other than the IBM Consents and the
Sanwa Consent,  which shall be obtained prior to or  contemporaneously  with the
entering into of this Agreement).

3.   Closing.

<PAGE>



          (f) the parties shall also deliver to each other the agreements, legal
     opinions and other documents and instruments  specified in Sections 7 and 8
     and such other items as may be reasonably requested.

4.   Representations and Warranties of the Selling Parties.

     The Selling  Parties hereby jointly and severally  represent and warrant to
OAOT as follows:

     4.1 Corporate  Status.  Each Selling Party that is a corporation  (each,  a
"Corporate Selling Party") is a corporation duly organized, validly existing and
in good standing under the Laws under which it was incorporated and is qualified
to do business as a foreign corporation in any jurisdiction where it is required
to  be  so  qualified,  except  where  the  failure  so to  qualify  would  not,
individually or in the aggregate,  have a Material  Adverse Effect.  The Charter
Documents and bylaws of the Corporate  Selling  Parties that have been delivered
to OAOT as of the  date  hereof  are  effective  under  applicable  Laws and are
current, correct and complete.

     4.2 Authorization. The Company has the requisite power and authority to own
its Assets and carry on its  business as  presently  conducted.  Each  Corporate
Selling Party has the  requisite  power and authority to execute and deliver the
Transaction  Documents  to which it is a party and to perform  the  Transactions
performed or to be performed by it. Such execution,  delivery and performance by
each  Corporate  Selling  Party  have  been  duly  authorized  by all  necessary
corporate  action.  Each  Transaction  Document  executed  and  delivered by any
Selling Party as of the date hereof has been duly executed and delivered by such
Selling  Party and  constitutes  a valid and binding  obligation of such Selling
Party, enforceable against such Selling Party in accordance with its terms.

     4.3 Consents and Approvals.  Except for any consents  specified in Schedule
4.3 (the "Required Consents"), neither the execution and delivery by any Selling
Party of the Transaction  Documents to which it is a party,  nor the performance
of the Transactions  performed or to be performed by any Selling Party, will (a)
require  any  filing,  consent,   renegotiation  or  approval,   conflict  with,
constitute a Default or cause any payment  obligation to arise under (i) any Law
or Court Order to which any Selling Party or its  properties or other assets may
be  subject,  (ii) with  respect to any  Corporate  Selling  Party,  the Charter
Documents  or  bylaws of such  Corporate  Selling  Party or (iii) any  Contract,
Governmental  Permit or other  document to which any Selling Party is a party or
by which the properties or other assets of any Selling Party may be subject,  or
(b) result in the creation or imposition of any Encumbrance  upon the Company or
any of  the  Assets.  The  Selling  Parties  have  obtained  the  IBM  Consents.
Contemporaneously  with entering into this  Agreement,  the Selling Parties will
have obtained the Sanwa Consent.

     4.4 Capitalization and Stock Ownership.  The total authorized capital stock
of the Company consists of 1,000 shares of Common Stock, 500 shares of which are
issued and outstanding on the date hereof  immediately prior to the Closing (the
"Existing Shares"). There are no existing options,  warrants, calls, commitments
or other rights of any character  (including  conversion  or preemptive  rights)
relating to the  acquisition  of any issued or unissued  capital  stock or other
securities  of the  Company.  All of the  Existing  Shares are duly and  validly
authorized and



                                       13

<PAGE>



issued, fully paid and non-assessable.  The Shareholders are the sole record and
beneficial  owners of all of the issued and outstanding  Existing  Shares.  Each
Shareholder owns of record the number of Existing Shares set forth opposite such
Shareholder's  name in  Exhibit  "A"  hereto.  The  Company  complied  with  all
applicable Laws in connection with the issuance of the Existing Shares, and none
of the Existing Shares was issued in violation of any Contract  binding upon the
Company.  All of the Securities are freely transferable except as may be limited
by any applicable  securities  Laws. Upon completion of the  Transactions at the
Closing, OAOT shall receive valid title to all of the Securities, free and clear
of all Encumbrances.

     4.5  Financial  Statements.  The Company has  delivered to OAOT correct and
complete  copies of (a)  financial  statements  of the  Company,  consisting  of
balance  sheets  as of  September  30,  1995,  1996  and  1997  and the  related
statements of income, retained earnings and cash flows for the years then ended,
all of which  were  reviewed  by  Deloitte  &  Touche  LLP,  independent  public
accountants  ("Deloitte"),  and  were  included  in the  consolidated  financial
statements  of OAO for such  periods  which were  audited by  Deloitte,  and (b)
interim financial statements of the Company, consisting of a balance sheet as of
May 31, 1998 and the related  statements of income,  retained  earnings and cash
flows for the eight-month  period then ended.  All such financial  statements of
the Company are referred to herein  collectively as the "Financial  Statements."
The  Financial  Statements  are accurate and complete and are  consistent in all
material respects with the Books and Records of the Company,  and there have not
been any material  transactions  that have not been  recorded in the  accounting
records underlying such Financial Statements. The Financial Statements have been
prepared on a consistent  basis with,  and form in part,  the basis on which the
consolidated financial statements of OAO were prepared. The Financial Statements
have been prepared in accordance  with GAAP  consistently  applied,  and present
fairly the financial  position and Assets and  Liabilities  of the Company as of
the dates  thereof,  and the  results of its  operations  and cash flows for the
periods then ended, subject, in the case of unaudited Financial  Statements,  to
normal  recurring  year-end  adjustments  and the absence of notes.  The balance
sheet of the Company as of September  30, 1997 that is included in the Financial
Statements is referred to herein as the "Balance Sheet," and the date thereof is
referred to as the "Balance Sheet Date."

     4.6  Title  to  Assets  and  Related  Matters.  The  Company  has  good and
marketable title to, valid leasehold  interests in or valid licenses to use, all
of its Assets, free from any Encumbrances except those specified in Schedule 4.6
(the  "Permitted  Encumbrances").  The use of the  Assets is not  subject to any
Encumbrances  (other  than  Permitted  Encumbrances),  and  such  use  does  not
materially  encroach on the property or rights of any Person.  All Real Property
and  tangible  personal  property  (other  than  Inventory)  of the  Company are
suitable for the purposes for which they are used, in good working condition and
repair,  reasonable  wear and tear  excepted,  and free from any known  defects,
except such minor defects that would not, individually or in the aggregate, have
a Material Adverse Effect. Any Software Product included in the Assets, together
with all know-how  and  processes  used in  connection  therewith,  functions as
intended  and is in  machine-readable  form.  The Assets  constitute  all of the
assets  required for the  continued  operation of the Company as conducted as of
the Balance Sheet Date.

     4.7 Real  Property.  Schedule  4.7  describes  all real  estate used in the
operation  of the  Company  as  well as any  other  real  estate  that is in the
possession of or leased by the Company and



                                       14

<PAGE>



the improvements (including buildings and other structures) located on such real
estate (collectively, the "Real Property"), and lists any leases under which any
such Real Property is possessed (the "Real Estate  Leases").  The Company has no
ownership  interest in any Real Property.  The Company has not previously owned,
leased or  otherwise  operated  any other real estate other than as set forth in
Schedule 4.7. The Company has made available to OAOT correct and complete copies
of the Real Estate  Leases,  as amended and as  currently  in effect.  Each Real
Estate Lease is valid and in full force and effect and, to the Selling  Parties'
knowledge,  constitutes the legal,  valid and binding obligation of the landlord
thereunder,  enforceable  in  accordance  with its  terms.  Neither  OAO nor the
Company  is in  Default  under any Real  Estate  Lease,  all rent and other sums
payable by or to OAO or the Company  thereunder  are current  within  applicable
notice and grace  periods  and no  landlord  under any Real  Property  Lease has
asserted  a Default  on the part of OAO or the  Company  that  would give it the
right to terminate such Real Estate Lease or set off against rent and other sums
payable by OAO or the Company thereunder and, to the Selling Parties' knowledge,
there is no Default under any Real Estate Lease by any other party.  Neither OAO
nor the  Company  has  received  notice  that any  landlord  intends  to cancel,
terminate  or refuse to renew any Real Estate Lease or to exercise or decline to
exercise  any  option  or  other  right  thereunder.   All  improvements  to  be
constructed  by any landlord under any Real Estate Lease have been completed and
the use of the Real  Property in the conduct of the business of the Company is a
permitted  use  under  the  terms of each  Real  Estate  Lease.  All of the Real
Property  is usable in the  ordinary  course of  business  and  conforms  in all
material respects with any applicable Laws relating to its construction, use and
operation.  The Real Property  complies with  applicable  zoning Laws.  OAO, the
Company or the landlord of any Real  Property  leased or occupied by the Company
has  obtained  all  licenses and  rights-of-way  from  governmental  entities or
private  parties that are necessary to ensure  vehicular and pedestrian  ingress
and egress to and from the Real Property.

     4.8  Certain  Personal  Property.  Attached  as  Schedule  4.8  hereto is a
complete  fixed  asset  schedule,  describing  all  items of  tangible  personal
property  that were  included  in the  Balance  Sheet.  Except as  specified  in
Schedule  4.8,  since the Balance  Sheet Date,  the Company has not acquired any
items of tangible personal property that have, in each case, a carrying value in
excess of $20,000,  or an  aggregate  carrying  value of  $100,000.  All of such
personal  property  included  in such  fixed  asset  schedule  is  usable in the
ordinary  course of business  and  conforms in all  material  respects  with any
applicable  Laws relating to its  construction,  use and  operation.  Except for
those items  subject to the Non-Real  Estate Leases and as set forth in Schedule
4.8, no Person  other than the Company  owns any  vehicles,  equipment  or other
tangible  assets used by the Company or that are  necessary for the operation of
the Company.

     4.9  Non-Real  Estate  Leases.  Schedule  4.9 lists all assets and property
(other than Real Property) that have been used in the conduct of the business of
the  Company and that are  possessed  by the  Company  under an existing  lease,
including all trucks, automobiles,  forklifts,  machinery,  equipment, furniture
and computers,  except for any lease under which the aggregate  annual  payments
are less than $10,000 (each, an "Immaterial Lease"). Schedule 4.9 also lists the
leases  under  which  such  assets  and  property  listed  in  Schedule  4.9 are
possessed.  All of such leases  (excluding  Immaterial  Leases) are  referred to
herein as the "Non-Real  Estate Leases." Each Non-Real Estate Lease is valid and
in full force and effect and, to the Selling Parties' knowledge, constitutes the
legal,  valid and binding  obligation of the lessor  thereunder,  enforceable in
accordance



                                       15

<PAGE>



with its terms.  The Company is not in Default under any Non-Real  Estate Lease,
all lease  payments and other sums payable by or to the Company  thereunder  are
current  within  applicable  notice and grace  periods  and no lessor  under any
Non-Real  Estate  Lease has  asserted a Default on the part of the Company  that
would  give it the right to  terminate  such  Non-Real  Estate  Lease or set off
against lease payments and other sums payable by the Company  thereunder and, to
the Selling  Parties'  knowledge,  there is no Default under any Non-Real Estate
Lease by any other party.  The Company has not  received  notice that any lessor
intends to cancel or  terminate  any  Non-Real  Estate  Lease or to  exercise or
decline to exercise any option or other right thereunder.

     4.10 Accounts Receivable.  The accounts receivable set forth on the Balance
Sheet or arising  since the Balance  Sheet Date (a) are valid and  genuine,  (b)
have arisen only in the  ordinary  course of business out of bona fide sales and
deliveries  of goods or  performance  of services,  (c) are not subject to valid
defenses,  set-offs  or  counterclaims  and (d) are  collectible  in full at the
recorded  amounts  thereof  (without  resort to  litigation  or  assignment to a
collection  agency)  within 90 days  after  billing,  net of any  allowance  for
doubtful  accounts  reflected on the Balance  Sheet.  The allowance for doubtful
accounts  reflected on the Balance Sheet has been  determined in accordance with
GAAP consistently applied. The Company knows of no facts or circumstances (other
than  general  economic  conditions)  that are likely to result in any  material
increase in the  uncollectibility  of such accounts  receivable in excess of any
allowance therefor set forth on the Balance Sheet.

     4.11  Inventory.  The  Inventory set forth on the Balance Sheet or acquired
since the Balance Sheet Date consists of items of good,  usable and merchantable
quality in all material  respects and does not include  obsolete or discontinued
items.  Such  Inventory  is of  such  quality  as may  be  required  to  satisfy
applicable quality control standards of any governmental authority. All finished
goods  included in such  Inventory  are saleable as current  inventories  at the
current  price  thereof in the ordinary  course of business.  Such  Inventory is
recorded  in the  Financial  Statements  at the  lower of cost or  market  value
determined in accordance with GAAP, and no write-down of such Inventory has been
made or should have been made pursuant to GAAP during the past two years.

     4.12  Liabilities.  The Company does not have any Liabilities,  and none of
the Assets is subject to any Liabilities,  except (a) as specifically  disclosed
on the Balance Sheet and not  heretofore  paid or  discharged,  (b)  Liabilities
incurred in the ordinary course since the Balance Sheet Date that,  individually
or in the aggregate,  are not material and (c)  Liabilities  under any Contracts
that are  specifically  disclosed in the Schedules hereto (or not required to be
disclosed  because of the term or amount  involved) that were not required under
GAAP to have been specifically disclosed or reserved for on the Balance Sheet.

     4.13 Taxes and Tax  Returns.  All  federal,  state,  local and  foreign tax
returns, reports, statements and other similar filings required to be filed with
respect to any federal,  state,  local or foreign Taxes of the Company (the "Tax
Returns") have been timely filed with the appropriate  governmental  authorities
in all jurisdictions in which such Tax Returns are required to be filed, and all
such Tax Returns  properly  reflect the Liabilities of the Company for Taxes for
the periods,  property or events covered thereby. All Taxes, including,  without
limitation,  those which are called for by the Tax  Returns,  or  heretofore  or
hereafter claimed to be due by any taxing authority from the Company,  have been
properly accrued or paid. The accruals for Taxes contained in the Balance



                                       16

<PAGE>



Sheet are adequate to cover the  Liabilities  of the Company for Taxes as of the
Balance Sheet Date and include  adequate  provision  for all deferred  Taxes and
nothing has occurred  subsequent  to the Balance  Sheet Date to make any of such
accruals  inadequate,  and the accruals for Taxes to be contained in the Closing
Balance Sheet will be adequate to cover the Liabilities of the Company for Taxes
as of the Closing  Time and will  include  adequate  provision  for all deferred
Taxes.  The  Company  has not  received  any notice of  assessment  or  proposed
assessment  in  connection  with any Tax  Returns  and there are no pending  tax
examinations of or tax claims asserted against the Company or any of the Assets.
The  Company  has not  extended,  or waived the  application  of, any statute of
limitations  of any  jurisdiction  regarding the assessment or collection of any
Taxes. There are no tax liens on any of the Assets. The Company has no knowledge
of any basis for any  additional  assessment of any Taxes.  The Company has made
all deposits  required by Law to be made with respect to employees'  withholding
and other employment Taxes, including,  without limitation,  the portion of such
deposits  relating to Taxes imposed upon the Company.  The Company has not taken
any  action  that  would have the effect of  deferring  any  Liabilities  of the
Company for Taxes from a pre-Closing period to any period commencing on or after
the Closing Time.

     4.14  Subsidiaries.  The Company does not own, directly or indirectly,  any
interest or investment (whether equity or debt) in any corporation, partnership,
limited liability company, business, trust, joint venture or other legal entity.

     4.15 Legal Proceedings and Compliance with Law.

     (a) Except as set forth in Schedule 4.15(a),  there is no Litigation in any
court or before any governmental entity or arbitrator that is pending or, to any
Selling Party's  knowledge,  threatened against or related to the Company or any
of the  Assets or which  seeks to enjoin or obtain  damages  in  respect  of the
consummation  of the  Transactions.  There  has been no  Default  under any Laws
applicable to the Company,  including Environmental Laws (defined below), except
for any  Defaults  that  would not,  individually  or in the  aggregate,  have a
Material  Adverse Effect,  and the Company has not received any notices from any
governmental  entity  regarding any alleged Defaults under any Laws. The Company
is not a party to, and none of the Assets is subject to, the  provisions  of any
judgment, order, writ, injunction, decree or award of any governmental authority
or  any  arbitrator,  nor is  there  any  Court  Order  that  might  affect  the
Transactions.  There  has  been no  Default  with  respect  to any  Court  Order
applicable  the  Company or the Assets.  Neither  the Company nor any  director,
officer,  employee or agent of, or any consultant to, the Company has unlawfully
offered, paid or agreed to pay, directly or indirectly, any money or anything of
value to or for the  benefit  of any  individual  who is or was an  official  or
employee  or  candidate  for  office of the  government  of any  country  or any
political  subdivision,  agency or  instrumentality  thereof or any  employee or
agent of any customers or suppliers of the Company.

     (b) Without limiting the generality of Section 4.15(a),  there has not been
and there  does not  exist any  Environmental  Condition  (defined  below) at or
relating to (i) any  premises at which the  operations  of the Company have been
conducted,  (ii) any property owned, leased, occupied or operated at any time by
the Company,  by any Person controlled by any Affiliate of the Company or by any
predecessor  of any of the  foregoing  or (iii) any  property at which wastes or
Hazardous  Substances  have been  deposited  or  disposed  of by, from or at the
behest or direction of any of the



                                       17

<PAGE>



foregoing,  nor has any  Selling  Party  received  written  notice  of any  such
Environmental  Condition.  "Environmental  Condition"  means  any  condition  or
circumstance, including the presence of Hazardous Substances, whether created by
the Company or any third party,  at or relating to any such property or premises
that  (A)  requires  or  could  require  assessment,  investigation,  abatement,
correction,  removal or remediation  under any  Environmental  Law, (B) gives or
could give rise to any civil or criminal  Liability under any  Environmental Law
or (C) constitutes or could create a public or private nuisance.  "Environmental
Law" means all Laws and Court Orders  relating to pollution or protection of the
environment  as well as any  principles of common law under which a party may be
held liable for the release or discharge of any materials into the environment.

     (c) The Company has  delivered to OAOT  correct and complete  copies of any
written  environmental  reports,  studies or  assessments  in the  possession or
control of any  Selling  Party  that  relate to the  Company,  the Assets or any
Environmental Condition.

     (d) Except in those cases where the failure would not,  individually  or in
the aggregate,  have a Material Adverse Effect, (i) the Company has obtained and
is in full compliance with all Governmental  Permits, all of which are listed in
Schedule 4.15(d) along with their respective expiration dates, that are required
for  the  operation  of the  Company  as  currently  operated,  (ii)  all of the
Governmental Permits are currently valid and in full force and (iii) the Company
has filed such timely and complete renewal  applications as may be required with
respect to its  Governmental  Permits.  To the Selling  Parties'  knowledge,  no
revocation,   cancellation  or  withdrawal  thereof  has  been  threatened.  Any
Governmental   Permits  that  cannot  be  transferred  in  connection  with  the
consummation of the Transactions are identified in Schedule 4.15(d).

     4.16 Contracts.

     Intellectual Property, Software Products or technical assistance;

          (x) Contracts for any capital  expenditures or leasehold  improvements

     (b) Correct and complete  copies of the  Contracts  listed in Schedule 4.16

     (a) Schedule  4.21  contains a current,  correct and  complete  list of all
Benefit  Plans  sponsored or  maintained  by the Company or any Affiliate of the
Company  or under  which  the  Company  may be  obligated  with  respect  to any
Employees  or former  employees  of the Company or  beneficiaries  of any of the
foregoing.  The Company has delivered to OAOT correct and complete (i) copies of
all such  Benefit  Plan  documents  and all other  material  documents  relating
thereto, including (if applicable) all summary plan descriptions, summary annual
reports and insurance  contracts,  (ii) detailed summaries of all such unwritten
Benefit  Plans,  (iii)  copies  of the  most  recent  financial  statements  and
actuarial  reports with respect to all such  Benefit  Plans for which  financial
statements  or  actuarial  reports are  required or have been  prepared and (iv)
copies of all annual  reports  for all such  Benefit  Plans  (for  which  annual
reports are required)  prepared  within the last three years.  Each such Benefit
Plan  providing  benefits  that are  funded  through  a policy of  insurance  is
indicated  by the word  "insured"  placed by the listing of the Benefit  Plan in
Schedule  4.21.  The Company  does not have any  Liability  with  respect to any
employee  benefit  plan or  arrangement  other than with  respect to the Benefit
Plans listed in Schedule 4.21.

     (b) All such Benefit Plans conform (and at all times have conformed) in all
material  respects to, and are being  administered and operated (and have at all
time  been   administered  and  operated)  in  material   compliance  with,  the
requirements  of ERISA,  the Code and all other  applicable  Laws.  All returns,
reports and disclosure  statements  required to be made under ERISA and the Code
with  respect to all such  Benefit  Plans have been timely  filed or  delivered.
There have not been any  "prohibited  transactions,"  as such term is defined in
Section  4975 of the Code or Section  406 of ERISA  involving  any such  Benefit
Plans,  that could  subject the Company to any  material  penalty or Tax imposed
under the Code or ERISA.

     (c) Any such Benefit Plan that is intended to be  qualified  under  Section
401(a) of the Code and exempt from tax under Section 501(a) of the Code has been
determined by the Internal  Revenue Service to be so qualified or an application
for such determination is pending. Any such determination that has been obtained
remains in effect and has not been revoked,  and with respect to any application
that is pending,  the Company has no reason to suspect that such application for
determination  will be denied.  Nothing has occurred  since the date of any such
determination  that is reasonably likely to affect adversely such  qualification
or  exemption,  or result in the  imposition  of excise Taxes or income Taxes on
unrelated  business  income  under the Code or ERISA  with  respect  to any such
Benefit Plan.

     (d) The Company does not sponsor or contribute  to, and has not in the past
sponsored,  contributed  to or had an obligation  to  contribute  to, and has no
Liability with respect to, any defined benefit plan subject to Title IV of ERISA
or any  multiemployer  plan (as defined in Section 3(37) of ERISA),  nor does it
have a current or contingent  obligation to contribute to any multiemployer plan
(as defined in Section  3(37) of ERISA).  For purposes of this Section  4.21(d),
the term  "Company"  shall  include  any  corporation  that is a  member  of any
controlled group of corporations (as defined in Section 414(b) of the Code) that
includes the Company,  any trade or business (whether or not incorporated)  that
is under  common  control  (as  defined in Section  414(c) of the Code) with the
Company,  any organization  (whether or not incorporated) that is a member of an
affiliated service



                                       24

<PAGE>



group (as defined in Section  414(m) of the Code) that  includes the Company and
any other  entity  required to be  aggregated  with the Company  pursuant to the
regulations issued under Section 414(o) of the Code.

     (e) There  are no  pending  or,  to the  knowledge  of any  Selling  Party,
threatened  claims by or on behalf of any such Benefit Plans, or by or on behalf
of any  individual  participants  or  beneficiaries  of any such Benefit  Plans,
alleging any breach of  fiduciary  duty on the part of the Company or any of its
officers,  directors or employees  under ERISA or any other  applicable  Law, or
claiming  benefit  payments  other than those made in the ordinary  operation of
such plans,  nor is there, to the knowledge of any Selling Party,  any basis for
such  claim.  Such  Benefit  Plans are not the subject of any pending or, to the
knowledge of any Selling Party, threatened investigation, audit or action by the
Internal  Revenue  Service,  the  Department  of  Labor or the  Pension  Benefit
Guaranty Corporation ("PBGC").

     (f) The  Company  or OAO,  if  applicable,  has  timely  made all  required
contributions  under such Benefit  Plans  including  any matching  contributions
under a 401(k)  plan for the  benefit of the  Employees  and the  payment of any
premiums  payable to the PBGC and other insurance  premiums.  There have been no
accumulated  funding  deficiencies  (as  defined in  Section  412 of the Code or
Section 302 of ERISA) with respect to any such Benefit Plan and no request for a
waiver from the Internal  Revenue  Service  with respect to any minimum  funding
requirement  under  Section 412 of the Code.  The Company has not  incurred  any
Liability  for any Tax,  excise  Tax,  penalty  or fee with  respect to any such
Benefit  Plan,  and no event  has  occurred  and no  circumstance  exists or has
existed  that  could  give  rise to any such  Liability.  The  execution  of and
performance of the Transactions  contemplated by this Agreement will not (either
alone or upon the occurrence of any  additional or subsequent  events) result in
any payment,  acceleration,  vesting or increase in benefits with respect to any
current or former  employee  of the Company  that would be an "excess  parachute
payment" under Section 280G of the Code.

     (g) With  respect  to any such  Benefit  Plan that is an  employee  welfare
benefit plan  (within the meaning of Section 3(1) of ERISA) (a "Welfare  Plan"),
(i) each  Welfare  Plan for which  contributions  are  claimed by the Company as
deductions  under any provision of the Code is in material  compliance  with all
applicable requirements  pertaining to such deduction,  (ii) with respect to any
welfare  benefit fund (within the meaning of Section 419 of the Code) related to
a Welfare Plan, there is no disqualified  benefit (within the meaning of Section
4976(b) of the Code) that would result in the  imposition of a Tax under Section
4976(a) of the Code,  (iii) any Benefit Plan that is a group health plan (within
the meaning of Section 4980B(g)(2) of the Code) complies,  and in each and every
case has complied and been administered in accordance with all of the applicable
material  requirements  of Section 4980B of the Code,  ERISA,  Title XXII of the
Public Health Service Act, the Social Security Act and other applicable Laws and
(iv) all Welfare  Plans may be amended or terminated at any time on or after the
Closing  Date.  No Benefit  Plan  provides  any  health,  life or other  welfare
coverage to Employees of the Company or former  employees of the Company  beyond
termination  of their  employment  with the Company,  by reason of retirement or
otherwise,  other than  coverage as may be required  under  Section 4980B of the
Code or Part 6 of ERISA, or under the continuation of coverage provisions of the
Laws of any state or locality.

contains  a list  of the  names  of  each  of the  ten  customers  that,  in the

therein or otherwise  delivered by or on behalf of any Selling  Party to OAOT in

Parties  contained  in  this  Agreement,  disregarding  all  qualifications  and
exceptions  herein relating to materiality or Material Adverse Effect,  are true

Material Adverse Effect.

5.   Representations and Warranties of OAOT.

     OAOT hereby represents and warrants to the Selling Parties as follows:

     5.1  Corporate  Status.  OAOT  is a  corporation  duly  organized,  validly
existing and in good standing under the Laws under which it was incorporated.

     5.2  Authorization.  OAOT has the requisite  power and authority to execute
and deliver the Transaction  Documents to which it is a party and to perform the
Transactions  performed or to be performed by it, and such  execution,  delivery
and  performance  by OAOT have been duly  authorized by all necessary  corporate
action. Each Transaction  Document executed and delivered by OAOT as of the date
hereof has been duly executed and delivered by OAOT and  constitutes a valid and
binding  obligation of OAOT,  enforceable  against OAOT in  accordance  with its
terms.

     5.3 Consents and  Approvals.  Except as set forth in Schedule 5.3,  neither
the execution and delivery by OAOT of the Transaction Documents to which it is a

any Law or Court Order to which OAOT is subject,  (b) the Charter  Documents  or
bylaws of OAOT or (c) any  Contract,  Governmental  Permit or other  document to

any material fact necessary in order to make the statements  contained herein or
therein not misleading.

6.   Post-Closing Covenants.

     6.1 Covenant Not to Compete. Except with the prior written consent of OAOT,
OAO and,  subject  to  Section  6.3,  its  Affiliates  other  than Hill  (each a
"Restricted Party") shall not, at any time within the Restricted Period (defined
below),  directly or  indirectly,  engage in, or have any  interest on behalf of
itself or others in any Person or  business  (whether as an  employee,  officer,
director, agent, security holder, creditor, partner, joint venturer, beneficiary
under a trust,  investor,  consultant  or  otherwise)  that  engages  within the
Restricted   Territory   (defined   below)   in  the   provision   of  time  and
materials-based  contract  staffing  augmentation  services  for the  commercial
information  technology  business segment.  In furtherance of the foregoing,  no
Restricted Party during the Restricted Period shall contact any of the Employees
for the purpose of hiring or retaining  any of such  Employees  for  employment,
consulting or similar  purposes.  The term "Restricted  Period" means the period
beginning on the date hereof and ending on the third  anniversary of the Closing
Date. The "Restricted  Territory" means the area comprising the entire world. In
the  event of  Litigation  involving  this  Agreement,  if a court of  competent
jurisdiction  determines that the scope of this Section 6.1 or of Section 6.2 is
too broad in any  respect,  then the scope  shall be  deemed  to be  reduced  or
narrowed to such scope as is found  lawful and  reasonable  by such  court.  OAO
acknowledges,  however, that this Section 6.1 has been negotiated by the parties
and that the  geographical  and time  limitations,  as well as the limitation on
activities,  are  reasonable  in light of the  circumstances  pertaining  to the
business of the Company.

     6.2 Confidential  Information.  For an indefinite period after the Closing,
no  Restricted  Party  shall  divulge,  communicate  or  use  in  any  way,  any
Confidential Information of the Company.

     6.3 Affiliates and Hill Limitations. The terms of Section 6.1 and 6.2 shall
apply to OAO and any of its  Affiliates  (except  Hill) to the same extent as if
they were parties hereto,  and OAO shall take whatever  actions may be necessary
to cause any such  Affiliate to adhere to the terms of Section 6.1 and 6.2. Hill
shall continue to be subject to the limitations on competition, solicitation and
use of confidential  information  contained in the Employment  Agreement entered
into in April 1996 between Hill and OAOT.

     6.4 Injunctive  Relief.  In the event of any breach or threatened breach by
any  Restricted  Party of any  provision  of Section  6.1 or 6.2,  OAOT shall be
entitled to injunctive or other equitable  relief,  restraining  such party from
using or disclosing  any  Confidential  Information in whole or in part, or from
engaging  in conduct  that would  constitute  a breach of the  obligations  of a
Restricted  Party under  Section 6.1 or 6.2. Such relief shall be in addition to
and not in lieu of any other remedies that may be available, including an action
for the recovery of damages.

     6.5 Expenses.  Each of the parties hereto shall pay its or his own expenses
for lawyers, accountants,  consultants, investment bankers, brokers, finders and
other advisors with respect to the Transactions.

     6.6 OAO  Affiliates.  Each Selling  Party shall cause any Affiliate of such
Selling Party to comply with the terms and  conditions of this Agreement and the
other  Transaction  Documents to the same extent as if they were parties to this
Agreement and the other Transaction Documents



                                       30

<PAGE>



to the extent  necessary to consummate the  Transactions  in accordance with the
Transaction Documents.

     6.7 338(h)(10) Tax Election and Certain Tax Matters.

     (a) OAO agrees,  if so  requested  by OAOT,  to join with OAOT in making an
election under Section  338(h)(10) of the Code (and any corresponding  elections
under  state,  local or foreign Tax Law)  (collectively,  a "Section  338(h)(10)
Election")  with respect to the purchase and sale of its  Securities  hereunder.
OAO shall be  responsible  for and will pay any Tax,  including any Liability of
the Company for Tax resulting from the application to it of Treasury  Regulation
ss.1.338(h)(10)-  1(f)(5),  attributable to the making of the Section 338(h)(10)
Election and will indemnify and hold harmless each Indemnified  Buyer Party from
and  against any  Damages  arising out of any failure to pay such Tax.  OAO also
shall be  responsible  for and will pay any  state,  local or  foreign  Tax (and
indemnify and hold harmless  each  Indemnified  Buyer Party from and against any
Damages arising out of any failure to pay such Tax)  attributable to an election
under state,  local or foreign Tax Law similar to the election  available  under
Section  338(g) of the Code (or which  results  from the  making of an  election
under  Section  338(g) of the Code) with respect to the purchase and sale of the
Securities hereunder.

     (b) OAOT  shall  prepare  or cause to be  prepared  and file or cause to be
filed all tax returns for the Company for all periods  ending on or prior to the
Closing  Time which are filed  after the  Closing  Time  other  than  income tax
returns  with respect to periods for which a  consolidated,  unitary or combined
income tax return of OAO will include the  operations of the Company.  OAOT will
permit  OAO to review  and  comment  on each such tax  return  described  in the
preceding  sentence  prior to  filing.  OAO shall be  responsible  for and shall
reimburse  OAOT for Taxes of the Company  with  respect to such  periods  within
fifteen 15 days after payment by OAOT of such Taxes 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 audited Closing Balance Sheet.

     (c) OAOT  shall  prepare  or cause to be  prepared  and file or cause to be
filed all tax  returns of the Company  for all  periods  which begin  before the
Closing Time and end after the Closing Time.  OAO shall be  responsible  for and
shall  pay to OAOT  within 15 days  after the date on which  Taxes are paid with
respect to such  periods  an amount  equal to the  portion  of such Taxes  which
relates to the portion of such taxable  period ending on the Closing Time 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 face of the audited  Closing  Balance
Sheet.  For  purposes  of this  Section  6.7,  in the case of any Taxes that are
imposed on a periodic  basis and are payable for a taxable  period that includes
(but does not end on) the Closing Time, the portion of such Tax which relates to
the portion of such taxable  period  ending on the Closing Time shall (i) in the
case of any Taxes other than Taxes based upon or related to income or  receipts,
be deemed to be the amount of such Tax for the entire taxable period  multiplied
by a fraction the numerator of which is the number of days in the taxable period
ending on the Closing Time and the denominator of which is the number of days in
the entire taxable period, and (ii) in the case of any Tax based upon or related
to income or receipts, be deemed equal to the amount which



                                       31

<PAGE>



would be payable if the relevant  taxable  period ended on the Closing Time. Any
credits  relating  to a taxable  period  that  begins  before and ends after the
Closing Time shall be taken into account as though the relevant  taxable  period
ended on the Closing Time.  All  determinations  necessary to give effect to the
foregoing  allocations  shall be made in a manner consistent with prior practice
of the Company.

     (d) OAOT and OAO shall  cooperate  fully,  as and to the extent  reasonably
requested  by the other  party,  in  connection  with the filing of tax  returns
pursuant to this Section 6.7 and with any audit,  Litigation or other proceeding
with respect to such Taxes.  Such  cooperation  shall  include the 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 employees  available on a mutually convenient basis to provide additional
information and  explanation of any material  provided  hereunder.  OAOT and OAO
agree (i) to retain all books and records with respect to Tax matters  pertinent
to the Company  relating to any taxable period beginning before the Closing Time
until the expiration of the statute of limitations  (and, to the extent notified
by the other party, any extensions  thereof) of the respective  taxable periods,
and to abide by all record  retention  agreements  entered  into with any taxing
authority,  and (ii) to give the other party reasonable  written notice prior to
transferring,  destroying or  discarding  any such books and records and, if the
other party so requests,  OAOT or OAO, as the case may be, shall allow the other
party to take possession of such books and records.

     (e) OAOT and OAO further agree, upon request,  to use their best efforts 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,   without  limitation,   with  respect  to  the
Transactions contemplated hereby.

     (f) OAOT and OAO further  agree,  upon request,  to provide the other party
with all information  that a party may be required to report pursuant to Section
6043 of the Code and all Treasury Regulations promulgated thereunder.

     6.8  Employee  Benefits.  OAO agrees to  maintain  (and make  contributions
thereunder,  if  applicable)  all  Benefits  Plans under  which it is  currently
obligated  with respect to any Employees or former  employees of the Company and
beneficiaries  thereof  (the  "Company  Participants"),  for the benefit of such
Company  Participants,  subject to the terms relating  thereto  contained in the
Administrative Services Agreement, until the earlier of (a) December 31, 1998 or
(b) the date or dates  specified in a written notice or notices to OAO from OAOT
with respect to the  discontinuance  by OAO of the  maintenance of any or all of
such Benefits Plans for the benefit of the Company  Participants,  none of which
dates shall be later than  December 31,  1998.  In the event that OAOT shall not
have  provided  the notice  described  in the  preceding  sentence  on or before
October 1, 1998 with respect to each such Benefit Plan, by no later than October
1,  1998,   OAOT  shall  provide  written  notice  to  OAO  of  the  anticipated
discontinuance  date of each  Benefit  Plan  maintained  by OAO for the  Company
Participants, none of which dates shall be later than December 31, 1998, and, if
applicable,  the proposed  method of transferring  participation  by the Company
Participants  in the Benefits  Plans to employee  benefit  plans  maintained  or
established by OAOT or the Company.



                                       32

     6.9  Certain  Taxes.  All  transfer,   documentary,   sales,   use,  stamp,
registration  and  other  such  Taxes  and fees  (including  any  penalties  and
interest)  incurred in  connection  with the  Transactions  shall be paid by the
Shareholders when due, and the Shareholders will, at their own expense, file all
necessary tax returns and other documentation with respect to all such transfer,
documentary, sales, use, stamp, registration and other such Taxes and fees.

successors and assigns, and its officers,  directors,  employees,  shareholders,
agents,  Affiliates  and any Person who controls  OAOT within the meaning of the
Securities Act or the Exchange Act (each, an "Indemnified Buyer Party") from and
against any liabilities,  claims, demands, judgments,  losses, costs, damages or
expenses whatsoever  (including  reasonable  attorneys',  consultants' and other
professional  fees and  disbursements  of every  kind,  nature  and  description
incurred by such Indemnified Buyer Party in connection therewith) (collectively,
"Damages") that such  Indemnified  Buyer Party may sustain,  suffer or incur and
that result from, arise out of or relate to (a) any breach of any representation
or warranty of any Selling Party contained in this Agreement,  or (b) any breach
of any covenant or agreement  (including  certain  covenants and  agreements set
forth as conditions in Section 7 hereof) of any Selling Party  contained in this
Agreement;  provided,  however,  that in no event  shall Hill be liable for more
than his  Proportionate  Interest in any Damages  paid to an  Indemnified  Buyer
Party pursuant to this Section 9.1.

     9.2 By OAOT.  From and after the Closing  Date,  to the extent  provided in

successors and assigns, and, if applicable, its officers, directors,  employees,
shareholders,  agents,  Affiliates and any Person who controls any Selling Party
within  the  meaning  of the  Securities  Act  or the  Exchange  Act  (each,  an
"Indemnified  Seller Party") from and against any Damages that such  Indemnified
Seller Party may sustain,  suffer or incur and that result from, arise out of or
relate to (a) any breach of any  representation or warranty of OAOT contained in
this Agreement, or (b) any breach of any covenant or agreement of OAOT contained
in this Agreement.

     9.3 Procedure for Claims.

     (a) An Indemnified Buyer Party or an Indemnified  Seller Party that desires
to seek indemnification  under any part of this Section 9 (each, an "Indemnified
Party")  shall  give  notice (a "Claim  Notice")  to each party  responsible  or
alleged to be responsible for indemnification  hereunder (an "Indemnitor") prior
to any applicable  Expiration  Date specified  below.  Such notice shall briefly
explain the nature of the claim and the parties known to be involved,  and shall
specify the amount  thereof.  If the matter to which a claim  relates  shall not
have been resolved as of the date of the



                                       34

<PAGE>



Claim Notice,  the  Indemnified  Party shall estimate the amount of the claim in
the  Claim  Notice,  but also  specify  therein  that the claim has not yet been
liquidated (an  "Unliquidated  Claim").  If an  Indemnified  Party gives a Claim
Notice for an Unliquidated Claim, the Indemnified Party shall also give a second
Claim Notice (the  "Liquidated  Claim  Notice")  within 60 days after the matter
giving rise to the claim becomes  finally  resolved,  and the  Liquidated  Claim
Notice shall specify the amount of the claim.  Each  Indemnitor to which a Claim
Notice is given shall  respond to any  Indemnified  Party that has given a Claim
Notice (a "Claim  Response")  within 20 days (the  "Response  Period") after the
later of (i) the date that the Claim  Notice is given or (ii) if a Claim  Notice
is first  given with  respect to an  Unliquidated  Claim,  the date on which the
Liquidated  Claim Notice is given.  Any Claim Notice or Claim  Response shall be
given in  accordance  with the  notice  requirements  hereunder,  and any  Claim
Response shall specify  whether or not the Indemnitor  giving the Claim Response
disputes the claim  described in the Claim Notice.  If any  Indemnitor  fails to
give a Claim  Response  within the Response  Period,  such  Indemnitor  shall be
deemed not to dispute the claim  described in the related Claim  Notice.  If any
Indemnitor elects not to dispute a claim described in a Claim Notice, whether by
failing to give a timely Claim  Response or  otherwise,  then the amount of such
claim shall be conclusively deemed to be an obligation of such Indemnitor.

     (b) If any Indemnitor shall be obligated to indemnify an Indemnified  Party
hereunder,  such Indemnitor shall pay to such  Indemnified  Party within 30 days
after  the last day of the  Claim  Response  Period  the  amount  to which  such
Indemnified  Party  shall be  entitled.  If there  shall be a dispute  as to the
amount or manner of indemnification  under this Section 9, the Indemnified Party
may pursue  whatever legal remedies may be available for recovery of the Damages
claimed from any  Indemnitor,  but any dispute  shall be resolved in  accordance
with Section 15 to the extent that it may be applicable. If any Indemnitor fails
to pay  all or  part of any  indemnification  obligation  when  due,  then  such
Indemnitor  Party shall also be obligated to pay to the  applicable  Indemnified
Party  interest on the unpaid  amount for each day during  which the  obligation
remains  unpaid at an annual rate equal to the Prime Rate, and the Prime Rate in
effect on the first  business day of each  calendar  quarter  shall apply to the
amount of the unpaid obligation during such calendar quarter.

     (c) Notwithstanding any other provision of this Section 9, the aggregate of
all Damages  payable by the  Shareholders  under this Section 9 shall not exceed
the Purchase Price (as defined in Section 2.2),  and an Indemnified  Party shall
be entitled to indemnification  hereunder only when the aggregate of all Damages
to such  Indemnified  Party exceeds $50,000 (the  "Deductible  Amount") and then
such Indemnified Party shall be entitled to  indemnification  for its Damages in
excess of the Deductible Amount. The limitations of this paragraph (c), however,
shall not apply to any  covenants or agreements to be performed by an Indemnitor
prior to or after the Closing.  In addition,  the  calculation of the Deductible
Amount shall include any Damages incurred by an Indemnified  Party for which the
Indemnified Party would have been entitled to claim  indemnification  under this
Section 9 with  respect to a breach of  representation  or warranty but for such
representation  or warranty being qualified by  materiality,  the knowledge of a
particular party or related exceptions.

     9.4 Claims Period. Any claim for indemnification under this Section 9 shall
be made by giving a Claim Notice under  Section 9.3 on or before the  applicable
"Expiration  Date"  specified below in this Section 9.4, or the claim under this
Section 9 shall be  invalid.  The  following  claims  shall  have the  following
respective "Expiration Dates": (a) the second anniversary of the Closing



                                       35

<PAGE>



Date--any  claims that are not specified in any of the succeeding  clauses;  (b)
the date on which the applicable  statute of limitations  expires--any claim for
Damages  related to (i) a breach of any covenant or agreement to be performed at
least in part after the Closing Date, or (ii) a breach of any representations or
warranties of a party to this Agreement that relate to Taxes or that were untrue
when  made  with an  actual  intent to  mislead  or  defraud;  and (c) the third
anniversary of the Closing  Date--any claim for Damages related to a breach of a
representation or warranty with respect to an Environmental  Condition.  If more
than one of such Expiration  Dates applies to a particular  claim, the latest of
such Expiration  Dates shall be the controlling  Expiration Date for such claim.
So long as an Indemnified  Party gives a Claim Notice for an Unliquidated  Claim
on or before the applicable  Expiration  Date, such  Indemnified  Party shall be
entitled to pursue its rights to indemnification regardless of the date on which
such Indemnified Party gives the related Liquidated Claim Notice.

     9.5  Third  Party  Claims.  An  Indemnified  Party  that  desires  to  seek
indemnification  under any part of this  Section 9 with  respect to any actions,
suits or other  administrative or judicial  proceedings (each, an "Action") that
may be instituted by a third party shall give each Indemnitor prompt notice of a
third party's institution of such Action. After such notice, any Indemnitor may,
or if so requested by such Indemnified Party, any Indemnitor shall,  participate
in such Action or assume the defense thereof,  with counsel satisfactory to such
Indemnified Party; provided, however, that such Indemnified Party shall have the
right to  participate  at its own  expense in the  defense of such  Action;  and
provided,  further,  that the  Indemnitor  shall not consent to the entry of any
judgment or enter into any  settlement,  except with the written consent of such
Indemnified  Party  (which  consent  shall not be  unreasonably  withheld).  Any
failure  to  give  prompt  notice  under  this  Section  9.5  shall  not  bar an
Indemnified Party's right to claim  indemnification under this Section 9, except
to the extent that an Indemnitor shall have been harmed by such failure.

     9.6  Investigations.   All  covenants,   agreements,   representations  and
warranties made herein or in any agreement,  instrument or certificate delivered
pursuant  to this  Agreement  shall not be  deemed  to be  waived  or  otherwise
affected  by any  investigation  at any time  made by or on  behalf of any party
hereto.

10.  Public Announcements.

     The Selling  Parties and OAOT will consult  with each other before  issuing
any press release or making any public  statement with respect to this Agreement
and the  Transactions  and,  except as may be required by applicable  Law or any
stock exchange regulations, the Selling Parties and OAOT will not issue any such
press release or make any such public statement without the consent of the other
parties hereto.

12.  Amendment, Parties in Interest, Assignment, Etc.

     This Agreement may be amended,  modified or supplemented  only by a written
instrument duly executed by each of the parties hereto. If any provision of this
Agreement shall for any reason be held to be invalid,  illegal, or unenforceable
in any respect,  such  invalidity,  illegality,  or  unenforceability  shall not
affect any other provision  hereof,  and this Agreement shall be construed as if
such  invalid,  illegal or  unenforceable  provision  had never  been  contained
herein.  This Agreement shall be binding upon and inure to the benefit of and be
enforceable  by the  respective  heirs,  legal  representatives,  successors and
permitted  assigns of the parties  hereto.  No party  hereto  shall  assign this
Agreement  or any  right,  benefit or  obligation  hereunder  without  the prior
written  consent of the other  parties  hereto.  Any term or  provision  of this
Agreement may be waived at any time by the party entitled to the benefit thereof
by a written  instrument  duly executed by such party.  The parties hereto shall
execute  and deliver any and all  documents  and take any and all other  actions
that may be deemed reasonably  necessary by their respective counsel to complete
the Transactions.

13.  Interpretation.

     Unless the  context  of this  Agreement  clearly  requires  otherwise,  (a)
references to the plural include the singular, the singular the plural, the part
the whole,  (b) references to any gender  include all genders,  (c) "or" has the
inclusive   meaning   frequently   identified  with  the  phrase  "and/or,"  (d)
"including" has the inclusive meaning frequently identified with the phrase "but
not limited to" and (e)  references to  "hereunder"  or "herein"  relate to this
Agreement.  The section and other  headings  contained in this Agreement are for
reference purposes only and shall not control or affect the construction of this
Agreement or the  interpretation  thereof in any respect.  Section,  subsection,
schedule  and  exhibit   references  are  to  this  Agreement  unless  otherwise
specified.  Each  accounting term used herein that is not  specifically  defined
herein shall have the meaning given to it under GAAP.

14.  Remedies.

     The  indemnification  rights  under  Section  9 are  independent  of and in
addition to such rights and remedies as the parties may have at law or in equity
or otherwise for any misrepresentation, breach of warranty or failure to fulfill
any agreement or covenant  hereunder on the part of any party hereto,  including
the right to seek specific performance, rescission or restitution, none of which
rights or remedies  shall be affected  or  diminished  by Section 9. The parties
shall seek relief, however, under Section 15 for any dispute that is a claim for
Damages, to the extent that Section 15 may apply to such dispute.

15.  Dispute Resolution.

     (a) Good-Faith Negotiations.  If after the Closing any dispute arises under
this Agreement with respect to a claim for Damages that is not settled  promptly
in the ordinary  course of business,  the parties shall seek to resolve any such
dispute  between them,  first,  by negotiating  promptly with each other in good
faith in face-to-face  negotiations.  These  face-to-face  negotiations shall be
conducted by the respective designated senior management  representative of each
party.



                                       37

<PAGE>



If the  parties  are unable to  resolve  such  dispute  between  them  within 20
business  days (or such period as the parties  shall  otherwise  agree)  through
these face-to-face negotiations,  then any such dispute shall be resolved in the
manner set forth in this Section 15.

     (b) Resolution of Disputes.

          (i) Any action,  suit or proceeding based on a claim for Damages where
     the amount in controversy  as to at least one party,  exclusive of interest
     and costs,  exceeds $1,000,000  ("Summary  Proceeding"),  arising out of or
     relating to any Transaction Document or the breach, termination or validity
     thereof,  shall be litigated exclusively in the Superior Court of the State
     of  Delaware  (the  "Delaware  Superior  Court")  as a  summary  proceeding
     pursuant to Rules 124-131 of the Delaware  Superior Court, or any successor
     rules (the "Summary Proceeding  Rules").  Each of the parties hereto hereby
     irrevocably  and  unconditionally  (A) submits to the  jurisdiction  of the
     Delaware  Superior  Court for any  Summary  Proceeding,  (B)  agrees not to
     commence any Summary  Proceeding except in the Delaware Superior Court, (C)
     waives,  and agrees not to plead or to make,  any objection to the venue of
     any Summary  Proceeding in the Delaware  Superior  Court,  (D) waives,  and
     agrees  not to plead or to make,  any  claim  that any  Summary  Proceeding
     brought in the Delaware  Superior  Court has been brought in an improper or
     otherwise  inconvenient  forum,  (E) waives,  and agrees not to plead or to
     make,   any  claim  that  the  Delaware   Superior   Court  lacks  personal
     jurisdiction over it, (F) waives its right to remove any Summary Proceeding
     to the  Federal  courts  except  where such courts are vested with sole and
     exclusive  jurisdiction  by statute and (G)  understands and agrees that it
     shall not seek a jury trial or punitive  damages in any Summary  Proceeding
     based  upon or  arising  out of or  otherwise  related  to any  Transaction
     Document or the breach, termination or validity thereof, and waives any and
     all rights to any such jury trial or to seek punitive damages.

          (ii) If any action,  suit or  proceeding  based on a claim for Damages
     where the  amount in  controversy  as to at least one party,  exclusive  of
     interest and costs, does not exceed $1,000,000 ("Proceeding"),  arising out
     of or relating to any  Transaction  Document or the breach,  termination or
     validity  thereof is brought,  the parties to such Proceeding agree to make
     application  to the Delaware  Superior  Court to proceed  under the Summary
     Proceeding  Rules.  Until such time as such  application is rejected,  such
     Proceeding  shall  be  treated  as a  Summary  Proceeding  and  all  of the
     foregoing  provisions  of this  Section 15 relating to Summary  Proceedings
     shall apply to such Proceeding.

          (iii) If a Summary  Proceeding is not available to resolve any dispute
     hereunder,  the  controversy  or claim  shall  be  settled  by  arbitration
     conducted  on a  confidential  basis,  under  the US  Arbitration  Act,  if
     applicable,  and the  then  current  Commercial  Arbitration  Rules  of the
     American Arbitration Association (the "Association") strictly in accordance
     with the terms of this  Agreement and the  substantive  law of the State of
     Delaware.  The arbitration shall be conducted at the Association's regional
     office located in the Washington,  D.C. area by three arbitrators, at least
     one of whom shall be knowledgeable in the computer and outsourcing services
     industry,  one of whom  shall  be an  attorney  and one of whom  shall be a
     member of a "Big Six" accounting  firm familiar with businesses  engaged in
     software  design,   programming  and  implementation.   Judgment  upon  the
     arbitrators'  award may be entered and  enforced in any court of  competent
     jurisdiction.



                                       38

<PAGE>



     Neither  party shall  institute a proceeding  hereunder  unless at least 60
     days prior thereto such party shall have given written  notice to the other
     party of its intent to do so.

     (c) No party shall be precluded hereby from securing  equitable remedies in
courts  of  any  jurisdiction,   including  temporary   restraining  orders  and
preliminary injunctions to protect its or his rights and interests, but no party
shall seek any such equitable  remedies as a means to avoid or stay  arbitration
or any Summary Proceeding.

                        ADMINISTRATIVE SERVICES AGREEMENT


     THIS  ADMINISTRATIVE  SERVICES AGREEMENT is made as of July 24, 1998 by and
between OAO  Corporation,  a Maryland  corporation  ("OAO"),  and OAO Technology
Solutions, Inc., a Delaware corporation ("OAOT").

                              W I T N E S S E T H:

     WHEREAS, OAOT, OAO, William R. Hill (together with OAO, the "Shareholders")
and OAO  Services,  Inc.  (the  "Company")  have entered  into a Stock  Purchase
Agreement dated as of the date hereof (the "Stock Purchase  Agreement") pursuant
to which OAOT is purchasing all of the outstanding  capital stock of the Company
from the Shareholders (the "Stock Purchase");

     WHEREAS, prior to the Stock Purchase, OAO, as the Company's parent company,
performed certain  administrative  support services for the Company and provided
Benefit Plans (as defined in the Stock Purchase Agreement) for the participation
by certain  employees  and former  employees  of the Company  and  beneficiaries
thereof (the "Company Participants");

     WHEREAS,  OAOT  desires  to retain OAO to  provide  certain  administrative
support  services with respect to the  transition of the business of the Company
to OAOT from OAO;

     WHEREAS,  OAOT  desires OAO to continue  to  maintain  for such  transition
period the Benefits Plans for the participation of the Company Participants; and

     WHEREAS,  OAOT and OAO have agreed to enter into this  Agreement to reflect
the parties' respective rights and obligations.

     NOW,  THEREFORE,  in  consideration of the respective  covenants  contained
herein and  intending to be legally bound  hereby,  the parties  hereto agree as
follows:

     1.  Services.  OAO agrees to continue to provide to the Company  during the
Term (as defined in Section 4) the administrative  support services specified in
Schedule A hereto (the "Services").

     2. Benefits  Continuation.  OAO agrees to continue to maintain and make all
applicable  contributions  under all Benefit Plans for the  participation of the
Company Participants during the Term (the "Benefits Continuation").

     3. Fees and Costs. In  consideration  of the Services to be rendered by OAO
under this  Agreement,  OAOT  shall pay to OAO a monthly  fee of  $100,000  (the
"Services Fee"); provided,  that for any monthly period that is less than a full
month,  such  Services  Fee shall be prorated  for that portion of the month for
which the Services are provided. In consideration of the Benefits




<PAGE>



Continuation  to be  provided  by OAO under this  Agreement  and  subject to the
proviso  hereto,  OAOT shall pay to OAO the costs during the Term (the "Benefits
Costs") of such Employee  Benefits,  including  without  limitation,  applicable
contributions;  provided, however, that OAOT will pay directly for the provision
of any Benefits  Continuation  that is  verifiable  and billed  directly  from a
benefits  provider  or  third  party  other  than OAO  (the  "Separately  Billed
Benefits").  OAO shall provide any invoices for  Separately  Billed  Benefits to
OAOT for  payment  and shall  submit an  invoice to OAOT for  Services  Fees and
Benefits Costs (other than the Separately  Billed  Benefits) on a monthly basis,
the full amount of which shall be due and payable within ten days of the date of
receipt.

     4. Term.  This Agreement shall be effective as of the date hereof and shall
extend  through  and include  (the  "Term") the earlier to occur of (a) the date
upon which OAOT  determines in its sole  discretion  that it no longer  requires
such  Services  and/or  Benefits  Continuation  from OAO and so notifies  OAO in
writing, or (b) December 31, 1998.

     5.  Services  Level.  OAO shall  provide  the same level of  Services as is
consistent  in scope and  quality  with  OAO's  past  practices  regarding  such
services for the Company,  which level is intended by the parties to include, at
a minimum, the assistance of Pamela Conley, the Assistant Controller of OAO, and
the closing of the books of the Company  within the same  monthly and  quarterly
time frames as those used for the closing of the books of OAOT.

     6. Administrative  Liaisons. The person who shall act as the administrative
liaison for OAO shall be Edward Worrell, Senior Vice President.  The persons who
shall  act  as the  administrative  liaisons  for  OAOT  shall  be  Dawn  Byrne,
Controller,  with respect to the Services and Christine Hazel, Vice President of
Human  Resources/Administration,  with respect to the Benefits Continuation. The
parties  shall  communicate  through  such   representatives   with  respect  to
applicable  administrative  matters arising under this  Agreement.  In the event
that an administrative  liaison for a party changes, such party shall notify the
other party in accordance with the notice provisions set forth in Section 8(d).

     7. Relationship of Parties. For purposes of this Agreement and all Services
to be provided  hereunder,  OAO shall not be considered a partner,  co-venturer,
agent or  representative  of the Company or OAOT, but rather shall remain in all
respects an independent  contractor  providing services to the Company and OAOT.
OAO shall not have any right or  authority  to make or  undertake  any  promise,
warranty, or representation, to execute any contract, or otherwise to assume any
obligation or responsibility in the name of or on behalf of the Company or OAOT,
except to the extent specifically authorized herein or in writing by OAOT.

     8. Miscellaneous.

     (a) This Agreement  constitutes  the entire  agreement  between the parties
hereto  with  respect  to the  subject  matter  hereof and may not be amended or
modified except by the written agreement of the parties hereto.

     (b) This  Agreement  shall inure to the benefit of and be binding  upon the
parties  hereto and their  respective  successors.  Nothing  in this  Agreement,
expressed  or implied,  is intended to confer on any other person other than the
parties  hereto,  or  their  respective   successors,   any  rights,   remedies,
obligations or liabilities under or by reason of this Agreement.

     (c) This Agreement and any rights or obligations  pursuant hereto shall not
be assignable  by either party  without the prior  written  consent of the other
