Item 2.           Acquisition or Disposition of Assets.

On June 19, 1998, Advanced  Communication  Systems, Inc., a Delaware corporation
("ACS"),  acquired  all the  outstanding  shares of SEMCOR,  Inc.,  a New Jersey
corporation ("SEMCOR"),  pursuant to a Stock Purchase Agreement, effective as of
June 10,  1998,  by and between ACS and Vincent G. Vidas and John S. Degnan (the
"Shareholders"). The preliminary purchase price of $38 million, which is subject
to adjustment  based on the net equity shown on the closing date balance  sheet,
consisted  of $37  million  in cash  and $1  million  in ACS  common  stock.  In
addition,  ACS may pay  additional  amounts  to the  Shareholders  based  on the
achievement of certain financial goals by SEMCOR for the six-month period ending
December 31, 1998,  and the  twelve-month  period ending  December 31, 1999. ACS
will also pay the  Shareholders  up to $1.25 million for certain tax liabilities
of the  Shareholders  incurred  pursuant to Section  338(h)(10)  of the Internal
Revenue Code. The amount and type of  consideration  was determined on the basis
of negotiations  between ACS and the Shareholders.  ACS financed the acquisition
with proceeds from its revolving credit  facilities with  NationsBank,  N.A. (as
described below).

 On June 19, 1998, ACS increased its existing credit facilities with NationsBank
from $35  million to $45  million to finance  the  acquisition  of SEMCOR and to
provide for its other working  capital needs.  The facilities are secured by all
assets of ACS and its subsidiaries,  including  contract  receivables,  and have
various  financial  covenants which require ACS to maintain  specific  financial
ratios and impose certain  restrictions on, among other things,  the creation or
incurrence of certain  indebtedness,  preferred  stock or liens,  the payment of
dividends,  mergers and the sale of assets,  certain  capital  expenditures  and
certain transactions with and investments in affiliates.

SEMCOR provides a wide range of technical and engineering services, primarily to
the  Department  of  Defense,  in  the  areas  of  communication,  aviation  and
information  technology.  Headquartered in Mt. Laurel, New Jersey, SEMCOR has 42
offices in 24 states and employs more that 1,100 people.

Seller a draft  calculation  of either  the  Initial  Earn Out Period Net Income
Before Taxes or the Second Earn Out Period Net Income Before Taxes,  as the case

nationally  recognized  accounting  firm.  If  either  of the  Sellers  has  any
objection to the Draft Net Income Before Taxes  Calculations,  such Seller shall
deliver a detailed  statement  describing  his objections to the Buyer within 15
days after receiving  either of the Draft Net Income Before Taxes  Calculations.
The Buyer and such  Seller  will use  reasonable  efforts  to  resolve  any such
objections  themselves.  If the Buyer and such Seller do not finally resolve any
of the  objections  within 15 days after the Buyer has received the statement of
objections,  however,  the Buyer and such Seller will  select,  within 5 days, a
nationally  recognized  independent  accounting firm mutually acceptable to each
party  (the  agreement  to the  selection  of which  shall  not be  unreasonably
withheld) to resolve any such  differences  (the  "Arbitrator").  The Arbitrator
shall settle any  remaining  dispute by selecting the position of the party that
the Arbitrator determines,  in its sole discretion,  to be the most correct. The
determination of the Arbitrator shall be set forth in writing, delivered to each
of the Buyer and such Seller and shall be conclusive  and binding on the parties
and shall be  non-appealable.  The party  whose  position  is not  chosen by the
Arbitrator shall pay all expenses of the Arbitrator. The Draft Net Income Before
Taxes  Calculations,  as adjusted for any items of dispute resolved by the Buyer
and the Seller and for any determinations of the Arbitrator shall constitute the
Initial  Earn Out Period Net Income  Before Taxes and the Second Earn Out Period
Net Income Before Taxes, as the case may be.

to an Employee  Pension Benefit Plan  terminating on the date for  determination
and there has been no  "accumulated  funding  deficiency"  or "unfunded  current

investment of the assets of any such  Employee  Benefit Plan (other than routine

                  (a) Until the later of (x) the end of the two (2) year  period
following the Closing Date or (y) two (2) years  subsequent to the date on which
the Sellers' employment with the Company terminates,  each Seller shall not, for
any reason whatsoever, directly or indirectly, for himself or on behalf of or in
conjunction with any other person, persons, company,  partnership,  corporation,
business or other entity of whatever nature:

                           (i) engage,  as a  shareholder,  owner,  partner,  
joint  venturer,  or  in  a  managerial  capacity,  whether  as  an  independent
contractor, consultant or advisor, or as a sales representative, in any business
selling any products or services in direct competition with the current business
of the Company;

                           (ii) call upon any person  who is, at that  time,  an
employee  of the Buyer or the  Company  for the  purpose  or with the  intent of
enticing  such  employee  away  from or out of the  employ  of the  Buyer or the
Company; or

                           (iii)  call upon any  person  or entity  which is, at
that time, or which has been,  within one year prior to that time, a customer of
the  Company for the purpose of  soliciting  or selling  products or services in
competition with the Company.

                  Notwithstanding the above, the foregoing covenant shall not be
deemed to prohibit the Sellers from  acquiring  as an  investment  not more than
five percent (5%) of the capital  stock of a competing  business  whose stock is
traded on a national securities exchange or over-the-counter.

                  (b) Damages.  Because of the difficulty of measuring  economic
losses  to the  Buyer as a result of a breach  of the  foregoing  covenant,  and
because of the  immediate  and  irreparable  damage  that could be caused to the
Buyer for which it would have no other adequate  remedy,  the Sellers agree that
the  foregoing  covenant  may be enforced by the Buyer in the event of breach by
the Sellers, by injunctions and restraining orders.

                  (c) Reasonable Restraint. The Parties agree that the foregoing
covenants in this  Section 5.4 impose a  reasonable  restraint on the Sellers in
light of the  activities  and business of the Buyer on the date of the execution
of this Agreement and the current plans of the Buyer;  but it is also the intent
of the Buyer and the Sellers that such  covenants  be construed  and enforced in
accordance with the changing activities and business of the Buyer throughout the
term of this covenant.  The Parties  further agree that in the event the Sellers
shall enter into a business or pursue other  activities not in competition  with
the Buyer or similar activities or business in locations the operation of which,
under such circumstances, does not violate Section 5.4(a), the Sellers shall not
be chargeable with a violation of this Section 5.4 if the Buyer shall thereafter
enter the same, similar or a competitive (i) business, (ii) course of activities
or (iii) location, as applicable.

                  (d) Severability;  Reformation.  The covenants in this Section
5.4 are  severable  and  separate,  and  the  unenforceability  of any  specific
covenant shall not affect the provisions of any other covenant. Moreover, in the
event any court of competent  jurisdiction  shall determine that the scope, time
or territorial restrictions set forth are unreasonable, then it is the intention
of the Parties that such  restrictions  be enforced to the fullest  extent which
the court deems reasonable, and the Agreement shall thereby be reformed.

                  (e) Independent Covenant. All of the covenants in this Section
5.4 shall be  construed as an agreement  independent  of any other  provision in
this Agreement, and the existence of any claim or cause of action of the Sellers
against the Buyer, whether predicated on this Agreement or otherwise,  shall not
constitute a defense to the  enforcement by the Buyer of such  covenants.  It is
specifically agreed that the period of noncompetition  stated at Section 5.4(a),
during  which the  agreements  and  covenants  of each the Sellers  made in this
Section  5.4  shall be  effective,  shall be  computed  by  excluding  from such
computation  any time during  which such Seller is found by a court of competent
jurisdiction to have been in violation of any provision of this Section 5.4. The
covenants  contained  in Section  5.4 shall not be affected by any breach of any
other  provision  hereof by any  Party  hereto  and shall  have no effect if the
transactions contemplated by this Agreement are not consummated.

                  (f)  Materiality.  The Sellers hereby agree that the covenants
set  forth  in this  Section  5.4 are a  material  and  substantial  part of the
transactions contemplated by this Agreement.

         5.5 Stock Options. Promptly after the Closing, the Buyer shall grant to
certain  employees  of the  Company as  designated  by the  Sellers an option to
purchase  an  aggregate  of  250,000  shares of Common  Stock,  such grant to be
subject to the terms of the Buyer's 1996 Employee Stock  Incentive Plan and 1997
Employee Stock Incentive Plan.

         5.6 Legal Opinions.  At the time of the issuance of Common Stock to the
Sellers  hereunder,  the Buyer will deliver an opinion of counsel to the Sellers
reasonably satisfactory to the Sellers.

7.       REMEDIES FOR BREACHES OF THIS AGREEMENT.

         7.1 Survival of Representations and Warranties.  Except with respect to
Sections 3.1(a),  3.1(d),  4.1, 4.2, 4.10, 4.23,  Government Contract Claims (as
defined herein) or 4.26, all  representations  and warranties  contained in this
Agreement,  including  those  contained  in the  exhibits,  schedules  and other
documents delivered pursuant to this Agreement,  above shall survive the Closing
hereunder  and  continue in full force and effect until  December 31, 1999.  All
covenants  contained in this Agreement  likewise shall survive the Closing,  but
shall not be subject to the  limitation  on survival set forth in the  preceding
sentence.  Representations  and  warranties  contained  in  Section  4.25 or any
representation  or  warranty  relating  to a  Government  Contract  ("Government
Contract  Claims")  shall  survive  Closing  and shall  remain in full force and
effect for a period of six (6) years.  Representations and warranties  contained
in Section 4.26 shall survive  Closing and shall remain in full force and effect
for a period of five (5) years.  Representations  and  warranties  contained  in
Sections 3.1(a),  3.1(d),  4.1, 4.2, 4.10, 4.23, shall survive Closing and shall
remain in full force and effect until the  expiration of applicable  statutes of
limitation.  So long as a claim arising out of a breach of a  representation  or
warranty is made prior to the  expiration  of such  representation  or warranty,
indemnification  may be had (subject to the other  provisions of this Section 7)
notwithstanding  that the  scope of loss may not be  determined,  remedial  work
completed or claim otherwise resolved prior to such expiration.

         7.2  Indemnity.  Each Party  hereto (the  "Indemnifying  Party")  shall
indemnify  and hold the  other  Party  hereto  (each,  an  "Indemnified  Party")
harmless to the extent  provided in this  Section 7 from and against any and all
losses (consequential or otherwise), Liabilities, claims, disputes, proceedings,
demands,  cost unallowability  determinations,  judgments,  settlements,  liens,
costs and  expenses  of any nature  whatsoever  (including  reasonable  fees and
disbursements of attorneys, accountants, or other professional advisors relating
to investigation, prosecution, negotiation, defense, settlement, or appeal) (the
foregoing referred to individually as an "Adverse  Consequence" and collectively
as "Adverse Consequences") resulting from or arising out of:

         (i) any breach of any  representation  or warranty of the  Indemnifying
Party  contained in this  Agreement or in any  schedule,  exhibit,  certificate,
document   or  other  item   delivered   by  the   Indemnifying   Party  or  its
representative(s) in connection with this Agreement;

         (ii) the  nonperformance,  partial or total, of any covenant (including
the covenants and obligations set forth in Article 8, below) of the Indemnifying
Party contained in this Agreement;

         (iii) the scheduled items set forth on Schedules 4.9, 4.19 and 4.25;and

         (iv)  any  and  all  Adverse  Consequences  incidental  to  any  of the
foregoing  or to the  enforcement  of this  Section  7.2.  Without  limiting the
foregoing,  the Sellers'  indemnification  liabilities arising from Section 4 of
this  Agreement  shall include  Adverse  Consequences  consisting of any and all
Taxes of the Company with  respect to any period (or any portion  thereof) up to
and including  the Closing  Date,  except for Taxes of the Company (if any) that
are  reflected  as  current or  deferred  liabilities  for Taxes on the  Interim
Balance  Sheet Date.  Each Seller  hereby agrees that he will not make any claim
for  indemnification  against  the  Company  by reason of the fact that he was a
director,  officer,  employee,  or agent of the  Company  or was  serving at the
request of the Company as a partner, trustee,  director,  officer,  employee, or
agent  of  another  entity  (whether  such  claim  is  for  judgments,  damages,
penalties,  fines,  costs,  amounts paid in  settlement,  losses,  expenses,  or
otherwise and whether such claim is pursuant to any statute,  charter  document,
bylaw,  agreement,  or otherwise)  prior to the Closing Date with respect to any
action,  suit,  proceeding,  complaint,  claim,  or demand  brought by the Buyer
against the Sellers (whether such action, suit, proceeding, complaint, claim, or
demand is pursuant to this Agreement, applicable law, or otherwise).

         7.3      Notice of Claim.

         (a) If an  Indemnified  Party makes any claim  against an  Indemnifying
Party for  indemnification,  such claim  shall be in writing  and shall state in
general terms the facts upon which the Indemnified Party makes such claim.

         (b)  In  the  event  of  any  claim  or  demand  asserted  against  the
Indemnified  Party by a third party upon which the  Indemnified  Party may claim
indemnification,  the  Indemnifying  Party  shall  give  written  notice  to the
Indemnified  Party within 15 days after  receipt of notice from the  Indemnified
Party indicating whether the Indemnifying Party intends to assume the defense of
such claim or demand.  If the  Indemnifying  Party does assume such defense,  it
shall indemnify and hold the Indemnified Party harmless from and against any and
all losses,  damages and liabilities  caused by or arising out of any settlement
or  judgment  of such  claim  and  may  not  claim  that  it  does  not  have an
indemnification   obligation   with  respect   thereto.   Notwithstanding   such
assumption,  the  Indemnified  Party shall have the right to participate in such
defense,  by written notice given to the Indemnifying  Party within 15 days from
the date of the Indemnifying  Party's notice,  provided that such  participation
shall be at the expense of the  Indemnified  Party unless there is a conflict of
interest between the Indemnified Party and the Indemnifying Party, in which case
the cost of such participation  (including  attorneys' fees for counsel selected
by the Indemnified Party) shall be reimbursed by the Indemnifying  Party. If the
Indemnifying  Party assumes the defense and the Indemnified  Party elects not to
participate, the Indemnifying Party shall have the right fully to control and to
settle the proceeding.  If the  Indemnified  Party elects to participate in such
defense, the parties shall cooperate in the defense of the proceeding, and shall
not settle the same  without the  consent of each,  which  consent  shall not be
unreasonably withheld or delayed. If the Indemnifying Party elects not to assume
the defense, the Indemnified Party shall have the right to do so (at the expense
of the Indemnifying  Party),  and may settle the same without the consent of the
Indemnifying Party.

         (c)  In  the  event  an  Indemnified  Party  has  a  claim  against  an
Indemnifying  Party  hereunder  which does not  involve a claim  being  asserted
against or sought to be collected by a third party, the Indemnifying Party shall
give written  notice to the  Indemnified  Party within 15 days after  receipt of
notice from the Indemnified  Party  indicating  whether the  Indemnifying  Party
disputes such claim. If the  Indemnifying  Party does not notify the Indemnified
Party within such 15 day period that the Indemnifying Party disputes such claim,
the  amount  of such  claim  shall be  conclusively  deemed a  liability  of the
Indemnifying  Party hereunder.  In the event that the  Indemnifying  Party shall
object in writing to any claim made in accordance with this Section 7.3(c),  the
Indemnified  Party shall have 15 days to respond in a written  statement  to the
objection of the Indemnifying Party. If after such 15 day period there remains a
dispute as to any claims, the Parties shall attempt in good faith for 30 days to
agree upon the rights of the  respective  Parties  with  respect to each of such
claims.  If the  Parties  should so  agree,  a  memorandum  setting  forth  such
agreement  shall be prepared  and signed by all Parties.  If the Parties  cannot
agree  within such 30 day  period,  the Parties  shall  jointly  select a single
arbitrator (the "Indemnification  Arbitrator"),  the selection of which will not
be unreasonably withheld by either Party, who shall have substantial  experience
with  respect to the  substance  of the  matters  in dispute  and shall have the
authority  to hold  hearings  and to render a decision  in  accordance  with the
arbitration rules of the American Arbitration  Association.  The Indemnification
Arbitrator  shall settle any remaining  dispute by selecting the position of the
Party that the Arbitrator  determines,  in its sole  discretion,  to be the most
correct. The determination of the Indemnification  Arbitrator shall be set forth
in  writing,  delivered  to each of the  Buyer  and the  Sellers  and  shall  be
conclusive  and binding on the Parties  and shall be  non-appealable.  The Party
whose  position is not chosen by the  Indemnification  Arbitrator  shall pay all
expenses of the Indemnification Arbitrator.

         7.4  Limitation.   Notwithstanding   the  above,  and  except  for  (i)
misrepresentations  and breaches of  warranties  by the Sellers  under  Sections
3.1(a),  3.1(d), 4.1, 4.2, 4.10, 4.23, 4.26, (ii) and (iii) Adverse Consequences
resulting from or arising out of the scheduled  items set forth on Schedule 4.9,
4.19 and 4.25(i), the Sellers shall not be liable under this Section 7 (y) until
the aggregate  amount of Adverse  Consequences in respect of  misrepresentations
and breaches of warranties to the Buyer exceeds $300,000, and only to the extent
of such excess, and (z) to the extent that the Adverse Consequences to the Buyer
exceeds $20,000,000.

         7.5 Indemnity Fund. The Buyer shall withhold from the Purchase Price an
indemnity  fund in the amount of $5,000,000 in the form of cash and Common Stock
as set forth in Section 2.2 (the  "Indemnity  Fund") as a hold-back  in order to
provide a fund for the payment of any  Adverse  Consequences  resulting  from or
arising out of (i) the scheduled items set forth on Schedule 4.9, 4.19 and 4.25,
(ii) any breach of any  representation  or warranty of the Sellers  contained in
this Agreement or in any schedule, exhibit, certificate,  document or other item
delivered by the Sellers or (iii) any  payments  required to be made to Buyer in
accordance  with Section 2.5,  above.  Any payments made from the Indemnity Fund
shall first reduce the number of shares of the Buyer's  common stock held within
the Indemnity  Fund,  such shares being valued at the same value as set forth in
Section  2.2  herein,  and then shall  reduce the amount of cash held within the
Indemnity  Fund. No interest shall accrue on any funds held within the Indemnity
Fund.  Any  dividends  received by the Buyer with  respect to Common  Stock held
within  the  Indemnity  Fund  shall  be  retained  by the  Buyer  as part of the
Indemnity Fund and released to the Sellers in accordance  with the terms of this
Section 7.5. The Indemnity Fund shall be retained by the Buyer until the earlier
of three  business  days after  delivery of the Closing  Date  Balance  Sheet in
accordance  with Section 2.5 or ninety days  subsequent to the Closing Date (the
"Release  Date").  If after the  Release  Date,  the  Buyer  has no  claims  for
indemnification  pending,  then the Buyer shall pay to the Sellers the Indemnity
Fund.  If the  Buyer  has any  claims  for  indemnification  pending,  any funds
reasonably  necessary  to satisfy  such  claims  shall be  retained by the Buyer
pending final resolution of such claims,  at which point the Buyer shall pay the
balance,  if any,  remaining in the Indemnity Fund, to the Sellers.  The Sellers
and  the  Buyer   expressly   acknowledge   that  if  the  Buyer's   claims  for
indemnification  for breaches of representations or warranties exceed the amount
of such  Indemnity  Fund, the Sellers and their  successors  and assigns,  shall
remain liable for any such excess in accordance with this Section 7.

         7.6 Recoupment. The Buyer shall have the option of recouping all or any
part  of any  Adverse  Consequences  it may  suffer  (in  lieu  of  seeking  any
indemnification  to which it is entitled  under this Section 7) by notifying the
Sellers within 30 days after the end of the applicable  Earn Out Period that the
Buyer is reducing the amount of any Contingent  Purchase Price otherwise payable
to the Sellers. The written notice shall specify the general,  factual basis for
such claim and the amount the Contingent  Purchase  Price is to be reduced.  The
Buyer shall pay the remainder of the Contingent Purchase Price not recouped.  If
the Sellers have any objection to the reduction,  the Sellers shall have 30 days
to make  such  investigation  of the claim as the  Sellers  deems  necessary  or
desirable.  For the  purposes of such  investigation,  the Buyer  agrees to make
available to the Sellers or their  authorized  representatives  the  information
relied upon by Buyer to substantiate the reduction.  If the Buyer and Sellers do
not  agree  within  such  30 day  period,  the  matter  shall  be  submitted  to
arbitration in accordance with the arbitration rules of the American Arbitration
Association then in effect. Within such 30 day period, the parties shall jointly
select a single arbitrator (the "Recoupment Arbitrator"), the selection of which
will not be unreasonably  withheld by either party,  who shall have  substantial
experience  with  respect to the  substance  of the matters in dispute and shall
have the authority to hold hearings and to render a decision in accordance  with
the arbitration rules of the American  Arbitration  Association.  The Recoupment
Arbitrator  shall settle any remaining  dispute by selecting the position of the
party that the Arbitrator  determines,  in its sole  discretion,  to be the most
correct.  The  determination of the Recoupment  Arbitrator shall be set forth in
writing,  delivered to each of the Buyer and the Sellers and shall be conclusive
and binding on the parties and shall be non-appealable. The party whose position
is not  chosen  by the  Recoupment  Arbitrator  shall  pay all  expenses  of the
Recoupment  Arbitrator and interest accruing on the amount of reduction,  at the
rate of the regular  commercial  prime rate of interest that  NationsBank,  N.A.
uses as a standard for  determining  actual  interest  rates charged  commercial
borrowers, beginning on the date the Contingent Purchase Price was otherwise due
to be paid to the Sellers.


8.       TAX MATTERS.

         The following  provisions shall govern the allocation of responsibility
as between the Buyer and the Sellers  for  certain  tax  matters  following  the
Closing Date:

         8.1      Section 338(h)(10) Election.

                  (a) The Sellers  agree,  if so directed by the Buyer,  to join
with the Buyer in making an  election  under Code  section  338(h)(10)  (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 the
Company Shares.

                  (b) The Sellers shall pay (i) any Tax, including any liability
of the  Company  for any Tax  resulting  from  application  to it of  applicable
regulations,  attributable to the making of the Section 338(h)(10)  Election and
will  indemnify  the Buyer and the  Company  against  any  Adverse  Consequences
arising out of any failure to pay such Tax and (ii) any state,  local or foreign
Tax (and  indemnify the Buyer and the Company  against any Adverse  Consequences
arising out of any failure to pay such Tax)  attributable  to an election  under
state,  local or foreign law similar to the  election  available  under  Section
338(h)(10)  of the Code (or which  results from the making of an election  under
Section  338(h)(10)  of the Code) with  respect to the  purchase and sale of the
Company hereunder, provided, however, that the Buyers will pay to the Sellers up
to an  aggregate  amount of  $1,250,000  pursuant  to  Section  2.2 above to the
Sellers  for  any Tax  attributable  to the  making  of the  Section  338(h)(10)
election,  including any income Tax liability of the Sellers attributable to the
Company  electing to convert from a cash to an accrual  method of accounting for
federal  income tax  purposes,  such  election  being  effective for the federal
taxable  year  ending on the  Closing  Date,  to the extent that such income Tax
exceeds the income Tax for which the Sellers would otherwise have been liable if
the Sellers had sold their Company  Shares without making any such election (the
"338(h)(10) Tax  Liability").  The Sellers will be liable for any Tax due on any
payments made by the Buyer to the Sellers pursuant to this Section 8.1(b).

         8.2 Tax Periods Ending on or Before the Closing Date. The Sellers 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 Date that are
filed after the Closing  Date.  The Sellers shall permit the Buyer to review and
comment on each such Tax Return  described in the  preceding  sentence  prior to
filing.  Sellers  shall  pay any  Taxes  shown on any such Tax  Returns.  As the
shareholders  of an S  corporation,  except for amounts  reserved on the Closing
Date Balance Sheet,  the Sellers will pay and discharge and be  responsible  for
any and all Taxes due or  payable  by the  Sellers  and by the  Company  for any
taxable year or taxable  period ending on or before the Closing Date  including,
without limitation, any liability that the Sellers may owe as individuals in any
jurisdiction  in which the Company is treated as an S corporation.  In addition,
the  Sellers  will pay and  discharge  and be  responsible  for any state  taxes
(including without limitation, excise and franchise taxes) due or payable by the
Company for any taxable year or taxable  period  ending on or before the Closing
Date,  including without  limitation,  any liability that the Sellers may owe as
individuals  in any  jurisdiction  in  which  the  Company  is  treated  as an S
corporation.

         8.3  Allocation  of  Purchase  Price.  Within 30 days after the Closing
Date,  the Buyer shall deliver to the Sellers a draft  schedule  allocating  the
Purchase  Price and the  liabilities  of the  Company  among  the  assets of the
Company for all purposes  (including  Tax and financial  accounting) in a manner
consistent with the fair market values of such assets (the "Draft Purchase Price
Allocation").  If the Sellers  have any  objection to the Draft  Purchase  Price
Allocation,  the Sellers shall  deliver a detailed  statement  describing  their
objections to the Buyer within 5 days after  receiving the Draft  Purchase Price
Allocation. The Buyer and the Sellers will use reasonable efforts to resolve any
such objections themselves.  If the Buyer and Sellers do not finally resolve any
of the  objections  within 5 days after the Buyer has received the  statement of
objections,  however,  the Buyer and the Sellers will  select,  within 5 days, a
nationally  recognized  independent  accounting firm mutually acceptable to each
Party, the agreement to the selection which shall not be unreasonably  withheld,
to resolve any such differences (the "Arbitrator").  The Arbitrator shall settle
any remaining dispute by selecting the position of the Party that the Arbitrator
determines, in its sole discretion, to be the most correct. The determination of
the Arbitrator shall be set forth in writing, delivered to each of the Buyer and
the  Sellers  and shall be  conclusive  and  binding on the Parties and shall be
non-appealable.  The Party whose position is not chosen by the Arbitrator  shall
pay all expenses of the  Arbitrator.  The Draft  Purchase Price  Allocation,  as
adjusted for any items of dispute  resolved by the Buyer and the Sellers and for
any  determinations  of the Arbitrator shall be referred to herein as the "Final
Purchase Price  Allocation." The Buyer and the Sellers will file and the Sellers
will cause the Company to file all Tax Returns  (including  amended  returns and
claims for refund) and information reports in a manner consistent with the Final
Purchase Price Allocation.

         8.4 S Corporation  Status. The Sellers will not, and will not allow the
Company to, revoke the Company's election to be taxed as an S corporation within
the meaning of Code sections  1361 and 1362.  The Sellers will not, and will not
allow  the  Company  to,  take or allow  any  action  that  would  result in the
termination of the Company's status as a validly  existing S corporation  within
the meaning of Code sections 1361 and 1362.

         8.5 Tax Periods Beginning Before and Ending After the Closing Date. The
Buyer shall  prepare,  or cause to be prepared,  and file, or cause to be filed,
any Tax Returns of the Company  for Tax periods  which begin  before the Closing
Date and end after the  Closing  Date.  The Buyer  shall  permit the  Sellers to
review and comment upon each such Tax Return described in the preceding sentence
prior to filing.  The Sellers  shall pay to the Buyer  within  fifteen (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 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 face of the Closing Date Balance Sheet. For purposes of this Section, 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 Date, the portion
of such Tax which  relates to the portion of such Taxable  period  ending on the
Closing  Date shall (x) 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  Date  and the
denominator  of which is the number of days in the entire Taxable period and (y)
in the case of any Tax based  upon or related  to income or  receipts  be deemed
equal to the amount which would be payable if the relevant  Taxable period ended
on the Closing Date. Any credits relating to a Taxable period that begins before
and ends  after the  Closing  Date  shall be taken  into  account  as though the
relevant Taxable period ended on the Closing Date. All determinations  necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of the Company .

         8.6      Cooperation on Tax Matters.

                  (a) The Buyer and the Sellers  shall,  and the  Sellers  shall
cause the Company to, 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 8 and any audit,  litigation  or other  proceeding  with respect to
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.  The Parties 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 Date (except those books and records
in the  custody  of  the  Company)  until  the  expiration  of  the  statute  of
limitations  (and, to the extent notified by Buyer,  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  requested,  allowing  the other Party to take
possession of such books and records.

                  (b) Buyer and Sellers  further  agree,  upon  request,  to use
their  best  efforts  to  obtain  any  certificate  or other  document  from any
Governmental Entity 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).

                  (c) Buyer and Sellers further agree, upon request,  to provide
the other Party with all information that either Party may be required to report
pursuant to Section  6043 of the Code and all  Treasury  Department  Regulations
promulgated thereunder.

9.       MISCELLANEOUS.

         9.1   Cooperation.   The  Sellers   and  the  Buyer,   for  no  further
consideration,  shall each  deliver or cause to be delivered to the other on the
Closing Date, and after the Closing Date at such other times and places as shall
be reasonably agreed to, such additional instruments as the other may reasonably
request for the purpose of carrying out this Agreement. In connection therewith,
if  required,  the  President  or Chief  Financial  Officer of the Company  will
execute any documentation  reasonably required by the Buyer's independent public
accountants (in connection with such  accountant's  audit of the Company) or the
Nasdaq National Market.  Without  limitation of the foregoing,  the Sellers will
cooperate  and use  their  reasonable  efforts  to cause the  Company's  present
officers,  directors  and employees to cooperate  with the Buyer before,  on and
after the Closing Date in furnishing information,  evidence, testimony and other
assistance  in  connection  with  any,  actions,  proceedings,  arrangements  or
disputes of any nature with respect to matters  pertaining  to all periods prior
to the Closing Date and the Buyer will cooperate and use its reasonable  efforts
to cause its  present  officers,  directors  and  employees  cooperate  with the
Sellers before, on and after the Closing Date in furnishing any such information
to employees of the Sellers and/or the Company who will be continuing employment
with the Company after the sale,  regarding such continued  employment.  Without
limitation of the foregoing,  in connection with any securities  filing required
of the Buyer as a result of the Purchase, (i) the Sellers will cooperate and use
their reasonable  efforts to assist the Buyer and the Company in the preparation
of audited and unaudited (as required) financial  statements for the Company and
(ii) the  Sellers  will use their  reasonable  efforts  to cause  the  Company's
accountants  at the Buyer's sole cost and  expense,  to assist the Buyer and the
Company in the preparation of such financial statements.

         9.2  Successors  and  Assigns.  This  Agreement  and the  rights of the
Parties  hereunder may not be assigned (except by operation of law) and shall be
binding  upon  and  shall  inure  to the  benefit  of the  Parties  hereto,  the
successors of the Buyer, and the heirs and legal representatives of the Sellers.

         SECTION 5.   AFFIRMATIVE COVENANTS


                  The Borrowers hereby jointly and severally agree that:




         1.10.  SEMCOR/Loan  Party.  The  requirements of subsection 7.12 of the
Credit  Agreement  with  respect to SEMCOR  shall have been  satisfied as of the
close of business on the Acquisition Date.


         1.11.  Assignments  of  Government  Receivables.  The  Borrowers  shall
execute and deliver to the Agent, for the benefit of the Lenders,  within thirty
(30) days after the Acquisition Date, all statements of assignment,  in form and
substance  satisfactory to the Agent, which are deemed necessary by the Agent in
connection  with the  assignment to the Agent by the Borrowers of the Government
Receivables of SEMCOR that arise under Government  Contracts  existing as of the
Acquisition Date, provided,  however that the Borrowers shall not be required to
execute and deliver such  statements  of  assignment  and/or  notification  with
respect to Government Receivables of SEMCOR that arise (i) under a contract with
a maximum ceiling value of $500,000 or less or (ii) under a contract  (including
all options,  extensions and other like provisions with respect  thereto) of six
(6) months or less remaining in duration as of the Acquisition Date. The failure
by the Borrowers to assign such  Government  Receivables  will be deemed to be a
default under Section 9(c) of the Credit Agreement.


         1.12. Representations of SEMCOR.  Notwithstanding anything contained in
the Credit  Agreement,  the Joinder  Agreement or any other Loan Document to the
contrary:


         (a) for the  period  from the date  hereof  until the  delivery  of the
Officer's  Certificate  described in paragraph  (c) hereof,  SEMCOR shall not be
deemed to make any  representation  contained  in the  Credit  Agreement  or the
Security Agreement;


         (b) the  Borrowers  hereby  represent and warrant to the Agent and each
Lender that each of the  representations  and warranties made by the Seller with
respect to the  "Company"  (as  therein  defined) in the SEMCOR  Stock  Purchase
Agreement are true and correct on and as of the date hereof;


         (c) on or before the thirtieth  (30th) day after the Acquisition  Date,
SEMCOR shall deliver to the Agent and the Lenders a certificate of a Responsible
Officer of SEMCOR  certifying  that each of the  representations  and warranties
made by SEMCOR,  as a Borrower under the Credit Agreement and under the Security
Agreement,  are true and correct in all material  respects on and as of the date
of such certificate;


         (d) the  failure  of SEMCOR to deliver  the  certificate  described  in
paragraph  (c) shall be an Event of  Default  under  Section  9(c) of the Credit
Agreement.


         1.13.  General  Information.  The Agent shall have  received such other
opinions or documents as the Agent or the Majority Lenders through the Agent may
reasonably request.


         SECTION 6.   FINANCIAL COVENANTS


                  The Borrowers hereby jointly and severally agree that:




         1.14. Debt.  Notwithstanding anything contained in the Credit Agreement
or any other Loan  Document  to the  contrary,  for the  purpose of  determining
compliance  with  the  negative  covenant  contained  in  8.1(a)  of the  Credit
Agreement,  for any fiscal period,  only seventy-five  percent (75%) of deferred
purchase  price of property or services  with  respect to SEMCOR for such period
shall be included in the  calculation  of Debt  provided that if as of March 31,
1999 and/or the last day of any fiscal quarter thereafter,  the EBITDA of SEMCOR
would on an  annualized  pro forma basis equal EBITDA as of the Initial Earn Out
Period (as defined in the SEMCOR Stock  Purchase  Agreement) or EBITDA as of the
Second Earn Out Period (as defined in the SEMCOR Stock Purchase  Agreement) then
one  hundred  percent  (100%) of the  deferred  purchase  price of  property  or
services  with  respect  to SEMCOR  for each  such  period  thereafter  shall be
included in the calculation of Debt.


         1.15.  EBIDA/EBITDA.  Notwithstanding  anything contained in the Credit
Agreement  or any other  Loan  Document  to the  contrary,  for the  purpose  of
determining  compliance  with the  negative  covenants  contained  in 8.1(a) and
8.1(b) of the Credit Agreement,  for any fiscal period from March 31, 1998 until
and including  March 31, 1999,  the  following  amounts shall be restored to the
Consolidated  Net Income or  Consolidated  Net Loss,  as the case may be, in the
calculation  of EBIDA and EBITDA for ACS Inc.:  (i) the amount  attributable  to
payments  to a former  shareholder  of SEMCOR  which is set forth  opposite  the
caption  "payments  to  former   stockholder"  (or  any  like  caption)  on  the
consolidating  income  statement  of ACS  Inc.,  to the  extent  such  amount is
incurred  prior to the  Acquisition  Date, and (ii) the amount  attributable  to
SEMCOR  owners'  salaries in excess of the DCAA  allowable  amount  which is set
forth opposite the caption  "amount paid to owners over DCAA  allowable" (or any
like caption) on the  consolidating  income statement of ACS Inc., to the extent
such amount is incurred prior to the Acquisition Date.
