     officer and  director  of both ISI and CSI.  See Section 8, pages 17 and 18
     for more information.

            WHAT ARE THE CLASSES AND AMOUNTS OF SECURITIES SOUGHT IN THE OFFER?

     We are  offering to purchase  all of the  outstanding  Common  Shares.  See
     "Introduction" and Section 1, pages 7 through 9 for further details.

   HOW MUCH ARE YOU OFFERING TO PAY, WHAT IS THE FORM OF PAYMENT AND WILL I HAVE
TO PAY ANY FEES OR COMMISSIONS?

     We are offering to pay $1.00 per Common Share,  net to you, in cash. If you
     are the record  owner of your  Common  Shares and you  tender  your  Common
     Shares  to us in the  Offer,  you will not  have to pay  brokerage  fees or
     similar  expenses.  If you own your Common Shares through a broker or other
     nominee,  and your broker  tenders your Common Shares on your behalf,  your
     broker or nominee  may  charge  you a fee for doing so. You should  consult
     your broker or nominee to  determine  whether any charges  will apply.  See
     "Introduction" for further information.

     2000 to tender  your  Common  Shares in the Offer.  Further,  if you cannot

              If you wish to accept the Offer, you must do the following:

     - If you are a record holder (i.e., a stock  certificate has been issued to
     you), you must either  complete and sign the enclosed letter of transmittal
     and send it with your stock  certificate  to the  depositary for the Offer,
     Continental  Stock  Transfer  & Trust  Company,  or follow  the  procedures
     described in this document for book-entry  transfer.  These  materials must
     reach the depositary  before the Offer expires.  Detailed  instructions are
     contained in the letter of  transmittal  and on pages 10 through 13 of this
     document.

     - If you are a record holder but your stock certificate is not available or
     you cannot deliver it to the depositary  before the offer expires,  you may
     be able  to  tender  your  Common  Shares  using  the  enclosed  notice  of

     agent  for the  Offer,  at  800-928-0153  for  assistance.  See page 12 for
     further details.

     - If you hold your  Common  Shares  through a broker  or bank,  you  should
     instruct your broker or bank totender  your Common  Shares.  See Section 3,
     pages 10 through 13 for further details.

                  CAN I WITHDRAW MY PREVIOUSLY TENDERED SHARES?

     If, after tendering your Common Shares in the Offer, you decide that you do
     NOT want to accept the Offer,  you can  withdraw  your Common  Shares by so
     instructing  the depositary  before the Offer  expires.  If you tendered by
     giving  instructions  to a broker or bank,  you must instruct the broker or
     bank to arrange for the  withdrawal of your Common  Shares.  See Section 4,
     page 14 for further details.

            WHAT DOES THE COMPANY'S BOARD OF DIRECTORS THINK OF THE OFFER?

     The  Company's  Board  of  Directors  has  determined  that,  based  on the
     Company's  current financial  condition,  its inability to obtain financing
     for  its  operations,   which  could  result  in  the  Company  filing  for
     bankruptcy,  recent bid prices  for the Common  Shares on the OTC  Bulletin
     Board  and the  Company's  current  book  value,  the  Offer is in the best
     interests of the Company and its  stockholders,  and has voted to recommend
     to theCompany  stockholders acceptance of the Offer. The Company's Board of
     Directors  recommends that Company  stockholders tender their shares in the
     Offer. See "Introduction" for further details.

                   WILL THERE BE A SUBSEQUENT OFFERING PERIOD?

- - We may give stockholders who do not tender in the Offer another opportunity to
tender at the same price in a subsequent  offering period. See Section 1, page 9
for further details.

     - The subsequent offering period, if any, will begin on the day we announce
     that we have purchased  Common Shares in the Offer and last for three to 20
     business days. We may extend the subsequent offering period,but it will not
     last more than 20 business days in total. See Section 1, page 9 for further
     details.

     - There will be no withdrawal rights in the subsequent offering period. See
       Section  1, page 9 for further details.

               WHAT IS THE VALUE OF MY SHARES AS OF A RECENT DATE?

     - The average of the  closing  bid prices for Common  Shares as reported on
     the OTC Bulletin  Board over the 20 trading days  immediately  prior to the
     date before we publicly announced on April 26, 2000 the Offe to acquire the
     Common  Shares  was $0.84 per  Common  Share.  See  Section  5, page 15 for
     further information.

         -        The  closing  bid  price  for  the  Common  Shares  on the OTC
                  Bulletin  Board was $0.72 per Common  Share on April 24, 2000,
                  two  trading  days  before we  announced  the Offer to acquire
                  Common Shares.

     - The current book value of the Company is $1,248,485,  or $0.33 per Common
     Share; the current liquidation value of the Company,  which is negative, is
     approximately  $(1.00) per Common Share; market prices of the Common Shares
     over the past 90 days ranged between $0.72 and $1.00 per Common Share;  and
     Common Shares have only traded on 25 out of the past 60 trading  days,  and
     during such period,  the total number of Common Shares  traded  amounted to
     less than one-half of 1%of the total outstanding Common Shares. See Section
     5, page 15 for more information.

        - Before deciding whether to tender,  you should obtain a current market
quotation for the Common Shares.

             WHO CAN I TALK TO IF I HAVE QUESTIONS ABOUT THE OFFER?

If you have  questions  about the offer or  require  additional  information  or
assistance,  you can call our  information  agent,  D.F.  King & Co.,  Inc.,  at

RESPECT TO THE OFFER.

                                 SPECIAL FACTORS

I.          BACKGROUND OF THE OFFER

           The Company  commenced  operations in 1994 and has operated at a loss
  every year since 1996.  In 1997, in an effort to rebound from its 1996 losses,
  the Company began to implement a strategy of growth and acquisition

     that  its  Board  of  Directors  anticipated  would  expand  the  Company's
     technological  expertise and customer base. As part of this  strategy,  the
     Company  acquired  three  computer  services  companies,   Cintronix,  Inc.
     ("Cintronix"), Advanced Network Systems and Phoenix Service, Inc. ("Phoenix
     Service") in 1997. The Company's management had

     hoped that the acquisitions of Cintronix and Advanced Network Systems would
 further the Company's goal of developing regional clusters of sales and service
 representatives to improve customer service and to gain greater

     market penetration.  The expected integration of these two acquisitions and
     the projected  increase in marketing and decrease in costs due to economies
     of scale failed to occur during 1998. Only the Phoenix Service acquisition

     provided  significant  expansion  in growing the  Company's  customer  base
     profitably. As a result of the poor performance of the two acquisitions, in
     1998 the Company took a one-time  charge of  approximately  $1.7 million to
     write  down  the  carrying  value  of  the  acquired  companies  due to the
     impairment of the related assets, primarily goodwill.

          On May 19,  1998,  the Company was notified by the Nasdaq Stock Market
   that the Common Shares,  which were traded on the SmallCap Market, had failed
   to maintain a closing bid price greater than or equal to $1.00 per

Common  Share.  Although  the Company was granted a temporary  exception  to the
minimum bid price  requirement,  the requirement was still not met by the end of
the exception period,  August 18, 1998. The Common Shares were delisted from the
SmallCap Market on August 24, 1998.

In an effort to provide  liquidity  for its  shareholders  during this period of
financial  downturn,  in June 1998 the Company contacted Ferris,  Baker,  Watts,
Incorporated  ("Ferris  Baker")  regarding a potential  merger of the Company or
sale of all or part of the Common Shares. On June 23,  1998,after  negotiations,
the  Company  retained  Ferris  Baker  as its  financial  advisor  to  seek  out
prospective  purchasers  and to assist  the  Company  inthe  negotiation  of any
proposed transactions.

     Over the  course of the  ensuing  12  months,  Ferris  Baker  contacted  25
     prospective  buyers in the computer hardware  industry,  including Decision
     One,  Anacomp,  STK,  Amdahl  and  Unisys.  While  many of the  prospective
     candidates that were approached  responded  favorably upon  initialcontact,
     none of the negotiations  materialized  into an offer for the Common Shares
     or the Company's assets.

            After the termination of the contract with Ferris Baker, the Company
 made further  attempts from July 1999 to February  2000 to pursue  transactions
 that  would  provide  its   shareholders   with   liquidity.   Discussions  and
 negotiations were held with Span Optics, COSI Computer Outsourcing, Anacomp, El
 Camino, Strategia and VariLease,

     none of which  materialized  into an offer  for the  Common  Shares  or the
     Company's assets.

           Since  December  1998,  the  Company  has  had  difficulty  obtaining
   financing to meet its short-term working capital  requirements and has had to
   rely on funding from affiliates. The Company was able to obtain a credit

    facility,  which includes a revolving  line of credit,  with Crestar Bank in
    1997 to fund its operations. The credit facility expired in October 1998 and
    continued under a forbearance agreement until May 1999, so that

  Crestar Bank could reevaluate the Company's financial operations. Crestar Bank
  decided not to extend the credit facility for another year.  However,  Crestar
  Bank extended the credit line while the Company attempted to obtain

    alternative financing.  The Company attempted without success to establish a
  new line of credit with several  lenders,  including  IBM Credit  Corporation,
  FINOVA Distribution, FINOVA Special Credit Division and Sandy Spring

National Bank ("Sandy Spring"). In October 1999, Crestar Bank reduced the credit
line from $2,000,000 to $1,750,000.  On March 6, 2000, Crestar Bank notified the
Company of its intention to terminate the revolving  credit line by reducing the
line from  $1,750,000  to  $1,500,000  on March 17, 2000,  and $100,000 per week
thereafter  until the credit line reaches zero. The Company has informed us that
it cannot  continue to operate under this financing  arrangement  and could face
bankruptcy if it is unable to secure  alternative  financing for its  operations
and the  repayment  of the  credit  facility.  The  credit  line is  secured  by
substantially  all of the  Company's  assets.  At  April  24,  2000,  there  was
$1,500,000 outstanding under the credit line.

In response to the  reduction of  available  funds under the Crestar Bank credit
facility,  during fiscal years 1999 and 2000, we advanced approximately $375,000
and  $595,000,  respectively,  to the Company to cover  operating  expenses.  We
provided  the funding to the  Company at an  interest  rate of prime plus 1% per
annum,  with  principal  repayable  on our  demand.  Mr.  Donald C.  Weymer owns
approximately  98% of our equity  securities.  Mr. Weymer is our founder,  Chief
Executive  Officer,  President  and a Director.  In  addition,  Mr.  Weymer owns
approximately 32% of the Common Shares.  Mr. Weymer is the Company's Chairman of
the Board of Directors, Chief Executive Officer and Secretary.

            In November 1999, we began discussions with the Company to assist it
 in working out the Crestar Bank credit facility.  On March 30, 2000, we entered
 into an amended and restated loan and security agreement with our
     lender,  Sandy Spring,  to increase our existing line of credit,  provided,
     among other things,  that we use a portion of the funds  available to repay
     the amounts due under the Company's  credit facility with Crestar Bank. The
     increased  line of  credit  is  secured  by our  assets  and  those  of our
     subsidiary, National Conversion Systems, Inc.("NCS"). It is also personally
     guaranteed  by Mr.  Weymer.  We  intend to repay  the  amounts  owed by the
     Company  under the Crestar  Bank credit  facilityupon  the  acceptance  for
     payment of all Common Shares validly tendered pursuant to the Offer.

              In addition to the Offer we are making herein,  we proposed to the
  Company two other acquisition  alternatives:  a "two-step" tender offer, which
  is a tender offer followed by a merger,  or a merger.  The Company  advised us
  that its Board of Directors unanimously agreed on March 24, 2000 that a tender
  offer  would be in the best  interests  of the  Company  and its  shareholders
  because (i) it would not be as costly and protracted as the

other two transactions  proposed by ISI, (ii) it would enable the Company to pay
off the Crestar Bank credit  facility,  thereby avoiding a sale of the Company's
assets by Crestar  Bank to cover the  Company's  indebtedness  under that credit
facility, and (iii) it would provide liquidity to those Company stockholders who
want it at a time when the Company is  experiencing  financial  difficulty.  The
Company also advised us that its Board of Directors  supports the Offer  because
the Company's accountants, Goldstein GolubKessler, LLP, recently issued a "going
concern opinion" in connection with their report on the Company's 1999 financial
statements.  Such an opinion was also issued with respect to the Company's  1998
financial statements.

We arrived at the tender  price of $1.00 per Common Share in cash by taking into
consideration  the  following  factors:  (i) that the current  book value of the
Company is  $1,248,485,  or $0.33 per Common  Share;  (ii) that we estimate  the
current liquidation value of the Company,  which is negative,  to be $(1.00) per
Common  Share;  (iii) that market  prices of the Common  Shares over the past 90
days  ranged  between  $0.72 and $1.00 per Common  Share;  and (iv) that  Common
Shares have only traded on 25 out of the past 60 trading  days,  and during such
period,the total number of Common Shares traded amounted toless than one-half of
1% of the total  outstanding  Common  Shares.  See  Section  5, page 15 for more
information.

II.           PURPOSE and PLANS

The purpose of the Offer is to enable us and our  affiliates to acquire  control
of, and the entire equity interest in, the Company.  Our current intention is to
retain the Common  Shares that we acquire in the Offer.  As  discussed  above in
"Background  of the  Offer,"  we have  decided to make the Offer at this time in
lieu of engaging in a "two-step" tender offer and merger transaction or a merger
transaction  because of the Company's  need to workout its credit  facility with
Crestar Bank quickly. The Offer is appropriate at this time because it will best
serve the interests of the Company and its  shareholders  and maximize the value
of the Company. We intend to operate the Company as a majority  owned-subsidiary
if we,  along with Mr.  Donald C. Weymer,  hold a majority of the Common  Shares
upon the acceptance for payment of all Common Shares validly  tendered  pursuant
to the Offer.  This should allow us to reduce certain of theCompany's  costs and
expenses and to capitalize on certain  synergies  between ISI and the Company.If
all of the Company's  stockholders do not tender all of their Common Shares,  we
intend to evaluate whether, under the circumstances at that time, it would be in
the best interests of ISI and the Company to acquire additional Common Shares by
means of a second tender offer, merger or other transaction.  Except as noted in
this Offer,  the Company and ISI have no present  plans that would result in any
extraordinary   corporate  transaction,   such  as  a  merger,   reorganization,
liquidation,  or sale or transfer of a material amount of assets,  involving the
Company or any  subsidiary of the Company or any other  material  changes in the
Company's  capitalization,dividend  policy,  corporate  structure,  business  or
composition of its management or Board of Directors.

     This Offer was not designed to be a "going private  transaction"  under the
     Securities  Exchange Act of 1934, as amended (the  "Exchange  Act") because
     each class of the equity  securities of the Company is already held by less
     than 300 holders of record. In addition, the Company has advised us that it
     does not intend to file a Form 15 to terminate its  registration  under the
     Exchange Act. Rather, the Company intends to remain a public company and to
     continue to file periodic  reports,  and to satisfy the other  requirements
     under the Exchange Act, so that the Common Shares will remain listed on the
     OTCBB.  Under the rules of the OTCBB,  the Company  must remain a reporting
     company  under the  Exchange  Act in order for the Common  Shares to remain
     listed on the OTCBB.

III.  MATERIAL UNITED STATES FEDERAL INCOME TAX EFFECTS

     Your  receipt of cash for the Common  Shares in the Offer will be a taxable
     transaction for United States federal income tax purposes and may also be a
     taxable  transaction under applicable state,  local,  foreign and other tax
     laws.  For  United  States  federal  income  tax  purposes,  if you sell or
     exchange your Common  Shares in the Offer,  you would  generally  recognize
     gain or loss equal to the  difference  between the amount of cash  received
     and your tax basis for the Common Shares that you sold or  exchanged.  That
     gain or loss will be capital  gain or loss  (assuming  you hold your Common
     Shares as a capital asset),  and any such capital gain or loss will be long
     term if,  as of the date of sale or  exchange,  you  have  held the  Common
     Shares  for more than one year or will be short  term if, as of such  date,
     you have held the Common Shares for one year or less.

     The   discussion   above  may  not  be   applicable  to  certain  types  of
     stockholders, including stockholders who acquired the Common Shares through
     the    exercise   of   employee    stock    options   or    otherwise    as
     compensation,individuals  who are not  citizens or  residents of the United
     States,  foreign  corporations,  or entities that are otherwise  subject to
     special tax treatment  under the Internal  Revenue Code of 1986, as amended
     (such as insurance

     THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED
     FOR GENERAL  INFORMATION  ONLY.  YOU ARE URGED TO CONSULT  YOUR TAX ADVISOR
     WITH  RESPECT  TO THE  SPECIFIC  TAX  CONSEQUENCES  TO  YOU  OF THE  OFFER,
     INCLUDING   UNITED  STATES  FEDERAL,   STATE  AND  LOCAL  AND  FOREIGN  TAX
     CONSEQUENCES.

                                    THE OFFER

1.             TERMS OF THE OFFER

             Upon  the  terms  and  subject  to  the  conditions  of  the  Offer
 (including,  if the Offer is extended or amended,  the terms and  conditions of
 any extension or  amendment),  we will  purchase all the Common Shares  validly
 tendered  and not  withdrawn in  accordance  with the  procedures  set forth in
 Section 4 on or prior to the Expiration

  Date. The term  "Expiration  Date" means 5:00 P.M.,  Eastern Time, on Tuesday,
   May 23,  2000,  unless we  extend  the  period of time for which the  initial
   offering period of the Offer is open, in which case the term "Expiration

 Date" will mean the time and date at which the initial  offering  period of the
Offer, as so extended, will expire.

          Upon the terms and  subject to the  conditions  of the Offer,  we will
  purchase,  as soon as permitted  under the terms of the Offer,  all the Common
  Shares validly tendered and not withdrawn prior to the Expiration Date.

     If, at the Expiration Date the conditions to the Offer described in Section
     10 have not been  satisfied  or earlier  waived,  then we may,  in our sole
     discretion,  extend the Expiration Date for an additional period or periods
     of time by giving oral or written notice of the extension to the Depositary
     and by publicly announcing the new Expiration Date. During any extension of
     the initial offering period (as opposed to the subsequent offering period),
     all the Common Shares  previously  tendered and not  withdrawn  will remain
     subject to the Offer and subject to your right to withdraw. See Section 4.

     Subject  to the  applicable  regulations  of the  Securities  and  Exchange
     Commission (the "SEC"),  we also reserve the right, in our sole discretion,
     at any time or from time to time, to (a)  terminate  the Offer  (whether or
     not any of the Common Shares have previously been purchased pursuant to the
     Offer) if any condition referred to in Section 10 has not been satisfied or
     earlier waived or upon the occurrence of any event specified in Section 10;
     and (b) waive any condition or otherwise amend the Offer in any respect, in
     each case, by giving oral or written notice of the  termination,  waiver or
     amendment to the Depositary and, other than, in the case of any waiver,  by
     making a public announcement thereof. We acknowledge that (a) Rule 14e-1(c)
     under the  Exchange  Act  requires us to pay the  consideration  offered or
     return the Common Shares  tendered  promptly  after the  termination of the
     Offer and (b) we may not delay the  purchase of, or payment for, any of the
     Common  Shares upon the  occurrence  of any event  specified  in Section 10
     without extending the period of time during which the Offer is open.

     The rights we reserve in the  preceding  paragraph  are in  addition to our
     rights  pursuant to Section 10. Any extension,  termination or amendment of
     the  Offer  will  be  followed  as  promptly  as  practicable  by a  public
     announcement.  An  announcement in the case of an extension will be made no
     later than 9:00 a.m.,  Eastern  Time,  on the next  business  day after the
     previously  scheduled Expiration Date. Without limiting the manner in which
     we may choose to make any public  announcement,  subject to applicable  law
     (including  those rules under the Exchange  Act that require that  material
     changes be promptly  disseminated to holders of the Common Shares), we will
     have no obligation to publish,  advertise or otherwise communicate any such
     public  announcement  other than by issuing a release to the Dow Jones News
     Service, Reuters Newswire, Bloomberg Business News and PR Newswire.

          If we make a material change in the terms of the Offer, or if we waive
          a  material  condition  to the  Offer,  we will  extend  the Offer and
          disseminate additional Offer materials to the extent required by Rules
          14d-4(d),  14d-6(c)  and 14e-1  under the  Exchange  Act.  The minimum
          period during which a tender offer must remain open following material
          changes in the terms of the  offer,  other than a change in price or a
          change in percentage of securities sought,  depends upon the facts and
          circumstances,  including the materiality of the changes. In the SEC's
          view, a tender offer should remain open for a minimum of five business
          days from the date the  material  change is first  published,  sent or
          given to stockholders,  and, if material changes are made with respect
          to  information  that  approaches  the  significance  of price and the
          percentage of securities sought, a minimum of ten business days may be
          required to allow for adequate  dissemination  and investor  response.
          With  respect to a change in price,  a minimum ten business day period
          from  the date of the  change  is  generally  required  to  allow  for
          adequate dissemination to stockholders.  Accordingly, if, prior to the
          Expiration Date, we decrease the number of Common Shares being sought,
          or increase  or decrease  the  consideration  offered  pursuant to the
          Offer,  and if the Offer is  scheduled  to expire at any time  earlier
          than the period  ending on the tenth  business  day from the date that
          notice of the increase or decrease is first  published,  sent or given
          to  holders of the Common  Shares,  we will  extend the Offer at least
          until the expiration of such period of ten business days. For purposes
          of  theOffer,  a  "business  day" means any day other than a Saturday,
          Sunday or a United  States  federal  holiday and  consists of the time
          period from 12:01 a.m. through 12:00 midnight, Eastern Time.

          THE OFFER IS CONDITIONED  UPON THE  SATISFACTION OF THE CONDITIONS SET
          FORTH IN SECTION 10.

          Consummation  of the Offer is subject to the  conditions  set forth in
          Section 10. We reserve the right, in accordance with applicable  rules
          and  regulations of the SEC, to waive any or all of those  conditions.
          If,by the  Expiration  Date, any or all of those  conditions  have not
          been  satisfied,  we may, in the exercise of our good faith  judgment,
          elect to (a) extend the Offer,  and, subject to applicable  withdrawal
          rights,  retain all of the tendered Common Shares until the expiration
          of the Offer,  as  extended,  subject  to the terms of the Offer;  (b)
          waive all of the  unsatisfied  conditions,  and,  subject to complying
          with  applicable  rules and regulations of the SEC, accept for payment
          all of the Common  Shares so tendered;  or (c) terminate the Offer and
          not accept for payment any of the Common  Shares and return all of the
          tendered Common Shares to the tendering Company  stockholders.  In the
          event that we waive any  condition  set forth in  Section  10, the SEC
          may, if the waiver is deemed to  constitute  a material  change to the
          information previously provided to the Company stockholders,require
          that the  Offer  remain  open for an additional  period of time or
          that we  disseminate  information concerning such waiver.

          The Company has  provided us with its  stockholder  lists and security
          position  listings  for the  purpose  of  disseminating  the  Offer to
          holders of the Common Shares. We will mail this offer to purchase, the
          related  letterof  transmittal and other relevant  materials to record
          holders of the Common  Shares,  and we will  furnish the  materials to
          brokers,  dealers,  commercial  banks,  trust  companies  and  similar
          persons  whose  names,  or the names of whose  nominees,appear  on the
          securityholder   lists  or,  if   applicable,   that  are   listed  as
          participants in a clearing agency's  security  position  listing,  for
          forwarding to beneficial owners of the Common Shares.

          SUBSEQUENT  OFFERING PERIOD.  We reserve the right, in accordance with
          the rules and regulations of the SEC, to provide a subsequent offering
          period of three business days to 20 business days after the expiration
          of the initial  offering  period and our purchase of the Common Shares
          tendered.   A  subsequent  offering  period  would  give  the  Company
          stockholders  who do not tender in the initial offering period another
          opportunity  to tender their Common  Shares and receive the same Offer
          price. If we elect to provide a subsequent  offering  period,  we will
          disseminate  additional  Offer  materials,  if  necessary.  During the
          subsequent  offering period,  Company  stockholders  will not have the
          right to withdraw the Common  Shares  previously  tendered or tendered
          during the subsequent offering period.

2.   ACCEPTANCE FOR PAYMENT AND PAYMENT FOR THE COMMON SHARES

          Upon the terms and subject to the conditions of the Offer  (including,
          if we extend or amend the Offer, the terms and conditions of the Offer
          as so  extended  or  amended),  we will  purchase,  by  accepting  for
          payment,  and will pay for, all of the Common Shares validly  tendered
          and not withdrawn (as permitted by Section 4) prior to the  Expiration
          Date promptly after the later of (a) the  Expiration  Date and (b) the
          satisfaction  or  waiver of the  conditions  to the Offer set forth in
          Section 10. In addition,  subject to  applicable  rules of the SEC, we
          reserve the right to delay  acceptance for payment of, or payment for,
          the Common Shares pending  receipt of any  governmental  approvals set
          forth in Section 11.For  information with respect to approvals that we
          are  required  to obtain  prior to the  completion  of the Offer,  see
          Section 11.

          In all  cases,  we will pay for the  Common  Shares  purchased  in the
          Offer,  including during the subsequent  offering  period,  only after
          timely receipt by the Depositary of (a) certificates  representing the
          Common  Shares  ("Company  Certificates")  or timely  confirmation  (a
          "Book-Entry  Confirmation")  of the book-entry  transfer of the Common
          Shares into the  Depositary's  account at The Depository Trust Company
          (the "Book-Entry  Transfer  Facility")  pursuant to the procedures set
          forth in Section 3; (b) the  appropriate  letter of transmittal  (or a
          facsimile),  properly  completed and duly executed,  with any required
          signature  guarantees  or an Agent's  Message  (as  defined  below) in
          connection  with a book-entry  transfer;  and (c) any other  documents
          that the letter of transmittal requires.

             The term  "Agent's  Message"  means a  message  transmitted  by the
   Book-Entry  Transfer Facility to, and received by, the Depositary and forming
   a part of a Book-Entry Confirmation, which states that the Book-Entry

 Transfer Facility has received an express  acknowledgment  from the participant
 in the Book-Entry  Transfer  Facility  tendering the Common Shares that are the
 subject of the Book-Entry Confirmation that the participant has received and
 agrees to be bound by the terms of the  letter  of  transmittal participant.

          For  purposes  of the Offer,  we will be deemed to have  accepted  for
          payment,  and purchased,  the Common Shares  validly  tendered and not
          withdrawn  as,  if and  when we give  oral or  written  notice  to the
          Depositary of our acceptance of the Common Shares for payment pursuant
          to  the  Offer.In  all  cases,  upon  the  terms  and  subject  to the
          conditions  of the  Offer,  payment  for the Common  Shares  purchased
          pursuant  to the  Offer,  including  during  any  subsequent  offering
          period,  will be made by deposit of the purchase  price for the Common
          Shares with the Depositary,  which will act as agent for the tendering
          Company  stockholders for the purpose of receiving payment from us and
          transmitting payment to the validly tendering Company stockholders.

          UNDER NO CIRCUMSTANCES  WILL WE PAY INTEREST ON THE PURCHASE PRICE FOR
          THE COMMON SHARES, EXCEPT AS MAY BE REQUIRED BY APPLICABLE LAW.

          If we do not purchase any of the tendered  Common  Shares  pursuant to
 the  Offer  for  any  reason,  or if you  submit  the  Company  Certificates
 representing more Common Shares than you wish to tender, we will return the
Company Certificates  representing the unpurchased or untendered Common Shares,
without  expense to you (or, in the case of the Common  Shares  delivered by
book-entry transfer into the Depositary's account at the Book-Entry

          Transfer  Facility  pursuant to the procedures set forth in Section 3,
          the Common Shares will be credited to an account maintained within the
          Book-Entry  Transfer Facility),  as promptly as practicable  following
          the expiration,termination or withdrawal of the Offer.

          IF, PRIOR TO THE  EXPIRATION  DATE,  WE INCREASE THE PRICE  OFFERED TO
          HOLDERS OF THE COMMON  SHARES IN THE OFFER,  WE WILL PAY THE INCREASED
          PRICE TO ALL  HOLDERS OF THE COMMON  SHARES  THAT WE  PURCHASE  IN THE
          OFFER,  WHETHER  OR NOT THE COMMON  SHARES  WERE  TENDERED  BEFORE THE
          INCREASE IN PRICE.

          We reserve the right to  transfer or assign,  in whole or from time to
          time in part, to one or more of our  subsidiaries  or  affiliates  the
          right to purchase all or any portion of the Common Shares  tendered in
          the  Offer,butany  such transfer or assignment  will not relieve us of
          our  obligations  under the Offer or prejudice  your rights to receive
          payment  for the Common  Shares  validly  tendered  and  accepted  for
          payment in the Offer.

3.    PROCEDURES FOR ACCEPTING THE OFFER AND TENDERING SHARES

               VALID TENDER OF THE COMMON SHARES.  Except as set forth below, in
               order for you to tender  the  Common  Shares  in the  Offer,  the
               Depositary must receive the letter of transmittal (or a facsimile
               thereof),  properly  completed  and  signed,  together  with  any
               required signature guarantees or an Agent's Message in connection
               with a  book-entry  delivery  of the Common  Shares and any other
               documents that the letter of transmittal  requires at its address
               set forth on the back cover of this offer to purchase on or prior
               to the  Expiration  Date,  and  either (a) you must  deliver  the
               Company  Certificates  representing the tendered Common Shares to
               the  Depositary  or you  must  cause  your  Common  Shares  to be
               tendered  pursuant to the procedure for  book-entry  transfer set
               forth  below  and  the   Depositary   must   receive   Book-Entry
               Confirmation,  in each case, on or prior to the Expiration  Date,
               or (b) you must comply with the  guaranteed  delivery  procedures
               set forth below.

               THE METHOD OF  DELIVERY  OF COMPANY  CERTIFICATES,  THE LETTER OF
               TRANSMITTAL  AND ALL OTHER  REQUIRED  DOCUMENTS IS AT YOUR OPTION
               AND SOLE RISK, AND DELIVERY WILL BE CONSIDERED MADE ONLY WHEN THE
               DEPOSITARY  ACTUALLY  RECEIVES  THE  COMPANY   CERTIFICATES.   IF
               DELIVERY IS BY MAIL,  WE  RECOMMEND  USING  REGISTERED  MAIL WITH
               RETURN RECEIPT  REQUESTED,  PROPERLY  INSURED.  IN ALL CASES, YOU
               SHOULD ALLOW SUFFICIENT TIME TO ENSURE TIMELY DELIVERY.

               BOOK-ENTRY  TRANSFER.  The  Depositary  will establish an account
               with  respect to the  Common  Shares at the  Book-Entry  Transfer
               Facility for purposes of the Offer within two business days after
               the  date  of the  Offer.  Any  financial  institution  that is a
               participant in the system of the Book-Entry Transfer Facility may
               make  book-entry  delivery  of the Common  Shares by causing  the
               Book-Entry  Transfer  Facility to transfer the Common Shares into
               the Depositary's  account at the Book-Entry  Transfer Facility in
               accordance with the Book-Entry  Transfer  Facility's  procedures.
               However,  although  the Common  Shares may be  delivered  through
               book-entry transfer into theDepositary's  account at a Book-Entry
               Transfer  Facility,  the  Depositary  must  receive the letter of
               transmittal  (or  facsimile  thereof),   properly  completed  and
               signed,  with any required  signature  guarantees,  or an Agent's
               Message in connection with a book-entry  transfer,  and any other
               required documents, at its address set forth on the back cover of
               this offer to purchase on or before the  Expiration  Date, or you
               must  comply with the  guaranteed  delivery  procedure  set forth
               below.

               DELIVERY OF  DOCUMENTS  TO THE  BOOK-ENTRY  TRANSFER  FACILITY IN
               ACCORDANCE  WITH ITS PROCEDURES  DOES NOT CONSTITUTE  DELIVERY TO
               THE DEPOSITARY.

               SIGNATURE  GUARANTEES.  A bank,  broker,  dealer,  credit  union,
               savings  association  or other  entity  that is a member  in good
               standing of the Securities  Transfer Agents Medallion Program (an
               "Eligible  Institution") must guarantee signatures on all letters
               of  transmittal,  unless the Common Shares  tendered are tendered
               (a) by a  registered  holder of the  Common  Shares  that has not
               completed either the box labeled "Special Payment

   Instructions"or  the  box  labeled  "Special  Delivery  Instructions"  on the
                letter of  transmittal  or (b) for the  account  of an  Eligible
                Institution. See Instruction 1 of the letter of transmittal.

               If the  Company  Certificates  are  registered  in the  name of a
               person other than the signer of the letter of transmittal,  or if
               payment is to be made to, or Company Certificates for unpurchased
               Common  Shares are to be issued or  returned  to, a person  other
               than  the   registered   holder,   then  the   tendered   Company
               Certificates must be endorsed or accompanied by appropriate stock
               powers,  signed  exactly  as the name or  names of  theregistered
               holder or holders  appear on the Company  Certificates,  with the
               signatures on the Company Certificates or stock powers guaranteed
               by  an  Eligible   Institution  as  provided  in  the  letter  of
               transmittal.   See   Instructions  1  and  5  of  the  letter  of
               transmittal.

           If  the  Company   Certificates  are  forwarded   separately  to  the
     Depositary,  a properly  completed and duly executed  letter of transmittal
     (or manually signed facsimile) must accompany each delivery of the Company
     Certificates.

               GUARANTEED DELIVERY.  If you want to tender your Common Shares in
               the  Offer  and your  Company  Certificates  are not  immediately
               available or time will not permit all required documents to reach
               the Depositary on or before the Expiration Date or the procedures
               for book-entry  transfer cannot be completed on time, your Common
               Shares may nevertheless be tendered if you comply with all of the
               following guaranteed delivery procedures:

          - your tender is made by or through an Eligible Institution;

          -   the Depositary receives,  as described below, a properly completed
              and signed Notice of  Guaranteed  Delivery,  substantially  in the
              form made available by us, on or before the Expiration Date; and

               -  the  Depositary  receives  the  Company   Certificates  (or  a
               Book-Entry Confirmation)  representing all of the tendered Common
               Shares,  in proper  form for  transfer  together  with a properly
               completed and duly executed  letter of  transmittal  (or manually
               signed facsimile), with any required signature guarantees (or, in
               the case of a book-entry  transfer,  an Agent's  Message) and any
               other  documents  required  by the letter of  transmittal  within
               three  trading  days after the date of execution of the Notice of
               Guaranteed Delivery.

               You may deliver the Notice of Guaranteed  Delivery by hand,  mail
               or  facsimile  transmission  to the  Depositary.  The  Notice  of
               Guaranteed  Delivery  must  include a  guarantee  by an  Eligible
               Institution  in the form set forth in the  Notice  of  Guaranteed
               Delivery  and a  representation  that you own the  Common  Shares
               being  tendered  within  the  meaning  of Rule  14e-4  under  the
               Exchange Act. Guaranteed delivery procedures are not available in
               the subsequent offering period.

               Notwithstanding any other provision of the Offer, we will pay for
               the Common Shares only after timely  receipt by the Depositary of
               the Company Certificates for, or, of Book-Entry Confirmation with
               respect  to, the Common  Shares,  a properly  completed  and duly
               executed letter of transmittal (or facsimile  thereof),  together
               with any  required  signature  guarantees  (or,  in the case of a
               book-entry transfer,  an Agent's Message) and any other documents
               required by the appropriate  letter of transmittal.  Accordingly,
               payment might not be made to all of the tendering stockholders at
               the same time and will depend upon when the  Depositary  receives
               the Company  Certificates  or  Book-Entry  Confirmation  that the
               Common Shares have been transferred into the Depositary's account
               at a Book-Entry Transfer Facility.

               BACKUP UNITED STATES  FEDERAL INCOME TAX  WITHHOLDING.  Under the
               backup  United  States  federal  income  tax   withholding   laws
               applicable  to certain  stockholders  (other than certain  exempt
               stockholders,  including,  among  others,  all  corporations  and
               certain foreign  individuals),  the Depositary may be required to
               withhold  31% of  the  amount  of  any  payments  made  to  those
               stockholders  pursuant  to the Offer.  To prevent  backup  United
               States  federal  income tax  withholding,  you must  provide  the
               Depositary with your correct taxpayer  identification  number and
               certify that you are not subject to backup United States  federal
               income tax  withholding  by completing  the  Substitute  Form W-9
               included in the letter of transmittal.  Non-United States holders
               must  submit a  completed  Form W-8 BEN to  qualify  as an exempt
               recipient.  These forms may be obtained from the Depositary.  See
               Instructions 11 and 12 of the letter of transmittal.

               APPOINTMENT AS PROXY. By executing the letter of transmittal, you
               irrevocably  appoint  our  designees,  and each of them,  as your
               agents,   attorneys-in-fact  and  proxies,  with  full  power  of
               substitution in each, in the

    manner set forth in the letter of  transmittal,  to the full  extent of your
   rights with  respect to the Common  Shares that you tender and that we accept
   for payment  and with  respect to any and all other  Common  Shares and other
   securities  or rights issued or issuable in respect of those Common Shares on
   or after the date of this

 Offer. All such powers of attorney and proxies will be  considered  irrevocable
    and coupled with an interest in the tendered Common Shares. This appointment
    will be  effective  when  we  accept  your  Common  Shares  for  payment  in
    accordance  with the terms of the Offer.  Upon such  acceptance for payment,
    all other powers of attorney and

 proxies  given  by you with  respect  to your  Common  Shares  and  such  other
   securities or rights prior to such payment will be revoked,  without  further
   action,  and no subsequent powers of attorney and proxies may be given by you
   (and,  if given,  will not be deemed  effective).  Our designees  will,  with
   respect to the Common Shares and such

  other  securities  and  rights  for which the  appointment  is  effective,  be
    empowered to exercise all of your voting and other rights as they,  in their
    sole discretion, may deem proper at any annual or special meeting of the

  Company  stockholders,  or any  adjournment  or  postponement  thereof,  or by
   consent  in lieu of any such  meeting or  otherwise.  In order for the Common
   Shares to be deemed  validly  tendered,  immediately  upon the acceptance for
   payment of such Common  Shares,  we or our designee  must be able to exercise
   full voting rights with respect to

       such Common Shares and other securities,  including voting at any meeting
of the Company stockholders.

               DETERMINATION  OF  VALIDITY.  All  questions  as to the  form  of
               documents  and  the  validity,  eligibility  (including  time  of
               receipt) and  acceptance  for payment of any tender of the Common
               Shares will be  determined by us, in our sole  discretion,  which
               determination  will be  final  and  binding  on all  parties.  We
               reserve  the  absolute   right  to  reject  any  or  all  tenders
               determined by us not to be in proper form or the acceptance of or
               payment  for  which  may,  in  the  opinion  of our  counsel,  be
               unlawful.  We also reserve the absolute right to waive any of the
               conditions  of the  Offer or any  defect or  irregularity  in any
               tender  of  the   Common   Shares  of  any   particular   Company
               stockholder, whether or not similar defects or irregularities are
               waived in the case of other Company stockholders.

               No  tender  of the  Common  Shares  will be  deemed  to have been
     validly  made until all  defects  and  irregularities  with  respect to the
     tender have been cured or waived by us. None of ISI, the Company, the

               Depositary,  the  Information  Agent or any of  their  respective
               affiliates or assigns,  or any other individual or entity will be
               under  any  duty to  give  any  notification  of any  defects  or
               irregularities  in tenders or incur  anyliability  for failure to
               give any such notification.

           Our acceptance for payment of Common Shares tendered  pursuant to any
 of the procedures  described above will constitute a binding  agreement between
 us and you upon the terms and subject to the conditions of the Offer.

4.          WITHDRAWAL RIGHTS

               Except as  described  in this  Section  4,  tenders of the Common
               Shares made in the Offer are irrevocable. You may withdraw Common
               Shares that you have previously tendered in the Offer at any time
               on  or  before  the  Expiration  Date,  and,  unless  theretofore
               accepted for payment as provided  herein,  you may also  withdraw
               the  Common  Shares at any time after  June 25,  2000;  provided,
               however,  you may not  withdraw  the  Common  Shares  during  any
               subsequent offering period.

          If, for any reason, acceptance for payment of any of the Common Shares
     tendered in the Offer is delayed, or we are unable to accept for payment or
     pay for the Common Shares tendered in the Offer, then, without

               prejudice  to  our  rights  set  forth  in  this  document,   the
               Depositary may,  nevertheless,  on our behalf,  retain the Common
               Shares  that you have  tendered,  and you may not  withdraw  your
               Common Shares,  except to the extent that you are entitled to and
               duly exercise  withdrawal  rights as described in this Section 4.
               Any such delay will be by an extension of the Offer to the extent
               required by law.

                In order for your  withdrawal to be  effective,  you must timely
  deliver a written  or  facsimile  transmission  notice  of  withdrawal  to the
  Depositary at the address set forth on the back cover of this offer to

   purchase. Any such notice of withdrawal must specify your name, the number of
  Common Shares that you want to withdraw, and (if the Company Certificates have
  been tendered) the name of the registered holder of the Common

   Shares as shown on the Company  Certificate  if different  from your name. If
     the Company Certificates have been delivered or otherwise identified to the
     Depositary, then, prior to the physical release of such Company

   Certificates,  you must  submit the serial  numbers  shown on the  particular
      Company  Certificates  evidencing the Common Shares to be withdrawn and an
      Eligible Institution must guarantee the signature on the notice of

    withdrawal,  except in the case of Common Shares tendered for the account of
  an Eligible  Institution.  If the Common Shares have been tendered pursuant to
  the procedures for book-entry transfer set forth in Section 3, the

               notice of  withdrawal  must  specify  the name and  number of the
               account at the  appropriate  Book-Entry  Transfer  Facility to be
               credited with the withdrawn Common Shares, in which case a notice
               of withdrawal will be effective if delivered to the Depositary by
               any method of delivery  described  in the first  sentence of this
               paragraph. You may not rescind a withdrawal of the Common Shares.
               Any  Common  Shares  that you  withdraw  will be  considered  not
               validly  tendered for  purposes of the Offer,  but you may tender
               your Common Shares again at any time before the  Expiration  Date
               by following any of the procedures described in Section 3.

           All questions as to the form and validity (including time of receipt)
     of notices of withdrawal will be determined by us, in our sole  discretion,
     which determination will be final and binding. None of ISI, the

               Company,  the Depositary,  the Information  Agent or any of their
               respective  affiliates  or assigns,  or any other  individual  or
               entity  will be under  any duty to give any  notification  of any
               defects or irregularities in anynotice of withdrawal or incur any
               liability for failure to give any such notification.

5.            PRICE RANGE OF THE COMMON SHARES; DIVIDENDS

  share. The following table sets forth, for the periods indicated, the range of
  high and low bid prices for the Common Shares on the OTCBB.

            The               Company  has  informed  us that,  as of April  24,
                              2000, the Common Shares were held by 54 holders of
                              record.  The  Company  has never  declared  a cash
                              dividend.
STOCKHOLDERS ARE URGED TO OBTAIN CURRENT MARKET QUOTATIONS FOR THE COMMON SHARES

               6.  POSSIBLE  EFFECTS  OF THE OFFER ON THE  MARKET FOR THE COMMON
               SHARES; STOCK QUOTATION

           Our  purchase of the Common  Shares  pursuant to the Offer could have
 the following effects.  The purchase of the Common Shares pursuant to the Offer
 will reduce the number of Common Shares that might otherwise trade on

  the OTCBB and could  adversely  affect the  liquidity  and market value of the
  remaining  Common Shares held by the public,  as well as the  availability  of
  quotations for the value of the Common Shares.  We cannot predict  whether the
  reduction in the number of Common  Shares would have an adverse or  beneficial
  effect  on the  market  price for or  marketability  of the  Common  Shares or
  whether it would cause future market prices to be greater or less than

 the tender price. The  availability of market  quotations would depend upon the
  number of holders of Common Shares  remaining at such time and the interest in
  maintaining a market in the Common Shares on the part of securities firms.

               information technology outsourcing, enterprise systems management
               and   not-for-profit   solutions  to  commercial  and  non-profit
               organizations.

               Donald C. Weymer owns  approximately 98% of our equity securities
               and is our founder,  Chief  Executive  Officer,  President  and a

               Board of Directors, Chief Executive Officer and Secretary.

             We do not own any Common Shares directly.  We have an option
              to purchase  all  outstanding  shares of common  stock of
              Cintronix, a wholly owned subsidiary of the Company.

            The  name,   business   address,   citizenship,   present  principal

      years (a) been convicted in a criminal proceeding (excluding traffic

               violations  or similar  misdemeanors)  or (b) been a party to any
               judicial or  administrative  proceeding  (except for matters that
               were dismissed without sanction or settlement) that resulted in a
               judgment,  decree or final order enjoining the person from future
               violations  of, or  prohibiting  activities  subject  to,  United
               States federal or state  securities laws or finding any violation
               of such laws.

          Except as set forth elsewhere in the Offer or Schedule I to this offer
  to purchase:  (a) neither we nor, to our knowledge,  any of the persons listed

         option  arrangements,  puts or calls,  guaranties of loans,  guaranties
         against loss or the giving or withholding of proxies, consents or

  authorizations);  (d) in the past two years,  there have been no  transactions
    that would  require  reporting  under the rules and  regulations  of the SEC
    between us or any of our subsidiaries or, to our knowledge, any of the

   persons listed in Schedule I, on the one hand,  and the Company or any of its
    executive officers,  directors or affiliates,  on the other hand; and (e) in
    the past two years, there have been no contacts, negotiations or

               transactions  between  us or any of our  subsidiaries  or, to our
               knowledge,  any of the  persons  listed in Schedule I, on the one
               hand, and the Company or any of its  subsidiaries  or affiliates,
               on  the  other  hand,  concerning  a  merger,   consolidation  or
               acquisition,  a Offer  or other  acquisition  of  securities,  an
               election of directors  or a sale or other  transfer of a material
               amount of assets.

9.             SOURCE AND AMOUNT OF FUNDS

          We estimate that the total amount of funds required to purchase all of
 the outstanding Common Shares not already held by Mr. Donald C. Weymer pursuant
 to the Offer (exclusive of fees and expenses) will be approximately

 $2,520,888.  We intend to obtain the funds  necessary  to purchase  the Common
 Shares  pursuant to the Offer and to pay related  fees and  expenses  from an
 existing line of credit we have with Sandy Spring and from our working capital.

              We intend to obtain the funds  necessary  to  purchase  the Common
   Shares  primarily from an existing  $4,000,000  line of credit under a credit
   facility that ISI has with Sandy Spring. On March 30, 2000, ISI and

 Sandy Spring  executed an amended and restated loan and security  agreement and
  related  promissory  note to increase  the line of credit from  $2,000,000  to
  $4,000,000, copies of which are filed as Exhibit (b)(1) to a Schedule TO,
 which we have filed with the SEC,  and are  summarized  below (the
"Security Agreement").

               The Security Agreement,  which expires on June 30, 2001, provides
               that the funds will be available at an interest  rate of 1% above
               prime per annum.  Interest  on the line of credit  will be repaid
               monthly.  The line of credit is the obligation of ISI and will be
               jointly and severally guaranteed by Mr. Weymer. In addition,  Mr.
               Weymer  has agreed by  separate  agreement  with Sandy  Spring to
               subordinate   any  claims  he  may  have  against  ISI  regarding
               indebtedness to claims arising under the Security  Agreement with
               Sandy Spring.

               The line of credit is secured by a first lien  security  interest
               in: all of ISI's and NCS'  receivables,  inventory and equipment,
               and all  property  and funds of ISI now owned or later  acquired;
               (b) all of ISI's andNCS' assets for which Sandy Spring  currently
               has or later  acquires a lien;  (c) all  proceeds and products of
               the foregoing items; and (d) all intellectual property rights and
               general intangibles.

           The Security  Agreement also contains  terms and conditions  that are
 customary  for  credit  facilities  of this  type,  including  terms  that will
 obligate ISI to: (a) limit its outstanding principal balance under the line

    of credit to 75% of  eligible  accounts  receivable;  (b)  maintain  certain
  ratios, including current assets to liabilities,  debt to worth, and cash flow
  to debt  service;  and (c) obtain Sandy  Spring's  prior  written  consent for
  extraordinary transactions, such as the purchase of stock of another entity, a
  merger or consolidation,  or the acquisition of subsidiaries.  Pursuant to the
  written consent provisions of the Security Agreement, ISI has

 obtained a consent  letter  from  Sandy  Spring  authorizing  the Offer and all
  actions  relating  to, or resulting  from,  the Offer.  The consent  letter is
  attached as Exhibit (b)(2) to a Schedule TO, which we have filed with the SEC.

  Any  additional  funds  that  may be necessary   to   purchase   the
 Common  Shares will be obtained from our working capital.

10.    CONDITIONS OF THE OFFER

          Notwithstanding  any other provision of the Offer, ISI is not required
 to accept for payment or (subject to any  applicable  rules and  regulations of
 the SEC) pay for, and may delay the acceptance for payment of, any of

  the tendered Common Shares and may terminate or amend the Offer, unless at any

 of the following conditions exists or has occurred and remains in effect:

               (1) There is pending any action by any  governmental  entity,  or

               its or the  Company's or any of its  subsidiaries'  businesses or
               assets,  or to compel ISI or its  subsidiaries  and affiliates to
               dispose of or hold separate any material  portion of the business
               or  assets   of  the   Company   or  ISI  and  their   respective
               subsidiaries, in each case, taken as a whole,

               - seeking to or that does make the  acceptance for payment of, or
               the  payment  for,  some or all of the Common  Shares  illegal or
               otherwise  prohibiting,  restricting  or  significantly  delaying
               consummation  of the Offer, or seeking to obtain from the Company
               or ISI any damages that are material in ISI's view in relation to

               effectively to control in any material  respect in ISI's view the

           -     seeking to or that does  impose  circumstances  under which the
                 purchase  or  payment  for  some  or all of the  Common  Shares
                 pursuant  to the Offer could  reasonably  be expected to have a
                 material adverse effect on ISI, or

               - that otherwise would  reasonably be expected to have a material
               adverse effect on the Company or ISI; or

               (2) There has  occurred  any  change  that  could  reasonably  be
               expected to constitute a material  adverse  effect on the Company
               or ISI; or

               for a period in

                excess  of  24  hours  (excluding   suspensions  or  limitations
                  resulting  solely from physical  damage or  interference  with
                  such  exchanges  not  related to market  conditions),  (B) the
                  declaration of a

                 directly or indirectly,  involving the United  States,  (D) any
                  mandatory   limitation  by  any  United  States   governmental
                  authority or agency that would  reasonably be expected to have
                  a material

                adverse  effect  on the  extension  of  credit by banks or other
                 financial  institutions,  or  (E)  in  the  case  of any of the
                 foregoing,  existing  at the  time of the  commencement  of the
                 Offer, a material acceleration or worsening thereof; or

(4)  The Offer has been terminated in accordance with its terms; or

(5)             (A) The Company's  Board of Directors has withdrawn,  changed or
                modified    (including    by   amendment   of   the    Company's
                Solicitation/Recommendation  Statement  on Schedule  14D-9) in a
                manner adverse to ISI its

               approval or  recommendation  of the Offer or has  recommended  an
               acquisition proposal, or has adopted any resolution to effect any
               of the  foregoing,  (B) the  Company's  Board  of  Directors  has
               recommended  any  proposal  other than the Offer in respect of an
               acquisition proposal, (C) the Company's Board of

                 Directors  has  continued  discussions  with  any  third  party
                  concerning an acquisition  proposal for more than ten business
                  days after the date of receipt of such  acquisition  proposal,
                  or (D) an

                acquisition   proposal  that  is  publicly  disclosed  and  that
               contains a proposal as to price  (without  regard to whether such
               proposal  specifies  a  specific  price or a range  of  potential
               prices) has been

                commenced,  publicly proposed or communicated to the Company and
                   the  Company's  Board  of  Directors  has not  rejected  such
                   proposal  within ten business days of the earlier to occur of
                   (i) the

               Company's receipt of such acquisition  proposal and (ii) the date
               such acquisition proposal first becomes publicly disclosed; or

(6)            Not all consents,  permits and approvals of governmental entities
               and other persons have been  obtained  without  material  adverse
               conditions  attached and material expenses imposed on the Company
               or any of its subsidiaries; or

               (7) ISI shall become aware that any material contractual right of
               the  Company  or any of its  subsidiaries  shall be  impaired  or
               otherwise  adversely  affected  as a result  of the  transactions
               contemplated by the Offer, or any covenant,  term or condition in
               any of the Company's or any of its  subsidiaries'  instruments or
               agreements that are or may be materially  adverse to the value of
               the Common  Shares in the hands of ISI or any other  affiliate of
               ISI (including, without limitation, any event of default that may
               ensue as a result of the  consummation of the Offer, or any other
               business  combination  or  the  acquisition  of  control  of  the
               Company); or

(8)            ISI shall have  reached an agreement  or  understanding  with the
               Company  providing for  termination  of the Offer,  or ISI or any
               other  affiliate  of ISI shall  have  entered  into a  definitive
               agreement or shall have  announced an agreement in principle with
               the Company providing for a merger or other business  combination
               with the  Company  or the  purchase  of stock  or  assets  of the
               Company; which, in the sole

               judgment  of  ISI  in  any  such  case,  and  regardless  of  the
               circumstances  (including  any action or  inaction  by ISI or any
               other affiliate of ISI) giving rise to any such condition,  makes
               it  inadvisable  to  proceed  with the  Offer  and/or  with  such
               acceptance of payment or payment.

               The foregoing conditions are for the sole benefit of ISI. ISI may
               assert the  failure of any of the  conditions  regardless  of the
               circumstances  (other than any circumstance arising solely by any
               action or inaction by ISI) giving rise to any such  failure.  The
               conditions  may be waived by ISI in whole or in part at any time.
               The failure by ISI at any time to exercise  any of the  foregoing
               rights  shall not be deemed a waiver of any such right,  and each
               such right shall be deemed an ongoing  right that may be asserted
               at any time.

          A     public  announcement  may be made of a  material  change  in, or
                waiver  of,   such   conditions.   The  Offer  may,  in  certain
                circumstances, be extended in connection with any such change or
                waiver.

               ISI acknowledges that the SEC believes that (a) if ISI is delayed
               in accepting the Common  Shares,  it must either extend the Offer
               or terminate the Offer and promptly return the Common Shares, and
               (b) thecircumstances in which a delay in payment is permitted are
               limited and do not include  unsatisfied  conditions of the Offer,
               except with respect to most required regulatory approvals.

11.              LEGAL AND REGULATORY MATTERS

               GENERAL. Except as set forth in the Offer, based on our review of
               publicly  available filings by the Company with the SEC and other
               information  regarding  the  Company,  we are  not  aware  of any
               licenses or regulatory  permits that appear to be material to the
               business of the Company and its  subsidiaries,  taken as a whole,
               that might be adversely affected by our acquisition of the Common
               Shares  in the  Offer.  In  addition,  we are  not  aware  of any
               filings,  approvals or other actions by or with any  governmental
               entity or  administrative  or  regulatory  agency  that  would be
               required for our  acquisition  or ownership of the Common Shares.
               Should any such approval or

  other action be required, we expect to seek such approval or action, except as
 described under "State Takeover Laws." Should any such approval or other action
 be  required,  we cannot be  certain  that we would be able to obtain  any such
 approval or action without substantial conditions, or that adverse consequences
 might not result to the

               Company's or its subsidiaries'  businesses, or that certain parts
               of the Company's,  ISI's or any of their respective subsidiaries'
               businesses  might not have to be disposed of or held  separate in
               order to obtain such  approval or action.  In that event,  we may
               not be required to purchase any Common  Shares in the Offer.  See
               Section 10 for a description of the conditions to the Offer.

            STATE TAKEOVER LAWS. A number of states (including  Delaware,  where
  the Company is  incorporated)  have adopted takeover laws and regulations that
  purport,  to  varying  degrees,  to  be  applicable  to  attempts  to  acquire
  securities of corporations  that are incorporated in those states or that have
  substantial assets, stockholders,

               principal  executive  offices or principal  places of business in
               those states.  To the extent that these state  takeover  statutes
               purport  to  apply to the  Offer,  we  believe  that  those  laws
               conflict   with   United   States   federal   law   and   are  an
               unconstitutional  burden  on  interstate  commerce.  We have  not
               attempted  to  comply  with  any  state   takeover   statutes  in
               connection  with the Offer. We reserve the right to challenge the
               validity or applicability  of any state law allegedly  applicable
               to the Offer,  and  nothing  in the Offer nor any action  that we
               take in connection with the Offer is intended as a waiver of that
               right. In the event that it is asserted that one or

               more  takeover  statutes  apply  to  the  Offer,  and  it is  not
               determined by an appropriate  court that the statutes in question
               do  not  apply  or are  invalid  as  applied  to  the  Offer,  as
               applicable, we may be required to file certain documents with, or
               receive  approvals from, the relevant state  authorities,  and we
               might be unable to accept  for  payment  or  purchase  the Common
               Shares  tendered  in the Offer or be  delayed  in  continuing  or
               consummating  the Offer. In that case, we may not be obligated to
               accept  for  purchase,  or pay  for,  any of  the  Common  Shares
               tendered. See Section 10.

               ANTITRUST. We do not believe that the Hart-Scott-Rodino Antitrust
               Improvements  Act of  1976,  as  amended,  is  applicable  to the
               acquisition of Common Shares contemplated by our offer.

           MARGIN  REQUIREMENTS.  The Common Shares are not "margin  securities"
  under the  regulations of the Board of Governors of the Federal Reserve System
  and, accordingly, such regulations are not applicable to our offer.

12.       FEES AND EXPENSES

               We have retained D.F.  King & Co., Inc. as  Information  Agent in
               connection  with the Offer.  The  Information  Agent may  contact
               holders of the Common Shares by mail, telephone, telex, telegraph
               and personal interview and may request brokers, dealers and other
               nominee stockholders to forward material relating to the

    Offer to beneficial owners of the Common Shares. We will pay the Information
 Agent  reasonable and customary  compensation for these services in addition to
 reimbursing the Information Agent for its reasonable out-of-pocket

      expenses.  We have  agreed to  indemnify  the  Information  Agent  against
     certain  liabilities and expenses in connection  with the Offer,  including
     certain liabilities under the United States federal securities laws.

          In  addition,  we have  retained  Continental  Stock  Transfer & Trust
     Company  as the  Depositary.  We will  pay the  Depositary  reasonable  and
     customary compensation for its services in connection with the Offer, will

   reimburse the Depositary for its reasonable  out-of-pocket  expenses and will
        indemnify  the  Depositary  against  certain  liabilities  and expenses,
        including certain liabilities under the federal securities laws.

               Except  as  set  forth  above,  we  will  not  pay  any  fees  or
               commissions to any broker,  dealer or other person for soliciting
               tenders  of the Common  Shares  pursuant  to the  Offer.  We will
               reimburse brokers, dealers,  commercial banks and trust companies
               and other  nominees,  upon request,  for  customary  clerical and
               mailing  expenses   incurred  by  them  in  forwarding   offering
               materials to their customers.

              ISI has paid or will be responsible  for paying all other expenses
in connection with the Offer.

13.               MISCELLANEOUS

                 We are not aware of any jurisdiction in which the making of the
   Offer is prohibited by any  administrative or judicial action pursuant to any
   valid  state  statute.  If  we  become  aware  of  any  valid  state  statute
   prohibiting  the making of the Offer or the  acceptance of the Common Shares,
   we will make a good faith

               effort to comply with that state statute.  If, after a good faith
               effort, we cannot comply with the state statute, we will not make
               the Offer to,  nor will we accept  tenders  from or on behalf of,
               the holders of the Common Shares in that state.

              We have filed with the SEC a Schedule TO,  together with exhibits,
    furnishing certain additional information with respect to the Offer, and may
    file amendments to the Schedule TO. The Schedule TO and any

               exhibits or amendments may be examined and copies may be obtained
               from the SEC in the same  manner as  described  in Section 7 with
               respect to information concerning the Company, except that copies
               will not be available at the regional offices of the SEC.

               WE HAVE NOT AUTHORIZED  ANY PERSON TO GIVE ANY  INFORMATION OR TO
               MAKE ANY  REPRESENTATION  ON OUR BEHALF THAT IS NOT  CONTAINED IN
               THIS OFFER TO  PURCHASE OR IN THE LETTER OF  TRANSMITTAL  AND, IF
               GIVEN OR MADE,  YOU  SHOULD NOT RELY ON ANY SUCH  INFORMATION  OR
               REPRESENTATION.

               PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     The  undersigned  hereby tenders to Interactive  Systems,  Inc., a Virginia
corporation (the "Purchaser"),  the above-described  shares of Common Stock, par
value $0.001 per share (the "Common Shares"), of CSI Computer Specialists, Inc.,
a Delaware  corporation  (the "Company"),  pursuant to the Purchaser's  offer to
purchase all  outstanding  Common Shares at $1.00 per Common  Share,  net to the
seller in cash (less any required withholding taxes),  without interest thereon,
upon the terms and subject to the  conditions set forth in the Offer to Purchase
dated  April 26,  2000 (the  "Offer to  Purchase"),  receipt  of which is hereby
acknowledged,  and in this letter of transmittal  (the "Letter of  Transmittal,"
which together with the Offer to Purchase,  as amended or supplemented from time
to time, collectively constitute the "Offer").

     Subject to, and effective upon, acceptance for payment of the Common Shares
tendered  herewith,  in accordance with the terms of the Offer,  the undersigned
hereby sells,  assigns and transfers to, or upon the order of, the Purchaser all
right,  title  and  interest  in and to all the  Common  Shares  that are  being
tendered hereby and all dividends, distributions (including, without limitation,
distributions  of  additional  Common  Shares)  and  rights  declared,  paid  or
distributed  in  respect  of such  Common  Shares  on or after  April  26,  2000
(collectively,  "Distributions")  and  irrevocably  appoints  Continental  Stock
Transfer  & Trust  Company  (the  "Depositary")  the true and  lawful  agent and
attorney-in-fact  of the undersigned  with respect to such Common Shares and all
Distributions,  with full power of  substitution  (such power of attorney  being
deemed to be an  irrevocable  power  coupled with an  interest),  to (i) deliver
certificates   representing   Common  Shares  ("Share   Certificates")  and  all
Distributions, or transfer ownership of such Common Shares and all Distributions
on the account books maintained by the Book-Entry  Transfer Facility,  together,
in either case, with all accompanying evidences of transfer and authenticity, to
or upon the order of the  Purchaser;  (ii)  present  such Common  Shares and all
Distributions  for transfer on the books of the Company;  and (iii)  receive all
benefits  and  otherwise  exercise  all rights of  beneficial  ownership of such
Common Shares and all  Distributions,  all in  accordance  with the terms of the
Offer.

     The undersigned hereby  irrevocably  appoints designees of the Purchaser as
agent,  attorney-in-fact  and proxy of the undersigned,  each with full power of
substitution,  to vote in such manner as such  attorney  and proxy or his or her
substitute  shall, in his or her sole discretion,  deem proper and otherwise act
(by written consent or otherwise) with respect to all the Common Shares tendered
herewith and which have been accepted for payment by the Purchaser  prior to the
time of such vote or other  action  and all Common  Shares and other  securities
issued in  Distributions  in respect of such Common Shares which the undersigned
is  entitled  to vote at any meeting of  stockholders  of the  Company  (whether
annual or special  and  whether or not an  adjourned  or  postponed  meeting) or
consent  in lieu of any such  meeting  or  otherwise.  This  proxy  and power of
attorney is coupled with an interest in the Common Shares tendered herewith,  is
irrevocable  and is granted in  consideration  of, and is  effective  upon,  the
acceptance for payment of such Common Shares by the Purchaser in accordance with
the terms of the Offer.  Such  acceptance  for  payment  shall  revoke all other
proxies  and  powers of  attorney  granted by the  undersigned  at any time with
respect to such Common Shares (and all Common Shares and other securities issued
in Distributions  in respect of such Common Shares),  and no subsequent proxy or
power of attorney  shall be given or written  consent  executed (and if given or
executed,  shall not be effective) by the undersigned with respect thereto.  The
undersigned  understands  that,  in order  for the  Common  Shares  to be deemed
validly  tendered,  immediately  upon the Purchaser's  acceptance of such Common
Shares for payment the  Purchaser or its designee  must be able to exercise full
voting,  consent and other rights with  respect to such Common  Shares and other
securities,  including,  without  limitation,  voting  at  any  meeting  of  the
Company's stockholders.

     The  undersigned  hereby  represents and warrants that the  undersigned has
full power and authority to tender,  sell, assign and transfer the Common Shares
tendered  herewith and all  Distributions,  and that when such Common Shares are
accepted  for  payment  by the  Purchaser,  the  Purchaser  will  acquire  good,
marketable and  unencumbered  title thereto and to all  Distributions,  free and
clear of all liens,  restrictions,  charges and  encumbrances,  and that none of
such Common Shares or  Distributions  will be subject to any adverse claim.  The
undersigned,  upon request,  shall execute and deliver all additional  documents
deemed by the  Depositary  or the  Purchaser  to be  necessary  or  desirable to
complete  the sale,  assignment  and  transfer  of the  Common  Shares  tendered
herewith and all  Distributions.  In addition,  the undersigned  shall remit and
transfer  promptly  to the  Depositary  for the  account  of the  Purchaser  all
Distributions  in respect of the Common Shares  tendered hereby and accepted for
payment,  accompanied by appropriate documentation of transfer, and pending such
remittance and transfer or appropriate assurance thereof, the Purchaser shall be
entitled to all rights and privileges as owner of each such Distribution and may
withhold the entire  purchase  price of the Common  Shares  tendered  hereby and
accepted for payment, or deduct from such purchase price, the amount or value of
such Distribution as determined by the Purchaser in its sole discretion.

     No authority  herein  conferred or agreed to be conferred shall be affected
by,  and all such  authority  shall  survive,  the  death or  incapacity  of the
undersigned.  All obligations of the undersigned hereunder shall be binding upon
the heirs, personal representatives,  successors and assigns of the undersigned.
Except as  stated in the Offer to  Purchase,  this  tender is  irrevocable.  See
Section 4 in the Offer to Purchase.

     The undersigned  understands  that tenders of Common Shares pursuant to any
one of the  procedures  described in Section 3,  "Procedures  for  Accepting the
Offer and  Tendering  Shares," of the Offer to Purchase and in the  instructions
hereto will constitute the undersigned's  acceptance of the terms and conditions
of the Offer. The Purchaser's  acceptance of such Common Shares for payment will
constitute a binding  agreement  between the  undersigned and the Purchaser upon
the terms and  subject to the  conditions  of the Offer.  Without  limiting  the
foregoing,  if the price to be paid in the Offer is amended in  accordance  with
the Offer,  the price to be paid to the  undersigned  will be the amended  price
notwithstanding  the fact that a  different  price is  stated in this  Letter of
Transmittal.  The undersigned  recognizes that under certain  circumstances  set
forth in the Offer to Purchase,  the Purchaser may not be required to accept for
payment any of the Common Shares tendered hereby.

     Unless  otherwise  indicated  herein in the box entitled  "Special  Payment
Instructions,"  please  issue  the check for the  purchase  price of all  Common
Shares  purchased,  and  return  all Share  Certificates  not  purchased  or not
tendered in the name(s) of the registered  holder(s)  appearing above in the box
entitled  "Description of Common Shares Tendered."  Similarly,  unless otherwise
indicated in the box entitled "Special Delivery  Instructions,"  please mail the
check  for the  purchase  price of all  Common  Shares  purchased  and all Share
Certificates  not tendered or not  purchased  (and  accompanying  documents,  as
appropriate) to the address(es) of the registered  holder(s)  appearing above in
the box entitled  "Description of Common Shares Tendered." In the event that the
boxes   entitled   "Special   Payment   Instructions"   and  "Special   Delivery
Instructions" are both completed,  please issue the check for the purchase price
of all Common Shares  purchased and return all Share  Certificates not purchased
or not  tendered in the  name(s) of, and mail such check and Share  Certificates
to, the person(s) so indicated.  Unless  otherwise  indicated  herein in the box
entitled  "Special  Payment  Instructions,"  please  credit  any  Common  Shares
tendered  hereby  and  delivered  by  book-entry  transfer,  but  which  are not
purchased,  by crediting the account at the Book-Entry  Transfer  Facility.  The
undersigned  recognizes  that the Purchaser has no  obligation,  pursuant to the
Special Payment Instructions, to transfer any Common Shares from the name of the
registered  holder(s)  thereof if the  Purchaser  does not  purchase  any of the
Common Shares tendered herewith.

     The  undersigned  understands  that the  Purchaser  reserves  the  right to
transfer or assign,  in whole at any time,  or in part from time to time, to one
or more of its  affiliates,  the right to  purchase  all or any  portion  of the
Common  Shares  tendered  pursuant  to the  Offer,  but  any  such  transfer  or
assignment will not relieve the Purchaser of its obligations under the Offer and
will in no way prejudice the rights of tendering stockholders to receive payment
for Common  Shares  validly  tendered and  accepted for payment  pursuant to the
Offer.

     CHECK HERE IF ANY OF THE SHARE CERTIFICATES REPRESENTING COMMON SHARES THAT
     YOU OWN HAVE BEEN LOST OR DESTROYED AND SEE INSTRUCTION 9.

Transmittal must be guaranteed by an Eligible Institution. See Instruction 5.

2.  Delivery of Letter of  Transmittal  and Share  Certificates.  This Letter of
Transmittal  is to be used  either  if Share  Certificates  are to be  forwarded
herewith or,  unless an Agent's  Message (as defined  below) is used,  if Common
Shares are to be delivered by book-entry  transfer pursuant to the procedure set
forth in Section 3,  "Procedures for Accepting the Offer and Tendering  Shares,"
of the  Offer  to  Purchase.  Share  Certificates  representing  all  physically
tendered  Common  Shares,  or  confirmation  of a book-entry  transfer,  if such
procedure is available, into the Depositary's account at the Book-Entry Transfer
Facility   ("Book-Entry   Confirmation")  of  all  Common  Shares  delivered  by
book-entry  transfer together with a properly completed and duly executed Letter
of  Transmittal  (or facsimile  thereof),  or an Agent's  Message in the case of
book-entry  transfer,  and  any  other  documents  required  by this  Letter  of
Transmittal,  must be received by the Depositary at its address set forth herein
prior to the expiration date of the Offer. If Share  Certificates  are forwarded
to the Depositary in multiple deliveries, a properly completed and duly executed
Letter of Transmittal must accompany each such delivery.

     Stockholders  whose Share Certificates are not immediately  available,  who
cannot deliver their Share  Certificates and all other required documents to the
Depositary on or before the expiration  date of the Offer or who cannot complete
the procedure  for delivery by book-entry  transfer on a timely basis may tender
their Common Shares pursuant to the guaranteed  delivery procedure  described in
Section 3,  "Procedures  for Accepting  the Offer and Tendering  Shares," of the
Offer to Purchase.  Pursuant to such procedure:  (i) such tender must be made by
or through an Eligible Institution;  (ii) a properly completed and duly executed
Notice of Guaranteed  Delivery,  substantially in the form made available by the
Purchaser,  must be received by the Depositary on or before the expiration  date
of the  Offer;  and (iii) the Share  Certificates  representing  all  physically
delivered  Common Shares in proper form for transfer by delivery,  or Book-Entry
Confirmation of all Common Shares delivered by book-entry transfer, in each case
together with a Letter of Transmittal (or facsimile thereof), properly completed
and duly executed,  with any required signature guarantees (or, in the case of a
book-entry  transfer,  an Agent's Message),  and any other documents required by
this Letter of  Transmittal,  must be received by the  Depositary  within  three
trading days after the date of execution of such Notice of Guaranteed  Delivery,
all as described in Section 3, "Procedures for Accepting the Offer and Tendering
Shares," of the Offer to Purchase.

     The term "Agent's  Message" means a message,  transmitted by the Book-Entry
Transfer  Facility to, and received by, the Depositary and forming a part of the
Book-Entry Confirmation,  which states that the Book-Entry Transfer Facility has
received  an  express  acknowledgment  from the  participant  in the  Book-Entry
Transfer Facility tendering the Common Shares that such participant has received
this Letter of Transmittal and agrees to be bound by the terms of this Letter of
Transmittal  and that the  Purchaser  may enforce  such  agreement  against such
participant.

     The method of delivery of this Letter of  Transmittal,  Share  Certificates
and all other  required  documents,  including  delivery  through the Book-Entry
Transfer Facility, is at the option and risk of the tendering  stockholder,  and
the delivery will be deemed made only when actually  received by the  Depositary
(including,  in the case of a book-entry transfer, by Book-Entry  Confirmation).
If delivery is by mail, registered mail with return receipt requested,  properly
insured,  is  recommended.  In all cases,  sufficient  time should be allowed to
ensure timely delivery.

     No alternative,  conditional or contingent  tenders will be accepted and no
fractional  Common  Shares will be  purchased.  By  execution  of this Letter of
Transmittal (or facsimile hereof), all tendering stockholders waive any right to
receive any notice of the acceptance of their Common Shares for payment.

3. Inadequate  Space. If the space provided herein under  "Description of Common
Shares Tendered" is inadequate,  the certificate  numbers,  the number of Common
Shares  represented by such Share  Certificates  and the number of Common Shares
tendered should be listed on a separate schedule and attached hereto.

4. Partial  Tenders (Not  Applicable  to  Stockholders  Who Tender by Book-Entry
Transfer).  If fewer  than all of the  Common  Shares  represented  by any Share
Certificate delivered to the Depositary herewith are to be tendered hereby, fill
in the number of Common Shares which are to be tendered  under "Number of Common
Shares Tendered" in the box entitled "Description of Common Shares Tendered." In
such cases, a new  certificate  representing  the remainder of the Common Shares
that were  represented  by the Share  Certificates  delivered to the  Depositary
herewith will be sent to each person signing this Letter of Transmittal,  unless
otherwise provided in the box entitled "Special Delivery  Instructions"  herein,
as soon as practicable  after the  expiration or  termination of the Offer.  All
Common Shares represented by Share Certificates delivered to the Depositary will
be deemed to have been tendered unless otherwise indicated.

5. Signatures on Letter of Transmittal,  Stock Powers and Endorsements.  If this
Letter of Transmittal is signed by the registered holder(s) of the Common Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on
the  face of the  Share  Certificates  evidencing  such  Common  Shares  without
alteration, enlargement or any other change whatsoever.

     If any  Common  Share  tendered  hereby  is owned of  record by two or more
persons, all such persons must sign this Letter of Transmittal.

     If any of the Common Shares  tendered hereby are registered in the names of
different  holders,  it will be necessary  to complete,  sign and submit as many
separate  Letters of  Transmittal as there are different  registrations  of such
Common Shares.

     If this Letter of Transmittal is signed by the registered  holder(s) of the
Common Shares tendered hereby, no endorsements of Share Certificates or separate
stock  powers  are  required,  unless  payment  is  to  be  made  to,  or  Share
Certificates  not tendered or not  purchased  are to be issued in the name of, a
person  other  than  the  registered   holder(s),   in  which  case,  the  Share
Certificate(s)  representing  the Common Shares tendered hereby must be endorsed
or accompanied by appropriate stock powers, in either case signed exactly as the
name(s)  of the  registered  holder(s)  appear  on  such  Share  Certificate(s).
Signatures on such Share  Certificate(s)  and stock powers must be guaranteed by
an Eligible Institution.

     If this  Letter  of  Transmittal  is  signed  by a  person  other  than the
registered   holder(s)  of  the  Common  Shares  tendered   hereby,   the  Share
Certificate(s)  representing  the Common Shares tendered hereby must be endorsed
or accompanied by appropriate stock powers, in either case signed exactly as the
name(s) of the  registered  holder(s)  appear(s)  on such Share  Certificate(s).
Signatures on such Share  Certificate(s)  and stock powers must be guaranteed by
an Eligible Institution.

     If this Letter of Transmittal  or any  certificate or stock power is signed
by a trustee, executor, administrator, guardian, attorney-in-fact,  officer of a
corporation  or other person acting in a fiduciary or  representative  capacity,
such person should so indicate when signing, and proper evidence satisfactory to
the Purchaser of such person's authority to so act must be submitted.

6. Stock Transfer Taxes. Except as otherwise provided in this Instruction 6, the
Purchaser  will  pay all  stock  transfer  taxes  with  respect  to the sale and
transfer  of any Common  Shares to it or its order  pursuant  to the Offer.  If,
however,  payment of the purchase price of any Common Shares  purchased is to be
made to, or Share  Certificate(s)  representing  Common  Shares not  tendered or
accepted  for payment  are to be issued in the name of, a person  other than the
registered holder(s), the amount of any stock transfer taxes (whether imposed on
the registered holder(s),  such other person or otherwise) payable on account of
the  transfer to such other person will be deducted  from the purchase  price of
such Common Shares purchased,  unless evidence  satisfactory to the Purchaser of
the payment of such taxes, or exemption therefrom, is submitted.

     Except as  provided in this  Instruction  6, it will not be  necessary  for
transfer  tax stamps to be affixed to the Share  Certificates  representing  the
Common Shares tendered hereby.

7. Special Payment and Delivery Instructions.  If a check for the purchase price
of any Common Shares tendered herewith is to be issued, or Share  Certificate(s)
representing  Common Shares not tendered or not  purchased are to be issued,  in
the name of a person other than the person(s) signing this Letter of Transmittal
or if such check or any such Share  Certificate  is to be sent to someone  other
than the  person(s)  signing  this  Letter of  Transmittal  or to the  person(s)
signing this Letter of  Transmittal  but at an address  other than that shown in
the box entitled "Description of Common Shares Tendered" herein, the appropriate
boxes in this Letter of Transmittal must be completed.  Stockholders  delivering
Common Shares tendered  herewith by book-entry  transfer may request that Common
Shares not  purchased be credited to the account  maintained  at the  Book-Entry
Transfer Facility as such stockholder may designate in the box entitled "Special
Payment Instructions" herein. If no such instructions are given, all such Common
Shares not  purchased  will be returned  by  crediting  the same  account at the
Book-Entry  Transfer  Facility as the account from which such Common Shares were
delivered.

8. Waiver of Conditions.  The conditions of the Offer may be waived, in whole or
in part, by the Purchaser, in its sole discretion,  at any time and from time to
time, in the case of any Common Shares tendered.  See Section 10 of the Offer to
Purchase.

9. Lost,  Destroyed or Stolen Certificates.  If any certificate(s)  representing
Common  Shares  has been  lost,  destroyed  or stolen,  the  stockholder  should
promptly  contact  Continental  Stock  Transfer  & Trust  Company,  which is the
Company's  transfer agent and the  Depositary,  by calling (212)  845-3226.  The
stockholder  will then be instructed as to the steps that must be taken in order
to replace the certificate(s).  This Letter of Transmittal and related documents
cannot be processed until the procedures for replacing lost, destroyed or stolen
certificates have been followed.

10.  Questions and Requests for Assistance or Additional  Copies.  Questions and
requests for assistance may be directed to the Information  Agent at its address
or telephone number set forth below. Additional copies of the Offer to Purchase,
this Letter of Transmittal, the Notice of Guaranteed Delivery and the Guidelines
for Certification of Taxpayer  Identification  Number on Substitute Form W-9 may
be obtained  from the  Information  Agent or from brokers,  dealers,  commercial
banks or trust companies.

11.  Substitute Form W-9. Each tendering  stockholder is required to provide the
Depositary  with  a  correct  Taxpayer  Identification  Number  ("TIN")  on  the
Substitute Form W-9 which is provided under "Important Tax  Information"  below,
and to certify, under penalties of perjury, that such number is correct and that
such stockholder is not subject to backup  withholding of Federal income tax. If
a tendering  stockholder has been notified by the Internal  Revenue Service that
such stockholder is subject to backup  withholding,  such stockholder must cross
out item (2) of the  Certification  box of the Substitute  Form W-9, unless such
stockholder  has since been notified by the Internal  Revenue  Service that such
stockholder is no longer subject to backup  withholding.  Failure to provide the
information on the Substitute Form W-9 may subject the tendering  stockholder to
a $200 penalty imposed by the Internal Revenue Service and to 31% Federal income
tax  withholding  on the  payment of the  purchase  price of all  Common  Shares
purchased  from such  stockholder.  If the  tendering  stockholder  has not been
issued a TIN and has  applied  for one or  intends  to apply for one in the near
future,  such  stockholder  should write "Applied For" in the space provided for
the TIN in Part I of the  Substitute  Form W-9, and sign and date the Substitute
Form W-9 and the  Certificate of Awaiting  Taxpayer  Identification  Number.  If
"Applied For" is written in Part I and the Depositary is not provided with a TIN
within 60 days, the Depositary will withhold 31% on all payments of the purchase
price  to such  stockholder  until a TIN is  provided  to the  Depositary.  Each
foreign stockholder must complete and submit Form W-8 in order to be exempt from
the 31% Federal  income tax backup  withholding  due on payments with respect to
the Common Shares.

12. Non-United States Holders. Non-United States holders must submit a completed
IRS W-8BEN in order to qualify as an exempt  recipient.  IRS Form  W-8BEN may be
obtained by contacting  the Depositary at its address on the face of this Letter
of Transmittal.

     Important:  This  Letter  of  Transmittal  (or  manually  signed  facsimile
thereof),  together with any required signature guarantees, or, in the case of a
book-entry transfer,  an Agent's Message, and any other required documents,  and
either  Share  Certificates  for  tendered  Common  Shares  or  confirmation  of
book-entry  transfer must be received by the  Depositary,  in each case prior to
the expiration date of the Offer,  which is 5:00 P.M., Eastern Time, on Tuesday,
May 23, 2000 (unless  otherwise  extended),  or the tendering  stockholder  must
comply with the procedures for guaranteed delivery.

                            IMPORTANT TAX INFORMATION

     Under the  Federal  income tax law, a  stockholder  whose  tendered  Common
Shares are accepted for payment is required by law to provide the Depositary (as
payer) with such stockholder's correct TIN on Substitute Form W-9 below. If such
stockholder  is an individual,  the TIN is such  stockholder's  social  security
number.  If the Depositary is not provided with the correct TIN, the stockholder
may be subject to a $200  penalty  imposed by the Internal  Revenue  Service and
payments  that  are made to such  stockholder  with  respect  to  Common  Shares
purchased pursuant to the Offer may be subject to backup withholding of 31%.

     Certain stockholders (including, among others, all corporations and certain
foreign  individuals) are not subject to these backup  withholding and reporting
requirements.  In  order  for a  foreign  individual  to  qualify  as an  exempt
recipient,  such individual must submit a Form W-8BEN, signed under penalties of
perjury,  attesting to such  individual's  exempt  status.  A Form W-8BEN can be
obtained from the  Depositary.  Exempt  stockholders  should  furnish their TIN,
check the box and write  "Exempt"  in Part II of the  Substitute  Form W-9,  and
sign,  date  and  return  the  Substitute  Form W-9 to the  Depositary.  See the
enclosed  Guidelines  for  Certification  of Taxpayer  Identification  Number on
Substitute Form W-9 for additional  instructions.  A stockholder  should consult
his or her tax advisor as to such  stockholder's  qualification for an exemption
from backup withholding and the procedure for obtaining such exemption.

     If backup withholding  applies,  the Depositary is required to withhold 31%
of any payments made to the stockholder. Backup withholding is not an additional
tax.  Rather,  the Federal  income tax  liability  of persons  subject to backup
withholding  will be  reduced  by the  amount of tax  withheld.  If  withholding
results in an  overpayment  of taxes, a refund may be obtained from the Internal
Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

     To prevent  backup  withholding  on payments that are made to a stockholder
with respect to Common Shares  purchased  pursuant to the Offer, the stockholder
is  required  to notify the  Depositary  of such  stockholder's  correct  TIN by
completing  the form below  certifying  that (a) the TIN provided on  Substitute
Form W-9 is correct  (or that such  stockholder  is awaiting a TIN) and (b) that
(i) such  stockholder has not been notified by the Internal Revenue Service that
such  stockholder  is subject to backup  withholding as a result of a failure to
report all  interest  or  dividends  or (ii) the  Internal  Revenue  Service has
notified such  stockholder  that such stockholder is no longer subject to backup
withholding.

WHAT NUMBER TO GIVE THE DEPOSITARY

     The  stockholder  is required to give the  Depositary  the social  security
number or  employer  identification  number of the  record  holder of the Common
Shares  tendered  hereby.  If the Common Shares are in more than one name or are
not in the  name of the  actual  owner,  consult  the  enclosed  Guidelines  for
Certification  of  Taxpayer  Identification  Number on  Substitute  Form W-9 for
additional guidance on which number to report. If the tendering  stockholder has
not been  issued a TIN and has  applied  for a number or  intends to apply for a
number in the near future,  the  stockholder  should write  "Applied For" in the
space provided for the TIN in Part I, and sign and date the Substitute  Form W-9
and the Certificate of Awaiting Taxpayer Identification Number. If "Applied For"
is written in Part I and the  Depositary  is not  provided  with a TIN within 60
days, the Depositary  will withhold 31% of all payments of the purchase price to
such stockholder until a TIN is provided to the Depositary.

To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

     We are asking  you to  contact  your  clients  for whom you hold  shares of
Common Stock, par value $0.001 per share (the "Common Shares"),  of CSI Computer
Specialists, Inc., a Delaware corporation (the "Company"). Please bring to their
attention as promptly as possible the offer being made by  Interactive  Systems,
Inc. (the  "Purchaser")  to purchase all of the  outstanding  Common Shares at a
purchase  price of $1.00 per Common  Share,  net to the seller in cash (less any
required  withholding  taxes),  without  interest  thereon,  upon the  terms and
subject to the  conditions  set forth in the Offer to Purchase,  dated April 26,
2000 (the "Offer to Purchase")  and in the related  letter of  transmittal  (the
"Letter of Transmittal," which,  together with the Offer to Purchase, as amended
or supplemented from time to time, collectively constitute the "Offer") enclosed
herewith.

     Please  furnish  copies of the enclosed  materials to those of your clients
for whose accounts you hold Common Shares registered in your name or in the name
of your nominee.

     The Board of Directors  of the Company has  determined  that,  based on the
Company's current financial condition, its inability to obtain financing for its
operations,  recent bid prices for the Common  Shares on the OTC Bulletin  Board
and the Company's  current book value, the Offer is in the best interests of the
Company  and its  stockholders,  and  has  voted  to  recommend  to the  Company
stockholders  acceptance  of the Offer.  The Board of  Directors  of the Company
recommends that the Company's  stockholders  tender their Common Shares pursuant
to the Offer.

     Enclosed  herewith for your  information and forwarding to your clients are
copies of the following documents:

1.       The Offer to Purchase, dated April 26, 2000.

2.       The Letter of Transmittal  for your use to tender Common Shares and for
         the  information  of your  clients.  Facsimile  copies of the Letter of
         Transmittal may be used to tender Common Shares.

3.       A printed  form of letter  which may be sent to your  clients for whose
         accounts you hold Common Shares  registered in your name or in the name
         of your  nominee,  with space  provided  for  obtaining  such  clients'
         instructions with regard to the Offer.

4.       The Notice of  Guaranteed  Delivery for Shares to be used to accept the
         Offer if certificates for Common Shares ("Share  Certificates") and all
         other  required  documents are not  immediately  available or cannot be
         delivered  to   Continental   Stock   Transfer  &  Trust  Company  (the
         "Depositary")  by the  Expiration  Date  (as  defined  in the  Offer to
         Purchase)  or if  the  procedure  for  book-entry  transfer  cannot  be
         completed by the Expiration Date.

5.       A letter to  stockholders  from  William F.  Pershin,  President of the
         Company,  accompanied  by  the  Company's   Solicitation/Recommendation
         Statement on Schedule 14D-9.

6.       Guidelines  of  the  Internal  Revenue  Service  for  Certification  of
         Taxpayer Identification Number on Substitute Form W-9.

     Your prompt  action is  requested.  We urge you to contact  your clients as
promptly  as  possible.  Please note that the Offer and  withdrawal  rights will
expire at 5:00 P.M., Eastern Time, on Tuesday, May 23, 2000, unless the Offer is
extended.

     In order to accept the Offer, a duly executed and properly completed Letter
of Transmittal and any required signature guarantees,  or an Agent's Message (as
defined in the Offer to Purchase) in  connection  with a book-entry  delivery of
Common Shares, and any other required documents should be sent to the Depositary
and either Share Certificates  representing the tendered Common Shares should be
delivered to the  Depositary,  or Common Shares should be tendered by book-entry
transfer into the  Depositary's  account  maintained at the Book Entry  Transfer
Facility (as  described in the Offer to Purchase),  all in  accordance  with the
instructions set forth in the Offer.

     If holders of Common  Shares wish to tender,  but it is  impracticable  for
them to forward their Share Certificates or other required documents on or prior
to the Expiration Date or to comply with the book-entry transfer procedures on a
timely  basis,  a tender may be effected by following  the  guaranteed  delivery
procedures  specified  in Section 3,  "Procedures  for  Accepting  the Offer and
Tendering Shares," of the Offer to Purchase.

     The Purchaser will not pay any commissions or fees to any broker, dealer or
other  person  (other  than  the  Depositary  and  the  Information  Agent)  for
soliciting  tenders of Common Shares pursuant to the Offer.  The Purchaser will,
however, upon request, reimburse you for customary clerical and mailing expenses
incurred by you in forwarding any of the enclosed materials to your clients. The
Purchaser  will pay or cause to be paid any stock  transfer taxes payable on the
transfer of Common Shares to it, except as otherwise  provided in  Instruction 6
of the Letter of Transmittal.

to, and  additional  copies of the enclosed  material may be obtained  from, the
Information  Agent at its  address  and  telephone  number set forth on the back
cover of the Offer to Purchase.

                            Interactive Systems, Inc.

     Nothing contained herein or in the enclosed  documents shall constitute you
or any other person the agent of the Purchaser,  the Company,  the Depositary or
the Information  Agent, or any affiliate of any of them, or authorize you or any
other person to make any  statement or use any document on behalf of any of them
in  connection  with  the  Offer  other  than  the  enclosed  documents  and the
statements contained therein.

To Our Clients:

     Enclosed for your consideration are the Offer to Purchase,  dated April 26,
2000 (the "Offer to  Purchase"),  and the  related  letter of  transmittal  (the
"Letter of Transmittal,"  which together with the Offer to Purchase,  as amended
or supplemented from time to time, collectively constitute the "Offer") relating
to  the  offer  by  Interactive  Systems,  Inc.,  a  Virginia  corporation  (the
"Purchaser"),  to purchase all  outstanding  shares of Common  Stock,  par value
$0.001 per share (the "Common  Shares"),  of CSI Computer  Specialists,  Inc., a
Delaware  corporation (the  "Company"),  at a purchase price of $1.00 per Common
Share, net to the seller in cash (less any required withholding taxes),  without
interest thereon,  upon the terms and subject to the conditions set forth in the
Offer.  Holders of Common Shares whose  certificates for such Common Shares (the
"Share Certificates") are not immediately available, or who cannot deliver their
Share  Certificates  and all  other  required  documents  to  Continental  Stock
Transfer & Trust Company (the  "Depositary")  on or prior to the Expiration Date
(as defined in the Offer to Purchase), or who cannot complete the procedures for
book-entry transfer on a timely basis, must tender their Common Shares according
to the  guaranteed  delivery  procedures  set forth in Section 3 of the Offer to
Purchase.

     WE ARE THE HOLDER OF RECORD OF COMMON SHARES HELD BY US FOR YOUR ACCOUNT. A
TENDER OF SUCH COMMON  SHARES CAN BE MADE ONLY BY US AS THE HOLDER OF RECORD AND
PURSUANT TO YOUR INSTRUCTIONS. THE LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR
YOUR  INFORMATION ONLY AND CANNOT BE USED BY YOU TO TENDER COMMON SHARES HELD BY
US FOR YOUR ACCOUNT.

     Accordingly,  we request  instructions  as to  whether  you wish to have us
tender on your  behalf  any or all  Common  Shares  held by us for your  account
pursuant to the terms and conditions set forth in the Offer.

     Please note the following:

1.       The tender price is $1.00 per Common Share, net to you in cash, without
         interest  thereon,  upon the terms and  subject to the  conditions  set
         forth in the Offer.

2.       The Offer is being made for all  outstanding  Common Shares not already
         owned by Donald C. Weymer,  the  Purchaser's  founder,  Chief Executive
         Officer, President, a Director and 98% shareholder.

3.       The Board of Directors of the Company has determined that, based on the
         Company's  current  financial   condition,   its  inability  to  obtain
         financing for its  operations,  recent bid prices for the Common Shares
         on the OTC Bulletin  Board and the  Company's  current book value,  the
         Offer is in the best interests of the Company and its  stockholders and
         has voted to recommend to the Company  stockholders  acceptance  of the
         Offer.  The  Board of  Directors  of the  Company  recommends  that the
         Company's  stockholders  tender  their  Common  Shares  pursuant to the
         Offer.

4.       The Offer is subject to certain customary closing  conditions set forth
         in the Offer to Purchase. See Section 10, "Conditions of the Offer," of
         the Offer to Purchase.

5.       Any stock transfer taxes applicable to the sale of Common Shares to the
         Purchaser  pursuant to the Offer will be paid by the Purchaser,  except
         as otherwise provided in Instruction 6 of the Letter of Transmittal.

6.       The Offer and withdrawal rights will expire at 5:00 P.M., Eastern Time,
         on Tuesday, May 23, 2000, unless the Offer is extended.

               7. Payment for Common Shares purchased pursuant to the Offer will
               in all cases be made only after timely  receipt by the Depositary
               of  (a)  Share   Certificates  or  timely   confirmation  of  the
               book-entry  transfer  of such  Common  Shares  into  the  account
               maintained by the  Depositary at The  Depository  Trust  Company,
               pursuant to the  procedures  set forth in Section 3,  "Procedures
               for Accepting  the Offer and  Tendering  Shares," of the Offer to
               Purchase, (b) the Letter of Transmittal (or a facsimile thereof),
               properly completed and duly executed, with any required signature
               guarantees  or an  Agent's  Message  (as  defined in the Offer to
               Purchase),  in connection with a book-entry delivery, and (c) any
               other   documents   required   by  the  Letter  of   Transmittal.
               Accordingly,   payment   may  not  be   made  to  all   tendering
               stockholders  at  the  same  time,   depending  upon  when  Share
               Certificates  or  confirmations  of  book-entry  transfer of such
               Common  Shares  into the  Depositary's  account  at a  Book-Entry
               Transfer Facility are actually received by the Depositary.

     If you wish to have us tender  any or all of the Common  Shares  held by us
for your account, please so instruct us by completing,  executing, detaching and
returning to us the instruction  form set forth on the last page of this letter.
If you authorize the tender of your Common  Shares,  all such Common Shares will
be tendered  unless  otherwise  specified  on the last page of this  letter.  An
envelope to return your instructions to us is enclosed. YOUR INSTRUCTIONS SHOULD
BE  FORWARDED TO US IN AMPLE TIME TO PERMIT US TO SUBMIT A TENDER ON YOUR BEHALF
PRIOR TO THE EXPIRATION OF THE OFFER.

     The  Purchaser  is not aware of any state  where the making of the Offer is
prohibited  by  administrative  or judicial  action  pursuant to any valid state
statute.  If the Purchaser becomes aware of any valid state statute  prohibiting
the making of the Offer or the acceptance of the Common Shares pursuant thereto,
the Purchaser  will make a good faith effort to comply with such statute or seek
to have such statute  declared  inapplicable  to the Offer.  If, after such good
faith effort,  the Purchaser  cannot comply with such state  statute,  the Offer
will not be made to (nor will tenders be accepted  from or on behalf of) holders
of Common Shares in such state.

 Interactive Systems, Inc. Mails Tender Offer for CSI Computer Specialists, Inc.

                 Common Stock for $1.00 Per Share in Cash

         Arlington,  Virginia  and  Gaithersburg,  Maryland,  April 26,  2000 --

that  the  tender  offer  is in  the  best  interests  of  the  Company  and  it
shareholders,   and  has  voted  to  recommend  to  the  Company's  stockholders
acceptance  of the Offer.  CSI Computer  Specialists,  Inc.'s Board of Directors

may be situated and remove the same  therefrom  without any  liability for suit,
action or other proceeding by Borrower,  BORROWER and its SUBSIDIARIES,  if any,
HEREBY  WAIVING ANY AND ALL RIGHTS TO PRIOR NOTICE AND TO JUDICIAL  HEARING WITH

license) upon such terms and under such  conditions  at Bank, in its  reasonable
discretion,  may  determine,  all without any notice or demand,  and purchase or

extent  permitted  by  applicable  law.  (e) With  respect  to any  instruments,

<PAGE>


directly  to Bank,  take  control  of the cash and  non-cash  proceeds  thereof,
demand,  collect,  sue for and  receive  any money or  property at any time due,

substitution,  with authority to receive, open and dispose of all mail addressed
to Borrower, to notify the postal authorities to change the address for delivery
of mail  addressed  to  Borrower  and its  Subsidiaries,  if any,  to such other

judgment  or  mistake  of fact or law,  except  for  gross  negligence,  willful
misconduct or bad faith.  This Power of Attorney is coupled with an interest and
is irrevocable so long as any of the Obligations remain unpaid or unperformed or
there  exists any  commitment  of Bank to Borrower  which could give rise to any
Obligations. 9.03 Cumulative Nature of Remedies. Each right, power and remedy of
Bank shall be cumulative and  concurrent,  and recourse to one or more rights or
remedies shall not constitute a waiver of any other right,  power or remedy.  It
is mutually agreed that commercial reasonableness and good faith require Bank to

place of any public disposition of the Collateral or of the time after which any

action  thereon  as the Bank may  consider  necessary  or  appropriate  for such
purpose.  All sums so paid or  advanced  by the Bank (the  "Expense  Payments"),

premises or taxes and the  satisfaction or discharge of any judgment or any Lien
upon the Collateral or other property or assets of Borrower;  provided, however,
that the making of any such  advance by Bank  shall not  constitute  a waiver by
Bank of any Event of Default  with  respect  to which  such  advance is made nor
relieve  Borrower of any such Event of Default.  Borrower shall pay to Bank upon
demand  all such  advances  made by Bank with  interest  thereon at the rate and
determined in the manner  provide in the Note. All such advances shall be deemed
to be included in the Obligations and secured by the security  interest  granted

Collateral;  (d)  In  the  event  Bank  seeks  to  repossess  any  or all of the

remedies  hereunder  and under the Other  Agreements  without  resorting  to and
without regard to any  collateral  security or sources of liability with respect
to any of the  Obligations.  10.07 Waivers by Bank.  Neither any failure nor any
delay on the part of Bank in  exercising  right,  power or remedy  hereunder  or

including, without limitation, any funds in any checking or other account now or
hereafter  maintained by Borrower at Bank. Borrower hereby confirms Bank's right

                       (SECURED REVOLVING LINE OF CREDIT)

         FOR VALUE  RECEIVED,  the  undersigned,  INTERACTIVE  SYSTEMS,  INC., a
Maryland   corporation  and  NATIONAL  CONVERSION  SYSTEMS,   INC.,  a  Virginia
corporation  (collectively,  the  "Borrower"),  promises  to pay to the order of
SANDY SPRING NATIONAL BANK OF MARYLAND,  a national  banking  association,  with
offices at 17801 Georgia  Avenue,  Olney,  Maryland  20832,  its  successors and
assigns,  (the "Lender") at such offices or at such other place or places as the
Lender may from time to time  designate in writing,  the  principal  sum of FOUR
MILLION AND NO/100 DOLLARS  ($4,000,000.00),  together with interest at the rate
hereinafter  provided  until paid,  said principal and interest being payable as
follows: (a) Interest shall accrue hereunder at the rate of One Percent (1%) per
annum above the Lenders  "Prime Rate of Interest"  (as such term is  hereinafter
defined  below),  on so much of the  principal  as  shall  from  time to time be
advanced and/or  re-advanced  and remain unpaid,  and interest only shall be due
and  payable  monthly  commencing  on the first  (1st)  day of the  first  (1st)
calendar month  following the date hereof and continuing on the same day of each
and every calendar month thereafter; and

(b) If not sooner paid, the entire balance of principal  remaining unpaid,  plus
interest  accrued  thereon at the aforesaid rate not previously  paid,  fees and
costs, if any, shall be due and payable in full on June 30, 2001.

         For  purposes  of  computing  interest  on the debt  evidenced  hereby,
interest  shall be  calculated  on the basis of a three  hundred sixty (360) day
calendar  year.  Payments  made on account  hereof shall be applied first to the
payment of late fees,  then to the payment of accrued and unpaid  interest,  and
the remainder shall be credited to principal.

         As used in this Note the expression  "Prime Rate of Interest"  shall be
defined as the rate of interest  from time to time  established  and publicly or
privately  announced by the Lender as its then applicable prime rate of interest
to be used as an index in  determining  actual  interest  rates to be charged to
certain  borrowers  of the  Lender.  The  rate of  interest  hereunder  shall be
adjusted as and when any change in the "Prime Rate of Interest" shall occur. The
Lender may establish and  reestablish  the "Prime Rate of Interest" from time to
time in its sole  discretion,  it being understood and agreed that (1) such rate
is intended merely as an index for setting interest rates of the Lender, and (2)
the  particular  borrower  may be more than,  equal to, or less than such index;
provided, however, that at no time shall the rate of interest applicable to this
Note exceed the highest rate permissible under applicable laws.

         If default be made in the payment of any  installment  of  principal or
interest due under this Note,  and such default  shall  continue for a period of
ten (1) days after notice to the Borrower, the entire principal sum outstanding,
together with accrued  interest  thereon,  fees and costs, if any, shall at once
become due and payable at the option of the Lender without  further  notice.  If
default be made in the  performance  of any covenant of either (a) the Indemnity
Deed of Trust and  Security  Agreement  made by Donald C.  Weymer to secure  the
Lender  dated July 30, 1999,  and recorded on September  21, 1999 among the Land
Records of Montgomery County, Maryland in Liber 17507, at folio


<PAGE>


276, or (b) the Amended and Restated Loan and Security Agreement given to secure
this  Note,  or  in  any  of  the  documents  listed  in  Section  5.03  thereof
(collectively,  the "Security Documents") (the terms and provisions of which are
incorporated  herein by this  reference  as if set  forth in full),  and if such
default shall continue for the duration of any  applicable  grace period therein
contained, the entire principal sum outstanding,  together with accrued interest
thereon,  shall at once  become  due and  payable  at the  option of the  Lender
without further  notice.  Failure to exercise such option shall not constitute a
waiver of the right to exercise the same in the event of any subsequent default.
Acceleration  of  maturity,  once  claimed by the  Lender,  may at its option be
rescinded by an  instrument in writing to that effect;  however,  the tender and
acceptance  of a partial  payment or partial  performance  shall not, by itself,
affect or rescind such acceleration of maturity.

         In the event  any  installment  due  under  this Note is paid more than
fifteen (15) days after the date when the same is due,  then the Lender shall be
entitled to collect a "late charge" in an amount equal to one-twentieth (1/20th)
of such installment.

         In the event it shall  become  necessary  to employ  counsel to collect
this  obligation or to protect the security  hereof,  the Borrower agrees to pay
reasonable  attorney's fees, whether suit be brought or not, and all other costs
and  expenses  reasonably  connected  with  collection,  the  protection  of the
security,  the defense of any counterclaim,  the enforcement  (including without
limitation,  as a part of any proceeding brought under the Bankruptcy Reform Act
of 1978, as amended) of any remedies herein provided for, or provided for in the
Security Documents given to secure this Note.

         The  privilege  is  reserved  to  prepay  the  principal   indebtedness
evidenced hereby, in whole or in part, at any time, without premium or penalty.

         The Borrower and any  endorsers,  guarantors  and sureties  jointly and
severally waive presentment,  protest and demand,  notice of protest,  notice of
dishonor,  demand and  dishonor,  and any and all lack of diligence or delays in
the collection or enforcement  hereof and expressly agree that this Note, or any
payment  hereunder,  may be  extended  from  time  to  time  without  in any way
affecting  the  liability of the Borrower or any  endorser,  guarantor or surety
hereof.  Borrower  also waives any right to trial by jury fully with  respect to
each  instance and each issue as to which the right to a jury trial shall now or
hereafter exist hereunder.

         The validity and  construction of this Note and all matters  pertaining
thereto are to be determined according to the laws of the State of Maryland.

         In the event any provision of this Note (or any part of any  provision)
is  held  by a  court  of  competent  jurisdiction  to be  invalid,  illegal  or
unenforceable in any respect,  such invalidity,  illegality or  unenforceability
shall  not  affect  any  other  provision  (or  remaining  part of the  affected
provision) of this Note;  but this Note shall be as if such invalid,  illegal or
unenforceable  provision (or part thereof) had not been  contained in this Note,
but only to the extent it is invalid, illegal or unenforceable.

         All  notices,  demands,  requests  and  other  communications  required
pursuant to the  provisions of this Note or the Security  Documents  shall be in
writing  and  shall be  deemed to have  been  properly  given or served  for all
purposes  when  presented  personally  or sent by United  States  Registered  or
Certified Mail - Return Receipt Requested,  postage prepaid, to the Borrower at:
1777 N. Kent Street, Suite 1103, Arlington, Virginia 22209; and to the Lender at
the address  stated in the first  paragraph of this Note. The Lender or Borrower
may  designate  a change of address  by notice in  writing  to the other  party.
Whenever in this Note the giving of notice by mail or otherwise is required, the
giving of such notice may be waived in writing by the person entitled to receive
such notice.

         It is the intention of the Borrower and the Lender to conform  strictly
to applicable usury laws. Accordingly,  if the transactions  contemplated hereby
would be  usurious  under  applicable  law  (including  the laws of the State of
Maryland  and the laws of the United  States of  America)  then,  in that event,
notwithstanding  anything  to the  contrary  in any  agreement  entered  into in
connection with or as security for this Note, it is agreed that the aggregate of
all  consideration  which  constitutes  interest  under  applicable  law that is
contracted  for,  charged or received  under this Note or under any of the other
aforesaid  agreements or otherwise in  connection  with this Note shall under no
circumstances  exceed the maximum amount of interest  allowed by applicable law,
and any excess shall be credited,  first, on fees and costs, if any, due on this
Note and, secondly, on the principal balance due on this Note by the Lender (or,
if this Note shall have been paid in full, refunded to the Borrower).

         As used in this Note,  the  singular  shall  include the plural and the
plural shall include the singular, where the context shall so require.

         This  Note  shall be the joint and  several  obligation  of each of the
makers  hereof  (if more than one) and shall  apply to and bind them and each of
them and  their  respective  heirs,  successors,  personal  representatives  and
assigns.

         So long as the loan indebtedness evidenced by this Note remains unpaid,
the  Borrower  agrees to provide  the Lender  with such other  information  with
respect to the financial  statements of the Borrower as the Lender may from time
to time require.

         SHOULD ANY SUMS BECOME DUE AND PAYABLE  HEREUNDER,  AND SUCH SUM IS NOT
PAID WHEN AND AS DUE,  TIME BEING OF THE ESSENCE,  THE BORROWER  AUTHORIZES  ANY
ATTORNEY ADMITTED TO PRACTICE BEFORE ANY COURT OF RECORD IN THE UNITED STATES TO
CONFESS JUDGMENT ON BORROWER'S BEHALF OF THE FULL SUM DUE HEREON PLUS REASONABLE
ATTORNEYS' FEES, AND, UPON THE ENTRY OF JUDGMENT, BORROWER WAIVES THE BENEFIT OF
ANY AND EVERY STATUTE,  ORDINACE,  OR RULE OF COURT WHICH MAY BE LAWFULLY WAIVED
CONFERRING UPON BORROWER ANY RIGHT OR PRIVILEGE OR EXEMPTION,  STAY OF EXECUTION
OR SUPPLEMENTARY PROCEEDINGS,  OR OTHER RELIEF FROM THE ENFORCEMENT OR IMMEDIATE
ENFORCEMENT  OF A  JUDGMENT  OR  RELATED  PROCEEDINGS  ON A  JUDGMENT.  BORROWER
CONSENTS  TO  VENUE  IN ANY  COUNTY  IN THE  STATE  OF  MARYLAND  OR THE CITY OF
BALTIMORE  WITH  RESPECT TO THE  INSTITUTION  OF AN ACTION  CONFESSING  JUDGMENT
HEREON,  REGARDLESS  OF WHERE  VENUE WOULD  OTHERWISE  BE PROPER.  ANY  JUDGMENT
ENTERED  AGAINST  BORROWER,  WHETHER  BY  CONFESSION  OR  OTHERWISE,  SHALL BEAR
INTEREST AT A RATE WHICH IS THE HIGHEST RATE OF INTEREST  BEING PAID BY BORROWER
ON THE DATE OF  JUDGMENT.  THE  AUTHORITY  AND  POWER TO  APPEAR  FOR AND  ENTER
JUDGMENT  AGAINST  BORROWER  SHALL  NOT BE  EXHAUSTED  BY ONE OR MORE  EXERCISES
THEREOF, OR BY ANY IMPERFECT EXERCISE THEREOF,  AND SHALL NOT BE EXTINGUISHED BY
ANY JUDGMENT ENTERED PURSUANT THERETO; SUCH AUTHORITY AND POWER MAY BE EXERCISED
ON ONE  OR  MORE  OCCASIONS,  FROM  TIME  TO  TIME,  IN THE  SAME  OR  DIFFERENT
JURISDICTIONS  AS OFTEN AS THE LENDER OR ITS  ASSIGNS  SHALL DEEM  NECESSARY  OR
ADVISABLE UNTIL ALL SUMS DUE HEREUNDER HAVE BEEN PAID IN FULL.

         It is  understood  and agreed that in the event a default  exists under
any  other  loan  held by the  Lender in which  the  Borrower  or any  guarantor
therefor is a borrower or a  guarantor  thereunder,  then the Lender may, at its
option,  declare the entire  indebtedness  evidenced hereby  immediately due and
payable.

         The Borrower  hereby warrants and represents that the loan evidenced by
this Note and was made for  acquiring  or carrying  on a business or  commercial
enterprises.

         Time is of the essence of all provisions of this Note.

         It is  contemplated  that by reason of prepayments  hereon there may be
times  when  no  indebtedness  is  owing  hereunder;  but  notwithstanding  such
occurrences,  this Note  shall be in full  force and  effect  as  advances  made
pursuant to and under the terms of this Note subsequent to each occurrence.

         In the event that the unpaid  principal  amount hereof at any time, for
any reason,  exceeds the maximum  amount  hereinabove  specified,  the  Borrower
covenants and agrees to pay the excess  principal  amount forthwith upon demand;
such  excess  principal  amount  shall in all  respects be deemed to be included
among the advances  made pursuant to the other terms of this Note and shall bear
interest at the rate or rates hereinabove stated.

         The  proceeds  of the loan  evidenced  hereby are to be  advanced  on a
revolving  credit basis pursuant to the "Borrowing Base" provisions set forth in
the aforesaid Amended and Restated Loan and Security Agreement. Any amounts from
time to time paid on account of the principal  indebtedness evidenced hereby may
be  re-advanced  to the Borrower  pursuant to (and subject to the provisions and
limitations  of) this  Note and the  aforesaid  Amended  and  Restated  Loan and
Security Agreement.  The aggregate principal  indebtedness  evidenced hereby may
increase or decrease from time to time;  provided,  however,  that the aggregate
principal indebtedness evidenced hereby at any one time shall not exceed the sum
of FOUR MILLION AND NO/100 DOLLARS ($4,000,000.00).

         This Note is a restatement  and  modification  of a certain  Promissory
Note (Secured  Revolving  Line of Credit),  dated July 30, 1999, to the order of
Lender,  evidencing a loan in the original  principal  amount of Two Million and
No/100 Dollars  ($2,000,000.00)  (the "Original Note"),  secured by the Security
Documents.   Nothing   herein-contained   shall  be  deemed  a  novation  as  to
indebtedness evidenced by the Original Note, as restated and modified.

         Re:   Consent regarding various provisions of the Amended and Restated

             Loan and Security Agreement between Interactive Systems, Inc. and

                  Sandy Spring National

                  Bank

Dear Ms. Roberts:

         The purpose of this letter is to request  your  consent  under  certain
provisions  of  the  Amended  and  Restated  Loan  Agreement   entered  into  by
Interactive Systems, Inc. ("ISI") and Sandy Spring National Bank (the "Bank") on
March 30, 2000 (the "Agreement"), to a tender offer, which ISI will undertake in
order to acquire control of CSI Computer Specialists, Inc. ("CSI")

Plans of ISI:

         ISI hereby  advises the Bank that it  anticipates  commencing  a tender
offer for all of the  outstanding  common stock of CSI not already  owned by Mr.
Donald C. Weymer,  ISI's  founder,  Chief  Executive  Officer,  Director and 98%
shareholder, in April 2000 (the "Offer"). The Offer is intended to enable ISI to
acquire  control of, and the entire equity  interest in CSI. Upon  completion of
the Offer, ISI intends to operate CSI as a majority-owned subsidiary of ISI.

         If the CSI  stockholders  do not tender all of their common stock,  ISI
intends to evaluate  whether,  under the circumstances at that time, it would be
in the best interest of ISI and CSI to acquire  additional common stock by means
of a second tender offer, merger or other transaction.

         ISI  expects to use a portion of the funds from the  revolving  line of
credit under the Agreement to purchase the common stock.

Related Provisions in the Agreement:

1)       Section 2.02. Manner of Borrowing and Disbursement of Revolving Loan.

         Section 2.02 of the Agreement  provides that,  before each disbursement
         under the line of credit, ISI is required to submit to the Bank for its
         approval  a written  statement  of the  purpose  of such  disbursement,
         together with a contemplated source of repayment of the disbursement.

         Under  Section  2.02  of  the  Agreement,  ISI  hereby  requests  up to
         $1,100,000  for the  purpose  of  purchasing  the  common  stock of CSI
         Computer  Services,  Inc. through the transaction  described above. ISI
         intends to repay the funds  borrowed for the Offer from the  collection
         of receivables.

2) Section 7.03. Merger, Sale of Assets, Etc.

         Section 7.03 of the Agreement  provides that ISI must obtain the Bank's
         written  consent  in order to enter  into or be a party to a merger  or
         consolidation, or purchase or otherwise acquire any shares of stock of,
         or similar interest in any other person.

         Under  Section 7.03 of the  Agreement,  ISI hereby  requests the Bank's
         consent regarding the transactions described above;  specifically,  the
         purchase of common stock of CSI through the Offer and, if necessary,  a
         second tender offer, merger or other consolidation with CSI.

3)       Section 7.07. Subsidiaries.

         Section 7.07 of the Agreement provides that ISI may not form or acquire
         any subsidiaries without the prior written consent of the Bank.

         Under  Section 7.07 of the  Agreement,  ISI hereby  requests the Bank's
         consent to acquire and operate CSI as a majority-owned subsidiary.

         If you have any questions about this Consent  Letter,  please feel free
to call Robert V. Windley at (703) 247-1223, or our counsel, Jeffrey B. Grill at
(202) 663-9201. If you do not have any questions,  please sign this letter below
evidencing  your consent  under the  Agreement to the  proposed  actions  listed
herein and return the original of this consent  letter as soon as possible.  The
enclosed copy is for your records.

Sincerely,

/s/ Donald C. Weymer
