                           currently contemplated that Shmuel BenTov and Reuven
                           Battat will resign from TACT's Board of Directors
                           prior to the consummation of the Share Exchange
                           Transaction, thereby leaving 2 remaining directors,
                           i.e., Steven Mukamal and William Miller.

                  (3)      Following the consummation of the Exchange
                           Transaction, the remaining directors Steven Mukamal
                           and William Miller will elect Andrew Harry Ball and
                           William A. Newman to fill the vacancies created by
                           the resignations of Shmuel BenTov and Reuven Battat.
                           It is contemplated that a fifth director Joseph
                           Harris, who will be independent, will also be
                           elected. It is currently contemplated that five

                  (4)      Following consummation of the Exchange Transaction,
                           Vanguard's Chief Executive Officer will assume the
                           role of Chief Executive Officer of TACT.

                  (5)      Shmuel BenTov, TACT's current Chief Executive
                           Officer, will remain with TACT in a business
                           development and advisory role and his existing
                           employment agreement will be amended in a manner
                           consistent with the foregoing.

         (j)      CHANGE OF TACT'S NAME FROM "THE A CONSULTING TEAM, INC." TO

                  (1)      On January 20, 2005, TACT's Board of Directors voted
                           to approve the change of TACT's name from "The A

                  (2)      The Name Change requires the approval of the holders
                           of a majority of the TACT Common Shares.

         (k)      DECLARATION OF CASH DIVIDEND TO SHAREHOLDERS OF ISSUED AND
                  OUTSTANDING COMMON STOCK AND PREFERRED STOCK OF TACT: On
                  January 20, 2005, TACT's Board of Directors voted to approve
                  the declaration of a cash dividend of $0.75 per share on the
                  shares of issued and outstanding TACT Common Shares and TACT
                  preferred stock to the holders of record of such TACT Common
                  Shares and TACT preferred stock as of a date to be determined
                  subsequently by TACT's Board of Directors (hereinafter the
                  "Dividend"). The payment of the Dividend will be contingent
                  upon the consummation of the transactions contemplated by the
                  Share Exchange Agreement and the Company Stock Purchase
                  Agreement.

         (1)      "CHANGE IN BUSINESS": TACT and IOT advise that the
                  implementation of the Share Exchange Agreement, the Company
                  Stock Purchase Agreement and the Shareholder Stock Purchase
                  Agreement would constitute a material change in the nature of
                  business as conducted by TACT and/or IOT.

         (m)      ANTICIPATED FAILURE TO COMPLY WITH EBITDA COVENANT SET FORTH
                  IN SECTION 15.23 OF THE LOAN AGREEMENT: TACT and IOT advise
                  that they anticipate that they will fail to comply with the
                  EBITDA Covenant set forth in Section 15.23 of the Loan
                  Agreement as at the test date of March 31, 2005. TACT and IOT
                  request a waiver of any such failure to comply with the
                  aforesaid EBITDA Covenant set forth in Section 15.23 of the
                  Loan Agreement as at the test date of March 31, 2005.

         (n)      RELEASE OF SHMUEL BENTOV FROM VALIDITY/SUPPORT OBLIGATIONS:
                  Pursuant to the terms of a certain instrument of validity and
                  support dated as of March 23, 2004, and entitled "Validity and
                  Support Agreement", the Selling Shareholder Shmuel BenTov has
                  made certain representations and covenants and given certain
                  warranties relating to TACT, the Loan Agreement and the
                  Collateral as defined in and given to Keltic thereunder. In
                  light of his remaining with TACT solely in a business
                  development and advisory role after the consummation of the
                  transactions contemplated by the Share Exchange Agreement and
                  the Company Stock Purchase Agreement, Selling Shareholder
                  Shmuel BenTov has requested his release from his obligations
                  under the aforesaid "Validity and Support Agreement".

         (o)      Relevant Transaction Documents: All of the foregoing has been
                  implemented by the following documents:

                  (1)      Share Exchange Agreement, dated as of January 21,
                           2005, among Vanguard, the Vanguard Stockholders, the
                           authorized representative named therein and TACT.

                  (2)      Company Stock Purchase Agreement, dated as of January
                           21, 2005, by and between Oak and TACT.

                  (3)      Shareholder Stock Purchase Agreement, dated as of
                           January 21, 2005, between Oak and Selling Shareholder
                           Shmuel BenTov.

                           and between Oak and Selling Shareholder Shmuel
                           BenTov.

                  (5)      Employment Agreement, dated as of January 21, 2005,
                           between TACT and Richard D. Falcone.

                  (6)      Certificate of Amendment (to Articles of
                           Incorporation);



         TACT and IOT have asked for Keltic's approval of the foregoing.
Keltic's approval is required because each of the above described transactions
would otherwise violate various provisions of the Loan Agreement. This is so for
various reasons, including without limitation each of the following:

         Section 14.1 of the Loan Agreement provides as follows:



                  AFFIRMATIVE COVENANTS. Each Borrower represents and warrants
                  that, so long as it shall have any Obligations to Lender
                  hereunder, each such Borrower will:

                  14.1. BUSINESS AND EXISTENCE. Preserve and maintain each such
                  Borrower's separate corporate existence and rights, privileges
                  and franchises in connection herewith.

         The execution and implementation of the Share Exchange Agreement, the
Company Stock Purchase Agreement, the Shareholder Stock Purchase Agreement and
the Voting Agreement would

violate the aforesaid Section 14.1 of the Loan Agreement by materially and
directly changing TACT'S rights, privileges and franchises and by materially and
indirectly changing IOT's rights, privileges and franchises.

         Section 14.2 of the Loan Agreement provides as follows:

                  AFFIRMATIVE COVENANTS. Each Borrower represents and warrants
                  that, so long as it shall have any Obligations to Lender
                  hereunder, each such Borrower will:

                  14.2 TRADE NAMES. Transact business in each such Borrower's
                  own name and invoice all of each such Borrower's Receivables
                  in each such Borrower's own name.

         TACT'S change of its name from "The A Consulting Team, Inc." to
"Vanguard InfoSolutions International Inc." would violate the aforesaid Section
14.2 of the Loan Agreement.

         Section 15.2 of the Loan Agreement provides as follows:

                  NEGATIVE COVENANTS. So long as either Borrower shall have any
                  Obligations to Lender hereunder and unless Lender has first
                  consented thereto in writing, Borrowers shall not:

                  15.2 MERGERS; CONSOLIDATIONS; ACQUISITIONS. Enter into any
                  merger, consolidation, reorganization or recapitalization
                  after the date hereof with any other Person except for such
                  mergers, consolidations, reorganizations and recapitalizations
                  that (i) have been disclosed to and consented to by Lender in
                  writing, such consent not to be unreasonably withheld, and
                  (ii) do not have a Material Adverse Effect; ... acquire the
                  stock or assets of any Person, whether by merger,
                  consolidation, purchase of stock or otherwise except for
                  mergers, consolidations, purchases of stock or otherwise that
                  have been disclosed to and consented to by Lender; . . ..

         The execution and implementation of the Share Exchange Agreement, the
Company Stock Purchase Agreement, the Shareholder Stock Purchase Agreement and
the Voting Agreement would violate the above excerpted provisions of Section
15.2 of the Loan Agreement. In addition, the

conversion of TACT Series A Preferred Stock owned by Shmuel BenTov into TACT
Common Shares and the conversion of TACT Series B Preferred Stock owned by Yossi
Vardi into TACT Common Shares would also violate the above excerpted provisions
of Section 15.2 of the Loan Agreement.

         Section 15.6 of the Loan Agreement provides as follows:

                  NEGATIVE COVENANTS. So long as either Borrower shall have any
                  Obligations to Lender hereunder and unless Lender has first
                  consented thereto in writing, Borrowers shall not:

                  15.6. DIVIDENDS AND DISTRIBUTIONS. Pay any cash dividends
                  (provided, however, that payment of cash dividends on TACT's
                  Series A and Series B Preferred Stock is permitted so long as
                  no Event of Default has occurred and is continuing hereunder),
                  make any capital distribution in cash or other property or
                  return of capital ... or take any action which would have an
                  effect equivalent to any of the foregoing ....

         TACT's payment of dividends on the TACT Common Shares would violate the
aforesaid Section 15.6 of the Loan Agreement.

         Section 15.7 of the Loan Agreement provides as follows:

                  NEGATIVE COVENANTS. So long as either Borrower shall have any
                  Obligations to Lender hereunder and unless Lender has first
                  consented thereto in writing, Borrowers shall not:

                  15.7. BORROWERS' NAMES AND OFFICES. Transfer either Borrower's
                  chief executive office or change its company name or office
                  where it maintains records (including computer printouts and
                  programs) with respect to Receivables, except upon not less
                  than thirty (30) days advance written notice to Lender and
                  after the delivery to Lender of financing statements in form
                  and content satisfactory to Lender; provided, however, in no
                  event shall such Transfer be permitted if it shall render
                  unperfected or otherwise impair Lender's security interest in
                  the Collateral.

         TACT's change of its name from "The A Consulting Team, Inc." to
"Vanguard InfoSolutions International Inc." would violate the aforesaid Section
15.7 of the Loan Agreement.

         Section 15.16 of the Loan Agreement provides as follows:

                  NEGATIVE COVENANTS. So long as either Borrower shall have any
                  Obligations to Lender hereunder and unless Lender has first
                  consented thereto in writing, Borrowers shall not:

                  15.16. MODIFICATION OF GOVERNING DOCUMENTS. Make or permit any
                  change, alteration or modification of its Certificate of
                  Incorporation or By-laws which would result in a Material
                  Adverse Effect, or make any other change, alteration or
                  modification thereto except upon prompt written notice to
                  Lender.

         The execution and implementation of the Share Exchange Agreement, the
Company Stock Purchase Agreement, the Shareholder Stock Purchase Agreement and
the Voting Agreement and their effect on the management and control of TACT
would result in a Material Adverse Effect, thereby violating the aforesaid
Section 15.16 of the Loan Agreement. In addition, TACT's change of its name from
"The A Consulting Team, Inc." to "Vanguard Info-Solutions International Inc."
would also result in a Material Adverse Effect, thereby violating the aforesaid
Section 15.16 of the Loan Agreement.

         Section 15.17 of the Loan Agreement provides as follows:

                  NEGATIVE COVENANTS. So long as either Borrower shall have any
                  Obligations to Lender hereunder and unless Lender has first
                  consented thereto in writing, Borrowers shall not:

                  15.17. CHANGE OF BUSINESS. Cause or permit a material change
                  in the nature of its business as conducted on the date of this
                  Agreement.

         The execution and implementation of the Share Exchange Agreement, the
Company Stock Purchase Agreement and the Shareholder Stock Purchase Agreement
would constitute a material change in the nature of the business conducted by
TACT and/or IOT, thereby violating the aforesaid Section 15.17 of the Loan
Agreement.

         Section 19.1 (c) of the Loan Agreement provides as follows:

                  19.1 DEFAULTS. Upon the happening of any of the following
                  events (collectively, "Events of Default"):

                  other Loan Document or any other agreement between Lender and

                  excess of twenty (20) days after notice thereof is given by
                  Lender to Borrowers;

         The execution and implementation of the Share Exchange Agreement, the
Company Stock Purchase Agreement, the Shareholder Stock Purchase Agreement and
the Voting Agreement and their effect on the management and control of TACT
violates various terms, conditions, covenants and/or warranties of or in the
Loan Agreement, thereby violating the aforesaid Section 19.1 (c) of the Loan
Agreement. In addition, TACT's change of its name from "The A Consulting Team,
Inc." to "Vanguard Info-Solutions International Inc." violates various terms,
conditions, covenants and/or warranties of or in the Loan Agreement, thereby
violating the aforesaid Section 19.1 (c) of the Loan Agreement.

         Section 19.1(1) of the Loan Agreement provides as follows:



                  19.1 DEFAULTS. Upon the happening of any of the following
                  events (collectively, "Events of Default"):

                  Adverse Effect, which in the sole and absolute opinion of

violates various terms, conditions, covenants and/or warranties of or in the
