Item 5. Other Events.

     ENTEX Information Services, Inc. (the "Company") has entered into an
Agreement and Plan of Merger, dated as of March 13, 2000 (the "Merger
Agreement"), by and among the Company, Siemens Corporation, a Delaware
corporation ("Siemens"), and Emilia Acquisition Corp., a Delaware corporation
specifically organized for the purpose of effecting the Merger (as defined
below) and a direct, wholly owned subsidiary of Siemens ("Acquisition"),
pursuant to which the Company has agreed to consummate the merger (the "Merger")
of Acquisition with and into the Company. The Merger is subject to certain
conditions including the expiration or early termination of the waiting period
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended.

     Siemens, through Acquisition, will acquire in the Merger all of the
outstanding common stock of the Company (the "Common Stock") for an aggregate
cash purchase price of $105 million less the following deductions (the "Purchase
Price"), without duplication:

          (i) the amount by which the Company's current assets less total
     liabilities at the Measurement Date (as defined below) are less than the
     Company's current assets less total liabilities at September 26, 1999;

          (ii) the expenses of the Company in connection with the Merger,
     including legal and financial advisor fees and expenses and bonus,
     severance and additional compensation costs;

          (iii) the $12.5 million premium which will be payable in connection
     with the redemption of the Company's 12-1/2% Senior Subordinated Notes due
     2006 (the "Notes"), issued and outstanding pursuant to the Indenture dated
     July 29, 1998 (the "Notes Indenture") among the Company, the Subsidiary
     Guarantors (as defined therein) and Marine Midland, N.A., as trustee; and

          (iv) an amount equal to $32.2 million less the book value of the
     Company's 5.5% Convertible Subordinated Debentures due 2007, issued and
     outstanding pursuant to the Indenture dated March 18, 1987, as
     supplemented, between Businessland, Inc. and Security Pacific National
     Bank, as of the Measurement Date. It is estimated that this deduction will
     be approximately $12.0 million.

     The first $20.0 million (the "Indemnity Amount") of the Purchase Price will
be deposited into an interest-bearing escrow pursuant to an Escrow Agreement, to
be entered into on the Measurement Date (the "Escrow Agreement"), among the
Company, Siemens, ChaseMellon Shareholder Services, L.L.C., as the escrow agent,
and Dort A. Cameron III, the Chairman and controlling stockholder of the
Company, in his capacity as the stockholders' representative. The Indemnity
Amount shall be held and disbursed by the escrow agent to satisfy any
indemnification claims by Siemens relating to breaches of any representations,
warranties or covenants in the Merger Agreement. Any of these funds


<PAGE>
                                      -2-


not utilized for such purposes (net of escrow-related expenses) will be paid to
the former stockholders of the Company eighteen months following the Measurement
Date, except to the extent of any unresolved indemnification claims as of such
date.

     The next $20.0 million (the "Tax Escrow Amount") of the Purchase Price, if
any, will be deposited into an interest-bearing escrow pursuant to a Tax Escrow
Agreement, to be entered into on the Measurement Date (the "Tax Escrow
Agreement"), among the Company, Siemens, ChaseMellon Shareholder Services,
L.L.C., as the tax escrow agent, and Dort A. Cameron III, in his capacity as the
stockholders' representative. The funds deposited with the tax escrow agent
pursuant to the Tax Escrow Agreement are intended to provide Siemens with
indemnification for any tax liabilities and related expenses relating to the
Company's 1994, 1995 and 1996 fiscal years. Any of these funds not utilized for
such purposes (net of certain escrow-related expenses) will be paid to the
former stockholders of the Company upon receipt of a refund currently pending
before the IRS with respect to these tax years or other resolution of such tax
matters. While the timing of the refund or other definitive resolution of these
tax matters cannot be determined, it is not anticipated to occur prior to June
30, 2000.

     The remainder of the Purchase Price, if any (after a $500,000 reserve that
may be utilized by Dort A. Cameron III for expenses in his capacity as
stockholders' representative), will be released to the former stockholders of
the Company promptly following the later of the resolution of the Closing
Statement (as defined below) or the effective time of the Merger.

     Concurrently with the execution of the Merger Agreement, pursuant to a
Stockholders Agreement, dated as of March 13, 2000 (the "Stockholders
Agreement"), by and among Dort A. Cameron III, Entex Associates L.P., an
affiliates of Mr. Cameron, and John A. McKenna, Jr., the Chief Executive Officer
and a Director of the Company (collectively, the "Principal Stockholders"),
Siemens and Acquisition, the Principal Stockholders, among other things, granted
Acquisition an exclusive option (the "Call Option") to acquire 24,719,596 shares
of the Common Stock in the aggregate, exercisable at any time, at the Purchase
Price (payable at the same time(s) other stockholders of the Company receive
their consideration). In addition, the Principal Stockholders have received an
undertaking from Acquisition to purchase their shares, at their option (the "Put
Option"), for the Purchase Price in the event the Securities Exchange Commission
reviews the Company's Information Statement on Schedule 14C to be filed in
connection with the Merger and the conditions to the Merger are then satisfied.

     If either the Call Option or Put Option is exercised, the "Measurement
Date" will be the date shares of the Common Stock are purchased pursuant to such
exercise. If neither option is exercised, the "Measurement Date" will be the
effective time of the Merger, which will occur promptly upon satisfaction of the
conditions to the Merger. Holders of 7,104,148 shares of the Common Stock are
subject to drag-along obligations. If either the Call Option or the Put Option
is exercised, Mr. Cameron will exercise his drag-along rights, thereby requiring
the holders of such shares to sell such shares to Acquisition on the same terms
as his sale, including purchase price and timing of receipt of payment.


<PAGE>
                                      -3-


     Pursuant to the terms of the Merger Agreement, within thirty days following
the Measurement Date, Siemens will deliver to Mr. Cameron, in his capacity as
the stockholders' representative, a closing statement (the "Closing Statement")
setting forth the calculation of the Purchase Price, based on the balance sheet
of the Company as of the Measurement Date. Mr. Cameron will have up to 15 days
to either approve or object to their Closing Statement. If he objects to their
Closing Statement, there is a dispute resolution mechanism in the Merger
Agreement that contemplates resolution of any objections within 40 days after
Mr. Cameron's objections, although actual resolution may take longer.

     Each share of Common Stock will be entitled to receive its proportionate
share of the Purchase Price (as calculated in the manner and at the times
described above). As of March 9, 2000, there were 32,814,724 outstanding shares
of the Common Stock. Because the final deductions to the Purchase Price will not
be known until the Closing Statement is agreed to, and the total claims against
the escrow amounts will not be finally known until the end of the respective
escrow periods, the Company cannot determine at this time what either the
Purchase Price or the Purchase Price per share will be. However, the Company
estimates that the Purchase Price per share (including amounts that will be
subject to claims of Siemens under the Escrow Agreement and the Tax Escrow
Agreement) will be between $1.20 and $1.50, and may be significantly less than
such amount.

     In addition, pursuant to the terms of the Merger Agreement, and in
accordance with the terms of the Notes Indenture, the Company will call for
redemption all of the Notes outstanding at a redemption price equal to 112-1/2%
of their principal amount plus accrued interest to the date of redemption. The
redemption of the Notes will be funded by Siemens and is expected to take place
at least 30 days, and no more than 60 days, after the Measurement Date.

     The Merger Agreement, the Escrow Agreement, the Tax Escrow Agreement, the
Stockholders Agreement and the press release relating to the Merger are attached
as Exhibits 2.1, 10.1, 10.2, 10.3 and 99.1, respectively, and are incorporated
herein by reference into this Item 5 and the foregoing description of such
documents and transactions contemplated thereby are qualified in their entirety
by reference to such Exhibits.

                          AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of March 13,
2000, by and among SIEMENS CORPORATION, a Delaware corporation ("Siemens"),
EMILIA ACQUISITION CORP., a Delaware corporation ("Acquisition"), and ENTEX
INFORMATION SERVICES, INC., a Delaware corporation (the "Company"). Capitalized
terms used in this Agreement and not otherwise defined have the meanings
ascribed to them in Section 10.

                                    RECITALS

     A. The Company is a Delaware corporation, with its principal executive
office located at Six International Drive, Rye Brook, New York 10573.

     B. Siemens is a Delaware corporation with its principal offices located at
153 East 53rd Street, New York, New York 10022. Acquisition is a wholly owned
subsidiary of Siemens and was formed to merge with and into the Company so that,
as a result of the merger, the Company will survive and become a wholly owned
subsidiary of Siemens.

     C. The respective Boards of Directors of Siemens, Acquisition and the
Company have determined that this Agreement and the consummation of the merger
of Acquisition with and into the Company (the "Merger") in accordance with the
laws of the State of Delaware and subject to the terms and conditions of this
Agreement, is advisable and in the best interests of Siemens, Acquisition and
the Company, respectively, and their respective stockholders and have approved
this Agreement.

     D. The principal stockholder of the Company and certain of his affiliates
have simultaneously herewith entered into an agreement with Siemens and
Acquisition (the "Stockholders Agreement") in which those Persons have (i)
granted Acquisition an option to acquire their shares (the "Call Option"); (ii)
agreed to vote their shares (x) in favor of the adoption of this Agreement and
(y) against any Acquisition Transaction with any third party; (iii) agreed to
provide all notices and perform all actions necessary for the consummation of
the transactions contemplated herein; (iv) received an undertaking from
Acquisition to purchase their shares, at their option, under certain
circumstances (the "Put Option"); and (v) agreed to exercise certain rights (the
"Drag-Along Rights") to require various stockholders of the Company to sell
their shares on the same terms.

     E. The parties intend that Siemens' acquisition of the Company will be
accomplished in a single step pursuant to the Merger, but that under certain
conditions the acquisition will instead be accomplished in two phases - namely,
a purchase by Acquisition of the shares covered by the Stockholders Agreement,
followed by completion of the Merger. In this Agreement, the term "Initial
Purchase" refers to Acquisition's acquisition of the shares cov-


<PAGE>

ered by the Stockholders Agreement, either as a result of the exercise of the
Call Option or the Put Option, if that acquisition is prior to the Effective
Time, and the term "Initial Purchase Date" refers to the date on which title to
those shares passes to Acquisition.

     F. Certain officers and employees of the Company have executed and
delivered to Siemens employment agreements, termination and severance agreements
and/or non-competition/non-solicitation agreements that by their terms will take
effect as of the earlier of (i) the Effective Time or (ii) the Initial Purchase
Date.

     G. Siemens, Acquisition and the Company desire to make certain
representations and warranties, covenants and agreements in connection with the
Merger and/or the Initial Purchase and also to set forth the terms and
conditions of the Merger and the Initial Purchase, all as set forth in this
Agreement.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements contained herein and other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto intending to be legally bound do hereby agree
as follows:

     1. The Merger; Additional Actions.

     1.1 The Merger. At the Effective Time, upon the terms and subject to the
conditions of this Agreement, Acquisition shall be merged with and into the
Company in accordance with the provisions of the General Corporation Law of the
State of Delaware (the "DGCL"). The Company shall be the surviving corporation
in the Merger (the "Surviving Corporation"). As a result of the Merger, all of
the respective outstanding shares of capital stock of the Company and
Acquisition shall be converted or cancelled in the manner provided in Section 2.

     1.2 Effective Time. At the Closing, a certificate of merger (the
"Certificate of Merger") shall be duly prepared and executed by the Surviving
Corporation and thereafter delivered to the Secretary of State of the State of
Delaware (the "Secretary of State") for filing, as provided in Section 251 of
the DGCL, on, or as soon as practicable after, the Closing Date. The Merger
shall become effective at the time of the filing of the Certificate of Merger
with the Secretary of State, or at such later time as may be agreed by Siemens
and the Company and stated in the Certificate of Merger (the date and time of
such filing (or stated later time, if any) being referred to herein as the
"Effective Time").

     1.3 Closing. The closing of the Merger (the "Closing") shall take place at
the offices of Clifford Chance Rogers & Wells LLP, 200 Park Avenue,



                                      -2-
<PAGE>

New York, New York 10166, on a date and at a time to be specified by the
parties, which shall in no event be later than 10:00 a.m., local time, on the
second business day following satisfaction of the conditions set forth in
Section 6.1(e), (g) and (i), provided that the other closing conditions set
forth in Section 6 shall have been satisfied or, if permissible, waived in
accordance with this Agreement, or on such other date, time and place as the
parties may mutually agree (the "Closing Date"). At the Closing there shall be
delivered to Siemens, Acquisition and the Company the certificates and other
documents and instruments required to be delivered under Section 6.

     1.4 Effects of the Merger. At the Effective Time, the effects of the Merger
shall be as provided in the applicable provisions of the DGCL.

     1.5 Certificate of Incorporation, By-Laws and Officers and Directors of the
Surviving Corporation.

     (a) The certificate of incorporation of the Company, as in effect
immediately prior to the Effective Time, shall be amended in the Merger so as to
read in its entirety as set forth in Exhibit A and, as so amended, shall be the
certificate of incorporation of the Surviving Corporation until thereafter
amended as provided by law and such certificate of incorporation.

     (b) The by-laws in the form set forth in Exhibit B shall be the by-laws of
the Surviving Corporation until thereafter amended as provided by law, the
Certificate of Incorporation of the Surviving Corporation and such by-laws.

     (c) From and after the Effective Time, the directors and officers of the
Surviving Corporation shall be as set forth on Exhibit K hereto, until their
respective successors are duly elected and qualified or until their earlier
death, resignation or removal in accordance with the Surviving Corporation's
Certificate of Incorporation and By-Laws.

     1.6 Directors.

     If the Initial Purchase occurs:

     (a) Upon the Initial Purchase Date and from time to time thereafter so long
as Acquisition, Siemens and Siemens' other direct or indirect wholly-owned
Subsidiaries collectively continue to hold shares of Company Common Stock in an
amount at least equal to a majority of the outstanding voting power of the
Company's capital stock, Siemens shall be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of the
Company, each Subsidiary and each standing committee thereof as is equal to



                                      -3-
<PAGE>

the product of the total number of directors on the Board of Directors of the
Company, such Subsidiary and such committee (determined after giving effect to
the directors elected pursuant to this sentence), as the case may be, multiplied
by the percentage that the aggregate number of shares of Company Common Stock
beneficially owned by Siemens or its wholly owned Subsidiaries bears to the
total number of shares of Company Common Stock then outstanding, and the Company
shall, upon request of Siemens, promptly take all actions necessary to cause
Siemens' designees to be so elected, including, if necessary, increasing the
size of the Board of Directors of the Company or such Subsidiary or using its
best efforts to obtain the resignations of one or more existing directors of the
Company or such Subsidiary; provided, however, that prior to the Effective Time,
the Board of Directors of the Company and each Subsidiary shall contain at least
two members who are neither officers, directors nor designees of Siemens (the
"Company Designees").

     (b) The Company's obligations to appoint Siemens' designees to the Board
shall be subject to Section 14(f) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and Rule 14f-1 promulgated thereunder. The Company
shall promptly take all actions required pursuant to Section 14(f) and Rule
14f-1 in order to fulfill its obligations under this Section 1.6 and shall
distribute to its stockholders promptly following the execution and delivery of
this Agreement such written material as is required under such Section and Rule
in order to fulfill its obligations under this Section 1.6 (the "14(f)
Material"). Siemens will supply any information with respect to itself and its
officers, directors and Affiliates required by such Section and Rule to the
Company to be included in the 14(f) Material distributed by the Company.

     (c) From and after the election or appointment of Siemens' designees
pursuant to this Section 1.6, if any, and prior to the Effective Time, any
amendment or termination of this Agreement by the Company, any extension by the
Company of the time for the performance of any of the obligations or other acts
of Siemens or Acquisition or waiver of any of the Company's rights hereunder, or
any other action taken by the Board of Directors of the Company in connection
with this Agreement, will require the concurrence of a majority of the directors
of the Company then in office who are Company Designees.

     1.7 Further Assurances. Each party hereto shall execute such further
documents and instruments and take such further actions as may reasonably be
requested by one or more of the others to consummate the Merger, to vest the
Surviving Corporation with full title to all assets, properties, rights,
approvals, immunities and franchises of Acquisition and the Company or to
otherwise effect the purposes of this Agreement.

     2. Conversion of Shares.

     2.1 Conversion of Capital Stock. At the Effective Time, by virtue of the
Merger and without any further action on the part of any holder of capital stock
of the Company:

     (a) Capital Stock of Acquisition. Each issued and outstanding share of the
common stock, par value $.0001 per share, of Acquisition ("Acquisition Common
Stock") shall be converted into and become one fully paid and nonassessable
share of common stock, par value $.0001 per share, of the Surviving Corporation
("Surviving Corporation Common Stock"). Each certificate representing
outstanding shares of Acquisition Common Stock shall at the Effective Time
represent an equal number of shares of Surviving Corporation Common Stock.

     (b) Cancellation of Treasury Stock and Stock Owned by Siemens and
Acquisition. All shares of capital stock of the Company that are owned by the
Company as treasury stock and any shares of Company Common Stock owned by
Siemens or Acquisition or by any direct or indirect wholly-owned Subsidiary of
Siemens or Acquisition automatically shall be cancelled and shall cease to exist
and no consideration shall be delivered in exchange therefor.

     (c) Conversion of Company Capital Stock.

          (i) Each issued and outstanding share of the common stock, par value
     $.0001 per share, of the Company ("Company Common Stock") (other than
     shares to be cancelled in accordance with Section 2.1(b) and other than
     shares that are Dissenting Shares (as defined in Section 2.1(d)(i)) shall
     be converted into the right to receive an amount per share in cash (the
     "Merger Price") equal to the quotient of (x) the Adjusted Acquisition Price
     divided by (y) the number of shares of Company Common Stock that are issued
     and outstanding immediately prior to the Effective Time (the "Outstanding
     Share Amount"); provided, however, that in no event shall the aggregate
     Merger Price exceed the sum of (i) 66,942,037 plus (ii) the aggregate
     amount in cash received by the Company after the date of this Agreement and
     prior to the Effective Time upon exercise of Options.

     All such shares of Company Common Stock shall no longer be outstanding and
shall be cancelled automatically and shall cease to exist, and each holder of a
certificate representing any such shares of Company Common Stock shall cease to
have any rights with respect thereto, except the right to receive, subject to
the terms of the Escrow Agreement and the Tax Escrow Agreement and Sections
2.1(c)(ii), (iii) and (iv), the Merger Price and, if applicable, the Incremental
Amount per share, upon the surrender of such certificate in accordance with
Section 2.3, without interest. For purposes of this Agreement, the term
"Adjusted Acquisition



                                      -5-
<PAGE>

Price" shall be (i) $105,000,000 (the "Acquisition Price") minus (ii) the
Closing Liquid Net Worth Adjustment plus (iii) an additional amount equal to the
product of (x) the amount determined pursuant to the preceding clauses (i) and
(ii) times (y) 6.5% per year from the Measurement Date to the Effective Time,
calculated on an uncompounded basis.

          (ii) The first $20,000,000 of the aggregate Merger Price and, if
     applicable, Incremental Amount (the "Indemnity Amount") shall be deposited
     into escrow pursuant to the terms of the Escrow Agreement. In accordance
     with the terms of the Escrow Agreement, following completion of the Escrow
     period, the Remaining Escrow Balance shall be deposited with the Payment
     Agent in accordance with Section 2.3 for distribution to the holders of
     shares of the Company Common Stock as of the Effective Time in proportion
     to their respective share ownership.

          (iii) If the Tax Insurance Election is made, to the extent the
     aggregate Merger Price and, if applicable, Incremental Amount exceeds
     $20,000,000, the next $20,000,000 of the aggregate Merger Price and, if
     applicable, Incremental Amount (the "Tax Escrow Amount") shall be deposited
     into escrow pursuant to the terms of the Tax Escrow Agreement. In
     accordance with the terms of the Tax Escrow Agreement, following completion
     of the Tax Matters Escrow Period, the Tax Escrow Balance shall be deposited
     with the Payment Agent in accordance with Section 2.3 for distribution to
     the holders of shares of Company Common Stock as of the Effective Time in
     proportion to their respective share ownership.

          (iv) To the extent the aggregate Merger Price and, if applicable,
     Incremental Amount exceeds $20,000,000 or, if the Tax Insurance Election is
     made, $40,000,000, the next $500,000 of the aggregate Merger Price and, if
     applicable, Incremental Amount (the "Stockholder Representative Expense
     Amount") shall be paid to the Stockholders' Representative for the purpose
     of funding expenses in connection with his performance of the duties of
     Stockholders' Representative; provided that the Stockholders'
     Representative shall deliver an undertaking to the Company pursuant to
     which he will agree to deliver to the Payment Agent any portion of such
     amount not utilized for such purpose, which portion shall be distributed to
     the holders of shares of Company Common Stock as of the Effective Time in
     proportion to the respective share ownership.

          (v) If the Effective Time occurs prior to the date letters of
     transmittal are first mailed pursuant to Section 2.4(b), an additional
     amount per share of Company Common Stock shall be received upon conversion
     of each share in the Merger in an amount equal to product of (x) the Merger
     Price and (y) 6.5% per year from the Effective Time until the date letters
     of transmittal are first mailed pursuant to Section 2.4(b), calculated on
     an uncompounded basis (the "Incremental Amount").



                                      -6-
<PAGE>

     (d) Dissenting Shares. Notwithstanding any provision of this Agreement to
the contrary, each outstanding share of Company Common Stock the holder of which
has not voted in favor of the Merger, has perfected such holder's right to an
appraisal of such holder's shares in accordance with the applicable provisions
of the DGCL and has not effectively withdrawn or lost such right to appraisal
(in each case a "Dissenting Share"), shall not be converted into or represent a
right to receive the Merger Price and, if applicable, the Incremental Amount
pursuant to Section 2.1(c), but rather the holder thereof shall be entitled only
to such rights as are granted by the applicable provisions of the DGCL;
provided, however, that any Dissenting Share held by a Person at the Effective
Time who shall, after the Effective Time, withdraw the demand for appraisal or
lose the right of appraisal, in either case pursuant to the DGCL, shall be
deemed to be converted into, as of the Effective Time, the right to receive,
subject to the terms of the Escrow Agreement and the Tax Escrow Agreement and
Sections 2.1(c)(ii), (iii) and (iv), the Merger Price and, if applicable, the
Incremental Amount pursuant to Section 2.1(c).

     The Company shall give Siemens (x) prompt notice of any written demands for
appraisal, withdrawals of demands for appraisal and any other instruments served
pursuant to the applicable provisions of the DGCL relating to the appraisal
process received by the Company and (y) the exclusive right to direct all
negotiations and proceedings with respect to demands for appraisal under the
DGCL. The Company will not, except with the prior written consent of Siemens,
voluntarily make any payment with respect to any demands for appraisal or settle
or offer to settle any such demands.

     (e) Treatment of Options. As of the date of this Agreement, each option to
purchase Company Common Stock that is then outstanding (each an "Option")
pursuant to a compensation plan or arrangement of the Company (the "Company
Stock Plans"), whether or not then vested or exercisable, will become vested and
exercisable. Each Option (other than Options issued pursuant to the Company's
1996 Performance Incentive Plan) that has not been exercised as of the Effective
Time shall be cancelled without consideration. Each Option issued pursuant to
the Company's 1996 Performance Incentive Plan that has not been exercised as of
the Effective Time shall be exercisable solely for cash in an amount not to
exceed the Merger Price. Prior to the Effective Time, the Company will obtain
all consents and make all amendments, if any, to the terms of Options and the
Company Stock Plans, if any, pursuant to which the Options were issued that are
necessary to give effect to the provisions of this Section 2.1(e).

     (f) Warrants. At the Effective Time, each warrant to purchase Company
Common Stock that is outstanding as of the Effective Time (each a "Warrant")
pursuant to any of the Warrant Agreements or otherwise shall be exercisable
solely for cash in an amount not to exceed the Merger Price. Prior to the
Effective Time, the Company will obtain all consents and



                                      -7-
<PAGE>

make all amendments, if any, to the terms of the Warrants and the Warrant
Agreements that are necessary to give effect to the provisions of this Section
2.1(f).

     2.2 Closing Statement Procedures.

     (a) As promptly as practicable, but in any event not later than 30 days
after the date (the "Measurement Date") that is the first to occur of (i) the
Closing Date and (ii) the Initial Purchase Date, Siemens shall cause to be
prepared and delivered to Dort A. Cameron, III (the "Stockholders'
Representative") a draft Closing Statement substantially in the form of Exhibit
C setting forth (x) the balance sheet of the Company at the close of business on
the Measurement Date, which shall be prepared using the procedures and
methodologies set forth in Exhibit C, and (y) Siemens' calculation (based on the
amounts set forth on the balance sheet) of the Closing Liquid Net Worth
Adjustment.

     (b) Subject to the provisions of paragraph (c) below, the Stockholders'
Representative shall have 15 days from the date of delivery of the Closing
Statement to review and approve the Closing Statement. If the Stockholders'
Representative agrees with Siemens' calculation of the Closing Liquid Net Worth
Adjustment contained in the Closing Statement, the Stockholders' Representative
shall promptly so advise Siemens in writing, in which event the Closing Liquid
Net Worth Adjustment shall be deemed final and the Adjusted Acquisition Price
shall be calculated and deposited with the Payment Agent in accordance with
Section 2.3.

     (c) If the Stockholders' Representative in good faith disagrees with the
calculation of the Closing Liquid Net Worth Adjustment set forth in the Closing
Statement, the Stockholders' Representative shall notify Siemens in writing (the
"Notice of Disagreement") of such disagreement within 15 days after delivery of
the Closing Statement. The Notice of Disagreement shall set forth in reasonable
detail the basis for the disagreement. Thereafter, Siemens and the Stockholders'
Representative shall attempt in good faith to resolve and finally determine the
Closing Liquid Net Worth Adjustment. If Siemens and the Stockholders'
Representative are unable to resolve the disagreement within 10 days after the
delivery of the Notice of Disagreement, Siemens and the Stockholders'
Representative shall appoint PriceWaterhouse Coopers (the "Independent
Accountant") to resolve the disputed items and make a determination with respect
thereto. Such determination will be made, and written notice thereof given to
Siemens and the Stockholders' Representative, within 30 days after such
selection. The determination by the Independent Accountant shall be final,
binding and conclusive upon the parties hereto. The scope of the Independent
Accountant's engagement (which shall not be an audit) shall be limited to the
resolution of the items contained in the Notice of Disagreement, and the
recalculation, if any, of the Closing Liquid Net Worth Adjustment in light of
such resolution and such firm shall be deemed to be acting as experts and not as
arbitrators. In their review of the Closing Statement and recalculation of the
Closing Liquid Net Worth



                                      -8-
<PAGE>

Adjustment, the Independent Accountant will be limited to using the procedures
and methodologies set forth in Exhibit C. The fees, costs and expenses of the
Independent Accountant, if any, will be borne equally by Siemens and the
Stockholders' Representative (it being understood that the Stockholders'
Representative's portion thereof shall be one of the expenses for which he is
entitled to receive reimbursement in accordance with the terms of the Escrow
Agreement). Within five days of delivery of a notice of determination by the
Independent Accountant as described above, the applicable portions of the
Adjusted Acquisition Price (calculated using the Closing Liquid Net Worth
Adjustment so determined by the Independent Accountant) shall be delivered or
made available to the Payment Agent, the Escrow Agent, the Stockholders'
Representative and/or the Tax Escrow Agent, as the case may be, in accordance
with Section 2.3.

     2.3 Deposits of Funds at and following the Closing.

     (a) On the date (the "Initial Distribution Date") which is the later to
occur of (i) the date on which the Adjusted Acquisition Price is determined
pursuant to the provisions of Section 2.2 or (ii) the Effective Time, (x)
Siemens shall deposit with the Escrow Agent funds in an amount equal to the
Indemnity Amount, (y) if the Tax Insurance Election is not made, Siemens shall
deposit with the Stockholders' Representative, the Stockholders' Representative
Expense Amount, if any, and shall deposit with the Payment Agent the balance, if
any, of the aggregate Merger Price and the aggregate Incremental Amount, if any,
and (z) if the Tax Insurance Election is made, Siemens: shall deposit with the
Tax Escrow Agent the Tax Escrow Amount, if any; shall deposit with the
Stockholders' Representative, the Stockholders' Representative Expense Amount,
if any; and shall deposit with the Payment Agent the balance, if any, of the
aggregate Merger Price and the aggregate Incremental Amount, if any.

     2.4 Payment for Certificates.

     (a) Exchange Fund. Siemens shall appoint the Payment Agent no later than
the Closing Date. The Payment Agent shall agree to hold the funds deposited with
it pursuant to Section 2.3 and, in its capacity as the Escrow Agent pursuant to
the Escrow Agreement and as the Tax Escrow Agent pursuant to the Tax Escrow
Agreement (such funds, together with earnings thereon, being referred to herein
as the "Exchange Fund"), for disbursement as provided in this Section 2.4.

     (b) Payment Procedures. As soon as reasonably practicable (and in any event
not later than five business days) after the Initial Distribution Date, the
Surviving Corporation shall cause to be mailed to each holder of record of a
certificate or certificates which immediately prior to the Effective Time
represented outstanding shares of Company Common Stock (the "Certificates")
whose shares are converted pursuant to Section 2.1(c) into the right to receive


                                      -9-
<PAGE>

the merger consideration described in Section 2.1(c), (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Payment Agent and shall be in such form and have such other
provisions as the Surviving Corporation may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the portions, if any, of the Merger Price and Incremental Amount, if any,
deposited with the Payment Agent on the Initial Distribution Date. Upon
surrender of a Certificate to the Payment Agent, together with such letter of
transmittal, duly executed and completed in accordance with its terms, the
holder of such Certificate shall be entitled to receive in exchange therefor a
check representing such portion, if any, of the Merger Price and Incremental
Amount, if any, per share of Company Common Stock represented thereby which such
holder has the right to receive pursuant to the provisions of Section 2.1(c),
and the Certificate so surrendered shall forthwith be cancelled. Except as
otherwise provided in this Agreement, the Tax Escrow Agreement or the Escrow
Agreement, in no event shall the holder of any Certificate be entitled to
receive interest on any funds to be received in the Merger. Until surrendered as
contemplated by this Section 2.4(b), each Certificate shall be deemed at all
times after the Effective Time to represent only the right to receive the merger
consideration provided for in this Agreement.

     (c) Tax Escrow Balance. As soon as reasonably practicable (and in any event
not later than five business days) following the end of the Tax Matters Escrow
Period, Siemens shall cause to be mailed to each Person entitled to a portion of
the Tax Escrow Balance pursuant to Section 2.1(c) a notice setting forth (i) the
amount of the Tax Escrow Balance and (ii) instructions for obtaining the amount
thereof to which each such Person is entitled pursuant to Section 2.1(c) from
the Payment Agent. Upon compliance by each such Person with those instructions,
such Person shall be entitled to be paid the applicable amount due under Section
2.1(c). Except as expressly provided in the Tax Escrow Agreement, in no event
shall interest be paid on any such amount.

     (d) Remaining Escrow Balance. As soon as reasonably practicable (and in any
event not later than five business days) following the end of the Escrow Period,
Siemens shall cause to be mailed to each Person entitled to a portion of the
Remaining Escrow Balance pursuant to Section 2.1(c) a notice setting forth (i)
the amount of the Remaining Escrow Balance and (ii) instructions for obtaining
the amount thereof to which each such Person is entitled pursuant to Section
2.1(c) from the Payment Agent. Upon compliance by each such Person with those
instructions, such Person shall be entitled to be paid the applicable amount due
under Section 2.1(c). Except as expressly provided in the Escrow Agreement, in
no event shall interest be paid on any such amount.



                                      -10-
<PAGE>

     (e) No Further Ownership Rights in Company Common Stock. From and after the

being conducted and to own, use and lease its assets and properties. Each
Subsidiary is duly qualified or licensed as a foreign corporation to do business
and is in good standing in each jurisdiction specified in Section 3.5 of the
Disclosure Schedule, which are the only jurisdictions in which nature of its

outstanding capital stock and the record owners of such outstanding capital
stock. All of the outstanding shares of capital stock of each Subsidiary have

capital stock of any Subsidiary. The name of each director and officer of each
Subsidiary on the date hereof, and the position with such Subsidiary held by

Adverse Effect, the Company and all Plans are in compliance with applicable
provisions of ERISA and, with respect to the Plans, the Code.

     (b) Except as would not have a Material Adverse Effect, all Pension Plans
that are intended to be qualified under Section 401(a) of the Code have been the
subject of determination, opinion, notification or advisory letters from the IRS
to the effect that such Pension Plans are so qualified and are exempt from
Federal income taxes under Section 501(a) of the Code, and no such determination
letter has been revoked nor has any event occurred since the date of such Plan's
most recent determination letter that would reasonably be expected to adversely
affect its qualification.

     (c) Neither the Company nor any Commonly Controlled Entity has within the
previous five years, maintained, contributed to or been obligated to contribute
to any Plan that is subject to Title IV of ERISA including, without limitation
any multi-employer plan (as defined in Section 3 (37) of ERISA).

nor any Subsidiary has any liability or obligation under any Welfare Plan to
provide life insurance or medical or health benefits after termination of
employment to any employee or dependent other than as required by Part 6 of

or any proceeding or other claim, action (other than claims for benefits in the
normal operations of the Benefit Plans), suit or proceeding against or involving
any Benefit Plan or asserting any right or claim to benefits which is likely to
be adversely determined and which, if so determined, would reasonably be
expected to have a Material Adverse Effect.

     (h) All contributions, premiums and other payments required by law or any
Plan or applicable collective bargaining agreement to have been made under any
such Plan or agreement to any fund, trust or account established thereunder or
in connection therewith have been made by the due date thereof.

     (i) Without limiting any other provision of this Section 3.18, except as
would not have a Material Adverse Effect, no event has occurred and no condition
exists, with respect to any Plan (whether or not maintained by the Company or
the Surviving Corporation), that has subjected or could subject the Company, any
Subsidiary, the Surviving Corporation or Siemens, or any Plan or any successor
thereto, to any material tax, fine, penalty or other liability (other than, in
the case of the Company, the Subsidiaries and the Plans, a liability arising in
the normal course to make contributions or payments, as applicable, when
ordinarily due under a Plan with respect to employees or former employees of the
Company or any Subsidiary). Except as would not have a Material Adverse Effect,
no event has occurred and no condition exists, with respect to any Plan that
could subject Siemens or any of its Affiliates, or any plan maintained by
Siemens or any Affiliate thereof, to any material tax, fine, penalty or other
liability, that would not have been incurred by Siemens or any of its
Affiliates, or any such Plan, but for the transactions contemplated hereby. No
employee benefit plan other than a Plan is or will be directly or indirectly
binding on the Surviving Corporation solely by virtue of the transactions
contemplated hereby. Siemens, and its Affiliates, including on and after the
Closing, the Surviving Corporation, shall have no material liability for, under,
with respect to or otherwise in connection with any employee plan, which
liability arises under ERISA or the Code, by virtue of the Company or any
Subsidiary being aggregated in a controlled group



                                      -27-
<PAGE>

or affiliated service group with any Commonly Controlled Entity for purposes of
ERISA or the Code at any relevant time prior to the Closing. Each Plan may be

Subsidiaries.

employee, investment banker, financial advisor, attorney, accountant or other
agent or representative (each, a "Representative") retained by or acting for or
on behalf of the Company or any of its Subsidiaries to, directly or indirectly,
initiate, solicit, encourage, or, unless the Board of Directors of the Company
believes, after consultation with outside legal counsel, that the failure to
take such actions would constitute a breach of the fiduciary duties of the Board
of Directors, participate in any negotiations regarding, furnish any
confidential information in connection with, endorse or otherwise cooperate
with, assist, participate in or facilitate the making of any proposal or offer
for, or which may reasonably be expected to lead to, an Acquisition Transaction,
by any Person, or group (a "Potential Acquiror"); provided, however, that (i)
the Company may furnish or cause to be furnished information concerning the
Company and its businesses, properties or assets to a Potential Acquiror, (ii)
the Company may engage in discussions or negotiations with a Potential Acquiror,
(iii) following receipt of a proposal or offer for an Acquisition Transaction,
the Company may make disclosure to the Company's stockholders and may recommend
such proposal or offer to the Company's stockholders and (iv) following receipt
of a proposal or offer for an Acquisition Transaction, the Board of Directors
may enter into an agreement in principle or a definitive agreement with respect
to such Acquisition Transaction, but in each case referred to in the foregoing
clauses (i) through (iv) only to the extent that the Board of Directors of the
Company shall have first concluded in good faith after consultation with outside
legal counsel that such action is necessary or appropriate because failure to
take such action would constitute a breach of the fiduciary duties owed by the
Board of Directors of the Company to the Company's stockholders under applicable
law; and provided, further, that the Board of Directors of the Company shall not
take or permit the Company to take any of the foregoing actions referred to in
clauses (i) through (iv) without prior written notice to Siemens with respect to
such action. The Company shall promptly inform Siemens, orally and in writing,
of the material terms and conditions of any proposal or offer for, or which may
reasonably be expected to lead to, an Acquisition Transaction that it receives
and the identity of the Potential Acquiror. The Company will immediately cease
and cause to be terminated any existing activities, discussions or negotiations
with any parties conducted on or prior to the date of this Agreement heretofore
with respect to any Acquisition Transaction. As used in this Agreement,
"Acquisition Transaction" means any merger, consolidation or other business
combination involving the Company, or any acquisition in any manner of all or a
substantial portion of the equity of, or all or a substantial portion of the
assets of, the Company, whether for cash, securities or any other consideration
or combination thereof, other than pursuant to the transactions contemplated by
this Agreement.

transactions contemplated hereby of governmental or regulatory authorities);
provided that to the extent reasonably practicable Siemens shall provide the
Company with reasonable notice of such compelled disclosure, or (ii) disclosed

condition. 5.10 Cooperation. (a) The Company hereby acknowledges and agrees
that, in the event Siemens or any of its Affiliates undertakes to redeem,
repurchase or repay all or any portion of the outstanding Notes, Debentures

     5.11 Director and Officer Indemnification.

     (a) Siemens agrees that all rights to indemnification now existing in favor
of any current or former director or officer of the Company as provided in the
Company's Certificate of Incorporation or by-laws or in a written agreement
between any such person and the Company in effect on the date hereof shall
survive the Merger and shall continue in full force and effect until the
expiration of all applicable statutes of limitation. Siemens also agrees to
indemnify all current and former directors and officers of the Company to the
fullest extent the Company would be permitted by the DGCL to indemnify them with

officers or directors of the Company or any of the Subsidiaries or as trustees
or fiduciaries of any plan for the benefit of employees occurring prior to the
Effective Time. Without limitation of the foregoing, in the event any such
person is or becomes involved in any capacity in any action, proceeding or
investigation in connection with any matter, including, without limitation, the
transactions contemplated by this Agreement, occurring prior to, and including,

action or proceeding or separate but substantially similar actions or
proceedings arising out of the same general allegations, be liable for
reasonable fees and expenses of more than one separate firm of attorneys (in
addition to any local counsel) at any time for all indemnified persons. Siemens
shall be entitled to participate in the defense of any such action or
proceeding, and counsel selected by the indemnified person shall, to the extent
consistent with their professional responsibilities, cooperate with Siemens and
any counsel designated by Siemens. Siemens shall pay all reasonable expenses,
including attorneys' fees, that may be incurred by any indemnified person in
enforcing the indemnity and other obligations provided for in this Section 5.11.

     (b) Siemens agrees that the Company and, from and after the Effective Time,
the Surviving Corporation shall cause to be maintained in effect for not less
than six years from the Effective Time the current policies of directors' and
officers' liability insurance maintained by the Company; provided that the
Surviving Corporation may substitute therefor policies of at least the same
coverage containing terms and conditions which are no less advantageous to such
persons; and provided, further, that such substitution shall not result in any
gaps or lapses in coverage with respect to matters occurring prior to the
Effective Time; and provided, further, that the Surviving Corporation shall not
be required to pay an annual premium in excess



                                      -41-
<PAGE>

of 200% of the last annual premium paid by the Company prior to the date hereof;

     7. Survival; Indemnification; Tax Matters.

     7.1 Survival. Except as otherwise provided herein, all the representations,
warranties covenants and agreements of the Company contained in or made pursuant
to this Agreement shall survive the Closing and shall remain operative and in
full force and effect for a period of 18 months after the Measurement Date (such
period being referred to as the "Escrow Indemnity Period"), regardless of any
investigation or statement as to the results thereof made by or on behalf of any
Person before or after the Closing. No claim for indemnification may be asserted
after the expiration of the Escrow Indemnity Period. Notwithstanding anything
herein to the contrary, any representation, warranty, covenant and agreement
which is the subject of a claim which is asserted in writing prior to the
expiration of the Escrow Indemnity Period shall survive with respect to such
claim or any dispute with respect thereto until the final resolution thereof.

     7.2 Indemnification. Siemens, its employees, agents, directors, officers,
subsidiaries and its affiliates and the employees, agents, directors, officers
and subsidiaries of its affiliates (the "Indemnified Parties") shall be
indemnified and held harmless from and against any and all damages, claims,
losses (including loss of value), expenses, costs, obligations and liabilities,
including without limitation liabilities for all reasonable attorneys',
accountants', and experts' fees and expenses including those incurred to enforce
the terms of this Agreement or any Collateral Document (collectively, "Losses")
(provided, however, that to avoid double-counting, Losses shall be determined
after giving effect to any reserves or liabilities reflected on the final
Closing Statement, if and to the extent those reserves reduced the Closing
Liquid Net Worth), asserted against, or paid, suffered or incurred by any
Indemnified Party which, directly or indirectly, arise out of, result from, are
based upon or relate to: (i) the inaccuracy, untruth or incompleteness, as of
the date of this Agreement or the Measurement Date (or, in the case of
representations and warranties made as of a specified date earlier than the
Measurement Date, on and as of such earlier date), of any representation or
warranty made or deemed to have been made by the Company in this Agreement or
any failure by the Company to perform or fulfill any of its covenants or
agreements set forth in this Agreement; provided, however that if any such
representation or warranty (other than those representations and warranties
contained in Section 3.7, Section 3.9(a) and Section 3.24) is qualified in any
respect by materiality or Material Adverse Effect, for purposes of this
paragraph such materiality or Material Adverse Effect qualification will be in
all respects ignored; (ii) subject to Section 7.9(b), Pre-Measurement Date Tax
Liabilities; (iii) the Asset Purchase Agreement, dated as of May 10, 1999, by
and between CompuCom Systems, Inc. and the Company or any of the transactions
contemplated thereby; (iv) any action, suit or proceeding commenced prior to the
Measurement Date before any court or arbitral or



                                      -45-
<PAGE>

other tribunal; (v) the Tax Matters Settlement Shortfall Amount; or (vi) any
failure of the Company or any of its Subsidiaries to be Year 2000 Compliant.

     7.3 Limitation of Liability; Disposition of Escrow Fund. After the Closing,
the Indemnified Parties' rights to indemnification under Section 7.2 shall be
subject to the following limitations: (i) in no event shall the aggregate amount
to be paid to the Indemnified Parties under Section 7.2 exceed the Indemnity
Amount; (ii) the Indemnified Parties shall be entitled to recover any Loss
otherwise recoverable pursuant to clauses (i), (iii), (iv) and (vi) of Section
7.2 only to the extent the aggregate of Losses otherwise recoverable pursuant
such Section exceeds $1,000,000 in the aggregate; provided, that if all such
Losses exceed $1,000,000, the Indemnified Parties shall be entitled to recover
for all such Losses; and (iii) if the inaccuracy, untruth or incompleteness of a
representation in Section 3.17 results in an increase in the taxable income of
the Company or any Subsidiary with respect to any taxable period ending after
the Measurement Date, such increase in taxable income shall not give rise to an
indemnifiable Loss to the extent such increase in taxable income is properly
offset by available net operating loss carryovers of the Company or any
Subsidiary (as the case may be) from taxable periods beginning prior to the
Measurement Date.

     7.4 Stockholders' Representative. (a) The Company hereby appoints, and the
Company's stockholders shall be deemed to appoint, the Stockholders'
Representative, with full and unqualified power to delegate to one or more
Persons the authority granted to him hereunder, to act as each of their agent
and attorney-in-fact, with full power of substitution, to take all actions
called for by this Section 7 and the Escrow Agreement and, if applicable, the
Tax Escrow Agreement, on their individual and collective behalf, in accordance
with the terms of this Section 7 and the Escrow Agreement and, if applicable,
the Tax Escrow Agreement.

     (b) The Stockholders' Representative shall have no liability whatsoever to
any existing or former stockholder of the Company or to any other Person arising
out of the matters contemplated by this Section 7 or the Escrow Agreement or, if
applicable, the Tax Escrow Agreement, except only to the extent of any Loss
caused exclusively by the Stockholders' Representative's willful misconduct or
bad faith. In any event, any such liability shall be limited to direct damages
resulting from such conduct and in no event shall the Stockholders'
Representative be liable for special, incidental or consequential damages
incurred or suffered by any Person. The Stockholders' Representative shall incur
no liability to any existing or former stockholder of the Company or to any
other Person with respect to any action taken or suffered by him in reliance
upon any note, direction, instruction, consent, statement or other documents
believed by him to be genuine and duly authorized. The Stockholders'
Representative may, in all questions arising under the Escrow Agreement and, if
applicable, the Tax



                                      -46-
<PAGE>

Escrow Agreement, rely on the advice of counsel and for anything done, omitted
or suffered in good faith by the Stockholders' Representative based on such
advice, the Stockholders' Representative shall not be liable to any existing or
former stockholder of the Company or to any other Person.

     (c) In the event of the death or permanent disability of the Stockholders'
Representative, or his resignation, a successor Stockholders' Representative
shall be appointed by a majority vote of the holders (other than Siemens and its
subsidiaries) of outstanding capital stock of the Company immediately prior to
the Effective Time, with each such stockholder (or his or her successors or
assigns) to be given a vote equal to the number of votes represented by the
shares of capital stock of the Company held by such stockholder immediately
prior to the Effective Time.

     7.5 Notice of Claims. If any of the Indemnified Parties believes that it
has suffered or incurred any Loss, it shall notify the Escrow Agent and the
Stockholders' Representative promptly in writing (at their respective addresses
set forth in the Escrow Agreement), and in any event within the applicable time
period specified in Section 7.1, describing such Loss, all with reasonable
particularity and containing a reference to the provisions of this Agreement in
respect of which such Loss shall have occurred (a "Claim Notice"). If any legal
action is instituted by a third party with respect to which any of the
Indemnified Parties intend to claim indemnity under this Section, such
Indemnified Party shall promptly give a Claim Notice to notify the Escrow Agent
and the Stockholders' Representative with respect to such legal action. In any
event, a failure or delay in notifying the Escrow Agent and the Stockholders'
Representative shall not affect the Indemnified Party's right to indemnity,
except only to the extent such failure or delay materially and adversely
prejudices the ability to defend against any legal action.

     7.6 Defense of Third Party Claims. Because the right to indemnity is
limited as provided herein, except as otherwise provided in the Tax Escrow
Agreement relating solely to the Tax Matters (as defined in the Tax Matters
Escrow Agreement), the Indemnified Parties shall have the right to conduct and
control, through counsel of their own choosing, reasonably acceptable to the
Stockholders' Representative, any third party legal action or other claim, but
the Stockholders' Representative may, at its election, participate in the
defense thereof at its sole cost and expense; provided, however, that if the
Indemnified Parties shall fail to defend any such legal action or other claim,
then the Stockholders' Representative may defend, through counsel of its own
choosing, such legal action or other claim, and so long as it gives Siemens at
least 15 days' notice of the terms of the proposed settlement thereof and
permits Siemens to then undertake the defense thereof, except as set forth
below, settle such legal action or other claim and recover out of the Indemnity
Amount the amount of such settlement or of any judgment and the costs and
expenses of such



                                      -47-
<PAGE>

defense. Neither Siemens nor the Stockholders' Representative shall compromise
or settle any such legal action or other claim without the prior written consent
of the other, which consent shall not be unreasonably withheld, except that
under no circumstances shall Siemens be required to consent to the entry of an
order for injunctive or other non-monetary relief. All costs and expenses
reasonably incurred in defending any such third party legal action or other
claim, including the amount of any settlement or of any judgment, shall be paid
out of the Indemnity Amount.

     7.7 Dispute Resolution: Negotiation, Mediation and Arbitration.

     (a) The Parties shall attempt to resolve any dispute arising out of or
relating to this Agreement promptly by negotiation in good faith between
executives who have authority to settle the dispute. Any Party shall give any
other Party written notice of any dispute not resolved in the ordinary course of
business. Within 7 days after delivery of such notice, the Party receiving
notice shall submit to the other a written response thereto. The notice and the
response shall include: (i) a statement of each Party's position(s) regarding
the matters(s) in dispute and a summary of arguments in support thereof, and
(ii) the name and title of the executive who will represent that Party and any
other Person who will accompany that executive.

     (b) Within 14 days after delivery of the notice, the designated executives
shall meet at a mutually acceptable time and place, and thereafter, as often as
they reasonably deem necessary, to attempt to resolve the dispute. All
reasonable requests for information made by one Party to any other shall be
honored in a timely fashion. All negotiations conducted pursuant to this Section
7.7 (and any of the Parties' submissions in contemplation hereof) shall be kept
confidential by the Parties and shall be treated by the Parties and their
representatives as compromise and settlement negotiations under the Federal
Rules of Evidence and any similar state rules.

     (c) If the matter in dispute has not been resolved within 30 days after
delivery of the notice, the dispute shall be submitted to non-binding mediation
in accordance with the then-current Model Procedure for Mediation of Business
Disputes of the CPR Institute for Dispute Resolution. The mediation shall be
conducted within 30 days of the time the mediator is selected. Unless otherwise
agreed, the parties will select a mediator from the CPR Panels of Distinguished
Neutrals; provided, however, that if no mediator from that list can be mutually
agreed upon, each Party will submit to the CPR its own list of acceptable
mediators from the CPR Panels of Distinguished Neutrals and the CPR shall
appoint one of those listed as the mediator for the Parties. The costs of the
mediation, including the mediator's fees, shall be borne equally by the Parties
to the dispute.



                                      -48-
<PAGE>

     (d) If the matter in dispute has not been resolved within 30 days after the
selection of the mediator, either Party (the "claimant") may submit the dispute
to binding arbitration to the New York, New York office of the American
Arbitration Association ("AAA") in accordance with the procedures set forth in
the Commercial Arbitration Rules of the AAA, revised and effective July 1, 1996.

     (e) The Commercial Arbitration Rules of the AAA, revised and effective July
1, 1996, as modified or revised by the provisions of this Section 7.7, shall
govern any arbitration proceeding hereunder. The arbitration shall be conducted
by three arbitrators selected pursuant to Rule 13 of the Commercial Arbitration
Rules, and prehearing discovery shall be permitted if and only to the extent
determined by the arbitrator to be necessary in order to effectuate resolution
of the matter in dispute. The arbitrator's decision shall be rendered within 30
days of the conclusion of any hearing hereunder and the arbitrator's judgment
and award may be entered and enforced in any court of competent jurisdiction.

     (f) Resolution of disputes under the procedures of this Section 7.7 shall
be the sole and exclusive means of resolving disputes arising out of or relating
to this Agreement; provided, however, that nothing herein shall preclude the
Parties from seeking in any court of competent jurisdiction temporary or interim
injunctive relief to the extent necessary to preserve the subject matter of the
dispute pending resolution under this Section 7.7.

     7.8 Exclusive Remedy. The indemnification provided in this Section 7 shall
be the sole and exclusive remedy available following the Closing to the
Indemnified Parties for the subject matter covered by such indemnification and
any claim arising under this Agreement.

     7.9 Tax Matters. Prior to the filing of any Income Tax Return solely with
respect to the Company and/or any of its Subsidiaries due after the Measurement
Date (with regard to extensions) with respect to any taxable year or other
taxable period beginning prior to the Measurement Date, and no later than thirty
(30) days prior to the due date for filing such Tax Return, Siemens shall
provide the Stockholders' Representative with a draft of such Tax Return, and
any related work papers, for review. No later than ten (10) days prior to the
due date for filing such Tax Return, the Stockholders' Representative shall
notify Siemens with any proposed modifications to such Tax Return. Such
modifications to the Tax Return shall be made by Siemens in its reasonable
discretion prior to filing as long as there is a reasonable basis for the filing
position requested. In any event, Siemens shall file all Tax Returns due after
the Measurement Date with respect to taxable years beginning prior to the
Measurement Date consistent with the Company's past practices to the extent
permitted by applicable law. Notwithstanding the foregoing, nothing contained in
this Agreement shall permit the Stockholders' Representative to receive nor
obligate Siemens to deliver to the Stockholders' Representative any consolidated
or other Tax Return or Income



                                      -49-
<PAGE>

Tax Return of Siemens or any other Subsidiary or Affiliate of Siemens (other
than a Tax Return relating solely to the Company and/or any of its
Subsidiaries).

          (i) Siemens shall not amend, or cause or permit the Company or any
     Subsidiary to amend, any Income Tax Return filed with respect to any
     taxable year or other taxable period beginning prior to the Measurement
     Date without the prior written consent of the Stockholders' Representative,
     which consent shall not be unreasonably withheld. Siemens and the
     Stockholders' Representative agree to consult and resolve in good faith any
     disagreement regarding the withholding of consent by the Stockholders'
     Representative, it being understood and agreed that in the absence of any
     such resolution, any and all such disagreements shall be resolved in a
     manner consistent with the procedures described in Section 7.7.

          (ii) Any overpayment in respect of Taxes relating to any taxable year
     or other taxable period (or portion thereof, as determined below in clause
     (c)) ending on or before the Measurement Date shall be for the benefit of
     the Stockholders; provided that, any overpayment of Taxes attributable to
     the fiscal 1994 through 1996 taxable years of the Company or its
     Subsidiaries shall be for the benefit of Siemens to the extent that such
     overpayments are reflected as an asset on the balance sheet (as of the
     close of business on the Measurement Date) prepared pursuant to Section
     2.2. Upon written notification to Siemens, the Stockholders'
     Representative, at its own expense, will be permitted to pursue any
     overpayment to which it is entitled; provided that any action on the part
     of the Stockholders' Representative shall not increase any Tax Liability of
     Siemens, the Company or any of their respective Subsidiaries in any period
     ending after the Measurement Date (in which event, such action shall
     require the prior written consent of Siemens, which shall not be
     unreasonably withheld).

     (a) Notwithstanding Section 7.2, no claim for indemnification shall be
permitted for any Losses resulting solely from the failure of Siemens or the
Company or any Subsidiary to timely file any Tax Return required to be filed
(with extensions) after the Measurement Date or timely pay any Taxes required to
be paid after the Measurement Date.

     (b) Siemens and the Company (and/or the Company's Subsidiaries) will, to
the extent permitted by applicable law, elect with the relevant Tax authority to
close the taxable year of the Company and its Subsidiaries on the Measurement
Date. For purposes of this Agreement, in the case of any Taxes in respect of a
taxable period that begins on or before the Measurement Date and ends after the
Measurement Date, the portion of such Tax attributable to the pre-Measurement
Date period shall (i) in the case of real property or other similar Taxes that
are fixed and periodic in nature, be the amount of such Taxes for the entire
period multiplied by a fraction, the numerator of which is the number of days in
the period ending on the Measurement Date, and the denominator of which is the
number of days in the entire period; and



                                      -50-
<PAGE>

(ii) in the case of all other Taxes, be determined on the basis of an interim
closing of the books at the end of the Measurement Date. For purposes of clause
(i) of the preceding sentence, any credits against Tax shall be prorated based
upon the fraction employed in such clause (i).

     (c) Siemens shall not make an election pursuant to Section 338 of the Code
with respect to the Company or any Subsidiary without the prior written consent
of the Stockholders' Representative.

     8. Termination; Effect of Termination.

     8.1 Termination. This Agreement may be terminated, and the transactions
contemplated hereby may be abandoned whether prior to or after the adoption of
this Agreement by the Company's stockholders if:

          (i) at any time 90 days following the date of this Agreement if the
     Merger shall not have been consummated on or prior to such date and such
     failure to consummate the Merger is not caused by a breach of this
     Agreement by the terminating party;

          (ii) there has been a material breach of this Agreement on the part of
     the non-terminating party and either (x) the non-terminating party fails to

     terminating party or (y) the breach is not reasonably capable of being
     cured within 30 days after notice thereof; or

     (c) at any time prior to the Initial Purchase Date, by Siemens upon the
occurrence of a Trigger Event (as defined in Section 8.2).

     8.2 Effect of Termination. (a) If this Agreement is validly terminated by
either the Company or Siemens pursuant to Section 8.1, this Agreement will
forthwith become null and void and there will be no liability or obligation on

sentatives or affiliates), except (i) that the provisions of Sections 5.3(b) and
9 will continue to apply following any such termination and (ii) as provided in

     (b) If (i) Siemens terminates this Agreement pursuant to (A) Section
8.1(b)(ii) or (B) Section 8.1(c), (ii) after the date hereof and prior to such

announced an intention to make a proposal for an Acquisition Transaction and
(iii) the Company consummates an Acquisition Transaction or enters into a
definitive agreement with respect to an Acquisition Transaction within 12 months
following such termination, then the Company shall pay to Siemens a termination
fee in the amount of $5 million upon the closing of such Acquisition Transition.
The termination fee shall be payable not later than two business days after the
closing of such Acquisition Transaction, by wire transfer of immediately
available funds to an account designated by Siemens. If the termination fee is
not paid within two business days after the due date as provided above, (i) the
termination fee will bear interest at the rate of 12% per year (or if less, the
highest legally permissible rate) from such date until paid and (ii) the Company
will pay for all attorneys' fees and expenses incurred by Siemens in connection
with collecting such overdue amounts.

     (c) For purposes of this Agreement, a "Trigger Event" means any of the
following events: (i) the Company shall have entered into, or shall have
publicly announced its intention to enter into, a definitive agreement or
agreement in principle with respect to any Acquisition Transaction other than

the Company or any committee thereof shall have withdrawn its approval or
recommendation of this Agreement or the Merger, or modified its approval or

thereof shall have made any recommendation with respect to an Acquisition
Transaction by any Person (other than Siemens or Acquisition) other than a
recommendation rejecting or against such Acquisition Transaction; or (iv) the
Company receives a proposal with respect to an Acquisition Transaction by any
Person (other than Siemens or Acquisition), and the Company's Board of Directors
takes a neutral position or makes no recommendation with respect to such
Acquisition Transaction after a reasonable amount of time (and in no event more
than five business days) has elapsed for the Company's Board of Directors to
review and make a recommendation with respect to such proposal consistent with
the Board's fiduciary duties.

     This Agreement is being entered into pursuant to an Agreement and Plan of
Merger dated as of March 13, 2000 (the "Merger Agreement"; capitalized terms not

among Siemens, Emilia Acquisition Corp., a Delaware corporation ("Acquisition"),
and the Company in order to provide for the deposit with the Escrow Agent of
funds that will be held and disbursed, as hereinafter provided and as provided

Representative and Siemens of its receipt of an Objection Certificate not later

to the consent of the Stockholders' Representative, which consent shall not be
unreasonably withheld.

accordance with the provisions of the Merger Agreement, as instructed in writing

requesting the same, it shall have the right to interplead Siemens and the
Stockholders' Representative in any court of competent jurisdiction and request
that such court determine its rights and duties hereunder;

Stockholders' Representative, on behalf of the holders of Company Common Stock,
shall reimburse and indemnify the Escrow Agent for, and hold it harmless
against, any loss, damages, judgment, fine, penalty, claim, demand, settlement,
cost or expense, including but not limited to reasonable attorneys' fees,
reasonably incurred by the Escrow Agent in connection with the Escrow Agent's
acceptance and administration of this Agreement and its performance of its
duties and obligations under this Agreement, as well as the reasonable costs and
expenses of defending against any claim or liability relating to this Agreement;
provided that notwithstanding the foregoing, neither Siemens nor the
Stockholders' Representative shall be required to indemnify the Escrow Agent for
any such loss, liability, cost or expense arising as a result of the Escrow
Agent's willful misconduct or gross negligence or breach of this Agreement and
provided, further that in no event shall the Stockholders' Representative, on
behalf of the holders of the Company Common Stock, be responsible to reimburse,
indemnify or hold the Escrow Agent harmless against any liabilities with respect
to income Taxes which, for purposes of this Agreement, are the sole

     (a) The Escrow Agent may resign as such 30 calendar days following the
giving of prior written notice thereof to Siemens and the Stockholders'
Representative. In addition, the Escrow Agent may be removed and replaced on a
date designated in a written instrument signed by Siemens and the Stockholders'
Representative and delivered to the Escrow Agent. Notwithstanding the foregoing,

as such as provided in paragraph (c) below, in the case of a resignation, prior
to the expiration of 30 calendar days following the date of a notice of
resignation or, in the case of a removal, on the date designated for the Escrow
Agent's removal, as the case may be, because Siemens and the Stockholders'
Representative are unable to agree on a successor escrow agent, or for any other
reason, the Escrow Agent may petition a court of competent jurisdiction to
select a successor and any such resulting appointment shall be binding upon all
of the parties to this Agreement.

     (c) Upon written acknowledgment by a successor escrow agent appointed in
accordance with the foregoing provisions of this Section 9 of its agreement to
serve as escrow agent hereunder and the receipt of the property then comprising
the Escrow Fund, the Escrow Agent shall be fully released and relieved of all
duties, responsibilities and obligations under this Agreement, subject to the
proviso contained in clause (iii) of Section 6, and such successor escrow agent
shall for all purposes hereof be the Escrow Agent.

Corporation, a Delaware corporation ("Siemens"), Entex Information Services,
Inc., a Delaware corporation (the "Company"), ChaseMellon Shareholder Services,
L.L.C., a New Jersey limited liability company, as escrow agent (the "Tax Escrow
Agent"), and Dort A. Cameron, III (or such successor person selected as
Stockholders' Representative pursuant to the Merger Agreement (as defined below)
the "Stockholders' Representative").

                                    RECITALS

     A. This Agreement is being entered into pursuant to an Agreement and Plan
of Merger dated as of March 13, 2000 (the "Merger Agreement"; capitalized terms
not defined herein shall have the meanings ascribed to them in the Merger
Agreement) among Siemens, Emilia Acquisition Corp., a Delaware corporation
("Acquisition"), and the Company in order to provide for the deposit with the
Tax Escrow Agent of funds that will be held and disbursed, as hereinafter
provided and as provided in the Merger Agreement, to make payments to Siemens
and (to the extent of any remaining funds) to make payments to certain former
holders of Company Common Stock.

     B. For purposes of clarification, the funds deposited with the Tax Escrow
Agent pursuant to this Agreement are intended to provide Siemens with
indemnification from and protection against potential Losses resulting from the
outcome of the matters described in that certain revenue agent report (the
"RAR") that was submitted to the U.S. Congressional Joint Committee on Taxation
(the "Joint Committee") on January 5, 2000, a copy of which is attached hereto
as Exhibit A, and certain state and local tax matters related thereto
(collectively, the "Tax Matters"), following the audit of the Company with
respect to its fiscal 1994, 1995 and 1996 tax years (collectively, the "Audited
Tax Years"), conducted by the Internal Revenue Service (the "IRS").

     C. The parties have procured and paid for certain insurance policies,
copies of which are attached hereto as Exhibit B (collectively, the "Insurance
Policies"), to provide indemnification and protection against potential Losses
resulting from the Tax Matters in excess of, and in certain circumstances in
place of, the funds deposited hereunder, and intend to clarify their rights with
respect to participation in and control of all actions, proceedings and claims
relating to the Tax Matters.

     NOW, THEREFORE, the parties hereby agree as follows:

     1. Appointment of the Tax Escrow Agent; Deposit of Tax Escrow Amount.
Siemens, the Company and the Stockholders' Representative hereby constitute and
appoint the Tax Escrow Agent as, and the Tax Escrow Agent hereby agrees to

acknowledges receipt of an executed copy of the Merger Agreement and copies of
the RAR and the Insurance Policies. Pursuant to the Merger Agreement, funds in
the amount of _________________ ($__________) (the "Tax Escrow Amount") have
been or are to be deposited with the Tax Escrow Agent by Siemens.

     2. The Tax Escrow Fund. The Tax Escrow Amount and all earnings thereon (the
Tax Escrow Amount and all such earnings being referred to herein together as the
"Tax Escrow Fund") shall be held by the Tax Escrow Agent as a trust fund in a
separate account maintained for the purpose, on the terms and subject to the
conditions of this Agreement. The Tax Escrow Fund shall not be subject to lien
or attachment by any creditor of any party hereto and shall be used solely for
the purpose set forth in this Agreement. Except as set forth in Section 8
hereof, amounts held in the Tax Escrow Fund shall not be available to, and shall
not be used by, the Tax Escrow Agent to set off any obligations of Siemens, the
Company, the Stockholders' Representative or any former holder of Company Common
Stock owing to the Tax Escrow Agent in any capacity.

     3. Investment of the Tax Escrow Fund; Taxes.

     (a) Unless otherwise directed in writing by Siemens and the Stockholders'
Representative, the Tax Escrow Agent shall invest and reinvest all cash funds
held from time to time as part of the Tax Escrow Fund, in bonds or other
fixed-income securities, the interest on which is not subject to U.S. federal
income tax (including alternative minimum tax) or to New York City or New York
State income tax; or if such securities are not available for purchase, in
obligations of, or guaranteed by, the government of the United States of America
or any State thereof or the District of Columbia, or agencies of any of the
foregoing, having maturities of not greater than 90 days (or, if earlier, the
Termination Date (as hereinafter defined)); provided that such bonds or other
obligations are rated at least A by Moody's Investors Service, Inc. ("Moody's")
and A by Standard & Poor's Corporation ("S&P").

     (b) It is not anticipated that Taxes will be payable in respect of earnings
on the Tax Escrow Fund; however, to the extent that such Taxes are payable, they
shall be the obligation of and shall be paid when due by Siemens but Siemens
shall be entitled to be reimbursed the amount of any and all such Tax payments
from the Tax Escrow Fund in accordance with Section 5(a). The Tax Escrow Agent
shall have no duty or obligation with respect to notifying any party of any
taxes due or monitoring the payment of any taxes. Siemens hereby agrees to
indemnify and hold harmless the Tax Escrow Agent from and against any liability
arising from such taxes, including any failure to pay such taxes.

     4. Claims Against the Tax Escrow Fund. On the Release Date (as hereinafter
defined), Siemens will deliver to the Tax Escrow Agent a certificate in
substantially the form of Annex I attached hereto (a "Resolution Certificate").
The Tax Escrow Agent shall give written notice to the Company and the
Stockholders' Representative of its receipt of the Resolution



                                      -2-

portion of the amounts claimed in the RAR; provided such refund has been
approved by the Joint Committee; (ii) the date the Company and the IRS reach a
settlement or compromise of all open issues between the Company and the IRS with
respect to the Audited Tax Years that is fully effective and requires no further
governmental authorization, whether or not such settlement or compromise closes
the applicable statute of limitations with respect to the Audited Tax Years, and
any agreed upon refunds are received by the Company and/or any agreed upon
assessments by the IRS, along with any assessments relating to Other Income Tax
(as defined in the Insurance Policies) resulting solely from the settlement or
compromise with the IRS have been paid; and (iii) the date that is 15 business
days after the final expiration of all limitation periods (as extended or
tolled) applicable under the Code with respect to the Audited Tax Years.

     5. Release of Tax Escrow Fund.

     (a) Earnings Tax Release. To the extent that Taxes in respect of earnings
on the Tax Escrow Fund become due and payable by Siemens prior to the
Termination Date (as hereinafter defined), Siemens shall notify the
Stockholders' Representative and the Tax Escrow Agent and upon receipt of such
written notice executed by Siemens and the Stockholders' Representative, the Tax

Representative, which consent shall not be unreasonably withheld.

expenses in connection with any action, proceeding or claim relating solely to
the Tax Matters, Siemens shall notify the Stockholders' Representative and the

however,



                                      -3-
<PAGE>

that prior to the Release Date, no amounts shall be released from the Tax Escrow
Fund for the reimbursement of the costs or expenses of Siemens or the
Stockholders' Representative unless such costs and expenses are characterized as
Specified Losses (as such term is defined in the Insurance Policies).

     (c) Termination Date. The Tax Escrow Agent shall on the date that is no
later than five business days following its receipt of a Resolution Certificate
(the "Termination Date"), transfer from the Tax Escrow Fund to (i) Siemens, the
amount of the assessment by the IRS for Federal Specified Losses (as defined in
the Insurance Policies), together with any Other Income Tax assessments
resulting solely from a settlement or compromise with the IRS or other
Governmental Entity of the Tax Matters as set forth in the Resolution
Certificate and (ii) to a separate sub-account (the "Release Account") an amount
equal to (x) the remaining balance of the Tax Escrow Fund less (y) (A) the sum
of the amounts released or to be released pursuant to paragraphs (a) and (b)
above and (B) the fees and expenses of the Tax Escrow Agent to be deducted from
the Tax Escrow Fund as set forth in Section 8. Funds (if any) deposited and held
from time to time pursuant to this Agreement in the Release Account shall be
released (i) first, to the extent the sum of (x) the Stockholders'
Representative Expense Amount actually paid to the Stockholders' Representative
pursuant to the Merger Agreement and (y) amounts released to the Stockholders'
Representative pursuant to paragraph (b) above is less than $500,000, to the
Stockholders' Representative in an amount equal to the amount by which such
amount referred to in the immediately preceding classes (x) and (y) is less than
$500,000 and (ii) second, to the extent of all remaining funds, to the former
holders of Company Common Stock entitled thereto in accordance with the
provisions of the Merger Agreement, as instructed in writing by the
Stockholders' Representative. After all funds have been disbursed from the
Escrow Account and the Release Account, this Agreement (other than Sections 6, 7
and 8) shall automatically terminate.

     6. Duties and Obligations of the Tax Escrow Agent. The duties and
obligations of the Tax Escrow Agent shall be limited to and determined solely by
the provisions of this Agreement and the certificates delivered in accordance
herewith, and the Tax Escrow Agent is not charged with knowledge of or any
duties or responsibilities in respect of any other agreement or document
(including the Merger Agreement, the RAR and the Insurance Policies). In
furtherance and not in limitation of the foregoing:

     (a) the Tax Escrow Agent shall not be liable for any loss of interest or
any penalty sustained or imposed as a result of investments, reinvestments,
sales or liquidations made hereunder in accordance with the terms hereof,
including any liquidation of any investment of the Tax Escrow Fund prior to its
maturity effected in order to make a payment (including any payment of taxes)
required by the terms of this Agreement;

     (b) the Tax Escrow Agent shall be fully protected and shall incur no
liability in relying in good faith upon any written certification, notice,
direction, request, waiver, consent, receipt or other document that the Tax
Escrow Agent reasonably believes to be genuine and duly



                                      -4-
<PAGE>

authorized, executed and delivered (including, but not limited to, any
documentation from the arbitration panel appointed pursuant to Section 7.7 of
the Merger Agreement);

     (c) the Tax Escrow Agent shall not be liable for any error of judgment, or
for any action taken, suffered or omitted by it, or for any mistake in fact or
law, or for anything that it may do or refrain from doing in connection
herewith; provided, however, that notwithstanding any other provision in this
Agreement, (a) the Tax Escrow Agent shall be liable for its willful misconduct
or gross negligence or breach of this Agreement; and (b) in no event shall the
Tax Escrow Agent be liable for special, punitive, indirect, consequential or
incidental loss or damage of any kind whatsoever (including, but not limited to,
lost profits), even if the Tax Escrow Agent has been advised of the likelihood
of such loss or damage;

     (d) the Tax Escrow Agent may seek the advice of legal counsel selected with
reasonable care in the event of any dispute or question as to the construction
of any of the provisions of this Agreement or its duties hereunder, and it shall
incur no liability and shall be fully protected in respect of any action taken,
omitted or suffered by it in good faith in accordance with the opinion of such
counsel;

     (e) in the event that the Tax Escrow Agent shall in any instance, after
seeking the advice of legal counsel pursuant to the immediately preceding
clause, in good faith be uncertain as to its duties or rights hereunder, it
shall be entitled to refrain from taking any action in that instance and its
sole obligation, in addition to those of its duties hereunder as to which there
is no such uncertainty and which are not impacted by such uncertainty, shall be
to keep safely all property held in the Tax Escrow Fund until it shall be
directed otherwise in writing by each of the parties hereto or by a final,
nonappealable order of a court of competent jurisdiction; provided, however, in
the event that the Tax Escrow Agent has not received such written direction or
court order within 180 calendar days after requesting the same, it shall have
the right to interplead Siemens and the Stockholders' Representative in any
court of competent jurisdiction and request that such court determine its rights
and duties hereunder;

     (f) the Tax Escrow Agent may execute any of its powers or responsibilities
hereunder and exercise any rights hereunder either directly or by or through
agents or attorneys selected with reasonable care; and

     (g) nothing in this Agreement shall be deemed to impose upon the Tax Escrow
Agent any duty to qualify to do business in any jurisdiction other than the
State of New York or to act as fiduciary or otherwise and the Tax Escrow Agent
shall not be responsible for and shall not be under a duty to examine into or
pass upon the validity, binding effect, execution or sufficiency of this
Agreement or of any agreement amendatory or supplemental hereto.

     7. Cooperation. Siemens and the Stockholders' Representative shall provide
to the Tax Escrow Agent all instruments and documents within their respective
powers to provide that are necessary for the Tax Escrow Agent to perform its
duties and responsibilities hereunder.



                                      -5-
<PAGE>

     8. Fees and Expenses; Indemnity. The fees, costs and expenses of the Tax
Escrow Agent for its services hereunder, including the preparation and delivery
of all Form 1099s and other documentation required to be delivered by the IRS,
shall be deducted by the Tax Escrow Agent directly from the Tax Escrow Fund
prior to any payments or releases pursuant to Section 5; provided that in no
event shall such fees exceed [$5,000] per year. Each of Siemens and the
Stockholders' Representative, on behalf of the holders of Company Common Stock,
shall reimburse and indemnify the Tax Escrow Agent for, and hold it harmless
against, any loss, damages, judgment, fine, penalty, claim, demand, settlement,
cost or expense, including but not limited to reasonable attorneys' fees,
reasonably incurred by the Tax Escrow Agent in connection with the Tax Escrow
Agent's acceptance and administration of this Agreement and its performance of
its duties and obligations under this Agreement, as well as the reasonable costs
and expenses of defending against any claim or liability relating to this
Agreement; provided that notwithstanding the foregoing, neither Siemens nor the
Stockholders' Representative shall be required to indemnify the Tax Escrow Agent
for any such loss, liability, cost or expense arising as a result of the Tax
Escrow Agent's willful misconduct or gross negligence or breach of this
Agreement and provided, further that in no event shall the Stockholders'
Representative, on behalf of the holders of the Company Common Stock, be
responsible to reimburse, indemnify or hold the Tax Escrow Agent harmless
against any liabilities with respect to income Taxes which, for purposes of this
Agreement, are the sole responsibility of Siemens as provided in Section 3(b).

     9. Proceeding Relating to Tax Matters. Notwithstanding anything to the
contrary contained in the Merger Agreement, Siemens and the Stockholders'
Representative hereby agree that the following shall apply with respect to all
actions, proceedings and other claims relating solely to (or in the case of
actions, proceedings and other claims not relating solely to but including Tax
Matters, that portion of the action, proceeding or claim relating solely to) the
Tax Matters:

     (a) Until such time as the dollar amount of any dispute or claim with the
IRS and any other Governmental Entity with respect to the Tax Matters is greater
than the amounts then available in the Tax Escrow Fund (such amount being the
"Indemnity Cushion"), the Stockholders' Representative shall have the right to
conduct and control, through counsel of its own choosing, reasonably acceptable
to Siemens, any action, proceeding or other claim relating solely to (or in the
case of actions, proceedings and other claims not relating solely to but
including Tax Matters, that portion of the action, proceeding or claim relating
solely to) the Tax Matters, but Siemens may, at its election, participate in any
such action, proceeding or claim at its sole cost and expense; provided,
however, that if the Stockholders' Representative shall fail to promptly assume
and thereafter diligently prosecute any such action, proceeding or claim, then
Siemens may assume, through counsel of its own choosing, the control and conduct
of such action, proceeding or claim, subject to the right of the Stockholders'
Representative to participate therein as provided in Section 9(b). If the
Stockholders' Representative has control of the action, proceeding or claim on
the date of proposed settlement, the Stockholders' Representative may settle any
action, proceeding or claim, the control and conduct of



                                      -6-
<PAGE>

which it is entitled to hereunder, but only with the written consent of Siemens,
such consent not to be unreasonably withheld or delayed.

     (b) Subject to the limitations and procedures contained in the Insurance
Policies, from and after the first time the dollar amount of any dispute or
claim with the IRS and any other Governmental Entity with respect to the Tax
Matters is greater than the Indemnity Cushion, Siemens shall have the right to
assume control and conduct, through counsel of its own choosing, reasonably
acceptable to the Stockholders' Representative, of all pending actions,
proceedings or other claims with respect to the Tax Matters (including actions,
proceedings and claims whose defense hitherto has been controlled by the
Stockholders' Representative) and thereafter to conduct and control, through
counsel of its own choosing, reasonably acceptable to the Stockholders'
Representative, any and all actions, proceedings and claims relating to the Tax
Matters that may thereafter arise; provided, that the Stockholders'
Representative may, at its election, continue to participate or participate, as
the case may be, in any such action, proceedings or claim, at its sole cost and
expense. Subject to the limitations and procedures contained in the Insurance
Policies, Siemens may settle or otherwise compromise any action, proceeding or
claim which they are entitled to control hereunder, but only with the prior
written consent of the Stockholders' Representative, such consent not to be
unreasonably withheld or delayed.

     For purposes of clarification, Siemens and the Stockholders' Representative
agree that in all actions, proceedings and claims not related solely to (and, in
the case of actions, proceedings and other claims not relating solely to, but
including Tax Matters, that portion of the action, proceeding or claim not
relating solely to) the Tax Matters, the provisions of Section 7.6 of the Merger
Agreement shall apply.

     10. Resignation and Removal of the Tax Escrow Agent.

     (a) The Tax Escrow Agent may resign as such 30 calendar days following the
giving of prior written notice thereof to Siemens and the Stockholders'
Representative. In addition, the Tax Escrow Agent may be removed and replaced on
a date designated in a written instrument signed by Siemens and the
Stockholders' Representative and delivered to the Tax Escrow Agent.
Notwithstanding the foregoing, no such resignation or removal shall be effective
until a successor escrow agent has acknowledged its appointment as such as
provided in paragraph (c) below. In either event, upon the effective date of
such resignation or removal and upon receipt by the Tax Escrow Agent of any
fees, costs and expenses owed or due to it, if any, hereunder the Tax Escrow
Agent shall deliver the property comprising the Tax Escrow Fund to such
successor escrow agent, together with such records maintained by the Tax Escrow
Agent in connection with its duties hereunder and other information with respect
to the Tax Escrow Fund as such successor may reasonably request.

     (b) If a successor escrow agent shall not have acknowledged its appointment
as such as provided in paragraph (c) below, in the case of a resignation, prior
to the expiration of 30 calendar days following the date of a notice of
resignation or, in the case of a removal, on the



                                      -7-
<PAGE>

date designated for the Tax Escrow Agent's removal, as the case may be, because
Siemens and the Stockholders' Representative are unable to agree on a successor
escrow agent, or for any other reason, the Tax Escrow Agent may petition a court
of competent jurisdiction to select a successor and any such resulting
appointment shall be binding upon all of the parties to this Agreement.

     (c) Upon written acknowledgment by a successor escrow agent appointed in
accordance with the foregoing provisions of this Section 10 of its agreement to
serve as escrow agent hereunder and the receipt of the property then comprising
the Tax Escrow Fund, the Tax Escrow Agent shall be fully released and relieved
of all duties, responsibilities and obligations under this Agreement, subject to
the proviso contained in clause (iii) of Section 6, and such successor escrow
agent shall for all purposes hereof be the Tax Escrow Agent.

     11. Notices. All notices, requests and other communications hereunder must

Private Letter Ruling 8640021 (July 1, 1986), Siemens and the Stockholders'
Representative agree that the establishment of this Tax Escrow Fund amounts to a

inconsistent position on any Tax Return or for any other Tax purpose unless
required by applicable law.

     13. Amendments, etc. This Agreement may be amended or modified, and any of

future occasion.

     14. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to a contract

construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed entirely within such State.

     15. Business Day. For all purposes of this Agreement, the term "business
day" shall mean a day other than Saturday, Sunday or any day on which banks

deemed an original, but all of which together will constitute one and the same
instrument.

                             STOCKHOLDERS AGREEMENT

     STOCKHOLDERS AGREEMENT (this "Agreement"), dated as of March 13, 2000, by
and among SIEMENS CORPORATION, a Delaware corporation ("Siemens"), EMILIA

subsidiary of Siemens, and the Persons listed on the signature pages hereto

                                    RECITALS

     A. Each of the Stockholders is, as of the date hereof, the record and
beneficial owner of the number of shares of capital stock, of Entex Information
Services, Inc., a Delaware corporation (the "Company"), set forth on Annex I
hereto.

     B. Siemens, Acquisition and the Company concurrently herewith are entering
into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger

same meanings ascribed to those terms in the Merger Agreement), which provides,
among other things, for the merger (the "Merger") of Acquisition with and into
the Company upon the terms and subject to the conditions set forth in the Merger
Agreement.

     C. As a condition to the willingness of Siemens and Acquisition to enter
into the Merger Agreement, and in order to induce Siemens and Acquisition to
enter into the Merger Agreement, the Stockholders have agreed to enter into this
Agreement.

     NOW, THEREFORE, in consideration of the execution and delivery by Siemens
and Acquisition of the Merger Agreement and the foregoing and the mutual
representations, warranties, covenants and agreements set forth herein and
therein, and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

     1. Representations and Warranties of the Stockholders. Each of the
Stockholders hereby represents and warrants to Siemens and Acquisition,
severally and not jointly, as follows:

     (a) Such Stockholder is the record and beneficial owner of the shares of
capital stock of the Company (as may be adjusted from time to time pursuant to
Section 7 hereof, the "Shares") set forth opposite the Stockholder's name on
Annex I to this Agreement.



<PAGE>

     (b) Such Stockholder has the legal capacity to execute and deliver this
Agreement and to consummate the transactions contemplated hereby.

     (c) This Agreement has been duly authorized by all requisite action
(corporate, partnership or other) on the part of such Stockholder, has been
validly executed and delivered by such Stockholder and constitutes the legal,
valid and binding obligation of such Stockholder, enforceable against such
Stockholder in accordance with its terms, except as limited by bankruptcy,
insolvency, reorganization, moratorium or other laws affecting enforcement of
creditors' rights generally and by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     (d) The execution and delivery of this Agreement by such Stockholder do
not, and the performance by such Stockholder of the Stockholder's obligations
under this Agreement will not, (i) conflict with, result in a violation or
breach of, constitute (with or without notice or lapse of time or both) a
default under, result in or give to any person any right of termination,
cancellation, modification or acceleration of, or result in the creation or
imposition of any Lien upon any of the assets or properties of such Stockholder
under, any of the terms, conditions or provisions of (A) the certificate or
article of incorporation or bylaws or other comparable organizational documents
of the Stockholder if applicable or (B) (x) any law or order of any governmental
or regulatory authority applicable to such Stockholder or any of the
Stockholder's assets or properties, or (y) any contract to which the Stockholder
is a party or by which the Stockholder or any of the Stockholder's assets or
properties is bound, excluding from the foregoing clauses (x) and (y) conflicts,
violations, breaches, defaults, terminations, modifications, accelerations and
creations and impositions of Liens which, individually or in the aggregate,

obligation of each of Siemens and Acquisition, enforceable against each of them
in accordance with its terms, except as limited by bankruptcy, insolvency,

creditors' rights generally and by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law).

     (c) The execution and delivery of this Agreement by Siemens and Acquisition
do not, and the performance by Siemens and Acquisition of their obligations
hereunder and the consummation of the transactions contemplated hereby will not,
(i) conflict with, result in a violation or breach of, constitute (with or
without notice or lapse of time or both) a default under, result in or give to
any person any right of termination, cancellation, modification or acceleration
of, or result in the creation or imposition of any Lien upon any of the assets
or properties of Siemens or Acquisition under, any of the terms, conditions or
provisions of (A) the certificates or articles of incorporation or bylaws of
Siemens or Acquisition or (B) (x) any law or order of any governmental or
regulatory authority applicable to Siemens or Acquisition or any of their
respective assets or properties, or (y) any contract to which Siemens or
Acquisition is a party or by which Siemens or Acquisition or any of their
respective assets or properties is bound, excluding from the foregoing clauses
(x) and (y) conflicts, violations, breaches, defaults, terminations,
modifications, accelerations and creations and impositions of Liens which,

the transactions contemplated by this Agreement, or (ii) require any filing by
Siemens or Acquisition with, or any permit, authorization, consent or approval
of, any governmental or regulatory authority.

     3. Grant of Options.

     (a) Each Stockholder hereby irrevocably grants to Acquisition an exclusive
option (the "Call Option") to purchase all Shares of such Stockholder at the
Merger Price per Share specified in Section 2.1(c) of the Merger Agreement (the
"Option Price"), which Option shall be exercisable by Acquisition at any time
after the date hereof and prior to the termination of this Agreement.

     (b) If (i) the Information Statement has been filed with the SEC in
preliminary form in accordance with Section 5.4 of the Merger Agreement; (ii) a
period of twelve days has elapsed following such filing; (iii) the Company has
been advised by the staff of the SEC that it is in the process of reviewing the
Information Statement and notwithstanding the Company's reasonable efforts that
review has not been completed; and (iv) all of the conditions described in
Section 6.1 of the Merger Agreement (other than Section 6.1(e)) have been
satisfied, then

<PAGE>

the Stockholders shall have the option (the "Put Option", and together with the
Call Option, the "Options") to require Acquisition to purchase from the
Stockholders all, but not less than all, of the Shares of each Stockholder at
the Option Price. The Put Option may be exercised by the Stockholders at any
time beginning on the date on which the conditions specified in clauses (i)
through (iv) of the preceding sentence are satisfied until this Agreement is
terminated.

     (c) To exercise an Option, the exercising party shall send a written notice
("Exercise Notice") to each other party specifying the place and the time (which
shall be not less than two business days and not more than four business days
after the date of the Exercise Notice) for the closing of the purchase and sale
of the Shares in accordance with the exercise of the Option. The closing of the
purchase and sale of the Shares (the "Option Closing") pursuant to the exercise
of the Option shall take place at the place and at the time designated by the
exercising party in the Exercise Notice. The obligation of Siemens or its
designee to purchase the Shares at the Option Closing shall be subject to the
conditions that (i) all of the conditions described in Section 6.1 of the Merger
Agreement (other than Section 6.1(e)) shall have been satisfied and (ii) proper
arrangements shall have been made to give effect to the provisions of Section
1.6 of the Merger Agreement, and the securities law requirements described in
Section 1.6(b) shall have been satisfied.

     (d) At the Option Closing, each Stockholder shall sell, assign, convey and
transfer to Acquisition, each such Stockholder's Shares, free and clear of any
and all liens, claims, security interests, encumbrances, options or adverse
claims whatsoever, and each Stockholder shall deliver or cause to be delivered
to Acquisition a certificate or certificates representing the number of Shares
to be delivered by such Stockholder at the Option Closing, duly endorsed, or
accompanied by stock powers duly executed in blank, with all required transfer
tax stamps affixed thereto. Siemens shall procure that the applicable portions
of the Option Price are paid not later than the dates the corresponding portions
of the Merger Price per Share first are payable under the Merger Agreement.
Payment of each amount will be by wire transfer or certified or bank cashier's
check or checks.

     (e) In the event of any change in the Company's capital stock by reason of
any stock dividend, stock split, merger, consolidation, recapitalization,
combination, conversion, exchange of shares or dividend or other change in the
corporate or capital structure of the Company, which would have the effect of
diluting or changing Acquisition's rights hereunder, the number and kind of
shares or securities subject to the Options and the Option Price shall be
appropriately and equitably adjusted so that (i) Acquisition shall receive, at
the Option Closing, the number and class of shares or other securities or
property that Acquisition would have received and (ii) the Stockholders shall
receive, at the Option Closing, the consideration they would have received in
respect of the Shares purchasable upon exercise of the Options if the Options
had been exercised immediately prior to such event.

               SIEMENS TO ACQUIRE ENTEX INFORMATION SERVICES, INC.

Acquisition Bolsters Siemens IT Service GmbH Global Capability to Support
Mission Critical and E-Business IT Systems and Infrastructure

     New York and Munich, March 14, 2000 - Siemens has announced today that it
has entered into an agreement to acquire ENTEX Information Services, Inc. of Rye
Brook, NY. Upon closing the combined operations will be one of the strongest
independent IT service providers in North America, with worldwide revenues of
nearly $2.2 billion and approximately 13,000 employees.

     Terms of the agreement are detailed in the Addendum.

     The acquisition marks an important step in Siemens' IT Service strategy to
establish a truly global information technology consulting and infrastructure
support business focused on helping customers migrate to and gain maximum
advantage from rapidly advancing mission critical and e-business technologies.

     Closing is subject to regulatory review and the expiration of applicable
antitrust waiting periods.

     Paul Stodden, president and CEO of Siemens global IT Service business said:
"The acquisition will enable us to provide borderless information technology
services that offer customers the power and expertise they will need to leverage
the benefits of U.S. developed e-business technologies on a worldwide basis. We
are opening a global menu of possibilities to our North American and global
customers by focusing on complex systems and networks used for mission critical
systems and e-business solutions. This will position Siemens as one of the truly
global providers of platform- and vendor-independent information technology
services."

     John McKenna, CEO of ENTEX Information Services, Inc. said: "The business
logic of joining the Siemens organization results in an outstanding win-win for
our customers, employees and our company."

     "ENTEX will have the backing of one of the world's premiere technology
companies and access to resources that will permit its accelerated growth. We
are very excited about the prospects that lay before us and believe that joining
Siemens will significantly improve our ability to realize our vision.", he
concluded.

Addendum:  Consideration to be Received in the Merger

     Siemens will acquire in the merger all of the outstanding common stock of
ENTEX for an aggregate cash purchase price of $105 million less the following
deductions, without duplication:

     o    the amount by which ENTEX's current assets less total liabilities at
          the "Measurement Date" referred to below are less than ENTEX's current
          assets less total liabilities at September 26, 1999;

     o    the expenses of ENTEX in connection with the merger, including legal
          and financial advisor fees and expenses and bonus, severance and
          additional compensation costs;

     o    the $12.5 million premium which will be payable in connection with the
          redemption of ENTEX's 12-1/2% Senior Subordinated Notes due 2006;

     o    an amount equal to $32.2 million less the book value of ENTEX's
          Subordinated Debentures as of the Measurement Date. It is estimated
          that this deduction will be approximately $12.0 million.

     The first $20.0 million of the aggregate purchase price will be deposited
into an interest-bearing escrow to satisfy any indemnification claims by Siemens
relating to breaches of any representations, warranties or covenants in the
merger agreement. Any of these funds not utilized for such purposes (net of
escrow-related expenses) will be paid to the former ENTEX stockholders eighteen
months following the Measurement Date, except to the extent of any unresolved
indemnification claims as of such date.

     The next $20.0 million of the aggregate purchase price, if any, will be
deposited into an interest-bearing escrow to satisfy any tax liabilities and
related expenses relating to ENTEX's 1994, 1995 and 1996 fiscal years. Any of
these funds not utilized for such purposes (net of certain escrow-related
expenses) will be paid to the former ENTEX stockholders upon receipt of a refund
currently pending before the IRS with respect to these tax years or other


                                      -3-

resolution of such tax matters. While the timing of the refund or other
definitive resolution of these tax matters cannot be determined, it is not
anticipated to occur prior to June 30, 2000.

     The remainder of the aggregate purchase price, if any (after a $500,000
reserve that may be utilized by Dort A. Cameron, III, the Chairman and
controlling stockholder of ENTEX, for expenses in his capacity as stockholders'
representative) will be released to the former stockholders of ENTEX promptly
following the later of the resolution of the Closing Statement referred to below
or the effective time of the merger.

     Mr. Cameron, certain of his affiliates and John A. McKenna, ENTEX's Chief
Executive Officer, have granted to Siemens a call option to purchase 24,719,596
shares of ENTEX common stock in the aggregate, exercisable at any time at the
purchase price to be paid in the merger, payable at the same time(s) other
stockholders receive their consideration. In addition, Siemens has granted to
these stockholders the option to put their shares to Siemens for the same
purchase price in the event the Securities Exchange Commission reviews ENTEX's
Information Statement on Schedule 14C to be filed in connection with the merger
and the conditions to the merger are then satisfied.

     If either the call option or put option is exercised, the "Measurement
Date" will be the date shares of ENTEX common stock are purchased pursuant to
such exercise. If neither option is exercised, the "Measurement Date" will be
the effective time of the merger, which will occur promptly upon satisfaction of
the conditions to the merger. Holders of 7,104,148 shares of ENTEX common stock
have tag-along and drag-along rights and obligations. If either the call option
or the put option is exercised, Mr. Cameron will exercise his drag-along rights,
thereby requiring the holders of such shares to sell such shares to Siemens on
the same terms as his sale, including purchase price and timing of receipt of
payment.

     Within thirty days following the Measurement Date, Siemens will deliver to
Mr. Cameron, as the stockholders' representative, a Closing Statement setting
forth the calculation of the aggregate purchase price, based on the balance
sheet of ENTEX as of the Measurement Date. Mr. Cameron will have up to 15 days
to either approve or object to their Closing Statement. If he objects to their
Closing Statement, there is a dispute resolution mechanism in the merger
agreement that contemplates resolution of any objections within 40 days after
Mr. Cameron's objections, although actual resolution may take longer.

     Each share of ENTEX common stock will be entitled to receive its
proportionate share of the aggregate purchase price (as calculated in the manner
and at the times described above). As of March 9, 2000, there were 32,814,724
outstanding shares of ENTEX common stock. Because the final deductions to the
purchase price will not be known until the Closing Statement is agreed to, and
the total claims against the escrow amounts will not be finally known until the
end of the respective escrow periods, ENTEX cannot determine at this time what
either the aggregate purchase price or the purchase price per share will be.

     However, ENTEX estimates that the purchase price per share (including
amounts that will be subject to claims of Siemens under the two escrows) will be
between $1.20 and $1.50, and may be significantly less than such amount.

Redemption of the Outstanding Senior Subordinated Notes

     Pursuant to the terms of the merger agreement, and in accordance with the
terms of the indenture for ENTEX's 12-1/2% Senior Subordinated Notes due 2006,
ENTEX will call for redemption all of the Notes outstanding at a redemption
price equal to 112-1/2% of their principal amount plus accrued interest to the
date of redemption. The redemption of the Notes will be funded by Siemens and is
expected to take place at least 30 days, and no more than 60 days, after the
Measurement Date.
