in relying in good faith upon any written certification, notice, direction,

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;

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'

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

     TAX ESCROW AGREEMENT, dated as of ________, 2000, among Siemens
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
assume and perform the duties of,

<PAGE>

escrow agent under and pursuant to this Agreement. The Tax Escrow Agent
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-
<PAGE>

Certificate not later than the second business day next following receipt
thereof, together with a copy of such Resolution Certificate.

     For purposes of this Agreement, the term "Release Date" shall mean the
first to occur of (i) the date the Company receives a refund of all or any
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
Escrow Agent shall pay over to Siemens from the Tax Escrow Fund, by wire

designation, a percentage of the taxable earnings sufficient to pay any
incremental income Taxes imposed on Siemens as a result of such taxable
earnings, as determined by Siemens, subject to the consent of the Stockholders'
Representative, which consent shall not be unreasonably withheld.

     (b) Expense Release. To the extent that (i) Siemens incurs any costs or
expenses in connection with any action, proceeding or claim relating solely to
the Tax Matters, Siemens shall notify the Stockholders' Representative and the

other costs and expenses incurred by the Stockholders' Representative in his
capacity as such in connection with the transactions contemplated by the Merger
Agreement and the Escrow Agreement, exceed the Stockholders' Representative
Expense Amount actually paid to the Stockholders' Representative pursuant to the
Merger Agreement, the Stockholders' Representative shall notify Siemens and the
Tax Escrow Agent and upon receipt of such written notice executed by the
Stockholders' Representative, the Tax Escrow Agent shall pay over to the
Stockholders' Representative from the Tax Escrow Fund, by wire transfer of
immediately available funds to a bank account of the Stockholders'
Representative's designation, the amount set forth in such notice; provided,
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

pursuant to the Merger Agreement and (y) amounts released to the Stockholders'

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

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.

     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.

Private Letter Ruling 8640021 (July 1, 1986), Siemens and the Stockholders'

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.

day" shall mean a day other than Saturday, Sunday or any day on which banks
