ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Subsection (a) of Section 145 of the General Corporation Law of the State
of Delaware empowers a corporation to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action, suit or proceeding whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful.
 
     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by right of the corporation to
procure a judgment in its favor by reason of the fact that such person acted in
any of the capacities set forth above, against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification may be made in respect to any claim
issue or matter as to which such person shall have been adjudged to be liable to
the corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
     Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
such action, suit or proceeding referred to in subsections (a) and (b) of
Section 145 or in the defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith; that the indemnification provided for
by Section 145 shall not be deemed exclusive of any other rights which the
indemnified party may be entitled; that indemnification provided by
 
                                      II-1
<PAGE>   3
 
Section 145 shall, unless otherwise provided when authorized or ratified,
continue as to a person who has ceased to be a director, officer, employee or
agent and shall inure to the benefit of such person's heirs, executors and
administrators; and empowers the corporation to purchase and maintain insurance
on behalf of a director or officer of the corporation against any liability
asserted against him and incurred by him in any such capacity, or arising out of
his status as such, whether or not the corporation would have the power to
indemnify him against such liabilities under Section 145.
 
     Section 102(b)(7) of the General Corporation Law or the State of Delaware
provides that a certificate of incorporation may contain a provision eliminating
or limiting the personal liability of a director to the corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director,
provided that such provision shall not eliminate or limit the liability of the
director (i) for any breach of the director's duty of loyalty to the corporation
or its stockholders, (ii) for acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction
from which the director derived an improper personal benefit.
 
     Article Eleventh of the registrant's Charter provides that, to the fullest
extent permitted by the Delaware General Corporation Law as the same exists or
as it may hereafter be amended, no director of the registrant shall be
personally liable to the registrant or its stockholders for monetary damages for
breach of fiduciary duty as a director.
 
     Section 6.1 of the registrant's Bylaws further provides that the registrant
shall, to the maximum extent and in the manner permitted by the General
Corporation Law of Delaware, indemnify each of its directors and officers
against expenses (including attorneys' fees), judgments, fines, settlements, and
other amounts actually and reasonably incurred in connection with any
proceeding, arising by reason of the fact that such person is or was an agent of
the registrant.
 
     The registrant has entered into indemnification agreements with each of its
directors and executive officers.
 
     The registrant maintains officers' and directors' liability insurance.

ITEM 17. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act, that is incorporated by reference in this Registration Statement
shall be
 
                                      II-2
<PAGE>   4
 
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the Delaware General Corporation Law, the Charter or the
Bylaws of the registrant, or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the registrant of expenses incurred or
paid by a director, officer, or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of such issue.
 
     The undersigned registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this

Company and the stockholders of the Company named in Schedule II hereto (the
"Selling Stockholders") propose, subject to the terms and conditions stated

Selling Stockholders are concurrently entering into an agreement (the
"International Underwriting Agreement") providing for the sale by the Company
and the Selling Stockholders of up to a total of 690,000 shares of Stock (the
"International Shares"), including the overallotment option thereunder, through
arrangements with certain underwriters outside the United States (the

require, references hereinafter to the Shares shall include all the shares of
Stock which may be sold pursuant to either this Agreement or the International
Underwriting Agreement, and references herein to any prospectus whether in
preliminary or final form, and whether as amended or supplemented, shall

         delivery of the Shares to be sold by such Selling Stockholder
         hereunder and otherwise to act on behalf of such Selling Stockholder
         in connection with the transactions contemplated by this Agreement,
         the International Underwriting Agreement and the Custody Agreement;
         and

                 (ix)     The Shares represented by the certificates held in
         custody for such Selling Stockholder under the Custody Agreement are,
         as a result of the obligations of such Selling Stockholder under this
         Agreement, subject to the interests of the Underwriters hereunder and
         the International Underwriters under the International Underwriting
         Agreement to the extent of such obligations; the arrangements made by
         such Selling Stockholder for such custody, and the appointment by such
         Selling Stockholder of the Attorneys-in-Fact by the Power of Attorney,
         are to that extent irrevocable; the obligations of the Selling
         Stockholders hereunder shall not be terminated by operation of law,
         whether by the death or incapacity of any individual Selling
         Stockholder or, in the case of an estate or trust, by the death or
         incapacity of any executor or trustee or the termination of such
         estate or trust, or in the case of a partnership or corporation, by
         the dissolution of such partnership or corporation, or by the

         or any such executor or trustee should die or become incapacitated, or
         if any such estate or trust should be terminated, or if any such
         partnership or corporation should be dissolved, or if any other such
         event should occur, before the delivery of the Shares hereunder,
         certificates representing the Shares shall be delivered by or on
         behalf of the Selling Stockholders in accordance with the terms and
         conditions of this Agreement, of the International Underwriting
         Agreement and of the Custody Agreements; and actions taken by the
         Attorneys-in-Fact pursuant to the Powers of Attorney shall be as valid
         as if such death, incapacity, termination, dissolution or other event
         had not occurred, regardless of whether or not the Custodian, the
         Attorneys-in-Fact, or any of them, shall have received notice of such
         death, incapacity, termination, dissolution or other event.
   
         2.      Subject to the terms and conditions herein set forth, (a) the
Company and each of the Selling Stockholders agree, severally and not jointly, 
to sell to each of the Underwriters, and each of the Underwriters agrees, 
severally and not jointly, to purchase from the Company and each of the
Selling Stockholders, at a purchase price per share of $ 44.90, the number of
Firm Shares (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying the aggregate number of Firm Shares to be sold by the
Company and each of the Selling Stockholders as set forth opposite their
respective names in Schedule II hereto by a fraction, the numerator of which is
the aggregate number of Firm Shares to be purchased by such Underwriter as set
forth opposite the name of such Underwriter in Schedule I hereto and the
denominator of which is the aggregate number of Firm Shares to be purchased by
all of the Underwriters from the Company and all of the Selling Stockholders
hereunder and (b) in the event and to the extent that the Underwriters shall
exercise the election to purchase Optional Shares as provided below, the
Company agrees to sell to each of the Underwriters, and each of the
Underwriters agrees, severally and not jointly, to purchase from the Company,
at the purchase price per share set forth in clause (a) of this Section 2, that
portion of the number of Optional Shares as to which such election shall have
been exercised (to be adjusted by you so as to eliminate fractional shares)
determined by multiplying such number of Optional Shares by a fraction the
numerator of which is the maximum number of Optional Shares which such
Underwriter is entitled to purchase as set forth opposite the name of such
Underwriter in Schedule I hereto and the denominator of which is the maximum
number of Optional Shares that all of the Underwriters are entitled to purchase
hereunder.

         The Company hereby grants to the Underwriters the right to purchase at
their election up to 600,000 Optional Shares, at the purchase price per share
set forth in the paragraph above, for the sole purpose of covering
over-allotments in the sale of the Firm Shares.  Any such election to purchase
Optional Shares may be exercised only by written notice from you to the
Company, given within a period of 30 calendar days after the date of this
Agreement and setting forth the aggregate number of Optional Shares to be
purchased and the date on which such Optional Shares are to be delivered, as
determined by you but in no event earlier than the First Time of Delivery (as
defined in Section 4 hereof) or, unless you and the Company otherwise agree in
writing, earlier than two or later than ten business days after the date of
such notice.

         3.      Upon the authorization by you of the release of the Firm
Shares, the several Underwriters propose to offer the Firm Shares for sale upon
the terms and conditions set forth in the Prospectus.
   
         4.      (a)      The Shares to be purchased by each Underwriter
hereunder, in definitive form, and in such authorized denominations and
registered in such names as Goldman, Sachs & Co. may request upon at least
forty-eight hours' prior notice to the Company and the Selling Stockholders
shall be delivered by or on behalf of the Company and the Selling Stockholders
to Goldman, Sachs & Co., through the facilities of The Depository Trust Company
("DTC"), for the account of such Underwriter, against payment by or on behalf
of such Underwriter of the purchase price therefor by certified or official
bank check or checks, payable to the order of the Company and the Custodian, as
their interests may appear, in Federal (same day) funds or by wire transfer of
Federal (same day) funds to the account or accounts specified by the Company
and the Custodian.  The Company will cause the certificates representing the
Shares to be made available for checking and packaging at least twenty-four
hours prior to the Time of Delivery (as defined below) with respect thereto at
the office of DTC or its designated custodian (the "Designated Office").  The
time and date of such delivery and payment shall be, with respect to the Firm
Shares, 9:30 a.m., New York City time, on December 10, 1997, or on such other
time and date as Goldman, Sachs & Co. and the Company  may agree upon in

by Goldman, Sachs & Co. of the Underwriters' election to purchase such Optional
Shares, or such other time and date as Goldman, Sachs & Co. and the Company may
agree upon in writing.  Such time and date for delivery of the Firm Shares is
herein called the "First Time of Delivery", such time and date for delivery of
the Optional Shares, if not the First Time of Delivery, is herein called the
"Second Time of Delivery", and each such time and date for delivery is herein
called a "Time of Delivery".
    
                 (b)      The documents to be delivered at each Time of
Delivery by or on behalf of the parties hereto pursuant to Section 7 hereof,
including the cross-receipt for the Shares and any additional documents
requested by the Underwriters pursuant to Section 7(k) hereof, will be
delivered at the offices of the Company, 909 E. Las Colinas Blvd., 16th Floor,
Irving, Texas  75039 (the "Closing Location"), and the Shares will be delivered

at the Closing Location at 3:00 p.m., New York City time, on the New York
Business Day next preceding each Time of Delivery, at which meeting the final
drafts of the documents to be delivered pursuant to the preceding sentence will
be available for review by the parties hereto.  For the purposes of this
Section 4, "New York Business Day" shall mean each Monday, Tuesday, Wednesday,

         and its subsidiaries under a lease filed as an exhibit to a document
         incorporated by reference into the Prospectus are held by them under
         leases that are, as to the Company and its subsidiaries, valid,

         and do not interfere with the use made and proposed to be made of such
         property and buildings by the Company and its subsidiaries;

                 (vi)     To such counsel's knowledge, there are no legal or
         governmental proceedings pending or threatened to which the Company or

         result in a breach or violation of any of the terms or provisions of,
         or constitute a default under, any indenture, mortgage, deed of trust,
         loan agreement or other agreement or instrument which is filed as an
         Exhibit to the Registration Statement, or filed as an exhibit to a
         document incorporated by reference therein, or listed on an annex to
         such opinion provided by the Underwriters (in giving the opinion in
         this clause, such counsel may attach to such opinion a list of the
         foregoing), nor will such action result in any violation of the
         provisions of the Certificate of Incorporation or By-laws of the
         Company or any statute or any order, rule or regulation known to such
         counsel of any court or governmental agency or body having
         jurisdiction over the Company or any of its subsidiaries or any of
         their properties (other than the clearance of the underwriting
         arrangements with the NASD, Blue Sky or state securities law matters

                 (ix)     No consent, approval, authorization, order,
         registration or qualification of or with any such court or

         Shares or the consummation by the Company of the transactions
         contemplated by this Agreement and the International Underwriting
         Agreement, except the registration under the Act of the Shares, and
         such consents, approvals, authorizations, registrations or
         qualifications as may be required under state or foreign securities or

         Shares by the Underwriters and the International Underwriters;

                 (x)      To such counsel's knowledge, neither the Company nor
         any "significant subsidiary" (as defined in Regulation S-X) of the
         Company (together with each of Think Systems Corporation, Optimax
         Systems Corporation and i2 Technologies (Canada), Inc.) is in
         violation of its Certificate of Incorporation or By-laws;

<PAGE>   16



                 (xi)     Neither the Company nor any of its subsidiaries is in
         default in the performance or observance of any material obligation,
         agreement, covenant or condition contained in any indenture, mortgage,
         deed of trust, loan agreement, or lease or agreement or other
         instrument which is filed as an Exhibit to, or referred to in, the
         Registration Statement, or filed as an exhibit to, or referred to in,
         a document incorporated by reference therein (in giving the opinion in
         this clause, such counsel may attach to such opinion a list of the
         foregoing;

                 (xii)    The statements incorporated by reference into the
         Prospectus, insofar as they purport to constitute a summary of the
         terms of the Stock, are accurate, complete and fair in all material
         respects;

                 (xiii)   The Company is not an "investment company" or an
         entity "controlled" by an "investment company", as such terms are
         defined in the Investment Company Act;

                 (xiv)    The documents incorporated by reference in the
         Prospectus or any further amendment or supplement thereto made by the
         Company prior to such Time of Delivery (other than the financial
         statements and related schedules thereto, and other financial data
         included or incorporated by reference therein, as to which such
         counsel need express no opinion), when they became effective or were
         filed with the Commission, as the case may be, complied as to form in
         all material respects with the requirements of the Act or the Exchange
         Act as applicable, and the rules and regulations of the Commission
         thereunder; and although they do not assume any responsibility for the
         accuracy, completeness or fairness of such documents (except as
         provided in opinion (xii)), they have no reason to believe that any of
         such documents (other than the financial statements and related
         schedules thereto, and other financial data included or incorporated
         by reference therein, to which such counsel need express no opinion),
         when such documents became effective or were so filed, as the case may
         be, contained, in the case of a registration statement which became
         effective under the Act, an untrue statement of a material fact or
         omitted to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading, or, in the
         case of other documents which were filed under the Exchange Act with
         the Commission, an untrue statement of a material fact or omitted to
         state a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made
         when such documents were so filed, not misleading; and

                 (xv)     The Registration Statement and the Prospectus and any
         further amendments and supplements thereto made by the Company prior
         to such Time of Delivery (other than the financial statements and
         related schedules thereto, and other financial data included or
         incorporated by reference therein, as to which such counsel need
         express no opinion) comply as to form in all material respects with
         the requirements of the Act and the rules and regulations thereunder;
         although they do not assume any responsibility for the accuracy,
         completeness or fairness of the statements contained in the
         Registration Statement or the Prospectus, except for those referred to
         in the opinion in subsection (xii) of this Section 7(c), they have no
         reason to believe that, as of its effective date, the Registration
         Statement or any further amendment thereto made by the Company prior
         to such Time of Delivery (other than the financial statements and
         related schedules thereto, and other financial data included or
         incorporated by reference therein, as to which such counsel need
         express no opinion) contained an untrue statement of a material fact
         or omitted to state a material fact required to be stated therein or
         necessary to make the





                                      -16-

         statements therein not misleading or that, as of its date, the
         Prospectus or any further amendment or supplement thereto made by the
         Company prior to such Time of Delivery (other than the financial
         statements and related schedules thereto, and other financial data
         included or incorporated by reference therein, as to which such
         counsel need express no opinion) contained an untrue statement of a
         material fact or omitted to state a material fact necessary to make
         the statements therein, in the light of the circumstances under which
         they were made, not misleading or that, as of such Time of Delivery,
         either the Registration Statement or the Prospectus or any further
         amendment or supplement thereto made by the Company prior to such Time
         of Delivery (other than the financial statements and related schedules
         thereto, and other financial data included or incorporated by
         reference therein, as to which such counsel need express no opinion)
         contains an untrue statement of a material fact or omits to state a
         material fact necessary to make the statements therein, in the light
         of the circumstances under which they were made, not misleading; and
         such counsel does not know of any amendment to the Registration
         Statement required to be filed or of any contracts or other documents
         of a character required to be filed as an exhibit to the Registration
         Statement or required to be incorporated by reference into the
         Prospectus or required to be described in the Registration Statement
         or the Prospectus which are not filed or incorporated by reference or
         described as required.

         In rendering such opinion, such counsel may state that they express no
opinion as to the laws of any jurisdiction other than the federal securities
laws of the United States, the Delaware General Corporation Law, and the laws
of the State of Texas.  With respect to the opinions set forth in subparagraphs
(iv) and (x) above, to the extent that such opinions address questions of law
not involving the federal securities laws of the United States, the Delaware
General Corporation Law or the laws of the State of Texas, such counsel may
deliver opinions of local counsel as to such matters, provided that Brobeck,
Phleger & Harrison LLP shall state that they believe that you are justified in
relying upon such opinions.  In addition, in lieu of rendering the opinions set
forth in subparagraphs (v) and (xi) above, such counsel may deliver an opinion
of Robert C. Donohoo, Corporate Counsel to the Company as to such matters,
provided that Brobeck, Phleger & Harrison LLP shall state that they believe
that you are justified in relying upon such opinions.

                 (d)      Brobeck, Phleger & Harrison LLP, special counsel for
each of the Selling Stockholders, shall have furnished to you their written
opinion with respect to each of the Selling Stockholders (a draft of such
opinion is attached as Annex II(c) hereto), dated the First Time of Delivery,
in form and substance satisfactory to you, to the effect that:

                 (i)      A Power of Attorney and a Custody Agreement have been
         duly executed and delivered by such Selling Stockholder and constitute
         valid and binding agreements of such Selling Stockholder in accordance
         with their terms;

                 (ii)     This Agreement and the International Underwriting
         Agreement have been duly executed and delivered by or on behalf of
         such Selling Stockholder; and the sale of the Shares to be sold by
         such Selling Stockholder hereunder and thereunder and the compliance
         by such Selling Stockholder with all of the provisions of this
         Agreement and the International Underwriting Agreement, the Power of
         Attorney and the Custody Agreement and the consummation of the
         transactions herein and therein contemplated will not conflict with or
         result in a breach or violation of any terms or provisions of, or
         constitute a default under, any statute, or any material





                                      -17-
<PAGE>   18



         indenture, mortgage, deed of trust, loan agreement or other agreement
         or instrument known to such counsel to which such Selling Stockholder
         is a party or by which such Selling Stockholder is bound, or to which
         any of the property or assets of such Selling Stockholder is subject,
         nor will such action result in any violation of the provisions of the
         Certificate of Incorporation or By-laws of such Selling Stockholder if
         such Selling Stockholder is a corporation, the Partnership Agreement
         of such Selling Stockholder if such Selling Stockholder is a
         partnership or any order, rule or regulation known to such counsel of
         any court or governmental agency or body having jurisdiction over such
         Selling Stockholder or the property of such Selling Stockholder;

                 (iii)    To such counsel's knowledge, no consent, approval,
         authorization or order of any court or governmental agency or body is
         required for the consummation of the transactions contemplated by this
         Agreement and the International Underwriting Agreement in connection
         with the Shares to be sold by such Selling Stockholder hereunder or
         thereunder, except such as have been obtained under the Act and such
         as may be required under state or foreign securities or Blue Sky laws
         in connection with the purchase and distribution of such Shares by the
         Underwriters or the International Underwriters;

                 (iv)     Immediately prior to the consummation of the sale of
         Shares by each Selling Stockholder as contemplated by this Agreement
         and the International Underwriting Agreement, such Selling Stockholder
         was the sole registered owner of the Shares to be sold by such Selling
         Stockholder under this Agreement and the International Underwriting
         Agreement, and, to the knowledge of such counsel, there are no facts
         or circumstances that would lead such counsel to believe that, as of
         the First Time of Delivery, any Selling Stockholder is in breach of
         the warranties described in Section 8.108 of the Texas Uniform
         Commercial Code; and

                 (v)      The laws of the State of Texas govern the delivery of
         the certificates evidencing the Shares to be sold by the Selling
         Stockholders to the Underwriters and payment by the Underwriters of
         the purchase price for such Shares, and upon such delivery and payment
         the Underwriters will acquire such Shares free of all adverse claims
         (as such term is defined in Section 8.102 of the Texas Uniform
         Commercial Code), assuming that the Underwriters do not have notice of
         any adverse claim (as such term is defined in Section 8.102 of the
         Texas Uniform Commercial Code).

         In rendering such opinion, such counsel may state that they express no
opinion as to the laws of any jurisdiction other than the federal securities
laws of the United States, the Delaware General Corporation Law, and the laws
of the State of Texas.  With respect to the opinions set forth in subparagraphs
(i), (ii) and (iii) above, to the extent that such opinions address questions
of law not involving the federal securities laws of the United States, the
Delaware General Corporation Law or the laws of the State of Texas, such
counsel may deliver opinions of local counsel as to such matters, provided that
Brobeck, Phleger & Harrison LLP shall state that they believe that you are
justified in relying upon such opinions.   In addition, in rendering the
opinion in subparagraph (iv) such counsel may rely upon a certificate of such
Selling Stockholder in respect of matters of fact as to ownership of, and
liens, encumbrances, equities or claims on the Shares sold by such Selling
Stockholder, provided that such counsel shall state that they believe that both
you and they are justified in relying upon such certificate.

interference with its business from fire, explosion, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or court or
governmental action, order or decree, otherwise than as set forth or
contemplated in the Prospectus, and (ii) since the respective dates as of which
information is given in the Prospectus there shall not have been any change in
the capital stock,  stock options or long-term debt of the Company or any of
its subsidiaries or any change, or any development involving a prospective
change, in or affecting the general affairs, management, financial position,
stockholders' equity or results of operations of the Company and its
subsidiaries, otherwise than as set forth or contemplated in the Prospectus,
the effect of which, in any such case described in Clause (i) or (ii), is in
the judgment of the Representatives so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the
delivery of the Shares being delivered at such Time of Delivery on the terms
and in the manner contemplated in the Prospectus;

                 (g)      On or after the date hereof (i) no downgrading shall

on NASDAQ; (iii) a general moratorium on commercial banking activities declared

escalation of hostilities involving the United States or the declaration by the
United States of a national emergency or war, if the effect of any such event
specified in this Clause (iv) in the judgment of the Representatives makes it
impracticable or inadvisable to proceed with the public offering or the
delivery of the Shares being delivered at such Time of Delivery on the terms
and in the manner contemplated in the Prospectus;

                 (i)      The Shares to be sold by the Company and the Selling

Selling Stockholders"), jointly and severally, will indemnify and hold harmless
each Underwriter against any losses, claims, damages or liabilities, joint or 
several, to which such Underwriter may become subject, under the Act or 
otherwise, insofar as such losses, claims, damages or liabilities (or actions 
in respect thereof) arise out of or are based upon an untrue statement or 
alleged untrue statement of a material fact contained in any Preliminary 
Prospectus, the Registration Statement or the Prospectus, or any amendment or

upon an untrue statement or alleged untrue statement or omission or alleged 
omission made in any Preliminary Prospectus, the Registration Statement or the 
Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein; provided, further, that
the liability of each Management Selling Stockholder pursuant to this
subsection (a) shall not (i) exceed the product of the number of Shares sold by
such Management Selling Stockholder and the public offering price of the Shares
as set forth in the Prospectus or (ii) extend to any losses, claims, damages or
liabilities to which an Underwriter may become subject unless an Underwriter
shall have given notice of such losses, claims, damages or liabilities (or
actions in respect thereof) within two years from the date of this Agreement
and a claim related thereto shall have been made within three years from the
date of this Agreement.
    
         (b)     Each of the Selling Stockholders (other than the Management
Selling Stockholders) will indemnify and hold harmless each Underwriter against
any losses, claims, damages or liabilities, joint or several, to which such
Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated





                                      -20-

therein or necessary to make the statements therein not misleading, in each
case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement or the Prospectus or any
such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Selling Stockholder expressly for
use therein; and will reimburse each Underwriter for any legal or other
expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that such Selling Stockholder shall not be liable
in any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in any Preliminary Prospectus, the
Registration Statement or the Prospectus or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through Goldman, Sachs & Co.  expressly for use
therein; provided, further, that the liability of a Selling Stockholder
pursuant to this subsection (b) shall not exceed the product of the number of
Shares sold by such Selling Stockholder and the public offering price of the
Shares as set forth in the Prospectus.

         (c)     Each Underwriter will indemnify and hold harmless the Company
and each Selling Stockholder against any losses, claims, damages or liabilities
to which the Company or such Selling Stockholder may become subject, under the
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
or alleged untrue statement of a material fact contained in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through Goldman, Sachs & Co.
expressly for use therein; and will reimburse the Company and each Selling
Stockholder for any legal or other expenses reasonably incurred by the Company
or such Selling Stockholder in connection with investigating or defending any
such action or claim as such expenses are incurred.

         (d)     Promptly after receipt by an indemnified party under
subsection (a), (b) or (c) above of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party under such subsection, notify the indemnifying
party in writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection.  In case any such
action shall be brought against any indemnified party and it shall notify the
indemnifying party of the commencement thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (which shall not,
except with the consent of the indemnified party, be counsel to the
indemnifying party), and, after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such
subsection for any legal expenses of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party, in connection with
the defense thereof other than reasonable costs of investigation. No





                                      -21-

indemnifying party shall, without the written consent of the indemnified party,
effect the settlement or compromise of, or consent to the entry of any judgment
with respect to, any pending or threatened action or claim in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified party is an actual or potential party to such action or claim)
unless such settlement, compromise or judgment (i) includes an unconditional
release of the indemnified party from all liability arising out of such action
or claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of any indemnified party.

         (e)     If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a), (b) or (c) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities
(or actions in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Company and the Selling Stockholders on
the one hand and the Underwriters on the other from the offering of the Shares.
If, however, the allocation provided by the immediately preceding sentence is
not permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (d) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company and the Selling Stockholders on the one
hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations.  The relative benefits received by the Company and the Selling
Stockholders on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the offering of the
Shares purchased under this Agreement (before deducting expenses) received by
the Company and the Selling Stockholders bear to the total underwriting
discounts and commissions received by the Underwriters with respect to the
Shares purchased under this Agreement, in each case as set forth in the table
on the cover page of the Prospectus.  The relative fault shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the Selling
Stockholders on the one hand or the Underwriters on the other and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.  The Company, each of the Selling
Stockholders and the Underwriters agree that it would not be just and equitable
if contributions pursuant to this subsection (e) were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to above in this subsection (e).  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to
above in this subsection (e) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim.  Notwithstanding the
provisions of this subsection (e), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Shares underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission.  No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The





                                      -22-
<PAGE>   23



Underwriters' obligations in this subsection (e) to contribute are several in
proportion to their respective underwriting obligations and not joint.

                 (f) The obligations of the Company and the Selling
Stockholders under this Section 8 shall be in addition to any liability which
the Company and the respective Selling Stockholders may otherwise have and
shall extend, upon the same terms and conditions, to each person, if any, who
controls any Underwriter within the meaning of the Act; and the obligations of
the Underwriters under this Section 8 shall be in addition to any liability
which the respective Underwriters may otherwise have and shall extend, upon the
same terms and conditions, to each officer and director of the Company and to
each person, if any, who controls the Company or any Selling Stockholder within
the meaning of the Act.

         9.      (a)      If any Underwriter shall default in its obligation to
purchase the Shares which it has agreed to purchase hereunder at a Time of
Delivery, you may in your discretion arrange for you or another party or other
parties to purchase such Shares on the terms contained herein.  If within
thirty-six hours after such default by any Underwriter you do not arrange for
the purchase of such Shares, then the Company and the Selling Stockholders
shall be entitled to a further period of thirty-six hours within which to
procure another party or other parties satisfactory to you to purchase such
Shares on such terms.  In the event that, within the respective prescribed
periods, you notify the Company and the Selling Stockholders that you have so
arranged for the purchase of such Shares, or the Company and the Selling
Stockholders notify you that they have so arranged for the purchase of such
Shares, you or the Company and the Selling Stockholders shall have the right to
postpone such Time of Delivery for a period of not more than seven days, in
order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person
had originally been a party to this Agreement with respect to such Shares.

                 (b)      If, after giving effect to any arrangements for the
purchase of the Shares of a defaulting Underwriter or Underwriters by you and
the Company and the Selling Stockholders as provided in subsection (a) above,
the aggregate number of such Shares which remains unpurchased does not exceed
one-eleventh of the aggregate number of all of the Shares to be purchased at
such Time of Delivery, then the Company and the Selling Stockholders shall have
the right to require each non-defaulting Underwriter to purchase the number of
Shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of Shares which such
Underwriter agreed to purchase hereunder) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

                 (c)      If, after giving effect to any arrangements for the
purchase of the Shares of a defaulting Underwriter or Underwriters by you and
the Company and the Selling Stockholders as provided in subsection (a) above,
the aggregate number of such Shares which remains unpurchased exceeds
one-eleventh of the aggregate number of all of the Shares to be purchased at
such Time of Delivery, or if the Company and the Selling Stockholders shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the





                                      -23-
<PAGE>   24



obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of
any non-defaulting Underwriter or the Company or the Selling Stockholders,
except for the expenses to be borne by the Company and the Selling Stockholders
and the Underwriters as provided in Section 6 hereof and the indemnity and
contribution agreements in Section 8 hereof; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         10.     The respective indemnities, agreements, representations,
warranties and other statements of the Company, the Selling Stockholders and
the several Underwriters, as set forth in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement, shall remain in full
force and effect, regardless of any investigation (or any statement as to the
results thereof) made by or on behalf of any Underwriter or any controlling
person of any Underwriter, or the Company, or any of the Selling Stockholders,
or any officer or director or controlling person of the Company, or any
controlling person of any Selling Stockholder, and shall survive delivery of
and payment for the Shares.

         11.     If this Agreement shall be terminated pursuant to Section 9
hereof, neither the Company nor the Selling Stockholders shall then be under
any liability to any Underwriter except as provided in Sections 6 and 8 hereof;
but, if for any other reason any Shares are not delivered by or on behalf of
the Company and the Selling Stockholders as provided herein, the Company will
reimburse the Underwriters through you for all out-of-pocket expenses approved
in writing by you, including fees and disbursements of counsel, reasonably
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of the Shares not so delivered, but the Company and the Selling
Stockholders shall then be under no further liability to any Underwriter in
respect of the Shares not so delivered except as provided in Sections 6 and 8
hereof.  Without limiting the foregoing, if this Agreement shall be terminated
for any reason, the Underwriters shall have no liability to the Company or the
Selling Stockholders under the last sentence of Section 6 hereof.

         12.     In all dealings hereunder, you shall act on behalf of each of
the Underwriters, and the parties hereto shall be entitled to act and rely upon
any statement, request, notice or agreement on behalf of any Underwriter made
or given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives; and in all dealings with any Selling Stockholder hereunder,
you and the Company shall be entitled to act and rely upon any statement,
request, notice or agreement on behalf of such Selling Stockholder made or
given by any or all of the Attorneys-in-Fact for such Selling Stockholder.

         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex
or facsimile transmission to you as the representatives in care of Goldman,
Sachs & Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; if to any Selling Stockholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Stockholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of
the Company set forth in the Registration Statement, Attention: Secretary;
provided, however, that any notice to an Underwriter pursuant to Section 8(d)
hereof shall be delivered or sent by mail, telex or facsimile transmission to
such Underwriter at its address set forth in its Underwriters' Questionnaire or
telex constituting such Questionnaire, which address will be supplied to the
Company or the Selling Stockholders by you upon request.  Any such statements,
requests, notices or agreements shall take effect upon receipt thereof.

         13.     This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and the Selling Stockholders and, to
the extent provided in Sections 8 and 10 hereof, the officers and directors of
the Company and each person who controls the Company, any Selling Stockholder
or any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement.  No purchaser of any of the Shares from
any Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

         14.     Time shall be of the essence of this Agreement.  As used
herein, the term "business day" shall mean any day when the Commission's office
in Washington, D.C. is open for business.

         15.     This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

         16.     This Agreement may be executed by any one or more of the
parties hereto in any number of counterparts, each of which shall be deemed to
be an original, but all such counterparts shall together constitute one and the
same instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us eight (8) counterparts hereof, and upon the acceptance hereof
by you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement among each of the Underwriters, the
Company and each of the Selling Stockholders.  It is understood that your
acceptance of this letter on behalf of each of the Underwriters is pursuant to
the authority set forth in a form of Agreement among Underwriters (U.S.
Version), the form of which shall be submitted to the Company and the Selling
Stockholders for examination upon request, but without warranty on your part as
to the authority of the signers thereof.

         Pursuant to Section 7(d) of the Underwriting Agreement, the
accountants shall furnish letters to the Underwriters to the effect that:

                 (i)      They are independent certified public accountants
         with respect to the Company and its subsidiaries within the meaning of
         the Act and the applicable published rules and regulations thereunder;

                 (ii)     In their opinion, the financial statements and any
         supplementary financial information and schedules (and, if applicable,
         financial forecasts and/or pro forma financial information) examined
         by them and included or incorporated by reference in the Registration
         Statement or the Prospectus comply as to form in all material respects
         with the applicable accounting requirements of the Act or the Exchange
         Act, as applicable, and the related published rules and regulations
         thereunder; and, if applicable, they have made a review in accordance
         with standards established by the American Institute of Certified
         Public Accountants of the consolidated interim financial statements,
         selected financial data, pro forma financial information, financial
         forecasts and/or condensed financial statements derived from audited
         financial statements of the Company for the periods specified in such
         letter, as indicated in their reports thereon, copies of which have
         been separately furnished to the representatives of the Underwriters
         (the "Representatives");

                 (iii)    They have made a review in accordance with standards
         established by the American Institute of Certified Public Accountants
         of the unaudited condensed consolidated statements of income,
         consolidated balance sheets and consolidated statements of cash flows
         included in the Prospectus and/or incorporated by reference into the
         Prospectus as indicated in their reports thereon copies of which have
         been separately furnished to the Representatives; and on the basis of
         specified procedures including inquiries of officials of the Company
         who have responsibility for financial and accounting matters regarding
         whether the unaudited condensed consolidated financial statements
         referred to in paragraph (vi)(A)(i) below comply as to form in all
         material respects with the applicable accounting requirements of the
         Act and the Exchange Act and the related published rules and
         regulations, nothing came to their attention that caused them to
         believe that the unaudited condensed consolidated financial statements
         do not comply as to form in all material respects with the applicable
         accounting requirements of the Act and the Exchange Act and the
         related published rules and regulations;

                 (iv)     The unaudited selected financial information with
         respect to the consolidated results of operations and financial
         position of the Company for the five most recent fiscal years included
         in the Prospectus or incorporated by reference therein agrees with the
         corresponding amounts (after restatement where applicable) in the
         audited consolidated financial statements for such five fiscal years
         which were included or incorporated by reference in the Company's
         Annual Reports on Form 10-K for such fiscal years and in the Company's
         Current Reports on Form 8-K, as the case may be;

         under selected captions with the disclosure requirements of Regulation
         S-K and on the basis of limited procedures

         specified in such letter nothing came to their attention as a result
         of the foregoing procedures that caused them to believe that this
         information does not conform in all material respects with the
         disclosure requirements of Items 301, 302, 402 and 503(d),
         respectively, of Regulation S-K;

                 (vi)     On the basis of limited procedures, not constituting
         an examination in accordance with generally accepted auditing
         standards, consisting of a reading of the unaudited financial
         statements and other information referred to below, a reading of the
         latest available interim financial statements of the Company and its
         subsidiaries, inspection of the minute books of the Company and its
         subsidiaries since the date of the latest audited financial statements
         included or incorporated by reference in the Prospectus, inquiries of
         officials of the Company and its subsidiaries responsible for
         financial and accounting matters and such other inquiries and
         procedures as may be specified in such letter, nothing came to their
         attention that caused them to believe that:

                          (A)     (i) the unaudited condensed consolidated
                 statements of income, consolidated balance sheets and
                 consolidated statements of cash flows included in the
                 Prospectus and/or incorporated by reference in the Prospectus

                 applicable accounting requirements of the Exchange Act and the
                 related published rules and regulations, or (ii) any material
                 modifications should be made to the unaudited condensed
                 consolidated statements of income, consolidated balance sheets
                 and consolidated statements of cash flows included in the

                 them to be in conformity with generally accepted accounting
                 principles;

                          (B)     any other unaudited income statement data and
                 balance sheet items included in the Prospectus do not agree
                 with the corresponding items in the unaudited consolidated
                 financial statements from which such data and items were
                 derived, and any such unaudited data and items were not
                 determined on a basis substantially consistent with the basis
                 for the corresponding amounts in the audited consolidated
                 financial statements included or incorporated by reference in
                 the Company's Current Reports on Form 8-K for the most recent
                 fiscal year;

                          (C)     the unaudited financial statements which were
                 not included in the Prospectus but from which were derived the
                 unaudited condensed financial statements referred to in Clause
                 (A) and any unaudited income statement data and balance sheet
                 items included in the Prospectus and referred to in Clause (B)
                 were not determined on a basis substantially consistent with
                 the basis for the audited financial statements included or
                 incorporated by reference in the Company's Current Reports on
                 Form 8-K for the most recent fiscal year;

                          (D)     any unaudited pro forma consolidated
                 condensed financial statements included or incorporated by
                 reference in the Prospectus do not comply as to form in all
                 material respects with the applicable accounting requirements
                 of the Act and the published rules and regulations thereunder
                 or the pro forma adjustments have not been properly applied to
                 the historical amounts in the compilation of those statements;

                 are described in such letter; and

                          (F)     for the period from the date of the latest

Ladies and Gentlemen:

         i2 Technologies, Inc., a Delaware corporation (the "Company"),
proposes, subject to the terms and conditions stated herein, to issue and sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of 400,000 shares and, at the election of the Underwriters, up to 90,000
additional shares of Common Stock, par value $.00025 ("Stock") of the Company
and the stockholders of the Company named in Schedule II hereto (the "Selling
Stockholders") propose, subject to the terms and conditions stated herein, to
sell to the Underwriters an aggregate of 200,000 shares of Stock. The aggregate
of 600,000 shares to be sold by the Company and the Selling Stockholders is
herein called the "Firm Shares" and the aggregate of 90,000 additional shares
to be sold by the Company is herein called the "Optional Shares". The Firm
Shares and the Optional Shares which the Underwriters elect to purchase pursuant
to Section 2 hereof are herein collectively called, the "Shares"

         It is understood and agreed to by all parties that the Company the
Selling Stockholders are concurrently entering into an agreement, a copy of
which is attached hereto (the "U.S. Underwriting Agreement"), providing for the
sale by the Company and the Selling Stockholders of up to a total of 2,760,000
shares of Stock (the "U.S. Shares"), including the overallotment option
thereunder, through arrangements with certain underwriters in the United States
(the "U.S. Underwriters"), for whom Goldman, Sachs & Co., Deutsche Morgan
Grenfell, Inc., Hambrecht & Quist LLC and UBS Securities LLC are acting as
representatives. Anything herein or therein to the contrary notwithstanding,
the respective closings under this Agreement and the U.S. Underwriting
Agreement are hereby expressly made conditional on one another. The
Underwriters hereunder and the U.S. Underwriters are simultaneously entering
into an Agreement between U.S. and International Underwriting Syndicates (the
"Agreement between Syndicates")  which provides, among other things, for the
transfer of shares of Stock between the two syndicates and for consultation by
the Lead Managers hereunder with Goldman, Sachs 
    
<PAGE>   2

&  Co. prior to exercising the rights of the Underwriters under Section 7
hereof. Two forms of prospectus are to be used in connection with the offering
and sale of shares of Stock contemplated by the foregoing, one relating to the
Shares  hereunder and the other relating to the U.S. Shares. The latter form of
prospectus will be identical to the former except for certain substitute pages.
Except as used in Sections 2, 3, 4, 9 and 11 herein, and except as context may
otherwise require, references hereinafter to the Shares shall include all of
the shares of Stock which may be sold pursuant to either this Agreement or the
U.S. Underwriting Agreement, and references herein to any prospectus whether in
preliminary or final form, and whether as amended or supplemented, shall
include both the U.S. and the international versions thereof.

         In addition, this Agreement incorporates by reference certain
provisions from the U.S. Underwriting Agreement (including the related
definitions of terms, which are also used elsewhere herein) and, for purposes of
applying the same, references (whether in these precise words or their
equivalent) in the incorporated provisions to the "Underwriters" shall be to the
Underwriters hereunder, to the "Shares" shall be to the Shares hereunder as just
defined, to "this Agreement" (meaning therein the U.S. Underwriting Agreement)
shall be to this Agreement (except where this Agreement is already referred to
or as the context may otherwise require) and to the representatives of the
Underwriters or to Goldman, Sachs & Co. shall be to the addressees of this
Agreement and to Goldman Sachs International ("GSI"), and, in general, all such
provisions and defined terms shall be applied mutatis mutandis as if the
incorporated provisions were set forth in full herein having regard to their
context in this Agreement as opposed to the U.S. Underwriting Agreement.


         1.       The Company and each of the several Selling Stockholders 
hereby make to the Underwriters the same respective representations, warranties
and agreements as are set forth in Section 1 of the U.S. Underwriting
Agreement, which Section is incorporated herein by this reference.

   
         2.       Subject to the terms and conditions herein set forth, (a) the 
Company and each of the Selling Stockholders agree, severally and not jointly,
to sell to each of the Underwriters, and each of the Underwriters agrees,
severally and not jointly, to purchase from the Company and each of the Selling
Stockholders, at a purchase price per share of $44.90, the number of Firm
Shares (to be adjusted by you so as to eliminate fractional shares) determined
by multiplying the aggregate number of Firm Shares to be sold by the Company and
each of the Selling Stockholders as set forth opposite their respective names in
Schedule II hereto by a fraction, the numerator of which is the aggregate number
of Firm Shares to be purchased by such Underwriter as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is
the aggregate number of Firm Shares to be purchased by all the Underwriters from
the Company and all the Selling Stockholders hereunder and (b) in the event and
to the extent that the Underwriters shall exercise the election to purchase
Optional Shares as provided below, the Company agrees to sell to each of the
Underwriters, and each of the Underwriters agrees, severally and not jointly, to
purchase from the Company, at the purchase price per share set forth in clause
(a) of this Section 2, that portion of the number of Optional Shares as to which
such election shall have been exercised (to be adjusted by you so as to
eliminate fractional shares) determined by multiplying such number of Optional
Shares by a fraction the numerator of which is the maximum number of Optional
Shares which such Underwriter is entitled to purchase as set forth opposite the
name of such Underwriter in Schedule I hereto and the denominator of which is 
the maximum number of Optional Shares that all of the Underwriters are entitled 
to purchase hereunder.

         The Company hereby grants to the Underwriters the right to purchase at
their election up to 150,000 Optional Shares, at the purchase price per share
set forth in the paragraph above, for the sole purpose of covering
overallotments in the sale of the Firm Shares. Any such election to purchase
Optional Shares may be exercised only by written notice from you to the Company,
given within a period of 30 calendar days after the date of this Agreement and
setting forth the aggregate number of Optional Shares to be purchased and the
date on which such Optional Shares are to be delivered, as determined by you but
in no event earlier than the First Time of Delivery (as defined in Section 4
hereof) or, unless you and the Company otherwise agree in writing, earlier than
two or later than ten business days after the date of such notice.

         3. Upon the authorization by GSI of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus and in the forms of Agreement among
Underwriters (International Version) and Selling Agreements, which have been
previously submitted to the Company by you. Each Underwriter hereby makes to and
with the Company and the Selling Stockholders the representations and agreements
of such Underwriter as a member of the selling group contained in Sections 3(d)
and 3(e) of the form of Selling Agreements.

   
         4.       (a)  The Shares to be purchased by each Underwriter 
hereunder, in definitive form, and in such authorized denominations and
registered in such names as Goldman, Sachs & Co. may request upon at least
forty-eight hours' prior notice to the Company and the Selling Stockholders
shall be delivered by or on behalf of the Company and the Selling Stockholders
to Goldman, Sachs & Co., through the facilities of The Depository Trust Company
("DTC"), for the account of such Underwriter, against payment by or on behalf of
such Underwriter of the purchase price therefor by certified or official bank
check or checks, payable to the order of the Company and the Custodian, as their
interests may appear, in Federal (same day) funds or by wire transfer of Federal
(same day) funds to the account or accounts specified by the Company and the
Custodian. The Company will cause the certificates representing the Shares to be
made available for checking and packaging at least twenty-four hours prior to
the Time of Delivery (as defined below) with respect thereto at the office of
DTC or its designated custodian (the "Designated Office"). The time and date of
such delivery and payment shall be, with respect to the Firm Shares, 9:30 a.m.,
New York City time, on December 10, 1997 on such other time and date as
Goldman, Sachs & Co. and, the Company may agree upon in writing, and, with
respect to the Optional Shares, 9:30 a.m., New York City time, on the date
specified by Goldman, Sachs & Co. in the written notice given by Goldman, Sachs
& Co. of the Underwriters' election to purchase such Optional Shares, or such
other time and date as Goldman, Sachs & Co. and, the Company may agree upon in
writing. Such time and date for delivery of the Firm Shares is herein called the
"First Time of Delivery", such time and date for delivery of the Firm Optional
Shares, if not the First Time of Delivery, is herein called the "Second Time of
Delivery", and each such time and date for delivery is herein called a "Time of
Delivery".
    
                  (b)  The documents to be delivered at each Time of Delivery by
or on behalf of the parties hereto pursuant to Section 7 of the U.S.
Underwriting Agreement, including the cross-receipt for the Shares and any
additional documents requested by the Underwriters pursuant to Section 7(k) of
the U.S. Underwriting Agreement, and the check or checks specified in subsection
(a) above, will be delivered at the offices of the Company, 909 E. Las Colinas
Blvd., 16th Floor, Irving, Texas 75039 (the "Closing Location"), and the Shares
will be delivered at the Designated Office, all at each Time of Delivery. A
meeting will be held at the Closing Location at two o'clock p.m., New York City
time, on the New York Business Day next preceding each Time of Delivery, at
which meeting the final drafts of

                                      -3-

<PAGE>   4
the of the documents to be delivered pursuant to the preceding sentence will
be available for review by the parties hereto. For the purposes of this Section
4, "New York Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday
and Friday which is not a day on which banking institutions in New York are
generally authorized or obligated by law or executive order to close.

         5. The Company hereby makes with the Underwriters the same agreements
as are set forth in Section 5 of the U.S. Underwriting Agreement, which Section
is incorporated herein by this reference.

   
         6. The Company, each of the Selling Stockholders, and the Underwriters
hereby agree with respect to certain expenses on the same terms as are set forth
in Section 6 of the U.S. Underwriting Agreement, which Section is incorporated
herein by this reference; provided that the last sentence of such Section 6
shall be as follows: "In addition, (A) the Underwriters will reimburse the
Company an aggregate of $35,500.00 and pay to the Custodian for the benefit of
the Selling Stockholders an aggregate of $17,750.00, and (B) in the event and to
the extent that the Underwriters shall exercise the election to purchase
Optional Shares as provided in Section 2, the Underwriters will reimburse the
Company an aggregate of $7,987.50 multiplied by a fraction the numerator of
which is the aggregate number of Optional Shares which the Underwriters so elect
to purchase and the denominator of which is 90,000.
    

         7. Subject to the provisions of the Agreement between Syndicates, the
obligations of the Underwriters hereunder shall be subject, in their discretion,
at each Time of Delivery to the condition that all representations and
warranties and other statements of the Company, and the Selling Stockholders
herein are, at and as of such Time of Delivery, true and correct, the condition
that the Company and the Selling Stockholders shall have performed all of their
respective obligations hereunder theretofore to be performed, and additional
conditions identical to those set forth in Section 7 of the U.S. Underwriting
Agreement, which Section is incorporated herein by this reference.

   
         8. (a) The Company and each of Sanjiv S. Sidhu, Kanna N. Sharma, The
K-B Sharma Limited Partnership, Sidhu-Singh Family Investments, Ltd., Sandeep
R.  Tungare and Gregory A. Brady (collectively, the "Management Selling 
Stockholders"), jointly and severally, will indemnify and hold harmless each 
Underwriter against any losses, claims, damages or liabilities, joint or 
several, to which such Underwriter may become subject, under the Act or 
otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon an untrue statement or
alleged untrue statement of a material fact contained in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse
each Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that the Company and
the Management Selling Stockholders shall not be liable in any such case to the
extent that any such loss, claim, damage or liability arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in any Preliminary Prospectus, the Registration Statement or the
Prospectus or any such amendment or supplement in reliance upon and in
conformity with written  information furnished to the Company by any
Underwriter through GSI expressly for use therein; provided, further, that the
liability of each Management Selling Stockholder pursuant to this subsection
(a) shall not (i) exceed the product of the number of Shares sold by such
Management Selling Stockholder and the public offering price of the Shares as
set forth in the Prospectus or (ii) extend to any losses, claims, damages or
liabilities to which an Underwriter may become subject unless an Underwriter
    

                                       -4-

<PAGE>   5
shall have given notice of such losses, claims, damages or liabilities (or
actions in respect thereof) within two years from the date of this Agreement and
a claim related thereto shall have been made within three years from the date of
this Agreement.

                  (b) Each of the Selling Stockholders (other than the
Management Selling Stockholders), jointly and severally, will indemnify and hold
harmless each Underwriter against any losses, claims, damages or liabilities,
joint or several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by such
Selling Stockholder expressly for use therein; and will reimburse each
Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that such Selling
Stockholder shall not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
any Preliminary Prospectus, the Registration Statement or the Prospectus or any
such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through GSI expressly
for use therein; provided, further, that the liability of a Selling Stockholder
pursuant to this subsection (b) shall not exceed the product of the number of
Shares sold by such Selling Stockholder and the initial public offering price of
the Shares as set forth in the Prospectus.

                  (c) Each Underwriter will indemnify and hold harmless the
Company and each Selling Stockholder against any losses, claims, damages or
liabilities to which the Company or such Selling Stockholder may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through GSI expressly for use
therein; and will reimburse the Company and each Selling Stockholder for any
legal or other expenses reasonably incurred by the Company or such Selling
Stockholder in connection with investigating or defending any such action or
claim as such expenses are incurred.

                  (d) Promptly after receipt by an indemnified party under
subsection (a), (b) or (c) above of notice of the commencement of any action,
such indemnified party shall, if a claim in respect thereof is to be made
against an indemnifying party under such subsection, notify the indemnifying
party in writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not

                                       -5-

<PAGE>   6
relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

                  (e) If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
subsection (a), (b) or (c) above in respect of any losses, claims, damages or
liabilities (or actions in respect thereof) referred to therein, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages or liabilities (or
actions in respect thereof) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Selling Stockholders on the
one hand and the Underwriters on the other from the offering of the Shares. If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law or if the indemnified party failed to give the
notice required under subsection (d) above, then each indemnifying party shall
contribute to such amount paid or payable by such indemnified party in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company and the Selling Stockholders on the one hand
and the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by the Company and the Selling Stockholders on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Shares purchased
under this Agreement (before deducting expenses) received by the Company and the
Selling Stockholders bear to the total underwriting discounts and commissions
received by the Underwriters with respect to the Shares purchased under this
Agreement, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Selling Stockholders on the one hand or the
Underwriters on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, each of the Selling Stockholders and the Underwriters agree that it
would not be just and equitable if contributions pursuant to this subsection (e)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to above in this
subsection (e). The amount paid or payable by an indemnified party as a result
of the losses, claims, damages or liabilities (or actions in respect thereof)
referred to above in this subsection (e) shall 


                                       -6-

<PAGE>   7

be deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (e), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Shares underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this subsection
(e) to contribute are several in proportion to their respective underwriting
obligations and not joint.

                  (f) The obligations of the Company and the Selling
Stockholders under this Section 8 shall be in addition to any liability which
the Company and the respective Selling Stockholders may otherwise have and shall
extend, upon the same terms and conditions, to each person, if any, who controls
any Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company and to each
person, if any, who controls the Company or any Selling Stockholder within the
meaning of the Act.

               9. (a) If any Underwriter shall default in its obligation to 
purchase the Shares which it has agreed to purchase hereunder at a Time of
Delivery, you may in your discretion arrange for you or another party or other
parties to purchase such Shares on the terms contained herein. If within
thirty-six hours after such default by any Underwriter you do not arrange for
the purchase of such Shares, then the Company and the Selling Stockholders
shall be entitled to a further period of thirty-six hours within which to
procure another party or other parties satisfactory to you to purchase such
Shares on such terms. In the event that, within the respective prescribed
periods, you notify the Company and the Selling Stockholders that you have so
arranged for the purchase of such Shares, or the Company and the Selling
Stockholders notify you that they have so arranged for the purchase of such
Shares, you or the Company and the Selling Stockholders shall have the right to
postpone such Time of Delivery for a period of not more than seven days, in
order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person
had originally been a party to this Agreement with respect to such Shares.

                  (b) If, after giving effect to any arrangements for the
purchase of the Shares of a defaulting Underwriter or Underwriters by you and
the Company and the Selling Stockholders as provided in subsection (a) above,
the aggregate number of such Shares which remains unpurchased does not exceed
one-eleventh of the aggregate number of all the Shares to be purchased at such
Time of Delivery, then the Company and the Selling Stockholders shall have the
right to require each non-defaulting Underwriter to purchase the number of
shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of Shares which such
Underwriter agreed to purchase hereunder) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.


                                      -7-

<PAGE>   8

                  (c) If, after giving effect to any arrangements for the
purchase of the Shares of a defaulting Underwriter or Underwriters by you and
the Company and the Selling Stockholders as provided in subsection (a) above,
the aggregate number of such Shares which remains unpurchased exceeds
one-eleventh of the aggregate number of all the Shares to be purchased at such
Time of Delivery, or if the Company and the Selling Stockholders shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company or the Selling Stockholders, except
for the expenses to be borne by the Company and the Selling Stockholders and the
Underwriters as provided in Section 6 hereof and the indemnity and contribution
agreements in Section 8 hereof; but nothing herein shall relieve a defaulting
Underwriter from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company or any of the Selling Stockholders, or any officer
or director or controlling person of the Company or any controlling person of
any Selling Stockholders, and shall survive delivery of and payment for the
Shares.

         11. If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Section 6 and Section 8
hereof; but, if for any other reason, any Shares are not delivered by or on
behalf of the Company and the Selling Stockholders as provided herein, the
Company will reimburse the Underwriters through GSI for all out-of-pocket
expenses approved in writing by GSI, including fees and disbursements of
counsel, reasonably incurred by the Underwriters in making preparations for the
purchase, sale and delivery of the Shares not so delivered, but the Company and
the Selling Stockholders shall then be under no further liability to any
Underwriter in respect of the Shares not so delivered except as provided in
Sections 6 and 8 hereof. Without limiting the foregoing, if this Agreement shall
be terminated for any reason, the Underwriters shall have no liability to the
Company or the Selling Stockholders under the last sentence of Section 6 hereof.

         12. In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by GSI on behalf of you as the representatives of the
Underwriters; and in all dealings with any Selling Stockholder hereunder, you
and the Company shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of such Selling Stockholder made or given by any
or all of the Attorneys-in-Fact for such Selling Stockholder.
                                          
         All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the Underwriters in care of GSI, Peterborough Court,
133 Fleet Street, London EC4A 2BB, England, Attention: Equity Capital Markets,
Telex No. 94012165, facsimile transmission No. (071) 774-1550; if to any Selling
Stockholder shall be delivered or sent by mail, telex or facsimile transmission
to counsel for such Selling Stockholder at its address set forth in Schedule II
hereto; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the
Registration Statement,

                                       -8-

Attention: Secretary; provided, however, that any notice to an Underwriter
pursuant to Section 8(d) hereof shall be delivered or sent by mail, telex or
facsimile transmission to such Underwriter at its address set forth in its
Underwriters' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company or the Selling Stockholders by GSI upon
request. Any such statements, requests, notices or agreements shall take effect
upon receipt thereof.

         13. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and the Selling Stockholders and, to
the extent provided in Sections 8 and 10 hereof, the officers and directors of
the Company and each person who controls the Company, any Selling Stockholder or
any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. No purchaser of any of the Shares from any
Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

         14. Time shall be of the essence of this Agreement.

         15. This Agreement shall be governed by and construed in accordance
with the laws of the State of New York, United States of America.

         16. This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

         If the foregoing is in accordance with your understanding, please sign
and return to us eight (8) counterparts hereof, and upon the acceptance hereof
by you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement among each of the Underwriters, the
Company and each of the Selling Stockholders. It is understood that your
acceptance of this letter on behalf of each of the Underwriters is pursuant to
the authority set forth in a form of Agreement among Underwriters (International
Version), the form of which shall be furnished to the Company and the Selling
Stockholders for examination upon request, but without warranty on your part as
to the authority of the signers thereof.

         Any person executing and delivering this Agreement as Attorney-in-Fact
for a Selling Stockholder represents by so doing that he has been duly appointed
as Attorney-in-Fact by such Selling Stockholder pursuant to a validly existing
and binding Power of Attorney which authorizes such Attorney-in-Fact to take
such action.
