     7.  The obligations of the Purchasers hereunder shall be subject, in their

               (iv) To such counsel's knowledge and other than as set forth in
          the Offering Circular, there are no legal or governmental proceedings
          pending to which the Company is a party or of which any property of

          Company, would individually or in the aggregate have a material
          adverse effect on the current or future consolidated financial
          position, stockholders' equity or results of operations of the

          they to be completed on or prior to the date of such opinion and
          assuming the absence of any applicable cure period, waiting period or
          other similar provision, do not conflict with or result in a breach or
          violation of any of the terms or provisions of, or constitute a

          agreement exhibit on Form 10-Q or any other Exchange Act Report
          (provided that in determining which documents would be required to be
          so filed, such counsel may rely on an officer's certificate that
          specifies agreements that the Company has entered into since March 31,
          1998) nor does such action result in any violation of the provisions
          of the Certificate of Incorporation or Bylaws 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

                                      -14-
<PAGE>
 
               (ix) No consent, approval, authorization, order, registration or
          qualification of or with any court or governmental agency or body is
          required for the issue and sale of the Securities or the consummation
          by the Company of the transactions contemplated by this Agreement, the
          Indenture, the Escrow Agreement or the Registration Rights Agreement,
          except (A) such consents, approvals, authorizations, orders,
          registrations or qualifications as may be required under state
          securities or Blue Sky laws in connection with the purchase and
          distribution of the Securities by the Purchasers (as to which such
          counsel renders no opinion) or (B) such consents, approvals,
          authorizations, orders, registrations or qualifications as are
          referenced in the Offering Circular;

               (x) The Company is not in violation of its Certificate of
          Incorporation or Bylaws or, to such counsel's knowledge, in default in
          the performance or observance of any material obligation, agreement,
          covenant or condition contained in any Material Agreement;

               (xi) The statements set forth in the Offering Circular insofar as
          they purport to constitute a summary of the terms of the Securities,
          the Indenture, the Escrow Agreement and the Registration Rights
          Agreement, and under the captions "Certain United States Federal
          Income Tax Considerations" and "Underwriting," insofar as they purport
          to describe the provisions of the laws and documents referred to
          therein, are accurate and complete in all material respects;

               (xii) The Exchange Act Reports (other than the financial
          statements and related notes and schedules (and financial data)
          therein, as to which such counsel need express no opinion), when they
          were filed with the Commission, complied as to form in all material
          respects with the requirements of the Exchange Act, and the rules and
          regulations of the Commission promulgated thereunder;

               (xiii) No registration of the Securities under the Securities
          Act, and no qualification of an indenture under the Trust Indenture
          Act of 1939 with respect thereto, is required for the offer and sale
          to, and initial resale of the Securities by, the Purchasers in the
          manner contemplated by this Agreement;

               (xiv) The Company is not an "investment company," as such term is
          defined in the Investment Company Act;

               (xv) The Escrow Agreement has been duly and validly authorized,
          executed and delivered by the Company and the Escrow Agreement is the
          legally valid and binding obligation of the Company,

                                      -15-
<PAGE>
 
          enforceable against it in accordance with its terms, except as the
          enforceability thereof may be limited by customary assumptions and
          exceptions. Once the Escrow Account has been established as provided
          in the Escrow Agreement, the pledge and security interest in the
          Escrow Account and the Pledged Securities held in the Escrow Account
          (assuming such Pledged Securities constitute securities entitlements
          and are carried in such Escrow Account (as to which assumption such
          counsel need not express an opinion)) created by the Company under the
          Escrow Agreement in favor of the Trustee, for the benefit of the
          holders of the Securities, will constitute a perfected security
          interest which will be prior to any other security interest in such
          account or covering such securities entitlement, the priority of which
          is governed by the Uniform Commercial Code as in effect in the State
          of New York on the date hereof.

          In addition, such counsel shall state that, although they are not
          passing upon and do not assume any responsibility for, nor have they
          independently verified, the accuracy, completeness or fairness of the
          statements contained in the Preliminary Offering Circular and the
          Offering Circular, except for and to the extent of those referred to
          in the opinion in subsection (xi) of this Section 7(b), they have
          participated in certain conferences with officers and other employees
          of the Company, representatives of the Company's independent certified
          public accountants and representatives of the Purchasers with respect
          to the preparation of the Preliminary Offering Circular and the
          Offering Circular, and no facts have come to the attention of
          attorneys devoting attention to the representation of the Company in
          its preparation of the Preliminary Offering Circular and the Offering
          Circular that have caused them to believe that, as of their respective
          dates and as of the Time of Delivery, the Preliminary Offering
          Circular and the Offering Circular or any further amendments thereto
          made by the Company prior to such Time of Delivery (other than the
          financial statements and related notes, related schedules and
          financial data included 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 statements therein, in light of the
          circumstances under which they were made, not misleading. Further,
          such counsel shall state that, although they are not passing upon and
          do not assume any responsibility for, nor have they independently
          verified, the accuracy, completeness or fairness of the statements
          contained in the Exchange Act Reports, they have participated in
          certain conferences with officers and other employees of the Company,
          and representatives of the Company's independent certified public
          accountants with respect to the preparation of the respective Exchange
          Act Reports, and no facts have come to the attention of attorneys
          devoting attention to the representation of the Company in its
          preparation of the respective Exchange Act Reports that have caused
          them to believe that as of the dates on which the 

                                      -16-
<PAGE>
 
          respective Exchange Act Reports were filed with the Commission, the
          Exchange Act Reports (other than the financial statements and related
          notes, related schedules and financial data included therein, as to
          which such counsel need express no opinion) contained an untrue
          statement of material fact or omitted to state a material fact
          required to be stated therein or necessary to make the statements
          therein, in light of the circumstances under which they were made when
          such documents were so filed, not misleading.

          (c) On the date of the Offering Circular prior to the execution of
     this Agreement and also at the Time of Delivery, KPMG Peat Marwick LLP
     shall have furnished to you a letter or letters, dated the respective dates
     of delivery thereof, in form and substance satisfactory to you, to the
     effect set forth in Annex II hereto;

          (d) (i) The Company shall not have sustained since the date of the
     latest audited financial statements included in the Offering Circular any
     loss or 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 Offering Circular, and (ii) since the respective
     dates as of which information is given in the Offering Circular there shall
     not have been any change in the capital stock 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 Offering Circular, the effect of which, in any such
     case described in Clause (i) or (ii), is in the judgment of the Purchasers
     so material and adverse as to make it impracticable or inadvisable to
     proceed with the public offering or the delivery of the Securities on the
     terms and in the manner contemplated in this Agreement and in the Offering
     Circular;

          (e) On or after the date hereof (i) no downgrading shall have occurred
     in the rating accorded the Company's debt securities by any "nationally
     recognized statistical rating organization", as that term is defined by the
     Commission for purposes of Rule 436(g)(2) under the Securities Act, and
     (ii) no such organization shall have publicly announced that it has under
     surveillance or review, with possible negative implications, its rating of
     any of the Company's debt securities;

          (f) On or after the date hereof there shall not have occurred any of
     the following: (i) a suspension or material limitation in trading in
     securities generally on the New York Stock Exchange; or on NASDAQ; (ii) a
     suspension or material limitation in trading in the Company's securities on
     NASDAQ; (iii) a general moratorium on commercial banking activities
     declared by either Federal or New York or California State authorities;
     (iv) the outbreak or escalation of hostilities involving the United States
     or the declaration by the United States of a national emergency or war, if
     the 

                                      -17-
<PAGE>
 
     effect of any such event specified in this Clause (iv) in the judgment of
     the Purchasers makes it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Securities on the terms and in the
     manner contemplated in the Offering Circular; or (v) the occurrence of any
     material adverse change in the existing financial, political or economic
     conditions in the United States or elsewhere which, in the judgment of the
     Purchasers, would materially and adversely affect the financial markets or
     markets for the Securities or other debt securities;

          (g)  The Securities have been designated for trading on PORTAL;

          (h)  The Company shall have furnished to you executed copies of the
     Indenture, the Escrow Agreement and the Registration Rights Agreement; and

          (i) The Company shall have furnished or caused to be furnished to you
     at the Time of Delivery certificates of officers of the Company
     satisfactory to you as to the accuracy of the representations and
     warranties of the Company herein at and as of such Time of Delivery, as to
     the performance by the Company of all of its obligations hereunder to be
     performed at or prior to such Time of Delivery, as to the matters set forth
     in subsections (a) and (e) of this Section and as to such other matters as
     you may reasonably request.

     8.   (a)   The Company will indemnify and hold harmless each Purchaser
against any losses, claims, damages or liabilities, joint or several, to which
such Purchaser may become subject, under the Securities 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 Offering Circular or
the Offering Circular, 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 necessary to make the statements therein not misleading, and will reimburse
each Purchaser for any legal or other expenses reasonably incurred by such
Purchaser in connection with investigating or defending any such action or claim
as such expenses are incurred; provided, however, that the Company 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 Offering
Circular or the Offering Circular or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the
Company by any Purchaser through Goldman, Sachs & Co. expressly for use therein.

          (b) Each Purchaser will indemnify and hold harmless the Company
     against any losses, claims, damages or liabilities to which the Company may
     become subject, under the Securities 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 

                                      -18-
<PAGE>
 
     statement or alleged untrue statement of a material fact contained in any
     Preliminary Offering Circular or the Offering Circular, 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 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 Offering Circular
     or the Offering Circular or any such amendment or supplement in reliance
     upon and in conformity with written information furnished to the Company by
     such Purchaser through Goldman, Sachs & Co. expressly for use therein; and
     will reimburse the Company for any legal or other expenses reasonably
     incurred by the Company in connection with investigating or defending any
     such action or claim as such expenses are incurred.

          (c) Promptly after receipt by an indemnified party under subsection
     (a) or (b) above of notice of the commencement of any action, such
     indemnified party shall, if a claim in respect thereof is to be made
     against the 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 (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.

          (d) If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsection (a) or (b) above in respect of any losses, claims, damages or
     liabilities (or actions in respect thereof) 

                                      -19-
<PAGE>
 
     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 on the one hand and the Purchasers on the other from the
     offering of the Securities. 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 (c)
     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 on the one hand and the Purchasers 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 on the one hand and the Purchasers on the other shall be deemed to
     be in the same proportion as the total net proceeds from the offering
     (before deducting expenses) received by the Company bear to the total
     underwriting discounts and commissions received by the Purchasers, in each
     case as set forth in the Offering Circular. 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 on the one hand or the Purchasers on the other and the parties'
     relative intent, knowledge, access to information and opportunity to
     correct or prevent such statement or omission. The Company and the
     Purchasers agree that it would not be just and equitable if contribution
     pursuant to this subsection (d) were determined by pro rata allocation
     (even if the Purchasers 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 (d). 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 (d) 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 (d), no Purchaser shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Securities underwritten by it and distributed to investors were
     offered to investors exceeds the amount of any damages which such Purchaser
     has otherwise been required to pay by reason of such untrue or alleged
     untrue statement or omission or alleged omission. The Purchasers'
     obligations in this subsection (d) to contribute are several in proportion
     to their respective underwriting obligations and not joint.

          (e) The obligations of the Company under this Section 8 shall be in
     addition to any liability which the Company may otherwise have and shall
     extend, upon the same terms and conditions, to each person, if any, who
     controls any Purchaser within 

                                      -20-
<PAGE>
 
     the meaning of the Securities Act; and the obligations of the Purchasers
     under this Section 8 shall be in addition to any liability which the
     respective Purchasers 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 within the meaning of the
     Securities Act.

     9.   (a)  If any Purchaser shall default in its obligation to purchase the
Securities which it has agreed to purchase hereunder, you may in your discretion
arrange for you or another party or other parties to purchase such Securities on
the terms contained herein.  If within thirty-six hours after such default by
any Purchaser you do not arrange for the purchase of such Securities, then the
Company 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
Securities on such terms.  In the event that, within the respective prescribed
periods, you notify the Company that you have so arranged for the purchase of
such Securities, or the Company notifies you that it has so arranged for the
purchase of such Securities, you or the Company shall have the right to postpone
the 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 Offering Circular,
or in any other documents or arrangements, and the Company agrees to prepare
promptly any amendments to the Offering Circular which in your opinion may
thereby be made necessary.  The term "Purchaser" 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
Securities.

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

          (c) If, after giving effect to any arrangements for the purchase of
     the Securities of a defaulting Purchaser or Purchasers by you and the
     Company as provided in subsection (a) above, the aggregate principal amount
     of Securities which remains unpurchased exceeds one-eleventh of the
     aggregate principal amount of all the Securities, or if the Company shall
     not exercise the right described in subsection (b) above to require non-
     defaulting Purchasers to purchase Securities of a defaulting Purchaser or
     Purchasers, then this Agreement shall thereupon terminate, 

                                      -21-
<PAGE>
 
     without liability on the part of any non-defaulting Purchaser or the
     Company, except for the expenses to be borne by the Company and the
     Purchasers as provided in Section 6 hereof and the indemnity and
     contribution agreements in Section 8 hereof; but nothing herein shall
     relieve a defaulting Purchaser from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Purchasers, 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 Purchaser or any controlling person of any Purchaser, or the Company, or
any officer or director or controlling person of the Company, and shall survive
delivery of and payment for the Securities.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
the Company shall not then be under any liability to any Purchaser except as
provided in Sections 6 and 8 hereof; but, if for any other reason, the
Securities are not delivered by or on behalf of the Company as provided herein,
the Company will reimburse the Purchasers through you for all out-of-pocket
expenses approved in writing by you, including fees and disbursements of
counsel, reasonably incurred by the Purchasers in making preparations for the
purchase, sale and delivery of the Securities, but the Company shall then be
under no further liability to any Purchaser except as provided in Sections 6 and
8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Purchasers, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Purchaser made or given
by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Purchasers shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 32 Old Slip, 9th Floor, New York, New York 10004, Attention: Registration
Department; 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 Offering
Circular, Attention: Secretary; provided, however, that any notice to a
Purchaser pursuant to Section 8(c) hereof shall be delivered or sent by mail,
telex or facsimile transmission to such Purchaser at its address set forth in
its Purchasers' Questionnaire, or telex constituting such Questionnaire, which
address will be supplied to the Company 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 Purchasers, the Company 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 or any Purchaser, and their respective heirs, executors,
administrators, successors and assigns, 

                                      -22-
<PAGE>
 
and no other person shall acquire or have any right under or by virtue of this
Agreement. No purchaser of any of the Securities from any Purchaser 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.

     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 respective counterparts shall together constitute one and
the same instrument.

                                      -23-

     If the foregoing is in accordance with your understanding, please sign and
return to us one for the Company and each of the Purchasers plus one for each
counsel counterparts hereof, and upon the acceptance hereof by you, on behalf of
each of the Purchasers, this letter and such acceptance hereof shall constitute
a binding agreement between each of the Purchasers and the Company.  It is
understood that your acceptance of this letter on behalf of each of the
Purchasers is pursuant to the authority set forth in a form of Agreement among
Purchasers, the form of which shall be submitted to the Company for examination

                                                                         ANNEX I

     (1) The Securities have not been and will not be registered under the
Securities Act and may not be offered or sold within the United States or to, or
for the account or benefit of, U.S. persons except in accordance with Regulation
S under the Securities Act or pursuant to an exemption from the registration
requirements of the Securities Act.  Each Purchaser represents that it has
offered and sold the Securities, and will offer and sell the Securities (i) as
part of their distribution at any time and (ii) otherwise until 40 days after
the later of the commencement of the offering and the Time of Delivery, only in
accordance with Rule 903 of Regulation S or Rule 144A under the Securities Act.
Accordingly, each Purchaser agrees that neither it, its affiliates nor any
persons acting on its or their behalf has engaged or will engage in any directed
selling efforts with respect to the Securities, and it and they have complied
and will comply with the offering restrictions requirement of Regulation S.
Each Purchaser agrees that, at or prior to confirmation of sale of Securities
(other than a sale pursuant to Rule 144A), it will have sent to each
distributor, dealer or person receiving a selling concession, fee or other
remuneration that purchases Securities from it during the distribution
compliance period a confirmation or notice to substantially the following
effect:

          "The Securities covered hereby have not been registered under the U.S.
     Securities Act of 1933 (the "Securities Act") and may not be offered and
     sold within the United States or to, or for the account or benefit of, U.S.
     persons (i) as part of their distribution at any time or (ii) otherwise
     until 40 days after the later of the commencement of the offering and the
     closing date, except in either case in accordance with Regulation S (or
     Rule 144A if available) under the Securities Act.  Terms used above have
     the meaning given to them by Regulation S."

Terms used in this paragraph have the meanings given to them by Regulation S.

     Each Purchaser further agrees that it has not entered and will not enter
into any contractual arrangement with respect to the distribution or delivery of
the Securities, except with its affiliates or with the prior written consent of
the Company.

     (2) Notwithstanding the foregoing, Securities may be offered, sold and
delivered by the Purchasers in the United States and to U.S. persons pursuant to
Section 3(a)(i) of this Agreement without delivery of the written statement
required by paragraph (1) above.

     (3) Each Purchaser further represents and agrees that (i) it has not
offered or sold and prior to the date six months after the date of issue of the
Securities will not offer or sell any Securities to persons in the United
Kingdom except to persons whose ordinary activities involve them in acquiring,
holding, managing or disposing of investments (as principal or agent) for the
purposes of their businesses or otherwise in circumstances which have not
resulted and will not result in an offer to the public in the United Kingdom
within the meaning of the Public Offers of Securities Regulations 1995, (b) it
has complied, and will comply, with all applicable provisions of the Financial
Services Act of 1986 of Great Britain with respect to 

                                      -26-
<PAGE>
 
anything done by it in relation to the Securities in, from or otherwise
involving the United Kingdom, and (c) it has only issued or passed on and will
only issue or pass on in the United Kingdom any document received by it in
connection with the issuance of the Securities to a person who is of a kind
described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 of Great Britain or is a person to whom
the document may otherwise lawfully be issued or passed on.

     (4) Each Purchaser agrees that it will not offer, sell or deliver any of
the Securities  in any jurisdiction outside the United States except under
circumstances that will result in compliance with the applicable laws thereof,
and that it will take at its own expense whatever action is required to permit
its purchase and resale of the Securities in such jurisdictions.  Each Purchaser
understands that no action has been taken to permit a public offering in any
jurisdiction outside the United States where action would be required for such
purpose.  Each Purchaser agrees not to cause any advertisement of the Securities
to be published in any newspaper or periodical or posted in any public place and
not to issue any circular relating to the Securities, except in any such case
with Goldman, Sachs & Co.'s express written consent and then only at its own
risk and expense.

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

         (i) They are independent certified public accountants with respect to
     the Company and its subsidiaries within the meaning of the Securities
     Exchange Act of 1934 (the "Exchange Act") and the applicable published
     rules and regulations thereunder;

         (ii) In our opinion, the consolidated financial statements and
     financial statement schedules audited by us and included in the Offering
     Circular comply as to form in all material respects with the applicable
     requirements of the Exchange Act and the related published rules and
     regulations;

         (iii)  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 Offering Circular
     agrees with the corresponding amounts (after restatements where applicable)
     in the audited consolidated financial statements for such five fiscal
     years;

         (iv) On the basis of limited procedures not constituting an audit 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 in the Offering Circular, 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) the unaudited consolidated statements of income, consolidated
          balance sheets and consolidated statements of cash flows included in
          the Offering Circular are not in conformity with generally accepted
          accounting principles applied on the basis substantially consistent
          with the basis for the unaudited condensed consolidated statements of

Dear KPMG Peat Marwick LLP:

     Goldman, Sachs & Co., as representatives of the Purchasers of 11 1/4%
Senior Notes due 2008 to be issued by Exodus Communications, Inc. (the
"Company"), will be reviewing certain information relating to the Company that
will be included (incorporated by reference) in the Offering Circular.  This
review process, applied to the information relation to the issue, is (will be)
substantially consistent with the due diligence review process that we would
perform if this placement of securities were being registered pursuant to the
Securities Act of 1933 (the Act).  It is recognized however that what is
"substantially consistent" may vary from situation to situation and may not be
the same as that done in a registered offering of the same securities for the
same issuer and whether the procedures being, or to be, followed will be
"substantially consistent" will be determined by us on a case-by-case basis.  We
are knowledgeable with respect to the due diligence review process that would be
performed if this placement of securities were being registered pursuant to the
Act.  We hereby request that you deliver to us a "comfort" letter concerning the
financial statements of the issuer and certain statistical and other data
included in the offering document.  We will contact you to identify the
procedures we wish you to follow and the form we wish the comfort letter to
take.

                                    Very truly yours,

 

                                              (Goldman, Sachs & Co.)
