                          OFFER TO PURCHASE FOR CASH BY

                               GLOBIX CORPORATION

                         ANY AND ALL OF ITS OUTSTANDING

                            13% SENIOR NOTES DUE 2005

                                                                February 8, 2000

Dear Holder,

         We understand that you may beneficially own certain of the 13% Senior
Notes due 2005 (the "Notes") of Globix Corporation, a Delaware corporation (the
"Company"). As more fully described below, the Company is offering to purchase,
for cash (the "Offer"), any and all of these outstanding Notes through a tender
offer that commences at 9:00 a.m., New York City time, on Tuesday, February 8,
2000 and expires at 5:00 p.m., New York City time, on Tuesday, March 7, 2000,
unless otherwise extended by the Company (the "Tender Period"). Lehman Brothers
Inc. ("Lehman Brothers") is the exclusive dealer-manager in connection with the
Offer.

         1. THE OFFER TO PURCHASE. The Company hereby offers to purchase,
commencing at 9:00 a.m., New York City time, on Tuesday, February 8, 2000, any
and all of the Notes at a purchase price of 106.5% of the aggregate principal
amount, plus accrued and unpaid interest on the principal amount up to, but not
including, the Settlement Date (the "Purchase Price"). The "Settlement Date" in
respect of any tendered Notes will be the third New York City business day
following the date on which the registered holder of the Notes (a "Holder")
tenders such Notes and the same are accepted for purchase in accordance with the
Offer (the "Tender Date"). Tenders will be accepted after 9:00 a.m. and before
5:00 p.m., New York City time, on any New York City business day during the
Tender Period, and at such other times during the Tender Period as determined by
Lehman Brothers.

         2. EXPIRATION OF OFFER; PAYMENT FOR NOTES. The Offer will expire at
5:00 p.m., New York City time, on Tuesday, March 7, 2000, unless extended as
provided herein by the Company (such date or the latest date to which the Offer
is extended being the "Expiration Date"). The Company expressly reserves the
right to extend the Offer on a daily basis or from time to time for such period
or periods as the Company may determine in its sole discretion from time to time
by making a public announcement by press release to the Dow Jones News
Service prior to 9:00 a.m., New York City time, on any date not later than the
next business day following the previously scheduled Expiration Date.
<PAGE>   2
         Payment for any Notes purchased pursuant to the Offer will be made on
the applicable Settlement Date, which will be the third New York City business
day following the Tender Date in accordance with the procedures set forth below.
Payment for Notes purchased pursuant to the Offer will be made in immediately
available funds.

         3. NO RECOMMENDATION. NEITHER THE COMPANY NOR LEHMAN BROTHERS MAKES ANY
RECOMMENDATION AS TO WHETHER ANY HOLDER SHOULD TENDER OR REFRAIN FROM TENDERING
ALL OR ANY PORTION OF SUCH HOLDER'S NOTES, AND NO ONE HAS BEEN AUTHORIZED BY
EITHER OF THEM TO MAKE ANY SUCH RECOMMENDATION. HOLDER'S MUST MAKE THEIR OWN
DECISION AS TO WHETHER TO TENDER NOTES, AND IF SO, THE PRINCIPAL AMOUNT OF NOTES
TO TENDER.

         4. THE NOTES. As of the date of this Offer to Purchase, $160 million in
principal amount of Notes were outstanding. The Notes were issued pursuant to
the Original Indenture (as defined below), to which reference is made for a
complete description of the terms of the Notes. The Notes are issued in global
form, and are registered in the name of Cede & Co., the nominee of The
Depository Trust Company.

         5. AMENDMENTS TO THE TERMS OF THE NOTES. In connection with this Offer,
and pursuant to Section 902 of the indenture, dated April 30, 1998, that governs
the Notes (the "Original Indenture"), the Company solicited and received the
consents of the beneficial and record owners of a majority in aggregate
principal amount of the outstanding Notes to amend the Original Indenture and
remove certain restrictive covenants (the "Amendments"). The Company and HSBC
Bank USA, as the trustee, have executed a supplemental indenture, dated February
4, 2000 (the "Supplemental Indenture" and together with the Original Indenture,
the "Indenture"), that incorporates these Amendments. However, the Supplemental
Indenture, by its terms, shall be deemed null and void, and the provisions of
the Original Indenture modified or eliminated by the Supplemental Indenture
shall be immediately reinstated, if the Company fails to purchase, by accepting
for payment, any and all of the Notes that are validly tendered pursuant to the
Offer.

         THE SUPPLEMENTAL INDENTURE IS BINDING ON ALL NON-TENDERING HOLDERS. See
Sections 8, 9 and 10 for discussions of certain factors that you should consider
in evaluating the Offer.

         The summary of the Amendments to the Original Indenture set forth below
is qualified in its entirety by reference to the full and complete terms
contained in the Supplemental Indenture. Holders may obtain copies of the
Supplemental Indenture without charge from the Company. Capitalized terms used
in this section, but not defined herein, shall have the meanings given thereto
in the Indenture.

         The Amendments to the Original Indenture are as follows:

        Restrictive Covenants. The Amendments deleted in their entireties the
following restrictive covenants and any references thereto from the Indenture.

                                       2

                        in respect of stock or (ii) retirement or other payments
                        of obligations subordinated to the Notes prior to the
                        scheduled maturity or scheduled repayment of principal.

         Section 1010 - Limitation on Transactions with Affiliates. Restricted

                        engage in transactions with Affiliates.

         Section 1011 - Limitation on Liens. Restricted the Company and its
                        Subsidiaries from incurring any liens on their property
                        and assets.

         Section 1013 - Limitations on Issuances of Guarantees of Indebtedness.
                        Restricted the ability of Subsidiaries to Guarantee
                        Indebtedness.

         Section 1015 - Limitation on Sale and Leaseback Transactions.

         Section 1017 - Limitation on Dividend and Other Payment Restrictions
                        Affecting Subsidiaries. Restricted the Company and its
                        Subsidiaries from creating or permitting any
                        restrictions which would prevent such Subsidiaries,
                        among other things, from paying dividends, making loans
                        or advances or transferring property or assets to the

                        investments in, or creating, Unrestricted Subsidiaries.

         Section 1019 - Provision of Financial Statements. Required the Company
                        to adhere to certain reporting requirements whether or

                        Exchange Act.

                                       3
<PAGE>   4
         Section 1022 - Limitation on Business. Restricted the Company from
                        engaging in any business which is not substantially an
                        Internet Service Business.

         Article 8. The Amendments also modified Article 8 of the Indenture,
which relates to any sale, assignment, conveyance, transfer or disposition of
all or substantially all of the properties and assets of the Company. In
particular, the Amendments deleted the requirements in Section 801(a) that, as a
condition to any such transaction, the Company:

                      - must be able to incur certain additional indebtedness;

                      - must be able to satisfy certain limitations on liens;
                        and

                      - must not impair any authorization or consent that
                        would have a material adverse affect on the Company's
                        business, financial condition or results of operations.

         Definitions. The Amendments also deleted all definitions from the
Original Indenture that relate solely to the above-mentioned sections of the
Original Indenture because any references to such defined terms would be
eliminated by the Amendments or because they otherwise would not be used.

         6. PURPOSE OF THE OFFER. The purpose of the Offer is to acquire all
outstanding Notes in accordance with the arrangement reached between the Company
and the beneficial owners of a majority of the outstanding principal amount of
the Notes as consideration for the consents to amend the Original Indenture in
accordance with the Supplemental Indenture. There was no additional
consideration for the consents provided in connection with the execution of the
Supplemental Indenture.

         From time to time in the future, the Company or its affiliates may
acquire Notes, if any, which remain outstanding following consummation of the
Offer through open market purchases, privately negotiated transactions, tender
offers, exchange offers or otherwise, upon such terms and at such prices as it
may determine, which may be more or less than the price to be paid pursuant to
the Offer and could be for cash or other consideration. Alternatively, pursuant
to the provisions of the Notes and the Indenture, the Company may choose to
redeem or contractually defease the Notes. There can be no assurance as to
which, if any, of these alternatives (or combinations thereof) the Company will
pursue.

         7. SOURCE AND AMOUNT OF FUNDS. The Company will finance the aggregate
Purchase Price of all Notes validly tendered in the Offer through the receipt of
funds from its $600 million offering of 12.5% Senior Notes due 2010, which
closed on February 8, 2000.

         8. CERTAIN MATTERS RELATED TO THE OFFER. Notes purchased pursuant to
the Offer will be delivered to the Trustee for cancellation. The purchase of
Notes pursuant to the Offer will reduce the aggregate principal amount of Notes
that otherwise might trade publicly, which would adversely affect the liquidity,
market value and price volatility of the remaining Notes held by the public. To
the extent a market continues to exist for any remaining Notes after the

                                       4
<PAGE>   5
consummation of the Offer, the Notes may trade at a discount compared to present
trading prices depending on prevailing interest rates, the market for securities
with similar credit features, the performance of the Company and other factors,
including the elimination of the restrictive covenants in the Original
Indenture. There is no assurance that an active market in the Notes will exist
and no assurance as to the price at which the Notes may trade following the
Offer. To the Company's knowledge, the Notes are traded infrequently in
transactions arranged through brokers and no reliable pricing information for
the Notes is available. Holders of Notes are urged to contact their brokers to
obtain the best available information as to the current market prices.

         Notes not purchased pursuant to the Offer will remain outstanding. The
Amendments eliminate (or, in certain cases, amend) a substantial number of the
restrictive covenants contained in the Indenture with respect to any Notes that
remain outstanding after the Expiration Date and non-tendering Holders thereof
will no longer be entitled to the benefit of (or, in the case of amendments, the
same benefit under) such provisions. The elimination (or, in certain cases,
amendment) of these restrictive covenants may permit the Company to take actions
that could increase the credit risks with respect to the Company faced by
Holders, adversely affect the market price of the remaining Notes or otherwise
be adverse to the interest of Holders.

         9. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The following is a general
summary of certain federal income tax consequences of the adoption of the
Amendments and the sale of Notes to the Company pursuant to the Offer. The
summary does not address the federal income tax consequences to all categories
of Holders, and certain Holders (including insurance companies, partnerships,
tax-exempt organizations, financial institutions, brokers, dealers, nonresident
aliens, foreign corporations, and foreign estates and trusts) might be subject
to special rules not discussed below. This discussion is directed to Holders
which are United States persons and hold the Notes as capital assets. The
summary does not discuss federal tax consequences other than income tax
consequences, and does not discuss foreign, state or local income or other tax
laws. This summary is based upon current provisions of the Internal Revenue Code
of 1986, as amended (the "Code"), applicable Treasury Regulations promulgated
thereunder, judicial authority and current Internal Revenue Service ("IRS")
rulings and practice, all of which are subject to change, possibly on a
retroactive basis.

         EACH HOLDER IS URGED TO CONSULT ITS ADVISOR REGARDING THE FEDERAL,
STATE, LOCAL, FOREIGN AND OTHER TAX CONSEQUENCES OF TENDERING THE NOTES PURSUANT
TO THE OFFER, OR RETAINING THE NOTES, IN LIGHT OF SUCH HOLDER'S PARTICULAR
CIRCUMSTANCES.

         Adoption of the Amendments. Although there is no authority directly on
point, Holders should not recognize any income, gain or loss for federal income
tax purposes as a result of the adoption of the Amendments. The IRS could
assert, however, that as a result of the adoption of the Amendments, Holders
exchanged, within the meaning of Section 1001 of the Code, their Notes for "new"
Notes (the "New Notes"). If the IRS successfully asserts that Holders exchanged
their Notes for New Notes, the deemed exchange should qualify as a
recapitalization for federal income tax purposes, and, as a result, Holders
would generally not recognize gain

                                       5
<PAGE>   6
or loss as a result of the deemed exchange. If a deemed exchange of the Notes
for New Notes were not treated as a recapitalization, subject to the market
discount rules discussed below, Holders would recognize gain or loss on such
deemed exchange equal to the difference between the fair market value of the New
Notes on the date of the deemed exchange and such Holder's adjusted tax basis in
the Notes, and Holders would have a new holding period for the Notes.

         Sale of Notes Pursuant to the Offer. In general, a Holder who receives
cash in exchange for Notes pursuant to the Offer will recognize gain or loss
equal to the difference between the amount of cash received (other than cash
attributable to accrued interest not previously taxed to the Holder, which will
be taxable as ordinary income) and such Holder's adjusted tax basis in such
Notes. Subject to the discussion in "Adoption of the Amendments" above, a
Holder's adjusted tax basis for a Note generally will equal the price such
Holder paid for the Note, increased by any market discount previously included
in income by such Holder pursuant to an election to include market discount in
gross income currently as it accrues and reduced by a portion of amortizable
bond premium which the Holder has previously elected to deduct from gross income
on an annual basis.

         Such gain or loss will be capital gain or loss and will be long term
capital gain or loss if the Holder has held the Note for more than one year at
the time of sale. An exception to the capital gain treatment described above may
apply to a Holder who purchased a Note at a market discount. Subject to a
statutory de minimis exception, market discount is the excess of the principal
amount of such Note over the Holder's tax basis in such Note immediately after
its acquisition by such Holder. In general, unless the Holder has elected to
include market discount in income currently as it accrues (on a straight line
basis or, at the election of the Holder, on a constant interest basis), any gain
recognized by a Holder on the sale of a Note having market discount generally
will be treated as ordinary income to the extent of the market discount that has
accrued while such Note was held by the Holder.

         10. PROCEDURES FOR TENDERING NOTES AND ACCEPTING THIS OFFER. Subject to
the terms of the Offer, tenders will be accepted after 9:00 a.m. and before 5:00
p.m., New York City time, on any New York City business day during the Tender
Period. All tenders will be executed in the customary manner of a corporate bond
trade through Lehman Brothers. Please do not send your Notes to the Company or
Lehman Brothers; rather, follow the tendering procedure described herein.

         If you have an account with Lehman Brothers and desire to tender all or
any portion of the principal amount of your Notes, please contact your
representative at Lehman Brothers. If you do not currently have an account with
Lehman Brothers and desire to tender all or any portion of the principal amount
of your Notes, you must handle this matter through a broker, dealer, commercial
bank, trust company or other financial institution (collectively, a "broker").
Holders will not be required to pay any fee or commission to Lehman Brothers if
such Holders have an account with Lehman Brothers. Holders may, however, be
required to pay fees or commissions if Holders use a broker other than Lehman
Brothers.

                                       6
<PAGE>   7
         If any Holder has any questions regarding how to tender Notes, please
contact Ray Kahn of Lehman Brothers toll-free at (800) 438-3242 or collect at
(212) 528-7581.

         All questions as to the validity, form, eligibility (including time of
receipt), agreement to tender and acceptance of any tender of the Notes shall be
determined by the Company, in its sole discretion, which determination shall be
conclusive and binding. The Company reserves the absolute right to reject, at
any time prior to payment of the Purchase Price for any Notes, any and all
tenders not in proper form or for which acceptance for payment or payment would,
in the opinion of the Company's counsel, be unlawful. The Company also reserves
the absolute right to waive any defects in tender with regard to any particular
Note. Neither the Company nor Lehman Brothers shall be under any duty to give
notification to tendering Holders of any defects or irregularities in tenders,
and neither of them shall incur any liability for failure to give any such
notification. Subject to the foregoing, Notes will be irrevocably accepted when
validly tendered.

         The acceptance of the Offer by a Holder as set forth above will
constitute an agreement between the tendering Holder and the Company in
accordance with the terms and subject to the conditions of the Offer. The
acceptance of the Offer by a tendering Holder will constitute an agreement by
such Holder to deliver good and marketable title to all Notes tendered by such
Holder on the appropriate Settlement Date free and clear of all liens, charges,
claims, encumbrances, interests or restrictions of any kind. A tender of Notes
pursuant to this Offer becomes irrevocable by the relevant Holder at the time of
the tender. The Holder will not have any rights to withdraw Notes once they have
been tendered.

         11. WITHDRAWAL AND AMENDMENT. To the extent legally permitted, the
Company expressly reserves the absolute right, in its sole discretion, to waive
any provision of the Offer or amend any of the terms of the Offer, other than
the Purchase Price or the requirement that Purchase Price be paid in cash. Any
waiver, amendment, or modification to the Offer will apply only to those Notes
which have not been accepted for purchase following their tender to the Company.

         If the Company materially changes the terms of the Offer, the Company
will notify Holders, disseminate additional tender offer materials and extend
the Offer to the extent required by law. Following completion of the Offer, the
Company may purchase additional Notes in the open market, in privately
negotiated transactions, through subsequent tender offers or otherwise. Any
future purchases may be on the same terms or on terms which are more or less
favorable to Holders than the terms of the Offer. Any future purchases by the
Company will depend on various factors existing at that time.

         Any extension or amendment will be followed as promptly as practicable
by public announcement thereof, the announcement in the case of an extension to
be issued no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled applicable Expiration Date. Without limiting the
manner in which the Company may choose to make any public announcement, the
Company shall have no obligation to publish, advertise

                                       7
<PAGE>   8

or otherwise communicate any such public announcement other than by issuing a
release to the Dow Jones News Service.

         12. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE. The Company
currently complies with the informational requirements of Section 13 and 15 of
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and in
accordance therewith files reports and other information with the SEC. Such

retained to act on behalf of the Company as dealer manager in connection with
the Offer and the Company has agreed to pay Lehman a fee upon the acceptance of
the Notes purchased pursuant to the Offer. Lehman Brothers will also be
reimbursed by the Company for Lehman Brothers' reasonable out-of-pocket expenses
incurred in connection with the solicitation and the Offer. The Company has
agreed to indemnify Lehman Brothers against certain liabilities and expenses in
connection with the solicitation and the Offer.

         Lehman Brothers provides other investment banking and financial
advisory services to the Company. At any given time, Lehman Brothers may trade
the Notes for its own account or for the accounts of customers and, accordingly,
may hold a long or short position in the Notes.

pursuant thereto in such state, the Company will make a good faith effort to
comply with any such state statute or seek to have such state statute declared

comply with any such state statute, the Offer will not be made to (nor will
tenders be accepted from or on behalf of) holders of Notes in such state. In any
jurisdiction in which the Offer is required to be made by a licensed broker or
dealer, the Offer is deemed to be made by the dealer manager on behalf of the
Company.

         No person has been authorized to give any information or to make any
representations other than those contained herein and, if given or made, such
information or representations must not be relied upon as having been
authorized. Neither the delivery of this Offer to Purchase and related documents

any implication that the information contained herein or therein is current as
of any time subsequent to the date of such information.

                  FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY
                  BELIEVES IS A "QUALIFIED INSTITUTIONAL BUYER" AS DEFINED IN
                  RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN
                  ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER

                  SECURITY IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE
                  TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE
                  HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. AS USED
                  HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED STATES" AND
                  "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S
                  UNDER THE SECURITIES ACT.

                  You have represented and warranted to the Issuer that you will
make offers (the "Exempt Resales") of the Initial Notes purchased by you
hereunder on the terms set forth in the Offering Memorandum, as amended or
supplemented, solely to (i) persons whom you reasonably believe to be "qualified
institutional buyers," as defined in Rule 144A under the Securities Act
("QIBs"), and (ii) to persons other than U.S. Persons in offshore transactions
meeting the requirements of Rule 903 and 904 of Regulation S under the
Securities Act (such persons specified in clauses (i) and (ii) being referred to
herein as the "Eligible Purchasers"). As used herein, the terms "offshore
transaction" and "U.S. person" have the respective meanings given to them in
Regulation S. You will offer the Initial Notes to Eligible Purchasers initially
at a price equal to 100% of the principal amount thereof. Such price may be
changed at any time without notice.

                  Holders of the Initial Notes (including the Initial Purchasers
and their direct and indirect transferees) will be entitled to the benefits of a
Registration Rights Agreement, dated the Closing Date (as defined in Section 3
below), among the Issuer and the Initial Purchasers, substantially in the form
attached hereto as Annex A (the "Registration Rights Agreement"). Pursuant to
the Registration Rights Agreement, the Issuer will agree to file with the
Securities and Exchange Commission (the "Commission") under the circumstances
set forth therein, (i) a registration statement under the Securities Act (the
"Exchange Offer Registration Statement") relating to the Company's 12.50% Series
B Notes due 2010 (the "New Notes" and, together with the Initial Notes, the
"Notes") to be offered in exchange for the Initial Notes (such offer to exchange
being referred to collectively as the "Exchange Offer") and (ii) a shelf
registration statement pursuant to Rule 415 under the Securities Act (the "Shelf
Registration Statement," and together with the Exchange Offer Registration
Statement, the "Registration Statements") relating to the resale of the Initial
Notes by certain holders of such notes, and to use its best efforts to cause
such Registration Statements to be declared effective. This Agreement, the
Indenture, the Initial Notes, the New Notes and the Registration Rights
Agreement are referred to herein collectively as the "Operative Documents."

                  1. Representations, Warranties and Agreements of the Issuer.
The Issuer represents, warrants to and agrees with, the Initial Purchasers that:

<PAGE>   4
                                                                               4

                  (a) The Preliminary Offering Memorandum did not as of its date
and the Offering Memorandum, did not as of its date and will not as of the
Closing Date, contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; provided that the Issuer does not make any representation
or warranty as to information contained in or omitted from the Preliminary
Offering Memorandum or the Offering Memorandum in reliance upon and in
conformity with written information furnished to the Issuer by or on the behalf
of any Initial Purchaser through Lehman Brothers Inc. specifically for inclusion
therein.

                  (b) The Preliminary Offering Memorandum and the Offering
Memorandum have been prepared by the Issuer for use by the Initial Purchasers in
connection with the Exempt Resales. No order or decree preventing the use of the
Preliminary Offering Memorandum or the Offering Memorandum, or any order
asserting that the transactions contemplated by this Agreement are subject to
the registration requirements of the Securities Act, has been issued and no
proceeding for that purpose has commenced or is pending or, to the knowledge of
the Issuer, is contemplated.

                  (c) Assuming the accuracy of the representations and
warranties of the Initial Purchasers contained in Section 3 and their compliance
with the agreements set forth herein, it is not necessary, in connection with
the issuance and sale of the Initial Notes to the Initial Purchasers and the
offer, resale and delivery of the Initial Notes by the Initial Purchasers in the
manner contemplated by this Agreement and the Offering Memorandum, to register
the Initial Notes under the Securities Act or to qualify the Indenture under the
United States Trust Indenture Act of 1939, as amended (the "Trust Indenture
Act").

                  (d) Each of the Issuer and its material subsidiaries has been
duly incorporated, is validly existing as a corporation in good standing under
the laws of its jurisdiction of incorporation and has the corporate power and
authority to carry on its business as described in the Offering Memorandum and
to own, lease and operate its properties, and each is duly qualified and is in
good standing as a foreign corporation authorized to do business in each
jurisdiction in which the nature of its business or its ownership or leasing of
property requires such qualification, except where the failure to be so
qualified would not have a material adverse effect on the business, earnings,
prospects, financial condition or results of operations of the Issuer and its
subsidiaries, taken as a whole ("Material Adverse Effect"). The following list
constitutes the Issuer's only material subsidiaries: NAFT International Ltd.,
NAFT Computer Service Corp., ATC Merger Corp., PFM Communications, Inc., Globix
Limited, GLX Leasing Limited and Globix Holding U.K. Ltd.

                  (e) The Issuer has an authorized capitalization as set forth
in the Offering Memorandum, and all of the issued and outstanding shares of
capital stock of the Issuer have been duly and validly authorized and issued,
are fully paid and nonassessable and conform to the description thereof
contained in the Offering Memorandum. Except as otherwise disclosed in the
Offering Memorandum, all of the issued and outstanding shares of capital stock
owned directly or indirectly by the Issuer of each subsidiary of the Issuer have
been duly and validly authorized
<PAGE>   5
                                                                               5

indirectly by the Issuer, free and clear of all liens, encumbrances, equities or
claims (each, a "Lien"). Except as set forth in the Offering Memorandum, the
Issuer does not own, directly or indirectly, any shares of stock or any other
equity or long-term debt securities of any corporation or have any equity
interest in any firm, partnership, joint venture, association or other entity,
other than its subsidiaries and interests with a book value of less than $20.0
million and which do not require (by contract, law or otherwise) any additional
investments to be made. Complete and correct copies of the certificates of
incorporation and of the by-laws (or other organizational or constitutive
documents) of the Issuer and each of the material subsidiaries, and all
amendments thereto, have been delivered to the Initial Purchasers, and no
changes will be made between to the date hereof and the Closing Date.

                  (f) The execution, delivery and performance of the Operative
Documents by the Issuer and the consummation of the transactions contemplated
hereby and thereby, including the issuance of the Initial Notes and the New
Notes, will not (w) conflict with or result in a breach or violation of any of
the terms or provisions of, or constitute a default under (or with the giving of
notice or the passage of time or both would constitute a default under), any
indenture, mortgage, deed of trust, loan agreement or other agreement or
instrument to which the Issuer or any of its subsidiaries is a party or by which
the Issuer or any of its subsidiaries is bound or to which any of the properties
or assets of the Issuer or any of its subsidiaries is subject, (x) result in any
violation of the provisions of the certificate of incorporation, by-laws or
other constitutive document of the Issuer or any of its subsidiaries, (y) result
in the suspension, termination or revocation of any Authorization (as defined
below) of the Issuer or any of its subsidiaries or any other impairment of the
rights of the holder of any such authorization or (z) result in any violation of
any statute or any order, rule or regulation of any court or governmental agency
or body having jurisdiction over the Issuer or any of its subsidiaries or any of
their properties or assets, except, with respect to clauses (w) and (z), to the
extent that any conflict, breach or violation thereof would not result in a
Material Adverse Effect; and no consent, approval, authorization or order of, or
filing or registration with, any such court or governmental agency or body is
required for the execution, delivery and performance of the Operative Documents
by the Issuer, and the consummation of the transactions contemplated hereby and
thereby except (i) with respect to the transactions contemplated by the
Registration Rights Agreement, as may be required under the Securities Act, the
Trust Indenture Act and the rules and regulations of the Commission thereunder
and (ii) as required by state securities laws.

                  (g) There are no legal or governmental actions, suits, claims,
arbitrations or proceedings pending or, to the best of Issuer's knowledge,
threatened to which the Issuer or any of its subsidiaries is or could reasonably
be expected to be a party or to which any of their respective property is or
could reasonably be expected to be subject that are required to be described in
the Offering Memorandum and are not so described; nor are there any statutes,
regulations, contracts or other documents that are required to be described in
the Offering Memorandum that are not so described as required.

                  (h) Neither the Issuer nor any of its subsidiaries has
violated any foreign, federal, state or local law or regulation relating to the
protection of human health and safety, the environment or hazardous or toxic
substances or wastes, pollutants or contaminants (collectively,
<PAGE>   6
                                                                               6

"Environmental Laws"), any provisions of the Employee Retirement Income Security
Act of 1974, as amended, or any provisions of the Foreign Corrupt Practices Act
or the rules and regulations promulgated thereunder, except for such violations
which, singly or in the aggregate, would not have a Material Adverse Effect.

                  (i) Each of the Issuer and its subsidiaries has such permits,
licenses, consents, exemptions, franchises, authorizations and other approvals
(each, an "Authorization") of, and has made all filings with and notices to, all
governmental or regulatory authorities and self-regulatory organizations and all
courts and other tribunals, including, without limitation, under any applicable
Environmental Laws, as are necessary to own, lease, license and operate its
respective properties and to conduct its business, except where the failure to
have any such Authorization or to make any such filing or notice would not,
singly or in the aggregate, have a Material Adverse Effect. Each such
Authorization is valid and in full force and effect and each of the Issuer and
its subsidiaries is in compliance with all the terms and conditions thereof and
with the rules and regulations of the authorities and governing bodies having
jurisdiction with respect thereto; and no event has occurred (including, without
limitation, the receipt of any notice from any authority or governing body)
which allows or, after notice or lapse of time or both, would allow, revocation,
suspension or termination of any such Authorization or results or, after notice
or lapse of time or both, would result in any other impairment of the rights of
the holder of any such Authorization; and such Authorizations contain no
restrictions that are burdensome to the Issuer or any of its subsidiaries;
except where such failure to be valid and in full force and effect or to be in
compliance, the occurrence of any such event or the presence of any such
restriction would not, singly or in the aggregate, have a Material Adverse
Effect.

                  (j) After due inquiry, the Issuer reasonably believes that
there are no costs or liabilities associated with Environmental Laws (including,
without limitation, any capital or operating expenditures required for clean-up,
closure of properties or compliance with Environmental Laws or any
Authorization, any related constraints on operating activities and any potential
liabilities to third parties) which would, singly or in the aggregate, have a
Material Adverse Effect.

                  (k) The Issuer has full power and authority to execute,
deliver and perform its obligations under this Agreement; this Agreement and the
transactions contemplated hereby have been duly authorized, executed and
delivered by the Issuer; the Issuer has taken, received or fulfilled all
actions, authorizations and conditions necessary in connection with this
Agreement and the transactions contemplated hereby; and this Agreement
constitutes the legal, valid and binding agreement of the Issuer, enforceable
against the Issuer in accordance with its terms, except as the enforceability
thereof may be limited by (i) applicable bankruptcy, insolvency, reorganization,
moratorium or other laws now or hereafter in effect relating to or affecting
creditors' rights generally and (ii) general principles of equity (regardless of
whether such enforcement is considered in a proceeding in equity or at law) and
except to the extent that rights to indemnification thereunder may be limited by
applicable federal or state securities laws or unenforceable as against public
policy.

Statement, will be qualified under the Trust Indenture Act; on the Closing Date,
the Indenture will have been duly executed and delivered by the Issuer and,
assuming due authorization, execution and delivery of the Indenture by the
Trustee, the Indenture will constitute a valid and legally binding obligation of
the Issuer, enforceable in accordance with its terms, except that the
enforcement thereof may be subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) and an implied covenant of good
faith and fair dealing; and that, to the extent the Indenture is described in
the Offering Memorandum, such description conforms in all material respects with
the terms and conditions of the Indenture.

                  (m) The Issuer has full corporate power and authority to issue
and sell the Initial Notes; the Initial Notes have been duly authorized by the

Agreement on the Closing Date, such Initial Notes will have been duly executed,
authenticated, issued and delivered in accordance with the provisions of the
Indenture and, assuming due authentication of the Initial Notes by the Trustee,
such Initial Notes will constitute valid and legally binding obligations of the
Issuer, entitled to the benefits of the Indenture and enforceable in accordance
with their terms, except that the enforcement thereof may be subject to
bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered in a proceeding in equity or at law)
and an implied covenant of good faith and fair dealing; and the Initial Notes
conform in all material respects to the description thereof contained in the
Offering Memorandum.

                  (n) The Issuer has full corporate power and authority to issue
the New Notes; the New Notes have been duly and validly authorized by the
Company and if and when duly issued and authenticated in accordance with the
terms of the Indenture and, assuming due authentication of the New Notes by the
Trustee, upon delivery in accordance with the Exchange Offer provided for in the
Registration Rights Agreement, will constitute valid and binding obligations of
the Company entitled to the benefits of the Indenture, enforceable against the

                  (o) The Issuer has full corporate power and authority to enter
into the Registration Rights Agreement; the Registration Rights Agreement and
the transactions contemplated thereby have been duly authorized by the Issuer;
when the Registration Rights Agreement is duly executed and delivered by the
Issuer (assuming due authorization, execution and delivery by the Initial
Purchasers), it will be a valid and legally binding obligation of the Issuer,
enforceable against the Issuer in accordance with its terms, except that the
enforcement thereof may be subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and other similar laws relating to or
affecting creditors' rights generally, general equitable principles (whether
considered in a proceeding in equity or at law) and an implied

covenant of good faith and fair dealing, and except with respect to the rights
of indemnification and contribution thereunder, where enforcement thereof may be

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, except for losses and interferences which do not, in the aggregate, have
a Material Adverse Effect; and, since such date, (i) there has not been any
change resulting in, or any development involving a prospective change which is
reasonably likely to result in, a Material Adverse Effect, (ii) there has not
been any material adverse change or any development involving a prospective

related schedules and notes, present fairly the consolidated financial position,
results of operations and changes in financial position of the Issuer and its

                  (t) The Issuer and each of its subsidiaries have good and
marketable title to all real property and good and marketable title to all

property and do not materially interfere with the use made and proposed to be
made of such property by the Issuer and its subsidiaries; and all real property

except as described in the Offering Memorandum.

                  (u) Except as otherwise set forth in the Preliminary Offering

have a Material Adverse Effect.

                  (w) No relationship, direct or indirect, exists between or
among the Issuer or any of its subsidiaries on the one hand, and the directors,

price the Initial Notes in the form of one or more permanent global certificates
(the "Global Notes"), deposited with DTC or its nominee. Beneficial interests in
the Notes will be shown on, and transfers thereof will be effected only through,
records maintained in book-entry form by DTC and its participants.

                  4. Further Agreements of the Issuer. The Issuer agrees:

<PAGE>   15
                                                                              15

                  (a) The Issuer will advise the Initial Purchasers promptly of
any proposal to amend or supplement the Offering Memorandum and will not effect
such amendment or supplementation to which the Initial Purchasers reasonably
object. If, at any time prior to completion of the resale of the Initial Notes
by the Initial Purchasers (such time not to exceed two years from the Closing
Date), any event shall occur or condition exist as a result of which it is
necessary to amend or supplement the Offering Memorandum in order that the
Offering Memorandum will not include an untrue statement of a material fact or
omit to state a material fact necessary in order to make the statements therein,
in the light of the circumstances existing at the time it is delivered to a
purchaser, not misleading, the Issuer shall promptly notify the Initial
Purchasers of such event or occurrence and shall promptly prepare, subject to
the first sentence of this Section 4(a), such amendment or supplement as may be
necessary to correct such untrue statement or omission. Neither the Initial
Purchasers' consent to, nor their delivery to offerees or investors of, any such
amendment or supplement shall constitute a waiver of any of the conditions set
forth in Section 6.

                  (b) The Issuer will furnish to the Initial Purchasers and to
counsel for the Initial Purchasers copies of the Preliminary Offering Memorandum
and the Offering Memorandum (and all amendments and supplements thereto) in each
case as soon as available and in such quantities as the Initial Purchasers
reasonably requests for internal use and for distribution to prospective
purchasers. The Issuer will pay the expenses of printing and distributing to the
Initial Purchasers all such documents.

                  (c) Promptly from time to time the Issuer will use its
reasonable efforts to take such action as the Initial Purchasers may reasonably
request, in cooperation with the Initial Purchasers, to qualify the Initial
Notes for offering and sale under the securities laws of such jurisdictions as
the Initial Purchasers may request and to comply with such laws so as to permit
the continuance of sales and dealings therein in such jurisdictions in the
United States or Canada for as long as may be necessary to complete the resale
of the Initial Notes; provided that in connection therewith the Issuer shall not
be required to qualify as a foreign corporation or otherwise subject itself to
taxation in any jurisdiction in which it is not otherwise so qualified or
subject.

                  (d) The Issuer will apply the proceeds from the sale of the
Initial Notes as set forth under "Use of Proceeds" in the Offering Memorandum.

                  (e) Until the second anniversary of the last Closing Date, the
Issuer will, upon request, furnish to the Initial Purchasers and any holder of
Transfer Restricted Securities (as defined in the Registration Rights
Agreement), a copy of the restrictions on transfer which the Issuer believes are
applicable to the Transfer Restricted Securities; provided, however, that
nothing contained herein shall obligate the Issuer to track or trace particular
Transfer Restricted Securities held by anyone other than the Issuer or any of
its affiliates (as defined in Rule 144 under the Securities Act).

<PAGE>   16
                                                                              16

                  (f) In connection with the offering of the Initial Notes,
until the Initial Purchasers shall have notified the Issuer of the completion of
the resale of the Initial Notes, none of the Issuer, or any of its affiliates
has or will, either alone or with one or more other persons, take any action,
directly or indirectly, which is designed to or which has constituted or which
might reasonably have been expected to cause or result in stabilization or
manipulation of the price of any security of the Issuer in connection with the
offering of the Initial Notes.

                  (g) For a period of 90 days after the date hereof, the Issuer,
its direct or indirect subsidiaries and its affiliates will not offer, sell,
contract to sell, pledge or otherwise dispose of, directly or indirectly, any
debt securities issued or guaranteed by the Issuer or any of its affiliates and
subsidiaries (except the New Notes in connection with the Exchange Offer),
without the prior written consent of Lehman Brothers Inc. Neither the Issuer nor
any of its direct or indirect subsidiaries will at any time offer, sell,
contract to sell, pledge or otherwise dispose of, directly or indirectly, any
securities under circumstances where such offer, sale, pledge, contract or
disposition would cause the exemption afforded by Section 4(2) of the Securities
Act to cease to be applicable to the offer and sale of the Initial Notes.

                  (h) So long as any of the Initial Notes are "restricted
securities" within the meaning of Rule 144 (a) (3) under the Securities Act, the
Issuer will provide to any holder of the Initial Notes or to any prospective
purchaser of the Initial Notes designated by any holder, upon request of such
holder or prospective purchaser, information required to be provided by Rule
144A (d) (4) or Rule 144(c) of the Securities Act if, at the time of such
request, the Issuer is not subject to the reporting requirements under Section
13 or 15 (d) of the Exchange Act.

                  (i) Each of the Initial Notes will bear, to the extent
applicable, the applicable legend contained in "Notice to Investors" in the
Offering Memorandum for the time period and upon the other terms stated therein,
except after the Initial Notes are resold pursuant to a registration statement
effective under the Securities Act.

                  (j) The Issuer will take such steps as shall be necessary to
ensure that it shall not become an "investment company" within the meaning of
such term under the Investment Company Act, and the rules and regulations of the
Commission thereunder.

                  (k) The Issuer will use its best efforts to arrange for the
Notes to be accepted for clearance and settlement through DTC. In addition, the
Issuer will use its best efforts to cause the Initial Notes to be eligible for
inclusion in the Portal Market.

                  (l) The Issuer will cause all Notes to be listed on each
securities exchange or automated quotation system on which similar securities
issued by the Issuer are then listed prior to the effectiveness of the
Registration Statement.

                  5. Expenses. The Issuer agrees to pay (a) the costs incident
to the authorization, issuance, sale and delivery of the Notes, and any taxes
payable in that connection; (b) the costs incident to the preparation, printing
and distribution of the Preliminary Offering Memorandum, the Offering Memorandum
and any amendment or supplement to the Offering Memorandum, all

                                                                              17

as provided in this Agreement; (c) the costs of producing and distributing the
Operative Documents; (d) the fees and expenses of qualifying the Notes under the
securities laws of the several jurisdictions as provided in Section 4(c) and of
preparing, printing and distributing a Blue Sky Memorandum (including reasonable
related fees and expenses of counsel to the Initial Purchasers); (e) all costs
and expenses incident to (i) the preparation of the "road show" presentation
materials and (ii) the road show travelling expenses of the Issuer; (f) the
costs of preparing the Global Notes; (g) all expenses and fees in connection
with the application for inclusion of the Initial Notes in the PORTAL Market,
and the inclusion of the Notes on each securities exchange or automated
quotation system on which similar securities issued by the Issuer are listed;
(h) the fees and expenses (including fees and disbursements of counsel) of the
Trustee; (i) the cost and charges of any transfer agent or registrar; (j) all
stamp or other issuance or transfer taxes or governmental duties, if any,
payable by the Initial Purchasers in connection with the offer and sale of the
Initial Notes to the Initial Purchasers and by the Initial Purchasers to the
initial purchasers thereof; and (k) all other costs and expenses incident to the
performance of the obligations of the Issuer under this Agreement not otherwise
specifically provided for in this Section including, without limitation, the
fees and expenses of Arthur Andersen LLP, the Issuer's independent accountants,
and the fees and expenses of Milberg Weiss Bershad Hynes & Lerach LLP and
Skadden, Arps, Slate, Meagher & Flom LLP, counsels to the Issuer, but not
including the fees of Simpson Thacher and Bartlett, counsel to the Initial
Purchasers.

                  6. Conditions of the Initial Purchasers' Obligations. The
several obligations of the Initial Purchasers hereunder are subject to the
accuracy, when made and on the Closing Date, of the representations and
warranties of the Issuer contained herein, to the performance by the Issuer of
its obligations hereunder, and to each of the following additional terms and
conditions:

                  (a) No Initial Purchaser shall have discovered and disclosed
to the Issuer on or prior to the Closing Date that the Offering Memorandum or
any amendment or supplement thereto contains any untrue statement of a fact
which, in the opinion of counsel to the Initial Purchasers, is material or omits
to state any fact which is material and is required to be stated therein or is
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

                  (b) All corporate proceedings and other legal matters incident
to the authorization, form and validity of the Operative Documents and the
Offering Memorandum or any amendment or supplement thereto, and all other legal
matters relating to the Operative Documents and the transactions contemplated
thereby shall be satisfactory in all material respects to counsel to the Initial
Purchasers, and the Issuer shall have furnished to such counsel all documents
and information that they may reasonably request to enable them to pass upon
such matters.

                  (c) Milberg Weiss Bershad Hynes & Lerach LLP shall have

Thacher & Bartlett, counsel for the Initial Purchasers, such opinion or
opinions, dated as of the Closing Date, with respect to the issuance and sale of
the Initial Notes, the Offering Memorandum and other related matters as the
Initial Purchasers may reasonably require, and the Issuer shall have furnished
to such counsel such documents as they reasonably request for the purpose of
enabling them to pass upon such matters.

                  (h) The Trustee shall have furnished to the Initial Purchasers

satisfactory to the Initial Purchasers, to the effect that (i) the Indenture has
been duly authorized, executed and delivered by the Trustee, (ii) each person

changes or developments since the respective dates as of which specified
financial information is given in the Offering Memorandum, as of a date not more
than three days prior to the date of the bring-down letter), the conclusions and
findings of such firm with respect to the financial information and other
matters covered by the initial letter and (iii) confirming in all material

                                                                              19

                  (j) The Issuer shall have furnished to the Initial Purchasers
a certificate, dated the Closing Date, of its Chief Executive Officer, President
or Vice President and Chief Financial Officer in form and to the effect that:

                  (i) The representations, warranties and agreements of the
         Issuer in Section 1 are true and correct as of the Closing Date; the
         Issuer has complied in all material respects with all its agreements
         contained herein to be performed on or prior to the Closing Date, and
         the conditions set forth in Section 6 have been fulfilled;

                  (ii)(A) Except as disclosed in the Offering Memorandum,
         neither the Issuer nor any of its subsidiaries has sustained, since the
         date of the latest audited financial statements included in the
         Offering Memorandum, any loss or interference with its business from
         fire, explosion, flood or other calamity, whether or not covered by
         insurance, or from any labour dispute or court or governmental action,
         order or decree, except for losses and interferences which do not, in
         the aggregate, have a Material Adverse Effect; and (B) since such date,
         there has not been any change resulting in, or any development
         involving a prospective change which is likely to result in, a Material
         Adverse Effect, other than as set forth or contemplated in the Offering
         Memorandum;

                  (iii) They have carefully examined the Offering Memorandum
         and, in their opinion (A) the Offering Memorandum, as of the Closing
         Date, did not include any untrue statement of a material fact and did
         not omit to state any material fact required to be stated therein or
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, and (B) since
         the date of the Offering Memorandum, no event has occurred which would
         have been required to be set forth in a supplement or amendment to the
         Offering Memorandum had the Offering Memorandum been filed as part of
         the Registration Statement on Form S-1 under the Securities Act.

                  (k) (i) Neither the Issuer nor any of its subsidiaries shall
have sustained since the date of the latest audited financial statements
included in the Offering Memorandum 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 Memorandum
or (ii) since such date there shall not have been 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 Issuer
and its subsidiaries, taken as a whole, otherwise than as set forth or
contemplated in the Offering Memorandum, the effect of which, in any such case
described in clause (i) or (ii), is, in the reasonable judgment of the Initial
Purchasers, so material and adverse as to make it impracticable or inadvisable
to proceed with the sale or the delivery of the Initial Notes being delivered on
the Closing Date on the terms and in the manner contemplated in the Offering
Memorandum.

                                                                              20

                  (l) Subsequent to the execution and delivery of this Agreement
(i) no downgrading shall have occurred in the rating accorded the Issuer'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 Issuer's debt securities.

                  (m) Subsequent to the execution and delivery of this Agreement
there shall not have occurred any of the following: (i) trading in securities
generally on the New York Stock Exchange or the Nasdaq National Market System,
or trading in any securities of the Issuer on any exchange shall have been
suspended or minimum prices shall have been established on any such exchange by
the Commission, by such exchange or by any other regulatory body or governmental
authority having jurisdiction, (ii) a banking moratorium on commercial banking
activities in New York shall have been declared by United States federal or
state authorities, (iii) the United States shall have become engaged in
hostilities, there shall have been an escalation in hostilities involving the
United States, or there shall have been a declaration of a national emergency or
war by the United States, or (iv) there shall have occurred any change in
financial markets or any calamity or crisis that in the sole judgment of the
Initial Purchasers is material and adverse, and in the case of any of the events
specified in clauses (i) through (iv), such event singly or together with any
other such event makes it, in the judgment of the Initial Purchasers,
impracticable to market the Initial Notes on the terms and in the manner
contemplated in the Offering Memorandum.

                  (n) The Indenture shall have been duly executed and delivered
by the Issuer and the Trustee and the Initial Notes shall have been duly
executed and delivered by the Issuer and duly authenticated by the Trustee.

                  (o) The Issuer and the Initial Purchasers shall have executed
and delivered the Registration Rights Agreement (in form and substance
satisfactory to the Initial Purchasers) and the Registration Rights Agreement
shall be in full force and effect.

                  (p) The NASD shall have accepted the Initial Notes for trading
on PORTAL and the Notes shall have been accepted for clearance and settlement
through DTC.

                  (q) There shall not have occurred any invalidation of Rule
144A under the Securities Act by any court or any withdrawal of any rule or
regulation under the Securities Act or the Exchange Act by the Commission or any
amendment thereof by the Commission which in the judgment of the Initial
Purchasers would materially impair the ability of the Initial Purchasers to
purchase, hold or effect resales of the Initial Notes as contemplated hereby.

                  (r) A supplemental indenture to the Indenture dated April 30,
1998, relating to the Issuer's 13% Senior Notes due 2005 shall have been
executed by the Issuer and HSBC Bank USA and delivered to the Initial Purchasers
in form and substance reasonably satisfactory to the Issuer and the Initial
Purchasers.

<PAGE>   21
                                                                              21

                  (s) The Issuer shall have furnished to the Initial Purchasers
and their counsel such further information, certificates and documents as the
Initial Purchasers may reasonably request to evidence compliance with the
conditions set forth in this Section 6.

                  All opinions, letters, evidence and certificates mentioned
above or elsewhere in this Agreement shall be deemed to be in compliance with
the provisions hereof only if they are in form and substance satisfactory to
counsel to the Initial Purchasers.

                  7.  Indemnification and Contribution.

                  (a) The Issuer shall indemnify and hold harmless each Initial
Purchaser, its officers and employees and each person, if any, who controls any
Initial Purchaser within the meaning of the Securities Act, from and against any
loss, claim, damage or liability, joint or several, or any action in respect
thereof (including, but not limited to, any loss, claim, damage, liability or
action relating to purchases and sales of the Notes), to which that Initial
Purchaser, officer, employee or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Offering
Memorandum or the Offering Memorandum, or in any amendment or supplement
thereto, or in any blue sky application or other document prepared or executed
by the Issuer (or based upon any written information furnished by the Issuer)
specifically for the purpose of qualifying any or all of the Notes under the
securities laws of any state or other jurisdiction (such application, document
or information being hereinafter called a "Blue Sky Application") or (ii) the
omission or alleged omission to state in any Preliminary Offering Memorandum or
the Offering Memorandum, or in any amendment or supplement thereto, or in any
Blue Sky Application or in any material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse
each Initial Purchaser and each such officer, employee and controlling person
promptly upon demand for any legal or other expenses reasonably incurred by that
Initial Purchaser, officer, employee or controlling person in connection with
investigating or defending or preparing to defend against any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Issuer shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or action arises out of, or is based upon, any
untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Offering Memorandum or the Offering Memorandum, or in
any such amendment or supplement, or in any Blue Sky Application in reliance
upon and in conformity with the written information furnished to the Issuer by
any Initial Purchaser specifically for inclusion therein and described in
Section 7(e). The foregoing indemnity agreement is in addition to any liability
which the Issuer may otherwise have to any Initial Purchaser or to any officer,
employee or controlling person of that Initial Purchaser.

                  (b) Each Initial Purchaser, severally and not jointly, shall
indemnify and hold harmless the Issuer, each of its respective officers and
directors, and each person, if any, who controls the Issuer within the meaning
of the Securities Act from and against any loss, claim, damage or liability,
joint or several, or any action in respect thereof, to which the Issuer or any
such director, officer or controlling person may become subject, under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon,
<PAGE>   22
                                                                              22

(i) any untrue statement or alleged untrue statement of a material fact
contained (A) in any Preliminary Offering Memorandum or the Offering Memorandum
or in any amendment or supplement thereto, or (B) in any Blue Sky Application or
(ii) the omission or alleged omission to state therein any material fact
required to be stated in any Preliminary Offering Memorandum or the Offering
Memorandum, or in any Blue Sky Application, or necessary to make the statements
therein not misleading, but in each case only to the extent that the untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with the written information furnished to the
Issuer through the Initial Purchasers specifically for inclusion therein and
described in Section 7(e), and shall reimburse the Issuer and any such director,
officer or controlling person for any legal or other expenses reasonably
incurred by the Issuer or any such director, officer or controlling person in
connection with investigating or defending or preparing to defend against any
such loss, claim, damage, liability or action as such expenses are incurred. The
foregoing indemnity agreement is in addition to any liability which any Initial
Purchaser may otherwise have to the Issuer or any such director, officer or
controlling person.

                  (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of any claim or the commencement of any action, the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying party under this Section 7, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 7 except to the extent it has
been materially prejudiced by such failure and, provided, further, that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified party otherwise than under this Section 7.
If any such claim or action shall be brought against an indemnified party, and
it shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel satisfactory to the indemnified party. After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 7 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
any indemnified party shall have the right to employ separate counsel in any
such action and to participate in the defense thereof but the fees and expenses
of such counsel shall be at the expense of such indemnified party unless (i) the
employment thereof has been specifically authorized by the indemnifying party in
writing, (ii) such indemnified party shall have been advised by such counsel
that there may be one or more legal defenses available to it which are different
from or additional to those available to the indemnifying party and in the
reasonable judgment of such counsel it is advisable for such indemnified party
to employ separate counsel or (iii) the indemnifying party has failed to assume
the defense of such action and employ counsel reasonably satisfactory to the
indemnified party, in which case, if such indemnified party notifies the
indemnifying party in writing that it elects to employ separate counsel at the
expense of the indemnifying party, the indemnifying party shall not have the
right to assume the defense of such action on behalf of such indemnified party,
it being understood, however, that the indemnifying party shall not, in
connection with any one such action or separate but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or
<PAGE>   23
                                                                              23

circumstances, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys (in addition to local counsel, if necessary) at any
time for all such indemnified parties, which firm shall be designated in writing
by Lehman Brothers Inc., if the indemnified parties under this Section 7 consist
of any Initial Purchasers or any of their respective officers, employees or
controlling persons, or by the Issuer, if the indemnified parties under this
Section consist of the Issuer or any of its directors, officers, employees or
controlling persons. Each indemnified party, as a condition of the indemnity
agreements contained in Sections 7(a) and 7(b), shall use its best efforts to
cooperate with the indemnifying party in the defense of any such action or
claim. No indemnifying party shall (i) without the prior written consent of the
indemnified parties (which consent shall not be unreasonably withheld) settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent (a) includes an unconditional
release of each indemnified party from all liability arising out of such claim,
action, suit or proceeding and (b) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
indemnified party, or (ii) be liable for any settlement of any such action
effected without its written consent (which consent shall not be unreasonably
withheld), but if settled with its written consent or if there be a final
judgment of the plaintiff in any such action, the indemnifying party agrees to
indemnify and hold harmless any indemnified party from and against any loss of
liability by reason of such settlement or judgment. Notwithstanding the
foregoing, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by this paragraph, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement.

                  (d) If the indemnification provided for in this Section 7
shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party under Section 7(a) or 7(b) in respect of any loss, claim,
damage or liability, or any action in respect thereof, referred to therein, then
each indemnifying party shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such indemnified party as a result
of such loss, claim, damage or liability, or action in respect thereof, (i) in
such proportion as shall be appropriate to reflect the relative benefits
received by the Issuer on the one hand and the Initial Purchasers on the other
from the offering of the Notes or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Issuer on the one hand and the Initial Purchasers
on the other with respect to the statements or omissions which resulted in such
loss, claim, damage or liability, or action in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Issuer on the one hand and the Initial Purchasers on the other with respect to
such offering shall be deemed to be in the same
<PAGE>   24
                                                                              24

proportion as the total net proceeds from the offering of the Notes purchased
under this Agreement (before deducting expenses) received by the Issuer on the
one hand, and the total discounts and commissions received by the Initial
Purchasers with respect to the Notes purchased under this Agreement, on the
other hand, bear to the total gross proceeds from the offering of the Notes
under this Agreement, in each case as set forth in the table on the cover page
of the Offering Memorandum. The relative fault shall be determined by reference
to whether the untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact relates to information supplied by
the Issuer or the Initial Purchasers, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission. The Issuer and the Initial Purchasers agree that it
would not be just and equitable if contributions pursuant to this Section 7(d)
were to be determined by pro rata allocation (even if the Initial Purchasers
were treated as one entity for such purpose) or by any other method of
allocation which does not take into account the equitable considerations
referred to herein. The amount paid or payable by an indemnified party as a
result of the loss, claim, damage or liability, or action in respect thereof,
referred to above in this Section 7(d) shall be deemed to include, for purposes
of this Section 7(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The Initial
Purchasers' obligations to contribute as provided in this Section 7(d) are
several in proportion to their respective purchase obligations and not joint.

                  (e) The Initial Purchasers severally confirm that the
statements with respect to the offering of the Initial Notes set forth in the
fourth, sixth, seventh and eighth paragraphs under the caption "Plan of
Distribution" in the Offering Memorandum are correct and constitute the only
information furnished in writing to the Issuer by or on behalf of the Initial
Purchasers specifically for inclusion in the Offering Memorandum.

                  8.  Defaulting Initial Purchasers.

                  If, on the Closing Date, any Initial Purchaser defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Initial Purchasers shall be obligated to purchase the aggregate
principal amount of Initial Notes which the defaulting Initial Purchaser agreed
but failed to purchase on the Closing Date in the respective proportions which
the total aggregate principal amount of Initial Notes set opposite the name of
each remaining non-defaulting Initial Purchaser in Schedule 1 hereto bears to
the total aggregate principal amount of Notes set opposite the names of all the
remaining non-defaulting Initial Purchasers in Schedule 1 hereto; provided,
however, that the remaining non-defaulting Initial Purchasers shall not be
obligated to purchase any Initial Notes on the Closing Date if the total
aggregate principal amount of Initial Notes which the defaulting Initial
Purchasers agreed but failed to purchase on such date exceeds 9.09% of the total
aggregate principal amount at maturity of Initial Notes to be purchased on the
Closing Date, and any remaining non-defaulting Initial Purchaser shall not be
obligated to purchase more than 110% of the aggregate principal amount at
maturity of Initial Notes which it agreed to purchase on the Closing Date
pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the
remaining non-defaulting Initial Purchasers, or those
<PAGE>   25
                                                                              25

other underwriters satisfactory to the Initial Purchasers who so agree, shall
have the right, but shall not be obligated, to purchase on the Closing Date, in
such proportion as may be agreed upon among them, the total aggregate principal
amount of Initial Notes to be purchased on the Closing Date. If the remaining
Initial Purchasers or other underwriters satisfactory to the Initial Purchasers
do not elect to purchase on the Closing Date the aggregate principal amount of
Initial Notes which the defaulting Initial Purchasers agreed but failed to
purchase, this Agreement shall terminate without liability on the part of any
non-defaulting Initial Purchasers and the Issuer, except that the Issuer will
continue to be liable for the payment of expenses to the extent set forth in
Sections 5 and 10. As used in this Agreement, the term "Initial Purchaser"
includes, for all purposes of this Agreement unless the context requires
otherwise, any party not listed in Schedule 1 hereto who, pursuant to this
Section 8, purchases Initial Notes which a defaulting Initial Purchaser agreed
but failed to purchase.

                  Nothing contained herein shall relieve a defaulting Initial
Purchaser of any liability it may have to the Issuer for damages caused by its
default. If other underwriters are obligated or agree to purchase the Initial
Notes of a defaulting or withdrawing Initial Purchaser, either the remaining
non-defaulting Initial Purchasers or the Issuer may postpone the Closing Date
for up to seven full business days in order to effect any changes that in the
opinion of counsel to the Issuer or counsel to the Initial Purchasers may be
necessary in the Offering Memorandum or in any other document or arrangement.

                  9. Termination. The obligations of the Initial Purchasers
hereunder may be terminated by the Initial Purchasers by notice given to and
received by the Issuer prior to delivery of and payment for the Initial Notes
if, prior to that time, any of the events described in Sections 6(l) and (m)
shall have occurred or if the Initial Purchasers shall decline to purchase the
Initial Notes for any reason permitted under this Agreement.

                  10. Reimbursement of Initial Purchasers' Expenses. If this
Agreement shall be terminated pursuant to Section 9, then the Issuer shall
reimburse the Initial Purchasers for fees and expenses of their counsels and for
such other out-of-pocket expenses as shall have been incurred by them in
connection with this Agreement and the proposed purchase of the Initial Notes,
and upon demand the Issuer shall pay the full amount thereof to the Initial
Purchasers and the Issuer shall have no further liability to the Initial
Purchasers except as provided in Sections 5 and 7.

                  11. Notices, etc. All notices and other communications
provided for or permitted hereunder shall be made in writing by hand delivery,
first-class mail (registered or certified, return receipt requested),

designated by notice to the other parties by like notice.
