Ladies and Gentlemen:

               United Stationers Supply Co., an Illinois corporation (the 
"COMPANY"), a wholly-owned subsidiary of United Stationers Inc., a Delaware 
corporation ("UNITED"), proposes to issue and sell $100,000,000 aggregate 
principal amount of its 8 3/8% Senior Subordinated Notes due 2008 (the 
"NOTES"). The Securities will be issued pursuant to an Indenture to be dated 
as of April 15, 1998 (the "INDENTURE") among the Company, the Guarantors (as 
defined below) and The Bank of New York, as trustee (the "TRUSTEE"). The 
Notes will be unconditionally guaranteed on a senior subordinated basis (the 
"GUARANTEES") initially by each of United, Lagasse Bros., Inc., a Louisiana 
corporation, Azerty Incorporated, a Delaware corporation, Positive ID 
Wholesale Inc., a Delaware corporation and AP Support Services Incorporated, 
a Delaware corporation (collectively, the "GUARANTORS" and, together with the 
Company, the "ISSUERS"), pursuant to the terms of the Indenture. The Notes 
and the Guarantees are sometimes referred to herein together as the 
"SECURITIES." The Issuers hereby confirm their agreement with Chase 
Securities Inc. ("CSI") and Bear, Stearns & Co. Inc. (together with CSI, the 
"INITIAL PURCHASERS") concerning the purchase of the Securities from the 
Company by the several Initial Purchasers.

               The Securities will be offered and sold to the Initial 
Purchasers without being registered under the Securities Act of 1933, as 
amended (the "SECURITIES ACT"), in reliance upon an exemption therefrom. The 
Company has prepared a preliminary offering memorandum dated March 24, 1998 
(the "PRELIMINARY OFFERING MEMORANDUM") and will prepare an offering 
memorandum dated the date hereof (the "OFFERING MEMORANDUM") setting forth 
information concerning the Issuers and the Securities. Copies of the 
Preliminary Offering Memorandum have been, and copies of the Offering 
Memorandum will be, delivered by the Company to the Initial Purchasers 
pursuant to the terms of this Agreement. Any references herein to the 
Preliminary Offering Memorandum and the Offering Memorandum shall be deemed 
to include all amendments and supplements thereto, unless otherwise noted. 
Each of the Issuers hereby confirms that it has authorized the use of the 
Preliminary Offering Memorandum and the 



Offering Memorandum in connection with the offering and resale of the 
Securities by the Initial Purchasers in accordance with Section 2.

               Holders of the Securities (including the Initial Purchasers 
and their direct and indirect transferees) will be entitled to the benefits 
of an Exchange and Registration Rights Agreement, substantially in the form 
attached hereto as Exhibit A (the "REGISTRATION RIGHTS AGREEMENT"), pursuant 
to which the Company will agree to file with the Securities and Exchange 
Commission (the "COMMISSION") (i) a registration statement under the 
Securities Act (the "EXCHANGE OFFER REGISTRATION STATEMENT") registering an 
issue of senior subordinated notes of the Company (the "EXCHANGE NOTES") 
which are identical in all material respects to the Notes and which are 
unconditionally guaranteed by each of the guarantors (such guarantees, 
together with the Exchange Notes, the "EXCHANGE SECURITIES") (except that the 
Exchange Securities will not contain terms with respect to transfer 
restrictions) and (ii) under certain circumstances, a shelf registration 
statement with respect to the resale of the Securities pursuant to Rule 415 
under the Securities Act (the "SHELF REGISTRATION STATEMENT").

               The net proceeds of the offering of the Securities will be 
used by the Company to repay a portion of indebtedness of the Company 
outstanding under a $100.0 million tranche B term loan facility (the "TRANCHE 
B TERM LOAN FACILITY") under the Company's new senior secured credit 
facilities (the "NEW CREDIT FACILITIES"). The Company used the Tranche B Term 
Loan Facility and other drawings under the New Credit Facilities to pay the 
purchase price for the acquisition of the capital stock of Azerty 
Incorporated, Azerty de Mexico, S.A. de C.V., Positive ID Wholesale Inc. and 
AP Support Services Incorporated (the "AZERTY ACQUISITION").

               Capitalized terms used but not defined herein shall have the 
meanings given to such terms in the Offering Memorandum.

         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 Issuers make no representation or
         warranty as to information contained in or omitted from the Preliminary

         Effect; and to the best knowledge of the Company, no such proceedings

         jurisdiction; no action, suit or proceeding is pending against or, to
         the best knowledge of the Company, threatened against or affecting
         United, the Company or any of its subsidiaries before any court or

         foreign, which could reasonably be expected to interfere with or
         adversely affect the issuance of the Securities, the Exchange
         Securities or the Private Exchange Securities or in any manner draw

         material respect, and no event has occurred which, with notice or lapse
         of time or both, would constitute such a default, in the due
         performance or observance of any term, covenant or condition contained
         in any material indenture, mortgage, deed of trust, loan agreement or
         other material agreement or instrument to which it is a party or by

         or (iii) in violation in any material respect of any law, ordinance,
         governmental rule, regulation, order, judgment or court decree to which
         it or its property or assets may be subject, except for, in the cases
         of clauses (ii) and (iii) above, such default or violation which could
         not, individually or in the aggregate, reasonably be expected to have a
         Material Adverse Effect or a material adverse effect on the ability of
         the Issuers to perform their respective obligations under the
         Transaction Documents.

               (s) Each of United, the Company and its subsidiaries possesses

         are necessary to own or lease and operate its properties or conduct its
         business as now being conducted and as described in the Offering
         Memorandum, except where the failure to possess or make the same would
         not, singularly or in the aggregate, have a Material Adverse Effect,
         and none of the Company or any of its subsidiaries has

                                      -7-




         received notification of any revocation or modification of any such
         license, certificate, authorization or permit or has any reason to
         believe that any such license, certificate, authorization or permit 
         will not be renewed in the ordinary course.

               (t) Each of United, the Company and its subsidiaries has (i)
         filed all federal, state, local and foreign income and franchise tax
         returns required to be filed through the date hereof and all such tax

         (ii) properly filed for extensions thereof, and has paid all taxes due
         thereon and all assessments received by it, except where, in the case
         of state, local and foreign tax returns, the failure to file, extend
         the due date or pay the same, in the aggregate, could not reasonably be
         expected to have a Material Adverse Effect; and no tax deficiency has
         been determined adversely to United, the Company or any of its
         subsidiaries which has had (nor does United, the Company or any of its
         subsidiaries have any knowledge of any tax deficiency which, if

         procedures) necessary for the conduct of its business as now conducted
         or proposed to be conducted as described in the Offering Memorandum;
         and the conduct of its business will not conflict in any material
         respect with, and none of United, the Company or any of its

         and its subsidiaries or (ii) are reflected in the financial statements
         or otherwise described in the Offering Memorandum (including, without

               (z) Except as described in the Offering Memorandum, no labor
         disturbance by or dispute with the employees of United, the Company or
         any of its subsidiaries exists or, to the best knowledge of the
         Company, is threatened that could reasonably be expected to have a

         the Employee Retirement Income Security Act of 1974, as amended,
         including the regulations and published interpretations thereunder
         ("ERISA"), or Section 4975 of the Internal Revenue Code of 1986, as
         amended from time to time (the "Code")) or "accumulated funding
         deficiency" (as defined in Section 302 of ERISA) or any of the events

         been waived) has occurred with respect to any employee benefit plan of
         United, the Company or any of its subsidiaries which could reasonably
         be expected to have a Material Adverse Effect; each such employee
         benefit plan is in compliance in all material respects with applicable
         law, including ERISA and the Code; each of United, the Company and its
         subsidiaries has not incurred and does not expect to incur liability
         under Title IV of ERISA with respect to the termination of, or
         withdrawal from, any pension plan for which United, the Company or any
         of its subsidiaries would have any liability; and each such pension
         plan that is intended to be qualified under Section 401(a) of the Code
         is so qualified in all material respects and nothing has occurred,
         whether by action or by failure to act, which could reasonably be
         expected to cause a Material Adverse Effect.

               (bb) To the knowledge of the Company, except as disclosed in
         the Offering Memorandum, none of United, the Company or any of its
         subsidiaries is in violation of any federal or state law or regulation
         relating to occupational safety and health or to the storage, handling
         or transportation of hazardous or toxic materials, except any such
         violation which could not, individually or in the aggregate, reasonably
         be expected to have a Material Adverse Effect, and each of United, the
         Company and its subsidiaries has received all material permits,
         licenses or other approvals required under applicable federal and state
         occupational safety and health and environmental laws and regulations
         to conduct its business. Each of United, the Company and its
         subsidiaries is in compliance with all terms and conditions of any such
         permits, licenses or approvals, except any such violation of law or
         regulation, failure to receive required permits, licenses or other
         approvals or failure to comply with the terms and conditions of such

                                      -9-




         permits, licenses or approvals which could not, individually or in the
         aggregate, reasonably be expected to have a Material Adverse Effect.

               (cc) On and immediately after the Closing Date, each of
         United, the Company and the other Guarantors (after giving effect to
         the issuance of the Securities and to the other transactions related
         thereto as described in the Offering Memorandum) will be Solvent. As
         used in this paragraph, the term "SOLVENT" means, with respect to any
         entity on a particular date, that on such date (i) the present fair
         market value (or present fair saleable value) of the assets of such
         entity is not less than the total amount required to pay the probable
         liabilities of such entity on its total existing debts and liabilities
         (including contingent liabilities) as they become absolute and matured,
         (ii) assuming the sale of the Securities as contemplated by this
         Agreement and the Offering Memorandum, such entity has not incurred
         debts or liabilities beyond its ability to pay as such debts and
         liabilities mature and (iii) such entity is not engaged in any business
         or transaction, and is not about to engage in any business or
         transaction, for which its property would constitute unreasonably small
         capital. In computing the amount of such contingent liabilities at any
         time, it is intended that such liabilities will be computed at the
         amount that, in the light of all the facts and circumstances existing
         at such time, represents the amount that can reasonably be expected to
         become an actual or matured liability.

               (dd) Except as described in the Offering Memorandum, there are
         no outstanding subscriptions, rights, warrants, calls or options to
         acquire, or instruments convertible into or exchangeable for, or
         agreements or understandings with third parties with respect to the
         sale or issuance of, any shares of capital stock of or other equity or
         other ownership interest in United, the Company or any of its
         subsidiaries.

               (ee) None of United, the Company or any of its subsidiaries
         owns any "margin securities" as that term is defined in Regulations G
         and U of the Board of Governors of the Federal Reserve System (the
         "FEDERAL RESERVE BOARD"), and none of the proceeds of the sale of the
         Securities will be used, directly or indirectly, for the purpose of
         purchasing or carrying any margin security, for the purpose of reducing
         or retiring any indebtedness which was originally incurred to purchase
         or carry any margin security or for any other purpose which might cause
         any of the Securities to be considered a "purpose credit" within the
         meanings of Regulation G, T, U or X of the Federal Reserve Board.

               (ff) None of United, the Company or any of its subsidiaries is
         a party to any contract, agreement or understanding with any person
         that would give rise to a valid claim against the Issuers or the
         Initial Purchasers for a brokerage commission, finder's fee or like
         payment in connection with the offering and sale of the Securities, the
         Exchange Securities or the Private Exchange Securities (it being
         understood that this Agreement is not such a contract, agreement or
         understanding).

               (gg) The Securities satisfy the eligibility requirements of
         Rule 144A(d)(3) under the Securities Act.

               (hh) None of United, the Company, the other Guarantors, any of
         their affiliates or any person acting on their behalf has engaged or
         will engage in any directed selling efforts (as such term is defined in
         Regulation S under the Securities Act ("REGULATION S")) with respect to
         the Securities, the Exchange Securities or the Private Exchange
         Securities,

                                     -10-




         and all such persons have complied and will comply with the
         offering restrictions requirement of Regulation S to the extent
         applicable.

               (ii) None of United, the Company, the other Guarantors, nor
         any of their affiliates has, directly or through any agent (provided
         that no representation is made as to the Initial Purchasers or any
         person acting on their behalf), sold, offered for sale, solicited
         offers to buy or otherwise negotiated in respect of, any security (as
         such term is defined in the Securities Act), which is or will be
         integrated with the sale of the Securities in a manner that would
         require registration of the Securities under the Securities Act.

               (jj) None of United, the Company, the other Guarantors or any
         of their affiliates or any other person acting on their behalf
         (provided that no representation is made as to the Initial Purchasers
         or any person acting on their behalf) has engaged, in connection with
         the offering of the Securities, in any form of general solicitation or
         general advertising within the meaning of Rule 502(c) of Regulation D
         under the Securities Act ("REGULATION D") or has solicited offers for,
         or has offered and sold, the Securities in any manner involving a
         public offering within the meaning of Section 4(2) of the Securities
         Act.

               (kk) Other than the common stock of United, there are no
         securities of United, the Company or the other Guarantors registered
         under the Securities Exchange Act of 1934, as amended (the "EXCHANGE
         ACT"), listed on a national securities exchange or quoted in a U.S.
         automated inter-dealer quotation system.

               (ll) None of United, the Company or any of the other
         Guarantors has taken, and none of them will take, directly or
         indirectly, any action prohibited by Regulation M under the Exchange
         Act in connection with the offering of the Securities, the Exchange
         Securities or the Private Exchange Securities.

               (mm) No forward-looking statement (within the meaning of
         Section 27A of the Securities Act and Section 21E of the Exchange Act)
         contained in the Preliminary Offering Memorandum or the Offering
         Memorandum has been made or reaffirmed without a reasonable basis or
         has been disclosed other than in good faith.

               (nn) The statistical and market-related data included in the
         Offering Memorandum are based on or derived from sources which the
         Company believes to be reliable.

         affiliate located in Cuba within the meaning of Florida Statutes

               (pp) Since the date as of which information is given in the
         Offering Memorandum, except as otherwise stated therein, (i) there has
         been no material adverse change, or any development involving a
         prospective material adverse change, in or affecting the condition
         (financial or otherwise), results of operations, business or prospects
         of United, the Company and its subsidiaries, taken as a whole, whether
         or not arising from transactions in the ordinary course of business,

               (b) The Initial Purchasers have advised the Company that they

         the U.S. Securities Act of 1933, as amended (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 (i) as part of their distribution

         issuance of the Securities, except in accordance with Regulation S or
         Rule 144A or any other available exemption from registration under the

such document may otherwise lawfully be issued or passed on.

               (d) The Issuers acknowledge and agree that the Initial
Purchasers may sell Securities to any affiliate of an Initial Purchaser and that
any such affiliate may sell Securities purchased by it to an Initial Purchaser.

Securities shall be made to the Company by wire or book-entry transfer of
same-day funds to such account or accounts as the Company shall specify prior to
the Closing Date or by such other means as the parties hereto shall agree prior

         counsel for the Initial Purchasers or counsel for the Company, 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

         announced that it has under surveillance or review (other than an
         announcement with positive implications of a possible upgrading), its
         rating of the Notes or any of United's or the Company's other debt
         securities.

         escalation of hostilities or a declaration by the United States of a
         national emergency or war or (iv) a material adverse change in general
         economic, political or financial conditions (or the effect of
         international conditions on the financial markets in the United States
         shall be such) the effect of which, in the case of this clause (iv),
         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 Securities on the terms and in the
         manner contemplated by this Agreement and in the Offering Memorandum
         (exclusive of any amendment or supplement thereto).

               (r) The Company shall have entered into the New Credit
         Agreement and the Initial Purchasers or their counsel shall have
         received a conformed copy thereof.

               (s) The Company shall have entered into the Receivables
         Securitization Program and the Initial Purchasers or their counsel
         shall have received a conformed copy of the principal operative
         documents related thereto.

               (t) The Initial Purchasers or their counsel shall have
         received a conformed copy of the purchase agreement and related closing
         documents for the Azerty Acquisition.

               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 reasonably
satisfactory to counsel for the Initial Purchasers.

                                     -20-





               6. TERMINATION. The obligations of the Initial Purchasers
hereunder may be terminated by the Initial Purchasers, in their absolute
discretion, by notice given to and received by the Company prior to delivery of
and payment for the Securities if, prior to that time, any of the events
described in Section 5(m), (n), (o), (p) or (q) shall have occurred and be
continuing.

               7. DEFAULTING INITIAL PURCHASERS. (a) If, on the Closing Date,
any Initial Purchaser defaults in the performance of its obligations under this
Agreement, the non-defaulting Initial Purchasers may make arrangements for the
purchase of the Securities which such defaulting Initial Purchaser agreed but
failed to purchase by other persons satisfactory to the Company and the
non-defaulting Initial Purchasers, but if no such arrangements are made within
36 hours after such default, this Agreement shall terminate without liability on
the part of the non-defaulting Initial Purchasers or the Issuers, except that
the Issuers will continue to be liable for the payment of expenses to the extent
set forth in Sections 8 and 12 and except that the provisions of Sections 9 and
10 shall not terminate and shall remain in effect. As used in this Agreement,
the term "Initial Purchasers" includes, for all purposes of this Agreement
unless the context otherwise requires, any party not listed in Schedule 1 hereto
that, pursuant to this Section 7, purchases Securities which a defaulting
Initial Purchaser agreed but failed to purchase.

               (b) Nothing contained herein shall relieve a defaulting
Initial Purchaser of any liability it may have to the Issuers or any
non-defaulting Initial Purchaser for damages caused by its default. If other
persons are obligated or agree to purchase the Securities of a defaulting
Initial Purchaser, either the non-defaulting Initial Purchasers or the Company
may postpone the Closing Date for up to seven full business days in order to
effect any changes that in the opinion of counsel for the Company or counsel for
the Initial Purchasers may be necessary in the Offering Memorandum or in any
other document or arrangement, and the Company agrees to promptly prepare any
amendment or supplement to the Offering Memorandum that effects any such
changes.

               8. REIMBURSEMENT OF INITIAL PURCHASERS' EXPENSES. If (a) this
Agreement shall have been terminated pursuant to Section 6 or 7, (b) the Issuers
shall fail to tender the Securities for delivery to the Initial Purchasers for
any reason permitted under this Agreement or (c) the Initial Purchasers shall
decline to purchase the Securities for any reason permitted under this
Agreement, the Issuers shall reimburse the Initial Purchasers for such
out-of-pocket expenses (including reasonable fees and disbursements of counsel)
as shall have been reasonably incurred by the Initial Purchasers in connection
with this Agreement and the proposed purchase and resale of the Securities. If
this Agreement is terminated pursuant to Section 7 by reason of the default of
one or more of the Initial Purchasers, the Issuers shall not be obligated to
reimburse any defaulting Initial Purchaser on account of such expenses.

               9. INDEMNIFICATION. (a) Each of the Issuers, jointly and
severally, shall indemnify and hold harmless each Initial Purchaser, its
affiliates, their respective officers, directors, employees, representatives and
agents, and each person, if any, who controls any Initial Purchaser within the
meaning of the Securities Act or the Exchange Act (collectively referred to for
purposes of this Section 9(a) and Section 10 as an Initial Purchaser), from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof (including, without limitation, any loss, claim, damage,
liability or action relating to purchases and sales of the Securities), to which
that Initial Purchaser may become subject, whether commenced or threatened,
under the Securities Act, the Exchange Act, any other federal or state statutory
law or regulation, at common law or otherwise, insofar as such loss, claim,
damage, liability or action

                                     -21-




arises out of, or is based upon, (i) any untrue statement or alleged untrue 
statement of a material fact contained in the Preliminary Offering Memorandum 
or the Offering Memorandum or in any amendment or supplement thereto or in 
any information provided by the Issuers to the holders of the Securities 
pursuant to Section 4(e) or (ii) the omission or alleged omission to state 
therein 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, and shall reimburse each Initial Purchaser 
promptly upon demand for any legal or other expenses reasonably incurred by 
that Initial Purchaser in connection with investigating or defending or 
preparing to defend against or appearing as a third party witness in 
connection with any such loss, claim, damage, liability or action as such 
expenses are incurred; PROVIDED, HOWEVER, that the Issuers 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, an untrue statement or 
alleged untrue statement in or omission or alleged omission from any of such 
documents in reliance upon and in conformity with any Initial Purchasers' 
Information; and PROVIDED, FURTHER, that with respect to any such untrue 
statement in or omission from the Preliminary Offering Memorandum, the 
indemnity agreement contained in this Section 9(a) shall not inure to the 
benefit of any such Initial Purchaser to the extent that the sale to the 
person asserting any such loss, claim, damage, liability or action was an 
initial resale by such Initial Purchaser and any such loss, claim, damage, 
liability or action of or with respect to such Initial Purchaser results from 
the fact that both (A) a copy of the Offering Memorandum was not sent or 
given to such person at or prior to the written confirmation of the sale of 
such Securities to such person and (B) the untrue statement in or omission 
from the Preliminary Offering Memorandum was corrected in the Offering 
Memorandum unless, in either case, such failure to deliver the Offering 
Memorandum was a result of non-compliance by the Issuers with Section 4(b).

               (b) Each Initial Purchaser, severally and not jointly, shall 
indemnify and hold harmless each of the Issuers, their respective affiliates, 
their respective officers, directors, employees, representatives and agents, 
and each person, if any, who controls each Issuer within the meaning of the 
Securities Act or the Exchange Act (collectively referred to for purposes of 
this Section 9(b) and Section 10 as the Issuers), from and against any loss, 
claim, damage or liability, joint or several, or any action in respect 
thereof, to which the Issuers may become subject, whether commenced or 
threatened, under the Securities Act, the Exchange Act, any other federal or 
state statutory law or regulation, at common law 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 the Preliminary Offering Memorandum or the Offering Memorandum 
or in any amendment or supplement thereto or (ii) the omission or alleged 
omission to state therein 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, 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 
any Initial Purchasers' Information, and shall reimburse the Issuers promptly 
upon demand for any legal or other expenses reasonably incurred by the 
Issuers in connection with investigating or defending or preparing to defend 
against or appearing as a third party witness in connection with any such 
loss, claim, damage, liability or action as such expenses are incurred.

               (c) Promptly after receipt by an indemnified party under this 
Section 9 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 pursuant to Section 9(a) or 9(b), notify the 
indemnifying party in writing of the claim or the commencement of that action;

                                     -22-




PROVIDED, HOWEVER, that the failure to notify the indemnifying party shall 
not relieve it from any liability which it may have under this Section 9 
except to the extent that it has been materially prejudiced (through the 
forfeiture of substantive rights or defenses) 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 9. 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 reasonably 
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 9 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 
an indemnified party shall have the right to employ its own counsel in any 
such action, but the fees, expenses and other charges of such counsel for the 
indemnified party will be at the expense of such indemnified party unless (1) 
the employment of counsel by the indemnified party has been authorized in 
writing by the indemnifying party, (2) the indemnified party has reasonably 
concluded (based upon advice of counsel to the indemnified party) that there 
may be legal defenses available to it or other indemnified parties that are 
different from or in addition to those available to the indemnifying party, 
(3) a conflict or potential conflict exists (based upon advice of counsel to 
the indemnified party) between the indemnified party and the indemnifying 
party (in which case the indemnifying party will not have the right to direct 
the defense of such action on behalf of the indemnified party) or (4) the 
indemnifying party has not in fact employed counsel reasonably satisfactory 
to the indemnified party to assume the defense of such action within a 
reasonable time after receiving notice of the commencement of the action, in 
each of which cases the reasonable fees, disbursements and other charges of 
counsel will be at the expense of the indemnifying party or parties. It is 
understood that the indemnifying party or parties shall not, in connection 
with any proceeding or related proceedings in the same jurisdiction, be 
liable for the reasonable fees, disbursements and other charges of more than 
one separate firm of attorneys (in addition to any local counsel) at any one 
time for all such indemnified party or parties. Each indemnified party, as a 
condition of the indemnity agreements contained in Sections 9(a) and 9(b), 
shall use all reasonable efforts to cooperate with the indemnifying party in 
the defense of any such action or claim. No indemnifying party shall 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 for the plaintiff in 
any such action, the indemnifying party agrees to indemnify and hold harmless 
any indemnified party from and against any loss or liability by reason of 
such settlement or judgment. No indemnifying party shall, without the prior 
written consent of the indemnified party (which consent shall not be 
unreasonably withheld), effect any settlement of any pending or threatened 
proceeding in respect of which any indemnified party is or could have been a 
party and indemnity could have been sought hereunder by such indemnified 
party unless such settlement includes an unconditional release in form and 
substance reasonably satisfactory to such indemnified party of such 
indemnified party from all liability on claims that are the subject matter of 
such proceeding.

               The obligations of the Issuers and the Initial Purchasers in 
this Section 9 and in Section 10 are in addition to any other liability that 
the Issuers or the Initial Purchasers, as the case may be, may otherwise 
have, including in respect of any breaches of representations, warranties and 
agreements made herein by any such party.

                                   -23-




               10. CONTRIBUTION. If the indemnification provided for in 
Section 9 is unavailable or insufficient to hold harmless an indemnified 
party under Section 9(a) or 9(b), 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 Issuers on the 
one hand and the Initial Purchasers on the other from the offering of the 
Securities 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 Issuers on the one hand and the Initial Purchasers on 
the other with respect to the statements or omissions that 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 Issuers on the one hand and the Initial Purchasers on the other with 
respect to such offering shall be deemed to be in the same proportion as the 
total net proceeds from the offering of the Securities purchased under this 
Agreement (before deducting expenses) received by or on behalf of the 
Issuers, on the one hand, and the total discounts and commissions received by 
the Initial Purchasers with respect to the Securities purchased under this 
Agreement, on the other, bear to the total gross proceeds from the sale of 
the Securities 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, 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 the Issuers or information supplied by the 
Issuers on the one hand or to any Initial Purchasers' Information on the 
other, the intent of the parties and their relative knowledge, access to 
information and opportunity to correct or prevent such untrue statement or 
omission. The Issuers and the Initial Purchasers agree that it would not be 
just and equitable if contributions pursuant to this Section 10 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 
that 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 10 shall be deemed to include, for purposes of this 
Section 10, any legal or other expenses reasonably incurred by such 
indemnified party in connection with investigating or defending or preparing 
to defend any such action or claim. Notwithstanding the provisions of this 
Section 10, no Initial Purchaser shall be required to contribute any amount 
in excess of the amount by which the total discounts and commissions received 
by such Initial Purchaser with respect to the Securities purchased by it 
under this Agreement exceeds the amount of any damages which such Initial 
Purchaser has otherwise paid or become liable to pay by reason of any untrue 
or alleged untrue statement or omission or alleged omission. No person guilty 
of fraudulent misrepresentation (within the meaning of Section 11(f) of the 
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 10 are several in 
proportion to their respective purchase obligations and not joint.

               11. PERSONS ENTITLED TO BENEFIT OF AGREEMENT. This Agreement 
shall inure to the benefit of and be binding upon the Initial Purchasers, the 
Issuers and their respective successors. This Agreement and the terms and 
provisions hereof are for the sole benefit of only those persons, except as 
provided in Sections 9 and 10 with respect to affiliates, officers, 
directors, employees, representatives, agents and controlling persons of the 
Issuers and the Initial Purchasers and in Section 4(e) with respect to 
holders and prospective purchasers of the

                                     -24-




Securities. Nothing in this Agreement is intended or shall be construed to 
give any person, other than the persons referred to in this Section 11, any 
legal or equitable right, remedy or claim under or in respect of this 
Agreement or any provision contained herein.

               12. EXPENSES. The Issuers agree with the Initial Purchasers to 
pay (a) the costs incident to the authorization, issuance, sale, preparation 
and delivery of the Securities 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 amendments 
or supplements thereto; (c) the costs of reproducing and distributing each of 
the Transaction Documents; (d) the costs incident to the preparation, 
printing and delivery of the certificates evidencing the Securities, 
including stamp duties and transfer taxes, if any, payable upon issuance of 
the Securities; (e) the fees and expenses of the Issuers' counsel and 
independent accountants; (f) the fees and expenses of qualifying the 
Securities under the securities laws of the several jurisdictions as provided 
in Section 4(g) and of preparing, printing and distributing Blue Sky 
Memoranda (including related reasonable fees and expenses of counsel for the 
Initial Purchasers); (g) any fees charged by rating agencies for rating the 
Securities; (h) the fees and expenses of the Trustee and any paying agent 
(including related reasonable fees and expenses of any counsel to such 
parties); (i) all expenses and application fees incurred in connection with 
the application for the inclusion of the Securities on the PORTAL Market and 
the approval of the Securities for book-entry transfer by DTC; and (j) all 
other costs and expenses incident to the performance of the obligations of 
the Issuers under this Agreement which are not otherwise specifically 
provided for in this Section 12; PROVIDED, HOWEVER, that except as provided 
in this Section 12 and Section 8, the Initial Purchasers shall pay their own 
costs and expenses (including the costs and expenses of their legal counsel 
other than as provided in clause (f) above).

               13. SURVIVAL. The respective indemnities, rights of 
contribution, representations, warranties and agreements of the Issuers and 
the Initial Purchasers contained in this Agreement or made by or on behalf of 
the Issuers or the Initial Purchasers pursuant to this Agreement or any 
certificate delivered pursuant hereto shall survive the delivery of and 
payment for the Securities and shall remain in full force and effect, 
regardless of any termination or cancellation of this Agreement or any 
investigation made by or on behalf of any of them or any of their respective 
affiliates, officers, directors, employees, representatives, agents or 
controlling persons.

               14. NOTICES, ETC. All statements, requests, notices and
