Ladies and Gentlemen:

          Allergan, Inc., a corporation organized under the laws of Delaware
(the "Company"), proposes to issue and sell to the several parties named in
Schedule I hereto (the "Initial Purchasers"), for whom you (the
"Representatives") are acting as representatives, $700,000,000 aggregate
principal amount of its 1.50% Convertible Senior Notes Due 2026 (the "Firm

option to purchase up to $50,000,000 additional principal amount of such Notes
to cover over-allotments (the "Option Securities" and, together with the Firm
Securities, the "Securities"). The Securities are convertible into shares of
Common Stock, par value $0.01 per share (the "Common Stock"), of the Company at
the conversion price set forth herein. The Securities are to be issued under an
indenture (the "Indenture"), to be dated as of the Closing Date, between the
Company and Wells Fargo Bank, National Association, as trustee (the "Trustee").
The Securities will have the benefit of a registration rights agreement (the
"Registration Rights Agreement"), to be dated as of the Closing Date, between
the Company and the Initial Purchasers, pursuant to which the Company will agree
to register the resale of the Securities under the Act subject to the terms and
conditions therein specified. To the extent there are no additional parties
listed on Schedule I other than you, the term Representatives as used herein
shall mean you as the Initial Purchasers, and the terms Representatives and
Initial Purchasers shall mean either the singular or plural as the context
requires. The use of the neuter in this Agreement shall include the feminine and
masculine wherever appropriate. Certain terms used herein are defined in Section
20 hereof.

          The sale of the Securities to the Initial Purchasers will be made
without registration of the Securities or the Common Stock issuable upon
conversion thereof under the Act in reliance upon exemptions from the
registration requirements of the Act.

          In connection with the sale of the Securities, the Company has
prepared a preliminary offering memorandum, dated April 5, 2006 (including any

Purchaser on the date hereof or the next succeeding day, copies of a final
offering memorandum, dated April 6, 2006 (as amended or supplemented at the
Execution Time, including any and all exhibits thereto and any information
incorporated by reference therein, the "Final Memorandum"). Each of the
Preliminary Memorandum and the Final Memorandum sets forth certain information

securities laws, the securities laws of foreign jurisdictions or, with respect
to the Registration Rights Agreement, the by-laws and rules of the NASD and the

property or assets of the Company or any of its subsidiaries pursuant to, (i)
the charter or by-laws of the Company or any of its subsidiaries; (ii) the terms

incorporated by reference in the Disclosure Package and the Final Memorandum
include assumptions that provided a reasonable basis for presenting the
significant effects directly attributable to the transactions and events

incorporated by reference in the Disclosure Package and the Final Memorandum
comply as to form in all material respects

with the applicable accounting requirements of Regulation S-X, except that the
Company would be required to provide pro forma financial statements as of
December 31, 2005 prior to the effectiveness of a Registration Statement, and
the pro forma adjustments have been properly applied to the historical amounts
in the compilation of those statements; and except for changes that are
identified or otherwise contemplated in the Disclosure Package and the Final
Memorandum including changes in the Company's or Inamed Corporation's operating
results or financial position since September 30, 2005 reflected in the
historical financial statements included or incorporated by reference in the
Disclosure Package and the Final Memorandum, at such time as the pro forma
financials are updated to reflect the pro forma financial statements as of
December 31 2005, such updated pro forma financial statements will not, when
considered as a whole, present a financial condition of the Company that is
materially less favorable than the pro forma financial statements included or
incorporated by reference in the Disclosure Package and the Final Memorandum.

          (s) No action, suit or proceeding by or before any court or
governmental agency, authority or body or any arbitrator involving the Company
or any of its subsidiaries or its or their property is pending or, to the best
knowledge of the Company, threatened that (i) could reasonably be expected to
have a material adverse effect on the Company's performance of its obligations
under this Agreement, the Indenture or the Registration Rights Agreement, or the
consummation of any of the transactions contemplated hereby or thereby or (ii)
could reasonably be expected to have a Material Adverse Effect, except as set
forth in or contemplated in the Disclosure Package and the Final Memorandum
(exclusive of any amendment or supplement thereto).

          (t) Except as disclosed in the Disclosure Package and the Final
Memorandum, the Company and its subsidiaries have good and marketable title to
all properties and assets owned by each of them, free and clear of all
mortgages, pledges, liens, charges, security interests, claims, encumbrances or
restrictions of any kind, except such as are neither material in amount nor
materially significant in relation to the business of the Company and its
subsidiaries, considered as one enterprise; all of the leases and subleases
material to the business of the Company and its subsidiaries, considered as one
enterprise, and under which the Company or any of its subsidiaries holds
properties described in the Disclosure Package and the Final Memorandum are in
full force and effect, and neither the Company nor any of its subsidiaries has
any written notice of any material claim of any sort that has been asserted by
anyone adverse to the rights of the Company or any of its subsidiaries under any
of the leases or subleases mentioned above, or affecting or questioning the
rights of the Company or any subsidiary thereof to the continued possession of
the leased or subleased premises under any such lease or sublease.

          (u) Except as disclosed in the Disclosure Package and the Final
Memorandum and except as would not have a Material Adverse Effect, neither the
Company nor any of its subsidiaries is in violation of its charter, by-laws or
other organizational documents or in default in the performance or observance of
any obligation, agreement, covenant or condition contained in any contract,
indenture, mortgage, deed of trust, loan or credit agreement, note, lease or
other agreement or instrument to which the Company or any of its subsidiaries is
a party or by which it may be bound or to which any of the property or assets of
the Company or any of its subsidiaries may be subject.

Purchasers as such Initial Purchaser is purchasing of the Firm Securities,
subject to such adjustments as you in your absolute discretion shall make to
eliminate any fractional Securities.

          3. Delivery and Payment.

          (a) Delivery of and payment for the Firm Securities and the Option
Securities (if the option provided for in Section 2(b) hereof shall have been

the Securities shall be made to the Representatives for the respective accounts
of the several Initial Purchasers against payment by the several Initial
Purchasers through the Representatives of the purchase price thereof to or upon

through the facilities of The Depository Trust Company unless the
Representatives shall otherwise instruct.

          (b) If the option provided for in Section 2(b) hereof is exercised
after the first Business Day immediately following the Closing Date, the Company
will deliver the Option Securities (at the expense of the Company) to the
Representatives on the date specified by the Representatives (which shall be
within three Business Days after exercise of said option) for the respective
accounts of the several Initial Purchasers, against payment by the several
Initial Purchasers through the Representatives of the purchase price thereof to
or upon the order of the Company by wire transfer payable in same-day funds to
the account specified by the Company. If settlement for the Option Securities
occurs after the Closing Date, the Company will deliver to the Representatives
on the settlement date for the Option Securities, and the obligation of the

     accordance with Rule 144A;

               (ii) neither it nor any person acting on its behalf has made or
     will make offers or sales of the Securities in the United States by means
     of any form of general solicitation or general advertising (within the
     meaning of Regulation D) in the United States;

               (iii) in connection with each sale pursuant to Section 4(b)(i),
     it has taken or will take reasonable steps to ensure that the purchaser of
     such Securities is aware that such sale is being made in reliance on Rule
     144A;

               (iv) any information provided by the Initial Purchasers to
     publishers of publicly available databases about the terms of the
     Securities shall include a statement that the Securities have not been
     registered under the Act and are subject to restrictions under Rule 144A
     under the Act;

     inducement to engage


                                       11

<PAGE>

     in investment activity (within the meaning of Section 21 of the FSMA)
     received by it in connection with the issue or sale of any Securities, in
     circumstances in which Section 21(1) of the Financial Services and Markets
     Act 2000 (the "FSMA") does not apply to the Company; and

               (ix) it has complied and will comply with all applicable
     provisions of the FSMA with respect to anything done by it in relation to
     the Securities in, from or otherwise involving the United Kingdom.

          5. Agreements. The Company agrees with each Initial Purchaser that:

          (a) The Company will furnish to each Initial Purchaser and to counsel
for the Initial Purchasers, without charge, during the period referred to in
Section 5(d) below, as many copies of the materials contained in the Disclosure
Package and the Final Memorandum and any amendments and supplements thereto as
they may reasonably request.

          (b) The Company will not amend or supplement the Disclosure Package or
the Final Memorandum, other than by filing documents under the Exchange Act that
are incorporated by reference therein, without the prior written consent of the
Representatives, which consent will not be unreasonably withheld; provided,
however, that, prior to the completion of the distribution of the Securities by
the Initial Purchasers (as determined by the Initial Purchasers), the Company
will not file any document under the Exchange Act that is incorporated by
reference in the Disclosure Package or the Final Memorandum unless, prior to
such proposed filing, the Company has furnished the Representatives with a copy
of such document for their review and the Representatives have not reasonably
objected to the filing of such document. The Company will promptly advise the
Representatives when any document filed under the Exchange Act that is
incorporated by reference in the Disclosure Package or the Final Memorandum
shall have been filed with the Commission.

          (c) The Company will prepare a final term sheet, containing solely a
description of final terms of the Securities and the offering thereof, in the
form approved by you and attached as Schedule II hereto.

          (d) If at any time prior to the completion of the sale of the
Securities by the Initial Purchasers (as determined by the Representatives), any
event occurs as a result of which the Disclosure Package and the Final
Memorandum, as then amended or supplemented, would include any untrue statement
of a material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were made
or in light of the circumstances then prevailing, not misleading, or if it
should be necessary to amend or supplement the Disclosure Package and the Final
Memorandum to comply with applicable law, the Company will promptly (i) notify
the Representatives of any such event; (ii) subject to the requirements of
Section 5(b), prepare an amendment or supplement that will correct such
statement or omission or effect such compliance; and (iii) supply any
supplemented or amended Disclosure Package and the Final Memorandum to the
several Initial Purchasers and counsel for the Initial Purchasers, without
charge, in such quantities as they may reasonably request.

<PAGE>

          (e) Without the prior written consent of the Representatives, the
Company has not given and will not give to any prospective purchaser of the
Securities any written information concerning the offering of the Securities
other than materials contained in the Disclosure Package, the Final Memorandum
or any other offering materials prepared by or with the prior written consent of
the Representatives.

          (f) The Company will arrange, if necessary, for the qualification of
the Securities for sale by the Initial Purchasers under the laws of such
jurisdictions as the Representatives may designate and will maintain such
qualifications in effect so long as required for the sale of the Securities;
provided that in no event shall the Company be obligated to qualify to do
business in any jurisdiction where it is not now so qualified or to take any
action that would subject it to service of process in suits, other than those
arising out of the offering or sale of the Securities, in any jurisdiction where
it is not now so subject. The Company will promptly advise the Representatives
of the receipt by the Company of any notification with respect to the suspension
of the qualification of the Securities for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purpose.

          (g) The Company will not, and will not permit any of its Affiliates
to, resell any Securities or shares of Common Stock issued upon conversion
thereof that have been acquired by any of them.

          (h) None of the Company, its Affiliates, or any person acting on its
or their behalf (other than the Initial Purchasers) will, directly or
indirectly, make offers or sales of any security, or solicit offers to buy any
security, under circumstances that would require the registration of the
Securities or Common Stock issuable upon conversion thereof under the Act.

          (i) None of the Company, its Affiliates, or any person acting on its
or their behalf (other than the Initial Purchasers) will engage in any form of
general solicitation or general advertising (within the meaning of Regulation D)
in connection with any offer or sale of the Securities in the United States.

          (j) So long as any of the Securities or the Common Stock issuable upon
the conversion thereof are "restricted securities" within the meaning of Rule
144(a)(3) under the Act the Company will, during any period in which it is not
subject to and in compliance with Section 13 or 15(d) of the Exchange Act,
provide to each holder of such restricted securities and to each prospective
purchaser (as designated by such holder) of such restricted securities, upon the
request of such holder or prospective purchaser, any information required to be
provided by Rule 144A(d)(4) under the Act. This covenant is intended to be for
the benefit of the holders, and the prospective purchasers designated by such
holders, from time to time of such restricted securities.

          (k) Any information provided by the Company to publishers of publicly
available databases about the terms of the Securities shall include a statement
that the Securities have not been registered under the Act and are subject to
restrictions under Rule 144A under the Act.


                                       13

best efforts to permit the Securities to be eligible for clearance and
settlement through The Depository Trust Company.

long as any Securities are outstanding and convertible, free of pre-emptive
rights, the full number of shares of Common Stock issuable upon conversion of
the Securities.

Execution Time, without the prior written consent Banc of America Securities and
Citigroup, directly or indirectly, offer, sell or contract to sell, or otherwise
dispose of (or enter into any transaction which is designed to, or might
reasonably be expected to, result in the disposition (whether by actual
disposition or effective economic disposition due to cash settlement or
otherwise) by the Company or any Affiliate of the Company or any person in
privity with the Company or any Affiliate of the Company), or establish or
increase a put equivalent position or liquidate or decrease a call equivalent
position within the meaning of Section 16 of the Exchange Act in respect of, any
shares of capital stock of the Company or any securities convertible into, or
exercisable or exchangeable for, shares of capital stock of the Company (other
than the Securities), or publicly announce an intention to effect any such
transaction; provided, however, that (i) the Company may issue and sell Common
Stock or securities convertible into or exchangeable for Common Stock pursuant
to any employee stock option plan, stock ownership plan, deferred compensation
plan, stock bonus plan, dividend reinvestment plan or other arrangement
described in the Disclosure Package and the Final Memorandum of the Company and
in effect at the Execution Time, (ii) the Company may issue Common Stock
issuable upon the conversion of securities or the exercise of options or
warrants outstanding at the Execution Time, and (iii) the Company may issue and
sell Common Stock or securities convertible into or exchangable for Common Stock

          (o) The Company will not take, directly or indirectly, any action

manipulation of the price of any security of the Company to facilitate the sale

          (p) The Company agrees to pay the costs and expenses relating to the
following matters: (i) the preparation of the Registration Rights Agreement and
the preparation, printing or reproduction of the materials contained in the
Disclosure Package and the Final Memorandum and each amendment or supplement to
either of them; (ii) the printing (or reproduction) and delivery (including
postage, air freight charges and charges for counting and packaging) of such
copies of the materials contained in the Disclosure Package and the Final
Memorandum, and all amendments or supplements to either of them, as may, in each
case, be reasonably requested for use in connection with the offering and sale
of the Securities; (iii) the preparation, printing, authentication, issuance and
delivery of certificates for the Securities; (iv) any stamp or transfer taxes in
connection with the original issuance and sale of the Securities; (v) the
printing (or reproduction) and delivery of this Agreement, any blue sky

delivered in connection with the offering of the Securities; (vi) any
registration or qualification of the Securities for offer and sale


                                       14

<PAGE>

under the securities or blue sky laws of the several states, and any other
jurisdictions specified pursuant to Section 5(f) (including filing fees and the
reasonable fees and expenses of counsel for the Initial Purchasers relating to
such registration and qualification); (vii) the transportation and other
expenses incurred by or on behalf of Company representatives in connection with
presentations to prospective purchasers of the Securities; (viii) the fees and
expenses of the Company's accountants and the fees and expenses of counsel

and expenses incident to the performance by the Company of their obligations
hereunder. Except as provided in this Section 5(p) and Section 7, the Initial
Purchasers shall pay their own expenses, including the fees and disbursements of

          (q) Between the date hereof and the Closing Date, the Company will not

          (r) The Company will, for a period of twelve months following the
Execution Time, furnish to the Representatives upon request (i) all reports or
other communications (financial or other) generally made available to
stockholders, and deliver to the Representatives as soon as they are available,
copies of any reports and financial statements furnished to or filed with the
Commission or any securities exchange on which any class of securities of the
Company is listed and (ii) such additional information concerning the business
and financial condition of the Company as the Representatives may from time to
time reasonably request (such statements to be on a consolidated basis to the
extent the accounts of the Company and its subsidiaries are consolidated in
reports furnished to stockholders).

          (s) The Company will not take any action or omit to take any action
(such as issuing any press release relating to any Securities without an
appropriate legend) which may result in the loss by any of the Initial Purchases
of the ability to rely on any stabilization safe harbor provided by the
Financial Services Authority under the FSMA.

          (t) The Company will comply in all material respects with all
applicable securities and other laws, rules, and regulations, including, without
limitation, the Sarbanes-Oxley Act, and use its best efforts to cause the
Company's directors and officers, in their capacities as such, to comply in all
material respects with such laws, rules and regulations, including, without
limitation, the provisions of the Sarbanes-Oxley Act.

          6. Conditions to the Obligations of the Initial Purchasers. The
obligations of the Initial Purchasers to purchase the Firm Securities and the
Option Securities, as the case may be, shall be subject to the accuracy of the
representations and warranties of the Company contained herein at the Execution
Time, the Closing Date and any settlement date pursuant to Section 3 hereof, to
the accuracy of the statements of the Company made in any certificates pursuant
to the provisions hereof, to the performance by the Company of its obligations

                                       15
<PAGE>

          (b) The Representatives shall have received from Cleary Gottlieb Steen
& Hamilton LLP, counsel for the Initial Purchasers, such opinion or opinions,
dated the Closing Date and addressed to the Representatives, with respect to the
issuance and sale of the Securities, the Indenture, the Registration Rights
Agreement, the Disclosure Package, the Final Memorandum (as amended or
supplemented at the Closing Date) and other related matters as the
Representatives may reasonably require, and the Company shall have furnished to
such counsel such documents as they reasonably request for the purpose of
enabling them to pass upon such matters.

          (c) The Company shall have furnished to the Representatives a
certificate of the Company, signed by (i) the President or the Chief Executive
Officer and (ii) the principal financial officer or the principal accounting
officer of the Company, dated the Closing Date, to the effect that the signers
of such certificate have carefully examined the Disclosure Package and the Final
Memorandum, any amendments or supplements thereto, and this Agreement and that:

               (i) the representations and warranties of the Company in this
     Agreement are true and correct on and as of the Closing Date with the same
     effect as if made on the Closing Date, and the Company has complied with
     all the agreements and satisfied all the conditions on its part to be
     performed or satisfied hereunder at or prior to the Closing Date; and

               (ii) since the date of the most recent financial statements
     included or incorporated by reference in the Disclosure Package and the
     Final Memorandum (exclusive of any amendment or supplement thereto), there
     has been no material adverse change in the condition (financial or
     otherwise), prospects, earnings, business or properties of the Company and
     its subsidiaries, taken as a whole, whether or not arising from
     transactions in the ordinary course of business, except as set forth in or
     contemplated in the Disclosure Package and the Final Memorandum (exclusive
     of any amendment or supplement thereto).

          (d) At the Execution Time, the Company shall have requested and caused
E&Y to furnish to the Representatives a "comfort" letter, dated as of the
Execution Time and substantially in the form attached hereto as Exhibit B, and
at the Closing Time, the Company shall have requested and caused E&Y to furnish
to the Representatives a "bring-down comfort" letter, dated as of the Closing
Date, reaffirming the statements made in the "comfort" letter, except that the
specified date referred to shall be a date not more than three business days
prior to the Closing Date.

          (g) Subsequent to the Execution Time or, if earlier, the dates as of

supplement thereto), there shall not have been any change in the condition

Company and its subsidiaries taken as a whole, whether or not arising from
transactions in the ordinary course of business, except as set forth in or
contemplated in the Disclosure Package and the Final Memorandum (exclusive of
any amendment or supplement thereto), the effect of which is, in the judgment of
the Representatives, so material and adverse as to make it impractical or
inadvisable to proceed with the offering or delivery of the Securities as

any amendment or supplement thereto).

          (h) The Securities shall have been designated as PORTAL-eligible

Purchasers hereunder may be cancelled at, or at any time prior to, the Closing
Date by the Representatives. Notice of such cancellation shall be given to the
Company in writing or by telephone or facsimile confirmed in writing.


                                       17

<PAGE>

          The documents required to be delivered by this Section 6 will be
delivered at the office of counsel for the Initial Purchasers, at Cleary
Gottlieb Steen & Hamilton LLP, One Liberty Plaza, New York, New York 10006, on
the Closing Date.

          7. Reimbursement of Expenses. If the sale of the Securities provided
for herein is not consummated because any condition to the obligations of the
Initial Purchasers set forth in Section 6 hereof is not satisfied, because of
any termination pursuant to Section 10 hereof or because of any refusal,
inability or failure on the part of the Company to perform any agreement herein
or comply with any provision hereof other than by reason of a default by any of
the Initial Purchasers, the Company will reimburse the Initial Purchasers
severally through Citigroup Global Markets Inc. on demand for all out-of-pocket
expenses (including reasonable fees and disbursements of counsel) that shall
have been incurred by them in connection with the proposed purchase and sale of
the Securities.

          8. Indemnification and Contribution.

          (a) The Company agrees to indemnify and hold harmless each Initial
Purchaser, the directors and officers of each Initial Purchaser and each person
who controls any Initial Purchaser within the meaning of either the Act or the
Exchange Act against any and all losses, claims, damages or liabilities, joint
or several, to which they or any of them may become subject under the Act, the
Exchange Act or other U.S. federal or state statutory law or regulation, at
common law or otherwise, insofar as such losses, claims, damages or liabilities
(or actions in respect thereof) arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in the
Disclosure Package, the Final Memorandum, any Issuer Written Information or any
other written information used by or on behalf of the Company in connection with
the offer or sale of the Securities, or in any amendment or supplement thereto,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, and agrees to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by it in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company will not be liable in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon any such untrue statement or alleged untrue
statement or omission or alleged omission made in the Preliminary Memorandum or
the Final Memorandum, or in any amendment thereof or supplement thereto, in
reliance upon and in conformity with written information furnished to the
Company by or on behalf of any Initial Purchaser through the Representatives
specifically for inclusion therein. This indemnity agreement will be in addition
to any liability that the Company may otherwise have.

          (b) Each Initial Purchaser severally, and not jointly, agrees to
indemnify and hold harmless the Company, each of its directors, each of its
officers, and each person who controls the Company within the meaning of either
the Act or the Exchange Act, to the same extent as the foregoing indemnity from
the Company to each Initial Purchaser, but only with reference to written
information relating to such Initial Purchaser furnished to the Company by or on
behalf of such Initial Purchaser through the Representatives specifically for
inclusion in the Preliminary Memorandum or the Final Memorandum or in any
amendment or supplement thereto. This indemnity agreement will be in addition to
any liability that any Initial Purchaser


                                       18

<PAGE>

may otherwise have. The Company acknowledges that (i) the statements set forth
in the last paragraph of the cover page regarding delivery of the Securities and
(ii), under the heading "Plan of Distribution," the fifth and eighth paragraphs
and the fifth and sixth sentences of the seventh paragraph related to compliance
by the Initial Purchasers with applicable laws, stabilization and syndicate
covering transactions and market-making transactions in the Preliminary
Memorandum and the Final Memorandum constitute the only information furnished in
writing by or on behalf of the Initial Purchasers for inclusion in the
Preliminary Memorandum or the Final Memorandum or in any amendment or supplement
thereto.

          (c) Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the failure so to notify the indemnifying party (i) will not relieve it from
liability under paragraph (a) or (b) above unless and to the extent it did not
otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any
event, relieve the indemnifying party from any obligations to any indemnified
party other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel (including
local counsel) of the indemnifying party's choice at the indemnifying party's
expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel,
other than local counsel if not appointed by the indemnifying party, retained by
the indemnified party or parties except as set forth below); provided, however,
that such counsel shall be satisfactory to the indemnified party. It is
understood, however, that the Company shall, 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 circumstances, be
liable for the reasonable fees and expenses of only one separate firm of
attorneys (in addition to any local counsel) at any time for all such Initial
Purchasers and controlling persons, which firm shall be designated in writing by
the Representatives. Notwithstanding the indemnifying party's election to
appoint counsel (including local counsel) to represent the indemnified party in
an action, the indemnified party shall have the right to employ separate counsel
(including local counsel), and the indemnifying party shall bear the reasonable
fees, costs and expenses of such separate counsel if (i) the use of counsel
chosen by the indemnifying party to represent the indemnified party would
present such counsel with a conflict of interest; (ii) the actual or potential
defendants in, or targets of, any such action include both the indemnified party
and the indemnifying party and the indemnified party shall have reasonably
concluded that there may be legal defenses available to it and/or other
indemnified parties that are different from or additional to those available to
the indemnifying party; (iii) the indemnifying party shall not have employed
counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of the institution of such action; or (iv)
the indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party. An indemnifying party will
not, without the prior written consent of the indemnified parties, 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)


                                       19

<PAGE>

unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

          (d) In the event that the indemnity provided in paragraph (a) or (b)
of this Section 8 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and the Initial Purchasers
severally agree, in lieu of or supplemental to, respectively, indemnifying such
indemnified party thereunder, to contribute to the amount paid or payable by
such indemnified party as a result of the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in connection
with investigating or defending any loss, claim, damage, liability or action)
(collectively "Losses") to which the Company and one or more of the Initial
Purchasers may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and by the Initial
Purchasers on the other from the offering of the Securities; provided, however,
that in no case shall any Initial Purchaser be responsible for any amount in
excess of the purchase discount or commission applicable to the Securities
purchased by such Initial Purchaser hereunder. If the allocation provided by the
immediately preceding sentence is unavailable for any reason, the Company and
the Initial Purchasers severally shall contribute to the aggregate Losses in
such proportion as is appropriate to reflect not only such relative benefits but
also the relative fault of the Company on the one hand and the Initial
Purchasers on the other in connection with the statements or omissions that
resulted in such Losses, as well as any other relevant equitable considerations.
Benefits received by the Company shall be deemed to be equal to the total net
proceeds from the offering (before deducting expenses, but after deducting total
discounts and commissions received by the Initial Purchasers) received by it,
and benefits received by the Initial Purchasers shall be deemed to be equal to
the total purchase discounts and commissions. Relative fault shall be determined
by reference to, among other things, whether any untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information provided by the Company on the one hand or
the Initial Purchasers 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 Company and the Initial Purchasers agree
that it would not be just and equitable if contribution were determined by pro
rata allocation or any other method of allocation that does not take account of
the equitable considerations referred to above. Notwithstanding the provisions
of this paragraph (d), no person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. For purposes
of this Section 8, each person who controls an Initial Purchaser within the
meaning of either the Act or the Exchange Act and each director and officer of
an Initial Purchaser shall have the same rights to contribution as such Initial
Purchaser, and each person who controls the Company within the meaning of either
the Act or the Exchange Act and each officer and director of the Company shall
have the same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

          9. Default by an Initial Purchaser. If any one or more Initial
Purchasers shall fail to purchase and pay for any of the Securities agreed to be
purchased by such Initial Purchaser hereunder and such failure to purchase shall
constitute a default in the performance of its or their obligations under this
Agreement, the remaining Initial Purchasers shall be obligated severally to take
up and pay for (in the respective proportions which the principal amount of
Securities set forth opposite their names in Schedule I hereto bears to the
aggregate principal


                                       20

<PAGE>

amount of Securities set forth opposite the names of all the remaining Initial
Purchasers) the Securities which the defaulting Initial Purchaser or Initial
Purchasers agreed but failed to purchase; provided, however, that in the event
that the aggregate principal amount of Securities which the defaulting Initial
Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10%
of the aggregate principal amount of Securities set forth in Schedule I hereto,
the remaining Initial Purchasers shall have the right to purchase all, but shall
not be under any obligation to purchase any, of the Securities, and if such
nondefaulting Initial Purchasers do not purchase all the Securities, this
Agreement will terminate without liability to any nondefaulting Initial
Purchaser or the Company. In the event of a default by any Initial Purchaser as
set forth in this Section 9, the Closing Date shall be postponed for such
period, not exceeding five Business Days, as the Representatives shall determine
in order that the required changes in the Final Memorandum or in any other
documents or arrangements may be effected. Nothing contained in this Agreement
shall relieve any defaulting Initial Purchaser of its liability, if any, to the
Company or any nondefaulting Initial Purchaser for damages occasioned by its
default hereunder.

          10. Termination. This Agreement shall be subject to termination by the
Representatives by notice to the Company prior to delivery of, and payment for,
the Securities, if at any time prior to such delivery and payment (i) trading in
the Company's Common Stock shall have been suspended by the Commission or the
New York Stock Exchange or trading in securities generally on the New York Stock
Exchange shall have been suspended or limited or minimum prices shall have been
established on such exchange; (ii) a banking moratorium shall have been declared
either by U.S. federal or New York State authorities; or (iii) there shall have
occurred any outbreak or escalation of hostilities, declaration by the United
States of a national emergency or war or other calamity or crisis the effect of
which on financial markets is such as to make it, in the sole judgment of the
Representatives, impractical or inadvisable to proceed with the offering or
delivery of the Securities as contemplated in the Disclosure Package and the
Final Memorandum (exclusive of any amendment or supplement thereto).

          11. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and of the Initial Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of the Initial Purchasers or the Company
or any of the indemnified persons referred to in Section 8 hereof, and will
survive delivery of and payment for the Securities. The provisions of Sections
5(p), 7 and 8 hereof shall survive the termination or cancellation of this
Agreement.

          12. Notices. All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Representatives, will be mailed,
delivered or telefaxed to (i) the Citigroup General Counsel (fax no.: (212)

          13. Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the
indemnified persons referred to in Section 8 hereof, and, except as expressly
set forth in Section 5(j) hereof, no other person will have any right or
obligation hereunder.

transactions contemplated hereby.

          17. No Fiduciary Duty. The Company hereby acknowledges that (a) the
purchase and sale of the Securities pursuant to this Agreement is an
arm's-length commercial transaction between the Company, on the one hand, and
the Initial Purchasers and any affiliate through which they may be acting, on
the other, (b) the Initial Purchasers are acting as principal and not as an
agent or fiduciary of the Company and (c) the Company's engagement of the
Initial Purchasers in connection with the offering and the process leading up to

Furthermore, the Company agrees that it is solely responsible for making its own
judgments in connection with the offering (irrespective of whether any of the
Initial Purchasers has advised or is currently advising the Company on related
or other matters). The Company agrees that it will not claim that the Initial
Purchasers have rendered advisory services of any nature or respect, or owe an
agency, fiduciary or similar duty to the Company, in connection with such
transaction or the process leading thereto.

          18. Counterparts. This Agreement may be signed in one or more
