LEHMAN BROTHERS INC.
HOWARD, WEIL, LABOUISSE, FRIEDRICHS INCORPORATED
c/o Lehman Brothers Inc.
Three World Financial Center
New York, New York 10285

Ladies and Gentlemen:

         Tesoro Petroleum Corporation, a Delaware corporation (the "Company"),
proposes to sell to Lehman Brothers Inc. and Howard, Weil, Labouisse, Friedrichs
Incorporated, the several underwriters (collectively, the "Underwriters"), and
the Underwriters propose, severally and not jointly, to purchase 9,000,000
Premium Income Equity Securities, or "PIES" (the "Firm Securities"), consisting
of depositary shares, each representing one one-hundredth of a share of the
Company's 7 1/4% mandatorily convertible preferred stock (the "Mandatorily
Convertible Preferred Stock"). In addition, the Company proposes to grant to the
Underwriters an option to purchase up to an additional 1,350,000 PIES on the
terms and for the purposes set forth in Section 2 (the "Option Securities"). The
Firm Securities and the Option Securities, if purchased, are hereinafter
collectively called the "Securities." This is to confirm the agreement
concerning the purchase of the Securities from the Company by the Underwriters.

         The Securities are being issued and sold in connection with the
acquisition (the "Hawaii Acquisition") of BHP Petroleum Americas Refining Inc.
and BHP Petroleum South Pacific Inc. (together, "BHP Hawaii") and the proposed
acquisition (the "Washington Acquisition," and together with the Hawaii
Acquisition, the "Acquisitions") of Shell Anacortes Refining Company ("Shell
Washington") by the Company. Concurrently with the offering of the Securities
(the "PIES Offering"), the Company is offering 5,000,000 shares of the Company's
common stock, par value $0.16 2/3 per share (the "Common Stock"), with gross
proceeds of $79.7 million (excluding any proceeds from the exercise of
over-allotment options granted to the underwriters of the Common Stock). The
Company is also proposing to offer $300 million in aggregate principal amount of
its Senior Subordinated Notes (the "Notes"). The closing of the PIES Offering is
not conditioned upon the closings of the offerings of Common Stock (the "Common
Stock Offering") or the Notes (the




   2



"Notes Offering" and together with the Common Stock Offering and PIES Offering,
the "Offerings"), nor is the closing of any of the Offerings conditioned upon
the closing of the Washington Acquisition. The net proceeds from the Offerings,
together with borrowing under the Company's Third Amended and Restated Credit
Facility (the "Senior Credit Facility"), will be used to fund the cash purchase
price of the Washington Acquisition, to refinance the Company's Second Amended
and Restated Credit Facility (the "Interim Credit Facility") (a portion of which
was used to finance the cash purchase price of the Hawaii Acquisition), to pay
certain fees and expenses related to the Transactions (as defined below) and, to
the extent not used, for general corporate purposes (including working capital
requirements and capital expenditures).

          The (i) stock purchase agreement entered into by the Company in
connection with the Washington Acquisition (the "Washington Agreement") and the
Senior Credit Facility, (ii) the underwriting agreement entered into in
connection with the Common Stock Offering and (iii) the purchase agreement,
registration rights agreement, indenture, Notes and subsidiary guarantees
thereof entered into in connection with the Notes Offering are hereinafter
sometimes collectively referred to as the "Transaction Documents." The
Offerings, the Acquisitions and the closing of the Senior Credit Facility are
hereinafter sometimes referred to collectively as the "Transactions."

Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules

circumstances under which they were made, not misleading; and any further
documents so filed and incorporated by reference in the Prospectus when such
documents became effective or are filed with the Commission, as the case may be,

the rules and regulations of the Commission thereunder, and none of such
documents, when read together with


                                        3

   4



the other information in the Prospectus, will contain an untrue statement of a
material fact or omit to state 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.

                  (d) The Company is a corporation duly organized and validly
existing in good standing under the laws of the State of Delaware with full
corporate power and authority to own, lease and operate its properties and
conduct its business as described in the Prospectus, and is duly qualified and
registered as a foreign corporation for the transaction of business and is in
good standing in each jurisdiction in which the character of the business
conducted by it or the location of the properties owned or leased by it make
such qualification or registration necessary (except where the failure to so
qualify or register would not have a Material Adverse Effect (as defined
below)). The Company has an authorized capitalization as set forth under the
caption "Capitalization" in the Prospectus. On the date hereof and on the First
Delivery Date all of the issued and outstanding shares of capital stock of the
Company (including the shares of Common Stock to be issued in the Common Stock
Offering) have been duly authorized and will be validly issued and fully paid
and nonassessable and will conform to the description thereof contained in or
incorporated by reference in the Prospectus. As used herein, "Material Adverse
Effect" means a material adverse effect on the condition (financial or
otherwise), results of operations, business, earnings or prospects of the
Company and the Subsidiaries (as defined below), taken as a whole.

                  (e) The unissued Securities to be issued and sold by the
Company to the Underwriters have been duly and validly authorized and, when
issued and delivered against payment therefor as provided herein, will be duly
and validly issued, fully paid and nonassessable. The unissued shares of
Mandatorily Convertible Preferred Stock to be issued in exchange by the Company
to Bank of New York, as depositary with respect thereto (the "Depositary") under
the deposit agreement, dated the First Delivery Date, between the Company and
the Depositary (the "Deposit Agreement") have been duly and validly authorized
and, when issued and exchanged for depositary receipts therefor as provided in
the Deposit Agreement, will be duly and validly issued, fully paid and
nonassessable. The shares of Common Stock issuable upon the conversion of the
Mandatorily Convertible Preferred Stock, have been duly and validly authorized
and reserved for issuance, and upon such conversion, will be duly and validly
issued, fully paid and nonassessable.

                  (f) Schedule II hereto is a complete and accurate schedule of
the names of all corporations, partnerships and joint ventures (the
"Subsidiaries") which constitute "subsidiaries," as such term is defined in Rule
405 of the rules and regulations of the Commission under the Securities Act
(collectively with the rules and regulations of the Commission under the
Exchange Act, the "Rules and Regulations"). Other than the Subsidiaries listed
on Schedule II, no corporation, partnership or other entity in which the Company
has an equity interest constitutes a "subsidiary" as defined in Rule 405 of the
Rules and Regulations. Each Subsidiary is duly organized, validly existing and
in good standing in the jurisdiction of its incorporation or formation, as the
case may be, with full corporate or other power and authority to own, lease and
operate its properties and to conduct its business as described in the
Prospectus. Each Subsidiary is duly qualified and registered


                                        4

   5



as a foreign corporation or limited partnership, as the case may be, for the
transaction of business and is in good standing in each jurisdiction in which
the character of the business conducted by it or the location of the properties
owned or leased by it make such qualification or registration unnecessary, save
where the failure to so qualify or be in good standing as a foreign corporation
or limited partnership, as the case may be, would not have a Material Adverse
Effect.

                  (g) All of the issued and outstanding shares of capital stock
of each of the Subsidiaries that is a corporation have been duly authorized and
validly issued, are fully paid and nonassessable, and are owned by the Company
directly or indirectly, free and clear of any lien, adverse claim, security
interest or other encumbrance (a "Lien"), except as arising from the Interim
Credit Facility and, upon its execution, the Senior Credit Facility or as
described in the Prospectus. All outstanding equity interests in each Subsidiary
that is not a corporation have been duly authorized and validly issued and are
owned by the Company directly or indirectly, free and clear of any Lien, except
as arising from the Interim Credit Facility and, upon its execution, Senior
Credit Facility or as described in the Prospectus. Except as disclosed in the
Prospectus and as outstanding under employee benefit plans of the Company, there
are no outstanding subscriptions, rights (preemptive or other), warrants, calls,
commitments of sale or options to acquire, or instruments convertible into or
exchangeable for, nor any restriction on the voting or transfer of, any capital
stock or other equity interest of the Company or any Subsidiary;

                  (h) The Company and each of the Subsidiaries have all
requisite power and authority to execute, deliver and perform their respective
obligations under this Agreement, the Deposit Agreement and each of the
Transaction Documents, to which they may respectively be a party, and to
consummate the transactions contemplated hereby and thereby, including, without
limitation, the power and authority to issue, sell and deliver the Securities as
provided herein and therein, to consummate the exchange of the Mandatorily
Convertible Preferred Stock for depositary receipts by the Depositary under the
terms of the Deposit Agreement and to consummate the Transactions.

                  (i) This Agreement has been duly and validly authorized,
executed and delivered by the Company and constitutes a valid and binding
agreement of the Company, enforceable against the Company in accordance with its
terms, except as such enforceability may be limited by bankruptcy, insolvency,
reorganization or other similar laws affecting the enforcement of creditors'
rights generally and subject to the applicability of general principles of
equity, and except as rights to indemnity and contribution hereunder and
thereunder may be limited by Federal or state securities laws or principles of
public policy.

                  (j) The Deposit Agreement has been duly authorized by the
Company, and on the First Delivery Date will have been validly executed and
delivered by the Company. When the Deposit Agreement has been executed and
delivered by the Company, the Deposit Agreement will constitute a valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by bankruptcy,
insolvency, reorganization or other similar laws affecting the enforcement of
creditors' rights generally and to


                                        5

   6



general equity principles. The Prospectus contains and accurate summary, in all
material respects, of the terms of the Deposit Agreement.

                  (k) The Washington Agreement has been duly authorized, validly
executed and delivered by the Company. The Washington Agreement constitutes a
valid and binding agreement of the Company, enforceable against the Company in
accordance with its terms, except as such enforceability may be limited by
bankruptcy, insolvency, reorganization or other similar laws affecting the
enforcement of creditors' rights generally and to general equity principles.

                  (l) The Senior Credit Facility has been duly authorized by the
Company and, upon execution thereby, will have been validly executed and
delivered by the Company and the Subsidiaries party thereto. When the Senior
Credit Facility has been duly executed and delivered by the Company and each of
such Subsidiaries, the Senior Credit Facility will constitute a valid and
binding agreement of the Company and each of such Subsidiaries, enforceable
against the Company and each of such Subsidiaries in accordance with its terms,
except as such enforceability may be limited by bankruptcy, insolvency,
reorganization or other similar laws affecting the enforcement of creditors'
rights generally and to general equity principles. The Prospectus contains an
accurate summary, in all material respects, of the terms of the Senior Credit
Facility.

                  (m) The execution, delivery and performance of this Agreement
and the Deposit Agreement by the Company and the Transaction Documents by the
Company and the Subsidiaries party thereto, compliance by the Company and each
of such Subsidiaries with all the provisions hereof and thereof, the issuance
and sale of the Securities by the Company, the exchange of the Mandatorily
Convertible Preferred Stock for depositary receipts by the Depositary and the
consummation by the Company and such Subsidiaries of the transactions
contemplated hereby and thereby, including the Transactions and as described in
the Prospectus under the caption "Use of Proceeds," (i) will not conflict with
or result in a breach or violation of any of the terms or provisions of, or
constitute a default under, any indenture, mortgage, deed of trust, loan
agreement or other agreement or instrument to which the Company or any
Subsidiary is a party or by which the Company or any Subsidiary is bound or to
which any of the properties or assets of the Company or any Subsidiary is
subject, (ii) will not result in any violation of the provisions of the charter,
by-laws or other organizational documents of the Company or any Subsidiary or

agency or body having jurisdiction over the Company or any Subsidiary or any of
their respective properties or assets, or (iv) result in the imposition or
creation of (or the obligation to create or impose) a Lien under any agreement
or instrument to which the Company or any Subsidiary is a party or by which the
Company or any Subsidiary or their respective properties or assets is bound,
except in the case of clauses (i), (iii) and (iv) for such conflicts, breaches,
defaults, violations or Liens which individually or in the aggregate would not
result in a Material Adverse Effect. Except for such consents, approvals,
authorizations, other orders, filings, qualifications or registrations (i) as
have been obtained, (ii) as may be required under applicable state securities or
Blue Sky laws of various jurisdictions in connection with the issuance, sale and
delivery of the Securities, (iii) as may be required in connection with the
Washington Acquisition, (iv) as may


                                        6

   7



be required in the perfection of liens in connection with the consummation of
the Transactions and (v) which the failure to obtain would not result in a
Material Adverse Effect, no consent, approval, authorization, or order of or
filing, qualification or registration with, any such court or governmental
agency or body is required for the execution, delivery and performance of this
Agreement, the Deposit Agreement or the Transaction Documents by the Company and
each of the Subsidiaries party thereto, compliance by the Company and each of
the Subsidiaries party thereto with all the provisions hereof and thereof, the

Prospectus, any material 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 in the Prospectus, except losses or interferences which do
not, individually or in the aggregate, have a Material Adverse Effect; and,
since such date, there has not been any material change in the capital stock or
other equity interest or long-term debt or short-term debt of the Company or any
Subsidiaries or any change having a Material Adverse Effect, or any development
involving a prospective material adverse change, in or affecting the general
affairs, management, consolidated financial position, stockholders' equity or
results of operations of the Company and the Subsidiaries, otherwise than as set
forth or contemplated in the Prospectus; and, since such date, except as
otherwise disclosed in the Prospectus, the Company has not (i) issued or granted
any securities, other than pursuant to Company employee benefit plans or (ii)
declared or paid any dividend on its capital stock.

                  (o) The historical consolidated financial statements
(including the related notes and supporting schedules) of the Company, and to

Company and any person granting such person the right to require the Company to

Company to include such securities with any securities being registered pursuant
to any registration statement filed by the Company under the Securities Act.

                  (q) Deloitte & Touche LLP, and to the Company's knowledge,
Arthur Andersen LLP and Price Waterhouse LLP, who have certified certain
financial statements of the Company and its Subsidiaries, BHP Hawaii and Shell
Washington, respectively, whose reports are included or incorporated by
reference in the Prospectus and who have delivered the initial letters referred

Securities Act and the Rules and Regulations.

                  (r) Other than as set forth in the Prospectus, there are no
legal or governmental proceedings pending to which the Company or any Subsidiary
is a party or to which any of their respective properties or assets is subject

could materially and adversely affect the consummation by the Company of its
obligations pursuant to this Agreement, the Deposit Agreement or the Transaction
Documents; and to the Company's knowledge, no such proceedings are threatened or
contemplated by government authorities or threatened by others.

                  (s) The Company and each of the Subsidiaries has such permits,
licenses, franchises and authorizations of governmental or regulatory
authorities ("permits") as are necessary to own its respective properties and to
conduct its business in the manner described in the Prospectus subject in each
case to such qualifications as may be set forth in the Prospectus and except

to such qualifications as may be set forth in the Prospectus and except where

                  (t) The Company and each of the Subsidiaries owns or possesses
adequate rights to use all material patents, patent applications, trademarks,
service marks, trade names, trademark registrations, service mark registrations,
copyrights and licenses necessary for the conduct of their respective
businesses, except where the failure to have such permits would not have a
Material Adverse Effect, and have no reason to believe that the conduct of their
respective businesses will conflict with, and have not received any notice of
any claim of conflict with, any such rights of others.

                  (u) With the exception of producing oil and gas properties and
gas gathering properties (the "Oil and Gas Properties"), the Company and each of
the Subsidiaries has good and indefeasible title in fee simple to all real
property and good and defensible title to all personal property owned by them,
in each case free and clear of all liens, encumbrances and defects except such

the value of such property or interfere with the use made and proposed to be
made of such property by the Company and the Subsidiaries; and with the
exception of the Oil and Gas Properties, all real property, buildings and
vessels held under lease by the Company and the Subsidiaries are held by them
under valid, subsisting and enforceable leases, with such exceptions as are not
material and do not interfere with the use made and proposed to be made of such
property, buildings and vessels by the Company and the Subsidiaries.

                  (v) The Company and each of the Subsidiaries has good and
defensible title to its Oil and Gas Properties, free and clear of all liens,
encumbrances and defects, except (a) those described in the Preliminary
Prospectus and the Prospectus, (b) liens securing taxes and other governmental
charges, or claims of materialmen, mechanics and similar persons, not yet due
and payable, (c) liens and encumbrances under operating agreements, unitization
and pooling agreements, and gas sales contracts, securing payment of amounts not

industry and (d) liens, encumbrances and defects that do not in the aggregate
materially affect the value of such Oil and Gas Properties or materially
interfere with the use made or proposed to be made of such properties by the
Company or any of the Subsidiaries. Except to the extent described in the
Preliminary Prospectus and the Prospectus, the oil, gas and mineral leases, coal
methane leases, options to lease, drilling concessions or other property
interests therein held by the Company and each of the Subsidiaries reflects in
all material respects the right of the Company and its Subsidiaries, as the case
may be, to explore or receive production from the undeveloped properties
described in the Preliminary Prospectus and the Prospectus, and the Company and
each of the Subsidiaries have exercised reasonable diligence with respect to
acquiring or otherwise procuring such leases, options to lease, drilling
concessions and other property interests.

                  (w) No labor disturbance by the employees of the Company or
any of the Subsidiaries exists or, to the knowledge of the Company, is imminent
which might be expected to have a Material Adverse Effect; except as disclosed
in the Prospectus, neither the Company nor any of the Subsidiaries is party to a
collective bargaining agreement; and there are no significant unfair


                                        9

   10

or, to the best of the Company's knowledge, threatened against any of them.

                  (x) The Company and each of the Subsidiaries is in compliance
in all material respects with all presently applicable provisions of the
Employee Retirement Income Security Act of 1974, as amended, including the
regulations and published interpretations thereunder ("ERISA"); no "reportable
event" (as defined in ERISA) has occurred with respect to any "pension plan" (as
defined in ERISA) for which the Company or any of the Subsidiaries would have

                           (ii) (A) Neither the Company nor any of the
         Subsidiaries has sustained since the date of the latest quarterly
         financial statements included or incorporated by reference in the
         Preliminary Prospectus or the Prospectus any material 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 Preliminary Prospectus or the
         Prospectus and (B) since such date there has not been any material
         change in the capital stock, long-term debt or short-term debt of the
         Company or any of the Subsidiaries or any material change, or any
         development involving a prospective material adverse change, in or
         affecting the general affairs, management, financial position,
         stockholders' equity, results of operations or prospects of the Company
         and the Subsidiaries, taken as a whole, otherwise than as set forth or
         contemplated in the Preliminary Prospectus or the Prospectus; and


                                       19

   20



                           (iii) They have carefully examined the Registration
         Statement or the Prospectus and, in their opinion (A) the Registration
         Statement or the Prospectus, as of their respective dates, did not
         include any untrue statement of a material fact and did not omit to
         state any material fact necessary to make the statements therein, (in
         the case of the Prospectus, in the light of the circumstances under
         which they were made), not misleading, and (B) since the date of the
         Prospectus, no event has occurred which should have been set forth in a
         supplement or amendment to the Prospectus.

                           (iv) The Prospectus shall have been timely filed with
         the Commission in accordance with Section 5(a) of this Agreement; no
         stop order suspending the effectiveness of the Registration Statement
         or any part thereof shall have been issued and no proceeding for that
         purpose shall have been initiated or threatened by the Commission as of
         such Delivery Date; and any request of the Commission for inclusion of
         additional information in the Registration Statement or the Prospectus
         or otherwise shall have been complied with.

                  (k) (i) Neither the Company nor any of its Subsidiaries shall
have sustained since the date of the latest audited financial statements
included or incorporated by reference in the Prospectus any material 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 Prospectus and (ii) since such date there shall not have
been any material change in the capital stock, long-term debt or short-term debt
of the Company or any of its Subsidiaries or any material change, or any
development involving a prospective material change, in or affecting the general
affairs, management, consolidated financial position, stockholders' equity or
results of operations of the Company and its Subsidiaries taken as a whole,
otherwise than as set forth or contemplated in the Prospectus, the effect of
which, in any such case described in clause (i) or (ii), is, in the judgment of
the Underwriters, so material and adverse as to make it impracticable or
inadvisable to proceed with the offering or the delivery of the Securities on
the terms and in the manner contemplated in the Prospectus.

                  (l) The Company shall have entered into the Deposit Agreement.

                  (m) Subsequent to the execution and delivery of this Agreement
(i) no downgrading shall have occurred in the rating accorded the Company or any
of the Subsidiaries or any securities of the Company or any of the Subsidiaries
by any "nationally recognized statistical rating organization," as that term is
defined by the Commission for purposes of Rule 436(g)(2) of the Rules and
Regulations 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 Notes.

                  (n) The Underwriters shall have received from Andrews & Kurth
L.L.P., counsel for the Underwriters, their opinion, dated such Delivery Date,
with respect to such matters as the Underwriters may reasonably require, and the
Company shall have furnished to such counsel such


                                       20

   21



documents and information as they may reasonably request for the purpose of
enabling them to pass upon such matters.

         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 Underwriters.

SECTION  8.       Indemnification and Contribution.

                  (a) The Company shall indemnify and hold harmless each
Underwriter, its officers and employees and each person, if any, who controls
any Underwriter 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 Securities), to which that
Underwriter, 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 Prospectus,
Registration Statement or the Prospectus or in any amendment or supplement
thereto, (ii) the omission or alleged omission to state in any Preliminary
Prospectus, the Registration Statement or the Prospectus or in any amendment or
supplement thereto, any material fact required to be stated therein or necessary
to make the statements therein not misleading or (iii) any act or failure to
act, or any alleged act or failure to act, by any Underwriter in connection
with, or relating in any manner to, the Securities or the offering contemplated
hereby, and which is included as part of or referred to in any loss, claim,
damage, liability or action arising out of or based upon matters covered by
clause (i) or (ii) above (provided that the Company shall not be liable in the
case of any matter covered by this clause (iii) to the extent that it is
determined in a final judgment by a court of competent jurisdiction that such
loss, claim, damage, liability or action resulted directly from any such act or
failure to act undertaken or omitted to be taken by such Underwriter through its
gross negligence or willful misconduct), and shall reimburse each Underwriter
and each officer, employee and controlling person promptly upon demand for any
legal or other expenses reasonably incurred by that Underwriter, 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 Company 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
Prospectus, the Registration Statement or the Prospectus or in any such
amendment or supplement, in reliance upon and in conformity with the written
information furnished to the Company by or on behalf of any Underwriter
specifically for inclusion therein and described in Section 8(e); provided,
further, that with respect to any such untrue statement or omission made in the
Preliminary Prospectus, the indemnity agreement contained in this Section 8(a)
shall not enure to the benefit of the Underwriter from whom the person asserting
any such losses, claims, damages or liabilities purchased the Securities
concerned if, to the extent that such sale was an initial sale by such
Underwriter and any such loss claim, damage or liability of such Underwriter is
a result of the fact that both (A) a copy of the Prospectus was not sent


                                       21

   22



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 or omission in the
Preliminary Prospectus was corrected in the Prospectus unless, in either case,
such failure to deliver the Prospectus was a result of noncompliance by the
Company with Section 5(c) hereof. The foregoing indemnity agreement is in
addition to any liability which the Company may otherwise have to any
Underwriter or to any officer, employee or controlling person of any
Underwriter.

                  In addition to and without limitation of the Company's
obligation to indemnify Howard, Weil, Labouisse, Friedrichs Incorporated as an
Underwriter, the Company also agrees to indemnify and hold harmless the
Independent Underwriter and each person, if any, who controls the Independent
Underwriters within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act from and against any and all loss, liability, claim, damage and
expense whatsoever, as incurred, incurred as a result of the Independent
Underwriter's participation as a "qualified independent underwriter" in
connection with the PIES Offering.

                  (b) Each Underwriter, severally and not jointly, shall
indemnify and hold harmless the Company and each person, if any, who controls
the Company 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 Company, any such director, officer or employee, or any 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 Prospectus, the Registration Statement or the
Prospectus or in any amendment or supplement thereto or (ii) the omission or
alleged omission to state in any Preliminary Prospectus, the Registration
Statement or the Prospectus or in any amendment or supplement thereto, any
material fact required to be stated therein 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
Company by or on behalf of such Underwriter specifically for inclusion therein
and described in Section 8(e), and shall reimburse the Company and any such
director, officer or employee, or any such controlling person, for any legal or
other expenses reasonably incurred by the Company or any such director, officer
or employee, or any 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 Underwriter may otherwise have to the
Company or any such director, officer or employee, or any controlling person.

                  (c) Promptly after receipt by an indemnified party under this
Section 8 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 8, 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 8 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


                                       22

   23



have to an indemnified party otherwise than under this Section 8. 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 8 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
the indemnified party shall have the right to employ counsel to represent all
indemnified parties who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the indemnified parties against the
indemnifying party under this Section 8 if, (i) the employment of such counsel
shall have been authorized by the indemnifying party in connection with the
defense of such action, (ii) the indemnifying party shall not have engaged
counsel reasonably promptly to take charge of the defense of such action or
(iii) counsel for any of the indemnified parties shall have reasonably concluded
that there may be defenses available to the indemnified parties that are in
addition to or in conflict with those available to the indemnifying party, and,
in that event, the fees and expenses of such separate counsel shall be paid by
the indemnifying party; provided, further, that in connection with any
proceedings or related proceedings in the same jurisdiction, the indemnifying
party shall not be liable for the legal fees and expenses of more than one
separate firm of attorneys (in addition to any local counsel). 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 includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit or proceeding,
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.

                  (d) If the indemnification provided for in this Section 8
shall for any reason be unavailable to or insufficient to hold harmless an
indemnified party under Section 8(a) or 8(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 Company, on the one hand, and the Underwriters, 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 Company, on the one hand, and the
Underwriters on the other with respect to the statements or omissions which
resulted in such loss,


                                       23

   24



claim, damage or liability, or action in respect thereof, as well as any other
relevant equitable considerations. The relative benefits received by the
Company, on the one hand, and the Underwriters 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 the Company, on the one hand, and the
total underwriting discounts and commissions received by the Underwriters with
respect to the Securities purchased under this Agreement, on the other hand,
bear to the total gross proceeds from the offering of the Securities under this
Agreement, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault shall be determined by reference to 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
Company, on the one hand, or the Underwriters, the intent of the parties and
their relative knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Underwriters agree that
it would not be just and equitable if contributions pursuant to this Section
8(d) were to be determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take 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 8(d) shall be deemed to include, for purposes of this
Section 8(d), any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 8(d), the Underwriters
shall not be required to contribute any amount in excess of the amount by which
the total price at which the Securities sold and distributed by it was offered
to the purchasers exceeds the amount of any damages which the Underwriters have
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.

                  (e) The Underwriters severally confirm and the Company
acknowledges that the statements with respect to the offering of the Securities
set forth in the bottom paragraph on the cover page of, the legend concerning
stabilization and overallotment on the inside front cover of the Prospectus, and
the seventh, eighth, ninth and tenth paragraphs under the caption "Underwriting"
relating to stabilization and over-allotment in, the Prospectus are correct and
constitute the only information furnished in writing to the Company by or on
behalf of the Underwriters specifically for inclusion in the Prospectus.

SECTION  9.       Defaulting Underwriters.

         If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Underwriters shall be obligated to purchase the Securities which
the defaulting Underwriter agreed but failed to purchase on such Delivery Date
in the respective proportions which the number of Firm Securities set opposite
the name of each remaining non-defaulting Underwriter in Schedule I hereto bears
to the total number of Firm




                                       24

   25



Securities set opposite the names of all the remaining non-defaulting
Underwriters in Schedule I hereto; provided, however, that the remaining
non-defaulting Underwriters shall not be obligated to purchase any of the
Securities on such Delivery Date if the total number of Securities which the
defaulting Underwriter or Underwriters agreed but failed to purchase on such
date exceeds 9% of the total number of Securities to be purchased on such
Delivery Date, and any remaining non-defaulting Underwriter shall not be
obligated to purchase more than 110% of the number of Securities which it agreed
to purchase on such Delivery Date pursuant to the terms of Section 2. If the
foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or
those other underwriters satisfactory to the Underwriters who so agree, shall
have the right, but shall not be obligated, to purchase, in such proportion as
may be agreed upon among them, all the Securities to be purchased on such
Delivery Date. If the remaining Underwriters or other underwriters satisfactory
to the Underwriters do not elect to purchase the shares which the defaulting
Underwriter or Underwriters agreed but failed to purchase on such Delivery Date,
this Agreement (or, with respect to the Second Delivery Date, the obligation of
the Underwriters to purchase, and of the Company to sell, the Option Securities)
shall terminate without liability on the part of any non-defaulting Underwriter
or the Company, except that the Company will continue to be liable for the
payment of expenses to the extent set forth in Section 6. As used in this
Agreement, the term "Underwriter" includes, for all purposes of this Agreement
unless the context requires otherwise, any party not listed in Schedule I hereto
who, pursuant to this Section 9, purchases Securities which a defaulting
Underwriter agreed but failed to purchase.

         Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If other
underwriters are obligated or agree to purchase the Securities of a defaulting
or withdrawing Underwriter, either the Underwriters or the Company may postpone
the Delivery 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
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

SECTION  10.      Termination.

         The obligations of the Underwriters hereunder may be terminated by them
by notice given to and received by the Company prior to delivery of and payment
for the Securities if, prior to that time, (i) trading in securities generally
on the New York Stock Exchange or the American Stock Exchange or in the
over-the-counter market, or trading in any securities of the Company on any
exchange or in the over-the-counter market, shall have been suspended or minimum
prices shall have been established on any such exchange or such market by the
Commission, by such exchange or by any other regulatory body or governmental
authority having jurisdiction, (ii) a banking moratorium shall have been
declared by Federal or New York 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 such 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; provided, however, in the case of
(iii) and (iv) above, as to make it, in the


                                       25

   26



judgment of the Underwriters, impracticable or inadvisable to proceed with the
offering or delivery of the Securities on the terms and in the manner
contemplated in the Prospectus.

SECTION  11.      Reimbursement of Underwriters' Expenses.

         If the sale of Securities provided for herein is not consummated
because any condition to the obligations of the Underwriters set forth in
Section 7 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 the Underwriters, the Company shall
reimburse the Underwriters for the reasonable fees and expenses of its counsel
and for such other out-of-pocket expenses as shall have been incurred by it in
connection with this Agreement and the proposed purchase of the Securities, and
upon demand the Company shall pay the full amount thereof to the Underwriters.

SECTION  12.      Notices, etc.

         All statements, requests, notices and agreements hereunder shall be in
writing, and:

                  (a) if to the Underwriters, shall be delivered or sent by
mail, telex or facsimile transmission to Lehman Brothers Inc., Three World
Financial Center, New York, New York 10285, Attention: Syndicate Department
(Fax: 212-528-8822);

Prospectus, Attention: Vice President, Finance and Treasurer (Facsimile:
210-828-8600).

Any such statements, requests, notices or agreements shall take effect at the
time of receipt thereof.

SECTION  13.      Persons Entitled to Benefit of Agreement.

         This Agreement shall inure to the benefit of and be binding upon the
Underwriters, the Company, and their respective successors. This Agreement and
the terms and provisions hereof are for the sole benefit of only those persons,
except that (x) the representations, warranties, indemnities and agreements of
the Company contained in this Agreement shall also be deemed to be for the
benefit of the officers and employees of the Underwriters and the person or
persons, if any, who control the Underwriters within the meaning of Section 15
of the Securities Act and (y) the indemnity agreement of the Underwriters
contained in Section 8(b) of this Agreement shall be deemed to be for the
benefit of directors, officers and employees of the Company and any person
controlling the Company within the meaning of Section 15 of the Securities Act.
Nothing in this Agreement is intended or shall be construed to give any person,
other than the persons referred to in this Section 13, any legal or equitable
right, remedy or claim under or in respect of this Agreement or any provision
contained herein.

SECTION  14.      Survival.

         The respective indemnities, representations, warranties and agreements
of the Company and the Underwriters contained in this Agreement or made by or on
behalf of them, respectively, pursuant to this Agreement, shall survive the
delivery of and payment for the Securities and shall remain in full force and
effect, regardless of any investigation made by or on behalf of any of them or
any person controlling any of them.

SECTION  15.      Definition of "Business Day."

         For purposes of this Agreement, "business day" means any day on which
the New York Stock Exchange, Inc. is open for trading.

SECTION  16.      Governing Law.

         THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF NEW YORK.

SECTION  17.      Counterparts.

         This Agreement may be executed in one or more counterparts and, if
executed in more than one counterpart, the executed counterparts shall each be
deemed to be an original but all such counterparts shall together constitute one
and the same instrument.

SECTION  18.      Headings.

         The headings herein are inserted for convenience of reference only and
are not intended to be part of, or to affect the meaning or interpretation of,
