         December 9, 2003
BANC OF AMERICA SECURITIES LLC
9 West 57th Street
New York, NY 10019
     As Representative of the several Underwriters listed on Schedule A


Ladies and Gentlemen:

         Introductory. Unit Corporation, a Delaware corporation (the "COMPANY"),
proposes to issue and sell to the several underwriters named in Schedule A (the
"Underwriters") an aggregate of 2,000,000 shares (the "FIRM COMMON SHARES") of
its Common Stock, par value $.20 per share (the "COMMON STOCK"). In addition,
the Company has granted to the Underwriters an option to purchase up to an
additional 300,000 shares (the "OPTIONAL COMMON SHARES") of Common Stock, as
provided in Section 2. The Firm Common Shares and, if and to the extent such
option is exercised, the Optional Common Shares are collectively called the
"COMMON SHARES". Banc of America Securities LLC ("BAS") has agreed to act as
representative of the several Underwriters (in such capacity, the
"REPRESENTATIVE") in connection with the offering and sale of the Common Shares.

         The Company has prepared and filed with the Securities and Exchange
Commission (the "COMMISSION") a registration statement on Form S-3 (File No.
333-104165) for the registration of Common Stock (including the Common Shares),
preferred stock, debt securities, purchase contracts, units and warrants of the
Company under the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder (collectively, the "SECURITIES ACT"), and the
offering thereof from time to time in accordance with Rule 415 under the
Securities Act. Such registration statement has been declared effective by the
Commission. Such registration statement, as so amended, if applicable, including
the financial statements, exhibits and schedules thereto, and including all
documents incorporated by reference therein pursuant to Item 12 of Form S-3,
prior to the execution of this Agreement, is called the "REGISTRATION
STATEMENT". The final prospectus and the final prospectus supplement relating to
the offering of the Common Shares, in the form first furnished to the
Underwriters by the Company for use in connection with the offering of the
Common Shares, including all documents incorporated by reference therein
pursuant to Item 12 of Form S-3, prior to the execution of this Agreement, is
called the "PROSPECTUS". A "PRELIMINARY PROSPECTUS" shall be deemed to refer to
any prospectus that omitted information to be included upon pricing in a form of
prospectus filed with the Commission pursuant to Rule 424(b) under the
Securities Act and was used prior to the execution and delivery of this
Agreement. All references in this Agreement to the Registration Statement, a
preliminary prospectus, the Prospectus or any amendments or supplements to any
of the foregoing, shall include any copy thereof filed with the Commission
pursuant to its Electronic Data Gathering, Analysis and Retrieval System
("EDGAR"). All references in this Agreement to financial statements and
schedules and other information which is "CONTAINED,"





"INCLUDED" or "STATED" in the Registration Statement or the Prospectus (and all
other references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is or is deemed
to be incorporated by reference in the Registration Statement or the Prospectus,
as the case may be; and all references in this Agreement to amendments or
supplements to the Registration Statement or the Prospectus shall be deemed to
mean and include the filing of any document under the Exchange Act which is or
is deemed to be incorporated by reference in the Registration Statement or the
Prospectus, as the case may be.

         The Company hereby confirms its agreements with the Underwriters as
follows:

         SECTION 1. Representations and Warranties of the Company.

         Representations and Warranties of the Company. The Company hereby
represents, warrants and covenants to each Underwriter as follows:

         (a) Compliance with Registration Requirements. The Company meets the
requirements for use of Form S-3 under the Securities Act. The Registration
Statement has been declared effective by the Commission under the Securities
Act. No stop order suspending the effectiveness of the Registration Statement is
in effect and no proceedings for such purpose have been instituted or are
pending or, to the knowledge of the Company, have been threatened by the
Commission.

         Each preliminary prospectus and the prospectus filed as part of the
Registration Statement as originally filed or as part of any amendment thereto,
or filed pursuant to Rule 424 under the Securities Act, complied when so filed
in all material respects with the Securities Act and each preliminary prospectus
and the Prospectus delivered to the Underwriters for use in connection with the
offer and sale of the Common Shares will, at the time of such delivery, be
identical to any copies filed by electronic transmission pursuant to EDGAR
(except as may be permitted by Regulation S-T under the Securities Act). The
Registration Statement and any post-effective amendment thereto, at the time it
became effective and at all subsequent times through the end of the Prospectus
Delivery Period (as hereinafter defined), complied and will comply in all
material respects with the Securities Act and did not and will not contain any
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 not misleading.
The Prospectus, as amended or supplemented, as of its date and at all subsequent
times through the end of the Prospectus Delivery Period, did not and will not
contain any untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The representations
and warranties set forth in the two immediately preceding sentences do not apply
to statements in or omissions from the Registration Statement, or any
post-effective amendment thereto, or the Prospectus, or any amendments or
supplements thereto, made in reliance upon and in conformity with information
relating to any Underwriter furnished to the Company in writing by or on behalf
of the Representative expressly for use therein. There are no contracts or other
documents required to be described in the Prospectus or to be filed as exhibits
to the Registration Statement which have not been described or filed as
required.



                                       2


         (b) Offering Materials Furnished to Underwriters. The Company has, to
the extent requested, delivered to the Representative one complete manually
signed copy of the Registration Statement and of each consent and certificate of
experts filed as a part thereof, and conformed copies of the Registration
Statement (without exhibits) and preliminary prospectuses and the Prospectus, as
amended or supplemented, in such quantities and at such places as the
Representative has reasonably requested for each of the Underwriters.

         (c) Distribution of Offering Material By the Company. The Company has
not distributed and will not distribute, prior to the later of the Second
Closing Date (as defined below) and the completion of the Underwriters'
distribution of the Common Shares, any offering material in connection with the
offering and sale of the Common Shares other than a preliminary prospectus, the
Prospectus or the Registration Statement.

         (d) The Underwriting Agreement. This Agreement has been duly
authorized, executed and delivered by, and is a valid and binding agreement of,
the Company, enforceable in accordance with its terms, except as rights to
indemnification hereunder may be limited by applicable law and except as the
enforcement hereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles.

         (e) Authorization of the Common Shares. The Common Shares to be
purchased by the Underwriters from the Company have been duly authorized for
issuance and sale pursuant to this Agreement and, when issued and delivered by
the Company pursuant to this Agreement, will be validly issued, fully paid and
nonassessable.

         (f) No Applicable Registration or Other Similar Rights. There are no
persons with registration or other similar rights to have any equity or debt
securities registered for sale under the Registration Statement or included in
the offering contemplated by this Agreement, except for such rights as have been
duly waived.

         (g) No Material Adverse Change. Except as otherwise disclosed in the
Prospectus, subsequent to the respective dates as of which information is given
in the Prospectus: (i) there has been no material adverse change, or any
development that could reasonably be expected to result in a material adverse
change, in the condition, financial or otherwise, or in the earnings, business,
operations or prospects, whether or not arising from transactions in the
ordinary course of business, of the Company and its subsidiaries, considered as
one entity (any such change is called a "MATERIAL ADVERSE CHANGE"); (ii) the
Company and its subsidiaries, considered as one entity, have not incurred any
material liability or obligation, indirect, direct or contingent, not in the
ordinary course of business nor entered into any material transaction or
agreement not in the ordinary course of business; and (iii) there has been no
dividend or distribution of any kind declared, paid or made by the Company or,
except for dividends paid to the Company or other subsidiaries, any of its
subsidiaries on any class of capital stock or repurchase or redemption by the
Company or any of its subsidiaries of any class of capital stock.

         (h) Independent Accountants. PricewaterhouseCoopers LLP, who have
expressed their opinion with respect to the financial statements (which term as
used in this Agreement includes the related notes thereto) and supporting
schedules filed with the Commission as a part of the



                                       3


Registration Statement and included in the Prospectus, are independent public or
certified public accountants as required by the Securities Act and the Exchange
Act.

         (i) Preparation of the Financial Statements. The financial statements
filed with the Commission as a part of the Registration Statement and included
in the Prospectus present fairly the consolidated financial position of the
Company and its subsidiaries as of and at the dates indicated and the results of
their operations and cash flows for the periods specified. The supporting
schedules included in the Registration Statement present fairly the information
required to be stated therein. Such financial statements and supporting
schedules have been prepared in conformity with generally accepted accounting
principles as applied in the United States applied on a consistent basis
throughout the periods involved, except as may be expressly stated in the
related notes thereto. No other financial statements or supporting schedules are
required to be included in the Registration Statement. The financial data set
forth in the Prospectus under the captions "Prospectus Summary--Summary
Consolidated Financial, Operating and Segment Data", "Selected Financial Data"
and "Capitalization" fairly present the information set forth therein on a basis
consistent with that of the audited financial statements contained in the
Registration Statement.

         (j) Incorporation and Good Standing of the Company and its
Subsidiaries. Each of the Company and its subsidiaries has been duly
incorporated and is validly existing as a corporation in good standing under the
laws of the jurisdiction of its incorporation and has corporate power and
authority to own, lease and operate its properties and to conduct its business
as described in the Prospectus and, in the case of the Company, to enter into
and perform its obligations under this Agreement. Each of the Company and each
subsidiary is duly qualified as a foreign corporation to transact business and
is in good standing in each jurisdiction in which such qualification is
required, whether by reason of the ownership or leasing of property or the
conduct of business, except for such jurisdictions where the failure to so
qualify or to be in good standing would not, individually or in the aggregate,
result in a Material Adverse Change. All of the issued and outstanding capital
stock of each subsidiary has been duly authorized and validly issued, is fully
paid and nonassessable and is owned by the Company, directly or through
subsidiaries, free and clear of any security interest, mortgage, pledge, lien,
encumbrance or claim.

         (k) Capitalization and Other Capital Stock Matters. The authorized,
issued and outstanding capital stock of the Company is as set forth in the
Prospectus under the caption "CAPITALIZATION" (other than for subsequent
issuances, if any, pursuant to employee benefit plans described in the
Prospectus or upon exercise of outstanding options or warrants described in the
Prospectus). The Common Stock (including the Common Shares) conforms in all
material respects to the description thereof contained in the Prospectus. All of
the issued and outstanding shares of Common Stock have been duly authorized and
validly issued, are fully paid and nonassessable and have been issued in
compliance with federal and state securities laws. None of the outstanding
shares of Common Stock were issued in violation of any preemptive rights, rights
of first refusal or other similar rights to subscribe for or purchase securities
of the Company. There are no authorized or outstanding options, warrants,
preemptive rights, rights of first refusal or other rights to purchase, or
equity or debt securities convertible into or exchangeable or exercisable for,
any capital stock of the Company or any of its subsidiaries other than those
accurately described in the Prospectus. The description of the Company's stock



                                       4


option, stock bonus and other stock plans or arrangements, and the options or
other rights granted thereunder, set forth in the Prospectus accurately and
fairly presents the information required to be shown with respect to such plans,
arrangements, options and rights.

         (l) Non-Contravention of Existing Instruments; No Further
Authorizations or Approvals Required. Neither the Company nor any of its
subsidiaries is in violation of its charter or by-laws or is in default (or,
with the giving of notice or lapse of time, would be in default) ("DEFAULT")
under any indenture, mortgage, loan or credit agreement, note, contract,
franchise, lease or other instrument to which the Company or any of its
subsidiaries is a party or by which it or any of them may be bound (including,
without limitation, the Loan Agreement, dated as of July 24, 2001, by and among
(1) the Company, Mountain Front Pipeline Company, Inc., Unit Drilling Company,
Unit Petroleum Company, Petroleum Supply Company, Unit Energy Canada Inc., as
borrowers, (2) Bank of Oklahoma, National Association, Bank of America, N.A.,
Local Oklahoma Bank, N.A., UMB Bank, N.A. as lenders, and (3) Bank of Oklahoma,
National Association, as agent), or to which any of the property or assets of
the Company or any of its subsidiaries is subject (each, an "EXISTING
INSTRUMENT"), except for such Defaults as would not, individually or in the
aggregate, result in a Material Adverse Change. The Company's execution,
delivery and performance of this Agreement and consummation of the transactions
contemplated hereby and by the Prospectus (i) have been duly authorized by all
necessary corporate action and will not result in any violation of the
provisions of the charter or by-laws of the Company or any subsidiary, (ii) will
not conflict with or constitute a breach of, or Default under, or result in the
creation or imposition of any lien, charge or encumbrance upon any property or
assets of the Company or any of its subsidiaries pursuant to, or require the
consent of any other party to, any Existing Instrument, except for such
conflicts, breaches, Defaults, liens, charges or encumbrances as would not,
individually or in the aggregate, result in a Material Adverse Change and (iii)
will not result in any violation of any law, administrative regulation or
administrative or court decree applicable to the Company or any subsidiary. No
consent, approval, authorization or other order of, or registration or filing
with, any court or other governmental or regulatory authority or agency, is
required for the Company's execution, delivery and performance of this Agreement
and consummation of the transactions contemplated hereby and by the Prospectus,
except such as have been obtained or made by the Company and are in full force
and effect under the Securities Act, applicable state securities or blue sky
laws and from the National Association of Securities Dealers, Inc. ("NASD").

         (m) No Material Actions or Proceedings. There are no legal or
governmental actions, suits or proceedings pending or, to the best of the
Company's knowledge, threatened (i) against or affecting the Company or any of
its subsidiaries, (ii) which has as the subject thereof any officer or director
of, or property owned or leased by, the Company or any of its subsidiaries or
(iii) relating to environmental or discrimination matters, where in any such
case (A) there is a reasonable possibility that such action, suit or proceeding
might be determined adversely to the Company or such subsidiary and (B) any such
action, suit or proceeding, if so determined adversely, would reasonably be
expected to result in a Material Adverse Change or adversely affect the
consummation of the transactions contemplated by this Agreement. No material
labor dispute with the employees of the Company or any of its subsidiaries, or
with the employees of any principal supplier of the Company, exists or, to the
best of the Company's knowledge, is threatened or imminent.



                                       5


         (n) Intellectual Property Rights. The Company and its subsidiaries own
or possess sufficient trademarks, trade names, patent rights, copyrights, domain
names, licenses, approvals, trade secrets and other similar rights
(collectively, "INTELLECTUAL PROPERTY RIGHTS") reasonably necessary to conduct
their businesses as now conducted; and the expected expiration of any of such
Intellectual Property Rights would not result in a Material Adverse Change.
Neither the Company nor any of its subsidiaries has received any notice of
infringement or conflict with asserted Intellectual Property Rights of others,
which infringement or conflict, if the subject of an unfavorable decision, would
result in a Material Adverse Change. The Company is not a party to or bound by
any options, licenses or agreements with respect to the Intellectual Property
Rights of any other person or entity that are required to be set forth in the
Prospectus and are not described in all material respects. None of the
technology employed by the Company has been obtained or is being used by the
Company in violation of any contractual obligation binding on the Company or, to
the Company's knowledge, any of its officers, directors or employees or
otherwise in violation of the rights of any persons.

         (o) All Necessary Permits, etc. The Company and each subsidiary possess
such valid and current certificates, authorizations or permits issued by the
appropriate state, federal or foreign regulatory agencies or bodies necessary to
conduct their respective businesses, and neither the Company nor any subsidiary
has received any notice of proceedings relating to the revocation or
modification of, or non-compliance with, any such certificate, authorization or
permit which, singly or in the aggregate, if the subject of an unfavorable
decision, ruling or finding, could result in a Material Adverse Change.

         (p) Title to Properties. The Company and each of its subsidiaries has
good and marketable title to all the properties and assets reflected as owned in
the financial statements referred to in Section 1(i) above (or elsewhere in the
Prospectus), in each case free and clear of any security interests, mortgages,
liens, encumbrances, equities, claims and other defects, except for those
created pursuant to the Loan Agreement described in Section 1(l) and such as do
not materially and adversely affect the value of such property and do not
materially interfere with the use made or proposed to be made of such property
by the Company or such subsidiary. The real property, improvements, equipment
and personal property held under lease by the Company or any subsidiary are held
under valid and enforceable leases, with such exceptions as are not material and
do not materially interfere with the use made or proposed to be made of such
real property, improvements, equipment or personal property by the Company or
such subsidiary.

         (q) Tax Law Compliance. The Company and its subsidiaries have filed all
necessary federal, state and foreign income and franchise tax returns or have
properly requested extensions thereof and have paid all taxes required to be
paid by any of them and, if due and payable, any related or similar assessment,
fine or penalty levied against any of them except as may be being contested in
good faith and by appropriate proceedings. The Company has made adequate
charges, accruals and reserves in the applicable financial statements referred
to in Section 1(i) above in respect of all federal, state and foreign income and
franchise taxes for all periods as to which the tax liability of the Company or
any of its subsidiaries has not been finally determined.

         (r) Company Not an "Investment Company". The Company has been advised
of the rules and requirements under the Investment Company Act of 1940, as
amended (the "INVESTMENT COMPANY ACT"). The Company is not, and after receipt of
payment for the



                                       6


Common Shares will not be, an "investment company" within the meaning of
Investment Company Act and will conduct its business in a manner so that it will
not become subject to the Investment Company Act.

         (s) Insurance. Each of the Company and its subsidiaries are insured by
recognized, financially sound and reputable institutions with policies in such
amounts and with such deductibles and covering such risks as the Company
considers adequate and customary for their businesses including, but not limited
to, policies covering real and personal property owned or leased by the Company
and its subsidiaries against theft, damage, destruction, acts of vandalism and
earthquakes. The Company has no reason to believe that it or any subsidiary will
not be able (i) to renew its existing insurance coverage as and when such
policies expire or (ii) to obtain comparable coverage from similar institutions
as may be necessary or appropriate to conduct its business as now conducted and
at a cost that would not result in a Material Adverse Change. Neither of the
Company nor any subsidiary has been denied any insurance coverage which it has
sought or for which it has applied within the past three years.

         (t) No Price Stabilization or Manipulation. The Company has not taken
and will not take, directly or indirectly, any action designed to or that might
be reasonably expected to cause or result in stabilization or manipulation of
the price of any security of the Company to facilitate the sale or resale of the
Common Shares.

         (u) Related Party Transactions. There are no business relationships or
related-party transactions involving the Company or any subsidiary or any other
person required to be described in the Prospectus which have not been described
as required.

         (v) Disclosure Controls and Procedures. The Company has established and
maintains disclosure controls and procedures (as such term is defined in Rule
13a-14 under the Exchange Act), which (i) are designed to ensure that material
information relating to the Company, including its consolidated subsidiaries, is
made known to the Company's principal executive officer and its principal
financial officer by others within those entities, particularly during the
periods in which the periodic reports required under the Exchange Act are being
prepared, (ii) have been evaluated for effectiveness as of a date within 90 days
prior to the filing of the Company's most recent annual or quarterly report
filed with the Commission and (iii) are effective in all material respects to
perform the functions for which they were established. Based on the evaluation
of the Company's disclosure controls and procedures described above, the Company
is not aware of (a) any significant deficiency in the design or operation of
internal controls which could adversely affect the Company's ability to record,
process, summarize and report financial data or any material weaknesses in
internal controls or (b) any fraud, whether or not material, that involves
management or other employees who have a significant role in the Company's
internal controls. Since the most recent evaluation of the Company's disclosure
controls and procedures described above, there have been no significant changes
in internal controls or in other factors that could significantly affect
internal controls.

         (w) No Unlawful Contributions or Other Payments. Neither the Company
nor any of its subsidiaries nor, to the best of the Company's knowledge, any
employee or agent of the Company or any subsidiary, has made any contribution or
other payment to any official of, or



                                       7


candidate for, any federal, state or foreign office in violation of any law or
of the character required to be disclosed in the Prospectus.

         (x) Exchange Act Compliance. The documents incorporated or deemed to be
incorporated by reference in the Prospectus, at the time they were or hereafter
are filed with the Commission, complied and will comply in all material respects
with the requirements of the Exchange Act, and, when read together with the
other information in the Prospectus, at the time the Registration Statement and
any amendments thereto become effective and at the First Closing Date and the
Second Closing Date, as the case may be, will not 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 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.

         (y) Accounting System. The Company maintains a system of accounting
controls sufficient to provide reasonable assurances that (i) transactions are
executed in accordance with management's general or specific authorization; (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles as
applied in the United States and to maintain accountability for assets; (iii)
access to assets is permitted only in accordance with management's general or
specific authorization; and (iv) the recorded accountability for assets is
compared with existing assets at reasonable intervals and appropriate action is
taken with respect to any differences.

         (z) Compliance with Environmental Laws. Except as would not,
individually or in the aggregate, result in a Material Adverse Change (i)
neither the Company nor any of its subsidiaries is in violation of any federal,
state, local or foreign law or regulation relating to pollution or protection of
human health or the environment (including, without limitation, ambient air,
surface water, groundwater, land surface or subsurface strata) or wildlife,
including without limitation, laws and regulations relating to emissions,
discharges, releases or threatened releases of chemicals, pollutants,
contaminants, wastes, toxic substances, hazardous substances, petroleum and
petroleum products (collectively, "MATERIALS OF ENVIRONMENTAL CONCERN"), or
otherwise relating to the manufacture, processing, distribution, use, treatment,
storage, disposal, transport or handling of Materials of Environmental Concern
(collectively, "ENVIRONMENTAL LAWS"), which violation includes, but is not
limited to, noncompliance with any permits or other governmental authorizations
required for the operation of the business of the Company or its subsidiaries
under applicable Environmental Laws, or noncompliance with the terms and
conditions thereof, nor has the Company or any of its subsidiaries received any
written communication, whether from a governmental authority, citizens group,
employee or otherwise, that alleges that the Company or any of its subsidiaries
is in violation of any Environmental Law; (ii) there is no claim, action or
cause of action filed with a court or governmental authority, no investigation
with respect to which the Company has received written notice, and no written
notice by any person or entity alleging potential liability for investigatory
costs, cleanup costs, governmental responses costs, natural resources damages,
property damages, personal injuries, attorneys' fees or penalties arising out
of, based on or resulting from the presence, or release into the environment, of
any Material of Environmental Concern at any location owned, leased or operated
by the Company or any of its subsidiaries, now or in the past (collectively,
"ENVIRONMENTAL CLAIMS"), pending or, to the best of the Company's knowledge,
threatened against the Company or any of its subsidiaries or any person or
entity whose liability for any



                                       8


Environmental Claim the Company or any of its subsidiaries has retained or
assumed either contractually or by operation of law; and (iii) to the best of
the Company's knowledge, there are no past or present actions, activities,
circumstances, conditions, events or incidents, including, without limitation,
the release, emission, discharge, presence or disposal of any Material of
Environmental Concern, that reasonably could result in a violation of any
Environmental Law or form the basis of a potential Environmental Claim against
the Company or any of its subsidiaries or against any person or entity whose
liability for any Environmental Claim the Company or any of its subsidiaries has
retained or assumed either contractually or by operation of law.

         (aa) Periodic Review of Costs of Environmental Compliance. In the
ordinary course of its business, the Company reviews at times it believes are
appropriate the effect of Environmental Laws on the business, operations and
properties of the Company and its subsidiaries and identifies and evaluates
associated costs and liabilities (including, without limitation, any capital or
operating expenditures required for clean-up, closure of properties or
compliance with Environmental Laws or any permit, license or approval, any
related constraints on operating activities and any potential liabilities to
third parties). On the basis of such review and the amount of its established
reserves, the Company has reasonably concluded that such associated costs and
liabilities would not, individually or in the aggregate, result in a Material
Adverse Change.

         (bb) ERISA Compliance. The Company and its subsidiaries and any
"EMPLOYEE BENEFIT PLAN" (as defined under the Employee Retirement Income
Security Act of 1974, as amended, and the regulations and published
interpretations thereunder (collectively, "ERISA")) established or maintained by
the Company, its subsidiaries or their "ERISA AFFILIATES" (as defined below) are
in compliance in all material respects with ERISA. "ERISA AFFILIATE" means, with
respect to the Company or a subsidiary, any member of any group of organizations
described in Sections 414(b),(c),(m) or (o) of the Internal Revenue Code of
1986, as amended, and the regulations and published interpretations thereunder
(the "CODE") of which the Company or such subsidiary is a member. No "REPORTABLE
EVENT" (as defined under ERISA) has occurred or is reasonably expected to occur
with respect to any "EMPLOYEE BENEFIT PLAN" established or maintained by the
Company, its subsidiaries or any of their ERISA Affiliates. No "EMPLOYEE BENEFIT
PLAN" established or maintained by the Company, its subsidiaries or any of their
ERISA Affiliates, if such "EMPLOYEE BENEFIT PLAN" were terminated, would have
any "AMOUNT OF UNFUNDED BENEFIT LIABILITIES" (as defined under ERISA). Neither
the Company, its subsidiaries nor any of their ERISA Affiliates has incurred or
reasonably expects to incur any liability under (i) Title IV of ERISA with
respect to termination of, or withdrawal from, any "EMPLOYEE BENEFIT PLAN" or
(ii) Sections 412, 4971, 4975 or 4980B of the Code. Each "EMPLOYEE BENEFIT PLAN"
established or maintained by the Company, its subsidiaries or any of their ERISA
Affiliates that is intended to be qualified under Section 401(a) of the Code is
so qualified and nothing has occurred, whether by action or failure to act,
which would cause the loss of such qualification.

         (cc) Brokers. There is no broker, finder or other party (other than the
Underwriters) that is entitled to receive from the Company any brokerage or
finder's fee or other fee or commission as a result of any transactions
contemplated by this Agreement.

         (dd) No Outstanding Loans or Other Indebtedness. There are no
outstanding loans, advances (except normal advances for business expenses in the
ordinary course of business) or



                                       9


guarantees or indebtedness by the Company to or for the benefit of any of the
officers or directors of the Company or any of the members of any of them,
except as disclosed in the Prospectus.

         (ee) Compliance with Laws. The Company has not been advised, and has no
reason to believe, that it and each of its subsidiaries are not conducting
business in compliance with all applicable laws, rules and regulations of the
jurisdictions in which it is conducting business, except where failure to be so
in compliance would not result in a Material Adverse Change.

         (ff) Compliance with Sarbanes-Oxley Act of 2002. The Company, its
officers and directors are in material compliance with applicable effective
provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations
promulgated in connection therewith (the "SARBANES-OXLEY ACT"), and are actively
taking steps to ensure that they will be in material compliance with other
applicable provisions of the Sarbanes-Oxley Act upon their effectiveness.

         Any certificate signed by an officer of the Company and delivered to
the Representative or to counsel for the Underwriters shall be deemed to be a
representation and warranty by the Company to each Underwriter as to the matters
set forth therein.

         The Company acknowledges that the Underwriters and, for purposes of the
opinions to be delivered pursuant to Section 5 hereof, counsel to the Company
and counsel to the Underwriters, will rely upon the accuracy and truthfulness of
the foregoing representations and hereby consents to such reliance.

         SECTION 2. Purchase, Sale and Delivery of the Common Shares.

         (a) The Firm Common Shares. The Company agrees to issue and sell to the
several Underwriters the Firm Common Shares upon the terms herein set forth. On
the basis of the representations, warranties and agreements herein contained,
and upon the terms but subject to the conditions herein set forth, the
Underwriters agree, severally and not jointly, to purchase from the Company the
respective number of Firm Common Shares set forth opposite their names on
Schedule A. The purchase price per Firm Common Share to be paid by the several
Underwriters to the Company shall be $21.07 per share.

         (b) The First Closing Date. Delivery of certificates for the Firm
Common Shares to be purchased by the Underwriters and payment therefor shall be
made at the offices of Shearman & Sterling LLP, 599 Lexington Avenue, New York,
New York 10022 (or such other place as may be agreed to by the Company and the
Representative) at 9:00 a.m. New York time, on December 15, 2003, or such other
time and date not later than 1:30 p.m. New York time, on December 30, 2003 as
the Representative shall designate by notice to the Company (the time and date
of such closing are called the "FIRST CLOSING DATE"). The Company hereby
acknowledges that circumstances under which the Representative may provide
notice to postpone the First Closing Date as originally scheduled include, but
are in no way limited to, any determination by the Company or the Representative
to recirculate to the public copies of an amended or supplemented Prospectus or
a delay as contemplated by the provisions of Section 10.

         (c) The Optional Common Shares; the Second Closing Date. In addition,
on the basis of the representations, warranties and agreements herein contained,
and upon the terms but subject



                                       10


to the conditions herein set forth, the Company hereby grants an option to the
several Underwriters to purchase, severally and not jointly, up to an aggregate
of 300,000 Optional Common Shares from the Company at the purchase price per
share to be paid by the Underwriters for the Firm Common Shares. The option
granted hereunder is for use by the Underwriters solely in covering any
over-allotments in connection with the sale and distribution of the Firm Common
Shares. The option granted hereunder may be exercised at any time (but not more
than once) upon notice by the Representative to the Company, which notice may be
given at any time within 30 days from the date of this Agreement. Such notice
shall set forth (i) the aggregate number of Optional Common Shares as to which
the Underwriters are exercising the option, (ii) the names and denominations in
which the certificates for the Optional Common Shares are to be registered and
(iii) the time, date and place at which such certificates will be delivered
(which time and date may be simultaneous with, but not earlier than, the First
Closing Date; and in such case the term "FIRST CLOSING DATE" shall refer to the
time and date of delivery of certificates for the Firm Common Shares and the
Optional Common Shares). Such time and date of delivery, if subsequent to the
First Closing Date, is called the "SECOND CLOSING DATE" and shall be determined
by the Representative and shall not be earlier than three nor later than five
full business days after delivery of such notice of exercise. If any Optional
Common Shares are to be purchased, each Underwriter agrees, severally and not
jointly, to purchase the number of Optional Common Shares (subject to such
adjustments to eliminate fractional shares as the Representative may determine)
that bears the same proportion to the total number of Optional Common Shares to
be purchased as the number of Firm Common Shares set forth on Schedule A
opposite the name of such Underwriter bears to the total number of Firm Common
Shares. The Representative may cancel the option at any time prior to its
expiration by giving written notice of such cancellation to the Company.

         (d) Public Offering of the Common Shares. The Representative hereby
advises the Company that the Underwriters intend to offer for sale to the
public, as described in the Prospectus, their respective portions of the Common
Shares as soon after this Agreement has been executed as the Representative, in
its sole judgment, has determined is advisable and practicable.

         (e) Payment for the Common Shares. Payment for the Common Shares shall
be made at the First Closing Date (and, if applicable, at the Second Closing
Date) by wire transfer of immediately available funds to the order of the
Company.

         It is understood that the Representative has been authorized, for its
own account and the accounts of the several Underwriters, to accept delivery of
and receipt for, and make payment of the purchase price for, the Firm Common
Shares and any Optional Common Shares the Underwriters have agreed to purchase.
BAS, individually and not as the Representative of the Underwriters, may (but
shall not be obligated to) make payment for any Common Shares to be purchased by
any Underwriter whose funds shall not have been received by the Representative
by the First Closing Date or the Second Closing Date, as the case may be, for
the account of such Underwriter, but any such payment shall not relieve such
Underwriter from any of its obligations under this Agreement.

         (f) Delivery of the Common Shares. The Company shall deliver, or cause
to be delivered, to the Representative for the accounts of the several
Underwriters certificates for the



                                       11


Firm Common Shares at the First Closing Date, against the irrevocable release of
a wire transfer of immediately available funds for the amount of the purchase
price therefor. The Company shall also deliver, or cause to be delivered, to the
Representative for the accounts of the several Underwriters, certificates for
the Optional Common Shares the Underwriters have agreed to purchase at the First
Closing Date or the Second Closing Date, as the case may be, against the
irrevocable release of a wire transfer of immediately available funds for the
amount of the purchase price therefor. The certificates for the Common Shares
shall be in definitive form and registered in such names and denominations as
the Representative shall have requested at least two full business days prior to
the First Closing Date (or the Second Closing Date, as the case may be) and
shall be made available for inspection on the business day preceding the First
Closing Date (or the Second Closing Date, as the case may be) at a location in
New York City as the Representative may designate. Time shall be of the essence,
and delivery at the time and place specified in this Agreement is a further
condition to the obligations of the Underwriters.

         (g) Delivery of Prospectus to the Underwriters. Not later than 12:00
p.m. on the second business day following the date the Common Shares are first
released by the Underwriters for sale to the public, the Company shall deliver
or cause to be delivered, copies of the Prospectus in such quantities and at
such places as the Representative shall request.

         SECTION 3. Additional Covenants of the Company.

         Covenants of the Company. The Company further covenants and agrees with
each Underwriter as follows:

         (a) Representative's Review of Proposed Amendments and Supplements.
During such period beginning on the date hereof and ending on the later of the
First Closing Date or such date, as in the opinion of counsel for the
Underwriters, the Prospectus is no longer required by law to be delivered in
connection with sales by an Underwriter or dealer (the "PROSPECTUS DELIVERY
PERIOD"), prior to amending or supplementing the Registration Statement
(including any registration statement filed under Rule 462(b) under the
Securities Act) or the Prospectus (including any amendment or supplement through
incorporation by reference of any report filed under the Exchange Act), the
Company shall furnish to the Representative for review a copy of each such
proposed amendment or supplement, and the Company shall not file any such
proposed amendment or supplement to which the Representative reasonably objects.

         (b) Securities Act Compliance. After the date of this Agreement, the
Company shall promptly advise the Representative in writing (i) of the receipt
of any comments of, or requests for additional or supplemental information from,
the Commission, (ii) of the time and date of any filing of any post-effective
amendment to the Registration Statement or any amendment or supplement to any
preliminary prospectus or the Prospectus, (iii) of the time and date that any
post-effective amendment to the Registration Statement becomes effective and
(iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or any post-effective amendment
thereto or of any order preventing or suspending the use of any preliminary
prospectus or the Prospectus, or of any proceedings to remove, suspend or
terminate from listing or quotation the Common Stock from any securities
exchange upon which it is listed for trading or included or designated for
quotation, or of the threatening or initiation of any proceedings for any of
such purposes. If the Commission shall enter any such stop order at



                                       12


any time, the Company will use its best efforts to obtain the lifting of such
order at the earliest possible moment. Additionally, the Company agrees that it
shall comply with the provisions of Rules 424(b), 430A and 434, as applicable,
under the Securities Act and will use its reasonable efforts to confirm that any
filings made by the Company under such Rule 424(b) were received in a timely
manner by the Commission.

         (c) Amendments and Supplements to the Prospectus and Other Securities
Act Matters. If, during the Prospectus Delivery Period, any event shall occur or
condition exist as a result of which it is necessary to amend or supplement the
Prospectus in order to make the statements therein, in the light of the
circumstances when the Prospectus is delivered to a purchaser, not misleading,
or if in the opinion of the Representative or counsel for the Underwriters it is
otherwise necessary to amend or supplement the Prospectus to comply with law,
the Company agrees to promptly prepare (subject to Section 3(a) hereof), file
with the Commission and furnish at its own expense to the Underwriters and to
dealers, amendments or supplements to the Prospectus so that the statements in
the Prospectus as so amended or supplemented will not, in the light of the
circumstances when the Prospectus is delivered to a purchaser, be misleading or
so that the Prospectus, as amended or supplemented, will comply with law.

         (d) Copies of any Amendments and Supplements to the Prospectus. The
Company agrees to furnish the Representative, without charge, during the
Prospectus Delivery Period, as many copies of the Prospectus and any amendments
and supplements thereto (including any documents incorporated or deemed
incorporated by reference therein) as the Representative may reasonably request.

         (e) Blue Sky Compliance. The Company shall cooperate with the
Representative and counsel for the Underwriters to qualify or register the
Common Shares for sale under (or obtain exemptions from the application of) the
state securities or blue sky laws or Canadian provincial Securities laws of
those jurisdictions designated by the Representative, shall comply with such
laws and shall continue such qualifications, registrations and exemptions in
effect so long as required for the distribution of the Common Shares. The
Company shall not be required to qualify as a foreign corporation or to take any
action that would subject it to general service of process in any such
jurisdiction where it is not presently qualified or where it would be subject to
taxation as a foreign corporation. The Company will advise the Representative
promptly of the suspension of the qualification or registration of (or any such
exemption relating to) the Common Shares for offering, sale or trading in any
jurisdiction or any initiation or threat of any proceeding for any such purpose,
and in the event of the issuance of any order suspending such qualification,
registration or exemption, the Company shall use its best efforts to obtain the
withdrawal thereof at the earliest possible moment.

         (f) Use of Proceeds. The Company shall apply the net proceeds from the
sale of the Common Shares sold by it in the manner described under the caption
"USE OF PROCEEDS" in the Prospectus.

         (g) Transfer Agent. The Company shall engage and maintain, at its
expense, a registrar and transfer agent for the Common Stock.



                                       13


         (h) Earnings Statement. As soon as practicable, the Company will make
generally available to its security holders and to the Representative an
earnings statement (which need not be audited) covering the twelve-month period
ending March 31, 2005. That satisfies the provisions of Section 11(a) of the
Securities Act.

         (i) Periodic Reporting Obligations. During the Prospectus Delivery
Period the Company shall file, on a timely basis, with the Commission and the
New York Stock Exchange all reports and documents required to be filed under the
Exchange Act.

         (j) Company to Provide Interim Financial Statements. Prior to the
Closing Date, the Company will furnish the Underwriters, as soon as they have
been prepared by or are available to the Company, a copy of any unaudited
interim financial statements of the Company for any period subsequent to the
period covered by the most recent financial statements appearing in the
Registration Statement and the Prospectus.

         (k) Listing. The Company will use its best efforts to list, subject to
notice of issuance, the Common Shares on the New York Stock Exchange.

         (l) Agreement Not to Offer or Sell Additional Securities. During the
period commencing on the date hereof and ending on the 60th day following the
date of the Prospectus, the Company will not, without the prior written consent
of BAS (which consent may be withheld at the sole discretion of BAS), directly
or indirectly, sell, offer, contract or grant any option to sell, pledge,
transfer or establish an open "PUT EQUIVALENT POSITION" within the meaning of
Rule 16a-1(h) under the Exchange Act, or otherwise dispose of or transfer, or
announce the offering of, or file any registration statement under the
Securities Act in respect of, any shares of Common Stock, options or warrants to
acquire shares of the Common Stock or securities exchangeable or exercisable for
or convertible into shares of Common Stock (other than as contemplated by this
Agreement with respect to the Common Shares); provided, however, that the
Company may issue shares of its Common Stock or options to purchase its Common
Stock, or Common Stock upon exercise of options, pursuant to any stock option,
stock bonus or other stock plan or arrangement described in the Prospectus.

         (m) Future Reports to the Representative. During the period of five
years hereafter the Company will furnish or make available to the Representative
at 9 West 57th Street, New York, NY 10022; Attention: Scott Van Bergh: (i) as
soon as practicable after the end of each fiscal year, copies of the Annual
Report of the Company containing the balance sheet of the Company as of the
close of such fiscal year and statements of income, stockholders' equity and
cash flows for the year then ended and the opinion thereon of the Company's
independent public or certified public accountants; (ii) as soon as practicable
after the filing thereof, copies of each proxy statement, Annual Report on Form
10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other report
filed by the Company with the Commission, the NASD or any securities exchange;
and (iii) as soon as available, copies of any report or communication of the
Company mailed generally to holders of its capital stock.

         (p) Investment Limitation. The Company shall not invest, or otherwise
use the proceeds received by the Company from its sale of the Common Shares in
such a manner as would require



                                       14


the Company or any of its subsidiaries to register as an investment company
under the Investment Company Act.

         (q) No Manipulation of Price. The Company will not take, directly or
indirectly, any action designed to cause or result in, or that has constituted
or might reasonably be expected to constitute, the stabilization or manipulation
of the price of any securities of the Company.

         (r) Exchange Act Compliance. During the Prospectus Delivery Period, the
Company will file all documents required to be filed with the Commission
pursuant to Section 13, 14 or 15 of the Exchange Act in the manner and within
the time periods required by the Exchange Act.

         BAS, on behalf of the several Underwriters, may, in its sole
discretion, waive in writing the performance by the Company of any one or more
of the foregoing covenants or extend the time for their performance.
Notwithstanding the foregoing, BAS, for the benefit of each of the other
Underwriters, agrees not to consent to any action proposed to be taken by the
Company or any other holder of the Company's securities that would otherwise be
prohibited by, or to waive compliance by the Company or any such other security
holder with the provisions of, Section 3(n) above or any lock-up agreement
delivered pursuant to Section 6(k) below without giving each of the other
Underwriters at least 17 days prior notice (or such shorter notice as each of
the other Underwriters may deem acceptable to permit compliance with applicable
provisions of NYSE Rule 472(f) restricting publication and distribution of
research and public appearances by research analysts before and after the
expiration, waiver or termination of a lock-up agreement).

         SECTION 4. Payment of Expenses. The Company agrees to pay all costs,
fees and expenses incurred in connection with the performance of its obligations
hereunder and in connection with the transactions contemplated hereby, including
without limitation (i) all expenses incident to the issuance and delivery of the

expenses of the registrar and transfer agent of the Common Stock, (iii) all
necessary issue, transfer and other stamp taxes in connection with the issuance
and sale of the Common Shares to the Underwriters, (iv) all fees and expenses of

all amendments and supplements thereto, and this Agreement, (vi) all filing
fees, attorneys' fees and expenses incurred by the Company or the Underwriters
in connection with qualifying or registering (or obtaining exemptions from the
qualification or registration of) all or any part of the Common Shares for offer
and sale under the state securities or blue sky laws or the provincial
securities laws of Canada, and, if requested by the Representative, preparing
and printing a "BLUE SKY SURVEY" or memorandum, and any supplements thereto,
advising the Underwriters of such qualifications, registrations and exemptions,
(vii) the filing fees incident to, and the reasonable fees and expenses of
counsel for the Underwriters in connection with, the NASD's review and approval
of the Underwriters' participation in the offering and distribution of the
Common Shares, (viii) the fees and expenses associated with listing the Common
Stock on the New York Stock Exchange, and (ix) all other fees, costs and
expenses referred to in Item 14 of Part II of the Registration Statement. Except
as provided in this Section 4, Section 6, Section 7 and Section 8



                                       15

Shares as provided herein on the First Closing Date and, with respect to the
Optional Common Shares, the Second Closing Date, shall be subject to the

         any notice have been given of any intended or potential downgrading or

                  (i) for the period from and after the date of this Agreement
         and prior to such Closing Date, there has not occurred any Material
         Adverse Change;

the sale to the Underwriters of the Common Shares on the First Closing Date is
not consummated because of any refusal, inability or failure on the part of the
Company to perform any agreement herein or to comply with any provision hereof,
the Company agrees to reimburse the Representative and the other Underwriters
(or such Underwriters as have terminated this Agreement with respect to
themselves), severally, upon demand for all out-of-pocket expenses that shall
have been reasonably incurred by the Representative and the Underwriters in
connection with the proposed purchase and the offering and sale of the Common
Shares, including but not limited to fees and disbursements of counsel, printing
expenses, travel expenses, postage, facsimile and telephone charges.

         SECTION 7. Indemnification.

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 and the Exchange Act against any loss, claim, damage, liability
or expense, as incurred, to which such Underwriter or such controlling person
may become subject, under the Securities Act, the Exchange Act or other federal
or state statutory law or regulation, or at common law or otherwise (including
in settlement of any litigation, if such settlement is effected with the written
consent of the Company), insofar as such loss, claim, damage, liability or
expense (or actions in respect thereof as contemplated below) arises out of or
is based (i) upon any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement, or any amendment thereto,
including any information deemed to be a part thereof pursuant to Rule 430A or

circumstances under which they were made, not misleading and to reimburse each
Underwriter and each such controlling person for any and all expenses (including
the fees and disbursements of counsel chosen by BAS) as such expenses are
reasonably incurred by such Underwriter or such controlling person in connection
with investigating, defending, settling, compromising or paying any such loss,
claim, damage, liability, expense or action; provided, however, that the
foregoing indemnity agreement shall not apply to any loss, claim, damage,
liability or expense to the extent, but only to the extent, arising out of or
based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in reliance upon and in conformity with written
information furnished to the Company by the Representative expressly for use in
the Registration Statement, any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto); and provided, further, that with respect to
any preliminary prospectus, the foregoing indemnity agreement shall not inure to
the benefit of any Underwriter from whom the person asserting any loss, claim,
damage, liability or expense purchased Common Shares, or any person controlling
such Underwriter, if copies of the Prospectus were timely delivered to the
Underwriter pursuant to Section 2 and a copy of the Prospectus (as then amended
or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Underwriter
to such person, if required by law so to have been delivered, at or prior to the
written confirmation of the sale of the Common Shares to such person, and if the
Prospectus (as so amended or supplemented) would have cured the defect giving
rise to such loss, claim, damage, liability or expense. The indemnity agreement
set forth in this Section 7(a) shall be in addition to any liabilities that the
Company may otherwise have.

         (b) Indemnification of the Company, its Directors and Officers. Each
Underwriter agrees, severally and not jointly, to indemnify and hold harmless
the Company, each of its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any such
director, officer or controlling person may become subject, under the Securities
Act, the Exchange Act, or other federal or state statutory law or regulation, or
at common law or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Underwriter), insofar as
such loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based upon any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or arises out of or is 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 not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in the Registration Statement, any preliminary
prospectus, the Prospectus (or any amendment or supplement thereto), in reliance
upon and in conformity with written information furnished to the Company by the
Representative expressly for use therein; and to reimburse the Company, or any
such director, officer or controlling person for any legal and other expense
reasonably incurred by the Company, or any such director, officer or controlling
person in connection with investigating, defending, settling, compromising or
paying any such loss, claim, damage, liability, expense or action. The Company
hereby acknowledges that the only information that the Underwriters have
furnished to the Company expressly for use in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto) are the statements set forth in Schedule B; and the Underwriters
confirm that



                                       19


such statements are correct. The indemnity agreement set forth in this Section
7(b) shall be in addition to any liabilities that each Underwriter may otherwise
have.

         (c) Notifications and Other Indemnification Procedures. Promptly after
receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 7 or to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the indemnifying party and
the indemnified party in conducting the defense of any such action or that there
may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action and approval by the
indemnified party of counsel, the indemnifying party will not be liable to such
indemnified party under this Section 7 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
accordance with the proviso to the next preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expenses of
more than one separate counsel (together with local counsel), approved by the
indemnifying party (BAS in the case of Section 7(b) and Section 8), representing
the indemnified parties who are parties to such action) or (ii) 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
commencement of the action, in each of which cases the fees and expenses of
counsel shall be at the expense of the indemnifying party.

         (d) Settlements. The indemnifying party under this Section 7 shall not
be liable for any settlement of any proceeding effected without its written
consent, but if settled with such consent or if there be a final judgment for
the plaintiff, the indemnifying party agrees to indemnify the indemnified party
against any loss, claim, damage, liability or expense by reason of such
settlement or judgment. Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by Section
7(c) hereof, the indemnifying party agrees that it shall be liable for any
settlement of any proceeding effected without its written consent if (i) such
settlement is entered into more than 30 days after receipt by such indemnifying
party of the



                                       20


aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement, compromise or consent to the entry
of judgment in any pending or threatened action, suit or proceeding in respect
of which any indemnified party is or could have been a party and indemnity was
or could have been sought hereunder by such indemnified party, unless such
settlement, compromise or consent includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

         SECTION 8. Contribution. If the indemnification provided for in Section
7 is for any reason held to be unavailable to or otherwise insufficient to hold
harmless an indemnified party in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount paid or payable by such indemnified party, as
incurred, as a result of any losses, claims, damages, liabilities or expenses
referred to therein (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, on the one hand, and the
Underwriters, on the other hand, from the offering of the Common Shares pursuant
to this Agreement 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 hand,
in connection with the statements or omissions which resulted in such losses,
claims, damages, liabilities or expenses, 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 hand, in connection with the
offering of the Common Shares pursuant to this Agreement shall be deemed to be
in the same respective proportions as the total net proceeds from the offering
of the Common Shares pursuant to this Agreement (before deducting expenses)
received by the Company, and the total discount received by the Underwriters
bear to the aggregate initial offering price of the Common Shares. The relative
fault of the Company, on the one hand, and the Underwriters, on the other hand,
shall be determined by reference to, among other things, whether any such 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, on the other hand, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

         The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 7(c), any legal or
other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in
Section 7(c) with respect to notice of commencement of any action shall apply if
a claim for contribution is to be made under this Section 8; provided, however,
that no additional notice shall be required with respect to any action for which
notice has been given under Section 7(c) for purposes of indemnification.

         The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 8 were 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 account of the
equitable considerations referred to in this Section 8.



                                       21


         Notwithstanding the provisions of this Section 8, no Underwriter shall
be required to contribute any amount in excess of the underwriting commissions
received by such Underwriter in connection with the Common Shares underwritten
by it and distributed to the public. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section 8 are several, and not joint, in proportion to their
respective underwriting commitments as set forth opposite their names in
Schedule A. For purposes of this Section 8, each officer and employee of an
Underwriter and each person, if any, who controls an Underwriter within the
meaning of the Securities Act and the Exchange Act shall have the same rights to
contribution as such Underwriter, and each director of the Company, each officer
of the Company who signed the Registration Statement, and each person, if any,
who controls the Company with the meaning of the Securities Act and the Exchange
Act shall have the same rights to contribution as the Company.

         SECTION 9. Default of One or More of the Several Underwriters. If, on
the First Closing Date or the Second Closing Date, as the case may be, any one
or more of the several Underwriters shall fail or refuse to purchase Common
Shares that it or they have agreed to purchase hereunder on such date, and the
aggregate number of Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase does not exceed 10% of the
aggregate number of the Common Shares to be purchased on such date, the other
Underwriters shall be obligated, severally, in the proportions that the number
of Firm Common Shares set forth opposite their respective names on Schedule A
bears to the aggregate number of Firm Common Shares set forth opposite the names
of all such non-defaulting Underwriters, or in such other proportions as may be
specified by the Representative with the consent of the non-defaulting
Underwriters, to purchase the Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the Underwriters shall fail or refuse to purchase Common Shares and the
aggregate number of Common Shares with respect to which such default occurs
exceeds 10% of the aggregate number of Common Shares to be purchased on such
date, and arrangements satisfactory to the Representative and the Company for
the purchase of such Common Shares are not made within 48 hours after such
default, this Agreement shall terminate without liability of any party to any
other party except that the provisions of Section 4, Section 7 and Section 8
shall at all times be effective and shall survive such termination. In any such
case either the Representative or the Company shall have the right to postpone
the First Closing Date or the Second Closing Date, as the case may be, but in no
event for longer than seven days in order that the required changes, if any, to
the Registration Statement and the Prospectus or any other documents or
arrangements may be effected.

         As used in this Agreement, the term "UNDERWRITER" shall be deemed to
include any person substituted for a defaulting Underwriter under this Section
9. Any action taken under this Section 9 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

         SECTION 10. Termination of this Agreement. Prior to the First Closing
Date this Agreement may be terminated by the Representative by notice given to
the Company if at any time (i) trading or quotation in any of the Company's
securities shall have been suspended or



                                       22


limited by the Commission or by the NYSE, or trading in securities generally on
either the Nasdaq Stock Market or the New York Stock Exchange shall have been
suspended or limited, or minimum or maximum prices shall have been generally
established on any of such stock exchanges by the Commission or the NASD; (ii) a
general banking moratorium shall have been declared by any of federal, New York,
Delaware or Oklahoma authorities; (iii) there shall have occurred any outbreak
or escalation of national or international hostilities or any crisis or
calamity, or any change in the United States or international financial markets,
or any substantial change or development involving a prospective substantial
change in United States' or international political, financial or economic
conditions, as in the judgment of the Representative is material and adverse and
makes it impracticable to market the Common Shares in the manner and on the
terms described in the Prospectus or to enforce contracts for the sale of
securities; (iv) in the judgment of the Representative there shall have occurred
any Material Adverse Change; or (v) the Company shall have sustained a loss by
strike, fire, flood, earthquake, accident or other calamity of such character as
in the judgment of the Representative may interfere materially with the conduct
of the business and operations of the Company regardless of whether or not such
loss shall have been insured. Any termination pursuant to this Section 10 shall
be without liability on the part of (a) the Company to any Underwriter, except
that the Company shall be obligated to reimburse the expenses of the
Representative and the Underwriters pursuant to Sections 4 and 6 hereof, (b) any
Underwriter to the Company, or (c) of any party hereto to any other party except
that the provisions of Section 7 and Section 8 shall at all times be effective
and shall survive such termination.

         SECTION 11. Representations and Indemnities to Survive Delivery. The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers and of the several Underwriters 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 any Underwriter
or the Company or any of its or their partners, officers or directors or any
controlling person, as the case may be, and will survive delivery of and payment
for the Common Shares sold hereunder and any termination of this Agreement.

         SECTION 12. Notices. All communications hereunder shall be in writing

obligation hereunder. The term "SUCCESSORS" shall not include any purchaser of
the Common Shares as such from any of the Underwriters merely by reason of such
purchase.

         SECTION 14. Partial Unenforceability. The invalidity or
unenforceability of any Section, paragraph or provision of this Agreement shall
not affect the validity or enforceability of any other Section, paragraph or

make it valid and enforceable.

         SECTION 15. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK

                                       24


         (a) Consent to Jurisdiction. Any legal suit, action or proceeding
arising out of or based upon this Agreement or the transactions contemplated
hereby ("RELATED PROCEEDINGS") may be instituted in the federal courts of the
United States of America located in the City and County of New York or the
courts of the State of New York in each case located in the City and County of
New York (collectively, the "SPECIFIED COURTS"), and each party irrevocably
submits to the non-exclusive jurisdiction of such courts in any such suit,
action or proceeding. Service of any process, summons, notice or document by
mail to such party's address set forth above shall be effective service of
process for any suit, action or other proceeding brought in any such court. The
parties irrevocably and unconditionally waive any objection to the laying of
venue of any suit, action or other proceeding in the Specified Courts and
irrevocably and unconditionally waive and agree not to plead or claim in any
such court that any such suit, action or other proceeding brought in any such
court has been brought in an inconvenient forum.

         SECTION 16. General Provisions. This Agreement constitutes the entire
agreement of the parties to this Agreement and supersedes all prior written or
oral and all contemporaneous oral agreements, understandings and negotiations
with respect to the subject matter hereof. This Agreement may be executed in two
or more counterparts, each one of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement may not be amended or modified unless in writing by all of the
parties hereto, and no condition herein (express or implied) may be waived
unless waived in writing by each party whom the condition is meant to benefit.
The Section headings herein are for the convenience of the parties only and
shall not affect the construction or interpretation of this Agreement.

         Each of the parties hereto acknowledges that it is a sophisticated
business person who was adequately represented by counsel during negotiations
regarding the provisions hereof, including, without limitation, the
indemnification provisions of Section 7 and the contribution provisions of
Section 8, and is fully informed regarding said provisions. Each of the parties
hereto further acknowledges that the provisions of Sections 7 and 8 hereto
fairly allocate the risks in light of the ability of the parties to investigate
the Company, its affairs and its business in order to assure that adequate
disclosure has been made in the Registration Statement, any preliminary
prospectus and the Prospectus (and any amendments and supplements thereto), as
required by the Securities Act and the Exchange Act.

         The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company and the several Underwriters set
forth in or made pursuant to this Agreement shall remain operative and in full
force and effect, regardless of (i) any investigation, or statement as to the
results thereof, made by or on behalf of any Underwriter, the officers or
employees of any Underwriter, any person controlling any Underwriter, the
Company, the officers or employees of the Company, or any person controlling the
Company, (ii) acceptance of the Shares and payment for them hereunder and (iii)
termination of this Agreement.

         Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the Company, the
Underwriters, the Underwriters' officers and employees, any controlling persons
referred to herein, the Company's directors and the Company's officers who sign
the Registration Statement and their respective successors and assigns, all as
and to the extent provided in this Agreement, and no other person shall acquire
or



                                       25


have any right under or by virtue of this Agreement. The term "SUCCESSORS AND
ASSIGNS" shall not include a purchaser of any of the Shares from any of the
several Underwriters merely because of such purchase.

                            [SIGNATURE PAGE FOLLOWS]





                                       26

transact business and is in good standing in the State of Delaware and in each
other jurisdiction in which such qualification is required, whether by reason of
the ownership or leasing of property or the conduct of business, except for such

a Material Adverse Change.

Company and the performance by the Company of its obligations thereunder (other

section of the Underwriting Agreement, as to which no opinion need be rendered)
(i) have been duly authorized by all necessary corporate action on the part of
the Company; (ii) will not result in any violation of the provisions of the
charter or by-laws of the Company or any subsidiary; (iii) will not constitute a
breach of, or Default under, or result in the creation or imposition of any
lien, charge or encumbrance upon any property or assets of the Company or any of
its subsidiaries pursuant to, (A) the Loan Agreement, dated as of July 24, 2001,
by and among (1) the Company, Mountain Front Pipeline Company, Inc., Unit

         (xix) Except as disclosed in the Prospectus, to the best knowledge of
such counsel, there are no persons with registration or other similar rights to
have any equity or debt securities registered for sale under the Registration
Statement or included in the offering contemplated by the Underwriting
Agreement, except for such rights as have been duly waived.

         (xx) To the best knowledge of such counsel, neither the Company nor any
significant subsidiary is in violation of its charter or by-laws or any law,
administrative regulation or administrative or court decree applicable to the
Company or any subsidiary or is in Default in the performance or observance of
any obligation, agreement, covenant or condition contained in any material
Existing Instrument, except in each such case for such violations or Defaults as
would not, individually or in the aggregate, result in a Material Adverse
Change.

         (xxi) Each document filed pursuant to the Exchange Act (other than the
financial statements, statistical data, oil and gas reserve information and
supporting schedules included therein, as to which no opinion need be rendered)
and incorporated or deemed to be incorporated by reference in the Prospectus
complied when so filed as to form in all material respects with the Exchange
Act.

         In addition, such counsel shall state that they have participated in
conferences with officers and other representatives of the Company,
representatives of the independent public or certified public accountants for
the Company and with representatives of the Underwriters at which the contents
of the Registration Statement and the Prospectus, and any supplements or
amendments thereto, and related matters were discussed and, although such
counsel is not passing upon and does not assume any responsibility for the
accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus (other than as specified in Paragraph
(xiii) above), and any supplements or amendments thereto, on the basis of the
foregoing, nothing has come to their attention which would lead them to believe
that either the Registration Statement or any amendments thereto, at the time
the Registration Statement or such amendments became effective, contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
or that the Prospectus, as of its date or at the First Closing Date or the
Second Closing Date, as the case may be, contained an untrue statement of a
material fact or omitted to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading (it being understood that such counsel need express no
belief as to the financial statements or schedules or other financial or
statistical data derived therefrom, or any of the oil and gas reserve
information included or incorporated by reference in the Registration Statement
or the Prospectus or any amendments or supplements thereto).

         In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws of any jurisdiction other than the General
Corporation Law of the State of Delaware, the laws of the State of Oklahoma or
the federal law of the United States, to the extent they deem proper and
specified in such opinion, upon the opinion (which shall be dated the First
Closing Date or the Second Closing Date, as the case may be, shall be
satisfactory in form and substance to the Underwriters, shall expressly state
that the Underwriters may rely on such opinion as if it were addressed to them
and shall be furnished to the Representative) of other counsel of good standing
whom they believe to be reliable and who are satisfactory to counsel



                                      A-4


for the Underwriters; provided, however, that such counsel shall further state
that they believe that they and the Underwriters are justified in relying upon
such opinion of other counsel, and (B) as to matters of fact, to the extent they
deem proper, on certificates of responsible officers of the Company and public
officials.
